[0027] Please refer to Figures 1-5 , an embodiment provided by the present invention: An extrusion-type raw material hulling device for grain and oil processing, including a device box 1, a hulling box 6, a first sieve 10, and a connecting cylinder 33. A hulling box 6 is provided inside the top of the device box 1. Connecting cylinders 33 are provided between both sides of the hulling box 6 and the inside of the top of the device box 1.

One end of the telescopic rod 31 penetrates through the connecting cylinder 33 and is hinged to the side surface of the hulling box 6. The structure of the lateral auxiliary action composed of the telescopic rod 31, the limiting block 32, the connecting cylinder 33, the spring 34, and the connecting rod 35 enables the hulling box 6 to be stressed and perform repeated shaking actions under the elastic connection of the elastic connection member 13 when the hulling box 6 is impacted by the rotating part 4 that rotates repeatedly and when the vibrator 36 vibrates. In this way, the raw materials remaining on the inner wall of the hulling box 6 can fall better, reducing the waste of raw materials;

[0028] One side of the top of the device box 1 is connected with a support platform 8. A first rotary drive mechanism 5 is installed on the top of the support platform 8. The front side of the first rotary drive mechanism 5 is connected with a rotating part 4 through a first transmission rod 7. The top of the rotating part 4 is connected with a contact wheel 3. A vibrator 36 is installed on one side of the shelling box 6. The middle part inside the shelling box 6 is connected with a partition plate 16. The partition plate 16 divides the internal cavity of the shelling box 6 into two processing chambers 9. Guide plates 11 are connected to both sides inside the processing chamber 9. Two first sieve meshes 10 are symmetrically connected to the top of the partition plate 16. Through the setting of the two first sieve meshes 10, and the apertures of the two first sieve meshes 10 are different, but the apertures are smaller than that of the filter mesh 2. In this way, it is convenient to screen the raw materials during feeding, so that raw materials with different particle sizes enter the two processing chambers 9 for separate processing, thereby making the shelling of the raw materials more sufficient and improving the shelling efficiency;

[0029] The two first sieve meshes 10 are respectively arranged above the two processing chambers 9. The bottoms of the two processing chambers 9 are both connected with a second sieve mesh 15. The setting of the second sieve mesh 15 and the aggregate box 30 arranged below are used to collect the shelled raw materials;

[0030] Both bottoms of the two sides of the shelling box 6 are connected with the inner side of the device box 1 through elastic connectors 13;

[0031] Extrusion rollers 12 are arranged inside the shelling box 6 and inside the two processing chambers 9.

A third transmission rod 25 is connected to the inside of the first bevel gear 19. The third transmission rod 25 penetrates the placing plate 23 and is connected with a third bevel gear 26. The setting and cooperative use of the first bevel gear 19, the second bevel gear 24, the third transmission rod 25, the third bevel gear 26 and the fourth bevel gear 27 can drive the fan blade 29 to rotate to blow the raw materials passing through the second sieve mesh 15. In this way, the broken materials remaining in the raw materials can be blown away and discharged out through the sewage discharge port 14. Furthermore, the raw materials are cleaner during the later processing, ensuring the processing efficiency in the later stage;

[0034] On one side of the bottom of the third bevel gear 26, a fourth bevel gear 27 is engaged. Inside the fourth bevel gear 27, a fourth transmission rod 28 is connected. The fourth transmission rod 28 extends into the interior of the device box 1 and is connected to a fan blade 29;
