Description

technical field [0001] The invention relates to a walnut processing machine, in particular a walnut cleaning machine. Background technique [0002] China is a big producer of walnuts. The traditional harvesting method is to wait until the walnuts are ripe, lay them down from the tree and pile them up for a few days, then manually peel the walnuts to remove the green skin. The existing manual walnut peeling is labor-intensive, the juice in the walnut skin pollutes the human body and is difficult to remove, and the working environment is harsh. Since the peeled walnuts are also mixed with green skins, the peeled walnuts also need to be cleaned. Existing cleaning equipment is cleaned manually or by simple machines. Due to the high labor intensity and harsh environment, it is not conducive to mass production. [0003] At present, most of the walnut cleaning machines at home and abroad adopt the cleaning method of brush roller. The head and tail of the commonly used brush rolle...

AI Technical Summary

Problems solved by technology

[0004] There are many problems in the above installation method: the bearing seats at the front and rear ends are all floating, and the fastening bolts are loose during transportation and use, which is particularly easy to shift the brush rollers, causing adjacent brush rollers to touch together, and the motor current increases. large, even overloaded and burned

The installation and debugging are quite cumbersome, and the main shaft often comes into contact with the lower side of the hole on the wallboard, which consumes extra power
