Description

[Detailed description of the invention] (a) Field of industrial application The present invention relates to a binding machine that uses a main door and an auxiliary door to catch culms that are collected in a horizontal position.

(B) Prior Art Conventionally, a binding machine is already known that holds an auxiliary door in an upright position on the stock side of the main door to catch the collected culms.

(c) In the known bundling machine, one end of the bullet that supported the auxiliary door was locked to the auxiliary door, and the other end was locked to a fixed member in the vicinity of the auxiliary door. When the bullet is pushed down by a bullet, the upright biasing force of the bullet gradually increases as the bullet falls, so if the bullet is made stronger, the separation of the bundles becomes difficult and the bundles in front and behind may become connected. In order to solve this problem, the bullet machine was weakened, and when the pack car compressed the focused culm during focusing, the auxiliary door was pushed down and the base side of the focused culm sagged, making the roots difficult to align. Another problem arose.

(d) Means for solving the problem The present invention is a binding machine in which an auxiliary door is supported in an upright position on the stock side of the main door, and one end of the ammunition that supports the auxiliary door is connected to the auxiliary door. By locking the other end to a receiving member protruding from the door shaft on the same side as the main door, the spring force that biases the auxiliary door to stand up can be strengthened to prevent the base of the stock from sagging, and also to prevent the stock from sagging. The above-mentioned problem was solved by making the ammunition weaken in response to the rotation of the main door during release.

(e) Function The culms moving toward the culm collection section are intermittently scraped into the culm collection section in front of the main door and auxiliary door by the packer and collected.

At that time, the force that urges the auxiliary door to stand up is strengthened to prevent it from tilting backwards, thereby preventing the base of the plant from sagging, and when the culms gathered in a predetermined amount are bundled and released, the main door is released. When the ammunition is laid down to the side, the locking part of the bullet also moves in the same direction, weakening the bullet. Even if the bullet is strengthened, the auxiliary door's lodging resistance is reduced, making it possible to improve the separation of bundles. .

(F) Embodiment To explain an embodiment of the present invention about a combine harvester shown in the drawings, 1 is a threshing device mounted on a machine base having a traveling device, and is installed in a dust sorting chamber at the rear of the culm. A straw removal device 2 is installed on the top plate, and a bundling device 5 is installed at the rear via a desk cutter 3.
The binding device 5 consists of a packer 8 and a needle 9 provided at the bottom of the culm collection section 7, a knot section 10 and a discharge arm 11 provided at the top, and a main door 12 provided at the rear. An auxiliary door 13 is rotatably supported on the base side of the main door 12 by a support shaft 15.

An arm 16 erected on the support shaft 15 of the auxiliary door 13 and a connecting piece 19 pivoted on an arm 18 erected from the door shaft 17 that supported the main door 12 via the support arm 14 are provided with an auxiliary A coil-shaped bullet 20 is provided to bias the door 13 upright, and one of the auxiliary doors 13 engages with a notch 22 at the rear end of a receiving guide plate 21 forming the bottom surface of the collecting culm 7. and maintains a standing posture.

In addition, in front of the arms 16 and 18 and immediately after the operating locus of the needle 9, a boss of a separating body 23 that protrudes and retracts from a long hole 24 formed in the receiving guide plate 21 onto the collecting culm part 7 is connected to the shaft 25. Pivotally supported, the separation body 23
The arm portion 23a projecting downward from the boss of the door shaft 17 and the arm 18 of the door shaft 17 are interlocked and connected by a connecting rod 26.

In the above-mentioned combine harvester, the culms that have been harvested and threshed by the combine harvester and discharged from the culm opening of the threshing device 1 are conveyed by the straw removal conveying device 2 and discharged to the rear of the desk cutter 3, and are then transferred to the binding device 5.
The culm car 8 intermittently scrapes and collects the discharged culm into the culm collection section 7 in front of the main door 12 and the auxiliary door 13, and when the main door senses that the amount of culm collection has reached a predetermined amount. Once the clutch is engaged, the needle 9 and the knot 10 are activated and knotted, and the release arm 1
1 performs bundle release while removing knots.

At that time, the auxiliary door 13 is pushed by the bundle and falls backward, but when the main door 12 tilts backward as the bundle is released, the door shaft 17 and arm 18 change from the posture shown in FIG. 1 to the position shown in FIG. As it rotates rearward as shown in , the ammunition 20 contracts.

Therefore, when the auxiliary door 13 is pushed down by the bundle, the tensile force of the ammunition is reduced and the ammunition is lowered smoothly, and unlike the conventional method, the lodging angle is small due to the large lodging resistance, making it difficult to separate the bundle. That's not going to happen.

In addition, as mentioned above, the bullet 20 becomes weak when releasing the bundle, so it is possible to construct it with a strong material. When pressed, the culms do not fall off, and the roots can be bundled in a well-aligned state.

Furthermore, when the arm 18 tilts backward following the main door 12 during the release of the bundle, the separator 23 is moved through the connecting rod 26.
As shown in FIG. 2, the needle 9 rises and protrudes immediately after it has advanced, thereby receiving the succeeding culms, and the culms being bundled and released can be clearly separated from the culms to be bundled next.

Next, the driving device for the root leveling plate 30 will be explained with reference to FIGS. 5 and 6. The support shaft 31 of the root leveling plate 30 is rotatable by a holding cylinder 33 welded to the lower rear part of the receiving guide plate 21 via a stay 32. A horizontal arm 34 protruding from the support shaft 31 is supported by a rod 35.
The middle part is connected to the upper end of the vertical swinging link 36 which is pivotally supported by a fulcrum shaft 36a, and the lower end of the swinging link 36 is placed at an eccentric position of a gear 37 which is pivotally supported on the side surface of the desk cutter 3. The gear 37 is engaged with the gear 40 of the rotary blade shaft 39, and the rotary blade shaft 39 is interlocked with an input shaft 41 driven by an appropriate shaft of the threshing device 1 via a chain 42. be.

43 is a cover, and 45 and 46 are frames made of pipes.

When the gear 37 rotates, the rod 3
8 and 35 move back and forth via the swing link 36, the root leveling plate 30 strikes the root end of the culm that is focused around the support shaft 31 to align the roots.

In this method, the driving device for the root leveling board 30 is provided in the space below the culm passage, so it does not become an obstacle to culm transport compared to the conventional method in which it is provided above.

Further, a string basket 47 is provided at the rear lower part of the desk cutter 3, and this string basket 47 has a main body 48 whose rear part is fixed to a frame 46 and whose front part is fixed to the cutter rear wall 3a, and a string brake 49. and an inner receiving plate 50 equipped with a slack remover 49a.
an elastic cover 52 whose front part is screwed to the cutter rear wall 3a and has a hook 51 on the rear upper surface; Stopper 5 made of elastic rod
5, and when attaching the string ball 56, the stopper 55 is rotated backward, and since the elastic cover 52 is approximately horizontal due to its own restoring force, the string ball 56 is attached to the main body from the rear. 48, press the rear part of the elastic cover 52 against the string ball 56, bend it as shown in FIGS. into the groove 58 of the inner receiving plate 50.

In this state, the string ball 56 is held elastically by the elastic cover 52, so it will not fall off even if the machine body vibrates, and the string that is pulled out due to rotation may become tangled and cause a bundling error. Since the string ball 56 and the string brake 49 are covered by the elastic cover 52, straw debris does not accumulate on them or rainwater splashes on them.

(g) Effects of the invention As described above, the present invention is a binding machine in which the auxiliary door 13 is supported in an upright position on the stock side of the main door 12. It is locked to the door 13, and the other end is locked to a receiving member protruding from the door shaft 17 to the same side as the main door 12, so that when the main door 12 rotates to release when releasing the bundle, the door shaft The arm 18 of No. 17 also rotates in the release direction, thereby weakening the ammunition 20 holding the auxiliary door 13 in an upright position, so that the auxiliary door 13 is less likely to become an obstacle to releasing the bundle. The bundles can be released in an orderly manner without any delay on the part of the stockholder.

In addition, since the bullet 20 weakens when the bundle is released as described above, a strong one may be used, so that even if the packer repeatedly presses the culm intermittently during focusing, the culm will move backward. It does not sag and can be tied up so that the roots are well aligned.
