Description

Technical Field

[0001] The invention specifically relates to the technical field of grain machinery, and in particular to a grain elevator belt anti-deviation device. Background Art

[0002] At present, the common anti-deviation switches in the industry are mostly circular in shape, and adopt the structure of a rocker arm plus a micro switch. During normal installation, the anti-deviation switch is vertically installed on both sides of the upper and lower pulleys. Once the belt deviates and hits the rocker arm, the rocker arm swings. At this time, the micro switch associated with it is under the pressure of the rocker arm and generates a stop signal.

[0003] Due to structural reasons, traditional anti-deviation switches are large in size and have limited installation locations, which make them unable to meet the monitoring application requirements for elevator belt deviation in grain machinery. In addition, the swing arm is a movable component. After being hit by the belt, it will produce relatively frequent vibration and swing. Over time, the set force will drift and the swing arm will fall off. Once the swing arm falls off and mixes into the grain machinery, it will cause serious damage to the machinery. Traditional anti-deviation switches also do not have relevant status indications and status test functions. Once the machine is installed, the working status of the anti-deviation switch itself cannot be detected. At the same time, the deviation of the pulley will not occur frequently during the entire operating cycle, so the on-site debugging of the anti-deviation switch without a status test function after installation will also cause some problems.

[0004] Therefore, it is necessary to develop a new grain elevator belt anti-deviation device to solve the above problems. Summary of the invention
