DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage posture for exposing a transfer start end of a threshing feed chain for supplying a harvested grain culm conveyed from a cutting device to a threshing apparatus, and a grain culm placing action for covering the transfer start end. The present invention relates to a combine provided with a hand-carried cereal culm mounting support that can be freely switched between a posture and a posture.

[0002]

2. Description of the Related Art In a combine of this type, a harvester is supplied to a transport start end of a threshing feed chain by switching a hand-cuttered grain culm mounting support to a retracted position, thereby enabling a normal combine. The work is performed, and on the other hand, the pillow handling threshing is performed by switching the hand-cut culm placing support to the cereal placing action position. Conventionally, as shown in JP-A-8-298844. In addition, the hand-cutting culm mounting support was equipped in the threshing device.

[0003]

However, in the case of the above-mentioned conventional technique, the hand-cuttered grain culm mounting support must be attached to a position near the starting end of the threshing feed chain in the threshing device. Since the hand-cut grain culm mounting support is positioned above the transport start end and protrudes upward from the transport start end in a state positioned on the outside or inside and outside of the transport culm, the grain culm placement covers the outside or inside and outside of the transport start end. It becomes the working posture. As a result, the upper surface of the transport starting end is opened upward even in a state where the hand-cuttered grain culm placing support is switched to the grain culling placing posture, and the hand-cutter switched to the grain culling placing posture is changed. When a cereal stalk was placed on the cereal stalk placement support, there was a risk that the placed stalk would come into contact with the transport start end.

[0004] It is an object of the present invention to surely make sure that the cereals placed on the hand-carried cereal stalk-mounting support switched to the cereal stalk-mounting position are in contact with the starting end of the transported cereals. The point is that it can be prevented.

[0005]

The features, functions and effects of the first aspect of the present invention are as follows.

[Features] Switching operation between a retracted posture for exposing the transport start end of a threshing feed chain for supplying the harvested grain culm conveyed from the harvester to the threshing device and a grain culm placing action posture for covering the transport start end. A combine provided with a free-cutting culm placing support, wherein the hand-cutting culm placing support is mounted on the cutting device.

According to the first aspect of the present invention, since the hand-cut culm placing support is mounted on the mowing device, the hand-cut grain culm placing support is moved from above with respect to the transport start end portion. Further, it is possible to switch the hand-cut grain culm placing support from the retracted posture to the grain culm placing operation posture. As a result, as the hand-cut cereal culm placing support, a structure / form that covers the upper surface of the transport start end in the cereal laying operation position can be adopted, for example, an upper surface cover plate that covers the upper surface of the transport start end can be used. When the cereal stalk is placed on the hand-cut cereal stalk placing support which has been switched to the cereal stalk placing action posture by, for example, Can reliably cover the transport start end.

[Effects] Therefore, according to the first aspect of the present invention, the transfer start end of the mounted cereal culm when the cereal culm is mounted on the hand-cut cereal culm mounting support switched to the cereal culm mounting operation posture. It has become possible to reliably prevent contact with parts.

According to the second aspect of the present invention, the features, actions,
The effects are as follows.

[Features] In the features of the first invention,
The hand-cuttered grain culm mounting support has an upper surface cover plate that covers the upper surface of the transport start end of the threshing feed chain in the grain laying position, and a side cover plate that covers the outer surface of the transport start end. The point is that it is.

According to the second aspect of the present invention, the upper surface of the transport start end is covered by the upper surface cover plate of the hand-cut grain culm placing support which has been switched to the grain culm placing operation posture, and the side cover plate is provided. Since the outer surface of the transport start end can be covered by the section, it is possible to prevent the contact of the cereal stalk placed on the hand-cut cereal culm mounting support with the transport start end and, of course, the hand-cut cereal culm. It is possible to prevent the worker supplying the grain stalk placed on the placement support to the entrance of the threshing device from contacting the transport start end.

[Effects] Therefore, according to the second aspect of the present invention, it is possible to improve the workability of supplying cereal stems to the threshing apparatus during threshing with pillows.

According to the third aspect of the present invention, the features, functions,
The effects are as follows.

[Features] In the features of the first and second aspects of the present invention, the hand-carried grain culm placing support is moved to the retracted position in conjunction with the operation of the cutting clutch for intermittently transmitting power to the mowing device. The present invention is characterized in that interlocking means is provided for switching the hand-carried grain culm placing support to the grain culm placing action posture in conjunction with the switching and the clutch disengagement operation of the harvesting clutch.

[Operation] In this type of combine, the harvesting device is driven and the hand-cutting grain culm mounting support is switched to the retracted position to perform the combine operation. On the other hand, the cutting device is stopped and the hand-cutting grain culm loading is performed. A mode in which the pillow handling threshing is performed by switching the placing support to the grain stalk placing action posture is adopted. Focusing on the above points, when according to the third aspect of the present invention, the interlocking means is provided, and the hand-carried grain culm mounting support is switched to the retracted posture in interlocking with the engagement operation of the cutting clutch for the combine operation, The hand-cuttered grain culm placing support is switched to the grain limb placing action position in conjunction with the cutting operation of the cutting clutch for throwing and threshing. In some cases, switching of the hand-cut cereal stalk placing support can be automated so as to switch to the cereal stalk placing action posture at times.

[Effect] Therefore, according to the third aspect of the present invention, operability is improved without requiring any special operation, and the hands are cut into the retracted posture during the combine operation and into the cereal stalk placing operation posture during the pillow threshing. It has become possible to switch the support for placing the culm.

According to the fourth aspect of the present invention, the features, functions,
The effects are as follows.

[Features] In the features of the first, second, and third aspects of the present invention, the hand-cuttered grain culm mounting support is provided in a storage posture, in which the grain culm transport unit is transported to the threshing feed chain of the reaper. Is located below the dust-proof cover that covers the upper part.

[Operation] According to the fourth aspect of the present invention, the hand-carried grain culm mounting support is located below the dust-proof cover with the switching to the storage position, so that the hand-cut grain culm mounting support in the storage position is provided. Can be covered with a dustproof cover.

[Effects] Therefore, according to the fourth aspect of the present invention, it is possible to cover the upper part of the hand-cut grain culm mounting support in the retracted posture without providing a special cover, that is, with a simple structure.
