[0030] The loosening assembly includes a connecting column 101, a connecting plate 102, an electric push rod 103, a first push rod 104 and a second push rod 105; Nine connecting columns 101 distributed in a matrix are slidably connected to the fermentation container 1, and the connecting columns 101 are located directly above the corresponding cylindrical barrels 2; All the connecting columns 101 located on the same vertical line are fixedly connected to a connecting plate 102; Six electric push rods 103 distributed in a matrix are fixedly connected to the fermentation container 1, and the telescopic part of the electric push rod 103 is fixedly connected to the adjacent connecting plate 102; A number of first push rods 104 are fixedly connected to all the connecting columns 101, and the first push rods 104 and the adjacent connecting columns 101 are combined into a cross shape; A number of second push rods 105 are fixedly connected to all the first push rods 104, and the second push rods 105 and the adjacent first push rods 104 are combined into a cross shape.

[0031] A bearing plate 11 is arranged at the bottom of the fermentation container 1, and the bearing plate 11 is slidably connected to the fermentation container 1, which is convenient for the transfer of the mixed materials inside the fermentation container 1.

[0032] A pull ring is provided on the bearing plate 11, which is convenient for manually pulling out the bearing plate 11.

[0033] It also includes a rotating ring 8, a connecting rod 9 and a partition plate 10; a rotating ring 8 is rotatably connected to all the sampling containers 7; a partition plate 10 is embedded in all the sampling containers 7, and the partition plate 10 is slidably connected to the sampling container 7; a connecting rod 9 is fixedly connected to all the partition plates 10, and the connecting rod 9 is fixedly connected to the adjacent rotating ring 8.

[0034] All the cylindrical barrels 2 are provided with flow grooves 22, the edge position of the air pipe 4 is located in the corresponding flow groove 22, and the height of the flow groove 22 is greater than the height of the air pipe 4; the flow groove 22 is communicated with the inside of the cylindrical barrel 2.

[0035] The cylindrical barrel 2 is rotatably connected to the fermentation container 1.

[0036] The cylindrical barrel 2 and the air pipe 4 are provided with heat insulation layers to reduce the influence of the high temperature heat during disinfection on the fermentation of the mixed materials.

[0037] Before using agricultural and forestry waste for composting fermentation, the crushed carbon source materials (straw, wood chips), water, nitrogen sources (chicken manure, cow manure, etc.) and microbial inoculants are fully mixed by existing mixing equipment. It should be noted that the initial water content of the mixed materials is 45% - 65%. Then, the fully mixed materials are discharged into the fermentation container 1 by the mixing equipment. During this process, the electric push rod 103 drives the connecting plate 102, the connecting column 101, the first push rod 104 and the second push rod 105 to move horizontally back and forth, loosen the mixed materials discharged into the fermentation container 1, and ensure that the mixed materials discharged into the fermentation container 1 are evenly spread. After all the materials to be mixed are discharged into the fermentation container 1, the electric push rod 103 stops working, and the mixed materials start to ferment.

[0038] During the temperature rising period of the mixed materials fermentation, to avoid that the particle size of the particles in the mixed materials is too fine, the ventilation of the mixed materials is poor, resulting in the inhibition of aerobic microorganisms and easy anaerobic fermentation, which affects the fermentation effect. During the fermentation process, the temperature of the mixed materials is monitored by the temperature detector in the fermentation container 1. If the fermentation temperature of the mixed materials is too low (<45°C), the temperature detector will transmit the signal to the gas conveyor. The gas conveyor transports air into the connecting ring 3 and the air pipe 4 through the first connecting pipe 5. The air jets out from the air holes of the air pipe 4 and flows into the mixed materials through the first through groove 21 to supply oxygen to the mixed materials, ensuring the normal fermentation of the mixed materials; at the same time, the temperature detector transmits the signal to the electric push rod 103, and the electric push rod 103 drives the connecting plate 102, the connecting column 101, the first push rod 104 and the second push rod 105 to move horizontally back and forth to turn over the mixed materials, ensuring the circulation of oxygen in the mixed materials and ensuring the oxygen supply effect.

[0039] During the high-temperature period of the fermentation of the mixed material, the water content detector in the fermentation container 1 monitors the water content of the mixed material. If the water content is too low (<40%), the water content detector controls the conveyor to transport water into the mixed material through the second connecting pipe 6, the connecting ring 3, and the air pipe 4 to replenish water for the mixed material to ensure normal fermentation of the mixed material. At the same time, the water content detector activates the electric push rod 103, causing the electric push rod 103 to drive the connecting plate 102, the connecting column 101, the first push rod 104, and the second push rod 105 to move horizontally back and forth to turn the mixed material, ensuring full contact between the water and the mixed material and ensuring the water replenishment effect. It should be noted that during the high-temperature period of the fermentation of the mixed material, when the temperature detector monitors that the temperature exceeds 65°C, the electric push rod 103 drives the connecting plate 102, the connecting column 101, the first push rod 104, and the second push rod 105 to turn the mixed material to prevent the temperature of the mixed material from rising above 75°C, resulting in a decrease in microbial activity and the formation of spores. In addition, when the mixed material enters the cooling period (<55°C) and the stable period (<35°C), water replenishment and turning of the mixed material are carried out according to the standards (cooling period: turn the pile every 7 - 12 times. If the water content is too low (<40%), replenish water when turning the pile; stable period: when the continuous temperature difference is less than 2°C for 2 consecutive times, the pile turning can be stopped, and the water content is controlled at 20% - 30%).

[0040] It is considered that during the fermentation process of the mixed material, sampling is required at each stage of fermentation to evaluate the fermentation state. The existing sampling is carried out by manually holding a sampling cylinder and inserting it into the mixed material. In order to avoid differences in the fermentation state of local positions of the mixed material, that is, it is necessary to take multiple samples from the mixed material, resulting in cumbersome manual sampling operations (after taking one sample, the sample needs to be discharged before sampling again). Moreover, for the mixed material in the middle of the fermentation container 1, due to the volume limitation of the fermentation container 1, it is difficult to sample. Therefore, by adding a sampling container 7 in the cylindrical cylinder 2, three second through grooves 41 are opened on the air pipe 4, and the second through grooves 41 and the three first through grooves 21 are staggered. And the cylindrical cylinders 2 are distributed in a matrix to divide the mixed material in the fermentation container 1 into nine horizontal and vertical regions. If it is necessary to sample the mixed material in the upper left region of the fermentation container 1, only need to horizontally pull out the connecting ring 3 and the air pipe 4 in the upper left cylindrical cylinder 2 outward. Looking from front to back, the second through groove 41 is connected to the first three first through grooves 21 of the cylindrical cylinder 2, and the last first through groove 21 is directly connected to the inside of the cylindrical cylinder 2. The mixed material in the upper left region of the fermentation container 1 can fall into the sampling container 7 through the first through groove 21 and the second through groove 41, realizing the sampling work of the mixed material in the upper left region of the fermentation container 1. If it is necessary to sample the mixed material in other regions of the fermentation container 1, repeat the above operation and horizontally pull out the connecting ring 3 and the air pipe 4 at the corresponding position outward; in this way, different from manually holding a sampling cylinder for sampling, convenient sampling is realized, and multi-region sampling on demand is realized; it should be noted that during sampling, the shielding degree of the cylindrical cylinder 2 on the second through groove 41 can be controlled according to the length of the air pipe 4 pulled out, which is convenient for controlling the sampling amount; after sampling, push the connecting ring 3 and the air pipe 4 to the initial position, and then pull out the sampling container 7 from the cylindrical cylinder 2.

[0041] It should be noted that when pulling out the sampling container 7, in order to avoid the mixed material in the sampling container 7 from falling, before pulling out the sampling container 7, manually rotate the rotating ring 8 counterclockwise from right to left. The connecting rod 9 and the partition plate 10 rotate accordingly, and the partition plate 10 closes the opening of the sampling container 7, and then stop rotating the rotating ring 8. In this way, when pulling out the sampling container 7, the mixed material in the sampling container 7 can be avoided from falling, and the reduction of the sample amount can be avoided, which affects the subsequent evaluation.

[0042] To avoid contamination of the mixed material sample by the sampling container 7, according to the sampling standard, before sampling, the sampling container 7 must be disinfected with high-temperature steam; for this purpose, by opening a flow groove 22 on the first through groove 21, and the flow groove 22 is communicated with the inside of the cylindrical barrel 2, before sampling, the worker first rotates the connecting ring 3 and the air pipe 4 manually, so that the air outlet holes on the air pipe 4 are transferred into the flow groove 22, and the edge position of the air pipe 4 outside the flow groove 22 is in close contact with the cylindrical barrel 2, and then the gas conveyor is started to convey high-temperature steam into the flow groove 22 through the first connecting pipe 5, the connecting ring 3 and the air pipe 4. The high-temperature steam flows from the flow groove 22 into the cylindrical barrel 2 to perform steam disinfection treatment on the sampling container 7. In this way, the automatic disinfection work of the sampling container 7 before sampling is realized, and there is no need for the worker to take out the sampling containers 7 one by one for disinfection work, reducing the labor intensity of the worker; it should be noted that heat insulation layers are provided in the cylindrical barrel 2 and the air pipe 4 to reduce the influence of the high-temperature heat during the disinfection process on the fermentation of the mixed material.

[0043] It should be noted that after the fermentation of the mixed material is completed, the worker uses tools to pull out the bearing plate 11 from the fermentation container 1, and then the mixed material in the fermentation container 1 can be easily transferred out.

[0044] It should be noted that to avoid the mixed material remaining between the first through groove 21 and the air pipe 4, after pulling out the bearing plate 11 from the fermentation container 1, the worker rotates the connecting ring 3 and the air pipe 4 clockwise by looking from the front to the back manually. The air pipe 4 forces the cylindrical barrel 2 to rotate accordingly. After the connecting ring 3 and the air pipe 4 rotate 180 degrees clockwise, the first through groove 21 and the air outlet holes of the air pipe 4 face downwards. At this time, the rotation of the connecting ring 3 and the air pipe 4 is stopped, and the mixed material remaining between the first through groove 21 and the air pipe 4 directly falls downwards, avoiding waste. At the same time, the gas conveyor can be started, and the gas conveyor conveys air into the connecting ring 3 and the air pipe 4 through the first connecting pipe 5. The air is discharged from the air outlet holes on the air pipe 4 to blow the remaining mixed material, achieving a better cleaning effect.

[0045] Embodiment 2

[0046] On the basis of Embodiment 1, as Figures 2-3 shown, a number of DD motors are provided in the fermentation container 1, and the rotating parts of all the DD motors are fixedly connected to the corresponding cylindrical barrels 2. When it is necessary to make the first through groove 21 and the air outlet holes of the air pipe 4 face downwards, the cylindrical barrel 2 is driven to rotate counterclockwise by the DD motor, without the need for the worker to rotate the connecting ring 3 and the air pipe 4 to drive the cylindrical barrel 2 to rotate, reducing the manual labor.

[0047] The loosening assembly further includes a push plate 110; six push plates 110 are fixedly connected to all the connecting columns 101, and the other end of the push plate 110 is fixedly connected to the adjacent first push rod 104; the push plate 110 is inclined relative to the first push rod 104 and the second push rod 105.

[0048] When sampling the mixed material, the electric push rod 103 can be activated to drive the connecting plate 102, the connecting column 101, the first push rod 104 and the second push rod 105 to move horizontally in a small amplitude reciprocating manner. When the second push rod 105 moves, the second push rod 105 pushes the mixed material, so that the mixed material can better enter the cylindrical barrel 2. Further, in order to facilitate the pushing of the mixed material, a plurality of push plates 110 are added. The plurality of push plates 110 are located above the first through groove 21 of the corresponding cylindrical barrel 2, and the push plates 110 are inclined. When the electric push rod 103 drives the first push rod 104 and the second push rod 105 to move horizontally in a small amplitude reciprocating manner, the push plates 110 move in a small amplitude reciprocating manner synchronously. The push plates 110 push the mixed material, which is beneficial to push the mixed material around the sampling point towards the first through groove 21.
