[0047] A rotating blade 501 is rotatably connected to the top of the separation box 1, and a feed port is provided on the top surface of the box cover 2. The rotating blade 501 is cross-shaped, and one end of the rotating blade 501 is at the bottom of the feed port, which is convenient for pushing the rotating blade 501 to rotate. A first belt connecting mechanism 502 is fixedly connected to one end of the rotating blade 501, and a transmission mechanism 505 is fixedly connected to the bottom end of the first belt connecting mechanism 502. The transmission mechanism 505 includes a connecting shaft and a bevel gear connecting mechanism.

The bevel gear connecting mechanism is fixed to a cleaning brush 504, and the cleaning brush 504 is rotatably connected to the inside of the separation box 1, which is convenient for driving the cleaning brush 504 to rotate and ensure the stability of the rotation of the cleaning brush 504. The top surface of the cleaning brush 504 contacts the bottom surface of the separation net 3, which is convenient for cleaning the separation net 3. The cleaning brush 504 is rotatably connected to the top of one end of the transmission mechanism 505;

[0048] The bottom end of the first belt connection mechanism 502 is fixedly connected to the second belt connection mechanism 506, and the second belt connection mechanism 506 includes three pulleys and two belts. The bottom end of the first belt connection mechanism 502, the end of the cam 503 and the outer end of the separation box 1 are all provided with pulleys, and two adjacent pulleys are connected by pulleys. The outer side of the cam 503 contacts the bottom of the collection frame 510, which can make the collection frame 510 vibrate, so that the impurities inside the collection frame 510 are more compact. The second belt connection mechanism 506 is fixedly connected to the cam 503 at one end. 03. A placing frame 507 is slidably connected inside the separation box 1. A plurality of spring dampers 508 are installed inside the placing frame 507 by screws. A placing frame 509 is installed on the top of the spring damper 508 by screws. The placing frame 507 includes three mounting plates and four connecting rods. The bottom ends of two adjacent mounting plates are fixedly connected by two connecting rods to facilitate the placement of two collecting frames 510. A rubber frame is bonded to the outside of the mounting plate. The length of the collecting frame 510 is equal to the spacing between the two adjacent mounting plates. A collecting frame 510 is placed between the two placing frames 509.

[0049] A limiting member 511 is installed on the top of the box cover 2, and the limiting member 511 includes an adjusting threaded cylinder 5111, an adjusting screw rod 5112 and a limiting frame 5113;

[0050] One end of the top of the box cover 2 is rotatably connected to an adjusting threaded barrel 5111, and the inside of the adjusting threaded barrel 5111 is threadedly connected to an adjusting screw 5112. A limiting frame 5113 is installed on the top of the adjusting screw 5112 through a screw. One end face of the limiting frame 5113 is in contact with the outer side of the separation box 1 to ensure the stability of the movement of the limiting frame 5113 and facilitate the limitation of the end of the placement frame 507, thereby facilitating the installation of the placement frame 507.

[0051] The personnel put the collecting frame 510 between the two placing frames 509, and then move the placing frame 507 into the separation box 1. The personnel rotate the adjusting threaded cylinder 5111 to drive the adjusting screw 5112 and the limiting frame 5113 to move, and limit the two ends of the placing frame 507 through the limiting frame 5113 to place the collecting frame 510 in the separation box 1, and then pass the food raw materials into the separation box 1 from the feeding port. With the impact of the raw materials, the rotating blade 501 is driven to rotate, and the cleaning brush 504 is rotated through the connection of the first belt connecting mechanism 502 and the transmission mechanism 505 to realize the cleaning of the bottom of the separation net 3, thereby accelerating the efficiency and effect of the separation of the raw materials by the separation net 3. At the same time, the cam 503 is driven to rotate through the connection of the second belt connecting mechanism 506. At this time, the cam 503 is constantly in contact with the collecting frame 510. Through the use of the spring damper 508, the collecting frame 510 vibrates, thereby making the solid raw materials inside the collecting frame 510 more compact, so that more solid raw materials can be collected inside the collecting frame 510.

[0052] As the solid-liquid separation of the raw materials occurs, solid impurities will accumulate on the top of the separation net 3, causing the separation net 3 to be gradually blocked. During the raw material separation process, the amount of material fed into the separation box 1 is constant, causing the raw materials inside the separation box 1 to gradually accumulate. As the raw materials gradually accumulate, the liquid will drive the float 4161 to move upward, and the movement of the float 4161 will drive the moving column 4162 to move. When the moving column 4162 contacts the induction switch 4163, the drive motor 401 is turned on, driving the drive screw 402 to rotate, and the rotation of the drive screw 402 drives the moving plate 403 to move, pushing the impurities on the top of the separation net 3 to move. The movement of the moving plate 403 will drive the blocking plate 404 to move, blocking the top of the separation net 3 that has been cleaned, which makes it difficult for the moving plate 403 to be reset. When the moving plate 403 moves, it will drive the pushing plate to move, and the movement of the pushing plate drives the closing plate 406 to rotate, so that the reset spring 407 is compressed, and the bottom of the guide plate 405 is opened, and the solid raw material is pushed into the collection frame 510 to reset the solid raw material. When pushing the solid raw material, the blocking plate 404 moves and drives the connecting rope 409 to move, and the movement of the connecting rope 409 makes the compression plate 410 move, so that the compression plate 410 and the magnetic strip 411 are adsorbed on each other.

[0053] After the solid raw materials are pushed into the collecting frame 510, the moving plate 403 and the blocking plate 404 move in opposite directions. As the blocking plate 404 moves, the driving rod 415 is pushed to move, so that the end of the driving rod 415 drives the pushing rod 413 to move, so that the pushing rod 413 moves downward, pushing the compression plate 410 to move, so that the compression plate 410 is separated from the magnetic strip 411. When the magnetic strip 411 is separated from the compression plate 410, the compression plate 410 quickly falls into the collecting frame 510 due to gravity, thereby achieving the solid impurities in the collecting frame 510. The solid-liquid separation effect is improved by pressing the solid raw material. When the solid raw material is not collected, the compression plate 410 is always on the top of the solid raw material, and can continuously press the solid raw material to further improve the solid-liquid separation effect. When the pushing plate is not in contact with the closing plate 406, the reset spring 407 is reset to push the closing plate 406 to rotate, and the end of the guide plate 405 is closed to facilitate the subsequent solid-liquid separation of the raw material. At this time, the float 4161 moves downward with the solid-liquid separation, which is convenient for the next cleaning of the top of the separation net 3, without manual cleaning by personnel, reducing the labor intensity of personnel;

[0054] When there are a lot of solid raw materials collected in the collecting frame 510, the personnel rotate and adjust the threaded barrel 5111 to move the limit frame 5113 upward so that the limit frame 5113 does not contact the placing rack 507. Then, the personnel move the empty collecting frame 510 to the inside of the separation box 1 by moving the placing rack 507. At this time, the collecting frame 510 containing the solid raw materials is moved out of the separation box 1. The personnel cleans the placing rack 507 by taking the collecting frame 510 out of the placing rack 507. After taking the collecting frame 510 out of the placing rack 507, the personnel rotate and adjust the threaded barrel 5111 again to make the limit frame 5113 contact with the placing rack 507, so that the placing rack 507 can be fixed, thereby realizing continuous separation of raw materials and improving the efficiency of solid-liquid separation.
