This prevents large pieces of construction waste from blocking the channels in the frame and ensures unobstructed flow within the device.

[0018] 3. This invention uses a connecting rod to move a moving frame synchronously. The moving frame uses a magnet to adsorb and screen metal materials in construction waste. When the moving frame moves to the right, the toothed comb of the mounting frame scrapes off the metal materials adsorbed on the magnet, thereby achieving unified collection of metal materials and improving the treatment effect of construction waste.

[0019] 4. In this invention, the moving frame moves the slider synchronously along the corresponding guide column, and the top ball inside the slider pushes the guide column to rotate the fan blades, thereby blowing the dust and light materials mixed in the construction waste toward the light material collection frame. The filter frame is used to screen the blown dust and light materials, thereby achieving the classification and treatment of construction waste. Attached Figure Description

Detailed Implementation

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0032] Example 1: A construction waste shredder, referencedFigures 1-3 As shown, the machine includes a frame 1, a hopper 101, a guide plate 102, and an integrated controller 107. The hopper 101 is welded to the top surface of the frame 1. The integrated controller 107 is bolted to the lower front part of the frame 1. The guide plate 102, adapted to guide construction waste, is located in the middle of the frame 1. The machine also includes a drive assembly, a compaction roller 105, an electric conveyor belt 108, a top block 109, a screen frame 1010, and a screw feeder 1011. The lower inner part of the frame 1 is symmetrically equipped with crushing rollers 105 adapted to crush construction waste. The crushing rollers 105 are located to the lower left of the guide plate 102, and the guide plate 102 is inclined towards the crushing rollers 105. The drive assembly is used to drive the crushing rollers 105. The lower inner part of the frame 1 is equipped with an electric conveyor belt 108 electrically connected to the integrated controller 107. The electric conveyor belt 108 is located below the crushing rollers 105. The electric conveyor belt 108 will transport the crushed construction waste to the lower inner part of the frame 1. Construction waste is conveyed out of the frame 1. A number of top blocks 109 are symmetrically arranged circumferentially on the electric conveyor belt 108. A flip-up screen frame 1010 is located on the lower left side of the frame 1. The screen frame 1010 is positioned between the crushing roller 105 and the electric conveyor belt 108, and is tilted downwards to the right. The screen frame 1010 screens the construction waste after it has been crushed by the crushing roller 105. Waste that meets the crushing standard passes through the screen frame 1010 and falls into the ground. On the electric conveyor belt 108, when the electric conveyor belt 108 moves, the top block 109 will abut against the screen frame 1010. The inner lower part of the frame 1 is symmetrically installed with bolts with screw feeders 1011 that are electrically connected to the integrated controller 107. The openings at the lower ends of the two screw feeders 1011 are flush with the top surface of the screen frame 1010. Construction waste that does not pass through the screen frame 1010 will be fed back into the crushing roller 105 by the screw feeders 1011 for secondary crushing.

[0033] refer to Figure 2 and Figure 3 As shown, the drive assembly includes a stepper motor 103, a gear set 104, and a pulley set 106. The stepper motor 103, which is electrically connected to the integrated controller 107, is bolted to the lower inner part of the frame 1. The output shaft of the stepper motor 103 is connected to the left rolling roller 105 via a coupling. The front end of the left rolling roller 105 is provided with a gear set 104, and the front end of the two rolling rollers 105 is provided with a pulley set 106. The pulley set 106 is fixedly connected to the gear set 104. When the left rolling roller 105 rotates, it will drive the right rolling roller 105 to rotate in the opposite direction through the gear set 104 and the pulley set 106.

[0034] When construction waste needs to be crushed, the crushing program is first started via the integrated controller 107. The integrated controller 107 will start the stepper motor 103, the electric conveyor belt 108, and the screw feeder 1011. The output shaft of the stepper motor 103 will drive the left crushing roller 105 to rotate clockwise, and through the gear set 104 and the pulley set 106, drive the right crushing roller 105 to rotate counterclockwise. Then, the construction waste to be processed is poured into the hopper 101. The construction waste will fall onto the two crushing rollers 105 along the inclined surface of the guide plate 102. The two crushing rollers 105 will crush the construction waste. The crushed construction waste will fall onto the screen frame 1010 for screening. The shredded construction waste falls onto the electric conveyor belt 108, which transports the shredded construction waste out of the frame 1. As the electric conveyor belt 108 moves, the top block 109 on the electric conveyor belt 108 sequentially pushes the screen frame 1010, causing the screen frame 1010 to deflect and vibrate. This shakes the large pieces of construction waste remaining on the screen frame 1010 into the screw feeder 1011. The screw feeder 1011 then transports the remaining large pieces of construction waste back to the crushing roller 105 for secondary crushing, thereby ensuring the crushing effect of the construction waste, improving the crushing quality, and thus cyclically processing the construction waste.

[0035] Example 2: Based on Example 1, refer to Figure 1 and Figure 4 As shown, it also includes a pre-compacting assembly. The hopper 101 is equipped with a pre-compacting assembly for pre-crushing construction waste. The pre-compacting assembly includes a support frame 2, a dual-head motor 3, a cam 4, a connecting rod 5, a hinge rod 6, a movable compaction plate 8, and a fixed compaction plate 9. The support frame 2 is welded to the right side of the hopper 101. The dual-head motor 3, which is electrically connected to the integrated controller 107, is bolted to the center of the support frame 2. The two output shafts of the dual-head motor 3 are respectively connected to the cam 4 via couplings. The upper parts of the two cams 4 are rotatably connected to the connecting rods. 5. When the cam 4 rotates, it will drive the connecting rod 5 to move. The two connecting rods 5 are respectively rotatably connected to the hinge rods 6. The right ends of the two hinge rods 6 are respectively rotatably connected to the support frame 2. The inner left side wall of the hopper 101 is equipped with a fixed rolling plate 9 by bolts. The inner right side wall of the hopper 101 is provided with a movable rolling plate 8 that can rotate toward the fixed rolling plate 9. The left ends of the two hinge rods 6 pass through the right side wall of the hopper 101 and are rotatably connected to the lower right side of the movable rolling plate 8. The hinge rods 6 will push the movable rolling plate 8 to deflect toward the fixed rolling plate 9.

[0036] When construction waste is poured into the hopper 101, the dual-head motor 3 is started by the integrated controller 107. The two output shafts of the dual-head motor 3 drive the corresponding cams 4 to rotate. The two cams 4 will push the corresponding hinge rods 6 through the connecting rods 5 to repeatedly deflect upward and downward, thereby driving the movable crushing plate 8 to move closer to and away from the fixed crushing plate 9. When the movable crushing plate 8 moves closer to the fixed crushing plate 9, it will crush the construction waste in the hopper 101, thereby pre-crushing the construction waste and preventing large pieces of construction waste from blocking the channel in the frame 1.

[0037] refer to Figure 1 , Figure 5 and Figure 6 As shown, it also includes a blowing assembly. The middle of the frame 1 is equipped with a blowing assembly for screening dust and other impurities. The blowing assembly includes a mounting base 10, a push rod 11, guide rails 12, a slider 13, guide posts 14, a top ball 15, and fan blades 16. A mounting base 10 is welded to the middle of the right side of the frame 1. Three guide rails 12 are bolted to the right side of the mounting base 10. Three rotatable guide posts 14 are located on the right side of the mounting base 10, each guide post 14 being positioned within its corresponding guide rail 12, and each guide post 14 is divided into... Each guide post 14 has a spiral groove 14a. The left end of the guide post 14 is bolted with a fan blade 16. The fan blade 16 is located inside the frame 1 and directly to the right of the guide plate 102. When the guide post 14 rotates, it will drive the fan blade 16 to blow air to the guide plate 102. Each guide rail 12 is provided with a slider 13 that can slide left and right along the corresponding guide post 14. Each slider 13 is provided with a top ball 15. The top ball 15 will push the guide post 14 to rotate through the corresponding spiral groove 14a. A push rod 11 is welded between the sliders 13.

The mounting frame 27 is welded to the middle of the right side of the frame 1. A toothed comb is installed inside the mounting frame 27. Guide rods 29 are symmetrically welded to the upper right side of the mounting frame 27. A movable frame 28, which can slide left and right along the mounting frame 27, is installed inside the mounting frame 27. The movable frame 28 is connected to the push rod 11 by welding, and the movable frame 28 is slidably connected to the two guide rods 29. A return spring 2901 is provided between the guide rod 28 and the guide rod 29. A magnet 30 is bolted to the left side of the movable frame 28. The magnet 30 is located inside the frame 1. The magnet 30 will attract metal materials in the construction waste and will move along the toothed comb of the mounting frame 27. The toothed comb will scrape off the metal materials attracted on the magnet 30. A metal collection frame 3001 that can be pulled out from the right side of the frame 1 is provided in the lower inner part of the mounting frame 27. The metal collection frame 3001 is located directly below the magnet 30 and the toothed comb of the mounting frame 27. The scraped metal materials will fall into the metal collection frame 3001 for collection.

[0039] refer to Figure 1 , Figure 4 and Figure 9 As shown, it also includes movable rods 501. The right side of the movable frame 28 is symmetrically connected to the movable rods 501 in a rotating manner. The upper ends of the two movable rods 501 are respectively rotatably connected to the connecting rods 5 on the same side. When the connecting rods 5 move, they will drive the movable frame 28 to move synchronously through the movable rods 501.

[0040] As the connecting rod 5 moves, the connecting rod 5 will drive the moving frame 28 to move back and forth to the left and right along the two guide rods 29 via the movable rod 501. During this period, the return spring 2901 will elastically assist the moving frame 28 in resetting, thereby ensuring the smooth movement of the moving frame 28. When the moving frame 28 moves to the left, the magnet 30 will be inserted into the frame 1 along the toothed comb of the mounting frame 27. The magnet 30 will adsorb and screen the metal material in the construction waste falling from the hopper 101 through its magnetism. When the moving frame 28 moves to the right, the toothed comb of the mounting frame 27 will scrape off the metal material adsorbed on the magnet 30, so that the metal material falls into the metal collection frame 3001 for unified collection.

[0041] refer to Figure 1 and Figure 8As shown, it also includes a screening component. The inner left part of the frame 1 is provided with a screening component for screening dust and other impurities and other light materials. The screening component includes a mounting frame 21, a handle 22, a transparent plate 23, a light material collection frame 24, a filter frame 25, and a discharge hopper 26. The mounting frame 21 is welded to the inner left part of the frame 1. The mounting frame 21 is located to the upper left of the crushing roller 105. The inner right part of the mounting frame 21 is provided with a light material collection frame 24 that can be removed from the frame 1. The top surface of the light material collection frame 24 is provided with an observation surface. The transparent panel 23 inside the light material collection frame 24 has a handle 22 bolted to its top surface. The handle 22 makes it easy to remove the light material collection frame 24 from the mounting frame 21. The light material collection frame 24 has a through hole on its right side, which is flush with the fan blade 16. The light material collection frame 24 has a detachable filter frame 25 on its left side. The filter frame 25 filters dust and light materials. The bottom left side of the mounting frame 21 has a discharge hopper 26 that passes through the frame 1.

[0042] As the moving frame 28 moves back and forth to the left and right, it drives the three sliders 13 to move synchronously along the corresponding guide rails 12 and guide posts 14 via the push rod 11. When the slider 13 moves to the right, it pushes the spiral groove 14a through the top ball 15, causing the guide post 14 to rotate. This causes the guide post 14 to drive the fan blades 16 to rotate synchronously. As the fan blades 16 rotate, they blow the construction waste moving along the guide plate 102. The dust and lightweight impurities mixed in the construction waste are then blown towards the lightweight materials. The light material collection frame 24 is blown in a certain direction. The filter frame 25 inside the light material collection frame 24 will screen the dust and light materials and other impurities blown in. Small particles of dust and other impurities will pass through the filter frame 25 and be discharged from the discharge hopper 26. The remaining light materials and other impurities that cannot pass through the filter frame 25 will be stored and collected in the light material collection frame 24. During this period, the storage status in the light material collection frame 24 can be observed in real time through the transparent plate 23. When the light material collection frame 24 is full, it can be pulled out from the mounting frame 21 by the handle 22 for cleaning.

[0043] refer to Figure 1 and Figure 7 As shown, it also includes a pressing assembly. The hopper 101 is equipped with a pressing assembly for pressing down the construction waste. The pressing assembly includes a fixed plate 17, a pressing plate 18, a counterweight 19, and a top rod 20. Fixed plates 17 are symmetrically welded to the front and back of the top surface of the hopper 101. The pressing plates 18 are rotatably installed on the two fixed plates 17 respectively. The counterweight 19 is bolted to the top surface of the two pressing plates 18 respectively. The pressing plates 18 will press down the construction waste in the hopper 101 under the action of the counterweight 19 and gravity. The top rod 20 is welded to the left side of the two pressing plates 18 respectively.

[0044] refer to Figure 1 and Figure 10 As shown, it also includes a feeding assembly. The left side of the frame 1 is provided with a feeding assembly for lifting and adding construction waste to the downward hopper 101. The feeding assembly includes a fixed frame 31, a servo motor 32, a toothed chain belt assembly 33, and a loading frame 35. The fixed frame 31, which is inclined towards the downward hopper 101, is bolted to the left side of the frame 1. The upper part of the fixed frame 31 is symmetrically bolted with servo motors 32 that are electrically connected to the integrated controller 107. The fixed frame 31 is symmetrically provided with toothed chain belt assemblies. 33. The upper part of the two toothed chain belt assembly 33 is connected to the output shaft of the servo motor 32 on the same side through a coupling. A loading frame 35 with a material drop hole 35a on the lower right is installed between the two toothed chain belt assemblies 33 by bolts. The loading frame 35 is in contact with the inclined surface of the fixed frame 31. When the loading frame 35 feeds material upward, the inclined surface of the fixed frame 31 will block the material drop hole 35a. When the loading frame 35 moves upward, it will abut against the two push rods 20. The loading frame 35 will push the push rods 20 to make the two pressing plates 18 rotate upward and open.

[0045] refer to Figure 1 As shown, it also includes a baffle plate 36. The baffle plate 36 is bolted to the right side of the top surface of the hopper 101. The baffle plate 36 will block the construction waste and prevent the construction waste from splashing outward from the right side of the hopper 101.

[0046] When feeding material into the hopper 101, the construction waste to be crushed is first poured into the loading frame 35. At this time, the discharge hole 35a of the loading frame 35 is blocked by the fixing frame 31. Then, the servo motor 32 is started by the integrated controller 107. The two servo motors 32 drive the corresponding toothed chain belt group 33 to rotate. The two toothed chain belt groups 33 drive the loading frame 35 to move towards the hopper 101. As the loading frame 35 moves upward, it first pushes the two push rods 20, thereby causing the corresponding pressing plate 18 to flip upward and open through the push rods 20, thus opening the hopper 101. When the loading frame 35 moves onto the hopper 101, the material falls... When the material hole 35a is no longer blocked by the fixing frame 31, the construction waste in the loading frame 35 will fall into the hopper 101 from the material hole 35a. During this period, the baffle plate 36 will block the construction waste to prevent it from splashing out from the right side of the hopper 101, thus completing the automatic feeding into the hopper 101. When the push rod 20 loses contact with the loading frame 35, the pressing plate 18 will press the construction waste in the hopper 101 under the action of the counterweight 19 and gravity, preventing the construction waste from being pushed out of the hopper 101. At the same time, it can also assist the movable rolling plate 8 in pre-compacting the construction waste, thus ensuring the smooth flow in the hopper 101.

[0047] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
