Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a second reducing device for a thresher.

[0002]

2. Description of the Related Art As a transfer means for second reduction in a thresher, there are a transfer means using a thrower and a transfer means by an auger, but the transfer means by an auger is more efficient than the transfer means by a thrower. It can be seen more because it is advantageous in terms of certainty and the degree of freedom in setting the transfer route. In general, the transfer means for the second reduction by the auger is installed by connecting the inherited case part at the lower end of the tubular case containing the auger to the transfer end part of the second gutter. Then, the second product (incompletely processed product including undebris) sent from the second conveyor into the inherited case is simply lifted and transferred by the auger, and the upper end of the cylindrical case is transferred. It is configured to return from the outlet toward the handling room or the processing room or the sorting device section.

[0003]

Therefore, in the conventional second transfer means for reduction, the second object in the incompletely processed state, which is almost the same as when it is taken over from the second conveyor, is the handling room or the processing room. Since it is only returned to the required part of the above, the reduction of such a secondary product causes an excessive load on the handling cylinder and the like, which easily causes problems such as rotation drop and clogging. , There is a difficulty that the tendency becomes more severe in a combine thresher that processes wet materials, and further, when the second product is returned to the sorting device part, single grains mixed in the second product are sorted and leaked. However, since the particles with branch shoots are not removed, a vicious cycle occurs and the loss increases, and the fact that the absolute amount of the selected product increases increases the selection performance. There is.

[0004]

The present invention has been made for the purpose of solving the above-mentioned problems, and the following technical means are provided to achieve this object. That is, the second reducing device of the thresher in the present invention is a thresher for transferring and reducing the second product from the second conveyor to a required place by a transfer means by an auger, and a part in the transfer direction of the auger. Is formed by a handling tooth group that imparts a handling action to the second object while it is being transported, and a cutting blade is provided corresponding to the handling tooth group. And
It is preferable that the portion formed by the handling tooth group has a large diameter.

[0005]

The apparatus of the present invention is a thresher for transferring and returning the second product from the second conveyor to the required place by the transfer means by the auger, and a part of the second product is transferred in the transfer direction of the auger. It is formed by a group of handling teeth that imparts a handling action to it while transporting it, and a cutting blade is provided corresponding to the group of handling teeth. Grains were shredded, and long straw debris was also cut to reduce the occurrence of clogging during transfer, reducing the burden on the handling cylinder or processing cylinder, which is the reduction destination. And, the grain with branch shoots is shed during the transfer, and there is no problem even if the second product is returned to the sorting device part, so the residence time of the second product in the thresher is reduced by such reduction. It is possible to work with high efficiency by reducing the total amount. Further, when the auger portion formed by the handling tooth group has a large diameter, the peripheral speed is increased and a more effective handling action is performed.
