[0041] One end of the linkage column 35 away from the mounting plate 31 is rotatably connected to a stabilizing block 28 , which is fixed on the base 1 . The stabilizing block 28 can support the linkage column 35 , thereby improving the stability of the linkage column 35 .

[0042] A loading block 23 is fixed to the outside of the motor 2, and the loading block 23 is fixed to the outside of the screen drum 1 2. The motor 2 can be fixed by the loading block 23, thereby improving the stability of the motor 2.

[0043] The outer sides of the sieve drum 1 2 , the sieve drum 2 3 and the sieve drum 3 4 are all hinged with movable doors, and the outer sides of the movable doors are provided with sealing rings.

[0044] Working principle: when the feed needs to be screened, the operation of motor 2 can drive the screw 16 to rotate, and the cooperation of the screw 16 and the driving sleeve 15 can drive the driving sleeve 15 and the pushing block 14 to move, and drive the linkage plate 17 to move. At this time, the displaced linkage plate 17 will drive the transmission block 22 to move, and drive the closing ring 1 20, the closing ring 2 19 and the closing plate 18 to move. When the closing plate 18 slides to the outside of the screen drum 3 4, the opening of the screen drum 3 4 is opened, and then a sufficient amount of feed is put into the inside of the screen drum 3 4. After a sufficient amount of feed is put into the inside of the screen drum 3 4, the operation of motor 2 drives the closing plate 18 to reset and move, and drives the closing plate 18 to close the opening of the screen drum 3 4. Then, Through the operation of the motor 1, the driving shaft and the driving gear 1 11 are driven to rotate, and through the cooperation of the driving gear 1 1 and the driving gear 2 12, the driving gear 2 12 and the driving column 1 9 are driven to rotate, and the screen drum 2 3 is driven to rotate. Through the rotation of the screen drum 2 3, the driving block 2 8 is driven to rotate, and the driving column 2 is driven to rotate, and the screen drum 3 4 is driven to rotate. Through the rotation of the screen drum 3 4, the feed inside the screen drum 3 4 is driven to fully contact with the sieve holes 5 on the screen drum 3 4. At this time, the feed inside the screen drum 3 4 can be initially screened through the sieve holes 5. At this time, the screened feed will enter the screen drum 2 3. Through the rotation of the screen drum 2 3, the feed inside the screen drum 2 3 is driven to fully contact with the sieve holes 5 on the screen drum 3 4. At this time, the screened feed can be screened through the sieve holes 5. The sieve holes 5 on the second cylinder 3 screen the feed inside the second cylinder 3 again. At this time, the re-screened feed will enter the inside of the sieve cylinder 1 2 through the sieve holes 5 on the second cylinder 3. At this time, the three feeds with different particle sizes will be located inside the sieve cylinder 1 2, the second cylinder 3 and the third cylinder 4 respectively. Through the operation of the hydraulic cylinder 27, the sliding block 25 can be driven to move, the rack plate 34 and the guide plate can be driven to move, the support plate 26 can be driven to deflect, the sieve cylinder 1 2 can be driven to deflect, and the sieve cylinder 2 3 and the third cylinder 4 can be driven to move. At this time, the sieve cylinder 1 2, the second cylinder 3 and the third cylinder 4 are deflected. At this time, the feed inside the sieve cylinder 2 3 and the third cylinder 4 will evenly contact the sieve holes 5 on the second cylinder 3 and the third cylinder 4, thereby improving the screening efficiency of the feed. When it needs to be discharged When the feed inside the screen drum 1 2, the screen drum 2 3 and the screen drum 3 4 is filled, the motor 2 is operated to drive the screw 16 to rotate, and the screw 16 and the drive sleeve 15 cooperate to drive the drive sleeve 15 and the push block 14 to move, and drive the linkage plate 17 to move. At this time, the displaced linkage plate 17 will drive the transmission block 22 to move, drive the closing ring 1 20, the closing ring 2 19 and the closing plate 18 to move, and the closing plate 18 will first open the opening of the screen drum 3 4. At this time, the hydraulic cylinder 27 can be used to drive the sliding block 25 to move, drive the rack plate 34 and the guide plate to move, drive the support plate 2 26 to deflect, and drive the screen drum 1 2 to deflect. When the lower horizontal end of the screen drum 2 corresponds to the receiving box 32,At this time, the hydraulic cylinder 27 stops running. At the same time, the teeth on the rack plate 34 are not in contact with the teeth of the driving gear three 36. At this time, the feed inside the screen drum three 4 will enter the corresponding receiving box 32 through the opening. When the feed inside the screen drum three 4 is discharged, the hydraulic cylinder 27 continues to run, driving the sliding block 25 to move, driving the rack plate 34 and the guide plate to move. When the teeth on the rack plate 34 are in contact with the teeth of the driving gear three 36, the displaced rack plate 34 drives the driving gear three 36 to rotate. The driving gear 36 drives the linkage column 35 to rotate, drives the mounting plate 31 to rotate, and drives the receiving box 32 on the mounting plate 31 to rotate. At this time, the receiving box 32 filled with feed inside the screen drum 34 will be misaligned with the opening of the screen drum, and the empty receiving box 32 will rotate to the bottom of the screen drum opening. Then, the motor 2 can continue to run to drive the push block 14, the linkage plate 17 and the transmission block 22 to move. Then, the displaced closed ring 2 19 will open the screen drum 23, and the feed inside the screen drum 23 will enter the new receiving box. When the feed in the screen drum 23 is exhausted, the hydraulic cylinder 27 continues to operate, driving the sliding block 25 to move, driving the rack plate 34 and the guide plate to move, and when the teeth on the rack plate 34 come into contact with the teeth of the driving gear 36, the displaced rack plate 34 drives the driving gear 36 to rotate, and the rotating driving gear 36 drives the linkage column 35 to rotate, drives the mounting plate 31 to rotate, and drives the receiving box 32 on the mounting plate 31 to rotate. At this time, the receiving box 32 filled with feed in the screen drum 23 is 2 will be misaligned with the opening of the sieve drum, and the empty receiving box 32 will rotate to the bottom of the sieve drum opening. Then, the motor 2 will continue to run, driving the push block 14, the linkage plate 17 and the transmission block 22 to move. Then, the displaced closed ring 1 20 will open the opening of the sieve drum 1 2. At this time, the feed inside the sieve drum 1 2 will enter the new receiving box 32. At this time, the feed inside the sieve drum 1 2, the sieve drum 2 3 and the sieve drum 3 4 will be collected in batches in different receiving boxes 32, thereby realizing the classified collection of feeds with different particle sizes.
