Abstract
Description
Technical Field
[0001] This invention relates to a microbial inoculum addition mechanism and method for producing bio-organic fertilizer, belonging to the field of organic fertilizer production technology. Background Technology
[0002] In the production of bio-organic fertilizer, the addition of microbial strains is a key step that determines the fermentation effect and product quality of organic fertilizer. The microbial solution must be applied evenly and precisely to the surface of the organic fertilizer material, and it must be efficiently linked with the organic fertilizer transportation process to ensure the stability of subsequent fermentation processes.
[0003] Current methods for adding microbial inoculants in bio-organic fertilizer production lack specialized addition devices adapted to the organic fertilizer belt conveyor process, and generally suffer from the following technical defects: 1. The spray width of the microbial liquid spraying device cannot cover the entire conveying width of the organic fertilizer conveyor, and the sprayer layout lacks standardized design, easily leading to uneven addition of microbial liquid in some areas and insufficient addition in others, directly affecting the fermentation consistency of the bio-organic fertilizer; 2. The height of the microbial inoculant addition device is fixed, lacking a flexible height adjustment structure, making it impossible to adjust the distance between the sprayer and the material according to the particle size and conveying thickness of the organic fertilizer material, easily resulting in material rubbing against the sprayer and improper spraying range leading to expansion of the microbial liquid. 3. The bacterial liquid supply system and the organic fertilizer conveying device lack a coordinated adjustment mechanism. The supply rate cannot be flexibly adjusted according to the conveying rate of organic fertilizer and the conveying amount per unit area, resulting in uncontrolled bacterial liquid addition ratio, waste of bacterial strains or insufficient addition, affecting the fermentation effect of organic fertilizer; 4. Some bacterial strain addition devices and organic fertilizer conveying equipment are integrated into one design, which makes installation, disassembly and maintenance operations cumbersome and will affect the original operating rhythm of the conveying equipment, reducing production continuity; 5. The layout of bacterial liquid conveying pipeline is unreasonable, which is prone to leakage and blockage. Moreover, the disassembly and assembly of the injector is inconvenient, which increases the daily maintenance cost of the equipment and downtime due to failure.
[0004] To solve one of the above problems, there is an urgent need for a microbial inoculum addition mechanism for the production of bio-organic fertilizer. Summary of the Invention
[0005] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is: how to achieve uniform spraying of bacterial liquid and complete the initial mixing with organic fertilizer. The peristaltic pump can adjust the supply of bacterial liquid according to the delivery rate of organic fertilizer and the thickness of material to ensure the accurate addition ratio of bacterial liquid. To this end, a bacterial inoculum addition mechanism for the production of bio-organic fertilizer is provided.
[0006] The microbial inoculant addition mechanism for bio-organic fertilizer production of the present invention includes an organic fertilizer conveying device and a microbial liquid sprayer installed above the conveying path of the organic fertilizer conveying device. Its features include: a left mounting plate, a right mounting plate, and a mounting plate fixing beam. The two ends of the mounting plate fixing beam are respectively vertically connected to a left hollow connecting rod and a right hollow connecting rod. A vertical microbial liquid sprayer is installed along the length of the mounting plate fixing beam. Multiple sets of microbial liquid sprayers are installed at equal intervals on the mounting plate fixing beam. The left hollow connecting rod is connected to the left mounting plate via a first height adjustment mechanism, and the right hollow connecting rod is connected to the right mounting plate via a second height adjustment mechanism. The mounting plate fixing beam is positioned above the conveying path of the organic fertilizer conveying device, and there is a material passage gap between the bottom side of the microbial liquid sprayer and the upper belt of the organic fertilizer conveying device. The left and right mounting plates are respectively installed on both sides of the organic fertilizer conveying device.
[0007] Using the left and right mounting plates as the mounting base, the system is fixed to both sides of the organic fertilizer conveying device. The crossbeams fixed by the mounting plates serve as the carriers for the injectors. Multiple sets of bacterial liquid injectors are installed at equal intervals along the length of the crossbeams to achieve full coverage and uniform spraying of the conveying area. The modular assembly and reasonable installation layout do not affect the original operation of the conveying device. Relying on the coordinated cooperation of the double-sided height adjustment mechanism, the height of the material passage gap can be flexibly adjusted to ensure that the bacterial liquid injectors are always above the conveying path of the organic fertilizer conveying device, achieving uniform spraying of the bacterial liquid and completing the initial mixing with the organic fertilizer.
[0008] In any of the above embodiments, preferably, the first height adjustment mechanism includes a top plate A and a bottom plate A that are parallel to each other. The top plate A and the bottom plate A are both horizontally arranged and are respectively vertically installed at the top end and bottom end of the left mounting plate. A first screw that passes through the left hollow connecting rod is installed between the top plate A and the bottom plate A. A first slide rail that is parallel to the first screw is fixed on the outer surface of the left mounting plate. A first slider that slides in cooperation with the first slide rail is on the outer wall of the left hollow connecting rod. An upper nut A and a lower nut A are threadedly connected to the first screw. The upper nut A and the lower nut A are respectively located on the upper and lower sides of the left hollow connecting rod and are used to clamp and lock the left hollow connecting rod.
[0009] By rotating the upper nut A and lower nut A as needed, the hollow connecting rod on the left side can be adjusted to rise or fall relative to the first screw. The first slider and the first slide rail maintain a sliding fit, ensuring the stability of the mounting plate fixing beam. The mounting plate fixing beam provides stable support for the mounting plate fixing beam and the bacterial liquid sprayer.
[0010] The threaded adjustment method is simple to operate, enabling precise lifting and lowering of the left hollow connecting rod, thereby accurately adjusting the height of the corresponding side sprayer; the sliding cooperation between the slide rail and the slider limits the swaying of the connecting rod, ensuring the stability of the mounting plate fixing the crossbeam during lifting; the upper and lower nuts clamp and lock the position of the left hollow connecting rod, ensuring reliable fixation and eliminating the risk of loosening, providing stable support for the crossbeam and bacterial liquid sprayer; the overall structure is modularly designed, making assembly and maintenance convenient.
[0011] In any of the above embodiments, it is preferred that the left hollow connecting rod is a rectangular steel tube, and a through hole A is provided on the left hollow connecting rod for the first screw to pass through. This ensures structural strength while reducing weight. The structural characteristics of the rectangular steel tube effectively reduce the weight of the connecting rod itself while ensuring the structural strength and supporting stiffness of the connecting rod, thus reducing the load on the overall mechanism; the provision of a suitable through hole A allows for precise matching with the first screw, does not interfere with the height adjustment operation, and simplifies the manufacturing process.
[0012] In any of the above embodiments, preferably, the second height adjustment mechanism includes a top plate B and a bottom plate B that are parallel to each other. The top plate B and the bottom plate B are both horizontally arranged and are respectively vertically installed at the top end and bottom end of the right mounting plate. A second screw that passes through the right hollow connecting rod is installed between the top plate B and the bottom plate B. A second slide rail that is parallel to the second screw is fixed on the outer surface of the right mounting plate. A second slider that slides with the second slide rail is provided on the outer wall of the right hollow connecting rod. An upper nut B and a lower nut B are threadedly connected to the second screw. The upper nut B and the lower nut B are respectively located on the upper and lower sides of the right hollow connecting rod and are used to clamp and lock the right hollow connecting rod.
[0013] By rotating the upper nut B and the lower nut B as needed, the right hollow connecting rod can be adjusted to rise or fall relative to the second screw. The second slider and the second slide rail maintain a sliding fit, ensuring the stability of the left hollow connecting rod. The left hollow connecting rod provides stable support for the mounting plate fixing beam and the bacterial liquid sprayer.
[0014] It forms a symmetrical design with the first height adjustment mechanism, and the operation method is uniform, which makes it easy for the staff to adjust the height of the connecting rods on both sides at the same time, so as to ensure the levelness of the mounting plate fixing beam.
[0015] In any of the above embodiments, it is preferred that the right hollow connecting rod is a rectangular steel tube, and a through hole B is provided on the right hollow connecting rod for the second screw to pass through.
[0016] In any of the above embodiments, it is preferred that the bottom plate A at the bottom of the left mounting plate and the bottom plate B at the bottom of the right mounting plate are respectively mounted on the frame on both sides of the feed end of the organic fertilizer conveying device.
[0017] In any of the above embodiments, it is preferred that the mounting plate fixing beam is a rectangular steel pipe and the organic fertilizer conveying device is a belt conveyor.
[0018] In any of the above embodiments, it is preferred that each group of bacterial liquid injectors is fixed on the mounting plate beam by corresponding installation, the liquid inlet at the upper end of the bacterial liquid injector is interconnected by a connecting branch pipe, the bottom end of the bacterial liquid injector has an atomizing nozzle, the connecting branch pipe is connected to the bacterial liquid supply tank through the liquid supply main pipe, and a peristaltic pump is installed on the liquid supply main pipe.
[0019] The fixed clamp installation method makes it easy to disassemble, install, and fine-tune the position of the bacterial liquid injector, facilitating later maintenance and replacement. The design of the connecting branch pipes ensures synchronous and equal liquid supply to all injectors, guaranteeing the uniformity of bacterial liquid spraying from the pipeline level. The peristaltic pump can precisely adjust the liquid supply rate and volume, flexibly adjusting according to the organic fertilizer delivery rate and material thickness to ensure accurate bacterial liquid addition ratio. The bacterial liquid supply tank provides a continuous material source for bacterial liquid spraying, avoiding supply interruptions and improving operational continuity. The overall pipeline is designed in series, with a simple layout, reducing pipeline bends and lowering the risk of leakage and blockage.
[0020] The method for adding microbial inoculants for the production of bio-organic fertilizer is characterized by the following steps: Step 1, installing and fixing the device; Step 2, precisely adjusting the material passage gap; Step 3, checking the microbial liquid delivery pipeline; Step 4, starting the equipment in conjunction with the system; Step 5, adding the microbial liquid by spraying.
[0021] In any of the above schemes, the preferred method is that, in step 1, the device is installed and fixed, and the specific steps are as follows: the bottom plate A at the bottom of the left mounting plate and the bottom plate B at the bottom of the right mounting plate are respectively and firmly installed on the frame on both sides of the feed end of the organic fertilizer conveying device, so that the mounting plate fixing beam is directly above the conveying trajectory of the organic fertilizer conveying device, and the bacterial liquid sprayer faces the upper belt of the organic fertilizer conveying device, initially ensuring that there is a material passage gap between the bottom side of the bacterial liquid sprayer and the upper belt.
[0022] In step 2, the material passage gap is precisely adjusted by coordinating the first height adjustment mechanism and the second height adjustment mechanism to finely adjust the material passage gap between the bacterial liquid injector and the upper belt of the organic fertilizer conveying device to adapt to organic fertilizer materials of different particle sizes and thicknesses. After the adjustment is completed, the levelness and stability of the mounting plate fixing beam are checked to ensure that the material passage gap of all bacterial liquid injectors is uniform.
[0023] Step 3, the inspection of the bacterial liquid delivery pipeline, specifically involves the following steps: checking the amount of organic fertilizer bacterial liquid in the bacterial liquid supply tank to ensure that the storage capacity meets the addition requirements; sequentially checking the connection and sealing of the main supply pipe, connecting branch pipe and bacterial liquid injector to confirm that there is no leakage or blockage; and checking the operating status of the peristaltic pump to ensure that it can start and stop normally and adjust the supply rate.
[0024] Step 4 involves the coordinated start-up of the equipment. The specific steps are as follows: 1. Start the organic fertilizer conveying device to operate at a preset conveying rate to ensure that the organic fertilizer material can pass through the material passage gap below the bacterial liquid sprayer at a uniform speed; 2. Start the peristaltic pump to transport the bacterial liquid in the supply tank to the connecting branch pipe through the main supply pipe, and then distribute it to each group of equally spaced bacterial liquid sprayers through the connecting branch pipe. The peristaltic pump can adjust the supply volume of bacterial liquid according to the conveying rate of the organic fertilizer and the thickness of the material to ensure accurate bacterial liquid addition ratio.
[0025] Step 5: Adding bacterial solution by spraying. The specific steps are as follows: the bacterial solution is sprayed downwards synchronously by each group of bacterial solution sprayers and evenly applied to the surface of the organic fertilizer material on the upper belt of the organic fertilizer conveying device. Because the bacterial solution sprayers are installed at equal intervals on the fixed crossbeam of the mounting plate and the organic fertilizer is conveyed at a uniform speed, the bacterial solution is evenly added to the organic fertilizer material. The material continues to operate with the conveying device to complete the initial mixing of bacterial solution and organic fertilizer.
[0026] The equipment linkage speed matching requirements enable precise coordination between organic fertilizer delivery and bacterial solution supply, ensuring the accuracy of bacterial solution addition ratio and avoiding waste or insufficient addition; relying on structural advantages, the bacterial solution is evenly sprayed and initially mixed during delivery, improving the fusion effect between bacterial solution and organic fertilizer, laying the foundation for subsequent treatment.
[0027] Compared with the prior art, the present invention has the following beneficial effects:
[0028] The microbial inoculant addition mechanism for bio-organic fertilizer production described in this invention uses a left-side mounting plate and a right-side mounting plate as mounting bases, fixed on both sides of the organic fertilizer conveying device. A crossbeam fixed to the mounting plates serves as the carrier for the injectors. Multiple sets of microbial liquid injectors are installed at equal intervals along the length of the crossbeam, achieving full coverage and uniform spraying of the conveying area. The modular assembly and reasonable installation layout do not affect the original operation of the conveying device. Relying on the coordinated operation of the dual-sided height adjustment mechanism, the height of the material passage gap can be flexibly adjusted to ensure that the microbial liquid injectors are always above the conveying path of the organic fertilizer conveying device, achieving uniform spraying of the microbial liquid and completing the initial mixing with the organic fertilizer.
[0029] The microbial inoculant addition mechanism for bio-organic fertilizer production described in this invention features a simple threaded adjustment mechanism that allows for precise lifting and lowering of the left hollow connecting rod, thereby accurately adjusting the height of the corresponding side injector. The sliding cooperation between the slide rail and the slider limits the swaying of the connecting rod, ensuring the stability of the mounting plate fixing the crossbeam during lifting. The upper and lower nuts clamp and lock the mechanism, ensuring the reliable fixation of the left hollow connecting rod without the risk of loosening, providing stable support for the crossbeam and the microbial liquid injector. The overall structure is modularly designed, making assembly and maintenance convenient.
[0030] The method for adding microbial inoculants for the production of bio-organic fertilizer described in this invention involves starting a peristaltic pump, which delivers the microbial solution from the supply tank to the connecting branch pipe via the main supply pipe, and then distributes it to the microbial solution injectors set at equal intervals in each group via the connecting branch pipe. The peristaltic pump can adjust the supply volume of the microbial solution according to the delivery rate of the organic fertilizer and the thickness of the material to ensure accurate addition ratio of the microbial solution.

The left mounting plate 1 and the right mounting plate 2 are respectively installed on both sides of the organic fertilizer conveying device 7.
[0039] Using the left and right mounting plates as the mounting base, the system is fixed to both sides of the organic fertilizer conveying device. The crossbeams fixed by the mounting plates serve as the carriers for the injectors. Multiple sets of bacterial liquid injectors are installed at equal intervals along the length of the crossbeams to achieve full coverage and uniform spraying of the conveying area. The modular assembly and reasonable installation layout do not affect the original operation of the conveying device. Relying on the coordinated cooperation of the double-sided height adjustment mechanism, the height of the material passage gap can be flexibly adjusted to ensure that the bacterial liquid injector 6 is always above the conveying path of the organic fertilizer conveying device 7, achieving uniform spraying of the bacterial liquid and completing the initial mixing with the organic fertilizer.
[0040] Example 2, as Figure 1-3 As shown, the microbial inoculant addition mechanism for producing organic fertilizer includes an organic fertilizer conveying device 7 and a microbial liquid sprayer 6 installed above the conveying path of the organic fertilizer conveying device 7. It also includes a left mounting plate 1, a right mounting plate 2, and a mounting plate fixing beam 3. The two ends of the mounting plate fixing beam 3 are vertically connected to a left hollow connecting rod 4 and a right hollow connecting rod 5, respectively. Vertical microbial liquid sprayers 6 are installed along the length of the mounting plate fixing beam 3. Multiple sets of microbial liquid sprayers 6 are installed at equal intervals on the mounting plate fixing beam 3. The left hollow connecting rod 4 is connected to the left mounting plate 1 via a first height adjustment mechanism, and the right hollow connecting rod 5 is connected to the right mounting plate 2 via a second height adjustment mechanism. The mounting plate fixing beam 3 is positioned above the conveying path of the organic fertilizer conveying device 7, and there is a material passage gap between the bottom side of the microbial liquid sprayer 6 and the upper belt of the organic fertilizer conveying device 7. The left mounting plate 1 and the right mounting plate 2 are respectively installed on both sides of the organic fertilizer conveying device 7.
[0041] Furthermore, the first height adjustment mechanism includes a top plate A8 and a bottom plate A9 that are parallel to each other. The top plate A8 and the bottom plate A9 are both horizontally arranged and are respectively vertically installed at the top and bottom of the left mounting plate 1. A first screw 10 that passes through the left hollow connecting rod 4 is installed between the top plate A8 and the bottom plate A9. A first slide rail 11 that is parallel to the first screw 10 is fixed on the outer surface of the left mounting plate 1. A first slider 12 that slides in cooperation with the first slide rail 11 is on the outer wall of the left hollow connecting rod 4. An upper nut A13 and a lower nut A14 are threadedly connected to the first screw 10. The upper nut A13 and the lower nut A14 are respectively located on the upper and lower sides of the left hollow connecting rod 4 and are used to clamp and lock the left hollow connecting rod 4.
[0042] By rotating the upper nut A13 and the lower nut A14 as needed, the left hollow connecting rod 4 can be adjusted to rise or fall relative to the first screw 10. The first slider 12 and the first slide rail 11 maintain a sliding fit, ensuring the stability of the mounting plate fixing beam 3. The mounting plate fixing beam 3 provides stable support for the mounting plate fixing beam 3 and the bacterial liquid sprayer 6.
[0043] The threaded adjustment method is simple to operate, enabling precise lifting and lowering of the left hollow connecting rod, thereby accurately adjusting the height of the corresponding side sprayer; the sliding cooperation between the slide rail and the slider limits the swaying of the connecting rod, ensuring the stability of the mounting plate fixing the crossbeam during lifting; the upper and lower nuts clamp and lock the position of the left hollow connecting rod, ensuring reliable fixation and eliminating the risk of loosening, providing stable support for the crossbeam and bacterial liquid sprayer; the overall structure is modularly designed, making assembly and maintenance convenient.
[0044] Furthermore, the left hollow connecting rod 4 is a rectangular steel tube, and a through hole A is provided on the left hollow connecting rod 4 for the first screw 10 to pass through. This ensures structural strength while reducing weight. The structural characteristics of the rectangular steel tube effectively reduce the weight of the connecting rod itself, thus reducing the load on the overall mechanism, while ensuring the structural strength and supporting rigidity of the connecting rod. The appropriate through hole A allows for precise matching with the first screw, does not interfere with height adjustment operations, and simplifies the manufacturing process.
[0045] Furthermore, the second height adjustment mechanism includes a top plate B15 and a bottom plate B16 that are parallel to each other. The top plate B15 and the bottom plate B16 are both horizontally arranged and are respectively vertically installed at the top and bottom of the right mounting plate 2. A second screw 17 that passes through the right hollow connecting rod 5 is installed between the top plate B15 and the bottom plate B16. A second slide rail 18 that is parallel to the second screw 17 is fixed on the outer surface of the right mounting plate 2. A second slider 19 that slides in cooperation with the second slide rail 18 is provided on the outer wall of the right hollow connecting rod 5. An upper nut B20 and a lower nut B21 are threadedly connected to the second screw 17. The upper nut B20 and the lower nut B21 are respectively located on the upper and lower sides of the right hollow connecting rod 5 and are used to clamp and lock the right hollow connecting rod 5.
[0046] By rotating the upper nut B20 and the lower nut B21 as needed, the right hollow connecting rod 5 can be adjusted to rise or fall relative to the second screw 17, and the second slider 19 and the second slide rail 18 maintain a sliding fit, ensuring the stability of the left hollow connecting rod 4. The left hollow connecting rod 4 provides stable support for the mounting plate fixing beam 3 and the bacterial liquid sprayer 6.
[0047] It forms a symmetrical design with the first height adjustment mechanism, and the operation method is uniform, which makes it easy for the staff to adjust the height of the connecting rods on both sides at the same time, so as to ensure the levelness of the mounting plate fixing beam.
[0048] Furthermore, the right hollow connecting rod 5 is a rectangular steel tube, and a through hole B is provided on the right hollow connecting rod 5 for the second screw 17 to pass through.
[0049] Furthermore, the bottom plate A9 at the bottom of the left mounting plate 1 and the bottom plate B16 at the bottom of the right mounting plate 2 are respectively installed on the frame on both sides of the feed end of the organic fertilizer conveying device 7.
[0050] Furthermore, the mounting plate fixing beam 3 is a rectangular steel pipe, and the organic fertilizer conveying device 7 is a belt conveyor.
[0051] Furthermore, each set of bacterial liquid injectors 6 is mounted on the mounting plate fixing beam 3 via a corresponding 26. The liquid inlet at the upper end of the bacterial liquid injector 6 is interconnected via a connecting branch pipe 22. The bottom end of the bacterial liquid injector 6 has an atomizing nozzle. The connecting branch pipe 22 is connected to the bacterial liquid supply tank 25 via a main liquid supply pipe 23. A peristaltic pump 24 is installed on the main liquid supply pipe 23.
[0052] The fixed clamp installation method makes it easy to disassemble, install, and fine-tune the position of the bacterial liquid injector, facilitating later maintenance and replacement. The design of the connecting branch pipes ensures synchronous and equal liquid supply to all injectors, guaranteeing the uniformity of bacterial liquid spraying from the pipeline level. The peristaltic pump can precisely adjust the liquid supply rate and volume, flexibly adjusting according to the organic fertilizer delivery rate and material thickness to ensure accurate bacterial liquid addition ratio. The bacterial liquid supply tank provides a continuous material source for bacterial liquid spraying, avoiding supply interruptions and improving operational continuity. The overall pipeline is designed in series, with a simple layout, reducing pipeline bends and lowering the risk of leakage and blockage.
[0053] Example 3, the microbial inoculant addition mechanism for bio-organic fertilizer production, is characterized by the following steps: Step 1, device installation and fixing; Step 2, precise adjustment of material passage gap; Step 3, inspection of microbial liquid delivery pipeline; Step 4, equipment linkage start-up; Step 5, microbial liquid spraying and addition.
[0054] Further, in step 1, the device is installed and fixed. The specific steps are as follows: the bottom plate A at the bottom of the left mounting plate and the bottom plate B at the bottom of the right mounting plate are respectively and securely installed on the frame on both sides of the feed end of the organic fertilizer conveying device, so that the mounting plate fixing beam is directly above the conveying trajectory of the organic fertilizer conveying device, and the bacterial liquid sprayer faces the upper belt of the organic fertilizer conveying device, initially ensuring that there is a material passage gap between the bottom side of the bacterial liquid sprayer and the upper belt.

After the adjustment is completed, the levelness and stability of the mounting plate fixing beam are checked to ensure that the material passage gap of all bacterial liquid injectors is uniform.
[0056] Step 3, the inspection of the bacterial liquid delivery pipeline, specifically involves the following steps: checking the amount of organic fertilizer bacterial liquid in the bacterial liquid supply tank to ensure that the storage capacity meets the addition requirements; sequentially checking the connection and sealing of the main supply pipe, connecting branch pipe and bacterial liquid injector to confirm that there is no leakage or blockage; and checking the operating status of the peristaltic pump to ensure that it can start and stop normally and adjust the supply rate.
[0057] Step 4 involves the coordinated start-up of the equipment. The specific steps are as follows: 1. Start the organic fertilizer conveying device to operate at a preset conveying rate to ensure that the organic fertilizer material can pass through the material passage gap below the bacterial liquid sprayer at a uniform speed; 2. Start the peristaltic pump to transport the bacterial liquid in the supply tank to the connecting branch pipe through the main supply pipe, and then distribute it to each group of equally spaced bacterial liquid sprayers through the connecting branch pipe. The peristaltic pump can adjust the supply volume of bacterial liquid according to the conveying rate of the organic fertilizer and the thickness of the material to ensure accurate bacterial liquid addition ratio.
[0058] Step 5: Adding bacterial solution by spraying. The specific steps are as follows: the bacterial solution is sprayed downwards synchronously by each group of bacterial solution sprayers and evenly applied to the surface of the organic fertilizer material on the upper belt of the organic fertilizer conveying device. Because the bacterial solution sprayers are installed at equal intervals on the fixed crossbeam of the mounting plate and the organic fertilizer is conveyed at a uniform speed, the bacterial solution is evenly added to the organic fertilizer material. The material continues to operate with the conveying device to complete the initial mixing of bacterial solution and organic fertilizer.
[0059] The equipment linkage speed matching requirements enable precise coordination between organic fertilizer delivery and bacterial solution supply, ensuring the accuracy of bacterial solution addition ratio and avoiding waste or insufficient addition; relying on structural advantages, the bacterial solution is evenly sprayed and initially mixed during delivery, improving the fusion effect between bacterial solution and organic fertilizer, laying the foundation for subsequent treatment.
[0060] Based on the organic fertilizer delivery rate, delivery rate per unit area, and preset addition ratio, the theoretical total spray volume Q of the bacterial solution is calculated, and precise matching is achieved through adjustment of the supply system. The calculation formula and operation are as follows:
[0061] Calculation formula: Q (kg / min) = Conveying speed V (m / min) × Conveying device width L (m) × Conveying capacity per unit area M (kg / ㎡) × Addition ratio K, K is usually 0.5%~5%.
[0062] Operating steps:
[0063] Based on the calculated value Q, adjust the flow regulating valve of the liquid supply system and set the total amount of bacterial liquid sprayed.
[0064] Turn on the organic fertilizer delivery device and the bacterial liquid supply system, conduct a joint test spray, collect the bacterial liquid sprayed from all the sprayers within 1 minute, weigh it and compare it with the theoretical value Q, and control the error within ±3%.
[0065] If the error exceeds the range, fine-tune the flow regulating valve until the actual injection volume matches the theoretical value, thus completing the parameter calibration.
[0066] The microbial inoculant addition mechanism for bio-organic fertilizer production described in this invention uses a left-side mounting plate and a right-side mounting plate as mounting bases, fixed on both sides of the organic fertilizer conveying device. A crossbeam fixed to the mounting plates serves as the carrier for the injectors. Multiple sets of microbial liquid injectors are installed at equal intervals along the length of the crossbeam, achieving full coverage and uniform spraying of the conveying area. The modular assembly and reasonable installation layout do not affect the original operation of the conveying device. Relying on the coordinated operation of the dual-sided height adjustment mechanism, the height of the material passage gap can be flexibly adjusted to ensure that the microbial liquid injectors are always above the conveying path of the organic fertilizer conveying device, achieving uniform spraying of the microbial liquid and completing the initial mixing with the organic fertilizer.
[0067] The microbial inoculant addition mechanism for bio-organic fertilizer production described in this invention features a simple threaded adjustment mechanism that allows for precise lifting and lowering of the left hollow connecting rod, thereby accurately adjusting the height of the corresponding side injector. The sliding cooperation between the slide rail and the slider limits the swaying of the connecting rod, ensuring the stability of the mounting plate fixing the crossbeam during lifting.

9. A method for adding microbial inoculants in the production of bio-organic fertilizer, characterized in that, The process includes the following steps: Step 1, installing and fixing the device; Step 2, precisely adjusting the material flow gap; Step 3, inspecting the bacterial solution delivery pipeline; Step 4, starting the equipment in conjunction with the system; and Step 5, adding the bacterial solution by spraying.
10. The method for adding microbial inoculants for the production of bio-organic fertilizer according to claim 1, characterized in that, Step 1, the device is installed and fixed. The specific steps are as follows: the bottom plate A at the bottom of the left mounting plate and the bottom plate B at the bottom of the right mounting plate are respectively and firmly installed on the frame on both sides of the feed end of the organic fertilizer conveying device, so that the mounting plate fixing beam is directly above the conveying track of the organic fertilizer conveying device, and the bacterial liquid sprayer faces the upper belt of the organic fertilizer conveying device, initially ensuring that there is a material passage gap between the bottom side of the bacterial liquid sprayer and the upper belt. In step 2, the material passage gap is precisely adjusted by coordinating the first height adjustment mechanism and the second height adjustment mechanism to finely adjust the material passage gap between the bacterial liquid injector and the upper belt of the organic fertilizer conveying device to adapt to organic fertilizer materials of different particle sizes and thicknesses. After the adjustment is completed, the levelness and stability of the mounting plate fixing beam are checked to ensure that the material passage gap of all bacterial liquid injectors is uniform. Step 3, the inspection of the bacterial liquid delivery pipeline, specifically involves the following steps: checking the amount of organic fertilizer bacterial liquid in the bacterial liquid supply tank to ensure that the storage capacity meets the addition requirements; sequentially checking the connection and sealing of the main supply pipe, connecting branch pipe and bacterial liquid injector to confirm that there is no leakage or blockage; and checking the operating status of the peristaltic pump to ensure that it can start and stop normally and adjust the supply rate. Step 4 involves the coordinated start-up of the equipment. The specific steps are as follows:
1. Start the organic fertilizer conveying device to operate at a preset conveying rate to ensure that the organic fertilizer material can pass through the material passage gap below the bacterial liquid sprayer at a uniform speed; 2. Start the peristaltic pump to transport the bacterial liquid in the supply tank to the connecting branch pipe through the main supply pipe, and then distribute it to each group of equally spaced bacterial liquid sprayers through the connecting branch pipe. The peristaltic pump can adjust the supply volume of bacterial liquid according to the conveying rate of the organic fertilizer and the thickness of the material to ensure accurate bacterial liquid addition ratio. Step 5: Adding bacterial solution by spraying. The specific steps are as follows: the bacterial solution is sprayed downwards synchronously by each group of bacterial solution sprayers and evenly applied to the surface of the organic fertilizer material on the upper belt of the organic fertilizer conveying device. Because the bacterial solution sprayers are installed at equal intervals on the fixed crossbeam of the mounting plate and the organic fertilizer is conveyed at a uniform speed, the bacterial solution is evenly added to the organic fertilizer material. The material continues to operate with the conveying device to complete the initial mixing of bacterial solution and organic fertilizer.
