The first cutting saw is used for cutting two ends of timber, and the second cutting saw is used for cutting the middle part of the timber.

Further, the stop block is a wedge-shaped block, and one side of the wedge-shaped block, which is far away from the feeding mechanism, is a vertical surface.

Has the advantages that: this technical scheme is through adopting the wedge in order realizing the promotion to timber, after timber falls into on the correction block, the contained angle that wedge lateral wall and second drive chain formed can load timber to along with the rotation of second drive chain, timber also moves thereupon.

Furthermore, the tail end of the rack is fixedly connected with a guide plate.

Has the advantages that: this technical scheme is through setting up the deflector in order to realize the guide effect to timber, ensures that the timber after being cut can be concentrated the drop in appointed position under the effect of deflector direction.

Further, the correcting block is coaxially connected with a first driving motor.

Has the advantages that: this technical scheme is through adopting first driving motor in order to realize the drive effect to the correction block. Because adjacent correction block utilizes first driving chain to realize transmission each other, consequently a driving motor only drives a correction block, can realize carrying out the transmission to all transmission blocks.

Further, the tail end of the square pipe is located above the first transmission chain.

Has the advantages that: this technical scheme is through the position of the square pipe of injecing to when guaranteeing timber to roll down on square pipe, can also carry out the secondary transportation with timber.

Furthermore, the tail end of the square pipe is fixedly connected with a guide plate.

Has the advantages that: this technical scheme sets up the baffle through the end at square pipe to the realization leads timber to leaving cutting mechanism.
