[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1 - 4 , an embodiment provided by the present invention: A feed screening device provided with an auxiliary plate, including an outer shell 1, a material storage bin 2 is fixedly installed on the top of the outer shell 1, a first motor 3 is fixedly installed at the rear end of the outer shell 1, a stirring rod 4 is fixedly connected to the front end of the first motor 3, and a screening mechanism 5 is arranged inside the outer shell 1.

[0025] The screening mechanism 5 includes a second motor 501, a cam 502, a first limit block 503, a first slider 504, a connecting plate 505, a pulley 506, a gear 507, a first fixing plate 508, a second limit block 509, a second slider 510 and a filter plate 511. A second motor 501 is arranged inside the outer shell 1, a cam 502 is arranged at the front end of the second motor 501, a first limit block 503 is arranged on the inner wall of the outer shell 1, a first slider 504 is arranged inside the first limit block 503, a connecting plate 505 is arranged at the rear end of the first slider 504, a pulley 506 is arranged at the right end of the connecting plate 505, a gear 507 is arranged at the left end of the connecting plate 505, a first fixing plate 508 is arranged on the inner wall of the outer shell 1, a second limit block 509 is arranged below the first fixing plate 508, a second slider 510 is arranged inside the second limit block 509, a filter plate 511 is arranged at the rear end of the second slider 510, and a return component 7 is arranged between the first limit block 503 and the connecting plate 505;

[0026] Through the settings of the screening mechanism 5, the return component 7 and the auxiliary plate 6, this device solves the problem that the screening stability cannot be guaranteed, resulting in easy accumulation and blockage of sundries in the screening process, thereby reducing the use effect of the device.

[0027] Further, the return component 7 includes a second fixing plate 701, fixing columns 702, movable columns 703 and springs 704. The front end of the connecting plate 505 is fixedly connected to the second fixing plate 701. Two groups of fixing columns 702 are fixedly connected to the right side of the first limiting block 503. The movable columns 703 are movably connected within the fixing columns 702. Springs 704 are arranged within the movable columns 703. The two ends of the springs 704 respectively abut against the movable columns 703 and the springs 704. The right end of the movable column 703 is fixedly connected to the second fixing plate 701. As Figure 3 shown, this structure is used to push the movable column 703 to move rightward within the fixing column 702 through the restoring action of the spring 704 to reset the second fixing plate 701.

[0028] Further, the second motor 501 is fixedly installed inside the housing 1 on the right side of the storage bin 2. The rear end of the cam 502 is fixedly connected to the second motor 501. The front end of the first limiting block 503 is fixedly connected to the inner wall of the housing 1. The outer side of the first slider 504 is connected to the first limiting block 503 well. The front end of the connecting plate 505 is fixedly connected to the first slider 504. The pulley 506 is located on the right side of the connecting plate 505 and is fixedly connected to the connecting plate 505. The gear 507 is located on the left side of the connecting plate 505 and is rotatably connected to the connecting plate 505. The first fixing plate 508 is located above the gear 507 and the front end is fixedly connected to the inner wall of the housing 1. The second limiting block 509 is located below the gear 507 and the front end is fixedly connected to the inner wall of the housing 1. The second slider 510 is located within the second limiting block 509 and is movably connected to the second limiting block 509. The front end of the filter plate 511 is fixedly connected to the second slider 510. Rack teeth are provided on the sides of the first fixing plate 508 and the second slider 510 facing the gear 507, and the rack teeth mesh with the gear 507. As Figure 2 shown, this structure is used to drive the cam 502 to rotate through the second motor 501. When the cam 502 rotates, it pushes the pulley 506 to move the connecting plate 505 to move leftward along the first limiting block 503 and the first fixing plate 508, and drives the second slider 510 to move leftward within the second limiting block 509 through the gear 507, so that the discharge port 8 at the filter plate 511 overlaps with the communication hole at the auxiliary plate 6, performing screening treatment on the feed machinery and enabling the filter plate 511 to move horizontally stably.

[0029] Further, communication holes are formed on the surface of the filter plate 511. The inner wall of the housing 1 is fixedly connected with an auxiliary plate 6. A discharge port 8 corresponding to the position of the communication hole of the filter plate 511 is formed within the auxiliary plate 6. A scraper 9 is fixedly connected to the inner side of the discharge port 8. The filter plate 511 is in fit with the auxiliary plate 6. As Figure 4As shown, when the structure is reset through the filter plate 511, it moves by fitting the filter plate 511 to the auxiliary plate 6. Under the action of the scraper 9, the feed between the communication holes of the filter plate 511 and the auxiliary plate 6 is removed.

[0030] Furthermore, a first collision block 10 is fixedly connected to the bottom of the first limit block 503, and a second collision block 11 is fixedly connected to the front end of the auxiliary plate 6. The first collision block 10 and the second collision block 11 are on the same axis, and the cross-sections of both the first collision block 10 and the second collision block 11 are rectangular. As Figure 2 shown, when the structure is reset through the connecting plate 505, the filter plate 511 is reset, and the first collision block 10 and the second collision block 11 are impacted, causing the filter plate 511 to vibrate and preventing the feed from getting stuck in the communication holes.

[0031] Furthermore, the first slider 504 and the second slider 510 are T-shaped, the inner groove of the first limit block 503 is adapted to the first slider 504, and the inner groove of the second limit block 509 is adapted to the second slider 510. As Figure 2 shown, due to the T-shaped first slider 504 and second slider 510, the first slider 504 can move stably within the first limit block 503, improving stability.

[0032] Furthermore, the gear 507, the first fixing plate 508, and the second slider 510 are on the same axis, and the length of the second slider 510 is one-third of that of the first fixing plate 508. As Figure 2 shown, this structure is used for the second slider 510 to move stably within the second limit block 509. First, the gear 507 contacts the rack at the first fixing plate 508 to determine the rotation direction of the gear 507, and then it contacts the rack at the second slider 510.

[0033] Working principle: When in use, as Figure 1 shown, the feed is placed in the storage bin 2, the first motor 3 is started to drive the stirring rod 4 to rotate, and the feed in the storage bin 2 is stirred. As Figure 2 shown, then the second motor 501 is started. The second motor 501 drives the cam 502 to rotate. When the cam 502 rotates, it pushes the pulley 506 to move the connecting plate 505 to the left along the first limit block 503. At this time, the gear 507 first contacts the rack at the first fixing plate 508 and rotates along the rack at the first fixing plate 508, and then contacts the rack at the second slider 510. The gear 507 drives the second slider 510 to move to the left within the second limit block 509, making the discharge port 8 at the filter plate 511 overlap with the communication hole at the auxiliary plate 6, and the feed drops from the discharge port 8 for screening and reasonable distribution of the feed. As Figure 3As shown, as the cam 502 rotates, when the protruding part of the cam 502 is not in contact with the pulley 506, under the restoring action of the spring 704, the movable column 703 is pushed to move rightward in the fixed column 702, resetting the second fixing plate 701. The filter plate 511 moves by fitting with the auxiliary plate 6. Under the action of the scraper 9, the feed between the communication holes of the filter plate 511 and the auxiliary plate 6 is cleaned. When the connecting plate 505 is reset, the filter plate 511 is reset, and the second collision block 11 impacts the first collision block 10, causing the filter plate 511 to vibrate, preventing the feed from getting stuck in the communication holes. The above is the entire working principle of the present utility model.

[0034] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, in any regard, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be encompassed within the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
