The mechanical earthworm collecting device comprises a chassis, a walking system, a mounting frame, a screening mechanism, a conveying mechanism and a cleaning mechanism, a power supply system and a control system are mounted on the chassis; the walking system is mounted at the bottom of the chassis; the mounting rack is mounted on the chassis; the screening mechanism comprises a driving assembly, a discharging groove, a collecting box and a screening barrel. The screening barrel is rotationally connected to the mounting frame, a plurality of screening holes are formed in the screening barrel, and the driving assembly and the discharging groove are both mounted on the mounting frame; the cleaning mechanism comprises a liquid storage assembly and a spraying assembly; the liquid storage assembly is installed on the upper portion of the chassis, the top of the liquid storage assembly is open, and the spraying assembly is installed on the installation frame. The other end of the spraying assembly is located on the outlet side of the inner cavity of the screening barrel. The liquid storage assembly is located under the spraying assembly. The earthworm collecting device can be used for separating and cleaning earthworms and breeding materials in the earthworm breeding bed and collecting finished earthworms, so that the collecting efficiency is effectively improved, and the labor cost for collecting the earthworms is saved.

This utility model provides an automatic continuous feeding mechanism for a cooking machine, comprising: a base plate; a moving platform mounted on the base plate; a discharge through-hole on the moving platform; a feeding slide disposed on the moving platform; a hopper disposed on the moving platform; a discharge outlet on the hopper; a bottom opening on the hopper; a hopper-connecting drive component; a position sensor for sensing the position of the hopper; multiple material box assemblies placed in the hopper from top to bottom; each material box assembly includes a box body plate, multiple box bodies, and a sealing film; a film-tearing mechanism disposed on the discharge outlet of the hopper, the film-tearing mechanism including a film-tearing shaft, a film-tearing hook disposed on the film-tearing shaft, and a shaft drive component connected to the film-tearing shaft; a lifting device that can enter the hopper through the bottom opening; and a lifting device including a support block and a block drive mechanism connected to the support block. This automatic continuous feeding mechanism for the cooking machine eliminates the need for manual filling and cleaning, enables automatic film removal and feeding, and allows for continuous automatic feeding of multiple stations and multiple dishes.

This utility model provides a noise reduction structure for an air conditioning ventilation system, belonging to the field of air conditioning system noise reduction technology. It includes a ventilation duct with sound-insulating cotton installed inside, and a filter assembly at the front end of the ventilation duct. The filter assembly includes a fixed frame, which is fixedly installed inside the ventilation duct. The sound-insulating cotton effectively isolates noise from inside the ventilation duct, achieving noise reduction. With the positioning component, when the filter screen has little dust and needs cleaning, the filter screen, movable frame, and fixed frame can be easily rotated out. At this time, the filter screen is not detached from the ventilation duct, allowing workers to clean it directly without disassembly, making operation convenient. With the limiting component, when deep cleaning of the filter screen is required, it can be directly removed from inside the movable frame for deep cleaning, also making operation convenient.

The utility model discloses a disposable waste liquid bag device capable of being connected in multiple modes. The disposable waste liquid bag device comprises a negative pressure source and at least two liquid storage bottles. Liquid storage bags are arranged in the liquid storage bottles, the negative pressure source is communicated with the liquid storage bags and cavities between the liquid storage bags and the liquid storage bottles through pipelines, and anti-overflow valves are arranged on the pipelines between the negative pressure source and the liquid storage bags and used for preventing liquid in the liquid storage bags from flowing into the negative pressure source. Wherein one liquid storage bag is respectively connected with a user through a pipeline and is sequentially communicated with the interiors of the other liquid storage bags in series one by one, the automatic circulation of waste liquid in the plurality of liquid storage bottles can be realized through the plurality of liquid storage bags which are communicated in series and are all arranged in the liquid storage bottles, and when the waste liquid reaches a certain amount, the automatic circulation of the waste liquid in the plurality of liquid storage bottles can be realized. And the liquid storage bottle can be discarded without cleaning, so that the working efficiency is improved.
