Description

[Detailed description of the invention] TECHNICAL FIELD The present invention relates to a reaping and harvesting machine for binders and the like.

This type of reaping and harvesting machine normally has a pair of left and right running wheels mounted on the machine body at a certain interval, but when working in wet fields, the left and right wheels are placed close together to form one wide wheel. By using the wide left and right wheels to travel over stumps, the aircraft can travel while preventing the aircraft from sinking.

However, in order to adjust the wheel spacing in this way, in the past, each wheel was supported on a single axle, the mounting position of this axle in the axial direction was changed and adjusted, and then the wheels were connected using bolts or pins. Therefore, it is necessary to attach and remove bolts and pins each time the wheel spacing is changed, making it cumbersome to adjust the wheel spacing.

In particular, in agricultural machinery, straw, grass, mud, etc. tend to adhere to the axle portion of agricultural machinery, making the above operation even more complicated.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to enable the wheel spacing to be changed and adjusted smoothly and quickly.

Embodiments of the present invention will be described in detail below with reference to the drawings.

The figure shows a binder.

This binder includes a transmission case 2 that is directly connected to the rear engine 1, a transmission case 3 that is connected to the lower part of the transmission case 2, and a pair of left and right running wheels 4a and 4b that are pivotally supported at the lower part of the running transmission case 3. A reaping binding section consisting of a pulling device 6, a reaping device 7, a binding device 8, etc. is connected to the front part of the present invention, which comprises a control bundle 5, etc., which extends rearward from the upper part of the mission case 2. has been done.

Further, as shown in FIG. 4, an axle 9' is mounted horizontally in a cantilevered manner in the lower part of the transmission case 3, and a spline is provided inside the axle 9. An interpolated axle 10 is mounted which is connected to the vehicle and is slidably displaceable only in the axis X direction.

The wheels 4a and 4b are mounted on the outer end of the external axle 9 and the outer end of the inner axle 10, respectively, and the output of the engine 1 is transmitted to the transmission case 2 and the transmission case 3. The transmission is transmitted to the drive sprocket 13 fixed to the axle 9 through a transmission mechanism inside the axle 9, 1.
0 is configured to be rotationally driven.

Further, a rotating screw shaft 11 is screwed into the inner axle 10 .

This screw shaft 11 is rotated by manual operation via a rotating bundle 12 which is removably fixed to the angular shaft portion 11' projecting to the other side of the transmission case 3. It is configured to change and adjust the position of the running wheel 4b in the axial center X direction with respect to the running wheel 4a by screwing in the direction.

With this adjustment, both running wheels 4a and 4b are brought into a state shown in FIG. 3 in which they come into close contact with each other to form a single wide wheel, and a state in which they are arranged facing each other with a fixed interval as shown in FIG. 2. The relative spacing is changed and adjusted accordingly.

The screw shaft 11 and the inner axle 10 are fixed after adjusting the position of the running wheel 4b in the axial direction X direction via the screw shaft 11, since the screw shaft 11 also rotates as the inner axle 10 is driven to rotate. , have it,
The fixed state is achieved by maintaining the relative posture between the screw shaft 11 and the inserted axle shaft 10.

In other words, the screw shaft 11 is rotatably held in the small-diameter neck portion between it and the protruding angular shaft portion 11' by the lid member 14 attached to the outer surface of the transmission case 3. Movement is prevented, and the interior axle 10 is indirectly fixed from being pulled out in the direction of the axis X via this screw shaft 11.

In the illustrated example, the transmission case 3 is positioned on the side of the fuselage, and the side wheels 4a, 4b are positioned approximately at the center of the fuselage in the left-right direction.

According to the above configuration, the rotating bundle 12 is attached to the rotating screw shaft 11.
If the rotary bundle 12 is rotated in the desired forward and reverse directions, the position of the running wheel 4b in the axial center The relative spacing is changed and adjusted so that the wheels are brought into close contact and become one wide wheel.

If the side wheels 4a and 4b are arranged to face each other on the left and right, the body can be stably supported by the cooperation of the side wheels 4a and 4b, and if they are formed into a single wide wheel, this can be used when working in wet fields, for example. By running on stumps with wheels, the machine body is prevented from sinking, and can also run smoothly in narrow places such as when running on ridges.

Although not shown as an example, a member that comes into contact with the protruding square shaft portion 11' of the screw shaft 11 to prevent rotation of the screw shaft 11 is attached to the transmission case 3.
It is also possible to adjust the required distance between the wheels 4a and 4b by relatively rotating the inner axle 10 and the screw shaft 11 using the running force when the machine body moves forward and backward.

The above are examples of the present invention.

As is clear from this embodiment, the reaping and harvesting machine of the present invention is a self-propelled reaping and harvesting machine in which an axle 9 is horizontally mounted on the lower end side of the traveling transmission case 3 in a cantilevered manner. An inner axle 10 is installed inside the axle 9 and can be slidably displaced and fixed only in the direction of the axis X of the axle 9.
Wheels 4a and 4b are attached to the outer end of the inner axle and the outer end of the inner axle 10, respectively.In order to adjust the distance between the wheels 4a and 4b, it is necessary to attach the wheel 4b on one side. Since this is done by slidingly displacing the installed inner axle 10 in the direction of the axis X, it has become possible to extremely easily adjust the required wheel spacing with the wheels 4a and 4b still attached.
