RU2454845C2 - Tillage outfit - Google Patents

Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, in particular, to gravitational farming and may be used for speed treatment of soil. An outfit comprises rotary working propulsive agents and a platform with a power converter. The platform is arranged as self-propelled with front and rear swinging supports. The platform is installed in front of rotary working propulsive agents or behind them or between them. The platform may be equipped with a device to raise supports closer to working propulsive agents.

EFFECT: structural design will make it possible to ensure outfit operation in loose soil due to the possibility to adjust value of adhesion depending on soil hardness and also to ensure solid surface and piercing deep treatment of soil at high speeds.

Description

The invention relates to agriculture, and more specifically to gravitational agriculture, and can be used for high-speed tillage.

A device is known (German patent No. 840023, class 45a, group 12 dated May 26, 1952) for tillage using rotary working bodies-movers made in the form of disks (see Medvedev V.I. Power engineering of machine units with working bodies-movers Cheboksary: Chuvash Book Publishing House. 1972, p. 45).

To reduce the energy consumption of tools with rotating shafts on which discs or parts thereof are mounted, they process the soil and at the same time they are the unit's drivers in the field.

The disadvantage of this device is the loss of performance when working on soft, loose soils and not deep processing.

Known tillage unit (French patent No. 650141, class 45 a 28, from 09/09/1927), the contact of which with the soil is carried out exclusively through its working bodies.

Their rotational movement simultaneously provides tillage, the unit moves forward and maintains its direction of movement. That is, tillage is carried out using rotary working bodies-movers (see Medvedev V.I. Power engineering of machine units with working bodies-movers. Cheboksary: Chuvash Book Publishing House. 1972, p. 46).

The disadvantage of this device, adopted as a prototype, is also the loss of performance when working on soft, loose soils, it is not continuous and not deep processing.

The invention is aimed at ensuring the health of the unit on soils of different hardness and deep processing, while the soil should be processed in one pass without passes.

For this, in a tillage unit containing a platform with a power converter and at least a pair of rotary working bodies-propulsors, according to this statement, the platform is self-propelled with front and rear rolling bearings, and the rotary working bodies-propulsors are located V-shaped behind it, transverse to the direction of movement.

The rotary working bodies-movers can be made in the form of echeloned spherical disks, and an additional rotating support roller can be installed behind them.

When working on loose soils, i.e. when slipping in the soil of the working bodies-movers, the necessary movement of the unit provides a self-propelled platform.

To increase the adhesion of disks to the soil, i.e. to ensure operability on harder soils, the platform can be equipped with a device for lifting its rear rolling bearings.

Deep loosening and piercing of the sole sole can carry out the bits installed in front of the platform.

They can also be additional rotational working bodies-movers.

The soil cultivating unit may have a device for lifting the front rolling bearings of the platform. Then the unit rests on the rotary working bodies-movers and does not tamp the soil.

To reduce energy consumption and ensure the most optimal operating mode, the speed of movement of the unit should be maintained equal to the peripheral speed of the rotary working bodies-propulsors. That is, slippage of the working bodies-movers should be excluded, which is ensured by the synchronization of control.

In the future, the proposed technical solution is illustrated by a specific implementation with reference to the figures, in which:

- figure 1 shows a section of the unit along its movement and a top view;

- figure 2 schematically shows a section of the unit along its movement with chisels and platform lifting devices.

The soil cultivating unit (see Fig. 1 and Fig. 2) includes a pair of rotary working bodies-propulsors 1, 2 and a platform 3 with a power converter, for example, in the form of a hydrostation driven by an internal combustion engine (not shown in the figures). Platform 3 is self-propelled with rear 4 and front 5 rolling bearings.

The rotary working bodies-propulsors 1, 2 are located behind the platform in a V-shape, oriented transversely to the direction of movement (see Fig. 1) and made in the form of echeloned spherical disks 6, behind which a roller 7 is mounted.

Spherical disks 6 are mounted on two shafts (not shown in the figures), which are connected at one end to the GST gearbox (hydrostatic transmission) 8, and the other is freely fixed in the supports on the frame of the working propulsors. The frame and platform 3 are connected by a hydraulic cylinder 9, which carries out the lifting of the rear rolling bearings 4.

In front of the platform 3, bits 10 are mounted on their own shaft, which is also connected to the hydrostatic transmission at one end and fixed to the support with the other. The frame of the bits 10 and the platform 3 are interconnected by a hydraulic cylinder 11, which carries out the rise of the front bearings 5.

Tillage unit works as follows: during rotation of the working bodies of the propulsors 1, 2, made in the form of spherical disks 6, they are buried in the soil. In this case, the soil is processed and at the same time the unit moves in the direction of its movement.

When working on loose soils, i.e. when slipping in the soil of the working bodies of the propulsors 1, 2, the necessary movement of the unit provides a self-propelled platform 3.

To increase the adhesion of the disks 6 to the soil, i.e. to ensure operability on harder soils, the rear supports 4 are raised by the hydraulic cylinder 9, and the platform 3 moves on the front supports 5. This allows you to increase the adhesion of the disks 6 to the treated soil.

Deep loosening and piercing of the sole sole perform bits 10 installed in front of the platform and driven into rotation from its own GTS.

To reduce the pressure on the soil, the hydraulic cylinder 11 raises the rolling bearings 5, then the unit rests on the rotary working bodies, propulsors 1, 2 and bits 10 and does not tamp the soil.

To reduce energy consumption and ensure the most optimal operating mode, the speed of movement of the unit should be maintained equal to the peripheral speed of the rotary working bodies-propulsors 1, 2 and bits 10.

In contrast to the known analogues and prototype, the inventive device provides work on loose soils, it became possible to control the amount of adhesion depending on the hardness of the soil. Provided continuous surface and puncturing targeted deep tillage at the lowest consumption of fuels and lubricants.

This technical solution allows soil treatment in accordance with agricultural requirements at high speeds and does not tamper the fertile soil layer.
