Description

Technical Field

[0002] Material conveyors are very important material conveying and loading and unloading equipment, which can be widely used in mining, metallurgy, building materials, chemical industry, electric power, food processing and other industrial fields. During the long-term use of material conveyors, many safety problems may arise. For example, during the transportation of the conveyor, materials may easily fall from a height due to vibration and other reasons, or when the conveyor needs to be stopped urgently, even if the power is quickly cut off, the conveyor will continue to run for a distance due to inertia, which may easily cause casualties and material damage.

[0003] Therefore, existing material conveyors are equipped with some safety protection devices. For example, a safety protection device of a material conveyor with patent publication number CN221092431U starts the driving units at both ends of the conveying frame to drive the conveyor belt to perform conveying operations, and then starts the electric push rod at one end of the limiting guide frame, so that the L-shaped push rod as a whole performs a stable limiting sliding adjustment operation around the limiting slide groove, thereby bringing the first and second protection frames on both sides of the conveying frame surface together toward the center of the conveyor belt, thereby realizing the gathering and conveying operation of the material on the conveyor belt surface toward the center, and the conveyed material is safely protected by the blocking of the first and second protection frames.
