Description

[Detailed explanation of the invention] (a) Industrial application field The present invention is designed to rationally suck and discharge materials that have been sieved by a swinging sorter mounted below the handling chamber and sent to the terminal side. The present invention relates to a threshing sorting device that completely eliminates the third loss from the suction and dust removal fan.

(b) Conventional technology As a conventional technology, materials to be handled from the handling room are sorted by a swinging sorter mounted below the handling room, and suction and exhaust of the same size are installed on both ends of the swinging sorter. A structure in which dust fans are provided facing each other to suction and discharge dust such as straw waste that has been sieved by a swinging sorter and sent to the terminal end from both sides is, for example, developed in Utility Model Opening in 1973-
This is disclosed in Publication No. 137266.

However, in the above configuration shown in the same publication, the suction ports of the opposing suction and dust removal fans are configured to have the same height, so grains are removed from the machine by the suction and dust removal fans. This has the disadvantage that it is sucked out and the number 3 loss increases.

(c) Problems to be solved by the invention The present invention is different from the conventional one in that it suctions and discharges only the dust such as straw that has been sieved by the oscillating sorter and sent to the terminal side from both sides. In view of the fact that even grains are sucked in where they should be, causing loss, this threshing sorter eliminates this drawback and fully demonstrates its great sorting ability, especially for multi-row combine harvesters. The aim is to provide the equipment.

(d) Means for solving the problems Therefore, the present invention is constructed as follows in order to provide a threshing sorting device as described above.

That is, if two suction dust exhaust fans are installed facing each other with suction ports opening on both sides of the terminal side of the swinging sorter mounted below the handling room, the swinging The suction port of the suction dust exhaust fan located on the thicker side of the layer of handled materials unevenly distributed on the sorting body is installed at a higher level than the suction port of the suction dust exhaust fan located on the thinner side of the layer of handled materials. It is something that

(e) Effect When configured as described in the previous section (d), the material to be handled from the handling room is sent to the terminal side while being sieved by the oscillating sorter, and dust such as straw is sucked out from both sides. Dust fans are used to suck and discharge the dust, but in this case, the height of the suction port of the suction fan is different, and the height of the suction port on the thicker side of the oscillating sorter is the same as that of the layer of the material. The grains are not sucked and discharged from the thicker side of the layer, which is higher than the height of the suction port on the thin side, and the sieving action of the grains by the rocking sorter is likely to be sustained to the terminal side. On the thinner side of the layer, where the sieving action ends quickly, dust is sucked in more vigorously through the lower suction port and is discharged to the outside of the machine.

(f) Examples The present invention will be specifically explained below based on the drawings of examples. The threshing sorting device shown in this example figure is used for a combine harvester, and in each figure, the left side is the front side in the direction of travel, and the harvested grain culm is handed over to the feed chain 1 for threshing.

Reference numeral 2 denotes a handling chamber that houses a handling cylinder, and the handling cylinder rotates in the A direction and is configured in a so-called lower handling type. A is a swinging sorter which swings back and forth below the handling chamber 2 and receives and separates the materials to be handled from the handling chamber 2 and the leaked materials from the processing barrel chamber 9, which will be described later. A feed pan 3, a chaff sheave 4, and a stroke rack 5 are installed in sequence from the rear end to the rear end, and a grain sheave 6 is provided below the chaf sheave 4. Furthermore, a sorting fin 7 is installed from below the stroke rack 5 to the end. are constructed so that they swing together as one.

Reference numeral 8 denotes a pressure fan installed below the starting end side of the oscillating sorting body a. The processing barrel chamber 9 is disposed horizontally on the terminal side of the swinging sorting body a, that is, above the sorting fins 7, perpendicular to the back and forth swinging direction, so as to receive the material sent out from above the stroke rack 5. It has a built-in processing cylinder 10 that rotates in the direction.

An arc-shaped concave 11 is installed in the lower part forming the processing barrel chamber 9, and this installation is carried out by a guide plate 12 and a support plate 13 installed horizontally on both sides.
It supports the front and rear parts of the aircraft and can be inserted and removed from one side of the fuselage. Further, the upper part is formed of a cover plate 14, and the upper end of this cover plate 14 is a bottom plate 1 which serves as a passage for the culm to be transported rearward from the handling chamber 2.
Connected to 5.

Reference numerals 16 and 17 are suction and dust removal fans equipped with large and small suction cylinders with different suction air volumes, and both of them are used to suck dust to the upper side of the stroke rack 5 forming the terminal side of the swinging sorting body a on the front side of the processing cylinder chamber 9. The dust exhaust pipes 22 and 23 are respectively attached to both side walls 20 and 21 so that the openings 18 and 19 are open to face each other, and the dust exhaust pipes 22 and 23 extend rearward and downward.

The heights h and H of the suction ports 18 and 19 facing each other with respect to the stroke rack 5 are
The height H of the suction port 9 is made higher than the height h of the suction port 18 on the left side.

Reference numeral 24 is a lead plate which is disposed obliquely with its front side biased to the left side, and is vertically disposed from the cover plate 14 to the lower surface of the bottom plate 15, and is provided at equal intervals in the horizontal direction in the upper part of the processing barrel chamber 9. The rotation of 10 in the direction B serves to send the contents in the processing barrel chamber 9 to the left side.

In addition, 25 is the 1st material removal gutter, 26 is the 2nd material ejecting gutter, 2
7 is a thrower, and 28 is a processing chamber arranged in parallel with the processing chamber 2.

Therefore, the material to be handled from the handling room 2 is sieved by the back-and-forth swinging of the swinging sorter a and the sorting air of the pressure fan 8, and dust such as straw is removed by the suction and dust removal fans 16 on both sides. , 17, unprocessed materials such as ear cuts and grains with stems are fed into the processing barrel chamber 9 from the end of the stroke rack 5 via the guide plate 12, and are transferred to the processing barrel 10 rotating in the direction B and the reed. It is processed while being sent to the left by the plate 24.

The dust generated by this processing action is sucked and discharged by the suction dust exhausting fans 16 and 17, and the leakage from the concave 11 is removed by the swinging of the sorting fin 7, which removes culms and stems from their terminal ends. It is ejected outside the aircraft. Further, the grains in the first material take-out gutter 25 are stored in a predetermined container, and the grains flowing into the second material gutter 26 are transferred to the processing chamber by a thrower 27.
After being hoisted up in 1988, it will be reprocessed.

In this way, the materials to be handled from the handling room 2 are sorted, but since the handling cylinder is rotating in the direction A, the materials to be handled from the handling room 2 are sorted on the right side of the swinging sorter a. The layer is unevenly distributed on the left side and becomes considerably thicker than on the left side, and there is a difference in thickness between the right and left side layers of the material to be handled.In this state, it is sent to the terminal side while being subjected to the sieving effect due to rocking. Therefore, this swinging motion continues until the end on the right side, and ends earlier on the left side. At this time, the suction port 19 of the suction dust exhaust fan 17 on the right side is configured to have a high height H with respect to the stroke rack 5, making it difficult for grains to be suctioned and discharged. It makes it easier.

Next, FIG. 3 shows another embodiment in which, as mentioned above, the suction port 19 of the right suction dust exhaust fan 17 is at a height H with respect to the stroke rack 5, and the left suction dust exhaust fan 16 is The height h of the suction port 18 is higher than the height h of the suction port 18, and the distance M between the processing cylinder 10 and the axis is larger than the distance m shown in FIG. It is composed of

In this way, the suction port 19 moves away from the processing barrel chamber 9, and the grains that are processed in the processing barrel chamber 9 and are released toward the front by the processing barrel 10 rotating in the direction A are sucked and discharged from the suction port 19. In addition, the suction port 19 approaches the passage side of the culm being transported rearward from the handling room 2, and more actively sucks the dust blown up by the pressure fan 8, thereby increasing the suction of the culm. This will prevent air from blowing up into the aisle.

(g) Effects of the invention As detailed above, this invention has suction ports opened on both upper sides of the terminal end of the swinging sorter mounted below the handling room, and two suction dust exhaust fans facing each other. Of the two suction and dust removal fans, the suction port of the dust removal fan, which is located on the thicker side of the layer of unprocessed materials unevenly distributed on the oscillating sorter, is positioned on the side with the thinner layer of unprocessed materials. Since it is installed at a higher level than the suction port of the suction and dust removal fan, the sieving action on the thicker side of the layer of materials unevenly distributed on the oscillating sorter is likely to be sustained to the end, and conversely, The sieving action on the thin side ends quickly, but since the suction port on the thick side of the layer is high, it is difficult for grains to be sucked out from the suction port.
In addition, the suction port on the thinner side of the layer is located at a lower position to actively suck and discharge dust.
This allows you to completely eliminate loss of time.

In particular, the configuration according to the present invention is suitable for multi-row combine harvesters and is rational as a threshing sorting device equipped with an oscillating sorting body with a large sorting width, and the sorting ability can be fully demonstrated.
