[0026] The following will further describe the present utility model in conjunction with the appended Figures 1-5 drawings.

[0027] In order to solve the problems existing in the background art, the present application proposes the following technical solution: a rotary grading sieve for packaging in feed production.

[0028] In the specific technical solution, it includes a housing 1 and a crushing and reflux assembly 4;

[0029] As Figures 1-4 shown, a first sieve plate 2 is fixedly installed in the housing 1, and an outlet 1 is provided on the side wall above one side of the first sieve plate 2. The first sieve plate 2 can perform the first screening on the feed and can screen out the feed with larger particles. The outlet 1 can facilitate the large materials to enter the discharge cover 402; the crushing and reflux assembly 4 is installed on one side of the housing 1. The crushing and reflux assembly 4 is used for crushing the large materials. The crushing and reflux assembly 4 includes a cylinder 401 fixedly installed on one side of the housing 1, a discharge cover 402 fixedly installed on one side of the housing 1 and corresponding to the outlet 1, and a reflux pipe 403 fixedly installed on the top of the housing 1. The cylinder 401 can facilitate the loading of large materials. The discharge cover 402 can facilitate the large materials flowing out from the outlet 1 to enter the cylinder 401. The reflux pipe 403 can facilitate the large materials that have been crushed again to enter the inside of the housing 1 to be screened again. A first motor 404 is fixedly installed on the side wall of the cylinder 401. The first motor 404 can drive the hob 405 to rotate. A hob 405 is fixedly installed on the output shaft of the first motor 404 and is located inside the cylinder 401. The hob 405 can directly crush the screened large materials. A pump body 406 fixedly connected to the reflux pipe 403 is fixedly installed at the bottom of the cylinder 401. The pump body 406 can drive the crushed large materials to enter the reflux pipe 403.

[0030] The large materials screened out by the first sieve plate 2 enter the upper part inside the cylinder 401 through the outlet 1 and into the discharge cover 402. By starting the first motor 404 to drive the hob 405 to rotate, the large materials fall onto the hob 405. The hob 405 can crush the large materials. The crushed large materials fall to the bottom inside the cylinder 401. By starting the pump body 406, the pump body 406 drives the crushed large materials to enter the reflux pipe 403. The crushed materials in the reflux pipe 403 are blown by the pump body 406 into the first sieve plate 2 inside the housing 1, and the crushed materials can be screened again.

[0031] As Figure 3 and Figure 5As shown in the figure, an anti-backflow component 5 is installed inside the outer shell 1 above the first sieve plate 2. The anti-backflow component 5 is used to prevent dust from flowing back. The anti-backflow component 5 includes a dust suction pipe 501 fixedly installed on the inner wall of the outer shell 1 corresponding to the first outlet 3 and a vibration motor 502 fixedly installed on the inner top wall of the outer shell 1. The dust suction pipe 501 is communicated with the discharge cover 402 through the first outlet 3. The vibration motor 502 can vibrate the dust suction pipe 501 through the fixing ring 503. A fixing ring 503 fixedly connected to the output shaft of the vibration motor 502 is fixedly sleeved outside the dust suction pipe 501, and a filter screen 504 is fixedly installed inside. The filter screen 504 can prevent feed from entering the dust suction pipe 501.

[0032] When the pump body 406 is started, while sucking materials, the pump body 406 can drive the air in the cylinder 401 to flow towards the pump body 406. The air in the discharge cover 402 flows towards the pump body 406 through the cylinder 401. The air flow in the discharge cover 402 drives the air in the dust suction pipe 501 to move towards the pump body 406 through the first outlet 3. The air flow in the dust suction pipe 501 can drive the air in the feed inlet at the top of the outer shell 1 to enter the dust suction pipe 501 through the filter screen 504, which can prevent the dust inside the outer shell 1 from overflowing reversely through the feed inlet. The filter screen 504 can prevent feed from entering the dust suction pipe 501. At the same time, the vibration motor 502 is started to drive the fixing ring 503 to vibrate. The fixing ring 503 drives the filter screen 504 to vibrate through the dust suction pipe 501, which can vibrate off the feed adsorbed on the filter screen 504 and prevent the filter screen 504 from being blocked by feed.

[0033] As Figures 2-3 shown, a second sieve plate 6 is fixedly installed inside the outer shell 1 below the first sieve plate 2. The second sieve plate 6 can perform a second screening on the feed. An outlet two 7 and an outlet three 8 are opened on the bottom surface of the outer shell 1 below and on one side of the second sieve plate 6. The qualified feed screened out on the second sieve plate 6 falls from the outlet three 8 and can be used. The smaller feed and dust passing through the holes on the second sieve plate 6 fall into the outlet two 7 and can fall from the outlet two 7 to be collected.

[0034] As Figure 1 and Figure 3 shown, a support component 9 is installed at the bottom of the outer shell 1. The support component 9 is used to support the outer shell 1. A lifting ring 10 is fixedly installed at the top of the outer shell 1. The lifting ring 10 can connect the outer shell 1 and the lifting rope 902. The support component 9 includes a base 901 at the bottom of the outer shell 1 and a lifting rope 902 passing through the lifting ring 10. The base 901 can support the support frame 903. The lifting rope 902 can lift the lifting ring 10. A support frame 903 fixedly connected to the lifting rope 902 is welded above the base 901. The support frame 903 can stretch the lifting rope 902.

[0035] The base 901 is fixed to the ground. The base 901 can fix the support frame 903. The support frame 903 pulls the suspension rope 902. The suspension rope 902 pulls the hanging ring 10. The hanging ring 10 pulls the outer shell 1. The outer shell 1 can be suspended in the air.

[0036] As Figures 1-3 shown, a second motor 11 is fixedly installed above the base 901. A connecting rod 12 passing through the bottom of the outer shell 1 is fixedly installed on the output shaft of the second motor 11. By starting the second motor 11 to drive the connecting rod 12 to rotate, the connecting rod 12 drives the outer shell 1 to perform an eccentric motion. The outer shell 1 can perform an elliptical reciprocating motion on the horizontal plane. After the outer shell 1 shakes, it drives the first sieve plate 2 and the second sieve plate 6 to shake. The first sieve plate 2 and the second sieve plate 6 can screen the feed.
