Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a threshing culm binding device for binding culms threshed by a threshing device, and can be used for binding culms of a combine harvester.

BACKGROUND ART A binding device is moved and adjusted in the direction of the culm of the culm of a threshing device to adjust the binding position, or the culm is transferred and supplied to the tying device in the process of moving and adjusting the culm. A configuration in which stocks are aligned by striking the end face of the stocks is already known.

Problems to be Solved by the Invention When tying threshed culms using a tying device, a culm alignment board is provided to align the culm by hitting the end face of the culm at the tying position. It is necessary to adjust the movement of the plate toward the culm depending on the culm length of the culm, and it is time-consuming to manually adjust the plate each time the culm changes during work.

Means for Solving the Problems This invention provides a binding device (2) for transporting threshed culms (1).
Along the stock transfer end surface of the culm supply device (3) for supplying the culms to the stock supply device ( 3) on the starting end side of the bundling device (2), which moves integrally with the terminal end of the stock alignment plate (4) in the direction of the culm to tie the bundling culm (1) from the stock base. The structure of the threshing and culm binding device is provided with a stock alignment sensor (6) that controls the movement of the plant according to the culm length.

Effect of the Invention The threshed culms (1) threshed by the threshing device (7) are supplied to the binding device (2) by the feeding device (3) and bound, but the transferred and supplied culms ( 1), the culms (1) at the bundling position are aligned at the same level by being struck from the end face of the stock by the stock alignment board (4), and the end faces of the stock are loosened and aligned at the same level. If the culm length is too long, the length from the bundling position to the end face of the stock will increase, and the stock alignment plate (4) will hit the stock alignment board (4) from beginning to end, causing it to bend. When the stock alignment sensor (6) is activated, the position of the end of the stock alignment plate (4) relative to the binding device (2) is moved toward the stock base side.
At the bundling position, an appropriate position is selected and controlled where stock alignment can be easily performed by striking the end face of the stock base with the stock alignment plate (4). Also, culm (
If the culm 1) is too short, the culm may not be struck by the stock alignment plate (4), but in the case of such a short culm, the stock alignment sensor (6) will By adjusting and controlling the movement of the terminal end to a position where it approaches the binding device (2), the end face of the stock is placed within the striking range of the stock alignment plate (4).

Effects of the invention The culm (1) thus supplied to the binding device (2) is
Before the stock alignment is completed by being struck by the stock alignment plate (4), the end position of the stock alignment plate (4) is detected by the culm length of the culm (1), and the culm length of the culm (1) is detected. Since it is automatically controlled to adapt to the culm length, accurate stock alignment can be performed.
