[0029] Turn on the first motor 14 and put solid agricultural waste such as feces to be fermented into the feed hopper 2. During the feeding process, the first motor 14 drives the runner 13 to rotate, thereby driving the rotating arm 12 to move, and further driving the connecting rod 10 together with the sliding crushing frame 7 to perform left and right reciprocating movements through the chute 6, so that the pointed crushing knives 8 and side crushing knives 9 on the sliding crushing frame 7 can cooperate with the pointed crushing knives 8 and side crushing knives 9 on the fixed crushing frame 5 to crush the materials entering the inside of the crushing chamber 4, playing a role in increasing the surface area of the waste, facilitating air permeability, accelerating decomposition, and thus facilitating subsequent fermentation.
[0030] Air is supplied to the hollow stirring shaft 16 through a blower 21 via an air supply pipe 20 and a rotary joint 19, so that external air is input into the inside of the crushing and fermentation bin 1 through the ventilation holes 18 on the hollow stirring rods 17, playing a role in promoting the contact between oxygen and organic waste, enhancing the activity of aerobic bacteria in the waste, and thus enhancing the fermentation efficiency.
