[0023] In this embodiment, the bulk grain quantity monitoring equipment is a monitoring device that slides along the hanging rail 1 to a specified position, or a detection device that is fixedly installed at a specified position. After the bulk grain quantity is monitored, the electric push rod 5 is started to drive the rotation support 19 to rotate and drive the auxiliary cylinder 4 to rotate towards the bottom of the sliding seat 2, so as to protect the lens 13 and reduce the dust falling. At the same time, the dust removal ring 12 is provided. When the electric push rod 5 drives the auxiliary cylinder 4 to overturn upwards, the connecting rod 21 and the push-pull plate 16 pull the air bag 10 to store air. When the electric push rod 5 drives the auxiliary cylinder 4 to overturn downwards to the working position, the connecting rod 21 and the push-pull plate 16 are driven to move backward to compress the air bag 10. The gas in the air bag 10 is transported to the inside of the dust removal ring 12 through the air pipe 8 and then blown out through the air blowing holes 14. The gas is used to clean the dust attached to the lens 13, so as to reduce the influence of dust accumulation on the monitoring device.
