Belt slipping detecting device for gain winnowing-pan type elevator

Abstract

The invention discloses a belt slipping detecting device for a gain winnowing-pan type elevator. The belt slipping device is arranged at the side of the gain bucket type elevator, and comprises a strong magnet, a hall sensor and a controller, wherein the hall sensor is fixedly connected to a side plate of a barrel body; the strong magnet is fixed to the face of one side on a winnowing pan and opposite to the hall sensor, and the fixed connecting position is arranged at the same position at the side face of the winnowing pan, wherein the position can be sensed by the hall sensor when the strong magnet is moved near the hall sensor; and the hall sensor is connected with the controller through cables. When the belt slipping detecting device is in work, the hall sensor transmits pulse signals to the controller; if the belt slips, the pulse signals are decreased, thus an operator can know the slipping condition of the belt through the controller; if the specified number of pulses is exceeded, the operator can timely adjust the tightness of the belt, so as to make ensure that the work of gain elevating can be carried out normally; and the belt slipping detecting device can be widely applied to the gain winnowing-pan type elevator.

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. This belt transmission device A plurality of buckets are fixedly connected on the outer side of the belt, and the pulley rotates to drive the belt to move, thereby driving the bucket to move. The bucket on one side of the belt moves from bottom to top, lifting the grain from a low place to a high place, and lifting the grain from the unloading Mouth unloaded. The existing grain circulation dryer adopts belt drive, and the lifting process is relatively stable, which can meet the lifting needs of...

AI Technical Summary

Problems solved by technology

The existing grain circulation dryer adopts belt drive, and the lifting process is relatively stable, which can meet the lifting needs of a long distance, but there are deficiencies. After a period of use, the belt becomes loose and easy to slip. Elevating, a large amount of grains are accumulated in the lower part of the elevator, and material blocking occurs

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
