First dish baffle of conveying roller is axially staggered to be spaced apart, the first dish baffle and phase each of on every two-stage conveying roller
On adjacent two-stage conveying roller between corresponding first dish baffle again smaller than every two-stage conveying roller of distance and two neighboring stages conveying roller it
Between gap so that space between the first dish baffle on the first dish baffle and two neighboring stages conveying roller on every two-stage conveying roller
Most short grade wood chip transfer passage can be constituted.
9. wood chip screening equipment according to claim 2, it is characterised in that: every whole grade of the end grade conveying roller group
Conveying roller main part section is hexagon, so that every whole grade conveying roller main part is hexagonal prisms, every whole grade conveying roller
Outside is provided with multiple autonomous agent partial outer faces radially raised the second dish baffle, outside each second dish baffle
Profile is made of 8 sections of arc sections outwardly protruded being distributed uniformly and circumferentially and 8 sections of arc sections being recessed inwardly, 8 sections to
The arc section of outer protrusion is located on the circumference concentric with main part, each of on every whole grade conveying roller the second dish baffle with
Distance is greater than most vice-minister grade wood chip width dimensions between adjacent second dish baffle, is less than vice-minister's grade strand length size;Every
The maximum height of the second dish baffle autonomous agent partial outer face outwardly convex is less than every whole grade each of on whole grade conveying roller
Gap between conveying roller and adjacent whole grade conveying roller, so that every whole grade conveying roller constitutes deep bid roll structure;
Multiple second dish baffles on every whole grade conveying roller are uniformly distributed along axial direction, the second dish type on odd number end grade conveying roller
Baffle is mutually shifted on axial position with the second dish baffle of corresponding position on even number end grade conveying roller, offset distance and second
2 times of dish baffle thickness are consistent, so that on odd number end grade conveying roller on the second dish baffle and even number end grade conveying roller
Space can constitute vice-minister's grade wood chip transfer passage between the second dish baffle of adjacent position.
10. wood chip screening equipment according to claim 2, it is characterised in that: every head of the chopped-off head conveying roller group
Spacing is 1~4mm between grade conveying roller and adjacent chopped-off head conveying roller;
Spacing is 5~39mm between the every two-stage conveying roller and two neighboring stages conveying roller of two-stage conveying roller group;
Spacing is 40~125mm between the every whole grade conveying roller and adjacent whole grade conveying roller of whole grade conveying roller group.
