The invention discloses an automatic logging machine, which includes a logging device, a transmission device, a push pincer, a vertical saw blade, a first horizontal saw blade, a second horizontal saw blade, a first chassis, a second chassis, etc., the logging device There are three vertical saw blades on the upper front; this automatic logging machine realizes the integration of tree cutting and transportation through the logging device and the transmission device, and realizes the flexible cutting of small-diameter trees and branches through the set vertical saw blades , the function of cutting the upper and lower kerfs of large-diameter trees is realized by setting the first transverse saw blade and the second transverse saw blade, and the function of pushing and hanging the trees is realized by the push pliers. The first rotating arm, the second rotating arm and the third rotating arm realize the adjustment of more degrees of freedom of the logging device. Compared with the existing logging equipment, the automation degree of the automated logging machine is higher, the logging efficiency is higher, and the function is stronger.
