Description

A kind of winnowing pan of bucket elevator

Technical field

The present invention relates to a kind of bucket elevator, be specifically related to the winnowing pan of bucket elevator, the powdery of loose thickness, lump material granular, little are carried.

Background technology

Winnowing pan is one of key fitment of bucket elevator, typically via traction belt and chain as driving member, the loose powdery of density��2.2t/m3, lump material granular, little is carried out continuance lifting conveying.

The plastics winnowing pan that the winnowing pan macromolecular material that bucket elevator is conventional is made, the wall thickness design at the existing each position of plastics winnowing pan is unreasonable, and in use, position easy to wear can premature abrasion. In order to increase intensity, some winnowing pan suitably thickeies wall thickness at oral area, some winnowing pan designs reinforcement at outer wall, quantity and the Position Design of reinforcement are unreasonable, all do not account for situation when winnowing pan is hit, owing to the winnowing pan maximum position that is hit is the junction of front panel and side panel, and time actually used, only having a reinforcement in this junction is inadequate, local pressure disrepair phenomenon often occurs, affects its service life.

Summary of the invention

The technical problem to be solved is to provide the plastics winnowing pan of the bucket elevator of a kind of rational in infrastructure, long service life.

The technical solution used in the present invention is: winnowing pan of the present invention is surrounded by rear board, front panel, two, left and right side panel and base plate, and base plate is arcuation, and top is uncovered, and the top of rear board inwall arranges laterally the first reinforcement that the cross section running through left and right is rectangle; Top on the outer wall of two side panels in left and right is respectively provided with laterally the second reinforcement that the cross section before and after running through is rectangle, and the end face of two side panels and the end face of the second reinforcement are mutually neat; Top on the outer wall of front panel arranges laterally the 3rd reinforcement that the cross section running through left and right is triangle, and the end face of the 3rd reinforcement is mutually neat with the end face of front panel; Extend on the outer wall of front panel and from the bottom surface of the 3rd reinforcement and the outer surface of base plate is provided with a plurality of longitudinal direction the 4th reinforcement;The quantity of the 4th reinforcement is the odd number more than 3, is respectively provided with two articles of the 4th reinforcements being closely packed together on left and right sides panel has a common boundary with the plane of front panel, base plate respectively; Connect with transition arc between second reinforcement and the 4th reinforcement; The transition brace rod that cross section is triangle is connected between 3rd reinforcement and the 4th reinforcement.

The transverse horizontal length of two side panels is B, rear board end face is C to the longitudinally perpendicular height between base plate, front panel end face is H to the longitudinally perpendicular height between base plate, front panel is T plus the gross thickness after the 3rd reinforcement, the gross thickness of side panel and the second reinforcement is T1, the gross thickness of rear board and the first reinforcement is T2, rear board, front panel, the thickness of base plate is T3, the width of the 3rd reinforcement is b, the end face of the 3rd reinforcement is b1 to the width of the 3rd the most front thickest point of reinforcement, the end face of the 3rd reinforcement is b2 to the width at transition brace rod bottommost place, the width of the second reinforcement on side panel and rear board intersection is b3, the width of the first reinforcement on rear board inwall is D, first reinforcement bottom surface is E to the width of rear board and base plate transition position, the width of the 4th reinforcement is F, distance between two spaced reinforcements is G, between front panel inwall and rear board outer wall, angle is ��, between lateral surface and the rear board end face of the second reinforcement, angle is ��, between side panel inwall and rear board end face, formed angle is ��, B=(0.9��1.1) C, H=(0.63��0.74) B, T=(0.03��0.05) B, T1=(0.8��1.1) T, T2=(0.8��1.1) T, T3=(0.4��0.6) T, E=(3��5) T, b=(0.125��0.25) B, b1=(0.6��0.8) b, b2=(1.5��1.8) b, b3=(0.4��0.8) b, D=(C-H)+(20��40mm), F=20��45mm, G=40��110mm, ��=35 �㡫42 ��, ��=86 �㡫92 ��, ��=80 �㡫85 ��.

The solution have the advantages that: the present invention arranges the reinforcement of sufficient intensity in the winnowing pan maximum edge that is hit, and arranges transition brace rod, it is to avoid local pressure is damaged on waling with cross reinforcing. Due to the fact that the rational reinforcement of employing is arranged and rational size design, make the present invention can adopt relatively thin wall thickness in the remaining panel part except reinforcement, so, while not increasing material consumption, strengthened in uncovered and the position that is hit intensity and supplemented. Through actual tests, under same work working condition, the present invention is compared with existing product, overload capacity doubles, and is increased by 80% by force intensity, substantially prolongs the wearing-in period of damageable zone, improve the service life of whole winnowing pan, service life improves about 1.8-2 times.
