As shown in FIGS. 6 to 8, the mowing machine 3 is provided with a depth-adjusting transfer device 34 for adjusting the handling depth of the grain culm according to the culm length of the grain culm. Due to the rotation of the deep motor 35a, the adjusting lot 35b provided in the handling motor 35a controls the adjusting and moving of the handling control device 34 by the CPU 37b of the control device 37a according to the detected culm length of the grain culm. Configuration.
[0051]
At the supply port where the grain culm is supplied to the threshing machine 12, an actuator for detecting the handling depth of the grain culm supplied as shown in FIGS. 6 to 8 and a switch which is turned ON / OFF by this actuator A long culm handling depth sensor 36a and a short culm handling depth sensor 36b are provided. When the switches of both the long and short culm sensors 33a and 33b are ON, it is determined that the long culm is threshing. Configuration. When the switch of the long culm depth sensor 36a is OFF and the switch of the short culm depth sensor 36b is ON, the standard culm is determined to be threshing. Furthermore, when both the long and short culm handling depth sensors 36a and 36b are in the OFF state, the short culm is determined to be threshing. The input and determination of each switch of the long and short culm handling depth sensors 36a and 36b are input to the CPU 37b of the control device 37a and are determined.
[0052]
Even if the handling depth adjusting transfer device 34 is adjusted to the maximum position of the long culm or the short culm, when the threshing machine 12 is not adjusted to the optimal handling depth position, the harvesting is performed. The machine 3 is controlled so that the upper and lower parallel link mechanisms 6 and 7 of the transfer device 5 are translated leftward or rightward with respect to the fuselage 1a of the combine 1 by the movement motor 27, so that the long culm of the grain culm can be obtained. Or it is a structure corrected so that it may become appropriate handling depth with respect to short culm, and it can be set as the 2nd supply depth adjustment device.
[0053]
Thereby, the adjustment range of the handling depth of the grain culm is 500 to 1200 mm at present, but if it exceeds this range, the entire reaper 3 is corrected and adjusted, with respect to the culm length of the grain culm, By threshing at an appropriate handling depth, the sorting performance and the third fly ash performance can be stabilized. Further, the threshing efficiency can be improved.
[0054]
As shown in FIGS. 2 and 5, an operating device 37 for performing operations such as starting, stopping, and adjusting the components of the combine 1 and a worker for performing these operations are mounted on the front portion on the threshing machine 12 side. The cockpit 38 is provided in an operation room 39b formed by an operation room case 39a. The engine 22 is mounted on the upper side surface of the traveling chassis 2 below the cockpit 38 and a rear portion thereof. , A grain storage tank 14 is provided. The traveling device 11, the reaper 3, the threshing machine 12, the engine 22, and the like form a body 1 a of the combine 1.
[0055]
In the transmission path of a transmission mechanism 21a in a traveling transmission case 21 mounted on the front end of the traveling chassis 2, a potentiometer type vehicle speed sensor 21b for detecting the traveling vehicle speed based on the output thereof is provided. Configuration.
On the rear side of the grain storage tank 14 for discharging the grains stored in the grain storage tank 14 to the outside of the machine, a discharge support cylinder 40 provided with a vertical transfer spiral 40a is pivotably mounted in a substantially vertical posture. A discharge auger 41 is provided at the upper end of the discharge support cylinder 40. The discharge auger 41 is provided with a discharge spiral 41a for discharging grains outside the machine, the total length of which extends over the length of the combine 1. It is configured to be rotatable and left / right swivelable in the front-rear direction.
