Abstract
The invention relates to the field of scraper conveyers of underground coal minefully mechanized coal mining faces, in particular to a ramp pan with a large coal precrushing function and a scraper conveyer. The problem that the unloading portion of a conveyer head is blocked by large coal is solved. The ramp pan comprises a ramp pan body, a transition baffle, a crushing frame, a hydraulic cylinder and a crushing roller. The ramp pan body is provided with a connecting lug C, a connecting lug D and a connecting plate. The crushing frame is hinged to the connecting lug C on the ramp pan body through a pin, and the hinge point is located at the climbing initial segment A of the ramp pan. One end of the hydraulic cylinder is hinged to the crushing frame, and the other end of the hydraulic cylinder is hinged to the connecting lug D on the ramp pan body. The crushing roller and the crushing frame are of a welded integrated structure. The ramp pan is compact in structure and convenient to mount, the overall equipment height is small, three-machine matching is facilitated, the labor intensity and unsafe factors of manually crushing and removing large coal are reduced, and continuous mining of the fully mechanized coal mining faces is facilitated.
Description
Technical field:
The present invention relates to underground coal mine fully-mechanized mining working surface conveyer field, specifically a kind of transitional slot and slat conveyer with coarse coal precrushing function.
Background technology:
At underground coal mine fully-mechanized mining working, by periodic weighting and the combined influence exploiting disturbance, driving surface wall caving coarse coal is periodically caving, and even can be caving in flakes time serious.Coarse coal falls into the normal transport that conveyer chute not only affects coal stream; and when arriving conveyer head place; be difficult to unload at conveyer unloading point; even if be unloaded on elevating conveyor; also be difficult to enter in the box conveying cell body at elevating conveyor entrance place; easily cause conveyer head position Severe blockage, even by forced-stopping machine.At present, after fully-mechanized mining working process coarse coal is shut down mainly through load transfer device, by hand breaking, cleaning coarse coal, open continually, shut down the continuous exploitation not only affecting driving surface, and add the labour intensity of workman; Especially under stopped status; transport is in halted state; if meet wall caving coal to be caving in a large number; be easy to cause conveyer chute be crushed to death and cannot restart; virtually add the work capacity that driving surface manually breaks coal and clear coal, have a strong impact on the production efficiency of driving surface, further increase potential safety hazard; be unfavorable for that colliery realizes safety, exploits high-yield and high-efficiency, solving coarse coal Crushing Problem is fully-mechanized mining working a great problem urgently to be resolved hurrily.
Summary of the invention:
The object of the present invention is to provide a kind of transitional slot with coarse coal precrushing function, solve the problem of conveyer head position coarse coal blocking.
Another object of the present invention is to provide a kind of slat conveyer, its transitional slot has coarse coal precrushing function, before coarse coal enters head unloading point, it is broken, avoids coarse coal plugging machine head position, ensures the normal conveying of coal stream.
The technical solution used in the present invention is: a kind of transitional slot with coarse coal precrushing function, comprise transition cell body 6, transition baffle plate 1, broken support body 3, hydraulic actuating cylinder 4, crushing roller 5, transition cell body 6 is provided with and connects ear C, connection ear D and gusset piece 2, broken support body 3 by pin 7 with on transition cell body 6 to connect ear C hinged, hinge-point is positioned at transitional slot climbing the initial segment A place, hydraulic actuating cylinder 4 one end and broken support body 3 hinged, the other end with on transition cell body 6 to connect ear D hinged, crushing roller 5 and broken support body 3 are welded formula structure.
Further, connecting ear C, connecting ear D and gusset piece 2 and transition cell body 6 is welded formula structure, and is all positioned at the baffle plate side of transition cell body 6.
To achieve these goals, present invention also offers a kind of slat conveyer, be provided with above-mentioned a kind of transitional slot with coarse coal precrushing function.
The transitional slot that the present invention relates to has coarse coal precrushing function, before coarse coal enters head unloading point, it is broken, avoid coarse coal plugging machine head position, ensure that the unimpeded of conveyer " throat " position, broken frame hinge-point is positioned at transitional slot climbing the initial segment A place, installation site is lower, workman is easy for installation, also make crushing roller maximum height S obtain minimum value simultaneously, even if in high working face thick coal-layer mining, crushing roller maximum height S also only has about 3 meters, and the entirety not affecting three machines is supporting.
This apparatus structure is compact, simple to operate, achieve the breaking size continuously adjustabe of coal, contribute to fully-mechanized mining working and realize exploitation continuously, reduce labour intensity and the safety hazard of hand breaking coarse coal, effectively meet the demand that fast freight is adopted soon soon pushed away to coal mine fully-mechanized mining working.
