[0025] The outer walls of the two adjacent rotating rods 6 are jointly sleeved with a first belt wheel belt 8, the outer wall of the rotating rod 6 is fixedly connected with a first belt wheel, the first belt wheel belt 8 is sleeved on the outer walls of the two first belt wheels, the plurality of rotating rods 6 are synchronously driven through the first belt wheel belt 8, and the rotating rod 6 penetrates through the partition plate 2 and is rotatably connected thereto.

[0026] The outer wall of the uppermost rotating rod 6 and the outer wall of the rotating rod 10 are jointly sleeved with a second belt wheel belt 9, the outer wall of the uppermost rotating rod 6 is fixedly connected with a driving belt wheel, the outer wall of the rotating rod 10 is fixedly connected with a driven belt wheel, and the second belt wheel belt 9 is sleeved on the outer walls of the driving belt wheel and the driven belt wheel.

[0027] The bottom of the rectangular frame 1 is equipped with four adjustment mechanisms. Each adjustment mechanism includes a fixed block that is fixedly connected to the outer wall of the rectangular frame 1. A T-shaped rod is threaded through the fixed block and connected to it. A support block is fixedly connected to the bottom of the T-shaped rod. The bottom of the support block is provided with anti-slip texture. By rotating the T-shaped rod, the support block is raised and lowered to adjust the device, making the device level. The device is installed stably and has a good screening effect.

[0028] In this invention, the worker pours granular organic fertilizer into the feed hopper 14 and starts the motor 5.

When the cam 7 rotates one revolution, its protruding part contacts the bottom of the filter screen 3, causing the filter screen 3 to swing counterclockwise. When the protruding part of the cam 7 no longer contacts the bottom of the filter screen 3, gravity causes the filter screen 3 to rotate clockwise, causing its bottom to contact the inner wall of the opening 4 and collide with it. The continuous rotation of the cam 7 causes the filter screen 3 to swing continuously, preventing clogging of the granular organic fertilizer on the filter screen 3 and ensuring smooth passage of the granular organic fertilizer material through the mesh during screening, resulting in excellent screening effect for granular organic fertilizer.

[0029] This invention solves the problems of existing technology where granular organic fertilizer materials are transferred into the screening equipment all at once, resulting in excessive material feeding that affects the screening effect. Furthermore, the filter screen becomes clogged during prolonged operation, affecting the subsequent screening effect of organic fertilizer particles.
