The outer wall of the telescopic rod 28 is sleeved with a spring 29. The spring 29 is usually made of a metal material with certain elasticity. The spring 29 is tightly sleeved on the outer wall of the telescopic rod 28, with its top end fixedly connected to the top inner wall of the base 1 by welding or using connecting pieces, and its bottom end fixedly connected to the top end of the lifting plate 27. The spring 29 plays a role in buffering and auxiliary support during lifting. The bottom end of the lifting plate 27 is fixedly connected with two wheels 30. The wheels 30 are usually made of wear-resistant rubber or other suitable materials.The wheels 30 are fixedly connected to the bottom end of the lifting plate 27 by means of bolts or welding, etc., so that the whole device can be rolled more conveniently when it needs to be moved.
[0037] Working principle: The to-be-crushed material is first placed on the conveyor belt 2 and is steadily sent into the solid shell 5 as the conveyor belt 2 runs slowly. Inside the shell 5, the motor 10 begins to exert its powerful driving force. The motor 10 drives the roller 11 to rotate at a stable speed. The roller 11 is usually made of hard material and has strong crushing force, which can gradually crush the material entering the shell 5. When the material is fully crushed, it will be discharged through the specially designed discharge port 7. A filter plate 12 is arranged in the shell 5. The finer material will fall through the pores of the filter plate 12 under the action of gravity and material flow, and finally accurately fall into the material collecting box 8. The material collecting box 8 can collect these finer materials for subsequent further processing or other purposes. Start the water pump 13, which begins to pump water from the water tank 3. The water tank 3 usually stores a certain amount of clean water to meet the dust removal needs. The pumped water is transmitted through the solid water pipe 14, and due to the pressure action of the water pump 13, the water flows quickly in the water pipe 14 and is finally sprayed out of the high-pressure nozzle 15. The high-pressure nozzle 15 can spray water in the form of fine mist, which can effectively adsorb dust in the air and make it settle down. In order to improve the coverage range and dust removal effect of the water mist, start the motor 17. The motor 17 drives the rotating rod 18 to rotate at a constant speed. One end of the rotating rod 18 is cleverly sliding on the inner wall of the sliding groove 20. When the rotating rod 18 rotates, it will drive the rotating block 19 to swing regularly due to the interaction with the sliding groove 20. The rotating block 19 is connected to the high-pressure nozzle 15 through a special connecting device, so the swing of the rotating block 19 will finally drive the high-pressure nozzle 15 to swing. In this way, the high-pressure nozzle 15 can swing within a certain angle range.
[0038] The pushing end of the electric push rod 22 slowly extends and then pushes the pushing block 23 fixedly connected thereto with force. The pushing block 23 is pushed by the electric push rod 22, and the round rod 25 slides on the inner wall of the slot 24. Due to the design of the shape and position of the slot 24, the movement track of the round rod 25 is accurately limited. With the continuous pushing of the pushing block 23, the sliding of the round rod 25 in the slot 24 promotes the lifting of the vertical block 26 fixedly connected thereto. The vertical block 26 is driven by the round rod 25 and slides upward along the inner wall of the base 1. With the lifting of the vertical block 26, the lifting plate 27 fixedly connected thereto is also driven to move upward. The lifting plate 27 is driven by the vertical block 26 and starts to lift the wheel 30 fixedly connected to the bottom end thereof. The telescopic rod 28 installed at the four corners of the top end starts to perform the telescopic action. When the lifting plate 27 is lifted, the telescopic part of the telescopic rod 28 is gradually contracted to provide the guiding and stabilizing effect for the lifting of the lifting plate 27. At the same time, the spring 29 sleeved on the outer wall of the telescopic rod 28 is also compressed.
[0039] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing detailed description of the present application, for the skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the scope of the present application.
