Detailed Description
The present application is described in further detail below with reference to figures 1-3.
The embodiment of the application discloses stifled device is prevented to broken arch for coal feeder. As shown in figure 1, the arch breaking and anti-blocking device for the coal feeder comprises a hydraulic cylinder 2 which is pre-installed on the ground, wherein a piston rod of the hydraulic cylinder 2 extends upwards in an inclined mode into a feed hopper 1 and is provided with an arch breaking sleeve 21 which penetrates through the feed hopper 1 in a sliding mode. After the materials are arched in the feed hopper 1, the hydraulic cylinder 2 can drive the arch breaking sleeve 21 to move upwards in the feed hopper 1 in an inclined mode, so that the arched materials are pushed open, the arched materials are convenient to clean, the labor intensity of workers is reduced, and the production efficiency is improved.
As shown in fig. 1 to 3, the side of the feeding hopper 1 is provided with a through hole 11, a sealing ring 12 is fixedly embedded in the through hole 11, and the arch breaking sleeve 21 is slidably embedded in the sealing ring 12, so that the sealing ring 12 can be more closely attached to the outer wall of the arch breaking sleeve 21, and the material in the feeding hopper 1 is not easily taken out by the arch breaking sleeve 21.
It is worth to be noted that the cylinder body of the hydraulic cylinder 2 is slidably embedded in the arch breaking sleeve 21, so that when the hydraulic cylinder 2 drives the arch breaking sleeve 21 to move and reset, the material brought out of the feed hopper 1 by the arch breaking sleeve 21 is not easy to attach to the hydraulic cylinder 2.
The outside of feeder hopper 1 is connected with clearance ring 3 through connecting rod 31, and broken cover 21 slides to inlay and establishes in clearance ring 3, and a plurality of broken teeth 32 are installed towards the one end of feeder hopper 1 to clearance ring 3. At broken cover 21 slip in-process that resets, broken tooth 32 can carry out the breakage to the material that adheres to on broken cover 21 outer wall, and the clearance ring can block the material that is taken out feeder hopper 1 by broken cover 21, has made things convenient for the clearance of material to make the material be difficult for adhering to on the cylinder body of pneumatic cylinder 2.
It should be noted that the height of the upper surface of the material guiding plate 4 is gradually reduced from the edge to the center, so that the material on the material guiding plate 4 is not easy to fall off from the edge of the material guiding plate 4 in the process of sliding down.
Two slide rails 5 that are vertical setting are installed in the outside of feeder hopper 1, and sliding fit has same door 6 that opens and shuts on two slide rails 5, at the in-process of feeder hopper 1 feeding, opens and shuts door 6 and seals the gliding in retrieving material mouth 13 for the raise dust that produces in the feeder hopper 1 is difficult for wafting out outside feeder hopper 1 from retrieving material mouth 13.
The implementation principle of the arch breaking and anti-blocking device for the coal feeder in the embodiment of the application is as follows: after the materials are arched in the feed hopper 1, the hydraulic cylinder 2 can drive the arch breaking sleeve 21 to move upwards in the feed hopper 1 in an inclined mode, so that the arched materials are pushed open, the arched materials are convenient to clean, the labor intensity of workers is reduced, and the production efficiency is improved.
When the arch breaking sleeve 21 moves to reset, the sealing ring 12 is tightly attached to the outer wall of the arch breaking sleeve 21, so that the material in the feed hopper 1 is not easily taken out by the arch breaking sleeve 21; a small amount of materials brought out of the feed hopper 1 by the arch breaking sleeve 21 are firstly broken by the breaking teeth 32, then are blocked by the cleaning ring 3 and fall on the material guide plate 4, and then enter the feed hopper 1 again through the material guide plate 4 and the recovery port 13, so that the recycling of the materials is realized.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
