(b) Conventional technology Conventionally, in the reaping section of a combine harvester, a grass division board is fixed to the tip of the reaping frame, a pulling device is installed behind it, and a cutting blade is arranged at the rear lower part of the device. An ear tip conveying device is installed above and a stock root conveying device is installed in the lower part, and the grain culms separated by the weed cutting board are pulled up by the pulling device, the roots are cut by the cutting blade, and each conveyance is carried out. The device was configured to transport the grain to the rear threshing and sorting section, and at this time, the cutting blade was installed at an approximately horizontal angle.

(c) Problems to be solved by the invention However, because of the above structure, when the traveling section is operating at low speeds, the entire reaping section tends to float up when operating at high speeds, compared to when operating at low speeds, resulting in a tendency to cut at a high rate. Not only that, but the length of the grain culm becomes uneven, and when it is transported to the threshing section by a conveying device equipped with a threshing depth adjustment mechanism behind it, the lower end of the grain culm cannot be sufficiently clamped, and the grain culm becomes uneven in length. This causes unhandled paddy due to the
It also had drawbacks such as the inability to work efficiently with a tiller.

(d) Means for solving the problem In the present invention, a cutting blade whose mounting angle can be adjusted on the reaping frame is interlocked and connected to a speed change lever for operating the transmission of the traveling section. It is an object of the present invention to provide a structure for a cutting blade angle adjusting device in a reaping device configured such that the mounting angle is adjusted in conjunction with high and low speed driving operations.

(E) Effect In this invention, the cutting blades installed on the reaping frame cut the base of the grain culm while the traveling section is traveling. If you change the speed to make it as fast as possible, the attachment angle of the connected cutting blade will be adjusted to increase, so even if the entire cutting section floats up, the cutting blade will maintain a substantially constant cutting angle with respect to the ground. On the other hand, when the running speed is low, the mounting angle of the cutting blade becomes smaller in conjunction with the transmission, and because the floating of the grain culm that is scraped into the cutting section is small, the height is maintained at a predetermined height. Regardless of whether the machine is traveling at high or low speeds, the cutting inclination angle relative to the ground remains constant and the cutting work is always performed with the cutting blade at a fixed position at the base of the grain culm. It is something that becomes.

(f) Effects According to the present invention, by adjusting the cutting blades of the reaping section linked to the transmission during high-speed and low-speed driving to their respective mounting angles, the cutting blade inclination angle can be adjusted regardless of whether high-speed or low-speed driving is being performed. By keeping the grain culms constant and making the stock base of the grain culms almost constant, the length of the grain culms becomes constant and the conveying device functions well, eliminating unnecessary operations and eliminating unhandled paddy. Since the stump is low and constant, it has the advantage that it can be plowed with a tiller without any trouble.

The embodiment of the present invention is constructed as described above, and when performing reaping and threshing work in the combine A, the gear lever 16 is connected to the transmission lever 16 for operating the transmission 15 of the traveling section 5. The reaping operation is performed by adjusting the mounting angle θ of the cutting blade 9. When the traveling section 5 is running at high speed, the mounting angle θ of the cutting blade 9 of the reaping section 1 is set to a large value, and the reaping section 1 cuts the grain culm. The tip of the cutting blade 9 is brought into contact with the stock base of the grain culm, and the tip of the cutting blade 9 is brought into contact with the cutting inclination angle θ' at a nearly right angle to the cutting inclination angle θ' due to the energization of high-speed running, thereby cutting the grain culm. The length of the grain culm is determined by reducing the mounting angle θ of the cutting blade 9 during low-speed driving and keeping the cutting inclination angle θ′ of the cutting blade 9 relative to the ground G constant. Since the length of the grain culm is constant, it can be transported to the rear threshing section without any trouble, and the paddy can be removed without unnecessary threshing depth adjustment. By eliminating unused fields and lowering the height of stumps, plowing work can be carried out more efficiently.
