DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

[0021] In the mixing and stirring equipment in the document 202223280322.5, the first motor is turned on, and the first motor can drive the stirring shaft to move downward. When the stirring shaft moves into the inside of the mixing box, the second motor is turned on, and the second motor drives the stirring shaft to stir the asphalt inside the mixing box. Since the first motor drives the stirring shaft to move downward, the mixing box is fixed on the workbench. Fixing the mixing box can prevent the mixing box from moving around during the mixing process. However, when the device rotates the asphalt, it is unable to purify the exhaust gas generated by the asphalt. Through this equipment, the exhaust gas generated by the asphalt can be absorbed while the asphalt is mixed. Purifying the exhaust gas reduces the harm to the operator, and greatly improves the safety and functionality of the device.
