[0020] By adopting the above technical solution, the driving member drives the connecting rod to slide, the connecting rod drives the scraper rod to slide, and the scraper rod scrapes and cleans the two side walls of the partition to reduce the adhesion of materials on the partition.

[0021] Optionally, the driving member includes a driving motor and a pushing rod, the driving motor is arranged on the outer side wall of the connecting tube, the pushing rod is slidably installed on one side of the connecting tube and connected to the connecting rod, and the pushing rod is connected to the output shaft of the driving motor through a connecting rod.
