: > (,, >The mining hydraulic pusher is a double-acting hydraulic mechanism with internal liquid. It can be realized underground in coal mines
(,, >The movement of blasting mining working face or general mechanical mining working face scraper conveyor. If parts such as the base are replaced, it can also be used to move the coal plow. In addition, the manufacturer can complete the recovery of the pillars of the coal mining working face. Applicable A coal mining face using medium-thick coal seams and supported by external injection single hydraulic props.

: > > The structure of the pusher
><
: > >The pusher is mainly composed of the control valve (valve cover, valve body, fork handle, etc.) cylinder, piston rod, piston ring, one-way valve support seat and other components , its liquid supply system shares a pump station and liquid injection gun with the external injection single hydraulic prop, 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 reciprocating motion of the pusher can be realized by pulling the handle.
><
: > >How to use the pusher
><
: > >Use an external injection single hydraulic prop between the support seat and the working top of the pusher During the period, tighten the pillar to fix the pusher.
><
: >> 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 the liquid injection gun. Extend the piston rod and push the conveyor until it is close to the coal wall.
><
: >> Unload and remove the external injection single hydraulic prop that fixes the support base.
br/> ><
: >> >Pull the handle to the retracted position, pull the trigger of the liquid injection gun, and retract the piston rod. Pull back the cylinder of the pusher together with the support. Complete a coal conveyor The passage of time.
><
: >> Precautions for the installation and use of the pusher
><
: >> The number of arrangements on the working surface can be determined according to the scraper model. It depends on the laying length and working grouting. When using < type working surface, install one piece every < meter. When using < type scraper machine working surface, install one piece 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.
