この考案は、コンバイン本機の後端に装備され
る排ワラドロツパーに関する。[Detailed Description of the Invention] This invention relates to a waste straw dropper installed at the rear end of a combine harvester.

いる。 In general, the straw removal dropper receives and collects the waste straw transported in a horizontally suspended position in the straw removal conveyance chain in fixed quantities using the straw receiving device, and then moves the waste straw receiving device around the horizontal support shaft on the front edge of the straw receiving device. It is configured to swing downward from the center to drop and release the collected and waste straw.

先側への必要な寄せしろは長稈ほど大きくなる。 In a combine harvester, it is necessary to release the waste straw collected by the waste straw dropper onto the already cut field which is outside the machine passage width for the next process.Generally, the side of the waste straw plant base is the uncut side, so the waste straw is collected by the waste straw dropper. It is required to release it close to the tip side. The longer the culm is, the larger the required margin to the tip side becomes.

のであつた。 As one of the means for discharging such discarded straw toward the tip side, the discarded straw receiver is made to be freely adjustable in rotation around the vertical axis, and the discarded straw receiver is adjusted to the base of the stock in a plan view. It is known that the straw is set in an inclined position with the side facing backward, and the stock of waste straw supplied in a horizontal position is turned to move it toward the rear tip side. However, in the case of a device that can change the posture by rotating the straw receiving device, the pivot axis of the receiving device is provided at the rear end of the combine harvester, for example, as in the case of Utility Model No. 53-58186. In order to increase the turning angle and provide sufficient clearance for the base of the stock, the turning axis must be located far away from the rear end of the machine. The amount of protrusion of the dropper became large, and if the aircraft was tilted backwards when going over a ridge or loading into a vehicle using the footboards, the dropper was likely to contact the ground and be damaged.

格納できるようにしたものである。 When making the straw-receiving device adjustable in its rotation, this invention uses a rational setting of its pivot axis to switch the straw-receiving device to an inclined position so that the straw can be moved largely toward the tip of the head when the stock is turned. Despite the fact that it can be stored in a refrigerator, the amount of protrusion toward the rear of the machine is minimized so that it can be stored.
