[0065] S3, when the leveling mechanism 4 completes the leveling of the soybeans, the output shaft of two hydraulic cylinders 501 is moved up to the top dead center, and the motor 208 is started again, at this time the output shaft of the motor 208 drives the driving bevel gear 209 to rotate, so that the driven bevel gear 2010 meshing with the driving bevel gear 209 is driven to rotate, further driving the outer ring frame 205 to rotate, the pressing chamber after the soybeans are leveled is rotated to the bottom of the pressing mechanism 5 and stopped, the output shaft of two hydraulic cylinders 501 is moved down to push the pressing plate 502 to move down, so that the pressing plate 502 presses the soybean-filled pressing chamber downward to press the soybeans, and the oil in the soybeans is squeezed out, the squeezed-out oil flows into the oil groove 2011 inside through the plurality of oil filtering holes 206 at the bottom to be collected, during which the feeding mechanism 3 continuously injects soybeans into the remaining pressing chambers rotated to the bottom thereof, after the pressing is completed, the output shaft of two hydraulic cylinders 501 is moved up to move the pressing plate 502 to the top dead center, and the outer ring frame 205 is driven to rotate again by the motor 208, thereby driving the pressed soybean residue to rotate to the top of the discharge port 207, and the pressed soybean residue is discharged downward through the discharge port 207, so that the soybean oil and the soybean residue are quickly separated, and the device can continuously feed and press during the rotation of the outer ring frame 205, further improving the pressing efficiency.

[0066] In this invention, a pressing and purification device for pig feed production operates as follows: First, dried soybeans are fed into the feeding funnel 3010. The soybeans exit through the bottom of the feeding funnel 3010 and enter the intermediate rotating cylinder 309. Then, they pass through the discharge port at the bottom of the intermediate rotating cylinder 309 and the feeding port 307 into the guide trough 308, where they are fed into one of the pressing chambers. During this process, two hydraulic cylinders 501 are activated. When the output shafts of the two hydraulic cylinders 501 drive the pressing plate 502 to move downwards, they simultaneously drive the linkage block 503 to move downwards, causing the linkage rack 505 to move synchronously. This, in turn, drives the linkage gear 506 to rotate, further driving the linkage shaft 507, which is fixedly connected to the linkage gear 506, to rotate within the two rotating seats 508. The wall rotates, synchronously driving the arc gear 305 to rotate. This causes the arc gear 305 to alternately mesh with two vertically distributed straight gears 304, thereby driving the swing block 303 to swing back and forth. The swing block 303, guided by the sliding connection between the slider 302 and the two guide rails 301, moves back and forth more stably and smoothly. As the swing block 303 moves back and forth, it synchronously drives the central rotating cylinder 309 to move. The central rotating cylinder 309 has a sufficiently large opening, ensuring that it can consistently catch soybeans fed from the feeding funnel 3010 during its back-and-forth movement. The swinging motion of the central rotating cylinder 309 further distributes the soybeans more evenly into the pressing chamber, preventing them from concentrating in one place. When the pressing chamber is filled with soybeans, two hydraulic cylinders 501 are activated. The output shafts of the two hydraulic cylinders 501 drive the pressing plate 502 upward to the upper stop point. At this time, the output shaft of the motor 208 drives the active bevel gear 209 to rotate, causing the passive bevel gear 2010 meshing with the active bevel gear 209 to be driven to rotate, further driving the outer ring frame 205 to rotate, rotating one pressing chamber containing soybeans to the bottom of the leveling mechanism 4. When the output shafts of the two hydraulic cylinders 501 drive the pressing plate 502 downward, they will simultaneously drive the linkage block 503 downward, causing the linkage rack 505 to move synchronously, thereby driving the linkage gear 506 to rotate, further driving the linkage gear 506 to rotate. The linkage shaft 507 rotates on the inner wall of the two rotating seats 508, driving the two cams 406 to rotate. When the two cams 406 rotate, they push the force rod 405 downward, causing the slide rod 402 to move downward. Under the elastic reset effect of the spring 408 after the push, the slide rod 402 moves up and down reciprocally. Thus, under the connecting action of the connecting block 403, it drives the flat material arc plate 404 to move up and down synchronously. The up and down movement of the flat material arc plate 404 repeatedly flattens the soybeans in the pressing chamber filled with soybeans, flattening the top of the soybeans and preventing them from overflowing from the top of the chamber. After the flat material mechanism 4 completes the flattening of the soybeans, the output shaft of the two hydraulic cylinders 501 is started to move upward to the upper stop point, and then the motor 208 is started again.At this time, the output shaft of the motor 208 drives the driving bevel gear 209 to rotate, so that the driven bevel gear 2010 engaged with the driving bevel gear 209 is driven to rotate, further driving the outer ring frame 205 to rotate, rotating the soybean pressing chamber after being pressed to the bottom of the pressing mechanism 5 and stopping, starting the output shaft of the two hydraulic cylinders 501 to move downward, pushing the pressing plate 502 to move downward, so that the pressing plate 502 presses the soybean pressing chamber containing soybeans downward, and presses the soybeans, extruding the oil in the soybeans. The oil is collected in the oil tank 2011 through the plurality of oil filter holes 206 at the bottom. During the process, the feeding mechanism 3 continuously injects soybeans into the remaining pressing chambers located at the bottom thereof. After pressing is completed, the output shaft of the two hydraulic cylinders 501 is driven to move upward, and the pressing plate 502 is moved to the upper stop point. Then, the motor 208 drives the outer ring frame 205 to rotate again, driving the pressed soybean residue to rotate to the top of the discharge port 207, and then the soybean residue is discharged downward through the discharge port 207, so as to quickly separate the soybean oil and the soybean residue. During the rotation of the outer ring frame 205, the device can continuously feed and press, further improving the pressing efficiency.

6. The purification process of the pressing and purifying device for pig feed production according to claim 5, characterized in that: The following usage steps are included: S1. First, the dried soybeans are fed into the feeding hopper (3010). The soybeans are discharged into the intermediate rotating cylinder (309) through the bottom of the feeding hopper (3010), and then enter the guide trough (308) through the discharge port and the material distribution port (307) at the bottom of the intermediate rotating cylinder (309). They are then fed into one of the pressing chambers. During this process, two hydraulic cylinders (501) are activated. When the output shafts of the two hydraulic cylinders (501) drive the pressing plate (502) to move downward, they will simultaneously drive the linkage block (503) to move downward, causing the linkage rack (505) to move synchronously, thereby driving the linkage gear (506) to rotate. This further drives the linkage shaft (507) fixedly connected to the linkage gear (506) to rotate on the inner wall of the two rotating seats (508), so that they synchronously drive the linkage gear (506) to rotate. The rotating arc gear (305) further causes the arc gear (305) to alternately mesh with the two vertically distributed straight teeth (304), thereby driving the swing block (303) to swing back and forth. Under the sliding guidance connection of the slider (302) and the two guide rails (301), the swing block (303) moves back and forth more stably and smoothly. When the swing block (303) moves back and forth, it synchronously drives the central rotating cylinder (309) to move. The top opening of the central rotating cylinder (309) is large enough so that the central rotating cylinder (309) can always catch the soybeans fed from the feeding funnel (3010) during the back and forth movement. Furthermore, the central rotating cylinder (309) swings back and forth to feed the soybeans into the pressing chamber for more even distribution, avoiding the soybeans from accumulating in one place. S2, after the pressing chamber is filled with soybeans, two hydraulic cylinders (501) are activated. The output shafts of the two hydraulic cylinders (501) drive the pressing plate (502) to move upward to the upper stop. At this time, the output shaft of the motor (208) drives the active bevel gear (209) to rotate, so that the passive bevel gear (2010) meshing with the active bevel gear (209) is driven to rotate, further driving the outer ring frame (205) to rotate, rotating one pressing chamber containing soybeans to the bottom of the leveling mechanism (4). When the output shafts of the two hydraulic cylinders (501) drive the pressing plate (502) to move downward, they will synchronously drive the linkage block (503) to move downward, so that the linkage rack (505) moves synchronously, thereby driving the pressing plate (502) to move downward. The rotating linkage gear (506) further drives the linkage shaft (507) fixedly connected to the linkage gear (506) to rotate on the inner wall of the two rotating seats (508), and drives the two cams (406) to rotate. When the two cams (406) rotate, they push the force bar (405) downward and drive the slide bar (402) to move downward. Under the elastic reset effect of the spring (408) after the push, the slide bar (402) moves up and down repeatedly. Thus, under the connecting action of the connecting block (403), it drives the flat material arc plate (404) to move up and down synchronously. Through the up and down movement of the flat material arc plate (404), the soybeans inside the pressing chamber filled with soybeans are repeatedly flattened and the top of the soybeans is flattened to prevent the soybeans from overflowing from the top of the chamber. S3, after the leveling mechanism (4) completes the leveling of the soybeans, the output shafts of the two hydraulic cylinders (501) are started to move upward to the upper stop point, and then the motor (208) is started again. At this time, the output shaft of the motor (208) drives the active bevel gear (209) to rotate, so that the passive bevel gear (2010) meshing with the active bevel gear (209) is driven to rotate, further driving the outer ring frame (205) to rotate, rotating the soybean pressing chamber after leveling to the bottom of the pressing mechanism (5) and then stopping. The output shafts of the two hydraulic cylinders (501) are started to move downward, pushing the pressing plate (502) downward, so that the pressing plate (502) applies downward pressure to the pressing chamber containing the soybeans, pressing the soybeans and extracting the oil from the soybeans. The squeezed oil flows into the oil tank (2011) through multiple oil filter holes (206) at the bottom for collection. During this period, the feeding mechanism (3) continuously injects soybeans into the remaining pressing chambers that have rotated to the bottom. After pressing is completed, the output shafts of the two hydraulic cylinders (501) are moved upward, and the pressing plate (502) is moved to the upper stop point. Then, the outer ring frame (205) is driven to rotate again by the motor (208), and the pressed soybean residue is rotated synchronously to the top of the discharge port (207) and discharged downward through the discharge port (207), thereby quickly separating the soybean oil from the soybean residue. During the rotation of the outer ring frame (205), the device can continuously feed and press, further improving the pressing efficiency.
