Abstract
The utility model relates to a tearing automatic protecting device for a belt conveying powdery and granular material. A micro switch (6) is closed by the action of a tension spring (5) around a supporting point (4) by a lever (7) through a material receiving plate (3), and thereby, a control circuit is triggered so that the operation of the belt is stopped, playing a protecting function. The driving mechanism of the original belt does not need to be changed by the utility model. The utility model has the advantage of good protecting effect.
Description
The utility model relates to a kind of belt conveyor fender guard.
It is a great problem in the current domestic and international commercial production that belt conveyor is torn; at present existing various forms of belt protection devices; as CN89211475.4 disclosed " protecting longitudinal rupture of adhesive tape device "; but these protectors are for the belt of conveying granular material; because it is stuck in material-falling hopper metal objects such as iron nail, rake teeth to occur in the convey materials; belt is pierced when tearing, and does not just have due protective effect.
The purpose of this utility model is to provide a kind of belt tearing automatic safety device of carrying powder and granular material.
Fender guard of the present utility model by the plate that connects material (3), relies on the action around fulcrum (4) of lever (7), extension spring (5), makes micro-switch (6) closure, and trigger control circuit reaches protective effect.The end of plate (3) of connecting material connects lever (7), and the end joint connection extension spring (5) of lever (7) is connected micro-switch (6) between balance pivot (4) and the plate that connects material (3).
The plate (3) that connects material is to be made of mesh plate.
When belt is pierced through by metal object and tears; belt tearing mouth place will have big content of starting materials to fall on the plate that connects material (3); this mesh plate that connects material just can rely on lever (7) and extension spring (5) and moves around fulcrum (4); make micro-switch (6) closure; trigger control circuit; belt is suddenly stopped, and the length that belt is torn is controlled in the shortest scope, reaches the effect of protection belt.
Belt tearing fender guard provided by the utility model does not need to change the original structure of belt transportation, can play a protective role for the particularly conveying powdered colyliform belt tearing of belt conveyor.
