Description

[Detailed Description of the Invention] This invention relates to a divider opening/closing mechanism for a reaping harvester that can improve the function and safety of the divider.

In reaping and harvesting machines such as combine harvesters and binders, a divider is installed at the tip of the machine to have the function of separating entangled grain culms and guiding planted grain culms.

By the way, these dividers have a sharp point shape and are extremely dangerous in terms of their function.

Therefore, when not working, these were covered with safety guards to prevent danger, but these had the disadvantage that they were often left in the field or forgotten to be attached, resulting in an unsafe situation.

In addition, when reaping planted grain culms with a reaping harvester, the divider may not guide the grain culm properly due to the row spacing error, or the row spacing adjustment width of the divider may be small, resulting in poor growth of wheat, etc. There was an inconvenience that a different type of divider had to be replaced during reaping.

Therefore, this invention further advances the opening/closing mechanism of the divider, making it possible to suitably respond to changes in row spacing, and at the same time keeping the divider closed during non-operation (the dividers are opposed to each other on the grain culm reaping path). It also provides a mechanism in which the variable lever that operates the divider and the reaping latch lever that controls the reaping power interlock with each other.

Hereinafter, a specific example of this invention will be explained based on the drawings.

The divider 1 is mounted so as to be rotatable about a desired point by an appropriate means, such as by forming a downwardly directed shaft portion 2 on the divider 1 and pivoting it to a receiving portion 4 provided on the chassis 3 of the machine. Set up

゛Then, when divider 1 is rotated unidirectionally inward of the machine, divider 1 is raised and the path is blocked, and conversely, divider 1 is rotated unidirectionally towards the outside of the machine. In such a case, the structure is such that the tip of the divider 1 is displaced further to the outside of the machine than its normal position during normal use.

Here, the normal position during normal use refers to the position where the divider 1 is pulled up to form the route width, and in this embodiment, the vertical center line of the divider 1 is along the direction of movement of the machine. be.

Furthermore, according to this example, an operating cable 6 such as a rod or a wire is smoothly changed direction by a wheel 16 or the like from the operating piece 5 fixed to the shaft portion 2 and is extended to the control bundle 7 of the machine.

If a spring 9 is interposed between the solid hole tube 8 through which the operating cable 6 is inserted and the operating cable 6, the divider 1 is biased to rotate outward.

Further, the operating cable 6 is extended at, for example, the end on the route side and the lower side of the lifting case so as not to disturb the route of the grain culm.

The operating cable 6 extending toward the bundle 7 side is connected to a variable (cutting width) lever 10 installed at this portion.

Furthermore, a reaping latch lever 11 is disposed near the variable lever 10, and both levers 10.11 are configured to be mutually locked.

That is, when the variable lever 10 is operated to put the divider 1 in the closed state (the state in which the dividers 1 are aligned with each other as shown by the dashed line in FIG. 2) (the position shown in FIG. 1), the lever is closed. The locking piece 12 formed on the rear end side of 10 is
Lock the reaping latch lever 11 in the 1st cut position (■ position).

On the other hand, the reaping latch lever 11 is in the state where one person is in the position (■ position).
In this case, due to the presence of the end portion 13 of the lever 11, the variable lever 10 opens the divider 1 (in the reaping state, as shown in FIG. 2, A9 and C).

It is locked in the position (a position) when the locking piece 12 is in the closed position (position b), and the protruding piece 14 formed on the locking piece 12 interferes with the reaping latch lever 11. It is configured so that it cannot be operated by

Now, when reaping grain culms planted in a field with this reaping machine, even if there are changes between the rows, the raising path can be adjusted to either wide or narrow by operating the variable lever. , making suitable reaping possible.

For example, in grain culms such as wheat, which have a small stem diameter at the bottom of the stem, but whose diameter rapidly increases at the top, the 3rd diameter. As shown in Figure 4, position the tip of divider 1 at its normal position during normal use (the position indicated by the chain line in Figure 3).
By positioning the divider 1 on the outer side of the machine and allowing the machine to advance as it is, the tip of the divider 1 can be suitably avoided from colliding with the stock base, and the divider 1 can be positioned even in the area where the stock diameter increases. It becomes possible to suitably raise it at the inner edge of 1 and introduce it into the path.

Furthermore, even if the rows of planted grain culms are uneven due to row spacing errors, if the tip of the divider 1 is directed outward as shown in Figure 5, there will be no need for sudden adjustment of the direction of movement. When mowing is possible and the grain culm planted near the ridge 16 is to be reaped as shown in the same figure, the divider 1 is kept at a certain distance from the grain culm due to interference between the machine and the ridge 16. Even when it is not possible to approach the grain culms within the same range, by simply directing the tip of the divider 1 outward, grain culms that could not be harvested conventionally can be reaped suitably.

Furthermore, when the divider 1 is rotated, its rotation is completely fixed by the tensile force of the spring 9 and the variable lever 10 that is engaged with the reaping width groove 15, and there is no problem due to reaping resistance or the like. do not have.

Furthermore, danger can be prevented by setting the variable lever 10 to the closed state when the vehicle is not working on land.

In addition, in these operations, the divider 10 may be fully closed when only one person is holding the reaping latch, and the divider 10 may be fully closed.
As mentioned above, the reaping latch will not be left unattended when the reaping latch is fully closed.

As mentioned above, by adopting such a configuration, not only can the safety of workers be ensured, but also it can correspond to the planting mode of grain culms better than the conventional one, and the divider can be adjusted according to the type of grain culm.
It can be expected to have excellent practical effects, such as saving the trouble of replacing the divider with a different type, eliminating the need for a safety guard on the divider, and preventing malfunctions that could lead to equipment loss.
