The utility model provides a pinning and
cutting device for building block shading
processing, which relates to the technical field of building block
processing and comprises a
protection mechanism, a
processing mechanism is fixedly mounted at the bottom of the inner wall of the
protection mechanism, and the processing mechanism comprises a shell. According to the
waste gas treatment device, under the cooperation of the
protection mechanism and the treatment mechanism, the protection cover can prevent chippings or
waste gas generated in work from diffusing everywhere, polluting the environment and
scratching the
skin of workers, after the
waste gas treatment device is started, pollutants such as dust and chippings can be driven into the collection box to be collected in a unified mode, the workers can recycle or destroy the pollutants conveniently, and the working efficiency is improved. The production cost is reduced, the cleaning work of workers is reduced, the waste gas is discharged after being treated, the situation that the waste gas is directly discharged to pollute the environment can be avoided, the air quality and the
ecological environment can be protected, the concentration of harmful substances in a working place is reduced, the workers are prevented from inhaling harmful gas, and the body health of the workers is protected.
