Description

Paste filling hydraulic support

Technical Field

The utility model relates to a coal mining field especially indicates a lotion fills hydraulic support.

Background

With the rapid development of the coal mining industry, the coal pressing problem of 'three times' is becoming more serious, in order to solve the problem, more and more novel filling coal mining supports are developed and put into use, and the sealing problem of the filling area at the rear part of the paste filling support is a main problem influencing the filling efficiency. For how to solve the sealing problem in the filling area, various baffle plate structures exist at present, but most structures adopt the structural form of an upper baffle plate and a lower baffle plate to seal the filling area, so that the structure is complex, and the sealing of the filling area cannot be well realized. This patent therefore proposes a construction in which the filling zone is sealed only by means of an upper baffle.
