Description

Rotary spreading device with automatic diameter adjustment

technical field

The invention relates to the technical field of winery automatic steamer loading machinery, in particular to a rotary spreading device with automatic diameter adjustment.

Background technique

At present, the sprinkler head of the automatic retort system in the winery moves in the X and Y directions to form a circular motion, or the swing combination of the two feeding devices forms a circular motion, and the conversion of the spreading speed and the spreading diameter is slow. Secondly, the feeder in the device has to move to a fixed point to pick up the material after the spreading head has finished spreading for a week, and the auxiliary time for picking up the material is too long. The inventors have found through research that both of the above two situations will cause the steam to overflow the sprinkler and it will be too late to feed the material, which will affect the wine production efficiency and wine quality. Therefore, it is necessary to design a rotary spreading head with continuous feeding and automatic diameter adjustment to realize rapid and uniform spreading.
