Single board chain scraper conveyor extended type conveying heavy-duty scraper machine operates silently. The rotational speed of the screw body in a vertical screw conveyor is higher than that of ordinary screw conveyors. The added material, under centrifugal force, generates friction with the machine casing. This friction prevents the material from rotating with the screw blades and overcomes the gravity of the material's descent, thereby achieving vertical conveyance of the material. This machine has a small conveying capacity, low conveying height, high rotational speed, and high energy consumption. It is particularly suitable for conveying. From the perspective of material displacement direction, screw conveyors are divided into two main types: horizontal screw conveyors and vertical screw conveyors. Screw conveyors with conveying chains made of high-strength plastic are also known as food screw conveyors or screw elevators, mainly suitable for conveying large items such as cartons, turnover boxes, and bottled water. Depending on the characteristics of the conveyed material and structural differences, screw conveyors include horizontal screw conveyors, vertical screw conveyors, flexible screw conveyors, and spiral tube (roller conveyor) conveyors.

Working Principle:When the screw shaft rotates, due to the gravity of the material and the friction generated with the trough wall, the material can only move forward along the bottom of the conveyor's trough under the push of the blades, similar to a non-rotating nut moving translationally along a rotating screw. The movement of material at the intermediate bearings relies on the thrust from the material advancing from behind. Therefore, the transportation of material in the conveyor is entirely a sliding motion. To keep the screw shaft in a more favorable tension state, the driving device and discharge outlet are generally placed at the same end of the conveyor, while the feed inlet is placed as close as possible to the tail end of the other end.The rotating screw blades push the material for conveyance. The force that prevents the material from rotating with the screw conveyor blades is the material's own weight and the frictional resistance of the conveyor casing against the material. The blade surface types include solid surface, belt surface, and blade surface, depending on the material being conveyed. At the terminal end of the material movement direction, the screw shaft of the screw conveyor has thrust bearings to handle the axial reaction force from the material. For longer conveyor lengths, intermediate hanging bearings should be added.Single board chain scraper conveyor extended type conveying heavy-duty scraper machine operates silently.
