Through the meshing connection relationship between the bevel gear 2 52 and the bevel gear 3 55, and because the bevel gear 3 55 is fixed and does not rotate, the bevel gear 2 52 will rotate during the movement. The rotation of the bevel gear 2 52 will rotate the transmission shaft 48, and the transmission shaft 48 will drive the cam 51 to rotate, so that the cam 51 can reciprocate to push the piston plate 49, so that the piston plate 49 can be lifted and lowered, which is convenient for repeated gas injection into the injection needle tube 36. The piston plate 49 will inject gas into the injection needle tube 36 during the downward movement. When the piston plate 49 moves up, the carbon dioxide inside the box body 1 will enter the granulating cylinder 28 through the air inlet 37, effectively providing the possibility for the piston plate 49 to repeatedly inject gas into the injection needle tube 36, and then providing the possibility for continuous gas injection into the feed inside the granulating hole 13.

[0042] The cutting mechanism includes a fixed bevel gear 19 fixedly mounted on the bottom end of the granulating seat 8 and sleeved on the outside of the stirring shaft 16, a sleeve seat 20 is fixedly sleeved on the outer wall of the stirring shaft 16, a rotating shaft 21 arranged at equal distances is rotatably mounted on the outer wall of the sleeve seat 20, a bevel gear 22 meshingly connected with the fixed bevel gear 19 is sleeved on the rotating shaft 21, a rotating rod 23 is provided at one end of the rotating shaft 21, and a scraper 24 in contact with the bottom end of the granulating seat 8 is fixedly connected to the outer wall of the rotating rod 23;

[0043] The operation of the dual-axis motor 15 will drive the stirring shaft 16 to rotate, the stirring shaft 16 will drive the socket 20 to rotate, the socket 20 will drive the rotating shaft 21, the rotating rod 23 and the scraper 24 to rotate synchronously, so that the bevel gear 22 can move on the fixed helical gear 19. Through the meshing connection relationship between the bevel gear 22 and the fixed helical gear 19, the bevel gear 22 can rotate during the movement, and then the bevel gear 22 can rotate the rotating shaft 21, the rotating shaft 21 drives the rotating rod 23 to rotate, and the rotating rod 23 drives the scraper 24 to rotate, so that the scraper 24 intermittently contacts the bottom end of the granulating seat 8, so that the scraper 24 can intermittently cut the feed particles, thereby realizing the feed cutting work.

[0044] The implementation principle of the feed preparation device for mandarin fish breeding in the embodiment of the present application is as follows: the staff closes the electromagnetic valve 7 inside the through port 11 and the feeding port 3, and injects grease into the stirring seat 9 through the delivery pipe 12, and then closes the electromagnetic valve 7 in the delivery pipe 12 to make the box 1 a closed space, and then places the mixed feed material inside the feeding seat 4, and makes the feeding seat 4 discharge port on the feeding port 3, and then starts the vacuum pump 5 to extract the air inside the box 1, and then starts the carbon dioxide filling tank 6 to inject carbon dioxide into the box 1, so that the feed is in carbon dioxide during granulation, and then makes the inside of the feeding port 3 When the solenoid valve 7 is opened, the feed inside the feeding seat 4 will fall into the pelletizing seat 8 through the guide of the guide platform 44, and then the double-axis motor 15 will be started. The operation of the double-axis motor 15 will drive the fixed seat 26 to rotate, and the fixed seat 26 will drive the connecting column 27 to rotate synchronously through the stable moving part. The connecting column 27 will drive the pelletizing cylinder 28 and the guide plate 29 to slide inside the pelletizing seat 8. The connecting column 27 will contact the protrusion 62 during the rotation process. Through the structural design of the protrusion 62, the connecting column 27 will be lifted and lowered during the rotation process. The lifting of the connecting column 27 will drive the pelletizing cylinder 28 to rise and fall synchronously, so that the pelletizing cylinder 28 can be lifted;

[0045] When the granulating cylinder 28 slides on the bottom end of the granulating seat 8, the bottom end of the scraper plate 30 will be flush with the bottom end of the granulating cylinder 28, and the spring 1 33 will be in a stretched state. When the granulating cylinder 28 rises, the moving groove 32 will be driven to rise synchronously. Then, under the gravity of the scraper plate 30 and the reverse force of the spring 1 33, the scraper plate 30 will move down, so that the scraper plate 30 is in contact with the inner wall of the bottom end of the granulating seat 8. Then, during the rotation of the granulating cylinder 28, the scraper plate 30 will rotate synchronously, which is convenient for the scraper plate 30 to push the feed to move, so that the feed is continuously put into the granulating hole 13, and it is convenient for the scraper plate 30 to repeatedly extrude and granulate the feed. In the repeated extrusion process, the feed will continue to move downward to realize the discharge of the feed, and at the same time provide power for the operation of the air injection mechanism;

[0046] When the connecting column 27 is rotating and sliding on the protrusion 62 and approaching the groove 63, the granulating cylinder 28 will move downward, and the downward movement of the connecting column 27 will drive the notch 42 and the fixed gear 46 to move downward synchronously. Through the meshing of the fixed gear 46 and the toothed plate 47, and through the synchronous downward movement of the granulating cylinder 28, the injection needle 36 will be driven to move downward synchronously. Through the meshing connection relationship between the fixed gear 46 and the gear ring cylinder 45 and due to the fixing effect of the gear ring cylinder 45, the fixed gear 46 will rotate during the downward movement, and the meshing connection relationship between the toothed plate 47 and the fixed gear 46 will cause the toothed plate 47 to move downward, so that the downward movement speed of the toothed plate 47 is greater than The downward movement speed of the granulating cylinder 28, and then the tooth plate 47 will drive the pull rod 40 to move downward, the pull rod 40 will drive the air injection hole 35 to move downward, the air injection hole 35 will drive the injection needle 36 to move downward, and the injection needle 36 will pass through the through hole at the bottom end of the granulating cylinder 28. When the connecting column 27 moves to the inside of the protrusion 62, the bottom end of the granulating cylinder 28 will contact the inner wall of the bottom end of the granulating seat 8, and the injection needle 36 will be inserted into the feed inside the granulating hole 13. At the same time, when the connecting column 27 drives the granulating cylinder 28 to rotate, the movement of the granulating cylinder 28 will drive the transmission shaft 48 to move, and the transmission shaft 48 will drive the bevel gear 2 52 to rotate around the rotating shaft 43 The bevel gear 52 is meshed with the bevel gear 53 and the bevel gear 55, and the bevel gear 53 is fixed and does not rotate, so that the bevel gear 52 rotates during the movement. The rotation of the bevel gear 52 rotates the transmission shaft 48, and the transmission shaft 48 drives the cam 51 to rotate. When the outer wall long end of the cam 51 rotates downward, the cam 51 pushes the piston plate 49 to move downward, and the piston plate 49 drives the stabilizing block 61 to slide on the stabilizing rod 59, and the spring 60 generates elastic force. The downward movement of the piston plate 49 squeezes through the air inlet hole 37 into the interior of the granulating cylinder 28 and is located between the lifting plate 34 and the piston plate 4 9, inject the gas into the injection needle tube 36 through the gas injection hole 35, and then inject the gas into the feed inside the granulation hole 13 through the injection needle tube 36, and push the piston plate 49 back and forth through the cam 51, so that the piston plate 49 reciprocates and rises and falls, which is convenient for repeated gas injection into the injection needle tube 36. The piston plate 49 will inject gas into the injection needle tube 36 during the downward movement. When the piston plate 49 moves up, the carbon dioxide inside the box body 1 will enter the granulation cylinder 28 through the air inlet hole 37, effectively providing the possibility for the piston plate 49 to repeatedly inject gas into the injection needle tube 36, and then providing the possibility for continuous gas injection into the feed inside the granulation hole 13;

[0047] As the connecting column 27 continues to rotate, when the connecting column 27 contacts the upward movement of the protrusion 62, the granulating cylinder 28 will move up, and the granulating cylinder 28 will drive the injection needle tube 36 to move up synchronously. At the same time, through the action of the gear ring cylinder 45, the fixed gear 46 and the tooth plate 47, it is convenient to realize the upward movement of the tooth plate 47, and then the tooth plate 47 will drive the lifting plate 34 to move up through the pull rod 40, effectively accelerating the upward movement speed of the injection needle tube 36, so that the upward movement speed of the injection needle tube 36 is greater than the upward movement speed of the granulating cylinder 28, so that the injection needle tube 36 is accelerated to move up during the movement, and the injection needle tube 36 is prevented from touching the side wall of the granulating hole 13 during the movement and causing the damage thereof, thereby realizing the protection of the injection needle tube 36. The design effectively completes the work of injecting air into the feed inside the granulating hole 13, so that the feed can imitate the jumping of live feed when feeding, effectively improving the feed edible rate, and thus solving the problem of low feed edible rate.

[0048] The operation of the dual-axis motor 15 will drive the stirring shaft 16 to rotate, the stirring shaft 16 will drive the socket 20 to rotate, the socket 20 will drive the rotating shaft 21, the rotating rod 23 and the scraper 24 to rotate synchronously, so that the bevel gear 22 can move on the fixed helical gear 19. Through the meshing connection relationship between the bevel gear 22 and the fixed helical gear 19, the bevel gear 22 can rotate during the movement, and then the bevel gear 22 can rotate the rotating shaft 21, the rotating shaft 21 drives the rotating rod 23 to rotate, and the rotating rod 23 drives the scraper 24 to rotate, so that the scraper 24 intermittently contacts the bottom end of the granulating seat 8, so that the scraper 24 can intermittently cut the feed particles, thereby realizing the feed cutting work.

[0051] The operation of the dual-axis motor 15 will drive the connecting seat 17 to rotate, and the connecting seat 17 will drive the stirring plate 18 to rotate, so that the stirring plate 18 can move the oil and granular feed inside the stirring seat 9, so that the granular feed after granulation is fully in contact with the oil, and the oil is convenient for the oil to adhere to the outside of the feed particles. The oil can not only increase the nutritional content of the granular feed, which is beneficial to the breeding of mandarin fish, but also can achieve the sealing of the feed particles, which can prevent the discharge of carbon dioxide gas in the feed particles, effectively improve the stability of the feed particles, and provide the possibility for the granular feed to imitate the jumping of live feed when feeding.
