A person of ordinary skill in the art may understand specific meanings of the foregoing terms in this application according to specific situations Referring to FIG. 1 to FIG. 3, the following describes an automatic overturning device 100 for a garbage can according to an embodiment of this application As shown in FIG. 1, the automatic overturning device 100 for a garbage can in this embodiment of this application includes a base 1, at least two groups of connecting rod mechanisms 4, at least two groups of push rod mechanisms 5, and a driving mechanism 2. One end of the connecting rod mechanism 4 is rotatably connected to the base 1, and the other end of the connecting rod mechanism 4 is rotatably connected to a garbage can 200. The driving mechanism 2 includes a driving electric motor 21 and a transmission assembly 22, which are mounted on the base 1, the driving electric motor 21 is in synchronous transmission connection with the at least two groups of push rod mechanisms 5 by means of the transmission assembly 22, and one end of each of the push rod mechanisms 5 is rotatably connected to each of the connecting rod mechanisms 4.

It may be understood that, the base 1 serves as a basis for the automatic overturning device 100 for a garbage can, components such as the driving electric motor 21 and the transmission assembly 22 are disposed on the base 1, and operating stability of the automatic overturning device 100 for a garbage can may be improved.

In a general trash dumping apparatus, a traditional cylinder is mostly used as a drive, for example, a garbage can hydraulic rod is embedded in the apparatus, the garbage can hydraulic rod is mounted at the bottom of the garbage can, and trash dumping is completed through a garbage can dumping shaft. This manner has problems of a large overall size and easy oil leakage from an oil pipeline.

As shown in FIG. 1, in the automatic overturning device 100 for a garbage can in this embodiment of this application, the driving electric motor 21 is applied to provide power for the transmission assembly 22, and the transmission assembly 22 is enabled to transmit power to the connecting rod mechanism 4. This mechanical transmission manner has long service life and zero pollution, and can also resolve the problem of oil leakage.

In some trash dumping devices, two hydraulic cylinders are applied to perform trash dumping. However, it is difficult to ensure synchronicity between the two cylinders, and there is still the problem of high costs in the hydraulic cylinders.

In the automatic overturning device 100 for a garbage can in this embodiment of this application, as shown in FIG. 1 to FIG. 3, the driving electric motor 21 is in synchronous transmission connection with the at least two groups of push rod mechanisms 5 by means of the transmission assembly 22. The at least two groups of push rod mechanisms 5 may separately transmit power to the at least two groups of connecting rod mechanisms 4, to enable the at least two groups of connecting rod mechanisms 4 to be deformed, and to implement lifting of the garbage can 200 in a deformation process, so as to facilitate turning-over of the garbage can 200 and trash dumping. In this way, not only the entire automatic overturning device 100 occupies a small area, but also the automatic overturning device 100 for a garbage can is applicable to a device of a relatively small size, increasing an applicable range of the automatic overturning device 100 for a garbage can. In addition, the apparatus has good synchronicity, to avoid a case that the garbage can cannot accurately return to an initial mounting position due to the unsynchronized push rod mechanism 5. In addition, the apparatus can simplify control, reduce costs, and enable force to be more balanced and stable, improving stability and reliability of the automatic overturning device 100 for a garbage can in an operating process.

In the automatic overturning device 100 for a garbage can in this embodiment of this application, the transmission assembly 22 that can be synchronously driven is provided between the driving electric motor 21 and the push rod mechanism 5, so that the entire automatic overturning device 100 is enabled to occupy a small area and has good synchronicity, to avoid a case that the garbage can 200 cannot accurately return to an initial mounting position due to the unsynchronized push rod mechanism 5. The transmission assembly 22 sequentially and synchronously transmits power to the at least two groups of push rod mechanisms 5 and the at least two groups of connecting rod mechanisms 4, to implement rising and lowering of the garbage can 200, so as to facilitate turning-over of the garbage can 200 and trash dumping. Therefore, this not only resolves the problem of easy oil leakage from an oil pipeline in the conventional cylinder, to enable a force of the automatic overturning device 100 to be more balanced and stable, but also reduces costs, so that the automatic overturning device 100 for the garbage can is applicable to devices of different types, to increase an applicable range of the automatic overturning device 100 for the garbage can.

In some embodiments, as shown in FIG. 1, the push rod mechanism 5 includes a sliding rail 51, a rack 52, and a push rod 53. The sliding rail 51 is mounted on the base 1, the rack 52 is slidably connected to the sliding rail 51, a power output gear 222 of the transmission assembly 22 is connected to the rack 52 in a transmission way, one end of the push rod 53 is rotatably connected to the rack 52, and the other end of the push rod 53 is rotatably connected to each of the connecting rod mechanisms 4. It may be understood that, the power output gear 222 may transmit power to the rack 52, enable the rack 52 to slide relative to the sliding rail 51, and drive the push rod 53 to move and rotate. In this way, in a motion process of the push rod 53, the connecting rod mechanism 4 is enabled to be deformed. The meshing transmission form of the gear and the rack 52 is applied herein, the structure is simple, and the transmission is stable, helping improve operating reliability of the push rod mechanism 5.

Specifically, as shown in FIG. 1, the transmission assembly 22 includes a first transmission shaft 224 and a second transmission shaft 225, which are mounted on the base 1 in parallel, power output gears 222 that are mounted on both ends of the first transmission shaft 224, a power input gear 221 that is mounted at the middle of the second transmission shaft 225, and intermediate transmission gears 223 that are mounted on both ends of the second transmission shaft 225. Each of the intermediate transmission gears 223 meshes with the corresponding one of the power output gears 222. It may be understood that, the driving electric motor 21 drives the power input gear to rotate, so as to enable the second transmission shaft 225 and the intermediate transmission gear 223 to rotate synchronously, and the rotated intermediate transmission gear 223 may transmit power to the power output gear 222. The gear meshing transmission form herein has advantages such as high working stability, high transmission efficiency, and compact structure, helping improve transmission efficiency and working stability of the transmission assembly 22.

Optionally, one end of the push rod 53 is rotatably connected to the rack 52 by using a mounting pin. Therefore, this may implement reliable transmission.

Therefore, connection reliability of the sliding block 54 can be improved, and sliding operating of the rack 52 can be facilitated.

In some optional embodiments, the transmission assembly 22 includes a first transmission shaft 224 that is mounted on the base 1 and a sprocket that is mounted at the middle part of the first transmission shaft 224, the driving electric motor 21 is connected to the sprocket by using a chain, and one power output gear 222 is mounted on both ends of the first transmission shaft 224. It may be understood that the driving electric motor 21 may drive the chain to rotate so that the sprocket, the first transmission shaft 224, and the power output gear 222 rotate synchronously, and thus transmit power to the rack 52. A form of cooperation between the chain and the sprocket herein is used to implement long-distance transmission, and ensures working in environments such as low speed, heavy load, and dust rising, helping increase an applicable range of the transmission assembly 22.

Optionally, the push rod mechanism 5 may include a sliding rail Si, a screw, a nut, and a push rod 53. The bottom of the nut may be slidably connected to the sliding rail 51, the power output gear 222 is a bevel gear, the bevel gear is overlapped with a rotation axis of the screw, one end of the push rod 53 is rotatably connected to the nut, and the other end of the push rod 53 is rotatably connected to each of the connecting rod mechanisms 4. In this way, the bevel gear and the screw can rotate synchronously, so that the bottom of the nut is enabled to reciprocate on the base 1. A form of cooperation between the screw and the nut herein is used, and motion precision is high, for example, a movement distance of the rack 52 can be accurately controlled by using a quantity of rotation circles of the screw, improving operating precision of the automatic overturning device 100 for a garbage can. A specific form of cooperation between the transmission assembly 22 and the push rod 53 is not limited herein.

In some embodiments, as shown in FIG. 1, the connecting rod mechanism 4 includes a first connecting rod 41 and a second connecting rod 42. One end of the first connecting rod 41 is hinged to the base 1, and the other end of the first connecting rod 41 is configured to be hinged to a garbage can 200. One end of the second connecting rod 42 is hinged to the base 1, and the other end of the second connecting rod 42 is configured to be hinged to the garbage can 200.

It may be understood that, in some trash dumping apparatuses, a turning-over mechanism and a lift mechanism are separately disposed. For example, a four-stage telescopic hydraulic cylinder on a mechanical arm enables, by using a hierarchical telescopic feature, the mechanical arm to clamp the garbage can to lift and lower, and the turning-over mechanism is as follows: When the clamped garbage can reaches a specified position, a stepper motor drives the mechanical arm to clamp the garbage can to perform turning-over. However, the entire set of apparatus is expensive, and there is a problem of oil leakage from an oil pipeline. For another example, a portal frame is provided with a rising and lowering apparatus for a garbage can and an automatic overturning device for dumping of a garbage can, and a turning-over cylinder is connected, by using a transmission arm, to a turning-over an to complete trash dumping. However, there are problems of a large overall size in the apparatus and oil leakage from an oil pipeline.

In the automatic overturning device 100 for a garbage can in this embodiment of this application, the push rod mechanism 5 may transmit power to the first connecting rod 41. In this way, when the first connecting rod 41 rotates, the garbage can 200 and the second connecting rod 42 are enabled to sequentially rotate, implementing rising and lowering of the garbage can 200, and simultaneously driving the garbage can 200 to turn over.

Specifically, the first connecting rod is provided with a first hinge point 414 that is configured to hinge the garbage can 200, and the second connecting rod is provided with a second hinge point 421 that is configured to hinge the garbage can 200. In this way, when the driving electric motor 21 rotates, the driving electric motor 21 can transmit power to the push rod mechanism 5 by means of the transmission assembly 22, to drive the connecting rod mechanism 4 to be deformed, so that both heights and relative positions of the first hinge point 414 and the second hinge point 421 change, driving the garbage can 200 to rise and lower, and simultaneously driving the garbage can 200 to turn over.

It should be noted that the connecting rod mechanism 4 including the first connecting rod 41 and the second connecting rod 42 is disposed between the garbage can 200 and the base 1, and the first connecting rod 41, and the garbage can 200, the second connecting rod 42, and the base 1 are enabled to form a four-connecting rod structure, to help improve transmission stability and reliability. In addition, the second connecting rod 42 may also play a role in preventing a case that swing generated along a length direction of the garbage can 200 causes that the garbage can 200 cannot return.

Further, as shown in FIG. 1, the first connecting rod 41 includes a first arm 411, a second arm 412, and a plurality of connection parts 413 that are disposed between the first arm 411 and the second arm 412. The plurality of connection parts 413 are disposed at evenly intervals along a length direction of the first arm 411, and the one end of each of the push rod mechanisms 5 is rotatably connected to one of the connection parts 413. It may be understood that the first arm 411 and the second arm 412 are disposed to improve structural strength of the first connecting rod 41, helping increase service life of the first connecting rod 41. The plurality of connection parts 413 may be disposed to connect the first arm 411 and the second arm 412, to improve connection reliability and motion synchronicity between the first arm 411 and the second arm 412, to provide a mounting position for the push rod mechanism 5, and to help facilitate flexible layout of the automatic overturning device 100 for a garbage can. For example, the push rod mechanism 5 can be selectively connected to the connection parts 413 in different positions according to the actual situation. If the garbage can 200 needs to have a higher raising or lowering height, the push rod mechanism 5 may be selectively connected to a connection part 413 away from the garbage can 200. If the rising or lowering height of the garbage can 200 needs to be reduced, the push rod mechanism 5 may be selectively connected to a connection part 413 of the garbage can 200. A specific connection position of the push rod mechanism 5 is not limited herein.

Optionally, the connection part 413 may be a shaft part, or may be a sleeve part, and a form of the connection part is not specifically limited herein In some optional embodiments, as shown in FIG. 1, the sliding rail 51 is gradually tilted upward in a direction toward the base 1. It may be understood that the sliding rail 51 may be disposed to guide the sliding of the rack 52, to improve movement precision of the rack 52 and reduce motion offset. The sliding rail 51 herein is gradually tilted upward in a direction toward the garbage can 200. Not only the rising or lowering height of the garbage can 200 is increased, but also the layout of the automatic overturning device 100 for a garbage can is more compact, helping the automatic overturning device 100 to be miniaturized.

Optionally, the base 1 is further provided with a sliding rail mounting seat 14, and the sliding rail 51 is connected to the base 1 by using the sliding rail mounting scat 14. Therefore, connection stability and reliability of the sliding rail 51 can be improved.
