[0002] The pre-processable waste precast concrete component recycling crusher is mainly used to crush the waste precast concrete components for subsequent resource recovery and reuse. The waste precast concrete components are fed into the crushing chamber of the crusher, so that the high-speed rotating rotor or hammer head impacts and shears the waste materials, thereby achieving crushing. The crushed materials are further processed by the screening system to obtain aggregates or crushed materials that meet the requirements.

[0003] At present, most of the existing waste precast concrete component recycling crushers easily cause waste materials to accumulate in the crushing chamber during the crushing process, and cannot be sent between the crushing rollers for effective crushing in time.

[0015] The present invention provides a pre-processable waste concrete precast component recycling crusher, which has the following beneficial effects: (1) The pre-processable waste concrete precast component recycling crusher, when the device is in the process of crushing, through the transmission of the transmission wheel and other devices, the cam rotates, and in this process the cam squeezes the frame, causing the frame to move downward. At this time, the cross plate fixedly connected to the frame exerts a force on the hinge rod, causing the T-shaped rod to drive the round rod to slide in the cross groove.

[0016] (2) In the pre-processable waste concrete precast component recycling crusher, when the motor 2 is started, the rotating shaft at the output end of the motor 2 drives the convex block to rotate.

When the pressure of the convex block on the moving frame disappears, the moving frame returns to its original position under the elastic force of the spring 2. This design enables the moving frame to drive the screen frame to perform reciprocating motion through the cooperation between the convex block and the spring 2, thereby improving the screening efficiency of the screen.

[0017] (3) In the pre-processable waste concrete precast component recycling crusher, when the moving frame moves, the arc rod exerts a force on the roller, so that the sliding rod drives the screen frame to move up and down. When the roller passes the highest point of the arc rod, under the action of gravity, the roller moves downward along the arc rod. Through the cooperation between the roller and the arc rod, the screen frame reciprocates up and down while the moving frame reciprocates, thereby further improving the screening efficiency of the screen and ensuring that materials of different particle sizes in the waste can be effectively separated.

[0018] (4) In the pre-processable waste concrete precast component recycling crusher, when the screen frame moves upward, the screen frame will exert a force on the connecting rod, causing the slider to slide in the slide groove. When the slider moves, the impact rod fixedly connected to the slider moves synchronously, causing the impact rod to hit the outer wall of the screen frame, causing the screen frame to vibrate. At the same time, the vibration of the screen further improves the screening efficiency of the screen, further ensuring that materials of different particle sizes in the waste can be effectively separated.

The shaft of the driven wheel 2 473 penetrates the shell 1 and is rotatably connected to the shell 1. The shaft of the driven wheel 2 473 penetrates the cam 474 and is fixedly connected to the cam 474. The device utilizes the rotation of the cam 474 to drive the push plate 151 to reciprocate, and continuously pushes the waste to the crushing roller 1 47 and the crushing roller 2 48, which effectively solves the problem of waste accumulation during the crushing process, so that the waste can enter the crushing area more evenly, thereby significantly improving the crushing efficiency; Further, the outer wall of the shell 1 is fixedly connected with the motor 2 51, and the output end of the motor 2 51 is fixedly connected with the rotating shaft 52, the rotating shaft 52 penetrates the shell 1 and is rotatably connected with the shell 1, and the rotating shaft 52 penetrates the protrusion 53 and is fixedly connected with the protrusion 53. A moving frame 54 is provided inside the shell 1, and the outer walls at both ends of the moving frame 54 are respectively fixedly connected with the support rod 1 542 and the support rod 2 549, which penetrate the shell 1 and are slidably connected with the shell 1. The moving frame 54 is elastically connected to the inner wall of the shell 1 through the spring 2 543, and the moving frame 54 is provided with a through slot 541; Further, a screen frame 55 is provided in the moving frame 54, and a sliding plate 551 is fixedly connected to the side wall of the screen frame 55, and the sliding plate 551 is slidably connected to the through groove 541, and a sliding rod 552 is fixedly connected to the outer wall of the sliding plate 551, and the sliding rod 552 penetrates the moving frame 54 and is slidably connected to the moving frame 54, and a roller 553 is rotatably connected to the bottom of the sliding rod 552, and an arc rod 16 is provided below the roller 553, and the arc rod 16 is fixedly connected to the inner wall of the shell 1, and a support plate 544 is fixedly connected to the inner wall of the moving frame 54, and a slide groove 545 is provided on the support plate 544, and a slider 546 is slidably connected to the slide groove 545, and a connecting rod 547 is hinged at one end of the slider 546, and a striking rod 548 is fixedly connected to the other end of the slider 546, and the end of the connecting rod 547 away from the slider 546 is hinged to the outer wall of the screen frame 55, and the striking rod 548 penetrates the supporting plate 544 and is slidably connected to the supporting plate 544; like Figure 8 As shown, when the screen frame 55 moves upward, the screen frame 55 will exert a force on the connecting rod 547, causing the screen frame 55 to move upward. At the same time, during the upward movement of the screen frame 55, through the linkage mechanism of the connecting rod 547, the slider 546 and the impact rod 548, the impact rod 548 can hit the outer wall of the screen frame 55, causing the screen frame 55 to drive the screen 554 to vibrate, thereby preventing the screen holes from being blocked, maintaining the permeability of the screen, and thereby improving the continuous screening ability and efficiency of the equipment.

[0032] like Figure 7 As shown, when the moving frame 54 moves, the roller 553 will roll on the arc surface of the arc rod 16. During this process, the sliding rod 552 will drive the screen frame 55 to move upward first. When it reaches the highest point on the arc surface of the arc rod 16, the sliding rod 552 will drive the screen frame 55 to move downward. At this time, through the design of the arc rod 16 and the roller 553, the moving frame 54 drives the screen 554 to reciprocate up and down, thereby improving the screening efficiency of the screen 554.

[0033] Furthermore, a hydraulic cylinder 555 is fixedly connected to the outer wall of the screen frame 55, and an output end of the hydraulic cylinder 555 passes through the screen frame 55 and is slidably connected to the screen frame 55. A pull rod 556 is fixedly connected to the output end of the hydraulic cylinder 555, and a screen 554 is hinged at one end of the pull rod 556 away from the hydraulic cylinder 555. One end of the screen 554 away from the pull rod 556 is rotatably connected to the inner wall of the screen frame 55. The pull rod 556 is controlled by the hydraulic cylinder 555 to realize the flipping of the screen 554, and the outlet is opened to allow the waste on the screen 554 to automatically fall into the collection box 3, which simplifies the collection process, reduces manual operations, and improves the overall work efficiency and convenience.

[0034] In the present invention, when in use, firstly, the waste is poured into the shell 1 through the feed hopper 2, and then the motor 41 is started. When the motor 41 is started, the rotating shaft 42 fixed to the output shaft of the motor 41 drives the transmission wheel 43 and the transmission gear 49 to rotate synchronously. In this process, the driven gear 46 meshing with the transmission gear 49 rotates synchronously. When the transmission wheel 43 rotates, the driven wheel 45 rotates synchronously through the transmission of the transmission belt 44. At the same time, the crushing roller 47 and the crushing roller 2 48 rotate synchronously in the opposite direction through the transmission of the driven gear 46 and the driven wheel 45, so as to crush the waste. When the crushing roller 1 47 rotates, the transmission wheel 2 471 fixedly connected to the crushing roller 1 47 rotates synchronously. When the transmission wheel 2 471 rotates, the driven wheel 2 473 rotates synchronously through the transmission of the transmission belt 2 472. At the same time, the cam 474 fixedly connected to the shaft of the driven wheel 2 473 rotates. When the cam 474 rotates, the cam 474 squeezes the frame 157, so that the frame 157 moves downward, and the spring 159 is elastically deformed. When the frame 157 moves downward, the horizontal plate 156 fixedly connected to the frame 157 applies a force to the hinge rod 155, so that the T-bar 154 drives the round rod 153 to slide in the horizontal groove 12. During this process, the cross bar 152 exerts a force on the push plate 151, causing the push plate 151 to move, thereby moving the waste toward the crushing roller 1 47 and the crushing roller 2 48. When the force of the cam 474 on the frame 157 disappears, the frame 157 returns to its original position under the action of the spring 159. At the same time, the cross bar 152 drives the push plate 151 back to its original position through the transmission of the cross plate 156, the hinge rod 155 and the T-bar 154. This design allows the push plate 151 to reciprocate through the cooperation between the frame 157 and the spring 159, thereby causing the push plate 151 to continuously push the crushed materials toward the crushing roller 1 47 and the crushing roller 2 48, thereby improving the crushing efficiency of the device. During the waste crushing process, the second motor 51 is started, and the rotating shaft 52 at the output end of the second motor 51 drives the protrusion 53 to rotate. During this process, the protrusion 53 squeezes the moving frame 54, causing the moving frame 54 to move, and the second spring 543 is elastically deformed. When the pressure of the protrusion 53 on the moving frame 54 disappears, the moving frame 54 returns to its original position under the elastic force of the second spring 543. This design allows the moving frame 54 to drive the screen frame 55 to reciprocate through the cooperation between the protrusion 53 and the second spring 543, thereby improving the screening efficiency of the screen 554. When the moving frame 54 moves, the arc rod 16 exerts a force on the roller 553, so that the sliding rod 552 drives the screen frame 55 to move up and down. When the roller 553 passes the highest point of the arc rod 16, under the action of gravity, the roller 553 moves downward along the arc rod 16. Through the cooperation between the roller 553 and the arc rod 16, the screen frame 55 reciprocates up and down at the same time during the reciprocating motion of the moving frame 54, thereby further improving the screening efficiency of the screen 554. When the screen frame 55 moves upward, the screen frame 55 applies a force to the connecting rod 547, so that the slider 546 slides in the slide groove 545. When the slider 546 moves, the impact rod 548 fixedly connected to the slider 546 moves synchronously, so that the impact rod 548 hits the outer wall of the screen frame 55, so that the screen frame 55 drives the screen 554 to vibrate, and at the same time, the screen 554 vibrates, thereby further improving the screening efficiency of the screen 554. When the device has finished screening, the collection box 3 is pulled out to take out the collected waste, and then the collection box 3 is installed back into the shell 1, and then the hydraulic cylinder 555 is started to make the pull rod 556 rotate downward on the screen 554 along the hinge point with the screen frame 55, thereby opening an outlet, so that the waste on the screen 554 enters the collection box 3 along the screen 554, and finally the collection box 3 is pulled out again to complete the collection.
