Abstract

FIELD: agriculture.

SUBSTANCE: device contains a frame with fixed weed removing units and rotary tools mounted behind them. The frame is mounted on a hitch linkage with a self-setting parallelogram mechanism. The parallelogram mechanism has a hydrocylinder and a flow control device controlling it from feelers through kinematic connection. Rotary tools have tilted axes of rotation enclosed in shrouds, and elastic elements, drive connection and hold-in discs installed over rotary tools. Each hold-in disc is provided with radially positioned pins and a cradle. Using the cradle the hold-in disc is fixed to the shroud of axis of rotation of the tool using hanger rods of adjustable length, a bearing and a clamping sleeve with a screw.

EFFECT: constructive implementation enables to improve the quality of disclosure of root system of clonal rootstocks prior to their separation from parent plants.

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.

Known rotary working body [A.S. USSR No. 933011, A01B 39/16], including conical working bodies with knives mounted on the frame by means of inclined axes and safety shields located on the side of the plants. In operation, protective shields keep cut plants from being scattered.

However, the known device does not exclude breaking out shoots of vegetatively propagated stocks when the root system is opened before they are separated from the uterine plants by rotary working bodies with elastic elements, since the protective shields located on the side of the plants do not hold them in the direction of the row.

A device for processing soil in the rows of plants [A.S. SU No. 1729311, А01В 39/16], comprising a self-steering parallelogram mechanism with a gearbox, working bodies with a vertical axis of rotation and protective discs with an elastic rim mounted above it. In the work, protective discs compress cultural plants, orient the working organs in accordance with the location of these plants in a row and provide support for the shoots when the working organs act on the root system.

A disadvantage of the known device is that when it opens the root system of vegetatively propagated stocks before they are separated from the uterine plants, it does not exclude the breaking of tender shoots by rotor working bodies due to the impossibility of fully coordinating the moments of crimping plants with elastic disks and the impact of these working bodies on the root system.

A device for disclosing the root system of vegetatively propagated stocks before their separation from uterine plants [Application No. 2006113261/12 (014415), 04/19/2006 - prototype], containing a frame mounted on a mounted device using a self-mounted parallelogram mechanism having a hydraulic cylinder and a control to them from the copiers by means of kinematic connection, a hydraulic distributor mounted on the frame otpashniki and behind them rotary working bodies with inclined axes of rotation enclosed in casings, and elastic elements and drive.

A disadvantage of the known device is that rotary working bodies break out delicate shoots of vegetatively propagated stocks from uterine plants, scatter and damage the separated shoots, subsequently reducing the productivity of mother liquors, while the broken shoots clog the working bodies and disrupt the technological process.

A device for opening the root system of vegetatively propagated stocks before their separation from the uterine plants is proposed. It comprises a frame mounted on a hinged device using a self-aligning parallelogram mechanism having a hydraulic cylinder and controlling the valve from the copiers by kinematic communication, mounted on the frame of the tillers and rotary working workers behind them organs with inclined axes of rotation enclosed in casings and elastic elements, drive and mounted on rotary work their bodies retaining discs, characterized in that each retaining disk is provided with radially extending fingers and cradles, whereby said disc is secured to the housing rotation axis of working body via suspensions adjustable length, bearing and adapter sleeve to the nut.

High-quality work of the proposed device is achieved by the fact that the retaining discs penetrate with their fingers through a number of plants, providing a backing of the processed layering throughout the impact on the root system of elastic elements of rotary working bodies. Thus, in the process of opening the root system of vegetatively propagated rootstocks, the shoots constantly have additional backing from the holding discs, which reduces the force exerted on the uterine plant, thereby eliminating the breaking of tender shoots.

The presence of a cradle, by means of which the holding disk is fixed to the casing of the axis of rotation of the working body with the help of suspensions, supports and an adapter sleeve with a nut, makes it possible to adjust the optimal position of the plane of the disk in accordance with the inclination of the axis of rotation of the working body and create the conditions for the best penetration of fingers into the mass of plants and rolling retaining discs along a row.

Figure 1 shows the device, side view; figure 2 - a view of figure 1; figure 3 - mounting of the retaining disk on the casing of the axis; 4 is a diagram of the interaction of the holding discs with layers.

A device for revealing the root system of vegetatively propagated stocks contains a frame 1 mounted on a mounted device 2 using a parallelogram mechanism 3 having a hydraulic cylinder 4 and controlling it from copiers 5 by means of a kinematic connection 6 hydraulic distributor 7. On the frame 1 are mounted symmetrically otpashniki 8 and rotary after them working bodies 9 with inclined axes of rotation 10 enclosed in casings 11, elastic elements 12 and drive 13. Above the rotary working bodies 9, holding discs 15 are mounted on bearings 14. Each disk is equipped with pins 16 and a cradle 17, by means of which it is mounted on the casing 11 using pendants 18, supports 19 with an arm 20, an adapter sleeve 21 and a nut. Locking washers 23 are provided for fixing nuts 22. Suspensions 18 are connected to the cradle 17 by ball joints 24, and in the brackets 20 are fixed with nuts 25.

The device operates as follows.

When the device moves over the axis of the row 26, the hydraulic cylinder 4, controlled from the copiers 5 by means of the kinematic connection 6 of the hydraulic distributor 7, orientates the frame 1 in accordance with the arrangement of plants in a row. Otpachniki 8 destroy the soil shaft from the sides and shift the soil towards row spacing. Rotating towards each other, rotary working bodies 9 with elastic elements 12 destroy the soil in a row, shake it from the roots of plants 27 and discard it in the direction of row spacing. In this case, the holding discs 15 penetrate with their fingers 16 through a series of plants, providing a backwater for the processed layering. If necessary, before starting work, the optimal position of the clamping disks is established by moving the adapter sleeves 21 in height and tilting them to the axis of rotation of the working bodies by changing the length of the suspensions 18, depending on the size of the cover shafts, the width and condition of the plant strip, and the set speed.

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.
