  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In FIG. 1 and FIG. 2, 1 is a general purpose combine, Comprising: The general purpose combine 1 is the cutting part 2 which cuts off the stem pod, and the threshing part 3 which threshs and sorts the grain from the stem cocoon thrown into the whole basket. , A grain tank 4 for storing the selected grain, a discharge auger 5 for discharging the grain in the grain tank 4 to the outside of the machine, a post-processing unit 6 for post-processing the threshed waste, and operation A driving unit 7 on which a person gets on and a crawler type traveling unit 8 are provided.

  The cutting unit 2 includes a header 9 that is connected to the front end of the machine body so as to be able to move up and down, a divider 10 that weeds uncut stems at the front end of the header 9, a cutting blade 11 that cuts off uncut stems, A reel 12 for scooping the cut stem and the cut stem, an auger 13 for collecting the scraped stem to a predetermined position in the width direction, and transporting the stem to the threshing unit 3 by the auger 13 And the feeder 14 which throws all the straw into the threshing part 3 is comprised.

  As shown in FIG. 3, a cutting height sensor 15 is provided at the bottom of the cutting unit 2 to detect the cutting height of the stalks by the cutting unit 2. The cutting height sensor 15 of the present embodiment includes a pair of left and right grounding type detection bodies 16 that rotate up and down according to the cutting height, and a potentiometer 17 that detects the rotation angle of each grounding type detection body 16. The detected value is used in automatic cutting height control for automatically controlling the cutting height of the cutting unit 2. The automatic cutting height control in the general-purpose combine 1 is usually effective when harvesting beans and is not used when harvesting rice or wheat.

  That is, when cutting the beans, if the cutting unit 2 thrusts into the ground, mud is cut together to cause dirt, so automatic cutting height control is used to avoid this. And since the field of beans has cocoons, a wide grounding type detector 16 is used.

  On the other hand, it is possible to use automatic cutting height control even when harvesting rice or wheat, but because the ground contact detector 16 is wide, it is difficult to detect cutting height with high accuracy in contact with the remaining crop. For some reason, the automatic cutting height control is rarely used for harvesting rice and wheat. Therefore, the use / non-use of the automatic cutting height control can be used as a crop discrimination element.

Further, it is a swing assembly provided with a grain sieve 32 for screening and is reciprocally swung continuously at a predetermined cycle by a swing mechanism (not shown).

  As shown in FIGS. 5 and 6, the chaff sheave 31 includes a plurality of fins 31 a arranged in parallel at a predetermined interval in the front-rear direction. Each fin 31a is inclined in a front-rear and a rear-high state, and the sorted matter is caused to leak from the gaps between the fins 31a while the sorted matter is transferred rearward as the swinging sorter 25 swings. The sort that has leaked here is collected as the first item via the Glen sieve 32, and the sort that has not leaked is collected as the second item. Each fin 31a is configured to be able to rotate back and forth with the upper end side as a fulcrum, and is connected to a fin drive motor 34 via a cam mechanism 33, and each fin 31a is driven by the fin drive motor 34. The gap (fin opening) between the fins 31a in the chaff sheave 31 can be changed based on the angle change of 31a. Then, by performing automatic sorting control for automatically increasing / decreasing the fin opening according to the amount of the sorted matter (detected value of the sorted matter amount detecting means), the amount of the sorted matter leaked from the chaff sheave 31 and the second reduced sort. The balance of the quantity is made appropriate, and it becomes possible to perform a highly accurate sorting process.
