Taper tube series
The conical tube is the basic grain unloading unit of the flexible duct hose. While two adjacent conical tubes can be close or loose from each other.
Hose support ring
In order to support the fabric duct hose, a certain number of iron rings are on each section of conical pipe. The support ring has 2 kinds, an outer ring and an inner ring. The ring inside the hose is the inner ring. While the ring outside the hose is the outer ring.
Flexible support connection system between tapered pipe and ring
We need to make telescopic movement between the tapered tubes and the rings. Thus there must be a flexible system that restricts and connects them to each other. Then it can form a relatively independent system to support all the air duct hose.
Cloth flexible duct hose
The outer surface of the duct hose is a cloth hose. Then it wraps the tapered pipe and the support ring. The cloth tube can be stretched, forming an external flexible system like the internal flexible system. The fabric duct is air-tight. Thus it can prevent the outside air enters. It can also prevent the internal dust from flying. Besides, it forms an annular space with the cone tube to ensure the smooth flow of suction air.
The air duct hose suction system has two forms. One without dust collector and fan. While the other one with dust collector and fan. The air vent hose without dust collector and fan relies on the surrounding wind net for suction. Thus is suitable for fixed telescopic hose. While the other one can work independently and is suitable for mobile flexible hose ducting. But the volume is relatively large.
