Abstract

The invention relates to agricultural machinery. The purpose of the invention is to improve the quality of plowing cotton fields with uneven terrain by improving the uniformity of the depth of processing and the stability of the plow in the direction of movement. SUMMARY OF THE INVENTION: the plow is equipped with a furrow divider in the form of an additional plow body with a plough-dump surface opposite to the main bodies. A plow body is mounted in front of the support wheel 3 and above its supporting surface. 1 s.p., f-ly, 2 ill.

Description

 The invention relates to agricultural machinery, in particular to implements for basic tillage on cotton floors.

Known plow, including a frame with mounted on it housings and a support wheel.

The disadvantages of this plow include the low quality of plowing caused by uneven plowing depth, since under the conditions of the cotton growing zone the plow has uneven terrain before plowing, characterized by the presence of ridges and irrigation furrows. At the same time, the depth of plowing varies to a large extent depending on the rolling position of the support wheel.

The closest in technical essence to the achieved result to the present invention is a plow comprising a frame with housings fixed on it and a pair of swing type support wheels.

The disadvantages of the known plow include the low quality of plowing due to the rolling of the support wheels over an uneven floor surface. In this case, the areas of contact with the soil of the right and left wheels are significantly different from each other, which leads to a skew of the plow.

The purpose of the invention is to improve the quality of plowing cotton fields with uneven terrain by improving the uniformity of the depth of processing and the stability of the plow in the direction of movement

The goal is achieved in that the plow is equipped with a furrow divider in the form of an additional plow body with a plough-dump surface opposite to the main bodies and mounted in front of the support wheel and above its surface support. The width of the furrow cutter is larger than the width of the rim of the support wheel.

Figure 1 shows a plow, rear view; figure 2 is the same, a top view.

The plow includes a frame 1 with the housings 2 fixed to it, the support wheel 2 and the furrow 4. The furrow divider 4, made in the form of a plow body, is installed in front of the support wheel 3. The plow-dump surface of the furrow is opposite to the surfaces of the main housings 2. For the purpose excluding the contact of the lateral surfaces of the support wheel with the soil of the furrow walls, the width of the furrow cutter Bb is greater than the width of the rim b0 of the support wheel by 1 ... 2 cm. Before plowing, the furrow divider was installed aets to a depth equal to the height h of irregularities, and the reference wheel below the coulter blade by an amount e indentation into the soil, i.e. within 1-3 cm, depending on the condition of the soil.

The plow works as follows.

When plowing, the furrower 4 opens the furrow, removing and turning the soil to a depth equal to the height of the ridges — the irregularities of the cotton floor h and the width Be. In this case, the support wheel 3 will roll on a flat surface of the bottom of the furrow opened by the furrower 4. As a result, in any pass of the plow, the wheel 3 will roll in a plane passing at a depth h + e from the top of the ridge. In this way, a uniform depth of tillage with plow bodies is achieved.

The reduction of the reaction force of the soil on the supporting surface of the plow blade of the furrower is achieved by setting the support wheel below it by an amount e equal to the deformation of the soil by the wheel. By making the furrower left-handed, the reaction force of the soil is Rxy. acting on it, creates a moment opposite to the moment of resistance forces of the main buildings. As a result, the field boards of the bodies are unloaded, which will reduce their resistance and improve the stability of the plow. As a result of this, the installation of a boro-knocker does not lead to an increase in the pulling resistance as a whole.

All this improves the quality of plowing cotton fields with uneven terrain.
