を特徴とする作業機のゲージ輪調整装置。[Scope of claim for utility model registration] Support frame 1 pivotally connected to machine frame 4 so as to be able to swing vertically
6 is equipped with a gauge wheel 15, and a support shaft 39 is rotatably supported around a horizontal axis by a support member 38 protruding upward from the machine frame 4.
is inserted orthogonally and supported rotatably around the axis,
A rod 35 is screwed onto the rotation shaft 36 and moved forward and backward in the axial direction with respect to the rotation shaft 36 as the rotation shaft 36 rotates around the axis. In a gauge wheel adjustment device for a work machine, in which a rod 35 is pivotally connected to a support frame 16 for vertically swinging, a storage recess 50 in the axial direction of the rotation shaft 36 is formed on the support shaft 39 side, and this storage recess 50 is formed on the support shaft 39 side. The recess 50 is provided with a locking body 52 that protrudes freely from the storage recess 50 and is provided with a spring 51 that biases the locking body 52 in the protruding direction. The contacting receiving member 44 is fixed, and a locking recess 53 is formed in the receiving member 44 to releasably engage the locking body 52 to restrict rotation of the rotation shaft 36 around the axis. Features: Gauge wheel adjustment device for work equipment.
