[0030] Refer to the attached Figures 1-4 , a crusher for the production of dry-mixed plastering mortar, including a discharge track 1. The middle part of the top surface of the discharge track 1 is connected to a crushing box 2. The discharge track 1 is matched and connected to a discharge device 3. The top of the crushing box 2 is symmetrically provided with crushing rollers 4. One side of the crushing roller 4 is provided with a rotating motor 5. The side of the rotating motor 5 is connected to a cooling water pump 6 through a first water pipe. The top of the rotating motor 5 is provided with a water spraying and dust reduction part 7. The water spraying and dust reduction part 7 is connected to the rotating motor 5 through a second conveying pipe. When the device works, the stones and rocks to be crushed are put into the entrance at the top of the crushing box 2. The two rotating motors 5 on both sides start to work, and the two crushing rollers 4 rotate towards each other, so that the stones and rocks are continuously squeezed and crushed into fine particles. According to the specification requirements of the dry-mixed plastering mortar, they can be further crushed into sand subsequently. When the two rotating motors 5 on both sides are working, the cooling water pump 6 is connected to the water supply pipe, and the cooling water will be conveyed into the rotating motor 5 for cooling. Then, it enters the water spraying and dust reduction part 7 at the top through the second conveying pipe and is sprayed onto the top of the crushing box 2 to reduce the dust emission during crushing. Finally, the crushed stones and rocks are conveyed outwards through the discharge device 3 at the bottom. This device can not only continuously cool the rotating motor 5 through the cooling water, but also send the water passing through the rotating motor 5 into the water spraying and dust reduction part 7 for water spraying and dust reduction, reducing the impact of dust on the production workshop.
[0031] The discharge track 1 includes a sliding bottom plate 11. The top of the sliding bottom plate 11 is symmetrically provided with sliding grooves 12. A rotating lead screw 13 is arranged in the sliding groove 12. One end of the rotating lead screw 13 is connected to a driving motor 14. The discharge device 3 is matched and connected in the sliding groove 12. When the discharge device 3 is filled with the crushed material, the driving motor 14 drives the rotating lead screw 13 to rotate, and then drives the discharge device 3 at the top to move in the sliding groove 12.
[0032] The discharge device 3 includes symmetrically arranged storage boxes 31. The middle parts of the storage boxes 31 are connected through a partition conical block 32. The discharge box 33 is slidably connected in the storage box 31. The inner sides of the discharge box 33 are symmetrically provided with transfer handles 34. The two storage boxes 31 can alternately discharge the crushed sand and gravel. When receiving materials, the driving motor 14 at the top drives one of the discharge boxes 33 to enter the bottom of the crushing box 2 for receiving materials. When the materials in this side of the discharge box 33 are almost full, the driving motor 14 drives it to slide outwards, and the other discharge box 33 starts to receive materials. The partition conical block 32 can ensure that the sand and gravel fall into the discharge box 33 as much as possible. The staff connects the transfer handle 34 through a forklift or a crane, takes out the inner discharge box 33 from the storage box 31, and puts in a new discharge box 33 to wait for subsequent receiving materials.
[0033] The water spraying and dust reduction part 7 includes a first support plate 71 which is arranged on both sides of the crushing box 2. Both ends of the first support plate 71 are connected to sliding seats 72. The inner sides of the sliding seats 72 are slidably connected to lifting sliders 73. The inside of the lifting sliders 73 is connected to a concave baffle 74. The bottom of the concave baffle 74 is connected to the first support plate 71 through a spring 75. The concave baffle 74 is provided with dust reduction nozzles 76 at intervals. The rear end of the concave baffle 74 is provided with a connection port connected to the second conveying pipe. The water spraying and dust reduction part 7 can continuously spray water to the feeding port of the crushing box 2 through the dust reduction nozzles 76, reducing the occurrence of dust overflow. To prevent the dust reduction nozzles 76 from being damaged by the stones in the feed, the bottom of the concave baffle 74 is connected to the spring 75. After a larger stone hits the concave baffle 74, it will move downward until it is lower than the edge of the crushing box 2, thereby reducing the damage rate of the dust reduction nozzles 76.
[0034] One side of the concave baffle 74 facing the crushing box 2 is connected to a protection plate 741. The protection plate 741 is provided with water spraying holes 742. The protection plate 741 can further protect the dust reduction nozzles 76. The water spraying holes 742 are biased towards the water spraying operation of the dust reduction nozzles 76.
[0035] In the middle of the bottom surface of the crushing roller 4, an adsorption mechanism 41 is provided. The adsorption mechanism 41 includes a triangular support plate 42. One end of the triangular support plate 42 is connected to the inside of the crushing box 2. A discharge notch 43 is formed in the crushing box 2 at the other end of the triangular support plate 42. The top of the triangular support plate 42 is slidably connected to a herringbone magnetic adsorption plate 44. A sealing door 45 is arranged outside the discharge notch 43. There may be a small amount of magnetic metal particles doped in the raw sand and gravel. This device can adsorb the magnetic metal through the adsorption mechanism 41. During operation, the cleaned herringbone magnetic adsorption plate 44 is inserted into the top of the triangular support plate 42, and the sealing door 45 is closed. When the crushing box 2 is working, the crushed sand and gravel will roll down through the herringbone magnetic adsorption plate 44, and the magnetic metal substances will be adsorbed during the rolling process. After adsorption for a period of time, the sealing door 45 is opened, the herringbone magnetic adsorption plate 44 is taken out for cleaning, and at the same time, a new herringbone magnetic adsorption plate 44 is inserted into the triangular support plate 42.
[0036] The above embodiments only represent a certain implementation manner of the present invention, and its description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention; it should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention; therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
