Provided.
[0037]
[Grain storage part]
The grain storage unit 10 includes a Glen tank 55 disposed immediately above the first handling cylinder 28 and the second handling cylinder 29 provided in the above-described threshing unit 6, and the above-described swing sorting unit in the Glen tank 55. 7 is connected to the first grain receiver 39 via a cereal conveyor 44, and a horizontal conveyor screw conveyor 56 is placed in the lower right side of the Glen tank 55 with its axis in the front-rear direction. A vertical conveying screw conveyor 57 having a lower end portion connected to the rear end portion of the horizontal conveying screw conveyor 56 is arranged at the right side position of the prime mover unit 11 with the axis line in the vertical direction, and the vertical conveying screw conveyor. A discharge auger 58 having a rear end connected in communication with the upper end of 57 is extended forward, and is rotatable and vertically rotatable around the rear end. 58a is a discharge port of the discharge auger 58.
[0038]
In this way, the first grain selected by the swing sorting unit 7 is conveyed into the grain tank 55 via the cereal conveyor 44 and can be stored in the grain tank 55. The first grain stored in 55 can be discharged from the discharge port 58a to the outside of the machine body through the horizontal carry-out screw conveyor 56 → the vertical carry-out screw conveyor 57 → the discharge auger 58.
[0039]
[Motor part]
The prime mover unit 11 has an engine E disposed on the upper rear portion of the fuselage, and the engine E is linked to each power mechanism unit such as the first cutting blade device 20 and the transmission 13 via a transmission mechanism (not shown). Yes.
[0040]
And by driving the engine E, each power mechanism part operates in conjunction.
[0041]
In the configuration as described above, the gist of the present invention is that, as shown in FIG. 3, a feed pan 61 that receives the threshed grain and swarf on the rocking body 32, and a grain supplied from the feed pan 61. A front chaff sheave 62 that roughly sorts and scraps is disposed adjacently in the front-rear direction, and the front chaff sheave 62 is disposed below the feed pan 61 so that the front chaff sheave 62 and the feed pan 61 A head space S1 is formed between them, and the sorting air can be blown upward of the front chaff sheave 62 through the head space S1.
[0042]
In addition, the rear end edge portion 61a of the feed pan 61 is disposed between the first handle cylinder 28 and the second handle cylinder 29, and the front end edge portion of the front chaff sheave 62 is located near and below the rear end edge portion 61a. 62a is arranged.
[0043]
In this way, the grains and sawdust, which are leaked from the first handling cylinder 28, are fed to the front side through the feed pan 61 at an early stage before the leakage is leaked from the second handling cylinder 29. By transferring to the chaff sheave 62, the burden on the front side chaff sheave 62 can be reduced, and the leakage from the second handling cylinder 29 can be smoothly sorted.
[0044]
Further, a Glen pan 63 is disposed below the front chaff sheave 62, and the first and second sorting winds W1, W2 are provided between the first tang 41 and the Glen pan 63 and the front chaff sheave 62 and below the Glen pan 63, respectively. The air is branched through the air passage partition wall 71 and blown.
[0045]
Further, a Glen sheave 64 is disposed adjacent to the rear position of the Glen pan 63, and the Glen sheave 64 has at least a front end edge 64a disposed below the Glen pan 63 to form a head space S2 between the Glen pan 63 and the Glen pan 63. The third selected wind W3 that is formed and blown from the first tang 41 through the air channel partition 72 is branched into the upper and lower portions of the glensh 64 through the head space S2, respectively. The air is blown as W3a and the third lower branch sorting air W3b.
[0046]
In FIG. 3, reference numerals 73, 74, and 75 denote first, second, and third sieve lines. W4 is a sorting air blown from the second tang 60, so that the leakage that leaks from the rear chaff sheave 65 is wind-sorted.
[0047]
In this way, a head space S1 is formed between the feed pan 61 and the front chaff sheave 62, and the first selected wind W1 can be blown above the front chaff sheave 62 through the head space S1, so that the threshing has occurred. When the amount of grain and waste is large, a thick layered body K is formed on the feed pan 61 by the grain and waste and the layered body K flows from the feed pan 61 to the front chaff sheave 62. When the layered body K flows over the head space S1, the layered body K can be discontinuous.
[0048]
As a result, the first sorting wind W1 blown from the first Chinese style 41 blows through the head space S1 to the upper side of the front chaff sheave 62 to perform the wind sorting, so that the rough sorting efficiency by the front chaff sheave 62 can be secured well. In addition, the amount discharged as the third loss can be reduced.
[0049]
Moreover, it is possible to wind-sort grains and swarf that have been roughly sorted by the front chaff sheave 62 and leaked by the second sorting wind W2, and the fine sorting efficiency by the Glen sieve 64 can be improved.
[0050]
Furthermore, since the head space 64 is formed by lowering the position of the front end edge 64a of the grain sheave 64, the third upper branch sorting air W3a is blown between the grain sheave 64 and the front chaff sheave 62 through the head space S2. can do.
[0051]
Therefore, depending on the amount of coarsely selected grains and crumbs, and depending on the type of grain, a thick layered body of grains and crumbs is formed on the grain pan 63. Although it flows on the grain sieve 64, the layered body is dispersed when flowing in the head space S2, and the layered body can be made discontinuous.
[0052]
As a result, when the third upper branch sorting wind W3a blown from the first Chinese potato 41 blows through the head space S2 and above the grain sheave 64 and the front chaff sheave 62, the grains and the waste flowing in the head space S2 And the fine sorting efficiency by the Glen sieve 64 can be improved.
[0053]
Note that the third lower branch sorting wind W3b is for wind-sorting the grains and sawdust leaking from the grain sieve 64, and in particular, the most current grain plate 66 of the first grain receiver 39. It is possible to wind-sort the above grains and sawdust.
[0054]
【The invention's effect】
In the first aspect of the present invention, the first handling cylinder and the second handling cylinder which are axially directed rightward are adjacent to each other in the front-rear direction, a feed pan is disposed below the first handling cylinder, and the second handling cylinder is disposed. A chaff sheave is arranged adjacent to the rear position of the feed pan below the trunk, and a Glen pan and Glen sheave are arranged below the chaff sheave so that the Glen sheave is adjacent to the rear position of the Glen pan, and the Glen sheave is at least at the front edge. The head part is arranged below the Glen pan, a head space is formed between the head and the pan, and the sorting wind is allowed to blow through the head space above and below the Glen sheave, respectively . The rear end edge portion is disposed between the first handling cylinder and the second handling cylinder .
[0060]
In this way, by forming a head space between Glen Sheave and Glen Pan, the sorting wind can be blown between Glen Sheave and Chaff Sheave through the head space, so that the coarsely selected grain and crumb Depending on the type of grain and depending on the type of grain, a thick layered body consisting of grain and sawdust is formed on the grain pan, and the layered body flows from the grain pan to the grain sieve. The same layered body can be made discontinuous.
[0061]
As a result, the sorting wind blown from the tang is blown upward through the head space above the grain sheave and chaff sheave to perform the wind sorting, and the fine sorting efficiency by the grain sheave can be ensured satisfactorily.
[0062]
And the sorting wind blown below the grain sieve, as the final sorting means, reliably sorts the grains and swarf that are finely sorted by the grain sieve and leaks, and recovers the most accurate grain can do.
