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 handle teeth, which gives a transfer action from the supply side to the discharge side to the grain removal in the handling chamber, so that the retention time in the handling chamber can be made longer or shorter depending on the conditions of grain removal. The aim is to improve the threshing treatment performance.

[0002]

2. Description of the Related Art As described above, a threshing tooth for threshing while imparting a transfer action from a supply side to a discharge side to threshing grains in a handling chamber is firmly planted on the circumferential surface of a slinging barrel to prevent threshing grains. The transfer force was unchanged. Therefore, the threshing process is affected by the threshing difficulty due to the difference in thresher varieties and the biological area depends on the threshing conditions such as the degree of dryness.When the threshing process is difficult, unprocessed substances are discharged from the discharge side to reduce the loss. In the case where it easily occurs, it has a drawback in each case such that it is wastefully stored in the handling room and wastes time.

[0003]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention According to the present invention, conditions for removing grain are eliminated in order to eliminate loss or time waste, which is caused by the difference in conditions for removing grain in the conventional ones. Therefore, the transfer force in the handling chamber is adjusted according to the above, and thus the above-mentioned drawback is solved.

[0004]

SUMMARY OF THE INVENTION Therefore, according to the present invention, the handling tooth to be planted on the circumferential surface of the handling barrel is moved in a rotation angle with respect to the rotation direction so as to give a transfer action to the grain removal from the supply side to the discharge side. In addition, the transfer angle can be freely set.

[0005]

With this configuration, when it becomes difficult to perform the grain removal process, the transfer angle of the handling tooth is changed to a small value to reduce the transfer force to the discharge side, thereby reducing the retention time of the grain removal in the handling chamber. To prevent the unprocessed material from being discharged from the discharge side by making it long, and when the threshing process is easy, change the transfer angle to a large value to increase the transfer force and prevent people from threshing in the handling room. In this way, the threshing treatment action adapted to each condition is performed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments shown in the drawings will be described below. The variable handle tooth shown in this example is installed in the handle chamber of a full-supply type axial combine, and the outline of this combine is first described. The grain rod is scraped by the scraping reel (1) and cut. The grain rod reaped by the blade (2) is lifted from the scraping auger (3) to the supply side (X) of the handling room (6) by the chain conveyor (5) of the feeder house (4). The threshing process is performed by the variable handle tooth (A) described later. Grains, grain rods and fine dust generated by this threshing treatment are nets (7)
And falls on the swinging sorting section (8), and moves toward the terminal side thereof. In the process of this movement, the grains and fine rods leaked downward from the rocking sorting section (8) are the blower fan (9) and the suction fan (11) that can be attached to the end of the handling cylinder (10). Grain drops into the first gutter (13) and second one into the second gutter (14) by the sorting wind and blower fan (12). ), It is stored in a predetermined container, and the second product is returned to the swing selection section (8) through the thrower tube (16) and re-sorted.

[0007] A large number of the variable toothing (A) are planted on a line drawn in a spiral around the handling cylinder (10).
The variable handle teeth (A) are linearly arranged in the axial direction from the starting end of the handle cylinder (8) toward the discharge side (Y), and are arranged in the circumferential direction at equal intervals and are planted in large numbers.

Therefore, when the transfer angle (α) is changed to a large value, the transfer force for grain removal is increased, and the smaller the transfer angle is, the smaller the transfer force is. Also, the transfer angle (α) on the supply side (x)
If the value is increased, the intake of the grain rod is improved, and even if the transfer angle (α) on the discharge side (Y) is reduced, the unprocessed material (x) and the discharge side (Y) can be prevented from being discharged outside the machine. Transfer angles (α) on the supply side (x) and discharge side (Y) of the handling cylinder (10)
May be changed.

[0009]

As described above in detail, according to the present invention, the handling teeth to be planted on the circumferential surface of the handling barrel are moved at a transfer angle with respect to the rotation direction in order to exert a transfer action on the grain removal from the supply side to the discharge side. Have a
In addition, since this transfer angle is configured to be freely changeable, if the threshing process is difficult due to the difference in the type of threshing and the threshing conditions such as the organism or the degree of dryness make the variable handling tooth transfer angle small. Change the transfer force to a small value to lengthen the retention time in the handling room so that complete processing can be performed so that unprocessed materials are not discharged outside the machine and loss occurs, and threshing processing is also performed. If it becomes easy, the transfer angle is changed to a large value to increase the transfer force and eliminate the waste of time that wastes the grain in the handling room and improves the threshing treatment performance adapted to each condition. It came to be able to measure.
