Abstract

A paddy field operation machine. A front part of a machine body has transmissions (18, 19) for driving, a driving transmission shaft (20) that transmits power from the transmissions (18, 19) for driving, and a front wheel differential mechanism (21) that transmits power to a right front wheel and a left front wheel (1). Power of the driving transmission shaft (20) is transmitted to the front wheel differential mechanism (21) by means of first transmission mechanisms (20a, 21b). A rear wheel transmission shaft (22) that transmits power to a right rear wheel and a left rear wheel (2) is arranged, and power of the driving transmission shaft (20) is transmitted to the rear wheel transmission shaft (22) by means of second transmission mechanisms (20b, 22a). The abovementioned paddy field operation machine can realize improvement of durability of the front wheel differential mechanism and low cost.

Description

technical field [0001] The present invention relates to a structure of a driving transmission system that transmits power to front wheels and rear wheels in paddy field work machines such as a passenger-type rice transplanter and a passenger-type direct seeding machine, and a power transmission system that transmits power to paddy field work equipment included in the machine body Construction of the transmission system. Background technique [0002] The structure disclosed in patent document 1 exists in the riding-type rice transplanter which is an example of a paddy field working machine. [0003] In Patent Document 1, a traveling transmission and a front wheel differential mechanism that transmits power to the right and left front wheels are provided at the front of the body, and the power of the traveling transmission is transmitted via spur gears. For the front wheel differential mechanism (differential case). It is also configured to have a rear wheel propeller shaft ...
