Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a novel belt protection device. Background Art

[0002] Iron objects buried in the material are difficult to find and are not easily sucked up by the iron remover. After scratching the belt in the nozzle, it will quickly split the belt into two but rarely move with the belt. Traditional anti-tear switches require iron objects to scratch the switch contactor to start, and they are not responsive and cannot provide protection in time. If the iron object is not high enough, it will not start at all.

[0003] After the tail feeding nozzle is blocked, the belt continues to run. A large amount of material that escapes is accumulated and squeezed. The escaped material is carried to the belt head by the belt return surface. If it is not discovered in time, the amount of escaped material will increase. During long-term use, it is necessary to consider that the rigid protective plate must be able to move in a straight line and in a circular shape along the belt running track together with the belt. The width of the protective plate cannot be too wide and must be divided into many narrow strip-shaped support plates fixed on the surface of the transport belt. A certain gap must be designed between the narrow strip support plates to meet the normal circulation of the belt. Due to the existence of a long gap, the belt is often damaged or the equipment is blocked.

[0004] Therefore, a novel belt protection device is proposed to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a novel belt protection device to solve the problem that the traditional tear-proof switch proposed in the above-mentioned background technology needs iron to scrape against the switch contactor before it can be started, and the reaction is not effective and cannot play a protective role in time. After the tail feeding nozzle is blocked, the belt continues to run, and a large amount of run-out material is accumulated and squeezed. The run-out material is carried to the belt head by the belt return surface. If it is not discovered in time, the amount of run-out material will increase.
