Description

[Detailed description of the invention] The present invention provides a waste straw tying device that ties the threshed waste straw in a horizontal position and releases it rearward, and also brings the tips of the waste straw into contact when the bundled waste straw is released. The present invention relates to a combine harvester with a waste straw binding device, which is provided with a discharge position regulating rod for changing the discharge position.

Looking at the bundling process using this type of combine harvester equipped with a waste straw bundling device, it is found that during the bundling operation, there is a strong tendency for the waste straw to spread, especially in order to prevent disturbances in the collecting posture of the waste straw, which may lead to poor bundling or bundling errors. It is desirable to receive and support the waste straw in a manner that suppresses the spreading of the tip part, and when releasing the straw after bundling, the tip side of the bundled waste straw is brought into strong contact with the regulating rod to achieve the desired It is desired that the release action be performed while the posture is reliably changed.

The purpose of the present invention is to make it possible to satisfy both of the above-mentioned demands in the bundling process through simple processing improvements to the discharge position regulating rod. In the above-mentioned discharge position regulating rod, the opposing rod portion of the rod which is attached to the base side of the approximately U-shaped tip of the rod is crossed in an X shape, and the discharge position regulating rod is When the rod is tied, the cross portion can receive and support the tip of the waste straw, and when releasing the waste straw, the tip of the waste straw overcomes the elasticity of the cross portion and passes through the cross portion, and the tip of the waste straw passes through the cross portion. is characterized in that it is constituted by an elastic rod which imparts an elastic force sufficient to make contact with the abutting rod portion.

As a result, during the bundling operation, the tip of the waste straw can be reliably received and supported by the cross portion of the discharge position regulating rod, and the tip of the waste straw can be released from the predetermined bundling action position. It does not pass directly to the exit side, prevents disturbances in the collecting posture of the discarded straw caused by such passing movement of the tip, and enables reliable and good bundling without bundling defects or bundling errors. can.

However, when releasing straw, the cross section is easily opened by the moving force of the tip of the waste straw, and while the movement of the waste straw toward the culm is prevented, the straw passes through this cross section. Since the tip of the waste straw can be brought into strong contact with the above-mentioned abutting rod part, the original function of this regulating rod to change the bundled straw posture can be ensured, and therefore, it is possible to easily use only one regulating rod. The structure is such that the waste straw to be bundled is received and supported in a good posture, and it is now possible to reliably discharge the straw in a desired posture.

Therefore, by constructing the ejection position regulating rod from an elastic rod to which a predetermined elastic force is applied, and by simply improving the processing by crossing the opposing rod portions in an It has now been possible to satisfy two demands at the same time.

Embodiments of the present invention will be described below based on the drawings.

The drawing shows the main parts of the combine harvester, from the end of the feed chain 1A of the threshing device 1 to the back and lower rear of the conveyance end of the straw removal chain 2, which is installed diagonally toward the inside and rear of the machine. The waste straw tying device 3, which ties and discharges the waste straw sent out in a horizontal position in fixed quantities, is connected to a knotting mechanism section 3A consisting of a building, a string holder, etc., a tying string supply needle, a raking packer, etc. The binding mechanism parts 3B are disposed facing each other on both upper and lower sides of the binding space 3C.

In such a combine harvester, the straw removal chain 2
The conveyance guide plate 4 provided along the lower side of the waste straw conveyance path A from the conveyance terminal end to the binding space 3C of the binding device 3 corresponds to the point where the tip of the waste straw passes, and the binding device 3 corresponding thereto. A substantially U-shaped discharge posture regulating rod that changes the discharge posture to a posture along the direction of movement of the machine by bringing the tip of the bundled waste straw into contact with the knotting mechanism section 3A when the bundled waste straw is discharged. 5 is installed in such a manner that its substantially U-shaped tip abutting rod portion 5A is installed at a position rearward and outward from the base, and the conveyance guide plate 4 is provided with the waste straw at a portion corresponding to the stock base portion. The stock alignment plate 6, which aligns the stock end positions of the waste straw sent out from the chain 2 by sliding it in contact with the stock ends, is installed within the range of the elongated hole 7 formed in the conveyance guide plate 4 to adjust the length of the waste straw culm. It is installed so that its position can be changed and fixed in any direction.

The ejection posture regulating rod 5 is made of an elastic rod, and
To install it, the opposing rod parts 5B, 5B on the base side of the contact rod part 5A are crossed in an X shape at a location corresponding to the bundling action position of the waste straw, and during the bundling action, the cross part 5C is used. The tips of the waste straw are received and supported, and at the time of discharge, the discharge posture regulating rod 5 is elastically deformed from a crossed state to a U-shaped state, and the tips of the removed straw are passed through the cross section 5C to bring the tips of the removed straw into contact as described above. It is configured to come into contact with the working rod portion 5A.

Moreover, at the end of the bundled waste straw discharge port side of the stock alignment plate 6,
A stock head receiving tool 8 having an L-shaped cross section and having a first receiving part 8A that receives the stock stock part from below and a second receiving part 8B that receives the stock bundle part from the direction of releasing the bundled waste straw is used to receive the stock stock part. In the operating position, the receiving surface 8b of the second receiving portion 8B is oriented at an obtuse angle with respect to the operating surface 6a of the stock base alignment plate 6, and the stock base aligning plate 6 is swingably mounted via the hinge 9. A spring 10 is interposed between the second receiving portion 8B of the receiving tool 8 and the stock alignment plate 6, and the spring 10 biases the stock receiving tool 8 to the above-mentioned receiving action posture. The stock head catcher 8 is configured to be rotated away from its receiving action posture against the biasing force of the spring 10 as the bundled straw is discharged.

Further, a member 11 extending forward from the knotting mechanism section 3A side of the bundling device 3 along the upper side of the waste straw transport path A includes:
a first stock head presser rod 12A made of a leaf spring that suppresses disturbance of the waste straw stock head portion transferred along the waste straw transport path A;
A second stock head presser rod 12B made of a leaf spring is attached to suppress disturbance of the waste straw stock base collected in the bundling space 3C.
