DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an improvement of a combine harvester equipped with a reaping section that can be raised and lowered.

(Prior art) A combine harvester that automatically adjusts the height of the reaping section has a height sensor that detects the height of the reaping section, and the sensor output drives and controls the lifting mechanism of the reaping section to set the reaping section. Although the reaping section is automatically raised or lowered to a certain height (for example, Japanese Utility Model Application Publication No. 57-109738), the reaping section can also be raised or lowered to an arbitrary height by manual operation as necessary.

(Problem to be Solved by the Invention) When lowering the reaping section manually in such a combine harvester, conventional automatic height adjustment does not work during manual operation, so the inertia of the reaping section and the lifting device Due to delays in the response of hydraulic valves, accidents tend to occur where the mowing section crashes into the ground, damaging the cutting rods and cutting blades.

The present invention prevents such accidents from occurring, and when lowering the cutting section manually, it prevents the cutting section from being lowered too low inadvertently, thereby making the cutting rod and cutting blade safe from collision with the ground. The purpose is to protect.

(Means for Solving the Problems) In order to achieve this object, the present invention includes a ground sensor that outputs a ground signal when it comes into contact with the ground surface, which is attached to a branch rod equipped with a known culm tracking sensor. A reaping section elevating mechanism is provided which raises the reaping section when the reaping section approaches the ground surface based on this grounding signal.

(Function) 1. Since the present invention has the above configuration, the culm tracking sensor moves the weeding rod between the culm rows in the field, so the ground sensor does not touch the culm and moves the culm. It moves between the culm rows and the shell culm rows, correctly detects contact with the ground surface, and raises the reaping section when it approaches the ground surface.

(実施例) 次に本発明の実施例を図面に基いて説明する。(Example) Next, embodiments of the present invention will be described based on the drawings.

Reference numeral 9 indicates a known culm tracking sensor installed on the back side of the weed cover of the weeding rod 4. Once the culm strongly contacts either the left or right side of the vane plate 9b pivoted on the shaft 9a, the vane plate 9b is rotated at a certain angle or more. When turning, a signal is sent to a steering device (not shown) of the combine to change the direction of movement of the aircraft, thereby controlling the direction of the aircraft so that it follows the culm row into the chamber.
