[0014] In a second aspect of the invention, a method of using a civil engineering construction waste treatment device is also provided, comprising: S1. The inside of the cleaning tank is filled with cleaning water. The building stones to be processed are added to the feed end of the first cylinder. The cover plate is rotated by the output end of the motor to close the feed end of the first cylinder. Under the action of the output end of the water pump, the cleaning water in the cleaning tank is pumped into the first cylinder. S2. The first drive motor on the first cylinder drives the conveying screw to rotate, which turns and cleans the cleaning water and building stones in the first cylinder. On the other hand, the conveying screw also conveys the building stones. By controlling the forward and reverse rotation of the conveying screw, the building stones move left and right. The building stones will not move to the outlet position during the cleaning process. S3. After cleaning, the conveying screw conveys the building stones to the discharge end of the first cylinder. The cleaned water and concrete fall into the cleaning tank through the outlet. The barrier filter plate in the cleaning tank blocks the concrete, so the concrete will not enter the front of the barrier filter plate during the next cleaning, realizing the recycling of water resources and saving water resources. In addition, the barrier filter plate is detachable, which makes it easy for the staff to clean and replace the barrier filter plate, greatly improving its practicality. S4. After the building stones are located at the discharge end of the first cylinder, the outlet of the discharge end is opened by the opening and closing mechanism on the first cylinder, so that the building stones fall into the second cylinder. The inner wall of the second cylinder is equipped with a heating element. The output end of the first drive motor on the second cylinder drives the conveying screw to rotate, so that the building stones move back and forth. The heating element dries the cleaned building stones. Since the feed end of the second cylinder is open, the gas evaporated by water during heating is scattered out, avoiding safety accidents caused by excessive pressure. S5. When cleaning the concrete in the cleaning tank, the water pump draws the water in the cleaning tank into the first cylinder for storage. Then, the heating plate at the bottom of the cleaning tank is activated to dry the concrete. The output end of the cylinder drives the baffle to move upward, opening the soil outlet at the back of the cleaning tank. The output end of the hydraulic rod drives the cleaning blade to move downward, making it fit against the heating plate at the bottom of the cleaning tank. The output end of the first stepper motor drives the first lead screw to rotate, causing the cleaning blade to move backward, cleaning the dried concrete out of the soil outlet and letting it fall into the collection box. S6. The dried building stones are conveyed to the discharge end of the second cylinder by the rotation of the conveying screw. The outlet of the discharge end is opened by the opening and closing mechanism on the second cylinder, allowing the building stones to fall into the crushing box. The two sets of crushing rollers at the top of the crushing box crush the building stones. During the crushing process, the output end of the second stepper motor drives the second screw to rotate, causing the lifting plate to move downward, which in turn drives the pressure plate to move downward, squeezing the connecting plate and causing the fastening spring to be in a contracted state. Then, the output end of the second drive motor drives the pressure plate to rotate, and the pressure plate is no longer located on the top of the connecting plate, releasing the squeezing of the connecting plate. Under the action of the fastening spring restoring its deformation, the crushing box moves up and down, realizing vibration. The crushed stones that meet the particle size requirements pass through the screening plate and enter the collection box for collection, while the larger particles remain on the top of the screening plate. S7. Since the collection box and lifting block are detachably connected, and the crushing box and screening plate are also detachably connected, it is convenient for the staff to remove the screening plate and collection box to collect crushed stone that meets the particle size requirements as well as crushed stone with larger particle size. The whole process is automated and meets the needs of the staff.

[0015] Compared with the prior art, the present invention provides a civil engineering construction waste treatment device, which has the following beneficial effects: This invention features a first cylinder, a second cylinder, and a crushing box working together to clean building stones, remove concrete from their surfaces, and then dry and crush the cleaned stones. The entire process is automated, convenient, and fast. Additionally, a cleaning mechanism and a heating plate work together to dry and remove any concrete falling into the cleaning box. Furthermore, a drive mechanism and a lifting mechanism work together to vibrate the crushed stones, improving the screening effect. Both the collection box and the screening plate are detachable, allowing workers to easily collect stones that meet the particle size requirements, as well as larger stones, thus satisfying their needs.

[0031] Those skilled in the art will understand that by driving the third lead screw 502 to rotate through the output end of the third stepper motor 504, the lifting block 505 moves up and down along the surface of the third guide rod 503, thereby driving the collection box 120 to move up and down.

[0032] To clearly describe the working principle of this invention, we will use... Figure 1 The explanation is based on a directional perspective, as follows: S1. The cleaning tank 101 is filled with cleaning water. Building stones to be processed are added to the feed end of the first cylinder 102. The cover plate 107 is rotated by the output end of the motor 106 to close the feed end of the first cylinder 102. Under the action of the output end of the water pump 104, the cleaning water in the cleaning tank 101 is pumped into the first cylinder 102. S2. The first drive motor 108 on the first cylinder 102 drives the conveying screw to rotate, which turns and cleans the cleaning water and building stones in the first cylinder 102. On the other hand, the conveying screw also serves to convey the building stones. By controlling the forward and reverse rotation of the conveying screw, the building stones can move left and right. The building stones will not move to the water outlet position during the cleaning process. S3. After cleaning, the conveying screw conveys the building stones to the discharge end of the first cylinder 102. The cleaned water and concrete fall into the cleaning tank 101 through the outlet. The barrier filter plate 103 in the cleaning tank 101 blocks the concrete. Therefore, during the next cleaning, the concrete will not enter the front of the barrier filter plate 103, realizing the recycling of water resources and saving water resources. In addition, the barrier filter plate 103 is detachable, which makes it easy for the staff to clean and replace the barrier filter plate 103, greatly improving its practicality. S4. After the building stones are located at the discharge end of the first cylinder 102, the outlet of the discharge end is opened by the opening and closing mechanism 3 on the first cylinder 102, so that the building stones fall into the second cylinder 113. The inner wall of the second cylinder 113 is equipped with a heating element. The output end of the first drive motor 108 on the second cylinder 113 drives the conveying screw to rotate, so that the building stones move back and forth. The heating element dries the cleaned building stones. Since the feed end of the second cylinder 113 is open, the gas evaporated by water during heating is scattered out, avoiding safety accidents caused by excessive pressure. S5. When cleaning the concrete in the cleaning tank 101, the water pump 104 pumps the water in the cleaning tank 101 into the first cylinder 102 for storage. Then, the heating plate 112 at the bottom of the cleaning tank 101 is activated to dry the concrete. Then, the output end of the cylinder 109 drives the baffle 110 to move upward, opening the soil outlet on the back of the cleaning tank 101. The output end of the hydraulic rod 205 drives the cleaning blade 206 to move downward, fitting against the heating plate 112 at the bottom of the cleaning tank 101. The output end of the first stepper motor 203 drives the first lead screw 201 to rotate, causing the cleaning blade 206 to move backward, cleaning the dried concrete out of the soil outlet and falling into the collection frame 111. S6. The dried building stones are conveyed to the discharge end of the second cylinder 113 by the rotation of the conveying screw. The outlet of the discharge end is opened by the opening and closing mechanism 3 on the second cylinder 113, allowing the building stones to fall into the crushing box 114. The two sets of crushing rollers 115 at the top of the crushing box 114 crush the building stones. During the crushing process, the output end of the second stepper motor 404 drives the second lead screw 402 to rotate, causing the lifting plate 405 to move downward, which in turn drives the pressure plate 407 to move downward, thus connecting the... The plate 117 is squeezed, causing the fastening spring 119 to be in a contracted state. Then, the output end of the second drive motor 406 drives the pressure plate 407 to rotate. The pressure plate 407 is no longer located on top of the connecting plate 117, releasing the squeeze on the connecting plate 117. Under the action of the fastening spring 119 restoring its deformation, the crushing box 114 moves up and down to achieve vibration. After crushing, the crushed stone that meets the particle size requirements enters the collection box 120 through the screening plate 116 for collection, while the larger particles remain on top of the screening plate 116. S7. Since the collection box 120 and the lifting block 505 are detachably connected, and the crushing box 114 and the screening plate 116 are also detachably connected, it is convenient for the staff to remove the screening plate 116 and the collection box 120 to collect crushed stone that meets the particle size requirements and crushed stone with larger particle size. The whole process is automated and meets the needs of the staff.

10. A method of using a civil engineering construction waste treatment device, for implementing the civil engineering construction waste treatment device as described in any one of claims 1-9, characterized in that, include: S1. The cleaning tank (101) is filled with cleaning water. Building stones to be processed are added to the feed end of the first cylinder (102). The cover plate (107) is rotated by the output end of the motor (106) to close the feed end of the first cylinder (102). Under the action of the output end of the water pump (104), the cleaning water in the cleaning tank (101) is pumped into the first cylinder (102). S2. The first drive motor (108) on the first cylinder (102) drives the conveying screw to rotate, which turns and cleans the cleaning water and building stones in the first cylinder (102). On the other hand, the conveying screw also serves to convey the building stones. By controlling the forward and reverse rotation of the conveying screw, the building stones move left and right. The building stones will not move to the water outlet position during the cleaning process. S3. After cleaning, the conveying screw conveys the building stones to the discharge end of the first cylinder (102). The cleaned water and concrete fall into the cleaning tank (101) through the water outlet. The barrier filter plate (103) in the cleaning tank (101) blocks the concrete. Therefore, during the next cleaning, the concrete will not enter the front side of the barrier filter plate (103), realizing the recycling of water resources and saving water resources. In addition, the barrier filter plate (103) is detachable, which makes it easy for staff to clean and replace the barrier filter plate (103), greatly improving its practicality. S4. After the building stones are located at the discharge end of the first cylinder (102), the outlet of the discharge end is opened by the opening and closing mechanism (3) on the first cylinder (102), so that the building stones fall into the second cylinder (113). The inner wall of the second cylinder (113) is equipped with a heating element. The output end of the first drive motor (108) on the second cylinder (113) drives the conveying screw to rotate, so that the building stones move back and forth. The heating element dries the cleaned building stones. Since the feed end of the second cylinder (113) is open, the gas evaporated by the water during heating is scattered out, avoiding safety accidents caused by excessive pressure. S5. When cleaning the concrete in the cleaning box (101), the water pump (104) pumps the water in the cleaning box (101) into the first cylinder (102) for storage. Then, the heating plate (112) at the bottom of the cleaning box (101) is activated to dry the concrete. Then, the output end of the cylinder (109) drives the baffle (110) to move upward, opening the soil outlet on the back of the cleaning box (101). The output end of the hydraulic rod (205) drives the cleaning blade (206) to move downward, fitting against the heating plate (112) at the bottom of the cleaning box (101). The output end of the first stepper motor (203) drives the first screw (201) to rotate, causing the cleaning blade (206) to move backward, cleaning the dried concrete from the soil outlet and dropping it into the collection frame (111). S6. The dried building stones are conveyed to the discharge end of the second cylinder (113) by the rotation of the conveying screw. The outlet of the discharge end is opened by the opening and closing mechanism (3) on the second cylinder (113), so that the building stones fall into the crushing box (114). The two sets of crushing rollers (115) at the top of the crushing box (114) crush the building stones. During the crushing process, the output end of the second stepper motor (404) drives the second screw (402) to rotate, so that the lifting plate (405) moves downward, which drives the pressure plate (407) to move downward, and the connecting plate ( 117) is squeezed, so that the fastening spring (119) is in a contracted state. Then, the output end of the second drive motor (406) drives the pressure plate (407) to rotate. The pressure plate (407) is no longer located on the top of the connecting plate (117), releasing the squeeze on the connecting plate (117). Under the action of the fastening spring (119) restoring its deformation, the crushing box (114) moves up and down to achieve vibration. After crushing, the crushed stone that meets the particle size requirements enters the collection box (120) through the screening plate (116) for collection, while the larger particles remain on the top of the screening plate (116). S7. Since the collection box (120) and the lifting block (505) are detachably connected, the crushing box (114) and the screening plate (116) are also detachably connected, which makes it easy for the staff to remove the screening plate (116) and the collection box (120) to collect crushed stone that meets the particle size requirements and crushed stone with larger particle size. The whole process is automated and meets the needs of the staff.
