Abstract
The utility model discloses a crusher for smoothening a chute in a coalmine pit, which comprises a crushing chamber, as well as a hydraulic system and a crushing assembly. The crushing assembly comprises a hydraulic suspension arm and a hydraulic crusher which are interconnected; and the hydraulic system is respectively connected with the hydraulic suspension arm and the hydraulic crusher. The hydraulic suspension arm is mounted on a hydraulic revolution assembly; and a baffle grid plate is arranged in the crushing chamber. The crushing chamber is mounted on a crushing bottom groove; due to an oil cylinder on an operating suspension arm, the hydraulic crusher is accurately positioned on coals and waste rocks to be crushed, and then the pick drill of the hydraulic crusher is operated to reciprocate up and down so as to impact and crush large-block coals and waste rocks. The crusher adopts full-hydraulic operations, has a stable hydraulic system, is convenient to operate, and accurate and reliable to position; and the operation mode of the crusher is intermittent, crushing can be timely carried out according to the coals and the waste rocks blocked in the chute of a conveyer. Compared with a hammer type crusher, the crusher has small power, has no need to continuously operate, and is very suitable for a pit with soft coals and less waste rocks.
Description
Technical field
The utility model relates to plant equipment under the coal mine, the coal that particularly a kind of middle and small scale coal mine uses and the disintegrating apparatus of spoil.
Background technology
When middle-size and small-size mine adopts full-seam mining to put outer coal winning technology in adopting, need suitable working face disintegrating machine and the supporting use of elevating conveyor, and with supporting belt feeder, working face scraper plate machine, galianconism coal-winning machine and hydraulic support supporting operation, realize comprehensive mechanical coal mining and fragmentation, transport.And present disintegrating machine is the hammer mill of belt pulley transmission, operation continuously behind the starting up, and also power is big, is not suitable for middle-size and small-size mine and uses.
Summary of the invention
The utility model must connect operation and high-power problem for what the hammer mill that solves the existing wheeled transmission of belt existed, and a kind of coal mine downhole crossheading disintegrating machine is provided.
For addressing the above problem, the technical solution adopted in the utility model is: a kind of coal mine downhole crossheading disintegrating machine, comprise broken cavity, also comprise hydraulic system and broken assembly, broken assembly comprises continuous hydraulic arm and hydraulic burster, and hydraulic system is connected with hydraulic burster with hydraulic arm respectively.
During use, broken cavity is installed on the broken kerve, the oil cylinder on the manipulation cantilever is accurately positioned in hydraulic burster and treats on broken coal, the spoil that the original text pricker of operating hydraulically operated destroyer pumps then, realize the impact grinding to coarse coal, spoil.
Coal mine downhole crossheading described in the utility model adopts all-hydraulic operation with crusher, and hydraulic system is stable, and easy to operate, accurate positioning is reliable; The disintegrating machine working method is a service intermittent, according to being carried out in good time fragmentation by the situation of retaining coal, spoil in the elevating conveyor chute.Compare with hammer mill, power is little, and does not need continuous operation, is fit to very much the mine that ature of coal is soft, spoil is few and uses.
