On both sides of the lifting compression plate 14, sliding grooves one 15 that cooperate with the lifting slide columns 11 are opened. On both sides at the rear of the lifting compression plate 14, sliding grooves two 16 that cooperate with the pulley grooves 13 are opened. By providing the sliding grooves one 15 and the sliding grooves two 16 to be slidably mated with the lifting slide columns 11 and the pulley grooves 13, the lifting compression plate 14 can be lifted and slid in the barrel body 5. In the middle at the rear of the barrel body 5, a lifting groove 17 is opened. At the rear of the lifting compression plate 14, a hydraulic cylinder connecting plate 18 is fixedly arranged. The hydraulic cylinder connecting plate 18 is arranged in the lifting groove 17 and is slidably connected thereto. At the lower part at the rear of the barrel body 5, a hydraulic cylinder support plate 19 is fixedly arranged. On the upper part of the hydraulic cylinder support plate 19, a hydraulic cylinder 20 is fixedly arranged.

At the rear of the barrel body 5, a hydraulic cylinder protection shell 21 is fixedly arranged to protect the hydraulic cylinder 20.

[0027] At the rear lower side of the lifting compression plate 14, a folding plate seat one 22 is fixedly arranged. At the lower part of the lifting compression plate 14, a plurality of folding plates are arranged and are rotatably connected thereto through the folding plate seat one 22. The folding plate includes a plate body 23. On both sides at the rear of the plate body 23, folding plate rotating shafts 24 are fixedly arranged. On both sides at the front of the plate body 23, folding plate rotating shaft seats 25 are fixedly arranged. The folding plate is arranged in the folding plate seat one 22 through the folding plate rotating shaft 24 and is rotatably connected thereto by arranging a rotating shaft rod 26 in the folding plate seat one 22.

By providing a plurality of folding plates that are connected end to end and can be folded, during the lifting process of the lifting compression plate 14, they are folded in cooperation therewith to further compress the internal space of the barrel body 5.

[0028] On both sides of the rear part of several of the plate bodies 23, pulley rotating seats 28 are fixedly provided. An expansion tube 29 is arranged inside the pulley rotating seat 28 and is rotatably connected thereto. Expansion sliding grooves 30 are formed on both sides of the expansion tube 29. Slide columns 31 are arranged inside the two expansion sliding grooves 30 and are slidably connected thereto. An expansion column 32 is fixedly arranged between the two slide columns 31 and is slidably connected to the expansion tube 29. The expansion column 32 slides in the expansion sliding groove 30 through the slide columns 31 arranged on both sides and is limited by them to prevent it from falling off.

By arranging the expansion column 32 and the expansion tube 29 and arranging the pulleys 34 that can cooperate with the pulley groove 13 on both sides of the end of the expansion column, several of the plate bodies 23 can be connected to the pulley groove 13, which is used to maintain the shape of each folding plate during the folding process, so that each folding plate can be folded against the rear part of the barrel body 5 to prevent deformation and occupation of the internal space of the barrel body 5.

[0029] On both sides of the front part of the lower side of the lifting and compressing plate 14, spring shaft seats 35 are fixedly provided. A spring shaft 36 is arranged inside the spring shaft seat 35 and is rotatably connected thereto. Flap plates 37 are fixedly arranged at the front parts of the two spring shafts 36. The spring shaft seat 35 gives the flap plates 37 a force to rotate upward, so that the user can press down the flap plates 37 and put garbage into the barrel body 5, and can drive the flap plates 37 to compress the internal garbage during the process of the lifting and compressing plate 14 descending for compression. Since it can only turn downward, it can remain stationary during the compression process to compress the internal garbage.

[0030] A handle 38 is fixedly provided at the upper part of the rear side of the barrel body 5, which is used to facilitate the lifting and turning of the barrel body 5 by personnel.

[0031] This solution also includes a controller, the position of which is set according to the actual situation by the staff during operation. The controller is used to control all the electrical appliances in this solution, including but not limited to sensors, motors, telescopic rods, water pumps, solenoid valves, heating wires, heat pumps, display screens, computer input devices, switch buttons, communication devices, lights, speakers and microphones. The controller is an Intel processor, AMD processor, PLC controller, ARM processor or single-chip microcomputer, and the motherboard, memory, storage medium and power supply are also used in supporting. The power supply is mains electricity or a lithium battery. When there is a display screen, a display card is also provided. For the operating principle of the controller, please refer to "Principles of Automatic Control", "Principles and Application Simulation Cases of Microcontrollers" and "Principles and Applications of Sensors" published by Tsinghua University Press. Other books in this field can also be referred to for reading. Other automated controls and electrical appliances not mentioned are all well-known knowledge to those skilled in the art and will not be elaborated here.

[0032] Operating principle:

[0033] When the device is in use, personnel open the flap 37 by pushing it downward to put garbage and the like into the barrel body 5 for collection. Subsequently, the flap 37 is lifted by the spring shaft seat 35 and the spring shaft 36. After the garbage inside the barrel body 5 accumulates to a certain extent, the hydraulic cylinder 20 drives the lifting compression plate 14 to slide downward. Further, the lifting compression plate 14 drives the flap 37 to descend to compress the garbage inside the barrel body 5. Since the flap 37 can only be turned downward, the compression process can keep it stationary to compress the internal garbage. Further, the lifting compression plate 14 drives several folding plates installed at the lower part. The folding plates are connected end to end through the plate body 23 included therein and the folding plate rotating shafts 24 and folding plate rotating shaft seats 25 provided on both sides, and are driven by the lifting compression plate 14 to fold, further compressing the garbage inside the barrel body 5, so that more garbage can be put into the barrel body 5 to improve the space utilization efficiency. Further, several rotatable telescopic columns 32 and telescopic tubes 29 are arranged at the rear of the plate body 23, and pulleys 34 that can cooperate with the pulley grooves 13 are arranged on both sides of the end of the telescopic column, so that several plate bodies 23 can be connected to the pulley grooves 13 to maintain the shape of each folding plate during the folding process, so that each folding plate can be folded against the rear part of the barrel body 5 to prevent deformation from occupying the internal space of the barrel body 5. After compression, the hydraulic cylinder 20 pushes the lifting compression plate 14 to rise, allowing personnel to continue putting garbage into the barrel body 5. After the barrel body 5 is full of garbage, the barrel body 5 is pulled up by the handle 38 and the rotating shaft columns 4 on both sides thereof are moved to one end of the moving groove 3. Further, the barrel body 5 is driven to flip by the handle 38. The bottom cover 8 is opened by opening the latch 9, so that the garbage inside the barrel body 5 is discharged to the collection tool through the cooperation of the bottom and the compression device for collection. After completion, the barrel body 5 is returned to its original position to complete the collection work, and the collection of garbage and the compression work can continue. The structure of this device is simple, which can improve the internal space utilization rate of the trash can, reduce the frequency of personnel transporting garbage, and is suitable for popularization and use.
