DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] In order to make the technical means, creative features, achieved purposes and effects of the utility model easy to understand, the utility model will be further described below in conjunction with the specific embodiments.

[0025] Such as Figure 1As shown in the figure, a hoisting device for coal mine electromechanical transportation includes a first motor 1. The output end of the first motor 1 penetrates through a feed pipe 3. The output end of the first motor 1 is fixedly connected with a crushing assembly 2. One end of the feed pipe 3 away from the first motor 1 is lapped on a lifting pipe 6. One end of the lifting pipe 6 close to the feed pipe 3 is fixedly connected with a third motor 8. One end of the lifting pipe 6 away from the third motor 8 is lapped on a discharge pipe 5. One end of the discharge pipe 5 close to the lifting pipe 6 is fixedly connected with a second motor 7. Fixing assemblies 4 are fixedly connected to the outer surface of the lifting pipe 6 near the third motor 8 and the outer surface of the discharge pipe 5 near the second motor 7 respectively.

[0026] It should be noted that the first motor 1 is used to provide power to drive the crushing assembly 2 to rotate, and the contacting coal blocks are subjected to a certain degree of crushing treatment. The crushed coal blocks move downward due to gravity. When the coal blocks fall into the interior of the feed pipe 3, they are pushed into the interior of the lifting pipe 6 by the feed pipe 3, and the third motor 8 provides power to the lifting pipe 6 to continue to convey it upward into the interior of the discharge pipe 5. The second motor 7 provides power to the discharge pipe 5 to continue to push the coal blocks, so that the coal blocks are discharged from the discharge port of the discharge pipe 5. The angle can be adjusted through the fixing assemblies 4 installed on the discharge pipe 5 and the lifting pipe 6.

[0027] As Figure 2 shown in the figure, the crushing assembly 2 includes a second gear 25. The second gear 25 is fixedly connected to the output end of the first motor 1. A first gear 21 is meshed on the outer surface of the second gear 25. A crushing shaft 24 is fixedly connected to the middle of the first gear 21. Six groups of auxiliary hammers 23 distributed in a ring are fixedly connected to the outer surface of the crushing shaft 24. One end of each of the six groups of auxiliary hammers 23 away from the crushing shaft 24 is rotatably connected with an inertia hammer 22. One end of the feed pipe 3 near the first motor 1 is fixedly connected with a feed hopper 26, and the inertia hammers 22 and the auxiliary hammers 23 are located inside the feed hopper 26.

[0028] It should be noted that the first motor 1 drives the second gear 25, and the first gear 21 is driven to rotate through the second gear 25. The auxiliary hammers 23 are installed at staggered positions in each adjacent group on the crushing shaft 24, and the inertia hammers 22 are rotatably connected to the auxiliary hammers 23. When the crushing shaft 24 rotates, the inertia hammers 22 are thrown up due to inertia, thereby hitting the coal blocks to break them, and the auxiliary hammers 23 assist in crushing the coal blocks missed by the inertia hammers 22.

[0029] As Figure 3 shown in the figure, a feed blade 9 is fixedly connected to the middle of the side of the second gear 25 away from the first motor 1, the output end of the second motor 7, and the output end of the third motor 8. The three feed blades 9 are respectively located inside the feed pipe 3, the discharge pipe 5, and the lifting pipe 6.

[0030] It should be noted that a feed hopper 26 is arranged outside the crushing assembly 2 to ensure that the coal blocks can pass through the crushing assembly 2. The bottom of the feed hopper 26 is communicated with the feed pipe 3, and the crushed coal blocks can smoothly enter the interior of the feed pipe 3. The feed blades 9 arranged inside the feed pipe 3 are powered by the first motor 1 to convey the coal blocks to the next stage.

[0031] As Figure 4 shown, the fixing assembly 4 includes two ear frames 43, a slider 44 and two jigs 47. Fixing grooves 49 are formed on the opposite sides of the two jigs 47. Connecting rods 46 are fixedly connected to the opposite sides of the two jigs 47. Push rods 45 are fixedly connected to the sides of the two connecting rods 46 close to the ear frames 43. Two V-shaped grooves 48 are formed on the side of the slider 44 close to the push rods 45. The opposite ends of the two groups of push rods 45 are slidably connected to the inner walls of the V-shaped grooves 48. The sides of the two groups of push rods 45 close to the slider 44 are slidably arranged in the grooves of the ear frames 43 close to the connecting rods 46. A fixing frame 41 is fixedly connected to the opposite sides of the two ear frames 43. A cylinder 42 is fixedly connected to the side of the slider 44 away from the jig 47. The side of the slider 44 away from the push rod 45 is slidably connected to the side of the fixing frame 41 close to the cylinder 42.

[0032] It should be noted that the fixing frame 41 is installed on the surfaces of the discharge pipe 5 and the lifting pipe 6. The slider 44 is powered by the cylinder 42 to slide on the surface of the fixing frame 41. The ear frames 43 arranged on both sides of the fixing frame 41 can further limit the movement track of the slider 44 to prevent displacement. The push rod 45 is slidably connected in the groove on the surface of the ear frame 43. When the slider 44 moves, the push rod 45 will move along the V-shaped groove 48 on the surface of the slider 44. Under the cooperation of the groove on the surface of the ear frame 43, the push rod 45 moves to both sides, thereby pushing the connecting rod 46 to drive the jig 47 to move to both sides to complete unlocking.

[0033] As Figure 5 and Figure 6 shown, fixing rings 410 are fixedly connected to the ends of the feed pipe 3 close to the lifting pipe 6 and the ends of the lifting pipe 6 close to the discharge pipe 5. Annularly distributed stable grooves 411 are formed on the opposite sides of the two groups of fixing rings 410.

[0034] It should be noted that the fixing rings 410 arranged on the pipeline have opposite orientations when spliced, and the stable grooves 411 on the fixing rings 410 are away from the splicing place, so that the splicing surfaces during splicing match each other to prevent the leakage of coal mines.

[0035] As Figure 6 shown, two fixing blocks 412 are fixedly connected to the middle of the fixing groove 49, and the two fixing blocks 412 are located on both sides of the fixing groove 49 away from the fixing ring 410. The fixing blocks 412 are slidably connected inside the stable groove 411.

[0036] It should be noted that two fixing blocks 412 are arranged inside the fixing groove 49. The two fixing blocks 412 cooperate with the two stabilizing grooves 411 respectively to fix the two fixing rings 410. The stabilizing grooves 411 are annularly distributed and can still cooperate with the fixing blocks 412 after rotating a certain angle.

[0037] The working principle of the present utility model: Before operation, the device is adjusted according to the mine. Fixing frames 41 are installed on the surfaces of the discharge pipe 5 and the lifting pipe 6. The slider 44 is powered by the cylinder 42 so that it can slide on the surface of the fixing frame 41. The ear frames 43 arranged on both sides of the fixing frame 41 can further limit the movement track of the slider 44 to prevent displacement. The push rod 45 is slidably connected in the groove on the surface of the ear frame 43. When the slider 44 moves, the push rod 45 will move along the V-shaped groove 48 on the surface of the slider 44. With the cooperation of the groove on the surface of the ear frame 43, the push rod 45 moves to both sides, thereby driving the connecting rod 46 to drive the fixture 47 to move to both sides, and the angle of the pipeline can be adjusted. After determining the angle, the pipeline is locked and fixed by the cylinder 42. The first motor 1, the second motor 7 and the third motor 8 are started. The mined coal is put into the feed hopper 26. The first motor 1 provides power to drive the crushing assembly 2 and the feed pipe 3 to rotate synchronously through the meshing of the first gear 21 and the second gear 25. The auxiliary hammers 23 are staggeredly installed at adjacent positions on the crushing shaft 24. An inertial hammer 22 is rotatably connected to the auxiliary hammer 23. When the crushing shaft 24 rotates, the inertial hammer 22 is thrown up due to inertia, thereby hitting the coal blocks to break them. The auxiliary hammers 23 assist in crushing the coal blocks missed by the inertial hammer 22. The staggeredly arranged crushing shafts 24 are more conducive to the crushing of coal. The bottom of the feed hopper 26 is communicated with the feed pipe 3. The crushed coal blocks can smoothly enter the interior of the feed pipe 3. The feed blades 9 arranged inside the feed pipe 3 are powered by the first motor 1 to convey the coal blocks downward to the lifting pipe 6, and then the third motor 8 provides power to transport the coal to the discharge pipe 5, and finally the second motor 7 provides power to push the coal out of the discharge port of the discharge pipe 5.
