である。 This invention is designed to prevent dust from leaking from the mesh when the bottom of the processing chamber is made into a gutter with a screen large enough for grains to pass through, and when the screening air is blown through the lower side of the processing chamber in which the screw conveyor is installed. This eliminates the phenomenon in which dust adheres to the back side of the screen due to the sorting wind and prevents it from smoothly discharging to the outside of the machine, which adversely affects the sorting action.Furthermore, the sorting action is further improved by allowing the wind sorting action to take place inside the processing room. This was proposed in an attempt to improve it.

は合流して機外に排出される。 Therefore, when the machine moves forward, the standing grain culm is tilted backward by the rotating reel 1, and the culm base is harvested by the cutting blade 2, and the one on the right side is transferred to the left by the spiral of the guide 3 and harvested on the left side. It joins up with the other feeders and is fed into the feeder house 4 by the scooping rod 3a. The fed grain culm is sent to the front part of the handling chamber B by the grain culm transporting body 5 which rotates in the direction shown by arrow A, and is forcibly transferred to the rear inside the handling chamber B by the spiral body 7c. The long culm pieces and some straw waste that have been thrashed are discharged from the handling chamber B side of the suction and dust removal chamber 8 without passing through the receiving net 11, and unprocessed items such as grains and ears are removed. Dust such as straw waste is caught in a relatively large mesh net 1
1 and fall into processing chambers D and D', respectively.
In this case, some of the objects are caught by the rectifying plates 16 and 16a and fall from the lower end, while others enter the processing chambers D and D' directly, but all of the objects are sorted by blowing out the sub-sorting filters 19 and 19a. The dust is removed by the wind and the removed dust is blown backwards. The grains from which dust has been removed are transferred to screw conveyors 14 and 14 in each processing chamber D and D'.
The bottoms of the meshes 13, 13a are directed backward by the meshes 14a, and the grains and the fine dust generated there leak through the meshes 13, 3a, and unprocessed items such as ear cuts are threshed and straw waste is removed. The whirlwind blades 20, 20a are moved rearward and rotated in the direction of the arrow B, and are jumped up to meet in the center. The grains and fine dust leaking from the meshes 13 and 13a are sorted by the selection section air which is blown through the main sorting air passage 17 by the air pressure winnower 18 and the suction dust removal impeller 9. The grains are taken out from the first drain gutter 21
The second material is taken out of the machine from the second material take-out gutter 22, and the fine dust is sent through the main sorting air passage 17.
On the way, the fine dust is transferred to the whirlwind blades 20, 20a.
The feeding action is further enhanced by the whirlpool blades 20, 2.
The straw thrown up by 0a and the dust coming from the processing chambers D and D' join together to form the end part 1.
It is sucked into the dust suction port 8b side of the suction dust removal chamber 8 from 7a and discharged outside, and finally joins with the long culm pieces and some straw waste discharged from the handling chamber B side of the suction dust removal chamber 8. and is ejected from the aircraft.

向上させることができる。 As explained above, the present invention provides an axial flow threshing machine in which a wind sorting section that blows the wind for sorting materials in the axial direction of the handling barrel is disposed below the handling chamber. The bottom part is made into a gutter-like structure with a mesh that allows the grains to pass through, and a processing chamber with a screw conveyor inside is inserted, and the dust exhaust side of this processing chamber is open and the entire width of the processing cylinder is An opening is provided across the opening, and a current plate is provided obliquely from above the opening to diagonally downward above the screw conveyor, and the opening at the bottom of the current plate communicates with the end of the main sorting air path through the inside of the processing chamber. Therefore, the dust that falls into the processing chamber through the receiving net that forms the handling room along with the materials to be handled is removed by the wind separation effect in the processing room. Processing efficiency is improved because all grains are processed inside the processing chamber, and only the grains and fine dust generated inside the processing chamber leak out from the processing chamber, reducing as much as possible what sticks to the back side of the bottom of the processing chamber. This can further improve the sorting effect.
