[0025] The bracket 21 is fixedly connected to the side of the body 1, and the top surface of the bracket 21 is fixedly connected with a motor 22. The output shaft of the motor 22 penetrates the crushing roller 6 and is fixedly connected. The surface of the body 1 penetrates and is rotatably connected with a rotating rod 25. The rotating rod 25 and the output shaft of the motor 22 are penetrated and fixedly connected with a transmission wheel 23, and the transmission wheel 23 of the output shaft of the motor 22 and the transmission wheel 23 penetrated by the rotating rod 25 are transmission-connected through a transmission belt 24. The limiting groove 217 is provided on the inner side of the body 1, and the inner wall of the body 1 is slidingly connected with the screen 1 26 and the screen 2 27. When the raw materials of the recycled concrete are crushed, the raw materials of the recycled concrete are poured into the crushing box 5, and the motor 22 is started. The output shaft of the motor 22 will drive the crushing roller 6 to rotate, thereby making the crushing roller 6 The raw materials of the recycled concrete are crushed, and the crushed raw materials will enter the body 1 and fall onto the screen 1 26. The top surface of the screen 1 26 is fixedly connected with a stopper 28, and the side surface of the screen 1 26 is fixedly connected with a slider 216. The slider 216 passes through the limiting groove 217 and is slidably connected. The bottom surface of the screen 1 26 is fixedly connected with a protrusion 29, and a spring 218 is fixedly connected between the slider 216 and the inner side of the limiting groove 217. The rotation of the cam 214 will conflict with the protrusion 29, thereby forcing the protrusion 29 to drive the screen 1 26 and the slider 216 to move upward along the limiting groove 217, and the spring 218 will be compressed. After the cam 214 does not conflict with the protrusion 29, the spring 218 will push back the slider 216 to make the screen 1 26 shake up and down. The top surface of the second screen 27 is fixedly connected with a connecting rod 210, and the connecting rod 210 is penetrated by a support rod 211 and is slidably connected. The end of the support rod 211 close to the inner wall of the body 1 is fixedly connected to the inner wall of the body 1. The side of the connecting rod 210 close to the inner wall of the body 1 is fixedly connected with a spring 1 212, and the end of the spring 1 212 away from the connecting rod 210 is fixedly connected to the inner wall of the body 1. When the cam 214 rotates, it drives the toggle block 215 to push the toggle plate 213, so that the second screen 27 drives the connecting rod 210 to slide along the support rod 211, and compresses the spring 1 212, so that the second screen 27 is sieved left and right by the spring 1 212 to screen the raw materials of the recycled concrete again. The top surface of the screen mesh 27 is fixedly connected with a toggle plate 213, and one end of the rotating rod 25 located inside the machine body 1 penetrates and is fixedly connected with a cam 214. When the output shaft of the motor 22 rotates, the rotating rod 25 is driven to rotate together through the transmission wheel 23 and the transmission belt 24, and when the rotating rod 25 rotates, the cam 214 is driven to rotate together, and the surface of the cam 214 is fixedly connected with a toggle block 215. The control unit 3 includes a grid plate 31, which penetrates the machine body 1 and is slidably connected, and a movable groove 32 is opened on the inner side of the machine body 1.There are two groups of grid plates 31, and the two groups of grid plates 31 are symmetrically arranged up and down. The sides of the grid plates 31 are fixedly connected with inclined blocks 33. When the L-shaped push rod 34 moves upward, it will resist the inclined blocks 33, forcing the inclined blocks 33 to push the grid plates 31 to slide, so that the grids between the two groups of grid plates 31 are connected, so that the raw materials of the recycled concrete can enter the receiving box 7, and the inclined blocks 33 pass through the movable grooves 32 and are slidably connected. An L-shaped push rod 34 is passed through and slidably connected to the bottom end of the body 1. When the recycled concrete raw materials are crushed and collected, the collecting box 7 is pushed upward against the elastic hook 36, so that the edge of the collecting box 7 is against the elastic hook 36, and the elastic hook 36 hooks the edge of the collecting box 7, and at the same time, the collecting box 7 pushes the L-shaped push rod 34, causing the L-shaped push rod 34 to be pushed upward. The inner side of the L-shaped push rod 34 is fixedly connected to the bottom surface of the body 1, and a spring 35 is fixedly connected between the L-shaped push rod 34 and the body 1. The side of the body 1 is connected to the elastic hook 36, and the surface of the elastic hook 36 is fixedly connected to a pull rod 37.

[0026] Based on the above embodiment, when the raw materials of recycled concrete are crushed, the raw materials of recycled concrete are poured into the crushing box 5, and the motor 22 is started. The output shaft of the motor 22 drives the crushing roller 6 to rotate, so that the crushing roller 6 crushes the raw materials of recycled concrete, and the crushed raw materials enter the body 1 and fall onto the screen 1 26. When the output shaft of the motor 22 rotates, the rotating rod 25 is driven to rotate together through the transmission wheel 23 and the transmission belt 24. When the rotating rod 25 rotates, it drives the cam 214 to rotate together. The rotation of the cam 214 will abut the protrusion 29, thereby forcing the protrusion 29 to drive the screen 1 26 and the slider 216 along the limit groove 21 7 moves upward, and the spring 218 is compressed. After the cam 214 does not interfere with the protrusion 29, the spring 218 pushes back the slider 216 to make the screen 1 26 shake up and down, so that the raw materials of the recycled concrete that are crushed and qualified will fall on the screen 27. When the cam 214 rotates, it will drive the toggle block 215 to push the toggle plate 213, so that the screen 27 drives the connecting rod 210 to slide along the support rod 211, and compress the spring 1 212. The spring 1 212 makes the screen 27 sieve left and right to screen the raw materials of the recycled concrete again, ensuring that the raw materials of the recycled concrete can be used after being crushed, so that there is no need to screen and filter after collecting the materials, which is more convenient.

[0027] When the raw materials of the recycled concrete are crushed and then collected, the collecting box 7 is pushed upward against the elastic hook 36, so that the edge of the collecting box 7 is pushed against the elastic hook 36, so that the elastic hook 36 hooks the edge of the collecting box 7, and at the same time, the collecting box 7 pushes the L-shaped push rod 34, causing the L-shaped push rod 34 to be pushed upward, and the spring three 35 is compressed. When the L-shaped push rod 34 moves upward, it will resist the inclined surface block 33, forcing the inclined surface block 33 to push the grid plate 31 to slide, so that the grids between the two groups of grid plates 31 are connected, so that the raw materials of the recycled concrete can enter the collecting box 7. After the collection is completed, the pull rod 37 is pulled so that the elastic hook 36 no longer resists the collecting box 7. After the collecting box 7 is removed, the spring three 35 will pull back the L-shaped push rod 34, so that the grids between the grid plates 31 are staggered, thereby preventing excessive dust when the raw materials of the recycled concrete are crushed.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
