SU1339209A1 - Soil intake device of suction dredger - Google Patents

Abstract

The invention relates to the construction and increases the efficiency of the development of soils with oversized inclusions. The device includes a tip 1 with internal 4 and external 5 grids (P). P4 and 5 are attached to the tip 1 by means of QiapHHpa 6, and P 4 is fixed on the hinge 6 of the outer P 5. When they get into P 4 and 5, oversized inclusions are cleaned. For this purpose, the hydraulic cylinder 2 is turned on. When the stem 3 of the hydraulic cylinders 2 P 4 and 5 are extended, they jointly separate from each other, turn on the hinge 6. Due to the further extension of the stem 3, the P 5 rotates and the P 4 and 5 are cleaned from oversize. Both R 4 and 5 m. mounted to move them from the suction tip 1 by means of an additional drive.

with a foot of water, the particles are oversized. with sizes larger than the passage section 1Н1Я i | iyiiT () Boro pump. They strike the ribs on the ribs of the spindle 4, 5 and fall to the bottom of the bottom.

An external lattice 4 is pivotally attached to the rods 3, the rods through the lattice 4 are freely spaced in the noses of the lattice 4 (the grooves are not shown).

During cleaning, hydropilins 2 are put into operation. The rods 3 move out of the hydraulic cylinders 2. The reamers 4 and 5 jointly, apart from each other, move away from the mouth of the suction tip to the distance T | (Fig. 5). At this distance, the speed of the water flow sucked into tip 1 is not enough to carry oversize dimensions into the tip of soil particles. With a clearance between tip 1 and gratings 4 and 5, equal to T |, the chain 9 is stretched to its full length. Upon further extension by the rod 3, the rip 10 bends, the reel 5 separates from the grill 4 and moves away from the tip to the distance T (Fig. 6).

The openings formed by the grids 4 and 5 are enlarged, the clamping of the over-sized particles in the grids is eliminated. Oversize falls out of the gratings and fall to the bottom of the developed part of the bottom.

The hydraulic cylinders 2 are activated. The rods 3 are pushed into the hydraulic cylinders 2, the lattice 5 is mixed in the direction of the suction tip 1. The lattice 5 is at a distance T | From the tip, a slider 4 is superimposed, and a stop 10 closes the grids. Rep1 4, 5 together inseparably
