Adjustment can be made to guide the dust on the gear box 9, and oiling and inspection can be performed without removing the handling cylinder shaft 7 from the gear box 9.

When the husk is fed into the handling chamber 5 from the supply port 1 by the pinching conveyance of the foot chain 18, it gets caught in the handling teeth 6' of the handling cylinder 6, is threshed in a low-grade method, and reaches the end of the handling chamber 5 before exiting. The waste straw on the side plate 3 is conveyed from the culm side by the foot chain 18 and discharged from the straw removal port 2 into the straw removal passage 23, and is suspended from the straw removal passage 2 with the tip side 11 facing downward.
3, during which the grains fall, enter the No. 2 conveyor 35, and are discharged outward from the discharge port 24. The waste straw is carried out by the straw waste cheno 25, as shown by the arrow in The grains are transported to the factory, where they are threshed and discharged.

The culms, etc. that have leaked through the crimp net 4 are oscillatingly sorted by the lower oscillating sorter C, fall while being sorted by the grain sorting plate 39, and are sorted by the pressure sorting wind to the No. 1 conveyor 44. to go into.

In addition, the dust circulating in the handling chamber 5 is guided by the guide plate 33', passes over the outlet side plate 3, flows from inside the cover B to the dust inlet 43, and when it falls, it passes through the oscillating sieve. The straw waste is sorted by the wire 42 and sucked into the suction port 37', and passed through the oscillating sieve wire 4.
Items that fall after being sorted by 2 are placed on the door-shaped sorting plate 3.
The grains sorted by 8 fall onto the grain sorting plate 39, fall onto the first conveyor 44, and are fed by the door-shaped sorting plate 38.
The second material that flows into the gutter 34 side and reaches the tip side of the oscillating sieve wire 42 and is not sucked into the suction port 37' flows down into the 112th gutter 34 and is returned to the handling chamber 5.

The grains entering the lifting cylinder 47 from the No. 1 conveyor 44 are lifted up and put into a paddy bag 51.

In this way, the present invention provides an axial flow threshing machine with a structure in which the handling chamber 5 and the sorting dust chamber A are arranged parallel to the foot chain 18 in front and back. Outlet side plate 3
is formed to protrude outward on the opposite side of the foot chain 18 to form a projecting shape on the outer side plate 27, and the side plate 22' of the sorting and dust removal chamber A is positioned inward than the outer side plate 27, A cutout space is formed at the rear of the handling chamber outlet side plate 3 on the lateral outer side of the sorting dust chamber side plate 22', and above the handling chamber 5 and the sorting dust chamber A, the inlet side plate 2 and the outlet side plate 3 are formed. The grain lifting cylinder 47 arranged near the corner of the notch space is covered with a single large cover B fastened to the sorting and dust removal chamber side plate 22', and the grain lifting cylinder 47 arranged near the corner of the notch space is connected to the outlet side plate 3 and the sorting and dust removal chamber side plate. 2
2' are supported and fixed by multiple stages of upper and lower supports 49, and a cutting blade stand 26 is provided in succession between the protruding parts of the entrance side plate 2 button and the exit side plate 3, thereby achieving the following effects. This is what led to this.

(a) The inlet side plate 2, the outlet side plate 3, and the sorting dust chamber side plate 22' are connected at the top by a single large cover B, and the outlet side plate 3 and the sorting dust chamber side plate 22'
Since the structure has a structure in which the corner portions between the two are connected by a plurality of upper and lower supports 49, the entire structure is extremely rigid and robust.

(b) The grain lifting cylinder 47 is installed relatively long in the vertical direction of the machine, and a large amount of grain is transported through it during operation, so it is possible for the base end to be subjected to a heavy load and be damaged. However, in this invention, the support metal 4 of the machine frame has a robust structure as described above.
Since it is supported at multiple locations above and below by 9, it is firmly held with good vibration resistance, and it can operate smoothly without straining the transmission part or generating abnormal noise.

(c) On the other hand, bending and twisting forces are applied to the cutting blade 26 due to the threshing load, and in the past, especially when threshing wet materials, the button may become deformed and damaged, or the handling chamber 5 may become clogged due to poor threshing. However, in the present invention, as mentioned above, such problems are resolved by installing the cutting blade 26 between the inlet side plate 2 and the outlet side plate 3 of the machine frame structure, which are firmly connected. Therefore, the threshing ability can be maintained well over a long period of time.

(d) By organically attaching the grain lifting tube 47 and the cutting blade base 26, which are subjected to heavy loads in the threshing device, to the machine frame, it is possible to provide a machine frame structure of the threshing device that is robust as a whole at a low cost. Moreover, the cutting blade stand 26 is compactly installed in the bulge of the handling chamber 5, and the grain lifting cylinder 47 is also installed in the corner of the notch space formed by the outlet side plate 3 and the sorting dust chamber side plate 22'. Because the threshing device is arranged in a compact manner, it can be installed compactly without increasing the width of the entire threshing device.
It becomes possible to sufficiently widen the space of the paddy receiving part connected to 7.
