Description

The invention relates to agricultural machinery and can be used for deep loosening of the soil.

Known chisel plow containing a frame with mounted on it inclined racks (catalog of agricultural equipment. - Volume 1. - M .: information technology. 1991. - S.140, R 21.24).

The technical drawback of such plows is a decrease in the quality of soil cultivation due to clogging in fields with poorly harvested or scattered shredded straw or formed blocks.

Also known is a tool containing a frame with racks mounted on it, each of which has a shoe with a laid-out chisel and a pair of cutting wings fixed to the rack ("Subsoiler - slitherez - plane-cutter GS-4M", description of machines of OAO GKZ, www.kultivator.ru )

The technical drawback of the tool with these working bodies is the limited implementation of a number of types of deep cultivation technologies, the low quality of subsurface tillage and the inability to adapt to specific agrolandscape conditions, which limits the functionality of the tool.

A tillage implement is known that contains a frame with inclined pairs of mounted racks fixed on it with right and left knives, while the length of the horizontal components of the projections of the knives on the transverse vertical plane and the height of the bend line of the inclined part of the rack are equal to 1/4 of the inter-pair of working bodies (RU patent No. 2107414 dated 03/27/1998 Tillage implement).

The technical disadvantage of the described analogue is the technological and technological limitations of the processed layer. This drawback is due to the impossibility of regulating the volume of the processed layer without changing the depth of chiseling.

The closest technical solution to the claimed invention is a soil cultivating tool selected as a prototype, such as a PRG, containing a frame with inclined racks mounted on it with an intrasoil bend, each of which has a shoe with a laid-on chisel and a slope towards the furrow cut that loosens a strip of width 30 cm, and on the opposite side (field edge), in the bending zone, a plane-cutting wing with a loosening width of 45 cm is rigidly fixed (http://www.sibagro.com/p_prg.html).

The technical disadvantage of the prototype is the increased traction resistance and technological limitations, since the wings on the side of the field edge work in a blocked environment and it is impossible to change the amount of continuous processing without changing the depth of chiseling.

Technical task: to increase the operational and technological parameters of the implement by reducing traction resistance, increasing productivity and improving the quality of soil cultivation.

Effect: increase operational and technological performance of the MTA.

The specified technical result in the implementation of the invention is achieved by the fact that the tillage tool, consisting of a frame with slanted stands fixed on it, having an intrasoil bend, each of which has a knife, a shoe with a patch bit, a plane-cutting wing fixed in the area of the vertical part of the rack and directed in the opposite direction side of the bend, and the rack has an inclination toward the field edge, while the length of the horizontal component of the projection of the knife on the transverse vertical plane is ¼ and the length of the burn ontalnoy component projection wing blade on the same plane is equal to ½ the distance between the uprights. The plane-cutting wing is fixed with the possibility of movement along the vertical part of the rack. The size of the continuous loosening zone is regulated by changing the mounting height of the plane-cutting wing through the holes along the strut, regardless of the change in the depth of loosening from the bit controlled by the support wheels.

Figure 1 shows a General view of the working body of the tillage implement; figure 2 is a flow chart of loosening the soil with a tillage implement in a transverse profile with (a) lowered and (b) raised plane-cutting wings.

According to the invention, the tillage implement consists of a frame 1, with inclined racks 2 mounted on it, having an intra-soil bend, each of which has a knife 3, a shoe 4 with a patch bit 5, a plane-cutting wing 6 fixed in the area of the vertical part 7 of the rack and directed in the opposite direction of the bend . Moreover, the rack has an inclination toward the field edge, and the horizontal projection of the knife on the transverse vertical plane is equal to ¼ the distance between the racks. The length of the horizontal component of the projection of the wing blade 6 on the transverse vertical plane is ½ of the distance between the uprights. The plane-cutting wing 6 is fixed with the possibility of vertical movement, for example by bolting through the hole 8 in the wing and the hole 9 along the vertical part 7 of the rack.

Tillage tool works as follows.

The technological process of the work of the tillage implement is reduced to loosening the soil with a chisel 5 and a cutting wing 6 of the working body. The depth of tillage from the bit 5 is regulated by the support wheel, and from the cutting wing 6 by moving it along the vertical part of the rack 7, aligning the hole 8 in the wing through the holes 9. The ratio of the lengths of the horizontal components of the projections of the knife and the wing blade on the transverse vertical plane is equal to равно and ½ distance between racks. Taking into account the spread of soil deformation from the bit at an angle: ≈45 ° and from the position of the smallest size, these ratios are determined. The direction of rack bending towards the field edge, and the plane-cutting wing in the opposite direction (from the field edge) is made in order to reduce energy costs for processing, because volumetric loosening is less energy-consuming flat-cutting. Separate adjustment of the depth of cultivation from the bit and the zone of continuous loosening from the paw allows you to optimize the volume of the deformable soil, taking into account the increase in water permeability and creating the optimal structure for the root layer depending on the crop, which ultimately affects the costs and the resulting yield.

Such a constructive implementation of a tillage implement can improve the operational and technological performance of the MTA.
