Further, a plurality of blades are fixed radially on the outer peripheral surface of the chipper disk of the pulverizing mechanism 32 to generate a conveying air so that the pulverized pulverized material moves to the discharge unit 4 side. ing. In the crushing chamber 3, a plurality of helically arranged cutting blades are provided, and the cutting blades rotate on an axis parallel to the traveling direction, thereby discharging trees and the like while roughly crushing the trees. It is also possible to adopt a configuration of transporting to the unit 4.

At the front of the crushing chamber 3, there is provided a discharge unit 4 composed of a slower or the like, and a front opening of the crushing chamber 3 and a rear opening of the discharge unit 4 are connected via a supply port 31. The discharge unit 4 is provided with radially arranged blades 41 on a support shaft 43 supported in the front-rear direction so that the crushed material is bounced off. It can discharge from the discharge cylinder 5 in an arbitrary direction.

The rear opening of the crushing chamber 3 is connected to the front opening of the charging unit 2 so as to serve as a path for input materials such as trees. The charging unit 2 is disposed so as to protrude rearward from an upper portion of the main body frame 1. The charging unit 2 has the charging unit side walls 22, the charging unit upper surface 23, and the charging unit bottom surface 24 integrally provided on the main body frame 1, and has a rectangular charging port 25 opened rearward and outward at the rear end of the charging unit 2. It was done. However, it is also possible to open in the laterally outward direction.
