本考案は、扱深さを自動的に調節できるように
したコンバインの扱深さ調節装置に関する。[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a working depth adjusting device for a combine harvester that can automatically adjust the working depth.
従来、この種の装置においては、扱深さ調節体

Conventionally, this type of device has been constructed so that the operating speed of the handling depth adjuster is equal over the entire length of its operating range.

扱深さ状態から平均的な扱深さ状態に復帰する速
度も遅くなり、扱き残しや脱穀装置での過負荷状
態を必要以上に継続させる不都合を生じる。 As a result, the displacement of the vertical conveyance device becomes large, and there are drawbacks such as hunting occurring in automatic control and the inability to adjust the handling depth. Therefore, it is conceivable to slow down the operating depth over the entire length of the operating range, but if the operating depth suddenly changes from an average operating depth to an extremely shallow or deep operating depth, the change will be delayed. This has the disadvantage of causing a delay in the displacement of the vertical conveying device, resulting in low responsiveness, and the speed at which the handling depth returns from a shallow or deep handling depth state to an average handling depth state is slow, resulting in unhandled items and This results in the inconvenience of continuing the overload state in the threshing device for longer than necessary.
本考案は、実情に即し、扱き残しや過負荷状態

In order to achieve the above object, the handling depth adjustment device for a combine harvester of the present invention is such that a vertical conveying device for supplying grain culm to the feed chain of the threshing section is movably attached to the machine body, and the vertical conveying device is automatically operated. A handling depth adjustment member is provided, which is linked to the sensor via a control device so as to maintain the handling depth detected by the sensor within a set range, and at approximately the center of the operating range of the handling depth adjustment member.

Depending on the degree of handling depth detected by the sensor, the control device is actuated to operate the handling depth adjustment body. At this time, for grain culms that are at an average handling depth, the handling depth is automatically finely adjusted by the central portion with a slow operating speed without causing hunting. On the other hand, for extremely shallow or deep grain culms that appear suddenly, other parts except the center can respond quickly and return quickly.

As can be understood from the above embodiments, the present invention makes the movement of the handling depth adjuster slower in the approximate center of the operating range than in other parts. For grain culms that are in a deep handling state, the central slow operating speed part allows fine adjustment of the handling depth automatically without causing hunting, and on the other hand, for extremely shallow or deep grains that suddenly appear. Other parts can quickly respond to grain culms that are in a state of disrepair, and recovery can be done quickly, avoiding unforeseen situations such as unhandling and unnecessary continuation of an overloaded state in the threshing equipment. , automatic adjustment of handling depth became possible.
