Problems solved by technology

Therefore, the transmission structure in the gearbox becomes complicated, and there are problems such as an increase in manufacturing cost and an increase in the size of the gearbox.
[0005] In addition, in the walk-type rice transplanter of Patent Document 1, a high-low two-stage speed changer (22 in Fig. 4 of Patent Document 1) is provided on the path of transmission to the driving transmission shaft, and the transmission to the crankshaft of the rice transplanting mechanism There is no derailleur set on the path
Therefore, there is still room for improvement in realizing the variable speed of the rice transplanting mechanism so as to improve the working efficiency of rice transplanting

Embodiment approach

[0184] In the above [Best Mode for Carrying Out the Invention], the first transmission shaft 33 is overlapped with the output shaft 30 of the engine E, but it is not necessary to make the first transmission shaft 33 and the output shaft 30 of the engine E on the same axis. They are arranged overlappingly in the direction of the heart P1 and connected in series. In this case, for example, the first propeller shaft 33 can be connected to the output shaft 30 of the engine E via a coupling member or the like (not shown).

[0185] In the above [Best Mode for Carrying out the Invention], the first transmission shaft 33 and the output shaft 30 of the engine E are arranged concentrically, but the axis center of the first transmission shaft 33 and the output shaft of the engine E may also be arranged concentrically. The axes of 30 are eccentrically connected side by side. In this case, for example, the output shaft 30 of the engine E may be connected to the first transmission shaft 33...

Abstract

The invention provides a drive structure of a walking type transplanter, capable of simplifying the drive structure in a gear box and shifting a running drive system and a transplantation drive system. In the drive structure of the walking type transplanter, a first drive axle (33) into which the power of an engine (E) is input and a second drive axle (37) for branching the power from the first drive axle (33) to the running drive system and the transplantation drive system is set on a gear box (M) and a gear shifting part (39) is set across the first drive axle (33) and a second drive axle (37) and the gear shifting part (39) shifts the power transferred into the running drive system and the transplantation drive system.

Description

technical field [0001] The invention relates to a transmission structure of a walking rice transplanter which branches and transmits power from an engine to a driving transmission system and a rice transplanting transmission system. Background technique [0002] In the prior art, for example, the structure of the disclosed walking rice transplanter in Patent Document 1 is: the power from the engine is transmitted to the first transmission shaft (Patent Document 1 18 in FIG. 4 of , which is transmitted from the first transmission shaft to the traveling transmission shaft (20 in FIG. 4 of Patent Document 1) via the second transmission shaft (19 in FIG. 4 of Patent Document 1), and The power from the engine is branched and transmitted to the third transmission shaft (36 in FIG. 5 of Patent Document 1) via the intermediate transmission shaft (17 in FIG. 5 of Patent Document 1), and from the third transmission shaft via the fourth transmission shaft (37 in FIG. 5 of patent docum...
