SU895299A1 - Arrangement for soil tilling in perennial plant row - Google Patents

Description

one

FIELD OF THE INVENTION The invention relates to agricultural mechanical engineering, in particular, to tillage crops for vineyards.

A tool for tillage in rows of perennial plantings is known, including a knife-type working tool, a probe, a hydromechanical mechanism for switching on the working organ Ll. A disadvantage of the known tool is the design complexity and unreliability of work due to false triggerings of the following probe on a branch of low yogic cultures.

It is also known to tillage a number of perennial plantations, including a frame, a knife-shaped working body connected to the frame by means of a spring-loaded lever L2.

The disadvantage of this device is the unreliability of work due to the false positives of the next probe on the branch of low-stem cultures.

The aim of the invention is to increase the quality of processing of interstitial strips of low-stem cultures.

This delight is achieved by supplying the working body with an additional knife rigidly attached to the main knife and set at an acute angle to it and to the direction of movement.

HA FIG. 1 shows the proposed device, a top view, in FIG. 2 - the same, side view.

The device consists of a frame 1, the working body 2 in the form of the main

15 of the knife 3 and installed at an acute angle to it and to the direction of movement of the additional knife 4 rigidly attached to the knife 3. The working body 2 is connected with the frame 1 by

20 provided with a spring 5 of the telescopic lever 6 and the lever 7.

Claims (2)

The adaptation works as follows. 3 When the machine is moving in between the main knife 3 and the additional knife 4 are buried in the soil, so that the soil is resistant to cutting, it tends to turn the levers and the knife 3 in a row of plantations, while the soil resists acting on the knife 4, strives to implement a working body from the row. The spring 5 is selected in such a way that the force created by it, together with the resistance of the soil acting on the knife 3, compensates for the resistance of the soil acting on the knife 4. When the knife 4 interacts with the stem of the plant, the working element is removed from the row. In this case, the knife 4 bends around the stem of the plant, gradually touching it, so that the raw area around the stem is reduced, and the knife itself 4 at the time of the stem removal is a copying probe that is not affected by low growth, and no branches of the plants. After passing the trunk, the working organ returns to the row of plantations. The use of the proposed tillage tool in a series of perennial plantings will reduce the non9 zones around boles to the cultivated plants and eliminate false arrays of the working body when processing low-stem crops. The invention The device for tillage in a number of perennial plantations, including the frame, the working body in the form of a knife, connected to the frame by means of a spring-loaded lever, which is characterized by the fact that, in order to improve the quality of treatment of the inter-stem strips of low-cut crops, the working body is equipped with an additional knife rigidly attached to the main knife and set at an acute angle to it and the direction of movement.
