Description

The technical solution relates to the field of agricultural machinery, in particular to chisel plow rippers.

Known tillage implement with a device for automatically controlling the depth of stroke of the working bodies, containing a frame with a dump plow body mounted on it. The ploughshare on the dump plow body is made with an occipital chamfer on its rear blade part, the surface of which is located at an acute angle to the outer plane of the ploughshare. The angle of the surface of the occipital bevel is greater than the angle of installation of the external surface of the share to the horizontal. The tool is equipped with a copier of the field surface and a moldless body rigidly connected to the frame [A.S. No. 1093273, MKI A 01 B 63/111 published. bull. No. 19 dated 05.23.84].

However, the disadvantage of this tillage implement with a device for automatically regulating the depth of the working bodies is that it is not possible to plow old arable solonetzic soils with a dump plow body equipped with a ploughshare with an occipital chamfer on its rear blade part and a moldless body due to the lack of virgin monolithic solonetz pillars and blocks that were destroyed by previously performed plowing. Lumps of different shapes and sizes formed as a result of the destruction of solonetz pillars prevent the field surface from being copied by a dump plow body.

The closest to the claimed technical solution for the totality of essential features is the chisel plow-ripper ПЧ-4,5, containing a triangular frame with mounted working bodies-rippers, support wheels, a regulator

processing depth, hitch and stand [Khalansky V.M., Gorbachev I.V. Agricultural machinery, - M .: KolosS, 2003, - p. 54-55. ill.].

The disadvantage of this chisel plow ПЧ-4,5 is the unsatisfactory crumbling of the upper fertile layer of old arable solonetzic soils, a large lumpiness after processing conventional soils.

The objective of the proposed technical solution is: to ensure high-quality crumbling of the top layer of cultivated soils, including old arable salt licks.

This object is achieved in that the chisel plow containing a triangular frame, with rippers fixed to it, supporting wheels, a processing depth adjuster, a hitch, is equipped with an additional frame on which disk batteries are pivotally mounted, and cuts in the form of isosceles are made on the blades of round disks triangles with an angle (β) at the apex of not more than 120 °, while the number of cuts is not more than 12, and the sharpening of the blades is made in an arc from the back side, the disk working bodies of the batteries are installed with an angle of attack from 5 to 25 °.

The technical solution is illustrated by drawings, where figure 1 shows a General view of the chisel plow-ripper, right view; figure 2 is a top view; figure 3 - battery disk.

The chisel plow-ripper contains a triangular frame 1 (Fig. 1 and Fig. 2), on which the working bodies-rippers 2 are fixed. In the front part of the implement are mounted: a linkage 3, support wheels 4 with a depth adjustment 5 for soil cultivation. An additional frame 6 and a regulator 7 for setting the angle of attack of the disks 8 are connected to the frame 1. The disk battery 9 is pivotally connected to the additional frame 6. To stabilize the working depth at different soil hardness, the disk batteries are equipped with spring-loaded rods 10. Angle of attack (α) [Fig. 2] batteries set by regulator 7 no more than 25 °. Disc 8 cuts in

in the form of isosceles triangles with an angle (β) at the apex of not more than 120 ° [Fig.3].

The device operates as follows. When the tractor moves across the field, chisel-like cultivators loosen the old arable solonetzic soil, as well as the compacted sole obtained after many years of plowing with plow plows and ploskorez to a depth of 45 cm, which ensures a good water-air regime.

The depth of the working bodies of the cultivators is regulated by the regulator of the depth of processing. Petition of the upper fertile layer and leveling of the field surface are performed by disk batteries mounted on an additional frame, behind the cultivators. Due to the presence of triangular cutouts located around the perimeter of the discs, the latter loosens the soil more efficiently, providing better pinching and cutting of the soil-straw mass without clogging the discs.

At an angle of attack of α> 25 °, the quality of the soil cultivation is significantly reduced: deep furrows and high ridges form on the surface of the cultivated field along the track of each disk, and soil and plant mass is unloaded in front of the disks. At an angle of attack of α <5 °, disc working bodies cannot perform loosening, since at small angles of attack, cutting of the soil with disks is excluded. In these cases, the disc batteries deepen and roll across the field like rollers.

If there are cutouts with an angle β at the apex of not more than 120 ° on the disk blade, the soil and plant (straw) mass is pinched and cut qualitatively: the straw mass is completely cut, soil unloading is eliminated, high-quality loosening is ensured, and traction resistance is reduced.

At β greater than 120 °, qualitative cutting of the soil and plant mass is excluded, it is unloaded before the disks, the crumbling of the soil layer is significantly worsened, the traction resistance of the machine and the consumption of fuels and lubricants are increased.

Using the proposed chisel plow-ripper allows you to perform high-quality crumbling of the upper fertile layer of old arable salt licks as well as loosening the compacted sole formed from prolonged plowing with ploughshares and plane cutters

Crumbling of the upper fertile layer of old arable solonetzic soils with the presence of solonetzic blocks and leveling of the soil surface is performed by disk batteries.

Thanks to the use of disks of this design, the lack of accumulation of soil and plant mass and clogging of disk batteries, the traction resistance of the chisel plow-ripper and the consumption of fuel and lubricants are significantly reduced.
