Description

Technical Field

[0001] This utility model relates to the field of organic fertilizer sieving, and in particular to an organic fertilizer sieve. Background Technology

[0002] Organic fertilizer is a carbon-containing material, mainly derived from plants and animals. Organic fertilizer can not only provide nutrients for crops, but also increase the organic matter in the soil and promote the reproduction of microorganisms, which has led the country to vigorously promote the replacement of chemical fertilizers with organic fertilizers.

[0003] However, existing screens have low screening efficiency, which makes it impossible to effectively remove impurities and clumps from organic fertilizers, affecting the particle size uniformity and application effect of organic fertilizers. At the same time, it is inconvenient to replace the screens, making the operation cumbersome and time-consuming when the screens are worn or the mesh size needs to be adjusted according to different screening requirements, thus reducing the flexibility and efficiency of the overall screening operation. To address these issues, we propose an organic fertilizer screen. Utility Model Content

[0022] Please see Figure 1-4In this utility model, an organic fertilizer screen includes a screening box 1. The upper surface of the screening box 1 is connected to a hopper 6. The upper surface of the hopper 6 is hinged to a protective component 2. The inner wall of the screening box 1 is provided with a screening component 4, which includes two sliding grooves 401, two sliders 402, a support frame 403, a screening screen 404, a pull groove 405, two threaded holes 406, and two fastening bolts 407. The outer surface of the screening box 1 is connected to an auxiliary component 3, which includes a first motor 301, a threaded rod 302, two first bearings 303, a nut 304, a moving frame 305, and a screening roller 306. The outer surface of the screening box 1 is connected to a discharge component 5, which includes a second motor 501, a rotating column 502, a second bearing 503, and a spiral blade 504.

[0023] The first motor 301 is connected to the outer surface of the screening box 1. The output end of the first motor 301 is connected to a threaded rod 302. Two first bearings 303 are embedded in the inner wall of the screening box 1. The inner rings of the first bearings 303 are connected to the outer surface of the threaded rod 302. A nut 304 is threadedly connected to the outer surface of the threaded rod 302. A movable frame 305 is connected to the bottom surface of the nut 304. A screening roller 306 is hinged inside the movable frame 305 by a pin. The first motor 301 drives the threaded rod 302 to rotate, causing the nut 304 to drive the movable frame 305 to adjust on the outer surface of the threaded rod 302, thereby allowing the screening roller 306 to crush and loosen the organic fertilizer. A slide rod 7 is connected to the inner wall of the screening box 1. A movable block 8 is slidably connected to the outer surface of the slide rod 7. The outer surface of the movable block 8 is connected to the outer surface of the movable frame 305. Through the cooperation of the slide rod 7 and the movable block 8, the movable frame 305 can be effectively assisted, increasing the stability of the movable frame 305 during adjustment.

[0024] Two chutes 401 are jointly formed on the inner wall of the screening box 1. Two sets of sliders 402 are slidably connected to the inner walls of the two chutes 401. A support frame 403 is connected to the side of the two sets of sliders 402 that are close to each other. A screening screen 404 is connected inside the support frame 403. A pull groove 405 is formed on the outer surface of the support frame 403. Two threaded holes 406 are jointly formed on the outer surface of the screening box 1. Fastening bolts 407 are threadedly connected to the inner walls of the two threaded holes 406. The bottom end of each fastening bolt 407 is in contact with the upper surface of the support frame 403. By rotating the fastening bolt 407, the fastening bolt 407 rotates on the inner wall of the threaded hole 406, thereby loosening the fastening bolt 407 from the support frame 403. Then, the pull groove 405 is pulled, and the support frame 403 and the screening screen 404 are pulled out by the cooperation of the chutes 401 and the sliders 402.

[0025] The second motor 501 is connected to the outer surface of the screening box 1. The output end of the second motor 501 is connected to the rotating column 502. The second bearing 503 is embedded in the inner wall of the screening box 1. The inner ring of the second bearing 503 is connected to the outer surface of the rotating column 502. The outer surface of the rotating column 502 is connected to the spiral blades 504. The second motor 501 drives the rotating column 502 to rotate, causing the spiral blades 504 to rotate on the outer surface of the rotating column 502, thereby causing the spiral blades 504 to carry the organic fertilizer out. The protective component 2 includes a cover plate 201 and a pull rod 202. The cover plate 201 is hinged to the upper surface of the hopper 6. The upper surface of the cover plate 201 is connected to the pull rod 202. Through the cooperation of the cover plate 201 and the pull rod 202, the organic fertilizer dust can be effectively prevented from flying or the material from splashing out, protecting the working environment and the health of the operators, and improving the safety of the operation.

[0026] The working principle of this utility model is as follows:

[0027] In use, firstly, the cover plate 201 is opened by pulling rod 202, and the organic fertilizer to be screened is put into the screening box 1 from hopper 6. Then, the first motor 301 is started, so that the threaded rod 302 rotates using the first bearing 303, thereby causing the nut 304 to drive the moving frame 305 to adjust under the cooperation of slide rod 7 and moving block 8. Then, the screening roller 306 crushes and loosens the organic fertilizer on the screening screen 404 under the action of the pin shaft, preventing the organic fertilizer from clumping and clogging the screening screen 404. Then, the second motor 501 is started, so that the rotating column 502 rotates using the second bearing 503, thereby causing the spiral blade 504 to discharge the screened organic fertilizer. Finally, the fastening bolt 407 is rotated, so that the fastening bolt 407 rotates in the inner wall of the threaded hole 406, thereby loosening the support frame 403. Further, through the pull groove 405, the support frame 403 drives the screening screen 404 to be removed under the cooperation of slide groove 401 and slider 402 for quick replacement.
