Description

Technical Field

[0001] This utility model relates to the field of water-soluble fertilizer mixing technology, and in particular to an agricultural biological water-soluble fertilizer mixing device. Background Technology

[0002] In agricultural production, the application of water-soluble fertilizers is becoming increasingly widespread. They dissolve rapidly in water, are more easily absorbed by crops, and enable integrated water and fertilizer management, thus improving fertilizer utilization. Agricultural bio-based water-soluble fertilizers, due to the addition of microbial agents and bioactive substances, offer numerous advantages such as soil improvement and enhanced crop resistance.

[0003] However, existing water-soluble fertilizer mixing equipment has significant drawbacks. Traditional open mixing methods expose the microbial agent to air for extended periods, causing the active ingredients to readily react with oxygen and microorganisms, leading to inactivation and significantly reducing the fertilizer's effectiveness. Furthermore, while traditional spiral mixing methods can achieve some mixing, materials of different densities are prone to stratification during the mixing process. In particular, trace elements and bioactive substances are difficult to distribute evenly throughout the fertilizer system, affecting the balanced absorption of nutrients by crops and consequently impacting crop growth and development. Therefore, we propose an agricultural biological water-soluble fertilizer mixing equipment to address these issues. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an agricultural biological water-soluble fertilizer mixing device.

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

[0006] An agricultural biological water-soluble fertilizer mixing device includes a mixing tank. A conveying hood is connected to the upper end of the mixing tank. A rotating mechanism is staggered and inclined on both sides of the upper end of the mixing tank. One end of the rotating mechanism is connected to a stirring rod. Multiple rectangular stirring blades and spiral stirring blades are evenly spaced on the circumference of the stirring rod. Four annular spray pipes are evenly fixed on the circumference of the mixing tank. One end of each annular spray pipe is connected to a conveying pipeline. One end of the conveying pipeline is connected to a nitrogen pipeline, a carbon dioxide pipeline, and a high-pressure gas pipeline. A first electric valve is installed on each of the nitrogen pipeline, carbon dioxide pipeline, and high-pressure gas pipeline.

[0007] Preferably, a conveying pipe is connected to the middle of the upper end of the conveying hood, and a discharge pipe is connected to the middle of the lower end of the mixing tank. A second electric valve is installed on both the discharge pipe and the conveying pipe.

[0008] Preferably, an exhaust pipe is connected to one side of the upper end of the material conveying hood.

[0009] Preferably, the rotating mechanism includes two drive motors that are tilted and fixed on both sides of the upper end of the mixing tank, with the two drive motors arranged alternately, and the output shaft of the drive motor is connected to one end of the stirring rod.

[0010] Preferably, each of the four annular nozzles is connected to both sides by two connecting pipes, and multiple spray holes are provided at equal intervals on the circumferential sidewall of the annular nozzle, and the spray holes are connected to the inside of the mixing tank.

[0011] Preferably, the delivery pipeline includes a gas delivery pipe connected to one side of one of the connecting pipes, a protective box is provided on one side of the mixing tank, a connector is fixed inside the protective box, one end of the gas delivery pipe is connected to one side of the connector, and one end of the nitrogen pipeline, carbon dioxide pipeline and high-pressure gas pipeline are connected to the other side of the connector.

[0012] In this invention, when mixing is required:

[0013] 1. Feeding stage: When water-soluble fertilizer needs to be mixed, the operator opens the second electric valve on the conveying pipe to transport the various raw materials of water-soluble fertilizer through the conveying pipe to the conveying hood and then into the mixing tank. During the feeding process, the conveying hood plays the role of buffering and guiding the material to ensure that the material can enter the mixing tank smoothly. At the same time, the exhaust pipe connected to one side of the upper end of the conveying hood can discharge the gas generated during the feeding process and maintain the gas pressure balance in the mixing tank.

[0014] 2. Mixing stage: After the raw materials enter the mixing tank, the drive motors that are tilted and fixed on both sides of the upper end of the mixing tank are started. Since the two drive motors are staggered, they drive the mixing rods to mix in an alternating manner. Multiple rectangular and spiral mixing blades are evenly distributed on the side wall of the mixing rods. The rectangular mixing blades can mix the materials laterally, while the spiral mixing blades can make the materials flow longitudinally. This staggered mixing method can effectively avoid the material stratification problem that is easy to occur in traditional spiral mixing and improve the uniformity of material mixing.

[0015] 3. Gas-assisted mixing stage: While stirring, open the first electric valve on the high-pressure gas pipeline. The high-pressure gas enters the four annular nozzles through the gas delivery pipe, connector, and connecting pipe. Multiple nozzles are evenly distributed on the side wall of the annular nozzle. The high-pressure gas is injected into the mixing tank through the nozzles to further disturb the material and improve the uniformity and thoroughness of the mixing. Afterwards, the first electric valves on the nitrogen and carbon dioxide pipelines can be opened as needed to introduce nitrogen and carbon dioxide into the mixing tank.

[0016] 4. Discharge stage: After mixing is completed, open the second electric valve on the discharge pipe, and the mixed water-soluble fertilizer is discharged from the mixing tank through the discharge pipe, completing the entire mixing process.

[0017] This utility model has the following advantages:

[0018] 1. This equipment adopts a relatively closed mixing environment and reduces the oxygen content in the mixing tank by introducing nitrogen and carbon dioxide, providing a more suitable survival environment for the microbial agent, increasing the survival rate of the microbial agent from 72% to 98%, ensuring the activity of the microbial agent in the water-soluble fertilizer, and thus better exerting the role of the microbial agent in improving soil and promoting crop growth.

[0019] 2. The staggered mixing rods, combined with rectangular and spiral mixing blades, and the high-pressure gas sprayed through the annular nozzle, effectively prevent material stratification, allowing trace elements and bioactive substances to be evenly distributed in the water-soluble fertilizer, ensuring the balanced absorption of various nutrients by crops and improving the fertilizer efficiency of the water-soluble fertilizer.

[0020] In summary, this invention ensures the activity of the microbial agent in the water-soluble fertilizer, allowing it to better play its role in improving soil and promoting crop growth. In addition, it avoids material stratification, enabling trace elements and bioactive substances to be evenly distributed in the water-soluble fertilizer, ensuring balanced absorption of various nutrients by crops and improving the fertilizer efficiency of the water-soluble fertilizer.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figure 1-4An agricultural biological water-soluble fertilizer mixing device includes a mixing tank 3. The upper end of the mixing tank 3 is connected to a conveying cover 6. The conveying cover 6 not only connects the conveying pipe 1 and the mixing tank 3, but also plays an important role in the feeding process. It helps to buffer the falling speed of the material and prevent the material from directly impacting the bottom of the mixing tank 3. At the same time, the inner wall of the conveying cover 6 can be made of a smooth material to better guide the material into the mixing tank 3.

[0028] The upper end of the mixing tank 3 is provided with a rotating mechanism that is staggered on both sides. One end of the rotating mechanism is connected to a stirring rod 17. Multiple rectangular stirring blades 16 and spiral stirring blades 18 are provided at equal intervals on the side wall of the stirring rod 17. The staggered and inclined arrangement allows the stirring rod 17 to cover a larger stirring range during the stirring process, avoiding the occurrence of stirring dead corners.

[0029] The rectangular stirring blade 16 is mainly responsible for lateral stirring of the material. Its shape and size are optimized to generate a large lateral force during rotation, ensuring thorough mixing of the material in the horizontal direction. The spiral stirring blade 18, on the other hand, can generate longitudinal flow of the material. Its spiral shape can guide the material to move upward or downward, breaking up the stratification of the material and further improving the uniformity of mixing.

[0030] Four annular nozzles 5 are fixed at equal intervals on the side wall of the mixing tank 3. One end of the annular nozzle 5 is connected to a conveying pipeline, and the other end of the conveying pipeline is connected to a nitrogen pipeline 11, a carbon dioxide pipeline 12, and a high-pressure gas pipeline 13. A first electric valve 15 is installed on each of the nitrogen pipeline 11, carbon dioxide pipeline 12, and high-pressure gas pipeline 13. The first electric valve 15 can precisely control the amount and time of each gas introduced, and can be flexibly adjusted according to different water-soluble fertilizer mixing requirements.

[0031] The upper middle part of the conveying hood 6 is connected to the conveying pipe 1, and the lower middle part of the mixing tank 3 is connected to the discharge pipe 8. Both the discharge pipe 8 and the conveying pipe 1 are equipped with a second electric valve 20. The second electric valve 20 can accurately control the feeding and discharging process, ensuring that the feeding and discharging operations are carried out at the appropriate time, thereby improving the mixing efficiency and product quality.

[0032] The upper side of the material conveying hood 6 is connected to an exhaust pipe 2. The function of the exhaust pipe 2 is to discharge the gas generated during the feeding process and maintain the air pressure balance in the mixing tank 3. It can be connected to a gas treatment device to purify the discharged gas and avoid pollution to the environment. A valve is installed on it.

[0033] The rotating mechanism includes drive motors 7 that are tilted and fixed on both sides of the upper end of the mixing tank 3. The two drive motors 7 are staggered. The output shaft of the drive motor 7 is connected to one end of the stirring rod 17. The two sides of the four annular nozzles 5 are connected by two connecting pipes 4. Multiple nozzle holes 19 are provided at equal intervals on the circumferential side wall inside the annular nozzles 5. The nozzle holes 19 are connected to the inside of the mixing tank 3. The connecting pipes 4 ensure that the gas can smoothly enter the annular nozzles 5 from the conveying pipeline. The size and distribution of the nozzle holes 19 are precisely calculated so that the gas can be sprayed into the mixing tank 3 at a suitable pressure and angle to achieve the best gas-assisted mixing effect.

[0034] The delivery pipeline includes a gas delivery pipe 9 connected to one side of one of the connecting pipes 4. A protective box 10 is provided on one side of the mixing tank 3. A connector 14 is fixed inside the protective box 10. One end of the gas delivery pipe 9 is connected to one side of the connector 14. One end of the nitrogen pipeline 11, the carbon dioxide pipeline 12, and the high-pressure gas pipeline 13 are connected to the other side of the connector 14. The protective box 10 protects the connector 14 to prevent it from being damaged by external factors and to ensure the stability and safety of gas delivery.

[0035] In this invention, when mixing is required:

[0036] 1. Feeding stage: When water-soluble fertilizer needs to be mixed, the operator opens the second electric valve 20 on the conveying pipe 1 to transport the various raw materials of water-soluble fertilizer through the conveying pipe 1 to the conveying hood 6, and then into the mixing tank 3. During the feeding process, the conveying hood 6 plays the role of buffering and guiding the material to ensure that the material can enter the mixing tank 3 smoothly. At the same time, the exhaust pipe 2 connected to the upper side of the conveying hood 6 can discharge the gas generated during the feeding process and maintain the gas pressure balance in the mixing tank 3.

[0037] 2. Mixing stage: After the raw materials enter the mixing tank 3, the drive motors 7, which are tilted and fixed on both sides of the upper end of the mixing tank 3, are started. Since the two drive motors 7 are staggered, they drive the mixing rods 17 to perform staggered mixing. Multiple rectangular mixing blades 16 and spiral mixing blades 18 are evenly distributed on the side wall of the mixing rods 17. The rectangular mixing blades 16 can perform transverse mixing of the material, while the spiral mixing blades 18 can make the material flow longitudinally. This staggered mixing method can effectively avoid the material stratification problem that is easy to occur in traditional spiral mixing and improve the uniformity of material mixing.

[0038] 3. Gas-assisted mixing stage: While stirring, open the first electric valve 15 on the high-pressure gas pipeline 13. The high-pressure gas enters the four annular nozzles 5 through the gas delivery pipe 9, connector 14, and connecting pipe 4. Multiple nozzles 19 are evenly distributed on the side wall of the annular nozzles 5. The high-pressure gas is sprayed into the mixing tank 3 through the nozzles 19 to further disturb the material and improve the uniformity and thoroughness of mixing. Afterwards, the first electric valves 15 on the nitrogen pipeline 11 and carbon dioxide pipeline 12 can be opened as needed to introduce nitrogen and carbon dioxide into the mixing tank 3.

[0039] 4. Discharge stage: After mixing is completed, open the second electric valve 20 on the discharge pipe 8, and the mixed water-soluble fertilizer is discharged from the mixing tank 3 through the discharge pipe 8, completing the entire mixing process.

[0040] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
