Description

one

A self-propelled combine harvester for the construction of slotted drainage is known, which includes a base chassis, a working body, a bunker and a sled.

The purpose of the invention is to eliminate the collapse of the walls of the gap.

For this purpose, the working body is hingedly connected by means of a frame with a bunker located in its immediate vicinity, hingedly suspended on a sled, provided with dumps and ground fillings adjustable in horizontal and vertical planes; the working body is made with travel stops, and the bunker with a movable lid.

FIG. 1 shows a combine with a working body, a general type; in fig. 2 - the same in terms of.

The harvester includes a basic excavator / with a guide frame, designed to hang all the equipment when performing a complex of works on the construction of slotted drains, working body 2 for trench fragments (slit), made in the form of a boom with a uniform chain equipped with cutting elements, working stroke 3 an organ formed as a staple and attached to the guide frame of the excavator; form 4, to which the sled with the bunker is suspended (at the point a, the truss rests on fixed semi-axes, and at point b on the rollers fixed on the working tool); a bunker 5 with a trunk for filling in a trench of filtering material to the desired height; an anvil 6, on which a hopper with a trunk rests by means of horizontal hinges; cover 7 of the trunk of the bunker for adjusting the height of the backfill of filtering material, made movable, dumps 8 and soil fillings 9, located on skids on both sides of the trench symmetrically to its longitudinal axis and adjustable in the horizontal and vertical planes. The work of the combine precedes the layout

slopes of future drainage under the project slope. The construction of the drain starts from its mouth, i.e. from the collector. In this case, the excavator backs up to the edge of the collector and lowers the working body along with the bunker on

one of the slopes of the collector. After 3-5 M fragments of the trench, a dump truck pulls up to the bunker and loads the first portion of the aggregate, which as the excavator advances is poured in an even layer along the bottom

trench In the future, the hopper is periodically filled with filtering material.

The excavated soil is carried to the surface and dumped behind the excavator. Then dumps 8, it shifts to the sides.

For clearing the path of movement of the slide 6. Following the passage of the bunker and filling the required filter layer, the trench is filled with soil by the spreaders 9. To prevent excessive deepening and arbitrary lifting of the tool body relative to the excavator frame, 3 stops are provided. The support rollers of the working body during the operation of the combine are located inside the shackle of these limiters. During the operation of the combine, the bunker rests on a sled, freeing the working body from excessive loads. The working body and the hopper are raised to the transport position using a chain hoist, similar to a serial excavator.

Claims (3)

I. Self-propelled combine for the construction of slotted drainage, including the base chassis, the working body, the bunker and the sled, differ in v4T0, with the aim of eliminating the collapse of the slot walls, the working body is hingedly connected with HELP; frames with a bunker located in its immediate vicinity, hingedly suspended on sleds, equipped with dumps in the horizontal and vertical planes and dumps of soil. 2. Self-propelled Kembine according to claim 1, denounced by the fact that, in order to prevent arbitrary lifting of the working body under the influence of the resistance forces of the ground, the latter is made with travel stops. 3. Self-propelled combine according to claim 1, characterized in that, in order to adjust the height of the backfill of the slot material, the hopper is made with a movable cover.
