Return trip universal adjustable combined ejector wheel device for round pipe belt conveyor

Abstract

The invention discloses a return trip universal adjustable combined ejector wheel device for a round pipe belt conveyor. The return trip universal adjustable combined ejector wheel device comprises a machine body longitudinal beam rack, hanging bracket assemblies, adjustable Haff type support assemblies, longitudinal supporting steel pipe guide rods and adjustable ejector wheel assemblies. The two hanging bracket assemblies are of a U-shaped structure and are symmetrically arranged left and right. The two adjustable Haff type support assemblies are arranged and symmetrically arranged on transverse connecting pipes in the left hanging bracket assembly and the right hanging bracket assembly. Each adjustable Haff type support assembly is composed of a transverse adjustable Haff type support, a longitudinal adjustable Haff type support and a connecting block. The three adjustable ejector wheel assemblies are arranged and are completely the same in structure. Each adjustable ejector wheel assembly is composed of a Haff connecting base, an ejector wheel, an ejector wheel installing plate, an ejector wheel connecting plate and an ejector wheel bearing block. According to the technical scheme, the structure is simple, and safety and reliability are achieved; the height, angle, supporting force and transition section shape of a return strip rubber belt in the transition process can be adjusted, and installation and adjustment are convenient; and the phenomenon of rubber belt collapsing and stacking generated in the transition process can be effectively prevented, rubber belt deviating, twisting and tearing defects are overcome, and the service life of the rubber belt is prolonged.

Description

technical field [0001] The invention relates to round tube belt conveying equipment, in particular to a return universally adjustable combined top wheel device for round tube belt conveyors. Background technique [0002] The round pipe belt conveyor is a new type of conveying equipment. The main features of this equipment are: after the material receiving section at the end of the round pipe belt conveyor, the tape gradually transitions from parallel to groove shape and deep groove shape, and then the material is wrapped and rolled into a Round tube shape; in the forming section, the tape is forcibly wrapped into a round tube by rollers arranged in a hexagonal shape, and the conveyed material is sealed in the round tube and runs stably with the tape. When it reaches the head, the tape gradually transitions, changing from a round tube shape to a deep groove shape, and finally to the head roller for unloading. The return section of the tape is the same as the running section,...

Problems solved by technology

[0003] However, the round tube belt conveyor has high requirements on the gradual flattening and grooving of the belt in the return section of the head and tail. The transition of the return journey of the traditional round tube belt conveyor is through the angle-adjustable cantilever idler rollers arranged at both ends of the belt. support, but there is no support device with corresponding structure in the middle of the return belt, especially for the belt with large bandwidth, because of its heavy belt weight, there is no intermediate support structure and only the support structure of the cantilever belt roller at both ends is used, so the transition track of the belt in the return transition section cannot be achieved. Reasonable control leads to unnatural transition of the tape, resulting in collapse and overlapping of the tape, which can easily cause the deviation of the tape, the twisting of the tape in the pipe section, and the tearing of the tape, which has caused a great impact on the user's production and economic losses.
