Fixed plate is equipped with below the transmission gear, and fixed plate is fixedly connected with support column.
Compared with prior art, the utility model has the beneficial effects that：
1, the utility model is by being arranged discontinuous revolving structure, and when rotary motor starts, rotary motor is rotated forward,
It is transmitted power in power gear through speed reducer, power gear is made to operate, power gear band nutating gear is by pivoting support
After outer ring drives 180 ° of rotation, rotary motor is turned round, and when pivoting support outer ring is returned back to 165 °, baffle is overlapped with backing pin
Afterwards, it drives pivoting support inner ring to be rotated further, achievees the effect that ± 185 ° of discontinuous revolutions, effectively can increase rotation angle
It while spending, avoids in traditional swing mechanism, distorts the problem of destroying pipeline, greatly improve the angle of rotation, also,
Arc groove can effectively avoid the problem that rotation hour angle spends big or offset rotation center, improve the protection to rotating mechanism
Effect strengthens safety when use, extends the service life of the device, while can improve work using the utility model
Industry efficiency avoids the operation blind area of conventional airplane deicing vehicle.
