Description

The utility model relates to the field of municipal equipment and can be used as attachments for removing snow, snow slush, etc. snow formations in winter from the surface of roadside and house-side pockets intended for parking lots. It is known that in the winter period of time they clean up freshly fallen snow from sidewalks and carriageways. But the removal of freshly fallen snow from the territory of roadside and adjoining pockets by a mechanical method is usually not carried out due to the relatively small size of the latter, i.e. runways less than 15 meters in size (see GOST 33062-2014 Automobile roads for general use. Requirements for the placement of road and roadside service facilities (entered into force on 01.12.2015).

Known device for cleaning freshly fallen snow from a hard surface [1]. It is a means for sweeping sidewalks, containing a motor installed on the base, kinematically connected with a brush and an endless belt for moving snow into a collection, while the brush is made with the possibility of complex movement due to the presence of two wings, one of which is attached to the brush and has a crank , while the axis of rotation of this link and the crank are located on another link. In this case, the endless belt is made with recesses and a bevel facing the brush and is installed on the sidewalk. The disadvantage of the known device is the need to install an endless brush on the step of the sidewalk, since the entrance pockets in accordance with the above GOST do not have steps and, therefore, the use of the known device in them for cleaning the surface of the entrance pockets from freshly fallen snow and snow slush is not possible.

The closest in technical essence and the achieved result to the proposed device is a snow removal device, which is a mounted cylindrical pile sweeping brush installed on the MTZ 82 tractor [2]. The prototype device is made on a frame with the possibility of installation on the rear overhang of the MTZ-82 tractor and is equipped with a hydraulic motor coupled with a cylindrical pile sweeping brush. The latter, like the lifting and lowering hydraulic cylinders, is connected by means of hydraulic hoses to the hydraulic system of the MTZ-82 tractor through quick-release hydraulic couplings. The frame of the known prototype device comprises a support wheel positioned on the frame behind the mentioned cylindrical nap sweeping brush.

The disadvantage of the prototype snowblower is that the MTZ-82 tractor is capable (due to the presence of a curb and the location of a cylindrical pile sweeping brush behind the tactor) to remove fresh snow from not the entire surface of the roadside and house adjoining pockets, since they are driven from the rear the course of the MTZ-82 tractor, and therefore the support wheel on the frame will be a limiter that distributes the distance between the cylindrical nap sweeping brush (more precisely, the spot of its contact with the surface) and the curb itself to a distance of at least 1.1 m. In addition, delivery of the device -the prototype to the cleaning zone is carried out by the reverse of the MTZ-82 tractor, which also does not contribute to its uniform positioning in the harvesting zone and leads to a deliberate narrowing of the swept-up snow width by the tractor driver to reliably eliminate gaps between the snow-cleared surface strips.

The task to be solved by the creation of a real technical solution,

Consists in the creation of communal and technical means that provide high-quality and fast mechanized cleaning of the surface of road and house entrance pockets, mainly for parking.

The technical result expected from the use of the proposed device consists in increasing the area of cleaning the surface of the drive-in roadside and house side pockets from freshly fallen snow.

The claimed technical result is achieved in that the front winter sweeping brush on the UNIMOG tractor is characterized by a frame formed by one part, positioned in the vertical plane from the first, second, third and fourth arms connected by the ends hinged in the form of a parallelogram, and the second part, positioned in the horizontal plane , by a rigid connection of the arms that form a rectangle, the interaction of both parts of the frame is carried out by means of a pivot link equipped with a swing cylinder, made with the possibility of mounting on the front overhang of the UNIMOG tractor with the first and third vertical frame arms, a lanyard connecting the first and second horizontal frame arms, two parking supports , fastened to the supporting casing, an adjusting rack connected at one end to the second horizontal arm of the frame, and by the second end connected to the supporting casing, by the frame slope connected at one end at the top with the second vertical arm of the frame, and by the second end ohm connected to the first horizontal arm of the frame, support wheels installed under the bearing casing behind the cylindrical nap sweeping brush, a hydraulic motor coupled to the cylindrical sweeping brush by means of an axis placed on two support nodes in the horizontal part of the frame, two fixing chains that space the first horizontal arm of the frame with the second horizontal arm of the frame, a lifting-lowering cylinder connected to the first horizontal arm of the frame and fixed on the second horizontal arm of the frame, brought out towards the rear overhang of the UNIMOG tractor by hydraulic hoses equipped with hydraulic connectors, while the hydraulic hoses are connected to the hydraulic motor and hydraulic cylinders.

The front winter sweeping brush for the UNIMOG tractor is also characterized by the fact that the hydraulic connectors are quick-release.

EXAMPLE.

The work of the proposed front winter sweeping brush on the UNIMOG tractor is as follows. To be cleaned from freshly fallen snow (the measured thickness of the cover was 14 × 10 ^-2 m), the surface of the house entrance pocket (intended for parking a passenger car with dimensions of 8.2 × 4 m.

Upon arrival at the cleaning area, the device is transferred from the transport position to the working position, i.e. device by operating the lifting-lowering hydraulic cylinder 10 (Fig. 2), controlled by the operator by the joystick of the MERCEDES UNIMOG console from the cab of the UNIMOG tractor 1 (Fig. 1) thanks to the hydraulic couplings 16 (Fig. 3) and hydraulic hoses 17 ( Fig. 3) is positioned on the support wheels 7 (Fig. 2), while preventing contact of the parking supports 6 (Fig. 2) with the hard surface of the coating of the adjoining drive pocket. Thus, a cylindrical pile sweeping brush 2 (Fig. 1 and Fig. 2) (the pile diameter is 600 mm) forms a contact patch with the snow-covered surface (about 0.012 m ² ). Lanyard 5 (Fig. 2) provides a rigid connection with the second horizontal arm of the frame 3.6 (Fig. 3) and thereby maintaining the reproducibility of the size of the specified spot when removing snow.

The direction of movement of the UNIMOG tractor is set by the driver forward with a protective shield 15 (Fig. 3) at an angle of approximately 90 ° to the side of the cleaned house drive-in pocket connected to the roadway and the driver starts the hydraulic motor (the rotation speed of which is set at 300 rpm).

By directing the movement of the UNIMOG tractor into the depth of the cleaned house drive-in pocket (i.e. moving forward to the stop with a curb on the opposite side), the driver sweeps freshly fallen snow by means of a rotating front winter sweeping brush 2 (Fig. 1) of the claimed device. Then the driver brings the UNIMOG tractor to the starting position, shifts (visually orienting himself) to the area of the adjoining pocket that has not been swept away from the snow, and repeats the previous action until the above-mentioned surface is removed (swept) from the snow. The resulting snow estimate is subsequently removed from the surface of the roadway by other means of municipal cleaning equipment, in particular, intended for cleaning roads and streets from snow (for example, KDM BUCHER CR, manufactured by MERCATOR HOLDING, Russia).

Table 1 presents the data of comparative tests of the claimed device and the prototype device.

Based on the data of comparative tests of the proposed device and the prototype device, which are presented in Table No. 1, it can be argued that the claimed technical result has been achieved.
