All about snow blowers

With the onset of the winter period, there are considerable problems associated with cleaning the stag. There is a lot of rainfall every day, which can block traffic on the roadway and sidewalks. It is very difficult to clear such vast distances with human forces and manual devices. Therefore, in order to better fight the bad weather, snow blowers of various modifications come to our aid. Some of them are mounted. They can clear both freshly fallen snow and the one that has been lying for a long time.

The models that are attached include rotary auger snow blowers (SHRS). Their principle of operation is that the main drive is driven by the engine of the vehicle to which it is attached, through a gearbox and a propeller shaft. To make it more convenient to ride on impassable roads, special tires with spikes or (if necessary) caterpillars are foreseen on wheels.

When moving, the augers capture the snow, crush it and move it to the middle of the branch pipe, after which, with the help of the rotor, it is thrown out through a special chute and pipe for removing the masses at a distance of 15-25 meters. The length of the throw depends on the compaction and depth of the snow, the power of the engine of the device to which it is attached, and the speed of movement of this vehicle.

The productivity of the auger is on average about 200 tons / hour, which even increases when the snow mass is thrown to one side. There is a function of loading snow into a body or container. The design of the installation is very simple: it is attached to any low-speed tractor or machine using a special hitch, which saves time and physical costs.

Comparing SHRS with similar snow blowers, one can note their obvious advantages and disadvantages. We attribute to the advantages:

• impressive performance of snow removal;
• long throwing distance and depth of snow removed.

Disadvantages:

• enormous weight of the structure;
• small working pace of movement;
• subordination to other machines;
• high cost and inability to use out of season.

The basis of the operation of modules of this type is the same, the only difference is in the configuration and technical characteristics that you need to pay attention to when buying: this is the productivity, the corridor of the cleared area, what speed the equipment to which it is attached can develop, the density and range of snow throwing, the availability and price of spare parts to the selected model.

The characteristics of the most common models of such snow throwers should be discussed in more detail.

Small-sized snow blower MS-59 is intended for use in small areas where large-sized vehicles will not pass. It is a self-propelled unit with a portable electric control. For greater convenience, he has 2 driving wheels, 2 rollers, which, if necessary, can be exchanged for skis. Overall dimensions of the device: length - 3120 mm, width - 1030 mm, height - 1135 mm. They allow you to capture an area of ​​1000 mm during cleaning. Weighs 890 kg.

In front there is a working body - a milling-mouth device that crushes and collects snow. It was equipped with a five-speed gearbox: 4 of them provide forward movement, and 1 - backward.In addition, there are 2 additional gears in the box: for the cutter and the rotor. The snow blower is equipped with a self-contained gasoline engine, which is air-cooled and has horizontal cylinders. Its power is 14 liters. with.

When clearing the territory, the productivity of the device reaches 100 tons / hour. The device covers blockages up to 1 meter wide and high. The snow plow reaches a distance of 15 m. It is also provided for the discharge of snow to the right or to the left - depending on the movement of the purifier. By connecting the pipe and the loading hood, it can be loaded onto any vehicle. The working speed is 0.5 km / h, which when moving to another workplace can reach 8 km / h.

This rotary auger is designed for clearing snow over large areas and stale snow embankments. Widely used by utilities. It is aggregated with various tractors (with an engine power of at least 26 hp), but the most suitable for the technical characteristics of Belarus 320.4 / 422 or its modifications.

Snow blower ST-1500 is installed on the front of the tractor on a special hydraulic device, which brings it into working condition. In this case, ballast must be installed in the rear. The rotation speed during power take-off must be at least 1000 rpm.

Weighs only 250 kg. When compared with other devices of this type, then it has rather small dimensions: 950 mm in length, 1550 mm in width and 700 mm in height. This makes it possible for him to grasp the cleared snow cover up to 0.5 meters high and 1.55 meters wide. The volume of snow removal reaches 80 tons / hour - this is about 2250 sq. meters of area. When driving during operation, a speed of 3 km / h is reached. There is a function of connecting a socket, which is capable of turning 150 degrees and throwing a snow mass 20 meters into the distance.

This is a device for cleaning the coatings from the snow that has fallen out and accumulated in the rubble by throwing it aside or loading it into other cars. It is attached either to the front or rear hitch with the help of a hydraulic drive, which speaks of its versatility and allows the tractor to move forward and backward.

For this device, the main tractor models are MTZ-80, MTZ-82, MTZ-1221 with traction class 1.4. It weighs about 730 kg and differs in the following dimensions: length - 1850 mm, width - 2200 mm, height - 2310 mm in transport position, and 2060 mm in working position. Due to its dimensions, it can remove snow cover up to 0.7 meters high and capture the cleaned strip at a distance of 2.2 meters.

It also impresses with its productivity, which reaches 350 tons / hour. It is equipped with a nozzle rotating at 300 degrees with a snow throwing range of up to 20 meters. There is an adjustment of the direction of snow throw - it all depends on what working conditions. It is possible to carry out loading on the body of any other vehicle.

The drive of the working mechanism of the snow blower is mechanical, equipped with one rotor with 4 blades. The rotor has a diameter of 710 mm, and its rotation frequency reaches 540 rpm. During operation, the vehicle to which it is attached can pick up speed up to 10 km / h. No creeper required for continuous operation.

The unit of this model is designed for removing packed snow, blockages on the roads and paving the way on virgin soil. Type - hinged. It clings to tractors with a creeper. Basically it is MTZ-80/82 or MTZ-92P. Its overall dimensions are 1000x2040x920 mm, which allow removing rubble 2 m wide and 70 cm high. In addition to cleaning, the cleaner also throws snow 5–20 m. It has a mechanical drive type.During the working process, it develops a speed of up to 1 km / h and removes up to 350 cubic meters. m / hour of snow. Weighs 750 kg.
