Description

Technical Field

[0001] This utility model relates to the field of vibrating screen technology, specifically a corn crushing vibrating screen with a dust adsorption structure. Background Technology

[0002] When processing corn into feed, the corn needs to be crushed into small pieces, and then the corn crushed material is screened using a corn crushed material vibrating screen. However, the existing corn crushed material vibrating screens still have certain defects in use, such as:

[0003] When vibrating and screening corn crushers, a significant amount of dust is generated. Some vibrating screens have an outer shell to prevent dust from flying around. However, after screening, it takes a long time for the dust to settle naturally, which is time-consuming. Most of these screens cannot effectively absorb the dust. Furthermore, existing vibrating screens for corn crushers typically use an inclined screen plate for screening. After the corn crushers are vibrated and screened, they slide directly off the screen plate, resulting in only one screening operation. This leads to poor screening efficiency, requiring the corn crushers to be fed back into the vibrating screen for screening again. Most of these screens cannot achieve the problem of cyclic screening. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This corn crushing vibrating screen with a dust adsorption structure draws dust from the machine casing into the dust collection box by starting the exhaust fan, leaving the dust on the filter screen. The drive motor then drives the brush plate to scrape off the dust adhering to the filter screen, which falls into the collection box, thus allowing the corn crushing vibrating screen to adsorb the dust.

The specific details are as follows:

[0016] 1. By starting the exhaust fan, outside air is filtered through the dust filter and enters the machine casing through the L-shaped pipe. Then, the dust inside the machine casing is sucked into the long trough and sent into the dust collection box. After being filtered through the filter screen, the dust is left on the filter screen. Then, the drive motor is started to drive the brush plate to rotate, scraping off the dust attached to the filter screen and letting it fall into the collection box. In this way, the corn crushing vibrating screen can adsorb the dust.

[0017] 2. By starting the electric actuator to drive the connecting plate to rotate the rectangular frame, the screen plate is tilted. Then, the vibrating motor is started to drive the screen plate to vibrate and screen the corn fragments on the screen plate. When the corn fragments on the screen plate vibrate to one side, the electric actuator is started again to tilt the screen plate in the opposite direction and vibrate the corn fragments to the other side of the screen plate, so that the corn fragments can be circulated and screened by the vibrating screen.

The dust collection box 705 is placed on one side of the housing 1. A collection box 706 slides through the front of the inner wall of the dust collection box 705. An exhaust fan 707 is connected to the top of the dust collection box 705 through a pipe. A filter 708 is connected to the inner wall of the dust collection box 705 near the air supply pipe 704. A drive motor 709 is connected to the upper surface of the filter 708 through a motor base. The output end of the drive motor 709 passes through the inner wall of the filter 708 and is connected to a brush plate 710 through a coupling. The brush plate 710 abuts against the bottom of the filter 708.

[0029] In practice, the exhaust fan 707 is started to extract the air from the dust collection box 705. The outside air is filtered through the dust filter screen 702 and enters the machine casing 1 through the L-shaped pipe 701. Then, the dust in the machine casing 1 is sucked into the long trough 703 and sent into the dust collection box 705 through the air supply pipe 704. After being filtered through the filter screen 708, the air is discharged and the dust is left on the filter screen 708. Then, the drive motor 709 is started to drive the brush plate 710 to rotate, scraping off the dust attached to the filter screen 708 and letting it fall into the collection box 706. Then, the collection box 706 is pulled out and dumped so that the corn crushing vibrating screen can adsorb the dust.

[0030] See Figure 1 and Figures 4-7It can be seen that the screening mechanism 5 includes: a rectangular frame 501, an L-shaped plate 502, a slide rod 503, a screen plate 504, a spring 505, a dust cover 506, a connecting plate 507, an electric push rod 508, and a vibrating motor 509. The rectangular frame 501 rotates through the inner wall of the housing 1. The L-shaped plates 502 are connected to the top and bottom of the rectangular frame 501. The slide rod 503 is connected between the two sets of L-shaped plates 502. The screen plate 504 is slidably connected to the slide rod 503. The bottom of the screen plate 504 is connected to the motor base. A vibration motor 509 is connected to the slide rod 503. Two sets of springs 505 are sleeved on the outside of the slide rod 503. The springs 505 abut against the L-shaped plate 502 and the sieve plate 504. A dust cover 506 is provided on the outside of the slide rod 503 and the springs 505.

An electric push rod 508 is rotatably connected to the front of the connecting plate 507. The other end of the electric push rod 508 is rotatably connected to the front of the machine casing 1.

[0031] In practice, the electric actuator 508 is activated to drive the connecting plate 507 to rotate the rectangular frame 501, tilting the screen plate 504. Then, the vibration motor 509 is activated to drive the screen plate 504 to vibrate. The screen plate 504 slides along the slide bar 503, and the compression spring 505 rebounds, screening the corn fragments on the screen plate 504. When the corn fragments on the screen plate 504 vibrate to one side, the electric actuator 508 is activated again to tilt the screen plate 504 in the opposite direction, and then the corn fragments are vibrated to the other side of the screen plate 504. This cycle is repeated to allow the corn fragments to be screened by the vibrating screen.

[0032] In summary: When using this type of corn crusher vibrating screen with a dust adsorption structure, firstly, open the feed door 2 and pour the corn crusher into the machine casing 1, where it falls onto the screen plate 504. Then, start the electric actuator 508 to tilt the screen plate 504, and then start the vibrating motor 509 to drive the screen plate 504 to vibrate, screening the corn crusher. At the same time, the corn crusher slides along the tilt direction of the screen plate 504, sliding to one side of the screen plate 504. Then, start the electric actuator 508 to tilt the screen plate 504 in the opposite direction, sliding the corn crusher to the other side of the screen plate 504. This process is repeated continuously. Smaller pieces of corn crusher pass through the screen plate 504 and fall onto the guide plate 6, while larger pieces remain on the screen plate 504. Then, start... The exhaust fan 707 draws the dust generated by the vibrating screen inside the casing 1 into the dust collection box 705. The dust is filtered through the filter screen 708 and remains on the filter screen 708. Then, the drive motor 709 is started to drive the brush plate 710 to rotate, scraping off the dust adhering to the filter screen 708 and letting it fall into the collection box 706. The dust inside the casing 1 is quickly removed to prevent dust from floating out during material removal. Then, the electric discharge door 4 at the front is opened to slide out the smaller corn pieces on the guide plate 6. Then, the electric discharge door 4 on the side of the casing 1 is opened to slide out the larger corn pieces on the screen plate 504. The collection box 706 is then pulled out and the collected dust is dumped. The contents not described in detail in this description are existing technologies known to those skilled in the art.
