Claims

[Scope of utility model registration request]

In a dozer device for construction machinery, in which a frame body is provided in the front part of the lower traveling body so as to be movable vertically and an earth removal plate is attached to the frame body, a bracket member is provided on the rear face of the earth removal plate, A pin hole is formed in the left and right direction in the bracket member, a ripper is formed, a pin hole is formed in the base end of the ripper along the width direction, and the base end of the ripper is attached to the bracket. It is pivoted to a member with a pin so that it can move up and down, and when the tip of the ripper blade is allowed to hang downward, the tip of the ripper blade protrudes to a lower position from the lower edge of the earth removal plate, and the ripper is attached to the above-mentioned bracket. What is claimed is: 1. A dozer device with a ripper, characterized in that the ripper is configured to be fixedly latched to a member, and the ripper is configured to be able to be fixedly stored in the bracket member when the tip of the ripper blade is rotated upward.
