A crank 43 having a roller 42 that fits into the blade 9 is fitted, and the movable blade 28 is rotated by the rotation of the crank 43.
is configured to move back and forth.

Note that the bevel gear 41 on the vertical shaft 33 is
3, a boss portion 44 integral with the bevel gear 41 projects outside the gear case 34, and the boss portion 44 and the vertical shaft 33 are connected to each other by a safety pin 45. Also, the vertical axis 3
Power is transmitted to the binding device 16 through a chain 49 wound between the sprocket 46 fitted on the upper end of the binding device 3 and the sprocket 48 on the input shaft 47 of the binding device 16, and then to the output shaft 50 of the binding device 16. The grain culm pulling mechanism 14 is driven by transmitting power to the vertical shaft 52 through a chain case 53 installed between the gear case 51 attached to the upper end of the grain culm pulling mechanism 14 and the lower end of the vertical shaft 52. A vertical shaft 52 to the grain culm pulling mechanism 14 is provided with a pair of upper and lower conveyor wheels 54 and 55 for feeding the grain culms in the direction of the bundling device 16.

In this configuration, when the reaping and tying machine 1 moves forward, the grain culm that is being pulled up by the grain culm lifting mechanism 14 and reaped by the reaping mechanism 15 is transported by a conveyance guide provided at a position substantially above the reaping mechanism 15 with the tip of the grain. Board 5
6 and supported by the grain culm conveyance path 57 by the rotation of both conveyance wheels 54 and 55, where it is bundled into an appropriate amount. , string coil 8
The base of the stock is bound with the string fed out from the cord, and then released to the right side of the reaping and binding machine 1.

[Effect of idea]

As described above, the gist of the present invention is the configuration described in the claims for utility model registration, and the crank for reciprocating the movable blade in the reaping mechanism protrudes downward integrally from both the left and right sides of the gear case. Since it is located between the two legs and is surrounded on both sides by the two legs, the worker's hands and feet do not touch it, resulting in high safety. By attaching the reaping binding frame to both legs that integrally project downward from both left and right sides of the gear case,
The mounting strength is improved, and a cover for the crank for reciprocating the movable blade in the reaping mechanism is not required, thereby simplifying the structure.
