Abstract

FIELD: agriculture.

SUBSTANCE: harrow hoeing plough consists of central frame with lengthwise and transverse bars and disks. Equipped with hydraulic drive of transfer from working to transport position and back. Central frame resting on the rotary transport wheels and configured to connect the ladle on both sides comprises beams with discs. Disk racks on beams are installed with possibility of rotation by means of hinged-rack mechanism. Beams are fixed with the possibility of changing the installation angle relative to the direction of movement for readjustment to the mode of the double-action harrowing or the single-action hoeing.

EFFECT: enabling possibility of process control depending on operating conditions and expansion of functional capabilities.

Description

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

As a prototype, a disk harrow was selected, consisting of a central frame and side frames pivotally attached to it, having longitudinal and transverse bars and disk batteries with disks, and a hydraulic actuator for transferring the side frames from the worker to the transport position and vice versa (Utility Model Patent No. 27981, RU, IPC А01В 21/08, published on March 10, 2010, bull. No. 7).

The disadvantage of the prototype is the inability to use the installation of the required technological parameters of the working bodies, depending on the working conditions.

The technical task of the invention is to provide the ability to control the technological process of the harrow depending on the working conditions and expand the functionality by changing to two-track harrowing or single-track peeling.

The technical result is ensured by the fact that the central frame, supported by swivel transport wheels and made with the possibility of attaching a grip on both sides, contains beams with disks, moreover, the rack of disks on the beams are mounted with the possibility of rotation by means of a hinged-rack mechanism, and the beams are fixed with the possibility of change angle of installation relative to the direction of movement for readjustment in the two-track harrowing mode or single-track peeling.

In FIG. 1 shows a top view in a two-track harrowing mode; in FIG. 2 - single-track peeling mode.

The tiller harrow consists of a central frame 1, which is supported by transport wheels 2. The snitch 3 has the possibility of joining the central frame 1 from two sides. The wheels 2 are connected to the central frame 1 by means of a turntable 4 equipped with a stopper 5. The stands 6 of the wheels 2 are equipped with a hydraulic cylinder 7 for transferring to the transport or working position. Beams 8 with disks 9 are mounted on the central frame 1. Racks 10 of disks 9 on beams 8 are mounted with the possibility of rotation by means of hinged-rack mechanisms 11 with a regulator 12 of the angle of attack of the disks 9. The beams 8 are fixed with the possibility of changing the installation angle relative to the direction of movement for readjustment to double-track harrowing or single-track peeling. The middle of the beams 3 are fixed symmetrically in the center of the Central frame 1 by means of vertical hinges 13, and the ends of the beams - in the desired position rigidly on the Central frame 1. The snitsa 3 is equipped with a screw tie 14.

Harrow tiller works as follows. The tillering harrow can be used for surface tillage in the two-track harrowing mode or single-track tilling.

In the two-track harrowing mode, the scythe 3 is mounted on the central frame 1 of the tiller harrow (Fig. 1) so that the beams 8 with discs 9 are located at an angle of 90 degrees to the direction of movement (the beams 8 are parallel) or at a certain angle relative to the longitudinal axis of the unit ( V-shaped) to change the working width and distance along the track of the discs, and the wheels in the direction of travel. When working on the field, the wheels 2 are lifted by means of the hydraulic cylinder 7. When moving, the disks 9 under the influence of the mass penetrate into the soil and rotate. The cutting edge of the discs 9 cut the soil layer, crumble it, mix the crop residues and weed seeds with the soil and move to the side. The rear disks 9 in the same way return the soil layer to its place. The required values of the angle of attack of the disks 9 for harrowing are set by means of the regulator 12 and the hinge-rack mechanisms 11. By turning the beams 8 relative to the hinges 13 and fixing on the frame 1, the working width and the distance between the tracks of the disks are adjusted in the required position. At the end of the rut, the wheels 2 are lowered by means of the hydraulic cylinder 7 and the tiller harrow is raised to the transport position.

To switch to single-track peeling, lower the harrow-tiller to the supporting surface, raise the wheels 2 with hydraulic cylinder 7 to the upper position, release the stopper 5, turn the turntable 4 with wheels 2 by 90 degrees and fix with the stopper 5. Detach the tiller-harrow from the tractor. Remove the gnome 3 and rearrange to the position for the single-track peeling mode (Fig. 2). Rearrange hydraulic piping and identification marks. In the single-peeling mode, the beams 8 with disks 9 are V-shaped relative to the longitudinal axis of the unit. When peeling the wheels 2 through the hydraulic cylinder 7 are torn off the surface of the soil. When moving disks 9 under the action of the mass penetrate into the soil and rotate. The cutting edge of the discs 9 cut the soil layer, crumble it, mix the crop residues and weed seeds with the soil. The required values of the angle of attack of the disks 9 for peeling are set by means of the regulator 12. By turning the beams 8 relative to the hinges 13 and fixing on the frame 1, the working width and the distance between the tracks of the disks are adjusted in the required position.

The values of the angle of attack of the disks 9 and the position of the beams 8 are set depending on the properties of the soil, traction capabilities of the tractor and the required quality of surface tillage. The uniformity of the depth of travel of the front and rear discs 9 is regulated by a screw tie 14 on the grommet 3.

The use of the proposed tiller harrow provides the ability to control the technological process depending on the working conditions and expand the functionality by changing to two-track harrowing or single-track peeling.
