Description

[Detailed Description of the Invention] [Industrial field of application] The present invention provides a large distance between the left traveling device and the uncut grain culm during mowing so that the mud extruded by the traveling device is buried at the base of the uncut grain culm. The cutting part is moved to the left side of the rear threshing device so as to prevent it from being piled up and carried to the threshing device in the next cutting, and when cutting the entire surface, do not step on the uncut grain culm with the right traveling device this time. In order to set the mowing unit to approximately the center, the mowing unit including the raising device and the mowing device is configured to be laterally movable with respect to the rear threshing device,
The vertical transport device that transports the harvested culm to the rear threshing device in a vertical posture by the tip-end transporting device and the stock holding device can swing left and right around the rear fulcrum following the lateral movement of the harvesting part. Relates to a combine harvesting pretreatment device.

[Conventional technology]

In the one in which the cutting unit is moved laterally as described above, in order to favorably transfer the grain culverts from the raising device to the vertical transfer device, the vertical transfer device is moved around the rear fulcrum along with the horizontal movement of the cutting unit. Although it was configured to be able to swing to the left and right, it has the same configuration as a tip locking transport device of a type that does not swing to the left and right with respect to the tip locking transport device.

[Problems to be solved by the invention] However, in consideration of the fact that the vertical conveying device transfers the threshing feed chain favorably, it is configured to be swingable left and right around the rear fulcrum, so that The distance from the moving raising device changes depending on the position of the cutting unit. Actually, when the reaper is located at the right end, the distance between the raising device and the starting end of the vertical conveying device becomes maximum, and as shown in FIG. ) In some cases, the transporting pawl (18) could not be locked, and delivery was not successful.

An object of the present invention is to provide a grain culm which can be smoothly transferred from the raising device to the vertical conveying device by additionally forming a rational mechanism at the start end of the tip locking conveying device.

[Means for Solving the Problems]

According to the characteristic configuration of the present invention, a sweeping turn is provided at the transporting start end portion of the tip locking transporting device, which has a grain stalk scratching locking claw having a larger range of scraping action than the locking transporting claw of the tip locking transporting device. The moving body is provided and the scraping locking claw is formed so as to be elastically deformable. The action and effect are as follows.

[Action]

That is, as shown in FIG. 1, when the distance between the raising device (6) and the leading end of the tip locking and conveying device (13) is wide, a long raking and locking pawl of the raking rotary member. (20A) pulls up and locks the grain culm to the working area of the tip locking transporting device (18), and when the gap is narrowed, the scraping locking claw (20A) raises and the case or Even if it interferes with the pull-up claws and the like, it is possible to avoid mutual damage by escaping due to elastic deformation.

[Effect of device]

Therefore, not only is a scraping locking claw having a large scraping action range provided, but a scraping locking claw that is elastically deformable in accordance with the state in which the distance between the raising device and the tip locking transport device changes. With this configuration, there is no need to make modifications such that the start end portion of the tip locking and conveying device can be expanded and contracted, and the locking and conveying claw is lengthened unnecessarily.

[Operation and effect of claim 2] In this case, the scraping action of the scraping locking claw is regulated so that the range of action of the scraping locking claw is limited and the scraping action is performed only within a necessary range. With the restricting device, it is possible to prevent the scratching locking claws from being unnecessarily damaged by contact with other articles (for example, a steering box located on the lateral side of the vertical conveyance device).

In addition, it is possible to prevent unnecessary scraping of straw scraps or the like that happen to exist between the control box and the control device.
It does not reduce threshing efficiency.
