Description

Technical Field

[0001] This utility model relates to the field of automatic loading and unloading technology for garbage trucks, specifically an automatic loading and unloading mechanism for sanitation garbage trucks. Background Technology

[0002] With the acceleration of urbanization, the amount of waste generated has increased dramatically, and traditional waste collection methods can no longer meet the demands for efficiency and environmental protection. Therefore, self-loading and unloading garbage trucks have emerged and have gradually become an important part of urban sanitation work.

[0003] Existing self-loading garbage trucks raise the garbage bins and then tilt them to align them with the collection device when dumping garbage. However, it is difficult to empty all the garbage remaining at the bottom of the bins during dumping, resulting in some garbage remaining in the bins. This requires sanitation workers to manually clean the bins, increasing their workload. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic loading and unloading mechanism for sanitation garbage trucks to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic loading and unloading mechanism for sanitation garbage trucks, including a collection box, a lifting mechanism on the collection box, a fixing sleeve on one side of the collection box, a pushing column on the fixing sleeve, a connecting block at one end of the pushing column, a shrink plate on the collection box, and a shrink sleeve on the collection box.

[0006] The lifting mechanism includes two sets of baffles disposed inside the collection box. Each set of baffles is provided with a first fixing rod. A rotating roller is disposed through the first fixing rod, and an eccentric wheel is disposed through the rotating roller. A motor is also disposed on one side of the first fixing rod. The collection box is also provided with two sets of second fixing rods. A first gear is disposed through the two sets of second fixing rods. A second gear is disposed on one side of the first gear. A first rack is disposed on the upper end of the first gear. The first rack is disposed on one side of the baffle, and a second rack is disposed on one side of the second gear. The second rack is fixedly connected to the baffle.

[0007] Preferably, the lower end of the fixed sleeve is provided with two sets of telescopic push rods, and the inner side of the two sets of telescopic push rods is provided with a third fixed rod.

[0008] Preferably, the upper end of the fixing sleeve is provided with two sets of limiting rods, and one side of the limiting rods is arc-shaped.

[0009] Preferably, the connecting block is connected to the shrink plate, and the shrink sleeve has a first groove inside, the size of which is adapted to the shrink plate.

[0010] Preferably, the first gear meshes with the second rack, and the second gear meshes with the first rack.

[0011] Preferably, the shrink plate is provided with two sets of second grooves, the size of which is adapted to the baffle.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] As the baffle extends upwards, it moves the first fixed rod on the baffle upwards. When the trash can reaches its highest point and flips over, the bottom of the eccentric wheel contacts the upper wall of the trash can. At the same time, the motor is turned on, driving the rotating roller to rotate. The rotating roller drives the eccentric wheel to rotate, and the rotating eccentric wheel strikes the trash can, preventing some trash from remaining inside when dumping. This improves the efficiency of trash collection, avoids long-term trash residue at the bottom of the trash can causing pollution, and prevents workers from increasing their workload.

[0014] The connecting block pushes the shrink plate to move, which in turn moves the first rack. The movement of the first rack causes the first gear to rotate, which in turn causes the second gear to rotate. The rotation of the second gear causes the second rack to move, which in turn causes the baffle to move, extending the baffle out from the second groove on the shrink plate. This protects the trash can from spilling out when the trash is emptied, preventing the trash from polluting the environment and affecting the city's appearance during collection.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 5 This utility model provides an automatic loading and unloading mechanism for sanitation garbage trucks, including a collection box 1, a lifting mechanism 2 on the collection box 1, a fixing sleeve 11 on one side of the collection box 1, a pushing column 14 on the fixing sleeve 11, a connecting block 15 at one end of the pushing column 14, a shrink plate 16 on the collection box 1, and a shrink sleeve 161 on the collection box 1.

[0023] The lifting mechanism 2 includes two sets of baffles 21 disposed inside the collection box 1. Each set of baffles 21 is provided with a first fixing rod 22. A rotating roller 23 is disposed through the first fixing rod 22. An eccentric wheel 24 is disposed through the rotating roller 23. A motor 221 is also disposed on one side of the first fixing rod 22. The collection box 1 is also provided with two sets of second fixing rods 25. A first gear 251 is disposed through the two sets of second fixing rods 25. A second gear 252 is disposed on one side of the first gear 251. A first rack 26 is disposed at the upper end of the first gear 251. The first rack 26 is disposed on one side of the baffle 21. A second rack 27 is disposed on one side of the second gear 252. The second rack 27 is fixedly connected to the baffle 21.

[0024] Before using this device, the worker fixes the trash can to be cleaned using the fixing sleeve 11. The telescopic push rod 12 extends, causing the fixing sleeve 11 to move along an arc on the limiting rod 13. When it reaches the top, the arc causes the trash can, fixed by the fixing sleeve 11, to flip at a certain angle. Simultaneously, the fixing sleeve 11 moves, causing the push column 14 to move. The push column 14 moves and presses against the connecting block 15, causing the shrink plate 16 to move into the groove inside the shrink sleeve 161, causing the top of the collection box 1 to leak out. The trash in the trash can then leaks out through the opening of the shrink plate 16. The trash can is poured into the collection box 1. At the same time, the connecting block 15 pushes the shrink plate 16 to move, which in turn moves the first rack 26. The movement of the first rack 26 causes the first gear 251 to rotate. The rotation of the first gear 251 causes the second gear 252 to rotate. The rotation of the second gear 252 causes the second rack 27 to move. The movement of the second rack 27 causes the baffle 21 to move, extending the baffle 21 from the second groove on the shrink plate 16. This protects the trash can from spilling when it is emptied, preventing the trash from polluting the environment and affecting the city's appearance.

[0025] Simultaneously, as the baffle 21 extends upward, it drives the first fixed rod 22 on the baffle 21 to move upward. When the trash can moves to the highest point and flips over, the bottom of the eccentric wheel 24 contacts the upper wall of the trash can. At the same time, the motor 221 is turned on, driving the rotating roller 23 to rotate. The rotating roller 23 drives the eccentric wheel 24 to rotate, and the rotating eccentric wheel 24 strikes the trash can, preventing some trash from remaining inside the trash can when dumping, thus enhancing the efficiency of trash collection, preventing trash from remaining at the bottom of the trash can for a long time and causing pollution, and reducing the workload of workers.

[0026] In an optional embodiment, the lower end of the fixed sleeve 11 is provided with two sets of telescopic push rods 12, and the inner side of the two sets of telescopic push rods 12 is provided with a third fixed rod 121.

[0027] It should be noted that the telescopic push rod 12 extends and retracts, causing the fixed sleeve 11 to move, which in turn moves the trash can, moving the trash can fixed on the fixed sleeve 11 to a higher position for emptying. At the same time, the third fixed rod 121 is used to enhance the effect of the telescopic push rod 12, prevent the telescopic push rod 12 from being damaged due to long-term use, and enhance the fixing effect on the trash can.

[0028] In an optional embodiment, the upper end of the fixing sleeve 11 is provided with two sets of limiting rods 13, one side of which is arc-shaped.

[0029] It should be noted that the telescopic push rod 12 telescopically adjusts the fixed sleeve 11 to move on the limiting rod 13. The limiting rod 13 is provided with an arc shape to assist the trash can in flipping over when it is moved to a high position, so that the trash in the trash can can be directly poured into the collection box 1 for collection.

[0030] In an optional embodiment, the connecting block 15 is connected to the shrink plate 16, and the shrink sleeve 161 has a first groove inside, the size of which is adapted to the shrink plate 16.

[0031] It should be noted that the movement of the push column 14 causes the connecting block 15 to move, and the movement of the connecting block 15 causes the shrink plate 16 to move, moving the shrink plate 16 into the shrink sleeve 161, so that the garbage can be directly dumped into the collection box 1.

[0032] In an optional embodiment, the first gear 251 meshes with the second rack 27, and the second gear 252 meshes with the first rack 26.

[0033] It should be noted that the movement of the shrink plate 16 causes the first rack 26 to move, the movement of the first rack 26 causes the first gear 251 to rotate, the rotation of the first gear 251 causes the second gear 252 to rotate, and the rotation of the second gear 252 causes the second rack 27 to move.

[0034] In an optional embodiment, the shrink plate 16 is provided with two sets of second grooves, the dimensions of which are adapted to the baffle 21.

[0035] It should be noted that the movement of the second rack 27 causes the baffle 21 to move, extending the baffle 21 out from the second groove on the shrink plate 16, thus protecting the trash can from spilling out when the trash can is emptied.

[0036] Working principle: Before using this device, the worker fixes the trash can to be cleaned using the fixing sleeve 11. The telescopic push rod 12 extends, causing the fixing sleeve 11 to move along an arc on the limiting rod 13. When it reaches the top, the arc causes the trash can fixed by the fixing sleeve 11 to flip at a certain angle. At the same time, the fixing sleeve 11 moves, causing the push column 14 to move. The push column 14 moves and squeezes the connecting block 15, causing the shrink plate 16 to move into the groove inside the shrink sleeve 161, so that the top of the collection box 1 is exposed, and the trash in the trash can shrinks and opens from the shrink plate 16. The garbage is poured into the collection bin 1 through the opening. At the same time, the connecting block 15 pushes the shrink plate 16 to move, which in turn moves the first rack 26. The movement of the first rack 26 causes the first gear 251 to rotate. The rotation of the first gear 251 causes the second gear 252 to rotate. The rotation of the second gear 252 causes the second rack 27 to move. The movement of the second rack 27 causes the baffle 21 to move, extending the baffle 21 from the second groove on the shrink plate 16. This protects the garbage bin from spilling when it is emptied, preventing garbage from spilling during collection and causing environmental pollution, which would affect the appearance of the city.

[0037] Simultaneously, as the baffle 21 extends upward, it drives the first fixed rod 22 on the baffle 21 to move upward. When the trash can moves to the highest point and flips over, the bottom of the eccentric wheel 24 contacts the upper wall of the trash can. At the same time, the motor 221 is turned on, driving the rotating roller 23 to rotate. The rotating roller 23 drives the eccentric wheel 24 to rotate, and the rotating eccentric wheel 24 strikes the trash can, preventing some trash from remaining inside the trash can when dumping, thus enhancing the efficiency of trash collection, preventing trash from remaining at the bottom of the trash can for a long time and causing pollution, and reducing the workload of workers.

[0038] The telescopic push rod 12 extends and retracts, causing the fixed sleeve 11 to move, which in turn moves the trash can, moving the trash can fixed on the fixed sleeve 11 to a higher position for dumping. At the same time, the third fixed rod 121 is used to enhance the effect of the telescopic push rod 12, preventing damage caused by prolonged use of the telescopic push rod 12, and also enhancing the fixing effect on the trash can. The telescopic push rod 12 extends and retracts, causing the fixed sleeve 11 to move on the limiting rod 13. The limiting rod 13 is provided with an arc to assist the trash can in flipping over when it is moved to a higher position, directly dumping the trash in the trash can into the collection box 1 for collection. The push column 14 moves, causing the connecting block 15 to move, and the connecting block 15 moves, causing the shrink plate 16 to move, moving the shrink plate 16 into the shrink sleeve 161, making it easy to directly dump the trash into the collection box 1.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
