SU1491357A1 - Double-track disk orchard harrow - Google Patents

Abstract

This invention relates to an agricultural technique. The purpose of the invention is to improve the quality of tillage by maximizing the overlap of disc tracks with a change in the angle of attack. The device comprises a frame 1 on which disks 5 rotating on an axis 9 and made with a cutting edge 12 are placed by means of a pivoting bracket 6, a leash 7 and a vertical hinge 13. When preparing a two-track harrow, the disks 5 are set with an offset axis rotation of the next row relative to the axis of rotation of the previous row yes half the distance between adjacent disks in the row. Such placement of the disks allows fixing the center of the furrow of each disk 5 of the next row, midway between the furrows of the disks of the previous row, which ensures maximum overlapping of the tracks of the discs when the angle of attack changes, and consequently, improving the quality of tillage. 4 il.

The value of the invention is not an improvement in the quality of night processing by maximizing the overlapping of single disks as the angle of attack changes.

On fi1. I shows a garden disc two-leg harrow, general view; in fig. 2 view A fng. one; in fig. 3 - profile processed with. w soil known two-track garden harrow; in fig. 4 - the same, the proposed garden disc two-harrow.

(The garden disc of a two-leg harrow contains a frame 1 pivotally connected to a mounted device) device 2 by means of m. T 3, forming an articulated parallelogram between them. A hydraulic device 4, with a HOMonibK), is mounted on the hinged device 2 and one of the tons of 3, which forms with frame 1 and the hinged device 2 П1а) nirnee parallelogram, the frame 1 is printed with disks 5 fixed on the drink, to the side and back to the position symmetrical to the tractor.

Frame 1 is articulated in two rows with a single pitch / pitch with a shift of 0.5 / relative to each other, and vertical hinges at the front of the pivot brackets () (Enzhrug b axis) in the upper part of the frame) Pi1e on |) bit 7, and at the bottom - iodpishnikovy knot 8, on the axis 9 of which fixed disks 5.

side, by moving t g 10 and 1 I, the angles of attack of the previous row of disks are set to 20 °, the subsequent to 30 °. The removal of the harrow to the side is provided by the lateral component of the force due to the difference in the angles of attack of the disks of the previous and subsequent rows, and is carried out back by means of a hydraulic cylinder 4.

When moving the harrow forward from that the disks 5 of the previous and subsequent rows are located with a certain pin and are displaced relative to each other by 0.5 /, and the center of the disc groove coincides with the b axis of rotation of the swivel arms 6, since the b axis of rotation is rotatable. x brackets 6 passes vertically through the axis 9 of rotation of the disk 5 and its cutting edge 12, thus the center of the groove of each disk 5 of the next row, regardless of the angle of attack of the disks, is strictly in the middle between the grooves of the disks 5 of the previous row, ensuring thereby with abilnoe the width and depth of the soil, and backwash cropping crop residues.
