When the first material level detection device is triggered by the material and the second material level detection device is not triggered by the material, the material level of the material in the hopper 42 is low, and at the moment, the possibility of overflowing does not exist, so that the feeding speed can be increased, and the feeding device can be controlled to feed by adopting the first feeding speed.
For example, the reference feeding speed may be preset to be 50 square/hour, and the first feeding speed may be increased by 5% compared to the reference feeding speed, and may be 52.5 square/hour.
When the first level detection device is triggered by the material, the second level detection device is triggered by the material, and the third level detection device is not triggered by the material, it is indicated that the level of the material in the hopper 42 may exceed the midpoint position of the hopper 42 in the vertical direction, and at this time, if the feeding speed is high, the possibility of overflow may exist, so that the feeding speed needs to be reduced, the feeding device may be controlled to feed at the second feeding speed, which may be reduced by 5% compared to the reference feeding speed and may be 47.5 square/hour.
When the first material level detection device, the second material level detection device and the third material level detection device are triggered by the material, it is indicated that the material level of the material in the hopper 42 reaches the maximum height value in the vertical direction, if the material is continuously fed, the risk of overflow is likely to occur, at this time, the feeding device is controlled to stop feeding until the pumping equipment 41 pumps part of the material in the hopper 42, and then the material is continuously fed according to the feeding speed corresponding to the triggered condition of the material level detection device 50.
