[0031] A support plate 11 is provided at the bottom of the fermentation container 1. The support plate 11 is slidably connected to the fermentation container 1 to facilitate the transfer of mixed materials inside the fermentation container 1.

[0032] The support plate 11 is equipped with a pull ring, which makes it easy to manually pull out the support plate 11.

[0033] Further comprising rotating ring 8, connecting rod 9 and partition plate 10; all sampling containers 7 are rotatably connected with rotating ring 8; all sampling containers 7 are embedded with partition plate 10, and the partition plate 10 is slidably connected with the sampling container 7; all partition plates 10 are fixedly connected with connecting rod 9, and the connecting rod 9 is fixedly connected with the adjacent rotating ring 8.

[0034] All of the cylindrical barrels 2 are provided with flow grooves 22, and the edge positions of the air pipes 4 are located in the corresponding flow grooves 22, and the height of the flow grooves 22 is greater than the height of the air pipes 4; the flow grooves 22 are in communication with the inside of the cylindrical barrels 2.

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

[0036] The cylindrical barrel 2 and the air pipe 4 are provided with a heat insulation layer, which reduces the influence of high temperature heat on the fermentation of the mixed materials during the sterilization process.

[0037] Before using the agricultural and forestry wastes for compost fermentation, the pulverized carbon source materials (straw, wood chips), water, nitrogen source (chicken manure, cow dung, etc.) and microbial inoculum are fully mixed by the existing mixing equipment, and it is necessary to note that the initial water content of the mixed materials is 45% to 65%, and then the fully mixed materials are discharged into the fermentation container 1 by the mixing equipment, in this process, the connecting plate 102, the connecting column 101, the first pushing rod 104 and the second pushing rod 105 are horizontally reciprocated by the electric push rod 103, so as to loosen the mixed materials discharged into the fermentation container 1, and to ensure that the mixed materials discharged into the fermentation container 1 are evenly laid, after the mixed materials are all discharged into the fermentation container 1, the electric push rod 103 stops working, and the mixed materials are fermented.

[0038] In the fermentation temperature rising period of the mixed materials, in order to avoid that the particle size of the particulate matters in the mixed materials is too fine, and the mixed materials are not ventilated well, which leads to the inhibition of aerobic microorganisms and easy anaerobic fermentation, affecting the fermentation effect, in 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℃), the temperature detector will transmit a signal to the gas conveyor, and the gas conveyor will transport air into the connecting ring 3 and the air pipe 4 through the connecting pipe one 5, the air is sprayed out of the air outlet of the air pipe 4 and flows into the mixed materials through the through groove one 21, so as to supplement oxygen to the mixed materials, and to ensure the normal fermentation of the mixed materials; at the same time, the temperature detector transmits a signal to the electric push rod 103, and the electric push rod 103 drives the connecting plate 102, the connecting column 101, the first pushing rod 104 and the second pushing rod 105 to move horizontally and reciprocally, so as to stir the mixed materials, and to ensure the flow of oxygen in the mixed materials, and to ensure the oxygen supplement effect.

[0039] In the high temperature fermentation period of the mixed material, the water content of the mixed material is monitored by the water detector in the fermentation container 1. If the water content is too low (<40%), the water detector controls the conveyor to deliver water to the mixed material through the connecting pipe two 6, the connecting ring 3 and the air pipe 4, so as to supplement water to the mixed material and ensure the normal fermentation of the mixed material. At the same time, the water detector starts the electric push rod 103, so that the electric push rod 103 drives the connecting plate 102, the connecting column 101, the push rod one 104 and the push rod two 105 to move horizontally and reciprocally, so as to turn the mixed material and ensure that the water and the mixed material are in full contact and the water supplement effect is ensured. It should be noted that in the high temperature fermentation period of the mixed material, when the temperature detector detects that the temperature exceeds 65℃, the electric push rod 103 drives the connecting plate 102, the connecting column 101, the push rod one 104 and the push rod two 105 to turn the mixed material, so as to avoid the temperature of the mixed material rising above 75℃, which leads to the reduction of the activity of microorganisms and the formation of spores. In addition, when the mixed material enters the cooling period (<55℃) and the stable period (<35℃), the mixed material is supplemented with water and turned according to the standard (in the cooling period: every 7-12 times of turning the pile, if the water content is too low (<40%), the water is supplemented when the pile is turned; in the stable period: if the temperature difference is less than 2℃ for two times in succession, the turning of the pile can be stopped, and the water content is controlled to be 20%-30%).

[0040] Consider, in the mixed material fermentation process, each stage of fermentation needs to be sampled, and the fermentation state is evaluated, and the existing sampling is carried out by manually inserting the sampling cylinder into the mixed material, and in order to avoid the difference in the fermentation state of the local position of the mixed material, that is, the mixed material needs to be sampled at multiple points, resulting in cumbersome manual sampling operation (after sampling one sample, the sample needs to be discharged and then sampled), and for the mixed material in the middle of the fermentation container 1, limited by the volume of the fermentation container 1, sampling is difficult; Therefore, by additionally arranging the sampling container 7 in the cylindrical barrel 2, three through grooves two 41 are arranged on the air pipe 4, the through grooves two 41 are staggered with the three through grooves one 21, and the cylindrical barrel 2 matrix distribution divides the mixed material in the fermentation container 1 into nine horizontal and vertical regions, if the mixed material in the upper left region of the fermentation container 1 needs to be sampled, only the connecting ring 3 and the air pipe 4 in the upper left cylindrical barrel 2 need to be pulled out horizontally, from front to back, the through groove two 41 is communicated with the first three through grooves one 21 of the cylindrical barrel 2, the last through groove one 21 is directly communicated with the inside of the cylindrical barrel 2, and the mixed material in the upper left region of the fermentation container 1 can fall into the sampling container 7 through the through groove one 21 and the through groove two 41, realizing the sampling work of the mixed material in the upper left region of the fermentation container 1, if the mixed material in other regions of the fermentation container 1 needs to be sampled, repeat the above operation, and pull out the connecting ring 3 and the air pipe 4 in the corresponding position horizontally; In this way, the sampling cylinder is manually held, convenient sampling is realized, and multi-region sampling is realized as needed; It should be noted that when sampling, the length of the air pipe 4 pulled out can be used to control the degree of shielding of the cylindrical barrel 2 to the through groove two 41, which is convenient for controlling the sampling amount; After sampling is completed, the connecting ring 3 and the air pipe 4 are pushed to the initial position, and then the sampling container 7 is pulled out from the cylindrical barrel 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, and the connecting rod 9 and the partition plate 10 follow the rotation, 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, the sample amount is reduced, and the subsequent evaluation is affected.

[0042] In order to avoid the sampling container 7 to cause pollution to the mixed material sample, according to the sampling standard, before sampling, the sampling container 7 must be sterilized by using high temperature steam; for this purpose, by opening the flow groove 22 on the through groove 21, and the flow groove 22 is communicated with the cylindrical barrel 2, before sampling, manually rotate the connecting ring 3 and the air pipe 4 first, make the air outlet hole on the air pipe 4 shift to the flow groove 22, and the edge position of the air pipe 4 located outside the flow groove 22 is in close contact with the cylindrical barrel 2, then start the gas conveying machine to convey high temperature steam into the flow groove 22 through the connecting pipe 1, the connecting ring 3 and the air pipe 4, the high temperature steam flows from the flow groove 22 into the cylindrical barrel 2, and the sampling container 7 is sterilized by steam, so that the automatic sterilization of the sampling container 7 before sampling is realized, without manually taking out the sampling container 7 one by one for sterilization, reducing the labor intensity of the workers; it should be noted that the cylindrical barrel 2 and the air pipe 4 are provided with a heat insulation layer to reduce the influence of high temperature heat on the fermentation of the mixed material during sterilization.

[0043] It should be noted that after the mixed material completes fermentation, the workers use tools to pull the bearing plate 11 out of the fermentation container 1, so that the mixed material in the fermentation container 1 can be easily transferred out.

[0044] It should be noted that in order to avoid the mixed material remaining between the through groove 21 and the air pipe 4, after the bearing plate 11 is pulled out of the fermentation container 1, the connecting ring 3 and the air pipe 4 are rotated clockwise from front to back by hand, the air pipe 4 forces the cylindrical barrel 2 to rotate, after the connecting ring 3 and the air pipe 4 are rotated clockwise by one hundred and eighty degrees, the through groove 21 and the air pipe 4 air outlet hole downward, at this time, stop rotating the connecting ring 3 and the air pipe 4, the mixed material remaining between the through groove 21 and the air pipe 4 directly falls downward, avoiding waste, at the same time, the gas conveying machine can be started, the gas conveying machine conveys air into the connecting ring 3 and the air pipe 4 through the connecting pipe 1, the air is discharged from the air outlet hole on the air pipe 4 to blow the remaining mixed material, achieving better cleaning effect.

[0045] Example 2

[0046] Based on example 1, as shown in Figures 2-3 The fermentation container 1 is provided with a plurality of DD motors, all the rotating parts of the DD motors are fixedly connected with the corresponding cylindrical barrels 2, when it is needed to make the through groove 21 and the air pipe 4 air outlet hole downward, the cylindrical barrels 2 are counterclockwise rotated by the DD motor, without manually rotating the connecting ring 3 and the air pipe 4 to drive the cylindrical barrels 2 to rotate, reducing the labor intensity of the workers.

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

[0048] When the mixed material is sampled, the electric push rod 103 can drive the connecting plate 102, the connecting column 101, the push rod one 104 and the push rod two 105 to move horizontally and reciprocatingly in a small range, when the push rod two 105 moves, the push rod two 105 pushes the mixed material, so that the mixed material can enter the cylindrical barrel 2 better, and further, in order to facilitate the pushing of the mixed material, a plurality of push plates 110 are additionally arranged, and the plurality of push plates 110 are located above the through groove one 21 corresponding to the cylindrical barrel 2, and the push plates 110 are arranged in an inclined manner, when the electric push rod 103 drives the push rod one 104 and the push rod two 105 to move horizontally and reciprocatingly in a small range, the push plates 110 move reciprocatingly in a small range synchronously, the push plates 110 push the mixed material, which is beneficial to push the mixed material around the sampling point to the through groove one 21.
