[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-3This utility model provides an embodiment of a combined high-efficiency crushing machine for construction waste, comprising a crushing box 1, with crushing shafts 2 rotatably connected to the upper left and right sides of the crushing box 1, and a first crushing roller 3 fixedly connected to the outside of the crushing shafts 2. A collecting hopper 4 is fixedly connected to the lower inside of the crushing box 1, and a second crushing roller 5 is disposed inside the lower inside of the collecting hopper 4. A fixing frame 6 is fixedly connected to the lower middle part of the crushing box 1, and a first motor 7 is fixedly connected to the inner side of the fixing frame 6. A transmission shaft 8 is fixedly connected to the drive end of the first motor 7, and the upper end of the transmission shaft 8 is fixedly connected to the inside of the second crushing roller 5. The crushing box 1 is provided with meshing driven gears 21 on both the front and rear sides. The middle part of the driven gears 21 is fixedly connected to the outer side of the end of the crushing shaft 2. The upper front side of the crushing box 1 is fixedly connected with an L-shaped plate 23. The lower front side of the L-shaped plate 23 is fixedly connected with a second motor 24. The drive end of the second motor 24 is fixedly connected with a drive gear 25. The outer side of the drive gear 25 is meshed with the outer side of the driven gear 21. The upper inner wall of the crushing box 1 is fixedly connected with guide plates 26 on both the left and right sides. The bottom of the crushing box 1 is located at the bottom of the second crushing roller 5 and has discharge ports at both the front and rear ends.

[0019] When construction waste is fed into the device from the top, the guide plates 26 fixed on the left and right sides of the upper inner wall of the crushing box 1 guide the fed waste between the two first crushing rollers 3, preventing the waste from accumulating or shifting inside the crushing box. The second motor 24 fixed at the lower end of the L-shaped plate 23 on the upper front side of the crushing box 1 is started, and its drive end drives the drive gear 25 to rotate. Since the drive gear 25 meshes with the driven gear 21, it drives the two driven gears 21 to rotate in opposite directions, thereby driving the crushing shaft 2 and the externally fixed first crushing rollers 3 to rotate relative to each other. The coordinated rotation of the two first crushing rollers 3 can initially crush the guided construction waste, and initially crush large and irregular pieces of decoration waste. The pulverized construction waste falls downwards under gravity into the collection hopper 4 fixed inside the lower end of the pulverizing box 1. The collection hopper 4 is funnel-shaped and can quickly collect the material after the initial pulverization and guide it precisely to the crushing area between the collection hopper 4 and the second pulverizing roller 5. The first motor 7 inside the fixed frame 6 at the lower middle of the pulverizing box 1 is started, and its drive end drives the second pulverizing roller 5 to rotate through the transmission shaft 8. The second pulverizing roller 5 cooperates with the inner wall of the collection hopper 4 to perform secondary crushing on the material after the initial pulverization. The fine construction waste particles that have completed secondary crushing will be naturally discharged from the discharge port at the bottom of the pulverizing box 1 located at the front and rear ends of the second pulverizing roller 5, thereby improving the pulverization effect and efficiency of the waste.

[0020] Reference Figure 1 , Figures 4-6The crushing box 1 has lifting plates 19 on both the front and rear sides. Movable slots 20 are formed on both the left and right sides of the middle of the lifting plates 19. An eccentric shaft 22 is movably connected inside the movable slots 20. The rear end of the eccentric shaft 22 is fixedly connected to the inside of the driven gear 21. Water tanks 9 are fixedly connected to the left and right sides of the crushing box 1. A U-shaped plate 10 is provided at the upper end of the water tank 9. The lower end of the U-shaped plate 10 is fixedly connected to the upper side of the lifting plates 19. A movable sleeve 11 is fixedly connected to the middle of the upper end of the U-shaped plate 10. The upper end of the movable sleeve 11 is fixedly... A conduit 12 is fixedly connected, and a first one-way valve 13 is fixedly connected to the upper end of the conduit 12. A nozzle 14 is fixedly connected to the upper end of the first one-way valve 13. A piston 15 is movably connected inside the movable sleeve 11. A second one-way valve 16 is fixedly connected to the middle of the piston 15. A fixed pipe 17 is fixedly connected to the lower side of the second one-way valve 16. The lower end of the fixed pipe 17 is fixedly connected to the bottom of the inner wall of the water tank 9. Water inlets 18 are opened on both the front and rear sides of the lower end of the fixed pipe 17. The water inlets 18 are connected to the second one-way valve 16.

[0021] While the second motor 24 drives the driven gear 21 to rotate to achieve initial crushing, the eccentric shaft 22 fixed inside the driven gear 21 will rotate synchronously with the driven gear 21. Since the eccentric shaft 22 is movably connected in the movable groove 20 in the middle of the lifting plates 19 on both sides of the crushing box 1, the rotating eccentric shaft 22 will make eccentric movements in the movable groove 20, thereby driving the lifting plate 19 to move up and down reciprocally in the vertical direction. When the lifting plate 19 moves up and down, it will drive the U-shaped plate 10 fixed at its upper end and the movable part in the middle of the upper end of the U-shaped plate 10. The sleeve 11 moves up and down synchronously. When the movable sleeve 11 moves upward, the piston 15 inside it moves downward relative to the movable sleeve 11, causing a negative pressure environment to be formed inside the movable sleeve 11. At this time, the water in the water tanks 9 fixed on the left and right sides of the crushing box 1 will enter the fixed pipe 17 through the water inlet 18 opened on the front and rear sides of the lower end of the fixed pipe 17, and then flow into the movable sleeve 11 for storage through the second one-way valve 16. The one-way conduction characteristic ensures that water can only flow from the fixed pipe 17 to the movable sleeve 11, preventing water in the movable sleeve 11 from flowing back to the water tank 9, thus ensuring the stability and effectiveness of the water suction process. When the movable sleeve 11 moves downward with the lifting plate 19, the piston 15 moves upward relative to the movable sleeve 11. At this time, the second one-way valve 16 closes, preventing water from flowing back into the movable sleeve 11. As the movable sleeve 11 continues to descend, its internal space is compressed by the piston 15, causing the internal water pressure to rise rapidly. High-pressure water will flow through the movable sleeve. The upper end of the 11 is connected to the conduit 12, which passes through the first one-way valve 13 at the upper end of the conduit 12 and finally sprays out at high speed from the nozzle 14. The first one-way valve 13 ensures that the water flow can only flow from the conduit 12 to the nozzle 14. The water spraying direction of the nozzle 14 is precisely aimed at the crushing area of ​​the first crushing roller 3 and the construction waste. The sprayed water mist can quickly adsorb the dust generated during the crushing process, effectively inhibit the spread of dust, improve the working environment, protect the health of the operators, and at the same time avoid dust from causing wear to the internal parts of the equipment and extend the service life of the equipment.

[0022] Working principle: Construction waste is fed into the device from the top. The guide plate 26 directs the waste between the two first crushing rollers 3. The second motor 24 drives the drive gear 25 to rotate. The rotating drive gear 25 engages with the driven gear 21, driving the two first crushing rollers 3 to rotate, initially crushing the waste. The initially crushed waste falls downwards into the collection hopper 4 between the second crushing roller 5. The first motor 7 drives the second crushing roller 5 to rotate via the transmission shaft 8, further crushing the construction waste. Finally, the waste is discharged from the outlet at the bottom of the crushing box 1. Simultaneously, the second motor 24 drives the driven gear 21 to rotate, which in turn drives the eccentric shaft 22 to rotate, causing it to move within the movable groove 20. This moves the lifting plate 19 up and down. 19 and U-shaped plate 10 drive the movable sleeve 11 to move up and down. When the movable sleeve 11 moves upward, the piston 15 moves downward inside the movable sleeve 11, creating a negative pressure inside the movable sleeve 11. This allows water from the water tank 9 to enter the movable sleeve 11 through the inlet 18 at the lower end of the fixed pipe 17 and through the second one-way valve 16. When the movable sleeve 11 descends, the piston 15 moves upward relative to the movable sleeve 11. At this time, the second one-way valve 16 prevents the water inside from passing through. When the movable sleeve 11 descends, it cooperates with the piston 15 to compress the internal space, allowing the water stored inside to pass through the conduit 12 and the first one-way valve 13 and be sprayed out from the nozzle 14, spraying towards the first crushing roller 3 and the waste, reducing the dust generated during the crushing process.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
