Description

Technical Field

[0001] This utility model relates to the field of organic fertilizer screening technology, specifically a screening device for organic fertilizer processing. Background Technology

[0002] Organic fertilizer is an organic substance derived from plants, animals, and microorganisms. It is usually made by biological decomposition or artificial methods. The main function of organic fertilizer is to provide corresponding nutrients to crops and soil. Screening equipment is used in the processing and production of organic fertilizer. Screening can remove impurities from organic fertilizer and ensure that the particle size of organic fertilizer is uniform, which is convenient for subsequent production and use.

[0003] Traditional screening equipment for organic fertilizer processing suffers from several drawbacks. If the organic fertilizer doesn't fall evenly onto the screen, fertilizer accumulates in some areas while other areas operate idle, impacting screening efficiency. Therefore, we propose a new screening device for organic fertilizer processing to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a screening device for organic fertilizer processing to solve the problems mentioned in the background art.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4This utility model provides an embodiment: a screening device for organic fertilizer processing, including a screening box 1, a support frame 2 installed at the bottom of the screening box 1, a feed hopper 16 installed on the left side of the top of the screening box 1, a dispersing seat 15 installed at the bottom of the feed hopper 16, and a dispersing plate 21 installed inside the dispersing seat 15. Several dispersing plates 21 are arranged in a manner that allows the organic fertilizer to fall at different positions above the first filter screen 10. The top of the screening box 1... The screen is equipped with a first filter screen 10, a third discharge plate 9 installed on one side of the first filter screen 10, and a second filter screen 12 installed at the bottom of the first filter screen 10. The second filter screen 12 is movably installed inside the screening box 1, and a second discharge plate 8 is installed on one side of the second filter screen 12. An inclined plate 6 is installed at the bottom of the interior of the screening box 1, and a first discharge plate 7 is installed on one side of the inclined plate 6. Fixing blocks 13 are provided on both sides of the bottom of the first filter screen 10 and the second filter screen 12, and one end of each fixing block 13 is connected to the screen. The inner wall of the screening box 1 is fixed, and the top of each fixing block 13 is fixed with a telescopic spring 14. The top of the telescopic spring 14 is fixed to the bottom of the first filter screen 10 and the second filter screen 12 respectively. A second servo motor 20 is installed at the rear end of the screening box 1. A first rotating shaft 22 is installed at the bottom of the second servo motor 20. A first bevel gear 24 is installed on the outer wall of the first rotating shaft 22. A second bevel gear 25 is meshed on one side of the first bevel gear 24. A second rotating shaft 25 is installed on one side of each second bevel gear 25. 3. The second rotating shaft 23 extends into the interior of the screening box 1. Cams 11 are installed on the outer side walls of the second rotating shaft 23. Several telescopic springs 14 are provided, and the several telescopic springs 14 are symmetrically distributed about the central axis of the first filter screen 10 and the second filter screen 12. Several cams 11 are provided, and the several cams 11 are symmetrically distributed about the central axis of the first filter screen 10 and the second filter screen 12, so that the first filter screen 10 and the second filter screen 12 can stably move up and down to screen the organic fertilizer.

[0024] Specifically, such as Figure 1 and Figure 2 As shown, the organic fertilizer falls into the inside of the feed hopper 16 and is then introduced into the inside of the screening box 1. During the introduction, the material falls through the dispersion plates 21 that are evenly distributed inside the dispersion seat 15 and falls to different positions above the first filter screen 10 for screening.

[0025] Each feed hopper 16 has a mounting base 17 installed at its front end. Each mounting base 17 has a first servo motor 18 installed at one end, and each first servo motor 18 has a crushing roller 19 installed at one end.

[0026] Specifically, such as Figure 1 and Figure 2As shown, the two sets of first servo motors 18 are started to drive the two sets of crushing rollers 19 to rotate in opposite directions. The organic fertilizer to be screened is then poured into the inside of the feed hopper 16 and introduced into the inside of the screening box 1 for screening. When the organic fertilizer enters the inside of the feed hopper 16, the rotating crushing rollers 19 can crush the organic fertilizer, so that the agglomerated organic fertilizer is broken up, and the screening effect of the organic fertilizer is better.

[0027] A fixed rod 3 is installed at the bottom of the support frame 2. An adjusting rod 4 is movably installed inside the fixed rod 3. A stable support 5 is installed at the bottom of each adjusting rod 4. There are three sets of stable supports 5. The three sets of stable supports 5 are distributed at equal intervals at the bottom of the support frame 2, which greatly increases the stability of the screening equipment. The inner side wall of the fixed rod 3 is uniformly provided with internal threads. The fixed rod 3 and the adjusting rod 4 form a threaded connection, which can adjust the stable support 5 and make it move up and down.

[0028] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, after the screening equipment is placed, the adjusting rod 4 is rotated in sequence to move it downwards, which pushes the stabilizing support 5 downwards to fit against the ground, thus supporting the screening equipment and making the screening equipment stable.

[0029] Working Principle: In use, the screening device is placed and the adjusting rod 4 is rotated downwards to move the stabilizing support 5 downwards to the ground, supporting the screening equipment. The second servo motor 20 is activated, driving the first rotating shaft 22 to rotate. The rotation of the first rotating shaft 22 drives the first bevel gear 24 to rotate, which in turn drives the meshing second bevel gear 25 to rotate. The rotation of the second bevel gear 25 drives the second rotating shaft 23 to rotate, which in turn drives the cam 11 to rotate. Simultaneously, the elastic potential energy of the telescopic spring 14 causes the first filter screen 10 and the second filter screen 12 to bounce up and down. At the same time, two sets of first servo motors 18 are activated, driving two sets of crushing rollers 19 to rotate in opposite directions. The rotating crushing rollers 19 can crush organic fertilizer... The crushing process breaks up the clumps of organic fertilizer. After crushing, the fertilizer is fed into the dispersing seat 15 through the feed hopper 16. It then falls onto the first filter screen 10 at different positions through the dispersing plates 21 that are evenly distributed inside the dispersing seat 15. Organic fertilizer larger than the first filter screen 10 stays above the first filter screen 10 and is discharged through the third discharge plate 9 on one side. Organic fertilizer smaller than the first filter screen 10 falls onto the second filter screen 12 and is screened by the second filter screen 12. During screening, organic fertilizer larger than the second filter screen 12 stays above the second filter screen 12 and is discharged through the second discharge plate 8 on one side. Organic fertilizer smaller than the second filter screen 12 falls onto the inclined plate 6 at the bottom of the screening box 1 and slides to one side through the first discharge plate 7 to be discharged, thus completing the screening of organic fertilizer.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
