Description

Technical Field

[0001] The invention relates to the technical field of organic fertilizer fermentation, in particular to an organic fertilizer fermentation device with a stirring function. Background Art

[0002] The organic fertilizer fermentation device is a device used to ferment organic materials (such as livestock and poultry manure) and convert them into organic fertilizer. The existing organic fertilizer fermentation device has a simple stirring method, mostly a single stirring shaft with fixed stirring blades. As the material gradually ferments, the water content of the material gradually decreases. When the water content drops to a certain level, the material is prone to agglomeration, and the material particles adhere to each other and gather together to form a larger block structure. At the same time, the surface of the material is prone to crusting. The surface crust not only blocks the entry of oxygen, but also increases the difficulty of stirring. What is more serious is that the material will be stratified. Materials of different components are unevenly dispersed inside the device, and the difference in the properties of the upper and lower layers of materials gradually increases. At this time, the fixed stirring blades are difficult to break the agglomeration of the material, and it is also difficult to solve the problem of crusting on the surface of the material and the stratification between the materials. The existence of these problems makes it difficult to fully stir the material, resulting in uneven fermentation of the material, seriously affecting the quality and fermentation efficiency of the organic fertilizer, and unable to meet the requirements for quality stability in large-scale fermentation production.

[0022] like Figure 2-Figure 7 As shown, an auger sleeve 21 is rotatably connected between two adjacent rotating sleeves 11, and each auger sleeve 21 is fixedly connected with a plurality of crushing plates 22, which are fixedly connected to the tank body 2, and a plurality of crushing plates 22 are circumferentially distributed on adjacent auger sleeves 21, and a gas passage is provided in the auger sleeve 21, and the gas passage in the auger sleeve 21 is connected with the gas passage in the adjacent rotating sleeve 11, and the gas passage in the auger sleeve 21 away from the side of the motor 4 is connected with the exhaust box 5, and all the auger sleeves 21 and all the rotating sleeves 11 together form a material conveying pipeline, and strip-shaped protrusions and block-shaped protrusions are provided on the crushing plate 22, and the front and rear sides of the crushing plate 22 are provided with There are strip-shaped protrusions, the shape of the strip-shaped protrusions on the crushing plate 22 is wavy, the shape of the block-shaped protrusions on the crushing plate 22 is serrated, and the crushing plate 22 is in an inclined state, which is used to increase the contact area between the crushing plate 22 and the material, thereby improving the crushing effect of the material and better crushing the agglomerated material. The rotating shaft 8 is fixedly connected with a connecting piece 31, and the connecting piece 31 is used to form an auger in combination with the spiral piece 7. After the connecting piece 31 and the spiral piece 7 form an auger, the deflection angle of the stirring plate 10 is the largest at this time. The stirring plate 10 is limited by the connecting piece 31 to prevent the deflection angle of the stirring plate 10 from being too large, which affects the stirring effect of the stirring plate 10 on the material.

[0023] When using the device for organic fertilizer fermentation, the staff first pre-treats the prepared animal manure (hereinafter referred to as material instead of animal manure) (such as dehydration, impurity removal, etc.). The material is initially a solid-liquid mixture. Then the staff opens the feed port and slowly pours the material into the tank body 2 through the feed port. The material in the tank body 2 gradually rises and is poured into the feed pipeline composed of the auger sleeve 21 and the rotating sleeve 11. When the material in the tank body 2 reaches a predetermined height, the feeding is stopped. At this time, the material liquid level is flush with the upper side of the spiral sheet 7, and most of the solids are located at the lower part of the whole material. Then the staff closes the feed port and turns on the motor 4. The motor 4 drives the spiral sheet 7 and the rotating shaft 8 to rotate clockwise through the main shaft 6 (the direction hereinafter referred to as Figure 3 Taking the top view as an example), the rotating shaft 8 drives the stirring plate 10 to rotate clockwise, the spiral piece 7 rotates clockwise and drives the material in the feeding pipeline composed of the auger sleeve 21 and the rotating sleeve 11 to turn up and down, and the stirring plate 10 drives the material to stir horizontally. When the moisture content of the material is high, the material fluidity is high. At this time, the resistance encountered by the stirring plate 10 is small. The spiral piece 7 and the stirring plate 10 work together to make the material turn over more evenly. When the stirring plate 10 rotates smoothly, the staff opens the vacuum box 5, and the vacuum box 5 extracts the outside air, so that the air passes through the gas passage of the auger sleeve 21 and the gas passage in the rotating sleeve 11 to the cavities of all the stirring plates 10, and is discharged from the air holes on the stirring plates 10. Out into the material, thereby increasing the oxygen content in the material and improving the efficiency of aerobic fermentation. As the fermentation time gradually increases, the water content of the material gradually decreases, the solid gradually disperses and is further mixed with the liquid, and the volume of the material gradually decreases. When the specified fermentation time is reached, the solid is completely powdered, and the water evaporates further and decreases. After the staff observes that the appearance and color of the material meet the standards, the staff opens the discharge port of the tank body and transports the fermented material to the storage workshop by a transport vehicle. The staff turns off the motor 4 and the vacuum box 5 to complete the entire fermentation process of the material. After that, the staff opens the feed port again and fills the material into the tank body, and repeats the above actions to ferment the material.

[0024] In the process of gradually decreasing the water content of the material, the solid material gradually decomposes, and the dispersed solid is further mixed with the liquid. At this time, the fluidity of the material decreases, and the resistance of the stirring plate 10 gradually increases. The increased resistance drives the stirring plate 10 to overcome the torsion of the elastic member 9 and deflect, and the stirring plate 10 gradually changes from a vertical state to an inclined state. The stirring plate 10 guides the material, expands the flow range of the material in the vertical direction, and accelerates the mixing speed between materials at different heights, thereby making the stirring more uniform. While increasing the stirring effect, it reduces the influence of stratification caused by the gradual viscosity of the material on the fermentation rate.

[0025] As the stirring plate 10 gradually tilts, the elastic member 9 gradually accumulates force, and the stirring plate 10 drives the connecting piece 31 to rotate synchronously through the rotating shaft 8. As the stirring continues, the stirring plate 10 generates extrusion force by rotating and continuously pushes the material toward the crushing plate 22, so that the material passes through the crushing plate 22. The protrusions on the crushing plate 22 rub the material, and at the same time, the gap between the stirring plate 10 and the crushing plate 22 shears the material, so that the material is gradually broken into smaller particles. When the stirring plate 10 gradually tilts to the set maximum angle, the connecting piece 31 and the spiral piece 7 contact each other and are tightly combined to form an auger structure with material conveying function. Under the synergistic effect of the auger structure and the feed pipeline composed of the auger sleeve 21 and the rotating sleeve 11, the material in the feed pipeline is pushed upward by the auger structure and discharged from the upper side of the feed pipeline. The material discharged from the upper side of the feed pipeline is mixed with the material in the tank body 2. The material at the bottom of the tank body 2 enters the feed pipeline composed of the auger sleeve 21 and the rotating sleeve 11 under the action of the auger structure and is pushed upward, completing the up and down circulation of the material in the tank body 2, reducing the stratification effect of the material caused by the reduction of water content, ensuring the uniformity and stability of the material during the fermentation process, and improving the fermentation quality of the material.

[0026] In the middle stage of material fermentation, the material generates too much heat during fermentation, and excessive heat accumulation causes overheating in the tank 2. The high temperature in the tank reduces the aerobic fermentation efficiency of the material, affecting the stability of the fermentation process and the product quality.

[0027] Embodiment 2: Based on embodiment 1, Figure 2 , Figure 3 , Figure 7 , Figure 8 and Fig.13As shown, it also includes: a transfer box 41, which is fixedly connected to the base 1, and an input pipe 42 is fixedly connected and connected between the transfer box 41 and the tank body 2. The connecting position of the input pipe 42 and the tank body 2 is located at the upper part of the tank body 2. A one-way valve is arranged on the input pipe 42. A heat collecting block is installed in the transfer box 41. The heat collecting block is made of alumina ceramics. The heat collecting block is a cylinder. The heat collecting block is provided with circumferentially distributed through holes. The aperture of the through holes on the heat collecting block gradually increases along the axis of the heat collecting block toward the outside. The heat collecting block is used to cool down the high-temperature gas in the tank body 2 and store heat, and slowly release heat when needed. The transfer box 41 has The heat insulation layer reduces the heat loss in the transfer box 41. The transfer box 41 and the exhaust box 5 are fixedly connected and communicated with an output pipe 43. The output pipe 43 completely wraps the side of the heat collecting block close to the output pipe 43, so that the output pipe 43 is communicated with the through hole of the heat collecting block. The output pipe 43 and the through hole of the heat collecting block form a gas passage. The output pipe 43 is rotatably connected with a connecting shaft 44, which passes through the output pipe 43. A sealing ring is arranged between the connecting shaft 44 and the output pipe 43 to ensure the sealing of the output pipe 43. The connecting shaft 44 is fixedly connected with a turbine 45; a driving component is arranged in the base 1, and is used to drive the turbine 45 to rotate.

[0028] like Figure 2 , Figure 3 , Figure 7-Figure 9 As shown, the driving assembly includes: a first gear 51, fixedly connected to the main shaft 6; a friction wheel 52, rotatably connected to the base 1, the first gear 51 drives the friction wheel 52 through a transmission gear, the number of teeth on the first gear 51 is greater than the number of teeth on the transmission gear on the friction wheel 52, a mounting frame is fixedly connected to the vacuum box 5, the mounting frame on the vacuum box 5 is slidably connected to a U-shaped frame 53, the U-shaped frame 53 is rotatably connected to a cylindrical wheel 54, the outer side of the friction wheel 52 and the circumferential side of the cylindrical wheel 54 are both made of rubber, In order to increase the friction force between the friction wheel 52 and the cylindrical wheel 54, the cylindrical wheel 54 and the connecting shaft 44 are transmitted through a bevel gear set, the bevel gear close to the cylindrical wheel 54 in the bevel gear set is fixedly connected to the cylindrical wheel 54, the bevel gear close to the connecting shaft 44 in the bevel gear set is spline-connected to the connecting shaft 44, the bevel gear close to the connecting shaft 44 in the bevel gear set is fixedly connected to the U-shaped frame 53, and the friction wheel 52 is used to drive the cylindrical wheel 54 to rotate; a control component is arranged on the main shaft 6, and is used to control the rotation of the cylindrical wheel 54.

[0029] like Figure 5 , Figure 8-Figure 12As shown, the control component includes: a transmission sleeve 61, which is rotatably connected to the main shaft 6, and a first limiting groove 611 is arranged on the transmission sleeve 61. The first limiting groove 611 consists of a first straight groove 6111, a first rotating groove 6112, a second straight groove 6113, a second rotating groove 6114 and a third straight groove 6115. The transmission sleeve 61 is fixedly connected with a cam 62, and the cam 62 initially contacts with the right side of the U-shaped frame 53. At this time, the cylindrical wheel 54 is located farthest from the friction wheel 52, and the cam 62 is used to push the U-shaped frame 53 to move; a detection component is arranged on the main shaft 6, and is used to detect the height of the material in the tank body 2 and control the rotation of the cam 62.

[0030] like Figure 2 , Figure 5 and Fig. 9 As shown, the detection component includes: a float 71, which is slidably connected to the main shaft 6. A fixed groove is provided on the main shaft 6. The float 71 is located in the fixed groove on the main shaft 6 and slides. The fixed groove on the main shaft 6 is used to limit the float 71. The fixed groove on the main shaft 6 is connected to the tank body 2, so that the liquid in the tank body 2 can enter the fixed groove on the main shaft 6, and the float 71 is pushed upward by the liquid. The particle size of the upper solid material in the tank body 2 is smaller than the opening of the fixed groove on the main shaft 6. The fixed groove of the main shaft 6 is located on the upper side of the main shaft 6 and is used to limit the float 71. The float 71 is fixedly connected to a transmission frame 72. The transmission frame 72 is composed of a round rod and a round plate. A protrusion is provided on the round plate of the transmission frame 72. The protrusion on the round plate of the transmission frame 72 is located in the first limiting groove 611 of the transmission sleeve 61 and slides, which is used to detect the volume change of the material during the fermentation process through the float 71, and then switch the rotation state of the turbine 45 according to the volume change of the material.

[0031] When the staff is filling the tank with materials, the materials gradually push the float 71 located at the bottom of the fixed groove on the main shaft 6 to move upward and make the float 71 flush with the liquid surface of the materials. In the process of the material volume gradually decreasing, the float 71 gradually drops. At this time, the temperature in the tank 2 is too high, and the float 71 drives the transmission frame 72 to move downward. The protrusion on the transmission frame 72 slides in the first straight groove 6111. After the protrusion on the transmission frame 72 passes through the connection between the first straight groove 6111 and the first rotating groove 6112, the transmission frame 72 moves downward and drives the transmission sleeve 61 to rotate clockwise through the protrusion on the transmission frame 72 (the following directions are all based on Fig. 9Taking the top view as an example), the transmission sleeve 61 drives the cam 62 to rotate clockwise, the cam 62 rotates clockwise and pushes the U-shaped frame 53 to move leftward, the cam 62 stops rotating after rotating 180° clockwise, the U-shaped frame 53 drives the cylindrical wheel 54 and the bevel gear in the bevel gear set close to the connecting shaft 44 to move leftward, and then the cylindrical wheel 54 contacts the friction wheel 52 (the motor 4 drives the main shaft 6 to rotate, the main shaft 6 drives the first gear 51 to rotate, and the first gear 51 drives the friction wheel 52 to rotate through the transmission gear). When the cylindrical wheel 54 contacts the friction wheel 52, the cam 6 2 pushes the U-shaped frame 53 to reach the maximum moving distance, and the protrusion on the transmission frame 72 is located at the connection between the first rotating groove 6112 and the second straight groove 6113. At this time, the inside of the tank is in the middle stage of fermentation, and the fermentation heat generation is high. Therefore, the gas in the tank is mainly high-temperature gas. The friction wheel 52 drives the cylindrical wheel 54 to rotate, and the cylindrical wheel 54 drives the connecting shaft 44 to rotate through the bevel gear set. The connecting shaft 44 drives the turbine 45 to rotate, and the turbine 45 rotates and extracts the gas in the transfer box 41. When the gas in the transfer box 41 is too little, the low pressure triggers and opens the one-way valve on the input pipe 42. The high-temperature gas in the tank body 2 enters the transfer box 41 through the input pipe 42, and the high-temperature gas in the tank body 2 passes through the transfer box 41 and is extracted to the output pipe 43 by the turbine 45. When the high-temperature gas in the tank body 2 passes through the heat collecting block in the transfer box 41, since the temperature of the heat collecting block is lower than that of the high-temperature gas in the tank body 2, the heat collecting block gradually absorbs the temperature of the high-temperature gas flowing through, and the high-temperature gas entering the transfer box 41 gradually cools down and enters the exhaust box 5 through the output pipe 43. The gas in the transfer box 41 that has been cooled down by the heat collecting block is mixed with the normal-temperature air in the exhaust box 5 (exhaust The air box 5 is always in working state and draws external air). The mixed gas in the air box 5 enters the cavity of the stirring plate 10 through the gas passage in the rotating sleeve 11 and the auger sleeve 21, and is ejected from the air holes of the stirring plate 10 back into the tank body 2, so that the temperature of the high-temperature gas in the tank body 2 is reduced, reducing the influence of the excessively high gas temperature in the tank body 2 on the fermentation efficiency of the material, and reducing the influence on the stability of the fermentation process and the product quality. In the above process, the turbine 45 continues to rotate and draws air in the tank body 2, and the float 71 continues to descend with the fermentation of the material.

[0032] In the process of gradually decreasing the volume of the material, after the protrusion on the transmission frame 72 passes through the connection between the second straight groove 6113 and the second rotating groove 6114, the temperature of the gas in the tank body 2 gradually decreases, the transmission frame 72 moves downward and drives the transmission sleeve 61 to rotate counterclockwise through the protrusion on the transmission frame 72, the transmission sleeve 61 drives the cam 62 to rotate counterclockwise, the cam 62 rotates counterclockwise and pushes the U-shaped frame 53 to move right, the cam 62 stops rotating after rotating 180° counterclockwise, the U-shaped frame 53 drives the cylindrical wheel 54 and the bevel gear in the bevel gear group close to the connecting shaft 44 to move right, so that the cylindrical wheel 54 is out of contact with the friction wheel 52, and when the cam 62 returns to its initial state, the transmission frame 72 is The protrusion is located at the connection between the second rotating groove 6114 and the third straight groove 6115, thereby stopping the above-mentioned air pumping action. At this time, the heat accumulation block in the transfer box 41 is in a high temperature state and stores a large amount of heat. Since the turbine 45 stops rotating, negative pressure is no longer generated in the transfer box 41, and the one-way valve on the input pipe 42 is closed, so that the heat accumulation block in the transfer box 41 remains in a closed state, completing the cooling of the gas in the tank body and storing the temperature in the heat accumulation block in the transfer box 41. When the specified fermentation time is reached, the staff opens the discharge port to release the material after fermentation, and the float 71 continues to gradually descend until the material is discharged, and the protrusion on the transmission frame 72 moves to the lower end of the third straight groove 6115 and stops moving.

[0033] In the later stage of material fermentation, the material fermentation heat generation is insufficient, and excessive reduction of heat in tank body 2 will slow down the fermentation rate. Excessive reduction of heat will reduce the aerobic fermentation efficiency of the material in the tank, affecting the stability of the fermentation process and product quality.

The base 1 is composed of four rotating grooves 6124 and a sixth straight groove 6125. The third straight groove 6115 on the first limiting groove 611 is connected to the fourth straight groove 6121 on the second limiting groove 612. The base 1 is fixedly connected with a transmission tube 82, and the transmission tube 82 is filled with liquid. The extrusion column 81 is slidably connected with the transmission tube 82. The extrusion column 81 slides in the transmission tube 82. The end of the transmission tube 82 close to the vacuum box 5 is slidably connected with the first rack 83. The vacuum box 5 is provided with a valve 84. The valve stem of the valve 84 is fixedly connected with the second gear 85. The first rack 83 and the second gear 85 are meshed.

[0035] like Figure 7 , Figure 8 , Fig.10 , Fig.13 and Fig.14 As shown, the end of the transmission pipe 82 away from the exhaust box 5 is slidably connected to the second rack 91, the transfer box 41 is rotatably connected to the third gear 92, the second rack 91 and the third gear 92 are meshed, the third gear 92 is provided with a plurality of sliding grooves 93 distributed circumferentially, the sliding grooves 93 are inclined grooves, the transfer box 41 is provided with a plurality of connecting frames, the transfer box 41 is slidably connected to the telescopic sleeve 94 through the connecting frames, the connecting frame on the transfer box 41 has the same number of straight grooves as the telescopic sleeve 94, and the telescopic sleeve 94 is connected between adjacent straight grooves and adjacent straight grooves. The telescopic sleeve 94 slides under the joint action of the inclined groove, the number of the telescopic sleeves 94 is consistent with the number of the sliding grooves 93, a transmission hose is fixedly connected between the telescopic sleeve 94 and the input pipe 42, the transmission hose is a bellows and can be extended and retracted according to the movement of the telescopic sleeve 94, the telescopic sleeve 94 is tightly attached to the heat accumulation block in the transfer box 41, the telescopic sleeve 94 and the through holes on the heat accumulation block form a gas passage, the transmission hose between the telescopic sleeve 94 and the input pipe 42 is used to connect the telescopic sleeve 94 and the input pipe 42, and the sliding groove 93 is used to control the movement of adjacent telescopic sleeves 94.

[0036] As the volume of the material gradually decreases, the protrusion on the transmission frame 72 enters the fourth straight groove 6121 from the third straight groove 6115 and slides downward along the fourth straight groove 6121. The gas temperature in the tank body 2 tends to room temperature, and the material in the tank body 2 enters the late fermentation stage. After the protrusion on the transmission frame 72 passes through the connection between the fourth straight groove 6121 and the third rotating groove 6122, the transmission frame 72 contacts the extrusion column 81, and then the transmission frame 72 moves downward and pushes the extrusion column 81 to move downward. The transmission frame 72 moves downward and drives the transmission sleeve 61 to rotate clockwise through the protrusion on the transmission frame 72. The cam 61 drives the cam 62 to rotate clockwise, and the cylindrical wheel 54 contacts the friction wheel 52 again. When the cylindrical wheel 54 contacts the friction wheel 52 again, the protrusion on the transmission frame 72 is located at the connection between the third rotating groove 6122 and the fifth straight groove 6123. The cylindrical wheel 54 drives the turbine 45 to rotate through the connecting shaft 44, and the air pumping action continues. The transmission frame 72 pushes the extrusion column 81 to move downward, the extrusion column 81 pushes the liquid in the transmission pipe 82 and drives the first rack 83 to move upward, and the extrusion column 81 pushes the liquid in the transmission pipe 82 and drives the second rack 91 to move rightward (herein, Fig.10For example, the turbine 45 rotates and extracts the gas in the transfer box 41. When the gas in the transfer box 41 is too little, the low pressure triggers and opens the one-way valve on the input pipe 42, and the low-temperature gas in the tank body 2 enters the transfer box 41 through the input pipe 42. The low-temperature gas in the tank body 2 passes through the transfer box 41 and is extracted to the output pipe 43 by the turbine 45. When the low-temperature gas in the tank body 2 passes through the heat accumulation block in the transfer box 41, since the temperature of the heat accumulation block is higher than that of the low-temperature gas in the tank body 2, the heat stored in the heat accumulation block is gradually released and the temperature of the low-temperature gas in the transfer box 41 is increased. The low-temperature gas in the transfer box 41 gradually heats up and enters the vacuum box 5 through the output pipe 43. The gas in the transfer box 41 heated by the heat collecting block is mixed with the air in the vacuum box 5. The mixed gas in the vacuum box 5 enters the cavity of the stirring plate 10 through the gas channels in the rotating sleeve 11 and the auger sleeve 21, and is ejected from the air holes of the stirring plate 10 back into the tank body 2, thereby heating the material in the tank body 2 to supplement and increase the temperature in the tank body, thereby reducing the influence of the extended fermentation time and poor fermentation quality due to low heat production in the late fermentation period.

[0037] As the volume of the material gradually decreases, after the protrusion on the transmission frame 72 passes through the connection between the fifth straight groove 6123 and the fourth rotating groove 6124, the temperature in the tank body 2 gradually increases, and the transmission frame 72 moves downward and drives the transmission sleeve 61 to rotate counterclockwise through the protrusion on the transmission frame 72. The transmission sleeve 61 drives the cam 62 to rotate counterclockwise and makes the cylindrical wheel 54 and the friction wheel 52 disengage from contact again. When the cam 62 returns to its initial state, the protrusion on the transmission frame 72 is located at the connection between the fourth rotating groove 6124 and the sixth straight groove 6125, thereby stopping the above-mentioned vacuum action. At this time, the heat accumulation block in the transfer box 41 is at room temperature.

[0038] In the process that the liquid in the transmission tube 82 drives the first rack 83 to move, the first rack 83 moves upward and drives the second gear 85 to rotate counterclockwise (in degrees). Fig.10 For example, from front to back), the second gear 85 drives the valve stem of the valve 84 to rotate counterclockwise, the valve 84 is gradually closed, the vacuum box 5 gradually reduces the amount of air extracted from the outside gas, the content of the outside air in the vacuum box 5 is gradually reduced, the tank body 2 and the vacuum box 5 form a closed loop through the input pipe 42 and the output pipe 43, the temperature in the tank body 2 gradually rises and the speed of the later fermentation of the material is increased, and the later fermentation of the material is completed.

[0039] In the process of the liquid in the transmission pipe 82 driving the second rack 91 to move, the second rack 91 drives the third gear 92 to rotate, the third gear 92 drives the sliding groove 93 to rotate, the rotation of the sliding groove 93 drives the telescopic sleeve 94 to move, the gas in the input pipe 42 enters the telescopic sleeve 94 through the transmission hose, the gas in the telescopic sleeve 94 passes through the through hole of the heat coagulation block in the transfer box 41 and then enters the output pipe 43, when the gas in the telescopic sleeve 94 passes through the through hole of the heat coagulation block in the transfer box 41, the heat coagulation block in the transfer box 41 heats the gas flowing through, as the heat coagulation block in the transfer box 41 gradually releases heat, the temperature of the heat coagulation block in the transfer box 41 gradually decreases, and the transfer box The efficiency of the heat block 41 in heating the low-temperature gas in the tank body 2 gradually decreases, and the telescopic sleeve 94 gradually expands. The movement of the telescopic sleeve 94 changes the connection area between the telescopic sleeve 94 and the through hole on the heat block, thereby extending the flow time of the low-temperature gas in the tank body 2 in the heat block in the transfer box 41, so that the low-temperature gas in the tank body 2 is heated more evenly, thereby completing the heating of the low-temperature gas in the tank body, and promoting the fermentation speed of the material. When the specified fermentation time is reached, the staff opens the discharge port to release the fermented material and completes the subsequent conveying action. At this time, the protrusion on the transmission frame 72 reaches the bottom of the sixth straight groove 6125, and the above operation process is repeated to continue the organic fertilizer fermentation.
