Description

[Detailed Description of the Invention] This invention enables the culm binding device to perform the culm binding work well by always aligning the stock base regardless of the length of the culm discharged from the threshing machine. The purpose is to

For this purpose, the following technical measures were taken.

That is, the culm supply port (2a)A>the culm discharge port (21)■
A threshing machine (with an automatic culm feeding device (3)
2) Look into the culm outlet (2b) and install the culm binding device (
4), which is located on the side of the stock base of the culm that is transferred from the culm discharge port (21)) d to the culm bundling device (4), and which aligns the base of the culm. A root leveling device (6) is provided, and the root leveling device (6) is configured to be operable along the culm direction of the culm, and elastically biased toward the tip side of the culm. The structure of the thresher is equipped with a stock leveling device.

An embodiment of the present invention will be described below.

First, the structure will be explained. (1) is a reaping transport frame rotatably mounted on the front part of a vehicle chassis equipped with a traveling device (not shown).

(2) is a threshing machine which is mounted on the chassis behind the reaping transport frame (1) and has a culm supply port (2a) and a culm discharge port (2b).

(3) is an automatic culm feeding device that pinches the grain culm fed into the threshing machine (2) and transfers it from the culm supply port (2a) to the culm discharge port (2b). .

(4) is a culm binding device detachably installed on the machine frame on the side (in the embodiment, rear) of the culm discharge port (2b).

(5) is the culm outlet (2b) and the culm binding device (4).
This is a culm conveying device installed between the two.

(6) is a guide surface (6a) that acts to guide the culm at a portion through which the culm's culm head passes near the culm binding device (4);
A stock alignment device having a stock alignment device (6
) is movable along the culm direction of the culm supplied to the culm binding device (4) by a parallel link mechanism (8) provided on the appropriate frame body (7) of the culm binding device (4). In addition, the guide surface (6a) is configured to always bounce toward the tip side of the culm due to the spring (9).

In the upper configuration, first, the prime mover (not shown) is started and the rotating parts of the machine are driven to move the machine forward and work begins. When the grain culm group reaches the end of its conveyance, it is taken over by the grain culm automatic feeding device (3) and fed into the threshing machine 1 (2), thereby opening the grain culm supply port (2a).
) side to the culm outlet (2b) side.

The culm discharged sequentially from the culm discharge port (2t) d is transferred to the culm conveying device (5) and further conveyed, and when it reaches the end of the conveyance, it is transferred to the culm binding device (4). It is fed there, bundled in predetermined amounts, and discharged outside the machine.

However, the length of the culms planted in the field varies depending on the region, variety, or the cutting height within the field. The bundling action may not be performed properly, such as insufficient bundling, or the bundled culms may fall apart and scatter on the field, requiring a great deal of effort to clean up afterward. It takes.

Furthermore, in a system that is configured to be manually adjusted using screws, etc., the harvesting operation is carried out continuously, so if the cutting height of the husk or the depth of handling to the threshing section is changed as described above, the length of the culm may be changed. It is almost difficult to adjust for different sizes.

In this case, the stump head of the culm being fed into the culm binding device (4) is guided by the stump head alignment device (6) which is always elastically biased toward the tip side of the culm. They are guided to the binding device (4) while being aligned by the surface (6a).

At this time, if the culm is long, it will be guided by the abutting force of its stock head, and if the culm is short, the stock head alignment device (6) will be guided by the spring (9).
) by the restoring force, it moves toward the tip of the culm (in the opposite direction of arrow A) and guides the base of the culm stock. In other words, the stock head alignment device (6) can automatically move depending on the length of the culm to prevent the stock head from bunching depending on the length of the culm, and this movement is caused by the spring (9). Therefore, the configuration is simple.

The waste culms that have undergone the alignment action as described above are quickly sent to the waste culm binding device (4), where they are tied in predetermined amounts and discharged outside the machine. When done, the culms will not be scattered due to irregularities.

As described above, the present invention is configured such that the plant head alignment device is movable along the direction of the culm of the discarded culm, and is configured to be elastically biased toward the tip side of the discarded culm. Therefore, even if the length of the stump head of the culms that are continuously fed into the culm bundling device changes, the stump head alignment device automatically moves according to the change in the stump head each time. You can guide the base of the culm stock by
- Although the work efficiency is improved by preventing the hassle of manual adjustment, the moving configuration of this stock head leveling device that responds to changes in the stock head part makes it possible to eliminate culms from the stock head leveling device. Since the configuration is sufficient to simply spring bias toward the tip side, there is no need to provide a moving device for moving a special complicated stock alignment device such as a hydraulic device, and related parts. Since the number of points can be reduced, the configuration can be simplified, which has an extremely practical effect.

Claims (1)

[Claims] The culm is discharged by looking into the culm discharge port (2b) of a thresher (2) having an automatic culm feeding device (3) that transfers the culm from the culm supply port (2a) to the culm discharge port (2b) side. It is equipped with a binding device (4), and is located on the side of the stock head of the waste culm transferred from the culm discharge port (2b) to the waste culm bundling device (4), and is disposed of along with the waste culm stock base. A threshing machine with a stock leveling device that is biased toward the tip of the culm.
