A feedstuff foreign matter rapid screening device

Abstract

This utility model relates to the field of feed foreign object screening technology and discloses a rapid foreign object screening device for feed raw materials. An elastic plate is detachably mounted on the outer side of the base via fixing blocks, bolts, and nuts. A sieve plate is detachably mounted on the top of the elastic plate via fixing blocks, bolts, and nuts. A dual-axis servo motor drives the turntable and eccentric shaft to rotate. The eccentric shaft drives the drive rod to reciprocate, causing the sieve plate to move back and forth. Simultaneously, the sieve plate automatically returns to its original position due to the influence of the elastic plate. The swaying movement of the sieve plate causes large particles of foreign matter in the raw material to rise and be exposed, making them easy for personnel to pick out. Small particles of foreign matter fall into the ash collection trough. The raw material rolls down to the discharge hopper and is discharged. The stepped protrusions further impede foreign matter and dust in the raw material, while the magnet attracts iron powder, thus achieving rapid screening of foreign objects from the feed raw materials.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a rapid screening device for foreign objects in feed raw materials, which has the following beneficial effects:

[0016] 1. This rapid foreign object screening device for feed raw materials uses a dual-axis servo motor to drive a turntable and an eccentric shaft to rotate. The eccentric shaft drives a drive rod to reciprocate, causing the screen plate to move back and forth. Simultaneously, the screen plate automatically returns to its original position due to the influence of an elastic plate. The swaying movement of the screen plate causes large particles of foreign matter in the raw material to rise and be exposed, making it easy for personnel to pick them out. Small particles of foreign matter fall into the dust collection trough. The raw material rolls down to the discharge hopper and is discharged. The stepped protrusions can further block foreign matter and dust in the raw material, and the magnet can adsorb iron powder in the raw material, thereby achieving rapid screening of foreign matter in feed raw materials and improving the processing efficiency of feed raw materials.

[0017] 2. This rapid foreign matter screening device for feed raw materials works by pulling the lever with a handle, which causes the scraper to move in the ash collection trough. The scraper can scrape and discharge the dust in the ash collection trough, thus treating the accumulated dust. By lifting or pushing the slide rod up or down and then tightening it with locking bolts, the tilt of the baffle can be controlled to ensure that the raw material falls to the high tilt position of the screen plate, which facilitates the rolling of the raw material and screens out small dust particles.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] Please see Figures 1-4 A rapid foreign object screening device for feed raw materials includes four support legs 1. A base 2 is fixedly installed on the top of the support legs 1. A dust collection trough 3 is opened on the top of the base 2. The bottom wall of the dust collection trough 3 is inclined at 10°-20° to facilitate dust cleaning. An elastic plate 5 is detachably installed on the outer side of the base 2 through fixing blocks 4, bolts and nuts. The elastic plate 5 is Z-shaped. A screen plate 6 is detachably installed on the top of the elastic plate 5 through fixing blocks 4, bolts and nuts. The screen plate 6 can shake relative to the base 2 through the elastic plate 5 to achieve screening of raw materials.

[0028] Please see Figures 1-4A dual-axis servo motor 7 is fixedly installed on one side of the top of the base 2. A turntable 8 is fixedly installed at the output end of the dual-axis servo motor 7. An eccentric shaft 9 is fixedly installed on the surface of the turntable 8. A drive rod 10 is movably installed on the outer side of the eccentric shaft 9. The drive rod 10 is located on the outer side of the elastic plate 5. A connecting rod 11 is movably installed at the other end of the drive rod 10. The connecting rod 11 is fixedly installed on both sides of the screen plate 6. The dual-axis servo motor 7 drives the turntable 8 and the eccentric shaft 9 to rotate, and the drive rod 10 drives the screen plate 6 to reciprocate.

[0029] Please see Figure 5 A bracket 12 is fixedly installed on the outer wall of the base 2. A hopper 13 is inserted through the top of the bracket 12. A baffle 14 is hinged to the bottom of the hopper 13. One end of the baffle 14 extends to the position of the bracket 12 and is inclined. The raw material is poured into the hopper 13 and rolls onto one end of the screen plate 6 as the baffle 14 is inclined. As the screen plate 6 shakes, the raw material is screened.

[0030] Please see Figures 5-6 A flexible rope 19 is fixedly mounted on the side of the baffle 14 via a mounting base 18. A sliding rod 20 is fixedly mounted on the top of the flexible rope 19. The sliding rod 20 is inserted inside a sliding sleeve 21, which is fixedly mounted on the side of the bracket 12. A nut 22 is fixedly mounted on the side of the sliding sleeve 21, and a locking bolt 23 is threaded into the nut 22. The sliding rod 20 is detachably mounted to the sliding sleeve 21 via the nut 22 and the locking bolt 23. Loosening the locking bolt 23 allows the sliding rod 20 to be pulled up or pushed down, which in turn causes the baffle 14 to rotate upwards or downwards, thereby controlling the tilt angle of the baffle 14 and sealing the bottom of the hopper 13.

[0031] Please see Figures 3-4 A discharge hopper 15 is fixedly installed on one side of the sieve plate 6. The bottom wall of the sieve plate 6 is inclined downward at 5°-10° towards the discharge hopper 15, so that the raw material can roll down to a lower position as the sieve plate 6 shakes. Stepped protrusions 16 are fixedly installed on the surface of the sieve plate 6. When the raw material rolls to the positions of multiple stepped protrusions 16, it is convenient to intercept small impurities mixed in with the raw material. A magnet 17 is embedded in the bottom wall of the discharge hopper 15. When the raw material rolls above the magnet 17, it can adsorb iron floating or particles mixed in with the raw material.

[0032] Please see Figures 2-3 and Figure 7 A scraper 24 is slidably installed on the bottom wall of the ash collection trough 3. A pull rod 25 is fixedly installed on one side of the scraper 24, and a handle 26 is fixedly installed on one side of the pull rod 25. A sliding seat 27 is slidably fitted on the outer side of the pull rod 25, and the sliding seat 27 is fixedly installed at the outlet position of the ash collection trough 3. The pull rod 25 can be driven to slide in the sliding seat 27 by the handle 26, and then the scraper 24 will scrape the dust off the bottom wall of the ash collection trough 3.

[0033] Working principle: During use, the dual-axis servo motor 7 drives the turntable 8 and eccentric shaft 9 to rotate. The eccentric shaft 9 drives the drive rod 10 to reciprocate, which in turn causes the screen plate 6 to move back and forth. At the same time, the screen plate 6 will automatically return to its original position due to the influence of the elastic plate 5. The swaying movement of the screen plate 6 will cause large particles of foreign matter in the raw material to move upward and be exposed, making it easier for personnel to pick them out. Small particles of foreign matter will fall into the ash collection trough 3. The raw material will roll down to the discharge hopper 15 and be discharged. The stepped protrusions 16 can further block foreign matter and dust in the raw material, and the magnet 17 can adsorb iron powder in the raw material, thereby realizing the rapid screening of foreign matter in feed raw materials and improving the processing efficiency of feed raw materials.

[0034] Pulling the lever 25 by the handle 26 causes the scraper 24 to move in the ash collection trough 3, which scrapes and discharges the dust in the ash collection trough 3, thus treating the accumulated dust. By lifting or pushing the slide bar 20 and then tightening it with the locking bolt 23, the tilt control of the baffle 14 is achieved, ensuring that the raw material falls onto the inclined high position of the screen plate 6, which facilitates the rolling of the raw material and screens out small dust particles.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
