Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, and in particular to an agronomic fertilizer application device. Background Technology

[0002] Agronomy, an important branch of agricultural science, primarily studies the cultivation, management, and optimization of crop planting techniques, aiming to improve crop yield and quality and ensure the sustainable development of agricultural production. In agronomic practice, fertilization, as a crucial step in enhancing soil fertility and promoting healthy crop growth, has a significant impact on plant growth outcomes due to its operational methods and efficiency. Traditional fertilization methods rely heavily on manual operation, which is not only labor-intensive but also difficult to control in terms of uniformity. This is especially true in teaching practice or scientific research experiments, where traditional methods are inefficient and inconsistent when dealing with a large number of small potted plants. Therefore, to meet the needs of modern agricultural teaching and experiments for efficient and precise fertilization, fertilization devices have emerged and occupy an important position in the field of agronomic equipment. As a core component in the fertilization process, its structural design and functional implementation have a decisive influence on the convenience, uniformity, and efficiency of fertilization.

[0003] An existing utility model patent, CN 222485348, discloses an agronomic fertilization device. By incorporating a mixing component and a fertilization component, it achieves preliminary mixing and quantitative irrigation of fertilizer, improving the convenience and consistency of fertilization to some extent, making it suitable for agronomic teaching practice. However, in actual use, this device still has technical defects: the mixing frame is located inside the mixing tank, and its up-and-down movement relies on manually pulling a rope to achieve the mixing operation. This method is not only time-consuming and labor-intensive, increasing the user's workload, but also has low mixing efficiency, making it difficult to ensure that the fertilizer is fully and evenly mixed, thus affecting the uniformity of subsequent fertilization and the consistency of crop absorption.

[0004] Therefore, to address the shortcomings of existing technologies, we urgently need an agronomic fertilization device to solve this problem. This new device should significantly improve the uniformity of fertilizer mixing and the precision of fertilization while reducing operational difficulty, better meeting the diverse fertilization needs of modern agronomic teaching, research, and small-scale planting scenarios, and providing strong support for the sustainable development of the agronomic field. Utility Model Content

[0005] The purpose of this invention is to provide an agronomic fertilization device that solves the problem in existing devices where the mixing frame is located inside the mixing tank, and its up-and-down movement relies on manually pulling a rope to achieve the mixing operation. This method is not only time-consuming and labor-intensive, increasing the user's workload, but also has low mixing efficiency, making it difficult to ensure that the fertilizer is fully and evenly mixed, thus affecting the uniformity of subsequent fertilization and the consistency of crop absorption.

[0006] To achieve the above objectives, this utility model provides an agronomic fertilization device, including a water storage tank and a mixing tank. The top of the water storage tank is connected to the bottom of the mixing tank. The bottom of the water storage tank is connected to a base by several support rods, and a potted plant is placed on the top of the base.

[0007] A drainage hole is provided at the center of the bottom of the mixing chamber. The interior of the water storage chamber is equipped with a sealing structure that matches the drainage hole. An adjusting screw is connected to the bottom of the sealing structure. One end of the adjusting screw passes through the bottom of the water storage chamber through a sealing screw sleeve. A water outlet pipe is provided on one side of the bottom of the water storage chamber.

[0008] The mixing chamber is connected to a top cover, and a round rod is rotatably connected to the bottom center of the top cover. A rotating shaft is rotatably connected to one side of the bottom. A stirring structure is connected to the bottom end of the rotating shaft. An upper ball chamber is connected to the bottom end of the round rod. A lower ball chamber is detachably connected to the bottom of the upper ball chamber. Several through slots are opened on the outer ring of both the upper and lower ball chambers. A drive assembly for synchronously driving the rotating shaft and the round rod is provided on the top of the top cover.

[0009] The sealing structure includes a conical plug, and the end of the adjusting screw is fixedly connected to the bottom of the conical plug.

[0010] The stirring structure includes several stirring rods, each of which is fixedly connected to the end of a rotating shaft.

[0011] The outlet pipe is equipped with a switch valve on one side, and the bottom end of the adjusting screw is fixedly connected to a handle, the outer ring of which has several anti-slip grooves.

[0012] The drive assembly includes a drive motor connected to the top of the top cover via a mounting bracket. The mounting bracket contains a drive gear disk, and a driven gear disk is connected to one side of the drive gear disk via a meshing connection. The output shaft of the drive motor is connected to the top of the drive gear disk, one end of the rotating shaft is connected to the bottom of the drive gear disk, and one end of the round rod is connected to the bottom of the driven gear disk.

[0013] The bottom of the upper ball chamber is connected to an external threaded ring, and the top of the lower ball chamber is connected to an internal threaded ring that is compatible with the external threaded ring.

[0014] This invention relates to an agronomic fertilization device. By incorporating a synchronous rotation system controlled by a drive assembly, including a rotating shaft, a stirring structure, a round rod, and a combination of upper and lower ball chambers, it effectively replaces the traditional method of manually pulling a rope for stirring. This significantly reduces the operator's workload and improves the automation level and ease of operation of the mixing process. Furthermore, because the stirring structure rotates synchronously with the upper and lower ball chambers, it respectively achieves water disturbance and fertilizer release functions, resulting in a more uniform distribution of fertilizer within the mixing chamber and a significant improvement in mixing efficiency. This solves the problems of uneven mixing and unstable operation in the original device, thus ensuring the uniformity and consistency of subsequent fertilization. This facilitates the accurate collection of experimental data and the effective presentation of comparative teaching results. Attached Figure Description

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0023] Example 1

[0024] Please see Figure 1-5 As shown, an agronomic fertilization device of this embodiment includes a water storage tank 2 and a mixing tank 3. The top of the water storage tank 2 is connected to the bottom of the mixing tank 3. The bottom of the water storage tank 2 is connected to a base 1 through several support rods 5. A potted plant 6 is set on the top of the base 1.

[0025] A drain hole 19 is provided at the center of the bottom of the mixing chamber 3. The interior of the water storage chamber 2 is equipped with a sealing structure that is compatible with the drain hole 19. An adjusting screw 8 is connected to the bottom of the sealing structure. One end of the adjusting screw 8 passes through the bottom of the water storage chamber 2 through a sealing screw sleeve. A water outlet pipe 9 is provided on one side of the bottom of the water storage chamber 2.

[0026] The top of the mixing chamber 3 is connected to a top cover. A round rod is rotatably connected to the bottom center of the top cover. A rotating shaft 12 is rotatably connected to one side of the bottom. A stirring structure is connected to the bottom end of the rotating shaft 12. An upper ball chamber 15 is connected to the bottom end of the round rod. A lower ball chamber 16 is detachably connected to the bottom of the upper ball chamber 15. Several through slots are opened on the outer ring of both the upper ball chamber 15 and the lower ball chamber 16. A drive assembly for synchronously driving the rotating shaft 12 and the round rod is provided on the top of the top cover.

[0027] Workflow: First, remove the top cover from the top of the mixing chamber 3 and inject an appropriate amount of clean water into it. Then, separate the lower ball chamber 16 from the upper ball chamber 15, place the desired solid or granular fertilizer into the lower ball chamber 16, and reconnect the lower ball chamber 16 to the bottom of the upper ball chamber 15, ensuring a tight connection. Next, reinstall the top cover onto the top of the mixing chamber 3 and activate the drive assembly on the top cover. This drive assembly synchronously rotates the rotating shaft 12 and the round rod. The bottom end of the rotating shaft 12 is connected to a stirring structure. As the rotating shaft 12 rotates, the stirring structure causes the water in the mixing chamber 3 to swirl. Simultaneously, the round rod drives the upper ball chamber 15 and the connected lower ball chamber 16 to rotate synchronously, allowing the fertilizer to pass through the lower ball chamber 16. Multiple channels on the outer ring of the upper ball chamber 15 gradually release and fully mix with the water flow, thereby significantly improving the mixing efficiency and uniformity of fertilizer and water. After mixing, the adjusting screw 8 is manually rotated, and the sealing structure connected to it moves downward, releasing the blockage of the drain hole 19 at the bottom center of the mixing chamber 3, allowing the uniformly mixed fertilizer solution to flow into the water storage chamber 2 below for temporary storage through the drain hole 19. After the water storage chamber 2 has finished storing water, the adjusting screw 8 is rotated in the opposite direction, causing the sealing structure to rise and reseal the drain hole 19 to prevent liquid leakage. Finally, the potted plant 6 to be fertilized is placed on the top of the base 1, and the water outlet pipe 9 is opened to realize the quantitative watering and fertilization operation of the potted plant 6. The whole process does not require frequent manual intervention, and the operation is simple and continuous.

[0028] Example 2

[0029] Please see Figure 1-5 As shown, an agronomic fertilization device of this embodiment includes a sealing structure comprising a conical plug 20. The end of an adjusting screw 8 is fixedly connected to the bottom of the conical plug 20. Specifically, through the cooperative arrangement of the conical plug 20, the drainage hole 19, and the adjusting screw 8, when the adjusting screw 8 is rotated to move the conical plug 20 up and down, precise opening and closing control of the drainage hole 19 at the bottom of the mixing chamber 3 can be achieved, resulting in a good sealing effect and ease of operation. This avoids leakage of liquid in the non-drainage state and improves the overall stability and safety of the device.

[0030] A switch valve is installed on one side of the water outlet pipe 9, and a handle is fixedly connected to the bottom end of the adjusting screw 8. Several anti-slip grooves are opened on the outer ring of the handle. Specifically, through the cooperation of the switch valve and the water outlet pipe 9, the flow rate of fertilizer solution can be precisely controlled during irrigation. Combined with the anti-slip groove design on the handle at the bottom of the adjusting screw 8, the operator has better grip stability when manually adjusting the sealing structure, which achieves the effects of easy control of fertilizer application, improved operation safety and human-machine interaction experience.

[0031] Example 3

[0032] Please see Figure 1-5 As shown in the figure, an agronomic fertilization device of this embodiment includes a stirring structure comprising a plurality of stirring rods 11, each of which is fixedly connected to the end of a rotating shaft 12. Specifically, through the cooperative arrangement of the plurality of stirring rods 11 and the rotating shaft 12, after the driving component drives the rotating shaft 12 to rotate, the stirring rods 11 rotate synchronously with it, forming an effective disturbance to the water flow inside the mixing chamber 3. This achieves the technical effect of enhancing the uniformity of fertilizer and water mixing and improving mixing efficiency, solving the problem of uneven mixing in the traditional manual rope stirring method, and improving the quality of fertilization.

[0033] The drive assembly includes a drive motor 13 connected to the top of the top cover via a mounting bracket 7. An active gear disk 10 is housed inside the mounting bracket 7. A driven gear disk 14 is connected to one side of the active gear disk 10 via a meshing mechanism. The output shaft of the drive motor 13 is connected to the top of the active gear disk 10. One end of the rotating shaft 12 is connected to the bottom of the active gear disk 10, and one end of the round rod is connected to the bottom of the driven gear disk 14. A protective cover 4 is connected to the top of the top cover. Specifically, through the coordinated arrangement of the drive motor 13, the active gear disk 10, the driven gear disk 14, the rotating shaft 12, and the round rod, synchronous driving of the stirring structure and the ball chamber system is achieved. After the drive motor 13 starts, the active gear disk 10 drives the rotating shaft 12 to rotate, while the driven gear disk 14 drives the round rod to rotate, thus achieving linkage control between stirring and ball chamber rotation. This improves mixing efficiency and achieves automated operation, effectively replacing the traditional manual stirring method.

[0034] The bottom of the upper ball chamber 15 is connected to an external threaded ring 17, and the top of the lower ball chamber 16 is connected to an internal threaded ring 18 that is compatible with the external threaded ring 17. Specifically, through the matching of the external threaded ring 17 and the internal threaded ring 18, the upper ball chamber 15 and the lower ball chamber 16 can be detachably connected by tightening. When it is necessary to replace or add different types of fertilizer, the lower ball chamber 16 can be quickly disassembled and replaced, which achieves the effects of easy maintenance, adapting to diversified fertilization needs, and improving operational flexibility, while ensuring a tight connection and preventing fertilizer leakage.

[0035] This utility model provides an agronomic fertilization device, including a water storage tank 2 and a mixing tank 3. The top of the water storage tank 2 is connected to the bottom of the mixing tank 3 to receive the uniformly mixed fertilizer solution discharged from the mixing tank 3. The bottom of the water storage tank 2 is connected to a base 1 through several support rods 5. The base 1 serves as the supporting foundation of the entire device, and a potted plant 6 is set on its top to facilitate direct watering of the potted plant during fertilization.

[0036] During use, firstly, remove the top cover from the top of the mixing chamber 3 and inject an appropriate amount of clean water into it; then separate the lower ball chamber 16 from the upper ball chamber 15, place the required solid or granular fertilizer into the lower ball chamber 16, and then reconnect it to the bottom of the upper ball chamber 15 through the threaded engagement between the external threaded ring 17 and the internal threaded ring 18, ensuring a tight and leak-free connection; then reinstall the top cover onto the top of the mixing chamber 3 and start the drive assembly mounted on the top cover. This drive assembly includes a drive motor 13 fixed to the top of the top cover via a mounting bracket 7. The mounting bracket 7 contains a drive gear disk 10 and a driven gear disk 14. The output shaft of the drive motor 13 is connected to the top of the drive gear disk 10, and rotates... One end of the shaft 12 is connected to the bottom of the drive gear disk 10, and one end of the round rod is connected to the bottom of the driven gear disk 14. When the drive motor 13 is running, the drive gear disk 10 drives the rotating shaft 12 to rotate, and drives the driven gear disk 14 to rotate synchronously through the meshing of the teeth, thereby driving the round rod and the upper ball chamber 15 and lower ball chamber 16 connected to it to rotate synchronously. At the same time, several stirring rods 11 in the stirring structure connected to the end of the rotating shaft 12 rotate together with the rotating shaft 12, forming a strong disturbance to the water flow inside the mixing chamber 3, thereby achieving efficient mixing. The fertilizer is gradually released through multiple through slots opened on the outer ring of the upper ball chamber 15 and lower ball chamber 16 and is fully mixed with the water flow, improving the mixing efficiency and uniformity.

[0037] After mixing, the operator manually rotates the adjusting screw 8 by holding the handle. The end of the adjusting screw 8 is fixedly connected to the bottom of the conical plug 20. As the adjusting screw 8 rotates, the conical plug 20 moves downward and disengages from the drain hole 19, allowing the mixed fertilizer solution to flow into the water storage tank 2 below for temporary storage through the drain hole 19. After the water storage tank 2 has filled with water, the adjusting screw 8 is rotated in the opposite direction, causing the conical plug 20 to rise and reseal the drain hole 19 to prevent liquid leakage. Finally, the potted plant 6 to be fertilized is placed on top of the base 1, and the switch valve installed on one side of the water outlet pipe 9 is opened to realize the quantitative watering and fertilization operation of the potted plant 6. The whole process does not require frequent manual intervention, and the operation is simple and continuous.
