[0002] In the process of hazardous goods and solid waste treatment, the waste is generally placed in a pit, and the treatment liquid in the pit reacts with the waste. Since the waste and solid waste liquid may be dangerous, the pit door is generally equipped with an automatic sensing device. When the waste is transported to the pit, the sensing device opens the pit door and then places the waste in the pit. The electrical connection of the general sensing device is always on, and the pit may produce some dust and other foreign matter floating in the process of treatment. Since the sensing device is in a normally on state, when dust and other foreign matter fall on the sensing device, the sensing accuracy of the sensor will be reduced, resulting in the door not opening in time during the use of the equipment, thereby reducing the practicality and convenience of use of the equipment.
[0003] Based on this, the utility model designs a material pit door sensing device to solve the above problems. Utility Model Content

A wiping plate 12 is provided on the inner side of the gear ring 10, and the sensor 7 is movably connected in the wiping plate 12; it is convenient to clean the sensor 7 to prevent excessive dust and foreign matter on the sensor 7, which will cause the accuracy of the sensor 7 to decrease when it is used.
