Title:
FURROW TRAVELING APPARATUS
Document Type and Number:
Japanese Patent JP3454686
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a furrow traveling apparatus capable of decreasing the frictional resistance of the ground and adjusting the wheel tread during traveling without using a separate actuator for extension and contraction by providing an extension and contraction driving means to extend and contract a wheel transmission shaft taking advantage of the rotational motion of the shaft.
SOLUTION: This furrow traveling apparatus is provided with a pair of right and left wheel transmission shafts connected to an output shaft 12 of a transmission case 3 to transmit the rotational power, a pair of right and left driving wheels rotated by the transmission of the rotational power of the wheel transmission shaft and an extension and contraction means to adjust the wheel tread of the pair of driving wheels by extending and contracting at least one of the pair of wheel transmission shafts in lateral direction. The extension and contraction mechanism is provided with an extension and contraction driving means 57 to effect the extension and contraction of the wheel transmission shaft by converting the rotational power of the wheel transmission shaft into the extension and contraction power in axial direction. The wheel transmission shaft can be extended or contracted by the extension and contraction driving means under the rotation of the driving wheel by the rotation of the wheel transmission shaft.
