[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] Example 1, referring to Figures 1-4 and Figures 6-7 A waste crushing and recycling device for PE replacement pipe processing includes a servo conveyor 2 fixedly installed on the top outer wall of a support plate 1, a waste crushing mechanism, an intermittent feeding mechanism, a circulating feeding mechanism, and a receiving and recycling mechanism. The servo conveyor 2 has a left guide frame 28 and a right guide frame 29 fixed on its two sides in sequence. The front outer wall of the servo conveyor 2 is fixedly installed with a main control panel 35, which can automatically control all electrical components of the device. The waste crushing mechanism includes a discharge hopper 4 fixedly connected to the top outer wall of the servo conveyor 2 via a support frame 3, a crushing chamber 5 fixedly connected to the top outer wall of the discharge hopper 4, a feed hopper 6 fixedly connected to the top outer wall of the crushing chamber 5, a drive assembly, and two crushing rollers 7 rotatably installed inside the crushing chamber 5. Furthermore, the drive assembly includes a protective cover 8 fixedly connected to the front outer wall of the crushing chamber 5, a drive motor 9 fixedly installed on the front outer wall of the protective cover 8, a drive gear 10 fixedly mounted on the output shaft of the drive motor 9, and two transmission gears 11 sequentially fixedly mounted on the front ends of the two crushing rollers 7. The output shaft of the drive motor 9 passes through the front of the protective cover 8, the two transmission gears 11 mesh with each other, and the drive gear 10 meshes with an adjacent transmission gear 11. The intermittent feeding mechanism comprises a servo cylinder 12 fixedly installed on the front outer wall of the feeding hopper 6, a connecting rod 13 fixedly connected to the telescopic end of the servo cylinder 12, two feeding baffles 14 rotatably connected to the feeding hopper 6 through two rotating pins, two linkage gears 15 fixedly sleeved on the front ends of the two rotating pins in sequence, and two racks 16 symmetrically fixed to the outer walls of the two ends of the connecting rod 13. Further, the two racks 16 are respectively engaged with the two linkage gears 15, the two feeding baffles 14 are symmetrically arranged in the feeding hopper 6, the back ends of the two racks 16 are respectively fixed with guide members, and the front side of the feeding hopper 6 is symmetrically provided with two guide grooves 17, and the outer walls of the two guide members are respectively slidably connected with the inner walls of the two guide grooves 17. In the specific implementation of the embodiment, first, the waste generated in the PE displacement pipe processing process is poured into the feeding hopper 6 at one time, then the servo cylinder 12 drives the connecting rod 13 to move downward, and then the two racks 16 move downward to drive the two linkage gears 15 to rotate in opposite directions, and then the two feeding baffles 14 connected to the two rotating pins open downward to achieve the feeding effect; second, the servo cylinder 12 drives the connecting rod 13 to move upward, and then the two racks 16 move upward to drive the two feeding baffles 14 connected to the two rotating pins to close upward to achieve the effect of being unable to feed; finally, the driving motor 9 controls the driving gear 10 to rotate in the forward direction, and then the transmission gear 11 engaged with the driving gear 10 rotates in the reverse direction, and then the other transmission gear 11 rotates in the forward direction under the influence of meshing transmission, so that the two crushing knife rollers 7 rotate relatively to crush the waste entering from the feeding hopper 6. In summary: in the embodiment, the up-and-down reciprocating motion of the two racks 16 is controlled by the servo cylinder 12 to intermittently open the two feeding baffles 14, so that the waste in the feeding hopper 6 can enter the crushing chamber 5 little by little for crushing treatment, avoiding the situation that the crushing work of the machine cannot work normally due to excessive feeding amount, so as to ensure the crushing efficiency in the waste recovery process.

[0020] Embodiment 2, refer to Figure 1 , Figure 3 , Figure 5 and Figure 10 , the embodiment is optimized on the basis of embodiment 1, specifically: the circulating feeding mechanism comprises an electric overturning and pouring component, a vertical screw rod 18 rotatably installed on the support plate 1, a lifting block 19 threadedly connected to the lower part of the vertical screw rod 18, a servo motor 21 fixedly connected to the top outer wall of the support plate 1 through a motor base 20, and a visual sensor 34 fixedly installed on the top lower side wall of the support frame 3, the visual sensor 34 being an industrial camera. Furthermore, the electric tilting and unloading assembly includes two electric telescopic rods 23 symmetrically fixed to the side wall of the lifting block 19, a fixed plate 24 fixedly connected to the telescopic ends of the two electric telescopic rods 23, a tilting and unloading plate 25 hinged to the top of the fixed plate 24, a receiving box 26 fixedly installed on the top outer wall of the tilting and unloading plate 25, and two hydraulic rods 27 symmetrically hinged to the top of the fixed plate 24; furthermore, the telescopic ends of the two hydraulic rods 27 are both hinged to the bottom of the tilting and unloading plate 25, and the output shaft of the servo motor 21 is coaxially fixedly connected to the top end of the vertical lead screw 18 through a coupling; furthermore, two guide vertical shafts 22 are symmetrically welded to the left side area of ​​the support plate 1, and two guide holes are opened on the lifting block 19, with the two guide vertical shafts 22 slidably connected to the two guide holes respectively; In this embodiment, the following steps are taken: First, the vision sensor 34 captures the image information of the waste material discharged from the discharge hopper 4 onto the servo conveyor 2 and transmits the image information to the main control panel 35. The main control panel 35 determines whether the waste material is properly crushed. If the waste material is not properly crushed, the servo conveyor 2 controls the waste material to be conveyed to the left. At this time, the uncrushed waste material is guided into the receiving box 26 from the left guide frame 28. Second, the servo motor 21 controls the vertical screw 18 to rotate. Then, under the guidance of the two guide vertical shafts 22, the lifting block 19, which is threadedly connected to the vertical screw 18, drives the receiving box 26 to move upward to a high position. The two electric telescopic rods 23 push the receiving box 26 to the left edge of the feed hopper 6. Then, the two hydraulic rods 27 push the receiving box 26 downward to pour the waste material, so that the waste material re-enters the feed hopper 6 and is crushed again. Then, a reset operation is performed so that the receiving box 26 returns to the bottom and continues to repeat the above waste material recycling crushing work. In summary, this embodiment uses visual sensor 34 to automatically determine whether the crushing state of the waste material meets the standard using visual detection technology. The automatic cyclic feeding effect of the circulating feeding mechanism can automatically crush the substandard waste material multiple times, thereby improving the fineness of waste material crushing and ensuring the quality of waste material recycling.

[0021] Example 3, referring to Figure 3 , Figure 8 and Figure 9 This embodiment is an optimization based on embodiment 1. Specifically, the material receiving and recycling mechanism includes a bearing plate 30 fixedly connected to the bottom outer wall of the right guide frame 29, a slide groove opened on one side of the bearing plate 30, a bidirectional screw 31 rotatably installed in the slide groove, and two bag support plates 32 symmetrically screwed to the two opposite threaded ends of the bidirectional screw 31. Furthermore, the outer walls of the two bag support plates 32 are slidably connected to the inner wall of the slide groove. The limiting of the slide groove can ensure the stability of the linear movement of the two bag support plates 32. A handwheel 33 is fixedly connected to the outer wall of one end of the bidirectional screw 31, and the bidirectional screw 31 can be manually rotated through the handwheel 33. In the specific implementation of the embodiment, the hand wheel 33 is used to control the rotation of the bidirectional screw rod 31, and then under the limiting of the sliding groove, the two bag opening plates 32 connected with the bidirectional screw rod 31 by screw threads are away from each other to automatically open the waste recycling bag placed on the bearing plate 30, and then the waste conveyed to the right by the servo conveyor 2 can be more smoothly caught by the waste recycling bag through the right material guide frame 29, thereby effectively improving the efficiency of the waste recycling end material receiving work.

[0022] In combination with Embodiments 1-3, the application provides a waste crushing and recycling method of a waste crushing and recycling device for PE replacement pipe processing, which comprises the following steps: S1: The waste generated in the PE replacement pipe processing process is once poured into the feeding hopper 6, and then the up-down reciprocating movement of the two rack gears 16 is controlled by the servo cylinder 12 to intermittently open the two feeding baffles 14, so that the waste in the feeding hopper 6 can enter the crushing bin 5 little by little for crushing treatment, avoiding the situation that the crushing work of the machine cannot work normally due to excessive load caused by excessive feeding amount, thereby ensuring the crushing efficiency in the waste recycling process; S2: The driving assembly drives the relative rotation of the two crushing knife rollers 7 to crush the waste entering from the feeding hopper 6, and the crushed waste is discharged from the bottom of the discharging hopper 4 and falls on the servo conveyor 2; S3: The visual sensor 34 uses visual detection technology to automatically judge whether the waste crushing state on the servo conveyor 2 meets the standard, and the automatic circulating feeding effect of the circulating feeding mechanism can automatically send the waste that does not meet the standard back to the feeding hopper 6 for multiple cycle crushing, thereby improving the fineness of waste crushing and ensuring the waste recycling quality; S4: After multiple cycle crushing, the visual sensor 34 detects that the waste crushing is qualified, and then the servo conveyor 2 conveys the qualified waste to the right, and the waste can be smoothly caught by the material receiving and recycling mechanism through the right material guide frame 29 to complete the recycling.
