Expansion scraper blade plate-type conveyer

Abstract

The invention discloses an expansion scraper blade plate-type conveyer, two ends of a frame are respectively mounted with a head pulley (7) and a tail pulley (1), a conveying chain (2) rounds the head pulley (7) and the tail pulley (1), supporting of the conveying chain (2) is located on a guide rail (4) of the frame, a lath (3) is fixed on the conveying chain (2), the expansion scraper blade is arranged on the conveying chain (2) and comprises a scraper blade (5), guide plates (9), connecting plates (13) and springs (14), a group of guide plates (9) are mounted on the conveying chain (2) at intervals, the scraper blade (5) is arranged among the guide plates (9), the connecting plates (13) are mounted at two sides of the scraper blade (5) in symmetry, at least one end of the two springs (14) is connected to the connecting plates (13), and the other end of each spring (14) is connected to the guide plates (9) and the scraper blade (5). The conveyer is used for conveying materials in bags at a large inclination angle, and is convenient to shift in a warehouse by smaller radius of gyration.

Description

technical field [0001] The invention relates to an apron conveyor, in particular to a telescopic scraper apron conveyor. Background technique [0002] Traditional fixed scraper conveyors such as figure 1 As shown, the head and tail wheels are installed on the frame, the conveyor chain is supported on the guide rail and bypasses the head and tail wheels, and the scraper and slat are fixed on the conveyor chain to form a slat conveyor as a whole. The bagged materials are placed above the slats, and the scraper pushes the bagged materials forward with the conveyor chain to realize the conveying of the bagged materials. The scraper of this scraper conveyor is not retractable. It is a fixed scraper conveyor. It has the following problems: 1. It is suitable for conveying bagged materials when the inclination angle is small. When the inclination angle of the conveyor is large, the bagged materials are easy to Rolling down along the conveyor chain, resulting in failure of conveyin...

AI Technical Summary

Problems solved by technology

The scraper of this scraper conveyor is not retractable. It is a fixed scraper conveyor. It has the following problems: 1. It is suitable for conveying bagged materials when the inclination angle is small. When the inclination angle of the conveyor is large, the bagged materials are easy to Rolling down along the conveyor chain, resulting in failure of conveying; 2. Due to the small inclination angle of the conveyor, it has a large radius of gyration, which is not easy to move in the warehouse; 3. When the height of the scraper is high, it is pressed under the bagged materials The scraper lifts up the bagged material and will break the bag of the bagged material
