The conveyor belt 21 drives each limit support bar 23 to transport the log to the rotary cutting part 1 for rotary cutting. The cross section of the blocking swinging plate 3112 is a downwardly bulging curved shape, so that the log can be parallel to the first long sorting side a1 after naturally resting on the blocking swinging plate 3112, and then the log is in phase with the sorting middle beam a5. Vertical, it is convenient for the middle branch line of the log to swing up and down with the sorting middle beam a5 as the support shaft to distinguish the root end and the top end of the tree. The first elastic guide inclined plate a31 and the second elastic guide inclined plate a41 are both elastic plate-like structures, which can be steel plates. Parts of the guiding inclined plate a31 and the second elastic guiding inclined plate a41 are in contact or not, the first elastic guiding inclined plate a31 and the second elastic guiding inclined plate a41 will not affect the log swinging with the sorting middle beam a5 as the rotation axis. The first chute limit plate 3122 and the second chute limit board 3123 can assist in guiding and limiting the log. The specific structure can be as follows: the root end clamping shaft includes a first clamping shaft and a first bearing supporting the first clamping shaft; the tip end clamping shaft includes a second clamping shaft and a second bearing supporting the second clamping shaft; The diameter is greater than the diameter of the second chuck shaft, and the wear resistance and load bearing strength of the first bearing are greater than those of the second bearing. Targeted support for the root end and top end of the log can reduce the shaking amplitude of the heavier root end of the log, improve the precision of rotary cutting, and ensure the uniform thickness and stable quality of the wood chips. The size, material, etc. are controlled to reduce the cost as much as possible.
