Description

The invention relates to means for cleaning streets and roads, namely to trailed snow blowers.

State of the art

A device for a snow blower is known, which, using special holes in the car frame, is attached to it from behind. This device consists of a drawbar, on the one hand through a swivel attached to the frame of the car, on the other hand, to the working part of the snow blower. The hydraulic cylinder raises or lowers the working part of the snow blower using a traction system (US Patent 5046271, CL E01H 5/06, 1991).

One of the disadvantages of this device is that when hitting an obstacle in the form of ice, curbs, a small column, etc. there is a chance of damage to the snow blower with the hydraulic cylinder and the car. The next disadvantage of this snow blower device is that this device can only be used on a specific car, in which the frame is modified, special fasteners are installed, and a hydraulic system for the hydraulic cylinder is installed.

At the presented device, the blade is installed at right angles to the drawbar of the car, which eliminates the disruption of a stream of snow outside the carriageway. A snow wall will form along the roadsides, which will interfere with further snow utilization.

A device of a snow blower is known, the construction of which is assembled from 3 wooden shields. With the help of a special lever, the rear part of the snow blower can be lifted when snow overflow occurs (USA Patent 2552426, CL 172/393; 37/219; 37/271, 1951).

The disadvantage of this design is the low productivity, because, in addition to the driver who drives the vehicle pulling this device, an additional human operator is required to clear the snow, who stands behind the snow blower and controls the process.

The closest device to this invention, taken as a prototype, is the design of the snow blower, which is a wooden frame in the form of a triangle, on one side of which a blade is installed. Using a special lever and lock, the blade is adjustable in a vertical plane. Due to the adjustments, this design prevents the accumulation of snow in front of the blade (USA Patent 1704016, CL 37/268; 37/271; 37/279, 1929).

The disadvantage of this device is the difficulty in manufacturing the structure due to the large number of small parts, the difficulty in attaching the blade, the insufficient durability of the structure, most of the elements of which are made of wood, as well as the fact that this snow blower will unfold during movement due to the ski They do not have ribs, with the exception of the front steering shoe, but are made flat.

The next disadvantage of this snowplow is that it requires an operator or an additional load.

SUMMARY OF THE INVENTION

One of the tasks set before the authors for the solution of which the proposed technical solution is directed is the strength of the structure and the increase in the service life of the product. The technical result is achieved due to the fact that all the elements of this invention are made of steel.

The next task is to provide the snow blower with a rectilinear movement so that when clearing the snow there is no reversal of the rear part of the snow blower. The technical result is achieved due to steel corners with pointed front edges, which are runners. While the snow blower is moving, the corner shelves are immersed in snow and prevent the structure from turning when clearing the snow.

The next task is ease of manufacture, low cost of the product. The technical result is achieved due to the fact that a small number of parts is used, and the assembly process does not take much time, is simple. In the manufacture of special equipment is not required. Another objective is the ease of attachment of the blade. The technical result is achieved by installing dumps on top of a steel sheet. This is new. With this mounting option, it is enough to drill several holes in the steel sheet, and fix the blade with bolts or in another way. The next task is to throw snow off the road. The technical result is achieved due to the presence of two dumps, right and left, mounted on top of a steel sheet. The left blade is installed in front of the universal snow thrower, parallel to the front beveled side of the steel sheet indented from the edge. The protruding part of the steel sheet is a knife. The right blade is installed end-to-end and at an adjustable angle to the left blade. When the universal snow blower moves, snow is thrown outside the surface being cleaned. Another technical result is achieved due to the fact that the right side of the right blade hangs above the ground to the height of the corner (runner) and goes beyond it.

The next task is the versatility of the tractor. The technical result is achieved due to rods that are mounted on articulated joints and can be of various lengths depending on the vehicle. Due to this, the proposed invention can be pulled by almost any tractor: car, truck, bus, snowmobile, ATV, etc.

The next task is to protect the structure in the event of a collision with an obstacle. The technical result is achieved due to the fact that the rod system is mounted on articulated joints and provides freedom of movement of the universal snow thrower in any plane. When hitting obstacles in the form of ice, snowdrift, curbstone, a small column, this design goes around obstacles. In this case, the steel corners used to stabilize the invention, in this case, do not impede the change in the trajectory of the universal snow thrower. Thus, the universal snow blower and tractor do not get damaged.

The next task is to increase labor productivity. The technical result is achieved due to the fact that the presented invention is designed in such a way that during operation the snow does not accumulate on the structural elements. There is no need to waste time cleaning the structure. The technical result is also achieved due to the fact that when cleaning snow requires only one person, the driver of the tractor.

List of drawings

Figure 1 shows a universal snow blower front view, figure 2 is the same, a top view, figure 3 is the same, rear view, figure 4 is the same side view.

The universal snow blower contains a horizontally lying steel sheet in the form of a rectangular trapezoid 1, while the beveled side of the steel sheet is in front of the snow blower. The slide 2, 3, made in the form of two corners with a pointed front part and installed under the steel sheet 1 in parallel and along the edges of the bases of a rectangular trapezoid. Left blade 4 mounted in front of the structure parallel to the beveled side of the steel sheet 1 indented from the edge. The protruding part of the steel sheet 1 is a knife 12. The right blade 5, installed end-to-end and at an adjustable (due to the adjustment holes 14 in the steel sheet 1) angle to the left blade 4. The right side of the right blade 5 extends beyond the steel sheet 1 and hangs over the cleaned surface to the height of the corner (runner) 3, articulated joints of rods 6, 7, 8, rods 9, 10, 11, articulated towing device 13.

Universal snow blower works as follows.

The design is attached to the rear of the vehicle using a hinged towing device 13. During the movement of the vehicle, the knife 12 partially cuts off the snow and throws it onto the dumps 4 and 5. Due to the fact that the dumps 4 and 5 are installed under the adjustable one (due to the adjustment holes 14 in the steel sheet 1) angle, snow during the movement of the universal snow thrower moves along the dumps outside the road. The slide 2, 3, made in the form of two steel corners with pointed front edges, prevent the structure from turning. In the case of a universal snow blower hitting an obstacle in the form of a snowdrift, a curbstone, a small column, ice, due to the rod system 9, 10, 11 at the articulated joints 6, 7, 8, the latter bends around the obstacle. In this case, the tractor and the universal snow blower do not get damaged. In the case of a collision with an obstacle, corners 2, 3, which serve to stabilize the movement of the universal snow thrower, do not interfere with the latter to go around the obstacle.

The thickness, dimensions of all structural elements of the proposed invention may vary depending on the type of vehicle and other factors.

There is a working copy of this invention, which has been tested and is used to remove snow from access roads to garden cooperatives.

Industrial applicability

The invention can be easily made from modern steel materials and can most effectively be used to clean streets and roads. To clear snow globally, the following idea can be used: snow removal points are located in the village and at the entrance / exit from the village. Universal snowplows proposed by the authors are stored there. When a car enters a village in the wintertime at a snow clearing station, a universal snow blower is attached to it for a small fee. The car passes through the entire village and passes the device on the road. Due to the fact that every year there are more and more car owners throughout Russia, it is possible to effectively deal with snow while not spending money on the purchase and maintenance of special road vehicles.
