DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technology for providing a processing cylinder for processing a second product sorted by a swinging sorting device of a combine.

[0002]

2. Description of the Related Art Conventionally, in a self-contained combine,
The front side of the cut culm is guided into a threshing device, threshed by a handling cylinder, and the threshed rice is leaked onto a swinging sorting device below the handling cylinder, and further processed by the handling cylinder. The unattached spike sticking particles and ear cutting particles were transported into the dust outlet treatment cylinder, processed into grains and straw chips while being transported backward, and dropped again at the rear of the rocking sorter. . The grains dropped by the rocking sorting device are sorted by rocking sorting and wind sorting into the first, second, and straw waste, and the sorted first is stored in a Glen tank, Straw chips were discharged from the rear of the fuselage, and a second product was placed on the crimping net from the front side of the handling cylinder via a reduction conveyor and re-sorted. Similarly, in the case of the ordinary type combine, the second product after the sorting is configured to be re-introduced into the front part of the swinging sorting apparatus via the reduction conveyor or into the threshing unit for processing.

However, when a second material is further fed from the reduction conveyor into the handling cylinder, the processing space is further reduced, and sari grains are generated. In addition, the second material re-injected from the reduction conveyor to the handling cylinder side is processed on the handling cylinder side and leaked to the swing sorting device, or the second material left in the processing is the dust outlet processing cylinder. However, depending on the rice varieties, the elasticity of the branch spike of the grain is high, and it is not possible to remove the branch spike on the handling cylinder side, it is leaked downward as it is, and again In some cases, it was thrown into the handling cylinder side through a reduction conveyor, and it was not possible to reduce the number of second products. Even in the case of a normal-type combine, there is a case where it is not possible to reliably treat the spiked particles having high elasticity.
