Abstract

FIELD: agricultural engineering, in particular, cultivation of soil by means of combined tools.

SUBSTANCE: tillage tool has frame, hitch tongue, carrier-transporting wheels, balance beam, disk batteries, hoes, and roller. Openings provided in upper arm of balance beam, whose point of support is positioned on tillage tool frame, are adapted for altering point of attachment of hydraulic cylinder, and its lower arm is connected to supporting-transporting wheels. Hitch tongue is located forward of disk batteries at altitude N=R+H, where R is radius of disks, m; H is operating depth of disks, m. Roller is pivotally connected to frame at altitude: K=L+M, where L is distance from frame to point of attachment of replaceable hoe, m; M is operating depth of roller, m. Hoes are equipped with three-faced wedge having upper cutting edge made in the form of hyperbole.

EFFECT: improved quality of soil, increased penetration of tillage tool, and uniform depth of working tools.

Description

The invention relates to agricultural machinery, in particular to combined tillage implements.

Known combined tillage implement (A.S. No. 1175374, A 01 B 49/02, 1985), containing a frame, a bale, supporting-transport wheels, rocker arm, disk batteries, legs, roller.

The disadvantages of the known device include the uneven depth of stroke of the working bodies, poor-quality operation of the roller, because the skating rink’s location relative to the surface of the soil is not taken into account, and the paws are poorly buried.

Known tillage implement (A.S. No. 967304, A 01 B 49/02, 1982), containing a frame, a gland, supporting transport wheels, rocker arm, disk batteries, legs, roller, adopted for the prototype.

The disadvantages of the known device include the fact that with such a connection, the deepening of the working bodies into the soil is difficult. There is a periodic deepening of the working bodies, so there is an uneven depth of travel of the paws and discs.

To eliminate these drawbacks, the upper arm of the rocker arm, the fulcrum of which is located on the implement’s frame, has openings for changing the point of attachment of the hydraulic cylinder, and the lower arm is connected to the support-transport wheels, the grip is located in front of the disk batteries at a height

N = R + H,

where R is the radius of the disks, m;

H - the depth of the disks, m;

the legs are equipped with a trihedral wedge with a top cutting edge made in the form of a hyperbola, and the roller is attached to the frame articulated at a height

K = L + M,

where L is the distance from the frame to the attachment point of the replaceable paws, m;

M - the depth of the rink, m

The proposed combination of the rocker arm, support-transport wheels, gnats allows to increase the deepening ability of the guns, to reduce the depth of the path, to reduce the width of the headland at the beginning and end of the headland.

The location of the gnats at a height of H = R + N reduces the time spent and shortens the time for preparing the field for sowing. At H <R + N, the disk batteries will be excessively deep, form a prism of drawing from compacted soil and are characterized by increased traction resistance. At H> R + N, the quality of soil cultivation decreases, an unsatisfactory change in plant residues, and uneven depth of the working bodies are observed.

The implementation of mounted on the paws of a trihedral wedge with the upper cutting edge, made in the form of a hyperbole, allows to improve the deepening ability of the tool, to increase the stability of the working bodies when processing overdried soils.

Joining the roller articulated at a height of K = L + M allows you to produce high-quality tillage without deepening too deeply and without breaking the roller’s contact with the soil, i.e. copying the surface of the soil, simultaneously with compaction, crushing blocks and alignment of the microrelief.

The presence of holes on the upper arm of the rocker arm allows you to change the point of attachment of the hydraulic cylinder, depending on the moisture and hardness of the soil, so that the traction resistance of the implement is minimal.

In Fig.1 shows a tillage implement, side view.

Figure 2 shows a tillage implement, top view.

The tillage implement includes a frame 1, working bodies: disk batteries 2, paws 3, a roller 4, a nut 5, supporting and transport wheels 6, a beam 7, an upper arm 8 of a beam 7, a fulcrum 9 of which is located on the frame 1 of the implement, has openings 10 to change the point of attachment of the hydraulic cylinder, and the lower arm 11 is connected to the supporting transport wheels 6. The gnaw 5 is located in front of the disk batteries 2. The legs 3 are equipped with a trihedral wedge 12 with an upper cutting edge made in the form of a hyperbola. The roller 4 is attached to the frame 1 pivotally.

Tillage tool works as follows.

When the gun moves, the disk batteries 2 are deepened to the required depth, crushed plant residues, crumble the topsoil. At the same time the paws 3 are buried at the same time with the disks, they perform trenchless loosening, ensuring uniform processing depth. Roller 4 copies the surface of the field, while crushing blocks, compacting the soil and leveling the microrelief.

The use of the proposed tillage tool does not have a negative impact on the environment, because allows you to reduce the number of passes in the field, reduce soil compaction and positively affects the reproduction of fertility.
