At present, a turnover plate is arranged at the position of a rear connecting rod to realize the coal cleaning effect, but the turnover plate structure is fixed on the rear connecting rod of the hydraulic support, so that a part of valve group and hydraulic pipeline space can be influenced, and displacement is required; and can not effectively clean according to the number of accumulated coal in a layered way, and when the amount of coal is too large, the overturning plate can be blocked.
This patent adopts pushing away the shovel and transversely pushes away the structure realization clear coal, through reserving articulated ear seat and pivot at hydraulic support rear portion and both sides, with this patent clear coal device is connected. The slide rail beam is hinged with the rotating shafts on two sides of the hydraulic support base, can swing up and down, one side of the slide rail beam is connected with the pushing shovel pin shaft, and the other side of the slide rail beam is in sliding fit with the slide rail beam. The slide rail beam, the sliding beam, the transverse pushing jack and the swinging jack form a crank sliding block mechanism, the transverse pushing jack pushes the pushing shovel to push and clear coal, the swinging jack can drive the coal clearing device to swing up and down to throw the float coal into the chute of the rear scraper conveyor, the coal clearing function is realized, and the labor intensity of workers can be effectively reduced.
Disclosure of Invention
In view of the above, the utility model aims to overcome the defects in the prior art, and provides the transverse pushing type coal cleaning device at the rear part of the hydraulic support for caving the top coal, which can realize the function of cleaning the coal at the rear part, effectively reduce the labor intensity of workers and reduce the efficiency of people.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the coal cleaning mechanism comprises a push shovel, a transverse pushing jack and a sliding guide assembly which are respectively arranged at two sides of the rear part of the push shovel, and a swinging jack arranged on the sliding guide assembly; the other ends of the transverse pushing jack and the swinging jack are fixed with the hydraulic support base through pin shafts, and the installation height of the swinging jack is higher than that of the transverse pushing jack; the other end of the sliding guide assembly is hinged with rotating shafts on two sides of the hydraulic support base, and is fixed and limited by a compression nut.
Aiming at the technical scheme, the sliding guide assembly, the transverse pushing jack and the swinging jack form a crank block mechanism, so that the normal lowering, moving and other actions of the hydraulic support are not influenced; the transverse pushing jack and the pushing shovel form a transverse pushing structure to realize coal cleaning, and at the moment, the slideway beam and the sliding beam play a guiding role; on the one hand, the swinging jack can adjust the angle of the push shovel during horizontal pushing to avoid the push shovel from penetrating too deeply, on the other hand, the push shovel can swing up and down through the adjustment of the swinging jack, float coal is thrown into a chute of a rear scraper conveyor, the coal cleaning function is realized, and the labor intensity of workers can be effectively reduced.
Preferably, the sliding guide assembly comprises a horizontally arranged slideway beam and a sliding beam in sliding connection with the slideway beam.
Preferably, a pressing plate is arranged on the outer side of the compression nut. Preventing the compression nut from unscrewing.
The beneficial effects of the utility model are as follows:
the utility model adopts a horizontal pushing shovel structure, the horizontal pushing jack is arranged near horizontally, the pushing force is large, the coal cleaning capability is strong, meanwhile, the device is only connected with the base of the hydraulic support, and the slideway beam, the sliding beam, the horizontal pushing jack and the swinging jack form a crank slide block mechanism, so that the normal lowering, moving and other actions of the hydraulic support are not influenced; the horizontal pushing jack pushes the pushing shovel to push and clean coal, the swinging jack can drive the coal cleaning device to swing up and down to throw the float coal into the chute of the rear scraper conveyor, the coal cleaning function is realized, and the labor intensity of workers can be effectively reduced.
