It is configured as follows. In addition, 34 is the first cerealing machine and 35 is the second cerealing machine.

Next, the sorting configuration at the rear of the swing sorting shelf 29 will be described with reference to FIG.
A lower shelf plate 41 and an upper shelf plate 42 are disposed so as to be located below the rear portion of the chaff sheave 29c of the swing sorting shelf 29, below the rear portion of the lower grain sheave 29f, and above the second receiving rod 32. The lower shelf plate 41 and the upper shelf plate 42 are attached to the left and right mounting plates 43 and 43 attached to the left and right sides of the rear side portion of the swing sorting shelf 29 so as to swing integrally. The lower shelf 41 extends rearward in a substantially similar rear-upwardly inclined manner so as to extend rearward from the shelf 31b of the first receiving rod 31, and the rear portion thereof is the second receiving portion. It is located above the front side of the collar 32 and is configured to cover the second spiral 32a by the lower shelf 41.

  Further, an upper shelf plate 42 is disposed above the lower shelf plate 41 in the longitudinal direction through a predetermined air passage width, and the upper shelf plate 42 is inclined rearward and has a lower shelf plate. The rear end portions of the shelf boards 41 and 42 are formed as standing portions 41a and 42a that refract and rise upward.

  According to the above configuration, the objects to be sorted that have fallen from the rear part of the chaff sheave 29c and the lower part of the lower grain sieve 29f of the swing sorting shelf 29 are received by the upper shelf board 42 and the lower shelf board 41 that swing together, and the wind sorting and The specific gravity is selected. The material to be sorted from the upper shelf plate 42 is guided to the rear side of the lower shelf plate 41 that is long in the front-rear direction, and again subjected to wind sorting and swing specific gravity sorting. Then, the second item is led to the second receiving rod 32, and the sawdust is discharged rearward.

  For example, as shown in Japanese Utility Model Laid-Open No. 60-38541, the first receptacle is arranged below the chaff sheave and lower glen sieve of the swing sorting shelf, and the second receptacle is arranged behind the first receptacle. It is well known to install and adjust the inclination angle of the first shelf in a gradual manner.

  In such a configuration, if the shelf plate of the first receptacle is adjusted to be steeply inclined, it is difficult for the sorting object to be blown out by the sorting wind and the grains are not easily scattered, but the sorting object becomes clogged, When the slope is adjusted to a gentle slope, the first grain is scattered and sorted into the second catcher, resulting in an increase in the second sort.

  However, by adopting the above-described configuration, the sorting air is raised by the upright portion 42a of the shelf tip of the upper shelf plate 42 and re-sorted while blowing, so that the first grain and the second thing are prevented from being discharged outside the machine. In addition, since the object to be sorted is guided from the upper shelf 42 to the lower shelf 41 and re-sorted, the recovery efficiency of the first grain to the first receptacle 31 and the second item to the second receptacle 32 The collection efficiency can be increased and the sorting accuracy can be increased.

  Further, the standing portion 41a of the lower shelf plate 41 is positioned rearward and lower than the standing portion 42a at the rear end portion of the upper shelf plate 42, and extends to above the second spiral 32a of the second receiving rod 32. Yes. With this configuration, the object to be sorted guided from the upright portion 42a of the upper shelf plate 42 to the second receiving tray 32 side is subjected to wind selection and shaking while increasing the drop at the rear side portion of the lower shelf plate 41. Dynamic specific gravity sorting is performed, and the recovery ratio of the first grain to the first receiving tray 31 can be increased.

  Further, the upright portion 41a of the lower shelf 41 is positioned rearward of the upright portion 42a at the rear end of the upper shelf 42 and extends to above the second spiral 32a of the second receiving rod 32. The height of the standing portion 41 of the lower shelf 41 is substantially the same as or slightly lower than the height of the standing portion 42a of the plate 42.

  By adopting the above-described configuration, foreign matter, keys, and cereals that are not required to be collected in the first receptacle 31 in the sorting object increase a drop from the upper shelf plate 42 to the lower shelf plate 41 and expand in the vertical direction. However, the rearward movement of the second object is smoothed by being guided and wind-selected, and can be smoothly collected from the lower shelf plate 41 to the second receiving bar 32 to increase the selection accuracy.

  Further, the lower end edge of the front end portion of the upper shelf plate 42 is positioned below the rear end portion of the mesh-like lower grain sheave 29f in the swing sorting shelf 29, and the inclined lower end edge of the front side portion of the lower shelf plate 41 is placed on the swing sorting shelf. 29 extends to the front side so as to be located in the lower part of the middle part of the lower grain sieve 29f of the mesh body.

  With the above-described configuration, the object to be sorted that has fallen from the rear end of the lower grain sheave 29f of the swing sorting shelf 29 to the upper shelf 32 jumps at the standing portion 42a while moving backward on the upper shelf 42. As it is raised, it falls to the lower shelf 41 while undergoing wind selection and swinging specific gravity selection, and the grains flow to the lower front side on the lower shelf 41 while being separated from the foreign matter, and are best recovered in the receiving tray 31. Is done.

  In addition, the grains with relatively little adhesion of contaminants that have leaked from the middle part of the mesh-like lower grain sheave 29f of the swing sorting shelf 29f to the front side part of the lower shelf 41 are being wind-selected and the lower inclined end part of the front side part. Therefore, it is possible to reduce the sorting of the grain into the second receiving tray 32 and increase the sorting accuracy.

Next, the swing configuration of the swing sorting shelf 29 will be described with reference to FIGS. 6, 9 and 10.
The lower part of the swing arm 47 is pivotally supported by a horizontal axis on the front side of the sorting box body 46 of the sorting unit 26, and the front side of the swing sorting shelf 29 is attached to the upper end of the swing arm 47 via the bracket 51. The parts are pivotally connected. A swing shaft 48 is mounted on the front side portion of the sorting box 46 in the left-right direction, and the rear side portion of the swing rod 49 is fitted and supported on an eccentric ring 48 a of the swing shaft 48. The front side portion is pin-connected to the midway portion of the swing arm 47. In addition, left and right swing guides 52 and 52 are attached to the rear side left and right sides of the sorting box 46 in a rear-upward inclined manner. It is along the inclination direction of the board and the lower shelf board 41. Left and right support shafts 53 and 53 are attached to the left and right sides of the rear side of the swing sorting shelf 29, and left and right bearings 54 and 54 supported on the left and right support shafts 53 and 53 are fitted and supported on the left and right swing guides 52 and 52, respectively. Yes.

  Thus, when the swing shaft 48 shown in FIG. 10 rotates in the clockwise direction, the swing sorting shelf 29 swings in the direction of the arrow, and the rear side portion of the swing sorting shelf 29 is along the inclination direction of the lower shelf plate 41. Swing back and forth. Therefore, the grain repelling on the lower shelf 41 is reduced, and even if the space between the lower shelf 41 and the upper shelf 42 is narrow, the clogging of the objects to be sorted is reduced and the sorting can be performed smoothly. In addition, since the inclination angle of the upper shelf plate 42 is steeper than the inclination angle of the lower shelf plate 41, the object to be sorted can be swung up and dropped onto the lower shelf plate 41 to enhance the wind selection effect. Moreover, the scattering of the grain from between the shelf board front-end | tip of the most receiving bowl 31 and the lower shelf board 41 can be decreased.

  Further, as shown in FIG. 10, the end side position of the upper shelf plate 42 is positioned in front of the axis of the second spiral 32 a of the second receiving rod 32, and the end side position of the lower shelf plate 41 is received second. It arrange | positions so that it may be located behind the axial center of the 2nd spiral 32a of the collar 32. By setting it as the said structure, the collection | recovery ratio of the first grain in a to-be-sorted item can be raised, and the reduction rate to the 2nd processing chamber 16 of a grain can be decreased.

  Further, as shown in FIG. 11, the inclination angle of the swing guide 52, which is the swing direction of the rear side portion of the swing sorting shelf 29, is θ1, the inclination angle of the upper shelf 42 is θ2, and the lower shelf 41 Assuming that the inclination angle is θ3, even if these angles are set to satisfy θ1 ≦ θ2, θ1 ≧ θ3, and θ2 ≧ θ3, substantially the same effect as the above-described embodiment can be expected.

  Further, as shown in FIGS. 4 and 10, the upper shelf plate 42 is disposed above the left / right swing guides 52, 52, the left / right support shafts 53, 53 and the left / right bearings 54, 54 of the swing sorting shelf 29. The lower shelf plate 41 is arranged in the vicinity of the upper end portions of the left and right swing guides 62 and 52 so as to have substantially the same inclination angle. With the above configuration, the upper shelf plate 42 and the lower shelf plate 41 are disposed above the left and right swing guides 52 and 52, the left and right support shafts 53 and 53, and the left and right bearings 54 and 54 in the sorting air passage 28. Can be screened smoothly while suppressing disturbance. Reference numeral 58 denotes a seal plate that hangs down from the rear end portion of the swing sorting shelf 29 on the shelf plate of the first receiving tray 32, and prevents the grains of the second receiving tray 32 from scattering.

  Further, as shown in FIG. 10, a wide air passage width is provided between the upper shelf plate 42 of the swing sorting shelf 29 and the lower grain sheave 29f in the vertical direction, and the space between the upper shelf plate 42 and the lower shelf plate 41 is provided. A narrow air passage width is provided in the vertical direction. With the above configuration, a large amount of sorting air passes between the upper shelf plate 42 and the lower grain sheave 29f, and the sorting does not deteriorate even if the upper shelf plate 42 is steeply inclined. A large amount of objects to be sorted can be smoothly wind-selected, and the objects to be sorted jump over the lower shelf 41 and can be prevented from falling directly onto the second receiving rod 32, thereby improving the sorting accuracy.

  Further, since the sorting wind between the upper shelf plate 42 and the lower shelf plate 41 rises backward while being blown to the lower shelf plate 41, the air volume is insufficient even if the vertical air passage width is narrow. Moreover, since the lower shelf 41 is inclined more gently than the upper shelf 42, the recovery rate of the first grain to the lower shelf 41 is smaller than that of the upper shelf 42, and the sorting air volume is small. The smallest grain can be selected at least.

  Further, as shown in FIG. 10, a Strollac 29d is disposed at the upper rear part of the upper shelf 42 and the lower shelf 41 of the swing sorting shelf 29, and the front end of the Strollack 29d is exhausted over the entire left and right width. A dust guide plate 56 is attached in a rear-upward inclined shape to cover the front end portion of the Strollac 29d. And the dust-removal guide plate 56 is arrange | positioned rather than the extension line of the standing part 41a of the lower shelf 41 in the back side upper direction.

  With the above-described configuration, the sorting wind that has flowed to the end side of the swing sorting shelf 29 is redirected upward by the standing portion 42a of the upper shelf plate 42 and the standing portion 41a of the lower shelf plate 42, and directed toward the chaff sheave 29c and the stroll rack 29d. Thus, the discharged dust is guided to the dust exhaust fan 33 and can be smoothly discharged out of the machine.

  Further, as shown in FIG. 10, when the upper shelf plate 42 and the lower shelf plate 41 are arranged vertically via a predetermined air passage width, the upper shelf plate 42 is disposed above the lower shelf plate 41 in the middle in the front-rear direction. And a front portion of the upper shelf 42 in the lower shelf 41 is formed into a gently bent mountain shape 41b, and the front side of the lower shelf 41 is configured to be steeply inclined and the rear side is configured to be gently inclined. The space between the upper shelf plate 42 and the lower shelf plate 42 is configured to increase toward the rear side.

  As described above, the air passage width between the upper shelf plate 42 and the lower shelf plate 42 is configured to increase toward the rear side, and the rear side portion of the lower shelf plate 41 is gently inclined, so that the selected air volume is ensured. Thus, the flow of the objects to be sorted can be made smooth. In addition, since the front side portion of the lower shelf 41 is steeply inclined and the rear side is gently inclined, the sorting drop at the rear side of the lower shelf 51 where the objects to be sorted increase increases, and the most grain Recovery is facilitated. In addition, the sorting wind that flows along the steeply inclined front side portion of the lower shelf 41 flows along the lower surface of the upper shelf 42 and acts on the object to be sorted falling from the upper shelf 42 to perform good sorting. be able to.

  Further, as shown in FIG. 10, the rear end of the upper chaff sheave 29c and the rear end of the lower shelf 41 are substantially aligned in the vertical direction, and the end side of the upper shelf 42 is the rear end of the chaff sheave 29c. It arranges ahead of the part. Thus, the sorting wind guided upward by the rising portion 42a of the upper shelf plate 42 and the rising portion 41a of the lower shelf plate 41 acts well on the rear end portion of the chaff sheave 29c, and the chaff sheave plate of the chaff sheave 29c By adjusting the inclination angle loosely, it is possible to reduce the fall of long chopped products onto the upper shelf plate 42 and the lower shelf plate 41 and to reduce the mixing of the chopped product into the first grain.

  Further, the lower grain sheave 29c, the upper shelf plate 42, and the lower shelf plate 41 of the swing sorting shelf 29 may be configured as shown in FIGS. That is, the front end of the upper shelf plate 42 is disposed below the rear end of the lower granule 29f of the swing sorting shelf 29 via a predetermined air passage width, and the same as the rear end of the upper shelf 42. A rear glen sieve 57 having a width is provided, and the lower glen sheave 29f and the rear glen sieve 57 are configured to have substantially the same rear up-tilt angle, and the rear end of the rear glen sieve 57 and the rear end of the chaff sheave 29c are arranged in the vertical direction. Are arranged so that the rear end portion of the rear grain sheave 57 is positioned in front of the rear end portion of the lower shelf 41, and the shelf tip of the lower shelf 41 can be adjusted in the front-rear direction. . In addition, the front side edge part of the rear grain sieve 57 is attached to the lower surface of the rear side edge part of the upper shelf board 42, and the transfer of the object to be sorted from the upper shelf board 42 to the rear grain sieve 57 is made smooth.

  By adopting the above-described configuration, the sorting object guided from the upper shelves 42 to the rear grain sieve 57 is sieved and wind-sorted, and then the lower shelves 41 such as coarse grain cuts, swarfs, keys, etc. It is possible to guide to the second receiving rod 32 while suppressing the falling of the glass to improve the sorting accuracy, and to smoothly sort by suppressing the clogging of the sorting object between the upper shelf plate 42 and the lower shelf plate 41. In addition, since the inclination angle of the lower Glen sheave 29f and the rear Glen sheave 57 is set to be substantially the same rear-upward gentle inclination, the object to be sorted does not stagnate on the rear Glen sheave 57 and flow backward to the lower Glen sheave 29f. Can be sorted smoothly.

  In addition, since the lower glen sieve 29f and the rear glen sieve 57 are arranged below the chaff sheave 29c, long vertical cocoons and coarse grain cuts are less likely to fall on the lower glen sieve 29f and the rear glen sieve 57. Accuracy can be increased.

  Also, a lower glen sheave 29f and a rear gren sheave 57 are arranged below the chaff sheave 29c, and the rear ascending angle of the lower glenve 29f is steeper than the rear ascending angle of the chaff sheave 29c, so A predetermined air passage width is interposed between the shelves 42, and the rear glenve sheave 57 is arranged behind the lower glenve sheave 29 f so as to have the same rear ascending slope and with a step difference.

  According to the above-described configuration, the object to be sorted is smoothly moved from the lower glen sieve 29f to the rear glen sieve 57, and the distance between the chaff sheave 29c and the lower glen sieve 29f is reduced toward the rear side, but the rear end of the chaff sheave 29c is reduced. In this case, a step is provided at the lower side and a rear glen sieve 57 is arranged, and a predetermined air passage width is interposed between the rear end of the lower glen sieve 29f and the upper shelf 42, so that the selected air volume is secured. Sorting can be performed smoothly while avoiding clogging of objects to be sorted.

  Further, by adjusting the shelf tip of the lower shelf board 41 in the front-rear direction, the amount of the object to be sorted dropped from the front end portion of the lower shelf board 41 to the second receiving rod 32 can be adjusted, and the sorting accuracy is improved. be able to.

  Moreover, when adjusting the shelf tip of the lower shelf board 41 in the front-rear direction, it may be adjusted as shown in FIG. That is, the width of the air passage between the rear end portion of the lower grain sheave 29f and the rear side portion of the upper shelf plate 42 is A, and the rear end portion of the rear Glen sheave 57 and the rear end portion of the lower shelf plate 41 are When the interval is B, the shelf tip of the lower shelf board 41 can be adjusted in the front-rear direction so that the relationship of A> B or A≈B can be achieved. Thus, when the number of objects to be selected is small, it is adjusted so as to satisfy the relationship of A> B, and when the number of objects to be selected is large, by adjusting so that the relationship of A≈B is satisfied. Sorting can be performed smoothly while increasing sorting accuracy.

  Moreover, when adjusting the shelf tip of the lower shelf board 41 to the front-back direction, you may comprise as FIG. In other words, the air passage width between the rear end portion of the lower grain sieve 29f and the rear side portion of the upper shelf plate 42 is A, and the rear end portion of the upper shelf plate 42 and the rear end portion of the lower shelf plate 41 are When the interval of C is C, even when the shelf tip of the lower shelf 41 is adjusted to be the shortest, the relationship of A <C is established. Thus, by configuring the interval C to be longer than the interval A, the interval C portion suppresses the slaughtering of the cereals and the falling of the swarf from the rear grain sieve 57 at the front side thereof, thereby improving the grain collection accuracy. be able to.
