8. The method of sawing bamboo according to claim 7, wherein the bamboo joint detecting device is a visual detecting device, and the bamboo joint detecting device detects whether the bamboo section cutting point is a bamboo joint specifically: the visual detection device acquires image information of the bamboo section cutting point positions, and judges whether the bamboo section cutting point positions are bamboo joints or not by analyzing corresponding pixel points of the image information.
9. The bamboo sawing method according to claim 8, further comprising a cull sawing device arranged behind the clamping conveying member with respect to the conveying direction;
The bamboo sawing method further comprises the steps of: when the length of the raw bamboo is 1 to 2 times of the length of the bamboo section, the conveying is stopped when the clamping conveying piece conveys the front end part of the raw bamboo to a third position, the residual sawing device cuts the raw bamboo to a fixed length to form the bamboo section, and the distance between the third position and the sawing mechanism is the length of the bamboo section minus the distance between the sawing mechanism and the residual sawing device.
