Description

[Detailed Description of the Invention] The present invention relates to a riding type rice transplanter, and particularly relates to an improvement of the step.

In general, riding rice transplanters are used for driving in rice fields, etc.
For example, the base of a Cheno case extending diagonally rearward and downward is fixed to the tip of a boss portion that wraps around the drive shaft protruding from the left and right outer surfaces of the transmission case, and the rear wheel is pivotally supported on the rear end of the Cheno case. There were other problems, such as when getting on and off the vehicle, one's feet could get stuck in the chenoke case and dent it, and there was a large gap between the chenoke case and the rear wheels, so it was dangerous if one's body got between them.

This invention prevents damage to the chenoke case by preventing feet from getting on the chenoke case when getting on and off the vehicle, and
The purpose of this is to reduce the distance between the chenoke case and the rear wheel to prevent the human body from getting into the space, thereby preventing danger.

In other words, in order to achieve the above-mentioned object, the present invention provides a step above the base side of the chenoke case so that the foot does not rest directly on the chenoke case when riding, and also connects the outside edge of this step with the inside of the rear wheel. The step is characterized in that the step is provided in an overhanging manner so as to be close to the periphery.

Hereinafter, one embodiment of the present invention will be specifically described with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a vehicle body of a riding rice transplanter, and an engine 2 is mounted on the front portion of the vehicle body 1, and a transmission case 3 is provided at the rear portion.

A drive shaft protrudes from both sides of the transmission case 3, and the front end of a cheno case 5, whose rear end also serves as a support arm for supporting the rear wheel 4, is attached to the tip of a boss that surrounds the drive shaft. Driving force is transmitted from the engine 2 to the rear wheels 4 via a transmission means including a gear transmission mechanism in a mission case 3, a sprocket in a chino case 5, an endless chino, and the like.

Further, a front wheel 6 is attached to the front part of the vehicle body 1, and the front wheel 6 is steered by operating a steering handle 7.

A three-point hitch link mechanism 8 operated by a hydraulically operated mechanism is provided at the rear of the vehicle body 1, and a rice transplanting machine 9 is connected via this hitch link mechanism 8 so as to be movable and detachable.

This rice transplanting work machine 9 is a commonly used one that is equipped with a transmission mechanism 10, an implant 11, a seedling stand 12, and a float 13. The driving force is transmitted to carry out the planting work.

A step 14 is disposed above the front end of the chain case 5, and the base of the line marking marker 15 is fixed to the art material side end surface of the chain case 5, located below the step 14.

The line marker 15 has a base bracket 16 fixed to the chain case 5 so that its front part projects from the front end of the chain case 5, and a base rod 17 that projects outwardly together with the bracket 16 and also serves as an auxiliary step. are provided, and these constitute the base 15a of the line marking marker 15.

An intermediate rod 19 is connected by a vertical shaft 18 to the tip of the base rod 17 that protrudes outward from the step 14, and a hook-shaped wire rod 20 is connected to the intermediate rod 19 by a horizontal shaft 21.

As shown in FIG. 3, the intermediate rod 19 and the line forming rod 20 are connected by a spring 22 and a link 23, and an operating lever 24 is connected to the link 23.

Then, by operating the operating lever 24, the wire attaching rod 20
By rotating the body 1 about the horizontal axis 21 and driving the vehicle body 1 with the tip rod 20a of the liner rod 20 facing downward as shown by the solid line in FIG. 3, the tip rod 2 is attached to the field.
A groove-like line is attached at 0a, the vehicle body 1 is turned back, and the rice transplanter is operated using the line attached during traveling as a standard.

When it is time to stop lining, the tip rod 20a is turned sideways and held above the field surface as shown by the chain line in FIG. 3 by operating the operating lever 24 in the opposite direction.

Furthermore, when storing, the intermediate rod 19 is rotated about the vertical axis 18 to rotate it forward (or backward), and the tip rod 20a is rotated around the axis relative to the attachment rod 20b of the line forming rod 20. By rotating it and directing it forward or backward as shown by the arrow in FIG. 3, the amount of protrusion of the line marker 15 toward the outside of the vehicle body 1 is reduced.

Furthermore, as is clear from FIG. 2, the step 14 protrudes so that its outer edge approaches the inner circumferential edge of the rear wheel 4, preventing a human body or the like from entering between the chain case 5 and the rear wheel 4. Hazards are prevented.

Note that the reference numeral 25 in FIGS. 1 and 2 is a seat disposed between the left and right chain cases 5, and the reference numeral 26 in FIG. pins, 2 to hold them in position for storage and use;
7 is a push screw for tightening and holding the attachment rod 20b of the wire attachment rod 20 and the tip rod 20a in a predetermined position.

In the present invention, in the above embodiment, the base of the lined marker was also used as an auxiliary step, but the planted shoots are detected,
With this as a standard, the base of the row alignment marker on which the rice transplanter travels may also be used as an auxiliary step, and it goes without saying that the configuration of the marker itself can be changed as appropriate.

As explained above, the riding type rice transplanter of the present invention has a step placed above the base side of the chain case to prevent feet from directly touching the chain case when riding, thereby preventing damage such as denting of the chain case. In addition, the step protrudes so that the distance between the outer edge of the step and the inner edge of the rear wheel is close, so that there is no chance of a human body, etc. falling between the chain case and the rear wheel. It has the effect of being safe without getting into it.
