2. Main uses and scope of application
The mining hydraulic pusher is a double-acting hydraulic mechanism with internal liquid. It can realize the movement of blast mining working face or general mechanical mining working face and scraper conveyor in underground coal mines. If parts such as the base are replaced, it can also be used to move the plow. In addition, merchants can complete the recovery work of the pillars of the coal mining face. It is suitable for coal mining faces with medium-thick coal seams and supported by external injection single hydraulic pillars.
3. Mining use
Hydraulic pusher
Performance characteristics: large thrust, light weight, high bending strength, smooth movement, reliable sealing, and easy maintenance.
Usage Scope: Moving the conveyor on blast mining working face or general mechanical mining working face
Main parameters
//~/~/~//

Pusher The structure of the pusher is mainly composed of the control valve (valve cover, valve body, fork, handle, etc.) cylinder, piston rod, piston ring check valve, support seat, and other components. Its liquid supply system and The external injection single hydraulic prop shares a set of pump stations and liquid injection guns, and the return liquid is discharged to the coal mining face.
.
Working Principle
The high-pressure liquid from the hydraulic pump station enters the cavity of the valve cover through the high-pressure infusion pipeline and injection gun. At this time, the push button can be pushed by pulling the handle. The reciprocating motion of the slider.
.
How to use the pusher
.
Use an external injection single hydraulic prop between the support base of the pusher and the working top plate to tighten the support to push the slide. device fixed.
.
First move the handle to the push position, then connect the liquid injection gun to the one-way valve on the valve cover, and pull the trigger of the liquid injection gun. Extend the piston rod and push the conveyor close to the coal wall.
.
Unload and remove the external injection single hydraulic prop that fixes the support base.
.
Pull the handle to the retracted position and pull the trigger of the liquid injection gun to retract the piston rod. Pull back the cylinder of the pusher together with the support. Completed a coal conveyor move.

Precautions for installation and use of pusher
．
The number of layouts on the working surface can be determined according to the scraper model, laying length and working slurry mixing. On the working surface of the use-type scraper, install one every meter
. On the working surface of the scraper machine, install one every meter
For example, when using the scraper conveyor supporting the drum shearer, in order to move the shearer and the scraper conveyor together, the number of pushers can be added at the conveyor head and tail as appropriate.
．
The pusher and the scraper conveyor baffle are connected with a two-way joint and a pin.
