Description

Technical Field

[0001] This utility model relates to the field of soil conditioner preparation apparatus, and more particularly to a paddy field soil conditioner preparation apparatus. Background Technology

[0002] Paddy soil conditioner is a key material used to improve soil fertility, structure, and microbial activity in paddy fields, and to promote healthy rice growth. One of its core preparation processes involves the efficient and thorough aerobic fermentation of organic materials (such as crop straw, livestock manure, and mushroom residue). Through this fermentation process, pathogens and weed seeds are effectively killed, harmful substances in the organic matter are degraded, and they are transformed into stable humus and easily absorbed nutrients for crops.

[0003] Currently, fermentation devices used in soil conditioner production mainly take the following forms: open composting fermentation tanks, trough-type turning fermentation systems, and intermittent fermentation tanks. In actual large-scale production applications, these devices have gradually revealed numerous technical shortcomings, making it difficult to meet the demands of modern agriculture for continuous, stable, and controllable production of high-quality soil conditioners.

[0004] First, existing fermentation equipment generally suffers from poor controllability of the fermentation process. Open composting and trough fermentation are greatly affected by ambient temperature and weather. In low temperatures or during the rainy season, fermentation efficiency drops sharply, the cycle is significantly prolonged, and fermentation may even fail. At the same time, it is difficult to accurately monitor and automatically control the internal temperature and oxygen concentration, which can easily lead to anaerobic environments, produce foul-smelling gases, cause environmental pollution, and result in unstable fermentation quality.

[0005] Secondly, low fermentation uniformity and efficiency are another major technical bottleneck. While traditional trough-type compost turners can perform some turning, their effective range is limited, making it difficult to reach the core area of ​​the fermentation pile. This easily leads to uneven fermentation, creating "dead zones" where some materials are over-fermented while others remain under-fermented. This unevenness directly affects the consistency of the final improver product's quality. Furthermore, the intermittent operation mode (i.e., the next batch can only begin after the entire process of feeding, fermenting, and discharging of one batch of material is complete) results in low production efficiency, preventing continuous material processing and limiting production capacity.

[0006] Therefore, there is an urgent need for a new type of fermentation preparation device that can achieve continuous operation, automated control, precise regulation of fermentation environment parameters, and ensure uniform, efficient and stable fermentation of materials, so as to overcome the shortcomings of existing technologies and meet the needs of modern, large-scale and high-quality production of paddy field soil conditioners. Utility Model Content

[0007] The purpose of this invention is to provide a device for preparing paddy soil conditioner, thereby solving the problems of existing devices mentioned in the background section.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] This utility model discloses a preparation device for paddy field soil conditioner, comprising a support frame. A primary treatment chamber, a secondary treatment chamber, and a tertiary treatment chamber are sequentially arranged from top to bottom on the support frame. A feeding mechanism for conveying materials to the primary treatment chamber is provided on one side of the support frame. A feeding partition assembly is provided at the connection between the top of the primary treatment chamber and the feeding mechanism. The primary, secondary, and tertiary treatment chambers have identical main structures, each comprising a second mounting shell, a telescopic outer shell, a connecting shell, and a first mounting shell sequentially connected from top to bottom. A material dropping mechanism is provided inside the first mounting shell, and a material turning mechanism is provided above the material dropping mechanism. The upper part of the secondary treatment chamber is connected to the first mounting shell of the primary treatment chamber via the connecting shell, and the upper part of the tertiary treatment chamber is connected to the first mounting shell of the secondary treatment chamber via the connecting shell.

[0010] Furthermore, the cross-section of the second mounting shell is set to be square.

[0011] Furthermore, the material feeding mechanism includes several material feeding plates, the two sides of which are connected to the second mounting shell via connecting shafts. When the several material feeding plates rotate to a horizontal position, they block the second mounting shell. A linkage component is provided between the several material feeding plates, and the linkage component is driven by a first driving component.

[0012] Furthermore, the linkage component includes a connecting plate disposed at the exposed end of the connecting shaft, and several connecting plates are connected together by a linkage rod, with the connecting shaft located in the middle connected to the output shaft of the first driving member.

[0013] Furthermore, one side of the connecting shell has a square cross-section, and the other side of the connecting shell has a circular cross-section.

[0014] Furthermore, the telescopic outer shell includes a telescopic shell, and fixed shells are provided on both the upper and lower sides of the telescopic shell. A second driving member for driving the telescopic shell to expand or retract is provided on the outer side of the fixed shell.

[0015] Furthermore, the material turning mechanism includes several material turning components, and the first mounting shell is provided with a drive component for driving the several material turning components to work.

[0016] Furthermore, the material turning assembly includes a stirring rod, with spiral blades provided on the outer wall of the stirring rod, a bottom stirring rod provided at the bottom of the stirring rod, stirring shovels provided on both sides of the bottom stirring rod, and an auxiliary stirring rod provided between the two stirring shovels.

[0017] Furthermore, the drive assembly includes a lower gear ring and an upper gear ring disposed on the outside of the first mounting housing. A plurality of first gears are meshed between the lower gear ring and the upper gear ring. The central shaft of the first gear extends to the inside of the first mounting housing and is connected to a first bevel gear. A second bevel gear that meshes with the first bevel gear is disposed at the top of the stirring rod. An outer gear ring is disposed on the lower gear ring. A second gear is meshed on one side of the outer gear ring. A third drive member for driving the second gear to rotate is disposed on one side of the second gear.

[0018] Furthermore, the feed partition assembly includes a housing disposed on the top of the primary processing chamber, a partition door disposed inside the housing, and a fourth driving member disposed on one side of the partition door for driving the partition door to move.

[0019] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0020] This invention features a unique tower-like layered structure consisting of a primary, secondary, and tertiary treatment chamber. Combined with an internal turning mechanism, this ensures thorough mixing and turning of the materials within the treatment chambers, completely eliminating fermentation "dead zones." This dynamic and continuous turning method guarantees that all materials undergo uniform and sufficient aerobic fermentation, resulting in products with consistent maturity. This ensures high uniformity and consistent quality of the fermented products, significantly improving the final product quality of the paddy field soil conditioner. Furthermore, this invention can operate continuously. When material from the upper layer is pushed into the lower layer, new material is immediately added to the top, creating a continuous feeding and discharging cycle. This breaks through the production capacity bottleneck of traditional intermittent fermentation, improves work efficiency, and meets the needs of modern agriculture for large-scale, continuous production of soil conditioners.

[0031] like Figure 1-8As shown, a device for preparing a paddy field soil conditioner includes a support frame 2. From top to bottom, a primary treatment chamber 3, a secondary treatment chamber 4, and a tertiary treatment chamber 5 are sequentially connected above the support frame 2. A feeding mechanism 1 for conveying materials to the primary treatment chamber 3 is provided on one side of the support frame 2. The feeding mechanism 1 can be a screw conveyor. A feeding partition assembly 6 is provided at the connection between the top of the primary treatment chamber 3 and the feeding mechanism 1. The primary treatment chamber 3 is a preheating layer: PLC controls the introduction of preheated air into this layer, and the turning mechanism operates intermittently, causing the material to heat up rapidly. The secondary treatment... The primary processing chamber 4 is the high-temperature composting layer: This is the core layer, where the temperature is precisely controlled by the aeration and cooling system. The turning mechanism operates at the highest frequency, ensuring uniform composting of the material and killing pathogens, with the longest residence time. The tertiary processing chamber 5 is the cooling and stabilization layer for post-fermentation and discharge: Heating is stopped, and room-temperature air is introduced. The turning mechanism continues to work, and the material temperature gradually decreases. The material stabilizes in this layer, and microbial agents can be inoculated here through a humidification system before being discharged from the bottom. This device can operate continuously: when material from the first layer is pushed into the second layer, new material is immediately added from the top, and this cycle is repeated to achieve continuous feeding and discharging. Specifically, the insulation structure of the primary processing chamber 3, the secondary processing chamber 4, and the tertiary processing chamber 5, as well as the air supply and exhaust structures of each processing chamber, are all based on existing technologies and will not be elaborated here. Each processing layer integrates temperature sensors, oxygen concentration sensors, and an automated control system, enabling real-time monitoring and precise adjustment of key parameters such as internal fermentation temperature and oxygen content. Through a controllable ventilation and spraying system, the material is always kept in an optimal aerobic fermentation environment.

[0032] The primary processing chamber 3, the secondary processing chamber 4, and the tertiary processing chamber 5 have the same main structure, each including a second mounting shell 17, a telescopic outer shell, a connecting shell 13, and a first mounting shell 7 connected sequentially from top to bottom. A material dropping mechanism is provided inside the first mounting shell 7, and a material turning mechanism is provided above the material dropping mechanism. The upper part of the secondary processing chamber 4 is connected to the first mounting shell 7 of the primary processing chamber 3 through the connecting shell 13, and the upper part of the tertiary processing chamber 5 is connected to the first mounting shell 7 of the secondary processing chamber 4 through the connecting shell 13.

[0033] The cross-section of the second mounting shell 17 is set as a square.

[0034] like Figure 5As shown, the material feeding mechanism includes several material feeding plates 8. The two sides of the material feeding plates 8 are connected to the second mounting shell 17 via connecting shafts 9. The other two sides of the material feeding plates 8 are respectively provided with bosses on the top and bottom. When the several material feeding plates 8 rotate to the horizontal position, the bosses of two adjacent material feeding plates 8 overlap together, sealing the second mounting shell 17. A linkage assembly is provided between the several material feeding plates 8. The linkage assembly is driven by a first driving member 12. The linkage assembly includes a connecting plate 10 installed on the exposed end of the connecting shaft 9. The other end of the connecting plate 10 is hinged to a linkage rod 11. The several connecting plates 10 are connected together via the linkage rod 11. The connecting shaft 9 located in the middle is connected to the output shaft of the first driving member 12. The first driving member 12 is a motor.

[0035] In use, the first driving component 12 drives the connecting shaft 9 located in the middle to rotate. At the same time, the connecting shaft 9 rotates, and the other connecting shafts 9 rotate together through the linkage rod 11, so that several dropping plates 8 rotate at the same time. The material falls down through the gap between adjacent dropping plates 8 to achieve material dropping.

[0036] One side of the connecting shell 13 has a square cross-section, and the other side of the connecting shell 13 has a circular cross-section. By designing different shapes at both ends of the connecting shell 13, it is easy to connect with the first mounting shell 7 and other structures. The connecting shell 13 located below the first mounting shell 7 also has the function of guiding materials to fall smoothly through its structural changes.

[0037] like Figure 3-4 As shown, the telescopic housing includes a telescopic shell 15, and fixed shells 14 are connected to both the upper and lower sides of the telescopic shell 15. A second driving member 16 for driving the telescopic shell 15 to expand or contract is provided on the outer side of the fixed shell 14. The fixed end of the second driving member 16 is mounted on the outer wall of the connecting shell 13 located below the fixed shell 14 through a bracket. The working end of the second driving member 16 is connected to the outer wall of the fixed shell 14 above through a bracket. The second driving member 16 can be an existing component such as a hydraulic cylinder or a pneumatic cylinder.

[0038] During material feeding, the material feeding plate 8 requires space to flip. At this time, the second driving component 16 drives the telescopic shell 15 to unfold upwards, thereby causing the second mounting shell 17 and its internal flipping mechanism to move upwards, moving the flipping mechanism away from the material feeding plate 8 and making room for the material feeding plate 8 to flip. When material feeding is not needed, the second driving component 16 drives the telescopic shell 15 to retract downwards, thereby causing the second mounting shell 17 and its internal flipping mechanism to move downwards, reducing the gap between the flipping mechanism and the material feeding plate 8 and reaching the most suitable position, facilitating the full flipping of the material above the material feeding plate 8.

[0039] The material turning mechanism includes several material turning components, and the first mounting shell 7 is provided with a drive component for driving the several material turning components to work. Each material turning component includes a stirring rod 25, with spiral blades 27 connected to the outer wall of the stirring rod 25, and a bottom stirring rod 28 connected to the bottom of the stirring rod 25, such as... Figure 7 As shown, both sides of the bottom stirring rod 28 are connected to stirring shovels, and an auxiliary stirring rod 29 is provided between the two stirring shovels; the bottom stirring rod 28 and the auxiliary stirring rod 29 work together to fully turn the material at the bottom, and the spiral blades 27 can drive the material upward and throw it, so that the material is fully turned.

[0040] like Figure 6 As shown, the drive assembly includes a lower gear ring 18 and an upper gear ring 19 rotatably mounted on the outside of the first mounting housing 7. Four first gears 20 are meshed between the lower gear ring 18 and the upper gear ring 19, as shown... Figure 4 As shown, the central axis of the first gear 20 extends to the inner side of the first mounting shell 7 and is connected to the first bevel gear 24. The top of the stirring rod 25 is equipped with a second bevel gear 26 that meshes with the first bevel gear 24. The top surface of the lower gear ring 18 is connected to an outer gear ring 21. One side of the outer gear ring 21 is meshed with a second gear 23. One side of the second gear 23 is provided with a third driving member 22 for driving the second gear 23 to rotate. Specifically, the third driving member 22 is mounted on a mounting plate located above the second mounting shell 17. The third driving member 22 can be a motor.

[0041] In use, the third drive component 22 drives the second gear 23 to rotate, the rotation of the second gear 23 drives the outer gear ring 21 to rotate, the rotation of the outer gear ring 21 drives the upper gear ring 19 to rotate, the rotation of the upper gear ring 19 drives the first gear 20 to rotate, the rotation of the first gear 20 drives the first bevel gear 24 to rotate, the rotation of the first gear 20 also drives the lower gear ring 18 to rotate, the rotation of the first bevel gear 24 drives the second bevel gear 26 to rotate, and the rotation of the second bevel gear 26 drives the stirring rod 25 to rotate, thus performing stirring and tumbling work.

[0042] like Figure 8 As shown, the feed isolation assembly 6 includes a housing 601 connected above the feed inlet at the top of the primary processing chamber 3. A partition door 603 is disposed inside the housing 601. A fourth driving component 602 for moving the partition door 603 is installed on one side of the partition door 603. The fourth driving component 602 can be a hydraulic cylinder or a pneumatic cylinder, etc. In use, when feeding is not required, the fourth driving component 602 moves the partition door 603 to the left, blocking the feed inlet; when feeding is required, the fourth driving component 602 moves the partition door 603 to the right, opening the feed inlet for easy feeding.

[0043] The working process of this utility model is as follows:

[0044] First, the raw materials for making soil conditioner are transported to the primary treatment chamber 3 using the feeding mechanism 1. The primary treatment chamber 3 is preheated by introducing preheated air, and the turning mechanism operates intermittently, causing the material to heat up rapidly. Then, the discharge mechanism at the bottom of the primary treatment chamber 3 opens, discharging the material into the secondary treatment chamber 4. High-temperature composting takes place in the secondary treatment chamber 4. During this process, the turning mechanism operates at the highest frequency to ensure uniform composting and kill pathogens, with the longest residence time. Afterward, the discharge mechanism at the bottom of the secondary treatment chamber 4 opens, discharging the material into the tertiary treatment chamber 5. The temperature in the tertiary treatment chamber 5 is cooled and stabilized, and room temperature air is introduced. The turning mechanism continues to operate, and the material temperature gradually decreases. The material stabilizes at this layer, and microbial agents can be inoculated at this layer. Finally, the discharge mechanism at the bottom of the tertiary treatment chamber 5 opens, discharging the material.
