Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machinery industry. The plough-ripper comprises moldboard housings mounted on the frame, each of which consists of a rack, a plowshares, a mouldboard, a boardless ripper with a chisel, adjustable in height along the rack. The ripper is attached to the rack on its side so it chisel is placed in a transverse-horizontal plane from the edge of the plowshare tip at a distance no more than (0.3…0.5)B, where B is the working width of the housing, and in the longitudinal-horizontal plane at the lowest setting parameters is not more than $$\sqrt{H_2-(\mathrm{0,1...0,2})B^2},$$

where H is the difference between the depths of ripping and soil overturning.

EFFECT: constructive solution enables to improve operational and technological characteristics of the machine-tractor aggregate, and to rip effectively the subsoil horizons.

Description

The invention relates to implements for the main (autumn) tillage and can be used in agriculture.

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

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

The closest device to the declared plow-ripper is a plow containing dump bodies mounted on the frame, each of which consists of a stand, a ploughshare, a blade and a field board, behind each of which a lowering plow is mounted, adjustable in height (Harlansky V.M. ., Gorbachev I.V. / Agricultural Machines. - M.: KolosS, 2006. - 25 S.).

The technical drawback of the plow with these working bodies is the increased dimensions of the combined working body in order to reduce the backwater layer backwater, which limits the functionality of the implement under certain soil and climatic conditions or requires an increase in the longitudinal distance between the hulls, and asymmetric loosening of the bottom by the open hull leads to an increase in the unbalance of the plow in the horizontal plane, which requires high energy costs.

Technical task: expanding the scope of the plow, improving the quality of tillage, reducing specific traction resistance and energy consumption.

Effect: increase the operational and technological indicators of the MTA, the effective cultivation of subsurface horizons.

, где H - разница между глубинами рыхления и оборота пласта.The technical result is achieved by the fact that in the known device containing dump bodies mounted on the frame, each of which consists of a rack, ploughshare, blade, field board and dump cultivator, rearranged in height, which is attached to the rack on the side, so that its bit is located from the edge of the toe share in the transverse-horizontal plane at a distance of no more than (0.3 ... 0.5) B, where B is the width of the grip of the body, and in the longitudinal-horizontal plane no more $$\sqrt{H_2-(\mathrm{0,1\; ...\; 0,2})B^2}$$

where H is the difference between the depths of loosening and turnover of the reservoir.

The invention is illustrated by drawings.

Figure 1 shows the body of the plow-ripper, right side view; figure 2 - body of the plow-ripper, rear view; figure 3 - body plow-ripper, left view.

, где H - разница между глубинами рыхления и оборота пласта.The plow-ripper contains dump bodies mounted on the frame, each of which consists of stand 1, ploughshare 2, blade 3, dump ripper 4 with a chisel 5, rearranged in height along rack 1. The ripper 4 is attached to the stand 1 on its side, so that its bit 5 is located from the edge of the toe of the share 2 in the transverse-horizontal plane at a distance of no more than (0.3 ... 0.5) B, where B is the width of the housing, and in the longitudinally horizontal plane, with the smallest installation parameters, no more $$\sqrt{H_2-(\mathrm{0,1\; ...\; 0,2})B^2}$$

where H is the difference between the depths of loosening and turnover of the reservoir.

The plow-ripper works as follows.

, где H - разница между глубинами рыхления и оборота пласта.The technological process of operation of the plow-ripper is reduced to loosening the soil with a chisel 5 followed by a turnover of the formation with a blade 3. The size of the wrapped formation is regulated by the supporting wheels of the plow. The depth of soil cultivation and, accordingly, the amount of subsoiling loosening is regulated by moving the ripper 4 along the rack 1. The energy of volume loosening from the bit is much less than plane cutting with a ploughshare. Therefore, taking into account the minimum dimension of the implement, the exclusion of clogging and backwater between the bit and the share of the soil, the dimensions between them in width and height are determined, namely, the bit is located from the edge of the share of the share in the transverse-horizontal plane at a distance of no more than (0.3 ... 0, 5) B, where B is the width of the housing, and in the longitudinal horizontal plane no more $$\sqrt{H_2-(\mathrm{0,1\; ...\; 0,2})B^2}$$

where H is the difference between the depths of loosening and turnover of the reservoir.

Such a constructive implementation of the plow-ripper can dramatically reduce traction resistance, metal consumption and energy consumption, increase operational and technological indicators and functionality to adapt to specific soil and climatic conditions.
