[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0020] Please see Figures 1-5 This embodiment provides a drum screen for processing powdered fertilizer, including a base platform 1 and a cylinder 2. The cylinder 2 is arranged above the base platform 1. Multiple outer cylinders 11 are installed on the outer wall of the cylinder 2 along its circumferential direction. An inner rod 12 is installed on the inner end of the outer cylinder 11 by sliding fit. An inner position cylinder 13 is installed on the upper end face of the inner rod 12 and is arranged inside the cylinder 2. Multiple screen holes are opened on the inner end of the inner position cylinder 13. A driven gear 14 is installed on the outer wall of the cylinder 2 along its circumferential direction. A driving gear 15 is installed on the right side of the driven gear 14 through meshing rotation. A first motor 16 is installed at the bottom of wheel 15, and a control panel 26 is installed on the left end face of the base 1. The control panel 26 is electrically connected to the first motor 16. During operation, fertilizer is poured into the inner cylinder 13 and filtered through the sieve holes. Particles remain in the inner cylinder 13, while powdered fertilizer flows out. The first motor 16 starts, driving the drive gear 15 to rotate, which in turn drives the driven gear 14 to rotate, thereby causing the cylinder 2 to rotate. When the cylinder 2 rotates, the centrifugal force causes the inner cylinder 13 to shake up and down, thus improving the filtration effect of the fertilizer.

[0021] A triangular truncated pyramid 17 is installed at the bottom of the inner cylinder 2. Multiple discharge ports 18 are opened at the bottom of the cylinder 2 along its circumferential direction. A collection box 19 is arranged below the discharge ports 18. An end cap 21 is installed on the upper end face of the cylinder 2 by means of a thread. An inlet is installed on the upper end face of the end cap 21. During operation, fertilizer enters the inner cylinder 13 through the inlet. After the powdered fertilizer slides down through the triangular truncated pyramid 17 to the discharge port 18, it is collected and processed by the collection box 19.

[0022] The bottom of the cylinder 2 is provided with an annular groove, and multiple first sliders are installed in the annular groove by means of rotational engagement. A support column 22 is installed at the bottom of the first slider and the support column 22 is installed on the upper end face of the base 1. During operation, the structure of the first slider and the support column 22 is used to ensure the stability of the rotation of the cylinder 2.

[0023] A circular groove is provided on the upper surface of the base platform 1. A collection box 19 is arranged at the bottom of the circular groove. The bottom of the collection box 19 is screwed to the bottom of the base platform 1 by fixing bolts 23. An opening is provided at the front end of the circular groove. During operation, the collection box 19 is limited by fixing bolts 23 to prevent the collection box 19 from sliding back and forth, which would affect the collection effect of powdered fertilizer and thus cause material waste.

[0024] Multiple spring rods 24 are installed on the top of the end cap 21 along its circumferential direction. An annular plate 25 is installed at the bottom of the spring rods 24. During operation, when the inner cylinder 13 shakes up and down, the spring rods 24 drive the annular plate 25 to shake up and down, so that the annular plate 25 beats the inner cylinder 13, which further improves the up and down shaking effect of the inner cylinder 13 and can prevent fertilizer from clogging the screen holes of the inner cylinder 13.

[0025] In actual operation, fertilizer is poured into the inner cylinder 13 and filtered through the sieve holes. Particulate matter remains in the inner cylinder 13, while powdered fertilizer flows out. The first motor 16 starts, driving the drive gear 15 to rotate, which in turn drives the driven gear 14 to rotate, thereby causing the cylinder 2 to rotate. When the cylinder 2 rotates, the centrifugal force causes the inner cylinder 13 to shake up and down, thus improving the filtration effect of the fertilizer.
