Description

[Detailed explanation of the invention] If the sorting device of the threshing machine is a rocking sorter, if the processing conditions are good, such as when the culm is relatively dry or it is easy to thresh, it is possible to thresh with high efficiency. A large amount of waste material is supplied to the animal sorter, and as a result of the shaking action, the grains form a thick layer at the bottom, so cut straw is the least likely to be mixed into the grains. , and in order to leak a large amount of grain, a wide first leakage sorter is required.

However, when harvesting and threshing wet or fallen shell culms, the efficiency of threshing has to be reduced. easily mixed into
It was difficult to separate and remove the cut straw by only sorting the original plate using the first original plate.

The present invention is capable of preventing the mixing of cut straw into the first grain regardless of the dryness or wetness of the culm or other conditions, and it is possible to prevent the mixing of cut straw into the first grain, but it is possible to prevent the mixing of cut straw into the first grain, and to prevent the cutting straw from entering the first grain. It is possible to always accurately blow away straw waste in the gap between the upper part and the material to be sorted on the first leakage sorter to be accurately transferred onto the second leakage sorter. The present invention aims to provide a sorting device for a thresher that can switch the sorting state between high-efficiency threshing and low-efficiency threshing with a simple operation. In the air passage, there is a sorting board that receives and transfers the material to be handled, a first leakage sorter connected to the end of the transfer facing the first receiving gutter, and a part from below the first leakage sorter. In a threshing machine comprising a swinging sorting body having a first original plate facing at the tip thereof across a wind screening gap, an opening/closing plate pivoted so as to come into contact with and away from the first leakage sorting body; , the second original plate is pivotally connected to the upper end of the first original plate so that it can freely rise and fall, and when the opening/closing plate leaves the leakage sorting body furthest, the second original plate stands up, and the opening/closing plate comes into contact with the leakage sorting body furthest. Then, the second original plate is interlocked and connected so as to lie down on the second leakage sorting body on the lower side thereof.

In the following, the embodiment shown in the drawings will be described. Reference numeral 1 denotes a handling cylinder that is mounted on a shaft in a handling chamber 3 having a receiving net 2, and is disposed below the entrance side of the handling chamber 3 to remove dust from below the receiving net 2. A winnower 6 is provided to form a sorting air passage 5 in a portion spanning the sorting chamber 4, and the sorting air passage 5 includes a transfer sorting plate 7 facing the lower surface of the receiving net 2;
A first leakage sorting body 9 consisting of a net extending from the transfer end toward the top of the first receiving gutter 8, and a first leakage sorting body 9 which faces the end from below the most leakage sorting body 9 across a wind separation gap. - An original plate 10, and a chaff sieve 1 extending from the upper end of this original plate 10 toward the second receiving gutter 11a and constituting the second leakage sorting body.
1, and a chaff sieve 12a and a transfer plate 12b extending above the most leakage sorting body 9 and the chaff sieve 11.
A swinging sorting body A including a rough sorting body 12 and the like is installed so as to swing in a direction parallel to the handling cylinder axis 1a.

An opening/closing plate 13 is pivoted to the lower part of the first leakage sorting body 9 so as to be able to freely come and go. A second original plate 14 that can be converted into a laid-down position on its side on the chaff sieve 11 constituting the leakage sorting body is pivotally mounted, and an arm 15a protruding from the opening/closing plate 13 and the second original plate 14; 16b
The upper ends are rotatably connected to the front and rear ends of the connecting rod 16, and the arm 15a of the opening/closing plate 13 is pulled toward the transfer sorting plate 7 by the bomb 17, and the other arm 15b is connected to the protrusion 18. It is connected to an operating rod 20 that has two recesses 19 and 19 that engage and disengage.

In addition, 21 in the drawing is a dust exhaust port, and 22 is a foot chain 23.
The processing cylinder is pivotally supported in a processing chamber that communicates with the processing chamber 3 provided below the pinching rail 23b, and a transfer spiral 24 is connected to the lower side of the processing cylinder. It faces above the rough sorting body 12.

25 is a straw conveyor, 26 is a cutter, and 27 is a second thrower installed on the opposite side of the foot chain 23a, the discharge port of which is a second reducing passage formed between the side wall of that side and the handling chamber 3. Since it is open toward, the second material is returned onto the transfer sorting plate 7.

Next, to explain the operation, the grains and small straw waste generated by threshing by the handling drum 1 leak from the receiving net 2 onto the transfer sorting plate 7, and the oscillating sorting plate A swings. While being transported by
At the end of the filter, some of the straw pieces and grains discharged from the dust inlet 28 join thereon, and are sent out onto the leakage sorter 9.

At this time, if the threshing efficiency is high, the operating rod 20 is moved to the lower side in the transfer direction and the recess 19 on the lower side is engaged with the protrusion 18, so that the opening/closing plate 13 is separated from the bottom surface of the leakage sorting body 9 most. When the second original plate 14 is kept upright, the grains in the lower layer are transferred and fall from the entire surface of the first leakage sorting body 9 into the first catch gutter 8, and the sorting air is transferred to the first leakage sorter 8. While blowing through the body 9, light straw waste etc. are blown apart and discharged from the dust exhaust port 21.

Then, the grains attached to the cut straw and twigs that have been transferred to the end of the leakage sorting body 9 are thrown out onto the chaff sieve 11 without leaking, and in the meantime, the grains are subjected to wind selection in the wind selection gap a. The grains that have been received and made into single grains are oscillated on the second master plate 1.
While the fourth and third original plates 10 slide down toward the first receiving gutter 8, the original plates are sorted by the sorting wind, and the grains that are attached to branches and are subject to large wind pressure pass over the second original plate 14 and onto the chaff sieve 11. to move to.

The second part of the debris that fell onto the chaff sieve 11 in this way leaks from the top of the chaf sieve 11, falls into the second receiving trough 11a and is returned to the second part, and the straw waste is removed from the dust outlet 2.
1 is ejected from the machine.

Further, the long straw, ear cuts, etc. in the handling chamber 3 enter the processing chamber and are processed by the processing cylinder 22, and are also transferred by the transfer spiral 24 and fall onto the rough sorting body 12.

The stuck grains and straw waste falling from the fourth exit 29 join together and are transported to the chaff sieve 12a by the transfer plate 12b. chaff sieve 11
The waste straw leaks and falls into the second receiving gutter 11a, and the waste straw is carried out of the machine.The waste straw is supplied to the cutter 26 by the waste straw carrier 25 and cut.

Furthermore, if the threshing efficiency is low, as shown by the chain line in FIG. Since the leakage area of the lower sorting body 9 is reduced and leakage does not occur on the upper side, it is possible to prevent the layer of the material to be sorted from becoming too thin and the cut straw leaks, and the sorting wind is uniform. Since the area that blows through the leakage sorter 9 becomes smaller, the sorting wind that blows through the lower part of the leakage sorter 9 becomes stronger, and even if the material on the screen is wet, it can be screened well. Since the second original plate 14 becomes low (lower), the transition of the mesh material from the first leakage sorting body 9 to the chaff sieve 11 becomes smooth, and during that time, the straw waste is removed in the wind separation gap a, and the second material is Even if it is wet, it is guided by the lying second original plate 14 and shifts to the chaff sieve without delay.

As mentioned above, the present invention includes a sorting plate that receives and transfers the material to be handled in the sorting air path from below the receiving screen in the handling room to the dust sorting room, and a sorting plate that is connected to the end of this transfer and placed above the receiving gutter. A threshing machine comprising an oscillating sorting body, which is equipped with a first leakage sorting body facing forward, and a first original plate facing the top end of the first leakage sorting body across a wind separation gap from below. The opening/closing plate is pivoted so as to come into contact with and separating from the first leakage sorting body, and the second original plate is pivotally mounted on the upper end of the first original plate so that the opening/closing plate is the most leakage sorting body. When the opening and closing plate comes into contact with the first leakage sorter, the second original plate stands up, and when the opening/closing plate comes into contact with the first leakage sorter, the second original plate is interlocked and connected so that it falls down onto the second leakage sorter on the lower side, so that the grain is threshed. Even if the shell culm is relatively dry or easy to thresh and can be threshed with high efficiency, or even if the shell culm is covered with dew or has fallen down, it must be threshed at a low efficiency. By simply connecting the opening/closing plate and the second original plate and adjusting their rotation, during high-efficiency threshing, the front side of the first leakage sorter is used to promote the leakage of the first grains while reducing the most leakage. The material to be sorted is transferred from the sorting body to the second leakage sorting body, and while it is being screened in the wind separation gap, the receiving is stopped by the second original plate that stands up, the original plate is sorted, and the grain is about to be transferred to the second receiving gutter. In addition, during low-efficiency threshing, the material remaining on the first leakage sorting body can be collected in the second drainage channel while preventing cutting straw from getting into the first grain. When transferring to the lower sorting body, the second original plate is laid down and becomes low, so the objects to be sorted can smoothly fly over, and the objects to be sorted in flight can be efficiently screened. The skipped material to be sorted can be transferred to the second leakage sorter and sorted without being guided by the second original plate lying on the second leakage sorter and stagnate.
