Description

Technical field:

[0001] The invention relates to a self-shielding obstacle towing rope mechanism and a working method thereof. Background technology:

[0002] When using a rope to drag a bundle of wood or other materials on a slope, a small winch is used to release the rope, tie the material, and then the winch collects the rope for dragging. Sometimes a pulley is added to improve the smoothness of the dragging, such as the attached Figure 1 As shown (where A1 is the material, A2 is the pulley, A3 is the cable, A4 is the winch, and A5 is the obstacle), but this connection structure requires manual removal of obstacles before the dragged material can pass smoothly when it encounters obstacles such as stones and tree stumps; and it is very common for obstacles such as stones and tree stumps to appear on hillsides, which requires special personnel to take care of them, causing trouble in dragging materials.
