The specific embodiment
As Figure 1-3, the present invention by front panel 8, rear panel 3, about two side plates 5 and base plate 10 surround, top of the present invention is uncovered, base plate 10 is arcuation, base plate 10 and front panel 8, rear panel 3, about two side plates 5 identical, and about the base of two side plates 5 all connect by surface blending.
On the inwall of plate 3 and close uncovered position arranges horizontal rectangle the first reinforced rib 1 about perforation in the back.About on the outer wall of two side plates 5 and near uncovered position horizontal rectangle the second reinforced rib 4 before and after connecting is set.On the outer wall of front panel 8 and close uncovered position arranges horizontal rectangle the 3rd reinforced rib 7 about perforation.Plate 8 and extend on the outer wall of base plate 10 and be provided with many vertical the 4th reinforced ribs 9 in front, the quantity of vertical the 4th reinforced rib 9 is the odd number greater than 3, in many vertical the 4th reinforced ribs 9, have on two plane intersection lines that are arranged on side plate 5 and front panel 8 and base plate 10 with being close to side by side, namely have 4 article of the 4th reinforced rib 9 on the plane intersection line of left and right sides plate 5 and front panel 8 and base plate 10.So that position the most easy to wear, the bight of front panel 8 and left and right sides plate 5 intersections has thicker wall thickness.In many walings 9, a laterally midway location that is arranged in front panel 8 and base plate 10 is arranged.
The hypomere of plate 3 inwalls is provided with many vertically interior reinforced ribs 2 in the back, and the upper end of interior reinforced rib 2 is connected with the first reinforced rib 1, and the lower end is connected by surface blending with base plate.Many interior reinforced rib 2 is corresponding with many vertical the 4th reinforced ribs 9 of front panel 8 in horizontal spacing and position, guarantees the symmetry of stress of the present invention.
Adopt transition arc 6 to connect between the 4th reinforced rib 9 on the second reinforced rib 4 and the plane intersection line, also adopt transition arc 6 to connect between the 3rd reinforced rib 7 and the 4th reinforced rib 9, form a round and smooth coherent integral body.
Be arranged on one article of the 4th reinforced rib 9 on the laterally midway location of front panel 8 and base plate 10 injection hole 14 is set, namely injection hole 14 is arranged on front panel 8 or the base plate 10, on the front panel 8 at injection hole 14 places or the inwall of base plate 10, and the wall thickness place of process injection hole 14 arranges horizontal the 5th reinforced rib 13 about a perforation, the 5th reinforced rib 13 cross sections can be circular-arc or rectangles, the 5th reinforced rib 13 is used for strengthening the intensity at runner place, so that the present invention can guarantee rational stress relief in the course of processing.
Such as Fig. 2, the transverse horizontal length of rear panel 3 is A, is called winnowing pan length, and the transverse horizontal length of winnowing pan biside plate 5 is B, is called projection of bucket, A＞B.Vertical vertical length of rear panel 3 is C, is called winnowing pan back height, and front panel 8 oral areas are H to vertical vertical length of base plate 10, is called the front open height of winnowing pan.Wherein, C=(0.58～0.96) B, H=(0.42～0.68) B.
Front panel 8 topmosts add that the thickness behind horizontal the 3rd reinforced rib 7 is T, are called winnowing pan prosopyle thickness, B=(18～26) T.The width of the 3rd reinforced rib 7 is b, is called winnowing pan prosopyle width, B=(5～7) b.The width of the second reinforced rib 4 is b1 on the side plate 5, b1=(0.6～1) b.The width of vertical the 4th reinforced rib 9 in the middle of on front panel 8 and the base plate 10 is b2, b2=20～40mm.The width of vertical the 4th reinforced rib 9 of front panel 8 and base plate 10 top sections is b3, b3=20～50mm.The width of horizontal the first reinforced rib 1 is D, D=(C-H on the rear panel 3)+(20～40mm).Horizontal the first reinforced rib 1 is E to the width between the base plate 10 on the rear panel 3, E=(3～5) T.Angle between front panel 8 outer walls and rear panel 3 outer walls is α, is called the material casting angle, α=35 °～42 °.Rear panel 3 outer walls are β with front panel 8 end faces with the angle that rear panel 3 end face lines become, β=68 °～85 °.The angle that becomes between the bottom surface of base plate 10 and side plate 5 outer walls is γ, is called the suit angle, γ=94 °～100 °.Side plate 5 is T1 with the gross thickness of reinforced rib 4, T1=(0.83～1.11) T.The gross thickness of rear panel 3 and the first reinforced rib 1 is T2, T2=(0.93～1.0) T.The thickness of rear panel 3, front panel 8 and base plate 10 all is T3, T3=(0.4～0.56) T.The second reinforced rib 4 is R at the arc transition radius with vertical the 4th reinforced rib of front panel 8 and base plate 10 top sections 9 intersections on the side plate 5, and namely the arc transition radius at transition arc 6 places is R, R=(0.8～2.5) b.
Existing winnowing pan and the present invention are tested simultaneously, during test, existing winnowing pan is installed on the identical bucket elevator with the present invention, bucket elevator adopts identical tractive force, existing winnowing pan is operated under the identical working condition with the present invention, the result is, overload capacity of the present invention is twice than existing winnowing pan, stressed strength increase 80%, existing winnowing pan work had disrepair phenomenon after 2 years, work of the present invention just had identical disrepair phenomenon in nearly 4 years, illustrated to have improved 1.8-2 service life of the present invention doubly.
