SU118398A1 - Ground Roller Dumper - Google Patents

Description

Wash irrigation to combat soil salinization, as well as rice irrigation, are made by check, limited by rollers (palam). The cutting of the rollers, limiting the checks, is performed by the CSP and KPU-2000A machines, and their leveling is done mainly manually.

Known schemes are mounted on the tractor working body with two and four side dumps for leveling the soil.

The proposed scheme of a mounted, dozer-type, leveling roller of earth rollers is characterized in that, in order to evenly distribute soil over the surface of the floor within the grabber grab, its working body is made of three dumps, of which a short front dump is attached to the frame of the tractor normally to its axis , and two lateral blades are located on it at an angle to each other, close to the direct one, so that their rear ends are somewhat elevated relative to the front ones, as well as the fact that to ensure a steady stroke The frame has two height-adjustable side rollers.

FIG. Figures 1 and 2 show the principle scheme of the mounted graver in two projections.

The mounted land rollers are mounted on the frame of the D-159 bulldozer mounted on a DT-54 tractor and have: two blades 1, symmetrically located near the longitudinal axis of the tractor at an angle to each other, close to 90 °; one blade 2, reinforced in front of two side dumps 1 and installed perpendicular to the direction of movement of the tractor; frame 3 leveler, rear ends hinged to the transverse bar 4 bulldozer D-159. The blades / and 5 are fixed on brackets welded to frame 5, and in the lower part of the blades removable cutting blades are installed along their entire length: knives 5. To ensure a uniform and steady movement along the depth, the mounted leveling device has two support rollers 6, which are vertically adjustable by special sector 7. The attachment leveler is controlled from the cab of the tractor driver with the help of the hydraulic system 8, which is fully used after the removal of the bulldozer. There are two brackets 9 for connecting the rods of the lifting cylinders with the frame on it.

No. 118398-2 -

At the beginning of work, the leveler is directed along the roller, its front blade cuts the roller with its knife and, loosening, lifts it. Upon further movement of the aggregate, the roller is divided into two parts, and the side dumps the soil moves to the sides with a uniform leveling it across the width of the dumps. The rollers are leveled in a single pass of the unit. The unit operates on the I-II transmission of a DT-54 tractor at a speed of 3-4 km / h and is characterized by high productivity.
