Description

[Detailed description of the invention] The present invention relates to a culm collecting device in a combine harvester.

An object of the present invention is to provide a culm collection member under a cutter mechanism installed in a combine harvester so that it can be freely moved in and out in the front and rear horizontal directions with respect to the projection range of the cutter mechanism, and to automatically discharge uncut culm bundles intermittently and continuously. Release, continuous release of cut culms directly into the field, intermittent release via the same culm collection member, continuous release, etc. Depending on the purpose, the culm processing release of chickens to the side of the machine (already cut field side) However, it is an object of the present invention to provide a device that can selectively eliminate this problem and improve the efficiency of waste culm processing without interfering with the next reaping operation.

To explain the details of the implementation with reference to the drawings, 1 is a combine main body, 2 is a threshing device, 3 is a culm conveyance mechanism, and 4 is a rear part of the combine main body 1, the longitudinal direction of which is perpendicular to the traveling direction of the combine. This is a known circular saw blade type cutter mechanism which is arranged as shown in FIG.
A mechanism is provided for passing through and ejecting outwardly from an opening in the rear wall of the cutter mechanism.

The mechanism for collecting the culms is omitted from the drawings because it is sufficient to use a known mechanism already proposed by the applicant.

On the rear wall of the combine main body 1, on the lower side of the cutter mechanism 4, there is fixed a shaft rod 6 which is parallel to the traveling direction of the harvester main body 1 and has a length approximately twice as long as the depth of the cutter mechanism 4. .

One side end of the bottom plate of a culm collecting member 7 having an upwardly U-shaped end surface is slidably supported on the shaft rod 6 .

Reference numeral 8 denotes a guide plate for the culm, which is slidably provided on the shaft rod 6 and inserted into the shaft in a non-rotatable manner. The guide plate 9 is
A spring 12 is removably tensioned between the hole 11 of the mounting plate 10 and the hole 11 provided in the mounting plate 10.

A plurality of holes 11 are provided in the mounting plate 10, and the springs 12
By connecting one end of the spring 12 to an arbitrary hole 11, the elasticity of the spring 12 can be adjusted to be large or small, and the set amount of rotation of the culm collecting member 7 depending on the amount of culm collecting can be arbitrarily adjusted.

An auxiliary culm collecting member 7' whose end face shape is the same as that of the culm collecting member 70 is movably provided at the pivot end of the culm collecting member 70 which has been cut.

That is, horizontal guide holes 14 are provided in the front end upright edge 13 of the auxiliary culm collecting member 7' and the guide plate γ, respectively, and the tightening screws 16 provided in the front end upright edge 15 of the culm collecting member 7 and the guide plate 9 are provided in these.
The auxiliary culm collecting member 7' can be inserted and removed as necessary.

In the figure, reference numeral 17 denotes a control piece with the lower end of the guiding plate 8 inclined in the direction of the tap root of the collecting culm member 7, which limits the downward rotation of the collecting culm member 7, and also allows one end of the spring 12 to be attached to the mounting member 7. Board 10
The culm collecting member 7 is maintained in a state in which it is rotated downward by a certain angle when it is detached from the culm member 7.

Although not particularly shown, the combine main body 1 of the culm collecting member 7
It is also possible to reverse the discharge direction of the culm by rotating the culm collecting member, shaft rod, etc. by 180° horizontally so as to switch the shaft fulcrum to the culm from the left end to the right end as viewed in the figure.

In addition, as shown in Fig. 2, the tip of the culm collecting member 7 (in case there is no auxiliary culm member) or the tip of the auxiliary culm collecting member 7' is perpendicular to the ground when it rotates downward. By fixing or removably attaching an upwardly U-shaped frame 18, and providing outward protrusions 19 at a part of the rear corner of this frame 18, the culm collection member 7 or the auxiliary Even if the distance between the rotating end and the ground when the culm collection member 7' rotates downward is greater than the length of the culm, the frame 1
The upper part of the culm is supported by the culm 8 and the protruding piece 19, and the culm can be tilted down as described later.

Next, to explain the processing of the waste culm, the harvested rice etc. is automatically and continuously adjusted by the threshing device 2 of the combine main body 1, and the waste culm is transferred to the combine harvester by the conveying mechanism 3 as shown in Fig. 4. The culm is transported to the rear of the main body 1 so that the direction of the culm is orthogonal to the direction of movement of the combine harvester.

The transported culms are sequentially fed into the cutter mechanism 4 in the form of 1\.

When the cutter mechanism 4 is in the state shown by the solid line in Fig. 1 and the culm is cut, the culm is cut into pieces.
It falls into the X field.

When the cutter mechanism 4 is switched to the culm collecting action as shown in FIG. Rotate downward around the center and leave the shed culm bundle in the field.

In this case, when the auxiliary culm collection member 7' is fully extended and the distance between the lower end and the ground when it is rotated is greater than the length of the culm, the culm bundle is placed in the state shown in A in FIG. 4, Further, when the auxiliary culm collection member T is not projected at all under the above-mentioned conditions, the state shown in FIG. 4B is reached.

Also, under the above conditions, the culm collecting member 7″!, or the auxiliary culm collecting member 7
If the distance between the lower end and the ground when rotating ' is smaller than the length of the culm, even if the culm touches the ground, its upper part is leaning against the collecting culm member or the auxiliary collecting member, and the combine main body 1 As the culm progresses, the upper part of the culm moves towards the guide plate 9 or γ
The culm is peeled off as shown in Fig. 4C in order to be lopped off.

Further, one end of the spring 12 was removed from the mounting plate 10 to free the collecting member 7, and by locking its bottom plate onto the control piece 17, the collecting member I was rotated downward by a certain angle. If this state is maintained and the culm collecting action is performed in this state, the culm will not be collected and the culm will become A, Bt or C in Fig. 4.
He is forced to remain in this position continuously.

Next, if the culm collecting member 7 is placed in the state shown by the imaginary line in Figure 1, the shredded culm will be accumulated on the culm collecting member 7 when cutting the culm, and as above, if the set weight is exceeded, the culm will be shredded. are placed in a mountain shape on the field.

Further, by canceling the automatic return action of the spring 12 of the culm collecting member 7 and keeping the culm collecting member 7 in a downwardly inclined state at all times, the cutting frame is continuously left sideways to the side of the combine main body 1.

Furthermore, when the culm collecting member 7 is moved to the imaginary line position in FIG. 1 and a culm collecting action is applied to the cutter mechanism 4, the culm is continuously cut and left alone.

In addition, in accordance with the state shown by the solid line in Figure 1, when the distance between the downward rotating end of the collecting culm member 7° and the auxiliary collecting member 7' and the ground is greater than the length of the culm, the ejecting occurs as shown in Fig. 4 C. When it is desired to leave the culm alone, by attaching the frame 18 as shown in FIG. 2, the above conditions can be reversed and the culm can be left in its original position.

In this way, by disposing the culm collecting member removably under the cutter mechanism that has a culm collecting function, it is possible to perform a wide variety of abandoned culm treatments as described above with a single machine, and it is possible to remove the culm from the field. Desired culm treatment can be performed selectively depending on the conditions and purpose of culm treatment.Furthermore, all of the various types of culm treatment are carried out on the side of the machine, on the side of the harvested land, so that uncut culm treatment can be carried out selectively. It has excellent features such as improved workability as there is no need for waste straw to fall on top of the culm, and there is no need for the combine crawler to step on the treated waste culm during the next harvest.
