The invention provides a wood processing machine tool capable of automatically pushing wood. The wood processing machine tool comprises a planer, a travelling driving device and a retracting reset device, the planer comprises a front platen and a rear platen which are rectangularly and horizontally arranged, and a planer body arranged on the lower part of the front platen and the lower part of therear platen supports the planer, a planing mechanism is arranged between the front platen and the rear platen, the height of the front platen is less than that of the rear platen and the height difference between the front platen and the rear platen is the thickness of a planing layer, an automatic push mechanism is further movably arranged on the planer, the automatic push mechanism is used forpushing wood workpieces to be tightly attached to the front platen and then move to the rear platen after being planed by the planing mechanism, the travelling driving device is connected with the automatic push mechanism and used for providing push power to the automatic push mechanism, and the retracting reset device is used for cutting off the power output of the traveling driving device and controlling the traveling driving device and the automatic push mechanism to reset automatically.
