(Problems to be Solved by the Invention) The known threshing room has a threshing chamber supply port which is wide open to the left and right with respect to the front-rear axis, one of which is a rotation-up side supply port, and the other is a rotation-down side supply port. However, there is a problem in that the grain culm is supplied in the same manner to the rotation-up side supply port and the rotation-down side supply port.

In other words, in the case of the above-described configuration, at the rotation ascending side supply port, a relatively large amount of grain stalks are scraped by the rotation of the spiral blade start end constituting the screw of the handling cylinder to the ascending side, but the rotation ascending side supply is At the mouth, the amount of scraping due to the rotation of the spiral blade leading end to the descending side is small.

Although there is a difference between the two as described above, in the known example, the grain culm was supplied to the rotation-up side supply port and the rotation-down side supply port in the same manner. Was done.

As shown in FIG. 3, the starting end of the spiral blade 9 is rotated upward by the spiral blade 9 at the rotation-up side supply port A, as shown in FIG. Grain stalks are relatively abundantly scraped well,
In this case, since the amount of scraping is small due to the rotation of the start end of the spiral blade 9 toward the descending side, if the grain stalk is supplied in the same manner, the supply port A on the rotation up side becomes insufficient and the supply port on the rotation down side. In B, a clogging phenomenon is observed, and the supply efficiency is reduced.

Therefore, the conveyance speed of the rotation-up side supply port transfer section 27 is made faster than that of the rotation down-side supply port transfer section 28, and a large amount of grain is supplied to the rotation up-side supply port A side from the rotation down-side supply port B side. In addition, the efficiency of supply into the threshing room 6 is improved.

Right rotating bodies 38 and 39 are provided on the upper right rotating shaft 36 and the lower right rotating shaft 37, respectively, and the right endless belt 40 is hung between the right rotating body 38 and the right rotating body 39, and the right endless belt 40 is predetermined. A plate-shaped right carrier 41 is attached at intervals of.

Reference numeral 42 denotes a bearing member for the rotating shafts 30, 31, 36, and 37 provided in the transport cylinder 21.

Power from the body side is separately transmitted to both the upper left rotation shaft 30 and the upper right rotation shaft 36, and the upper left rotation shaft 30 is rotated faster than the upper right rotation shaft 36.

A left input gear 43 is fixed to the upper left rotation shaft 30 and a right input gear 44 is fixed to the upper right rotation shaft 36.
Means for making the diameter smaller than that of the right input gear 44, or the transport mechanism 26 is constituted by a single transport section 27, and the end of the endless belt of the transport section 27 has a rotationally increasing side supply port A rather than a rotationally descending side supply port B.
A configuration in which a number of transport bodies are provided with a narrow interval on the side may be used.

(Operation) Next, the operation will be described.

Since the present invention has the above-described configuration, to explain in the example of combine, when the body is advanced, weeding is performed by the weeding body 15 of the reaper 4, and the stalks are scraped by the scraping reel 16,
The root of the culm is cut with the cutting blade 17 and the culm is scraped with the reel 16
To the auger 18, and the grain culm is joined to the discharge port 24 by the auger 8.

The front end of the transfer tube 21 of the transfer elevator 20 is attached to the discharge port 24, and a transfer mechanism including a pair of right and left rotation-up side supply port transfer sections 27 and rotation-down side supply port transfer section 28 in the transfer tube 21. 26 is provided, and a rotation rising side supply port transfer section 27 is positioned on the rotation rising side supply port A side of the threshing room supply port 25 of the threshing room 6 of the threshing apparatus 3, and the rotation descending side supply of the threshing room supply port 25 is provided. The transport unit 28 for the rotation-supply-side supply port is positioned on the port B side, and the transport unit 27 for the rotation-up-side supply port is moved from the rotation-down-side supply port transport unit 28
Therefore, the transport mechanism 26 supplies more grain to the rotation-up side supply port A side than the rotation-down-side supply port B side of the threshing chamber supply port 25.

That is, the upper left rotation shaft 30 of the rotation-up side supply port transfer section 27.
Rotates, the left rotator 32 rotates, and the left rotator 32 and the left rotator
The left endless belt 34 hung between the horn 33 rotates, and the plate-shaped left carrier 35 rotates the grain stalks collected at the discharge port 24 of the reaper frame 23 to the rotation of the threshing room supply port 25. It is transported and supplied to the side supply port A side.

Upper right rotation shaft 36 of the other rotation lower side supply port carrier 28
Rotates, left rotating body 38 rotates, right rotating body 38 and right rotating body

Transports and feeds the cereal stems collected at the discharge port 24 of the reaper frame 23 to the rotation descending side supply port B side of the threshing room supply port 25, but the input from the machine body side is upper left than the upper right rotation shaft 36. Since the rotating shaft 30 is rotated faster, the left transport body 35 moves faster than the right transport body 41, so that more of the threshing chamber supply port 25 has a higher rotation-side supply port A side than a lower rotation-side supply port B side. Supply cereals.

Therefore, the supply port A on the rotation rising side of the screw-type handling cylinder 7
In this case, a large amount of grain stalks are satisfactorily scraped into the threshing chamber 6 by rotating the start end of the spiral blade 9 upward, thereby eliminating the supply shortage.

And, in the rotation lowering side supply port B, the rotation rising side supply port A
As the amount of cereal stem supply is smaller than that of, the clogging phenomenon is prevented.

Thus, the cereal supplied from the threshing room supply port 25 to the threshing room 6 is threshed, air-selected in the wind-selection room 11, and processed.
