Description

Technical Field

[0001] This invention relates to the field of microbial fertilizer production technology, specifically a vegetable leaf fermentation fertilizer production device with added microbial agents. Background Technology

[0002] The nutritional characteristics and fertilization requirements of various vegetables vary depending on their main biological characteristics and the different edible parts. Therefore, the types of fertilizers required also differ. Attention should be paid to appropriately increasing the application of phosphorus and potassium fertilizers and controlling the amount of nitrogen fertilizer. Sufficient potassium fertilizer can make the photosynthesis of vegetables vigorous. If the supply of nitrogen, phosphorus and potassium nutrients is insufficient, the vegetative growth of the plant will be inhibited, the size and number of leaves will not meet the requirements for high yield, and the development of flowers will also be inhibited, making it difficult to achieve high yield. However, the fermentation waste of vegetable leaves can fully meet the demand for large amounts of fertilizers, and the process of preparing these fertilizers is also relatively complex.

[0003] In the process of preparing the waste, the vegetable leaves to be fermented are first washed, impurities removed, and mashed into a pulp before being mixed with other ingredients for fermentation. Attention must be paid to the moisture content, which should be adjusted to 60%-65%. Too little water will slow fermentation, while too much water will result in poor permeability. The fermentation temperature should be controlled above 15-20℃. The material should be completely sealed, but the internal pressure should not be too high. Attention must also be paid to the proportion of raw materials and the amount of microbial inoculant added; these are all factors contributing to successful and efficient fertilizer production. Summary of the Invention

[0004] The purpose of this invention is to provide a vegetable leaf fermentation fertilizer production device with added microbial agents to solve the problems raised in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The fertilizer production device includes a fermentation tank with a rotatable lifting cover. The lifting cover has ventilation holes with ventilation valves inside. A pressure-sensing component is installed inside the fermentation tank, electrically connected to the ventilation valves via wires. A layered rack is installed inside the fermentation tank. A water inlet pipe is connected to the fermentation tank. A mixing rack is rotatably connected to the fermentation tank. A transmission mechanism is located at the bottom of the fermentation tank, with its output slidably connected to the mixing rack. A water filter rack with a permeable mesh is located at the bottom of the fermentation tank. A weight-sensing component is installed inside the fermentation tank. A return water pump is installed in the water inlet pipe, electrically connected to the return water pump via wires. A pesticide inlet is located on the lifting cover, with a pesticide dispenser installed thereon, connected to the weight-sensing component via wires. The electrical connection is used during fermentation. Vegetable leaves are fed into the fermentation tank, and the lifting lid is then closed. Microbial inoculants are added to the vegetable leaves, and water is added to the fermentation tank. While adding water, the transmission mechanism is activated, causing the mixing rack to rotate. The mixing rack crushes the vegetable leaves, allowing water to flow into them. This ensures the vegetable leaves are in full contact with the water, removing dirt and other contaminants. The water also flows out of the layering rack and is detected by the weight-sensing component. When the water flow rate increases, the weight-sensing component transmits an electrical signal, stopping the stirring and water supply. The water on the weight-sensing component is then discharged from the fermentation tank. The pressure-sensing component senses the pressure changes generated during fermentation and then controls the vent valve to regulate the internal pressure of the fermentation tank.

[0007] The fermentation tank is equipped with a feeding chute and multiple swirling discs on a tiered rack. Each swirling disc is slidably connected to the tiered rack. A swing box is installed on the fermentation tank and is connected to it. The swing box contains a swing motor, and a swing rod is installed on the output end of the swing motor. The swing rod is rotatably connected to the swing box. During fermentation, vegetable leaves are fed into the fermentation tank through the feeding chute. Then, the swing motor is started, which drives the swing rod to rotate, causing the swirling discs to slide. During the sliding process, the swirling discs will tumble and compress the vegetable leaves, increasing the density between the leaves and squeezing out excess water. This ensures that the vegetable leaves are in full contact with the microbial inoculum and allows the leaves to absorb some of the inoculum, increasing the fermentation speed.

[0008] The swing rod is equipped with multiple swing discs, which slide in contact with corresponding surging discs. Multiple surging springs are installed on the edge of the surging discs, with each surging spring abutting against its corresponding surging disc and fermentation tank at both ends. Multiple push-out racks are installed on the tiered rack, which slide in contact with their corresponding surging discs. When the vegetable leaves are turned over, the swing rod, driven by the swing motor, drives the swing discs to rotate. After the swing discs rotate, they will squeeze the surging discs, while the surging springs are responsible for resetting the surging discs. The surging discs will slide fully within the tiered rack, thereby squeezing the vegetable leaves. The push-out racks can not only block the vegetable leaves but also peel off the vegetable leaves that are stuck to the surging discs.

[0009] The transmission mechanism includes a drive motor, a drive rod with drive teeth on its output end, and a drive bevel gear at the bottom of the mixing rack. The bevel gear meshes with the drive teeth on the drive rod. A sealing assembly is fitted onto the mixing rack, and the side of the sealing assembly away from the mixing rack is connected to the fermentation tank. The drive motor drives the drive rod to rotate, and the teeth on the drive rod drive the drive bevel gear to rotate. The mixing rack can thus rotate, thoroughly breaking up and mixing the vegetable leaves. The sealing assembly prevents moisture and water leakage, while also ensuring the normal operation of the pressure sensing component and reducing sensing errors.

[0010] The weighing assembly includes a weighing tank that is slidably connected to the fermentation tank. A weighing cylinder is located at the bottom of the fermentation tank, and a lifting rod is located at the bottom of the weighing tank. The lifting rod is slidably connected to the weighing cylinder, and a weighing spring is installed inside the weighing cylinder. The two ends of the weighing spring abut against the lifting rod and the weighing cylinder, respectively. When water is discharged from the mixture of vegetable leaves, the water will enter the weighing tank. As the weight increases, the weighing tank moves inside the fermentation tank, which in turn moves the lifting rod inside the weighing cylinder. The weighing cylinder transmits an electrical signal, which serves two purposes: first, to control the water stop command when water is added for the first time; and second, to replenish water in a timely manner during the fermentation process to ensure the fermentation effect.

[0011] A measuring plate is installed inside the weighing cylinder, and a circuit wave plate is installed on the measuring plate. A sliding plate is installed on the lifting rod, and the sliding plate slides in contact with the circuit wave plate. The measuring plate is electrically connected to the return water pump through a wire. A water-blocking piston is installed on the weighing cylinder, which is sleeved on the lifting rod and slides in contact with the lifting rod. When the lifting rod moves inside the weighing cylinder, the lifting plate will drive the sliding plate to slide on the circuit wave plate on the measuring plate. The circuit wave plate will sense the position change and speed of the sliding plate and transmit a corresponding electrical signal. When water is added for the first time, when the water flow rate in the weighing tank is fast, water addition is stopped and fermentation is allowed. During fermentation, when the water volume in the weighing tank is large, water needs to be added in time.

[0012] The pressure-sensing assembly includes a pressure-sensing hood positioned above the layered rack. Inside the hood is a pressure-measuring airbag, with a feedback tube on the airbag. Inside the feedback tube is a feedback piston, with a moving rod on the piston. A critical switch is located within the feedback tube, and the moving rod slides in contact with the critical switch. The critical switch is electrically connected to the dosing device via a wire. During fermentation, the pressure-sensing hood senses the pressure inside the fermenter and pulls the pressure-measuring airbag. When the pressure is too high, the airbag is compressed, and gas enters the feedback tube, causing the feedback piston to move. The feedback piston drives the moving rod to rotate, bringing it into contact with the critical switch, thus controlling the feeding of the microbial inoculum. If the internal pressure remains unchanged for an extended period, microbial inoculum must also be added to prevent insufficient inoculum and slow fermentation. Simultaneously, when the internal pressure increases, the vent valve must be controlled to release excess gas and maintain the oxygen content inside the fermenter.

[0013] The dosing device includes a dosing pipe with a pressurizing cylinder inside. A push wedge is located at the output end of the pressurizing cylinder, and a push piston is mounted on the push wedge. An injection branch pipe is connected to the dosing pipe. When the uppermost part of the push wedge is above the injection branch pipe, the pressurizing cylinder will drive the push wedge to move during pressurization, which in turn moves the push piston. This reduces the problem of drug adhesion and spoilage of the microbial inoculum. Furthermore, the pressurizing cylinder is controlled by a pressure-sensing component, allowing for more intelligent addition of the microbial inoculum.

[0014] The fermenter is equipped with a backwashing assembly, which includes a backwash pipe and a backwash pump. The backwash pipe is connected to the fermenter and the output end of the backwash pump. A pressurized nozzle is installed at the end of the backwash pipe away from the backwash pump. A backwash ring is installed inside the fermenter. The pressurized nozzle is rotatably connected to the backwash ring and the backwash pipe. Before fermentation, the filter rack and permeable mesh need to be rinsed to reduce contamination. After fermentation, rinsing is also required. The backwash pump sends water into the backwash pipe and then into the pressurized nozzle. The pressurized nozzle rotates under the action of the backwash ring and the fan blades inside the pressurized nozzle, thereby thoroughly cleaning the permeable mesh, the surging plate, and the stratification rack.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This invention employs an automatic water-adding function. By detecting the water permeability of the vegetable leaf fertilizer, the current water flow effect of the fertilizer can be fully understood, and timely water replenishment can be carried out. This can ensure the activity of the fertilizer during fertilizer preparation and increase the fermentation speed.

[0017] 2. This invention employs a pressure-sensing component to sense the air pressure inside the fermentation tank and regulate the air pressure inside the fermentation tank based on the sensed structure. This ensures the activity of the fertilizer inside the fermentation tank, prevents the fertilizer solution from easily being lost, and automatically adjusts the dosage, reducing the problem of waste contamination caused by manual intervention.

[0018] 3. It adopts an automatic surging and crushing structure, which can ensure that the vegetable leaves inside can be fully mixed and crushed. At the same time, the squeezing effect ensures that the vegetable leaves can fully absorb the microbial inoculum, thereby improving the fermentation speed and fermentation completion rate.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example: Figures 1-8 As shown, the present invention provides a technical solution.

[0030] The fertilizer production device includes a fermentation tank 1, a lifting cover 2 rotatably connected to the fermentation tank 1, a vent hole on the lifting cover 2, and a vent valve 3 installed in the vent hole. A pressure sensing component 4 is installed inside the fermentation tank 1, electrically connected to the vent valve 3 via a wire. A layered rack 5 is installed inside the fermentation tank 1. A water inlet pipe 6 is installed on the fermentation tank 1, communicating with it. A mixing rack 7 is installed inside the fermentation tank 1, rotatably connected to it. A transmission mechanism 8 is installed at the bottom of the fermentation tank 1, with its output end slidably connected to the mixing rack 7. A water filter rack 9 is installed at the bottom inside the fermentation tank 1, with a permeable mesh 10 installed on it. A weight sensing component 11 is installed inside the fermentation tank 1. A return water pump 12 is installed in the water inlet pipe 6, electrically connected to the return water pump 12 via a wire. A dosing port is installed on the lifting cover 2, with a dosing device 13 installed on the dosing port. The device 13 is electrically connected to the weight-sensing component 11 via a wire. During fermentation, vegetable leaves are fed into the fermentation tank 1, and then the lifting cover 2 is closed. Microbial inoculants are added to the vegetable leaves, and water is added to the fermentation tank 1. While adding water, the transmission mechanism 8 is activated to rotate the mixing rack 7. The mixing rack 7 crushes the vegetable leaves while allowing water to flow into them. The vegetable leaves are in full contact with the water, which not only removes the dirt adhering to the leaves, but also allows the water to flow out of the layering rack 5 and be sensed by the weight-sensing component 11. When the water flow rate increases, the weight-sensing component 11 will transmit an electrical signal, at which point stirring and water supply will stop, and the water on the weight-sensing component 11 will be discharged from the fermentation tank 1. The pressure-sensing component 4 senses the changes in air pressure generated during fermentation and then controls the vent valve 3 to regulate the air pressure inside the fermentation tank 1.

[0031] The fermentation tank 1 is equipped with a feeding chute 101, and a series of surging discs 501 are installed on the layered rack 5. Each surging disc 501 is slidably connected to the layered rack 5. The fermentation tank 1 is equipped with a swing box 502, which is connected to the fermentation tank 1. The swing box 502 is equipped with a swing motor 503, and a swing rod 504 is installed on the output end of the swing motor 503. The swing rod 504 is rotatably connected to the swing box 502. During fermentation, vegetable leaves are fed into the fermentation tank 1 through the feeding chute 101. Then, the swing motor 503 is started, which drives the swing rod 504 to rotate, causing the surging discs 501 to slide. During the sliding process, the surging discs 501 will tumble and squeeze the vegetable leaves, increasing the density between the vegetable leaves and squeezing out excess water, so that the vegetable leaves can fully contact the microbial inoculum and absorb some of the microbial inoculum, thereby increasing the fermentation speed.

[0032] Multiple swing disks 505 are provided on the swing rod 504. The swing disks 505 slide in contact with the corresponding surging disks 501. Multiple surging springs 506 are provided on the edge of the surging disks 501. Each surging spring 506 abuts against the corresponding surging disk 501 and fermentation tank 1 at both ends. Multiple push-out racks 507 are provided on the layer rack 5. The push-out racks 507 slide in contact with the corresponding surging disks 501. When the vegetable leaves are turned over, the swing rod 504 drives the swing disks 505 to rotate under the drive of the swing motor 503. After the swing disks 505 rotate, they will squeeze the surging disks 501. The surging springs 506 are responsible for the reset of the surging disks 501. The surging disks 501 will slide fully in the layer rack 5, thereby squeezing the vegetable leaves. The push-out racks 507 can not only block the vegetable leaves, but also peel off the vegetable leaves that are stuck to the surging disks 501.

[0033] The transmission mechanism 8 includes a transmission motor 801, a transmission rod 802 on the output end of the transmission motor 801, and transmission teeth on the transmission rod 802. A transmission bevel gear 701 is provided at the bottom of the mixing frame 7. The transmission bevel gear 701 meshes with the transmission teeth on the transmission rod 802. A sealing component 14 is fitted on the mixing frame 7. The side of the sealing component 14 away from the mixing frame 7 is connected to the fermentation tank 1. The transmission motor 801 will drive the transmission rod 802 to rotate, and the teeth on the transmission rod 802 will drive the transmission bevel gear 701 to rotate. The mixing frame 7 can thus rotate and fully disperse and mix the vegetable leaves. The sealing component 14 prevents water vapor and water leakage, and also ensures the normal operation of the pressure sensing component 4 and reduces sensing errors.

[0034] The weight-sensing component 11 includes a weight-sensing groove 1101, which is slidably connected to the fermentation tank 1. A weighing cylinder 1102 is provided at the bottom of the fermentation tank 1, and a lifting rod 1103 is provided at the bottom of the weight-sensing groove 1101. The lifting rod 1103 is slidably connected to the weighing cylinder 1102, and a weighing spring 1104 is provided inside the weighing cylinder 1102. The two ends of the weighing spring 1104 abut against the lifting rod 1103 and the weighing cylinder 1102, respectively. When water is discharged from the mixture of vegetable leaves, the water will enter the weight-sensing groove 1101. As the weight increases, the weight-sensing groove 1101 moves inside the fermentation tank 1, and drives the lifting rod 1103 to move inside the weighing cylinder 1102. The weighing cylinder 1102 transmits an electrical signal, which firstly controls the water stop command when water is added for the first time, and secondly replenishes water in a timely manner during the fermentation process to ensure the fermentation effect.

[0035] A measuring plate 1105 is installed inside the weighing cylinder 1102. A circuit oscillating plate 1106 is installed on the measuring plate 1105. A sliding plate 1107 is installed on the lifting rod 1103, and the sliding plate 1107 slides in contact with the circuit oscillating plate 1106. The measuring plate 1105 is electrically connected to the return water pump 12 via a wire. A water-blocking piston 1108 is installed on the weighing cylinder 1102, and the water-blocking piston 1108 is sleeved on the lifting rod 1103 and slides in contact with the lifting rod 1103. The lifting rod 1103 is in weighing... When moving inside cylinder 1102, the lifting plate will drive the sliding plate 1107 to slide on the circuit wave plate 1106 on the measuring plate 1105. The circuit wave plate 1106 will sense the position change and speed of the sliding plate 1107 and transmit the corresponding electrical signal. When water is added for the first time, when the water flow rate in the weight tank 1101 is fast, water addition is stopped and fermentation is waited for. During the fermentation process, when the water volume in the weight tank 1101 is large, water needs to be added in time.

[0036] The pressure-sensing component 4 includes a pressure-sensing cover 401, which is positioned above the layered rack 5. A pressure-measuring airbag 402 is installed inside the pressure-sensing cover 401. A feedback tube 403 is installed on the pressure-measuring airbag 402, and a feedback piston 404 is installed inside the feedback tube 403. A moving rod 405 is installed on the feedback piston 404, and a critical switch 406 is installed inside the feedback tube 403. The moving rod 405 slides in contact with the critical switch 406. The critical switch 406 is electrically connected to the dosing device 13 via a wire. During fermentation, the pressure-sensing cover 401 will sense the air pressure inside the fermenter 1 and pull the pressure-measuring airbag 402. When the pressure is too high, the pressure measuring bladder 402 is compressed, and the gas will enter the feedback tube 403, causing the feedback piston 404 in the feedback tube 403 to move. The feedback piston 404 drives the moving rod 405 to rotate, thereby contacting the critical switch 406, thus controlling the feeding of the microbial inoculum. When the internal pressure does not change for a long time, microbial inoculum also needs to be fed in to avoid insufficient microbial inoculum, which would lead to slow fermentation. At the same time, when the internal gas pressure increases, the vent valve 3 needs to be controlled to release the pressure to avoid internal gas pressure, while also ensuring the oxygen content inside the fermenter 1.

[0037] The dosing device 13 includes a dosing pipe 1301, a pressurizing cylinder 1302 inside the dosing pipe 1301, a pushing wedge 1303 on the output end of the pressurizing cylinder 1302, a pushing piston 1304 on the pushing wedge 1303, and an injection branch pipe 1305 on the dosing pipe 1301, which is connected to the dosing pipe 1301. When the uppermost part of the pushing wedge 1303 is above the injection branch pipe 1305, during pressurization, the pressurizing cylinder 1302 will drive the pushing wedge 1303 to move, and at the same time, it will also cause the pushing piston 1304 to move, thereby reducing the problem of microbial inoculum deterioration caused by drug adhesion. At the same time, the pressurizing cylinder 1302 is controlled by the pressure sensing component 4, which allows for more intelligent addition of microbial inoculum.

[0038] Fermentation tank 1 is equipped with a backwashing assembly 15, which includes a backwash pipe 1501 and a backwash pump 1502. The backwash pipe 1501 is connected to fermentation tank 1 and to the output end of backwash pump 1502. A pressure nozzle 1503 is provided at the end of backwash pipe 1501 away from backwash pump 1502. A backwashing ring is provided inside fermentation tank 1. The pressure nozzle 1503 is rotatably connected to the backwashing ring and rotates with the backwash pipe 1501. Before fermentation, the filter rack 9 and the permeable net 10 need to be rinsed to reduce contamination. After fermentation, they also need to be rinsed. The backwash pump 1502 will send water into the backwash pipe 1501 and then into the pressurized nozzle 1503. The pressurized nozzle 1503 rotates under the action of the backwash ring and the fan blades inside the pressurized nozzle 1503, thereby thoroughly cleaning the permeable net 10, the surging plate 501, and the layered rack 5.

[0039] Working Principle: Before fermentation, the filter rack 9 and permeable net 10 need to be rinsed. The backwash pump 1502 will send water into the backwash pipe 1501 and then into the pressurized nozzle 1503 to thoroughly clean the permeable net 10, the surging plate 501, and the stratification rack 5. During fermentation, vegetable leaves are sent into the fermentation tank 1, and then the lifting cover 2 is closed. Microbial inoculant is then added to the vegetable leaves, and water is added to the fermentation tank 1. At the same time as adding water, the transmission mechanism 8 is started. The transmission motor 801 will drive the transmission rod 802 to rotate, and the teeth on the transmission rod 802 will drive the transmission bevel gear 701 to rotate, which will drive the mixing rack 7 to rotate. While the mixing rack 7 crushes the vegetable leaves, water can also flow into the vegetable leaves. The vegetable leaves are in full contact with water, which not only removes the dirt and other substances adhering to the leaves, but the water will also flow out of the stratification rack. 5. The water flow rate on the sensing tank 1101 is relatively fast, and the water addition is stopped. The water on the sensing component 11 will also be discharged from the fermentation tank 1. When the vegetable leaves are turned over, the swing rod 504 drives the swing disk 505 to rotate under the drive of the swing motor 503. After the swing disk 505 rotates, it will squeeze the surging disk 501. The pressure-sensing cover 401 will sense the air pressure in the fermentation tank 1 and pull the pressure measuring air bag 402. When the pressure is too high, the pressure measuring air bag 402 is compressed and the gas will enter the feedback pipe 403, causing the feedback piston 404 in the feedback pipe 403 to move. The feedback piston 404 drives the moving rod 405 to rotate, thereby contacting the critical switch 406. Then, the vent valve 3 is controlled to regulate the air pressure inside the fermentation tank 1, and the pressurizing cylinder 1302 is also controlled to work to ensure the fermentation speed.
