Description

The invention relates to hydromechanization. The goal is to increase the efficiency of the development of the soil by expanding the range of the device from one, dredger parking. The intake device of the suction dredge includes the housing 1 and the suction pipe (W) 3 placed on the frame 2. The latter is connected to the suction pipe of the ground pump by means of a ball joint. He you-

The invention relates to hydromechanization.

The purpose of the invention is to increase the efficiency of the development of the soil due to the expansion of the range of the device from a single dredger station.

Figure 1 shows the soil-collecting device 25 suction projectile, side view; figure 2 - the same, front view.

The soil-collecting device of the ground-pine shell consists of a body 30 1, a frame 2 of a soil-collecting device with a suction pipe 3 placed on it, a ball joint consisting of a stationary 4 and a movable 5 hemispheres, a bracket 6, with one end hinged on a stationary hemisphere 4, another the hinge end is on the moving hemisphere 5, the trunnions of 7 g on the stationary hemisphere 4, the trunnions 8 on the moving hemisphere 5, 49

hydraulic cylinders 9 connecting the bracket 6 with the housing 1, the suction tip 10, hydraulic cylinders 11 for the implementation of the telescopic movement of the tip 10. The remaining symbols are 45 accepted: ground pump 12; drive 13 suction dredger; pressure pipe 14; hydraulic cylinder 15 for lateral movement of the suction pipe; soil 16 in the face; water area 17 face.

Suction dredge is used as follows.

The frame 2 of the soil collecting device is lowered into the water area 17 of the face. At 55 this, the rods of the hydraulic cylinders 11 are retracted. ”The suction pipe and the suction tip are filled with water. Included in the work of dredger 12. In

the suction pipe 3 is sucked in water, which enters the dredger 12, and from it into the pressure pipe 14. The hydraulic cylinders 11 are activated. Due to the telescopic nature of the connection to the pipeline 3, the suction tip 10 advances, approaches the soil 16. The erosion and suction of the soil begins, which from the tip 10 enters the pipeline 3, into the dredger 12 and the pressure pipeline 14. Gradually extending the tip 10, the soil 16 is developed by the method of funnels.

This method is very effective. They are provided with high productivity of the dredger on the ground plan. Bringing the depth of the suction tip to a value corresponding to the thickness of the soil layer to be developed. Disconnect hydraulic cylinders 11.

Included in the work of the hydraulic cylinders 15 and carry out the rotation of the collecting device to the left. The rotation occurs due to the rotation of the hemispheres of the ball joint. The suction tip 10 papilloses to the left, developing a trench in the soil massif 16. The trench dredging method with a dredger is also very effective, it is on the second place after the funnel method. After the suction tip 10 has reached the extreme left position, the hydraulic cylinder 9 is moved in, pulling the clamp 6. The suction pipe 3 is rotated in a spherical hinge in a vertical plane. The suction tip moves forward (Fig. 1), scored 5

developed trench. The work of the hydraulic cylinders 11 push the tip 10 to the level of the bottom of the trench.

Hydraulic cylinders are turned on. 15 th turn the suction pipe. 10 wire from left to right. At the same time, the soil is developed by papilonazhny method, which provides for the normal typical work of a dredger of the construction type. After reaching the suction tip of the extreme right position, move the tip forward, install its mouth at the level of the bottom of the excavation and work with penetration from right to left. 20

After excavation from the soil massif, 16 parts of the soil within reach according to the conditions of the telescopic extension of the tip 10 are pushed into the suction pipe 25 3. The dredge is pushed forward, its position in the bottom is fixed with the help of piles or anchors. The suction tip is buried in the soil massif by the method of funnels and, in accordance with this description, the area adjacent to the developed one is developed. Periodic movements of the dredger develop the soil in the face.

In the proposed device vsasy- 35

the tip has the ability to move in any direction due to the telescopicity of its connection to the suction pipe and the supply of a bracket 6, trunnions 7 and 8, and 40 also hydraulic cylinders 9,11 and 15; due to the possibility of turning the suction pipe in mutually perpendicular directions and the telescopic nature of the suction pipe connection 45

finisher, it is possible to develop the soil at a given depth with high completeness and efficiency (using a combination of all three methods: funnels, trench and papilonazhny).
