In addition, the opening/closing shutter is characterized in that a ventilation hole for a ventilation fan is formed in the opening/closing shutter.

Effect of the invention Therefore, according to the invention, when performing maintenance and inspection work on the sorting section, the opening/closing shutter installed across the cleaning ports of the first gutter and the second gutter has openings corresponding to both cleaning ports. Since both cleaning ports are provided side by side, both cleaning ports can be freely opened and closed using only the integrally formed opening/closing shutter. During threshing, even if you close the cleaning ports of the first and second gutter with shutters,
Since the ventilation hole of the ventilation fan is formed in the opening/closing shutter, the ventilation path of the ventilation fan arranged between the first gutter and the second gutter will not be blocked by the opening/closing shutter, and the ventilation fan The sorting performance can be improved by raising the airflow, and by operating the opening/closing shutter with ventilation holes, the position of the ventilation hole can be moved and the amount of ventilation from the fan can be changed, so it can be adjusted to suit the work conditions. You can adjust the air volume by

Embodiment The embodiment of the present invention will be described in detail based on the attached drawings. 1 is a thresher, and handling teeth 5, 5... are installed between front and rear side plates 3, 4 forming a handling chamber 2. A handling cylinder 6 provided therein is axially mounted in the front-rear direction, and a grain culm feeding device 7 is installed along the handling opening of the handling chamber 2. Reference numeral 8 denotes a receiving net stretched over the outer peripheral surface of the handling drum 6, and a sorting section 9 directly below the receiving net 8 contains grains that have leaked through the receiving net 8;
A grain rocking sorter 10 for transporting and sorting straw waste and the like is installed in a direction different from the axial direction of the handling cylinder 6. Reference numeral 11 denotes a sorting air passage formed below the grain oscillating sorter 10, and a winnower 12 is disposed at the front base end of the sorting air passage 11. The side faces the wind selection chamber 13 formed at the rear of the handling cylinder 6.

14 is the first gutter provided below the grain oscillating sorter 10, and 15 is the second gutter provided behind the first gutter, in which the first spiral 14a and the second spiral 15a are respectively arranged. It is located between the first gutter 14 and the second gutter 15, and the upper side is the sorting air passage 11.
A blower fan 16 is provided which communicates with the air. 1
7 is the first gutter cleaning port provided at the bottom of the first gutter 14, and 18 is the second gutter cleaning port provided at the bottom of the second gutter 15. An opening/closing shutter 19 integrally formed across both cleaning ports 17 and 18 is attached to a bottom plate 20 of the sorting section 9 so as to be slidable in the front and rear directions. 21 is the first gutter opening formed in the opening/closing shutter 19 corresponding to the first gutter cleaning port 17, and 22 is the second gutter cleaning port 18.
A second gutter opening is provided correspondingly to the operating rod 2 connected to the rear end of the opening/closing shutter 19.
The cleaning ports 17 and 18 are opened and closed by sliding the opening/closing shutter 19 back and forth through the openings 3. The first gutter opening 21 is wide open toward the rear, and the center side of the opening/closing shutter 19 serves as a ventilation hole 24 that forms a ventilation path for the ventilation fan 16.

25 is a straw removal chain that conveys waste straw to the rear; 26
is a straw cutter.

In the above configuration, the grain culms fed into the handling chamber 2 by the grain culm feeding device 7 and transferred along the handling port are threshed by the rotation of the handling drum 6, and leak through the receiving net 8. The dried grains, ear-cut grain culms, straw waste, etc.
The grains fall onto a grain rocking sorter 10 installed in the sorting section 9. The fallen grains are then subjected to a twisting action caused by the rocking motion of the grain rocking sorter 10 and a wind-selecting action caused by the wind raising of the winnower 12, and the sorted grains are collected in the first gutter 14 and then The products are returned to the sorting section 9 through the second gutter 15. During the threshing operation, even if the first gutter cleaning port 17 and the second gutter cleaning port 18 are closed by the integrally formed opening/closing shutter 19, the ventilation hole 24 is open in the opening/closing shutter 19, so the ventilation fan 16 will not be blocked, and the sorting performance can be improved by raising the air from the winnowing machine 12 and the blower fan 16. Furthermore, if the opening/closing shutter 19 is slid through the operating lever 23, the ventilation hole 24 will be closed.
