The closed composting fermentation device of the utility model can seal the fermentation bin through the closing device, and the feed port is convenient for the staff to compost after the closing device is opened, the overall structure is simple, the fermentation effect is good and the fermentation efficiency is high.

[0004] With regard to the above-mentioned related technologies, in the prior art, workers use a fermentation bin to pile up livestock and poultry manure, and use the cooperation of a fan and a deodorization bin to increase the oxygen content of the livestock and poultry manure. The livestock and poultry manure itself contains a certain amount of moisture. Too much moisture will make the sugar concentration too low, which will inhibit the growth of yeast. However, in the prior art, the position of the exhaust hole on the air supply pipe is fixed, and the accumulated livestock and poultry manure is affected by the wind at the exhaust hole to a limited extent, so that the moisture in other positions of the livestock and poultry manure cannot be fully dissipated, resulting in uneven distribution of yeast growth in the livestock and poultry manure, which reduces the fermentation effect of the livestock and poultry manure in the fermentation bin. Summary of the invention

[0005] In order to improve the fermentation effect of livestock and poultry manure in a fermentation bin, the present application provides a fermentation bin.

[0037] When closing the silo 1, the staff rotates the flip plate 21 to make the flip plate 21 cover the air inlet slot 11. At this time, the magnet 211 fits the metal block 13, and then starts the choke motor 23 to rotate the driving rod 231. The driving column 232 cooperates with the driving slot to drive the connecting rod 221 to move, so that the three choke plates 22 move synchronously until they cover the exhaust port 12, thereby achieving the effect of closing the silo 1.

[0038] Reference Figure 4, a stirring assembly 3 is arranged in the silo 1, and the stirring assembly 3 includes a first motor 31, a moving seat 32 and a stirring frame 33. A first driving assembly 4 is arranged in the silo 1, and the first driving assembly 4 includes a moving vehicle 41, a transverse motor 42, a connecting gear 43 and a fixed rack 44. Both sides of the silo 1 in the width direction are fixedly connected with fixed rails, and the moving vehicle 41 is an electric vehicle, and the moving vehicle 41 moves on the fixed rails, and a support beam 411 is fixedly connected between the two moving vehicles 41.

The first motor 31 is installed on the movable seat 32 and connected to the rotating shaft through a belt drive.

[0041] When stirring up livestock and poultry manure, the staff starts the moving vehicle 41 to move the support beam 411, then starts the transverse motor 42 to drive the connecting gear 43 to rotate, so that the moving seat 32 moves on the support beam 411, and then starts the first motor 31 to rotate the rotating shaft, driving the stirring frame 33 to rotate, thereby achieving the effect of stirring up livestock and poultry manure.

[0042] The implementation principle of a fermentation bin in Example 1 of the present application is as follows: when dissipating moisture in livestock and poultry manure, the staff keeps the air inlet slot 11 and the air outlet 12 connected, then starts the moving vehicle 41 to move the support beam 411, then starts the transverse motor 42 to drive the connecting gear 43 to rotate, so that the moving seat 32 moves on the support beam 411, then starts the first motor 31 to rotate the rotating shaft, and drives the stirring frame 33 to rotate, so that the livestock and poultry manure releases moisture. After stirring the livestock and poultry manure, the staff rotates the flip plate 21 to make the magnet 211 fit the metal block 13 to close the air inlet slot 11, then starts the air blocking motor 23 to rotate the driving rod 231, moves the connecting rod 221, and drives the three air blocking plates 22 to move synchronously until the air blocking plates 22 cover the air outlet 12 to close the silo 1, thereby achieving the effect of fermenting livestock and poultry manure.

[0043] The staff uses the exhaust fan 121 to ventilate the fermentation bin, and cooperates with the stirring component 3 to stir the livestock and poultry manure. The livestock and poultry manure comes into contact with the flowing air during the stirring process, which increases the oxygen content of the livestock and poultry manure and allows the moisture inside the livestock and poultry manure to be fully dissipated. In this way, the water content in the livestock and poultry manure can be further reduced to increase the sugar concentration of the livestock and poultry manure, so that the yeast growth in the livestock and poultry manure is as evenly distributed as possible. The staff can better control the fermentation process of the livestock and poultry manure, promote the growth and metabolism of yeast in the livestock and poultry manure, and improve the fermentation effect of the livestock and poultry manure in the fermentation bin.
