Description

Technical Field

[0001] This utility model belongs to the technical field of vibrating screen feed chute, and in particular relates to an anti-blocking device at the outlet of a vibrating screen feed chute. Background Technology

[0002] Coal is a solid combustible organic rock, mainly formed by the underground deposition of ancient plant remains through biochemical and geological processes. In ancient times, large amounts of plants accumulated in wetland environments such as swamps. Over a long period of time, the plant remains gradually lost moisture and volatiles under the decomposition of microorganisms, while undergoing complex physical and chemical changes under high temperature and high pressure geological conditions.

[0003] After coal mining, a vibrating screen is used to screen and crush the raw coal. Typically, the raw coal first flows into a feed chute, and then, under the chute's compression, flows into the vibrating screen. To prevent blockage at the feed chute outlet during the coal collection and transport process, an anti-blocking device for the feed chute outlet of the vibrating screen is designed. This device adds a U-shaped support and inclined vertical plate to the inner cavity of the feed chute, allowing the U-shaped support and inclined vertical plate to reciprocate linearly. This loosens the coal within the feed chute, preventing blockage at the feed chute outlet during coal collection and transport. Utility Model Content

[0004] The purpose of this invention is to provide an anti-blocking device at the outlet of a vibrating screen feed chute, which aims to prevent blockage at the outlet of the feed chute when raw coal is collected and transported, thereby solving the aforementioned technical problems.

[0006] Preferably, the inner cavity of the hollow rectangular block is threadedly connected to the surface of the carbon steel bidirectional threaded rod, and the front and rear sides of the U-shaped bracket are slidably connected to the inner cavities of the two sliding grooves respectively.

[0007] Preferably, the left end of the carbon steel bidirectional threaded rod is fixedly connected to a pulley by bolts, and the left side of the feed chute is fixedly connected to a motor by bolts.

The device includes: a hollow support frame 2 bolted to the inner cavity of the feed chute 1; grooves on both the front and rear sides of the hollow support frame 2; a protective frame 3 welded to the top of the hollow support frame 2; a carbon steel bidirectional threaded rod 4 rotatably connected to the rear side of the inner cavity of the protective frame 3; the surface of the carbon steel bidirectional threaded rod 4 coated with a galvanized layer; a guide rod 5 bolted to the front side of the inner cavity of the protective frame 3; two hollow rectangular blocks 6 slidably connected to the surfaces of the carbon steel bidirectional threaded rod 4 and the guide rod 5; a U-shaped bracket 7 bolted to the bottom of the two hollow rectangular blocks 6; and a welded top to the U-shaped bracket 7. Two inclined vertical plates 8 are connected. The inner cavity of the hollow rectangular block 6 is threadedly connected to the surface of the carbon steel bidirectional threaded rod 4. The front and rear sides of the U-shaped bracket 7 are slidably connected to the inner cavities of the two chutes respectively. The left end of the carbon steel bidirectional threaded rod 4 is fixedly connected to a pulley 9 by bolts. The left side of the feed chute 1 is fixedly connected to a motor 10 by bolts. The front and rear sides of the inner cavity of the U-shaped bracket 7 are fixedly connected to triangular reinforcement members 14 by bolts. By setting the triangular reinforcement members 14, the U-shaped bracket 7 can be made more robust at the bends when it supports the inclined vertical plates 8 to loosen the coal in the inner cavity of the feed chute 1 during the sliding process of the U-shaped bracket 7 in the inner cavity of the feed chute 1.

[0026] Example 2:

[0027] Figure 1-5This invention illustrates an anti-clogging device at the outlet of a vibrating screen feed chute according to an embodiment of the present invention. The device includes: a hollow support frame 2 bolted to the inner cavity of the feed chute 1; grooves on both the front and rear sides of the hollow support frame 2; a protective frame 3 welded to the top of the hollow support frame 2; a carbon steel bidirectional threaded rod 4 rotatably connected to the rear side of the inner cavity of the protective frame 3; the surface of the carbon steel bidirectional threaded rod 4 coated with a galvanized layer; a guide rod 5 bolted to the front side of the inner cavity of the protective frame 3; two hollow rectangular blocks 6 slidably connected to the surfaces of the carbon steel bidirectional threaded rod 4 and the guide rod 5; a U-shaped bracket 7 bolted to the bottom of the two hollow rectangular blocks 6; and a welded top to the U-shaped bracket 7. Two inclined vertical plates 8, the output shaft of motor 10 passes through the inner cavity of protective frame 3, and is fixedly connected to pulley 11 by flange. The surfaces of pulley 19 and pulley 11 are connected to belt 12 for transmission. A limiting ring 13 is welded at the center of the surface of guide rod 5. The top of protective frame 3 is fixedly connected to feed guide groove 15 by bolts. Feed guide groove 15 is fixedly connected to the inner wall of feed chute 1 by bolts. By setting feed guide groove 15, coal can be guided and assisted in gathering when entering the inner cavity of feed chute 1, so that coal can flow more smoothly into the inner cavity of feed chute 1, and the top of protective frame 3 and coal are protected.

[0028] Working principle: When using this utility model, the user starts the motor 10 to drive the pulley 11 to rotate. At this time, under the transmission action of the belt 12, the pulley 11 drives the pulley 9 to rotate. When the pulley 9 rotates, it drives the carbon steel double-threaded rod 4 to rotate. At this time, the guiding and limiting function of the guide rod 5 can cause the hollow rectangular block 6 on the surface of the carbon steel double-threaded rod 4 and the guide rod 5 to slide the U-shaped bracket 7. Then, under the action of the carbon steel double-threaded rod 4, the U-shaped bracket 7 and the inclined vertical plate 8 slide back and forth. This causes the inclined vertical plate 8 to slide and loosen the coal in the inner cavity of the feed chute 1, thus preventing blockage at the outlet of the feed chute when the raw coal is collected and transported.

[0029] In summary, the anti-blocking device at the outlet of the vibrating screen feed chute works by starting the motor 10 to drive the carbon steel bidirectional threaded rod 4 to rotate, which in turn drives the U-shaped bracket 7 and the inclined vertical plate 8 to slide back and forth in the inner cavity of the feed chute 1. This causes the inclined vertical plate 8 to slide and loosen the coal in the inner cavity of the feed chute 1, thus preventing blockage at the outlet of the feed chute when the raw coal is collected and transported.
