[0027] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model are described clearly and completely. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] The embodiments of the present application provide a dust suppression device for crushing mine stones, which solves the problems that the broken stones flying everywhere will directly impact the spray head, and some fine stones will get stuck on the spray head, affecting the smooth spraying of water at the spray head, and realizes the protection during the dust suppression process of the spray head.

[0029] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0030] The embodiments of the present utility model disclose a dust suppression device for crushing mine stones.

[0031] As shown in the attached Figures 1-5 It includes a spray head 1 and an impact crusher 2 for supporting the spray head 1. The model of the impact crusher 2 is Liming PF-1214. A plurality of impact plates are arranged inside the impact crusher 2. When the mine stones enter the inside of the impact crusher 2, they will collide with the plurality of impact plates, so that the mine stones are broken. The broken stones are discharged through the outlet at the bottom end of the impact crusher 2. One end of the spray head 1 is connected to a water tank 12. A water pump 14 is arranged on the upper part of the water tank 12. A delivery pipe 13 is arranged between the spray head 1 and the water tank 12, and one end of the delivery pipe 13 is connected to the water pump 14. The mine stones enter the impact crusher 2 through the feed inlet of the impact crusher 2. At this time, the spray head 1 located at the feed inlet of the impact crusher 2 can spray water on the mine stones, so that the dust on the mine stones is absorbed by water and settles, thereby avoiding more dust from being raised at the impact crusher 2 and realizing dust suppression during the crushing process of the mine stones.

[0032] A protective mechanism 3 is provided outside the spray head 1. By means of the provided protective mechanism 3, on the one hand, it can prevent gravel and the like from directly contacting the spray head 1, thereby avoiding damage to the spray head 1. On the other hand, it can prevent blockage at the spray head 1 and ensure the smooth ejection of water at the spray head 1. The protective mechanism 3 includes a support frame 31. The support frame 31 is arranged at the feed inlet of the counter crusher 2. The hole in the middle of the support frame 31 coincides with the feed inlet of the counter crusher 2. A protective groove 32 is opened inside the support frame 31. The spray head 1 is arranged inside the protective groove 32. A main pipe 11 is fixedly connected to the top of the support frame 31. One end of the main pipe 11 is connected to the spray head 1, and the other end of the main pipe 11 is connected to the delivery pipe 13. A net plate 34 is rotatably arranged at the notch of the protective groove 32. A movable rod 33 is rotatably connected to the inner wall of the protective groove 32. One end of the net plate 34 is fixedly sleeved on the outer wall of the movable rod 33. The protective groove 32 and the net plate 34 provide all-round protection for the spray head 1, so that gravel does not contact the spray head 1. The U-shaped seat 35 is fixedly connected to the inner wall of the support frame 31. One end of the net plate 34 is movably connected inside the U-shaped seat 35. As shown in Attachment Figure 3 and Attachment Figure 5 shown, when the net plate 34 is impacted by water, it will rotate clockwise around the movable rod 33 as the axis. When gravel contacts the net plate 34 under the action of external force, at this time, the net plate 34 rotates counterclockwise around the movable rod 33 under the impact of the gravel. And one end of the net plate 34 is limited inside the U-shaped seat 35, so that the net plate 34 can shake up and down within a limited range, enabling the cleaning of small gravel and other impurities blocked in the mesh holes of the net plate 34.

[0033] An installation component 4 is arranged between the support frame 31 and the counter crusher 2. By means of the provided installation component 4, it is convenient to disassemble and assemble the spray head 1 and the counter crusher 2, so that when either party is damaged, the undamaged other party can be reused. The installation component 4 includes a threaded rod 41 fixedly arranged on one side of the counter crusher 2, a support frame 31 sleeved on the outer wall of the threaded rod 41, and a nut 43 threadedly sleeved on the outer wall of the threaded rod 41. An installation hole 42 adapted to the aperture of the threaded rod 41 is opened on the support frame 31. The support frame 31 is positioned and sleeved on the outer wall of the threaded rod 41 through the installation hole 42. After the support frame 31 is sleeved on the outer wall of the threaded rod 41, the nut 43 is threadedly sleeved on the threaded rod 41 until one side of the nut 43 abuts against one side of the support frame 31, so that the support frame 31 is fixed on one side of the counter crusher 2 at this time.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
