Detailed implementation mode

[0028] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0029] Embodiment 1:

[0030] As Figures 1 to 5 shown, a crushing device for construction waste recycling includes a crushing unit and a feeding unit.

[0031] The crushing unit includes a crushing box 1. Inside the crushing box 1, a driving crushing roll 15 and a driven crushing roll 16 are movably arranged. The driving crushing roll 15 and the driven crushing roll 16 are located on the same horizontal plane, and there is a gap between the driving crushing roll 15 and the driven crushing roll 16. The top of the crushing box 1 is covered with a cover plate 6, and the cover plate 6 and the crushing box 1 are connected through a connecting component.

[0032] The connecting component includes a first connecting frame 7, a second connecting frame 9 and a positioning gear 10. The positioning gear 10 is arranged at the hinge of the first connecting frame 7 and the second connecting frame 9. The feeding unit includes a lead screw shaft 22. A lead screw collar 23 is meshed on the surface of the lead screw shaft 22. A cross bar 24 is arranged on the surface of the lead screw collar 23. The end of the cross bar 24 is provided with a feeding frame 25. A synchronizing frame 31 is arranged on the side wall of the feeding frame 25. A positioning rack 32 is fixedly arranged at the end of the synchronizing frame 31. The positioning rack 32 and the positioning gear 10 are located on the same vertical plane.

[0033] By providing a feeding unit, when the lead screw shaft inside the feeding unit rotates, it drives the feeding frame to move upward, thereby achieving feeding for the crushing unit. After the feeding frame is about to move to the surface of the crushing box of the crushing unit, the positioning rack and the positioning gear engage, driving the positioning gear to start rotating. The positioning gear is connected to the connecting component, and the connecting component is connected to the cover plate on the top of the crushing box, thereby driving the cover plate to rotate, opening the position of the feeding port. When the feeding is completed, during the reset process, the feeding port is sealed again, ensuring that fine particles will not splash outside the device during the crushing process, and also ensuring that dust will not escape from the feeding port during the crushing process, making the operation safer.

[0034] As Figures 1 to 5 shown, in the specific implementation manner, the first connecting frame 7 is fixedly arranged on the side wall of the cover plate 6, the second connecting frame 9 is fixedly arranged on the surface of the crushing box 1, and a rotating shaft 8 is fixedly arranged through the center of the first connecting frame 7. The two ends of the rotating shaft 8 are movably arranged on the side wall of the second connecting frame 9, and a positioning gear 10 is fixedly arranged at the center position of the rotating shaft 8. The positioning rack 32 moves upward, further pushing the positioning gear 10 to start rotating at this time. After the positioning gear 10 rotates, it will drive the rotating shaft 8 and the first connecting frame 7 to rotate. Since the cover plate 6 is connected to the first connecting frame 7, the cover plate 6 starts to flip, thereby completely opening the feeding port 11.

[0035] As Figures 1 to 5 shown, further, a feeding port 11 is arranged at the top of the crushing box 1. A stepped groove 12 is formed on the surface of the feeding port 11, and the cover plate 6 covers the stepped groove 12. A discharge pipe 14 is arranged at the bottom of the crushing box 1, and the discharge pipe 14 is conical. A pair of guide plates 13 are arranged inside the crushing box 1. There is an interval between the pair of guide plates 13, and the interval is adaptively matched with the interval between the driving crushing roller 15 and the driven crushing roller 16.

[0036] Embodiment 2:

[0037] As Figures 1 to 5 shown, the central shafts of the driving crushing roller 15 and the driven crushing roller 16 movably penetrate through the side wall of the crushing box 1. A driving gear 4 is connected to the end of the central shaft of the driving crushing roller 15, and a driven gear 5 is arranged at the end of the central shaft of the driven crushing roller 16. The driving gear 4 and the driven gear 5 are meshed with each other. A crushing motor 2 is connected to the central shaft of the driving gear 4. A bracket 3 is arranged on the surface of the crushing motor 2, and the bracket 3 is connected to the side wall of the crushing box 1. Start the crushing motor. By rotating the driving gear 4, the driven gear 5 is driven to rotate, and the driving crushing roller 15 and the driven crushing roller 16 connected by the driving gear 4 and the driven gear 5 rotate relatively, achieving the crushing effect.

[0038] As Figures 1 to 5As shown, in the specific implementation, a base plate 17 is movably arranged at the bottom of the lead screw shaft 22. A vertical plate 18 is vertically arranged at the center of the base plate 17. The vertical plate 18 is in a T shape. A lifting motor 21 is arranged on the lower surface of the vertical plate 18. The output shaft of the lifting motor 21 is connected to the lead screw shaft 22. Place the construction waste on the surface of the feeding frame 25. At this time, start the lifting motor 21. The lifting motor 21 drives the lead screw shaft 22 to start rotating. The rotation of the lead screw shaft 22 will drive the lead screw collar 23 and the cross bar 24 to move upward synchronously. After the cross bar 24 moves upward, it drives the feeding frame 25 at the end to move upward synchronously. The upward movement of the feeding frame 25 moves the construction waste towards the feeding port 11.

[0039] As Figures 1 to 5 shown, further, a vertical groove 19 is formed on the surface of the vertical plate 18. An inclined groove 20 is arranged at the end of the vertical groove 19. The height of the end of the inclined groove 20 close to the feeding frame 25 is greater than the height of the other end. A slider 26 is slidably arranged on the surface of the vertical groove 19. A synchronizing rod 27 is fixedly arranged on the surface of the slider 26. A push plate 28 is arranged at the end of the synchronizing rod 27. The push plate 28 is movably inserted into the side wall of the feeding frame 25. When the slider 26 moving synchronously inside the feeding frame 25 moves to the connection of the vertical groove 19, the feeding frame 25 continues to move, causing the slider 26 to move along the inclined groove 20. The push plate 28 is pushed towards the inside of the crushing box 1 through the synchronizing rod 27, so that the waste inside the feeding frame 25 is moved to the opened feeding port 11 through the notch of the baffle 29.

[0040] Embodiment 3:

[0041] As Figures 1 to 5 shown, a sleeve 30 is arranged on the side wall at the bottom of the feeding frame 25. A baffle 29 is movably inserted into the sleeve 30. A groove is formed on the surface of the baffle 29. A positioning protrusion is arranged on the side wall of the crushing box 1. The positioning protrusion corresponds vertically to the groove of the baffle 29. A pair of swing arms 33 are arranged at the bottom of the baffle 29. A sliding sleeve 34 is movably arranged at the end of the pair of swing arms 33. The sliding sleeve 34 is slidably arranged inside a limiting rod 35 arranged inside the sleeve 30. The pair of swing arms 33 are in a V shape. A return spring 36 is horizontally clamped on the side wall of the sliding sleeve 34. The positioning protrusion presses the baffle 29 to move downward. The baffle 29 moves into the sleeve 30. The sliding sleeve 34 is driven to move through the swing arms 33. The return spring 36 is stretched. It is convenient for later resetting through the return spring 36. The baffle 29 moves downward to open one side wall of the feeding frame 25, which is convenient for later discharging operation.

[0042] The implementation principle of a crushing device for recycling construction waste in this embodiment is as follows:

[0043] When the device needs to be used, first reset the device to the initial position, as Figure 2 shown.

[0044] Place the construction waste on the surface of the feeding frame 25. At this time, start the lifting motor 21. The lead screw shaft 22 starts to rotate driven by the lifting motor 21. The rotation of the lead screw shaft 22 will drive the lead screw collar 23 and the cross bar 24 to move upward synchronously. After the cross bar 24 moves upward, it drives the feeding frame 25 at the end to move upward synchronously. The upward movement of the feeding frame 25 moves the construction waste towards the feeding port 11.

[0045] When the feeding frame 25 is about to move to the feeding port 11, the synchronous frame 31 on the side wall of the feeding frame 25 drives the positioning rack 32 to move to the bottom of the positioning gear 10. As the feeding frame 25 continues to move upward, it drives the positioning rack 32 to move upward, and then pushes the positioning gear 10 at this time to start rotating. After the positioning gear 10 rotates, it will drive the rotating shaft 8 and the first connecting frame 7 to rotate. The cover plate 6 is connected to the first connecting frame 7, driving the cover plate 6 to start flipping, thus completely opening the feeding port 11.

[0046] During the movement of the feeding frame 25, the baffle 29 contacts the positioning protrusion. As the feeding frame 25 moves upward, the positioning protrusion presses the baffle 29 to move downward. The baffle 29 moves into the sleeve 30, and drives the sliding sleeve 34 to move through the swing arm 33. The return spring 36 is stretched, which facilitates the later reset. The downward movement of the baffle 29 opens one side wall of the feeding frame 25, facilitating the later discharging operation.

[0047] When the slider 26 moving synchronously inside the feeding frame 25 moves to the connection of the vertical groove 19, the feeding frame 25 continues to move, causing the slider 26 to move along the inclined groove 20. The push plate 28 is pushed into the crushing box 1 through the synchronizing rod 27, so that the garbage inside the feeding frame 25 moves through the notch of the baffle 29 to the opened feeding port 11. Then, the lifting motor 21 rotates in reverse to drive the above structure to reset. Then start the crushing motor. The driving gear 4 rotates, driving the driven gear 5 to rotate. The driving crushing roller 15 and the driven crushing roller 16 connected to the driving gear 4 and the driven gear 5 rotate relatively, achieving the crushing effect.
