[0002] In the agricultural field, especially in fruit tree cultivation, the use of fertilizers is crucial. Granular fertilizers are a common way to fertilize apple trees. However, the screening technology of granular fertilizers faces some challenges. Traditional screening methods are often inefficient and cannot meet the fertilization needs of large-scale orchards. At the same time, the screening process is prone to problems such as fertilizer clogging the screen and insufficient screening accuracy, resulting in unsatisfactory fertilization results.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Figure 1-Figure 3 : Embodiment 1: A specific implementation of a loop-type granular fertilizer screening device is as follows: First, we constructed a screening device including an outer retaining cylinder 1 and a screening cylinder 3. The outer retaining cylinder 1 serves as a solid shell to support and protect the internal screening mechanism, and a discharge port is provided at its bottom so that the screened fertilizer particles can be discharged smoothly. Directly below the discharge port, we set a receiving box 5 to collect the screened fertilizer particles for subsequent collection and processing.

[0020] The screening cylinder 3 is the core part of the device. We adopt a combined design of a connecting section 31 and a screening section 32. At least one set of connecting sections 31 and screening sections 32 is provided, and they are connected in sequence to form an annular closed loop structure. This design not only improves the screening efficiency, but also makes the screening process more continuous and stable.

[0021] In order to facilitate the maintenance and replacement of the screening drum 3, a detachable structure is adopted between the connecting section 31 and the screening section 32. Specifically, a mounting plate 35 is fixedly installed on the screening section 32, and then the mounting plate 35 is installed on the connecting section 31 by bolts 34. In this way, when the screening section 32 needs to be maintained or replaced, we only need to loosen the bolts 34 to easily remove the screening section 32 from the connecting section 31.

[0022] At least one set of retaining protrusions 33 are installed on the inner wall of the screening section 32. These retaining protrusions 33 can effectively increase the contact area between the fertilizer particles and the screen, thereby improving the efficiency and accuracy of screening.

[0023] In order to drive the screening drum 3 to perform screening operations, a power assembly is provided. The power assembly includes a drive shaft 4, a drive motor 8 and a gear assembly. The drive motor 8 is fixedly mounted on the outer retaining cylinder 1, and the drive shaft 4 is rotatably connected to the outer retaining cylinder 1 and is fixedly connected to the screening drum 3. In this way, when the drive motor 8 is started, the screening drum 3 can be driven to rotate through the drive shaft 4.

[0024] The gear assembly is used to transmit the power of the driving motor 8 to the driving shaft 4. Specifically, the gear assembly includes a first gear 6 and a second gear 7. The output end of the driving motor 8 is connected to the second gear 7 through a coupling, and the first gear 6 is fixedly sleeved on the driving shaft 4. When the driving motor 8 is started, the second gear 7 will drive the first gear 6 to rotate, and then drive the screening drum 3 through the driving shaft 4 to perform screening operations.

[0025] In addition, in order to prevent the fertilizer particles from overflowing from the open end of the screening cylinder 3 during the screening process, a baffle 2 is also provided at the open end of the screening cylinder 3. Thus, when the screening cylinder 3 performs the screening operation, the baffle 2 can effectively prevent the fertilizer particles from overflowing from the open end of the screening cylinder 3, thereby ensuring the smooth progress of the screening.

[0026] In summary, by adopting the above specific implementation methods, we have constructed a loop-type granular fertilizer screening device that is efficient, stable, easy to maintain and replace.
