RU45065U1 - UNIVERSAL WIDE SOIL PROCESSING UNIT - 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 ripening and instead of spring plowing. The utility model is aimed at creating the optimal technological layout and arrangement of the working bodies of the unit in order to reduce its overall dimensions in length, as well as on the design of individual working bodies of the unit in order to increase their efficiency. This is achieved by the use of sectional angle levelers located between sections of cultivator legs and supporting sections of disk batteries, while battery disks have an S-shaped corrugated edge, and battery sections are equipped with spring rippers. The stability of a given depth of loosening of the soil is provided, if necessary, by additional support of the running wheels with the help of a hydraulic cylinder.

Description

The utility model relates to agricultural semi-mounted units for subsurface tillage during all periods of field work.

Known combined units of the APK-6 and APU-6.5 brands containing a three-section frame, a mechanism for lifting the side frames to a vertical position during transportation, support wheels, lancet paws, support spiral-roller rollers. ("Federal Register of Agricultural Machinery. Catalog. Moscow, Federal State Institution" Rosinformagroteh "2001).

During operation of these units, the support wheels located on the front walls of the central and side frames cannot completely prevent spontaneous deepening of the rippers and the resulting vertical load from the angle of attack of the lancet paws and the mass of the frames is transferred to the supporting spiral-plate rollers, which under the influence of this load are buried in loose soil and clogged with soil, which reduces the efficiency of soil cultivation and the productivity of the unit.

A multioperational unit is also known (Utility Model Patent No. 41229), the design of which provides the possibility of using transport wheels for additional support with excessive deepening of cultivators and disk support sections.

Combination of support wheels with hydraulic control and telescopic attachment coupler

provides stability of the unit on different types of soils.

The disadvantage of this unit is its significant dimensions in length due to the use of two, sequentially located, cultivating sections and two spiral disk sections.

So, for example, the AMP-4 unit of a similar design, commercially available by Medvedev Plant OJSC, has a length of 8,200 mm.

During technological transitions in the field and especially when turning the unit to the next pass, the increased length of the unit complicates the performance of these operations, reduces its maneuverability and requires additional time.

The purpose of creating a utility model is to solve two main technical problems:

determination of the optimal technological layout and arrangement of the working bodies of the unit to ensure high-quality cultivation of the soil, taking into account the reduction in the size of the unit along the length, as well as the design of individual working bodies of the unit in order to increase their efficiency.

The indicated goal of creating a utility model is achieved by the use of sectional angle levelers located between sections of cultivating paws and supporting sections of disk batteries and mounted on S-shaped spring arches with the possibility of moving in a vertical plane, while the disks of the supporting sections have a corrugated S-shaped edge, and the corrugations are symmetrical

relative to the plane of the disk. In addition, the supporting sections of the disk batteries are equipped with spring rippers.

The design of the proposed utility model is illustrated by the presented drawings.

Figure 1 - General view of the unit, side view.

Figure 2 - General view of the unit, a top view.

The unit contains the middle frame 1, side frames 2 and 3, pivotally mounted on the middle frame. On the frames mounted cultivating racks 4 of C-shaped arches with paws 5, supporting wheels 6 with screw traction 7, angle equalizers 8 on S-shaped arcs 9, supporting sections of disk batteries 10 with spring rippers 11.

The hydraulic cylinders 12 provide lifting and lowering of the side frames, and the hydraulic cylinder 13 - raising and lowering the running wheels 14.

A telescopic rod 17 with a device for changing its length is pivotally mounted on a hitch 15 with a support post 16.

The uncoupled unit rests on the ground with transport wheels and a support stand. During operation, the unit in one pass performs the following operations:

- loosens the soil to a predetermined depth;

- cuts and grinds weeds;

- aligns the surface of the field;

- grinds and compacts the soil;

- loosens the surface soil layer.

Adjusting the depth of soil cultivation is carried out by adjusting the support wheels and the length of the telescopic traction.

During operation of the unit on light or wet soil, the specified loosening depth is additionally stabilized by the support of the running wheels with the help of a hydraulic cylinder.

The efficiency of soil grinding by sections of disk batteries is determined by the presence of sectional angle equalizers that are mounted on spring arches and have the ability, for example, when meeting an obstacle, to lift, and after passing an obstacle - to return to their original position.

Spring cultivators provide surface loosening of the soil after crushing and compaction.
