In the process of conveying of belt bucket elevator, due to the action of materials, the conveyor belt tends to run off, in serious case, it will be stuck, which affects agricultural production and reduces efficiency. In order to solve the above problems, the technical scheme adopted by the utility model is anti-deviation device of belt chain bucket elevator. It includes a housing, a group of wheels arranged in the housing and a conveyor belt installed on the group of wheels. The inner sides of the housing are also provided with an automatic rectifying device and an alarm switch for the deviation of the conveyor belt. The alarm switch is mounted on the upper part of the arc groove and is photoelectric proximity switch.Besides the photoelectric proximity switch is connected with the control system of the conveyor belt. Compared with the existing technology, the beneficial effect of the utility model is as follows: the utility model can automatically correct the deviation of the conveyor by setting an automatic rectifying device and an alarm switch can be sent to alarm the serious deviation of the conveyor belt to remind the staff.
Specific mode of implementation

The utility mode provide a belt hoist anti-running deviation device, including a housing, a group of wheels arranged in the housing and a conveyor belt installed on the group of wheels of belt bucket elevator. The inner sides of the housing are also equipped with automatic rectifying device for the deviation of the conveyor belt and the automatic deviation correction device is also equipped with an alarm switch for the conveyor belt deviation alarm. When the conveyor belt runs off track, it runs off track along the arc-shaped groove and the surface is smooth. Due to the action of gravity in the arc-shaped groove, the conveyor belt will be automatically slide to the normal position, and the deviation will be corrected automatically. The inner side of the installation block of the automatic rectifying device in the utility mode can also be divided into a lower narrow inclined surface and a upper wide inclined surface. In other words, when the conveyor belt ruins off track, it will automatically returns to the normal state due to being squeeze by the inclined surface. The alarm switch is photoelectric proximity switch and connected with the control system of the belt elevator. It can be set that when the photoelectric proximity switch detects the conveyor belt fails automatically correct deviation within a fixed period of time, an alarm can be sent through the control system to remind the staff.
On the one hand, the utility mode can automatically correct the deviation of the conveyor belt by setting an automatic rectifying device, and at the same time, an alarm switch is set to alarm the serious deviation of belt bucket elevator to remind the staff.
