Description

[0001]
BACKGROUND OF THE INVENTION
TECHNICAL FIELD The present invention relates to a processing apparatus for re-threshing a second thing discharged from a second catcher when selecting a threshing in a combine threshing machine or a stationary threshing machine.
[0002]
[Prior art]
In general, the second product discharged from the second receiving bowl is reduced and processed by a rocking selection mechanism for threshing, but this method cannot thresh the second product again. Therefore, recently, as described in, for example, Japanese Utility Model Publication No. 62-184420, etc., the second thing discharged from the second receiving bowl is sent to the handling room and threshing in this handling room is performed. Either threshing again with a handling cylinder, or, for example, as described in Japanese Utility Model Publication No. 3-91733, etc., sent to a processing cylinder provided separately from the handling cylinder, and with this processing cylinder I try to thresh again.
[0003]
[Problems to be solved by the invention]
However, in the former case, conventionally, the end of the second product reduction transfer means from the second product receptacle is connected to the handling chamber so as to directly communicate with the handling chamber. In the handling chamber, a strong wind is generated by the rotation of the handling cylinder, and this strong wind prevents the second product from being introduced into the handling chamber. In addition, there is a large risk of clogging due to the second item, and the second item's reduction port to the handling chamber is provided in a portion close to the dust outlet from the handling chamber, so the second item is There was a problem of discharging from the treatment room while being sufficiently threshed by the treatment cylinder.
[0004]
In addition, in the latter case, providing a processing cylinder separately from the handling cylinder not only complicates the structure of the threshing machine, but also causes a significant increase in size and weight, as well as loss of power. There was also a problem of increasing.
[0005]
This invention makes it a technical subject to provide the 2nd processing apparatus which eliminated these problems.
[0006]
[Means for Solving the Problems]
In order to achieve this technical problem, the present invention

"
It was configured as follows.
[0007]
[Operation and effect of the invention]
In this way, there is provided a second item feeding and transferring means for transferring the second item inherited from the end of the second item transferring means toward the inlet of the culm along the cereal transfer direction by the feed chain. Thus, since the second thing can be fed into the handling chamber from the grain shed entrance into the handling chamber by the second thing feeding and transferring means, it is ensured that the second thing is smoothly returned to the handling chamber. In addition, it is possible to reliably reduce the possibility of clogging with the second product when the second product is returned to the handling chamber.
[0008]
In addition, the second item is reduced to the entrance of the cereals into the handling chamber, and the cereal entrance to the handling chamber is located at a location far from the dust outlet from the handling chamber. The processing of an object can be reliably performed using a handling cylinder for threshing without providing a processing cylinder for that purpose separately from the handling cylinder as in the conventional case.
[0009]
In addition, by providing the second article feeding and transporting means at the tip side of the cereal head to be transported by the feed chain on the top surface of the cereal supply guide plate, it is transported into the handling chamber by the feed chain. The sawdust etc. separated from the tip of the grain straw can be fed into the handling chamber together with the second thing by the second thing feeding means, and the tip of the grain straw is placed on the upper surface of the grain straw supply guide plate. It is possible to reliably prevent accumulation of sawdust and the like separated from.
[0010]
Therefore, according to the present invention, the threshing treatment of the second item is continuously and reliably achieved without causing a complicated structure, and consequently an increase in size and weight, and an increase in power loss. In addition, the second threshing process can be used to reliably reduce the occurrence of clogging due to swarf or the like at the cereal entrance to the handling room.
[0011]
In particular, when the second thing transferred by the second thing transporting means from the second thing receiving bowl is inherited to the second thing feeding and transferring means from the end of the second thing transporting means, As described, the connecting portion of the second article feeding means to the end of the second article transferring means is located at a position substantially the same height as the end of the second article transferring means, or By being located at a position lower than the terminal end, the above-mentioned second item can be inherited reliably and smoothly, and there is an advantage that the occurrence of clogging in this portion can be reliably reduced.
[0012]
According to a third aspect of the present invention, the second article feeding means is configured in a screw conveyor having a rotating screw blade shaft, and the tip of the cereal cocoon transferred to the screw blade shaft by a feed chain. The tip of the cereal cocoon transferred by the feed chain can also be transferred in the direction of the handling room by the second item feeding means, in other words, the grain by the feed chain. In addition, it is possible to reliably reduce the occurrence of disturbance in the transport posture due to the delay in the transfer of the tip.
[0013]
In this case, as described in claim 4, the diameter of the tip of the screw blade shaft is reduced to a taper taper so that the screw blade shaft has the same diameter as compared with the entire screw blade shaft. The tip of the blade shaft can be brought closer to the handle cylinder in the handling chamber, and the above-mentioned effect can be further promoted, and the grains contacting the screw blade shaft can be reliably swung away around by the centrifugal force. Can be reduced.
[0014]
Further, as described in claim 5, when the screw blade shaft is viewed from the axial direction of the barrel, the head of the cereal that contacts this is rotated in a direction to press against the cereal supply guide plate. By doing so, it is possible to reduce the scattering of the grain around the tip of the second and cereal buds by contacting the screw blade shaft, and to remove the swarf adhering to the tip of the cereal from the tip of the screw blade shaft. There is an advantage that can be positive.
