Description

Technical Field

[0001] This utility model relates to the field of microbial microbial compound fertilizer application, specifically to a microbial microbial compound fertilizer application device. Background Technology

[0002] In agricultural research and precision farming, especially in application trials of specialty fertilizers, precise, controllable fertilization operations capable of on-demand mixing of materials are crucial. These trials typically require the independent storage and metering of different fertilizer components in the field, followed by controlled mixing or diversion near the application point to study the effects of different ratios or application methods. Existing fertilization equipment, particularly for solid granular or powdery materials, often employs a single silo with a screw conveyor. In complex experimental scenarios involving specific transport paths, this structure struggles to simultaneously isolate and store multiple fertilizer components requiring independent control. Even with silo designs, the layout of the silo outlets and the transport paths in existing equipment are often relatively simple, making it difficult to flexibly support the complex connection requirements of multiple outlets and different downstream transport mechanisms. Furthermore, when experiments require the separate application and comparative analysis of specific components from different silos before fertilization, or controlled mixing, existing equipment often lacks effective control over separate and mixed application, necessitating multiple devices. Moreover, existing equipment faces challenges in achieving compact integration and reliable connection of multiple components. Utility Model Content

[0003] In view of the above problems, this application aims to propose a material distribution and mixing conveying network with a clear structure and controllable path by combining a hopper with specific partitions and multiple specific discharge ports with two-stage screw conveyor components with specific feed sources and discharge destinations, so as to solve the problems of spatial layout and functional realization of independent storage of multiple components and specific path conveying.

[0004] To achieve the above objectives, this application provides a microbial microbial compound fertilizer application device, characterized in that it includes a frame, a hopper, a first spiral conveying assembly, a second spiral conveying assembly, and a valve assembly: the hopper is connected to the frame, and a partition is provided in the middle to divide the hopper into a left hopper and a right hopper; the bottom of the left hopper has a left rear discharge port, and the bottom of the right hopper has a right front discharge port and a right rear discharge port; the first spiral conveying assembly includes a first housing and a first spiral shaft, the first housing is mounted on the frame, and the top of the first housing has a first inlet and a second inlet. The first feed inlet is connected to the front right discharge port of the hopper, and the second feed inlet is connected to the rear right discharge port of the hopper. The bottom of the first housing has discharge ports one and two. The first screw shaft is rotatably connected inside the first housing. The second screw conveyor assembly includes a second housing and a second screw shaft. The second housing is mounted on a frame. The top of the second housing has feed ports three and four. Feed port three is connected to discharge port one of the first housing, and feed port four is connected to the rear left discharge port of the hopper. The bottom of the second housing has discharge port three, and the second screw shaft is rotatably connected inside the second housing. The valve assembly includes a first valve, a second valve, a third valve, and a fourth valve. The first valve is installed inside feed port one, the second valve is installed inside feed port two, the third valve is installed inside discharge port one, and the fourth valve is installed inside discharge port two.

[0005] The above technical solution divides the hopper into a left hopper and a right hopper by a partition in the middle of the hopper, realizing the physical isolation and storage of different fertilizer components; the right front discharge port and right rear discharge port at the bottom of the right hopper can discharge the fertilizer stored therein independently, and the left rear discharge port at the bottom of the left hopper can discharge the fertilizer stored therein. The first spiral conveyor assembly receives fertilizer from the right front outlet through inlet one at its top and fertilizer from the right rear outlet through inlet two. Utilizing the forward and reverse rotation of the first spiral shaft and the opening and closing of the first, second, third, and fourth valves, the fertilizer is conveyed to either outlet one or outlet two at the bottom for flow direction control. Specifically, when fertilizing separately, the first valve (inlet one) and the third valve (outlet one) are closed, while the second valve (inlet two) and the fourth valve (outlet two) are opened. Material flows directly from the second inlet to the second outlet, achieving direct discharge from the right hopper, independent of the left hopper, allowing for simultaneous fertilization. Conversely, when fertilizing in a different location, material flows from the first inlet to the first outlet, entering the second housing and mixing with the material in the left hopper for fertilization. (Refer to...) Figures 8 to 11 The second spiral conveyor assembly receives fertilizer from the first spiral conveyor assembly's outlet one through its top inlet three, and fertilizer from the left rear outlet of the left hopper through its inlet four. The rotation of the second spiral shaft mixes and conveys the two types of fertilizer within the second housing, finally discharging them through the bottom outlet three. This embodiment achieves independent storage of multi-component fertilizers and allows for separate and mixed application via specific path changes, meeting the needs of simultaneous comparative and mixed application of different fertilizers in experiments.

[0006] In some embodiments, the first valve, the second valve, the third valve, and the fourth valve are electrically controlled switching valves.

[0007] In some embodiments, the first spiral conveying assembly further includes a first motor mounted on a frame and drivenly connected to a first spiral shaft; the second spiral conveying assembly further includes a second motor mounted on a frame and drivenly connected to a second spiral shaft.

[0008] In some embodiments, the experimental microbial compound fertilizer application equipment also includes a walking component, which includes walking wheels that are rotatably connected to the frame.

[0009] In some embodiments, the walking assembly further includes a drive motor mounted on the frame and connected to the walking wheel drive.

[0010] In some embodiments, the frame is provided with handrails.

[0011] In some embodiments, a positioning plate is provided on the frame. The positioning plate is located at the bottom of the first spiral conveying assembly and the second spiral conveying assembly. The positioning plate is provided with two or more positioning holes. The first housing outlet 2 and the second housing outlet 3 are respectively connected to the positioning hole pipeline.

[0012] In some embodiments, the experimental microbial compound fertilizer application equipment also includes a soil covering component, which is a soil covering disc mounted on the frame and located at the rear end of the bottom of the frame.

[0013] In some embodiments, the experimental microbial compound fertilizer application equipment for trace elements further includes a control component, which includes a controller, a driver, and a power source. The controller, driver, and power source are mounted on a frame. The controller is communicatively connected to the driver, the power source is electrically connected to the driver, and the driver is drively connected to the first spiral conveying component and the second spiral conveying component, respectively.

[0014] Unlike existing technologies, this utility model provides a microbial compound fertilizer application device for trace elements. The hopper is divided into a left and right feed bin by a partition in the middle, achieving physical isolation and storage of different fertilizer components. The right front and right rear discharge ports at the bottom of the right feed bin are connected to the inlet one and inlet two of the first spiral conveyor assembly's first housing via a first valve and a second valve, respectively. The left rear discharge port at the bottom of the left feed bin is directly connected to the inlet four of the second spiral conveyor assembly's second housing. The first spiral conveyor assembly controls the opening and closing of discharge ports one and two via a third valve and a fourth valve, respectively. Discharge port one is connected to the inlet three of the second housing, enabling mixed conveying of some material from the right and left feed bins. A first motor and a second motor drive the first and second spiral shafts to rotate, achieving precise material delivery. The drive motor of the walking assembly rotates the walking wheels, allowing the device to move in the field. The positioning holes on the positioning plate connect to the discharge ports two and three of the first and second housings, allowing for flexible adjustment of the fertilization position. The soil-covering disc completes the fertilizer covering at the rear bottom of the vehicle frame. The control unit coordinates the operation of each component through the controller and drive, realizing the fully automated operation of independent storage, precise delivery, controllable mixing, positioning fertilization and automatic soil covering of multi-component fertilizers.

[0015] In summary, the experimental microbial compound fertilizer application equipment for trace elements provided by this utility model, through a hopper with specific partitions and multiple specific discharge ports, combined with two-stage spiral conveying components with specific feed sources and discharge destinations, constructs a material conveying network with a clear structure and controllable path, solving the problems of spatial layout and functional realization of independent storage of multiple components and specific path conveying.

[0027] Please see Figures 1 to 11 This embodiment provides a microbial microorganism compound fertilizer application device, characterized by comprising a frame 10, a hopper 20, a first spiral conveying assembly 30, a second spiral conveying assembly 40, and a valve assembly: the hopper 20 is connected to the frame 10, and a partition is provided in the middle to divide the hopper 20 into a left material box 21 and a right material box 22. The bottom of the left material box 21 is provided with a left rear discharge port 2101, and the bottom of the right material box 22 is provided with a right front discharge port 2201 and a right rear discharge port 2202; the first spiral conveying assembly 30 includes a first housing 33 and a first spiral shaft 34. The first housing 33 is mounted on the frame 10, and the top of the first housing 33 is provided with a first inlet 31 and a second inlet 32, which are connected to the first spiral shaft 40. The material box is connected to the right front discharge port 2201, and the material inlet 22 is connected to the right rear discharge port 2202 of the material box.

The top of the second housing 41 is provided with discharge port 3 43 and discharge port 44. Discharge port 3 43 is connected to discharge port 1 35 of the first housing 33. Discharge port 44 is connected to the left rear discharge port 2101 of the material box. The bottom of the second housing 41 is provided with discharge port 3 45. The second spiral shaft 42 is rotatably connected inside the second housing 41. The valve assembly includes a first valve, a second valve, a third valve, and a fourth valve. The first valve is installed in the feed inlet 31, the second valve is installed in the feed inlet 32, the third valve is installed in the discharge outlet 35, and the fourth valve is installed in the discharge outlet 36.

[0028] In this embodiment, the frame 10 refers to the basic frame part used to support and bear the overall structure of the equipment. The hopper 20 refers to the container fixedly connected to the frame 10 for holding the fertilizer to be applied. A partition is provided in the middle of the hopper 20. The partition is a plate-like structure vertically installed inside the hopper 20, which is used to divide the inner cavity of the hopper 20 into two independent spaces, namely the left hopper 21 and the right hopper 22, so as to achieve physical isolation and storage of different fertilizer components. A left rear discharge port 2101 is provided at the bottom of the left hopper 21. The left rear discharge port 2101 is an opening located at the rear bottom of the left hopper 21, used to discharge the fertilizer stored in the left hopper 21. The bottom area of ​​the right material box 22 is provided with a right front discharge port 2201 and a right rear discharge port 2202. The right front discharge port 2201 is an opening located at the front of the bottom of the right material box 22, and the right rear discharge port 2202 is an opening located at the rear of the bottom of the right material box 22. The two are used to discharge the fertilizer stored in the right material box 22.

[0029] The first spiral conveyor assembly 30 is a key mechanism for receiving and conveying fertilizer from the right hopper 22, and it includes a first housing 33 and a first spiral shaft 34. The first housing 33 is a closed structure with specific internal channels, fixedly mounted on the frame 10. The top of the first housing 33 has an inlet 31 and an inlet 32. Inlet 31 receives fertilizer discharged from the right front outlet 2201 of the hopper 20, and inlet 32 ​​receives fertilizer discharged from the right rear outlet 2202 of the hopper 20. The bottom of the first housing 33 has an outlet 35 and an outlet 36 for discharging the conveyed fertilizer. The first spiral shaft 34 is a spiral shaft rotatably mounted within the first housing 33; its rotation propels the fertilizer axially within the housing, thus conveying the material.

[0030] The second screw conveyor assembly 40 is a key mechanism for receiving and conveying fertilizer from the first screw conveyor assembly 30 and the left hopper 21. It includes a second housing 41 and a second screw shaft 42. The second housing 41 is another enclosed structure fixedly mounted on the frame 10. The top of the second housing 41 has a third inlet 43 and a fourth inlet 44. The third inlet 43 is for receiving fertilizer discharged from the first housing 33's outlet 35, and the fourth inlet 44 is for receiving fertilizer discharged from the left rear outlet 2101 of the hopper 20. The bottom of the second housing 41 has an outlet 45 for discharging the fertilizer conveyed thereto. The second screw shaft 42 is a helical shaft rotatably mounted inside the second housing 41, and its rotation is used to propel the fertilizer within the housing. The core of the material flow is that the first spiral conveyor assembly 30 simultaneously receives materials from the two discharge ports of the right hopper 22 and can be diverted through the two discharge ports at its bottom; while the second spiral conveyor assembly 40 simultaneously receives part of the material from the first spiral conveyor assembly 30 and the material from the left hopper 21, conveys it in the second housing 41 and finally discharges it from the discharge port 45, thus realizing material conveying and potential mixing along a specific path.

[0031] A valve assembly refers to a system composed of multiple valves used to control the flow direction, flow rate, or pressure of fluid in a pipeline. In this embodiment, the valve assembly includes a first valve, a second valve, a third valve, and a fourth valve, which are respectively installed in inlet 31, inlet 32, outlet 35, and outlet 36. The valves can be ball valves, gate valves, or butterfly valves, etc., and the specific selection depends on the fluid properties and working environment requirements. The first and second valves control the fluid input at inlet 31 and inlet 32, achieving fluid flow control or flow regulation by adjusting the valve's opening and closing status or opening degree. The third and fourth valves control the fluid output at outlet 35 and outlet 36, ensuring that the fluid is discharged along a preset path. The valves are typically made of stainless steel, cast iron, or copper alloy to adapt to the corrosiveness and pressure resistance requirements of different media. The coordinated operation of the valve assembly enables precise fluid control, meeting the management needs of multi-channel input and output in the process flow.

[0032] In this embodiment, the hopper 20 is divided into a left hopper 21 and a right hopper 22 by a partition in the middle of the hopper 20, so as to achieve physical isolation and storage of different fertilizer components; the right front discharge port 2201 and the right rear discharge port 2202 at the bottom of the right hopper 22 can discharge the fertilizer stored therein independently, and the left rear discharge port 2101 at the bottom of the left hopper 21 can discharge the fertilizer stored therein. The first spiral conveyor assembly 30 receives fertilizer from the right front outlet 2201 through its top inlet 31 and fertilizer from the right rear outlet 2202 through its inlet 32. It then uses the forward and reverse rotation of the first spiral shaft 34 and the opening and closing control of the first, second, third, and fourth valves to convey the fertilizer to the bottom outlet 35 or outlet 36 for flow direction control. Specifically, when fertilizing separately, the first valve (inlet 31) and the third valve (outlet 35) are closed, while the second valve (inlet 32) and the fourth valve (outlet 36) are opened. The material flows directly from the second inlet to the second outlet, achieving direct discharge of the material in the right hopper, independent of the left hopper, allowing for simultaneous fertilization. Conversely, when fertilizing separately, the material flows from the first inlet to the first outlet, entering the second housing 41 and mixing with the material in the left hopper for fertilization. The second spiral conveyor assembly 40 receives fertilizer from the first spiral conveyor assembly 30's outlet 35 via its top inlet 3 43 and fertilizer from the left rear outlet 2101 of the left hopper 21 via its inlet 44. The rotation of the second spiral shaft 42 mixes and conveys the two types of fertilizer within the second housing 41, finally discharging them through the bottom outlet 3 45. This embodiment achieves independent storage of multi-component fertilizers and allows for separate and mixed application via specific path changes, meeting the needs of simultaneous comparative and mixed application of different fertilizers in experiments.

[0033] Please see Figures 1 to 11 In some embodiments, the first valve, the second valve, the third valve, and the fourth valve are electrically controlled switching valves.

[0034] In this embodiment, an electrically controlled on / off valve refers to a fluid control element that is controlled to open and close by an electrical signal. Its core function is to realize the opening and closing of the pipeline medium or the switching of the flow direction. This type of valve can be electromagnetically driven or motor-driven. The electromagnetic valve directly drives the valve core to move by the magnetic force generated by the energization of the coil, while the electric valve completes the opening and closing of the valve by a motor driving a gear mechanism.

[0035] This embodiment achieves remote and precise control of inlet 1 (31), inlet 2 (32), inlet 3 (43), and inlet 4 (44) by configuring the first, second, third, and fourth valves as electrically controlled switching valves. The first valve of the electrically controlled switching valve can quickly adjust the fertilizer flow from the right front outlet 2201 of the hopper 20 to the first housing 33; the second valve independently controls the fertilizer delivery from the right rear outlet 2202 of the hopper 20 to the first housing 33; the third valve precisely manages the fertilizer flow from outlet 35 of the first housing 33 to the second housing 41; and the fourth valve intelligently regulates the fertilizer input from the left rear outlet 2101 of the hopper 20 to the second housing 41. This embodiment significantly improves the response speed and ease of operation of the valve assembly, making the delivery process of multi-component fertilizers more intelligent and precisely controllable.

[0036] Please see Figures 1 to 11 In some embodiments, the first spiral conveying assembly 30 further includes a first motor 37, which is mounted on the frame 10 and is drivenly connected to the first spiral shaft 34; the second spiral conveying assembly 40 further includes a second motor, which is mounted on the frame 10 and is drivenly connected to the second spiral shaft 42.

[0037] This embodiment provides supplementary description of the drive mechanism of the screw conveyor assembly. The first motor 37 is a power unit fixedly mounted on the frame 10, connected to the first screw shaft 34 via a transmission mechanism, and provides power for the rotational movement of the first screw shaft 34. The first screw shaft 34 is a screw-shaped conveying component rotatably mounted within the first housing 33, rotating under the drive of the first motor 37, thereby pushing fertilizer axially within the first housing 33. The second motor is also a power unit fixedly mounted on the frame 10, connected to the second screw shaft 42 via a transmission mechanism, and provides power for the rotation of the second screw shaft 42. The second screw shaft 42 is a screw-shaped conveying component rotatably mounted within the second housing 41, rotating under the drive of the second motor to convey fertilizer within the second housing 41. Both the first motor 37 and the second motor adopt a standard electric motor structure, and their power and speed parameters are matched according to the conveying requirements. The transmission connection between the motor and the screw shaft can be a direct connection using a coupling, or power can be transmitted through intermediate transmission mechanisms such as belts or chains. This split-type motor drive design allows the first spiral conveying assembly 30 and the second spiral conveying assembly 40 to operate independently, flexibly controlling the start / stop and conveying speed of each conveying assembly according to actual fertilization needs. The first motor 37 drives the first spiral shaft 34 to convey and divert fertilizer from the right hopper 22, while the second motor drives the second spiral shaft 42 to complete the mixed conveying of fertilizer from the left hopper 21 and part of the fertilizer from the right hopper 22. The two work together to ensure that the multi-component fertilizer is accurately conveyed along the predetermined path.

[0038] This embodiment achieves independent drive control of the screw conveyor assembly by adding a first motor 37 and a second motor. The first motor 37 drives the first screw shaft 34 to rotate via a transmission connection, enabling the first housing 33 to independently complete the conveying and diversion of fertilizer from the right hopper 22. The second motor drives the second screw shaft 42 to rotate via a transmission connection, enabling the second housing 41 to independently complete the mixing and conveying of fertilizer from the left hopper 21 and part of the fertilizer from the right hopper 22. The split-type motor drive design adopted in this embodiment allows the operation of the first screw conveyor assembly 30 and the second screw conveyor assembly 40 to be completely independently controlled. It can flexibly adjust the start and stop status of each conveyor assembly according to actual fertilization needs, and can precisely control the conveying speed and mixing ratio of different fertilizer components by adjusting the motor speed, thereby ensuring that multi-component fertilizers can be accurately conveyed and controlled for mixing according to experimental requirements.

[0039] Please see Figures 1 to 11 In some embodiments, the experimental microbial compound fertilizer application equipment also includes a walking component 60, which includes walking wheels 61 that are rotatably connected to the frame 10.

[0040] This embodiment provides supplementary explanation of the moving mechanism of the fertilizer application equipment. The walking assembly 60 refers to the functional module used to realize the overall movement of the equipment, and its core component is the walking wheel 61. The walking wheel 61 is a circular wheel-shaped component that is rotatably connected to the frame 10 via bearings or other rotating mechanisms, used to support the weight of the equipment and enable the equipment to roll on the ground. The rotatable connection between the walking wheel 61 and the frame 10 refers to the relative motion relationship achieved through mechanical structures such as axles and bearings, allowing the walking wheel 61 to rotate freely around a fixed axis.

[0041] In this embodiment, the traveling wheels 61 form a stable and reliable mechanical connection with the frame 10 via a rotatable connection, ensuring both the load-bearing capacity of the equipment during movement and maintaining the flexibility of the traveling wheels 61's rotation. The traveling wheels 61 enable the entire fertilization equipment to move smoothly in the field, providing a stable foundation for the movement of core working components such as the hopper 20, the first spiral conveyor assembly 30, and the second spiral conveyor assembly 40. This embodiment effectively solves the problem of inconvenient movement of traditional fertilization equipment, allowing the equipment to flexibly adjust its working position according to experimental needs, while ensuring the overall stability of the equipment during fertilization operations, creating favorable conditions for the precise application of microbial compound fertilizer containing trace elements.

[0042] Please see Figures 1 to 11 In some embodiments, the walking assembly 60 further includes a drive motor mounted on the frame 10 and connected to the walking wheel 61 in a transmission manner.

[0043] This embodiment further optimizes the functionality of the walking assembly 60 by adding a drive motor. The drive motor is fixedly mounted on the frame 10 and forms a power connection with the walking wheels 61 through a transmission mechanism, providing active driving force to the walking wheels 61.

[0044] This embodiment enables the fertilization equipment to move autonomously in the field without manual propulsion. The transmission connection between the drive motor and the walking wheels 61 ensures reliable power transmission, and the walking speed can be adjusted according to actual operational needs. This improvement significantly enhances the automation level and operational efficiency of the equipment, allowing operators to focus more on precise control of the fertilization process while reducing labor intensity. It provides a more convenient and efficient mobile solution for the application of experimental microbial compound fertilizer containing trace elements.

[0045] Please see Figures 1 to 11 In some embodiments, the frame 10 is provided with a handrail 12.

[0046] This embodiment provides operators with a direct handhold and leverage point by installing a handle 12 on the frame 10. The handle 12 is a horizontal or arc-shaped rod structure fixed at a specific position on the frame 10, with its height and angle conforming to ergonomic design. By gripping the handle 12, operators can apply pushing or pulling forces to the equipment, thereby controlling the direction and speed of the fertilization equipment in the field with less effort. This embodiment significantly improves the convenience of equipment movement and operation, reduces the labor intensity of operators, and enhances the stability control during movement, making the overall operation of fertilization more comfortable and efficient.

[0047] Please see Figures 1 to 11 In some embodiments, the frame 10 is provided with a positioning plate 11, which is located at the bottom of the first spiral conveying assembly 30 and the second spiral conveying assembly 40. The positioning plate 11 is provided with two or more positioning holes 1101, and the discharge port 36 of the first housing 33 and the discharge port 45 of the second housing 41 are respectively connected to the positioning holes 1101.

[0048] This embodiment supplements the output positioning structure of the fertilizer application equipment. The positioning plate 11 is a rigid plate fixedly installed on the frame 10, located at the bottom of the first spiral conveyor assembly 30 and the second spiral conveyor assembly 40, used to provide a fixing and guiding reference for the discharge port. The positioning plate 11 has two or more positioning holes 1101, which are circular or rectangular through holes distributed in a specific layout on the surface of the positioning plate 11, used to connect the conveying pipeline and determine the final discharge position of the fertilizer. Specifically, the connection relationship is as follows: the second discharge port 36 of the first housing 33 is connected to one of the positioning holes 1101 on the positioning plate 11 via a pipe; similarly, the third discharge port 45 of the second housing 41 is connected to another positioning hole 1101 via a pipe. The pipeline connection refers to using a flexible or rigid pipe to physically connect the discharge port to the positioning hole 1101, ensuring that the fertilizer is guided from the discharge port to the designated area through the positioning hole 1101. The positioning plate 11 is typically made of metal or high-strength engineering plastic, and its thickness and dimensions are designed according to load-bearing requirements. The distribution of multiple positioning holes 1101 can be flexibly arranged according to the planting row spacing of the experimental field. By selecting different positioning holes 1101 to connect the pipeline, the fertilizer output position can be precisely adjusted.

[0049] This embodiment significantly improves the accuracy and adaptability of fertilization location by setting a positioning plate 11. The positioning plate 11 is fixed to the frame 10 and located at the bottom of the first spiral conveyor assembly 30 and the second spiral conveyor assembly 40. Multiple positioning holes 1101 distributed on the plate form pipeline connections with the second outlet 36 of the first housing 33 and the third outlet 45 of the second housing 41, respectively. By selecting different positioning holes 1101 to connect the pipelines, this embodiment allows the fertilizer output from the second outlet 36 of the first housing 33 and the third outlet 45 of the second housing 41 to have their final discharge position adjusted according to experimental requirements. The spatial layout of the positioning holes 1101 provides a flexible flow guide reference, so that the fertilizer output path is no longer limited to a fixed outlet position, achieving precise positioning and rapid adjustment of the fertilization point in multi-row spacing experimental scenarios.

[0050] Please see Figures 1 to 11 In some embodiments, the experimental microbial compound fertilizer application equipment also includes a soil covering component 70, which is a soil covering disc mounted on the frame 10 and located at the bottom rear end of the frame 10.

[0051] This embodiment supplements the functional component for soil covering after fertilization. The soil covering component 70 refers to a mechanical structure used for soil covering operations after fertilizer discharge; in this embodiment, it specifically takes the form of a soil covering disc. The soil covering disc is a disc-shaped tool installed at the rear bottom of the frame 10, typically made of metal, with its surface at a certain angle to the direction of travel. The soil covering disc is rigidly connected to the frame 10 via a bracket or shaft mechanism, and its installation position is located at the rear bottom of the frame 10, i.e., below and behind the equipment in the direction of travel. This positioning ensures that when the equipment moves forward to fertilize, the soil covering disc can operate immediately behind the fertilizer discharge point.

[0052] This embodiment improves the fertilization process by adding a soil covering component 70. The soil covering component 70 is specifically in the form of a soil covering disc, which is fixedly installed at the rear end of the bottom of the frame 10. When the equipment moves forward to fertilize, the soil covering disc follows the fertilizer discharge points of the second discharge port 36 of the first housing 33 and the third discharge port 45 of the second housing 41. The soil covering disc, with its disc-shaped structure, cuts into the soil, turning over the soil on both sides and covering the surface of the discharged fertilizer during its movement. This embodiment replaces the traditional manual burial operation in the mechanical soil covering process, ensuring timely contact between the micronutrient microbial compound fertilizer and the soil, effectively reducing fertilizer efficiency loss, and significantly improving the standardization and continuous operation efficiency of the experimental fertilization operation.

[0053] Please see Figures 1 to 11 In some embodiments, the experimental microbial compound fertilizer application equipment also includes a control component 80, which includes a controller, a driver, and a power source. The controller, driver, and power source are mounted on the frame 10. The controller is communicatively connected to the driver, the power source is electrically connected to the driver, and the driver is drively connected to the first spiral conveying component 30 and the second spiral conveying component 40, respectively.

[0054] This embodiment supplements the central control system of the fertilization equipment. The control component 80 refers to the core module integrated on the frame 10 for coordinating equipment operation, including a controller, a driver, and a power source. The controller is an electronic processing unit fixedly installed on the frame 10, used to receive operating commands and generate control signals. The driver is a power amplifier device that establishes a communication connection with the controller via a cable, used to convert control signals into power commands to drive the actuators. The power source is a device that provides electrical energy to the entire system, electrically connected to the driver via a cable to supply energy. The driver forms a transmission connection with the first spiral conveyor assembly 30 and the second spiral conveyor assembly 40 respectively through a mechanical transmission mechanism. Specifically, the output end of the driver transmits power to the first motor 37 of the first spiral conveyor assembly 30 through a coupling or gear set, controlling the speed and direction of the first spiral shaft 34; simultaneously, it transmits power to the second motor of the second spiral conveyor assembly 40 through an independent channel, controlling the operating state of the second spiral shaft 42.

[0055] This embodiment achieves precise automated control of fertilization operations by adding a control component 80. The controller sends control commands to the driver via a communication connection; the driver converts the commands into power output and drives the first spiral shaft 34 of the first spiral conveyor assembly 30 and the second spiral shaft 42 of the second spiral conveyor assembly 40 via a transmission connection; the power source continuously provides electrical energy to the driver via an electrical connection. This embodiment enables the independent and controlled operation of the first spiral conveyor assembly 30 in conveying and diverting fertilizer to the right hopper 22 and the second spiral conveyor assembly 40 in conveying mixed fertilizer, achieving precise coordination of the start / stop, speed, and ratio of multi-component fertilizer conveying, significantly improving the controllability and operational accuracy of the fertilization process.

[0056] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: The present invention provides a micronutrient microbial compound fertilizer application device. The hopper 20 is divided into a left hopper 21 and a right hopper 22 by a partition in the middle, achieving physical isolation and storage of different fertilizer components. The right front discharge port 2201 and right rear discharge port 2202 at the bottom of the right hopper 22 are controlled by a first valve and a second valve, respectively, to connect to the feed inlet 31 and feed inlet 32 ​​of the first housing 33 of the first screw conveyor assembly 30. The left rear discharge port 2101 at the bottom of the left hopper 21 is directly connected to the feed inlet 44 of the second housing 41 of the second screw conveyor assembly 40. The first screw conveyor assembly 30 controls the opening and closing of the discharge port 35 and discharge port 36 by a third valve and a fourth valve, respectively. The discharge port 35 is connected to the feed inlet 43 of the second housing 41, realizing the mixed conveying of some material from the right hopper 22 and the left hopper 21. The first motor 37 and the second motor drive the first spiral shaft 34 and the second spiral shaft 42 to rotate, respectively, to achieve precise material delivery. The drive motor of the walking assembly 60 drives the walking wheels 61 to rotate, enabling the equipment to move in the field. The positioning hole 1101 on the positioning plate 11 is connected to the pipeline of the second discharge port 36 of the first housing 33 and the third discharge port 45 of the second housing 41, allowing for flexible adjustment of the fertilization position. The soil covering disc completes the fertilizer covering at the rear bottom of the frame 10. The control assembly 80 coordinates the operation of each component through the controller and the drive, realizing the fully automated operation of independent storage, precise delivery, controllable mixing, positioning fertilization, and automatic soil covering of multi-component fertilizers.

[0057] In summary, the experimental microbial compound fertilizer application equipment for trace elements provided by this utility model, through a hopper with specific partitions and multiple specific discharge ports, combined with two-stage spiral conveying components with specific feed sources and discharge destinations, constructs a material conveying network with a clear structure and controllable path, solving the problems of spatial layout and functional realization of independent storage of multiple components and specific path conveying.
