Abstract

A universal cultivator for inter-row tillage, consisting of a coupler, support wheels, a frame and several rows of working sections fixed on it, characterized in that, in order to improve the quality of soil cultivation, the unit has, in addition to the cultivator leg, an additional disk working body (cultivator) , consisting of discs of different diameters, rigidly fixed to the shaft of the fork by means of spacers and clamping nuts.

Description

The utility model relates to agricultural machinery, in particular to disk implements designed for inter-row tillage, and can be used in tillage machines and implements.

A cultivator is known in which there is a device for inter-row processing of plants, containing sections of working bodies mounted on the frame, each of which has a longitudinal bed, with a lancet foot, a pair of needle discs and a rotating working body sequentially mounted on it, characterized in that the device is rigidly equipped fixed to the frame with a supporting ski and a pair of rotary wire-frame working bodies mounted on inclined shafts that are connected to each other by a chain transmission and bevel gear. A device, characterized in that the ridges are installed with the possibility of changing the height of its location relative to the support ski (application No. 2002135876 published 2004.06.20.).

The disadvantage of this design is the complexity of the design and its maintenance. As for the working bodies, in the process of operation of the unit there is a chance of clogging of the rotary frame-wire working bodies.

The closest in technical essence is the unit for inter-row tillage and fertilizing row crops, consisting of a coupling device, a frame with wheels and sections attached to the frame with wheels and working bodies. The tractor has a synchronous drive to the power take-off shaft. A transmission mechanism has been made on the frame, transmitting torque from the power take-off shaft to the wheels of the section. Blades are made on the wheels of the section, forming a dihedral angle with a plane drawn through the base of the blade tangentially to the wheel of the section, and disks, dividing in half along the vertical plane of the blade. When the unit moves on the blades from the soil side, a reactive force arises in the direction of movement of the unit, forming a driving force on the wheels of the section, transmitted to the coupling device. And also there is a decrease in soil resistance to the advancement of the working body due to the separation of the soil by the blades across, and by the disk along the row-spacing (patent RU No. 2257701 published 2005.08.10).

The disadvantage of this design is that the working bodies are driven from the power take-off shaft, which increases the metal and energy consumption of the structure, the cost of its manufacture, the complexity of maintenance and repair.

The purpose of the utility model is to improve the quality of inter-row tillage, using the simplified design of the unit, in comparison with similar typical cultivators.

This is achieved by the fact that the universal inter-row cultivator consists of a hitch, support wheels, a frame and several sections attached to it. The sections of a universal inter-row cultivator contain a parallelogram mechanism in which there is a copying wheel of the section, a cultivator leg and a disk working body (cultivator), which, according to a utility model, consists of a fork fixed in supports on the frame of the section, flat disks of different diameters, the contour of which will be repeat the shape of the row. The disks are fixed on the shaft of the fork, by means of spacer sleeves and two clamping nuts.

Due to this design of the disk working body (cultivator), high-quality loosening of the soil, cutting of soil lumps in the inter-row space, cutting of the root system of weeds, reduction of soil resistance to the cultivating paws will occur.

Figure 1 is a General view of the unit from the side.

Figure 2 is a General view of the unit from above.

Figure 3 is a frontal section of the disk working bodies (ripper).

The unit consists of a coupling (2), support wheels (1), a frame (load-bearing beam) (3), on which working sections (10) are installed, having a parallelogram mechanism (4). In the sections there is a copying wheel (5), a cultivating leg (11), a disk working body (cultivator) (16), consisting of a fork (6) fixed in supports (12) on the frame of the working section (10), and disks of different diameters (8), fixed by means of spacer sleeves (14) and two nuts (15), on a shaft (13) installed in the yoke supports (7). Also, in order to avoid clogging of the interdisc space, the unit is equipped with a scraper (9).

This unit can be used for row cultivation in rows between crops. The disk working body (ripper) (16) of the cultivator can be installed on serial cultivators. A universal cultivator operates as follows. The aggregation of sections, their number per tractor is dependent on the available power on the hook. For efficient operation, the frame of each section (10) of the unit is equipped with a parallelogram mechanism (4), on which a copying wheel of the section (5), a cultivating paw (11) and a disk working body (ripper) are attached (16). When the cultivator moves, the working section (10) copies the relief of the field, due to the copying wheel (5) and the parallelogram mechanism (4), as a result of which, the cultivator leg (11) is constantly at the set depth. In front of the cultivating paw (11) is a disk working body (ripper) (16), consisting of a number of disks (8) of different diameters, the contour of which follows the shape of the row. Disks (8) are fixed at equal distances between each other, on the shaft (13) of the working body, which, in turn, is mounted on a fork (6) by means of supports (7). The disk working body (ripper) (16) is deepened to a depth determined by its mass. When the unit moves more intensively, the process of cultivation of the soil occurs, which is accompanied by cutting of soil lumps, cutting of the root system of weeds and loosening of the "rain crust", which in turn reduces the traction resistance of the cultivator paws. Thanks to which it will be possible to increase the number of sections of the unit.

These additional effects of the disk working body (ripper) (16) on the soil are the technical result of the utility model.

As for industrial applicability, no scarce materials or impossible technologies were used here. The universality of the cultivator for inter-row tillage with the proposed disk working body (cultivator) lies in the fact that it can be used on any serial cultivator. This will greatly reduce the cost of cultivator in the manufacture.
