Description

The invention relates to agricultural machinery and can be used in agriculture when pruning (mechanized embossing) the ends of lash of melons and gourds in the tractor aisle.

The purpose of the invention is to improve the quality of the cut of the lashes.

FIG. 1 is a front view of a device for cutting gourds; in fig. 2 - the same, side view.

The device contains a flat disk 1, a rubberized wheel 2 with an adjustable pneumatic chamber 3, inclined at an acute angle to its plane, having a joint column 4, which is integral with the rack 5 of the U-shaped bracket 6 mounted on the front of the power means 7.

Rubberized wheel 2 is installed outside the working area inclined to the flat disk 1 at an angle d. The stand 5 of the bracket 6 is integral with the stand 4 of the axis 8 of the wheel 2 located at an obtuse angle () in the course of the movement of the unit.

The device works in the following way.

The rubberized wheel 2 with an adjustable low pressure pneumatic chamber, installed outside the working area with a stamping disc 1, moving across the surface of the soil 9 and pressing the lash 10 into the soil, performs the technological process due to resisting the lash to the blade of the disk with the force of a lash on the soil and rubberized wheel.

The maximum value of the area of contact of the whip with the wheel 2 and the soil is achieved by the fact that when moving the wheel 2 located obliquely to the flat disk 1

at an angle a, between the disk 1 and the wheel 2, a roller 11 of the soil is formed, along the perimeter of the cross section of which the lash is pressed against the soil and thereby increases the area of contact of the rod with the soil and, consequently, the resistance of the rod to its movement during cutting. In this way, a high-quality cut is achieved without moving the lashes and section 12.

The rubberized wheel 2 simultaneously serves as a support for the device, with respect to which the depth of stroke of the embossing disk is adjusted.

By installing the shoulder at the stand of the support-paddle wheel 2, regardless of the depth of stroke of the embossing disc 1 and the height of the support-paddle press wheel, reliable capture of lashes during the operation of the device occurs before reaching its critical point - the lowest point of the disc, i.e. During the work process, the whip is reliably protected, eats between the support-weave wheel and the soil, and does not reach the maximum set depth of the working body. By mounting the stand at an obtuse angle with a shallow depth of the course, the support-press wheel presses the cover to the soil closer to the lowest cutting point of the disk, while increasing the depth of the disk's stroke, the support-bearing press holds the cover much earlier and closer than the previous case, and thus provides, even with a significant depth of the working body, cutting the lashes at a shallow depth from the soil surface. Thus, the goal of improving the quality of the lash shearing is achieved.
