Abstract

PURPOSE:To enable selection of traveling speed suitable to various conditions, by providing a high speed regulation mechanism for limiting the interlocked speed change when a continuously variable speed change mechanism is changed to the high speed side and an operating lever thereof. CONSTITUTION:In order to turn the rotation of an input shaft 16 to low speed, an operating lever 24 is operated in one direction. Consequently, a shaft 26 rotates to pull up a rod 35 thereby a push arm 15 rotates in such direction as a bush wheel 12b is not pushed so as to widen the split width of a split pulley 12. On the other hand, the rotation of an arm 38 causes a tension pulley 20 to stretch a V-belt 19 strongly. As a result, an input shaft 16 is changed to low speed. On the contrary, when the operating lever 24 is rotated in the other direction, the input shaft 16 is changed to high speed. Since the highest speed can be changed freely by means of the operating lever 24, such speed as suitable for the field conditions, the operational skill of driver and the working conditions can be selected easily.

During rice transplanting work, the rice transplanter 40 as a working machine is lowered by the lifting mechanism 44 and the soil leveling float 43 is in contact with the ground, so naturally the piston of the hydraulic cylinder device 49 is retracted, so the wire 50 becomes loose. The tension of the tension belt 19 and the spring 36 pressing the split pulley piece 12a increase the winding diameter of the pulley 12, and the gear is returned to the state where the gear is set with the gear shift operation lever 24, and the input shaft of the transmission case 8 is moved. 16 is in a state of high speed rotation, and rice planting work is performed at the traveling speed set by the operating lever 24.

即ち、操作レバー24による速度設定を説明すると次の
通りである。
That is, the speed setting using the operating lever 24 will be explained as follows.

When the operating lever 24 is rotated in the direction of arrow (A) to shift and set the shift pin 28 to the home position, the shaft 26 is rotated around the arrow (B), and the plate body 27 and arm 28 are moved to the same side. Rotated. Then, from the plate body 27, a spring 36
The rod 35 is pushed down via the lever 15a, and the pressing arm 1115 is rotated in the direction of the arrow (c), and its tip presses the bush @ 12b to move the split pulley piece 12a to the side where the split width is narrower. Move it to. On the other hand, as the arm 38 rotates, the tension of the spring 29 is loosened, so that the tension pulley 20 is rotated in a direction that reduces the tension force on the V-belt 19.

したがって、割プーリ12の割幅が狭くなると同時にV

Therefore, at the same time as the split width of the split pulley 12 becomes narrower, V
In order to reduce the tension of the belt 19, the rotation speed of the input shaft 16 is changed extremely quickly to a high speed.

また、操作レバー24のこの高速側への回動(矢印(イ
)方向)操作はばね39の張力を受けて回動し易6方向
にあるから極めて軽い操作になる。
Further, the operation of rotating the operating lever 24 toward the high speed side (in the direction of arrow (A)) is an extremely light operation because it is easily rotated in six directions under the tension of the spring 39.

Next, when it is desired to reduce the rotation speed of the input shaft 16, it is preferable to operate the operating lever 24 in the opposite direction of the arrow (A). At this time, the shaft 26 is rotated in the opposite direction of the arrow (b), the rod 35 is pulled up by the plate 27, and the suppression arm 15 is rotated in a direction in which it does not press the bush ring 12b.

したがって、割プーリ12の割幅が広がることになる。Therefore, the split width of the split pulley 12 becomes wider.

一方、アーム38の回動により、ばね39の張力が増大

On the other hand, as the arm 38 rotates, the tension of the spring 39 is increased, and the tension pulley 20 applies strong tension to the V-belt 19.

したがって、迅速に入力軸16が低速に変速される。Therefore, the input shaft 16 is quickly shifted to a low speed.

By the way, since the speed setting by the above-mentioned operating lever 24 is a stepped transmission, although the configuration is a continuously variable transmission mechanism, substantially only stepped transmission can be obtained. However, by rotating the stopper 54 with the operating lever 53, the arm 5
By appropriately restricting the upward rotation of the tension pulley 20, the tension pulley 20 can be stopped before being returned to the position set by the operating lever 24, thereby preventing rice transplanting work caused by high-speed running.

In the embodiment, two operating levers 24 and 53 are provided, but in this invention, the operating lever 24 is not particularly necessary, and in this case, the rice transplanting operation can be performed with continuously variable speed. You can set it to

Then, when the rice transplanter 40 is raised and rotated by the hydraulic cylinder device 49, when the tensioner 1122 is pulled up via the wire 50 by the protrusion of the piston, the V-belt 19 is tensioned, and the split pulley 12 is wound. The diameter of the input shaft becomes smaller, the input shaft 16 rotates at a lower speed, and the running speed becomes slower.

Then, when the rice transplanter 40 is lowered after turning, the traveling speed is increased as the rice transplanter 40 descends, and becomes the traveling speed set by the operating lever 53 described above.
