The threshing grain is stored on the side of the threshing machine. It is supplied into the tank and temporarily stored.
[0003]
After the harvesting operation is finished with the combine, the compressed air from the compressor is sprayed from the cleaning nozzles provided at a plurality of positions on the body of the reaper and the threshing machine, and the inside of each of the reaper and the threshing machine , And residues (debris, dust, etc.) that adhere to and accumulate on the periphery of the functional parts are removed and cleaned.
[0004]
In addition, when trouble occurs during harvesting work, when repairing or replacing parts in the field, the compressed air of the compressor is taken out as a power source, and for example, an impact wrench, grinder, etc. are operated. Therefore, it is not possible to operate various repair tools in the field to perform repairs, replace parts, and the like. Moreover, the operation of a car wash machine that performs car washing or the like cannot be performed, and car washing cannot be performed in the field. Moreover, only the air nozzle is provided in each part of the combine, and this compressor is arranged under the Glen tank (for example, refer to Patent Document 1).

[0025]
As a result, the heavy engine 16 and the compressor 5 are arranged on the left and right traveling crawlers 6a, 6a and at substantially the same position in the front-rear direction, so that the left-right and front-rear balance is reduced. Can be difficult.

[0027]
The compressor 5 and the threshing machine 4 are driven to rotate through the counter box 25. Further, the counter box 25 is arranged between the engine 16 and the threshing machine 4.
As a result, both the compressor 5 and the threshing machine 4 are driven and transmitted via the counter box 25, so that the belt tension devices 24c and 26d can be separately "ON" and "OFF". Moreover, since the counter box 25 is disposed between the engine 16 and the threshing machine 4, the space between the shafts can be secured in a narrow space.

[0030]
As a result, the rotational power of the engine 16 is directly input to the compressor 5, and the compressor 5 is driven and the compressed air can be taken out only by starting the engine 16. Further, when the engine 16 is started, the compressor 5 is turned off, so that the load on the battery is reduced and the startability is improved.
[0031]
As shown in FIG. 1, the rotational power from the engine 16 is configured to rotationally drive the compressor 5 by a transmission mechanism 24.

If the detected pressure is equal to or higher than a predetermined value, the belt tension device 24c is “turned off” by this detection, and the rotational drive of the compressor 5 is controlled to stop.
[0032]
As a result, the pressure of the compressed air in the air tank 29a is detected by the pressure sensor 30, and the rotational driving of the compressor 5 is stopped and controlled by the detected pressure, thereby reducing the power consumption of the engine 6. it can.

If detected, the belt tension device 24c is "turned off" by this detection, and the rotational drive of the compressor 5 is controlled to stop.
[0033]
Thereby, the rotation speed of the engine 16 is detected by the rotation sensor 31, and the rotation driving of the compressor 5 is controlled to stop by this detection, so that the work consumption power during the harvesting operation by the combine 1 becomes a high load. When this occurs, the rotational speed of the engine 16 decreases. At this time, the threshing performance decreases. At this time, the performance of the threshing machine 3 can be prevented from being lowered by stopping the compressor 5.
[0034]
A turning sensor 32 for detecting the turning of the combine 1 is provided as shown in FIG. 4, and the turning detected by the turning sensor 32 is input to the CPU 15c, and by this input, the belt tension device 24c is "turned off". In this configuration, the rotational power of the compressor 5 is controlled to stop.
[0035]
Thereby, when the combine 1 is turned, the running resistance increases, the power consumption of the engine 16 increases, and the rotational speed of the engine 16 decreases. However, the rotational drive of the compressor 5 is temporarily stopped. Moreover, the fall of the rotation speed of the engine 16 can be prevented, and the stable threshing performance can be ensured.
[0036]
On the rear side of the grain storage tank 8 for discharging the grains stored in the grain storage tank 8 to the outside of the machine, a discharge support cylinder 19 equipped with a vertical transfer spiral 19a is rotatably mounted in a substantially vertical posture. The upper end of the discharge support cylinder 19 is provided with a discharge auger 33 that is extendable and retractable.
