Description

Technical Field

[0001] This utility model relates to the field of organic fertilizer fermentation technology, specifically an organic fertilizer fermentation device with adjustable humidity. Background Technology

[0002] Organic fertilizer is made from livestock and poultry manure and various industrial and agricultural by-products as the main raw materials. After being treated with high-temperature fermentation, composting, deodorization and other harmless processes, it is produced in accordance with national standards. Its total nitrogen, phosphorus and potassium content is greater than 5%, and its organic matter content is greater than 45%. It is not only suitable for field crops such as rice, wheat, corn and rapeseed, but also for horticultural plants such as vegetables, melons and fruits, forest fruits, flowers and other cash crops.

[0003] During the fermentation of organic fertilizer, the moisture content of the raw materials affects the fermentation process. Existing fermentation devices typically separate the stirring and humidifying functions, resulting in poor synergy between the two and low fermentation uniformity. Therefore, those skilled in the art have provided an organic fertilizer fermentation device with adjustable humidity to address the problems mentioned in the background section. Utility Model Content

[0004] The purpose of this invention is to provide an organic fertilizer fermentation device with adjustable humidity to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An adjustable humidity organic fertilizer fermentation device includes a fermentation tank, a controller, a feed hopper, a rotating disc, and an exhaust pipe. The controller is fixedly installed on one side of the fermentation tank. A top plate is fixedly connected to the upper end of the fermentation tank, and a rotating disc is rotatably connected to the center of the top plate. A water tank is fixedly connected to the upper end of the rotating disc, and a driven gear is fixedly connected to the outer wall of the rotating disc. A support frame is provided in front of the water tank, and the support frame is fixedly connected to the top plate. A servo motor is fixedly installed on the upper end of the support frame, and the servo motor is electrically connected to the control box. A rotating shaft is fixedly connected to the power output end of the servo motor, and the rotating shaft is rotatably connected to the support frame and the top plate. A drive gear is fixedly connected to the rotating shaft, and the drive gear meshes with the driven gear. A fixed rod is fixedly connected to the lower end of the rotating disc, and a nozzle is fixedly connected to the fixed rod. A stirring rod is provided below the nozzle, and the stirring rod is fixedly connected to the fixed rod. Ball bearings are movably connected to both ends of the nozzle.

[0006] As a further embodiment of this utility model: a connecting pipe is fixedly connected to the upper end of the nozzle, wherein the connecting pipe is connected to the nozzle, the upper end of the connecting pipe is fixedly connected to the water tank, and the connecting pipe is connected to the inside of the water tank. A second electrically controlled valve is fixedly installed on the connecting pipe, and a discharge port is opened at the lower end of the fermentation tank, and a first electrically controlled valve is fixedly installed on the discharge port.

[0007] As a further embodiment of this utility model: a base is fixedly connected to the outer wall of the fermentation tank, a foot pad is fixedly connected to the lower end of the base, a protruding ring is fixedly connected to the bottom outer wall of the rotating disk, wherein the protruding ring is locked inside the top plate, a water inlet is opened at the upper end of the water tank, a sealing cap is threadedly connected to the water inlet, an exhaust pipe is fixedly connected to the upper end of the rotating disk, wherein the exhaust pipe is connected to the inside of the fermentation tank, a filter screen is fixedly installed at the lower end of the exhaust pipe, an exhaust fan is set above the filter screen, wherein the exhaust fan is installed on the exhaust pipe, and an exhaust solenoid valve is set above the exhaust fan.

[0008] As a further embodiment of this utility model: a feeding hopper is fixedly connected to one side of the fermentation tank, and a feeding port is provided between the feeding hopper and the fermentation tank, through which materials can be poured into the fermentation tank. Sliding grooves are provided on the inner walls of both the left and right sides of the feeding hopper, and an insertion plate is inserted into the feeding hopper, wherein the insertion plate is slidably connected in the sliding groove.

[0009] As a further embodiment of this utility model: one end of the insertion plate is fixedly connected to a limiting block, wherein the insertion plate can be inserted into or pulled out of the feed hopper by means of the limiting block; an annular groove is provided on the inner wall of the fermentation tank, wherein a ball bearing is movably connected in the annular groove, and the annular groove of the ball bearing can support and limit the nozzle; a water content sensor is fixedly installed inside the fermentation tank, wherein the water content sensor is electrically connected to the controller.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. Precise humidity control, adaptable to diverse raw materials: The water content sensor monitors the humidity inside the fermentation tank in real time. Together with the controller and electronically controlled valves, it automatically replenishes or stops water, precisely controlling the fermentation humidity. It can adapt to both low-moisture raw materials such as straw and high-moisture materials such as livestock and poultry manure, ensuring a stable fermentation environment and improving the consistency of organic fertilizer quality.

[0011] 2. Synergistic mixing and humidification for more uniform fermentation: The servo motor drives the gear transmission, allowing the mixing rod and spray nozzle to rotate synchronously. The mixing rod turns the material and breaks up the pile; the rotating spray nozzle expands the water spraying range, mixing and humidifying at the same time, so that the moisture of the material is evenly distributed, avoiding uneven local dryness and wetness that affects the fermentation effect and promoting the full decomposition of organic matter.

[0012] 3. Support and Limitation, Reduced Friction: The ball bearings, in conjunction with the annular groove, provide a stable support point for the nozzle. During operation, the nozzle rotates with the fixed rod to perform water spraying and agitation. The ball bearings can bear part of the weight of the nozzle and related components, sharing the force on the fixed rod and preventing the nozzle from sagging or wobbling excessively due to its own weight and the forces exerted during operation. This ensures that the nozzle maintains a relatively stable spatial position during rotation, making the agitation and spraying actions smoother. Simultaneously, the annular groove limits the movement trajectory of the ball bearings, thus constraining the rotation trajectory of the nozzle, ensuring that the nozzle can only rotate along the circumference of the annular groove, preventing the nozzle from... Horizontal (non-rotational) offset and oscillation ensure that the nozzle makes regular circular motion around the central axis of the fermentation tank, allowing the stirring rod to evenly turn the material and the nozzle to evenly spray water, improving the uniformity of fermentation. In addition, the ball bearings and the annular groove have rolling contact, which has less rolling friction resistance compared to sliding contact (such as the nozzle directly contacting the inner wall of the fermentation tank without ball bearings). When the nozzle rotates, it can move more smoothly along the annular groove, reducing power loss. This allows the servo motor and other drive components to drive the nozzle to rotate more easily, reducing equipment operating energy consumption. At the same time, it can also reduce component wear and extend the service life of the nozzle, fixing rod, and related structures on the inner wall of the fermentation tank.

A first electrically controlled valve 5 is fixedly installed on the inlet 4. A base 2 is fixedly connected to the outer wall of the fermentation tank 1, and a foot pad 3 is fixedly connected to the lower end of the base 2. A protruding ring 23 is fixedly connected to the bottom outer wall of the rotating disk 11, and the protruding ring 23 is locked in the top plate 6. A water inlet 9 is opened at the upper end of the water tank 8, and a sealing cap 10 is threaded onto the water inlet 9. An exhaust pipe 16 is fixedly connected to the upper end of the rotating disk 11, and the exhaust pipe 16 is connected to the inside of the fermentation tank 1. A filter screen 24 is fixedly installed at the lower end of the exhaust pipe 16, and an exhaust fan 25 is set above the filter screen 24. The exhaust fan 25 is installed on the exhaust pipe 16, and an exhaust solenoid valve 26 is set above the exhaust fan 25. A feed hopper 29 is fixedly connected to one side of the fermentation tank 1. The feed hopper 29 is connected to the fermentation tank 1. A feed inlet 30 is provided between the fermentation tanks 1, through which materials can be poured into the fermentation tanks 1. Sliding grooves 31 are provided on the inner walls of the left and right sides of the feed hopper 29. An insertion plate 32 is inserted into the feed hopper 29, and the insertion plate 32 is slidably connected in the sliding groove 31. One end of the insertion plate 32 is fixedly connected to a limiting block 33, through which the insertion plate 32 can be inserted or pulled out from the feed hopper 29.

A water content sensor 27 is fixedly installed inside the fermentation tank 1, and the water content sensor 27 is electrically connected to the controller.

[0024] The working principle of this utility model is as follows: First, the insertion plate 32 is pulled out by the limiting block 33, exposing the feed inlet 30. Organic fertilizer raw materials (such as straw, livestock manure, etc.) are poured into the feed hopper 29 and enter the fermentation tank 1 through the feed inlet 30. Then, the insertion plate 32 is pushed along the slide groove 31 to close the feed inlet 30, preventing material splashing and odor overflow during fermentation. Next, the servo motor 13 is turned on, driving the rotating shaft 14 to rotate. The rotating shaft 14 drives the drive gear 15 to rotate, which in turn drives the driven gear 12 to rotate. The driven gear 12 drives the rotating disk 11 to rotate, which in turn drives the fixed rod 18 to rotate. The fixed rod 18 then drives the nozzle 19 and the stirring rod 17 to rotate. The stirring rod 17 begins to agitate the material. Simultaneously, the moisture content sensor 27 monitors the material's humidity in real time and sends feedback to the controller. When the humidity is insufficient, the controller opens the second electrically controlled valve 22, and water from the water tank 8 is sprayed onto the material through the connecting pipe 21 and the nozzle 19. The rotating nozzle 19 expands the spraying range, working in conjunction with the stirring to achieve uniform humidification. Once the humidity reaches the target, the second electrically controlled valve 22 is closed to maintain stable fermentation humidity. Then, during aerobic fermentation, the exhaust fan 25 and the exhaust solenoid valve 26 are turned on to exhaust waste gas and introduce air. When an anaerobic environment is required, the exhaust fan 25 and the exhaust solenoid valve 26 are turned off to create a sealed space. Finally, after fermentation is complete, the first electrically controlled valve 5 is opened, and the fermented organic fertilizer is discharged from the outlet 4, completing the entire fermentation process. In this way, the device relies on mechanical transmission, intelligent sensing, and control to achieve "uniform stirring, precise humidity control, and automated process" in organic fertilizer fermentation, adapting to different raw materials and fermentation process requirements, and helping to efficiently produce high-quality organic fertilizer.
