In the primary processing of bamboo, the raw bamboo must first be cut into a set length according to the needs. Generally, the raw bamboo is cut into bamboo tubes (i.e. bamboo segments) of the required length by a bamboo sawing machine. This sawing operation is called raw bamboo segmentation or raw bamboo length determination. Then the piles of bamboo tubes are manually sorted (according to the diameter, Wall thickness size, surface defects and other parameters required for specification classification), the same cylinder wall Bamboo tubes of corresponding specifications are sent to the corresponding bamboo splitting machine (also known as bamboo breaking machine) for splitting to obtain bamboo strips of set width.

An overpass type high-efficiency bamboo tube transport method, characterized in that: The method comprises the following steps: 1) feeding: cutting the raw bamboo into bamboo tubes (i.e. bamboo segments) of required length by a bamboo sawing machine and conveying them forward through the conveyor belts of the first conveyor line; the identification element on the bamboo sawing machine collects the diameter and wall thickness information of each bamboo tube (i.e. bamboo segment) at the cross section and transmits it to the control center of the bamboo sawing machine; 2) material selection: according to the preset diameter and wall thickness of the bamboo tube by each bamboo splitting machine, Wall thickness The control center of the bamboo sawing machine obtains the real-time data parameters of each bamboo tube according to the parameter requirements such as size, and selects to start the corresponding lifting and steering mechanism set beside the conveyor belt of the first conveyor line, so that it can grab the corresponding bamboo tube and turn it to be placed on the corresponding conveyor belt of the second conveyor line; 3) Splitting: the bamboo tubes on each conveyor belt of the second conveyor line are transported forward to the feeding end of the corresponding bamboo splitting machine, and the bamboo tubes are split by the bamboo splitting machine.
