[0002] In the coal processing process, raw coal often needs to be crushed to meet the requirements of subsequent combustion or transportation. Traditional crushing equipment mostly relies on gravity for natural discharge. When the coal has a high moisture content or fine particles, it is very easy to form bridges or accumulations at the discharge port, which can lead to blockages and affect continuous operation.

[0003] Some crushers using a single roller press structure allow material to fall directly after crushing, lacking effective discharge guidance. The discharge channel is easily blocked, requiring frequent shutdowns for cleaning, which not only reduces production efficiency but also increases maintenance costs and safety risks.

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0020] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0021] Example 1 Reference Figure 1-4 In the first embodiment of this utility model, an anti-blocking component 1 is provided, including a feed inlet 101, a processing box 102, and a discharge outlet 103. The feed inlet 101 is located at the upper end of the processing box 102, and the discharge outlet 103 is located at the lower end of the processing box 102. A crushing mechanism 2 is provided on the inner wall of the upper end of the processing box 102, and an anti-blocking mechanism 3 is provided at the lower end of the processing box 102. The crushing mechanism 2 is used to crush coal, and the anti-blocking mechanism 3 prevents blockage.

[0022] Specifically, the anti-blocking component 1 forms a closed material channel by connecting the inlet 101, the processing box 102, and the discharge port 103, effectively preventing dust from overflowing and improving the working environment. The processing box 102 is equipped with a crushing mechanism 2 at the upper end and an anti-blocking mechanism 3 at the lower end, realizing the orderly connection between crushing and discharge. The crushing mechanism 2 performs preliminary particle size control on the coal, reducing the risk of large pieces of material entering the discharge area. In conjunction with the reciprocating motion of the lower anti-blocking mechanism 3, the discharge port 103 area is continuously disturbed to prevent damp or fine coal particles from bridging and accumulating and causing blockage.

[0023] Furthermore, when the coal enters the processing area, it is first poured into the processing box 102 through the feed inlet 101. Under the action of gravity, the material falls to the starting position of the crushing mechanism 2 and is crushed by the crushing mechanism 2. The anti-blocking mechanism 3 prevents blockage.

[0024] Example 2 The second embodiment of this utility model provides a crushing mechanism 2 including a protective cover 201, a servo motor 202, a drive gear 203, a crushing roller 204, a mating roller 205, a driven gear 206, and a transmission shaft 207. The surface of the protective cover 201 is fixedly connected to the surface of the servo motor 202. The output end of the servo motor 202 is fixedly connected to the inner wall of the drive gear 203. The surface of the drive gear 203 is fixedly connected to the surface of the crushing roller 204. The surface of the mating roller 205 is fixedly connected to the surface of the driven gear 206. The surface of the driven gear 206 is fixedly connected to the surface of the transmission shaft 207. The surface of the protective cover 201 is fixedly connected to the surface of the processing box 102. The drive gear 203 and the driven gear 206 are both disposed inside the protective cover 201. Both ends of the crushing roller 204 and the mating roller 205 are rotatably connected to the inner wall of the processing box 102. The tooth surface of the drive gear 203 meshes with the tooth surface of the driven gear 206. The surface of the transmission shaft 207 is rotatably connected to the inner wall of the protective cover 201.

[0025] Specifically, the crushing mechanism 2 drives the drive gear 203 via the servo motor 202, which in turn drives the crushing roller 204 and the mating roller 205 to rotate relative to each other in a meshing state, forming a stable extrusion and shearing force to effectively crush large pieces of coal. The drive gear 203 and the driven gear 206 are placed inside the protective cover 201 to prevent dust from entering and causing wear or jamming of the tooth surface, thereby improving transmission stability and service life. Both ends of the crushing roller 204 and the mating roller 205 are rotated and supported by the inner wall of the processing box 102 to ensure concentricity of operation and uniform force distribution, thereby reducing vibration.

[0026] Furthermore, under the action of gravity, the material falls to the starting position of the crushing mechanism 2 and contacts the surfaces of the crushing roller 204 and the mating roller 205. At this time, the servo motor 202 starts, and the drive gear 203 at its output end rotates. Through meshing transmission, it drives the driven gear 206 on the mating roller 205 to rotate synchronously. Because the drive gear 203 and the driven gear 206 mesh, the crushing roller 204 and the mating roller 205 rotate relative to each other, forming a squeezing and shearing action to crush large pieces of coal. This process relies on the gap between the two rollers to control the output particle size, ensuring that the coal is uniformly crushed to the required size.

[0027] Example 3 The third embodiment of this utility model provides an anti-blocking mechanism 3, including a transmission component 301, a tensioning wheel 302, a reciprocating screw 303, a bearing seat 304, a transmission block 305, and an anti-blocking plate 306. The surface of the transmission component 301 is connected to the surface of the tensioning wheel 302. The surface of the reciprocating screw 303 is rotatably connected to the inner wall of the bearing seat 304. The surface of the transmission block 305 is fixedly connected to the surface of the anti-blocking plate 306. The surface of the transmission shaft 207 is connected to the inner side of the two transmission components 301. The surface of the bearing seat 304 is fixedly connected to the surface of the processing box 102. The two transmission components 301 are connected to the surfaces of the two reciprocating screws 303. The surface of the reciprocating screw 303 is threadedly connected to the inner wall of the transmission block 305. The surface of the transmission block 305 is slidably connected to the lower inner wall of the processing box 102 through a sliding groove. The surface of the anti-blocking plate 306 is movably connected to the inner wall of the processing box 102.

[0028] Specifically, the anti-blocking mechanism 3 ensures smooth power transmission and avoids slippage through the transmission cooperation between the transmission component 301 and the tensioning wheel 302; the reciprocating screw 303 rotates stably under the support of the bearing seat 304, and achieves axial movement in cooperation with the threaded transmission block 305; the anti-blocking plate 306 is fixed to the transmission block 305 and moves smoothly back and forth under the guidance of the slide groove, effectively disturbing the material in the discharge port 103 area, destroying the bridging structure, improving the continuity and reliability of discharge, solving the problem that wet or fine-particle coal is easy to block the discharge port 103, and ensuring the continuous operation of the crushing operation.

[0029] Furthermore, the crushed coal moves down the inner wall of the processing box 102 to the discharge port 103 under the action of gravity. To ensure smooth discharge and prevent bridging and blockage, the transmission shaft 207 on the driven gear 206 rotates synchronously with the crushing roller 204. The transmission shaft 207 connects two transmission components 301, which transmit power to the reciprocating screws 303 at both ends of the processing box 102. The transmission components 301 convert the rotational motion into the alternating forward and reverse motion of the screw, causing the transmission block 305 on the screw to move axially and periodically. The transmission block 305 is connected to the anti-blocking plate 306, which drives it to move horizontally and reciprocally in the discharge channel, disturbing the coal, destroying the material arch bridge structure, clearing the accumulation area of ​​the discharge port 103, and reducing the risk of blockage.

[0030] Working principle: When coal enters the processing chamber, it is first poured into the processing box 102 through the feed inlet 101. Under the action of gravity, the material falls to the starting position of the crushing mechanism 2, directly contacting the surfaces of the crushing roller 204 and the mating roller 205. At this time, the servo motor 202 starts, and the drive gear 203 connected to its output end begins to rotate. Through meshing transmission, it drives the driven gear 206 installed on the mating roller 205 to rotate synchronously. Due to the meshing of the drive gear 203 and the driven gear 206, the crushing roller 204 and the mating roller 205 rotate in opposite directions, forming an effective squeezing and shearing action, gradually crushing large pieces of coal. This crushing process relies on the gap between the two rollers to control the output particle size, ensuring that the coal is uniformly crushed to the required size. The crushed coal moves downward along the inner wall of the processing box 102 under its own gravity, and finally reaches the discharge port 10. 3. To ensure smooth material discharge and prevent bridging and blockage caused by moisture or fine particle accumulation, a transmission shaft 207 is fixed on the rotating shaft of the driven gear 206. It rotates synchronously with the crushing roller 204. The transmission shaft 207 connects two transmission components 301, transmitting power to two reciprocating screws 303 located at both ends of the processing box 102. The transmission components 301 convert the continuous rotational motion into the alternating forward and reverse motion of the reciprocating screws 303, causing the transmission blocks 305 mounted on the screw surface to move periodically along the axial direction. The transmission blocks 305 are connected to the anti-blocking plate 306, so their axial movement directly drives the anti-blocking plate 306 to move horizontally back and forth in the discharge channel at the bottom of the processing box 102. This movement effectively disturbs the coal material that is about to be discharged, destroys the material arch structure that may be formed, and continuously cleans the accumulation area around the discharge port 103, thereby reducing the risk of blockage.

[0031] In summary, through the coordinated operation of servo motors, gear transmission, reciprocating screws, and anti-blocking plates, efficient crushing and continuous and stable discharge of coal are achieved, effectively preventing the problem of discharge port blockage caused by material accumulation.
