Abstract

Use: tillage in rows of woody plants with a minimum untreated area around the plants. The invention: the device contains a self-guided parallelogram mechanism with a reducer, cone-shaped working bodies with a vertical axis of rotation and protective discs mounted above them with an elastic rim. Each working body is equipped with flexible elements of various rigidity installed on its conical surface. The stiffness of the elements decreases from the axis of rotation of the rotor to its periphery. 2 Il.

Description

The invention relates to agricultural machinery, in particular, tillage tools in nurseries.

The following device is known in the form of two cylinders which run freely over a number of plants. The cylinders are metal-intensive, and the connection of the cylinders with working bodies is carried out through complex mechanisms causing large protective zones at the bases of the plants.

Closest to the present invention is a device including a self-aligning parallelogram mechanism with a drive mounted on it, two vertical shafts with disk working bodies, which, in addition to cutting the plants, cut the soil shaft, i.e. perform a tillage process.

The disadvantage of this device is damage to plants by working bodies due to

that the tracking of a variety of plants occurs by the working bodies themselves.

A device is known that includes working bodies with a vertical axis of rotation mounted on movable spring-loaded frames, the working body being made in the form of a cone-shaped frame with cutting edges, and supporting and protective disks are mounted above the frame.

The disadvantage of such a device is damage to plants, namely, the root system near the plant stump.

It is also known a device for spring unraveling of plants, made in the form of a circular brush with elastic elements made of pile, with a vertical axis of rotation, which, in addition to unrailling of plants, also destroys young weeds.

However, such a device works only on the pre-loosened layer of XI

chaps, does not contain the elements of loosening the soil, on the copy of a number of plants.

The purpose of the invention is to reduce untreated areas near plants without damaging cultivated plants and simplify the design of the device.

To achieve this goal, in a device containing a self-aligning parallelogram mechanism with a drive mounted on it, two vertical opposing rotating shafts, supporting rotors with elastic inverted cantilever part downward elements, elastic elements of the central part of the rotor have a radial outreach and greater rigidity compared to the elements peripheral part.

Making flexible elements in the central part more rigid, for example by increasing their diameter or making them from steel rods, provides deep soil loosening in the zone remote from the plant. At the same time, the flexible elements of the peripheral part, made, for example, of nylon piles of smaller diameter, deflection, remove only weed grass and do not injure either the roots of plants (as they penetrate shallow depth into the soil) or the plants at their random mutual contact. Freely rotating wheels due to friction in the bearings also receive counter-rotation, which provides minimal effort for their rotation upon contact with plants during the copying of a row, respectively, minimal force for moving the parallelogram self-adjusting mechanism. The radial overhang of the flexible elements relative to the rotors and the geometric alignment of the sizes of the elements, the rotor and the wheel allows to reduce the untreated area near the plants. The attachment of flexible cantilever elements to the conical surface of the rotors along the normal line makes it possible to eliminate mechanical damage to plants by the rotors and at the same time actively influence the elements on the weeds.

FIG. Figure 1 shows a soil treatment device in rows of plants, side view; in fig. 2 - the same, top view.

The tillage device in rows of plants has a front beam 1, a rear movable beam 2 with a drive and a gearbox 3. The bars are interconnected by hinge links 4. On the moving beam there are two vertical shafts 5 with rotors 6 and free running wheels 7. On conical surface 8 of each rotor along the normal to it fixed flexible elements

9 variable length. At the same time, the elements 9 mounted on the edges of the rotors have a stiffness less than those installed closer to the axis of rotation of the rotor.

For operation, the device is installed above the p-axis. As the wheel 7 moves, it is driven around a row of cultivated plants due to the reaction from the plant trunks orient the movable beam 2 with the drive and rotors b in accordance with the arrangement

plants in r d. Rotating towards each other, the rotors used to brush weeds from between the rows and protective zones. This happens as follows. Flexible elements 9, fixed closer to the rotor axis, are loose

Weed out the soil and remove the weeds from between the spaces. And the elements of lesser rigidity, protruding lower ends behind the rigid elements of the rotors, comb weeds out of protective zones. Possessing less rigidity, these elements do not damage cultivated plants. ,
