Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a binder, combine or the like provided with a carrier for receiving culm from the binding machine side, nipping and carrying it to the already-cut area, and discharging it. The present invention relates to a device for discharging waste.

[Problems to be Solved by Prior Art and Invention] Generally, in this kind of combine, etc., threshing-treated culms are bundled by a binding machine provided at the rear of the machine body and discharged to the field. However, this is because it is necessary to prevent the released bundle from being trampled by the machine during the next work process and to facilitate the collection work of the bundle after the work. After receiving the bundle that is thrown backward, it is transported to the side of the machine that has already been cut, and from the end of the transport, the bundle has been fitted into a bundle that is substantially in line with the direction of travel of the aircraft, or a vertical bundle. It is designed to be released in the release position.

However, when this carrier is used as it is, and the culms that have not been bound are released to the field, the discharge posture of the culms discharged from the carrier does not change from the case where the bunches are bundled. It is not possible to discharge in a discharge posture substantially orthogonal to the aircraft advancing direction, which is considered to be a preferable discharge posture for culms that has not been discharged, and the actual discharge posture is disturbed and drying and recovery are smooth. In addition, there is a drawback that it cannot be done promptly, and when discharging unremoved culm there, a special discharging device must be prepared separately, which is a problem.

[Means for Solving the Problem] The present invention was conceived with the object of providing a device for discharging culm in a combine or the like, which can eliminate these drawbacks in view of the above-mentioned circumstances. In a combine or the like that is provided with a carrier for receiving culm from the machine side and sandwiching and carrying it to the already-cut area of the machine body and discharging it to the field, change the discharging posture of the carrier to the culm A deformable action posture that gives resistance as much as possible and a deformable non-deformation posture in which the discharge posture is not transformed are provided, and the deformable action is performed when the transport culm is a binding bundle. It is characterized in that it is connected to a switching means for switching to a posture and for switching to a non-transforming posture when it is not a bunch.

With this configuration, the present invention makes the unwinding culms unbound from the transport body that transports the untied bunches to the already-cut area by changing the releasing attitude from that of the untied bunches. It is designed to have a preferable posture corresponding to culmination.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings. First, in the first embodiment shown in FIGS. 1 to 7, 1 is a binding machine provided at the rear part of the combine body, and the binding machine 1 is threshed by a threshing unit (not shown). In addition, the culms that are sandwiched and conveyed by the culm conveyer 2 are bound together by a predetermined amount, and for that purpose, the knot portion 3, the needle 4, the packer 5, the door 6, the sweeper 8
Etc. are configured as usual, and
At the rear of the binding machine 1, there is provided a carrier 9 that receives the binding bundle thrown rearward by the sweeper 8 of the binding machine 1 and conveys it to the diagonally rearward cut grass side. The carrier 9 is composed of a carrier chain 10, a carrier rail 11, a support member 12 that elastically supports the carrier rail 11, and the like.

In the binding machine 1, the base end of the link 13 is pivotally connected to the actuating arm 6a protruding from the base end of the door 6. On the other hand, 14 is a clutch shaft of the binding machine 1, and a clutch arm 15 is integrally mounted on the clutch shaft 14. The clutch arm 15 has the link 1
The tip portion 13a or the intermediate portion 13b of No. 3 can be selectively connected.

That is, when the tip portion 13a of the link 13 is connected to the clutch arm 15 as shown in FIG. 6, the clutch arm 15 and the door 6 swing together through the link 13, and therefore the door When 6 collapses due to the pressing force of the collected culms by the packer 5, the clutch arm 15 also swings, whereby the clutch mechanism operates, and after the gathering of the collected culms is performed. The sweeping operation of the bundling bundle is performed by the sweeper 8 at the same timing. On the other hand, when the intermediate portion 13b of the link 13 is connected to the clutch arm 15 as shown in FIG. 7, the door 6 is maintained in a lying posture, and in this case, the packer 5 collects the culm of the drainage. Even if
The culms are transported to the rear side over the door 6 as they are and are supplied to the carrier 9 side.

Reference numeral 16 denotes a support member 12 of the carrier 9 whose base end is a pivot 12
A resistor pivotally mounted about a as a fulcrum,
One end 17a of the inner wire 17 is connected to the actuating piece 16a that is formed by projecting at the base end of the resistor 16.
The other end 17b of the inner wire 17 is connected to the operating arm 6a of the door 6. Further, the outer holders 18 and 18a for the inner wire 17 are provided in the clutch arm 15
And the support member 12. As described above, when the link tip portion 13a is connected to the clutch arm 15, the other end portion 17b of the inner wire 17 and the outer receiver 18 corresponding to the other end portion 17b are in a pulled state and are largely separated from each other. In this state, the resistor 16 is in the deformed non-acting posture, which is located above and away from the transport path of the culm in the carrier 9, and may come into contact with the culms that are nipped and carried. It is set not to. On the other hand, when the link middle portion 13b is connected to the clutch arm 15, the distance between the other end portion 17b of the inner wire and the outer receiver 18 becomes K (K <L), which means that the inner wire 17 is delivered. Resistor 16
Receives the urging force of the tension ammunition machine 19 and moves downward to be in a deformed working posture, whereby the resistor 16 contacts the stock side of the culm that is nipped and conveyed by the carrier 9 to exert resistance. The posture of the feeding and drainage is transformed so as to be substantially orthogonal to the traveling direction of the machine body, and is discharged to the field.

In the first embodiment of the present invention constructed as described above, in order to discharge the culms as a bundle into the field, the link tip 1
It suffices to operate the binding machine 1 with 3a connected to the clutch arm 15. In this state, as described above, the door 6 responds to the fact that the door 6 falls due to the pressing force of the culm collected by the packer 5. Then, the bundling operation of the collected culm and the subsequent release operation of the bundling bundle by the sweeper 8 are performed. Then, the released bundles are caught by the carrier 9 and transported to the slaughtered land side so that the stocker side is largely swung backward and the culm direction is oriented substantially forward and backward, and the bundle is moved in the traveling direction of the machine body. It will be discharged to the field in a substantially straight line-like discharging posture. In this case, the resistor 16 is switched to the upper non-deformation posture by the pulling action of the inner wire 17 as described above, so that the discharging posture may be disturbed by coming into contact with the binding bundle that is nipped and conveyed. There is no.

On the other hand, if it is desired to discharge the culms without bundling them, connecting the link intermediate portion 13b to the clutch arm 15 leaves the door 6 lying down. As a result, the culms gather in front of the door 6. It is sent to the rear as it is without being culled, and is nipped and carried by the carrier 9 toward the already-cut area. However, in this case, the resistor 16 that has received the feeding action of the inner wire 17 by connecting the link intermediate portion 13b to the clutch arm 15 is
When receiving the urging force of 9, it moves downward and switches to the transformation action posture,
As a result, the culms are clamped and conveyed to the root side of the culms to give resistance, and as a result, the culms are discharged to the field in a posture that is substantially orthogonal to the direction of travel of the aircraft, due to the change in the conveying posture. Will be.

In this way, in the case where the present invention is implemented, when the uncoalesced culms are discharged, the carrying posture thereof is
It is possible to transform and discharge the discharged culms into a discharge posture suitable for uncoalesced culms, and thus the discharged culms can be smoothly dried and the discharged culms can be collected. Will also be easier. Moreover, the resistor 16 for changing the posture of the discharge posture is not a manual switch for each, but the posture adjustment of the door 6 for deciding whether or not to bind is a switching means and is used when binding the culms. Is changed to the non-transforming action posture, and if it is not bundled, it is automatically transformed to the transforming action posture. Therefore, there is no mistake in switching the resistor 16, and the culms are optimally adapted to the discharge state. It can be released in various postures.

On the other hand, in the second embodiment shown in FIGS. 8 to 12, the posture switching control of the resistor 16 is not performed by adjusting the posture of the door 6 as in the first embodiment, but the transfer of the culms is performed. This is done by sensing and grasping the situation.

That is, in this device, the sensing switches 20 and 21 are provided at appropriate intervals before and after the transport path in the transport chain 10, and the resistor 16 is linked to a solenoid 23 having a built-in delay timer 22. As shown in FIG. 10, when the culms that are nipped and conveyed are bundled bundles, the bundled bundles are conveyed intermittently.
Solenoid 2 because 0 and 21 do not close at the same time
3 does not operate and the resistor 16 is switched to the non-transforming posture, but as shown in FIG. 11, when the culms are continuously conveyed without being bound, both sensing switches 20 and 21.
Closed at the same time. As a result, the solenoid 23 is actuated to transform the resistor 16 into the transforming action posture, and the discharge posture is automatically switched between the bundled one and the one not bundled. You can

In the case of this one, in addition to the effect equivalent to that of the first embodiment, further, in the work of releasing the culms into a bundle and releasing the bundle, there is a case in which a binding error occurs and the bundle is not bound. , It is possible to detect this individually and discharge the culm for the binding error automatically from the bundled ones, and to discharge the culms in different postures. This is convenient because it has the advantage that it can be significantly improved.

The delay timer 22 used in this embodiment is
When discharging the unbound culm, when the continuously transported culm is interrupted or the work is interrupted, the sensing switch 20 on the starting side of the carrying is present even though it is still being carried. In this case, the operation stop of the solenoid 23 is delayed for a predetermined time so that all the culms can receive the resistance action of the resistor 16.

[Effects] In summary, since the present invention is configured as described above, it is necessary to release a culm unbound by a carrier that receives a bunching and then carries the bunches on the side of the cut land to the field. , If the culm is not bundled, it will be subjected to the resistance action by the resistor switched to the transforming action posture, and thus the discharge posture different from that in the case of binding can be obtained. When discharging unbound culm, ideal discharge of unbonded culm by effectively utilizing the bundle discharging carrier without installing a separate discharging device as in the past. Therefore, the discharged culms can be dried and recovered quickly and reliably.

Moreover, the switching of the resistors is automatically switched by the switching means based on whether or not the transport culms are bundled, and the troublesome manual switching work becomes unnecessary, and the workability is impaired. Never.
