The bamboo sawing method according to claim 5, wherein the bamboo joint detection device is a visual detection device, and in the step S1, the detection of whether the cutting point position of the bamboo segment is a bamboo joint by the bamboo joint detection device is specifically as follows: the visual detection device obtains the 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.
7. A method of sawing bamboo as claimed in claim 2, wherein the predetermined speed is 0.5-3m/s.
8. A method of sawing bamboo as claimed in claim 2 wherein the distance of the decelerated movement is 1-20cm.
9. The bamboo sawing method according to claim 3, further comprising a bamboo joint detection device disposed behind the sawing mechanism with respect to the conveying direction, the bamboo joint detection device being electrically connected to the controller;
in the bamboo sawing method, the S1 specifically comprises the following steps: detecting whether the cutting point positions of the bamboo sections are bamboo joints by using a bamboo joint detection device;
if the bamboo section cutting point position is detected to be a bamboo joint, the controller controls the clamping conveying piece to clamp the outer circumferential surface of the raw bamboo, the axial direction of the raw bamboo is driven to extend along the conveying direction to be conveyed to the position where the end of the raw bamboo extends out of the sawing mechanism by 2-20cm by utilizing the friction force between the clamping conveying piece and the raw bamboo, and the controller controls the sawing mechanism to cut off the extending part of the raw bamboo; the controller controls the clamping conveying piece to clamp the peripheral surface of the raw bamboo and convey the raw bamboo forwards at a preset speed along the axial direction of the raw bamboo;
if the bamboo section cutting point position is detected not to be a bamboo joint, the clamping conveying piece is controlled to clamp the outer circumferential surface of the raw bamboo, and the controller controls the clamping conveying piece to clamp the outer circumferential surface of the raw bamboo to convey the raw bamboo forwards at a preset speed along the axial direction of the raw bamboo.
10. The bamboo sawing method according to claim 9, further comprising a surplus material sawing device disposed behind the clamping conveyor with respect to the conveying direction;
the bamboo sawing method further comprises the following steps: when the length of the raw bamboo is 1-2 times of the length of the bamboo section, when the front end of the raw bamboo is conveyed to a third position by the clamping conveying piece, the conveying is stopped, the excess material sawing device cuts the raw bamboo at a fixed length to form the bamboo section, and the distance between the third position and the sawing mechanism is the distance between the sawing mechanism and the excess material sawing device subtracted from the length of the bamboo section.
