DEVICE FOR MECHANICAL REMUNERATION OF THE SOIL AND SEPARATION OF THE STONES IN THE CEREMONY OF DRAWN EQUIPMENT

To make possible the development of multi-excavator dredges combined with a reflower, not only light soils (-sand, peat, etc.), but also heavy soils (viscous, solid, stony) | Apply mechanical soil rippers with stone separators .

Distinctive feature

The proposed device is a drum with longitudinal ribs, installed under the ground feeding tray and driven into rapid rotation to break up the clods of soil falling onto it and throw it on the grill to separate the stones. On the schematic drawing fng. 1 shows a front view of an ostrozhtva, and FIG. 2 - side view.

The mechanical soil loosener and stone separator consists of a massive metal drum with several ribs 2, rotated by a dredger motor and two grates: lateral vertical 3 and lower inclined 4 (slope - about 45 °). The ripper is placed in a closed strong

metal casing 5 side extension with a vertical wall of the shift. Post-clodding of lumps of the soil to be loosened occurs through a hole 6 in the wall of this schacht, and for the direction an inclined (about 45 °) shield 7, blocking the sandwiches, serves. When there is no need to use the ripper, this shield, rotated on the horizontal axis by means of the handle 8, located outside the casing, presses against the envelope of the pallet and closes the stroke 6 into the ripper. The lump of soil held by the inclined shield slides toward the ripper and, after passing through its inlet opening, continues to slide along the inclined tray 9 constituting the continuation of the inclined surface of the shield.

The descent from the lower end of the tray, a lump of soil falls on the ribs of the ripper drum, which rotates towards it with great speed. Impact on whom the soil, the edges of the drum split it into small parts and cast them in the direction of the vertical grating .3. Loosened parts of the soil through the intervals, vertical 3,

and partly through the intervals of the bottom 4, the gratings fall into the mine. Large stones 10, which cannot pass through the vertical lattice gaps, are held up by it and fall down on the same inclined grate, on which the side slides or slides. The gaps between the ribs of both gratings should be no larger than the size that is limiting for the stones, the passage w, them through the pump.

So that the stones do not fall past the lattice, the lower inclined lattice has a barrier, its wall on the side of the casing. Those parts of the loosened soil that fall on the lower grid, through its gaps penetrate into the lower part of the room, the ripper, from which the lower opening through the bottom wall of the shaft falls into the mine. Large stones, exit w, not at the bottom reshte and the ripper to the appropriate site, as they accumulate, are periodically diverted to the shore. Since these stones make up an insignificant percentage of the total volume of soil that has been removed, and since they can be used as a building material, their removal does not place a special burden on the development of the soil. When designing a mechanical ripper, all the gaps in the path of large stones should be conformed with the probable size of the stones, remembering that the size of the stones before entering the ripper is limited by the size of the excavator bucket. To enhance the mechanical ripper, its structure can be replenished with several tips of pipes through which the jets supplied from the high-pressure pump begin to loosen the soil before it is processed by the ribs of the bar-aban ripper.

Subject invention

Devices for mechanically loosening the soil and separating stones in the dredger well, for example, using a drum with longitudinal ribs, installed under the ground feeding tray and brought into rapid rotation to break the falling onto it from the ground lumps of soil and discarding them on the grate in order to separate the stones.
