[0008] Furthermore, the other end of the feed inlet of the drum grading screen is closed; in the direction from the feed inlet to the closed port, the aperture of the grading area on the drum grading screen becomes larger and larger.

[0009] Furthermore, at least two grading channels are arranged between the drum grading screen and the rubbing crusher.

[0010] Furthermore, there are at least three grading channels and corresponding grading areas, and a plurality of rubbing crushers are arranged below the grading channels at the middle level.

[0011] Furthermore, the rubbing and grinding crusher is connected to a multi-stage vibrating screen for screening out impurities.

[0012] Furthermore, the multi-stage vibrating screen includes a primary vibrating screen and a secondary vibrating screen, and the secondary vibrating screen is located below the primary vibrating screen.

[0013] Furthermore, a shell suction device is arranged above the multi-stage vibrating screen, and the shell suction device includes an air suction port and a fan.

[0014] Furthermore, it also includes a driving motor for changing the rotation speed of the drum grading screen.

[0015] The utility model also comprises a rubber tree seed shelling device, and the seed shelling device is adopted to shell the rubber tree seeds.

[0016] Compared with the existing technology, the beneficial effects of the utility model are:

[0017] 1. Seed shelling equipment and rubber tree seed shelling equipment are equipped with a roller for grading according to seed particle size to screen the seeds, so that the seeds are crushed by different crushers;
