[0002] Kitchen waste is an important part of urban waste. At present, in order to comply with environmental protection and recycling requirements, most of the kitchen waste in urban life is broken down into small pieces in waste treatment equipment, and then converted into organic matter or feed through fermentation so that it can be recycled.

[0003] At present, a Chinese patent with authorization announcement number CN215918604U discloses a feeding system in a garbage treatment equipment, including a feeding device, a biochemical bin, and a solid-liquid separation device. The feeding device includes a feeding base, and the feeding base is provided with a feed port 1 and a discharge port 1. The solid-liquid separation device is provided with a feed port 2, and the feed port 2 is connected to the discharge port 1. The output end of the solid-liquid separation device is connected to the biochemical bin. The feeding base is also provided with a switching device and a discharge port 2. The discharge port 1 and the discharge port 2 can be connected to the feed port 1 respectively. The switching device can control the material to be discharged from the discharge port 1 or the discharge port 2. The biochemical bin has a feed port 3, and the feed port 3 is connected to the discharge port 2. The material can be directly discharged from the discharge port 2 and enter the biochemical bin through the feed port 3 for fermentation, avoiding unnecessary steps and effectively saving energy.

[0004] Among them, the solid-liquid separation device includes a feeding barrel and a feeding screw. The feeding screw is rotatably arranged inside the feeding barrel, the second feed port is arranged at one end of the feeding barrel, and the other end of the feeding barrel is provided with an outlet port three. The side wall of the feeding barrel is provided with a water filter hole, and the outside of the feeding barrel is provided with a baffle for blocking the outlet port three. The material can break through the baffle, and the outside of the baffle is provided with a resetting device that can reset the baffle. The material enters from the feed port two, and through the rotation of the feeding screw, the material is transferred from the feed port two to the outlet port three.

[0005] The reset device includes a reset spring and a fixed plate. The fixed plate is fixed to the outside of the reset spring. One end of the reset spring abuts against the fixed plate, and the other end of the reset spring abuts against the baffle. Since the reset spring is exposed to the outside, it is easily corroded and damaged by direct contact with the acidic substances in the material. Utility Model Content

[0016] To implement the above technical solution, when the guide tube slides along the length direction of the spiral rod, the moisture on the spiral rod is blocked by the sealing ring and is not easy to enter the installation hole, thereby further extending the service life of the elastic member.

[0017] As a preferred solution of the utility model, the discharge box is connected to a power rod through a driving mechanism, the power rod is rotatably connected to the discharge box, a spiral plate is fixedly connected to the outer wall of the power rod, and the length direction of the power rod is parallel to the length direction of the discharge box.

[0018] To implement the above technical solution, after the driving mechanism is started, the power rod rotates and the spiral plate rotates, so that the dried material is discharged from the discharge port under the drive of the spiral plate.
