The technology disclosed in Japanese Utility Model Publication No. 59-193241 is disclosed.
However, the oscillation frequency (frequency) is set to be constant regardless of the amount of the leaked material.

[0003]

In a threshing and sorting apparatus having a swinging and sorting shelf that receives a threshing-treated product and swings and conveys it while swinging and sorting it, a threshing and sorting device for threshing in a threshing chamber is provided. The amount of threshed material generated in the threshing chamber changes depending on conditions such as the pattern of the product and the degree of dryness and humidity, and generally, the selection leakage degree of the rocking sorting shelf is adjusted as in the former conventional technique described above. However, for example, even if the leakage rate is increased to promote the leakage of the grain, the amount of dust transferred does not change and the dust discharged from the threshing chamber is discharged. Since the amount of substances increases, the sieving and screening action becomes insufficient. So this
In order to send out increasing dust quickly, the latter conventional
It is also possible to change the vibration width of the rocking sorting shelf as in the technology.
However, the feed rate changes only by changing the amplitude.
There is almost no change in the separation effect of the separation of straw waste,
A problem that grain loss (third loss) is likely to occur due to poor sorting on the dynamic sorting shelf or taking it out of the machine due to poor handling.
There was a problem.

An object of the present invention is to solve such a problem, and an object of the present invention is to maintain an appropriate selection state according to the amount of threshing products from the threshing chamber.

[0005]

Means for Solving the Problems The technical means according to the present invention includes an oscillating sorting shelf 2 for leaching and sorting grains while receiving and transporting the processed substances that have leaked from the threshing chamber 1 and oscillating. A swinging sorting device 13 and a leaking mesh adjusting means for changing and adjusting the leaking mesh so that the larger the amount of the leaked waste from the threshing chamber is, the larger the screening leakage mesh 3 of the sorting shelf 2 is. A swing number adjusting means for changing and adjusting the swing number so that the swing number of the swing sorting device increases as the amount of the leak treated substance increases , and the amount of leak treated from the threshing chamber increases. It is characterized in that the wind force adjusting means for changing and adjusting the wind force for sorting is strongly linked with the wind force adjusting means so that the wind for sorting by 29 becomes strong.

[0006]

Effect of the Invention The processed products threshed in the threshing chamber 1 are leaked and discharged from the threshing chamber 1 onto the rocking sorting shelf 2 and are rocked and transferred, but the grain leak sorting is performed. , This threshed processed product varies depending on the work conditions such as the pattern of the processed product to be threshed, the wet handling of morning dew or raining, etc. When a large amount of threshing-treated products are generated, and thus the leakage of grain is promoted by enlarging the sorting leakage factor 3 of the swing sorting shelf 2, the swing number of this swing sorting shelf 2 is increased. There was good loosening and transporting the clean room was brought to atmospheric the oscillating number so as to be larger,
On the contrary, when there are few threshed products, and when the leakage of the grain is reduced by decreasing the sorting leakage ratio 3 of the swing sorting shelf 2, the swinging of the swing sorting shelf 2 is performed. The interlocking mechanism 4 interlocks with the relationship in which the number is small, and the selection leakage gap 3 of the rocking sorting shelf 2 and the rocking sorting shelf 2 suitable for the working conditions.
It is possible to adjust the relationship with the number of swings, and it is possible to increase adaptability to changes in conditions and improve work efficiency.

Moreover, since the larger the amount of the material to be leaked from the threshing chamber is, the stronger the sorting wind by the Kara Tsubo is controlled, it is necessary to control each of them in combination with the adjustment of the sorting leakage ratio and the fluctuation number. Since it can be done properly, it is possible to more surely avoid the occurrence of loss No. 3.

When the tilting operation is performed to the side, the selection leakage mesh 3 is made small, the number of swings of the swing sorting device 13 is reduced, and the number of rotations of the Karako 29 is reduced.

Incidentally, the selection leakage rate 3, the increase / decrease in the number of swings of the swing sorting device 13 and the adjustment of the rotation speed of the Karin 29 are detected, for example, by a sensor to detect the amount of grains leaking from the threshing chamber 1. , And the moisture detection result shows that when the amount of grains and the amount of moisture are large, the size of the leakage screen 3 is increased, the number of swings of the swing sorting device 13 is increased, and the number of rotations of the Karako 29 is increased. On the contrary, when the amount of grains and the amount of water are small, the leaking mesh size 3 may be reduced, and the number of swings may be reduced and the number of rotations of the Karako 29 may be automatically adjusted to be low.

In the threshing / sorting device constructed as described above, the sorting leakage ratio 3 of the swinging sorting shelf 2 and the swinging sorting device 13 with respect to the sorting processing amount of grains and the like threshed in the threshing chamber 1 are controlled.
The relationship between the number of swings and the wind force of the Kara 29 is set to an almost optimal state by the interlocking mechanism 4, and the grain chains are supplied to the threshing chamber 1 by the feed chain 6, and the supplied grain culms are the threshed grains. Grains and the like that have been threshed by the rotation of the handling cylinder 7 while being transferred in the chamber 1 are leaked from the threshing net 11 and are shaken and transported by the rocking and sorting device 13 below the rocking and transporting rack 14 and the rocking and sorting rack. Grains and part of straw debris and the like drop onto the grain guide shelf 18 below the rack plate of the swing sorting shelf 15 and drop onto the grain guiding shelf 18. In addition, straw debris containing a part of grain that does not leak from the threshing net 11 is transferred through the threshing chamber 1 and falls onto the straw debris sorting shelf 16 below the discharge port 12, and the swing sorting shelf 15 The grains that have not dropped further are merged with the shavings and the like to be transferred and sorted by the rocking action, and the sorted grains are below the screening leakage joint 3 between the rack plates 25 of the rocking sorting shelf 2. Fall to. Straws and the like that do not fall are conveyed toward the end on the rocking sorting shelf 2 and sent to the straw rack 17 and the sorted and sorted straws are discharged to the outside of the machine. Further, the swing transfer rack 14, the swing sorting rack 15, the straw waste sorting rack 16, the swing sorting rack 2, and the straw rack 17, which are formed in a substantially flat shape, include a dust exhaust cross-flow fan 3.
4, light straw dust, dust, etc. are sucked and discharged to the outside of the machine.

Grains that are sorted by the straw rack 17 and fall are introduced into the second trough 32 as the second grain. Also, the grains that have fallen on the grain guide shelf 18 slide down to the leading end and are taken over on the sorting net 20, where the Kara 29
The grain is sorted by being dusty with the sorting wind from, and the sorted grain flows into the first lower trough 21 and is carried out of the machine. Grains that do not fall from the sorting net 20 fall into the second trough 32 from the tip of the sorting net 20, and the threshing chamber 1 by the second reduction thrower 33 together with the second grain falling from the straw rack 17. Threshing work is performed while being returned to the inside and being reprocessed. Further, the threshed waste is discharged to the outside of the machine while being cut by the straw cutter device 9.

In this threshing work, depending on the pattern of threshing to be threshed and the working conditions such as wet handling of morning dew and raining, the threshing of grains and straw scraps threshed in the threshing chamber 1 When the generated amount fluctuates and, for example, there is a lot of grain removal, the operation lever 45 is tilted to the front side, and the sorting leakage of the swinging sorting shelf 2 through the wires 46, 47, and 48 occurs. The mesh 3 is increased to improve the leakage of the grain, and the number of swings of the swing sorting device 13 is increased (the transport force is increased) to improve the sorting and transport of dust such as straw waste, And Kara 29
The number of rotations is increased to strengthen the sorting wind and prevent the inclusion of straw waste into the first product. On the other hand, when there is little grain loss, the operation lever 45 is tilted rearward to reduce the size of the grain leakage 3 of the rocking sorting shelf 2 to reduce grain leakage.
It is possible to adjust the sorting state suitable for the threshing work condition by reducing the swinging number of the swinging sorting device 13 and lowering the rotation number of the Karato 29, which may be caused by the stagnation of dust or the taking out of the grain. The loss can be eliminated and the adaptability to changing conditions can be expanded.
