[0029] 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.

[0030] Please refer to Figure 1-6 As shown, the present invention is a feed screening device for bass breeding, including a box body 1 and a screening plate 31. A cleaning mechanism 2 is arranged on the screening plate 31. The cleaning mechanism 2 includes a cleaning component and a driving component;

[0031] The cleaning component includes two slide rails 21 fixedly connected to the top surface of the screening plate 31. The inner walls of the two slide rails 21 are both slidably connected with slide blocks 22. A plurality of cleaning brushes 23 are fixedly connected to the mutually remote sides of the slide blocks 22. Racks 24 are fixedly connected to the mutually close sides of the slide blocks 22. A connecting shaft 25 is fixedly connected to the top surface of the screening plate 31. A gear 26 is rotatably connected to the outer wall of the connecting shaft 25. The gear 26 meshes with both racks 24. A connecting plate 27 is fixedly connected to the top surface of the slide block 22.

[0032] Among them, as Figure 6As shown in the figure, the driving component includes a connecting column 28 slidably connected to the inner wall of the connecting plate 27. An outer wall of the connecting column 28 is fixedly connected with a connecting rod 29. A top surface of the screening plate 31 is fixedly connected with a first U-shaped fixing plate 210. A top surface of the first U-shaped fixing plate 210 is fixedly connected with a second U-shaped fixing plate 212. An inner wall of the second U-shaped fixing plate 212 is fixedly connected with a motor 211. An output end of the motor 211 and an inner wall of the connecting rod 29 are fixedly connected.

[0033] By providing a cleaning mechanism 2, when the motor 211 on the second U-shaped fixing plate 212 and the first U-shaped fixing plate 210 is started, the connecting rod 29 rotates accordingly, and the connecting column 28 slides on the inner wall of the connecting plate 27. The connecting plate 27 drives the slider 22 to reciprocate on the slide rail 21. Since both racks 24 are engaged with the gears 26 on the connecting shaft 25, the racks 24 drive the gears 26 to rotate, and the gears 26 drive the other rack 24 to rotate. Thus, the cleaning brushes 23 on both sides will reciprocate to clean the screening plate 31. The setting of the cleaning mechanism 2 can effectively clean the blockage of the sieve holes when small feed particles block the sieve holes, so that the feed particles can pass through smoothly, greatly improving the screening efficiency of the feed.

[0034] As shown in Figure 4 the figure, a screening mechanism 3 is provided on the box body 1. The screening mechanism 3 includes a screening component and a first driving component;

[0035] The screening component includes two sleeves 32 fixedly connected to the bottom surface of the screening plate 31. Slide columns 33 are slidably connected to inner walls of the two sleeves 32. Two springs 34 are fixedly connected to the bottom surface of the screening plate 31. Bottom ends of the two springs 34 and outer walls of the two slide columns 33 are fixedly connected. Bottom ends of the two slide columns 33 are respectively hinged with a first connecting rod 35. Outer walls of the two first connecting rods 35 are respectively rotatably connected with two first connecting plates 36. Two first connecting shafts 37 and two second connecting shafts 38 are rotatably connected to the inner wall of the box body 1. Rear ends of the two first connecting shafts 37 and front sides of the two first connecting plates 36 are fixedly connected. Front ends of the two second connecting shafts 38 and rear sides of the two first connecting plates 36 are fixedly connected.

[0036] As shown in Figure 2 the figure, the first driving component includes two first belt pulleys 39 fixedly connected to rear ends of the two first connecting shafts 37. A first belt 310 is sleeved between the two first belt pulleys 39. A first motor 311 is fixedly connected to the rear side of the box body 1. An output end of the first motor 311 and a rear end of the first connecting shaft 37 are fixedly connected. An output end of the first motor 311 and an inner wall of the first belt pulley 39 are fixedly connected.

[0037] By setting up the screening mechanism 3, the first motor 311 is started. Due to the connection between the first pulley 39 and the first belt 310, the two first connecting shafts 37 will rotate. The first connecting plate 36 is fixedly connected to the first connecting shaft 37 and the second connecting shaft 38. The first connecting rod 35 in the middle of the first connecting plate 36 will also rotate. The first connecting rod 35 pushes the sliding column 33 to slide back and forth in the sleeve 32 and compresses the spring 34. When the sliding column 33 slides upward, it pushes the screening plate 31 to move upward. The high-frequency sliding of the sliding column 33 will drive the screening plate 31 to vibrate. At this time, smaller feed will fall into the collecting box 13, and larger feed will slide along the screening plate 31 to another collecting box 13. The setting of the screening mechanism 3 can make the screening plate vibrate at a high frequency. Under the action of vibration, the feed particles are evenly distributed along the surface of the screening plate and move downward. Smaller particles fall into the lower layer through the sieve holes, and larger particles are graded to a specific discharge port, which greatly improves the feed screening effect.

[0038] Among them Figure 3 As shown, a conveying mechanism 4 is provided on the box body 1, and the conveying mechanism 4 includes a second driving assembly and a conveying assembly;

[0039] The second driving assembly includes a second motor 41 fixedly connected to the top surface of the box body 1 , and a second pulley 42 is fixedly connected to the output end of the second motor 41 .

[0040] Among them Figure 3 As shown, the conveying assembly includes two support seats 43 fixedly connected to the top surface of the box body 1, the inner walls of the two support seats 43 are fixedly connected with a conveying cylinder 44, the left end and the right end of the conveying cylinder 44 are fixedly connected with a cylinder cover 45, the inner walls of the two cylinder covers 45 are rotatably connected with a third connecting shaft 46, the outer wall of the third connecting shaft 46 is fixedly connected with a spiral blade 47, the right end of the third connecting shaft 46 is fixedly connected with a second pulley 42, and a second belt 48 is sleeved between the two second pulleys 42.

[0041] By setting up a conveying mechanism 4, the feed is put into the conveying cylinder 44, the second motor 41 is started, and through the connection between the second pulley 42 and the second belt 48, the third connecting shaft 46 rotates with the spiral blade 47 in the cylinder cover 45 to transport the feed, and then the feed is evenly conveyed to the box body 1. The setting of the conveying mechanism 4 can make the feed fall evenly onto the screening plate, thereby ensuring the stability of the screening process.

[0042] Among them Figure 1 , Figure 2 and Figure 3 As shown, four support columns 11 are fixedly connected to the bottom surface of the box body 1, a box side door 12 is hinged on the right side of the box body 1, and two collection boxes 13 are slidably connected to the inner bottom wall of the box body 1.

[0043] By providing support columns 11, the support columns 11 can support the entire device, making it more stable. A collection box 13 is slidably connected to the inner bottom wall of the box body 1, which can collect the fallen feed. A box body side door 12 is hinged to the side of the box body 1, which can be conveniently opened to take out the feed, improving the convenience of feed collection.

[0044] A specific application of this embodiment is as follows: By providing a cleaning mechanism 2, when the motors 211 on the second C-shaped fixing plate 212 and the first C-shaped fixing plate 210 are started, the connecting rod 29 rotates accordingly. The connecting column 28 slides inside the inner wall of the connecting plate 27, and the connecting plate 27 drives the slider 22 to reciprocate in the slide rail 21. Since both racks 24 and the gears 26 on the connecting shaft 25 are engaged, the rack 24 drives the gear 26 to rotate, and the gear 26 drives the other rack 24 to rotate. Thus, the cleaning brushes 23 on both sides will reciprocate to clean the screening plate 31. The provision of the cleaning mechanism 2 can effectively clean the blockage of the sieve holes when small feed particles block the sieve holes, so that the feed particles can pass through smoothly, greatly improving the screening efficiency of the feed.

[0045] By providing a screening mechanism 3, when the first motor 311 is started, due to the connection of the first pulley 39 and the first belt 310, the two first connecting shafts 37 will rotate. First connecting plates 36 are fixedly connected to both the first connecting shaft 37 and the second connecting shaft 38, and the first connecting rod 35 in the middle of the first connecting plate 36 will also rotate. The first connecting rod 35 pushes the sliding column 33 to reciprocate in the sleeve 32 and compress the spring 34. When the sliding column 33 slides upward, it will push the screening plate 31 upward. The high-frequency sliding of the sliding column 33 will drive the screening plate 31 to vibrate. At this time, the smaller feed will fall into the collection box 13, and the larger feed will slide along the screening plate 31 to another collection box 13. The provision of the screening mechanism 3 can make the screening plate vibrate at a high frequency. Under the action of vibration, the feed particles are evenly distributed on the surface of the screening plate and move downward. The smaller particles pass through the sieve holes and fall to the lower layer, and the larger particles are classified to a specific discharge port, which greatly improves the screening effect of the feed.

[0046] By providing a conveying mechanism 4, the feed is placed in the conveying cylinder 44, and the second motor 41 is started. Due to the connection of the second pulley 42 and the second belt 48, the third connecting shaft 46 drives the spiral blade 47 to rotate in the cylinder cover 45 and transport the feed. Subsequently, the feed is evenly conveyed into the box body 1. The provision of the conveying mechanism 4 can make the feed evenly fall onto the screening plate, thus ensuring the stability of the screening process.

[0047] By providing support columns 11, the support columns 11 can support the entire device, making it more stable. A collection box 13 is slidably connected to the inner bottom wall of the box body 1, which can collect the fallen feed. A box body side door 12 is hinged to the side of the box body 1, which can be conveniently opened to take out the feed, improving the convenience of feed collection.
