Through waste transportation technology, the device can efficiently collect the crushed materials of civil engineering and construction waste, and transport these crushed materials to the designated recycling location for convenient storage and placement.

[0003] In the existing public documents, the patent announcement number CN215694607U discloses a civil engineering construction waste collection device. This technology crushes the civil engineering waste through a crushing box and guides it to the ground through a guide plate for re-accumulation and centralized treatment. During the guide plate's guide process, the iron products in the waste are collected through a recycling component set above it. This solves the problem of how to obtain iron products such as steel bars from some large concretes mixed with iron products such as steel bars, so as to utilize the waste. However, this technology still has the following defects:

[0004] During the crushing and recycling process of civil engineering and construction waste, a transportation device is needed to discharge the crushed civil engineering waste downward. When the crushed civil engineering waste is discharged to the bottom, the bottom will be continuously accumulated with the crushed civil engineering waste, which will cause blockage problems of the crushed civil engineering waste, and even cause the crushed civil engineering waste to overflow and spread everywhere. It is difficult to know the transportation and accumulation status of the crushed civil engineering waste in time, and it is difficult to realize efficient transportation of the crushed civil engineering waste that exceeds the limit in time. Therefore, a civil engineering waste crushing and recycling device is provided. Summary of the invention

[0008] When this technology is in use, the reduction motor drives the screw to rotate, and the screw drives the socket block to move left under the action of the thread transmission force, the socket block drives the transport box to move left, and the frame plate drives the moving wheel to move left and roll. When the distance value sensed by the moving distance sensor to the socket block is the same as the positioning distance value set by the controller, the controller is used to control the reduction motor. In this way, when the transport box is located at the designated transport discharge position, the push block is pushed to the right by the push electric cylinder, and the discharge plate is moved to the right and opened on the transport box, and the crushed civil engineering and construction waste inside the transport box is transported and discharged. The push electric cylinder pushes the push bar, and the linkage bar drives the push plate to move backward. The push plate can transport and push out the crushed civil engineering and construction waste inside the transport box, and avoid the accumulation of a large amount of crushed civil engineering and construction waste at the bottom of the transport channel that cannot be handled in time.

[0009] Preferably, the positioning and separating material transport mechanism comprises a downward pressure electric cylinder fixedly arranged on one side of the support plate; the output end of the downward pressure electric cylinder is fixedly connected to a pressure block, one side of the pressure block is fixedly installed with a downward pressure distance sensor, the outer wall of the pressure block and the side adjacent to the downward pressure distance sensor are fixedly connected with a spacing baffle, and the spacing baffle is slidably connected to the transport channel;

[0010] The bottom end of the spacer baffle is fixedly connected with a sharp bar. The outer wall of the spacer baffle and the inner wall of the transport channel are both smooth surfaces, and the spacer baffle and the sharp bar are both made of stainless steel.

[0011] When this technology is in use, the downward pressure electric cylinder pushes the pressing block to move downward and tilted, and at the same time, the downward pressure distance sensor is moved toward the inclined surface of the transport channel to achieve approach operation, and the spacing baffle moves downward along the inner wall of the transport channel, and the pointed bars can cut off and block the crushed civil engineering and construction waste inside the transport channel.

[0012] Preferably, the transport state processing component includes a guide frame fixedly arranged at the output end of the displacement motor; the inner wall of the guide frame is slidably connected with a displacement column, and both sides of the guide frame are slidably connected with limit rings, and the two limit rings are fixedly connected to the displacement column, and the two ends of the displacement column are fixedly connected with linkage groove columns; the outer wall of each linkage groove column is slidably connected with a sleeve slider, and the bottom end of the transport channel is fixedly connected with two limit baffles, and the limit baffles are slidably connected to the linkage groove column; an infrared distance sensor is fixedly installed inside the linkage groove column, and the two limit rings are symmetrically arranged with respect to the guide frame, and the outer wall of the displacement column and the inner wall of the guide frame are both smooth surfaces, and the two sleeve sliders are symmetrically arranged with respect to the transport channel, and the sleeve slider is fixedly connected to the transport channel.

[0013] When this technology is in use, the displacement motor drives the guide frame to rotate counterclockwise by sixty degrees, while the displacement column slides on the inner wall of the guide frame, the two limit rings slide along the outer wall of the guide frame, the linkage slot column slides rightward along the inner wall of the sleeve slider, and the linkage slot column drives the infrared distance sensor to detect the rightward movement above the transport box, so that the infrared distance sensor can sense the stacking height of the crushed civil engineering and construction waste inside the transport box. The displacement motor drives the guide frame to rotate clockwise by sixty degrees, the displacement column drives the two limit rings to move left, the displacement column drives the two linkage slot columns to move left synchronously, and the linkage slot column drives the infrared distance sensor to move left. As the displacement motor continuously rotates counterclockwise by sixty degrees and then clockwise by sixty degrees, the two infrared distance sensors can be reciprocated along the top of the transport box.

[0014] Technical effects and advantages of the present invention:

[0015] 1. The present invention uses a positioning synchronous transportation mechanism. When the crushed civil engineering and construction waste inside the transportation box exceeds the limit, the reduction motor drives the screw to rotate, and the socket block drives the transportation box to move left. When the distance value sensed by the moving distance sensor to the socket block is the same as the positioning distance value set by the controller, the controller uses the reduction motor to quickly position the transportation box at the designated transportation and discharge position, and the pushing electric cylinder pushes the pushing block to move right, and the discharge plate moves right and opens on the transportation box, so that the crushed civil engineering and construction waste inside the transportation box can be transported and discharged. The pushing electric cylinder pushes the pushing bar, and the pushing bar drives the linkage bar to move backward, and the pushing plate is pushed backward along the inner wall of the transportation box, so that the transportation and pushing operation of the crushed civil engineering and construction waste inside the transportation box can be realized, and the transportation and stacking situation of the crushed civil engineering and construction waste can be known in time. For the super-high stacked crushed civil engineering and construction waste, efficient transportation can be realized in time.

[0016] 2. The present invention adopts a positioning and spacing material transportation mechanism. When the height value sensed by the infrared distance sensor is the same as the over-limit height value set by the controller, the downward pressure electric cylinder pushes the pressure block to move downward, and the downward pressure distance sensor realizes a close operation to the inclined surface on the transport channel. The spacing baffle moves downward along the inner wall of the transport channel, and the spacing baffle drives the pointed bar to move downward. The spacing baffle blocks the crushed civil engineering and construction waste inside the transport channel, and quickly transports the super-high piled crushed civil engineering and construction waste in a timely and efficient manner.

[0017] 3. The present invention uses a transport state processing component. The position shifting motor drives the guide frame to rotate sixty degrees counterclockwise, and the guide frame drives the limit ring to move to the right. The two limit rings slide along the outer wall of the guide frame, and the linkage slot column slides to the right along the inner wall of the sleeve slider. The position shifting motor drives the guide frame to rotate sixty degrees clockwise, and the position shifting column drives the two limit rings to move left, and the position shifting column drives the two linkage slot columns to move left synchronously. As the position shifting motor continuously rotates sixty degrees counterclockwise and then sixty degrees clockwise, the two infrared distance sensors can be reciprocated along the top of the transport box, thereby realizing bilateral synchronous stacking height sensing of the crushed civil engineering and construction waste, so that the transportation stacking status can be known in time, and the super-high stacked crushed civil engineering and construction waste can be quickly and efficiently transported in time.

[0018] The interaction of the above multiple effects first enables the two infrared distance sensors to synchronously sense the stacking height of the crushed civil engineering and construction waste, and then enables the spacing baffle to drive the pointed bar to tilt downward, and the spacing baffle blocks the crushed civil engineering and construction waste inside the transport channel. Finally, the transport box is quickly located at the designated transport discharge position, the discharge plate moves right on the transport box and opens, and the push plate pushes backward along the inner wall of the transport box. In summary, the transportation and stacking status of the crushed civil engineering and construction waste can be known in a timely manner, and for the super-high stacked crushed civil engineering and construction waste, efficient transportation can be achieved in a timely manner.

[0039] The implementation principle of the civil engineering and construction waste crushing and recycling device of the present invention is as follows:

[0040] Step 1: When transporting and recycling civil engineering and construction waste, the expansion bolts are inserted into the holes of the mounting plate 17 to fix the mounting plate 17 on the ground base, so that the mounting plate 17 supports the transport channel 1 and increases the stability of the transport channel 1. The civil engineering and construction waste is transported to the inside of the recycling box 19, and the driving motor 21 is started by the controller 18. The driving motor 21 drives the crushing roller 20 to rotate, and the crushing roller 20 drives the gear 22 to rotate. The two gears 22 are meshed with each other, so that the two gears 22 crush the civil engineering and construction waste and discharge it into the inside of the transport channel 1, and then discharge it into the transport box 8 through the transport channel 1. At the same time, the two limit baffles 34 limit the crushed civil engineering and construction waste and discharge it. The crushed civil engineering and construction waste is transported to the transport box 8, so that the crushed civil engineering and construction waste will continue to accumulate inside the transport box 8 and spread to the surrounding surface positions.

[0041] Step 2, during the transport state processing, the controller 18 is used to start the shifting motor 28, and the shifting motor 28 drives the guide frame 29 to rotate sixty degrees counterclockwise. The guide frame 29 drives the shifting column 30 to move right, and the shifting column 30 slides on the inner wall of the guide frame 29. At the same time, the shifting column 30 drives the two limit rings 31 to move right, and the two limit rings 31 slide along the outer wall of the guide frame 29. At the same time, the shifting column 30 drives the two linkage groove columns 32 to move right synchronously, and the linkage groove column 32 slides to the right along the inner wall of the sleeve slider 33. At the same time, the linkage groove column 32 slides to the right along the limit baffle 34, and the linkage groove column 32 drives the infrared distance sensor 35 to detect the right movement above the transport box 8, so that the infrared distance sensor 35 can sense the stacking height of the crushed civil engineering and construction waste inside the transport box 8.

[0042] Then, the guide frame 29 is driven by the position-shifting motor 28 to rotate sixty degrees clockwise, the guide frame 29 drives the position-shifting column 30 to move leftward, the position-shifting column 30 drives the two limit rings 31 to move leftward, the position-shifting column 30 drives the two linkage slot columns 32 to move leftward synchronously, the linkage slot columns 32 slide leftward along the inner wall of the sleeve slide block 33, and the linkage slot columns 32 drive the infrared distance sensor 35 to move leftward, as the position-shifting motor 28 continuously rotates sixty degrees counterclockwise and then sixty degrees clockwise, the two infrared distance sensors 35 can be reciprocated along the top of the transport box 8, thereby realizing the stacking height sensing of the crushed civil engineering and construction waste. When the height value sensed by the infrared distance sensor 35 is the same as the over-limit height value set by the controller 18, the controller 18 immediately starts the downward pressure electric cylinder 23.

[0043] Step three, during the positioning and separation of materials for transportation, the downward pressure electric cylinder 23 pushes the pressing block 24 to move tilted downward, and the pressing block 24 drives the downward pressure distance sensor 25 to move tilted downward, and at the same time, the downward pressure distance sensor 25 approaches the inclined surface of the transport channel 1, and at the same time, the pressing block 24 drives the spacing baffle 26 to move tilted downward, and the spacing baffle 26 moves tilted downward along the inner wall of the transport channel 1, and the spacing baffle 26 drives the pointed bar 27 to move tilted downward, and the pointed bar 27 can cut off and block the crushed civil engineering and construction waste inside the transport channel 1, and at the same time, the spacing baffle 26 blocks the crushed civil engineering and construction waste inside the transport channel 1.

[0044] Step 4, during positioning and synchronous transportation, the reduction motor 5 is started simultaneously through the controller 18, the reduction motor 5 drives the screw 4 to rotate, the screw 4 rotates forward inside the slide frame 3, and the screw 4 drives the socket block 7 to move left under the action of the thread transmission force. At the same time, the transport channel 1 provides a supporting force to the support plate 2, and the support plate 2 provides a supporting force to the slide frame 3. In this way, the socket block 7 drives the transport box 8 to move left, the transport box 8 drives the two frame plates 9 to move left, and the frame plates 9 drive the moving wheel 36 to move left and roll. At the same time, the moving distance sensor 6 realizes distance sensing for the socket block 7. When the distance value sensed by the moving distance sensor 6 to the socket block 7 is the same as the positioning distance value set by the controller 18, the controller 18 is used for the reduction motor 5.

[0045] In this way, the transport box 8 is located at the designated transport and discharge position, and the push block 11 is pushed to the right by pushing the electric cylinder 10, and the push block 11 drives the discharge plate 12 to move to the right, and the discharge plate 12 moves to the right and opens on the transport box 8, so that the crushed civil engineering and construction waste inside the transport box 8 can be transported and discharged. At the same time, the controller 18 starts the pushing electric cylinder 13, and the pushing electric cylinder 13 pushes the pushing bar 14, and the pushing bar 14 drives the linkage bar 15 to move backward, and the linkage bar 15 drives the pushing plate 16 to move backward, and the pushing plate 16 is pushed backward along the inner wall of the transport box 8, and the pushing plate 16 can realize the transport and pushing operation of the crushed civil engineering and construction waste inside the transport box 8, so that the bottom of the transport channel 1 can avoid the accumulation of a large amount of crushed civil engineering and construction waste that cannot be handled in time, and the accumulation state of the crushed civil engineering and construction waste can be known in time, and the crushed civil engineering and construction waste can be handled in time.
