AI Technical Summary
The fan speed is limited by the speed of the drug delivery pump, and it cannot rotate at high speed, which affects the blowing speed of the drug droplets.
The speed increaser structure is adopted to transmit the rotational power of the power source to the speed increaser. The speed increaser increases the speed of the fan through gear transmission and drives the fan shaft to rotate through the output shaft of the speed increaser, which reduces slippage and maintenance inconvenience of belt drive.
The increased fan speed reduced belt slippage and maintenance inconvenience, ensuring that pesticide droplets could be quickly delivered to crops.
