[Problems to be Solved by Prior Art and Invention] In general, in this type of combine, the stem culm supplied from the stem culm bundling machine side is conveyed to the rear of the stalk culm bundling machine toward the rear cut land side. There is a culm conveying / discharging device configured to receive a stem culm conveyed by the conveying body, and discharge the stem culm received by the conveying body to a field when a predetermined amount of accumulated stem culm is accumulated. .

However, since this one can be installed as it is in the working posture in which the stem culm group is discharged even when it is not used,
The stem and culm transport and discharge device inevitably protrudes to the rear of the machine, and the front-rear length of the machine becomes long.For this reason, it is difficult to drive when traveling up and hits people and things. However, there are drawbacks such as the necessity of occupying a large area for storage in a barn.

Therefore, a culm conveying / discharging device configured to be housed is proposed, for example, as disclosed in Japanese Utility Model Laid-Open No. 59-110539. This culm conveying / discharging device is located behind the stem / culm bundling machine. Since the device is configured to be folded and stored, although it is folded, the fact that the stalk-conveying and discharging device is present behind the stalk-and-bundle binding machine remains the same, and the above-mentioned drawbacks are eliminated. It can't be said to be bad.

[Means for Solving the Problem] The present invention was conceived with the object of providing a storage structure for a stem-culm conveying / discharging device in a combine that can eliminate these drawbacks in view of the above circumstances. Then, a carrier that conveys the stem culms bound by the stem culm bundling machine toward the rearward cut area, and the stem culms conveyed by the carrier, and the received stem culm is a predetermined amount. In a combine provided with a stem culm conveying / discharging device configured with a receiver for discharging the accumulated culm culm group to a field at a gathering place, in the combine provided in the rear of the stalk / culm bundling machine, Arranged in an inclined manner in plan view so that the side of the already-cut land is located forward, and interlockingly connected so that power transmission to the carrier is input to the front end of the inclination via a transmission intermediate shaft that faces the horizontal direction in the left and right directions. , The stem culm conveying and discharging device is a stem culm bundling machine? It is pivotally supported around the axis of the transmission intermediate shaft so as to be displaced to an action posture position for receiving the stem culms released from the stem and a storage position located below the stem culm bundling machine. It is characterized by having done.

Further, according to the present invention, according to this configuration, the stem culm discharge device can be compactly stored by effectively utilizing the space below the stem culm bundling machine, and the front-back length of the machine body when not in use can be minimized. It is designed to be small.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a stem-culm bundling machine attached to the rear part of the combine, and the stem-culm bundling machine 1 is a stem culm (thusd culm) threshed by a threshing unit (not shown) for each predetermined amount. Although it is bound in a bundle and is thrown rearward by the sweeper 1a, a carrier 2 is provided behind the stem-culm binding machine 1.
The carrier 2 is adapted to forcibly carry the stem-culm bundle thrown from the stem-culm bundling machine 1 toward the already-cut area by the rotation of the transport claw 2a as described later. A stem-culm transfer and discharge device 3 is integrally provided as a device provided with the transfer body 2.

That is, the stem-culm conveying / discharging device 3 is configured to cover the receiver 4 formed to collect the stem-culm bundle transferred from the carrier 2, and the cover body configured to cover the rear outer periphery of the receiver 4. 5 and the stem culm bundle supplied and conveyed from the conveying body 2 accumulates on the receiving body 4 by a predetermined amount, the receiving body is elastic due to the weight of the accumulated culm bundle. The stem culm transfer / discharging device 3 conveys the stem 4a of the receiving body 4 by means of the stays 3a, 3b. By being supported by the body 2, it is integrally attached and fixed to the carrier 2. In addition, 4b is an operating ammunition for a receiver.

Further, the cover body 5 is formed in a substantially doglegged shape, and a swing arm 5a is extended from the end portion on the side of the already cut ground. The base end portion of the swing arm 5a is a stem-and-bundle binding machine 1
The support shaft 6a of the bracket 6 provided on the side is pivotally supported so as to be swingable in the front-rear direction, whereby the cover body 5 and the stem-bundle bundle thrown from the above-mentioned stem-bundle binding machine 1 are received. From the working posture (solid line state of FIG. 5) to the first storage posture (state of the same two-dot broken line) located on the receiving body 4, and when the stem-culm transporting and discharging device 3 is in the storage posture as described later. It is configured so that it can be swung and transformed into a possible second storage posture (state of the same three-dot broken line). The cover body 5 positioned in each of these postures has a locking hole 5c formed in the collar portion 5b provided on the swing arm 5a.
Can be held in the corresponding postures by pinning 5b in accordance with the positioning holes 6b corresponding to the postures provided in the bracket 6.

On the other hand, a plurality of the conveying claws 2a of the conveying body 2 are integrally projected on the operating shaft 7, and the rotation of the operating shaft 7 is used to forcibly feed the stalk bundle. But the operating shaft 7
The bevel gear 7a axially attached to the base end of the bevel gear 7a is attached to the stem-cutter bundling so that the tip end side provided with the transfer claw 2a is located rearward of the uncut area of the machine body. It meshes with a bevel gear 8a provided on an intermediate shaft 8 (the axis of which is horizontally oriented in the horizontal direction) which is power-transmitted from the machine 1 side, whereby the carrier 2 drives the driving force from the engine side. In response to this, the stem culm bundle is forcibly fed.

Reference numeral 9 is a cover body that covers the intermediate shaft 8, and 10 is a case body that covers the bevel gear portion of the working shaft 7. The case body 10 on the working shaft side is removable and insertable in the axial direction of the intermediate shaft 8. The case 9 on the side of the intermediate shaft is externally fitted and supported so as to be swingable about the axis of the stem 8. By this, the stalk-carrying and discharging device 3 provided with the carrier 2 is arranged so that the stalks and bundles are rearwardly moved. It is possible to change from the action posture of forced feeding to the storage posture in which the intermediate shaft 8 is pivoted downward to be stored in the space below the stem-and-bundle binding machine 1.

Further, a fixed arm 12 is projectingly provided on a cover cylinder 11 which is integrally extended from the case body 10 so as to cover the actuating shaft 7, and a fixed member 12a provided at a tip end portion of the fixed arm 12 is a stem stem. Binding machine 1
The bracket 9a on the side faces a fixed member 9b integrally provided so as to match the shaft center of the intermediate shaft 8, and both fixing members 9b and 12a are fixed by a tightening operation of a fixing tool 13. Thus, it is possible to fix and hold the carrier 2 that has been transformed into the working posture and the storage posture.

In the figure, 14 is a cutter for shredding the stalks conveyed from the threshing section, and 14a is an outlet for discharging the shreds.

In the embodiment of the present invention constructed as described above, the stem-culm bundle ejected from the stem-culm binding machine 1 is sent to the carrier 2 by placing the stem-culm transporting and discharging device 3 in the working posture. After being transferred by the transfer body 2, the transfer body 2 is transferred to the rear side of the machine body on the side of the cut grass and received on the receiving body 4. When the stem culm bundle is stored in a predetermined amount in this way, the receiver 4 moves downward due to its weight against the operating ammunition 4a, and the accumulated stalk bundle is dropped and discharged into the field. .

In this way, the stem-culm conveying and discharging device 3 conveys the stem-culm bundle,
The culm bundle group stored in a predetermined amount is discharged.
For example, when the stalk-carrying and discharging device 3 is not used as in the case of traveling on the road and the stalk-carrying and discharging device 3 is desired to be stored, the fixing tool 13 is released and the stalk-carrying device equipped with a carrier When the discharging device 3 is pivoted downward from the working posture to the storing posture and is fixed again by the fixing tool 13, the stem-culm transport discharging device 3 is stored in the space below the stem-cullet binding machine 1. Therefore, even if the culm transporting and discharging device 3 is provided at the rear of the machine body, if it is transformed into the storage posture, it is compact in the space behind the cutter discharge port 14a, which is the space below the stalk and tying machine 1. Since it is housed in the car, the front-rear length of the machine can be shortened, which makes it easy to run on the road and poses the risk that the stalk-carrying and discharging device 3 hits a person or an object as in the past. It is possible to prevent it from occurring, and when the combine is stored in the barn, the area occupied by the combine can be reduced. Moreover, the storage of the stem and culm transport and discharge device 3 is performed by the stem and culm binding machine
The space below can be effectively used. in this case,
It is substantially preferable to keep the cover body 5 in the second storage posture.

Moreover, in this case, the stem-culm transport and discharge device 3 including the transport body 2
Since it is integrally stored as, the front-rear length can be further shortened.

Further, when the stem-culm transporting and discharging device 3 is in the storage posture,
If the cover body 5 is placed in the working position, the cover body 5 receives the stem culm bundles thrown from the stem-culm bundling machine 1 and falls downward as it is. In the case of work or the like, it is possible to prevent as much as possible a problem that the stem culm bundle is thrown far backward by the operation of the sweeper 1a and falls onto the uncut stem culm.

[Effects] In summary, since the present invention is configured as described above, the stem and shoot conveying and discharging device, which is provided at the rear of the stem and shoot bundling machine and is composed of a carrier and a receiver, is not used. If you rotate it downwards to transform it into a storage position, it will be stored compactly in the space below the stem-and-bundle binding machine.
Even if a culm-carrying and discharging device with a carrier is provided, it can be effectively stored in the lower space of the stalk-and-bundle binding machine. ,
The front-rear length of the machine can be shortened as much as possible to improve the running performance, and it is possible to reliably avoid the risk that the stalk-carrying and discharging device gets in the way and hits people and things as in the past.
When it is stored in a barn, etc., its occupied area can be reduced.

Moreover, the storage of the stalk-carrying and discharging device under the stalk-and-culm binding machine is performed by arranging the stalk-carrying and discharging device in a slanted shape in plan view so that the cut land side is located in front, and the power to the carrier is set. This is done by being pivotally supported around the axis of the transmission intermediate shaft that is horizontally oriented for transmission, so that there is no need for a member such as a link material, and the slanted stem culm is not required. The structure is not complicated because the organic coupling structure of the horizontal and horizontal transmission intermediate shafts necessary for power transmission to the transport body of the transport discharge device can be used as it is.
