Description

[Detailed description of the invention] The present invention provides a spiral flow sorting chamber on the lateral side of the handling chamber when viewed in the direction of the rotational axis of the handling cylinder, and the material to be processed from the handling chamber is transferred from the handling chamber side. A wind sorting chamber configured to carry out sorting by sorting air sent toward the spiral flow sorting chamber in a direction substantially perpendicular to the rotation axis of the handling drum extends from below the handling chamber to below the spiral flow sorting chamber. By providing a spiral flow sorting chamber, the processed material from the handling chamber and the dust air from the wind sorting chamber are made to flow in a spiral around an axis substantially parallel to the rotational axis of the handling barrel. The present invention relates to a threshing and sorting device configured to collect grains from the spiral flow sorting chamber to a wind sorting chamber and to discharge waste dust to the outside of the machine.

In the above-mentioned threshing sorting device, if the material to be processed from the handling chamber is configured to join the flow of the spiral flow sorting chamber 2 with the rotational inertia given in the handling chamber, the flow direction of the spiral flow sorting chamber and the exhaust from the wind sorting chamber can be adjusted. The direction of the dust wind will be opposite.

Therefore, in the conventional device, as shown in FIG. 4, part of the dust air from the wind selection chamber 1 flows into the spiral flow sorting chamber 2 while facing the spiral flow. and
Disturbance occurs in the spiral flow, and the sorting performance in the spiral flow sorting chamber 2 deteriorates, and more dust is returned to the wind sorting chamber 1, and grains mixed in the dust air from the wind sorting chamber 1 are not sorted. The problem of dust being directly discharged outside the machine along with the exhaust wind was likely to occur.

As mentioned above, the present invention prevents the disturbance of the spiral flow caused by the dust exhaust air from the wind sorting chamber and the direct discharge of grains, and furthermore, the spiral flow sorting room It is possible to adjust the amount of inflowing dust exhaust air and maintain the sorting performance in the spiral flow sorting chamber in good condition.
The purpose is to perform sorting efficiently as a whole and to prevent loss of grains.

Next, an embodiment of the threshing sorting device of the present invention will be described based on the drawings.

The threshing husk culms supplied to the handling chamber 4 by the threshing holding and conveying device 3 are handled and threshed by the rotating handling drum 5, and the threshed waste straw is discharged from the handling chamber 4 by the conveying device 3.

When viewed in the direction of the rotation axis of the handling cylinder 5, the spiral flow sorting chamber 2 is provided on the lateral side of the handling chamber 4, and the residual processing material in the handling chamber 4 is moved to the end of the handling chamber by the inertia imparted by the handling cylinder 5. The liquid is supplied to the spiral flow sorting chamber 2 through the communication port 6 of the section.

Furthermore, there is a sorting plate 7 for sorting the threshed material while being oscillatedly conveyed from the handling chamber 4 side to the spiral flow sorting chamber 2 side, and a handling drum rotation shaft for moving the threshing material from the handling chamber 4 side toward the spiral flow sorting chamber 2. The wind selection room 1 is equipped with a winnowing machine 8 that sends the wind in a direction almost perpendicular to the core.
It is provided extending from the lower part of the handling chamber 4 to the lower part of the spiral flow sorting chamber 2, and a communication port between the spiral flow sorting chamber 2 and the wind selection chamber 1 is provided in the direction of the rotation axis of the handling drum of the wind selection chamber 1. The shape is strong throughout the entire flesh.

Thus, the threshing material that is dropped and supplied to the wind sorting chamber 1 through the handling chamber 4 or the clip net 9 is sorted by the oscillating wind, and at the same time, the waste air is made to flow into the spiral flow sorting chamber 2.

Then, the material to be processed from the handling chamber 4 supplied to the spiral flow sorting chamber 2 and the dust exhaust air from the wind sorting chamber 1 are moved around an axis approximately parallel to the rotation axis of the handling barrel by the suction force of the blower 10. The grains are separated into grains and dust by spiral flow in the spiral flow sorting chamber 2, and the grains are collected from the spiral flow sorting chamber 2 to the wind sorting chamber 1. It is designed to be discharged outside the machine from 12.

A screw conveyor 13 for carrying out the first processed material from the lower part of the wind selection chamber 1 to the outside of the machine, and a wind selection room 1
A screw conveyor 14 is provided to return the second processed material and the collected material from the spiral flow sorting chamber 2 to the handling chamber 4, and as the threshed husk culms are threshed and the threshed grains are sorted, the first processed material is returned to the outside of the machine. This allows the second item to be taken out and re-handled.

A curved guide surface 15 is formed on the terminal side wall 15 of the wind selection chamber 1 to reverse the dust exhaust air from the wind selection chamber 1 in a direction substantially along the flow direction in the spiral flow sorting chamber 2. A partition wall 1 extends downward from the spiral flow sorting chamber 2 side at the end of the chamber 1.
7 is provided, and a space is formed between it and the terminal side wall 15 for the reversal and rotation of the dust exhaust air by the curved guide surface 16, so that the dust exhaust air from the wind selection chamber 1 flows into the spiral flow sorting chamber. Care has been taken to ensure that the dust flow merges with the spiral flow of No. 2 without disturbing it, and to prevent the dust exhaust air from flowing directly into the dust exhaust port 11 without spirally turning.

A curved guide surface 1 is provided on the inversion turning space side of the partition wall 17.
A distributor 18 having a triangular shape when viewed from the side is installed to be able to freely slide up and down, and distributes the dust exhaust air from the 6 side into the spiral flow sorting chamber 2 and the wind sorting chamber 1. A rotary shaft 19 for sliding and slidingly fixing the distribution tool 18 is made to protrude outside the machine, and a rotary shaft operating tool 20 is attached to the protruding end of the rotary shaft 19.
The distribution tool 18 is adjusted in position according to the amount of processed material mixed into the dust exhaust air from the wind sorting chamber 1, and the part of the dust air flowing into the spiral flow sorting chamber 2 is adjusted. By changing and adjusting the amount, it is possible to cause a large amount of processed material to join the spiral flow and stall it, or to prevent the amount of processed material flowing into the spiral flow sorting chamber 2 from being too small to fully utilize its sorting function. This is to allow sorting processing to be performed while preventing trouble from occurring.

In summary, the present invention provides a threshing sorting apparatus officially registered, in which the dust exhaust air from the wind sorting chamber 1 is directed to the terminal side wall 15 of the wind sorting chamber 1 in the direction of flow in the spiral flow sorting chamber 2. In order to form a curved guide surface 16 for reversing in the direction along which the wind passes, and to form a space for reversing and turning by the curved guide surface 16, a downward direction from the spiral flow sorting chamber 2 side is provided at the end of the wind selection chamber 1. A side surface is provided on the side of the inversion turning space of the partition wall 17 to adjust the amount of dust flowing into the spiral flow sorting chamber 2 out of the dust exhaust air from the curved guide surface 16 side. It is characterized in that the dispensing tool 18, which is triangular in appearance, is attached so that its position can be adjusted up and down.

That is, since the dust exhaust air from the wind sorting chamber 1 is allowed to join the spiral flow in the spiral flow sorting chamber 2 without disturbing it, it is possible to prevent the deterioration of the sorting performance in the spiral flow sorting chamber 2 caused by the disturbance of the spiral flow. Moreover, by reversing the dust exhaust air from the wind sorting chamber 1 along the curved guide surface 16, grains mixed therein can be sorted out.
By adjusting the volume of dust exhaust air flowing into the spiral flow sorting chamber 2 according to the amount of the waste mixed in the dust exhaust air, a large amount of the waste flows into the spiral flow, stalling it, and improving the sorting performance. This allows for efficient sorting without reducing the quality of the grains or causing a situation where the sorting function cannot be fully utilized due to the supply amount being too small. I can now do it better.

Furthermore, as described above, by reversing the flow direction of the dust exhaust air from the wind selection chamber 1 into a spiral flow and merging it, the grain temperature mixed in the dust exhaust air is directly discharged to the outside of the machine together with the dust exhaust air. This also prevented grain loss.
