Specifically, during the welding process of the stirring blade and the main shaft 21, a larger welding area is formed between the first plate body 221 and the main shaft 21 due to the larger thickness of the first plate body 221. In this way, after the first plate 221 and the main shaft 21 are welded together, more solder can be filled in the welding area formed between the first plate 221 and the main shaft 21, so that the first plate 221 and the main shaft 21 are welded more firmly and reliably.

Since the thickness of the first plate body 221 is thick and the first plate body 221 is arranged upright, the weld between the first plate body 221 and the main shaft 21 will be substantially parallel to the axis of the main shaft 21, which makes it easier for the operator to handle when welding. In the case of the second plate 222 and the third plate 223, the second plate 222 and the third plate 223 are welded to the edge of the first plate 221 and the spindle 21. Taking the second plate 222 as an example, a welding area is formed between the edge of the second plate 222 and the edge of the first plate 221, and the edge of the second plate 222 is fixed on the first plate 221 by welding; meanwhile, a welding area is formed between the end of the second plate 222 and the main shaft 21, and the end of the second plate 222 is welded and fixed to the main shaft 21 by welding.

In addition, since the first plate 221 is vertically arranged, the bearing capacity of the first plate 221 is greatly improved in the height direction, and the bending resistance of the first plate 221 is further improved, so that the bending resistance of the stirring blade is integrally improved.

In this way, after the length of the stirring blade is increased according to the stirring requirement, the deformation amount of the stirring blade along the length direction is small, so that the use reliability of the stirring blade is further improved.

In order to improve the connection strength among the three plate bodies when the mixing blade is assembled, a plurality of reinforcing plates 224 may be further provided among the first plate body 221, the second plate body 222, and the third plate body 223, and the plurality of reinforcing plates 224 may be arranged along the longitudinal direction of the mixing blade.

Specifically, a space with a cross section similar to a triangle is formed among the first plate 221, the second plate 222 and the third plate 223, and a plurality of reinforcing plates 224 are arranged in the triangular space along the length direction of the stirring blade, so that the reinforcing plates 224 increase the structural strength and the connection strength among the three plates. In actual assembly, the reinforcing plate 224 may be welded between the first plate 221 and the second plate 222, and then the third plate 223 may be welded; alternatively, the reinforcing plate 224 is welded between the first plate body 221 and the third plate body 223, and then the second plate body 222 is welded.

Since the gas transmission channel 225 is externally arranged on the outer part of the stirring blade, the gas flow section of the external gas transmission channel 225 is smaller, so that the gas flow velocity is higher, and finally the vent hole 220 outputs high-velocity gas flow to supply gas to the organic waste in the fermenting chamber 1.

There are various ways to specify the configuration of the gas delivery channel 225.

For example: an air duct cover 226 is disposed on an outer surface of the first plate 221, an air transmission channel 225 is formed between the air duct cover 226 and the first plate 221, and an air vent 220 is disposed on the air duct cover 226. Specifically, the duct cover 226 has an L-shaped or semicircular cross section, and the duct cover 226 is welded to the outer surface of the first plate 221 so as to form the air transmission channel 225 therebetween.

And for the air supply mode of the bottom air outlet 11, the air can be supplied more comprehensively and effectively at the bottommost layer of the organic waste so as to ensure that the air supply at the bottommost layer of the fermentation chamber 1 is uniformly distributed.

In a preferred embodiment, the outer surface of the first plate 221 is provided with a shielding plate 227, and the shielding plate 227 is disposed above the vent hole. Specifically, in the using process, the shielding plate 227 can shield and protect the vent hole 220, so as to effectively prevent organic waste above the stirring blade 22 in the fermentation chamber 1 from directly blocking the vent hole 220. In addition, in the rotation process of the stirring blade 22, the shielding plate 227 can enable the organic waste to fall to the front of the air outlet side of the vent hole 220, and further the output air can be conveyed outside the stirring blade 22 to a certain degree, so that the air can be more uniformly mixed into the organic waste falling from the shielding plate 227.
