Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a moving agricultural machine represented by a ridge coating machine, a mid-till management machine, etc. The device is connected to a traveling aircraft.

It has a pair of 11 parts on the left and right, and a large steering wheel.

When the Missillon case is in a vertical or nearly vertical posture when viewed from the front, the left and right grips are located in the same or almost the same horizontal plane! This invention relates to a walking-wheel-type agricultural machine that is fixedly connected.

In such a walking cage-wheel type mobile agricultural machine, there is one running wheel.
1. For example, like a mobile agricultural machine with a pair of left and right running wheels, the machine body cannot be tilted from side to side due to unevenness of the running surface.
As in the conventional example shown in the figure, the running wheel
') 2>1 Same - Hahoho If the traps are placed in a vertical position when viewed from the front in positions located in the same horizontal plane, the following inconvenience will occur.

In other words, when it comes to mobile agricultural machinery.

■ In order to lower the center of gravity of the aircraft and increase the stability of the aircraft, install the single-layer power unit (3) as low as possible. ◎ Ninth to improve the left-right balance of the aircraft.

Locate the ground contact portion (1a) of the traveling vehicle (1) below or near the center of gravity of the aircraft.

θ Ninth, in order to achieve general versatility, it is required to be able to freely select and install from small-diameter running wheels for dry fields to large-diameter running wheels with excellent wet field performance. However, if the conventional transfer farm is constructed to satisfy the above requirements, as shown in FIG.
1) in order to avoid the running wheels il+ coming into contact with the prime mover (3).

If a large-diameter traveling wheel with excellent wet paddy performance cannot be installed, and the configuration satisfies the above requirement of θ.

As shown in Fig. 9, the position of the prime mover (3) is unreasonably high, or as shown in Fig. 10, the ground contact portion (1M) of the running wheel fl+ is such as a large displacement in the lateral direction.

It is not possible to satisfy the above three requirements at the same time.

In view of this, an object of the present invention is to make it possible to simultaneously perform 111 of the three requests Φ@θ.

The walking-axis type mobile agricultural machine according to the present invention is characterized by the above-mentioned Missi Cao χ
The axle for mounting the case wheel is 1! fJ is characterized in that the case is in the above-mentioned vertical position, and the tip side is provided in an inclined position at the bottom.

According to this characteristic structure, by attaching the running wheels to the axles, the left and right grooves of the handle are located in the same or almost threshold horizontal plane, and while maintaining good control performance of the aircraft, it is possible to When the wheels are viewed from the front, their ground-contacting parts are located at the center of the aircraft's center of gravity, and the upper parts of the wheels can be placed in an inclined position with respect to the ground, away from the ground, so that the ground-contacting parts of the running wheels are directly below the center of gravity of the machine. towards or near it (
By locating the IFI device as low as possible, the traveling aircraft can be positioned to maintain a balanced left-right balance, and by positioning the original IFI device as low as possible, the traveling aircraft can maintain a stable center of gravity. While maintaining the aircraft's running stability, even if the running wheels are large-diameter wheels with a radius larger than the distance between the wheels and the prime mover, the upper part of the large-diameter wheels should be It can be installed horizontally and outwardly without coming into contact with the prime mover.

Furthermore, by arranging the first axis in the above-mentioned inclined position, it is possible to position the running wheels in the above-mentioned inclined position with respect to the ground, without having to tilt the missile gear and the original equipment to the left or right. Modifying the axle of a mobile agricultural machine is an extremely simple structural improvement that can be implemented.

An embodiment of the present invention will be described below based on a ridge coating machine K (an example of a walking-axis type mobile agricultural machine) shown in the figure.

The ridge coating machine is mounted on the upper part of the Mic 1 goose (2) in a vertical position supporting the running wheel +11 in a cantilevered manner.

The frame (4) on which the original wJV device (3) is mounted is fixedly connected to the frame (4) protruding forward, and is equipped with a pair of left and right hand grips II (6m) and a control/controller (6a). '
