Title:
SPIRAL CONVEYING NET CHAIN
Document Type and Number:
WIPO Patent Application WO/2019/015201
Kind Code:
A1
Abstract:
Disclosed is a spiral conveying net chain (1), relating to the field of conveying apparatuses. The spiral conveying net chain comprises a conveying net chain body, wherein driven teeth (3, 6, 8, 10, 12) are arranged at inner edges of the conveying net chain body, and the driven teeth (3, 6, 8, 10, 12) are used for engaging with driving teeth (4, 5, 7, 9, 11) at an outer periphery of a rotating drum for driving the conveying net chain body to rotate; and contact faces between the driven teeth (3, 6, 8, 10, 12) and the driving teeth (4, 5, 7, 9, 11) are one of bevel faces, arc-shaped faces, V-shaped contact faces and T-shaped contact faces, so that the force-bearing direction between the driven teeth (3, 6, 8, 10, 12) and the driving teeth (4, 5, 7, 9, 11) is shifted inwards relative to a rotation direction of the conveying net chain body. When the swaddling force applied by the spiral conveying net chain (1) on the rotating drum (2) is relatively small, the spiral conveying net chain (1) cannot separate or slide away from the driving teeth (4, 5, 7, 9, 11) of the rotating drum (2) and the driven teeth (3, 6, 8, 10, 12), and the spiral conveying net chain (1) is capable of continuously rotating along with the rotating drum (2).
