It is an important step before coal utilization, which can significantly improve combustion efficiency, reduce pollution emissions, and lower transportation costs.

[0003] In the coal preparation process, coal needs to go through multiple processing stages, and the materials need to be transferred continuously and efficiently between each stage through transportation equipment. Among them, screw conveyors are one of the commonly used transportation equipment in coal preparation plants, and are particularly suitable for short-distance transportation of powdery, granular or small lump materials.

[0004] Through long-term observation, it has been found that existing conveyors, due to the influence of the working environment, inevitably have some moist materials coming into contact with the inner wall of the hopper. Over time, these materials tend to accumulate on the inner wall of the hopper, leading to material blockage. Therefore, a coal preparation conveying device is proposed to address the above problem.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figure 1-5As shown, a coal preparation conveying device includes a conveyor body 1; a conveyor motor 11 is installed at one end of the conveyor body 1; a hopper 12 is rotatably connected to the top of the conveyor body 1; a fixed frame 13 is fixedly connected to the top of the conveyor body 1; a rotating rod 14 is rotatably connected to the middle of the fixed frame 13; a limiting shaft 15 is fixedly connected to the end of the rotating rod 14; an internal toothed belt 16 is installed in the middle of the limiting shaft 15, and the other end of the internal toothed belt 16 is installed on the output shaft of the conveyor motor 11; a first bevel gear 17 is fixedly connected to the end of the rotating rod 14, and the first bevel gear 17 is located near the hopper 12; a second bevel gear 18 is fixedly connected to the outer wall of the hopper 12, and the second bevel gear 18 and the first bevel gear 17 are meshed with each other; during operation, the operator needs to install the conveyor body 1 in the designated working area and start the conveyor motor 11 to drive the spiral component inside the conveyor body 1 to rotate, at which time the material to be transferred in the hopper 12 can be short-circuited. In distance conveying, by arranging the hopper 12 to rotate, the output shaft of the conveyor motor 11 can drive the internal toothed belt 16 to move when it is working, causing the rotating rod 14 to rotate on the inner wall of the fixed frame 13. The second bevel gear 18, which meshes with the first bevel gear 17, can drive the second bevel gear 18 and the hopper 12 to rotate on the top of the conveyor body 1, gradually moving away from and then closer to the placed material, reducing the friction or adsorption force between the material and the inner wall of the hopper 12. This accelerates the transfer of accumulated material to the inner wall of the conveyor body 1 for conveying. This step, combined with the rotating hopper 12, can reduce the problem of some moist material accumulating on the inner wall of the hopper 12 after contact with it, reducing the phenomenon of material blockage in the hopper 12. Moreover, after the hopper 12 rotates, it can also accelerate the transfer of material in the hopper 12 to the inner wall of the conveyor body 1, thereby improving the material conveying work.

[0026] like Figure 1-5As shown, a fixing member 2 is fixedly connected to the outer wall of the hopper 12; a stirring rod 21 is slidably connected to the middle of the fixing member 2, and the stirring rod 21 is through the middle of the hopper 12; multiple sets of slots 22 are opened in the middle of the stirring rod 21; two sets of elastic members 23 are fixedly connected to the side wall of the fixing member 2; a push plate 24 is fixedly connected to the bottom of the end of the elastic member 23; a locking pin 25 is fixedly connected to the middle of the push plate 24, and the locking pin 25 is slidably set in the inner wall of the fixing member 2, and the shape of the locking pin 25 matches the locking slot 22; a pressure rod 26 is fixedly connected to the top of the push plate 24, and the fixing member 2 is set in the middle of the pressure rod 26; during operation, by setting the fixing member 2 on the side wall of the hopper 12, when the material that needs to be compacted in the hopper 12 needs to be dispersed, the worker can hold the middle of the fixing member 2 and squeeze the pressure rod 26 downward when in contact with the fixing member 2, while simultaneously moving the two sets of elastic members 23. After the clip 25 is extended until it disengages from the fixing part 2, the operator can push the stirring rod 21 to slide between the fixing part 2 and the inner wall of the hopper 12 until one end of the stirring rod 21 protrudes from the inner wall of the hopper 12. Then the support for the pressure rod 26 can be released, and under the action of the elastic force of the two sets of elastic parts 23, the clip 25 is once again engaged in the inner wall of the corresponding slot 22. This allows the protruding stirring rod 21 to disperse the material inside the hopper 12 during rotation. This step, combined with the set stirring rod 21, can further improve the stability of the material in the hopper 12 during feeding, and reduce the problem that the small gap between the materials in the hopper 12 makes it difficult to increase the material conveying speed by rotating the hopper 12 alone. In addition, under the action of multiple sets of slots 22, the protruding stirring rod 21 can be stored in the later stage, reducing the space occupied in the hopper 12.

[0027] like Figure 1-5As shown, a first magnetic block 3 is fixedly connected to the inner wall of the slot 22; two sets of spring rods 31 are installed on the inner wall of the latch 25; a second magnetic block 32 is fixedly connected to the top of the output end of the spring rod 31, and the second magnetic block 32 is slidably disposed on the inner wall of the latch 25, and the second magnetic block 32 and the first magnetic block 3 are mutually repulsive; a sliding plate 33 is fixedly connected to the bottom of the second magnetic block 32, and the sliding plate 33 is slidably disposed on the inner wall of the push plate 24 and the latch 25; during operation, because the first magnetic block 3 is provided on the inner wall of the fixing member 2, and it is necessary to latch the latch 25 onto the inner wall of the designated slot 22, the slot 22 gradually moves and, after approaching the position of the latch 25, the slot... The first magnetic block 3 and the second magnetic block 32 on the inner wall of 22 can generate a repulsive force, which squeezes the slide plate 33 to slide downward, so that the bright color on the surface of the slide plate 33 is displayed in the external area, and it is determined that the slot 22 and the pin 25 are aligned. When the first magnetic block 3 and the second magnetic block 32 move away from each other, the second magnetic block 32 can be reset under the action of the two sets of spring rods 31. This step, together with the slide plate 33 that can move up and down and the bright color area in the middle, can improve the stability of the operator in matching and fixing the slot 22 and the pin 25, and reduce the problem that the position of the two is slightly off, which is difficult for the operator to detect at the first time and requires repeated adjustments.

[0028] like Figure 1-5 As shown, a top ball 4 is fixedly connected to the bottom of the fixing member 2; a shield 41 is fixedly connected to the top of the conveyor body 1, and the top of the shield 41 is arc-shaped, and the rotating rod 14 is located inside the shield 41; an elastic sheet 42 is fixedly connected to the top of the shield 41, and the elastic sheet 42 and the top ball 4 are on the same plane; during operation, by setting the shield 41 on the top of the conveyor body 1, the unfolded shield 41 can block some of the falling material. When the hopper 12 rotates, the top ball 4 at the bottom of the fixing member 2 can contact the elastic sheet 42 and squeeze the elastic sheet 42 to deform it, and then move away to make the elastic sheet 42 return to its original position. Under the action of the arc-shaped shield 41, this step can reduce the amount of material approaching the rotating rod 14, which would cause jamming during subsequent rotation. Under the action of the contact between the top ball 4 and the elastic sheet 42, the shield 41 can generate vibration and accelerate the cleaning of impurities on its top.

[0029] like Figure 1-5 As shown, a limiting plate 5 is fixedly connected to the end of the stirring rod 21, and the limiting plate 5 is located inside the hopper 12; two sets of cutters 51 are fixedly connected to the side wall of the limiting plate 5; during operation, by setting the limiting plate 5 at the end of the stirring rod 21, the limiting plate 5 can reset the position of the stored stirring rod 21, and when the stirring rod 21 is in the protruding state, the cutters 51 can also cut the clumped material. This step, under the action of the cutters 51, can further improve the stability of the material feeding in the hopper 12, and the limiting plate 5 is used to limit the working position of the stirring rod 21.

[0030] like Figure 1-5 As shown, a gasket 6 is fixedly connected to the middle of the top ball 4. During operation, the gasket 6 is provided in the middle of the top ball 4 so that when the top ball 4 is close to the elastic sheet 42, the elastic sheet 42 can directly contact the gasket 6. This step, under the action of the soft material gasket 6, can reduce the wear on the elastic sheet 42 after contact and improve the convenience of subsequent maintenance of both.

[0031] Working principle: After the conveyor body 1 is installed in the designated working area, the conveyor motor 11 is started to drive the screw inside the conveyor body 1 to rotate. At this time, the material in the hopper 12 can be transported over a short distance. By setting the hopper 12 to rotate, when the conveyor motor 11 is working, its output shaft can drive the internal toothed belt 16 to move, and the rotating rod 14 rotates on the inner wall of the fixed frame 13. The second bevel gear 18, which meshes with the first bevel gear 17, can drive the second bevel gear 18 and the hopper 12 to rotate on the top of the conveyor body 1, gradually moving away from the placed material and then moving closer again, reducing the material's contact with the hopper. The friction or adsorption force of the inner wall of hopper 12 accelerates the transfer of accumulated material to the inner wall of the conveyor body 1 for conveying. A fixing member 2 is provided on the side wall of hopper 12. When the material that needs to be compacted in hopper 12 needs to be dispersed, the worker can hold the middle of the fixing member 2 and squeeze the pressure rod 26 downwards upon contact with the fixing member 2, simultaneously stretching the two sets of elastic members 23 until the locking pin 25 disengages from the fixing member 2. At this point, the worker can push the stirring rod 21 to slide between the fixing member 2 and the inner wall of hopper 12 until one end of the stirring rod 21 protrudes from the inner wall of hopper 12. Then, the support for the pressure rod 26 can be released, and under the elastic force of the two sets of elastic members 23, the material is further... The first step is to engage the locking pin 25 into the inner wall of the corresponding slot 22. During the rotation of the hopper 12, the protruding stirring rod 21 can disperse the material. Because the fixing member 2 has a first magnetic block 3 on its inner wall, as the locking pin 25 is engaged in the designated slot 22, the gradually moving slot 22 approaches the locking pin 25. At this point, the first magnetic block 3 and the second magnetic block 32 on the inner wall of the slot 22 generate a repulsive force, pressing the sliding plate 33 downwards. This causes the bright color on the surface of the sliding plate 33 to appear in the external area, indicating that the slot 22 and the locking pin 25 are aligned. Subsequently, when the first magnetic block 3 and the second magnetic block 32 move away from each other, the two sets of spring rods 31 can push the second magnetic block 32... To achieve position reset, a shield 41 is provided on the top of the conveyor body 1. The unfolded shield 41 can block some of the falling material. When the subsequent hopper 12 rotates, the top ball 4 at the bottom of the fixing member 2 can contact the elastic sheet 42 and squeeze the elastic sheet 42 to deform it. Then, it moves away, allowing the elastic sheet 42 to reset again. A limiting plate 5 is provided at the end of the stirring rod 21, so that the limiting plate 5 can reset the position of the stored stirring rod 21. When the stirring rod 21 is in the protruding state, the cutter 51 can also cut the clumped material. A gasket 6 is provided in the middle of the top ball 4, so that when the top ball 4 is close to the elastic sheet 42, the elastic sheet 42 can directly contact the gasket 6.
