Description

Technical Field

[0001] This application relates to the field of equipment for applying microbial agents, and more particularly to a microbial agent premixing device. Background Technology

[0002] With the popularization of green agriculture concepts and the promotion of large-scale planting models, microbial agents (such as biological nitrogen-fixing agents and disease-resistant and growth-promoting agents) have become key products for improving crop yield and quality due to their ability to reduce the use of chemical fertilizers and pesticides and improve soil microecology. Drip irrigation technology, with its advantages of water conservation, fertilizer saving, and precise delivery, is gradually becoming the mainstream supporting method for the field application of microbial agents.

[0003] Currently, the mixing of microbial agents and the liquid to be mixed is still mainly done manually. Growers pour a measured amount of microbial agent (mostly powder or concentrate) into a simple mixing tank, add a certain amount of the liquid to be mixed, and then manually stir with a hand-held stirring rod. After initial mixing, the mixture is poured into the liquid source tank or inlet of the drip irrigation system. In some cases, microbial agent granules or concentrate are directly sprinkled into the liquid source of the drip irrigation system, relying on the natural impact of the liquid flow to achieve mixing. However, this manual method has significant technical drawbacks. Because the stirring force and frequency are difficult to maintain consistently, it easily leads to the agglomeration of microbial agent powder into lumps or localized aggregation of concentrate, resulting in an uneven concentration of microbial agent in the mixture. This uneven mixture, entering the field through the drip irrigation system, can cause an imbalance in the crop root microbial community in areas with excessively high concentrations, leading to the risk of seedling burn, while areas with excessively low concentrations will not be able to exert the growth-promoting and disease-resistant effects of the microbial agent, thus affecting the application effect of the microbial agent.

[0004] Therefore, there is an urgent need for a mixing device to ensure that the bacterial agent is mixed evenly before drip irrigation, thereby improving the application effect of the bacterial agent. Utility Model Content

[0005] The purpose of this application is to address the above problems by providing a microbial agent premixing device, which allows the microbial agent to be mixed evenly before drip irrigation, thereby improving the application effect of the microbial agent.

The descriptions in this section are merely illustrative and explanatory, and should not be construed as limiting the scope of protection of this application. Specifically, the described embodiments are only some embodiments of this application, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort should fall within the scope of protection of this invention.

[0021] It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or apparatus.

[0022] As mentioned in the background section, in view of the problems in the prior art, this embodiment provides a microbial agent premixing device, comprising: Mixing container 1, which is used to contain the bacterial agent and the liquid to be mixed; A stirring mechanism 2 is disposed inside the mixing container 1 and is used to stir and mix the bacterial agent and the liquid to be mixed. A drive motor 3 is disposed on the outer wall of the mixing container 1 and is connected to the stirring mechanism 2 for driving the stirring mechanism 2 to rotate around its axis to stir and mix the bacterial agent and the liquid to be mixed. Adjustment component 4 is used to detect the rotational speed of the drive motor 3 and adjust the rotational speed.

[0023] For details, please refer to Figure 1The mixing container 1 is cylindrical with a hollow interior and closed bottom and top surfaces of its outer wall. The mixing container 1 contains the bacterial agent, the liquid to be mixed, and the stirring mechanism 2. The top surface of the outer wall of the mixing container 1 is equipped with the drive motor 3 and the adjustment component 4. The stirring mechanism 2 is used to stir and mix the bacterial agent and the liquid to be mixed. The drive motor 3 is fixedly connected to the top surface of the outer wall of the mixing container 1 via a second mounting plate 9. The fixed connection between the drive motor 3 and the second mounting plate 9, and between the second mounting plate 9 and the top surface of the outer wall of the mixing container 1, can be welding or connected by screws, etc., without specific limitation. The drive motor 3 and the stirring mechanism 2 are connected by magnetic coupling, driving the stirring mechanism 2 to rotate around its axis to stir and mix the bacterial agent and the liquid to be mixed. The drive motor 3 is equipped with a low-backlash planetary reducer with a reduction ratio of 50:1 to 100:1, which can proportionally reduce the high speed of the drive motor 3 to the low speed range required for stirring. The adjustment component 4 is used to detect and adjust the rotational speed of the drive motor 3. Furthermore, the mixing container 1 is designed as a cylinder to avoid sharp corners, protecting the activity of the bacterial agent from being sheared or impacted by sharp corners during stirring and thus preventing its deactivation. In addition, the device includes a main display panel 8, which displays parameters such as the rotational speed of the drive motor 3 and the temperature of the mixed solution, for observing the mixing state of the mixed solution.

[0024] The microbial agent premixing device described in this application includes a mixing container, a stirring mechanism, a drive motor, and an adjustment component. The mixing container is used to hold the microbial agent and the liquid to be mixed. The drive motor provides driving force to the stirring mechanism within the mixing container. The adjustment component can detect and adjust the speed of the drive motor. By adjusting the speed of the drive motor according to the different characteristics of the microbial agent, the stirring speed of the stirring mechanism is changed and kept stable, so that different types of microbial agents can be fully and evenly mixed with the liquid to be mixed, thereby improving the application effect of the microbial agent. This solves the problem of uneven concentration of microbial agent in the mixed liquid caused by manual stirring and avoids the situation where the application effect of the microbial agent is affected by uneven concentration of the mixed liquid.

[0025] In a preferred embodiment, the outer wall of the mixing container 1 is provided with a liquid inlet 11, a microbial agent inlet 12 and a liquid outlet 13. The liquid inlet 11 is used to input the liquid to be mixed into the mixing container 1, the microbial agent inlet 12 is used to input the microbial agent, and the liquid outlet 13 is used to output the mixed solution formed by the liquid to be mixed and the microbial agent after being stirred by the stirring mechanism 2.

[0026] Specifically, such as Figure 1As shown, the mixing container 1 has a liquid inlet 11, a bacterial agent inlet 12, and a liquid outlet 13 on its outer side. The liquid inlet 11 has an inlet pipe for inputting the liquid to be mixed, and a filter screen is installed in the inlet pipe. The filter screen is fixedly connected to the inlet pipe by welding or other means to filter impurities in the liquid to be mixed. The bacterial agent inlet 12 has a funnel for inputting the bacterial agent. The liquid outlet 13 is located on the outer side of the mixing container 1 and near its bottom. An outlet pipe is installed at the liquid outlet 13 for outputting the mixed solution formed by the liquid to be mixed and the bacterial agent after being stirred by the stirring mechanism 2. The inlet pipe, the funnel, and the outlet pipe are detachably connected to the mixing container 1 for easy cleaning. Furthermore, switches can be installed on the inlet pipe and the outlet pipe to control the flow or shut-off of the liquid to be mixed and the mixed solution, respectively. The inlet pipe is also equipped with a flow meter 14, which is used to measure the flow rate of the liquid to be mixed in order to control the concentration of the mixture of the liquid to be mixed and the bacterial agent. The flow meter 14 can be an electromagnetic flow meter or a turbine flow meter, and no specific limitation is made here.

[0027] In a preferred embodiment, the device further includes a magnetic coupling assembly disposed between the drive motor 3 and the stirring mechanism 2. The magnetic coupling assembly includes an outer magnetic rotor 51 and an inner magnetic rotor 52. The outer magnetic rotor 51 is disposed outside the mixing container 1 and fixedly connected to the output shaft of the drive motor 3. The inner magnetic rotor 52 is disposed inside the mixing container 1 and fixedly connected to the stirring mechanism 2. This allows the drive motor 3 to rotate, thereby driving the outer magnetic rotor 51 to rotate. The inner magnetic rotor 52 is then rotated through magnetic coupling, which in turn drives the stirring mechanism 2 to rotate.

[0028] Specifically, such as Figure 1 and Figure 3As shown, the magnetic coupling assembly is disposed between the drive motor 3 and the stirring mechanism 2. The magnetic coupling assembly includes an outer magnetic rotor 51 and an inner magnetic rotor 52. The outer magnetic rotor 51 is disposed outside the mixing container 1 and fixedly connected to the output shaft of the drive motor 3. The inner magnetic rotor 52 is disposed inside the mixing container 1 and fixedly connected to the stirring mechanism 2. The drive motor 3 rotates, causing the outer magnetic rotor 51 to rotate. Through magnetic coupling, the inner magnetic rotor 52 rotates, thereby driving the stirring mechanism 2 to rotate. The magnetic coupling refers to the phenomenon of energy, force, or information transfer between two or more magnetic fields through magnetic field interaction, which can cause mutual influence between magnets (or current-carrying conductors) in different spaces without physical contact. The outer magnetic rotor 51 and the inner magnetic rotor 52 are completely isolated and sealed by the mixing container 1, achieving leak-free and contactless transmission, which can prevent leakage of the mixed solution.

[0029] In a preferred embodiment, the adjustment component 4 includes an encoder 41 and an adjuster 42. The encoder 41 is disposed outside the mixing container 1 and is fixedly connected to the drive motor 3 and rotates synchronously with the drive motor 3. It is used to detect the rotation speed of the drive motor 3 and transmit it to the adjuster 42. The adjuster 42 is used to calculate the difference between the received rotation speed of the drive motor 3 and a preset rotation speed, and adjust the rotation speed of the drive motor 3 according to the difference.

[0030] Specifically, such as Figure 1 As shown, the encoder 41 is fixedly connected to the drive motor 3 outside the mixing container 1 and rotates synchronously with the drive motor 3. It is used to detect the rotational speed of the drive motor 3 and transmit it to the regulator 42. In this embodiment, an encoder with a resolution of 14 to 16 bits can be selected. The regulator 42 is located on the top surface of the outer wall of the mixing container 1. The regulator 42 is used to calculate the difference between the received rotational speed of the drive motor 3 and a preset rotational speed, and to increase or decrease the rotational speed of the drive motor 3 according to the difference, so that the difference between the rotational speed of the drive motor 3 and the preset rotational speed is stable within ±2%. The regulator 42 is equipped with an OLED screen, which can be a touch screen, for inputting the preset rotational speed. The preset rotational speed is a rotational speed that matches the mixing requirements of different bacterial agents. The regulator 42 can be a microcontroller or a PLC.

[0031] In a preferred embodiment, the device further includes an auxiliary drive assembly 6 disposed on the outer wall of the mixing container 1. The auxiliary drive assembly 6 includes a manual adjustment member 61, a transmission belt 62, and an overrunning clutch 63. The manual adjustment member 61 is disposed on the outer wall of the mixing container 1, and the overrunning clutch 63 is disposed on the output shaft of the drive motor 3. The two ends of the transmission belt 62 are respectively sleeved on the outer wall of the output shaft 611 of the manual adjustment member 61 and the outer wall of the overrunning clutch 63. The drive motor 3 has a first state and a second state. When the drive motor 3 is in the first state, the drive motor 3 is energized and drives its output shaft to rotate in a first direction, and the overrunning clutch 63 remains stationary. When the drive motor 3 is in the second state, the drive motor 3 is de-energized, and the manual adjustment member 61 drives the overrunning clutch 63 through the transmission belt 62 to drive the output shaft of the drive motor 3 to rotate synchronously in a second direction. The first direction is opposite to the second direction.

[0032] Specifically, such as Figure 2 and Figure 5 As shown, the manual adjustment component 61 includes an output shaft 611, a bearing, a grip 612, and a connecting rod 613. The output shaft 611 is fixed to the adjuster 42 via the bearing. The output shaft 611 and the grip 612 of the manual adjustment component 61 are fixedly connected via the connecting rod 613, so that the output shaft 611 rotates synchronously when the grip 612 is rotated. The overrunning clutch 63 is fixed to the output shaft of the drive motor 3. Pulleys are provided on the outer walls of the output shaft 611 of the manual adjustment component 61 and the overrunning clutch 63. The two ends of the transmission belt 62 are respectively sleeved on the pulleys on the outer walls of the output shaft 611 and the overrunning clutch 63, so that the overrunning clutch 63 rotates synchronously when the output shaft 611 of the manual adjustment component 61 rotates.

[0033] The first state is when the drive motor 3 is energized. The drive motor 3 operates, and the driving force of its output shaft comes from the drive motor 3 itself. At this time, the drive motor 3 drives its output shaft to rotate in the first direction, and the overrunning clutch 63 remains stationary. The second state is when the drive motor 3 is de-energized. The drive motor 3 stops working, and the driving force of its output shaft comes from the manual adjustment component 61. Manually rotating the manual adjustment component 61 drives the overrunning clutch 63 via the transmission belt 62, causing the output shaft of the drive motor 3 to rotate synchronously in the second direction. This can be used when the drive motor 3 malfunctions, or for low-speed stirring of the bacterial agent and the liquid to be mixed, as well as for cleaning and emptying the mixing container 1. The first direction is opposite to the second direction; that is, when the first direction is clockwise, the second direction is counterclockwise; or when the first direction is counterclockwise, the second direction is clockwise. Furthermore, the fact that the overrunning clutch 63 only rotates in the second state can also prevent the output shaft of the drive motor 3 from driving the manual adjustment component 61 to rotate via the transmission belt 62, thus avoiding danger.

[0034] In a preferred embodiment, the stirring mechanism 2 includes: A stirring shaft 21 is disposed inside the mixing container 1 and coaxially fixedly connected to the end of the inner magnetic rotor 52 away from the outer magnetic rotor 51, and rotates synchronously with the inner magnetic rotor 52; a thrust bearing 22 is provided at the end of the stirring shaft 21 near the inner magnetic rotor 52, and the thrust bearing 22 is fixedly connected to the mixing container 1 through a first mounting plate 23. A stirring element 24 is disposed inside the mixing container 1. The stirring element 24 includes a first stirring blade 241 and a second stirring blade 242. The first stirring blade 241 is disposed at one end of the stirring shaft 21 near the inner magnetic rotor 52, and the second stirring blade 242 is disposed at one end of the stirring shaft 21 away from the inner magnetic rotor 52.

[0035] Specifically, such as Figure 3 As shown, the stirring shaft 21 is disposed inside the mixing container 1 and coaxially fixedly connected to the end of the inner magnetic rotor 52 away from the outer magnetic rotor 51, so that the stirring shaft 21 rotates synchronously when the inner magnetic rotor 52 rotates. A thrust bearing 22 is provided at the end of the stirring shaft 21 near the inner magnetic rotor 52. The thrust bearing 22 is used to withstand axial force and prevent the stirring shaft 21 from moving in its axial direction. The thrust bearing 22 is fixedly connected to the mixing container 1 by a first mounting plate 23. The fixed connection method can be welding or screw connection, etc., which is not specifically limited here.

[0036] The first stirring blade 241 is disposed at one end of the stirring shaft 21 near the inner magnetic rotor 52, and the second stirring blade 242 is disposed at one end of the stirring shaft 21 away from the inner magnetic rotor 52. Both the first stirring blade 241 and the second stirring blade 242 are fixedly connected to the stirring shaft 21 and are used to stir the bacterial agent and the liquid to be mixed. The two layers of stirring blades can also make the bacterial agent and the liquid to be mixed more evenly.

[0037] In a preferred embodiment, the first stirring blade 241 is an airfoil, with its blades forming a downward angle with the radial plane of the stirring shaft 21, which can drive the bacterial agent and the liquid to be mixed to move away from the inner magnetic rotor 52; the second stirring blade 242 is an airfoil, with its blades forming an upward angle with the radial plane of the stirring shaft 21, which can drive the bacterial agent and the liquid to be mixed to move towards the inner magnetic rotor 52, so that the liquid to be mixed and the bacterial agent in the mixing container 1 form turbulence.

[0038] Specifically, such as Figure 3 As shown, both the first stirring blade 241 and the second stirring blade 242 are airfoil-shaped blades, capable of generating axial flow at a relatively low speed while simultaneously stirring in the circumferential direction. Their lengths reach the inner wall of the mixing container 1, ensuring that both the bacterial agent and the liquid to be mixed within the radial range of the mixing container 1 are stirred, resulting in more thorough and uniform mixing. The first stirring blade 241 forms a downward angle with the radial plane of the stirring shaft 21, driving the bacterial agent and the liquid to be mixed away from the inner magnetic rotor 52. The second stirring blade 242 forms an upward angle with the radial plane of the stirring shaft 21, driving the bacterial agent and the liquid to be mixed closer to the inner magnetic rotor 52, creating turbulent flow between the bacterial agent and the liquid to be mixed, resulting in a more uniform mixture. Multiple blades are provided for both the first stirring blade 241 and the second stirring blade 242. In addition, the edges of the first stirring blade 241 and the second stirring blade 242 are rounded and the stirring speed is not too high to avoid tearing the bacterial agent and affecting its activity.

[0039] In a preferred embodiment, the stirring mechanism 2 further includes a baffle plate 25, which is fixedly installed on the inner wall of the mixing container 1.

[0040] Specifically, such as Figure 4As shown, the baffle 25 is used to agitate the regular flow formed by the first stirring blade 241 and the second stirring blade 242, so as to make the bacterial agent and the liquid to be mixed more evenly. The baffle 25 is rectangular and fixedly connected to the inner wall of the mixing container 1. A gap is provided between the baffle 25 and the inner wall of the mixing container 1 to avoid the formation of dead corners where no liquid flows, thereby improving the stirring and cleaning effects. In addition, the edges of the baffle 25 are rounded to avoid sharp corners damaging the bacterial agent and affecting its activity.

[0041] In a preferred embodiment, the mixing container 1 is made of a transparent material and is used to observe the mixing state and liquid level of the liquid to be mixed and the bacterial agent.

[0042] Specifically, such as Figure 1 As shown, the mixing container 1 is made of transparent material, such as transparent PC or glass, and is used to observe the mixing state and liquid level of the liquid to be mixed and the bacterial agent. Furthermore, the outer wall of the mixing container 1 can be double-layered, and the temperature of the mixed solution inside the mixing container can be lowered by pouring water or other liquids between the two layers.

[0043] In a preferred embodiment, the device further includes a temperature sensor 7 disposed on the inner wall of the mixing container 1 for measuring the temperature of the mixed solution.

[0044] Specifically, such as Figure 4 As shown, the device also includes a temperature sensor 7, which is fixedly connected to the inner wall of the mixing container 1. The temperature sensor 7 is used to measure the temperature of the mixed solution and output it to the main display panel 8 shown, so as to observe the temperature of the mixed solution in real time and avoid the inactivation of the bacterial agent due to excessive temperature.

[0045] The microbial agent premixing device provided in this application includes a mixing container, a stirring mechanism, a drive motor, and an adjustment component. The mixing container holds the microbial agent and the liquid to be mixed. The drive motor provides driving force to the stirring mechanism within the mixing container. The adjustment component detects and adjusts the speed of the drive motor. By adjusting the speed of the drive motor according to the different characteristics of the microbial agent, the stirring speed of the stirring mechanism is changed and kept stable, ensuring that different types of microbial agents are fully and evenly mixed with the liquid to be mixed. This improves the application effect of the microbial agent and solves the problem of uneven concentration of the microbial agent in the mixed solution caused by manual stirring, avoiding the impact of uneven concentration on the application effect of the microbial agent. Two layers of stirring blades create turbulent flow between the liquid to be mixed and the microbial agent mixture. The lengths of the first and second stirring blades can reach the inner wall of the mixing container. The baffle plate further improves the uniformity of the mixed solution by disturbing the regular flow formed by the first and second stirring blades. The first and second stirring blades and the baffle plate have rounded edges, the mixing container is cylindrical to avoid sharp corners, and the temperature sensor measures the temperature of the mixed solution in real time, which can ensure the activity of the bacterial agent and improve the application effect of the bacterial agent.

[0046] To facilitate understanding by those skilled in the art, the workflow of the microbial agent premixing device provided in this application is as follows: The liquid to be mixed is injected into the mixing container 1 through the liquid inlet 11 on the outer wall of the mixing container 1, and the required bacterial agent is added through the bacterial agent inlet 12. When the drive motor 3 enters the first state (powered operation), the control component 4 causes the output shaft of the drive motor 3 to drive the external magnetic rotor 51 to rotate in the first direction according to the target speed. At the same time, the encoder 41 of the adjustment component 4 rotates synchronously with the drive motor 3, continuously detects the speed of the drive motor 3 and transmits it to the regulator 42. The regulator 42 compares the actual speed with the preset value, calculates the difference, and adjusts the speed of the drive motor 3 to maintain a stable speed. When the drive motor 3 is in the second state (power off), by rotating the manual adjustment component 61, the overrunning clutch 63 is driven through the transmission belt 62, and the output shaft of the drive motor 3 drives the external magnetic rotor 51 to rotate in the second direction opposite to the first direction. When the drive motor 3 is in either the first or second state, the outer magnetic rotor 51 can drive the inner magnetic rotor 52 inside the mixing container 1 to rotate synchronously through magnetic coupling, thereby driving the stirring shaft 21 fixedly connected to the inner magnetic rotor 52 to rotate. The first stirring blade 241 (airfoil with downward tilt) on the stirring shaft 21 pushes the bacterial agent and the liquid to be mixed to move away from the inner magnetic rotor 52, while the second stirring blade 242 (airfoil with upward tilt) drives the bacterial agent and the liquid to be mixed to flow in opposite directions. Together with the baffle 25 on the inner wall of the mixing container 1, turbulence is formed to achieve uniform mixing of the bacterial agent and the liquid. After mixing is completed, the mixed solution is discharged through the liquid outlet 13.

[0047] The microbial agent premixing device provided in this application includes a mixing container, a stirring mechanism, a drive motor, and an adjustment component. The mixing container holds the microbial agent and the liquid to be mixed. The drive motor provides driving force to the stirring mechanism within the mixing container. The adjustment component detects and adjusts the speed of the drive motor. By adjusting the speed of the drive motor according to the different characteristics of the microbial agent, the stirring speed of the stirring mechanism is changed and kept stable, ensuring that different types of microbial agents are fully and evenly mixed with the liquid to be mixed. This improves the application effect of the microbial agent and solves the problem of uneven concentration of the microbial agent in the mixed solution caused by manual stirring, avoiding the impact of uneven concentration on the application effect of the microbial agent. Two layers of stirring blades create turbulent flow between the liquid to be mixed and the microbial agent mixture. The lengths of the first and second stirring blades can reach the inner wall of the mixing container. The baffle plate further improves the uniformity of the mixed solution by disturbing the regular flow formed by the first and second stirring blades. The first and second stirring blades and the baffle plate have rounded edges, the mixing container is cylindrical to avoid sharp corners, and the temperature sensor measures the temperature of the mixed solution in real time, which can ensure the activity of the bacterial agent and improve the application effect of the bacterial agent.
