[0002]

2. Description of the Related Art Conventionally, this type of threshing apparatus has a structure for transporting a processed material, as disclosed in Japanese Patent Application Laid-Open No. 9-308366, for example. A single screw-type transfer device for collecting the first material as a screw-type transfer device for laterally feeding objects,
It is known that a single screw-type transfer device for collecting the second material is arranged, and the transfer end of the screw-type transfer device for collecting the first material is processed into a grain recovery device such as a Glen tank. A lifting apparatus for lifting the articles is provided, and a lifting apparatus for returning the second articles to a swing sorting apparatus or the like is provided at a transfer end portion of the screw-type conveying apparatus for collecting the second articles.

[0003]

Therefore, in the above-mentioned transported structure of the threshing apparatus, a screw-type transporting device for transporting the threshing processed material is used in each of the first and second product recovery devices. Since it consisted only of a single screw conveyor, if the threshing amount was larger than usual, there is a risk that the conveying capacity of the screw-type conveying device may be exceeded. However, since the screw-type transfer device is driven even during the stay, the pressing contact action of the screw body on the grains and the like in the processed material acts to reduce the grains. There has been a high risk of damage.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and is directed to a threshing apparatus capable of increasing the conveying capacity so that the threshing product can be satisfactorily fed laterally even if the amount of the threshing product is larger than usual. It is an object of the present invention to provide a workpiece transport structure.

Is nearly twice that of a single screw conveyor. Therefore, the amount of transported material increases,
For example, even when the processed material overflows in the front screw type transport device, the overflowed processed material moves to the rear screw type transport device side and is transported by the rear screw type transport device. It should be noted that in order to increase the transfer capacity to about twice by using a single screw-type transfer device, it is conceivable to double the transfer speed or increase the screw diameter. In the case of, there is a disadvantage that the transported grain is easily damaged by the high transport speed, and in the latter case, the upper part of the screw may interfere with the wind path of the sorted wind, and the sorted wind may be disturbed. For example, there is a possibility that a problem that the sorting function is reduced due to the suppression is caused. On the other hand, by arranging the screw-type transfer devices adjacent to each other in front and rear as in the configuration according to claim 1 of the present invention, while the transfer speed in each screw-type transfer device can be maintained as before, It is not necessary to use a large-diameter screw that hinders the air path of the sorting wind.

In other words, the leakage amount of the processed material from the swing sorting device generally increases toward the front side, and the front screw type transport device receives the processed material from the front side of the swing sorting device. Therefore, the transport amount of the processed material is larger than that of the screw-type transport device on the rear side,
It is desirable that the route on which the processed material shifts to the lifting device from the front screw type transport device can be more easily shifted than the route on which the processed material shifts to the lifting device from the rear screw type transport device. By providing a transmission mechanism to the lifting device that may be in the way of the transfer route in the rear screw-type transport device, the transfer of the processed material from the screw-type transport device to the lifting device as a whole is possible. The occurrence of problems such as clogging is suppressed and smooth operation can be performed.

(Structure) According to a fifth aspect of the present invention, there is provided a threshing apparatus transported structure of a threshing apparatus according to any one of the first to fourth aspects, wherein a rear side of the double screw type transport apparatus is provided. The screw diameter of the screw-type conveying device is set to be larger than the screw diameter of the front screw-type conveying device.

(Operation) According to the configuration of the fifth aspect of the present invention, generally, the bottom of the sorting chamber constitutes a guide portion for guiding the sorting wind from Karamino toward the rear. In addition, since the air path is set to be upward toward the rear, the guide section is configured on an inclined surface that is higher at the rear. Is provided at the lower part of the air flow path, that is, at the bottom of the air flow path by Karino, so as not to hinder the air flow, and thus, in such a state, it is possible to further enhance the lateral feed performance of the processed material even to some extent. for,
Even if the screw diameter of the screw transfer device on the rear side of the screw transfer devices arranged side by side is set to be larger than the screw diameter of the screw transfer device on the front side, the screw transfer device on the rear side of the screw transfer device It will be possible to prevent the screw body from interfering with the airflow path of the sorting wind from Karamino.

(Effects) Therefore, according to the configuration of claim 5 of the present invention, the conveying capacity of the thresh-processed material is set to be larger than the screw diameter of the front screw-type conveying device on the rear screw-type conveying device. Even if it is increased, the screw body of the screw type transfer device on the rear side can be in a state that does not hinder the sorting wind of Karamin, so that the processing material transfer capacity can be further increased, but the sorting capacity The reduction can be suppressed.
