Abstract

FIELD: transport.

SUBSTANCE: method is implemented by means of grouser interaction with soil in adjacent row of row spacing. The device contains axle fixed into wheel rim disc, pillar, grouser. The axle is divided into two parts which are interconnected using bushing and fixed to axles using bolts equally spaced along the length of blind holes. On the working surface of grouser two rows with three through holes in each are evenly drilled.

EFFECT: improvement of functional qualities of propeller, increase in range of agricultural works in row spacing conditions.

Description

The invention relates to vehicles, in particular to devices that increase the traction and coupling properties of the mover of an agricultural unit in row spacing conditions.

There is a method of increasing the towing properties of a vehicle propulsion device, for example, a.s. USSR No. 745762, B60B 15/48. 1980. To implement this method, a rotary-screw propeller is used as an addition to the wheel. When changing the position of the lever with the help of a hydraulic drive, one of the movers is extended while the second mover is being cleaned. Depending on the bearing capacity of the supporting surface, a machine with this type of propulsion device moves only on wheels, together on wheels and rotors, and only on rotors. The method is ineffective in soils with low bearing capacity, leads to the destruction of the structure of the upper soil layer and increased erosion processes.

A disadvantage of the known devices is the high cost, the mass of the mover, the complexity of the design, the low suitability of using a rotor-screw mover on agricultural land.

The closest solution to the technical nature and the achieved effect is a way to increase the traction and coupling properties of the wheel propulsion, including the use of additional supports and by introducing them in closed conditions into a denser subsoil layer of the soil, and its subsequent disclosure, increasing its contact area and reducing tire pressure wheel mover on the upper layers of the soil (patent for the invention of the Russian Federation No. 2349460).

A disadvantage of the known method and device is that these devices do not allow the wheeled agricultural unit to work in row spacing conditions.

The aim of the invention is to increase the functional qualities of the mover, increasing the range of agricultural work in row spacing.

The goal in the claimed method of increasing the traction and coupling properties of the mover is achieved by the fact that the implementation of the functional qualities of the mover is carried out due to the interaction of the hook with the soil in the adjacent row of row spacings.

Figure 1 shows a removable anti-skid device - the main view, figure 2 is a side view.

The device consists of the axis of the first part 1, which is attached to the disk of the rim of the wheel 2 due to the nuts 3. The sleeve of the rack 5 is welded to the axis of the second part 4, the column 6 slides along it, along which blind holes 7 are uniformly drilled along the length, which allows it to extend the necessary length due to the fixing bolt 8. In order to change the protective zone in the row-spacings and reduce injury to the plants, the hook 9 has two rows of three holes 10 and is attached to the bottom of the rack 6 due to bolt connections 11. In order to allow the unit to work in the conditions of the row spacing p zlichnoy width axis of the first 1 4 and second parts connected by a hub shaft 12, fixing by means of bolts 13. To adjust the length of the axes are equally spaced blind holes 14. In order to eliminate the rotation device relative to the wheel axle 1 abutments 15 are screwed to the regulators 16.

The principle of operation is as follows. Using nuts 3 to the wheel rim disk 2, fix the axis of the first part 1. By screwing the stops 15 into the axis 1, with the regulators 16 we obtain a perpendicular arrangement of the device relative to the wheel rim disk 2. At the other end of the axis 1, we fix 13 with one end through the holes 14 to the necessary the length of the sleeve axis 12, and on the other end we fix the second part of the axis 4 with the sleeve of the rack 5, into which we place the rack 6 and fasten with a bolt 8. Depending on the size of the protective zone of the row-spacing, we attach the hook 9, b horizontally or vertically screw connection 11 (shown by the dashed line of figure 1).

When the wheel is rolling on waterlogged soils, the rack 6 is set to the maximum value. With increasing soil hardness, the height of the rack 6, due to the bolted connection 8, is reduced. When the unit exits onto a paved road (asphalt, concrete), the hooks 9 are set to a minimum height, as a result of which interaction with the road does not occur.

The proposed method of increasing the traction and hitching properties of the wheel mover allows the wheel unit to work in row-spacing conditions and increase the range of agricultural work.
