Abstract

The invention relates to the field of agricultural engineering, namely to wide-spread tillage tools and can be used when translating the latter into the transport position. The purpose of the invention is to expand the technological capabilities by improving the copying of the soil surface with a reduced capture width and improving the reliability of transportation. The wide tillage implement includes a central section 1, lateral 2 and extreme 3 pivotally connected with hydraulic cylinders 4. When exposed to hydraulic cylinders 4 on hinges 8, link 10 through racks 13 lifts the outer sections 3, turning them on hinges 16 relative to side sections 2, and the warming-up links 9 and 10 of the two-unit link are set at an angle of 5-25 °. This arrangement of links 9 and 10 allows the hydraulic cylinders 4 to be freed from the load, thereby leaving them in a floating position and ensuring the mobility of the kinematic chains: the central section 1 — the lateral sections 2 — the internal links of the two-link tg 9 — the hydraulic cylinders 4. 5 Il. € (L

The invention relates to the field of agricultural engineering, namely to wide-spread tillage tools, and can be used when translating the latter into the transport position.

The purpose of the invention is to expand the technological capabilities by improving the copying of the soil surface with a reduced capture width and improving the reliability of transportation.

FIG. 1 shows a wide tillage implement in the working position with full grip width, rear view; in fig. 2 - the same, in the working position with a reduced width; in fig. 3 - the same, in the transport position; in fig. 4 — node I in FIG. 2; in fig. 5 - {node I in FIG. 3

: A wide tillage tillage, the breast contains pivotally connected central 1, lateral 2, extreme 3 sections and a mechanism for changing the working width, which also serves to transfer the implement from the working position to the transport one and back. j The mechanism for changing the width of the grip has hydraulic cylinders 4 installed on the stand 5 of the central section 1. The rods 6 of the hydraulic cylinders 4 are equipped with sector-limited gels 7 and, through flat hinges 8, are bound 9 and 10, hinges 11, connected to the links (racks) 12 and 13, rigidly fixed on the side sections 2 and on the extreme sections 3, respectively. Supports 14 are mounted on the side sections 2.

The side sections 2 are attached to the central 1 by longitudinal horizontal hinges 15, and to the outer sections 3 by the same hinges 16. All sections are equipped with working members 17, and the central and lateral sections have support wheels 18.

The reference support of the sector stops 7 are mounted to the rods 6 at an acute angle a. In the position of reduced grip width, the links and rods 6 constitute an acute angle p, and the links 9 and 10 make an angle Y 5-25 °.

The proposed wide tillage implement works as follows.

During operation with a full working width, the hydrocylinders 4 are in the floating position and sections 1-3, turning on the hinges 15 and 16 relative to each other, copy the soil surface.

When translating the guns from the full width of the grip to the reduced width of the grip, the hydraulic cylinders 4 are turned on. They retract the rods 6, as a result of which the extreme sections 3 are raised through the hinges 8, links 10 and pillars 13

interactions with the supports 14. Then the hydraulic cylinders 4 are turned on and put into a floating position. Extreme sections 3 remain elevated, as their position is fixed by links 9 and 10, which make up an angle of 5-25 ° between them.

With the extreme sections 3 thus fixed, the side sections 2 can be freely rotated on the hinges 16 relative to the central section 1, the copier

0 the soil surface (since the hydraulic cylinders 4 are in a floating position). In this position, the instrument works with a reduced width of the grip.

To translate the gun into the transport position, hydraulic cylinders 4 are included, which, inwardly rods 6 through hinges 8, links 9, hinges 11 and pillars 12, lift up the side sections 2. to the middle of the cannon. The angle of inclination is calculated so that the projections of the center of gravity of the masses raised up the side 2 and extreme 3 sections into the horizontal plane pass between the hinges 15. Thus, in the transport position the sections 2 and 3 raised up hold the locked hydraulic cylinders 4 , but also its own body weight. Moreover, the extreme sections 3 try to push the hinges 8 down through links 10. But this is prevented by the stops 7, which abut against the links 9. The link 9 relative to the flaps of the 6 hydraulic cylinders is located at an acute angle a.

Such an arrangement of the elements of the automatic fixation nodes allows, when transferring the gun from the transport position to

5 operating the full force of the retractable hydraulic cylinders 4 through the rods 6, the hinges 8, the links 9, the hinges 11 and the pillars 12 transmit to the side sections m 2 and lower them to the ground. This eliminates the possibility of rotation of the outer sections 3 relative to the lateral 2, until they fall to the ground and the link 9 does not abut against the supports 14. When the lateral sections 2 are lowered to the ground, the hydraulic cylinders 4 are turned on and transferred to the floating position. In this position, the gun works with a reduced width.

At the same time, the links 9, which abut against the supports 14, relative to the rod 6 of the hydraulic cylinders, are located at an acute angle p. Such an arrangement of the link 9 with respect to the rods 6 allows the included hydraulic cylinders 4, pushing the rods 6 when the gun is moved from the reduced grip position to the full grip width, to lift the links 9 from the supports 14, turning them on the hinges And relative to the racks 12, and through the links 10 and rack 13

in a floating position. The implement works with full grip width.

The proposed technical solution allows wide-spread soil cultivating tools with reduced width to better copy the soil surface. This greatly improves the quality of its processing, since it increases the uniformity of loosening in depth, especially in conditions of troubled relief, and, in addition, increases reliability during transportation.
