If the rotating drum equipped with diffusion teeth does not have the ability to transport the processed material to the feed chain side, it will be on the opposite side of the feed chain side. The processed material that is biased from the dust feeding port and supplied to the rotating drum is fed to the swing sorting device and the dust discharging port as it is. For this reason, there has been a problem that the sorting efficiency in the oscillating sorting device is deteriorated, and there is a problem that so-called third loss is increased, in which grains are discharged from the dust outlet.

In order to solve these problems, the rotating drum is equipped with screw blades, and the rotating drum is conveyed to the feed chain side while disassembling the processed material supplied from the dust feed port of the handling chamber. It can be considered that the processed material is evenly supplied to the swing sorting device and the dust outlet.

FIG. 1 shows a threshing apparatus 1 mounted on a combine. Incidentally, in the best mode for carrying out the invention, in order to show an example of mounting the threshing apparatus 1 to combine, corresponds to the upstream side feed processing Mono搬 towards the left in FIG. 1, is more right in FIG. 1 process corresponds to a downstream side feed Mono搬, near side in FIG. 1 corresponds to the feed chain 2 side (the same applies to FIGS. 2 to 5). In the following description, the forward feed processing Mono搬 upstream side, displays a feeding process Mono搬 downstream side and rear.

  As shown in FIG. 1, the threshing apparatus 1 is provided with a handling chamber A on the upper side, a swing sorting apparatus B on the intermediate side, and a recovery apparatus C on the lower side. In the threshing device 1, a handling cylinder 3 for handling the harvested cereal while being held and conveyed by the feed chain 2 is pivoted on the handling chamber A, and the receiving net 5 for leaking the treated product. Is disposed below the barrel 3.

  The swing sorting device B includes a first grain pan 6 that catches the processed material leaked from the receiving net 5, a chaff sheave 7 and a stroll rack 8 that are sequentially positioned behind the first grain pan 6, and a lower portion of the chaff sheave 7. A second sheave pan 19 located above the chaff sheave 7 below the rear end of the handling cylinder 3 is installed on the sheave case 16. Has been.

  The recovery device C includes a tang 10 located on the lower side of the grain pan 6 and a first thing transporting screw that collects the leakage (first thing) from the grain sheave 9 below the grain sieve 9 and laterally feeds it to the horizontal side. 11, a second object transport screw 12 that collects the leaked material (second object) from the grain sheave 9, the chaff sheave 7, etc. and laterally feeds it to the horizontal side, and a first object transport screw 11 and a second object transport screw 12. A rotating fan 13 is disposed between the two and the second article conveying screw 12 to supply the sorting air.

  A rotating drum 14 is provided at the rear lower side of the handling drum 3, and the processed material supplied from the dust feed port 4 of the handling drum 3 is unwound and processed by the rotating drum 14, and the grain is taken out from the dust. . A dust exhaust fan 15 is disposed behind the rotary drum 14, and is configured to be discharged by the upper fan guide 17 and the lower fan guide 18 so as to discharge the waste from the machine. A guide member 21 to be described later is provided on the upper outer peripheral portion of the rotary drum 14, and a sieve member 22 to be described later is provided at the rear end portion of the second gren pan 19.

  As shown in FIGS. 2 to 4, the rotating drum 14 is supported on the side plate 25 of the threshing device 1 so as to be rotatable around an axis in a direction orthogonal to the front-rear direction (conveying direction). A spiral screw blade 23 is fixed to the outer peripheral portion of the rotating drum 14 so that the processed product is conveyed toward the feed chain 2 side. A plurality of protrusions are formed on the outer peripheral portion of the screw blade 23. The pieces 24 are fixed at equal intervals over the entire circumference. The reason why the plurality of projecting pieces 24 are provided on the outer peripheral portion of the screw blade 23 is to efficiently solve and process the projecting pieces 24 in addition to the screw blade 23.

  As shown in FIG. 3, a strip-shaped discharge plate 29 that is long in the left-right direction is fixed to the end of the rotating drum 14 on the feed chain 2 side, instead of the screw blade 23 described above. This is because the processed material that has been transferred to the feed chain 2 side by the screw blades 23 from the side opposite to the feed chain 2 side and has reached the end of the feed chain 2 side is moved to the swing sorting device B or the dust collection This is because it can be guided to the mouth 20 without difficulty.

  As shown in FIGS. 2 to 4, the guide member 21 is disposed on the upper outer peripheral portion of the rotary drum 14 so as to be positioned between the dust exhaust fan 15 and the rotary drum 14. The guide member 21 includes a rod 21a which is an example of a plurality of bars that are long in the left-right direction, a mounting plate 21c fixed to both ends of the rod 21a, and two left and right reinforcements fixed to an intermediate portion of the rod 21a. Intermediate plate 21b, and fixed to side plate 25 of threshing device 1 so as to be attachable / detachable and position-adjustable. The frontmost rod 21a is provided across the left and right intermediate plates 21b, and is set to be shorter than the other rods 21a. This is because the conveyance capability is most secured in the left and right central portions of the rotating drum 14.

  When the guide member 21 is configured as described above and the handling cylinder 3 is rotated, a large amount of processed products are gathered on the opposite side to the feed chain 2 side, and the opposite side to the feed chain 2 side. Accordingly, the processed material is supplied rearward from the dust feed port 4. Then, the processed material can be conveyed to the feed chain 2 side in cooperation with the guide member 21 while the processed material is unwound on the feed chain 2 side by the screw blades 23 provided on the outer peripheral portion of the rotating drum 14. . Therefore, the screw blades 23 and the guide member 21 can uniformly supply the processed material to the swing sorting device B located below the rotating drum 14 and the dust outlet 20 positioned behind the rotating drum 14. . As a result, it is considered that the sorting efficiency in the rocking sorter B can be improved, and the third loss in which the grain is discharged from the dust outlet 20 can be reduced.

  Moreover, since the clearance gap is formed between the rod 21 and the rod 21 which comprise the guide member 21, the processed material supplied from the dust feed port 4 by cooperation with the screw blade | wing 23 provided in the rotating drum 14 is received. The guide member 21 is configured not to have excessive resistance when transported to the feed chain 2 side. Therefore, it is possible to prevent the processed material from being excessively conveyed to the feed chain 2 side due to the conveyance capability becoming too high, and the processed material supplied from the dust feed port 4 is guided between the guide member 21 and the rotary drum 14. It is possible to prevent clogging.

  A plurality of sieving members 22 are attached to the upper surface of the rear end portion of the second grain pan 19 from the rear end portion of the second grain pan 19 toward the lower side of the rotary drum 14. The sieving member 22 is formed of a piano wire that is folded back in a U shape in a plan view and bent in a rearward upward direction from the rear end of the second Glen pan 19 in a side view. It is attached to the rear end portion of the grain pan 19 by an attachment member 26 so as to be attachable / detachable and front / rearly adjustable. Thus, by attaching the sieving member 22 to the second Glen pan 19 so that the attaching member 26 can be attached and detached and the position can be adjusted back and forth, the sieving member 22 can be replaced with a sieving member 22 having a different shape. Moreover, the front-rear position of the sieving member 22 with respect to the second grain pan 19 can be adjusted.

  When the sieving member 22 is configured as described above and the handling cylinder 3 is rotated, a large amount of processed materials are gathered on the opposite side to the feed chain 2 side, and the opposite side to the feed chain 2 side. Accordingly, the processed material is supplied rearward from the dust feed port 4. Then, the processed material can be conveyed to the feed chain 2 side in cooperation with the sieving member 22 while the processed material is unwound and processed on the feed chain 2 side by the screw blades 23 provided on the outer peripheral portion of the rotating drum 14. . For this reason, the screw blades 23 and the sieve member 22 can uniformly supply the processed material to the swing sorting device B located below the rotating drum 14 and the dust outlet 20 positioned behind the rotating drum 14. . As a result, it is considered that the sorting efficiency in the rocking sorter B can be improved, and the third loss in which the grain is discharged from the dust outlet 20 can be reduced.

  Since a gap is formed between the sieving member 22 formed in a U-shape and between the sieving member 22 and the sieving member 22, the dust feeding port 4 is coupled with the screw blade 23 provided on the rotating drum 14. The sieving member 22 is configured not to have excessive resistance when the supplied processed product is conveyed to the feed chain 2 side. For this reason, it is possible to prevent the processed material from being excessively conveyed to the feed chain 2 side due to an excessively high conveying capacity, and the processed material supplied from the dust feed port 4 is retained between the sieve member 22 and the rotary drum 14. It is considered that clogging can be prevented.

  Unlike the guide member 21 fixed to the side plate 25 of the threshing device 1, the sieving member 22 is fixed to the second grain pan 19 of the swing sorting device B that is driven to swing back and forth. For this reason, the sieving member 22 oscillates together with the oscillating sorting device B, so that the gap between the rotating drum 14 and the sieving member 22 changes, and it is considered that the process of unraveling the processed material is promoted.

  As described above, the sieving member 22 and the guide member 21 are considered to have an effect of assisting the conveyance of the processed material to the side of the feed chain 2 by the rotating drum 14, respectively. It is thought that the effect can be further expected by using 21 together. That is, since the sieving member 22 and the guide member 21 are attached at different positions, the sieving member 22 is described above with respect to the processed material supplied from the dust feeding port 4 toward the lower side of the rotating drum 14. On the other hand, the guide member 21 has the above-described effect on the processed material wound upward by the rotating drum 14 and the processed material supplied upward from the dust feed port 4 to the rotating drum 14. it is conceivable that.
