RU45066U1 - WIDE CULTIVATOR - Google Patents

Abstract

The utility model relates to agricultural semi-mounted cultivators, aggregated with a tractor, for pre-sowing tillage. The cultivator contains articulated folding frames with cultivators, support wheels, linkage with press rollers, and a hydraulic system. In order to stabilize the process of loosening the soil at a given depth, the support wheels are located directly in the area of location of the cultivators, and spring corner levelers are installed on the front walls of the bearing beams with the possibility of moving them up and down the arc.

Description

The proposed utility model relates to agricultural semi-mounted cultivators, aggregated with tractors for pre-sowing tillage in order to create favorable conditions for the growth and development of plants.

Known combined cultivator (certificate for utility model No. 25821) containing the middle and side frames equipped with hydraulic cylinders, "S" -shaped cultivators mounted on the frames, transport chassis, packers and tow hitch.

Block-modular cultivators KBM-10.5P and KBM-15P are also known ("Federal Register of Agricultural Machinery". Catalog. Moscow. 2001.).

The latter, the closest in execution to the proposed utility model, consist of a hinged folding frame, a hitch, frames with "S" -shaped cultivators, packer rollers, and hydraulic systems.

The depth of loosening of the soil on these cultivators is determined by the position of the support wheels and press rollers.

The disadvantage of this design is the instability of the specified depth of loosening of the soil due to the fact that the support wheels are located on the front walls of the frames, therefore, the vertical load from the mass of the frames with cultivators is transferred to the packer rollers during translational movement, which, under the influence of this load, are buried in loose soil, clogged with soil, changing the depth of cultivation. In addition, cultivators are designed to work on soils with an even relief (KBM-13P cultivator, p. 48), and when treating soils with a comb surface, the effectiveness of transverse leveling of the field surface with packer rollers is reduced.

The purpose of the proposed utility model is to eliminate these disadvantages.

This goal is achieved by the fact that in the proposed utility model, the supporting wheels are located on the frames between the first and second rows of cultivators, and on the front walls of the beams are spring-loaded corner equalizers with the possibility of moving along the arc up and down.

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

Figure 1 - Side view of the cultivator in the working position.

Figure 2 - Top view of the cultivator.

Figure 3 - the equalizer.

The wide-cultivator (Figs. 1 and 2) contains the middle beam 1, side beams 2 and 3, articulated on the middle beam, middle frames 4 and side 5 and 6, mounted on the walls of the beams. The beams are equipped with hydraulic cylinders 7 for installing side beams with frames in a horizontal working position or vertical transport position.

The 4-row cultivators of the “S” -shaped form are fixed on the frames 8. Between the first and second rows of cultivators, support and running wheels are coaxially mounted on the frames: the central 9 and the side 10. The central wheels are equipped with hydraulic cylinders 11, and the side wheels are equipped with a screw pair 12 for wheel height settings.

On the front walls of the beams (Fig. 3), racks 13 are fixed on which angular equalizers 14 with springs 15 are pivotally mounted. Stepwise adjustment of the angular equalizer in height is carried out by raising or lowering the racks relative to the frames with fixing with a finger 16.

A suspension 17 with a rolling roller 18 is mounted on the rear walls of the frames. Stepwise adjustment of the roller in height is carried out by raising or lowering the suspension strut 19 relative to the frame with a finger lock.

The hitch 20 has a support post 21.

In one working pass, the cultivator performs the following operations:

- aligns the relief of the field;

- loosens the soil to a predetermined depth;

- crushes the soil with a roller.

The location of the support wheels in the area of the main working bodies - cultivators stabilizes the process of loosening the soil at a given depth and improves the working conditions of the packer rollers.
