Wherein interior protecting jacket is fixing by screw A and piston rod cover, outer protecting jacket is fixed by screw B and bearing seat, between interior protecting jacket and outer protecting jacket, leave gap, the telescoping protecting jacket is placed in inside and outside protecting jacket inside, and telescoping protecting jacket up and down two ends is fixed with piston rod cover and bearing seat respectively by screw C.
Wherein pull bar is connected by pin B with coal-pushing plate, and scraper plate and pull bar are bolted.
When the hydraulic actuating cylinder underlying, anti-pounding on seat fixed and be arranged on to minute coal cover and pull bar by welding manner; When on hydraulic actuating cylinder, putting, minute coal cover is fixed with the anti-seat of pounding by screw D.
The utility model compared with prior art has following beneficial effect:
1, piston rod cover, anti-seat, minute coal cover common guarantee hydraulic actuating cylinder and the piston rod pounded can not be subject to the impact of coal and the intrusion of coal grain, have guaranteed the good environment for use of hydraulic actuating cylinder, the service life of having improved loosening machine.
2, piston rod is connected by oscillating bearing with pull bar, prevents piston rod bending or piston wear aggravation, has guaranteed the service life of loosening machine.
3, oscillating bearing and bearing seat are placed in protecting jacket and telescoping protecting jacket inside, prevent coal intrusion oscillating bearing inside, have guaranteed the normal use of oscillating bearing.
4, coal-pushing plate adopts expansible formula structure, pushes away the loose area of coal process large, and coal-pushing plate closure during return, greatly reduced return power, thereby reduce hydraulic system working pressure, extends the loosening machine life-span.
5, on pull bar, scraper plate is installed, the linear reciprocating motion of scraper plate will constantly be removed the coal seam that bonds on the coal bunker wall, thereby can effectively avoid the coal bunker leak to dwindle or the appearance of latch up phenomenon.
