The specific action process of the invention is as follows: firstly, the bamboo wood 1 is neatly placed on a storage rack 32, at the moment, a support block 21, a pressing block 22 and a limiting block 23 are separated from each other, and the support block 21 is positioned below the storage rack 32; then the lifting driving mechanism 25 drives the supporting block 21 to ascend, the lifting ramp 31 ascends synchronously under the driving of the supporting block 21, when the lifting ramp 31 passes through the storage frame 32, a bamboo wood 1 at the lowest end of the storage frame 32 is lifted upwards, when the bamboo wood 1 is separated from the blocking wall 322 and slides into the V-shaped groove along the lifting ramp 31, the supporting block 21 continuously ascends, then the top end of the bamboo wood 1 is firstly contacted with the pressing block 22 and pushes the pressing block 22 upwards, the limiting block 23 is driven by the pressing block 22 to translate downwards, when the limiting block 23 is abutted against the top surface of the supporting block 21, the limiting block 23, the supporting block 21 and the pressing block 22 are abutted against each other, at the moment, the supporting plate 211 continuously ascends to compress the second elastic element 212, so that sufficient pressing force is provided for the supporting block 21, and at the moment, the positioning; then, starting a feeding action, driving the cutter bar 11 to be inserted into the bamboo wood 1 by the telescopic driving mechanism unit, unlocking the locking unit when the ejector rod 17 is extruded by the transverse partition 2 in the bamboo wood 1, ejecting the cutter head 12, starting to cut the edge of the transverse partition 2, ejecting the ejector rod 17 forwards after the transverse partition 2 is completely separated from the inner wall of the bamboo wood 1, and at the moment, because the cutter head 12 is not in a contraction state, the locking block 15 cannot fall into the locking hole 114; then the telescopic driving unit 14 retracts, the telescopic driving unit 14 drives the driving part 13 to retract firstly, and further pulls the cutter head 12 to a retracted state, at this time, the locking block 15 can fall into the locking hole 114 again, and the cutter bar 11 is driven to be drawn out of the bamboo wood 1 along with the continuous retraction of the telescopic driving unit 14; and finally, the lifting driving mechanism 25 drives the support block 21 to move downwards, when the support block 21 passes through the inclined slide way 41, the bamboo wood 1 falls on the inclined slide way 41, and when the bamboo wood 1 is separated from the V-shaped groove, the bamboo wood 1 rolls downwards along the inclined slide way 41 to a collecting device or downstream processing equipment.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be construed as the protection scope of the present invention. Structures, devices, and methods of operation not specifically described or illustrated herein are generally practiced in the art without specific recitation or limitation.
