Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention places a pre-mowing treatment mechanism and a control section on the front side of a traveling machine body, and further comprises the pre-mowing treatment mechanism. The present invention relates to a combine equipped with a lateral movement guide device that laterally supports the traveling body side. 2. Description of the Related Art In combine harvesters, it is suitable for round-cutting work as a standard work form in which one lateral side of the machine body (the side opposite to the control section) is cut and run as uncut land, and for turning around large fields. There is a middle-splitting work of cutting and passing through the middle of the field in advance in order to divide it into sizes. And in a small combine, the cutting width is smaller than the passing width of the left and right traveling devices in the traveling body, so in order to enable the above-mentioned splitting by traveling without stepping on the uncut land grain culms on the left and right sides of the body. It is necessary to dispose the pre-mowing treatment mechanism near the center of the front and left of the traveling body. Therefore, in a combine simply having the pre-mowing treatment mechanism arranged near the left and right center of the front surface of the traveling machine body, for example, the traveling device on the uncut land side may be close to the uncut land planting culm when turning around. In wetlands, the uncut land grain culms are tilted by the mud that is heaped up and pushed out toward the uncut area side with the sinking of the traveling device on the uncut land side, or the extruded mud is the uncut land grain. When the planted grain culm is raised next to the culm plant and the planted grain culm is subsequently mowed, the mowing device may bite the muddy soil or may carry the mowing and transporting the muddy soil with the muddy soil. Therefore, in the conventional combine harvester, in order to cope with various working modes as described above, the rear end side of the main support body for supporting the pre-mowing treatment mechanism is used as a fulcrum, and the front end side is swung left and right. By doing so, there is one that laterally shifts the entire pre-mowing treatment mechanism (for example, Japanese Patent Publication Sho 53).
-27171 gazette). However, the main support swings up and down in order to adjust the cutting height, and it is practical to swing the main support left and right. Instead, the structure becomes complicated. In addition, since the pre-mowing treatment mechanism is moved in parallel to the left and right, no means for solving such problems as to how to secure a certain posture by pivotally attaching to the main support has been disclosed. The present invention was developed by paying attention to such a situation, and at the time of turning, the cutting pretreatment mechanism is moved to the uncut area side as much as possible, and the planted culms of the uncut area are run. To avoid the above-mentioned problems caused by pushing the mud with a gap between the device and the cutting pretreatment mechanism at the front of the traveling machine during the middle cutting work, the planted culms on the left and right uncut areas can be moved by the traveling device. It is an object of the present invention to provide a rational solution that can be used in a state in which there is little risk of stepping down and that laterally moves the pre-mowing treatment mechanism laterally in the lateral direction with respect to the machine traveling direction. [0006] The technical means of the present invention taken to achieve the above-mentioned object is to provide a traveling machine body having a threshing device, a cutting pretreatment mechanism for cutting grain culms and a control section. In the harvesting pretreatment device of the combine, in which the control section is on the already mown side and the mowing pretreatment mechanism is located on the uncut side on the front side of the Of the traveling device, the amount to the control section side is set to be small and the amount to the side opposite to the control section is set to be large, and It is configured to be laterally moved in a range corresponding to a position closer to the uncut grain outer side edge of the uncut side traveling device of the uncut side traveling device,
The lateral movement guide device for supporting the reaping pretreatment mechanism so as to be laterally movable laterally with respect to the traveling body side is constituted by a pair of front and rear guide mechanisms, and the first guide mechanism on the rear side is provided on the traveling body side. The first support guide body and the first moving guide body provided on the pre-mowing treatment mechanism side are configured to be fitted together, and the second guide mechanism on the front side is the second The moving guide body is mounted on the second support guide body provided on the traveling machine body side. The effect of taking the above technical means is as follows. a. The movement of the mowing pretreatment mechanism to the control unit side is used when splitting, the amount of deviation on the control unit side is small, and the movement of the mowing pretreatment mechanism to the side opposite to the control unit is used when turning around. Since it moved to the outside from the traveling device on the opposite side of the control unit to keep the mud gathering in the wetland away from the planted grain culms in the uncut land, When the weeding tool on the side of the most uncut land is located approximately in the center between the cutting line located on the side of the most uncut land and the planting line adjacent to this on the side of the uncut land, As shown in FIG. 1, the raising device 2 can be positioned substantially above the cutting strip a on the side of the most uncut land, and the lateral movement of the pre-mowing treatment mechanism 17 also causes the raising device 2 and the most uncut portion. The positional relationship with the cutting strip a on the ground side can be maintained in a state where the raising and weeding performance is not hindered. Also, depending on the soft and hard condition of the field, the crawler traveling device 3 on the uncut area side
9 may sink to the surface of the field and push the mud to the side. In that case, by setting the relative position as shown in FIG. 1 and performing the cutting work, the mud may be pushed to the uncut side. The muddy soil to be cut off is stopped by the stump of the cutting strip a on the most uncut land side, and the movement of the mud to the uncut land side is suppressed. Therefore, it is possible to prevent the mud from adhering to the uncut grain culms and to prevent the threshing operation from being hindered by handling the cut grain culms together with the mud. b. The cutting pretreatment mechanism can be moved laterally linearly in the machine lateral direction with respect to the main support of the traveling machine.Therefore, the cutting blade can be changed by changing the cutting mode, such as switching from turning to split cutting. There is no inconvenience that the direction of the blade changes or the cutting blade moves forward to increase the overall length of the machine. c. In supporting the reaping pretreatment mechanism linearly and laterally movably in the machine width direction, it is supported and guided by the pair of guide mechanisms, and the first moving guide body is moved forward and backward by the fitting structure with the first support guide body. And the vertical movement is restricted, and the second moving guide body is placed on the second support guide body and moves laterally in the left and right direction. It moves laterally smoothly and stably without twisting the mechanism. The effects of adopting the above technical means are as follows. I. The a. From the effect of the above, a simple modification of setting the lateral movement amount of the cutting pretreatment mechanism makes it possible to perform the cutting work using the stub as a mud suppression control barrier, and more effectively avoid the influence of the extruded soil and perform threshing and sorting. While contributing to the improvement of performance, there is an advantage that it is possible to provide an excellent pre-mowing treatment device that does not cause the performance and weeding performance to be lowered even if the pre-mowing treatment mechanism is laterally moved. B. The b. From the action of, the lateral movement guide of the cutting pretreatment mechanism, the fitting of the first support guide body and the first movement guide body,
Since it can be done with a simple structure of placing the second moving guide body on the second support guide body, since it is possible to change the left and right lateral position with respect to the machine advancing direction of the cutting pretreatment mechanism by linear lateral movement, The desired pre-pruning treatment mechanism,
The raising action can be favorably performed. C. The c. As a result, the lateral movement of the pre-mowing treatment mechanism is set to a small amount to the control part side and a large amount to the opposite side of the control part, so that the pre-mowing process mechanism is smooth and well-balanced without being twisted. Lateral movement can be secured. EXAMPLE As shown in FIG. 5, the combine is a weeding tool 1
