Abstract

A steel belt conveying apparatus includes upper and lower horizontal conveying portions, left and right inclined conveying chains, a connecting rod frame, an inclined frame, a drive portion, and a height adjustment cylinder. The left inclined conveying chain is separately connected to the upper and lower horizontal conveying portions. The right inclined conveying chain is separately connected to the upper and lower horizontal conveying portions. A top portion of the connecting rod frame is hingedly connected to an upper horizontal frame of the upper horizontal conveying portion. A bottom portion is hingedly connected to a lower frame of the lower horizontal conveying portion. A top portion of the inclined frame is hingedly connected to an upper horizontal drive shaft of the upper horizontal conveying portion, and a bottom portion is hingedly connected to a lower horizontal drive shaft of the lower horizontal conveying portion.
