Technical Field

[0001] The present application relates to the technical field of construction waste recycling, and in particular to a construction waste recycling device and process. Background Art

[0002] Construction waste refers to the slag, abandoned soil, abandoned materials, silt and other waste generated during the construction, laying, demolition and repair of various buildings, structures, pipelines, etc. by construction units or individuals. After the construction workers complete the construction, a large amount of construction waste will be left at the construction site. Most of the construction waste still has recycling value, so it needs to be recycled. The main recycling method is to use crushing equipment to break it up so that it is easier to screen out useful materials.

[0003] Existing crushing equipment mainly crushes construction waste by rotating two crushing rollers in opposite directions. However, when crushing relatively smooth cylindrical construction waste, the relatively smooth cylindrical construction waste will roll over between the two crushing rollers and cannot be crushed, which hinders the crushing of construction waste.

[0007] By adopting the above technical solution, the construction waste is transported to the feed hopper. After a proper amount of construction waste is placed in the feed hopper, the pressure plate is moved downward along the arc-shaped transition plate. Under the guidance of the arc-shaped transition plate, the pressure plate moves into the feed hopper and abuts against the construction waste, so that the cylindrical or relatively smooth construction waste is in close contact with the crushing mechanism, thereby reducing the flipping and rolling of the construction waste in the feed hopper, so as to facilitate the crushing of the construction waste.

[0014] Optionally, a storage hopper is provided on the box body, and the storage hopper is connected with the feed hopper. An opening and closing plate is provided on the storage hopper for opening and closing the connecting channel between the storage hopper and the feed hopper. When the pressure plate is located in the feed hopper, the opening and closing plate closes the connecting channel between the storage hopper and the feed hopper. An adjustment component for adjusting the position of the opening and closing plate is provided on the box body.

[0015] By adopting the above technical scheme, construction waste is continuously transported to the storage hopper for temporary storage. When loading is required, the connection channel between the storage hopper and the feed hopper is opened by adjusting the opening and closing plate through the adjustment component, and the construction waste temporarily stored in the storage hopper is put into the feed hopper, thereby reciprocatingly filling the feed hopper, which is also conducive to continuously inputting construction waste into the storage hopper and avoiding repeated shutdowns.

[0019] By adopting the above technical solution, when the pressure plate slides downward to press the construction waste, the rope winder drives the rack to slide through the first gear while rotating, the rack drives the second gear to rotate, the second gear drives the transmission shaft to rotate, and the transmission shaft drives the lead screw to rotate through the second bevel gear, thereby driving the opening and closing plate to rise. When the pressure plate is located at the connection between the feed hopper and the arc-shaped transition plate, the second gear separates from the rack, the opening and closing plate is fully extended to close the passage between the feed hopper and the storage hopper, the rope winder continues to release the connecting rope, and the pressure plate continues to slide down into the feed hopper; when the construction waste in the feed hopper After the crushing is completed, the rope winder is reversed and the connecting rope is retracted.

When the pressure plate slides downward to press the construction waste, the rope reel drives the rack to slide through the first gear while rotating, the rack drives the second gear to rotate, the second gear drives the transmission shaft to rotate, and the transmission shaft drives the lead screw to rotate through the second bevel gear, thereby driving the opening and closing plate to rise. When the pressure plate is located at the connection between the feed hopper and the arc-shaped transition plate, the second gear separates from the rack, the opening and closing plate is fully extended to close the passage between the feed hopper and the storage hopper, the rope reel continues to release the connecting rope, and the pressure plate continues to slide down into the feed hopper; when the construction waste in the feed hopper is crushed, Finally, reverse the rope winder and retract the connecting rope, which drives the pressure plate to slide upward. When the pressure plate moves upward to the bottom of the arc-shaped transition plate, the rack meshes with the second gear, thereby rotating the lead screw in the opposite direction to lower the opening and closing plate.

[0038] The following is combined with Figure 1-5 This application is described in further detail.

[0039] The present application embodiment discloses a construction waste recycling device. Figure 1 and Figure 2 The construction waste recycling equipment includes a box body 1, in which a crushing mechanism for crushing construction waste is installed, and the crushing mechanism includes two crushing rollers 21, which are rotatably connected in the box body 1, and the ends of the two crushing rollers 21 are fixedly installed with third gears 22, and the two third gears 22 are meshed with each other. A motor 24 for driving a third gear 22 to rotate is bolted and fixed on the box body 1, and the output shaft of the motor 24 is connected to a third gear 22. A partition 23 is welded and fixed in the box body 1, and one end of the two crushing rollers 21 away from the motor 24 is rotatably connected to the partition 23. A feed hopper 2 is welded and fixed on the top of the box body 1, and the feed hopper 2 is connected to the box body 1. The feed hopper 2 is located directly above the two crushing rollers 21; a discharge port is opened at the bottom of the box body 1.

[0040] Reference Figure 1 The feed hopper 2 is welded and fixed with arc-shaped transition plates 3 on two opposite sides along the length direction. The two arc-shaped transition plates 3 extend from the side away from the feed hopper 2 to the side away from each other. The two arc-shaped transition plates 3 are slidably connected with a pressing plate 4 on the side close to each other. The pressing plate 4 is used to squeeze the construction waste in the feed hopper 2. The pressing plate 4 slides along the arc-shaped surface of the arc-shaped transition plate 3. The pressing plate 4 slides to the bottom of the feed hopper 2. Two driving components for driving the pressing plate 4 to slide are provided on the box body 1, and the two driving components are respectively located on both sides of the box body 1.

[0041] Reference Figure 1 and Figure 2 The width of the pressing plate 4 is equal to one-half of the internal width of the feed hopper 2. The end of the pressing plate 4 away from the arc-shaped transition plate 3 is rounded. When both pressing plates 4 are located in the feed hopper 2, the sides of the two pressing plates 4 abut against each other. After the two pressing plates 4 move into the feed hopper 2, they abut against each other, thereby closing the feed hopper 2 and reducing the dust flying from the feed hopper 2 to the outside during the crushing process, so as to reduce the pollution to the environment.

[0042] Reference Figure 2 , Figure 3 and Figure 4 The driving assembly includes a guide rod 5, an elastic member and a recovery member. A slide groove 6 is provided on the arc-shaped transition plate 3. The slide groove 6 extends to the bottom of the side wall of the feed hopper 2. The guide rod 5 is located in the slide groove 6. The guide rod 5 is an arc-shaped rod adapted to the arc-shaped transition plate 3. A connecting block 25 is welded and fixed on the pressing plate 4. The connecting block 25 is slidably connected in the slide groove 6. The slide groove 6 is a T-shaped groove. The connecting block 25 is a T-shaped block adapted to the slide groove 6. One side of the pressing plate 4 close to the connecting block 25 abuts against the arc-shaped transition plate 3. The connecting block 25 is slidably sleeved on the guide rod 5. The elastic member is used to drive the pressing plate 4 to slide toward one side of the feed hopper 2. The recovery member is used to retract the pressing plate 4 to the top of the arc-shaped transition plate 3.

[0043] Reference Figure 4 and Figure 5 The elastic member includes a spring 7 sleeved on the guide rod 5 for driving the pressing plate 4 to slide toward the feed hopper 2. One end of the spring 7 abuts against the top wall of the slide 6, and the other end abuts against the connecting block 25. When the pressing plate 4 moves to the bottom of the feed hopper 2, the spring 7 is still in a compressed state. The recovery member includes a rope winding machine 8 fixedly mounted on the side wall of the box body 1. The rope winding machine 8 is driven by a stepping motor. A connecting rope 27 is wound around the rope winding machine 8. The connecting rope 27 passes around the top of the arc-shaped transition plate 3 and is fixedly connected to the pressing plate 4. In other embodiments, a pulley can be installed on the top of the arc-shaped transition plate 3, and the connecting rope 27 passes through the pulley to connect with the pressing plate 4, thereby reducing the wear of the connecting rope 27.

[0044] When in use, the rope reel 8 releases the connecting rope 27, and the spring 7 drives the pressing plate 4 to slide downward, so that the pressing plate 4 always keeps in contact with the construction waste and presses down, reducing the rolling of the construction waste, so as to facilitate the crushing of the construction waste. When it is necessary to move the pressing plate 4 back, the rope reel 8 is started, the rope reel 8 drives the connecting rope 27 to be retracted, and the connecting rope 27 pulls the pressing plate 4 to move upward, compresses the spring 7, and the pressing plate 4 slides along the arc-shaped transition plate 3, so that when the pressing plate 4 moves to the top of the arc-shaped transition plate 3, the feed hopper 2 is opened to facilitate feeding again.

[0045] Reference Figure 1 and Figure 3 A storage hopper 9 is welded and fixed on the box body 1. The storage hopper 9 is located at one end of the feed hopper 2, and the storage hopper 9 is connected to the feed hopper 2. An opening and closing plate 10 for opening and closing the connecting channel between the storage hopper 9 and the feed hopper 2 is slidably connected to the storage hopper 9. A placement groove 13 is provided on the box body 1. The opening and closing plate 10 is located in the placement groove 13. When the opening and closing plate 10 is completely moved into the placement groove 13, the top surface of the opening and closing plate 10 is flush with the bottom surface of the storage hopper 9, and the opening and closing plate 10 slides in the vertical direction. When the pressure plate 4 moves out of the placement groove 13, the opening and closing plate 10 closes the connecting channel between the storage hopper 9 and the feed hopper 2. The placement groove 13 is located on the side of the partition 23 away from the crushing roller 21. The placement groove 13 is partially opened on the partition 23. An adjustment component for adjusting the position of the opening and closing plate 10 is provided on the box body 1.

[0046] The construction waste is continuously transported to the storage hopper 9 for temporary storage. When loading is required, the opening and closing plate 10 is adjusted to open the connection channel between the storage hopper 9 and the feed hopper 2, and the construction waste temporarily stored in the storage hopper 9 is put into the feed hopper 2, thereby reciprocatingly filling the feed hopper 2, which is conducive to continuously inputting the construction waste into the storage hopper 9 and avoiding repeated shutdowns.

[0047] Reference Figure 3The adjustment component includes a screw 11 rotatably connected to the box body 1, and the rotation axis of the screw 11 is along the vertical direction. Two screws 11 are provided, and the two screws 11 are respectively located on both sides of the opening and closing plate 10 close to the rope winding machine 8. Slide blocks 12 are threadedly sleeved on the two screws 11. The slide blocks 12 are located in the placement groove 13 and abut against the side walls in the placement groove 13 to limit the rotation of the slide blocks 12; the opening and closing plate 10 is fixed on the two slide blocks 12, and an adjusting member for rotating the screw 11 is provided on the box body 1.

[0048] Reference Figure 2 and Figure 5 The adjusting member includes a first gear 14 fixedly sleeved on the rotating shaft of the rope winding machine 8, and the first gear 14 rotates with the rope winding machine 8. A rack 15 is slidably connected to the box body 1, and the sliding direction of the rack 15 is parallel to the rotating axis direction of the crushing roller 21. The first gear 14 meshes with the rack 15. A slide rail 26 is welded and fixed to the box body 1, and the rack 15 is slidably placed in the slide rail 26. A transmission shaft 16 is rotatably connected to the box body 1, and a second gear 17 for meshing with the rack 15 is fixedly sleeved at one end of the transmission shaft 16, and a first bevel gear 18 is fixedly sleeved at the other end. A second bevel gear 19 is fixedly sleeved at the bottom of the lead screw 11, and the second bevel gear 19 meshes with the first bevel gear 18. When the pressing plate 4 is located at the connection between the feed hopper 2 and the arc-shaped transition plate 3, the second gear 17 is separated from the rack 15, and the opening and closing plate 10 closes the passage between the feed hopper 2 and the storage hopper 9; when the pressing plate 4 moves upward to the top of the arc-shaped transition plate 3, the opening and closing plate 10 opens the passage between the feed hopper 2 and the storage hopper 9.

[0049] When the pressing plate 4 slides downward to press the construction waste, the rope winder 8 releases the connecting rope 27, and the pressing plate 4 slides downward under the action of the spring 7. While rotating, the rope winder 8 drives the rack 15 to slide through the first gear 14, and the rack 15 drives the second gear 17 to rotate, and the second gear 17 drives the transmission shaft 16 to rotate, and the transmission shaft 16 drives the second bevel gear 19 to rotate through the first bevel gear 18, and the second bevel gear 19 drives the lead screw 11 to rotate, thereby driving the opening and closing plate 10 to rise; when the pressing plate 4 is located at the connection between the feed hopper 2 and the arc-shaped transition plate 3, the second gear 17 is separated from the rack 15, and the opening and closing plate 10 is fully extended to close the passage between the feed hopper 2 and the storage hopper 9; the rope winder 8 continues to release the connecting rope 27, and the pressing plate 4 continues to slide down into the feed hopper 2, pressing down the construction waste until the pressing plate 4 moves to the bottom of the chute 6.

[0050] When the construction waste in the feed hopper 2 is crushed, the rope winder 8 is reversed to retract the connecting rope 27, and the connecting rope 27 drives the pressure plate 4 to slide upward; when the pressure plate 4 moves upward to the bottom of the arc-shaped transition plate 3, the rack 15 engages with the second gear 17, thereby rotating the lead screw 11 in the opposite direction and lowering the opening and closing plate 10; when the pressure plate 4 moves upward to the top of the arc-shaped transition plate 3, the opening and closing plate 10 completely opens the passage between the feed hopper 2 and the storage hopper 9, and the construction waste in the storage hopper 9 slides into the feed hopper 2; thereby, automatic intermittent replenishment of the construction waste in the feed hopper 2 is realized while continuous feeding is being carried out, thereby improving work efficiency, and the operation is simple and convenient. At the same time, during the continuous feeding process, it will not affect the pressure of the pressure plate 4 on the construction waste.

[0051] Reference Figure 1 The height from the bottom of the storage hopper 9 close to the end of the feed hopper 2 to the ground is smaller than the height from the bottom of the storage hopper 9 away from the end of the feed hopper 2 to the ground, so that the bottom of the storage hopper 9 is inclined to facilitate the sliding of construction waste into the feed hopper 2. A plurality of rollers 20 are rotatably connected to the bottom of the storage hopper 9 for assisting the construction waste to enter the feed hopper 2, so as to reduce the situation where the construction waste stays in the storage hopper 9.

[0052] The implementation principle of a construction waste recycling device in an embodiment of the present application is as follows: the construction waste is continuously transported to the storage hopper 9, the opening and closing plate 10 opens the channel between the storage hopper 9 and the feed hopper 2, and the construction waste enters the feed hopper 2; the rope winding machine 8 is started, the pressure plate 4 is moved downward along the arc-shaped transition plate 3, and the opening and closing plate 10 is driven to close the channel between the storage hopper 9 and the feed hopper 2. The pressure plate 4 is moved into the feed hopper 2 under the guidance of the arc-shaped transition plate 3 to abut against the construction waste, so that the cylindrical or relatively smooth construction waste is in close contact with the crushing mechanism, thereby reducing the flipping and rolling of the construction waste in the group in the feed hopper 2, so as to facilitate the crushing of the construction waste; when the construction waste in the feed hopper 2 is crushed, the rope winding machine 8 is rotated in the opposite direction to pull up the pressure plate 4, and the opening and closing plate 10 is lowered at the same time, and the opening and closing plate 10 completely opens the channel between the storage hopper 9 and the feed hopper 2, and the construction waste stored in the storage hopper 9 is released into the feed hopper 2.

When the pressing plate 4 moves to the connection between the feed hopper 2 and the arc-shaped transition plate 3, the opening and closing plate 10 closes the passage between the feed hopper 2 and the storage hopper 9, and continues to move downward to abut against the construction waste;

[0056] S3: When the construction waste in the feed hopper 2 is crushed, the rope winder 8 is rotated in the opposite direction, and the rope winder 8 pulls up the pressure plate 4. When the pressure plate 4 moves to the arc-shaped transition plate 3, the rack 15 engages with the second gear 17, and the opening and closing plate 10 is lowered. The rope winder 8 continues to be rotated until the pressure plate 4 moves to the top of the arc-shaped transition plate 3. At this time, the opening and closing plate 10 completely opens the passage between the storage hopper 9 and the feed hopper 2, and releases the construction waste stored in the storage hopper 9 into the feed hopper 2.
