Abstract

FIELD: agriculture.

SUBSTANCE: flat-cut plough comprises two frames arranged at an angle to each other with left- and right-turning plough bodies, a mouldboard-type tool in the form of a flat-cutting hoe, furrow levelling devices and support wheels. Mouldboard tool is located at the level of support wheels in vertical plane in the centre between rows of left- and right-turning plough bodies. Devices for levelling furrows are made on each frame behind the post of the last plough body and have installed vertical plate with teeth for destruction of lumps, tillage and levelling of furrows.

EFFECT: higher quality of soil treatment.

Description

The invention relates to agricultural engineering and can be used for cultivating soils subject to wind erosion.

There are known tillage implements capable of simultaneously with plowing with the turnover of the layer leaving stubble windbreaks on the surface of the field. The closest to the invention in design is a flat-cutter plough (Author's certificate No. 2040134, class A01B 3/00, 1995), equipped with moldboard-less working bodies, left- and right-turning plough bodies and means for moving soil into the furrow of the last bodies, in the form of plates with mechanisms for fastening to the frame.

The disadvantages of this design include poor quality processing by moldboard-less working bodies due to the fact that they are located behind the last plow bodies and during the formation of the coulisse they shift the soil to its middle part, due to which hummocks and tussocks are formed on the surface. In addition, during the cutting and pushing of the ridges of the plowing by the leveler into the furrows of the last plow bodies, lumps of soil are formed that require additional processing. As a result, the processed surface remains uneven and requires additional rolling.

The purpose of the invention is to improve the quality of soil cultivation.

The goal is achieved by the fact that the moldboard-less working element is located in the middle part of the frame of the flat-cutter plough between the rows of plough bodies in front of the link, and the vertical plates that prevent the walls of the link from crumbling are fixed on the posts of the last plough bodies. The means for moving the soil into the furrows of the last plough bodies and leveling the ridge surface of the plowed areas are equipped with removable blocks in the form of plates with loosening teeth located on the lower part of the leveller.

A flat-cutting plow contains two frames located at an angle to each other with left- and right-turning plow bodies, devices for leveling furrows, a moldboard-less working element made in the form of a flat-cutting paw and located at the level of the support wheels in the vertical plane in the center between the rows of left- and right-turning plow bodies, and devices for leveling furrows are made on each frame behind the stand of the last plow body and have a vertical plate with teeth installed for breaking up clods, loosening and leveling furrows.

Fig. 1 shows a flat-cut plough, top view; Fig. 2 shows the last plough body with a support, left side view; Fig. 3 shows the same, top view; Fig. 4 shows a device for levelling furrows (leveller) with a block of loosening teeth installed.

The flat-cut plow includes a hitch 1, a frame 2, plow bodies 3, support wheels 4, a moldboard-less working element 5, levelers 6, mechanisms for attaching levelers to the frame 7, plow body stands 8, supports 9, and loosening tooth blocks 10.

The flat-cutting plow works as follows.

When the unit moves, the first plow bodies 3 lift the soil layers cut by the ploughshare and turn them over onto the surface of the field in front of the subsequent bodies 3, which dump layers of increased volume into the furrows of the previous bodies. The moldboard-less working element 5 loosens the soil in front of the stubble link. The last plow bodies 3, dumping soil layers, form a link, the walls of which are held from crumbling by supports 9, fixed on the racks of the last plow bodies 8. The furrows of the last plow bodies are filled with soil, raked and moved from the ploughing surface by levelers 6, which simultaneously break up the resulting lumps of soil with blocks of loosening teeth 10.

Thus, when working with a flat-cutter plough, strips remain, processed with the turnover of the layer and alternating with loosened stubble coulisses. During the working process, the surface of the coulisse is not unloaded and remains at the same level with the plowing, which has a smooth surface, without lumps, requiring no additional processing by rolling.

These advantages improve the quality of soil cultivation using the coulisse technology.
