Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sorting device for a threshing machine, and the present invention relates to a sorting device for a threshing machine, and it is possible to obtain a good sorting action state suitable for the conditions and properties of the processed material (cereals) from the handling barrel, such as rice, wheat, etc. The purpose is to make a thorough selection.

For this reason, the following technical measures were taken.

That is, a swinging sorting device is provided with a swinging sorting plate 2 which receives grains, straw waste, etc. from a handling cylinder 1 and sorts them while swinging and transporting them, and is configured to be rotatable up and down, so that the mesh can be adjusted. 3, and an air blowing device 5 configured such that the strength of the sorting air generated by the sorting fan 4 can be adjusted freely.
The oscillating sorting plate 2 and the blower device 5 are provided with:
Due to the adjustment operation of the sorting plate 2 in the direction of decreasing the mesh size, the interlocking mechanism 6 is activated so that the sorting air of the sorting fan 4 becomes stronger.
A sorting device for a threshing machine is configured in an interlocking manner through the following.

In the illustrated example, the threshed grain A is composed of a handling barrel 1 rotatably mounted on a shaft in a handling chamber 7, a receiving net 8, and a swing sorting device 3 located below this and swingably provided. ing.

The oscillating sorting device 3 moves a large number of oscillating sorting plates 2 onto a shaft 9.
It is constructed so that it can be freely rotated up and down around the center, and the mesh size can be adjusted to be large or small.

This alignment adjustment configuration includes a frame 10 that pivotally connects the lower ends of the respective sorting plates 2, the upper ends of which are pivotally supported on the frame 10, and the lower ends of which are connected to the operating wire 1.
The arm 12 connected to the arm 1 is supported by a shaft 13 so that the intermediate portion thereof can rotate freely.

A spring 14 always urges the lower end of the arm 12 in the direction of arrow A.

The blowing device 5 is composed of a sorting fan 4, a cam splitting pulley 15 and a driving pulley 16 provided on the shaft 15 of the fan 4, and a belt 17 wound and tensioned between the two.

The actuation arm 18 is pivotally supported by a shaft 18a,
Rod 1 that operates the cam part of the cam split pulley 15
9 are connected to each other, and a tension roller 20 is provided.

The operating lever 21 has a lower end portion of a rod 22 pivotally supported at its lower portion connected to the operating arm 18, and has a pin 23 protruding from the lever 21.

A connecting arm 24 has a long hole 25 into which the pin 23 of the lever 21 is inserted, and its end is connected to the operating wire 11.

Therefore, if the operating lever 21 is operated from the solid line position in FIG.
2 is pulled upward and the actuating arm 18
The rod 19 is rotated about 8a in order to be pulled in the direction of arrow C. Then, the cam portion of the cam splitting pulley 15 is broken, and the pulley 15 widens the belt groove width to become smaller in diameter, causing the sorting fan 4 to rotate at high speed together with the shaft 15, thereby increasing the sorting air.

On the other hand, when the operating lever 21 is operated in the direction of the arrow B, the connecting arm 24 is pulled by the pin 21, thereby pulling the operating wire 11 in the direction of the arrow D. Then,
Since the arm 12 moves the frame 10 in the direction of the arrow H around the shaft 13 while resisting the spring 14, the swing sorting plate 2 rotates downward around the shaft 19 to reduce the mesh size to zero.

Furthermore, when the operating lever 21 is operated from the solid line position in FIG.
4 does not move, so the mesh size of the swinging sorting plate 2 remains large. On the other hand, when the rod 22 is pushed downward and the actuating arm 18 rotates to pull the rod 19 in the direction of arrow C, the cam split pulley 15
The pulley 15 narrows the belt groove width and becomes larger in diameter, and the sorting fan 4 rotates at a low speed together with the shaft 15, weakening the sorting air contrary to the above.

26 indicates the first spiral, and 27 indicates the second spiral.

In the configuration of the above example, first of all, when working with rice, since there is little generation of straw waste, the operation lever 21 is set to position B in FIG. Keep the eyes relatively large. When the work starts, the material to be processed from the handling cylinder 1 falls onto the swinging sorting plate 2, where it is sorted into grains (No. 1) and straw waste, and subjected to wind separation by the sorting fan 4. Grains are spiral 1 and 2 depending on
6 and are discharged outside the machine, and the waste, stalked grains, etc. fall to the second spiral and are sent to the handling cylinder again to be reprocessed.

In addition, when the rice is slightly damp, please press the control lever 2.
1 to position A in Fig. 2, the oscillating sorting plate 2
While the alignment remains the same, the actuating arm 18 pulls the rod 19 in the direction of the arrow C via the rod 22 and rotates to enlarge the belt groove width of the split pulley 15 to make it smaller in diameter. Only the wind is strengthened to improve the wind selection effect.

In addition, when working with wheat, a large amount of straw waste is generated, so move the operating lever 21 in the direction of arrow B (Fig. 2C).
position) to reduce the mesh size of the oscillating sorting plate 2 to 0 to reduce the leakage rate so that the straw waste does not fall into the first spiral as much as possible. At the same time, the sorting wind of the sorting fan 4 is strengthened via the rod 22, the actuating arm 18, and the rod 19, and the effect of sorting and removing straw waste (air selection effect) can be improved.

Since this invention has taken the technical measures as described above, when the amount of straw waste generated from wheat etc. is large, the oscillating sorting plate 2
As the mesh size is adjusted to small or zero, the sorting wind by the sorting fan 4 also becomes stronger, so that the straw waste is collected as much as possible during the sorting operation on the oscillating sorting plate 2.
No. 1 item (screw) to prevent it from falling on the spiral
The oscillating sorting plate 2 prevents straw waste from entering the inside.
Since a large amount of straw debris falling from the terminal end can be removed from the machine using a strong sorting wind, the sorting effect can be improved.
