[0020] 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.

[0021] Please see Figure 1-5 This utility model provides a technical solution:

[0022] A garbage compression and lifting transfer station is used to compress garbage and load it into a garbage truck 1. It includes a pit 2, a first-level transfer station 3 built on the pit 2, a second-level transfer station 4 built on the first-level transfer station 3, and a passageway 11 connecting the first-level transfer station 3 and the second-level transfer station 4. A hopper 7 is placed inside the pit 2, with notches 14 on both opposite sides of the hopper 7. A compression assembly is installed inside the pit 2. A connecting arm 13 is fixedly installed on the top of the hopper 7. A chain elevator 6 is fixedly installed on the side walls of the second-level transfer station 4 and the first-level transfer station 3. The connecting arm 13 is connected to the lifting end of the chain elevator 6. A discharge port 5 is fixedly connected to the bottom of the second-level transfer station 4, located above the garbage truck 1. The width of the hopper 7 is the same as the width of the passageway 11, but the width of the hopper 7 is less than the width of the pit 2.

[0023] Please see Figure 1 and Figure 2 The garbage truck 1 reverses and drives into the first floor 3 of the transfer station. Then, it flips its container so that the garbage inside can be poured into the hopper 7 in the pit 2. At this time, some of the liquid in the garbage can flow from the hopper 7 into the pit 2. Then, the garbage truck 1 resets its container and drives to the second floor 4 of the transfer station, below the discharge port 5. At this time, the compression component inside the pit 2 can compress the garbage in the hopper 7. Some of the liquid produced during the compression process can flow back into the pit 2. After compression, the chain elevator 6 lifts the hopper 7 and the compressed garbage inside the hopper 7 through the connecting arm 13 until the hopper 7 is lifted into the second floor 4 of the transfer station. Then, the staff inside the second floor 4 of the transfer station can transfer the compressed garbage to the garbage truck 1 through the discharge port 5.

[0024] It should be noted that, in order to further separate the compressed waste and sewage, through holes or drainage channels can be opened on the bottom wall of the hopper 7 in this embodiment, so that solid-liquid separation can be achieved under the action of gravity. In addition, in order to prevent sewage from causing corrosion in the pit 2 for a long time, this embodiment installs the corresponding cleaning system and sewage system in the prior art inside the pit 2, thereby achieving cleaning of the pit 2.

[0025] It should be known that, in order to facilitate the entry and exit of staff in the second floor 4 of the transfer station, this embodiment should install stairs on the second floor 4 of the transfer station and on the ground, and open doors on the side walls of the second floor 4 of the transfer station to facilitate the entry and exit of staff.

[0026] The compression assembly includes a pair of hydraulic cylinders 8 and a pair of compression molds 9. The pair of hydraulic cylinders 8 are symmetrically and horizontally fixedly installed on two opposite inner walls of the pit 2. The two compression molds 9 are respectively fixedly connected to the output ends of the two hydraulic cylinders 8. The two compression molds 9 are horizontally slidably connected inside the hopper 7 through two notches 14.

[0027] Please see Figure 1 and Figure 3 In this embodiment, two hydraulic cylinders 8 are activated simultaneously. The two hydraulic cylinders 8 can drive a compression mold 9 to move from two opposite notches 14 on the hopper 7. Since the two compression molds 9 move at roughly the same horizontal speed, the garbage inside the hopper 7 can be compressed inside the hopper 7. When the two compression molds 9 come into contact, the hydraulic cylinders 8 are stopped. At this time, the two compression molds 9 and the inside of the hopper 7 form a rectangular cavity, which can compress the garbage into the shape of the cavity.

[0028] It should be noted that it is common knowledge to those skilled in the art that the two hydraulic cylinders 8 are controlled to extend and retract at the same speed by the controller, and the specific working principle and control process will not be described in detail here.

[0029] A limiting seat 15 is fixedly installed on the side wall of the hopper 7. A guide rail 10 is vertically fixedly installed on the side wall of the second floor 4 of the transfer station. The bottom end of the guide rail 10 extends through the first floor 3 of the transfer station to the inside of the pit 2. The limiting seat 15 is slidably connected to the guide rail 10. A groove 16 is provided on the limiting seat 15. A roller 17 is rotatably connected to the inner wall of the groove 16. The limiting seat 15 is slidably connected to the guide rail 10 through the groove 16. The surface of the roller 17 abuts against the surface of the guide rail 10.

[0030] Please see Figure 1 , Figure 4 and Figure 5During the process of lifting the bucket 7 by the chain elevator 6, the bucket 7 can drive the limiting seat 15 to slide on the surface of the guide rail 10. Through the cooperation of the limiting seat 15 and the guide rail 10, the vertical movement of the bucket 7 can be limited, thereby preventing the bucket 7 from shaking during movement. When the limiting seat 15 moves, it can drive the roller 17 to move synchronously through the groove 16, thereby causing the roller 17 to move relative to the guide rail 10. At this time, sliding friction can be generated between the roller 17 and the guide rail 10, thereby limiting the vertical movement of the bucket 7 while reducing the friction between the bucket 7 and the guide rail 10.

[0031] A deodorizing ventilation fan 12 is fixedly installed on the outer wall of the second floor 4 of the transfer station. The first floor 3 and the second floor 4 of the transfer station are connected to the outside through the deodorizing ventilation fan 12.

[0032] Please see Figure 1 In this embodiment, the air inside the first floor 3 and the second floor 4 of the transfer station exchanges gas with the outside through the deodorizing ventilation fan 12. The air inside the first floor 3 and the second floor 4 of the transfer station can be deodorized by the deodorizing ventilation fan 12 before being discharged to prevent interference with the nearby air environment.

[0033] 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.
