Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0034] Please refer to Figure 1 、 Figure 3 The utility model provides technical scheme: reduce the coal mine material conveying pipeline of diffusion, including a plurality of through the flange 10 connected pipe body 1, and the top surface of pipe body 1 is set with through slot;

[0036] In the embodiment, as Figures 1-2 、 Figures 4-5As shown, the anti-expansion mechanism 3 is installed on the top surface of the pipe body 1 through two limiting mechanisms 5, and is used to reduce the dust diffusion of the coal mine materials during the conveying process. The anti-expansion mechanism 3 comprises an anti-expansion cover 31 and two connecting plates 32 fixed on the left and right side surfaces of the anti-expansion cover 31, respectively. The anti-expansion cover 31 is located directly above the same side pipe body 1, and corresponds to the position of the through slot on the top surface of the same side pipe body 1. The size of the anti-expansion cover 31 is greater than that of the through slot on the top surface of the pipe body 1, and the connecting plate 32 is tightly attached to the top surface of the same side pipe body 1. Two insertion slots are arranged on the top surface of the pipe body 1 near the left and right ends, respectively. Two insertion blocks 33 are fixed on the bottom surface of the connecting plate 32 and are slidably inserted into the same side insertion slot on the top surface of the same side pipe body 1. The anti-expansion mechanism 3 further comprises two lifting lugs 34 fixed on the top surface of the anti-expansion cover 31.

[0037] The anti-expansion cover 31 is located directly above the same side pipe body 1 and corresponds to the position of the through slot on the top surface of the same side pipe body 1. The size of the anti-expansion cover 31 is greater than that of the through slot on the top surface of the pipe body 1, so that the anti-expansion cover 31 can completely cover the through slot and effectively block the dust generated during the conveying process of the coal mine materials.

[0038] The connecting plate 32 is tightly attached to the top surface of the same side pipe body 1, which reduces the possibility of dust diffusing from the gap between the connecting plate 32 and the pipe body 1, thereby better reducing the diffusion of dust.

[0039] Two insertion slots are arranged on the top surface of the pipe body 1 near the left and right ends, respectively. Two insertion blocks 33 are fixed on the side surface of the connecting plate 32 near the same side pipe body 1 and are slidably inserted into the same side insertion slot on the top surface of the pipe body 1. This allows the anti-expansion mechanism 3 to be accurately and stably installed on the pipe body 1, and facilitates the disassembly and replacement of the anti-expansion mechanism 3. Two lifting lugs 34 are fixed on the top surface of the anti-expansion cover 31, which facilitates the lifting operation of the anti-expansion mechanism 3 by using lifting equipment and improves the efficiency of installation and disassembly.

[0040] In addition, as shown in the drawings, Figures 1-2 , Figures 6-7 A plurality of collection mechanisms 4 are arranged in the form of two in a group below the two sides of a plurality of anti-expansion covers 31, respectively, for collecting the scattered coal mine materials. The collection mechanism 4 comprises a collection box 41, the length of which is adapted to the length of the anti-expansion cover 31. A plurality of handles 43 are installed on the outer wall of the collection box 41. The collection mechanism 4 further comprises two U-shaped plates 42 fixed on the top surface of the collection box 41 near the left and right ends, and the horizontal plate end of the U-shaped plate 42 is fixed to the same side end of the same side connecting plate 32 through a plurality of screws.

[0041] The length of the collecting box 41 is matched with the length of the anti-expansion cover 31, so that the collecting box 41 can collect the coal mine materials scattered from both sides of the anti-expansion cover 31. The two U-shaped plates 42 are fixed on the top surface of the collecting box 41 near the left and right ends, and the horizontal plate end of the U-shaped plate 42 is fixed on the end of the same side connecting plate 32 through a plurality of screws, so that the collecting mechanism 4 can be firmly installed below the anti-expansion mechanism 3, ensuring effective collection of the scattered coal mine materials, avoiding waste of the coal mine materials and pollution to the surrounding environment.

[0042] Further, as shown in Figure 3 、 Figure 8 The limiting mechanism 5 includes a mounting plate 52 fixed on the top surface of the same side anti-expansion cover 31, a fixed plate 51 fixed on the top surface of the same side pipe body 1 and located between the same side flange 10 and the same side connecting plate 32, a spring 53 installed on one end of the mounting plate 52 near the surface of the fixed plate 51, a moving plate 54 installed on the other end of the spring 53, a guide block 56 fixed on the bottom surface of the moving plate 54 and slidingly connected to the top surface of the same side anti-expansion cover 31, a pull rod 57 fixed on the front side surface of the moving plate 54, and a limiting rod 55 fixed on the surface of the moving plate 54 away from the same side mounting plate 52 and slidingly inserted into the same side fixed plate 51. Two guide grooves are arranged on the top surface of the anti-expansion cover 31 and are symmetrically arranged and horizontally arranged. The guide block 56 is slidingly connected to the same side guide groove on the top surface of the same side anti-expansion cover 31. The longitudinal section shape of the guide groove on the top surface of the anti-expansion cover 31 is in the shape of an I-beam, and the shape of the guide block 56 is in the shape of an I-beam matched with the shape of the guide groove on the top surface of the anti-expansion cover 31.

[0043] In the limiting mechanism 5, the limiting rod 55 can be tightly inserted into the fixed plate 51 through the elastic action of the spring 53, so that the anti-expansion mechanism 3 is stably installed on the pipe body 1. The guide block 56 fixed on the bottom surface of the moving plate 54 is slidingly connected to the guide groove on the top surface of the same side anti-expansion cover 31, and the pull rod 57 fixed on the front side surface of the moving plate 54, so that the operator can pull the pull rod 57 to overcome the elastic force of the spring 53, so that the limiting rod 55 is extracted from the fixed plate 51, which is convenient for disassembling the anti-expansion mechanism 3;

[0044] Two guide grooves are arranged on the top surface of the anti-expansion cover 31 and are symmetrically arranged and horizontally arranged. The guide block 56 is slidingly connected to the same side guide groove on the top surface of the same side anti-expansion cover 31, so that the limiting mechanism 5 is more stable and smooth during movement, ensuring that the limiting rod 55 can be accurately inserted into and extracted from the fixed plate 51, and improving the operation reliability of the limiting mechanism 5;

[0045] The longitudinal section shape of the guide groove on the top surface of the anti-expansion cover 31 is in the shape of an I, and the shape of the guide block 56 is in the shape of an I matched with the shape of the guide groove on the top surface of the anti-expansion cover 31, so that the guide block 56 is not easy to disengage when sliding in the guide groove, further enhancing the stability and reliability of the limiting mechanism 5, and ensuring that the anti-expansion mechanism 3 can be firmly installed on the pipe body 1.

[0046] In the specific use process of the embodiment, first, several pipe bodies 1 are connected in sequence through the flanges 10, so that the assembly of the entire conveying pipeline is completed, and after assembly, the coal materials can be smoothly conveyed in the pipe body 1;

[0047] The anti-expansion mechanism 3 is installed on the top surface of the pipe body 1 by means of two limiting mechanisms 5, the anti-expansion cover 31 is located directly above the pipe body 1 and corresponds to the position of the through groove on the top surface of the pipe body 1, and the connecting plate 32 is tightly attached to the outer wall of the pipe body 1. The dust generated during the conveying of the coal materials will be blocked by the anti-expansion cover 31, changing the original dust raising direction and adjusting the discharge direction to the ground, thereby greatly reducing the diffusion of dust in the surrounding environment.

[0048] The collecting mechanism 4 is arranged in two groups below both sides of the anti-expansion cover 31, the length of the collecting box 41 is matched with the anti-expansion cover 31, and the collecting box 41 is fixed with the same side end of the same side connecting plate 32 through the U-shaped plate 42 and the screw. During the conveying of the coal materials, if part of the coal materials falls from the through groove on the top surface of the pipe body 1, it will directly fall into the collecting box 41, achieving effective collection of the scattered coal materials and avoiding resource waste and environmental pollution.

[0049] The spring 53 in the limiting mechanism 5 is in a natural state, and the limiting rod 55 is inserted into the fixed plate 51 under the elastic force of the spring 53. At this time, the insertion block 33 on the connecting plate 32 of the anti-expansion mechanism 3 is slidingly inserted into the insertion groove on the top surface of the pipe body 1, and the guide block 56 slides in the guide groove on the top surface of the anti-expansion cover 31, ensuring stable movement of the limiting mechanism 5 and firmly installing the anti-expansion mechanism 3 on the pipe body 1.

[0050] When the inside of the pipe body 1 needs to be repaired or cleaned, the pull rod 57 is pulled to drive the moving plate 54 to move against the elastic force of the spring 53, so that the limiting rod 55 is extracted from the fixed plate 51. Then, by means of the lifting lug 34 on the top surface of the anti-expansion cover 31, the anti-expansion mechanism 3 can be conveniently disassembled from the pipe body 1. At this time, the worker can check the inside of the pipe body 1 through the through groove on the top surface of the pipe body 1 and clean the blocked coal materials.
