Detailed Description
The following is a further description of the specific structure of the present invention:
the utility model relates to a thin coal seam coal mining machine is applicable to the excavation of thin coal seam.
The device structure comprises a coal mining machine 1 provided with a tunneling roller 4 and a sliding bottom plate 2, wherein the coal mining machine 1 is arranged on the sliding bottom plate 2, and the sliding bottom plate is directly placed on the working ground of a mining surface and is dragged to advance through a power system.
The front end perk of slide bottom plate, slide bottom plate 2 can the front end perk both ends be the fillet, and the fillet is established and is made progress the protrusion and establish baffle 3, and baffle 3 overlooks the shape and is the same with the round angle shape of perk. The sliding bottom plate with the raised front end avoids the coal breakage and the coal gangue on the bottom surface from being accumulated in front of the sliding bottom plate, and can effectively push the coal breakage and the coal gangue to two sides to avoid influencing the excavation operation.
The tunneling roller 4 is arranged on the swing arm 5, the swing arm 5 is hinged with the coal mining machine 1, the tunneling roller 4 is located on the side of the coal wall of the coal mining machine 1, a coal dropping plate 6 is arranged in front of the tunneling roller 4 of the coal mining machine 1, the coal dropping plate 6 is fixed on the coal mining machine 1, and the side face of the coal dropping plate 6 is arc-shaped. The rear end of the coal dropping plate 6 is fixed at one end of a rotating arm, the other end of the rotating arm is hinged on the sliding bottom plate 2, and the rotating arm drives the coal dropping plate 6 to rotate to the position above the sliding bottom plate 2 from the front of the tunneling roller 4 through a hydraulic cylinder.
The tunneling roller 4 throws down the coal on the coal wall after the coal is excavated, and because the tunneling roller rotating at a high speed can throw each coal to the front too far, the coal dropping plate is designed to block the thrown coal from falling. Originally, adopt flat-plate coal breakage plate structure, but flat-plate coal breakage plate can lead to the whereabouts position equally too far because the inertia of coal cinder when blockking the coal cinder, and this device has designed the coal breakage plate of arc form, throws the coal breakage plate at the coal breakage on, because the coal breakage plate of arc form, the coal cinder can only be according to the coal breakage plate shape collision backward downwards, has avoided the coal cinder to shed the problem of too far.
The rotating wall that the coal breakage board set up can be with coal breakage board receipts in coal-winning machine front end top, volume when reducing the transportation, collision interference around when reducing the transportation.
In order to timely convey the excavated coal blocks, a transverse scraper conveyor is arranged on the coal mining machine 1 below the tunneling roller 4, and the tunneling roller 4 excavates coal mines, is thrown onto a coal dropping plate 6 and falls into the transverse scraper conveyor. The transverse scraper conveyor is perpendicular to the running direction of the coal mining machine. The tail end of the transverse scraper conveyor is arranged on conveying equipment with the consistent direction of the coal mining machine, and the coal blocks are thoroughly conveyed out along the mining direction.
The limit of a low coal seam leads to the low body of the coal mining machine, and a special dust removal device is needed to effectively improve the environment of a mining site, so that a dust removal nozzle is arranged at the inner side position of the digging roller 4 arranged on the swing arm 5 and connected with a high-pressure dust-settling water pipe. The dust removal nozzles comprise three groups, three dust removal nozzles are fixed on a spray pipe perpendicular to the swing arm 5, and the spray pipe is connected to a high-pressure dust-settling water pipe.
The dust removal nozzle is in the shape of a water mist curtain behind the digging roller, so that dust generated by digging can be effectively controlled around the digging roller 4, and the dust is prevented from being diffused. And dust settling nozzles are arranged on two sides of the transverse scraper conveyor and connected with a dust settling high-pressure water pipe. The dust generated during transportation can be reduced.
The front end of the sliding bottom plate is provided with a warping head and the end part is provided with an arc-shaped bulge, so that the problem that the coal cutter is choked at the front end due to pushing of the fallen coal at the front side of the coal cutter is effectively solved; and a dust fall spraying device is additionally arranged, so that the problem of insufficient dust fall of a thin coal seam coal mining machine is solved.
