<p>PURPOSE:To obtain the furrowing device designed to enable proceeding with digging seeding furrows at a specified depth without wrapping waste straw on the ground on the ratchet wheel shaft proceeding with digging seeding furrows on the ground while rotating opposite to machine body traveling. CONSTITUTION:Both ends of the shaft 5 of ratchet wheels are supported rotatably by two arms 4 provided on the machine body and the arms 4 is also equipped with a transmission mechanism 8 to transmit the mechanical power from an engine to the wheel shaft 5. By this scheme, waste straw, etc., sprung up by the ratchet wheels fall on the ground and do not wrap on the wheel shaft; therefore, seeding furrows can be dug continuously at a specified depth.</p> |
