Livestock and poultry manure contains a large number of pathogenic bacteria and parasites. If not properly handled, it will become a source of infection for livestock and poultry infectious diseases, parasitic diseases and zoonoses. In addition, the manure has a bad odor and contains a large amount of nitrogen, phosphorus, potassium and some heavy metal elements. Improper handling can easily cause pollution to the soil, water sources, and air, endangering human health. At present, domestic livestock and poultry manure fermentation equipment is mainly tower type and open flip type. For example, utility model patent CN208292886U discloses a livestock and poultry manure fermentation tower, including a fermentation tank and a tower body, which are connected by an air inlet pipe, and an air pump is arranged on the air inlet pipe. A condensation device is arranged between the tower body and the air inlet pipe, and the air outlet of the condensation device is located inside the tower body.

[0024] like Figure 1-3 As shown, a cleanable low-temperature fermentation device comprises a sealed box body 1 and a frame 2 arranged inside the box body 1, the box body 1 and the frame 2 are rectangular, the outside of the box body 1 is covered with a heat preservation layer, and multiple layers of closed conveying chain nets 3 arranged up and down are arranged in the box body 1, each layer of the conveying chain net 3 is supported by a sprocket 6 of a driving shaft 4 and a driven shaft 5 of each layer, and the driving shaft 4 is driven to rotate by a motor 7 outside the box body 1, and adjacent conveying chain nets 3 are arranged in a staggered manner, so that the discharge end of the upper conveying chain net 3 is located at the lower conveying chain net 3. At the feeding end of the chain conveying net 3, a feeding port 8 is provided in the box body 1 above the top conveying chain net 3, and a material mixing auger 15 is provided in the box body 1 below the feeding port 8. A plurality of evenly distributed material mixing ports are provided at the bottom of the material mixing auger 15, and the material mixing ports are evenly arranged above the feeding end of the top conveying chain net 3, and a discharging port 9 is provided below the discharging end of the bottom conveying chain net 3, and the discharging port 9 extends to the inside of the box body 1 through a U-shaped groove 16, and the U-shaped groove 16 is provided with a discharging auger 17 for discharging the material.

[0025] A cleaner 10 is provided on the upper surface of the lower part of each layer of the conveyor chain net 3. The cleaner 10 is a V-shaped scraper structure, and the direction pointed by the central bending part of the scraper structure is opposite to the movement direction of the conveyor chain net 3 of this layer.

[0026] The bottom of the box body 1 is provided with left-right symmetrically inclined guard plates 11, the upper ends of the guard plates 11 are fixedly connected to the side walls of the box body 1, and a gap is left between the lower ends of the two guard plates 11 to form a discharge channel, and a cleaning auger 12 for discharging materials outward is provided in the discharge channel.

[0027] A breaking device is provided above the multi-layer conveyor chain network 3 , and the breaking device includes a breaking shaft 13 and rotary tillage blades 14 arranged at intervals on the breaking shaft 13 . The breaking shaft 13 is driven to rotate by a motor 7 outside the box body 1 .

[0028] The driving shaft 4 and the power output end of the motor 7 , as well as the motor 7 and the rotating shafts of each auger are respectively connected through a coupling 18 .

[0029] Working principle of the utility model: the internal layered structure is adopted, and the conveying chain net 3 of each layer can rotate freely. The livestock and poultry manure is transported to the discharge port 8 through other auxiliary feeding equipment, and the material leveling auger 15 evenly distributes the manure on the uppermost conveying chain net 3. All the conveying chain nets 3 are driven to rotate by the motor 7 to transport the manure forward layer by layer. As the material of the upper layer is full, the material of the upper layer falls to the adjacent lower layer. When the material of the lower layer is full, the material will continue to fall to the lower layer until all layers are evenly filled with material. All the conveying chain nets 3 stop running, and the manure begins to ferment. Microorganisms are used to decompose organic matter in the manure. At the same time, due to the closed setting of the box body 1, it can also be connected to the heat recovery, deodorization device, and air supply device. The waste gas generated during fermentation is recycled through heat recovery to recycle the heat in the waste gas, saving energy consumption. The exchanged waste gas is discharged through the deodorization device, which meets the requirements. Environmental protection requirements, after a period of time, the bottom layer of fermentation is completed, the equipment is started, the conveyor chain network 3 is operated, the material is sent to the discharge port 9, and the material is sent to other external equipment through the discharge auger 17 and transported to the designated location. After that, a layer of material is discharged and a layer of material is added every day to achieve the effect of continuous fermentation. In this process, the breaking device is operated at the same time, that is, the motor 7 drives the rotary tillage blades 14 arranged at intervals on the breaking shaft 13 to rotate, and the rotary tillage blades 14 are used to break up and turn over the layer of material, thereby increasing the fermentation effect, improving production efficiency, turning waste into treasure, and solving the problem of feces polluting the environment.

[0030] In addition, the utility model is provided with a cleanable device, namely a sweeper 10. The sweeper 10 is similar to a V-shaped scraper structure. The sweeper 10 is installed near the driven shaft of each layer of the conveyor chain network 3. When the feces and dirt partially missed on the conveyor chain network 3 falls onto the surface of the conveyor chain network 3 with the sweeper 10, the feces and dirt will gradually move to the position of the sweeper 10 due to the operation of the conveyor chain network 3. Under the action of the sweeper 10, the feces and dirt are gradually accumulated. Then, the feces and dirt continue to run, and the feces and dirt move to both sides under the guidance of the V-shaped scraper structure, and gradually fall down, and finally fall into the cleaning auger 12 to transport the feces and dirt out. The feces and dirt that fall into the middle of the chain network are generally inconvenient to clean, and are difficult to clean manually. If they are not cleaned for a long time, when the feces and dirt reach a certain amount, the chain network will sag more, increase resistance, and finally may cause the equipment to be unable to operate. The design of the sweeper 10 can solve this problem, extend the service life of the equipment, save labor, and improve production efficiency.

[0031] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by any person skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
