I have.

The threshing machine 1 having the above-described second deep-frying cylinder 9 of the present invention configured to threat the harvested culm by the handling cylinder 2a in the handling room 2 and to remove threshed thresh from the harvesting culm. Sorting processing can be performed through the swing sorting body 5, and the waste culm can be discharged outside the machine via the feed chain 2F and the waste culm chain 2H to continuously perform threshing work. Also, of the threshed that has been sorted out as described above, the first is the first gutter 7.
a and the second bin is sent from the second gutter 70 to the second bin 9 in the middle of the freighting cylinder 7c. While performing, it is reduced and released from the return port 90 onto the oscillating sorter 5 by the discharge blade plate 13, and the sifting by the oscillating sorter 5 can be performed smoothly and accurately without giving excessive force.

That is, the second product fed to the second fryer cylinder 9 is quickly lifted in the support cylinder 91 with the rotation of the spiral body 10, so that it is transferred from the second gutter 70. Can be performed accurately. The second product to be pumped is the processing tube 92
The working surface of the helical plate 12 of the helical body 10 while temporarily receiving a convection action in the processing chamber 9S enlarged by the gentle inclined wall 93a formed on the inner bulging wall 93 and gradually expanding upward. And the centrifugal force of the processing piece 15 protruding on this action surface,
It is to be pumped toward the inner wall surface while repeating throwing and pumping.

Accordingly, the second product (the second product of the baby nodule) sent from the support cylinder 91 side in the form of a baby nodule is gently and gradually loosened between the bulging wall 93 formed in the processing cylinder 92 and the spiral body 10. can do. Accordingly, in the processing chamber 9S formed in the portion of the bulging wall 93, the second nodule in a lump is rapidly released, so that it is buffered and loosened without causing an impact load or clogging. The second product in the state can be circulated and retained in the processing chamber 9S to facilitate the separation of the debris and the grains in the second product.

The steeply-inclined wall 93b formed on the upstream side of this portion acts to provide braking so as to suppress the unprocessed second item in the processing chamber 9S from being lifted.
The loosening process with the spiral 10 is further promoted. At this time, the processing piece 15 (processing blade) provided on the working surface of the spiral plate 12 of the spiral body 10 vigorously throws in the outer peripheral direction while stirring and loosening the second object on the working surface of the spiral plate 12. At the same time, it is possible to efficiently perform the loosening process by the rotation and the stay.

As shown in the drawing, the processing piece 15 is provided with a narrow piece portion 15a on the spiral shaft 11 side and a wide piece portion 15b connected to the tip portion side, so that the centrifugal force is small. On the shaft side, the second object climbs over the narrow piece portion 15a and is allowed to move freely, thereby allowing the spiral shaft 1 to move.
1 can be prevented from becoming wrapped around and excessive rotation resistance, and can be prevented from having a large centrifugal force.
In 5b, the stirring and the throwing are performed accurately, and the loosening process is performed favorably with the processing tube 92.

A resistance piece 9 protruding from the inner wall of the processing cylinder 92 is provided.
4 is 2 for the second thing pumped by the spiral 10
Since the upward movement is restricted by giving a resistance in the lifting direction to the goods, the loosening processing of the second goods is performed with sufficient time between the spiral plate 12 and the small grains and branch spikes. The grains can be efficiently separated to make the grains into single grains.

In this case, if the resistance piece 94 is inclined and protruded in a direction opposite to the spiral direction of the spiral body 10 as shown in the illustrated example,
The upward movement of the second product can be further restricted, and the second product can be satisfactorily loosened between the intersection of the resistance piece 94 and the spiral plate 12 so that the grain in the second product can be obtained. Can be promoted into single grains. Therefore, the second item having the property of being wet or having a lot of wastes is satisfactorily unraveled without causing clogging or the like in the second fried grain 9, and the re-sorting by the rocking sorter 5 is smoothly performed. There is an advantage that it can be performed with high accuracy and that the length of the second flour cylinder 9 can be freely set.

[0023]

According to the first aspect of the present invention, when the second product fed to the second fryer is lifted on the working surface of the spiral plate by the rotation of the spiral body, the processing piece set up on the working surface is removed. It is possible to separate the debris and grains by rotating and agitating it while bouncing the second product in the middle of the freight in the outer circumferential direction by centrifugal force, and to return it to the sorting unit to perform good sorting of the second product. it can.

At this time, since the treated piece provided on the spiral plate is formed in the narrow piece portion on the spiral shaft side, an excessive rotation resistance is generated on the shaft portion having a small centrifugal force, and a large grain is generated on the grain. It is possible to loosen the No. 2 material while preventing damage and catch the No. 2 material by the wide piece formed at the tip, and to promote the separation of debris and grains while throwing it. You can do it.

According to the second aspect of the present invention, the resistor protruding into the cylindrical body at an inclination opposite to the spiral direction of the spiral body facing the resistor body allows the second plate to be transported by the spiral body to the spiral plate. A good loosening action can be given between the two, the separation of the debris and the grains can be promoted, and the sorting in the swing sorting section can be performed well. According to the third aspect of the present invention, the processing object provided on the spiral body causes the second object to jump to the outer periphery, and is further carried around among the plurality of resistors protruding from the cylindrical body, so that the resistor, the spiral body, and the processing piece Thereby, the loosening action can be performed favorably. Therefore, it is possible to smoothly promote the separation of the second waste and the grain.
