Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery. The purpose of the invention is to improve ease of operation by providing directional stability when working using a guide groove. The soil tillage device has two drive wheels of different diameters mounted transversely to the direction of movement of the inclined axis. The wheel of larger diameter has starters. Near this wheel, on the side facing the other wheel, is a slightly fixed skid 12. The driving rotary ripper 4 and the plow body 5 behind it are mounted. The ripper 4 is made in the form of a cone-shaped hollow auger and preliminary loosens the soil and dredges plow body 5. The working surface of the ski 12 in the process of moving rests on the furrow wall and parallel to the plane of the field edge of the plow body. 3 il.

WITH

The invention relates to agriculture and can be used for plowing small and medium areas.

There are various tillers with a conventional plow.

However, for a conventional plow, a large pulling force is required and therefore the tillers are stalled. Even on soft tillage, additional weights are attached to the walker. All tillers require continuous control by the handles and the process of working with them is quite tedious.

Various cultivators are known, for example, a motor cultivator, in which the cutter loosens the soil and at the same time there is no ordinary plow behind it.

At the same time, such a unit requires continuous and rather vigorous holding by the handles.

The aim of the invention is to create a device capable of plowing a field, without requiring continuous retention by the handles and increased convenience in operation.

The goal is achieved by using two differently sized interlocked drive wheels and a plate-ski in front of the big wheel.

Figure 1 shows the tillage device, side view; figure 2 is the same, front view; on fig.Z - the same. view from above.

The device contains mounting parts for gearboxes 2 and 3. The cultivator 4 is a hollow cone-shaped auger. It is installed with an inclination of 45 ° in a plane perpendicular to the axis of the driving wheels on

the output shaft of the gearbox 3. The drive wheels 6 are blocked and brought into rotation through the gearbox 2. The diameter of the left wheel is 10% larger than the diameter of the right wheel.

The plow body 5 is installed behind the loosener 4: Plate-ski 10 (folding) is located vertically, in front between the furrow wall and the wheel. Handles 9 are used to control the device.

 The device works as follows.

When the mechanism is in operation, the motor rotates both gears with the aid of a V-belt transmission. Driving wheels 6 provide the device forward. The ripper 4, rotating at a speed of 2-3 rev / s, loosens the soil and, like a gimlet, helps advance. The first two grooves (back and forth) are conducted by directly controlling the plow by the handles. Subsequently, the device installed in the furrow manifests its ability to move along the furrow independently. It happens as follows

Differently sized driving wheels interlocked on one axle tend to turn the unit to the right, but this does not allow the plate-ski sliding along the furrow wall. The larger wheel, moving along the groove with slipping, shifts the whole mechanism to the left thanks to the steeply sloping load plates on the rim. Due to this, the friction of the plate-ski on the ground is reduced.

The use of an electric plow allows you to cultivate any cramped garden plots. When plowing long plots, there is no need to go behind the plow and control it. Way

Claims (1)

loosening the soil allows cultivating arable land in any condition. When using an autonomous welding unit (SAK) with an electric plow, it is possible to cultivate any remote kitchen gardens, as well as city lawns and flower gardens, which, as a rule, cannot be driven onto a tractor. A soil tillage device comprising a frame with two driving wheels, an engine mounted on the frame, control knobs and a driving rotary loosening body mounted behind the wheels and a plow body located behind the last one, characterized in that ensure driving stability when operating using a guide groove, the axis on which the drive wheels are mounted is inclined in the transverse-vertical plane, one Of these wheels has a larger diameter than the other, and is equipped with star chains made in the form of plates, the edges of which are directed back and toward the other wheel, and the driving rotary loosening body is made in the form of a hollow cone-shaped screw mounted on a shaft inclined back in a plane perpendicular to the axis of rotation of the drive wheels, and the device is equipped with a supporting ski located near the larger diameter wheel in front of it from the side facing the longitudinal center line of the cannon, with it supports working surface parallel to the plane hydrochloric skiing field crop plow body. t 10 2 fig 2 3 to 9 4 5 figs
