Description

Technical Field

[0001] This invention relates to the technical field of mixing equipment, and in particular to a mixing equipment for organic fertilizer and microbial agents in organic agriculture. Background Technology

[0002] With the booming development of organic agriculture, the combined use of organic fertilizers and functional microbial agents has become an important technical means to improve soil vitality and promote crop growth. Evenly mixing microbial agents (usually powder or small granules) with organic fertilizers (usually granules or crushed straw, manure, etc.) to form bio-organic fertilizer is a key preliminary step to ensure the uniform distribution and effectiveness of the agents in the field.

[0003] Currently, the industry primarily relies on traditional mechanical mixing equipment for mixing organic fertilizers and microbial agents, such as the "Apparatus for Effectively Blending and Mixing Microbial Fertilizer and Organic Fertilizer" disclosed in Chinese Utility Model Patent Publication No. CN201921776467.X. This type of device typically includes a mixing tank, motor-driven stirring and cutting blades, and related humidification and heating components. Its working principle involves placing the two solid materials into the same container, where high-speed rotating mechanical blades shear and scatter them to achieve mixing.

[0004] However, the applicant discovered that this type of mechanical mixing method has the following insurmountable technical defects when applied to materials with vastly different properties, namely organic fertilizer and microbial inoculants: 1. Poor mixing uniformity and easy segregation: Due to the significant differences in particle size, density, and shape between organic fertilizer granules and microbial agent granules (organic fertilizer granules are typically millimeter to centimeter in size and have a high density; microbial agent powder is typically micrometer in size and has a low density), during and after mechanical stirring, the tiny microbial agent particles easily separate from the larger organic fertilizer granules due to gravity and inertia. These particles settle or aggregate at the bottom, corners, or between large particles of the mixing container, resulting in uneven mixing at both the macroscopic and microscopic levels. This directly leads to a large dispersion in the distribution of microbial agents in the final product, severely affecting the application effect.

[0005] 2. High risk of impaired microbial activity: Mechanical stirring, especially high-speed cutting and mixing, generates strong shear forces and localized high temperatures. The live microorganisms (such as bacteria and fungal spores) in functional microbial agents are highly sensitive to mechanical shear and thermal effects. Violent mechanical action can lead to cell rupture and spore structure damage, significantly reducing the survival rate and activity of the agent, making the mixing process itself a step that weakens product efficacy.

[0006] 3. Material Residue and Cross-contamination: Moist organic fertilizer and fine microbial agent powder can easily adhere to the inner wall of the mixing tank, the mixing shaft, and the blades, forming residues. These residues are not easy to clean completely and may become a source of contamination in subsequent batches of production, affecting the purity and strain specificity of different batches of products.

[0007] 4. High energy consumption and efficiency need improvement: To achieve a certain degree of mixing, traditional equipment requires high-power motors for a long time of stirring, resulting in high energy consumption. Moreover, for the mixing scenario of "small amount of microbial agent" and "large amount of organic fertilizer", the time required to achieve uniform dispersion is even longer, resulting in low efficiency.

[0008] Although existing technologies attempt to simplify the process by integrating functions such as weighing, crushing, humidification, and temperature control into one tank, their core mixing mechanism remains unchanged. Therefore, they cannot fundamentally solve the problems of poor mixing uniformity and protection of biological activity caused by differences in the physical properties of materials.

[0009] Therefore, there is an urgent need in this field for an innovative mixing technology and equipment that can achieve efficient and uniform micro-mixing between trace amounts of lightweight microbial agents and large amounts of heavy organic fertilizer particles without relying on high-intensity mechanical shearing, while maximizing the preservation of microbial activity. This constitutes the technical problem to be solved by this invention. Summary of the Invention

[0010] To solve the above-mentioned technical problems, the present invention provides an organic agricultural fertilizer and microbial agent mixing device.

[0011] This invention discloses an organic fertilizer and microbial inoculant mixing device, comprising a mixing tank, fixed bases, supports, a controller, electromagnetic vibrators, and a base. Multiple sets of fixed bases are arranged on the outer wall of the mixing tank, and a set of supports is respectively arranged at the bottom end of each set of fixed bases. The bottom end of each set of supports is connected to the top end of the base. The top end of the base is equipped with a controller. Multiple sets of electromagnetic vibrators are arranged on the outer wall of the mixing tank. The device also includes: The No. 1 feeding assembly, which is mounted on the base, is used to deliver the charged microbial agent particles into the mixing tank. The second feeding assembly, installed at the top of the mixing tank, is used to transport organic fertilizer granules into the mixing tank. A discharge assembly, installed at the bottom of the mixing tank, is used for the external discharge of the mixed materials; The No. 1 feeding component, No. 2 feeding component, and discharge component are all electrically connected to the controller. During operation, the operator activates the No. 1 feeding component via the controller to deliver the charged microbial agent granules into the mixing tank. The microbial agent granules are sprayed upwards from the bottom inside the mixing tank. The No. 2 feeding component is then activated to deliver organic fertilizer granules into the mixing tank, where they fall downwards. The rising microbial agent granules are attracted to the falling organic fertilizer granules by their charge. Simultaneously, multiple electromagnetic vibrators are activated to ensure the attracted microbial agent granules and organic fertilizer granules gather at the bottom of the mixing tank, preventing them from adhering to the inside. After mixing, the operator operates the discharge component to discharge the charged mixture. Because the microbial agent is attracted to the corresponding organic fertilizer granules by charge, the mixing uniformity at both the macroscopic and microscopic levels is improved. This also avoids damage to the microbial agent caused by the strong shearing force and localized high temperature generated by high-speed cutting and stirring.

[0012] Preferably, the first feeding assembly includes a support frame, a centrifugal fan, a first material bin, a first conveying pipe, a venturi tube, a second conveying pipe, support rods, and a spreading frustum. The support frame and centrifugal fan are mounted on the top of the base. The first material bin is mounted on the top of the support frame. The first conveying pipe is mounted on the output end of the centrifugal fan. The bottom output end of the first material bin is connected to the outer wall of the first conveying pipe. The output end of the first conveying pipe is connected to the input end of the venturi tube. The output end of the venturi tube is connected to the input end of the second conveying pipe. The output end of the second conveying pipe extends into the mixing tank. Multiple sets of support rods are mounted on the top of the output end of the second conveying pipe. A spreading frustum is mounted on the top of each support rod. The bottom of the spreading frustum is conical. A corona discharge ring is embedded in the inner wall of the output end of the first conveying pipe. The discharge ring is electrically connected to the controller. The controller activates the corona discharge ring to discharge, which in turn starts the centrifugal fan, allowing outside air to enter the No. 1 conveying pipe. The microbial agent particles inside the No. 1 material box are then conveyed by the airflow within the No. 1 conveying pipe. As the microbial agent particles pass through the corona discharge ring, they carry a negative charge and enter the Venturi tube, increasing the conveying pressure. This also prevents the negatively charged microbial agent particles from adhering to the inner walls of the Venturi tube and the No. 2 conveying pipe. When the negatively charged microbial agent particles are sprayed out through the No. 2 conveying pipe, they are sprayed upwards in a curtain shape with the help of the spreading platform, making full contact with the descending organic fertilizer particles. The microbial agent particles adsorb the descending organic fertilizer particles through their negative charge, achieving uniform mixing of materials both macroscopically and microscopically.

[0013] Preferably, the second feeding assembly includes a second material box, a conveying pipe, a motor, a rotating shaft, spiral blades, a turntable, and guide plates. The output end of the second material box is connected to the input end of the conveying pipe. The output end of the conveying pipe passes through the top of the mixing tank and extends into the interior of the mixing tank. The conveying pipe is fixedly connected to the mixing tank. A motor is installed at the top of the second material box, and a rotating shaft is installed at the output end of the motor. The bottom end of the rotating shaft passes through the second material box and the conveying pipe and extends into the interior of the mixing tank. Spiral blades are installed on the outer wall of the rotating shaft, and the spiral blades are located inside the conveying pipe. A turntable is installed at the bottom end of the rotating shaft, and the turntable is shaped like a frustum. The turntable is equipped with multiple sets of guide plates at equal intervals. In use, organic fertilizer granules are stored inside the No. 2 material bin. The motor is started, which causes the rotating shaft to drive the spiral blades to rotate. The electric push rod stirs the organic fertilizer granules inside the No. 2 material bin to prevent blockage. At the same time, the spiral blades, in conjunction with the conveying pipe, transport the organic fertilizer granules. The organic fertilizer granules fall onto the turntable through the output end of the conveying pipe. Simultaneously, the rotating shaft drives the turntable to rotate synchronously, which causes the multiple sets of guide plates to scatter the organic fertilizer granules on the turntable in a curtain-like manner, improving the full mixing of organic fertilizer granules and charged microbial agent granules and increasing mixing efficiency.

[0014] Preferably, the discharge assembly includes a first shaft pin, a sealing plate, a U-shaped clamping plate, a second shaft pin, a lead screw, a wing nut, and a drive assembly. The sealing plate is hinged to the output end of the mixing tank via the first shaft pin. The mixing tank is equipped with a U-shaped clamping plate. The lead screw is hinged to the sealing plate via the second shaft pin. The lead screw is threadedly connected to the wing nut. A drive assembly is provided between the sealing plate and the base. The drive assembly is electrically connected to the controller. In use, the operator operates the drive assembly through the controller to seal the output end of the mixing tank with the sealing plate. Then, the operator moves the lead screw into the inside of the U-shaped clamping plate with the cooperation of the second shaft pin. After that, the operator rotates the wing nut, and the bottom end of the wing nut presses against the top end of the U-shaped clamping plate, thereby completing the secondary fixation of the sealing plate and improving the sealing performance of the output end of the mixing tank.

[0015] Preferably, the drive assembly includes a first hinge seat, a second hinge seat, and an electric push rod. The first end of the electric push rod is hinged to the top of the base via the first hinge seat, and the second end of the electric push rod is hinged to the bottom of the sealing plate via the second hinge seat. The electric push rod is electrically connected to the controller. The operator operates the electric push rod to extend via the controller, thereby causing the electric push rod to drive the sealing plate to seal the output end of the mixing tank under the cooperation of the first and second hinge seats, improving the ease of operation.

[0016] Preferably, it also includes a cover plate, a handle, and a hinge. The cover plate is hinged to the No. 1 material box via the hinge, and the cover plate is provided with a handle. The worker holds the handle and opens the cover plate with the help of the hinge. The worker pours two microbial agent granules into the No. 1 material box, and then the cover plate reseals the top of the No. 1 material box to prevent impurities from entering the support frame and improve protection.

[0017] Preferably, a reinforcing rod is also included, and a reinforcing rod is provided between the second material box and the mixing tank; the second material box and the mixing tank are strengthened by the reinforcing rod, thereby improving the connection strength between the second material box and the mixing tank and increasing the service life.

[0018] Preferably, the mixing tank is made of high-strength engineering plastic; the use of high-strength engineering plastic in the mixing tank avoids charge conduction of the negatively charged microbial agent and improves the adsorption of the microbial agent and organic fertilizer particles.

[0019] Preferably, the handle is provided with a grip sleeve; the operator grips the handle with the grip sleeve to reduce the chance of the handle slipping.

[0020] Preferably, a sealing gasket is provided on the sealing plate; when the electric push rod extends, the sealing plate seals the bottom output end of the mixing tank, and the sealing gasket seals the gap between the sealing plate and the mixing tank, thereby improving the sealing performance.

[0021] Compared with the prior art, the beneficial effects of this invention are as follows: In use, the operator activates the first feeding component through the controller to deliver the charged microbial agent particles into the mixing tank. The microbial agent particles are sprayed from bottom to top inside the mixing tank. The second feeding component is then activated to deliver the organic fertilizer particles into the mixing tank. The organic fertilizer particles fall from top to bottom inside the mixing tank. The rising microbial agent particles are attracted to the falling organic fertilizer particles by charge. At the same time, multiple sets of electromagnetic vibrators are activated to vibrate, thereby causing the attracted microbial agent particles and organic fertilizer particles to gather at the bottom of the inner side of the mixing tank, preventing them from adhering to the inner side of the mixing tank. After mixing is completed, the operator operates the discharge component to discharge the charged mixture. Because the microbial agent is attracted to the corresponding organic fertilizer particles by charge, the mixing uniformity at both the macroscopic and microscopic levels is improved. At the same time, the strong shearing force and local high temperature generated by high-speed cutting and stirring are avoided from damaging the microbial agent. Attached Figure Description

The second feeding assembly is installed at the top of the mixing tank 101 and is used to transport organic fertilizer granules into the mixing tank 101. A discharge assembly, installed at the bottom of the mixing tank 101, is used for the external discharge of the mixed materials; Among them, the No. 1 feeding component, the No. 2 feeding component, and the discharge component are all electrically connected to the controller 104; The first feeding assembly includes a support frame 201, a centrifugal fan 202, a first material bin 203, a first conveying pipe 204, a venturi tube 205, a second conveying pipe 206, a support rod 207, and a spreading frustum 208.

The second feeding assembly includes a second material bin 301, a conveying pipe 302, a motor 303, a rotating shaft 304, a spiral blade 305, a turntable 307, and a guide plate 308. The output end of the second material bin 301 is connected to the input end of the conveying pipe 302. The output end of the conveying pipe 302 passes through the top of the mixing tank 101 and extends into the interior of the mixing tank 101. The conveying pipe 302 is fixedly connected to the mixing tank 101. The motor 303 is installed at the top of the second material bin 301. The output end of 303 is provided with a rotating shaft 304.

The microbial agent granules adsorb the falling organic fertilizer granules through negative charge, achieving uniform mixing of materials at both the macroscopic and microscopic levels. Example

[0028] In this embodiment, the operator holds handle 210 and opens cover 209 with the help of hinge 211. Two microbial agent granules are poured into the first material bin 203. Then, cover 209 is resealed on top of the first material bin 203.

Then, the operator moves the lead screw 405 into the inner side of the U-shaped clamping plate 403 with the cooperation of the second shaft pin 404. Then, the wing nut 406 is rotated, and the bottom end of the wing nut 406 presses against the top end of the U-shaped clamping plate 403, thereby completing the secondary fixation of the sealing plate 402 and improving the sealing performance of the output end of the mixing tank 101.

[0029] The main functions achieved by this invention are: 1. The principle of "electrostatic adsorption" is applied to the mixing of two solid particles: organic fertilizer and microbial inoculant. By making the tiny inoculant particles negatively charged, they are actively and directionally adsorbed onto the surface of neutral or polarizable organic fertilizer particles in the mixing space.

[0030] 2. Embed the corona discharge ring into the inner wall of the No. 1 delivery pipe to minimize interference with the flow field. Utilize the high-speed airflow generated by the centrifugal fan to simultaneously achieve the delivery, dispersion, and anti-clogging of the bacterial agent, as well as the prevention of adsorption of charged particles onto the pipe wall. Increase the airflow velocity through the Venturi tube to optimize the delivery and atomization effect.

[0031] 3. The charged microbial agent particles are sprayed from bottom to top, while the organic fertilizer particles are scattered from top to bottom in a curtain-like manner, forming a particle curtain with counter-current flow. This greatly increases the probability and contact time of spatial contact between the two phase materials.

[0032] 4. The mixing tank is made of high-strength engineering plastic insulation material. An intermittent electromagnetic vibrator is installed on the outside of the mixing tank wall to easily peel off the limited material layer that is attached to the tank wall due to static electricity and van der Waals forces by using mechanical vibration.
