Usage: agricultural engineering. SUMMARY OF THE INVENTION: the implement includes a tractor, an attachment 1 and a tillage implement with an arched frame 2, which is connected to the attachment 1 by a longitudinally horizontal hinge 9. The hinged device 1 is mounted on the side of the tractor via a horizontal-horizontal hinge 10. The working bodies 6 and the support wheels о mounted on the frame 3, one of which is mounted on the arch frame 2, and the other on the mounted device 1. The support wheels 8 are mounted at an angle to each other and are located behind the working bodies 6 along the two voltage unit. 1 C.p. f-ls, 3 ill.

Description

The invention relates to agricultural machinery, and more particularly to machines for cultivating tall crops.

A plant-growing plant care device is known, which is a hinged frame / mounted on a tractor with vertical reducers. A disadvantage of the known design is the presence of horizontal hinges located in the upper part of the frame, which, with large irregularities in the soil surface, leads to a decrease in the quality of copying the relief, and the working bodies.

located on opposite sides of the tractor do not limit the width of the row of plants along its entire length. With such an aggregate it is impossible, for example, to process a series of raspberries of a given width, certain boundaries of which are necessary for the high-quality operation of the raspberry harvester.

Closest to the technical nature of the claimed device is a prototype unit for work on planting tall crops, which is a semi-mounted gantry frame. A three-point hitch allows you to hold the unit in a certain position during operation.

A disadvantage of the known construction is the dependent position of the working bodies of one rotor from the other when processing the soil, which ultimately affects the unsatisfactory copying of the fruit s.

The purpose of the invention is to improve the performance of the unit by increasing the reliability of copying the relief and ensuring the width of the row of tall crops.

This goal is achieved in that the machine, located on one side of the tractor, comprises an attachment and a tillage implement connected to it by means of a longitudinally horizontal hinge, and an arched frame with working bodies and support wheels.

Comparative analysis with an analogue and a prototype shows that the device is characterized by the presence of two frames for fastening the working bodies and the support wheels, one of which is mounted on a hinged device, and the second on the free end of the arch frame, and the hinged device is made in the form of a beam fixed by means of a horizontal horizontal the hinge on the side of the tractor, and the hinge of the arch mount

the frame to the attachment is mounted between the hinge of the attachment of the attachment to the tractor and the mounting frame of the working body and the support wheel.

The hinge of the attachment of the attachment allows you to quickly transfer the unit from its working position to the transport.

In FIG. 1 shows a machine, front view; in FIG. 2 - the same side view; in FIG. 3 is a plan view.

The unit contains an attachment

I and arch 2 with frames 3 placed on them, to which hydraulic motors 4 are attached, rotors 5 with working bodies 6, which are located at an angle of 5-7 ° to the horizon in order to copy the root system of plants, belt drives 7 and support wheels 8 placed behind the working bodies in the direction of movement of the unit at an angle to the soil surface (see Fig. 1). In the attachment, longitudinally horizontal joints 9 and 10 are located.

II is attached to the skeleton of the tractor and to the attachment. Chain 12 connects the attachment 1 and arch 2 to rotate the latter by a certain angle when the working bodies are deepened.

The proposed unit operates as follows.

It is mounted on the side of the tractor using a longitudinally horizontal hinge 10 and a hydraulic cylinder 11. The torque on the rotors 5 is transmitted from the hydraulic motors 4 by means of a belt transmission 7. The tractor driver drives between rows of tall crops, includes hydraulic motors and saddles a number of plants, for which he lowers the arch 2 by means of the hydraulic cylinder 11 to the floating position until the support wheels 8 touch the ground. The unit begins to move along the row, processing from two sides of it two strips of width equal to the diameter of the rotors, while simultaneously forming (notching) a row of a strictly defined width along its entire length.

When, for example, the left wheel 8 is hindered (or deepened in the soil), the copying of the right rotor is not disturbed, and due to the horizontal hinge 9 being located at a relatively small distance from the ground, the copying process of the left rotor is insignificant. A similar pattern is observed when the right support wheel 8 collides with an obstacle or recess.

The extension of the working bodies from the soil is carried out using a hydraulic cylinder 11 and an adjustable chain 12, which does not give

freely rotate arch 2 relative to attachment 1.

In addition to the working tools, a sprayer or trimmer can be hung on the arch.

The economic effect is achieved by improving the quality of soil cultivation by copying the relief and fruit wall of plants, as well as by increasing labor productivity,
