Further optimize this technical scheme, the bars post sets up with worm portion one-to-one.
Further optimize this technical scheme, be provided with the bearing seal device between motor output shaft and the transmission case.
Further optimizing the technical scheme, a shaft seal device is arranged between the grid column and the transmission case.
Further optimize this technical scheme, the bars post is connected with transmission case pivot.
Further optimize this technical scheme, the driving shaft is kept away from motor one end and is connected with the transmission case pivot.
Compared with the prior art, the utility model has the advantages of it is following: 1. the structure is beneficial to ensuring that when dirt is attached to the surface of the grid column, the grid column can be driven to rotate by the action of the motor, and the dirt is washed away by water flow, so that the effect of ensuring the overflowing capacity of the trash rack is achieved, and the driving shaft and the worm wheel are arranged in the transmission box and are not easy to contact with water; 2. one section of the outer edge of the trash holding part is in the shape of an Archimedes spiral line, and the structure is favorable for ensuring that the plurality of grid columns are driven to rotate simultaneously, so that the distance between the grid columns can be freely adjusted according to different use conditions.
