Description

[Detailed description of the invention] This invention is based on a body frame in which the front and rear transmission cases are fixedly connected via a plurality of front and rear posture frame members placed side by side in the horizontal direction, and a passenger footrest step plate is attached in the front and rear direction. The present invention relates to a step mounting structure for a riding working machine, such as a rice transplanter, which is connected and supported via two sideways stays spaced apart from each other.

In the past, both sideways posture stays were supported on the front and rear posture frame members, but
In this case, all the step loads such as the step weight and the worker's weight act on the front and rear posture frame materials, which greatly increases the strength of the front and rear posture frame materials and the strength of the attachment of the front and rear posture frame materials to the front and rear transmission cases. However, there was a drawback that the front-rear posture frame material and the structural members for attaching the front-rear posture frame material to the transmission case became large and heavy. The increase in size and weight of such members leads to an increase in cost, and is not practical, especially for rice transplanters that are required to be lightweight because they run on soft ground such as rice paddies.

The present invention aims to overcome the drawbacks of the prior art.

The step mounting structure for a riding work machine according to the present invention includes mounting and supporting the front stay of the stays in the horizontal position on the front transmission case;
In addition, the rear stay is mounted and supported on the front and rear posture frame material group.

According to the characteristic configuration of the present invention, the step load is shared and supported by the front transmission case and the front and rear posture frame material group via the stay, so that the frame material is applied to the front and rear posture frame material and both transmission cases. The strength required for the mounting structural members is reduced, and in particular, in the frame mounting structural members of the front transmission case, the front and rear posture frame members and the front transmission case are indirectly connected with strength through the stays and step plates. By being
The required strength becomes even smaller.

Therefore, according to the present invention, it is possible to reduce the weight and size of the front-rear posture frame material and the mounting structure while ensuring sufficient step mounting strength and body frame strength.

Hereinafter, embodiments of the present invention will be described based on the drawings.

This is a riding rice transplanter in which a planting device 2 is attached to the rear of the riding machine 1 so as to be movable up and down. 4 is provided protrudingly, and the engine 5
A front transmission case 7 from which a mounting frame 6 for mounting is protruded, and a rear transmission case 10 from which axle cases 9, 9 supporting a pair of left and right drive wheels 8, 9 are protruded are juxtaposed in the lateral direction. A passenger footrest step plate 13 is fixedly connected to the fuselage frame 12 via two longitudinal frame members 11, 11.
are connected and supported via two horizontal stays 14, 14' located at a distance in the front-rear direction, and
It is constructed by attaching a driver's seat 15 and a steering handle 16.

Both stays 14, 14' are U-shaped members that open downward, and the front stay 14 is mounted and supported on the front transmission case 7, and the rear stay 14' is mounted on the frame members 11 and 11 group. The stays 14, 14' are supported on a rack, and near both left and right ends of the stays 14, 14' are connected and supported by V-shaped supporting members 17, 17, which are erected on the front axle cases 4, 4.
