Belt slippage detection device of grain hoister

Abstract

The invention discloses a belt slippage detection device of a grain hoister. The belt slippage detection device is arranged at the shaft end of a driven shaft of the grain bucket hoister and comprises a strong magnet, a Hall sensor, a controller, a magnet support and a sensor support. The magnet support is a right-angled member, one right-angled side of the magnet support is fixedly connected at the shaft end of the driven shaft and rotates coaxial to the driven shaft, and the strong magnet is fixedly connected onto a magnet installation plane serving as the other right-angled side. The sensor support is fixedly connected onto the outer wall of a lateral plate of the grain bucket hoister, a sensor installation hole corresponding to the strong magnet in position is arranged on the sensor support, the Hall sensor is fixedly connected onto the sensor support, corresponds to the strong magnet and is connected with the controller through a cable wire, and the Hall sensor transmits pulse signals to the controller. The belt slippage detection device of the grain hoister can timely detect the belt slippage conditions of the grain bucket hoister and timely adjust belt tightness, ensures normal operation of grain hoisting, and can be widely used on the grain bucket hoister.

Description

technical field [0001] The invention relates to a belt slip detection device, more specifically, the invention relates to a belt slip detection device applied to a grain bucket elevator of a grain circulation dryer. Background technique [0002] The grain bucket elevator used in the grain circulation dryer is used to lift the grain from a low place to a high place. The grain bucket elevator used in the grain circulation dryer on the market basically adopts a belt transmission device, and the lifting process is relatively stable. It can meet the lifting needs of a long distance, but there are deficiencies. After a period of use, the belt is loose and easy to slip. When the slip is serious, the belt pulley will run idly, and the grain will no longer be lifted. The belt transmission device of the grain bucket elevator in the prior art is built in the cylinder body, and it is impossible to know whether the belt is slipping and the severity of the slipping, so it is impossible to...

[0002] The grain bucket elevator used in the grain circulation dryer is used to lift the grain from a low place to a high place. The grain bucket elevator used in the grain circulation dryer on the market basically adopts a belt transmission device, and the lifting process is relatively stable. It can meet the lifting needs of a long distance, but there are deficiencies. After a period of use, the belt is loose and easy to slip. When the slip is serious, the belt pulley will idle and the grain will no longer be lifted.

The belt transmission device of the grain bucket elevator in the prior art is built in the barrel, and it is impossible to know whether the belt is slipping and the severity of the slipping, so it is impossible to adjust the tightness of the belt in time. case of grain lift
