In the compound impurity-removing and sorting machine for crop seeds, supporting rollers are installed under the coarse-mesh drum screen and the fine-mesh drum screen.

In the compound impurity-removing and sorting machine for crop seeds, the coarse-mesh drum screen and the fine-mesh drum screen are inclined to the horizontal direction, and one end close to the feeding hopper is higher than the other end.

The above crop seed compound impurity removal and sorting machine, the feeding hopper is located at the upper right of the frame, and the outlet below the feeding hopper is connected to the coarse mesh drum screen.

The beneficial effects of the utility model:

The rotation of the motor drives the fine mesh drum sieve and the coarse mesh drum sieve to rotate together. The crop seeds and their impurities are filtered through the coarse mesh drum sieve and the fine mesh drum sieve. Small impurities are discharged through the fine miscellaneous discharge port, and crop seeds are discharged through the clean grain discharge port. When light impurities and dust pass through the clean grain discharge port, the light impurities and dust are sucked away by the dust removal device and passed through the dust removal bag. Collection; this device can remove leaves, chaff, dust and stones in crop seeds, and has the advantages of high impurity removal rate, low energy consumption, compact structure, beautiful appearance, easy and reliable operation, etc.; the screen can be customized according to user requirements It can be exchanged at will, and is widely applicable to the impurity removal operation of various kinds of crop seeds.

Detailed ways

In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings and examples.

Referring to Fig. 1, a compound impurity-removing and sorting machine for crop seeds includes a frame 3, a feed hopper 7, a discharge port, a filter device and a dust removal device, the feed hopper 7 is located at the top right of the frame 3, and the filter device includes a motor 15. The rotating shaft 4 and the trommel, the motor 15 is installed on the frame 3, and the trommel includes a coarse mesh trommel 5 installed on the frame 3 and a fine mesh trommel 6 set on the coarse mesh trommel 5. The mesh trommel 5 and the fine net trommel 6 are inclined to the horizontal direction, and one end close to the feed hopper 7 is higher than the other end, the coarse mesh trommel 5 is connected to the outlet below the feed hopper 7, and the output end of the motor 15 passes through the reducer 14, the belt The seat bearing 1 and the universal coupling 2 are connected to one end of the rotating shaft 4, and one end of the rotating shaft 4 is connected to the coarse mesh drum screen 5.
