Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine harvester in which a mowing device for mowing a culm is supported so as to be movable left and right and laterally with respect to an airframe equipped with a threshing device. It relates to a pretreatment device. 2. Description of the Related Art In this type of combine pre-processing device, the harvesting device is moved laterally left and right in accordance with a change in a cutting mode such as a round cutting operation and a middle cutting operation. In addition, it is necessary to change the position of the supply / transportation device that is located between the cutting device and the threshing device and that conveys the cutting stem to the threshing device side. In order to change the positions of the reaper and the supply / transport device to the left and right in this manner, conventionally, the positions of the reaper and the supply / conveyance device are adjusted individually or individually, or
As shown in Japanese Patent No. 171, by swinging the front end side of the support to the left and right with the rear end side of the support supporting the reaper as a fulcrum, the entire reaper is laterally moved left and right, and It is known that a rear end portion of a supply / conveyance device is integrally attached to a support, and a start end side position of the support is changed according to a change in direction of the support. [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. Also, as in the latter, the rear end of the supply / transport device is integrally attached to the support, and the direction of the support that is swung left and right for the lateral movement of the reaper is changed. Is advantageous in that the position of the starting end of the supply / conveyance device can be linked without forgetting to change or return, as described above. . However,
In the case where the support that swings right and left and the supply / transport device are interlocked in this way, the support is also swung up and down to adjust the cutting height. It is necessary to swing the device itself to the left and right, and furthermore, to allow the up and down swing of the supply and transport device for adjusting the handling depth, which is a necessary function in the combine,
The interlocking structure for maintaining the position change of the supply / conveyance device and the relation position before and after the change becomes complicated, which is not rational. After moving the reaper in the left and right direction, regardless of the left and right swing of the support, how to move the reaper to the left or right while maintaining the intended forward posture without changing the orientation of the reaper No solution is given as to how to do so, or how to move the reaper horizontally and horizontally without deteriorating the performance of the feeding and conveying device. The present invention has been devised in view of these points. The present invention is directed to laterally moving the reaper in the left-right lateral direction with respect to the machine body traveling direction, and in response to the lateral movement of the reaper, the lateral movement of the supply transport device. Alternatively, it is intended to provide a single rational means with a simple configuration as to 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. [0004] The technical means of the present invention taken to achieve the above object are as follows. That is, in the first invention, a mowing device is disposed in front of the threshing device mounted on the fuselage, the supply and transport device is installed between the mowing device and the threshing device so as to be able to swing left and right, and the mowing device is mounted on the machine side. In the combine harvesting pre-processing device which is capable of moving laterally with respect to the rear, the supply and transport device includes a rear lateral fulcrum axis extending in the horizontal direction at the transport end side and a vertical axis at the transport end side. The culm length is provided with a culm length sensor for detecting the culm length of the stem culm in the middle of conveyance while the conveyance start end side is provided so as to be able to swing up and down and left and right around the axis of each fulcrum shaft with the vertical fulcrum shaft. By changing the vertical position on the transport start end side based on the detection result of the culm length by the sensor, the handling depth is configured to be freely adjustable, and the supply transport device and the reaper are associated with the lateral movement of the reaper. Starting end of the feeding and transporting device A first linking mechanism that moves back and forth so as to allow the circular movement of the start end of the supply / transportation device that occurs with the following movement in the lateral direction; Articulated body and a second articulated body that regulates the relative movement of the first series of joined bodies in the left-right direction and allows the circular movement of the supply transfer device start end caused by the vertical movement by adjusting the handling depth. That is, it is constituted. According to the second aspect of the present invention, a mowing device is disposed in front of the threshing device mounted on the machine body, and a supply and transport device is installed between the mowing device and the threshing device so as to be able to swing left and right, and the mowing device is mounted on the machine body side. In a combine harvesting pre-processing device which is capable of moving laterally left and right with respect to a support which allows the mowing device to swing up and down around a horizontal fulcrum axis on the threshing device side,
A lateral movement guide device that is mounted on the support so as to be movable in the lateral direction and supports the reaper in a laterally movable manner is constituted by a pair of front and rear guide mechanisms. The first support guide body having a circular contact surface provided on the side and the first moving guide body having a circular contact surface provided on the reaping device side are fitted to each other, so that the lateral movement of the reaping device relative to the machine body side is achieved. The second guide mechanism on the front side is configured to restrict the movement in the front-rear direction and the vertical direction while allowing the second movement guide body provided on the reaper side, and the second support guide body provided on the machine body side. , Is configured to regulate the vertical movement while allowing the lateral movement of the second moving guide body, the reaping device and the supply and transport device via a connecting mechanism,
The supply transport device is configured so that the start end side thereof follows the lateral movement of the reaper, and the connecting mechanism is moved back and forth so as to allow a circular motion of the supply transport device start end portion caused by the lateral follow-up movement. That is, it has a structure to move to. The operation of the above-described technical means is as follows. According to the configuration of the first invention, the connecting mechanism for following the starting end side of the supply / transport device with the lateral movement of the mowing device is provided at the start of the supply / transport device with the following movement in the lateral direction. A first connecting member that moves back and forth so as to allow an arc movement of the first connecting member, and a starting point of the supply transfer device that is restricted by the relative movement of the first connecting member in the left-right direction and is caused by the vertical movement by adjusting the handling depth. With the second connecting body that allows the circular motion of the section, with the lateral movement of the reaping device, the starting end of the supply and transport device follows, the left and right relationship position with the reaping device. The swinging of the supply transport device start end portion with respect to the reaping device in the lateral direction with respect to the reaping device can be moved corresponding to the movement of the reaping device. Further, in the harvesting operation after the movement, it is possible to vertically swing the starting end of the supply / transportation device for adjusting the handling depth while maintaining the left / right relationship position with the harvester. According to the configuration of the second invention, the lateral movement guide device that supports the mowing device so as to be able to move left and right with respect to the machine side is stably supported by the pair of front and rear guide mechanisms, and the first guide on the rear side. Since the mechanism is configured to be movable in a state where the first moving guide body on the reaping device side is fitted to the first support guide body on the body side, the reaping device accurately positions its front and rear and up and down directions. Maintained, the guide body smoothly moves along the axis of the guide body, and the forward posture of the mowing device can be maintained as expected regardless of its lateral movement. In addition, the second guide mechanism on the front side, the second moving guide body provided on the mowing device side, and the second support guide body provided on the machine body side, while allowing the guide to move left and right, its vertical movement Therefore, it is possible to provide flexibility in assembling the movable guide body and the support guide body on the second guide mechanism side. In other words, when a guide mechanism having a fitting structure similar to that of the first guide mechanism is employed for the second guide mechanism, it is necessary to perform processing and assembly in a state where the parallelism between the two guide mechanisms is strictly maintained. There is
In addition, durability and the like are required so that the parallelism is maintained even when used for a long period of time. , The vertical movement of the mowing device due to the unevenness of the field or the like is prevented, thereby preventing damage and twisting of components and the like, and the lateral movement can be performed without any trouble. Then, the lateral movement of the supply transfer device start end associated with the lateral movement of the reaper causes the reaper and the supply transfer device to allow a circular movement of the supply transfer device start end caused by the lateral follow-up movement. The first guide mechanism and the second guide mechanism smooth the linear lateral movement, so that the mowing device is intended to move in the machine lateral width direction. In addition to being able to move laterally while maintaining the forward posture, the feeding and conveying device can accurately follow the lateral movement of the reaper, and switching to change the reaping mode, such as switching from rotation to intermediate cutting, is easy. The mowing device can be moved in a state where the mowing can be performed smoothly and the inconvenience of changing the direction of the mowing blade is not caused, and the mowing of the grain stalk and the supply and transport of the culm are well maintained. The effects of adopting the above configuration are as follows.

In this way, the relative position of the starting portion of the supply / transportation device in the left-right direction with respect to the reaping device before and after the lateral movement of the reaper is regulated, and the starting end of the supply / transportation device is maintained at a position suitable for the reaping device. Can be moved to follow. Then, in a state where the preferred position is maintained, the handling depth can be adjusted by vertically moving the starting end of the supply / transportation device based on the detection result of the culm length. As a result, it is possible to simplify the linkage structure between the reaper and the supply / transportation device with respect to the left / right lateral movement, and to accurately move the supply / conveyance start end portion in the left / right direction and up / down. The transfer of the grain culm to the transfer device can be performed smoothly without any support, and the culm length sensor can accurately detect the culm length to perform favorable supply and transfer. In addition, the second
