Description

Technical Field

[0001] The utility model relates to the technical field of manure composting, in particular to a partitioned longitudinal homogenizing stirring fermentation box specially used for manure composting experiments. Background Art

[0002] Agricultural organic wastes such as livestock and poultry manure, rural domestic waste rich in organic matter, and crop straw contain rich nutrients such as organic matter, nitrogen, phosphorus, potassium, and various trace elements, and are all high-quality raw materials for fertilizer. Converting agricultural organic wastes such as livestock and poultry manure, rural domestic waste, and crop straw into high-quality organic fertilizers is one of the effective ways to utilize agricultural organic waste resources. Composting refers to the microbiological process of artificially promoting the biochemical transformation of biodegradable organic matter into stable humus by relying on microorganisms such as bacteria, fungi, and actinomycetes that are widely distributed in nature. The maturation rate of materials in the process of manure composting is related to parameters such as material humidity, temperature, and light intensity. In order to truly promote the use of manure composting technology, multiple fermentation tests on manure composting treatment are carried out in laboratories or greenhouses with the help of fermentation boxes, so as to screen out the parameters that are most conducive to improving the efficiency of manure composting.

[0003] In order to better mix the fermenting manure and liquid, thereby enhancing the interaction between them, a corresponding stirring mechanism is usually installed inside the manure composting test fermentation box in the prior art to stir the manure. However, the manure itself has a high viscosity, and the stacking fermentation process is greatly affected by its own weight and air contact. Manure often contains a small amount of solid impurities. During the rotation of the stirring mechanism inside the fermentation box, these solid impurities can easily come into contact with the rotating shaft and blades of the stirring mechanism, causing the rotating shaft and blades of the stirring mechanism to be easily damaged during long-term use, thereby reducing the service life of the stirring mechanism. There are also blind spots in the external stirring method, making it difficult to homogenize all the space in the fermentation box, which has an adverse effect on the fermentation treatment efficiency of the manure inside the fermentation box and will also affect the accurate acquisition of the test results.

[0031] As a technical optimization scheme in the utility model, the stirring mechanism includes two rotating shafts 18, which are symmetrically installed inside the mobile frame 7, and the outer walls of the two rotating shafts 18 are installed with multiple stirring blades 19, and two filter plates 8 are rotatably installed on both sides of the mobile frame 7. Two second drive motors are preset inside the mobile frame 7, and the output ends of the two second drive motors are respectively connected to the ends of the two rotating shafts 18, thereby driving the two rotating shafts 18 and the multiple stirring blades 19 to rotate inside the box body 1, mixing and stirring the manure being fermented inside the box body 1, and improving the manure fermentation efficiency; the two filter plates 8 are rotatably connected to the mobile frame 7 through the electric rotating rods set at both ends, and a third drive motor is preset inside the mobile frame 7 near the two filter plates 8, and the output end of the third drive motor is connected to the electric rotating rod at one end of the filter plate 8, thereby driving the filter plate 8 to rotate and adjust.

[0032] As a technical optimization solution in the present invention, a fixed rod 20 is installed at the center of the mobile frame 7, and a temperature sensor 21 is provided at the top of the fixed rod 20. The temperature sensor 21 is a PT100 temperature sensor in the prior art. By setting the temperature sensor 21, the temperature of the feces in the middle position of the box body 1 can be measured in real time to ensure that the temperature inside the box body 1 is within a normal range, and to avoid the problem that the temperature inside the box body 1 is too low or too high, causing the microorganisms to enter a dormant state or die in large numbers, and the fermentation is slow or even stopped.

[0033] In the utility model, when it is necessary to conduct a manure fermentation test, the manure can be put into the box body 1, and it is determined whether additional water needs to be added according to the water content of the manure. Then, the sliding of the movable plate 6 on the top of the movable frame 2 can be controlled to drive the sealing film 5 to unfold on the top of the movable frame 2, and the top of the sealing film 5 can be pressed so that the sealing strip 15 at the bottom thereof is connected and adapted to the sealing groove 17, and the gap between the sealing film 5 and the movable frame 2 is blocked, so as to facilitate the sealed fermentation of manure inside the box body 1.

[0037] After the feces and sewage inside the box body 1 are fermented for a period of time, the telescopic ends of the multiple electric telescopic rods 3 can be controlled to extend upward together, pushing the moving frame 2 to move upward, so that the opening on the top of the box body 1 is in contact with the external air, which is convenient for the gas generated by the fermentation inside the box body 1 to be discharged to the outside, and it is also convenient for the outside air to contact with the feces and sewage, thereby improving the fermentation efficiency of the feces and sewage; if the telescopic ends of the multiple electric telescopic rods 3 are powered off or other faults occur during use, the moving plate 6 can be manually pushed to create a gap between the sealing film 5 and the moving frame 2, thereby avoiding the situation where the feces and sewage inside the box body 1 cannot be ventilated when the electric telescopic rods 3 cannot be used.

[0038] And when the telescopic ends of the multiple electric telescopic rods 3 are controlled to extend upward, the two filter plates 8 can be controlled to rotate downward to a horizontal state. With the upward and downward telescopic movements of the telescopic ends of the multiple electric telescopic rods 3, the two filter plates 8 are driven to vertically flip the fermenting feces and sewage inside the box body 1, and the positions of the two horizontal filter plates 8 inside the box body 1 can be adjusted by means of the rotation of the driving screw 11, so as to facilitate the vertical flipping of all feces and sewage inside the box body 1, increase the contact area between feces and sewage and the outside air, and further improve the efficiency and quality of feces and sewage fermentation.
