Hydraulic movable sieve jig used underground

Abstract

The invention relates to a hydraulic movable sieve jig used underground, comprising a hydraulic movable sieve jig body (2), a conveyer device and a trough (1), wherein the hydraulic movable sieve jig body (2) has an upper end separating chamber (101) for separating out lump coal, a lower end separating chamber (102) for separating out gangue and a sieve plate chamber (103) for separating out fine coal; the conveyer device is used for discharging lump coal and gangue; and the trough (1) has a front chamber (13), a middle chamber (14) and a rear chamber (15) which are respectively communicated with the upper end separating chamber (101), the lower end separating chamber (102) and the sieve plate chamber (103) of the hydraulic movable sieve jig body (2); therefore, the movement stability of the sieve plate is improved, and the requirement on the granularity of the gangue and the lump coal is reduced.

Description

technical field [0001] The invention relates to a hydraulic dynamic screen jig, in particular to a hydraulic dynamic screen jig used in mines. Background technique [0002] As a separation device for gangue and coal, the hydraulic dynamic screen jig is widely used at home and abroad, so the hydraulic dynamic screen jig is an important mining equipment, especially with the green mining of coal mines, it is used in mines It is necessary to sort the coal lumps, sort out the coal gangue and then backfill it into the mine. The dynamic screen jig used in the mine is a new mining equipment. There are two main types of underground jigs: air Type jig, mechanical dynamic screen jig. Because the sieve plate of the air jig machine is fixed in the machine body, the stratification and movement of the material is realized by the compressed air driving the water in the tank, and the movement of the material on the sieve surface from the bottom of the sieve plate upwards through the sieve p...

AI Technical Summary

Problems solved by technology

Its disadvantages are: it needs to be specially equipped with a high-power air compressor, which increases the equipment investment and operators; the effect of layering, moving and loosening of materials is poor, the screening effect is poor, and the efficiency is low

The jigging of the sieve plate of the mechanical moving sieve jigging machine is driven by the motor and the reducer to drive the crank linkage mechanism. The disadvantages are: the mechanical transmission efficiency is low; , by adjusting the length of the pendulum lead screw and changing the pulley, and changing the transmission ratio, it is inconvenient to adjust, and it takes multiple adjustments to achieve a relatively ideal amplitude and frequency, which seriously affects production efficiency, and multiple sets are required. Belts and pulleys increase investment and are not easy to manage

There is no hydraulic dynamic screen jig for underground mines
