[0032] The dust-proof component includes a dust-proof main body 2. The outer contour shape of the dust-proof main body 2 matches the inner contour shape of the exhaust hole 131 of the tank truck 13. For example, if the exhaust hole 131 of the tank truck 13 is a round hole, the dust-proof main body 2 is cylindrical; if the exhaust hole 131 of the tank truck 13 is a square hole, the dust-proof main body 2 is a cube. The dust-proof main body 2 has an accommodation space that penetrates the upper and lower ends of the dust-proof main body 2.

[0033] The filter screen 3 is arranged in the accommodation space of the dust-proof main body 2, or the filter screen 3 is arranged at one end of the dust-proof main body 2 (such as the top end or the bottom end). The filter screen 3 closes this end. The plane where the filter screen 3 is located is parallel and abuts against one end face of the dust-proof main body 2. The outer diameter of the filter screen 3 is equal to the outer diameter of the dust-proof main body 2, or the outer diameter of the filter screen 3 is slightly smaller than the outer diameter of the dust-proof main body 2, or the outer diameter of the filter screen 3 is slightly larger than the outer diameter of the dust-proof main body 2. Filter holes are formed in the filter screen 3, and the filter holes communicate with the accommodation space.

[0034] The lifting member 1 is connected to the dust-proof member and is used to drive the dust-proof member into the exhaust hole 131 of the tank truck 13 and move the dust-proof member out of the exhaust hole 131 of the tank truck 13. The height of the dust-proof plug is adjusted through the lifting member 1 so that the dust-proof member is closely fitted with the exhaust hole 131 at the tail of the tank truck 13; the material level sensor 4 is connected to the dust-proof member, and the material level sensor 4 is used to detect the material level in the tank truck 13 when the device is in the working state.
