Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a combine knotter that binds and discharges straw discharged from a threshing device.

(B) Conventional technology In general, a combine knotter equipped with a knotter on the culm side of a threshing device binds the straw with a needle, a knot, a discharge arm, etc., when the amount of discharged straw reaches a predetermined amount. And then released.

(C) Problems to be solved by the invention The known combine knotter is normally in a state in which a certain amount of straw is collected in the culm when the machine is circulated after one step of cutting and threshing. This collected slaughtered straw moves to the stock side due to centrifugal force when the aircraft travels, and even if an auxiliary door is provided on the stock side of the door, it is collected on the end side of the culm section. The straw was slipped off as shown by the symbol X in FIG. 2 and was bound in a state in which the roots were not well aligned.

Further, when the protruding base portion is entangled with another member, the straw bundle cannot be thrown and discharged to a predetermined position.

(D) Means for solving the problems In the present invention, a knotter is attached to the culm side of the threshing device, and the stray discharged in the sideways posture is guided by the guide plate to the culm section for binding. In the combine knotter described above, a culm guide is provided on the guide plate on the base side of the culm part on the side of the base of the stock, and a culm guide for guiding the end of the basin of straw is provided. The above-mentioned problems were solved by forming the hanging part extending downward in series.

(E) Action The straw discharged through the threshing device and discharged from the culm in a sideways posture is guided by the guide plate and collected by the packer in the culm section on the front of the door. When the door detects that a predetermined amount has been reached, as in the conventional one, a one-turn clutch is inserted and the needle hangs the binding string on the gathered straw, and when the knot is knotted, the discharge arm moves the straw bundle backwards. It will be released to the existing land.

Then, when the aircraft is circulated after one step of cutting and binding, the straw collected in the culm part receives centrifugal force toward the base of the stock and inertial force toward the rear. Even if it hangs down at the base end, the hanging part of the rear end of the culm receiving guide that projects in the discharge direction receives it, so the posture of collecting straw of the straw is greatly disturbed. There is no gap, and it does not fall out.

(F) Embodiments An embodiment of the present invention will be described with reference to the combine knotter. The threshing device 1 is mounted on one side of a machine base having a traveling device, and on the other side, an operation panel and an operation panel. Parts and grain tanks are provided in that order.

Reference numeral 2 denotes a cutter detachably attached to the rear part of the threshing device, and a knotter 3 is attached to the rear part thereof. The rear part of the threshing device extends from the rear part of the outlet to the cutter 2 in plan view. A straw conveying device 5 which is biased to the side is provided, the knotter 3 is provided with a needle 7, a packer 8 and a door 10 at the lower part of the collecting part 6, and a knot part 11 and a discharging arm 12 are provided at the upper part. A guide plate 13 is provided from the upper end of the rear part of the cutter 2 to slightly above the door 10 to support and guide the straw to the culm.

Reference numeral 15 is a scraping body installed above the starting end side of the guide plate 13, 16 is an auxiliary door, and 17 is a rooting plate that swings in the culm direction of the collected culms.

On the upper surface of the guide plate 13 near the stock root side, a culm guide 18 for guiding the end of the root of the straw that is discharged and scratched by the packer 8 is provided upright. Receives and guides also the root end of the straw that is pushed further by it and pushed by the root aligning plate 17, and the terminal end of the hanging part 18a projects rearward from the rear end of the guide plate 13. Are configured. Reference numeral 20 is a culling guide that presses and guides the upper part of the bundled straw.

In the above-described combine knotter, the straw discharged from the end of the straw conveying device 5 flows down from the rear portion of the cutter 2 onto the guide plate 13, and when the scraping body 15 scratches backward, the packer 8 takes over the door 10. And scrape into the culm section 6 on the front of the auxiliary door 16,
When the door 10 senses that it has reached a predetermined amount, the one-turn clutch is engaged and the needle 7 hangs on the converged straw and supplies it to the knot portion 11, and when the knot portion 11 is knotted, the discharge arm 12 moves to the straw. The bundle is discharged to the rear cut land.

Then, when one round of mowing and threshing is completed and the aircraft is rotated, even if the collected straw receives centrifugal force in the direction of the stem and inertial force toward the rear, the root end of the stock receives the stem guide. Even if it hangs down partly, it will not project from the culm guide 18, and even if it is higher than the culm guide 18 and slides out to the stock side, it will be rooted. Matching plate
Since the 17 swings and pushes in, it is possible to align the roots of the straw bundles that are first bundled and released after the aircraft has traveled.

(G) Effect of the Invention As described above, the invention has a knotter 3 on the culm side of the threshing device 1.
In a combine knotter that is equipped with, and guides the discharged straw discharged in a sideways posture to the culm section 6 with the guide plate 13 and binds it, on the guide plate 13 on the stock side of the culm section 6, Since the culm receiving guide 18 for guiding the root end of the straw is provided, and the rear end of the culm receiving guide 18 is formed in the hanging portion 18a which extends downward while projecting from the rear end of the guide plate 13. , When the aircraft is circulated after one stroke of harvesting, if the straw collected in the culm section 6 receives centrifugal force, the straw moves toward the root side in the direction of the stem and moves backward. However, the part of the culm guide 18 along the guide plate 13 receives the end of the concentrated root of the straw and prevents it from moving to the stock side, and the culm is collected. The root end of the straw, which is focused toward the rear of the part 6 and slides backward, extends rearward from the rear end of the guide plate 13 and then extends downward. It is prevented from projecting to the stock side while being continuously received and guided by the drooping part 18a, and when binding after the aircraft travels, make sure that the stock part of the straw bundle is well aligned. It can be released, and since the root part of the bundle of straw bundles does not project,
It does not get entangled with other members, and the bundle does not fall near the machine body and the traveling device does not step on the fallen straw bundle in the next mowing process.
