Description

Technical Field

[0001] The utility model relates to the technical field of sampling machines, in particular to a coal sampling anti-blocking chute of a coal sampling machine. Background Art

[0002] The chute installed on the coal sample machine is used to transport coal blocks. Through the inclined chute, after the coal blocks enter the chute, they can slide along the chute under the action of gravity. No external driving source is required to move the coal mine. However, when transporting coal blocks, coal powder is easy to adhere to the chute, inhibiting the normal sliding of the coal blocks.

[0003] A Chinese patent application filed on November 29, 2022, and published as CN219135328U discloses a sampler anti-blocking chute, belonging to the technical field of samplers. The patent comprises a sampler body, a coal sample transfer hopper, and a chute. The lower end face of the chute is provided with a control console, the upper end face of the chute is fixedly connected to a chute receiving hopper assembly, the upper end face of the control console is fixedly connected to a fixed plate, the fixed plate is connected to a first fixed assembly, the first fixed assembly is connected to a blockage-clearing fixed pulley assembly, the blockage-clearing fixed pulley assembly is connected to a wire rope, the wire rope passes through the inner wall end face of the chute, the wire rope is fixedly connected to a blockage-clearing metal block on the inner wall end face of the chute, the wire rope is fixedly connected to a plurality of anti-slip control balls, and the top end face of the chute receiving hopper assembly is connected to a third fixed pulley. The utility model uses the blockage-clearing assembly to prevent the sampler chute from being blocked by sticky coal ash or large coal particles, thereby preventing the normal use of the sampler and improving work efficiency.

[0004] In this technical solution, the coal powder attached to the inside of the chute is cleared out by moving the clearing metal block inside the chute. However, as the distance the clearing metal block moves inside the chute increases, the amount of coal powder accumulated in front of the clearing metal block increases and mixes with part of the coal blocks. The resistance to the clearing metal block increases, making it difficult to drive the clearing metal block to move. Moreover, if the coal powder accumulates too high, it is easy to pass over the clearing metal block, resulting in incomplete coal powder cleaning. Further improvements can be made.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-Figure 5 The coal sampling machine anti-blocking chute includes a chute body 1 with inclined sides. Side panels 2 are fixedly mounted on the tops of both sides of the chute body 1. A first embedding groove 3 is formed in the right side of the chute body 1, and a push claw 4 is embedded in the embedding groove 3. A fixing plate 5 is fixedly mounted on the top of the push claw 4. A second embedding groove 6 is formed in the left side of the chute body 1, and a second push claw 7 is embedded in the embedding groove 6. A fixing plate 8 is fixedly mounted on the top of the push claw 7. The first push claw 4 is inserted between two adjacent second push claws 7. The second push claw 7 is inserted between two adjacent first push claws 4. The first push claw 4 and the second push claw 7 are respectively flush with the two side walls of the chute body 1. The bottom ends of the first push claw 4 and the second push claw 7 are both attached to the bottom wall of the chute body 1. The fixing plates 5 and the second fixing plates 8 are respectively attached to opposite sides of the two side panels 2. This keeps the interior of the chute body 1 flat, facilitating the smooth sliding of coal blocks along the interior of the chute body 1.

[0026] A drive assembly 9 is provided on the opposite side of fixed plate 1 5 and fixed plate 2 8. This assembly is used to drive fixed plate 1 5 and fixed plate 2 8 toward each other. When fixed plate 1 5 and fixed plate 2 8 approach each other, push claws 1 4 and 2 7 push the coal dust inside chute body 1 toward the center, allowing the coal dust to be discharged through slots 1 3 and 2 6 and then slide downward along the bottom wall of chute body 1. Furthermore, when fixed plate 1 5 and fixed plate 2 8 move away from each other and reset, the coal dust that has fallen onto the back of push claws 1 4 and 2 7 is pushed toward slots 1 3 and 2 6 and out again.

[0027] See also Figure 4-Figure 5The drive assembly 9 includes a plurality of slide bars 91 fixedly mounted on opposite sides of the fixed plate 1 5 and the fixed plate 2 8. The slide bars 91 extend through and slideably connect to the side plate 2. The slide bars 91 support the fixed plate 1 5 and the fixed plate 2 8 and guide their movement paths. A connecting plate 92 is fixedly mounted between the other ends of the slide bars 91 on the same side. A vertical plate 93 is fixedly mounted at the center of the bottom of each connecting plate 92. A dual-axis motor 94 is provided at the lower middle portion of the chute body 1. The model of the dual-axis motor 94 is: YZP 132M1-6. A rotating shaft 95 is fixedly mounted on both output ends of the dual-axis motor 94. The surfaces of the two rotating shafts 95 are provided with threaded grooves 96 in opposite directions. A threaded hole is provided at the bottom end of the vertical plate 93. The rotating shaft 95 is threadedly connected to the threaded hole of the vertical plate 93 through the threaded groove 96. A dual-shaft motor 94 drives the two rotating shafts 95 to rotate, thereby moving the two vertical plates 93 closer together, and thus the fixed plates 1 5 and 2 8 closer together, causing the push claws 1 4 and 2 7 to gather the pulverized coal toward the center. When the push claws 1 4 and 2 7 intersect, they block the coal lumps in the pulverized coal above them, filtering the coal lumps. The push claws 1 4 and 2 7 scoop up some of the pulverized coal, which then slides down along the chute body 1 into the chute body 1 and then downward along the bottom wall of the chute body 1. As the push claws 1 4 and 2 7 move toward each other, they push the pulverized coal toward the embedded groove 3 and push claw 2 7 for discharge.

[0028] See also Figure 1-Figure 5 The bottom wall array of the chute body 1 is penetrated by a through hole 10. Therefore, during the movement of the push claw 1 4 and the push claw 2 7, the coal powder can be pushed to be discharged through the through hole 10. A cover plate 11 is fixedly installed on the top of the two side plates 2. The cover plate 11 blocks from the top to prevent the coal blocks scooped up by the push claw 1 4 and the push claw 2 7 from jumping out from the top of the side plate 2. A plurality of fixed columns 12 are fixedly installed at the bottom of the chute body 1, and a baffle 13 is fixedly installed at the bottom end of the fixed column 12. The baffle 13 is in an inverted V shape and is fixedly installed on the top of the dual-axis motor 94. The baffle 13 blocks the coal powder falling from the through hole 10 to prevent it from falling on the dual-axis motor 94. The width of the push claw 1 4 is equal to the distance between the two adjacent push claws 2 7, and the width of the push claw 2 7 is equal to the distance between the two adjacent push claws 1 4. Therefore, the area scraped by the push claw 1 4 and the push claw 2 7 on the bottom wall of the chute body 1 can cover the bottom wall of the chute body 1, thereby ensuring the coal powder cleaning effect.

[0029] Working Principle: The dual-axis motor 94 drives the rotating shaft 95 to rotate, thereby driving the two vertical plates 93 closer to each other. The connection between the connecting plate 92 and the slide bar 91 then drives the fixed plate 1 5 and the fixed plate 2 8 closer to each other, causing the pushing claws 1 4 and 2 7 to move toward the middle of the chute body 1, pushing the coal powder to gather toward the middle of the chute body 1, causing the coal powder to be discharged through the through hole 10, and part of the coal powder to be discharged through the embedded groove 1 3 and embedded groove 2 6, and the coal lumps in the coal powder are blocked at the top of the pushing claws 1 4 and 2 7.

[0030] Afterwards, the dual-axis motor 94 drives the rotating shaft 95 to rotate in the opposite direction, driving the push claw 1 4 and the push claw 2 7 to move in the opposite direction, moving the coal powder on the back of the push claw 1 4 and the push claw 2 7 to the embedded groove 1 3 and the embedded groove 2 6, and then discharged from the through hole 10, the embedded groove 1 3 and the embedded groove 2 6 again, thereby ensuring the cleaning effect of the coal powder.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
