DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a cutting blade device for cutting a puddled cereal stem by raising and lowering the cereal culm by raising and lowering the cereal culm by a raising device. The number of the upper rake nails for the rake transfer operation of the upper star wheel is made smaller by a predetermined number than the number of the lower rake nails for the rake transfer operation of the lower star wheel. This is a technique of reducing the ratio by an integer ratio, and can be used as a device for scraping and transporting a grain stalk of a binder.

[0002]

2. Description of the Related Art When a buckwheat or the like is harvested with a binder, the binder is run in a field, and the cereal stem separated by the foreground plant is raised by a raising device. The upper and lower portions of the cereal stem are raked and transferred by both an upper star foil having upper and lower rake nails having the same number of upper and lower rake nails, and a lower star wheel having lower rake nails. The cutting is performed by the device, the cut culm is collected, and the bundle is released outside the machine.

[0003]

The same number of upper and lower nails are used for the upper and lower star foils which rake and transfer the upper and lower portions of the cultivated grain stalk. At the time of harvesting harvesting, etc., the occurrence of culm breaks, and shedding, etc. in the upper upper star foil sometimes increased,
The present invention is intended to solve these problems.

[0004]

For this purpose, the present invention provides a raising device 2 for raising a culm to be cut, and upper and lower star wheels 3 and 4 for raising and lowering the upper and lower portions of the culm. In a binder provided with a cutting blade device 11 and the like for cutting the stalks, the number of the upper scraping claws 3a which act to squeeze and transfer the upper star foil 3 is reduced by the lower star wheel 4 A plurality of lower scraping claws 4b that act to perform a scraping transfer operation, the number of which is reduced by a predetermined number, and the ratio thereof is reduced by an integer ratio. is there.

[0005]

When the buckwheat or the like is harvested, the binder is run in the field, and the cereal culm separated by the foreground plant is raised by the raising device 2, and the upper and lower portions of the raised cereal culm are raised. , Rake transfer function. For example, two upper scraping claws 3a
And the lower star wheel 4 having four lower scraping nails 4a, or the upper scraping nails reduced in an integer ratio such as 3 and 6 sheets, and 4 and 8 sheets. The upper and lower star wheels 3, 4 in relation to the lower raking claw 4a are squeezed and transferred by the cutting blade device 11, and the harvested culm is bundled and bound. The finished bundle is released outside the machine.

[0006]

According to the present invention, the number of the upper scraping nails 3a acting on the upper part (ear tip) of the raised cereal stem is changed to the lower scraping nail 4a acting on the lower part (stock). By reducing the ratio to an integer ratio, the effect on the grain culm can be evenly synchronized, thereby preventing culm breakage and the occurrence of shedding. did it.
