The connecting component 23 is mainly responsible for guiding and collecting the construction waste. The guide frame 231 fixedly connected to the top of the device body 1 can guide the input construction waste to smoothly enter the crushing component 21. The guide plates 232 fixedly connected to both sides of the inner wall of the device body 1 allow the crushed and screened construction waste to slide down a specific path, preventing it from scattering. The hinged cabinet door 233 hinged to the front of the second filter box 2214 is easy to open and is used to clean and collect the screened construction waste inside the second filter box 2214. The transfer box 234 fixedly connected to the bottom of the second filter box 2214 can temporarily store the screened construction waste, facilitating subsequent unified transfer and processing, thus improving the convenience and environmental friendliness of the entire recycling and screening process.

[0031] Furthermore, the inner wall of the transmission wheel 211 is fixedly connected to the outer wall of the rotating shaft 223, the meshing gears 215 mesh with each other and rotate inward, the transmission shaft 214 is rotatably connected to the inner wall of the device body 1; the guide plate 232 is fixedly connected to both sides of the inner wall of the device body 1.

[0032] Furthermore, the transmission shaft 214, which is fixedly connected to the inner wall of the transmission wheel 213, will also rotate. The crushing roller 216, which is fixedly connected to the outer wall of the middle section of the transmission shaft 214, will also operate. The meshing gears 215 on the two crushing rollers 216 will mesh with each other and rotate inward. When the construction waste enters the crushing area, under the squeezing and tearing action of the two crushing rollers 216, large pieces of construction waste will be crushed into smaller particles, preparing for subsequent screening. The connecting component 23 is mainly responsible for guiding and collecting the construction waste. The guide frame 231, which is fixedly connected to the top of the device body 1, can guide the input construction waste to smoothly enter the crushing component 21. The guide plates 232, which are fixedly connected to both sides of the inner wall of the device body 1, can make the crushed and screened construction waste slide down a specific path to avoid scattering.

[0033] Working principle: The crushing component 21 undertakes the important task of initially crushing large pieces of construction waste. The inner wall of the first transmission wheel 211 is fixedly connected to the outer wall of the rotating shaft 223. When the rotating shaft 223 rotates, the first transmission wheel 211 rotates accordingly. The first transmission wheel 211 is connected to the second transmission wheel 213 through the transmission belt 212, thereby driving the second transmission wheel 213 to rotate. The transmission shaft 214 fixedly connected to the inner wall of the second transmission wheel 213 will also rotate. The crushing roller 216 fixedly connected to the outer wall of the middle section of the transmission shaft 214 will also rotate. The meshing gears 215 on the two crushing rollers 216 mesh with each other and rotate inward. When the construction waste enters the crushing area, under the squeezing and tearing action of the two crushing rollers 216, the large pieces of construction waste are crushed into smaller particles, preparing for the subsequent screening work.

[0034] The screening component 22 is a key part for classifying construction waste by particle size. The fixing frame 221 is fixed to the outer wall of the device body 1, providing stable support for the drive motor 222. The output end of the drive motor 222 is fixedly connected to the rotating shaft 223. Starting the drive motor 222 drives the rotating shaft 223 to rotate. The circular blocks on both sides of the outer wall of the rotating shaft 223 act as limiters, and the return spring 224 is located inside the circular blocks. During the rotation of the rotating shaft 223, the sliding inclined block 225 slides along the middle section of the outer wall of the rotating shaft 223 under centrifugal force, thereby pushing the rotating ring 226 to reciprocate up and down. The fixing rod 227 and brush plate 228 fixedly connected to the top of the rotating ring 226 also move up and down accordingly. The brush plate 228 is slidably connected to the bottom of the first filter box 229, which can... The filter screen of the first filter box 229 is cleaned to prevent screen blockage and ensure smooth screening.

Smaller particles of construction waste after being screened by the first filter box 229 fall into the second filter box 2214 for further screening and classification.

[0035] The connecting component 23 is mainly responsible for guiding and collecting construction waste. The guide frame 231, which is fixedly connected to the top of the device body 1, guides the input construction waste smoothly into the crushing component 21. The guide plates 232, which are fixedly connected to both sides of the inner wall of the device body 1, allow the crushed and screened construction waste to slide down a specific path, preventing it from scattering. The hinged cabinet door 233, which is hinged to the front of the second filter box 2214, is easy to open and is used to clean and collect the screened construction waste inside the second filter box 2214. The transfer box 234, which is fixedly connected to the bottom of the second filter box 2214, can temporarily store the screened construction waste, facilitating subsequent unified transfer and processing, thus improving the convenience and environmental friendliness of the entire recycling and screening process.
