Example

[0020] A fixing rod 19 is fixedly connected below the linkage shaft 27, a piston head 20 is fixedly connected below the fixing rod 19, the piston head 20 penetrates and is connected to the inside of the water tank 17, one end of the linkage shaft 27 is fixedly connected to a connecting plate 10, and one end of the connecting plate 10 is fixedly connected to a rack 11.

[0021] A feed port 2 is provided above the processing body 1, and two groups of baffles 3 are slidably connected to the feed port 2. A rotating shaft 5 is fixedly connected to one side of each group of baffles 3, and a connecting rod 6 is rotatably connected to the inside of each group of rotating shafts 5. The other end of each group of connecting rods 6 is rotatably connected to the inside of both sides of the supporting shaft 7. A half gear 12 is rotatably connected to the rear of the processing body 1.

[0022] The working principle of the waste treatment device for construction engineering according to the first embodiment is as follows: when construction waste is to be crushed, the material is first put into the feed port 2, and then the main motor 16 is started. The rotation of the main motor 16 drives the two sets of rotating shafts 14 to rotate through the third V-belt 18 and the second V-belt 15. The rotating shaft 14 is fixedly connected to the crushing roller 26. At this time, the crushing roller 26 will also rotate together. Then, one set of rotating shafts 14 is connected to the half gear 12 through the first V-belt 13 to rotate. The rotation of the half gear 12 drives the rack 11 to move downward, and the rack 11 moves downward. The bar 11 is fixedly connected to the linkage shaft 27 through the connecting plate 10. At this time, the linkage shaft 27 will move downward under the drive of the half gear 12. Then, the linkage shaft 27 moving downward causes the two groups of baffles 3 to move to both sides through the connecting rod 6, so that the construction waste inside the baffle 3 falls into the interior of the processing body 1 for crushing. When the half gear 12 rotates to the position where the teeth are missing, the half gear 12 no longer meshes with the rack 11. At this time, the linkage shaft 27 will be reset under the elastic force of the reset spring 8. At this time, the two groups of baffles 3 will close, and intermittent feeding of materials into the interior of the processing body 1 can be realized to prevent the machine from getting stuck and damaged.

[0026] The working principle of the waste treatment device for construction projects based on Example 2 is: by setting a fixed rod 19, when the linkage shaft 27 moves downward, the fixed rod 19 will bring the piston head 20 to squeeze into the water tank 17, so that the water pressure inside the water tank 17 increases, and then the water inside the water tank 17 will be transmitted to the nozzle 25 through the water pipe 4, and finally sprayed by the nozzle 25, when the linkage shaft 27 rises, the ball 23 can move downward with the telescopic spring 22, and then the water tank 17 will be connected to the outside, so that the air pressure inside the water tank 17 can be restored to normal for the next spraying, and the material can be sprayed before it goes down to prevent dust from being generated when it is crushed, and the inside of the processing body 1 can also be cooled to prevent heat accumulation inside the processing body 1 during long-term operation, which may cause damage to the machine.
