Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Such as Figures 1-9As shown in the figure, the present utility model provides a technical solution: a self-loading and unloading garbage truck, which includes an automobile chassis 1 and a carriage 2 disposed on the automobile chassis 1. The tail end of the carriage 2 is retracted forward at the bottom to form an inclined surface. The top of the tail of the carriage 2 is a feeding port. A self-loading and unloading system 3 is disposed at the tail of the carriage 2 on the automobile chassis 1. The self-loading and unloading system 3 includes a mounting frame 31 fixed to the automobile chassis 1, a tipping frame 32 hinged to the mounting frame 31, a tipping oil cylinder 33 for driving the tipping frame 32 to tip, and a lifting oil cylinder 34 for driving the carriage 2 to tip. The angle at which the carriage 2 is driven by the lifting oil cylinder 34 to tip upward is 80°. One end of the lifting oil cylinder 34 is hinged to the bottom of the tail end of the carriage 2, and the other end is hinged to the middle of the mounting frame 31. Moreover, the lifting oil cylinder 34 is located above the front of the tipping oil cylinder 33. An oil cylinder support leg 5 is disposed on the automobile chassis 1, which can be jacked downward to support on the ground to maintain the balance and stability of the vehicle when the carriage 2 tips upward. The tipping of the tipping frame 32 of the self-loading and unloading system 3 and the tipping of the carriage 2 can be completed by only one oil cylinder each, with fewer hydraulic control pipelines, lower manufacturing and maintenance costs. The hinged position of the lifting oil cylinder 34 and the design of the carriage 2 result in a large tipping angle of the carriage 2, a short action stroke of the lifting oil cylinder 34, which is more stable while saving the stroke, and a large tipping angle of the carriage 2, improving the completeness of the garbage tipping work;

[0029] The angle at which the tipping frame 32 is driven by the tipping oil cylinder 33 to tip upward is 145°. The tipping frame 32 includes a driving arm 321, a driven arm 322, a bucket hanging frame 323, and a bucket clamping mechanism 324 disposed on the bucket hanging frame 323. The linear distance between the two ends of the driving arm 321 is greater than the linear distance between the two ends of the driven arm 322. Both the driving arm 321 and the driven arm 322 are curved rods. The tops of the driving arm 321 and the driven arm 322 are hinged to the mounting frame 31 one after the other, and the middle upper part of the tail end of the carriage 2 is hinged to the mounting frame 31 and is hinged to the same axis as the top end of the driven arm 322. The bottom ends of the driving arm 321 and the driven arm 322 are hinged to the bucket hanging frame 323 one above the other. The driving arm 321, the driven arm 322, and the bucket hanging frame 323 hinged to the mounting frame 31 together form a crank-rocker mechanism. The upper end of the tipping oil cylinder 33 is hinged to the middle upper part of the driving arm 321, and the lower end is obliquely hinged forward to the automobile chassis 1. The hinged position of the tipping oil cylinder 33 and the design of the tipping frame 32 of the crank-rocker mechanism result in a large tipping angle of the trash can 4, a large tipping angle of the trash can 4, improving the completeness of the garbage tipping work;

[0030] The barrel clamping mechanism 324 includes a slidable barrel hanging plate 3241, a lifting cylinder 3242 whose two ends are respectively hinged on the barrel hanging frame 323 and the barrel hanging plate 3241, and a barrel clamping plate 3243 fixed on the top of the barrel hanging frame 323 and corresponding to the barrel hanging plate 3241 up and down. The barrel hanging plate 3241 is driven by the lifting cylinder 3242 to slide upward and clamp the barrel clamping plate 3243 on the top of the trash can 4. The barrel hanging plate 3241 is hung on the trash can 4 by a vertical plate protruding upward. The vertical plate is located below the edge of the mouth extending from the top of the trash can 4 on the ground. The lower vertical plate is inserted upward into the groove of the edge of the mouth extending from the top of the trash can 4, and is driven by the lifting cylinder 3242 to lift the trash can 4 hung on the vertical plate to the position of the clamping barrel plate 3243 and be clamped. A low-position hanging barrel is adopted, and the rising barrel hanging plate 3241 and the upper clamping barrel plate 3243 are clamped together to clamp the trash can 4, making it simple to hang and unload the trash can 4. The trash can 4 can be easily hung and unloaded on the ground, reducing manual auxiliary steps, and the trash can 4 is clamped and then lifted and turned over to pour out the garbage, ensuring stability and balance when dumping the trash can 4, thereby improving safety.

[0031] When the garbage can 4 is loaded and unloaded, the hanging barrel rack 323 is at the bottom, and the hanging barrel plate 3241 is lower than the edge of the garbage can 4. The garbage truck is driven to the position of the garbage can 4 close to the hanging barrel rack 323, and then the lifting cylinder 3242 lifts the hanging barrel plate 3241. During the lifting process, the hanging barrel plate 3241 hooks the groove at the edge of the garbage can 4 and lifts the garbage can 4 so that it is close to the hanging barrel plate 3241 and clamps the garbage can 4. Then the turning cylinder 33 is actuated to drive the active arm 321 and the driven arm 322 to rotate with the top hinges as the rotating shafts, and the turning rack 32 drives the garbage can 4 to be lifted and turned upward. During the turning process, the hanging barrel rack 323 supports the side wall of the garbage can 4, so that the bottom of the garbage can 4 is lifted to a position higher than the edge of the garbage can 4. At this time, the garbage can 4 is turned into place, and the garbage can 4 is aimed at the loading port on the top of the car 2 to dump the garbage, and then the reverse action is performed, and the garbage can 4 falls back to the ground with the rotation of the turning rack 32.

[0032] At the starting state of dumping the carriage 2, the lifting cylinder 34 is in a retracted state, the carriage 2 is located on the automobile chassis 1, and then the cylinder legs 5 are extended to support on the ground, the lifting cylinder 34 is actuated, driving the carriage 2 to rotate with the hinge at the middle and upper part of the rear end as the rotating axis, the lifting cylinder 34 drives the carriage 2 to lift and flip upward, and the loading port of the carriage 2 is turned to the rear of the self-loading and unloading system 3 to dump the garbage, and then the reverse action is performed, and the carriage 2 falls back onto the automobile chassis 1 as the lifting cylinder 34 is reset.
