Detailed implementation manners

[0023] In order to further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and specific implementation manners.

[0024] Referring to Figures 1 - 6 As shown, the present invention provides: a feed screening device capable of removing feed powder residue, including a frame 1, a screening assembly 2, a vibration assembly 3 and a powder residue collection assembly 6. The vibration assembly 3 is arranged in the frame 1, the screening assembly 2 is arranged on the vibration assembly 3, and the vibration assembly 3 is used to vibrate the screening assembly 2 reciprocally to screen the feed in the screening assembly 2 layer by layer. The powder residue collection assembly 6 is arranged on one side of the frame 1 and is used to suck out and discharge the powder residue of the feed in the screening assembly 2. A feed box 4 is also arranged on the frame 1. One end of the feed box 4 vertically penetrates the frame 1 and is arranged on the top of the screening assembly 2. The feed box 4 is used to store the material to be screened. An opening and closing assembly 5 for controlling the descent of the feed is also arranged on the feed box 4. The screening assembly 2 further includes a first sieve box 21, a second sieve box 22 and a third sieve box 23. Sieve meshes with different apertures are arranged inside each sieve box to achieve multi-stage screening. This hierarchical screening design can effectively separate large particles, medium particles and fine powder residues in the feed to meet the processing requirements of different feeds. The powder residue collection assembly 6 includes a blanking device 61. A second rotation driving member 62 is fixed inside the blanking device 61 near the top through a bracket. The output end of the second rotation driving member 62 is connected with a fan blade 63. The second rotation driving member 62 is used to drive the fan blade 63 to rotate to make the air flow and suck out the powder residue in the screening assembly 2.

[0025] In this embodiment, the shunt pipe 66 is interconnected with the first sieve box 21, the second sieve box 22, and the third sieve box 23, and the shunt pipe 66 is interconnected with the feeder 61 through the second pipe 65 and the first pipe 64. After the feed vibrates up and down in the first sieve box 21, the second sieve box 22, and the third sieve box 23, by starting the second rotary drive member 62, the second rotary drive member 62 rotates the fan blade 63 at a high speed to make the air flow, and the light impurities are separated from the material by the carrying action of the air flow, improving the impurity removal effect, effectively removing the light impurities in the feed, such as feather fragments, dust, etc., and enhancing the feed cleanliness.

[0026] At the center position of the top of the feeder 61, a first pipe 64 is also fixed. One end of the first pipe 64 is connected with a second pipe 65, and a number of shunt pipes 66 are distributed on the second pipe 65. The shunt pipes 66 are respectively fixedly connected with the first sieve box 21, the second sieve box 22, and the third sieve box 23. One end of the first sieve box 21 is fixed with a first discharge port 211 for discharging the feed, one end of the second sieve box 22 is fixed with a second discharge port 221 for discharging the feed, and one end of the third sieve box 23 is fixed with a third discharge port 231 for discharging the feed.

[0027] The sieve holes at the bottom of the first sieve box 21 are larger than those at the bottom of the second sieve box 22. Mounting blocks 25 are symmetrically installed on both sides of the outside of the first sieve box 21, the second sieve box 22, and the third sieve box 23. A screw rod 26 is screwed on the mounting blocks 25 between the first sieve box 21 and the second sieve box 22 and the mounting blocks 25 between the second sieve box 22 and the third sieve box 23, and a fixing nut 27 is screwed on the screw rod 26;

[0028] On the mounting block 25, the tight connection between adjacent sieve boxes is realized by screwing in the screw rod 26 and the fixing nut 27. The screw rod 26 passes through the mounting blocks 25 between the first sieve box 21 and the second sieve box 22 and the mounting blocks 25 between the second sieve box 22 and the third sieve box 23, and then the fixing nut 27 is screwed on to tighten. This connection method is simple and effective, ensuring the firm and reliable connection between the sieve boxes, and capable of withstanding the vibration and impact force generated during the screening process.

[0029] On the front and rear sides of the third sieve box 23, connecting rods 24 are movably arranged through shafts. One end of the connecting rod 24 is movably provided with a connecting shaft 28, and the connecting shaft 28 is movably arranged on the frame 1. The vibration assembly 3 includes a connecting piece 31, a transmission rod 32, a rotating disk 33 and a bearing seat 34. The connecting piece 31 is fixed to the bottom of the third sieve box 23. The connecting piece 31 is movably connected to one end of the transmission rod 32 through a shaft. At the outer edge of the rotating disk 33, a shaft that cooperates with the other end of the transmission rod 32 is installed. The bearing seat 34 is fixed on the frame 1, and the shaft at the center of the rotating disk 33 is movably connected to the bearing seat 34. A driven wheel 35 is also installed on the shaft of the rotating disk 33. The vibration assembly 3 further includes a first rotary driving member 36. The output end of the first rotary driving member 36 is connected with a driving wheel 37. The driving wheel 37 and the driven wheel 35 are connected to each other through a belt.

[0030] The rotating disk 33 is one of the core components in the vibration assembly 3. At its outer edge, a shaft that cooperates with the other end of the transmission rod 32 is installed, enabling the transmission rod 32 to move accordingly as the rotating disk 33 rotates. At the same time, the shaft at the center of the rotating disk 33 is movably connected to the bearing seat 34 fixed on the frame 1, ensuring the stable rotation of the rotating disk 33. To drive the rotation of the rotating disk 33, the vibration assembly 3 also includes a first rotary driving member 36, a driving wheel 37 and a driven wheel 35. The first rotary driving member 36 serves as the power source, and its output end is connected with the driving wheel 37. The driving wheel 37 and the driven wheel 35 are connected to each other through a belt. When the first rotary driving member 36 is started, it drives the driving wheel 37 to rotate, and then drives the driven wheel 35 and the rotating disk 33 to rotate through the belt. Through a delicate mechanical design, the vibration assembly 3 converts the power of the first rotary driving member 36 into the reciprocating vibration of the screening assembly 2, thus realizing the efficient screening of feed. At the same time, the ingenious cooperation of the third sieve box 23 with the connecting rod 24, the connecting shaft 28 and the vibration assembly 3 further improves the screening effect and the stability of the equipment.

[0031] Working principle: When in use, pour the feed into the feed box 4. Control the feed in the feed box 4 to fall into the first sieve box 21 through the opening and closing component 5. Then, by starting the first rotary drive member 36, the first rotary drive member 36 causes the driving wheel 37 to rotate. The driving wheel 37 drives the driven wheel 35 to rotate through the belt, and then drives the rotating disc 33 to rotate. The rotating disc 33 moves the transmission rod 32, and the transmission rod 32 moves the connecting member 31, thereby causing the third sieve box 23, the second sieve box 22, and the first sieve box 21 to vibrate reciprocally. When the feed falls into the first sieve box 21, with the vibration of the first sieve box 21, the larger feed is discharged from the first discharge port 211 and collected by the staff. The smaller feed falls into the second sieve box 22 and is discharged from the second discharge port 221 and collected by the staff. The smallest feed enters the third sieve box 23 and is discharged from the third discharge port 231 and collected. When screening the feed, the feed vibrates up and down. By starting the second rotary drive member 62, the second rotary drive member 62 causes the fan blades 63 to rotate at high speed to make the air flow. The light impurities are separated from the material by the carrying action of the air flow, improving the impurity removal effect. It can effectively remove the light impurities in the feed, such as feather fragments, dust, etc., and improve the feed cleanliness. According to different requirements, by removing the screw 26, both the first sieve box 21 and the second sieve box 22 can be disassembled and removed, and the sieve boxes with different sieve holes can be replaced.

[0032] The above embodiments only represent one or several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
