Description

The invention relates to agricultural machinery and can be used for mechanization of work in horticulture, in particular for the disclosure of the root system of vegetatively propagated stocks before their separation from uterine plants.

A device for opening uterine plants of vegetatively propagated stocks [1, p. 9-10], comprising a round nylon brush mounted on a frame with support wheels, mounted on a vertical shaft, the axis of which is inclined forward along the machine.

The disadvantage of this device is that the round nylon brush does not provide high-quality disclosure of the uterine plants of vegetatively propagated stocks in areas with compacted covering soil layer and on medium and, especially, heavy soils.

A device for disclosing the root system of vegetatively propagated stocks [2 - prototype] before separating them from the uterine plants, containing a frame mounted on a hinged device using a self-aligning parallelogram mechanism equipped with a multiplier, mounted on the frame, tillers and behind them rotary working bodies with an inclined axis rotation and elastic elements, drive and copying discs.

During operation, the fenders act on the cover shaft and partially destroy it. The rotary working bodies with elastic elements, following the tillers, penetrate between the roots of the plants, shake out the soil and discard it towards the row-spacing.

The disadvantage of this device is that the elastic elements of rotary working bodies penetrate poorly between the roots of vegetatively propagated rootstocks growing in a strip and having a fibrous root system, which leads to a decrease in the quality of work performed, especially in areas with a compacted soil cover shaft.

A device is known for tillage in rows of plants [3], comprising a self-guiding parallelogram mechanism with a rotor, cone-shaped working bodies with a vertical axis of rotation, and flexible elements of different stiffness mounted on their cone-shaped surface.

However, such working bodies also poorly scrub soil from the inter-root space of vegetatively propagated stocks. This is because the elastic elements of the working bodies when they meet obstacles in the form of skeletal roots bend, slide along the obstacle and are not able to influence the soil inside the lobe of the root system.

A device for opening the root system of vegetatively propagated stocks before their separation from the uterine plants is proposed, comprising a frame mounted on a hinged device using a self-aligning parallelogram mechanism equipped with a multiplier, mounted on the frame, tillers and behind them rotary working bodies with an inclined axis of rotation and elastic elements, drive and copiers, characterized in that the elastic elements of the working bodies are provided with additional weights fixed to their free con zakh, and the drive - a device for controlling the speed of working bodies.

Additional weights secured to the free ends of the elastic elements, having centrifugal force, encounter obstacles in the form of roots of vegetatively propagated stocks, firstly, shaking the soil located between the roots, which then crumbles under the moving elastic elements. Secondly, elastic elements with additional weights at the ends under the influence of inertia force more efficiently penetrate the lobes of the root system of stocks and scoop out the soil from there.

The device for controlling the speed of the working bodies allows you to set the optimal modes for specific conditions, depending on the type of soil of the cover shafts and the state of the root system of stocks.

All this ultimately significantly improves the quality of the disclosure of the root system of vegetatively propagated stocks before their separation from the uterine plants.

Figure 1 shows the device, side view; figure 2 is a view along arrow A of figure 1; figure 3 is a section along the elastic element with a load.

A device for revealing the root system of vegetatively propagated stocks contains a frame 7 mounted on a mounted device 2 by means of a self-aligning parallelogram mechanism 3. The parallelogram mechanism 3 is equipped with a multiplier containing a hydraulic cylinder 4, a hydraulic distributor 5, copiers 6 and a kinematic connection 7 between the copiers 6 and the hydraulic distributor 5. On frame 1 mounted symmetrically otpashniki 8 and behind them rotary working bodies 9 with elastic elements 10, the drive 11 and the speed control device 12. Each elastic member 10 is provided with additional weights 13 secured to its free end. The elastic element 10 can be made, for example, of a steel rope, and the load 13 - in the form of a steel sleeve mounted on the rope and fastened with it by means of a weld 14. The ends of the sleeves facing the axis of rotation of the working bodies 9 have a bevel 15, converging no to the forming surface of the elastic element 10.

The device operates as follows.

The device is mounted on the tractor and its PTO shaft is connected to the shaft 16. When the unit moves over a number of plants 17, copiers 6, acting through a kinematic connection 7, a distributor 5, a hydraulic cylinder 4, orient the frame 1 in accordance with the position of a number of plants 17. The cultivators 8 destroy the soil a shaft from the sides of a number of plants 17 and discard the soil in the direction of row spacing. Rotating towards each other, the rotor working bodies 9 with elastic elements 10 destroy the soil in a row, shake it from the roots of the plants and throw it towards the same row spacing. Additional loads of 13 elastic elements 10, having centrifugal force, shake the soil more energetically, and when faced with an obstacle in the form of roots of vegetatively propagated stocks, firstly, they shake the soil located behind the roots, which then crumbles under the moving elastic elements, and, secondly, under the action of centrifugal force, elastic elements with additional weights at the ends more effectively penetrate the lobes of the root system of rootstocks and scoop out the soil from there. Chamfer 15 ensures that the load glides along the roots and eliminates damage to plants.

The device for controlling the rotation speed of 12 working bodies, for example, a variator or gearbox, allows you to set the optimal modes depending on the type of soil of the cover shafts and the state of the root system of vegetatively propagated stocks.

The effectiveness of the device is achieved by significantly improving the quality of the disclosure of the root system of vegetatively propagated stocks before they are separated from the uterine plants.
