[0029] Example:

[0030] See also Figure 1-6 A scraper conveyor for coal mines comprises a feeding port 1, a shell 2 is fixedly connected to the lower end of the feeding port 1, a placing plate is fixedly connected to the front end of the shell 2, a crushing mechanism 3 is fixedly connected to the front and rear walls of the inner cavity of the shell 2, a guard plate 4 is fixedly connected to the inner cavity of the shell 2, a conveying mechanism 5 is fixedly connected to the left and right walls of the guard plate 4, and a fixing mechanism 6 is fixedly connected to the lower end of the guard plate 4.

[0031] In this solution, the mined coal blocks are placed into the outer shell 2 through the feed port 1. If the coal blocks are too large to fall into the conveying mechanism 5 from the outlet at the bottom of the outer shell 2, the crushing mechanism 3 can be used to crush the coal blocks first. After the large coal blocks are broken into small pieces, a coal bag can be put on the outside of the fixing mechanism 6, and coal blocks of uniform size will be transported into the bag, reducing the manual workload.

[0032] See also Figure 2-3 The crushing mechanism 3 includes a motor 31, the lower end of the motor 31 is fixedly connected to the upper end of the placement plate, the output end of the motor 31 is fixedly connected to a screw 32 through a coupling, the two sections of the thread on the outer surface of the screw 32 are in opposite directions, the outer surface of the screw 32 is threadedly connected to two crushing members 33, the two crushing members 33 are internally connected with a guide rod 34 for sliding connection, the rear ends of the screw 32 and the guide rod 34 are fixedly connected to the rear wall of the inner cavity of the shell 2, the crushing member 33 includes two displacement blocks 331, the lower ends of the two displacement blocks 331 are fixedly connected to a crushing plate 332, and the front end of the crushing plate 332 is fixedly connected to a plurality of crushing heads 333.

[0033] This solution starts the motor 31 and allows the screw 32 to rotate under the action of the motor 31. The rotation of the screw 32 causes the two crushing parts 33 to move toward each other on the outer surface of the screw 32, so that the two crushing plates 332 are clamped together, and the crushing head 333 is used to crush the larger coal block to make it smaller.

[0034] See also Figure 4The conveying mechanism 5 includes a second motor 51, the front end of the second motor 51 is fixedly connected to the rear end of the housing 2, the output end of the second motor 51 is slidably connected to a transmission belt 52 through a coupling, the inner surface of the transmission belt 52 is slidably connected to a transmission rod 53, the outer surface of the transmission rod 53 is slidably connected to the inner surface of the left wall of the guard plate 4, and the right end of the transmission rod 53 is fixedly connected to the right wall of the guard plate 4. The outer surface of the transmission rod 53 is fixedly connected to two gears 54, the outer surfaces of the two gears 54 are meshed and connected to two toothed belts 55, and the outer surfaces of the two toothed belts 55 are fixedly connected to a plurality of scrapers 56.

[0035] This solution starts the second motor 51, allowing the transmission belt 52 to drive the transmission rod 53 to rotate under the action of the second motor 51. The rotation of the transmission rod 53 will cause the two gears 54 located on its outer surface to rotate. Because the outer surfaces of the two gears 54 are meshed and connected with the two toothed belts 55, starting the second motor 51 can achieve the purpose of making the two toothed belts 55 and a number of scrapers 56 run together, and can transport coal blocks.

[0036] See also Figure 5-6 The fixing mechanism 6 includes a discharge pipe 61, the upper end of the discharge pipe 61 is fixedly connected to the lower end of the guard plate 4, two limit rings 62 are fixedly connected to the outer surface of the discharge pipe 61, and a fixing component 63 is movably connected to the outer surface of the discharge pipe 61. The fixing component 63 includes four arc plates 631, and the inner surfaces of the four arc plates 631 are fixedly connected with rubber pads 634. The ends of the four arc plates 631 that are close to each other are fixedly connected with arc telescopic rods 633, and the front end of the arc plate 631 at the front end is fixedly connected with a handle 632.

[0037] In this solution, the bag used to hold coal blocks is fixed at the discharge port through the fixing component 63, and manual bagging is not required. When in use, the handle 632 is pulled toward the front end to make the four arc-shaped plates 631 expand outward under the action of tension. At this time, the four arc-shaped telescopic rods 633 will also extend under the action of tension, and there will be a gap between the four rubber pads 634 and the rubber pads 634. The opening of the bag is placed between the outer surface of the discharge pipe 61 and the rubber pad 634, and the handle 632 is released. At this time, the rubber pad 634 and the four arc-shaped plates 631 will be tightened inwardly under the action of the four arc-shaped telescopic rods 633, and the bag will be fixed on the outer surface of the discharge pipe 61. The coal blocks can be directly transported into the bag through the conveying mechanism 5.

[0038] Working principle:

[0039] First, move the handle 632 to make the four arc plates 631 expand outward under the action of tension. At this time, the four arc telescopic rods 633 will also stretch under the action of tension. There will be a gap between the four rubber pads 634 and the rubber pads 634. Place the opening of the bag between the outer surface of the discharge pipe 61 and the rubber pad 634, and release the handle 632. At this time, the rubber pad 634 and the four arc plates 631 will be tightened inward under the action of the four arc telescopic rods 633, and the bag filled with coal will be fixed on the outer surface of the discharge pipe 61. Then, fill the mined coal blocks from the feed port 1 to make the coal blocks enter the inner cavity of the shell 2, start the motor 31, and let the screw 32 rotate under the action of the motor 31. The rotation of the screw 32 will cause the two crushing parts 3 The outer surfaces of the screw rod 32 move toward each other, so that the two crushing plates 332 are clamped together, and the crushing head 333 is used to crush the larger coal blocks. If there are no larger coal blocks, the two crushing plates 332 are used to push the coal blocks in the inner cavity of the shell 2 into the outlet to start conveying. The motor 2 51 is started, and the transmission belt 52 drives the transmission rod 53 to rotate under the action of the motor 2 51. The rotation of the moving rod 53 will cause the two gears 54 located on its outer surface to rotate. Because the outer surfaces of the two gears 54 are meshed and connected with the two toothed belts 55, starting the motor 2 51 can achieve the purpose of making the two toothed belts 55 run together with the plurality of scrapers 56 to convey the coal blocks, so that the coal blocks can directly enter the bag.

[0040] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto.
