Description

The invention relates to earthmoving machinery used in land reclamation construction and the peat industry, in particular to disc milling machines for performing slit drainage.

The purpose of the invention is to reduce the energy intensity of the cutting process and expand technological capabilities through the development of both thawed and frozen soil.

FIG. 1 shows the working body, general, its form; in fig. 2 - the same, rear view.

The working member contains a frame milling cutter 2 mounted on the frame 1, which simultaneously performs the function of a supporting ski, mounted on the shaft 3, rotated from the shaft 4 of the power take-off of the base machine through the gearbox 5.

The disk milling cutter 2 has cutters 6, installed symmetrically with respect to their transverse plane on both sides of the disk milling cutter 2 in a checkerboard pattern with an inclination of 15–25 ° forward with respect to the radius and 1–30 ° to the side relative to the plane of the disk. The drive shaft 3 of the disk milling cutter is connected to a gearbox 7, on the output shaft of which a cutting disk 8 is fixed with cutters similar in construction and installation angles to the cutters 6. The frame 1 is provided with a vertical support plate 9 located in the free space between the disk cutter and the cutting disk 8.

The disk mill 2 and the cutting disk 8 cover the casings 10.

The working body works as follows.

The working tool is installed on the drain path to the draining channel and lowers the machine into it. The disk milling cutter 2 and the cutting disk 8 are driven in rotation from the shaft 4 of the power take-off of the base machine. When moving forward, the disk milling cutter 2 with the incisors 6, cuts through the soil, namely peat, and stumpy inclusions, discarding the excavator.

viral primer on the housing 10 back along the car.

Cutting peat due to the installation of incisors 6 with an inclination to the side relative to the plane of the disk is carried out only by the front edge of the incisor, which drastically reduces the energy intensity of the process. The loosened peat is excavated from the slot by the front plane of the same cutter 6, set inclined to the radius of the disk.

The cutting disk 8 cuts a slot at an angle to the disk cutter 2, rotating at the same linear speed. The cut-off triangular monolith of peat is supported from lowering down by the plate 9, and after passing the machine it is lowered into the drainage slot made by the disk cutter 2 until seized. The recess formed at the site of the drain is filled with peat, thrown out of the slots by the cutter 2 and the cutting disk 8.

When the cutting edges of the incisors 6 are blunt, they are moved to the opposite plane of the disk. Sharpening of the cutting edges is made only after the wear of both cutting edges of the cutters.
