Description

Technical Field

[0001] The utility model relates to the technical field of coal mining, in particular to a dust cover for a transfer machine used in coal mining. Background Art

[0002] As we all know, the full name of the transfer machine is the scraper transfer machine for the chute. It is a bridge-type scraper conveyor installed in the section transport level tunnel at the exit below the working face of the mine. When the transfer machine is working, one end is overlapped with the conveyor on the working face, and the other end is connected to the tail of the belt conveyor. Its role in the three-machine matching of large-scale comprehensive mining technology is to transfer the coal transported by the scraper on the mining face to the belt conveyor after it is raised from the bottom plate of the tunnel.

[0003] In order to prevent the coal dust raised during transportation from harming the health of workers, the existing technology usually installs a dust cover on the transfer machine; however, since the existing dust cover is mainly fixed to the transfer machine by tightening multiple bolts in sequence, the disassembly and assembly process is relatively laborious, and the work efficiency of the dust cover during installation and replacement still needs to be improved; for this reason, we propose a dust cover for a transfer machine used in coal mine exploitation.

[0004] The above information disclosed in the Background section is only for enhancement of understanding of the background of the present disclosure and therefore it may include information that does not constitute the prior art that is already known to one of ordinary skill in the art.

The bottom of the connecting block is fixedly connected to a rod body, and a slot is provided on one side of the outer wall of the rod body. Connecting rods are fixedly connected to both sides of the support block. An insertion rod for inserting into the slot is movably mounted on the connecting rod. A first spring is mounted on the connecting rod. The two ends of the first spring are respectively fixedly connected to the insertion rod and the support block. A ring body is fixedly mounted on the insertion rod, and a movable baffle for pressing against the ring body is slidably connected inside the support plate.

[0008] By adopting the above technical solution, when the dust cover body is installed on the coal mine transfer machine bracket, the dust cover body can be firstly sleeved on the outer side of the coal mine transfer machine bracket, so that the connecting block can drive the rod body to squeeze the insertion rod, and then the squeezed insertion rod can slide on the connecting rod, and the tensioning force of the first spring can drive the insertion block to be inserted into the slot to position the rod body, so that the dust cover body can be quickly and stably installed on the transfer machine bracket; in addition, when disassembling, the insertion rod can be pulled out of the slot by pulling the ring body, and then the ring body can be tightened by pushing the movable baffle upwards, so that the insertion rod after moving out of the slot can be limited, thereby facilitating the removal of the dust cover body from the transfer machine bracket.

[0009] Preferably, a slide groove is provided inside the insertion rod, and a slider is slidably connected to the inner side wall of the slide groove, and one side of the slider is fixedly connected to the connecting rod.

[0010] By adopting the above technical solution, the insertion rod can be kept stable when moving.

[0011] Preferably, a handle is fixedly connected to the outer side of the ring body.

[0012] By adopting the above technical solution, it is convenient to pull the ring body, thereby facilitating the pulling of the insertion rod out of the slot.

[0013] Preferably, rubber pads are fixedly connected to both sides of the dust cover body.

[0014] By adopting the above technical solution, the sealing performance of several dust cover bodies after installation can be improved.

[0015] Preferably, a groove for inserting the movable baffle is formed on one side of the ring body.

[0016] By adopting the above technical solution, the movable baffle can be pressed against the ring body more stably.

[0017] Preferably, a stopper is fixedly connected to one side of the movable baffle, a second spring is sleeved on the movable baffle, and two ends of the second spring are respectively fixedly connected to the support plate and the stopper.

[0018] By adopting the above technical solution, after the movable baffle is released, the upward force can be always maintained by the stopper under the resetting action of the second spring.

[0019] Preferably, a pull ear is fixedly connected to one side of the stopper.

[0020] By adopting the above technical solution, it is possible to facilitate pulling the movable baffle through the baffle.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] The coal mine uses a transfer machine dust cover by arranging a disassembly and assembly mechanism on the coal mine transfer machine bracket and the dust cover body, so that after the dust cover body is mounted on the coal mine transfer machine bracket, the insertion rod can be inserted into the slot under the tensioning force of the first spring, so that the rod body can be positioned; through the above arrangement, the dust cover is more labor-saving when being disassembled and assembled, thereby improving the work efficiency of the dust cover during installation and replacement.
