Description

The inventive utility model relates to snow removal mechanisms used for snow removal from roads in winter after avalanches and large snow accumulations after snowfalls and in areas where a snow emergency regime is declared.

According to the results of the preliminary patent search closest to the claimed technical solution, not identified.

However, the ZIMA-1 snow removal device according to the utility model patent No. 139713, published on 04/20/2014, is known in the prior art. The snow removal device comprises a front shield that is fixed to the supporting structure by means of a vertical hinge. In this case, the supporting structure of the device is made in the form of a handle, the shield is fixed on the support of its own axis through an aggregating base rigidly fixed to the handle at three points. The handle is attached to the bucket and is equipped with a small stop handle. The angle of the shield is adjustable using two horizontal, manually driven, tie rods control the angle of capture of the shield. The control rods are fixed in the working position with the help of additional rods fixed on the cross-member, which is fixed on the handle with the help of the rotation axis, and which are fixed, in turn, with latches, also located on the handle. Symmetrically to the handle along the transverse axis of the shield are mounted two trapezoidal stops-stops, for the entire length of the lower plane of the bucket along its longitudinal axis there are tape slides, adjustable in tension by the cutting edge of the bucket. The known device does not allow to remove snow drifts up to three meters high.

Known rotary snow blower, utility model patent No. 58559, published November 27, 2006. The rigid structure of the rotor is made of two parts of the right and left versions in the form of a worm cutter with individual blades in 4 rows provides effective grinding of ice and contaminated snow with foreign objects. However, the rotary snow blower is designed to remove small areas from snow from soft, compacted snow and to destroy ice from the roadbed of small areas of urban sidewalks.

Known snow blower, utility model patent No. 136450, published January 10, 2014. The snow blower contains a ski case, a drive mounted thereon, a screw feeder, a rotary nozzle, a snow emission control device connected to a rotary lever mounted on the steering column of the walk-behind tractor at the same time, the screw feeder is equipped with snow ejection blades located in its central part, and the drive contains a chain drive with removable sprockets of various diameters, which allow changing the range of rotation of the screw a, and one asterisk is located on one shaft with a V-belt pulley, and the second on one shaft with a screw feeder. The utility model can be used for snow removal on sidewalks, children's, sports grounds, in yards and homestead households, but it does not allow to remove snow in large volumes.

Known snowblower, patent for invention No. 2341613, published December 20, 2008. The working body contains blades mounted on the axles between the bearing wheel and the support ring. The axes are located above the center of gravity with the possibility of rotation of the blades by the force of their gravity and the mass of a portion of snow. The working angle of the blades is set during loading and unloading automatically from exposure to a mass of snow and limiters. The receiving tray has an inner surface of cylindrical shape with runners and at the other end with the possibility of resetting to the working position, the unloading tray is made with the possibility of readjusting to another unloading position, and the handle is in the position opposite to the direction of the working movement of the snow thrower. The invention is intended for small-scale mechanization of manual labor for snow removal from pavements and sidewalks.

Known exhaust rotor (NN Gulenko. Snow-removing machines and mechanisms (device, operation and repair). - Moscow, "Transport", 1973, second edition, additional and corrected - p. 20-21), which consists from a steel hub mounted on the cantilever part of the drive shaft of the rear wall and six radial blades, three of which are made in width to the full depth of the rotor, and three are shortened in width equal to a third of the depth of the rotor. However, the use of an exhaust rotor also does not allow removing snow drifts in a corridor up to three meters high.

A mounted rotary snow blower is also known, which contains a thrower with radial blades and a rotor with rotary shock blades inclined to the axial line in the form of separate radial axial concave bent in the direction of rotation and mounted in supports in the housing casing with the exhaust window upward above the thrower in the exhaust rotary a guide pipe, a drive device with a kinematic transmission of rotation to the rotor and thrower, (utility model patent No. 47912 of 04/27/2005). The mounted rotary snow blower also does not allow to remove snow drifts in the corridor up to three meters high.

The objective of the claimed utility model is the creation of snow removal equipment that allows punching corridor paths in virgin snow after snow avalanches and snow blockages to evacuate people and vehicles.

To achieve this goal, the mounted snow removal equipment contains a working body made in the form of a feeder-cutter with four blades extending from the center to the periphery and four formed “windows” under the blades. The equipment contains a hopper-filler, made in one housing with a cutter-feeder, while the back wall of the hopper-filler serves as a working body in the form of a cutter-feeder and is integral with the blades and the "windows" under them. Four longitudinal slots are made in the filling hopper located around the working area of the filling hopper at the border with the working area of the feeder cutter. To lighten the weight of the entire structure, the back of the filling hopper may have holes that are simultaneously designed to remove excess snow.

The four “windows” under the blades are designed to receive snow removed by the blades of the mill-feeder. Four longitudinal slots (slots) around the working area of the filling hopper at the border with the working area of the storage cutter serve to eject the collected snow in the form of snow dust.

In FIG. 1 is a drawing of the proposed mounted snow removal equipment.

The mounted snow removal equipment contains a feeder mill 1, four blades 2 installed at an angle of attack of about 10 degrees, four “windows” 3 located under the blades, hopper-filler 4, four longitudinal slots 5 located around the circumference of the working area of the hopper-filler. The milling cutter with blades serves as a snow picker and can be made, for example, of steel. The filling hopper serves as a snow cleaner and can also be made of steel. The milling cutter is mounted on a motor shaft with a power of 30 kW or more (not shown in the drawing).

Mounted snow removal equipment works as follows. The snow removed by the milling cutter - by the feeder 1 through the "windows" 3 located under the blades 2 enters the storage hopper 4, which rotates together with the milling cutter-feeder 1. The rotation speed can be from 400 rpm. up to 2000 rpm Through the longitudinal openings 5 located in the working area of the filling hopper 4, snow dust is emitted into the atmosphere, thereby freeing the road from snow blockages and making a corridor for the passage of manpower and equipment.

The use of mounted snow removal equipment will allow to evacuate people and vehicles from snow captivity as soon as possible.
