Description

Technical Field

[0001] The invention relates to the technical field of fertilization equipment, in particular to an automatic fertilization device using a bacterial agent in combination with a fertilizer. Background Art

[0002] In today's agricultural field, with the rapid development of science and technology and the continuous advancement of agricultural modernization, precision fertilization has become a key measure to increase crop yields, improve the quality of agricultural products, and protect the soil ecological environment. As a microbial product that can improve soil structure, enhance soil fertility, promote plant growth, and help resist pests and diseases, microbial agents, when used in combination with traditional fertilizers, have shown unique advantages and are gradually being widely used in various agricultural planting scenarios.

[0003] However, existing fertilization technology and equipment have exposed many limitations when facing the demand for the combination of microbial agents and fertilizers. The traditional manual fertilization method relies on farmers to manually spread fertilizers based on experience. It is not only labor-intensive and inefficient, but also difficult to accurately control the mixing ratio of microbial agents and fertilizers, which can easily lead to material waste and uneven fertilization, resulting in excess or insufficient nutrients for some crops, affecting overall growth and development.

[0004] Although some mechanized fertilization equipment has reduced the labor burden to a certain extent, most of them are designed for a single fertilizer and do not fully consider the special properties of microbial agents. The microbial flora in microbial agents are sensitive to the living environment, such as temperature, humidity, pH, and contact with fertilizers. Once these conditions are not properly controlled, the activity of the microorganisms will be inhibited or even die, thereby reducing the efficacy of the microbial agent. However, existing fertilization devices usually lack effective control mechanisms for these factors and cannot create suitable application conditions for microbial agents.

[0005] Furthermore, from the perspective of material storage and transportation, conventional storage boxes and transportation pipelines often cannot meet the requirements of the coordinated operation of microbial agents and fertilizers. Microbial agents are easily affected by moisture, agglomeration, and contamination, and require a sealed, dry, and heat-insulated storage environment. Existing storage facilities are difficult to provide such delicate conditions. During the transportation process, due to the difference in the physical properties of microbial agents and fertilizers, the two are prone to adhesion and clogging of pipelines after mixing, resulting in interruptions in fertilization operations and affecting agricultural production progress.

[0006] In addition, the existing fertilization equipment also has a lot of room for improvement in terms of fertilization uniformity. Whether it is a sprinkler or a broadcast fertilization device, it is difficult to ensure that the mixture of microbial agents and fertilizers can be evenly distributed on a large area of ​​farmland, which often leads to uneven distribution of nutrients in the field and excessive or low fertility in some areas, which is not conducive to the balanced growth of crops and may also cause environmental problems such as soil compaction and water pollution. Summary of the invention

The outer walls of the second bearing are respectively fixedly connected to the inner wall of the upper plate one, and the inner wall of the one-way bearing one and the inner wall of the one-way bearing two are respectively provided with a groove one and a groove two corresponding to the convex strip one. When the upper plate one and the lower plate one are engaged with each other, the convex strip one is inserted into the groove one, and the stirring shaft rotates freely in the forward direction. When the stirring shaft rotates in the reverse direction, the one-way bearing one is locked, driving the upper plate one to reverse. The upper plate one is lifted under the action of the spiral inclined surface, the convex strip one is separated from the groove one, and is inserted into the groove two. At this time, the stirring shaft rotates freely in the reverse direction. When rotating forward, the one-way bearing two is locked, driving the upper plate one to rotate forward. Under the action of gravity, the upper plate one is re-engaged with the lower plate one.

[0016] The opening and closing mechanism also includes a scraper bar, the middle part of which is sleeved and fixedly connected to the outer wall of the stirring shaft, and when the upper plate is lifted, the lower surface of the scraper bar is in contact with the upper surface of the upper plate.

[0017] The opening and closing mechanism comprises a lower plate 2 and an upper plate 2, wherein the lower plate 2 and the upper plate 2 are composed of two symmetrical quarter sectors, and the discharge port is the gap between the two quarter sectors.

[0018] The present invention provides an automatic fertilization device that combines bacterial agents with fertilizers. It has the following beneficial effects:

[0019] 1. The present invention uses a spreading disc arranged below the discharge port, which is driven by a rotating device to rotate synchronously in opposite directions. After the material falls into the spreading disc, it is evenly scattered under the action of centrifugal force, ensuring that the bacterial agent and fertilizer can cover the farmland widely and evenly, avoiding excessive or insufficient local fertilization, and helping crops to absorb nutrients evenly.

The operator does not need to operate the discharge valve additionally, and can control the discharging timing by adjusting the direction of the stirring motor, thereby simplifying the operating process and improving the fertilization efficiency. In addition, the opening and closing mechanism can also be used to push the material at the discharge port, thereby improving the discharge efficiency and avoiding the occurrence of blockage of the discharge port.

[0020] 2. The stirring paddle in the stirring component of the present invention is spiral-shaped and has multiple through holes. The spiral structure helps the material to be fully turned in the batching tank, so that the bacterial agent and the fertilizer are evenly mixed. The through holes can reduce the stirring resistance, prevent the material from agglomerating and clogging due to excessive extrusion, and ensure the accuracy and smoothness of the batching. The scraper fits tightly against the inner wall of the batching tank. When the stirring shaft rotates, the scraper can scrape off the material attached to the tank wall to avoid material residue, further ensure the integrity of the ingredients, and maintain the accurate ratio of the bacterial agent and the fertilizer each time the material is discharged. The inner wall of the batching tank, the outer surface of the stirring paddle and the outer wall of the scraper are all coated with Teflon coating. Teflon has an extremely low surface friction coefficient and excellent chemical stability. It can not only reduce the adhesion between the material and the surface of the equipment, making the material transportation smoother, but also prevent the chemical components in the bacterial agent and fertilizer from corroding the equipment, extend the service life of the device, and adapt to bacterial agents and fertilizers of various components.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Embodiment 1

[0034] Please see attached Figure 1 -Attached Figure 7The embodiment of the present invention provides an automatic fertilizing device for combining microbial agent with fertilizer, comprising a batching tank 1, a stirring motor 2 is fixedly connected to the top of the batching tank 1, a stirring shaft 3 is arranged inside the batching tank 1, the top of the stirring shaft 3 is fixedly connected to the output end of the stirring motor 2, an opening and closing mechanism is arranged at the bottom, a stirring component is arranged on the outer wall of the stirring shaft 3, the bottom wall of the batching tank 1 is open, the bottom outer wall of the opening and closing mechanism is embedded in and fixedly connected to the inner wall of the opening, two discharge ports 5 are symmetrically arranged on the bottom wall of the opening and closing mechanism, and a sowing disc 6 is arranged below the two discharge ports 5 in a one-to-one correspondence, and the sowing disc 6 is driven by a rotating device to rotate synchronously in opposite directions. When the stirring motor 2 rotates forward, the two discharge ports 5 are isolated from the inside of the batching tank 1, and when the stirring motor 2 rotates reversely, the two discharge ports 5 are connected to the inside of the batching tank 1, and the mixture of the microbial agent and the fertilizer falls into the sowing disc 6 from the discharge port 5 and is thrown out under the action of centrifugal force.

[0035] The rotating equipment adopts a high-precision gear transmission system to ensure that the speed synchronization error of the two spreading discs 6 is controlled within a very small range, so that the materials can be evenly and stably thrown out under the action of centrifugal force. The disk shape of the spreading disc 6 has been aerodynamically optimized, and is shallow-disc-shaped with slightly upward guide wings on the edge. This design can guide the material to spread along a predetermined trajectory, avoid the material from being concentrated at a certain point, achieve extensive and accurate coverage of the farmland, and ensure that the crops absorb nutrients evenly.

[0036] The spreading disc 6 arranged below the discharge port 5 is driven by a rotating device to rotate synchronously in opposite directions. After the material falls into the spreading disc 6, it is evenly thrown out under the action of centrifugal force, ensuring that the bacterial agent and fertilizer can cover the farmland widely and evenly, avoiding excessive or insufficient local fertilization, and helping crops to absorb nutrients evenly. At the same time, through the setting of the opening and closing mechanism, the forward and reverse rotation of the stirring motor 2 is used to realize the connection or isolation between the discharge port 5 and the inside of the batching tank 1, effectively integrating the stirring and discharging functions. The operator does not need to operate the discharge valve additionally, and only needs to adjust the direction of the stirring motor 2 to control the discharging time, simplifying the operation process and improving the fertilization efficiency. In addition, the opening and closing mechanism can also realize the promotion of the material at the discharge port 5, improve the discharging efficiency, and avoid the occurrence of blockage of the discharge port 5.

[0037] The outer wall of the batching tank 1 is sleeved and fixedly connected with a support frame 7, the outer wall of the support frame 7 is fixedly connected to the lifting end of the elevator 8, and the bottom of the elevator 8 is fixedly connected to the tail of the trailer bucket 9, so that the batching tank 1 is located outside the tail of the trailer bucket 9.

[0038] The height of the batching tank 1 is adjusted by the lift 8, thereby achieving the adjustment of the spreading area.

[0039] Two storage bins 10 are also installed on the trailer bucket 9, one storage bin 10 is used to hold fertilizers, and the other storage bin 10 is used to hold microbial agents. A conveying auger 11 is set up between the storage bin 10 and the elevator 8, and two receiving hoppers 12 are fixedly connected to the bottom of the elevator 8. The output ends of the two receiving hoppers 12 are respectively connected to the two feed ports at the top of the batching tank 1 through telescopic pipes 13. The discharge end of the conveying auger 11 is located above the feed end of the receiving hopper 12, and the feed end of the conveying auger 11 is located at the bottom of the storage bin 10.

[0040] The two storage bins 10 installed on the trailer bucket 9 are used to hold fertilizers and microbial agents respectively. The storage bin 10 adopts a double-layer insulation structure. The inner layer is food-grade stainless steel to ensure that the materials are not contaminated. The outer layer is a heat-insulating material, which can effectively isolate the influence of the external temperature on the microbial agent and maintain its activity stability. A conveying auger 11 is set up between the storage bin 10 and the elevator 8. The feeding end of the conveying auger 11 is located at the bottom of the storage bin 10. Through the conical collecting hopper, it is ensured that the material can smoothly enter the spiral blade area to avoid material residue. The two receiving hoppers 12 fixedly connected at the bottom of the elevator 8 adopt a funnel-shaped design, and their output ends are connected to the two feeding ports at the top of the batching tank 1 through the telescopic tube 13. The telescopic tube 13 has good flexibility and sealing, and can adjust the length adaptively according to the lifting and lowering of the batching tank 1, so as to realize accurate and efficient material transportation between the storage bin 10 and the batching tank 1.

[0041] The stirring component includes a stirring paddle 4 . The stirring paddle 4 is in a spiral structure and has a plurality of through holes 401 evenly opened on the slurry. The inner side of the stirring paddle 4 is fixedly connected to the outer wall of the stirring shaft 3 .

[0042] The stirring blade 4 is in a spiral structure, so that the material forms a three-dimensional rolling effect in the batching tank 1, accelerating the mixing process of the microbial agent and the fertilizer. The sizes of the multiple through holes 401 evenly opened have been strictly measured and calculated, which can not only ensure that the material has good fluidity during the stirring process and prevent the material from being hardened due to excessive local pressure, but also reduce the stirring resistance to a certain extent and reduce the energy consumption of the stirring motor 2. In addition, the existence of the through hole 401 also provides a channel for air to enter the material, which is conducive to maintaining the aerobic breathing environment of the microorganisms in the microbial agent and ensuring its activity.

[0043] The stirring component also includes a scraper 402 , one side of the scraper 402 is in contact with the inner wall of the mixing tank 1 , and the other side is fixedly connected to the outer wall of the stirring shaft 3 via a cross bar 403 .

[0044] The scraper 402 is made of a rubber composite material with high wear resistance and flexibility, which will not scratch the inner wall of the batching tank 1 and can adapt to slight deformation of the tank wall.

[0045] The inner wall of the batching tank 1, the outer surface of the stirring paddle 4 and the outer wall of the scraper 402 are all coated with Teflon coating.

[0046] Teflon coating has excellent non-stick, corrosion resistance and low friction coefficient characteristics. For environmentally sensitive and easily contaminated materials such as bacterial agents, Teflon coating can effectively prevent them from chemically reacting with the tank and stirring parts, maintaining the purity and activity of the bacterial agent. At the same time, when handling fertilizers, especially some fertilizers containing corrosive ingredients, the coating can greatly extend the service life of equipment components and reduce maintenance costs and replacement frequency.

[0047] The opening and closing mechanism includes a lower plate 14 and an upper plate 15. The outer wall of the lower plate 14 is embedded in and fixedly connected to the inner wall of the bottom opening of the batching tank 1. The lower plate 14 is provided with two symmetrical spiral inclined surfaces. The two discharge ports 5 are respectively located at the lowest points of the two spiral inclined surfaces. The middle part of the lower plate 14 is rotatably connected to the bottom end of the stirring shaft 3. The lower part of the upper plate 15 is a structure that is mutually embedded with the lower plate 14. The center of the lower plate 14 is respectively provided with a one-way bearing 16 and a one-way bearing 2 17 from top to bottom. The outer wall of the stirring shaft 3 is fixedly connected with a convex strip 18, which is located between the one-way bearing 16 and the one-way bearing 2 17. The outer wall of the one-way bearing 16 and the outer wall of the one-way bearing 2 17 are respectively fixedly connected to the upper plate 15. The inner wall, the inner wall of the one-way bearing 16 and the inner wall of the one-way bearing 2 17 are respectively provided with a groove 1601 and a groove 2 1701 corresponding to the convex strip 18. When the upper plate 15 is engaged with the lower plate 14, the convex strip 18 is inserted into the groove 1601, and the stirring shaft 3 rotates freely in the forward direction. When the stirring shaft 3 rotates in the reverse direction, the one-way bearing 16 is locked, driving the upper plate 15 to reverse. The upper plate 15 is lifted under the action of the spiral slope, the convex strip 18 is separated from the groove 1601 and inserted into the groove 2 1701. At this time, the stirring shaft 3 rotates freely in the reverse direction. When rotating forward, the one-way bearing 2 17 is locked, driving the upper plate 15 to rotate forward. Under the action of gravity, the upper plate 15 is re-engaged with the lower plate 14.

[0048] The opening and closing mechanism also includes a scraper bar 19, the middle part of which is sleeved and fixedly connected to the outer wall of the stirring shaft 3, and when the upper plate 15 is lifted, the lower surface of the scraper bar 19 fits with the upper surface of the upper plate 15.

[0049] When the stirring shaft 3 rotates in the opposite direction to lift the upper plate 15, the lower surface of the scraper bar 19 is closely attached to the upper surface of the upper plate 15. The material is selected to be engineering plastic with a certain hardness and a smooth surface, which can effectively scrape off the materials remaining on the upper plate 15 to prevent the accumulation of materials from affecting the fall of the upper plate 15 and the subsequent discharge. At the same time, guide grooves are designed on both sides of the scraper bar 19, and the scraped materials can slide along the guide grooves into the discharge port 5, further reducing material waste and clogging risks.

A one-way bearing 3 22 and a linkage ring 23 are respectively arranged at the center of the upper plate 21 from top to bottom, and a convex strip 24 is fixedly connected to the outer wall of the stirring shaft 3, and the convex strip 24 is located between the linkage ring 23 and the one-way bearing 3 22. The outer wall of the linkage ring 23 and the outer wall of the one-way bearing 3 22 are respectively fixedly connected to the inner wall of the upper plate 21, and the linkage ring 23 is fixedly connected to the inner wall of the upper plate 21. The inner wall of the ring 23 and the inner wall of the one-way bearing three 22 are respectively provided with a groove three 2301 and a groove four 2201 corresponding to the convex strip two 24. When the upper plate two 21 is at the lowest point, the baffle 2101 fits against the edge of the lower plate two 20, and the upper plate two 21 covers and closes the discharge port 5. At this time, the convex strip two 24 is inserted into the groove four 2201, and the stirring shaft 3 rotates freely in the forward direction. When the stirring shaft 3 rotates in the reverse direction, the one-way bearing three 22 is locked, driving the upper plate two 21 to reverse, and is lifted up with the cooperation of the baffle 2101 and the inclined surface, so that the bottom end of the baffle 2101 is located on the upper surface of the lower plate two 20, the convex strip two 24 is separated from the groove four 2201, and is inserted into the groove three 2301. At this time, the forward and reverse rotations of the stirring shaft 3 both drive the upper plate two 21 to rotate synchronously. When the stirring shaft 3 rotates forward, the baffle 2101 falls into the discharge port 5. Under the action of gravity, the upper plate two 21 descends, and covers and closes the discharge port 5 again.

[0052] While the discharge port 5 is opened and closed, the upper plate 21 can also be used to continuously rotate in the opposite direction, so that the baffle 2101 scrapes and pushes the material into the discharge port 5, thereby avoiding blockage.
