Description

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, a control handle and its support rod extend from the aircraft body so as to be able to swing up and down, and are connected to each other in order to fix their swing. The mounting height of the control handle is changed by changing the connecting position of the rod, and the supporting rod is moved up and down as the mounting height is changed, and the traveling gear lever is extended from the fuselage. The purpose of this walk-behind mobile agricultural machine was to change the installation height of the gear shift lever in the same direction as the control handle in conjunction with the operation to change the control handle installation height, and to have a simple structure for this purpose. It's about making sure you get it.

The characteristic configuration of the present invention is that, in the above-mentioned walking type mobile agricultural machine, a flexible portion is provided that allows relative vertical movement of the speed change lever and the operated member thereby, and the speed change lever and the support rod can be raised and lowered integrally. The reason is that it is connected to

In other words, in the above-mentioned steering wheel configuration, the higher the steering wheel is raised as the steering wheel support rod is raised, so by providing the flexible portion and connecting the gear shift lever and the steering wheel support rod so that they can be raised and lowered together, As the handle support rod is raised and lowered, the mounting height of the gear shift lever changes in the same direction as the control handle, and the interlocking structure for this purpose can be easily obtained.
As a result, even if workers are of different heights,
The gear shift lever can be easily operated and gears can be changed easily, and there is no need for special adjustment effort, making it possible to provide a convenient device at a low cost.

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

As shown in Figures 1 and 2, five weed pulling tools 1 for planted stem culms of rice, wheat, etc. are arranged in parallel in the lateral direction of the machine, and five stem culm pulling paths are provided. A reaping device 3 uses a rotary packer 2 to form a culm of planted stems introduced into each of the routes R as the machine travels.
The harvested stem culms are conveyed to the right lateral end of the machine body in an upright position by the conveying claws 5 of the pair of upper and lower endless rotation chains 4 and 4, and are continuously discharged outward to the right side of the machine body. A working unit configured as shown in FIG. The motive power is transmitted from the running body to the working section through the transmission case 9, thereby forming a walking type reaping machine.
In addition, the rod 10 shown in FIG.
This is to display the right edge of the cutting width.

As shown in FIG. 3, the control handle 8 extends from the front end of the traveling machine to the rear of the machine so as to be swingable up and down about the axis of the pivot shaft 11, and extends from the front end of the traveling machine to the rear of the machine. The extending end side of the handle support rod 13 made of a bent pipe, which extends rearwardly so as to be vertically swingable around the axis of the pivot shaft 12, is attached to the bracket 14 which is biased toward the extending end side of the operating handle 8. The control handle 8 and the support rod 13 are connected by bolts 15 and locked to prevent them from swinging relative to the aircraft. Moreover, the plurality of mounting holes 16 for the bolts 15...
are arranged in parallel in the axial direction of the handle support rod 13 in the longitudinal direction of the aircraft body, and the connection position of the handle support rod 13 to the bracket 14 is changed to change the mounting height of the control handle 8 to the aircraft body. In addition, the support rod 13 is configured to move up and down as the mounting height changes.

As shown in FIGS. 3 and 4, transmission case 1
7 is equipped with a traveling gear transmission (not shown) that can be switched to one stage each for forward and backward movement, and the sliding operation shaft 18 of the transmission is made to protrude from the transmission case 17 to one side of the fuselage. A lever 21 is linked to the sliding operating shaft 18 so that it can move up and down relative to the sliding operating shaft 18 by an interlocking pin 19 attached to the projecting end of the sliding operating shaft 18 in the vertical direction of the machine body and a fork 20 that is engaged with the linking pin 19 so as to be able to move up and down. is arranged between the pair of left and right parts of the handle and the support rod 13 in the longitudinal direction of the machine body, with the grip extending rearward from the machine body, and
The handle support rod 13 is pivotally connected to the connecting portion 13a between the front and back parts of the body so as to be able to swing left and right and move up and down in one piece, so that the lever 21 can be moved left and right around the pivot axis P relative to the handle support rod 13. The aircraft can be moved forward or backward by swinging.

As shown in FIG. 5, the pivoting connection structure of the lever 21 to the connecting portion 13a of the handle support rod 13 is such that a cylindrical shaft member 13b in a vertical posture is integrally connected to the connecting portion 13a, and the lower surface of the lever 21 is connected to the connecting portion 13a. A shaft member 13c projecting downward from the side is rotatably fitted into the cylindrical shaft member 13b, and the end of the shaft member 13c protruding from the cylindrical shaft member 13b is provided with a splitter to prevent it from coming off. A pin 13d is inserted through it.

In order to enable relative vertical movement between the lever 21 and the operating shaft 18, which is the operated member, various structures such as a universal joint can be adopted instead of the fork structure shown in the above embodiment. are collectively referred to as the flexible section 20.

Further, the present invention can be applied to cases where the forward/reverse switching lever changes only the forward speed or can change each of the forward/reverse speeds to two or more speeds, and these are collectively referred to as the speed change lever 21. .

Further, the present invention can be applied to various types of walking-type mobile agricultural machinery such as binders and walking-type tillers.

Incidentally, although reference numerals are written in the claims section for convenient comparison with the drawings, the present invention is not limited to the structure shown in the accompanying drawings.
