Description

The invention relates to agricultural machinery, in particular to a device for cutting the roots of seedlings of forest species.

A device for cutting roots is known, comprising a frame with support wheels and articulated vertical and horizontal working bodies pivotally connected to it by means of a ridge and loaders. [Patent for PM No. 54715, A01C 11/00 of 07/27/2006].

The disadvantages of this device include the complexity of the design and the simultaneous trimming of the rod and lateral roots of seedlings, as well as increased energy consumption for moving the cutting staples in the soil.

A device for cutting roots containing a frame, a band saw, each end of which is mounted on a corresponding slide mounted on a rail connected to the frame, and two crank-slide mechanisms of a band saw drive are known [Patent SU No. 1674707, A01B 35/22 of 05/18/1988 ]. The disadvantages of this device are the complexity and large overall dimensions of the structure (which, as a result, increases the energy intensity of the process), as well as the complexity of deepening the working body and the simultaneous trimming of the lateral and stem roots of seedlings of one row (which worsens their further survival).

There is also known a device for cutting roots, containing a frame, guides with removable cross members and sliders on which vertically cutting vibrating working bodies are fixed [Patent No. 2446654, A01B 39/12, A01B 35/02, 04/10/2012 Bull. No. 10 is a prototype].

The disadvantage of this device is the unreliability of the design due to the need to use an additional generator of forced oscillations, as well as the occurrence of alternating dynamic loads.

The invention solves the problem of improving the quality of trimming the roots of seedlings.

This is achieved by the fact that in the root cutter containing a frame with guides and vertically cutting working bodies, according to the invention, for cutting the lateral roots of seedlings, vertically cutting working bodies are used kinematically connected to the transfer shaft with bevel gears and flexible shafts, and the working bodies themselves are made in disks and are additionally equipped with protective covers.

The drawing shows a root cutter, General view.

On the frame 1 with the supporting wheels 2, a dispensing unit is installed, consisting of a hollow cylinder 3 with a distributing shaft 4 located inside it and boxes 5 with bevel gears 6 located inside them. Hollow posts 7 are connected to the boxes 5, a flexible shaft 8 passes inside each of them . To the racks 7 are attached drive units 9, which drive the vertical disk working bodies 10. To prevent open access to the working disk body, protective covers 11 are used.

Root cutter works as follows. To trim the lateral roots of seedlings, the root cutter is forcibly buried into the soil with the help of a tractor hitch, then the hitch is moved to a floating position and the device continues to move under its own weight at a depth regulated by the support wheels. The torque transmitted from the tractor power take-off shaft (not shown in the drawing) rotates the transfer shaft 4 with bevel gears 6, the rotation of which with the help of flexible shafts 8 is transmitted to the vertical disc working bodies 10. In this case, the working disc bodies 10 cut the side seedling roots.

Improving the quality of pruning of the roots of seedlings of forest species occurs due to a decrease in damage to the roots of seedlings (due to the rotational movement of vertically cutting disk working bodies). In addition, the simplicity of the design of the inventive root cutter, the absence of alternating dynamic loads, as well as the ability to control the rotational speed of disk working bodies depending on the type of soil and type of seedlings, allows you to form a developed fibrous root system of seedlings.
