When in use, the fertilizer to be screened is poured into the feed hopper 11 and falls into the inside of the screen frame 2, and then the reciprocating mechanism 3 is started to drive the screen frame 2 to move back and forth, so that the fertilizer with larger particle size can be intercepted and the fertilizer with smaller particle size can fall onto the screen 41 below. At this time, the reciprocating mechanism 3 cooperates with the reciprocating rotating mechanism 5, so that the connecting rod 4 drives the screen 41 to rotate back and forth, so that the fertilizer with smaller particle size can be screened out and enter the collecting box 7 arranged below, and the fertilizer with appropriate particle size enters the discharge box 6, and is prevented in advance at the bottom of the discharge hopper 61 from collecting the screened high-quality fertilizer.

[0024] The reciprocating mechanism 3 includes a servo motor 31 fixedly mounted on one side of the box body 1, and a plurality of rotating shafts 32 are rotatably connected inside the box body 1. The output end of the servo motor 31 is fixedly connected to one end of one of the rotating shafts 32. A gear 33 is fixedly mounted on the outer side of each rotating shaft 32. The two gears 33 are meshed with each other. One end of the two rotating shafts 32 is fixedly mounted with a gear 2 34. A rack 35 is fixedly mounted on one side of the screen frame 2. The two gears 2 34 are meshed with the rack 1 35. The servo motor 3 is started. 1, one of the rotating shafts 1 32 is driven to rotate through the output end, and because the gears 1 33 are meshed with each other, the other two rotating shafts 1 32 can be driven to rotate at the same time, and the two rotating shafts 1 32 that are far away from each other drive the gear 2 34 at one end to rotate at the same time, and the gear 2 34 and the rack 1 35 are meshed with each other, so that the screen frame 2 can reciprocate left and right inside the box body 1, so that the fertilizer inside can be screened, and the fertilizer with larger particle size can be effectively intercepted, and the fertilizer with smaller particle size can fall onto the screen 41 below.

[0025] The reciprocating rotating mechanism 5 includes a rotating shaft 2 51 which is rotatably connected inside the box body 1, and the rotating shaft 2 51 is transmission-connected to one of the rotating shafts 1 32.

Since the rotating shaft 2 51 is transmission-connected to one of the rotating shafts 1 32, the rotating shaft 1 32 drives the rotating shaft 2 51 to rotate at the same time. By utilizing the mutual cooperation between the rotating shaft 2 51, the gear 3 52 and the gear 4 53, the connecting rod 4 drives the screen 41 to reciprocate within a certain range, so that the fallen fertilizer can be screened, so that the fertilizer with smaller particle size falls into the collection box 7 below, and the fertilizer with appropriate particle size enters the discharge box 6, further improving the screening effect of the device.

[0026] A baffle 8 is rotatably connected to one side of the box body 1, and the baffle 8 blocks the slide 12. Two buckles 81 are fixedly installed on one side of the box body 1. The box body 1 is fixedly connected to the baffle 8 by the buckles 81, which can block the slide 12 to prevent dust caused by the screening process from falling to the outside, thereby improving the practicability of the device.

[0027] A plurality of springs 14 are fixedly installed between the discharge port 13 and the screen 41 . The elastic force and tension of the springs 14 can prevent the screen 41 from colliding with the box body 1 during rotation, thereby increasing the service life of the screen 41 .

[0028] A drainage plate 62 is fixedly installed at the bottom of the inner wall of the discharge box 6, and one side of the discharge hopper 61 is inclined toward the opening. Since the drainage plate 62 has a certain slope, the fertilizer inside can quickly enter the discharge hopper 61 below, thereby preventing the fertilizer from causing blockage inside the discharge box 6.

[0030] The operating principle of this embodiment is as follows: when in use, the fertilizer to be screened is poured into the feed hopper 11, so that it falls into the interior of the screen frame 2 below, and then the servo motor 31 is started, and one of the rotating shafts 32 is driven to rotate through the output end, and the rotating shaft 32 drives the outer gear 33 to rotate at the same time, and the gears 33 are meshed with each other to make the other two rotating shafts 32 rotate at the same time, and the two rotating shafts 32 farthest from each other drive the gear 2 34 at one end to rotate at the same time, and the gear 2 34 is meshed with the rack 1 35 to drive the screen frame 2 to move back and forth left and right, so that the fertilizer inside slides. The connecting rod 4 drives the screen 41 to rotate back and forth, thereby screening the fertilizer with a larger particle size and intercepting the fertilizer with a smaller particle size, while the fertilizer with a smaller particle size falls onto the screen 41 arranged below. Since one of the rotating shafts 32 is connected to the rotating shaft 2 51 in transmission, it drives the rotating shaft 2 51 to rotate at the same time. By utilizing the cooperation of the rotating shaft 2 51, the gear 3 52 and the gear 4 53, the connecting rod 4 drives the screen 41 to rotate back and forth, thereby screening the fertilizer with a smaller particle size and making it fall into the collecting box 7 below, while the fertilizer with a suitable particle size will enter the discharging box 6 on one side, thereby completing the screening of the fertilizer and further improving the quality of the fertilizer.
