Claims

[Scope of utility model registration request]

(1) A device for removably attaching and setting a bushing arm for supporting work equipment such as blades to the trunnion of a tracked vehicle, which is integrally connected to the trunnion connection end of the bushing arm and fitted into the trunnion from one side. A trunnion support socket in which a half-cut support hole is formed that can be removably fitted and aligned, and a half-cut support hole that is fitted and aligned with the trunnion from the opposite side of the socket, and can be detached from the socket with a through bolt or the like. and a cylinder dedicated to attaching the bushing arm that is installed on the vehicle and lifts the socket side of the bushing arm to a height position where the socket can be aligned with the trunnion. The open end side has a tapered inner wall surface that gradually expands larger than the outer diameter of the trunnion, and the cap has a tapered outer wall surface that matches the tapered outer wall surface, so that the cap and the socket are removably fastened. A bushing arm mounting device for supporting work equipment on tracked vehicles, which is characterized by the following features:

(2) The cylinder dedicated to attaching the bushing arm must be suspended from the lift cylinder mount installed on the vehicle side via a chain, etc., and must have a hanging chain or wire rope, etc. that can be hooked onto the bush arm. A bush arm mounting device for supporting a working machine of a tracked vehicle as claimed in claim 1 of the registered utility model.

(3) The cylinder dedicated to attaching the bushing arm has a single-acting pull hydraulic cylinder configuration that moves linearly in the direction of lifting the bushing arm using hydraulic oil and returns using a spring. A bush arm attachment device for supporting a working machine for a tracked vehicle according to item 2.

(4) A bushing arm mounting device for supporting a working machine of a tracked vehicle according to claims 1 to 3 of the utility model registration, characterized in that the cylinder is connected to an attachment pump dedicated to the cylinder.
