出する。The driver operates the operating levers as described above to drive the rotating various parts of the machine such as the mowing section 7 and the threshing section 5, and at the same time move the machine forward to locate it at a predetermined place in the field, and carry out the work. When started, the ear tip side portion and the root side portion of the grain culm cut by the cutting means of the reaping unit 7 are conveyed rearward by the cut grain culm conveying means. Then, when the end of the cutting grain culm conveying means is reached, the tip portion is brought into contact with the upper surface of the flat plate 12 and the entrance funnel 1.
1 enters the handling room 13 from the supply port 6 through the upper surface of 1, and the stock root is sandwiched by the automatic grain culm feeding device 8, and the grain culm is conveyed to the discharge side of the threshing unit 5 while undergoing threshing treatment. After the threshing process, the threshing process is sent from the threshing unit 5 to the tank 9 where it is stored and discharged to the outside of the machine by the discharging device when it is full.

ことができる。At the time of such work, if the tip of the culm sent into the handling room is in the proper position of the supply port 6, the state is maintained, but it is longer depending on the variety and cultivation area (long culm). Since there are some and short ones (short culm), it is necessary to make the length of the tip of the tip from the sandwiching position of the automatic grain culm feeder 8 substantially constant. For example, in the case of a long culm, when the supply adjusting means such as a switch or a supply depth sensor is operated to the shallow handling side, this operation activates the adjusting means such as the supply adjusting motor 15 as a drive source. Since all of the harvested grain culm transporting means (may be a part of the transporting means) is swung to the shallow handling side, before the grain stalks are started to be sandwiched by the automatic grain stalk feeder 8, the tips of the grain stalks are started. The section is repositioned to approach the automatic grain culvert feeder. That is, it is possible to reduce the supply depth and supply the grain culms to the threshing unit 5 at an appropriate position.

穀部５に適正な位置に供給することができる。On the contrary, in the case of the short culm, when the supply adjusting means such as the switch and the supply depth sensor is operated to the deep handling side, the operation adjusts the supply adjusting motor 14 or the like which is the drive source. Since the means operates to swing all of the harvested grain culm conveying means (may be a part of the conveying means) to the deep handling side, before the grain culm is started to be clamped by the grain culm automatic feeding device 8, The tip of the culm is repositioned away from the automatic grain culm feeder. That is, it is possible to increase the supply depth and supply the grain culms to the threshing unit 5 at an appropriate position.

Since the structure of the reaping unit 7 is simple and compact, the convenience of installation is improved even in a small space below the cutting culm transporting means. Further, the wind generated by the driving of the blowing means is sent to the lateral side and formed in the space portion 15 surrounded by the cutting culm conveying means, the flat plate 13, the entrance funnel 12, and the lower front wall portion 5b of the threshing portion 5. Since it flows into the air passage 16 and hits the supply adjusting motor 14 looking into the air passage 16, the supply adjusting motor 14 is prevented from being overheated and the straw debris that falls in the course of being conveyed is supplied. It is possible to prevent stagnation on the adjustment motor.
