RU48690U1 - UNIT SEMI-MOUNTED MULTI-OPERATION SOIL PROCESSING - Google Patents

Abstract

The utility model relates to agricultural semi-mounted units for subsurface tillage during all periods of field work: for winter, spring and deciduous crops, for winter ripples and instead of spring plowing. The utility model determines the technological layout and design of the main working bodies of the unit in order to grind weed vegetation and to exclude clogging conditions of the inter-disk space on the sections of spherical disks. This is achieved by using a section of spherical disks mounted on the front of the unit frame, while the disks are arranged in two rows on individual racks at an angle of 10 ° -12 ° relative to the vertical plane with the possibility of adjusting the angle of attack and the working width of the disks. Two cultivating sections are placed sequentially in the middle part of the frame with a common uniform displacement of the lancet paws along the width of the unit.

Description

The utility model relates to agricultural engineering, in particular to combined tillage machines and can be used for subsurface tillage during all periods of field work.

Known combined tillage aggregates APU-3,5 and APU-6,5, containing a frame, support wheels, disk sections mounted at an angle relative to the longitudinal axis of the frame, lancet paws, spirally slatted rollers. (“Federal Register of Agricultural Machinery.” Catalog. Moscow, Federal State Institution “Rosinformagroteh” 2001).

Each section of these units has a common shaft with spherical disks, and when the unit is operating on lands with weeds or vegetation residues, they are wound onto the section shaft and clogged rows of disks.

Multi-operational AMP-4 units are also known, containing a frame with an attached device, support and transport wheels on a chassis with a hydraulic mechanism, cultivating sections with lancet and chisel-like legs, two disk sections made of paired batteries with curly disks, one of which is installed in the middle , and the other in the back of the frame (Utility Model Patent No. 41229).

The positive operating experience of these units also revealed a significant drawback: when the unit is operating on lands with high humidity and weeds,

clogging of interdisk space on the first (in the direction of travel) disk section.

The purpose of creating a utility model is to change the technological scheme of the arrangement and layout of the working bodies of the unit for grinding weeds and crop residues with their subsequent incorporation into the soil and the exclusion of conditions for clogging the interdisk space on disk sections.

This is achieved by using paired batteries of two disk sections, one of which is made of spherical disks and mounted on the front of the frame, and the other of the curly disks mounted on the rear of the frame.

Each spherical disk of the first section is mounted on an individual rack at an angle to the vertical plane, while each of the two rows of disks of the section has the ability to adjust the angle of attack and the working width of the discs.

The design of the proposed utility model is illustrated by the drawings:

Figure 1 is a General view of the unit (side view and top).

Figure 2 is a section of spherical disks (front and top view).

Figure 3 is a block of a spherical disk (front and side view).

The unit contains a frame 1 with a hitch 2, supporting and transport wheels 3 on the chassis 4 with a hydraulic control mechanism 5.

A disk section 6 of two rows of spherical disks 7 and a disk section 8 of figured disks 9 are installed on the frame. In the middle part of the frame are two cultivating sections 10 with lancet paws 11.

The spherical disk section (FIGS. 2 and 3) consists of a transverse frame 12, on which spherical disk blocks are mounted in two rows, each of which consists of a disk 7, a bearing assembly 13, which is rigidly mounted on the rack 14 with the possibility of rotation in the sleeve 15.

Each row of spherical disks of the section through the connections 16 racks 14 is pivotally connected by a longitudinal rod 17 with a threaded sleeve 18.

During the operation of the unit, spherical discs produce cutting of soil layers, grinding weeds and crop residues. Separate arrangement of disks allows the unit to work on lands with high humidity, while winding weeds on the axis of the disk and clogging the rows of disks are excluded.

The adjustment of the angle of attack and the working width of the spherical discs is made by a threaded sleeve 18.

The depth of tillage is provided by adjusting the position of the lancet paws and supporting transport wheels.

Curly tail section discs grind, level, and compact the soil.
