DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a variable-teeth-handler having a variable number of teeth to be implanted on the peripheral surface of the handle. In particular, the present invention changes the transfer force of the tooth handling, which gives a transfer action from the supply side to the discharge side, to the thresh in the handling room, so that the residence time in the handling room can be freely lengthened and shortened, and threshing according to threshing conditions. The purpose is to improve the processing performance.

[0002]

2. Description of the Related Art As described above, teeth treated for threshing while giving a transfer action from the supply side to the discharge side of the thresh in the handling room are vertically planted on the peripheral surface of the handling cylinder and threshed. Transfer force was unchanged. Therefore, the threshing process action is affected by threshing conditions such as difficulty of threshing due to the difference in variety of threshing products and the degree of creature or degree of drying, and when threshing is difficult, unprocessed materials are discharged from the discharge side to reduce loss. In each case, there is a drawback in each case, for example, when it is likely to occur, it stays in the handling room and wastes time.

[0003]

SUMMARY OF THE INVENTION The present invention relates to a conventional threshing system which eliminates the loss caused by the difference in threshing conditions and the time required for threshing to eliminate wasteful time. It is an object of the present invention to adjust the transfer force in the handling room in response to the above-mentioned drawbacks.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a toothing implanted on a peripheral surface of a handling drum having a transfer angle with respect to a rotational direction so as to give a transfer action to threshing from a supply side to a discharge side. In addition, the transfer angle can be freely set.

[0005]

With this configuration, if the threshing of the thresh is difficult, the transfer angle of the tooth treatment is changed to a small value to reduce the transfer force to the discharge side and the residence time of the thresh in the handling room is prolonged. In order to prevent the untreated material from being discharged from the discharge side, and to facilitate the threshing process, the transfer angle is changed to a large value so that the transfer force is increased and the threshing process is not performed in the handling room. Thus, the threshing treatment action adapted to the respective conditions is performed. In addition, there is an action of pressing against the sorting screen side by the divided teeth.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. The variable toothing shown in this example is installed in the handling room of a full-feed axial flow combine. First, the outline of this combine is described. Grain stalks are scraped by a scraping reel (1) and cut. The grain stalks cut and cut by the blade (2) are lifted from the scraper auger (3) to the supply side (X) of the handling room (6) by the chain conveyor (5) of the feeder house (4) and the present invention. The threshing process is performed by the variable tooth handling (A) described later. The grains, culm pieces and fine dust generated by this threshing process are supplied to the receiving net (7).
And falls on the swinging sorting section (8), and moves toward the terminal side thereof. In the course of this movement, grains and fine culm breaks that have leaked downward from the swing sorting section (8) are blown by the blower fan (9) and the suction fan (11) attached to the end of the handling drum (10). The grains fall into the first gutter (13) and the second fall into the second gutter (14), respectively, by the sorting wind and the blowing fan (12). ) Is stored in a predetermined container, and the second product is returned to the above-mentioned swing sorting (8) through the lower cylinder (16) and is sorted again.

[0007] A large number of the variable toothing (A) are planted on a line drawn in a spiral around the handling cylinder (10).
A large number of the variable teeth (A) are linearly divided at substantially equal intervals in the axial direction from the starting end of the gripping cylinder (10) toward the discharge side (Y), and are arranged and arranged.

Therefore, if the transfer angle (α) is changed to a large value, the transfer force of the thresh is increased, and the transfer force is reduced as the transfer angle is reduced. In addition, if the transfer angle (α) on the supply side (X) is increased, uptake of the cereal stalk is improved, and even if the transfer angle (α) on the discharge side (Y) is reduced, the untreated material is discharged outside the machine. Therefore, the transfer angle (α) may be changed on the supply side (X) and the discharge side (Y) of the handling cylinder (10).

[0009]

According to the present invention, as described in detail above, the teeth to be implanted on the peripheral surface of the handling drum are moved at a transfer angle with respect to the rotation direction so as to give a transfer action to the threshing from the supply side to the discharge side. ,
In addition, because the transfer angle is configured to be freely changeable, if the threshing process is difficult due to threshing difficulties due to differences in the type of threshing and creatures or degree of drying, the transfer angle of the variable tooth handling is reduced. By changing the transfer force and lengthening the residence time in the handling room so that complete processing can be performed so that unprocessed materials are not discharged outside the machine and no loss occurs, If it becomes easy, change the transfer angle to a large value to increase the transfer force, eliminate waste of time in handling the threshing material and holding it in the room, and improve the threshing process performance adapted to each condition. You can do it. In addition, threshing is improved by pressing against the receiving net side by the tooth handling, and dust is sucked by a suction fan attached to the end of the handling cylinder.
