[0027] Example:

[0028] like Figure 1-4 As shown in this embodiment, a dust prevention device for a coal mine tunnel repair machine includes a repair machine body 1. A dust pump 2 is fixedly installed on the upper surface of the repair machine body 1. When the repair machine body 1 is in operation, the dust pump 2 is activated. The input end and output end of the dust pump 2 are respectively fixedly connected to a T-shaped connecting pipe 3 and a discharge pipe 4. A dust collection box 5 is provided on the repair machine body 1 located on one side of the dust pump 2. Both ends of the T-shaped connecting pipe 3 away from the dust pump 2 are fixedly connected to conveying hoses 6. The end of the conveying hose 6 away from the T-shaped connecting pipe 3 is fixedly connected to a dust collection hood 7. The dust pump 2 is located diagonally above the two dust collection hoods 7. When the dust pump 5 is activated, the dust pump 5 is activated. When dust pump 2 is running, it works in conjunction with two conveying hoses 6 via T-shaped connecting pipe 3 to create negative pressure inside the two dust collection hoods 7. The end of discharge pipe 4 away from dust pump 2 is connected to dust collection box 5. A cover 17 is detachably installed on the upper surface of dust collection box 5. Dust generated during the operation of the repair machine body 1 is sucked into the two conveying hoses 6 through the two dust collection hoods 7. The dust is then transported through T-shaped connecting pipe 3 and discharge pipe 4, and finally guided into dust collection box 5 for collection. Both dust collection hoods 7 are rotatably mounted on U-shaped support rods 8, and the two dust collection hoods 7 are symmetrically distributed about the central axis of U-shaped support rods 8. The outer surface of the repair machine body 1 is provided with a U-shaped support rod 8 and two symmetrically arranged mounting plates 9. Guide rods 10 are fixedly connected to the mounting plates 9, and push plates 11 are slidably connected to the two guide rods 10. A telescopic motor 12 is fixedly installed on the repair machine body 1. A connecting shaft 13 is fixedly connected to the output end of the telescopic motor 12. The end of the connecting shaft 13 away from the telescopic motor 12 is fixedly connected to the push plate 11. When the telescopic motor 12 runs, it drives the connecting shaft 13 to reciprocate. When the connecting shaft 13 moves towards the U-shaped support rod 8, it drives the push plate 11 to move towards the U-shaped support rod 8. A connecting block 14 is fixedly connected to the lower surface of the dust collection hood 7 near the rear end. A transmission plate 15 is hinged between each of the two connecting blocks 14 and the push plate 11. A limiting mechanism for limiting the two dust collection hoods 7 is provided on the U-shaped support rod 8. The two connecting blocks 14 and the two transmission plates 15 are symmetrically distributed about the central axis of the U-shaped support rod 8. The push plate 11 is guided by two guide rods 10. The push plate 11 drives the two transmission plates 15 to rotate. Since the two dust collection hoods 7 are rotated and sleeved on the U-shaped support rod 8, the two transmission plates 15 cooperate with the two connecting blocks 14 to make the two dust collection hoods 7 rotate.

[0029] like Figure 1 and Figure 4As shown, the limiting mechanism includes four limiting rings 16 fixedly sleeved on the U-shaped support rod 8. Two limiting rings 16 are respectively attached to the opposite side surfaces of one of the dust collection hoods 7, and the other two limiting rings 16 are respectively attached to the opposite side surfaces of the other dust collection hood 7. By cooperating with the four limiting rings 16, the two dust collection hoods 7 can be laterally limited to prevent the dust collection hoods 7 from shifting.

[0030] like Figure 1 , Figure 2 and Figure 4 As shown, the U-shaped support rod 8 is set vertically, and the U-shaped support rod 8 and the two mounting plates 9 are fixedly connected to the outer surface of the repair machine body 1.

[0031] Specifically, when using the dust control device of this coal mine tunnel repair machine: the dust pump 2 and the telescopic motor 12 are both electrically connected to the control power supply on the repair machine body 1. When the repair machine body 1 is operating, the dust pump 2 and the telescopic motor 12 are started. When the dust pump 2 is running, it cooperates with the two conveying hoses 6 through the T-shaped connecting pipe 3, creating a negative pressure inside the two dust collection hoods 7. The dust generated during the operation of the repair machine body 1 is sucked into the two conveying hoses 6 through the two dust collection hoods 7. The dust is then transported through the T-shaped connecting pipe 3 and the discharge pipe 4, and finally guided into the dust collection box 5 for collection. At the same time, when the telescopic motor 12 is running, it drives the connecting shaft 13 to move back and forth. When the connecting shaft 13 moves towards the U-shaped support rod 8, it drives the push plate 11 to move towards the U-shaped support rod 8. The push plate 11 is guided by the two guide rods 10. The 11 drives the two transmission plates 15 to rotate. Since the two dust collection hoods 7 are rotated and sleeved on the U-shaped support rod 8, the two transmission plates 15 cooperate with the two connecting blocks 14 to make the two dust collection hoods 7 rotate. Through the cooperation of the four limit rings 16, the two dust collection hoods 7 can be laterally limited. The openings of the two dust collection hoods 7 face diagonally downward. When the connecting shaft 13 moves away from the U-shaped support rod 8, it drives the push plate 11 to move and reset, so that the push plate 11 is in contact with the two mounting plates 9. Through the cooperation of the two transmission plates 15 and the two connecting blocks 14, the two dust collection hoods 7 are driven to rotate and reset to a horizontal state. Thus, when the telescopic motor 12 is running, the dust suction angle of the two dust collection hoods 7 can be adjusted, which can improve the dust collection range of the two dust collection hoods 7 to a certain extent, and the dust collection effect is better. It can play a better dust prevention role and greatly reduce the impact of dust on workers.

[0032] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
