Field of the Invention The present invention supports a cutting pretreatment mechanism for cutting grain culm so that it can move laterally laterally with respect to a traveling machine body equipped with a threshing device. Conveyance Grain squeezing and conveying device that holds the culm of the grain culm and transporting in cooperation with the squeezing and squeezing device The present invention relates to a combine harvesting pretreatment device in which a vertical transport device including a device is provided, and the vertical transport device is pivotally supported so as to be swingable left and right around a rear fulcrum axis in conjunction with lateral movement of the harvesting pretreatment mechanism. [0002] In this type of combine harvesting pretreatment device, the grain culms are fed from the rear end of the vertical feeding device into the threshing device. Since it is necessary to switch to a predetermined posture (for example, a sideways posture in which the tip side is located on the side opposite to the threshing feed chain), the timing for actually releasing the locking action of the upper tip side locking pawl on the transported grain culm is set. Must be strictly controlled. However, the conventional standing guides for the locking claws are attached to the side of the support frame that constitutes the tip locking transfer device (for example, Japanese Utility Model Laid-Open No. 57-117951). Therefore, when the vertical conveyance device is swung left and right around the rear fulcrum with the standing guide attached, the standing guide also swings, so that the attitude of the threshing device changes. The unlocking point of the locking claw with respect to the threshing device changed in accordance with the horizontal swing of the vertical transport device, and the posture of the grain culm put into the threshing device was not constant. An object of the present invention is to provide an upright guide that can be adapted to a form in which a vertical conveyance device swings left and right. According to a characteristic configuration of the present invention, a first guide corresponding to a transport path for transporting the standing guide by vertically locking the transport grain culm, and a threshing device inlet. A point that is configured by a second guide that is located nearby and that changes the locking claw that is in the upright posture to the receding retracted posture, and that the first guide and the tip locking transport device integrally swing with the tip locking transport to move the tip locking transport. It is attached to the device supporting frame, and the second guide is installed in a state in which its posture does not change with respect to the rear fulcrum axis. Its action and effect are as follows. A. A first guide that retains the function of merely maintaining the standing guide in the posture in which the locking claws are locked in the vertical position, and the threshing device by releasing the locking action of the locking claws. The second guide is divided into a second guide having a function of setting the timing of switching the engaging claw from the upright posture to the fallen and retracted posture so as to be delivered to the rear fulcrum shaft (the swing fulcrum shaft of the rear conveyance device). ) Can be set so that the posture does not change. Therefore, even if the vertical conveying device swings to the left and right, the second guide is fixed and therefore always in a fixed posture with respect to the entrance of the threshing device, so that the conveying grain culm can always be maintained in the best throwing posture. As a result, since the grain culm posture to be thrown into the threshing device can be maintained at a predetermined posture, the threshing action can be carried out smoothly. EXAMPLE As shown in FIG. 8, the combine is a weeding tool 1

A guide 73 is provided. The upright guide 73 is a linear first guide 73A attached to the tip locking transporting device case 56 corresponding to a transporting route for transporting and transporting the transported grain culms in a vertical direction,
The semicircular second member arranged around the rear fulcrum shaft 43 in order to switch the locking claw 72 in the upright acting posture to the fallen and retracted posture.
It consists of a guide 73B. Further, in the vertical conveying device 6, the head end conveying device 6A is installed in a direction away from the threshing feed chain 38 with respect to the stock-source holding and conveying device 6B approaching the threshing feed chain 39. , 6B, the transfer grain culm is gradually laid down in a horizontal posture, and the transport grain culm in the horizontal position is transported by the transport device 6
It is the second guide 73B that sets the unlocking timing of the locking claw 72 corresponding to the time of inserting it into the inside, and this second guide 73B makes the upper end of the vertical transmission case 52 into a semicircular shape. The upper end of the semicircular shape is inserted into the case 56 through the hole 56a on the side of the tip locking and conveying device case 56, and the upper end is not changed with respect to the rear fulcrum shaft 43. As shown in FIG. 5, it is possible to avoid a point that cutting weeds or the like are accumulated on the screw shaft 28 that laterally slides the cutting pretreatment mechanism 17 and the first sliding frame 23 to cause malfunction. Therefore, a cover 70 that covers the entire pre-mowing treatment mechanism 17 is provided. [Other Embodiments] As the second guide 73B, a dedicated one may be separately provided.

Field of the Invention The present invention supports a cutting pretreatment mechanism for cutting grain culms so as to be laterally movable with respect to a traveling machine body equipped with a threshing device. A feed / conveying device for feeding the grain culms cut by the pre-reaping mechanism to a rear threshing device, and the supply / conveying device is provided with the starting end side being up and down and left and right with the rear conveying end side as a swing fulcrum. The present invention relates to a combine harvesting pretreatment device configured to be movable in any direction. In this type of combine harvesting pretreatment device, when the harvesting pretreatment mechanism is laterally moved laterally, the rear end side of the main support body that supports the harvesting pretreatment mechanism is used as a fulcrum. By swinging the front end side to the left and right, the entire pre-mowing treatment mechanism is configured to move laterally from side to side.
There is also a supply / conveyance device configured to swing left and right around a rear fulcrum (see, for example, Japanese Patent Publication No. 53-27171). However, the above-mentioned conventional structure has the following problems. In other words, the main support swings up and down to adjust the cutting height, and it is not realistic to swing the main support itself left and right, and the structure becomes complicated. In addition, regardless of the left-right swing of the main support, after moving the pre-mowing treatment mechanism to the left and right, it moves left and right while maintaining the desired forward-looking posture without changing the orientation of the pre-mowing treatment mechanism. How to do so, how to prevent conveyance failure due to positional change between the cutting pretreatment mechanism and the feeding and conveying device that occurs with the lateral movement of the cutting pretreatment mechanism, etc. No solution was provided for the insistence on demand. The present invention was devised with these points in mind, and laterally moves the mowing pretreatment mechanism laterally, and laterally moves the supply transporting device together with the mowing pretreatment mechanism, so that the cut grain culms can be smoothly moved. The present invention provides one rational and effective solution to carry the material backward and supply it to the threshing device. As a result, for example, when the uncut grain culm is located on the left side and is rotated in the counterclockwise direction, the left side portion of the pre-reaping processing mechanism is projected to the left outer side of the traveling machine body to cut the uncut grain culm. By increasing the distance between the left crawler traveling device and the left crawler traveling device, mud pushed out by the left crawler traveling device pushes down uncut grain culm, or mud adheres to the uncut grain culm It is possible to prevent cutting and damaging the cutting blade in the next step, and when slicing uncut grass on both the left and right sides for splitting work, the cutting pretreatment mechanism is installed on the left and right center side of the traveling machine body. By positioning the weeding tool in front of the crawler traveling device on both the left and right sides, it is possible to prevent pushing down uncut grass culms and perform effective swivel cutting work and middle split work. It realizes the cutting pretreatment apparatus Unishi were combined. [0004] In the technical means of the present invention taken to achieve the above object, a cutting pretreatment mechanism for cutting grain culms is mounted on a traveling machine body equipped with a threshing device. While supporting laterally movable to the main support body, a supply and conveyance device for feeding the grain culms cut by the reaping pretreatment mechanism to the rear side threshing device is provided, and the supply and conveyance device is provided at the rear side. The starting end side is configured to be vertically and horizontally movable with the end point of conveyance as a swing fulcrum, and the cutting pretreatment mechanism and the feeding and conveying device are arranged so that the feeding and conveying device is allowed to move left and right and left and right by changing the front and rear positions thereof. An end-side transfer path of the scraping transfer device and a start-side transfer path of the supply transfer device, which are interlockingly connected to each other via a connection mechanism that enables vertical movement and are provided on the stocker side of the pre-mowing treatment mechanism. And in the transport direction In order to maintain the overlapping state in the front and rear regardless of the lateral movement of the pre-mowing treatment mechanism, the feeding direction end side of the feeding grain culm guide body forming the sweeping transport path of the sweeping transport device and the supply That is, the mutual relational position with the position of the conveyance start end side of the conveyance device is set. The effect of taking the above technical means is as follows. a. After the lateral movement, the mowing posture of the mowing pretreatment mechanism with respect to the traveling body can be laterally moved to the traveling body side while maintaining the desired forward posture in the lateral direction of the body. Therefore, even if the cutting form is changed, such as switching from swiveling to middle cutting, there is no inconvenience that the direction of the cutting blade changes. b. The cutting pretreatment mechanism and the feeding and conveying device are connected to the main support by connecting the feeding and conveying device through a connecting mechanism that allows the start and end positions of the feeding and conveying device to change in the front-rear direction and can move in the left-right and up-down directions. Since the lateral movement of the pre-mowing treatment mechanism in the left-right direction and the lateral movement of the feed conveying device on the starting end side around the rear fulcrum axis are accurately linked, the movement of the feeding conveyer device relative to the pre-mowing treatment mechanism is adjusted. , It becomes possible to automatically interlock according to the movement amount of the pre-mowing treatment mechanism. The feed and transfer device is moved in the left-right direction in conjunction with the horizontal movement of the pre-mowing treatment mechanism in the left-right direction, and the vertical movement can also be accurately performed.
The handling depth control by the supply and transport device, which is essential for threshing work, can be appropriately handled. c. In order to maintain a state in which the trailing-side transport path of the scraping transport device and the leading-end transport path of the supply transport device overlap in the front and rear in the transport direction, regardless of the lateral movement of the reaping pretreatment mechanism, the scraping is performed. Since the mutual relation position between the conveying direction end side of the conveying grain culm guide body constituting the scraping conveying path of the conveying device and the conveying start end side position of the supply conveying device is set, the conveying grain of the scraping conveying device is set. While the baton touch section between the culm guide body and the transport start end of the feed transport device is always maintained in the wrapped relational position, the start end side of the feed transport device is moved backward in conjunction with the lateral movement of the pre-mowing treatment mechanism in the left-right direction. It can be moved laterally about the fulcrum axis.
Therefore, the starting end side of the supply transport device is kept at a suitable relation position with respect to the transport path of the scraping transport device of the pre-mowing treatment mechanism, and the left and right lateral movement range of the pre-mowing treatment mechanism is enlarged to move laterally. Thus, the grain culm can be delivered and received from the pre-mowing treatment mechanism to the feeding and conveying device in good condition, and the grain culm can be smoothly conveyed from the pre-mowing treatment mechanism to the feeding and conveying device. Further, also in the mowing and threshing work in which the main support is moved up and down and the cutting height is changed, it is possible to maintain the above-mentioned relational position and perform the delivery and transfer of the good grain stems. The effects of taking the above technical means are as follows. In other words, with a simple structure, the cutting pretreatment mechanism can be moved laterally and the feeding and conveying device can be interlocked with it, and the posture of the cutting pretreatment mechanism after lateral movement can be maintained in the desired forward posture. In addition, when the cutting pretreatment mechanism is laterally moved to the left or right, the state in which the trailing-side transport route of the scraping transport device and the leading-end transport route of the supply transport device overlap in the front and rear of the transport direction In order to maintain it, the baton touch part between the transporting grain culm guide body of the scraping transporting device and the transporting start end part of the supply transporting device is always kept in the wrapped relational position. By increasing the effectiveness of the stalks, the cutting pretreatment mechanism can successfully transfer the stems to the feeding and conveying device. As a result, it is possible to smoothly switch from the swiveling work to the middle cutting work, or from the middle cutting work to the swiveling work or the edge cutting work, and it is possible to effectively perform each work mode.
