[0003] Existing fertilizer dosage adjustment mechanisms include plug-in plates, which block the material passage to change the fertilizer conveying area and thus adjust the fertilizer dosage.

[0004] However, the use of the plate not only occupies a large space, which is not conducive to the integrated design of the fertilizer spreader, but also the fertilizer conveying area and the translational movement distance of the plate change in a stepwise manner, which is not effective in regulating the amount of fertilizer and can easily lead to too much or too little fertilizer.

[0007] The rotating shaft is rotatably mounted inside the fertilizer delivery chamber;

[0008] An adjusting member is installed on the rotating shaft and extends radially. The outer edge of the adjusting member contacts the inner wall of the fertilizer conveying chamber. When the rotating shaft drives the adjusting member to rotate, the adjusting member can drive the fertilizer to flow in the fertilizer conveying chamber, and the flow rate of the fertilizer is proportional to the rotation rate of the adjusting member, or change the flow area of ​​the fertilizer.

[0013] Furthermore, the circular plates have two spaced apart along the axial direction, and the arc-shaped plate is connected between the two circular plates.

[0014] Furthermore, the fertilizer delivery chamber has at least two symmetrically distributed chambers, each of which is provided with the rotating shaft and the adjusting component, and the housing has a clearance hole that extends vertically through the middle position.

[0015] Furthermore, the housing includes a detachably connected upper shell and a lower shell, which, when connected, form the fertilizer delivery chamber.

[0031] Specific implementation method one: Combining Figures 1 to 5 This embodiment describes a housing 1, a rotating shaft 5, and an adjusting component. The housing 1 has a fertilizer conveying chamber 2, which has an inlet 3 and an outlet 4. The inlet 3 is located on the top surface of the housing 1, and the outlet 4 is located on the bottom surface of the housing 1. The rotating shaft 5 is rotatably disposed inside the fertilizer conveying chamber. The adjusting component is mounted on the rotating shaft 5 and extends radially. The outer edge of the adjusting component contacts the inner wall surface of the fertilizer conveying chamber 2. When the rotating shaft 5 drives the adjusting component to rotate, the adjusting component can drive the fertilizer to flow in the fertilizer conveying chamber 2, and the flow rate of the fertilizer is proportional to the rotation rate of the adjusting component, or change the flow area of ​​the fertilizer.

[0032] In this embodiment of the fertilizer control mechanism, fertilizer enters from the inlet 3 and flows out from the outlet 4. The flow rate or flow area of ​​the fertilizer changes linearly with the rotation of the rotating shaft 5, making the fertilizer amount adjustment more precise. It can accurately adjust to the corresponding amount of fertilizer as needed. Moreover, the rotating shaft 5 and the adjusting components are integrated into the housing 1, which occupies less space and is more conducive to the integrated design of the fertilizer spreader.

[0033] Specific Implementation Method Two: Combining Figure 3This embodiment differs from specific embodiment one in that the adjusting component is a spiral blade 6. The inlet 3 and outlet 4 are spaced apart axially. The spiral blade 6 extends from the inlet 3 to the outlet 4. When the rotating shaft 5 drives the spiral blade 6 to rotate, the spiral blade 6 drives the fertilizer to flow from the inlet 3 to the outlet 4. At this time, the flow rate of the fertilizer is proportional to the rotation rate of the spiral blade 6. The rotating shaft 5 is connected to the drive motor 8 through the transmission assembly 7. The drive motor 8 drives the rotating shaft 5 to rotate. The fertilizer dosage is adjusted by changing the speed of the drive motor 8. This method is automatic adjustment, requiring no manual operation, and has a higher degree of automation. Other components and connections are the same as in specific embodiment one.

[0034] Specific implementation method three: Combining Figure 4 , Figure 5 This embodiment differs from specific embodiment two in that the transmission assembly 7 includes a meshing drive gear 9 and a driven gear 10. The drive gear 9 is mounted on the rotating shaft 11 of the drive motor 8, and the driven gear 10 is mounted on the rotating shaft 5. Specifically, the diameter of the drive gear 9 is larger than the diameter of the driven gear 10. When the drive motor 8 drives the drive gear 9 to rotate, the drive gear 9 drives the driven gear 10 to rotate, and the driven gear 10 drives the rotating shaft 5 to rotate. Due to the larger diameter of the drive gear 9, a speed-increasing transmission effect can be achieved, thereby reducing the speed requirement of the drive motor 8 and reducing manufacturing costs. Other components and connections are the same as in specific embodiment two.

[0035] Specific implementation method four: Combination Figure 7 , Figure 8 This embodiment differs from specific embodiment one in that the adjusting component includes a fixedly connected circular plate 12 and an arc-shaped plate 13. The vertical projections of the inlet 3 and outlet 4 coincide. The circular plate 12 is mounted on the rotating shaft 5, and the arc-shaped plate 13 is fitted against the inner wall of the fertilizer conveying chamber 2 and located between the inlet 3 and outlet 4. The circular plate 12 and the arc-shaped plate 13 can be connected by welding or are integrally formed. The inlet 3 and outlet 4 are located in the same position. The circular plate 12 serves as a connector, and the arc-shaped plate 13 is fitted against the inner wall of the fertilizer conveying chamber 2. This method allows for manual adjustment. The operator rotates the rotating shaft 5, which rotates the arc-shaped plate 13, causing it to block the inlet 3 or outlet 4. By changing the blocking area, the fertilizer flow area is adjusted. Other components and connections are the same as in specific embodiment one.

[0036] Specific Implementation Method Five: Combining Figure 7 , Figure 8This embodiment differs from Specific Embodiment Four in that it has two circular plates 12 spaced apart along the axial direction, with an arc-shaped plate 13 connecting the two circular plates 12. The two circular plates 12 are respectively supported at both ends of the arc-shaped plate 13. The arc-shaped plate 13 has more support points, making the installation more stable and less prone to breakage when impacted by fertilizer, thus improving its stability in use. Other components and connections are the same as in Specific Embodiment Four.

[0037] Specific Implementation Method Six: Combination Figure 1 , Figure 2 This embodiment differs from specific embodiment one in that it has at least two symmetrically distributed fertilizer conveying chambers 2. Each fertilizer conveying chamber 2 is equipped with a rotating shaft 5 and an adjusting component. The housing 1 has a vertically penetrating clearance hole 14 in the middle position, which is used for the passage of the stirring shaft. In this embodiment, there are two fertilizer conveying chambers 2. The symmetrically distributed fertilizer conveying chambers 2 can realize multi-point synchronous discharge. The adjusting component in each chamber independently or in conjunction controls the flow rate, avoiding the problem of local over-fertilization or local under-fertilization caused by material imbalance or channel blockage when conveying fertilizer in a single chamber. Other components and connections are the same as in specific embodiment one.

[0038] Specific implementation method seven: Combination Figures 1 to 8 This embodiment differs from specific embodiment one in that the housing 1 includes a detachably connected upper housing 15 and lower housing 16. The upper housing 15 and lower housing 16, when connected, form the fertilizer conveying chamber 2. The detachable structure breaks the closed constraint of the integrated housing 1, allowing for the installation, disassembly, and maintenance of internal components (rotating shaft 5, spiral blade 6, arc plate 13, bearings, etc.) without requiring complete disassembly of the equipment, significantly reducing operational difficulty. Other components and connections are the same as in any one of specific embodiments one through six.

[0039] Specific implementation method eight: Combination Figures 1 to 8 This embodiment differs from specific embodiment seven in that the upper shell 15 and the lower shell 16 are detachably connected by a round cover 17. The round cover 17, the upper shell 15, and the lower shell 16 together form the fertilizer conveying cavity 2. The round cover 17 can serve as the base for supporting the rotating shaft 5, making the whole assembly easier to disassemble. Other components and connections are the same as in specific embodiment seven.

[0040] Specific Implementation Method Nine: Combining Figures 1 to 8This embodiment differs from specific embodiment eight in that both ends of the upper shell 15 and the lower shell 16 are provided with semi-arc plates 18. The outer surface of the semi-arc plates 18 is provided with external threads, and the inner surface of the round cover 17 is provided with internal threads that mate with the external threads. Both ends of the rotating shaft 5 are rotatably connected to the round cover 17. During installation, the upper shell 15 and the lower shell 16 are first joined together, and then the round cover 17 is placed on the semi-arc plates 18 and rotated. Under the action of the threaded connection, the round cover 17 fixes the upper shell 15 and the lower shell 16 together. Other components and connections are the same as in specific embodiment eight.

[0041] Specific Implementation Method Ten: Combining Figures 1 to 8 This embodiment also provides a fertilizer dispenser employing the fertilizer dosage control mechanism described above, comprising a storage tank and a centrifugal winch disc. The storage tank is located above the fertilizer dosage control mechanism, with its outlet facing the feed inlet 3 of the fertilizer dosage control mechanism. The centrifugal winch disc is located below the fertilizer dosage control mechanism, with its inlet facing the discharge outlet 4 of the fertilizer dosage control mechanism. By employing a linear fertilizer dosage adjustment method, not only is fertilizer dosage control more precise, but the overall space occupied is also smaller, facilitating the integrated design of the fertilizer dispenser. Other components and connections are the same as in any of the specific embodiments one to nine.

[0042] The working principle of this implementation method is as follows:

[0043] The automatic fertilizer dosage adjustment mechanism uses a drive motor 8 to rotate a rotating shaft 5 via a rotating shaft 11, a drive gear 9, and a driven gear 10. This rotation drives the spiral blades 6 to rotate, which in turn transports the fertilizer. By changing the rotation of the drive motor 8, the flow rate of the fertilizer is changed accordingly, thus achieving the effect of fertilizer dosage adjustment.

[0044] The fertilizer dosage can be manually adjusted by manually rotating the shaft 5, which in turn rotates the arc plate 13. The arc plate 13 blocks the feed inlet 3 or the discharge outlet 4, thereby changing the flow area of ​​the fertilizer and achieving the effect of fertilizer dosage adjustment.

[0045] The scope of this utility model is not limited to the above-described embodiments; a combination of one or more specific embodiments can also achieve the purpose of this utility model.
