Snowplow and rotary snowplow with their own hands. homemade for snow removal
Hand tools are gradually receding into the background when it comes to clearing snowdrifts. The fact is that modern technical thought offers special units and devices that can significantly improve not only the efficiency of cleaning, but also reduce the energy consumption of the entire process. We are talking about household snow blowers, which are available in different configuration and technical equipment (see. how to choose). These devices cost a lot of money, but to make a snowplow at home, using handy tools, pretty simple. As practice shows, the improvised means are quite good homemade devices, almost no inferior to their purchased counterparts.In this article we will talk about how to make a rotary snowplow with your own hands?
The rotor snow thrower is quite simple. The unit consists of a “snail”. a round body. A hose is placed on top for throwing snow. At the front of the body are welded guide vanes. Inside the snow blower, a rotor rotates at high speed. It consists of an impeller pinned on a shaft with bearings. The mechanism is actuated by a motor. When the snow thrower rotates the rotor blades of the impeller begin to pick up the snow, grind it inside the snail, and then throw it a few meters away through the hose. Homemade rotary snow thrower can be made in two varieties:
- With permanently installed motor. The snowblower then functions as a full-fledged machine.
- As a canopy for other equipment. On such rotor self-made models do not put a motor. The snow blower is attached to a minitractor or a power tiller. They are driven by chain or belt drive.
Rotary snow blowers are also differentiated by the type of engine:
Gasoline-powered rotary models are an order of magnitude more powerful than electric snow blowers. Their disadvantages are only more complicated maintenance of the engine, the presence of exhaust gases and regular refilling of fuel and lubricants. However, the gasoline snow blower is not tied to the connection to the power grid. The power of the engine makes it possible to produce a rotary mechanism of large dimensions. This rotary device has an increased working width and is able to cope not only with thick snow cover, but also with drifts.
According to the type of movement of rotary snow blowers are divided into: Non-propelled. Such units are moved by pushing them by the operator. This category usually includes electric snow blowers, but gasoline-powered, low-powered versions can also be found among them. The equipment needs to be pushed slightly. Due to the capture of the snow cover by the impeller, the snow blower will move forward spontaneously.Self-propelled mechanisms are most often powered by a gasoline motor. The snow blower drives itself on wheels. The operator just steers the machine.
A rotary snowblower can also be considered a self-propelled machine, although it doesn’t even have a stationary drive. But it can not be pushed by hand. The attachment will move together with the mini-tractor or power tiller.
Tools for making your own snowmaking equipment
Any work can only be performed with tools, so it is advisable to have:
- Electric drill. without it it is impossible to make holes of a given diameter in the right places;
- riveter. will help to create strong unbreakable joints in the sheet material;
- Electric welding machine. will be required for welding the frame, as well as individual units;
- Angle grinder. will be used for cutting steel workpieces, as well as stripping welded joints;
- metal scissors;
- Measuring tool. used to mark and control the parameters of the parts, as well as the entire snowblower (usually a caliper, a tape measure and a ruler is enough);
- Manual tool for fixing the parts and temporary fasteners. will allow to work qualitatively and with minimum effort;
- Slipway. even the simplest, made of wooden bars, will help simplify the assembly process, the construction of the snowthrower has a spatial design, which must be assembled by fixing individual parts and assemblies in different places.
The principle of operation of snow plows
As mentioned above, there are two main elements in the design of the machine: the motor and the working body, which is used to capture the snow. Most often, it uses an auger, which is connected to the engine through a belt or chain drive. The faster the auger rotates, the farther the machine throws the snow to the side.
In this case, the working body is divided into two sections, that is, it is divided in half. Each area has an auger with a different arrangement of blades. on one side they are positioned obliquely to the left and on the other side to the right. This is done to ensure that from the edges of the capture device snow mass flowed to the center, where it will be centralized in the assembly hopper.
It is the working body that creates two groups of snow blowers, which are divided into one-stage and two-stage.
This type cleans snow with an auger only. Hence the short throwing distance. up to 5 m. The machines have small dimensions. the width of the assembly bucket does not exceed 90 cm, and they weigh a little. up to 40 kg.
These machines belong to the category of manual machines, i.e., they are not equipped with a motor. A man just pushes the machine, from the wheels to the auger held in a chain gear.It is the driving force. The faster a man pushes the cart, the harder the machine works.
They are usually used to clean ice rinks, paths and small areas with just fallen snow of small thickness. These snow blowers mostly use rubberized parts, which quickly fail if the hand-held machine is not operated properly.
The very name says that in addition to the auger in the machine is set another working body. This impeller (wheel with blades), with which you can throw snow up to 15 m. There are models in this group with manual execution and with motor. The second option is preferable, because the machine itself weighs at least 75 kg, so it is quite difficult to move it, pushing it by hand.
This model is equipped with both electric motors, gasoline or diesel engines. They are convenient in operation, they have a more powerful design that allows you to clean up even the biggest drifts, plus auger is located so that it does not touch the hard surface of cleared planes. That is, its service life is long enough.
Speaking of snowplows for the home, made by their own hands, it is necessary to take into account the complexity of the two-stage construction. Therefore, the best option is a one-step.
Rotary snow blowers. purpose and classification
Rotary snow ploughs
Rotary snow ploughs are equipped with an active working body, usually mounted on a self-propelled chassis. Such snow ploughs are designed for clearing large and relatively thick snow masses from roads and airfields in case of irregular snow removal, removing snow rollers, clearing mountainous areas from snowfall, snow drifting and avalanche, as well as clearing snow from city streets and squares and throwing it away or loading it onto transport vehicles. According to the type of the working body, rotary snow ploughs are divided into plough-rotor, auger-rotor, cutter-rotor and combined working body.Working body of the plough-rotor snowplow consists of a plough with one or two bladed rotors built in it. The mass of snow cut by the ploughs advances along the inner liner of its body, usually made in the form of a conical surface, to the rotor(s), which throws the snow to the side. Plough-rotor snow ploughs are mainly used for working in dry loose snow with low density. The working body of the auger rotor snowplow consists of a screw feeder (with one, two or three augers) and a bladed rotor, mounted in a common housing. The augers of the feeder cut the snow out of the mass and direct it towards the rotor. The snow mass entering the rotor is thrown to the side by the rotor. Auger-rotor snowploughs work well on medium-dense and hard snow and poorly on very hard, hard and frozen snow. The working body of the cutter-rotor snowplow consists of a cutter feeder and one or two bladed rotors, mounted in a common housing. The milling feeder is designed as a drumless milling machine of large diameter with cutting elements. spiral belts fixed by means of struts and struts on the axes of the milling machines. Such a feeder has a large capacity and good cutting properties, thanks to which it can be successfully used in the development of dense and hard snow. Similar to the auger feeder, the cutter feeder cuts snow from the mass and feeds it to the rotor, which tosses it aside. The combined working body of the rotary snow plough is usually performed in the form of hollow drums, inside which are placed elements of the working body drive with right and left cutting belts winding on their outer surface along the helical line, forming s at the point of closure for receiving snow mass. As the drum rotates, the belts take the snow from the snow mass into the cavity between the outer edge of the belt and the drum surface, which, moving along the belt, enters the from the right and left turns. These snow ploughs are more compact than auger and cutter-rotor snow ploughs and can work snow of any density and strength, but are very energy-intensive, low-productive and cannot provide a greater range of snow throwing.Rotary snow blowers are subdivided into:. by type of chassis into pneumatic-wheeled and tracked;. by type of base machine. into automobile, tractor, tractor-mounted, loader and own chassis;. by performance. into light (up to 200 t/h), medium (up to 1000 t/h) and heavy (over 1000 t/h). Medium and heavy machines are subdivided in terms of snow throwing distance into road (up to 18 meters) and airfield (over 18 meters) machines. According to the number of installed engines distinguish single-engine snow ploughs with a common engine and twin-engine (in rare cases, multiengine) with separate engines to drive the course and working bodies.Initial parameters for calculation are productivity Q in t / h, the distance of snow mass throwing, the height of the developed snow layer H in meters and physical and mechanical properties of snow.
Snow blower for power tiller: principle of operation and basics of self-assembly
With the onset of cold weather the owners of country houses are forced to take up snow removal again and again. The article will tell how to make your own hands a snowplow for power tiller, the principle of operation, characteristics and features. And also tips and recommendations on selecting the best option among the models offered in the market.
A single-axle tractor is often equipped with a special snow-clearing attachment
There are positive and negative qualities of these mechanisms. We get a snow clearing machine from the tool we have, with minimal effort. The machine becomes multifunctional. But there is a disadvantage. The equipment is not designed to work in the winter, which means that its parts will wear out faster.
With these devices it is easy to clean only loose dry snow. And as you may have noticed it is necessary to tinker before collecting a working unit, and some refuse the idea to collect their own hands, but still plan to save money and for these purposes was written article in which we talk about snow blower Husqvarna 227, because in contrast to their counterparts, this product is much less.
From the same motives to save money quite simple in design and assembly with their own hands turf slicer from a washing machine.
Snow removal with a shovel is a fairly time-consuming process. To make it easier, a homemade snow blower can come to the rescue. By making it, you not only free yourself from the hard work of clearing snow, but also save a lot of money, not spending money on expensive models of factory-made.
Preparing for work
Going to make a snow removal attachment, you must first do the following:
- Choose a unit or technique for which you will make attachments-snegomet;
- Decide on the type of attachment;
- Decide on the available materials;
- Carefully read all available information on this type of attachment and installation on your chosen equipment;
- Determine what you can do yourself and what you have to buy or order.
The choice of technical device, for which you are going to make a snowplow, directly affects the type of this equipment.
For example, only a bulldozer blade is well suited for installation on a passenger car.
This is due to the very high speed of travel in first gear and average engine rpm.
To effectively throw the snow at such speed, and even with an auger length equal to the width of the car, you need a motor with at least 50 horsepower (l. с.). Accordingly, the weight of the unit will be well over 400 kilograms.
It’s impossible to build and build such a machine without solid experience. And the cost of making it will be comparable to the cost of a good self-propelled snow blower, which will be much more efficient.
For an SUV, the requirements are slightly lower if it has:
But the main problem is the same. it’s too fast and wide. After all, at such a width the optimal speed for normal operation of the auger rotor mechanism should not exceed 1-2 kilometers per hour for cleaning not too deep snow.
Therefore, the best choice for any car or any other vehicle is a dozer blade.
The situation is different with power tillers and other self-propelled machines. After all, in most cases, their minimum speed is 5-7 kilometers per hour.
If the self-propelled machine is equipped with an engine of 7-15 l. с., it is enough for cleaning not too deep snow.
When clearing deep snow, you either have to put up with slipping wheels or move the machine forward in small jerks, allowing the auger rotor mechanism to successfully grind and eject the snow.
Deciding to install a snow thrower on the equipment instead of a knife, you need to decide on its type.
The difference between the auger and auger rotor homemade snowthrower is that in the first case, the auger both shreds and disperses the snow, and in the second, only shreds.
Therefore, with the same motor power, the efficiency of an auger conveyor is at least two times higher than that of an auger conveyor.
Consequently, for normal snow removal with an auger mechanism, it is necessary to equip it with a motor at least twice as powerful.
If you decide to do with your own hands auger rotor mounted snowplow, the main problem will be finding a gearbox. After all, the gearbox from the snow blower is not less than 8 thousand.
It is possible to make such a homemade snowplow and without the classic gearbox.
But in this case you will need to find or make yourself a gear or belt drive, in which the primary and secondary shafts are rotated relative to each other by 90 degrees.
Gears can be made from two planetary gears and their axles from any car differential.
You can buy these parts at places like:
Assembling an auger snow blower
Snowmobiles based on an auger are the most powerful and able to cope even with icy snow. and the auger is most often used in self-propelled snowthrowers.
On the base of a chainsaw
This snowplow is made with their own hands is simple enough. Since it will run on the chainsaw engine, you’ll need a few additional parts for the chain drive. You can use front and rear sprockets from a motorcycle, and also a chain from it.
How to make the frame and the auger was described above. A long handle is attached to the frame. On the shaft of the auger on the right side is set a large sprocket from a motorcycle, and on the shaft of the chainsaw engine. a small one. Next, the chainsaw is installed on the frame, and then the chain is put on the sprockets and tensioned. To control the engine, the gas cable is led to the handle attached to the frame.
Below are the drawings of self-made chassis, where a chainsaw is used as the main part of the drive.
On the basis of the grass trimmer
To make a snow blower from an electric grass trimmer or lawn mower, a gearbox is needed: it will be used to transfer the rotary motion from the grass trimmer shaft to the auger shaft.
But there is a nuance here. Gearbox for this type of units is rather expensive, and it is not reasonable to buy it for making attachments to trimmers. That is why rotary snow blowers are produced on the basis of the latter.
On the basis of a power tiller (power tiller)
The easiest addition to a power tiller is a snow blade.
Homemade snowplow nozzle (shovel) on a single-axle tractor is bolted to the frame of the machine, after which it turns into a small bulldozer.
Tip! Instead of the moldboard, an auger can be attached to the front of the frame of a power tiller or motocultivator, resulting in a self-propelled snowplow. This power tiller attachment is easily detached from the main machine if it is not needed.
Below there is a scheme, which is a good illustration of snow cutter construction on the basis of a cultivator.
Here is how the schematic diagram looks like.
- The snowplow drive that connects the engine to the auger.
- Caterpillar drive.
- Drive belt.
- Roller (parasite roller) for reversing.
- Intermediate shaft.
- Roller for belt tensioning. It ensures the machine’s forward motion.
Self-propelled snow blower greatly facilitates snow removal, especially in large areas where the use of the unit on skis, pushed by the operator, requires a large expenditure of physical strength of the latter.
