Claims

[Scope of Claim for Utility Model Registration] (1) A winding drum for winding up the towing rope of Kaibori Jyoren, a tie belt for connecting this winding drum to a drive source, and a hook that engages with the winding belt. a foot pedal that operates a tension pulley that rotates the winding drum, a planetary gear provided on an arm that rotates together with the winding drum, a sun gear that is rotated by the tuning belt, and an internal gear that is rotatably supported on the machine frame. A gear, a brake drum fixed to the internal gear, and a brake piece facing the brake drum and actuated by the foot pedal, the brake piece being actuated when the foot pedal is in a non-operating position. The winding drum is free to rotate together with the brake drum and the internal gear, and when the foot pedal is in the first operating position, the brake piece fixes the brake drum and the adjustment The winding drum is fixed without any tension applied to the band, and furthermore, when the foot pedal is in the second operating position, the brake piece firmly fixes the brake drum, and the tension pulley causes the winding drum to be fixed. A shell-digging winch device characterized in that tension is applied to the adjustment belt, the sun gear rotates, and the winding drum is driven. (2) The drive source is an engine, the throttle wire of this engine is connected to a foot pedal, and when the foot pedal is in the non-operating position, the engine is at idling speed, and when the foot pedal is in the first operating position. The shell digging winch device according to claim 1, wherein the engine rotates at a low speed, and further, when the foot pedal is in the second operating position, the engine rotates at a high speed.
