Embodiment Construction
[0015] Carry out the specific embodiment of the present invention in detail below in conjunction with accompanying drawing:
[0016] Such as Figure 1-3 As shown, a transition tank with the function of bulk coal pre-crushing includes a transition tank body 6, a transition baffle plate 1, a crushing frame body 3, a hydraulic cylinder 4, and a crushing drum 5. The transition tank body 6 is provided with a connecting ear C , the connecting ear D and the connecting plate 2, the connecting ear C, the connecting ear D and the connecting plate (2) and the transition tank body (6) are welded integral structures, and are located on the same side as the transition baffle 1, and the crushing frame body 3 passes through The pin 7 is hinged to the connecting lug C on the transition tank body 6, and the hinge point is located at the beginning section A of the transition tank, which is at a lower position of the transition tank, so that the maximum height S of the crushing drum is smaller, a...

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: [0001] The invention relates to the field of scraper conveyors for fully mechanized mining working faces in coal mines, in particular to a transition tank and a scraper conveyor with the function of pre-crushing bulk coal. Background technique: [0002] In the fully mechanized mining face of the coal mine, due to the comprehensive influence of periodic pressure and mining disturbance, large pieces of coal on the working face collapse periodically, and even collapse in pieces in severe cases. Large pieces of coal falling into the conveyor chute not only affect the normal transportation of the coal flow, but also when it reaches the conveyor head, it is difficult to unload at the unloading point of the conveyor, even if it is unloaded to the reloader, it is difficult to enter the reloader entry point In the box-type conveying tank at the place, it is easy to cause serious blockage at the head of the conveyor, and even be forced to stop. At present, the proces...
