2. Description of the Related Art A wind selection chamber is provided at the rear of the handling cylinder in the axial direction,
In a threshing machine in which a swinging sorting body is slidably swingable in the front-rear direction in a sorting air passage formed from the lower front of the handling cylinder toward the wind sorting chamber, the second thing separated and sorted from the first one is A second spiral shaft is used to convey laterally to the lower end of the second reduction cylinder, and a second lifting spiral shaft returns to the swing sorting body for re-sorting.

[0003] However, in the transmission system of the conventional second reduction device, power is transmitted from the Karamin shaft via a sorting belt for the second spiral shaft, but the power is transmitted to the second spiral shaft for the second lifting shaft.
A driven sprocket shaft that supports a drive sprocket provided at the end of a second helical shaft that is supported through the outer wall of the second reduction cylinder and a bevel gear located in a gear case formed at the lower end of the second reduction cylinder. Are linked by a chain, and the bevel gear is meshed with a bevel gear in a gear case that is rotatably supported at the lower end of the second lifting shaft to rotate the second lifting shaft. For this reason, the transmission of power to the second lifting shaft cannot be complicated, and even when transmitting power from the second spiral shaft to the suction fan, the suction fan is connected to the input pulley of the second spiral shaft. Since it is necessary to arrange the transmission belt on the rear side, the operation of suspending the transmission belt from the second helical shaft to the suction fan is hindered by the selection belt or the like, and there is a problem that it cannot be easily performed.

[0004]

SUMMARY OF THE INVENTION In view of the above situation, the present invention has been made to solve the conventional problems, and in particular, from the second spiral shaft to the second lifting shaft. Simplifies the transmission of power and allows the suction fan to be arranged in the direction opposite to the input pulley side of the second helical shaft, so that the work of suspending the transmission belt from the second helical shaft to the suction fan is selected. It is an object of the present invention to provide a second reduction device in a threshing machine which can be easily performed without being hindered by a belt or the like.

[0005]

Means for Solving the Problems To solve the above-mentioned problems, the technical means adopted in the present invention has a wind selection chamber at the rear of the handling cylinder in the axial direction, and the wind selection chamber is provided from the lower front of the handling cylinder to the wind selection chamber. A rocking sorting body is erected in the sorting wind path formed to swing freely in the front-rear direction, and is provided by a pressure wind from Karino arranged below the rocking sorting body .
The straw waste and the like supplied to the wind selection chamber by a suction fan
In a threshing machine configured to discharge to the outside of the machine, a second product lifting spiral shaft provided in a second reduction cylinder for reducing the second product to the rocking sorter, and a lower end portion of the second product in the second reduction cylinder. And the second spiral shaft which is laterally conveyed to the side is interlocked and connected orthogonally via bevel gears which are supported on the respective shafts.
Through the bevel gear and outward from the bevel gear shaft support
To form an extension shaft portion, and a drive provided on the extension shaft portion.
Connect the pulley and the passive pulley provided on the rotation axis of the suction fan.
It is characterized by being dynamically connected .

[0006]

Therefore, according to the present invention, the second spiral shaft and the second lifting shaft are interlockingly connected to each other via the bevel gears which are pivotally supported. The transmission of power to the upper helical shaft is simplified, and the horizontal transfer of the second product by the second helical shaft and the return of the second product to the swing sorting body by the second lifting helical shaft are performed smoothly. Further, since the second helical shaft extends laterally from the shaft support portion of the bevel gear, it is possible to interlock and connect the suction fan to the extended shaft portion. The work of suspending the transmission belt to the fan can be easily performed.
