Description

Technical Field

[0001] This utility model relates to an air-filled fertilizer mixing device, belonging to the field of fertilizer mixing technology. Background Technology

[0002] With the development of modern agricultural technology, integrated water and fertilizer drip irrigation systems have become an important tool for improving agricultural production efficiency. This system achieves precise fertilization by dissolving fertilizer in irrigation water, making it particularly suitable for large-scale farmland operations. The uniformity of water and fertilizer mixing directly affects the fertilization effect and crop growth.

[0003] A fertigation device is used to thoroughly mix solid or liquid fertilizers with water to form a homogeneous solution. A typical fertigation device usually includes components such as a tank, a drive motor, a stirring shaft, and stirring blades, achieving water-fertilizer mixing through mechanical stirring. For example, existing literature (CN214228901U) discloses a fertigation integrated drip irrigation fertigation structure. This structure uses a motor-driven lead screw to rotate a stirring rod, while simultaneously using a telescopic airbag to generate bubbles to assist stirring. During stirring, the bubbles increase the contact between fertilizer and water, resulting in a more uniform mixture. However, in this structure, the bubbles are only released locally through the stirring rod, resulting in poor uniformity and incomplete fertilizer dissolution. Furthermore, the single stirring blade structure makes it difficult to create three-dimensional turbulence, affecting the water-fertilizer mixing speed. Utility Model Content

[0004] Based on the above, this utility model provides an air-filled fertilizer mixing device to overcome the shortcomings of the prior art.

[0005] The technical solution of this utility model is: a bubble-type fertilizer mixing device, comprising:

[0006] A stirring unit includes a tank, a drive mechanism, a stirring rod, and a stirring paddle. The drive mechanism is installed on the top of the tank, the top of the stirring rod is connected to the drive mechanism, and the stirring paddle is installed on the stirring rod.

[0007] The bubble unit includes an air pump, a rotary joint, an air pipe, and an annular aeration disc. The rotary joint is installed on the top of the stirring rod. The air pump is connected to the rotary joint through the air pipe. The stirring rod has an airflow channel inside and a first bubble hole connected to the airflow channel is opened on the stirring rod. The annular aeration disc is installed circumferentially inside the middle section of the tank. The annular aeration disc is connected to the air pipe through a branch pipe. Second bubble holes are evenly distributed on the annular aeration disc.

[0008] In one example, the lower end of the tank is conical, and the bottom of the tank is provided with support legs; the upper end of the tank is provided with a feeding pipe, the lower part of the tank is provided with a discharge pipe, and the discharge pipe is provided with a discharge valve.

[0009] In one example, the agitator comprises an upper agitator, a middle agitator, and a lower agitator, arranged sequentially from top to bottom on the agitator bar, with the lower agitator being V-shaped and the upper agitator being inverted V-shaped.

[0010] In one example, the drive mechanism includes a motor, a bracket, a drive gear, and a driven gear. The motor is mounted upside down on the top of the tank via the bracket. The drive gear is connected to the output shaft of the motor. The driven gear is fitted onto the upper part of the stirring rod. The drive gear meshes with the driven gear. The upper part of the stirring rod is mounted on the tank via a bearing.

[0011] In one example, the inner wall of the middle section of the tank is provided with U-shaped clips spaced circumferentially, and the annular aeration disc is fixed in the U-shaped clips.

[0012] The beneficial effects of this invention are as follows: The synergistic effect of the first bubble hole on the stirring rod and the second bubble hole on the annular aeration disc achieves a uniform distribution of bubbles in the axial and radial directions of the tank, eliminating mixing dead zones and significantly improving the uniformity of fertilizer-water mixing. Furthermore, the combination design of the V-shaped and inverted V-shaped stirring paddles creates an upward and downward convection vortex, enhancing the liquid turbulence effect and accelerating fertilizer dissolution.

The driven gear 24 is fitted on the upper part of the stirring rod 3, and the drive gear 23 meshes with the driven gear 24. The upper part of the stirring rod 3 is installed on the tank 1 via a bearing 16. The bearing 16 is a thrust bearing 16, a thrust ball bearing 16, and a thrust cylindrical roller bearing 16. Multiple stirring paddles 4 are installed on the stirring rod 3, so that the rotation of the motor 21 is transmitted to the stirring shaft through the drive gear 23 and the driven gear 24, and the stirring shaft drives the stirring paddles 4 to rotate.

[0020] The bubble unit includes an air pump 5, a rotary joint 6, an air pipe 7, and an annular aeration disc 8. The rotary joint 6 is installed on the top of the stirring rod 3. The air pump 5 is connected to the rotary joint 6 through the air pipe 7. An airflow channel is installed inside the stirring rod 3. Multiple first bubble holes 9 connected to the airflow channel are opened on the stirring rod 3. U-shaped clips 11 are installed circumferentially at intervals on the inner wall of the middle section of the tank 1. The annular aeration disc 8 is fixed in the U-shaped clips 11.
