Steel ball conveyor

Abstract

The invention relates to a steel ball conveyor belonging to the technical field of conveying machinery. The steel ball conveyor comprises a conveying box, a main driving roller, a direction-changing driving roller, a group of carrier rollers, a power transmission mechanism and a steel ball carrying mechanism, wherein a wear-resisting plate is paved in a conveying cavity of the conveying box; the main driving roller is supported on the wall of the conveying box; two chain traction chain sprockets are respectively formed at the two ends of the main driving roller; the direction-changing driving roller is supported on the wall of the conveying box; chain direction-changing traction chain sprockets are respectively formed at the two ends of the direction-changing driving roller; the group of carrier rollers are supported in the middle of the conveying box; the power transmission mechanism is arranged on the top of one end of the conveying box; the steel ball carrying mechanism comprises a pair of curtain rail plate traction chains and a group of curtain rail plates, wherein the two ends of the curtain rail plates are respectively and fixedly provided with a chain buckling foot; the cross section of each curtain rail plate is in an inverted V shape; the distance between every two adjacent curtain rail plates is smaller than the diameter of a steel ball; and the carrier rollers are contacted with the curtain rail plate traction chains. The steel ball conveyor has good loading effect for the steel ball, is beneficial to unloading the steel ball, is reliable in transmission and matching, has good firmness and can guarantee good service life.

Description

technical field [0001] The invention belongs to the technical field of conveying machinery, and in particular relates to a steel ball conveyor, which is used for transporting steel balls quenched by a steel ball quenching machine to a tempering furnace for tempering. Background technique [0002] A complete steel ball production line usually includes a heating furnace for heating bars (also known as round steel) (such as Chinese patent ZL201120027307.2), a ball forming machine for rolling the bars heated by the heating furnace into steel balls ( Such as Chinese patents ZL200710023538.4Z and L201010239364.7, etc.), a quenching machine for quenching steel balls rolled by a ball forming machine (such as Chinese patents ZL200720131309.X and ZL200720131310.2, etc.) and a quenching machine for quenching A tempering furnace for tempering steel balls after quenching (such as Chinese patents ZL201010576110.4 and ZL201110029183.6, etc.). Since the medium used for quenching the steel...

AI Technical Summary

Problems solved by technology

Since the medium used for quenching the steel balls is water, the quenching pool is usually excavated on the floor as close to the ball forming machine as possible to accept and quench the steel balls formed by the ball forming machine; Since the tempering furnace is usually far away from the quenching station and is significantly higher than the floor surface, there is not only a long distance between the quenching machine and the tempering furnace, but also a large height difference between the two, so that the quenched steel There is a certain technical difficulty in introducing the ball into the tempering furnace

More specifically, the design of the steel ball conveying mechanism for conveying the quenched steel balls to the tempering furnace for tempering is relatively difficult, because the steel balls have a large mass (i.e., heavy weight), so it is difficult to use conventional conveying devices

Especially in the disclosed Chinese patent literature, there is no technical inspiration suitable for conveying steel balls
