Therefore, according to the first aspect of the first invention, the degummed material thawed in the threshing room is dropped on the swinging sorting body, and the swinging action of the swinging separator and the lower side of the swing selector are moved toward the longitudinal end side The blowing wind is selected by using it together. In this case, the auxiliary blower blows air between the supply chain and the tongue fan case toward the longitudinal end so that wind is blown between the respective pins, and the wind passes through the lower side of each pin, and is installed separately from the tongue fan The auxiliary air blowing device increases the air flow to the rice straw so that the separation of the grains and the dust can be easily performed.

In addition, the second means is that the air blown from the hot air passage of the engine is sucked into the wind tunnel of the auxiliary blower, and is blown toward the longitudinal side between the supply chain and the tug fan case as described above, The heat is concentrated and the fin itself is heated to accelerate the drying of the toned material, so that the selection is further improved.

In addition, according to the third means, the wind generated by the tuyeres is classified into the sorting air passage and blown out from the discharge port toward the end side between the threshing chamber and the starting end of the shaking sorting element, And the preliminarily selected ones are selected by using the rocking action of the rocking separator and the wind flowing from the rocking fan to the lower side of the rocking separator. At this time, when the intermittent sensor for detecting the presence or absence of the supply interstices in the threshing chamber detects "no ", as in the case where the gas turns U, the wind classified as the selective wind tunnel from the tumbling fan is switched to the blowing wind tunnel side, And is blown into the threshing compartment from the intermittent supply port so that there is no scattering of the third time and no dust is generated from the intermittent supply port.

In order to provide the balloon device capable of improving the sorting performance by achieving the above-mentioned object in the combine threshing portion described above, the present invention is characterized in that, as the first means, An auxiliary fan for blowing air toward the longitudinal end side between the tie plate fan casings is installed and a vent hole with an open / close valve is opened at a suitable place outside the throat sorting area of the auxiliary fan case. In addition, And an auxiliary fan for blowing air toward the longitudinal end side is interposed between a leading end side of the rocking selector and the tuyere case, Is provided in the wind tunnel to supply a part of the hot wind of the engine room to the auxiliary fan case through a wind tunnel for forcibly feeding by the radiator fan It will have to.

Therefore, according to the first aspect of the second invention, the grains subjected to the threshing treatment in the threshing chamber fall on the swing sorting body, and the swinging action of the swinging selector and the lower side of the swing selector are moved toward the longitudinal side It is selected by using the flowing wind together. In this case, the wind generated by the auxiliary fan blows air between the starting end side of the oscillating separator and the tie-off fan case toward the longitudinal end so that wind is blown between the respective pins, and wind passes under the respective pins, When the separation of the grain and the dust is good and the air flow to the rice straw is important by the auxiliary fan installed separately from the fan, the amount of the threshing water becomes small such as when the end of the cutting work is imminent, Quot; interlocking "operation, the opening / closing valve is opened to open the air outlet, so that the air generated by the auxiliary fan is discharged from the air outlet to the outside of the airframe, The wind that passes through it is weakened so that the grains do not scatter out of the gas.

In addition, the second means is that a part of the hot air flow in the engine room is fed into the wind tunnel installed in the engine room by the radiator fan and is supplied into the auxiliary fan case through the wind tunnel, The air is blown toward the end side between the fan and the tuyere fan case and the heat is concentrated in the blowing to the rice straw so that the fin itself is heated to accelerate the drying of the threshed product so that the selection is good and the overheating of the engine can be prevented .

On the other hand, in order to achieve the above-described object, a third invention of the present invention provides a threshing machine provided with a rocking selector below a threshing compartment, comprising a traversing portion for sucking the discharged dust from the trailing end side of the rocking selector, And a straw cutting machine for cutting the discharged straw of the threshing and finishing process is integrally rotatable, wherein the first means is such that the transverse fan is inserted into the lower side of the straw cutter to polymerize the transverse fan and the house cutter Wherein the edge of the trailing edge of the traverse fan has a height substantially equal to the height of the discriminating surface of the trailing edge of the trailing edge.
