[0002] The sand and gravel sorting device is a kind of equipment specially used to sort and classify sand and gravel according to different specifications and characteristics.

[0003] At present, in the prior art, for example, a Chinese patent with announcement number CN216880262U discloses a continuous sorting device for construction sand and gravel. The device combines a conical screen with a feed distributor. The feed distributor rotates to pour sand and gravel at different positions of the conical screen, thereby avoiding the problem of accumulation of sand and gravel feed in the prior art, and effectively increasing the sorting efficiency of the continuous sorting device for construction sand and gravel. However, when the feed distributor in the device rotates, a centrifugal force is applied to the sand and gravel, which easily causes some sand and gravel to fly out of the area of ​​the conical screen, thereby causing some sand and gravel to be unable to be screened, thereby affecting the effect of sand and gravel. In view of this, we propose a construction sand and gravel sorting device. Utility Model Content
