Technical Field

Background

The conventional conveyor is used for conveying materials, and the materials which can be conveyed can be directional or packaging bags. The conventional conveyor needs to adjust the height, front, back, left and right positions along with the change of material stacking places so as to realize material unloading at different positions.

However, the forward extension and the left-right movement of the conveyor require special driving mechanisms, and a top suspension mechanism or a ground moving mechanism is a common driving mode.
