Description

The invention relates to the field of agricultural engineering, in particular to a device for removing tops from root crops.

A device is known for separating tops from root crops on the root, including cutting and ejecting tops of root crops (SU 1630645, 02.28.1991), including a vertical drive shaft with elastic blades radially mounted on it.

The closest analogue of the claimed invention is a device for removing root crops of tubers, including a frame with a linkage to the traction means and support wheels mounted with the possibility of changing the height of the tops of the tops, vertical shafts with a drive and working elements radially rigidly fixed at their lower ends (RU 2361399 C2 March 27, 2009).

A common disadvantage of the known devices is the limited technological capabilities that do not allow the device to be used for removing tops in crops of root crops with different row spacings, due to the vertical shafts with working elements permanently mounted on the drive frame.

The task of the claimed invention is to remedy this drawback.

The technical result of the invention is to expand the technological capabilities of the device due to the possibility of its use in crops of root crops with different row spacing.

The specified technical result is achieved by the fact that in the known device for removing root crops of tubers, including a frame with a linkage mechanism to the traction means and support wheels mounted with the possibility of changing the height of the tops of the leaves, vertical shafts with a drive and working elements radially rigidly fixed at their lower ends, according to the invention, the support wheels are mounted to move along the frame to change the gauge, and the frame along its longitudinal axis is equipped with a slot in which With the possibility of longitudinal movement and fixation, hydraulic motors are mounted, and each vertical shaft is rigidly fixed to the output shaft of the hydraulic motor.

In addition, the working elements are made of flexible high-tensile elastic material.

In FIG. 1 shows a General view of the device in the idle position, side view;

In FIG. 2 - the same, top view.

The device comprises a frame 1 with a linkage mechanism 2 to the traction means (not shown in the drawing) and support wheels 3 mounted to change the height of the top of the top by moving the wheel struts along the locking brackets 4 up or down and the ability to change the gauge by moving the wheels along the adjustment the bracket 6 by loosening the brackets 4. The frame 1 is provided with a slot 5, in which the hydraulic motors 7 are mounted with the possibility of lateral movement and fixing. Fixing is done by bolting, and displacements manually after loosening. Each vertical shaft 8 is rigidly fixed to the output shaft of the hydraulic motor 7. At the lower end of each vertical shaft 8, a rotor 9 is radially rigidly fixed, on which four working elements 10, made of flexible high-strength elastic material, are fixed at an angle of 90 degrees to each other. As such material can be used, for example, polyurethane, nylon.

The device operates as follows.

Depending on the width of the row-spacing, the hydraulic motors 7 are moved in the slots 5 by loosening the bolted connection and fixed after adjustment is completed. The support wheels are moved relative to each other to the required gauge along the adjustment bar 6 by preliminary loosening the locking brackets 4 to the required gauge, depending on the width of the row spacing of the root crops. Wheel racks also move along the brackets 4 up or down, depending on the required height of the tops of the cut. Hydromotors 7 receive a drive from a standard pump of traction means through flexible hoses (not shown in the drawing) that drive vertical shafts 8 with working elements 10 of flexible flexible material that begin to rotate in a horizontal plane.

In the process of cutting the tops, the working elements 10 perform both rotational and translational-translational motion, moving along the cycloid. The translational motion determines the feed rate of the working element when cutting the tops of plants. Working elements made of flexible flexible material, such as polyurethane, nylon, provide the capture and cutting of the tops, but do not damage the root crops.

Using this device will allow you to work on crops of root crops with different row spacing, as well as significantly reduce the trauma of the root crop when cutting tops.
