Description

Technical Field

[0001] The utility model relates to the technical field of feed production, in particular to a grading screening machine used for feed production. Background Art

[0002] One of the criteria for judging high-quality feed is whether the particle size of the feed is uniform. However, it is difficult to ensure the uniformity of feed particles during the production process of feed. Therefore, in order to obtain high-quality feed, after the production of the feed is completed, a grading screening machine is needed to screen the feed to remove larger feed particles and smaller powder particles, so as to obtain high-quality feed. This can ensure the uniformity of the fineness of the feed. The current feed powder screening machine uses multiple screen barrels with different mesh sizes to connect during screening, and uses a motor to drive the screen barrel to rotate, and cooperates with a scraper to scrape the feed onto the next level of the screen. In this process, the feed is subjected to excessive extrusion force and strong collision force. When screening the feed particles, the feed is easily crushed, and the integrity of the feed cannot be maintained, affecting the quality of the finished product. In view of this, we propose a grading screening machine for feed production. Utility Model Content

A screening device 3 is provided on the inner side of the left frame plate 11, and a driving device 4 is provided on one side of the screening device 3. The driving device 4 includes two tooth plates 43 and a half gear 41 meshed between the two tooth plates 43, wherein only half of the outer surface of the half gear 41 is provided with teeth, and a second motor 42 is fixedly provided on one side of the right frame plate 12. The second motor 42 passes through one side of the right frame plate 12 and is fixedly connected to the half gear 41. The top and bottom ends of the two tooth plates 43 are fixedly connected with a U-shaped connecting rod 44. When the second motor 42 drives the half gear 41 to rotate, the two tooth plates 43 are meshed with the half gear 41 to make the two tooth plates 43 move back and forth up and down, and at the same time drive the U-shaped connecting rod 44 to move.

[0025] The screening device 3 includes a primary screening plate 31 and a secondary screening plate 32 arranged at the lower side of the primary screening plate 31. Screening holes are provided in the middle of the primary screening plate 31 and the secondary screening plate 32, and the diameter of the screening holes provided in the primary screening plate 31 is larger than the diameter of the screening holes provided in the secondary screening plate 32. Through this arrangement, feeds with different particle sizes are left on the surface of the screening plate after screening, and the size of the feeds is graded. The primary screening plate 31 and the secondary screening plate 32 are fixedly connected to a connecting rod 33 on one side close to the right frame plate 12, and two U-shaped connecting rods 44 are fixedly connected to a hinge seat 45 on one side close to the left frame plate 11. One end of the connecting rod 33 is rotatably connected to the hinge seat 45. When the U-shaped connecting rod 44 is rotated, the connecting rod 33 is rotated to the hinge seat 45. When the connecting rod 44 moves up and down, the hinge seat 45 is connected with the connecting rod 33 by rotation to make one end of the primary screening plate 31 and the secondary screening plate 32 move up and down. The primary screening plate 31 and the secondary screening plate 32 are fixedly connected with the rotating shaft 34 on both sides. A plurality of rotating shaft grooves 13 are provided on the inner side of the left frame plate 11. The rotating shaft 34 is slidably arranged inside the rotating shaft groove 13. The sliding of the rotating shaft 34 in the rotating shaft groove 13 makes the middle positions of the primary screening plate 31 and the secondary screening plate 32 relatively fixed, so that the primary screening plate 31 and the secondary screening plate 32 reciprocate along the track of the rotating shaft groove 13 and swing with their respective rotating shafts 34 as the center of the circle, so that the primary screening plate 31 and the secondary screening plate 32 vibrate to screen the feed.

[0026] A funnel 39 is fixedly connected to the bottom end of the primary screening plate 31, and the center of the funnel 39 is on the same vertical line as the center of the secondary screening plate 32. When the feed falls from the funnel 39 after being screened by the primary screening plate 31, the setting of the funnel 39 can prevent the feed from splashing and bursting out of the secondary screening plate 32, causing the feed to fall on the ground and need to be cleaned manually. A U-shaped limit rod 36 is fixedly connected to the bottom end of the secondary screening plate 32, and a trough 37 is slidably provided on the inner side of the U-shaped limit rod 36. The U-shaped limit rod 36 and the trough 37 are fixed and separated by fixing bolts 38. When the feed falls from the secondary screening plate 32, it is caught by the trough 37, which is convenient for collecting feed with smaller particles. When the feed in the trough 37 is full, the fixing bolt 38 is unscrewed and the trough 37 is pulled out to clean the feed in the trough 37. The operation is simple.

[0027] The top of the primary screening plate 31 and the secondary screening plate 32 are both fixedly connected with a U-shaped baffle 35. The setting of the U-shaped baffle 35 can avoid side leakage when screening the feed. A slide groove 5 is provided on the inner side of the U-shaped baffle 35, and a connecting block 6 is slidably provided on the inner side of the slide groove 5. A brush plate 7 is fixedly connected between the two connecting blocks 6. A groove 8 is provided inside the connecting block 6, and a card block 9 is slidably provided inside the groove 8. The card block 9 passes through the top of the connecting block 6 and extends out. A spring 10 is fixedly connected to the bottom end of the card block 9. At the same time, a card groove corresponding to the card block 9 is provided on the inner side of the slide groove 5. The card block 9 is ejected by the spring 10 machine so that the card block 9 is relatively fixed in the card groove, so that the brush plate 7 is fixed on the U-shaped baffle 35. At the same time, the brush plate 7 is pushed to make the bristles clean the surfaces of the primary screening plate 31 and the secondary screening plate 32, so as to avoid the feed from adhering to the hard shell for a long time and clogging the screening hole, thereby affecting the screening of the feed.

[0028] When a grading screening machine for feed production of this embodiment is used, the user turns on the first motor 24 to rotate the spiral conveying roller 23 to transport the feed, and the transported feed falls to the upper side of the primary screening plate 31, and then turns on the second motor 42 to rotate the half gear 41, and the two tooth plates 43 are meshed with the half gear 41 to make the two tooth plates 43 move up and down reciprocatingly. At the same time, the hinge seat 45 is connected to the rotation of the connecting rod 33 to make the primary screening plate 31 and the secondary screening plate 32 move up and down. The feed is screened by the hopper 39. The feed is collected by the hopper 39 and falls onto the secondary screening plate 32. The feed is screened by the secondary screening plate 32. The screened feed falls into the trough 37. When the feed in the trough 37 is full, the trough 37 is pulled out by sliding the trough 37 and the U-shaped limit rod 36. The trough 37 can be cleaned.
