Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mowing device for mowing grain culms, and feeding the mowed grain culm to a threshing device on the rear side in the traveling direction of the machine body. The present invention relates to a combine pre-mowing pretreatment device that includes a supply / conveyance device and is capable of moving the mowing device laterally with respect to the machine body. In a combine harvesting pretreatment device of this type, when the harvesting device is laterally moved in accordance with a change in the harvesting form such as a swivel cutting operation and a middle cutting operation, it is accompanied by this. Therefore, it is also necessary to change the position of the feeding / conveying device located between the harvesting device and the threshing device to transport the harvested culm to the threshing device side. As a means for changing the positions of the reaping device and the feeding / conveying device to the left and right in this way, it is conceivable to artificially adjust the position of each of them. In addition, Tokubo Sho 5
As shown in Japanese Patent Laid-Open No. 3-27171, the front end side of the support body is horizontally swung by using the rear end side of the support body supporting the harvesting device as a fulcrum to laterally move the entire harvesting device left and right. Further, there is known a structure in which the rear end portion of the supply / conveyance device is integrally attached to a support body, and the start end side position thereof is changed in accordance with a change in the orientation of the support body. [0003] However, the above-mentioned conventional structure has the following problems. In other words, as in the former, in which the position of the reaper and the supply / transport device are artificially changed individually, the supply / conveyance device is not only irrespective of the lateral movement of the reaper, but also bothersome to perform the operation of changing each of them by an appropriate amount. However, there is a problem that inconveniences such as changing the position or forgetting to return the position are likely to occur. Like the latter, the rear end portion of the feeding and conveying device is integrally attached to the support body, and the starting end of the feeding and conveying device is changed in accordance with the change in the direction of the support body that is swung left and right for the lateral movement of the cutting device. With a structure in which the side position also changes to the left and right, it is advantageous in that the position of the starting end portion of the feeding and conveying device as described above can be interlocked without forgetting to change or forget to return. Not at all. When an attempt is made to interlock the support body which swings left and right in this way and the feeding and conveying device, the support body is also swung in the vertical direction for adjusting the cutting height. Swing itself to the left and right around the rear fulcrum axis,
In order to allow the vertical movement of the supply and conveyance device for adjusting the handling depth, which is a necessary function in the combine, and to interlock it, the interlocking structure for changing the position of the supply and conveyance device and the related position before and after the change is complicated. There is a problem such as becoming, and it is not rational. It is indispensable for the combine to ensure the functions of the left and right swing and the up and down swing of the feeding and conveying device, and what should be done in this regard in relation to moving the reaping device in the lateral direction. How to move the mowing device to the left and right lateral direction while maintaining the performance of the feeding and conveying device. Reasonable solution to various problems with moving the mowing device to the lateral direction. Means are not shown. The present invention has been made in view of these points, and laterally moves the reaping device in the lateral direction with respect to the traveling direction of the machine body, and lateral movement of the feeding and conveying device with respect to lateral movement of the reaping device. It is intended to provide a rational means of how to perform vertical swing for adjusting the handling depth. Thereby, for example, when the uncut culm is positioned on the left side to perform the counterclockwise cutting operation, the left side of the reaper is protruded to the left outside of the fuselage and the uncut culm and the left By increasing the distance from the crawler traveling device, it is possible to prevent the uncut grass culm from being pushed down by the mud extruded by the left crawler traveling device or to prevent the mud from adhering to the uncut grain culm. In the case of performing the middle splitting work by positioning the cut culm on the left and right sides, by positioning the cutting device on the left and right central side of the body and positioning the weeding tool in front of the crawler traveling device on the left and right sides, An object of the present invention is to realize a combine pre-cutting pretreatment device capable of preventing an uncut culm from being pushed down and performing an effective round cutting operation and an intermediate cutting operation. According to the technical means of the present invention, which has been taken to achieve the above object, a mowing device is arranged in front of a threshing device mounted on a machine body, and the mowing device and the threshing device are arranged. The feeding and conveying device is installed so as to be swingable left and right around the axis of the rear fulcrum shaft provided inside the threshing feed chain starting end portion on the conveying end side thereof, and the mowing device is moved after the mowing device. Is a combine pre-mowing pretreatment device capable of moving laterally with respect to the body side so as to maintain a posture substantially orthogonal to the body traveling direction as before the movement, wherein the feeding and conveying device is , The rear horizontal fulcrum axis along the left-right lateral direction at the end point of the conveyance, and the rear vertical fulcrum shaft along the vertical direction at the end point of the conveyance, the conveyance start end side is moved vertically and horizontally around the axis of each fulcrum shaft. It is configured to swing freely In addition, the supply transport device and the mowing device are interlocked and coupled via a connecting mechanism so that the starting end side of the supply transport device follows and moves with the lateral movement of the mowing device, and the connecting mechanism is , Allowing the circular movement of the feed conveying device starting end portion that accompanies the lateral movement of the reaper, restricts the relative movement in the left-right direction, and causes the supply conveying device starting end portion caused by the vertical movement. That is, it is configured to have a structure that allows circular arc movement. The connecting mechanism restricts relative movement in the left-right direction by inserting the rod and a rod that bends forward so as to allow an arc motion of the starting end portion of the feeding and conveying device caused by movement in the vertical direction,
In addition, it may be configured with a long hole that allows movement in the front-rear direction. The rod of the connecting mechanism may be set to have a length that covers the vertical swing range of the starting end portion of the feeding and conveying device.
It is preferable that the supply / conveyance device be configured so that the handling depth can be adjusted by changing the vertical position on the transport start end side by controlling the handling depth. The operation of adopting the above configuration is as follows. That is, the connecting mechanism for moving the starting end side of the feeding / conveying device in accordance with the lateral movement of the reaper is allowed to allow the arc movement of the starting end portion of the feeding / conveying device caused by the lateral movement. , A structure that restricts relative movement in the left-right direction and allows an arc motion of the starting end portion of the supply / transport device caused by the movement in the up-down direction, and allows the supply / transport device to move to the left / right and left / right by allowing the front-end position change Since it is configured to be movable in the vertical direction, the horizontal movement of the mowing device in the lateral direction and the lateral movement of the feeding and conveying device on the starting end side around the rear fulcrum axis are accurately performed as the mowing device moves in the lateral direction.

When the rod is bent forward and the member having the long hole for inserting the rod is used, the entire connecting mechanism can be configured with a simple structure and the above-described action can be achieved. In addition, by constructing the bar that bends forward to a length that spans the vertical swing range of the starting end of the feeding / conveying device, the feeding / conveying device can be moved laterally to the left or right regardless of the position of its starting end. It is convenient because it can be followed and moved. [0006] The effect of adopting the above configuration is as follows. That is, as a connecting mechanism for following the starting end side of the feeding and conveying device along with the lateral movement of the reaping device, it allows an arc movement of the starting end portion of the feeding and carrying device caused by the following movement in the lateral direction. Together with a structure that restricts the relative movement in the left-right direction and allows the arc movement of the feed transport device starting end portion caused by the movement in the up-down direction, allowing the feed transport device to change the front-back position of its starting end, Since a mechanism that allows horizontal and vertical movement is adopted, the starting end side of the feeding and conveying device is accurately followed along with the lateral movement of the mowing device, and before and after the lateral movement of the mowing device. It is possible to prevent the relative position of the starting end of the feeding and conveying device in the left-right direction with respect to the reaping device from collapsing, and to keep the starting end of the feeding and conveying device in a suitable position to follow the reaping device. .
