Description

The utility model relates to agricultural engineering, in particular to combined tillage implements for basic soil cultivation.

A known tillage unit includes a frame, disk batteries installed at an angle to its transverse line, paws, a leveler, front and rear rollers with working elements on their surface (SU, copyright certificate 1523066, class A01B 49/02, 1989) .

The main disadvantages of this unit are its large length, poor maneuverability, increased traction resistance, and when moving across a slope it is unstable, because its leveler and rollers slide down the slope.

A soil-cultivating combined unit is known, including a frame, a hitch, support wheels, disk batteries, flat-cutting paws, brackets with which spring-loaded frames are hinged (SU, copyright certificate 2119734, class A01B 49/02, 1998).

The disadvantages of this unit are:

- large kinematic length of the unit;

- the absence in the design of the unit of devices that allow changing the angle of attack of disk batteries;

- inability to change the pressure of disk batteries on the soil;

- high traction resistance of the unit.

Well-known row-crop combined cultivators SOLAR FIELDS: KD-570M, KD-720M http://web.archive.org/web/20190222235521/https://agropuls.com/production/selhoztehnika/

pochvoobrabativayshaya-technika/kultivatory/propashnye_kombinirovannye_kul_tivatory_solar_fields_kd_570m_kd_720m.html. The KD family of row-crop cultivators represents a wide range of trailed row-crop combined cultivators with a working width from 5.7 to 7.2 meters, capable of performing up to five operations simultaneously in one pass (chopping crop residues and crumbling the top layer of soil, cutting weeds and loosening bottom layer of soil, combing out clipped weeds, creating a mulch layer, leveling and rolling the field surface). These cultivators contain in their design a frame, a towbar, support wheels, flat-cutting shares, spherical disks mounted on movable racks, a harrow with a spring tooth, combing and compacting rollers.

The disadvantage of these units is the increased traction resistance due to the use of spherical disks in front of the flat-cutting paws.

We have adopted the design of these row-crop combined cultivators as the closest analogue. The essence of the claimed utility model is as follows. The problem that the useful model is aimed at solving is the simultaneous cutting of plant residues and soil in front of the flat-cutting paw, which helps reduce the traction resistance of the unit.

The technical result is a reduction in traction resistance.

This technical result is achieved by the fact that in the known universal combined unit for decompaction and soil cultivation, containing a frame with an attachment, support wheels, flat-cutting paws and disks according to the utility model, coulter discs with a safety mechanism are installed in front of the flat-cutting paws.

The utility model is illustrated by drawings.

In fig. 1 – shows a side view of the universal combined unit.

In fig. 2 – shows a universal combined unit, top view.

Information confirming the possibility of implementing the claimed utility model is as follows.

The universal combined unit consists of a frame 1, on which a linkage 2 is installed in the front part, and two support wheels 3 are installed behind it on the frame 1. In the lower part, coulter disks 4 with safety mechanisms 5 are attached to the frame 1, behind which flat-cutting paws are installed 6.

The universal combined unit works as follows.

Before starting work, the universal combined unit must be installed on a flat, hard horizontal surface, after which, attach the universal combined unit to the tractor using a trailed three-point hitch and adjust the horizontal level of the attached universal combined unit. Adjustment of the tillage depth is carried out in the working position using support wheels 3. The transfer of the universal combined unit from the transport position to the working position is carried out using an attachment 2. When the universal combined unit moves across the field in the working position, the coulter discs 4 cut the soil and plant residues, copy quality field relief and individual adjustment of the cutting depth with coulter discs 4 is carried out using safety mechanisms 5. Behind the coulter discs 4 there are flat-cutting paws 6, which perform basic tillage without turning the layer to a depth of 30 cm.

The declared utility model meets the requirements for novelty and significant distinctive features. The use of a universal combined unit makes it possible to reduce traction resistance due to preliminary cutting of soil and plant residues with coulter discs.

Claims (1)

A universal combined unit for decompaction and soil cultivation, containing a frame with a mounted device, support wheels, flat-cutting paws and disks, characterized in that coulter discs with a safety mechanism are installed in front of the flat-cutting paws.
