Specific implementation mode
As shown in attached drawing 1,2, the feed box of the utility model includes hopper 1 for being connected with 7 discharge end of screen box, sets
It sets the selection by winnowing channel 2 on the left of hopper 1 and the first discharge port 3 and the second discharge port 4 in 1 front side of hopper is set；Described
Demarcation strip is provided in hopper 1, hopper 1 is separated into first passage 12, second channel 5, third channel 13 and by demarcation strip
Four-way 6, the second channel 5, fourth lane 6 are connected with selection by winnowing channel 2, the first passage 12 and the first discharge port 3
It is connected, the third channel 13 is connected with the second discharge port 4.The upper end in the selection by winnowing channel 2 is connected with pneumatic separation device,
Lower end is corresponding with proportion platform.By being provided with the feed box of selection by winnowing in the discharge end of screen box 7, high efficiency air can be effectively realized
Choosing solves the problems, such as that finished product when big yield processing by screening still contains dust, and finished product when ensure that big yield is net
Degree.Material after screening can enter selection by winnowing channel by second channel 5 and fourth lane 6 respectively and carry out selection by winnowing, by thicker grain
Layer is divided into two relatively thin grain layers, and air-flow is easier to penetrate grain layer when selection by winnowing, it is ensured that selection by winnowing effect when big yield processing.Simultaneously
It can increase the distance between second channel 5, fourth lane 6 and selection by winnowing channel bottom end, increase drop when material wind selection, it can be with
Further ensure that efficient selection by winnowing.
As shown in attached drawing 3,4, the front end of the hopper 1 is provided with screen box 7, screening is collectively formed with feed box in screen box 7
Device is provided with four layers of sieve in screen box 7, from top to bottom respectively the first sieve, the second sieve, third sieve and
