Technical Field

[0001] The utility model belongs to the technical field of coal mine transportation, and particularly relates to a liftable coal baffle device. Background Art

[0002] At the coal feeding point of a coal mine belt conveyor, coal blocks are transported to the coal mine belt conveyor through a coal chute, a coal feeder and other coal feeding methods via an upper belt. When the coal blocks fall onto the conveyor belt after passing through a transfer machine, the existing coal baffle only adopts a single plate structure and cannot adjust the coal baffle range according to the actual terrain structure. The coal blocks transported from the transfer machine are likely to cause impact damage and spatter to the conveyor belt and surrounding operators. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a coal mine coal baffle device that is convenient to operate and adjust, so as to solve the problem that the existing device cannot adjust the opening and coal baffle range according to the actual terrain structure.

[0004] The technical solution adopted by the utility model is a liftable coal baffle device fixedly installed at the tail of a transfer machine, which includes a first coal baffle and a second coal baffle arranged vertically and overlappingly. A chute is provided on the back of the first coal baffle, and a slider corresponding to the chute is provided on the front of the second coal baffle. The second coal baffle is slidably connected to the first coal baffle by embedding the slider into the chute; the bottom end of the first coal baffle is fixed on a mounting seat, and the base of a lifting oil cylinder is fixedly connected to the mounting seat. The piston rod of the lifting oil cylinder is connected to the second coal baffle.

[0005] Preferably, the above-mentioned lifting oil cylinder is located on the central axis of the first coal baffle and the second coal baffle, and the piston rod of the lifting oil cylinder is connected to the middle of the back of the second coal baffle through a connecting plate.

[0006] Preferably, there are two groups of corresponding chutes and sliders, which are symmetrically arranged on both sides of the central axis of the first coal baffle and the second coal baffle respectively.

[0007] Preferably, a side baffle is vertically arranged forward on one side of the first coal baffle, and the side baffle is bolted to the first coal baffle.

[0008] Compared with the prior art, the beneficial effect of the utility model is that by setting the first coal baffle and the second coal baffle which are slidably connected, and the second coal baffle can slide up and down along the first coal baffle driven by the lifting oil cylinder, the adjustment of the coal baffle range can be realized according to the actual terrain structure. At the same time, the setting of the side baffle is beneficial to blocking a larger range of coal gangue on the side, thereby further expanding the coal baffle range and solving the problem that the coal blocks transported from the transfer machine are likely to cause impact damage and spatter to the conveyor belt and surrounding operators.

[0011] The following will further explain and illustrate the present utility model in conjunction with the specification drawings for better understanding by those skilled in the art.

[0012] Embodiment 1

[0013] As Figure 1-2 shown, a liftable coal baffle device is fixedly installed at the tail of the conveyor, perpendicular to the longwall conveyor and parallel to the conveyor of the transfer machine, and there is a suitable overlapping distance, which is conducive to discharging. The coal baffle device includes a first coal baffle 1 and a second coal baffle 2 arranged vertically and overlapping. A chute 3 is vertically provided on the back of the first coal baffle 1, and a slider 4 is provided on the front of the second coal baffle 2 corresponding to the chute 3. The second coal baffle 2 is slidably connected to the first coal baffle 1 by the slider 4 being inserted into the chute 3; the bottom end of the first coal baffle 1 is fixed on a mounting seat 5, and fixing small holes are opened on the mounting seat 5. It is fixedly installed at the tail of the loader through bolts passing through the small holes. A base of a lifting oil cylinder 6 is fixedly connected to the rear side of the first coal baffle 1 on the mounting seat 5, and the piston rod of the lifting oil cylinder 6 is connected to the second coal baffle 2.

[0014] By providing the slidably connected first coal baffle 1 and second coal baffle 2, and the second coal baffle 2 can slide up and down along the first coal baffle 1 driven by the lifting oil cylinder 6, the adjustment of the coal baffle range can be realized according to the actual terrain structure, which is beneficial to increasing the coal baffle range and preventing the coal blocks transported from the transfer machine from falling and easily causing impact damage and sputtering to the conveyor belt and the surrounding operating personnel.

[0015] In order to save the power for driving the second coal baffle 2 and ensure sliding in the vertical direction, the above-mentioned lifting oil cylinder 6 is located on the central axis of the first coal baffle 1 and the second coal baffle 2, and the piston rod of the lifting oil cylinder 6 is connected to the middle part of the back of the second coal baffle 7 through a connecting plate 7; there are two groups of corresponding chutes 3 and sliders 4, which are symmetrically arranged on both sides of the central axis of the first coal baffle 1 and the second coal baffle 2 respectively.

[0016] Furthermore, a side baffle 8 is vertically arranged forward on the side surface of the first coal baffle 1, and the side baffle 8 is bolted to the first coal baffle 1. The setting of the side baffle 8 is beneficial to blocking a larger range of coal gangue on the side, thereby further expanding the coal baffle range.

[0017] Usage method: Fix the first coal baffle 1 on the tail of the loader through the mounting seat 5, put the slider 4 of the second coal baffle 2 into the corresponding chute 3, connect the second coal baffle 2 and the connecting plate 7 with bolts, and then connect the side baffle 8 with screws to complete the combined installation of each component of the coal baffle device, and realize controlling the elongation of the lifting oil cylinder according to the actual terrain structure to adjust the coal baffle range of the coal baffle so that it is applicable to different actual environments and roadway height structures.
