Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement in the transportation state of a harvested grain rod in a combine, and more specifically, a traveling speed and a drive speed of a harvesting section are coordinatedly linked, and a feed chain driven at a constant speed is provided. The end part of the vertical transfer device that transfers the grain rods of this type to the feed chain is configured to be vertically or horizontally positionable so that the handling depth can be adjusted, and it is transferred by the vertical transfer device. Provided on the harvesting section is a horizontal-type auxiliary transfer device that acts on the middle part of the rod in the direction of the rod to give a rearward transfer force, and is positioned at the end of the vertical transfer device. The present invention relates to a combine grain rod transport structure in which the drive speed of the auxiliary transport device is synchronized with the drive speed of the cutting unit.

[0002]

[Prior Art]

 In this type of combine, as shown in Japanese Utility Model Laid-Open No. 58-100534, a vertical conveying device is constituted by a tip locking conveying device and a stock holding device, and the stock holding device is attached to the front end of the device. It was possible to adjust the handle depth by swinging it up and down around the axis provided on the section to change the stock position. Then, when the stock holding device is lowered and oscillated to accommodate the long rod and its end is lowered, the distance to the tip locking transfer device tends to be separated and the delivery to the feed chain is disturbed. In order to prevent the instability, it was equipped with an auxiliary transfer device that acts on the middle part of the grain rod in the rod direction to assist the transfer force to the feed chain.

[0003]

[Problems to be solved by the device]

 However, although the transfer condition of the grain rod from the vertical transfer device to the feed chain was improved by installing the auxiliary transfer device, the improvement was not as high as expected, and the transfer disturbance still occurred. As it can be seen, there is room for further improvement. An object of the present invention is to improve the delivery condition of the grain rod from the vertical transport device to the feed chain.

[0004]

[Means for Solving the Problems]

 For the above-mentioned purpose, the present invention is directed to the combine grain rod conveying structure described at the beginning, in which the rotation along the rotation axis of the feed chain is carried out between the terminal end portion of the auxiliary conveying device and the feed chain starting end portion. The relay transfer device consisting of an endless rotating body with an axis is installed on the machine in a state where the power input to this relay transfer device is taken out from the drive system of the mowing unit, and at the end of the relay transfer device the transfer of grain rods is performed. The arrangement is characterized in that the height position of the relay conveyance device is set such that the height position of the surface matches the height position of the grain rod transfer surface at the starting end of the feed chain.

[0005]

[Action]

 According to the above characteristic configuration, since the vertically-rotating type relay conveying device is provided after the horizontally-rotating type auxiliary conveying device, the auxiliary conveying force that matches the posture change of the grain rod changing from the vertical posture to the horizontal posture can be obtained. In addition, since the height position of the grain rod transfer surface at the terminal end of the relay transfer device is set to match the height of the grain rod transfer surface at the start end of the feed chain, the auxiliary transfer device alone is used. The relay carrier now carries the grain rods that cannot be delivered smoothly to the starting end of the feed chain. Regardless of what you do, you will always be able to deliver the rod to the feed chain without disturbing it. In other words, it was found that the conventional conveyance force was the lateral rotation type, so that the conveyance force would not reach near the start end of the feed chain, which is almost in the horizontal position, and a vertical rotation type relay conveyance device is newly provided. The idea was taken.

[0006]

[Effect of the device]

 As a result, a new vertically-rotating type relay transfer device, which was obtained by carefully observing and examining the transport state of the grain rods, provided a smooth and good transport state of the grain rods from the vertical transport device to the feed chain. Thus, it was possible to provide a grain rod transport structure that can contribute to the improvement of threshing performance.

 An embodiment of the present invention will be described below with reference to the drawings. A side view of the front part of the combine is shown in Fig. 1, and 3 is a vertical transfer device composed of a tip-end locking transfer device 3A and a stock holding device 3B. The stock holding device 3B is provided at the front end thereof. It is configured to be swingable left and right around the axis P, and the swinging movement allows the end portion of the vertical transport device 3 to be repositioned in the left and right direction, and the threshing portion 2 can be adjusted in handling depth. Is done. At the position just below the end of the tip-end locking transfer device 3A, a horizontal-type auxiliary that applies a transfer force to the rear side of the rod transferred by the vertical transfer device 3 by acting on the middle part of the rod direction. The transport device 4 is fixedly provided on the cutting unit 1. That is, as shown in FIG. 2, the drive roller 4a of the auxiliary carrier 4 having the locking carrier structure is attached to the rotary shaft 5 of the roller 3a of the tip locking carrier 3A.
