Since the wind blows in the direction, it is normally clockwise (see arrow A in FIG. 1) in a side view. On the other hand, the rotation directions of the first spiral body and the second spiral body are the same as those of the different types of threshing machines and the relationship with other drive devices in the threshing machine (such as a suction fan and a cutter) and other power transmission systems. In many cases, the spiral is used counterclockwise (see arrow B in FIG. 1) in order to achieve dual use. That is, the rotation of the compressed air fan and the rotation of the spiral body are different from each other in the forward and reverse directions. In order to rotate and drive each spiral body and the compressed air fan from one drive source, a reversing device is provided. However, there has been a problem that a complicated device such as the above has to be provided, resulting in high cost, and that the space of the machine body cannot be effectively utilized.

In the above, a driving belt for driving a spiral is wound around the first spiral and the second spiral to be rotationally driven, and the plurality of compressed air fans are the first compressed air fan for selecting the primary wind and the first product wind. It is formed by a second compressed air fan for selection and a third compressed air fan for selection of a second product wind, and a transmission belt separate from the drive belt is wound around these compressed air fans in series to form a plurality of them. Of the compressed air fan, the drive pulley provided on the side of the compressed air fan is inserted between the first spiral body and the second spiral body, and is driven on the back side of the rotating action of the drive belt to thereby form the compressed air fan into the spiral body. It is configured to rotate in reverse and blow air As a result, the drive belt can precisely rotate and drive the first spiral body and the second spiral body having a large driving load, and the transmission belt, which is separate from the driving belt, has the first, second and third driving belts having a small driving load. It is wrapped around a wind fan,
The drive pulley is reversely driven with a sufficient winding angle on the back side of the rotation action of the drive belt between the first spiral body and the second spiral body, so that the first, second and third compressed air fans can be accurately rotated. In addition to being able to perform good wind selection, it is possible to obtain inexpensive drive for both forward and reverse rotation with a simple structure without providing a complicated reverse rotation gear case or the like for reversely transmitting the plurality of compressed air fans. be able to.

せることを可能にすることができる。In addition, since the first, second, and third compressed air fans are rotatably driven by winding the transmission belt separately from the drive belt, the rotation speed of the first, second, and third compressed air fans can be adjusted according to the type of grain removal or the generation of waste. When it is desired to change, the rotational speed of a plurality of compressed air fans can be efficiently and easily changed and adjusted simply by adjusting the effective diameter of the pulley of the compressed air fan wound around the drive belt. be able to.

とができる。In addition, the first compressed air fan for primary air selection blows the selected air to the chaff sheaves in advance, and the second compressed air fan blows the selected air directly to the Glensieve to select the first and second products. Since the dust is exhausted by the third compressed air fan, the plurality of compressed air fans facilitate the rearward transfer of the object to be processed, and the good sorting of the first and second products. It is possible to provide a high-efficiency thresher capable of threshing a large amount of grain culm.
