Description

The invention relates to the mining industry and is intended for the development of lake salt deposits.

The purpose of the invention is to increase work efficiency by reducing salt loss during excavation.

1 shows a device for the development of lake salt, obsh, i view; figure 2 is the same, top view; fig.Z - working body, a general view; figure 4 is the same, top view; figure 5 is a section aa in figure 2; figure 6 - section bb in figure 2; 7 - end link with a screen; Fig.8 is a section bb In Fig.7; figure 9 - node 1 in Fig.

The device consists of the working body 1, the housing 2, the moving means 3, the hydraulic transport system 4, the pipeline 5. The working body has a milling cutter 6, an actuator 7 and a shaft 8 mounted on the frame 9. The pipeline 5 is also attached to the frame 9. The pipeline 5 has an end a link 10 connected by a vertical hinge 11 to an intermediate link 12 connected by a horizontal hinge 13 to a pipeline 5. At the end link 10 a screen 14 is mounted with a hydraulic cylinder 15. The vertical link deflection mechanism of the end link 10 is made in the form of two hydraulic cylinders 16, akreplennyh via ball joints

17 on the frame 9 and the link 10. The horizontal deflection mechanism of the intermediate link 12 consists of hydraulic gauge 18 connected to the frame and link. The screen 14 bends around the lower part 10 in the lower part and is mounted with the help of the rollers 19 in the guide grooves 20.

The device works as follows. When developing the lower layers of the underwater scarp when there is no danger

breakdown of vacuum in the pipeline 5, the working body 1 operates as a conventional milling intake device. The milling cutter b destroys the formation, mixes the destroyed product with water, and in the form of a slurry it is sucked in by the system 4 hydrotransports. The end 10 and intermediate 12 links represent a continuation of the pipeline.

5, brought to the upper base of the cutter

6. The screen 14 is thrust and does not move the rotation of the cutter 6.

When developing the upper layers of the ledge and its surface part, when there is a danger of vacuum breaking in the pipeline 5, first the end link 10 is installed by means of hydraulic cylinders 16 at an angle to the frame 9 in a vertical plane, and then

the intermediate link 12 is deflected in the direction of rotation of the working member by means of hydraulic cylinders 18. At the same time, the screen extends 14.
