[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example 1

[0020] like Figure 1-4 As shown, the utility model provides a technical solution: an aggregate dust removal device for cement-stabilized crushed stone, comprising a crusher housing 1, wherein the upper and lower ends of the crusher housing 1 are respectively provided with a feed port and a discharge port, and a motor 2 is fixed to one side of the crusher housing 1, a crushing roller 3 is rotated in the crusher housing 1, and the stone is crushed by the cooperation of the motor 2 and the crushing roller 3, the output shaft of the motor 2 penetrates the crusher housing 1 and is fixedly connected to the crushing roller 3, and a water tank 4 is fixed to one side of the crusher housing 1, and the water tank 4 plays the role of storing water source, and a water pump 5 is fixed on the top of the water tank 4, and the water pump 5 is used to extract the water source in the water tank 4. The output end and the input end of the water pump 5 are fixed with a hose 6, and one end of the hose 6 is fixedly connected with the water tank 4. The hose 6 exists as a channel for water source transportation. Both sides of the crusher housing 1 are provided with through ports, and a protective shell 7 is provided at the channel opening of the crusher housing 1. The protective shell 7 protects the spray head 11 from the outside to prevent the spray head 11 from being transported to the crusher housing 1. In case that a stone from the material inlet is accidentally hit, a fixed sleeve 9 is fixed on the inner surface of the protective shell 7, one end of the hose 6 penetrates the protective shell 7 and is fixedly connected to the opening of the fixed sleeve 9, a water pipe 10 is arranged inside the fixed sleeve 9 and on the inner surface of the protective shell 7, and a spray head 11 is fixedly connected to one side of the water pipe 10, water is transported into the water pipe 10 and the spray head 11 through the hose 6, and the spray head 11 sprays the water over a large range, which is convenient for the subsequent dust reduction and dust removal operation. A blocking protection plate 13 is provided. By arranging the spray head 11 outside the crusher case 1, under the protection of the blocking protection plate 13, the situation in which the spray head 11 is damaged by the impact of small stones is avoided as much as possible, and a spray hole 14 is opened on the blocking protection plate 13. With the help of the spray hole 14, the spray head 11 can spray water on a large area of ​​the gravel inside the crusher case 1 through the blocking protection plate 13, thereby ensuring the function of reducing dust and removing dust inside the crusher case 1.

[0021] Example 2

[0022] like Figure 1-4As shown, the size and position of the spray hole 14 correspond to the water outlet holes on the spray head 11, which effectively reduces the interception amount of the spray water source by the blocking protection plate 13, and ensures the dust reduction and dust removal effect afterwards. The protective shell 7 is slidably connected to the crusher case 1, and the two ends of the water pipe 10 are rotatably connected to the protective shell 7 and the fixed sleeve 9 respectively. An electric telescopic rod 8 is fixed to one side of the protective shell 7, and one end of the electric telescopic rod 8 is fixed to the crusher case 1. The direction of the spray head 11 is changed by rotating the water pipe 10, so that the spray head 11 can spray water downward. With the help of the electric telescopic rod 8, the protective shell 7 can be moved to the inside of the crusher case 1, so that the spray head 11 is directly above the crushing roller 3, which is convenient for daily cleaning of the mud on the crushing roller 3, and avoids the mud from adhering to the crushing roller 3 for a long time, affecting the crushing roller 3 itself. Service life, one end of the water pipe 10 located inside the fixed sleeve 9 is fixedly connected with a sealing ring 12, and the fixed sleeve 9 serves as an intermediate bridge connecting the water pipe 10 and the hose 6, so that the hose 6 does not need to rotate when the water pipe 10 rotates, effectively avoiding the hose 6 from being squeezed after the rotation displacement, affecting the transmission of the water source, the sealing ring 12 effectively improves the airtightness of the connection between the fixed sleeve 9 and the water pipe 10, and reduces the occurrence of water leakage. A movable groove is opened at the corner of the protective shell 7, and a spring 16 is fixedly connected to the surface of the movable groove, and one end of the spring 16 is fixedly connected to one side of the blocking protection plate 13 with a connecting rod 15. With the help of the connecting rod 15, the blocking protection plate 13 can be stably moved outward when the spray head 11 is rotated and displaced, reducing the resistance of the spray head 11 during rotation displacement, and the spring 16 has the effect of automatically returning the blocking protection plate 13 to its original position.

[0023] Working principle:

[0024] like Figure 1-4 As shown, when the utility model is in use, the user first starts the motor 2 to drive the crushing roller 3 in the crusher case 1 to rotate, and then turns on the water pump 5 to extract the water source inside the water tank 4 through the hose 6, and then transmits it to the fixed sleeve 9 and the water pipe 10, and finally sprays it out in the spray head 11. The sprayed water source enters the crusher case 1 through the spray hole 14. At this time, the stone is transported to the feeding port of the crusher case 1 to enter the crusher case 1. The crushing roller 3 crushes the stone. At this time, the protective shell 7 and the blocking protection plate 13 jointly protect the spray head 11 to prevent it from being hit and damaged by the flying stones, and the dust generated during this period will be dusted and removed by the water sprayed from the spray hole 14.

[0025] After the crushing roller 3 has finished crushing the stones, due to the dust reduction operation, the humidity of the surrounding environment is high, which makes it easy for mud to adhere to its outer surface. In order to ensure its service life, it needs to be cleaned. At this time, the user first extends his hand into the interior of the protective shell 7 from the gap end below the protective shell 7, and then holds the water pipe 10 to control it and the spray head 11 to rotate, so that the water outlet of the spray head 11 faces downward, and the protective plate 13 and the connecting rod 15 are blocked from moving outward during the rotation of the spray head 11. The spring 16 is stretched. After the rotation of the spray head 11 is completed, the spring 16 rebounds to allow the protective plate 13 and the connecting rod 15 to move back to their original positions, and then the electric telescopic rod 8 is controlled to shrink, driving the protective shell 7 to slide into the crusher case 1, and finally the spray head 11 moves to the top of the crushing roller 3. Then, the crushing roller 3 is rotated so that the spray head 11 sprays water on it at a close distance, which is convenient for cleaning the mud on the crushing roller 3.

[0026] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
