The flipping mechanism 21 is connected to the hydraulic station 4, and the hydraulic station 4 provides power for the flipping mechanism 21. The control device 5 is connected to the hydraulic station 4 and is used to control the hydraulic station 4 to work.

[0024] Specific:

[0025] The hanging plate assembly 2 also includes a hanging plate central axis 22, a hanging plate bracket 23 and a cover plate device 24. The hanging plate bracket 23 is welded on the hanging plate central axis 22. The hanging plate bracket 23 has a hanging tooth 231. The groove of the edge of the trash can is inserted into the hanging tooth 231 so as to be hung on the hanging plate bracket 23. There is a cover plate device 24 above the hanging tooth 231. When the hanging plate bracket 23 is at the lower limit position, the cover plate device 24 opens. When the hanging plate bracket 23 is lifted, the cover plate device 24 automatically closes at the edge of the trash can, realizing the automatic locking of the trash can edge to prevent the trash can from falling during the flipping process. Figure 2 As shown, the hanging plate bracket 23 includes a vertical rod 232, a first square tube 233 and a channel steel 234. A plurality of vertically parallel vertical rods 232 are sleeved on the hanging plate central axis 22, welded to the hanging plate central axis 22, and flipped as the hanging plate central axis 22 rotates. In the present invention, the vertical rods 232 are preferably 4. The first square tube 233 is welded to the upper end of each vertical rod 232, and three sets of hanging teeth 231 are fixedly arranged in front of the first square tube 233, so that three trash cans can be hung at the same time. The channel steel 234 is welded to the lower end of each vertical rod 232, and the channel steel 234 is used to contact the trash can body during the trash can flipping process to play a supporting role. Preferably, the channel steel 234 has a D-shaped anti-collision strip 235 to prevent the trash can from being scratched. The cover device 24 includes a connecting rod 241, a connecting arm 242, a rotating bearing 243, a tensioning mechanism 244 and an angle steel 245. The connecting arm 242 is a two-section bending structure, the angle steel 245 is a long strip, and the cross section is an L-shaped right-angle opening structure. One end of the connecting arm 242 is welded to the back of the opening of the angle steel 245, and the other end is connected to the rotating bearing 243. One end of the connecting rod 241 is welded to the back of the first square tube 233, and the other end is connected to the waist axis of the connecting arm 242. The connecting arm 242 rotates around the waist connecting axis to drive the angle steel 245 to open or close. The tensioning mechanism 244 is located between the two trash cans. The tensioning mechanism 244 includes a spring fixing part 2441 connected to the two middle vertical rods 232, a spring 2442, and a hanging rod 2443 fixed above the angle steel. One end of the spring 2442 is hinged on the spring fixing part 2441, and the other end is suspended on the hanging rod 2443. The front of the discharge hopper assembly 1 near the connecting arm 242 has a second square tube 13. When the hanging plate assembly 2 is at the lower limit position, the lower end of the connecting arm 242 abuts against the second square tube 13. Using the principle of lever, the upper end of the connecting arm 242 tilts up, and the angle steel 245 opens upward, in an "open state". At this time, the spring 2442 is stretched; when the hanging plate assembly 2 is lifted upward, the lower end of the connecting arm 242 is out of contact with the second square tube 13, and the angle steel 245 automatically closes downward under the tension of the spring 2442, in a "closed state", locking the edge of the trash can to prevent the trash can from falling during the flipping process. The function of the rotating bearing 243 is to reduce the friction between the connecting arm 242 and the central axis 22 of the hanging plate.

[0026] The flip mechanism 21 includes a large support 211, a large swing arm 212, a small swing arm 213, a small swing arm 214, a connecting rod 215, a pin 216, and a cylinder 217, which are symmetrically arranged on the left and right sides. The large support 211 and the small support 213 are bolted in parallel to the outside of the side plate 11 of the discharge hopper assembly 1, one end of the large swing arm 212 and the small swing arm 214 are axially connected to the large support 211 and the small support 213 respectively, the other end of the large swing arm 212 is connected to the end of the hanging plate central axis 22 through the pin 216, the other end of the small swing arm 214 is axially connected to one end of the connecting rod 215, the other end of the connecting rod 215 is sleeved with the hanging plate central axis 22, and is keyed to the hanging plate central axis 22, limiting the relative movement of the connecting rod 215 and the hanging plate central axis 22, thereby ensuring that the left and right movement of the flip mechanism remains consistent. One end of the oil cylinder 217 is connected to the waist axis of the large swing arm 212, and the other end is connected to the hydraulic station 4 through the conduit 218. The oil cylinder 217 is extended and retracted to drive the large swing arm 212 to lift and the small swing arm 214 to lift, completing the 150-degree flip of the hanging plate bracket 23. Preferably, the surface of the pin shaft 216 has an oil injection hole 2161, through which grease can be added to the joint bearing.

[0027] The control device 5 includes a control box 51 and a positioning device 52. The positioning device 52 includes two groups of beamforming sensors, namely a first group of beamforming sensors 521 and a second group of beamforming sensors 522. The first group of beamforming sensors 521 is set on the ground to detect the lowest position of the trash can, and the second group of beamforming sensors 522 is set on the top of the side plate 11 of the discharge hopper assembly 1 to detect the highest position of the trash can. The control box 51 contains a control system, which determines the turning state of the trash can according to the signal detected by the positioning device 52. For the convenience of operation, a control button box 511 is introduced into the control box 51. The control button box 511 is used to manually or automatically control the operation of the trash can turning machine. The control box 51 includes a solenoid valve and a PLC system. The control system controls the power on and off of the coils at both ends of the solenoid valve through the PLC system to realize the shaking function of the hanging plate assembly 2.

[0028] In order to further prevent the problem of difficulty in taking out the trash can in case it falls into the discharge hopper. The present invention has also made some improvements. A column assembly 3 is set at the outer bottom of the side panel 11 of the discharge hopper assembly 1. The column assembly 3 includes columns 31 fixedly connected to the ground on both sides of the turning machine and cylindrical pin holes 32 hinged to the outer bottom of the side panel 11. The columns 31 and the cylindrical pin holes 32 are hingedly connected through pins. Casters 15 are installed at the bottom of the discharge hopper assembly 1, and a pull rod 16 is provided between the upper and lower side panels on the front of the discharge hopper assembly 1. Pull rings 161 are installed at the left and right ends of the pull rod 16. When the trash can accidentally falls into the discharge hopper or the equipment needs to be cleaned and repaired, the column assembly 3 can be opened, the pull ring 161 can be pulled, and the turning machine can be moved.

[0029] like Figure 3-5As shown, when in use, manually hang the trash can on the hanging teeth 231 of the hanging plate assembly 2, and then press the start button of the control button box 511. The first group of shooting sensors 521 detects the trash can, and then the hydraulic station 4 is started to provide a power source to the flip mechanism 21. The flip mechanism 21 lifts and flips the hanging plate bracket 23. During the lifting process, the lower end of the connecting arm 242 of the cover device 24 is out of contact with the second square tube 13, and the angle steel 245 is automatically closed downward under the elastic force of the spring 2442, which is in a "closed state", locking the edge of the trash can to prevent the trash can from falling during the flipping process. When the trash can rotates to the highest position, the second group of shooting sensors 522 detects the trash can, and the control device 5 controls the power of the coils at both ends of the solenoid valve through the PLC system to achieve the shaking of the hanging plate assembly 2, and shake the garbage into the discharge hopper. The control device 5 controls the flipping mechanism 21 to reverse and reset the empty trash can. When the trash can drops to the lowest limit, the lower end of the connecting arm 242 of the cover device 24 contacts the second square tube 13, and the angle steel 245 opens automatically. At this time, the above actions can be repeated to complete the garbage dumping.
