[0008] According to the above-mentioned coal mining and conveying device, the upper surfaces of the two vertical plates are higher than the upper surface of the conveying assembly.

[0009] According to the above-mentioned coal mining and conveying device, the conveying assembly includes two conveying rollers that are rotatably arranged at intervals between two vertical plates. A conveyor belt is rotatably sleeved on the outer side of the two conveying rollers. A conveying motor for driving one of the conveying rollers to rotate is fixedly installed on the vertical plate located on the front side.

[0010] According to the above-mentioned coal mining and conveying device, a guide plate is fixedly connected to the right side of the two vertical plates, and the guide plate is set with the left side higher than the right side.

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

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Example: Refer to Figures 1 to 4 A coal mining and conveying device includes a conveying assembly. Specifically, the conveying assembly includes two conveying rollers 4 rotatably arranged between two vertical plates 3. A conveyor belt 5 is rotatably sleeved on the outer side of the two conveying rollers 4. A conveying motor 6 for driving one of the conveying rollers 4 to rotate is fixedly installed on the front vertical plate 3. When conveying coal, the coal is placed on the upper end of the conveyor belt 5, and the conveyor belt 5 rotates clockwise to transport the coal from left to right.

[0026] The two vertical plates 3 are fixedly connected to the right side of the guide plate 8, and the guide plate 8 is set with the left side higher than the right side. The guide plate 8 is set to facilitate the export of the coal conveyed by the conveying component.

[0027] It also includes an equipment box 1. Multiple casters 2 are rotatably mounted on the lower end of the equipment box 1 via a mounting plate. Two vertical plates 3 are vertically and symmetrically slidably connected to the top wall of the equipment box 1. The upper surfaces of the two vertical plates 3 are higher than the upper surfaces of the conveying components. The two vertical plates 3 can limit the coal mine on the conveying components to prevent the coal mine from falling off the sides of the conveying components during transportation, thus ensuring the conveying effect.

[0028] Both upright plates 3 are connected through the top wall of the equipment box 1. The conveying component is located at the top of the equipment box 1 and between the two upright plates 3. The equipment box 1 is equipped with a drive component 7 for driving the conveying component to rise and fall. Specifically, the drive component 7 includes a rotary motor 71 fixedly installed on the inner bottom wall of the equipment box 1. The output end of the rotary motor 71 is coaxially fixedly connected to a threaded rod 72. The lower ends of the two upright plates 3 are fixedly connected to a connecting plate 73. The threaded rod 72 is threaded through the connecting plate 73. When adjusting the height of the conveying component, the rotary motor 71 drives the threaded rod 72 to rotate, which drives the two upright plates 3 to rise and fall through the connecting plate 73, thereby changing the height of the conveying component and adjusting the height of the conveying component to a suitable position.

[0029] The top wall of the equipment box 1 is also equipped with a slag-cleaning component for cleaning the conveying assembly. Specifically, the slag-cleaning component includes two lifting rods 10 that are symmetrically and slidably connected through the top wall of the equipment box 1. A compression spring 12 is fixedly connected between the lifting rod 10 and the top wall of the equipment box 1. The compression spring 12 is always in a compressed state and is not in a state of extreme compression. The conveyor belt 5 of the conveying assembly presses down on the slag-cleaning plate 11, and the conveyor belt 5 abuts against the slag-cleaning plate 11. The compression spring 12 is compressed. On the one hand, the slag-cleaning plate 11 abuts against the conveyor belt 5, which makes it easy for the slag-cleaning plate 11 to scrape off and clean the residue adhering to the conveyor belt 5. On the other hand, the compression spring 12 is compressed, and the slag-cleaning plate 11 pushes the conveyor belt 5 upward, which can prevent the conveyor belt 5 from loosening and ensure the conveying effect of the conveyor belt 5.

[0030] The upper ends of the two lifting rods 10 are fixedly connected to a slag cleaning plate 11. The top wall of the equipment box 1 is provided with a slag discharge port 9, which is located at the left end of the slag cleaning plate 11. The equipment box 1 is provided with a residue collection box 13, which is located directly below the slag discharge port 9. The right wall of the equipment box 1 is provided with a conventional rotating door. When the residue collection box 13 collects a certain amount of residue, the residue collection box 13 is taken out from the equipment box 1 for centralized processing of the residue in the residue collection box 13.

[0031] The working principle of this utility model is as follows:

[0032] During use, the rotary motor 71 drives the threaded rod 72 to rotate, which in turn drives the two vertical plates 3 to rise and fall via the connecting plate 73. This causes the height of the conveying assembly to change, adjusting the height of the conveying assembly to a suitable position for conveying coal at different heights, thus improving flexibility. When conveying coal, the coal is placed on the upper end of the conveyor belt 5, which rotates clockwise to transport the coal from left to right. The two vertical plates 3 protect the coal during the conveying process, preventing it from falling and improving stability. During transport, the slag removal plate 11 located at the lower end of the conveyor belt 5 scrapes off the residue adhering to the outside of the conveyor belt 5, thus removing dirt and residue from the conveyor belt 5, making it easy to use again after transport, and highly practical.

[0033] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
