Abstract

FIELD: agriculture; mechanical engineering.

SUBSTANCE: invention refers to the field of agricultural engineering, in particular to the working tools for basic cultivation. Working tool of the cultivating tool includes the stand (1), the plough share (2), the blade (3), the ripper (4), which is attached to the side of the stand (1) and is adjustable in height. Chisel (5) of the ripper (4) is exposed below and in the middle of the plough share (2) in the transverse-vertical plane. Ripper (4) is attached to the stand (1) through the spacer (6), at which at least two rows of vertical holes (7) are provided. Holes (7) provide for two positions of the chisel (5) in the alignment, relative to the tip and the toe of the plough share (2). In case of the first position, the chisel groove depth (5) relative to the tip of the plough share (2) is not less than half the difference between the width of the plough share (2) and the chisel width (5). In case of the second position, when the chisel (5) is worn with respect to the toe of the share (2), the groove of the chisel (5) with respect to the toe tip (2) is not more than half of this difference.

EFFECT: such a design solution provides for the reduction in operating costs for basic cultivation.

Description

The invention relates to the working bodies for the primary tillage tools and can be used in agriculture.

Known combined plow containing a frame mounted on it with moldboard cultivators and dump bodies of the upper tier (Agricultural machinery: Cat., T. 1 "Equipment for crop production." - M .: FGNU "Rosinformagroteh", 2005. - S. 157).

This arrangement of the working bodies on the plow frame leads to increased clogging with soil blocks and plant residues under certain soil and climatic conditions.

Also known is the working body of the plow, containing mounted on the frame dump body, each of which consists of a rack, ploughshare, blade and field board. For each dump building, below its ploughshare, rippers are installed, rearranged in height (Harlansky V.M., Gorbachev I.V. / Agricultural machines. - M.: KolosS, 2004. - 25 S.).

The technical drawback of the plow with these working bodies is the collapse of the field crop and the increased dimensions of the combined working body in order to reduce backwater plowing, and not symmetrical loosening of the bottom of the open plow-dump plane leads to an increase in the unbalance of the plow in the horizontal plane.

The closest device to the declared working body of a tillage implement is a working body, consisting of a stand, a ploughshare, a blade, a cultivator attached to the side of the stand, rearranged in height, the bit of which is set lower and in the middle of the ploughshare in a transverse vertical plane (RF Patent No. 2502250, dated 12/27/2013).

The technical disadvantage of the plow with these working bodies is the inability to implement the technology of dump processing with subsequent soil deepening without replacing the working body.

Objective: reduce the operating costs of the primary tillage through the use of reconfigurable working bodies.

EFFECT: depending on the soil and climatic conditions, taking into account the crop rotation culture, it is possible to carry out the main tillage technology with loosening deeper than the ploughshare before the formation turnaround or with soil deepening after the turn of the formation.

According to the invention, the working body of the tillage implement consists of a stand, a ploughshare, a blade, a cultivator attached to the side of the stand and rearranged in height, the bit of which is set lower and in the middle of the ploughshare in a transverse vertical plane. The cultivator is attached to the rack through a spacer on which at least two rows of vertical holes are made, ensuring two positions of the bit in the alignment, the first of which is relative to the share of the share, and when deepening the tip of the bit relative to the share of the share, at least half the difference between the share and the bit width. The second is relative to the heel of the share, and when deepening the toe of the bit relative to the heel, no more than this half of the difference.

In FIG. 1 shows a working body of a tillage implement, rear view; in FIG. 2 - working body of a tillage implement, toe of the cultivator bit in the plane of the toe of the share, right view; in FIG. 3 - working body of the tillage implement, toe of the cultivator bit in the plane of the heel of the share, right view.

The working body of the tillage implement contains a stand 1, a ploughshare 2, a blade 3, a cultivator 4 with a chisel 5. A cultivator 4 is attached to the stand through a spacer 6. At least two rows of vertical holes 7 are made on the spacer 6, providing two positions of the chisel 5 in the alignment relative to the toe 8 and heels 9 of the share 2. Moreover, in the first position, the deepening of the toe 10 of the bit 5 relative to the toe 8 of the share 2 is not less than half the difference between the width V _{l of the} share and the width V _{d of the} bit. In the second position when wearing 10 bits 5 relative to the heel 9 of the share 2 - no more than half of this difference.

The working body of the tillage implement operates as follows.

With the location of the toe 10 of the bit 5 of the cultivator 4 in the plane of the toe 8 of the share 2, the technological process of the working body of the tillage implement is reduced to the initial loosening of the soil from the bit 5 of the cultivator 4 with the subsequent rotation of the loosened soil with the blade 3. Deepening of the toe 10 of the bit 5 relative to the toe 8 of the share 2 not 2 less than half the difference between the width _l in the coulter 2 and the bit width in the _d-5 allows to fully loosen the soil the coulter cutting zone 2, which reduces the energy consumption for operation of dump body.

With the location of the toe 10 of the bit 5 of the cultivator 2 in the plane of the heel 9 of the share 2, the technological process of working the working body of the tillage implement is reduced to the initial cutting of the soil with the share of 2 with the subsequent rotation of the blade 3 and then by deepening the bit 5 of the cultivator 4. Deepening the toe of 10 bit 5 relative to the heel 9 of the share 2 no more than half the difference between the width V _{l of the} share 2 and the width V _{d of the} bit 5 allows to exclude loosening of the soil outside the cutting zone of the share 5, which prevents the collapse of the soil wall of the field edge.

Such a constructive implementation of the working body of the tillage implement allows you to configure the work of the tillage implement to the required tillage technology and optimize its traction resistance, which improves the operational and technological performance of the MTA and, accordingly, reduces the operating costs of the main processing.
