When the crushing roller 1 8 and the crushing roller 2 11 crush the construction waste, a large amount of floating dust is likely to appear. Therefore, when the rack 14 moves downward, it will drive the piston plate 15 to slide down on the inner wall of the water pumping box 29, thereby compressing the pumping water. The water flow inside the box body 29, the water pressure becomes larger at this time, and then the water flow inside the water pumping box body 29 is introduced into the drain pipe 32 through the check valve two 33, and sprayed on the crushing roller 1 8 and crushing roller 2 11 to crush construction waste At the same time, the surface of the crushing roller 1 8 and the crushing roller 2 11 can be cleaned to prevent the phenomenon of clogging.

Embodiment 4:

As shown in Figures 7-8, on the basis of the third embodiment, further expansion: the front of the feed housing 6 is fixedly connected with a positioning plate 22, and the end of the positioning plate 22 away from the feed housing 6 is provided with a limiting groove 23. The inner wall of the limit slot 23 is rotatably connected with the second shaft 24, the rear end of the limit slot 23 is fixedly connected with the fourth gear 25, and the front end of the second shaft 24 and the front end of the third shaft 27 are connected with a belt 26.

Preferably, the fourth gear 25 is not meshed with the rack 14 , and the fourth gear 25 can be meshed with the third gear 16 when the crushing box 4 is under less load.

When the internal load of the crushing box 4 is small, due to the elastic potential energy of the spring telescopic rod 2, the supporting plate 3 and the crushing box 4 will be kept at a certain height. Therefore, the heights of the first rotating shaft 17 and the third gear 16 change with the height of the crushing box 4, and since the height of the feeding housing 6 remains unchanged, the heights of the positioning plate 22 and the second rotating shaft 24 also remain unchanged. At this time, the outer wall of the third gear 16 can be meshed and connected with the outer wall of the fourth gear 25.

The working principle of this scheme: When the environmental protection treatment device for construction waste for civil engineering is in use, the construction waste to be crushed is put into the feeding housing 6, the driving motor 7 is started, and the crushing roller 1 8 is driven by the driving motor 7 to rotate clockwise. , Since the gear one 9 is coaxially fixed with the grinding roller one 8, the grinding roller one 8 will drive the gear one 9 to rotate clockwise, and then drive the gear two 10 meshingly connected with the gear one 9 to rotate counterclockwise, because the grinding roller two 11 It is coaxially fixed with the second gear 10, so the second gear 10 will drive the second grinding roller 11 to rotate counterclockwise. At this time, the first grinding roller 8 rotates clockwise, and the second grinding roller 11 rotates counterclockwise, which will be thrown into the crushing box 4. Compared with the traditional extrusion method or the crushing arm for direct crushing and crushing, the crushing effect is better;

Through the rotation of the first gear 9 and the second gear 10, the movable plate 12 in the eccentric position of the first gear 9 and the second gear 10 will be driven to move up and down periodically, thereby pushing the connecting plate 13 and the rack 14 to move up and down periodically, thereby driving the gear rack 12 to move up and down periodically. 14. The gear three 16 meshed and connected alternately rotates forward and reverse, thereby driving the rotating shaft one 17 and the convex plate 18 to rotate forward and reverse alternately, thereby driving the slider on the outer wall of the rotating shaft one 17 to slide on the inner wall of the chute 20, and then Drive the steering plate 19 to deflect left and right with the top as the axis, and then drive the dredging plate 21 at the bottom of the second gear 10 to deflect left and right, which can continuously move the crushed construction waste, so that the upper surface of the construction waste is in a flat state to prevent falling The accumulation of construction waste caused by the internal blockage of the crushing box 4, making it inconvenient to unload the material;

When the internal load of the crushing box 4 is small, due to the elastic potential energy of the spring telescopic rod 2, the supporting plate 3 and the crushing box 4 will be kept at a certain height. Therefore, the heights of the first rotating shaft 17 and the third gear 16 change with the height of the crushing box 4, and since the height of the feeding housing 6 remains unchanged, the heights of the positioning plate 22 and the second rotating shaft 24 also remain unchanged. At this time, the outer wall of the third gear 16 can be meshed and connected with the outer wall of the fourth gear 25. Therefore, when the third gear 16 rotates, it will drive the fourth gear 25 to rotate synchronously, and then drive the second shaft 24 to rotate. Through the transmission action of the belt 26, It will drive the rotating shaft three 27 to rotate synchronously, and then drive the feeding plate 28 to rotate. Through the rotation of the feeding plate 28, the construction waste inside the feeding shell 6 can be transferred to the opening position of the crushing box 4, so as to realize the function of automatic blanking and automatic crushing. ;

When the inside of the crushing box 4 is blocked, the construction waste inside the crushing box 4 gradually accumulates, so that the weight inside the crushing box 4 gradually increases. When the gravitational potential energy of the crushing box 4 is greater than the elasticity of the spring telescopic rod 2 When the potential energy is present, the spring telescopic rod 2 will be compressed, and then the support plate 3 and the crushing box 4 will be moved downward synchronously. At this time, the third gear 16 is gradually disengaged from the fourth gear 25. At this time, the fourth gear 25 and the second rotating shaft 24 are not rotating, and at the same time The belt 26 and the third rotating shaft 27 are no longer rotating, so the feeding plate 28 no longer introduces the waste material inside the feeding housing 6 into the crushing box 4, but the crushing roller 1 8 and the crushing roller 2 11 still function normally until After the construction waste inside the crushing box 4 is gradually crushed and discharged, the weight of the crushing box 4 is reduced. At this time, the third gear 16 will mesh with the fourth gear 25 again, so that the feeding plate 28 rotates and feeds the waste inside the housing 6. Imported into the crushing box 4 to realize the function of intelligent feeding;

When the crushing roller 1 8 and the crushing roller 2 11 crush the construction waste, a large amount of floating dust is likely to appear. Therefore, when the rack 14 moves downward, it will drive the piston plate 15 to slide down on the inner wall of the water pumping box 29, thereby compressing the pumping water. The water flow inside the box body 29, the water pressure becomes larger at this time, and then the water flow inside the water pumping box body 29 is introduced into the drain pipe 32 through the check valve two 33, and sprayed on the crushing roller 1 8 and crushing roller 2 11 to crush construction waste at the same time, the surface of the crushing roller 1 8 and the crushing roller 2 11 can be cleaned to prevent the phenomenon of clogging;

When the rack 14 moves upward, it further drives the piston plate 15 to move upward synchronously. At this time, the inside of the water pumping box 29 is in a negative pressure state. At this time, the water flow in the water storage mechanism external to the water pumping pipe 30 will enter the inside of the water pumping pipe 30, and The one-way valve 1 31 enters the inside of the water pumping box 29 to realize the function of automatic water replenishment, so as to ensure the continuous operation of the dust removal and cleaning functions.
