[0019] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0020] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures. Example

The bottom of the shed is equipped with a manure collection trough 104 and a material guide channel is provided at the end of the collection trough 104. The manure-scooping structure is located at the head end of the collection tank 104. It moves along the collection tank 104 and pushes the feces and fallen objects in the collection tank 104 into the guide channel at the tail end of the collection tank 104.

The sealing holes are provided with sealing structures 30, which have semi-permeable membranes that allow gas and liquid to pass through. The inner cylinder 203 is fitted inside the outer cylinder 202. It includes an inner ring and an outer ring. The inner ring has an oxygen supply chamber 2032 inside. A fermentation chamber 200 is provided between the inner ring and the outer ring. The fermentation chamber 200 has a feed inlet 2031 on the outside. The fermentation chamber 200 has a vent hole on the inside and a hydrophobic microporous membrane at the vent hole.

An air intake mechanism, rotatably connected to one end of the inner cylinder 203 and communicating with the oxygen supply chamber 2032, provides gas with humidity and temperature to regulate the humidity and temperature within the fermentation chamber 200. In this scheme, when fermentation requires feeding, the water discharge section of the pool 103 flushes the feces, and the feces are pushed into the feed channel by the shovel structure. Then, the feed inlets 2031 and feed holes 2021 of the two cylinders are rotated to align with the outlet of the feed channel for feeding. After feeding, one cylinder is rotated individually to seal the feed inlet 2031 of the inner cylinder 203 through the sealing structure 30. After sealing, the water permeability of the membrane is utilized to rotate the feed inlet 2031 of the cylinder downwards or to quickly expel the internal water through rotation. During fermentation, gas is introduced from the inside through the air intake mechanism to regulate oxygen supply, temperature, and humidity. During the aeration process, the two cylinders rotate to achieve a stirring function, providing favorable conditions for fermentation and improving fermentation efficiency.

The drive motor 2013 is connected to the feeding shaft 2012 in a transmission manner; When the drive motor 2013 drives the feeding shaft 2012 to rotate, causing the feeding trough to face upwards, the material falls into the feeding trough. When the rotation turns the feeding trough downwards, the material falls and enters the guide cylinder 2014.
