[0006] As a further solution of the present invention, the placement table is fixedly welded to the bottom side of the control frame. Connecting shafts are fixedly installed on both sides of the control frame. The top ends of the connecting shafts penetrate the fixing frame and extend into the fixed cover.

A driving motor is fixedly installed in the fixed cover by bolts. The output end of the driving motor is fixedly connected to the worm. The driving motors in the two fixed covers are started through a synchronizer to ensure synchronous rotation.

[0007] As a further solution of the present invention, a movable groove is formed at the top of the placement table, a rotating rod is movably installed in the movable groove, opposite threads are formed on both sides of the rotating rod, the clamping plates are arranged at both ends of the rotating rod, the clamping plates are threadedly connected to the rotating rod, a friction pad is fixedly installed on the inner side of the clamping plate, the friction pad protrudes from the surface of the clamping plate, a first bevel gear is also fixedly installed on the rotating rod, a servo motor is fixedly installed in the placement table, and a second bevel gear is fixedly installed on the output shaft of the servo motor, and the second bevel gear meshes with the first bevel gear.

[0008] As a further solution of the present invention, a control motor is fixedly installed at the position corresponding to the telescopic rod in the connection cover, the output end of the control motor is connected to the bottom of the telescopic rod, the telescopic rod can be driven to work by the control motor, a fixing ring is arranged on the outer side of the telescopic rod, the outer side of the fixing ring is fixedly connected to the connection frame, a spiral groove is formed on the upper side wall of the telescopic rod, the inner side of the fixing ring can be engaged with the spiral groove, and the telescopic end at the top of the telescopic rod is movably connected to the connection frame.

[0009] As a further solution of the present invention, folding rods are movably installed at the tops of the scraping plates on both sides of the connection frame, a connecting rod is fixedly installed on the side of the scraping plate close to the connection frame, a groove is formed on the connection frame corresponding to the connecting rod, the connecting rod can be movably installed in the corresponding groove on the connection frame, and a spring is fixedly installed between the scraping plate and the connection frame.

[0010] As a further solution of the present invention, a diversion groove is formed at the inner bottom of the transfer box, and holes are equidistantly formed in the diversion groove.

[0011] As a further solution of the present invention, a sewage discharge pipe is fixedly connected to the side wall of the sewage tank, and a control valve is installed on the sewage discharge pipe.

[0012] A use method of a solid waste transfer device includes the following steps: S1: When in use, the device is moved to the side of the trash can that needs to recycle solid waste through the movable wheels, and then the trash can is moved onto the placement table and placed. The controller can control the servo motor to start. The servo motor can drive the second bevel gear to rotate. The second bevel gear meshes with the first bevel gear to drive the rotating rod to rotate. When the rotating rod rotates, it can control the clamping plates to clamp both sides of the trash can for fixation. At the same time, the friction pad on the clamping plate can also increase the friction with the barrel wall, clamp the trash can more firmly, and prevent it from falling off during subsequent movement; S2: After the clamping is completed, the synchronizer connected to the controller controls the synchronous start of the drive motor in the fixed cover. When the drive motor rotates, it can drive the worm to rotate. The worm meshes with the worm wheel, and the worm can drive the worm wheel to control the rotation of the connecting shaft. The connecting shaft is connected to the control frame, so as to drive the trash can on the placement table to rotate continuously. When the control frame rotates to the top, the trash can can be flipped 180°, so that the mouth of the trash can is aligned with the feeding port. At this time, the solid waste in the trash can will automatically fall into the transfer box by gravity, thus avoiding the situation that the garbage cannot be completely emptied and requires manual cleaning. At the same time, due to the self-locking effect between the worm wheel and the worm, it can avoid the situation that the trash can is too heavy, resulting in the motor being unable to drive the trash can to fall and cause harm to the surrounding workers. S3: When the solid waste in the trash can adheres to the inside of the trash can, the controller starts the control motor to control the telescopic end of the telescopic rod to drive the connecting frame to rise. The connecting frame will drive the scraper and the folding rod to move up into the trash can together. Since the folding rod is triangular and movably connected to the scraper, when the side of the folding rod contacts the trash can, it will drive the scraper to retract inward, so that it can enter trash cans of different sizes for cleaning. After the scraper enters the trash can, the elasticity of the spring will push the scraper against the inner wall of the trash can. At the same time, when the telescopic rod drives the connecting frame to move up, the fixed ring connected to the connecting frame engages with the spiral groove outside the telescopic rod. When the fixed ring moves up on the outside of the telescopic rod, it will drive the connecting frame to rotate, so as to drive the scraper to scrape and clean the inner wall of the trash can, and clean out the adhered solid waste, without the need for workers to use tools to assist in cleaning, which is very convenient. S4: When the solid waste enters through the feeding port, the guiding platform can guide the solid waste to the storage place in the transfer box. When the solid waste accumulates in the transfer box, the diversion groove at the bottom of the transfer box can guide the liquid remaining in the solid waste. The remaining liquid can flow into the sewage tank through the holes in the diversion groove for collection, avoiding the leakage of the liquid from the device connection during movement and spilling on the ground to pollute the environment. S5: After reaching the designated position, the back of the transfer box can be opened by pulling out the movable door from the chute, which is convenient for taking out the solid waste from the transfer box. S6: By opening the control valve on the sewage discharge pipe, the waste liquid collected in the sewage tank can be discharged, which is convenient for centralized treatment.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, when the driving motor rotates, it can drive the worm to rotate. The worm meshes with the worm wheel, and the worm can drive the worm wheel to control the rotation of the connecting shaft. The connecting shaft is connected to the control frame, so as to drive the trash can on the placing table to rotate continuously. When the control frame rotates to the top, the trash can can be flipped 180°, so that the mouth of the trash can is aligned with the feeding port. At this time, the solid waste in the trash can will automatically fall into the transfer box by gravity, thus avoiding the situation where the garbage cannot be completely emptied and manual cleaning is required.

[0014] 2. In the present invention, by starting the control motor to control the telescopic end of the telescopic rod to drive the connecting frame to rise, the connecting frame will drive the scraper and the folding rod to move up into the trash can together. At the same time, when the telescopic rod drives the connecting frame to move up, the fixed ring connected to the connecting frame is engaged with the spiral groove outside the telescopic rod. When the fixed ring moves up outside the telescopic rod, it will drive the connecting frame to rotate, so as to drive the scraper to scrape and clean the inner wall of the trash can, and clean out the adhered solid waste, without the need for workers to use tools to assist in cleaning, which is very convenient.

[0019] In this embodiment, the placing table 10 is fixedly welded to the bottom side of the control frame 17. Connecting shafts 16 are fixedly installed on both sides of the control frame 17.

The output end of the driving motor 15 is fixedly connected to the worm 14. The driving motors 15 in the two fixing covers 12 are started through a synchronizer to ensure synchronous rotation. The driving motors 15 in the fixing covers 12 are controlled to start synchronously through the synchronizer connected to the controller 6. When the driving motor 15 rotates, it can drive the worm 14 to rotate. Since the worm 14 meshes with the worm gear 13, the worm 14 can drive the worm gear 13 to control the rotation of the connecting shaft 16. And the connecting shaft 16 is connected to the control frame 17, so that the trash can on the placing table 10 can be continuously rotated. When the control frame 17 rotates to the top, the trash can can be flipped 180°, aligning the mouth of the trash can with the feeding port 7. At this time, the solid waste in the trash can will automatically fall into the transfer box 1 by gravity.

[0020] In this embodiment, an activity groove 19 is formed in the top of the placing table 10. A rotating rod 20 is movably installed in the activity groove 19. Opposite threads are formed on both sides of the rotating rod 20. Clamping plates 11 are arranged at both ends of the rotating rod 20. The clamping plates 11 are in threaded connection with the rotating rod 20. A friction pad 18 is fixedly installed on the inner side of the clamping plate 11. The friction pad 18 protrudes from the surface of the clamping plate 11. A first bevel gear 22 is also fixedly installed on the rotating rod 20.

The meshing of the second bevel gear 23 and the first bevel gear 22 can drive the rotating rod 20 to rotate. When the rotating rod 20 rotates, it can control the clamping plates 11 to clamp both sides of the trash can for fixation. The friction pad 18 on the clamping plate 11 can also increase the friction force with the barrel wall, clamping the trash can more firmly and preventing it from falling off during subsequent movement.

[0021] In this embodiment, a control motor 27 is fixedly installed at a position corresponding to the telescopic rod 26 in the connecting cover 25. The output end of the control motor 27 is connected to the bottom of the telescopic rod 26. The telescopic rod 26 can be driven to work by the control motor 27. A fixing ring 34 is arranged on the outer side of the telescopic rod 26. The outer side of the fixing ring 34 is fixedly connected to the connecting frame 28. A spiral groove 33 is formed on the upper side wall of the telescopic rod 26. The inner side of the fixing ring 34 can be engaged with the spiral groove 33. The telescopic end at the top of the telescopic rod 26 is movably connected to the connecting frame 28. Folding rods 30 are movably installed at the tops of the scraping plates 29 on both sides of the connecting frame 28. A connecting rod 31 is fixedly installed on the side of the scraping plate 29 close to the connecting frame 28. A groove is formed on the connecting frame 28 corresponding to the connecting rod 31. The connecting rod 31 can be movably installed in the corresponding groove on the connecting frame 28. A spring 32 is fixedly installed between the scraping plate 29 and the connecting frame 28. By starting the control motor 27 through the controller 6, the telescopic end of the telescopic rod 26 is controlled to drive the connecting frame 28 to rise. The connecting frame 28 will drive the scraping plate 29 and the folding rods 30 to move upward into the trash can together. Since the folding rods 30 are triangular and movably connected to the scraping plate 29, when the side of the folding rod 30 contacts the trash can, it will drive the scraping plate 29 to fold inward, so that it can enter trash cans of different sizes for cleaning. When the scraping plate 29 enters the trash can, the elasticity of the spring 32 will push the scraping plate 29 against the inner wall of the trash can. At the same time, when the telescopic rod 26 drives the connecting frame 28 to move upward, the fixing ring 34 connected to the connecting frame 28 is engaged with the spiral groove 33 on the outer side of the telescopic rod 26. When the fixing ring 34 moves upward on the outer side of the telescopic rod 26, it will drive the connecting frame 28 to rotate, so that the scraping plate 29 can be driven to scrape and clean the inner wall of the trash can.

[0022] In this embodiment, a diversion groove 35 is formed at the inner bottom of the transfer box 1. Holes are equidistantly formed in the diversion groove 35. The liquid remaining in the solid waste can be guided through the diversion groove 35 at the inner bottom of the transfer box 1. The remaining liquid can flow into the sewage tank 2 through the holes in the diversion groove 35 for collection, so as to avoid leakage of the liquid from the device connection during movement and spillage on the ground to pollute the environment.

[0023] In this embodiment, a sewage discharge pipe 4 is fixedly connected to the side wall of the sewage tank 2. A control valve is installed on the sewage discharge pipe 4. The waste liquid collected in the sewage tank 2 can be discharged by opening the control valve on the sewage discharge pipe 4, which is convenient for centralized treatment.

[0024] A method for using a solid waste transfer device includes the following steps: During use, the device is moved to the side of the trash can that needs to recycle solid waste by the movable wheel 3, and then the trash can is carried onto the placement table 10 and placed. The controller 6 can control the servo motor 21 to start. The servo motor 21 can drive the second bevel gear 23 to rotate. The second bevel gear 23 meshes with the first bevel gear 22 to drive the rotating rod 20 to rotate. When the rotating rod 20 rotates, it can control the clamping plates 11 to clamp both sides of the trash can for fixation. At the same time, the friction pads 18 on the clamping plates 11 can also increase the friction force with the barrel wall, clamping the trash can more firmly to prevent it from falling off during subsequent movement; After the clamping is completed, the drive motors 15 in the fixed cover 12 are controlled to start synchronously through the synchronizer connected to the controller 6. When the drive motors 15 rotate, they can drive the worm 14 to rotate. The worm 14 meshes with the worm gear 13, and the worm 14 can drive the worm gear 13 to control the connecting shaft 16 to rotate. The connecting shaft 16 is connected to the control frame 17, so as to drive the trash can on the placement table 10 to rotate continuously. When the control frame 17 rotates to the top, it can flip the trash can 180°, aligning the mouth of the trash can with the feed inlet 7. At this time, the solid waste in the trash can will automatically fall into the transfer box 1 due to gravity, thus avoiding the situation where the garbage cannot be completely emptied and requires manual cleaning; at the same time, due to the self-locking effect between the worm gear 13 and the worm 14, it can avoid the situation where the trash can is too heavy, causing the motor to be unable to drive the trash can to fall and harming the surrounding workers; When the solid waste in the trash can adheres to the inside of the trash can, the controller 6 starts the control motor 27 to control the telescopic end of the telescopic rod 26 to drive the connecting frame 28 to rise. The connecting frame 28 will drive the scraper 29 and the folding rod 30 to move up into the trash can together. Since the folding rod 30 is triangular and is movably connected to the scraper 29, when the side of the folding rod 30 contacts the trash can, it will drive the scraper 29 to retract inward, so as to be able to enter trash cans of different sizes for cleaning. After the scraper 29 enters the trash can, the elasticity of the spring 32 will push the scraper 29 against the inner wall of the trash can. At the same time, when the telescopic rod 26 drives the connecting frame 28 to rise, the fixed ring 34 connected to the connecting frame 28 engages with the spiral groove 33 on the outside of the telescopic rod 26. When the fixed ring 34 moves up on the outside of the telescopic rod 26, it will drive the connecting frame 28 to rotate, so as to drive the scraper 29 to scrape and clean the inner wall of the trash can, cleaning out the adhered solid waste, and there is no need for workers to use tools to assist in cleaning, which is very convenient; When the solid waste enters through the feed inlet 7, the guide table 24 can guide the solid waste to the storage area in the transfer box 1. When the solid waste accumulates in the transfer box 1, the diversion groove 35 at the bottom of the transfer box 1 can guide the liquid remaining in the solid waste. The liquid remaining can flow into the sewage tank 2 through the holes in the diversion groove 35 for collection, avoiding the leakage of the liquid from the connection parts of the device during movement and spilling on the ground to pollute the environment; After reaching the designated position, the back of the transfer box 1 can be opened by pulling out the movable door 5 from the chute 36, facilitating the removal of solid waste from the transfer box 1. Then, by opening the control valve on the sewage discharge pipe 4, the waste liquid collected in the sewage tank 2 can be discharged for centralized treatment.

[0025] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

At the same time, the self-locking effect between the worm wheel (13) and the worm (14) can avoid the situation that the garbage can is too heavy, causing the motor to be unable to drive the garbage can to fall and cause injuries to surrounding workers. S3: When solid waste in the trash can adheres to the trash can, the controller (6) starts the control motor (27) to control the telescopic end of the telescopic rod (26) to drive the connecting frame (28) to rise, and the connecting frame (28) drives the scraper (29) and the folding rod (30) to move upward together and enter the trash can. Since the folding rod (30) is triangular and movably connected to the scraper (29), when the side of the folding rod (30) contacts the trash can, it drives the scraper (29) to retract inward, so that it can enter trash cans of different sizes for cleaning. When the scraper (29) enters the trash can, After the waste is in the trash can, the elasticity of the spring (32) pushes the scraper (29) to be close to the inner wall of the trash can. At the same time, when the telescopic rod (26) drives the connecting frame (28) to move upward, the fixing ring (34) connected to the connecting frame (28) is engaged with the spiral groove (33) on the outer side of the telescopic rod (26). When the fixing ring (34) moves upward on the outer side of the telescopic rod (26), it drives the connecting frame (28) to rotate, thereby driving the scraper (29) to scrape and clean the inner wall of the trash can, thereby cleaning out the adhered solid waste. It is very convenient without the need for workers to use tools to assist in cleaning. S4: When solid waste enters from the feed port (7), the solid waste can be guided to the storage area in the transfer box (1) through the guide platform (24). When the solid waste is accumulated in the transfer box (1), the liquid remaining in the solid waste can be guided through the guide groove (35) at the bottom of the transfer box (1). The remaining liquid can flow into the sewage tank (2) through the holes in the guide groove (35) for collection, thereby preventing the liquid from leaking from the connection of the device during movement and spilling on the ground to pollute the environment; S5: After reaching the designated position, the back of the transfer box (1) can be opened by pulling the movable door (5) out of the chute (36), so that the solid waste can be taken out of the transfer box (1); S6: By opening the control valve on the sewage pipe (4), the waste liquid collected in the sewage tank (2) can be discharged for centralized treatment.
