Description

The invention relates to agricultural machinery, namely, implements for tillage in the rows of fruit trees.

A tool for cultivating the soil in rows of fruit trees is known, comprising a retractable section with two rows of discs mirrored one after another, including a hydraulically controlled parallelogram mechanism that carries a beam, on which leashes with discs are mounted through vertical hinges, parallel to each other and connected in front of between transverse thrust (see USSR AS A01B 21/00, A01B 63/16, No. 349370, announced 05/03/1971, No. 1649564 / 30-15, published on 09/04/1972, bulletin No. 26).

The disadvantages of such a tool are the high metal consumption of the device and the energy consumption of the process (since disks do not get out of the soil when going around the trunk, which causes additional loads acting on all elements and mechanisms of the section), low quality of the treated soil surface and operational reliability.

There is a known tool for cultivating the soil of tree trunks in intensive gardens, containing a single-row disk battery mounted on a supporting beam, a hydraulic section retraction mechanism, a section rotary mechanism, directional control valves, two probe probes and return springs (see IB Berenstein, Inventors and Rationalizers - gardeners / Reference edition // Simferopol: Tavria, 1989, 208 pp.).

The disadvantage of this device is the design complexity, preventing the synchronization of the mechanism of removal and rotation of the battery, which violates the technological process of tillage and leads to a transverse shift of the soil.

The closest device to the achieved technological and economic effects and technical nature is the BPR-1 disc harrow (see Shevkun V.A. Use of disk tillage tools for soil cultivation in the line of a number of trees / Vestnik FSOI VPO "MGAU named after V.P. Goryachkin" . - M .: MGAU, 2007, Issue 2. P.42-44), containing a disk section mounted on a frame mounted on a tractor hitch through a parallelogram section lateral displacement mechanism located in a horizontal plane and having a control system for it: probe , directional control valve, hydraulic cylinder, and also the stabilizing course of the harrow subframe ski.

The disadvantages of such a tool are the high energy intensity of the process (since disks displaced by the lateral planes toward the row spacing increase the power loads on the structural elements) and the low quality of the work performed (when going around the stump, the disks remove the soil from the row).

The technical solution to the problem provides a reduction in energy intensity, metal consumption, and improvement of the quality of soil treatment.

The task is carried out by the fact that in the proposed tool for processing the near-trunk strip in the rows of perennial plantations, the disk section, mounted with the ability to move across the row, is mounted on a hinged parallelogram mechanism having a control system consisting of a dipstick, a hydraulic valve and a hydraulic cylinder , and one of the vertical levers is made telescopic.

A new constructive proposal is that the vertical arrangement of the parallelogram mechanism allows the disk section to move in a horizontal plane after the discs are completely deepened from the soil, which minimizes the soil raking by the disk section when it is removed from the row.

The essence of the invention is illustrated by the following drawings: where in Fig.1 shows a rear view of the implement for row cultivation of the soil in the orchard, in Fig.2 is a top view.

The soil cultivating tool in the orchard includes a hinge 1, the lower support of which is connected by levers 2 and 3 to the main supporting beam (frame) 4. A rotary column 5 is pivotally attached to the beam, to which a disc working element 6 is mounted, which is an axis mounted on her discs 7. The angle of attack of the discs is regulated by traction 8. To the base of the working body is attached a bracket 9 with a disk valve 10 and a probe 11, providing control of the hydraulic cylinder 12 moving the section in a row and out of a row. To adjust the ratio of the time of preferential movement of the section vertically until it is completely deepened from the soil and the time of the subsequent horizontal movement, one of the levers, for example 2, is made telescopic. The working body 6 is translated into the transport position using the hydraulic cylinder 13. The unit is controlled from the tractor cab. A ski with a knife 14 is installed on the hitch 1, designed to adjust the working depth and stabilize the movement of the harrow along the row during operation.

The device operates as follows. Before starting work, the working body 6 is moved to a horizontal position by the lifting hydraulic cylinder 13, the hydraulic cylinder 12 extends toward the inter-barrel strip, and the processing depth is set by ski 14. The unit begins to move. The disk section loosens the soil and destroys the weeds in the near-trunk zone. When meeting with a tree trunk, the dipstick 11 deviates and rotates the spool of the hydraulic distributor 10. The oil enters the extension cylinder 12, the working element 6 is deepened and after the discs exit the soil completely, it leaves the row in the direction of the tractor. After bypassing the stem, the section is shifted by the reverse stroke of the hydraulic cylinder 12 in a row until it contacts the soil, then its technological deepening takes place.
