Description

Technical Field

[0001] The invention relates to the technical field of ground burning machines, and in particular to a blower for a ground burning machine. Background Art

[0002] A ground burning machine generally uses the combustion of high-temperature and high-pressure gas to generate flames. A ground burning machine generally includes components such as an engine, a traveling mechanism, a combustion chamber, and a gas source. Existing small ground burning machines are mainly used for the treatment of oil-soaked concrete floors, road signs, various wet / humid surface drying treatments, and the treatment of highway and bridge joints.

[0003] Since the ground burning machine needs to mix the gas source and air and fully burn them in the burner, and the general blower has a small blowing volume and cannot supply sufficient air into the burner, resulting in incomplete combustion of the gas source and waste of the gas source. If the wind pressure is insufficient, the flame cannot come out of the air knife and the ground cannot be burned. At the same time, since the burner is directly connected to the blower, the high temperature of the burner will also be transmitted to the blower. The traditional blower cannot withstand the heat energy transmitted by the burner, resulting in a low service life of the blower. Therefore, it is urgent to design a ground burning machine blower to solve the above problems. Summary of the invention
