Non-standard scraper conveyor, buried scraper conveyor, material conveying scraper machine. The spiral body mandrel of this machine is flexible, allowing the conveying route to be arranged along a spatial curve as needed. Depending on the length ratio of horizontal and vertical (large inclination) sections in the layout, its working principle is designed based on either a standard screw conveyor or a vertical screw conveyor. It is used in situations where the conveying route needs to be arbitrarily arranged along a spatial curve to avoid material transfer; when excessive material or hard block material enters the casing, the spiral body will float freely without causing clogging; it operates with low noise. Mainly used for simultaneously completing horizontal and vertical material conveying. For vertical conveying, the rotational speed is generally required to be high and not lower than 1000r/min.

Vertical screw conveyors are suitable for short-distance vertical conveying. The spiral of a flexible screw conveyor consists of a flexible shaft and synthetic rubber blades, which are easy to bend and can be arbitrarily arranged according to on-site or process requirements for spatial conveying. Screw conveyor blades can be either wound-type or integral drawn-type. Wound-type blades can be made to any thickness and specification size with appropriate gaps. Integral drawn-type blades are not suitable for producing non-standard spirals. Non-standard scraper conveyor, buried scraper conveyor, material conveying scraper machine.
