Abstract
A weeding machine and a weeding method for seedlings in a paddy field are disclosed. The weeding machine includes a paddy field power chassis, a lifting hydraulic cylinder, a parallelogram suspension frame, a weeding frame, a transmission assembly, and weeding units. The paddy field power chassis vertically adjusts the working depth of the weeding machine through the parallelogram suspension frame and the lifting hydraulic cylinder. The power is transmitted to the weeding units by the transmission assembly. The weeding units are used for pulling out weeds between rows and feeding the weeds to weed chopping channels. Spiral weed chopping knives are used for chopping the weeds and conveying the weeds to feeding channels. Bidirectional variable-pitch augers are used for conveying the chopped weeds to discharge openings of the feeding channels under pressure and discharging the chopped weeds for burying weeds between plants.
