PTB-F screening type conveyor

Abstract

The invention discloses a PTB-F screening type conveyor in the technical field of conveyors. The PTB-F screening type conveyor comprises a conveyor frame, wherein the top of the conveyor frame is welded with supporting side plates in front and back in parallel, two groups of limiting sliding rods and two groups of positioning screws are respectively and longitudinally installed between the two groups of supporting side plates, the two groups of positioning screws are arranged between the two groups of limiting sliding rods, the outer ends of the positioning screws are provided with positioningmotors through couplings, and positioning sliding plates are symmetrically installed between the limiting sliding rods and the positioning screws front and back. The whole belt type transmission is designed to be sectional belt type transmission and multi-wheel interval synchronous transmission, the head part and the tail part are each provided with a section of belt transmission, the middle section is interval transmission of a liftable lifting supporting plate and a plurality of small transmission wheels which are not liftable in a matched mode, screens of different specifications can be fixed by arranging lifting mechanisms, the screens are replaced by lifting very conveniently, the equipment does not need to be stopped, and the influence on production efficiency is reduced.

Description

technical field [0001] The invention relates to the technical field of conveyors, in particular to a PTB-F screening conveyor. Background technique [0002] Conveyors have a long history. The ancient Chinese high-drum carts and water-lifting rollovers are the prototypes of modern bucket elevators and scraper conveyors. Belt conveyor is the main way of conveying bulk materials at present. The belt conveyor has the advantages of large conveying capacity, simple structure, convenient maintenance, and standardized components. It is widely used in mining, metallurgy, coal and other industries to convey loose materials or finished items. According to the requirements of the conveying process, it can be conveyed by a single , can also be composed of multiple units or combined with other conveying equipment to form a horizontal or inclined conveying system to meet the needs of different layout types of operation lines, easy to dig out powdery, granular, small pieces of low-grinding...
