After the rotation of passing through thrashing cylinder 16 in paddy stalk 14 is departed from the part of fringe 14a, remaining part is called " stalk ".Stalk, in the conveyance direction downstream side end of paddy stalk conveying mechanism 11, is passed to stalk conveying mechanism 18(Fig. 1 and Fig. 4).
As shown in Figure 4, this stalk conveying mechanism 18 is structures of spread configuration stalk carrier chain 19 and engaging conveyer belt 20 side by side.Stalk carrier chain 19 adopts the chain of ring-type to form, and is recycled driving, thus, is configured to the root of carrying stalk by its lower surface.Engaging conveyer belt 20 is the endless belts that dispose at certain intervals tooth (omitting diagram), by circulation, drives this engaging conveyer belt 20, in the fringe part by tooth engaging paddy stalk, carries.
As shown in Figure 1, below stalk conveying mechanism 18, configure stalk handling part 21.This stalk handling part 21 has the stalk cutting knife that stalk is cut off finely, the disperser that cut stalk is discharged outside machine etc.The stalk being transferred by stalk conveying mechanism 18 is put into stalk handling part 21 successively, after cutting off finely, is positioned over equably farmland.
Below, about being elaborated for the structure that paddy stalk 14 is carried out to threshing.
Thrashing cylinder 16 utilizes metallic plate to make the roughly hollow form cylindrical shell of octagon column to form, and its axis 17 is along the configuration of device fore-and-aft direction (left and right directions of Fig. 2) approximate horizontal ground.In the periphery of thrashing cylinder 16, be outwards provided with highlightedly multiple threshing tooths 22.
As shown in Fig. 2 waits, threshing tooth 22 is provided with multiple along the direction parallel with the axis 17 of thrashing cylinder 16 side by side.As shown in Figure 5, each threshing tooth 22 is formed as flat (flat) shape, so as to be configured to this threshing tooth 22 each other and the parallel plane of column direction.In addition, as shown in Figure 5, the leading section of threshing tooth 22 is configured to towards the roughly V of front end narrowed width word shape.Therefore, adjacent threshing tooth 22 is formed with the V-type groove 23 broadening towards front end width each other.In addition, in the inboard of V-type groove 23, through hole 24 and the described V-type groove 23 of circular (or polygon) conjointly form.
In addition, main body 10 has the top board 27 at the top that forms threshing chamber 15.The lower surface of top board 27 is relative with the outer peripheral face of thrashing cylinder 16.As shown in Figure 3, when axis 17 directions of thrashing cylinder 16 are observed, top board 27 is formed as circular-arc along the rotational trajectory of the front end of threshing tooth 22.In addition, top board 27 approaches the rotation rail slash configuration of the front end of threshing tooth 22.
The thrashing cylinder 16 of present embodiment is configured to threshing type and rotates.That is, as shown in Figure 3, be configured to paddy stalk 14 upward by threshing, the fringe 14a of this paddy stalk 14 is by the top of thrashing cylinder 16.Thus, the fringe of paddy stalk 14 is by between threshing tooth 22 and the lower surface of top board 27.
By above structure, the fringe 14a of the paddy stalk 14 being transferred by paddy stalk conveying mechanism 11 is by the narrow gap between top board 27 and threshing tooth 22.Now, fringe 14a is pushed by the lower surface of top board 27, and embeds threshing tooth 22 part (V-type groove 23 and through hole 24) each other.Under this state, thrashing cylinder 16 rotates, and paddy stalk 14, towards fringe 14a by threshing, departs from the part of fringe 14a and become disconnected fringe from this paddy stalk 14 thus.
In addition, top board 27, at the end 27a in the direction of rotation downstream of thrashing cylinder 16, is connected with the second top board 52.This second top board 52 has formed the top of threshing chamber 15.In addition, the second top board 52 when with the orthogonal cross-section of axis 17 directions of thrashing cylinder 16, have along with the downstream of the direction of rotation of trend thrashing cylinder 16 gradually away from the rotational trajectory of threshing tooth 22 away from portion.Thus, between the rotational trajectory of the front end of the second top board 52 and threshing tooth 22, be formed with space 53.In other words, take the end 27a of top board 27 as starting point, in the direction of rotation of thrashing cylinder 16 compared with the 27a of this end the position of downstream, above thrashing cylinder 16, be formed with space 53.
Like this, in the position of downstream compared with the end 27a of top board 27, be formed with space 53 above thrashing cylinder 16, therefore, after the position of downstream compared with the 27a of end, paddy stalk 14 can depart from from the periphery of thrashing cylinder 16.Thus, paddy stalk 14 is difficult to be wound onto on thrashing cylinder 16, and its result can reduce the load for rotariling actuate thrashing cylinder 16.
The processing of the fringe (disconnected fringe) departing from from paddy stalk 14 about the rotation by thrashing cylinder 16 below, is elaborated.In addition,, in threshing chamber 15, by the rotation of thrashing cylinder 16, except producing disconnected fringe, also produce the dust, grain of stalk bits etc. etc.Below, these mixtures are called to object being treated.

Selection by winnowing fan 41 is configured to and on paddy stalk throughput direction, produces the sorting wind towards downstream, makes this sorting wind blow to grain sieve 42 from downside.
In above structure, the sorting wind that selection by winnowing fan 41 produces is to the thing that is sorted of falling on grain sieve 42.And the heavy object that whether has this sorting wind all generally perpendicularly to fall is that grain is called as single treatment thing.Single treatment thing is imported into conveying plant 43 No. one time, and the little object of proportion is in addition blown and flies towards paddy stalk conveyance direction downstream side.
The single treatment thing (grain) that is imported into a conveying plant 43 is transferred by this conveying plant 43, and is stored in and for example omits illustrated grain collecting box.By with upper type, can be from being sorted thing sorting and taking out grain.
Below the end of downstream side of glume-shell screen 39 and grain sieve 42, dispose the second-pumping device 44 forming as helix transporting device.
Stay disconnected fringe on glume-shell screen 39, stalk bits etc. and carried towards the downstream of paddy stalk throughput direction by the reciprocally swinging of this glume-shell screen 39, and fall second-pumping device 44.In addition, falling the sorting wind that passes through selection by winnowing fan 41 in the object being treated on grain sieve 42 is blown the disconnected fringe that flies, stalk bits etc. and is also fallen on second-pumping device 44.Wind sorting portion 38 has Air Blast fan 45, and it makes towards conveyance direction downstream side wind upwards to the thing that is sorted of falling on second-pumping device 44.
Fall being sorted of second-pumping device 44 and be with disconnected fringe kernelly etc. heavier in thing, therefore whether have the wind of Air Blast fan 45 all fall and be imported into second-pumping device 44.On the other hand, stalk bits with grain etc. are not blown by the wind of Air Blast fan 45 and are flown, and by attracting fan 51 to be discharged to outside device.
The leeway that has enforcement and process and take out grain with disconnected fringe kernelly etc., therefore has recovery value.The object that becomes like this object of processing is again called to after-treatment thing.By 38 sortings of wind sorting portion the after-treatment thing that is imported into second-pumping device 44, by this second-pumping device 44, be transferred, and be fed into the end of secondary reduction conveying plant (secondary reduction mechanism) 46.
Secondary reduction conveying plant 46 is along the helix transporting device that roughly above-below direction configures, and described after-treatment thing is transported to top side compared with the fringe treating apparatus 29 that breaks.The after-treatment thing being transferred by secondary reduction conveying plant 46 is released and is put into disconnected fringe treating apparatus 29 from the discharge port 47 of this secondary reduction conveying plant 46.By above structure, can to the after-treatment thing that is sorted device 36 sortings, process again by disconnected fringe treating apparatus 29.
Below, about the distinctive structure of present embodiment, describe.
As mentioned above, in sheller unit in the past, the situation that exists the object being treated in disconnected fringe treating apparatus to fly out to thrashing cylinder side because of the energy of the rotation of process cartridge.Especially, the sheller unit 1 of present embodiment is to make the structure of process cartridge to the direction rotation identical with the thrashing cylinder 16 of upper threshing type, the situation that therefore exists object being treated easily to fly out to thrashing cylinder 16 from the terminal of screen cloth 31.
Therefore, the sheller unit 1 of present embodiment is the structure that is provided with dividing plate 34 between thrashing cylinder 16 and process cartridge 30.
This dividing plate 34 consists of the metallic plate of atresia, and object being treated can not pass through this dividing plate.As shown in Figure 3, when observing with the orthogonal direction of the axis 32 of process cartridge 30, dividing plate 34 is configured to block the straight line that the axis 32 of the axis of thrashing cylinder 16 17 and process cartridge 30 is linked.In addition, as shown in Figure 4, dividing plate 34 is arranged in the whole total length of axis 17 directions of thrashing cylinder 16 at least.And as shown in Figure 3, the terminal that the bottom of dividing plate 34 approaches screen cloth 31 configures (end in the downstream in the direction of rotation of process cartridge 30).
Above, in the mode between partial closure's thrashing cylinder 16 and process cartridge 30, configure dividing plate 34, therefore can prevent that object being treated in disconnected fringe treating apparatus 29 from flying out to thrashing cylinder 16 sides because of the energy of the rotation of process cartridge 30.Thus, can improve the treatment effeciency of disconnected fringe treating apparatus 29.
In addition, in the present embodiment, as shown in Figure 3, the upper end of dividing plate 34 is set at than the high position, upper end of the rotational trajectory of the front end of processing tooth 33.Like this, the upper end of dividing plate 34 is arranged on than processing the high position of tooth 33, therefore the object being treated in disconnected fringe treating apparatus 29 is difficult to leap dividing plate 34 tops and flies out to thrashing cylinder 16 sides.
In addition, at least a portion of the face towards process cartridge 30 sides of dividing plate 34 court oliquely downward.Like this, by least a portion of dividing plate 34 is configured obliquely with respect to plumb line, can prevent that the object being treated in disconnected fringe treating apparatus 29 from flying out to thrashing cylinder 16 sides by the respond well of " hangnail " thus.
The lower end of dividing plate 34 approach screen cloth 31 terminal configure.In addition, as mentioned above, in the terminal of screen cloth 31, be formed with cutting 49(therefore, can near the bottom of dividing plate 34, configure cutting 49).By this cutting 49, object being treated is cut off to processing, therefore in the part of this cutting 49, produce stalk bits in small, broken bits.The energy that the stalk producing is like this considered the rotation because processing tooth 33 to be worth doing easily disperses.The sheller unit 1 of present embodiment is configured in dividing plate 34 from cutting 49 the direction of rotation downstream of process cartridge 30, even if therefore produce stalk in small, broken bits bits by cutting 49, disperses, and also can prevent that them from dispersing to thrashing cylinder 16 sides.
Then the first object being treated guided plate (the first guide portion) 35, having about the sheller unit of present embodiment describes.
As mentioned above, the object being treated being produced by thrashing cylinder 16 is released towards the space 53 of the top that is formed on thrashing cylinder 16 by the energy of the rotation of thrashing cylinder 16.Now, the whole object being treated being produced by thrashing cylinder 16 is put into disconnected fringe treating apparatus 29, but when the object being treated that is released to space 53 does not disperse along track flight by the phase of giving, this object being treated is not put into disconnected fringe treating apparatus 29, has the situation of the Efficiency Decreasing of sheller unit 1 entirety.
Especially, in the sheller unit 1 of present embodiment, owing to being provided with dividing plate 34 between thrashing cylinder 16 and process cartridge 30, so the part, space between thrashing cylinder 16 and process cartridge 30 is blocked.Its result, the entrance that leads to disconnected fringe treating apparatus 29 becomes narrow, and object being treated is difficult to enter disconnected fringe treating apparatus 29.
Therefore, the sheller unit 1 of present embodiment is provided with the first object being treated guided plate 35 that the object being treated being produced by thrashing cylinder 16 is directed to the process cartridge 30 of disconnected fringe treating apparatus 29.
Below, be elaborated.In addition, in the following description, during referred to as " upstream side ", " downstream ", refer to upstream side and downstream in the direction of rotation of thrashing cylinder 16.
This first object being treated guided plate 35 is metal plate-shaped members, is formed as illustrated in fig. 7 roughly oblong-shaped.As shown in Figure 4, the first object being treated guided plate 35 is configured to its length direction along the axis 17 directions configurations of thrashing cylinder 16 and can be in the face of the total length of axis 17 directions of thrashing cylinder 16.
As shown in Figure 3, the first object being treated guided plate 35 is configured in downstream compared with the end of downstream side 27a of top board 27.Therefore, can say that this first object being treated guided plate 35 is configured in downstream compared with being formed on the starting point away from portion (end of the upstream side of the second top board 52) of top of thrashing cylinder 16.In addition, this first object being treated guided plate 35 is configured in the position of the object being treated collision of emitting to space 53 from thrashing cylinder 16.Therefore,, once the object being treated being produced by thrashing cylinder 16 is because the energy of the rotation of this thrashing cylinder 16 is released in space 53, collide with the first object being treated guided plate 35 afterwards.
The first object being treated guided plate 35 is configured in compared with process cartridge 30 by upstream side and above this process cartridge 30.And, in the first object being treated guided plate 35, by the oliquely downward configuration that faces of thrashing cylinder 16 sides.Therefore, the lower surface of the object being treated of emitting from thrashing cylinder 16 and the first object being treated guided plate 35 (towards face oliquely downward) collision, and to the bottom of this first object being treated guided plate 35 towards direction (tiltedly below) directed.
The first object being treated guided plate 35 is configured by the mode of top side's position compared with the upper end of dividing plate 34 with the face towards thrashing cylinder 16 sides (lower surface).Because the first object being treated guided plate 35 configures like this, so can pass through reliably the top of dividing plate 34 by the directed object being treated of the lower surface of this first object being treated guided plate 35.Thus, can the object being treated of emitting to space 53 from thrashing cylinder 16 be directed in disconnected fringe treating apparatus 29 by the first object being treated guided plate 35.
In addition, between the upper end of the first object being treated guided plate 35 and the end face of threshing chamber 15, seal and seamlessly form.More particularly, between the upper end of the first object being treated guided plate 35 and the end face of threshing chamber 15, being closed plate 55 seals.Thus, the top that can not streak the first object being treated guided plate 35 due to object being treated, so can guide reliably object being treated by the first object being treated guided plate 35.
In addition, (omit diagram) fixed and is fixed on the lower end of described closure plate 55 in the upper end of the first object being treated guided plate 35 by screw.Like this, the first object being treated guided plate 35 of present embodiment forms with the shell split ground of threshing chamber 15, and is fixedly fixed by screw thread.Therefore, this first object being treated guided plate 35 can dismounting by removing the fastening of described screw.That is,, because of the object being treated frequent impact of grain etc., the first object being treated guided plate 35 is easy parts of wearing and tearing.Therefore, making as described above can dismounting, can change worn out the first object being treated guided plate 35.In addition, in the present embodiment, the lower end of the first object being treated guided plate 35 is not fixed especially, is freely.
In addition, in the first object being treated guided plate 35, on its lower surface (towards the face of thrashing cylinder 16 sides), multiple adjustment plates 56 are installed.This adjustment plate 56 consists of the metal plate-shaped member bending with approximate right angle as illustrated in fig. 7, from the direction towards roughly orthogonal towards thrashing cylinder 16 sides of the first object being treated guided plate 35, arranges highlightedly.
As shown in the section plan of Fig. 4, multiple adjustment plates 56 configure side by side along the direction (left and right directions of Fig. 4) parallel with the axis 32 of process cartridge 30.And, respectively adjust plate 56 and configure obliquely with respect to the direction parallel with the axis 32 of process cartridge 30.
In above structure, the object being treated flying out from thrashing cylinder 16, when colliding with the first object being treated guided plate 35, is imported to disconnected fringe treating apparatus 29 directed time by adjusting direction that plate 56 tilts to axis direction with respect to process cartridge 30.Like this, by the adjustment plate 56 configuring obliquely, guide object being treated, thus, can make this object being treated disperse on the axis direction of process cartridge 30.Thus, prevent that object being treated is intensively supplied to the ad-hoc location of process cartridge 30, can adjust equably the axial distribution of the object being treated that process cartridge 30 supplies with.Therefore, can on the axis direction of process cartridge 30, effectively utilize disconnected fringe treating apparatus 29.
As mentioned above, the sheller unit 1 of present embodiment has thrashing cylinder 16, process cartridge 30, the first object being treated guided plate 35 and dividing plate 34.Thrashing cylinder 16 rotates centered by the axis 17 of setting approximate horizontal for upper threshing type, and in periphery, has multiple threshing tooths 22.Process cartridge 30 by by axis 17 almost parallels of thrashing cylinder 16 and be set in the axis 32 of the position lower than axis 17 centered by rotation, and in periphery, there are multiple processing teeth 33.The first object being treated guided plate 35 guides by lower surface the object being treated being produced by thrashing cylinder 16 to process cartridge 30.Dividing plate 34 is configured between thrashing cylinder 16 and process cartridge 30.The upper end of dividing plate 34 is set at than the high position, upper end of the rotational trajectory of the front end of processing tooth 33.The first object being treated guided plate 35 is configured by the mode of top side compared with the upper end of dividing plate 34 with described lower surface.
Like this, between thrashing cylinder 16 and process cartridge 30, dividing plate 34 is set, the upper end that makes this dividing plate 34 is than processing the high position of tooth 33, therefore can stoping object being treated to fly out to thrashing cylinder 16 from process cartridge 30.In addition, owing to adopting, by the first object being treated guided plate 35, guide the structure of object being treated, so this object being treated can be dropped into process cartridge 30 swimmingly.By above structure, can process reliably the object being treated being produced by thrashing cylinder 16 by process cartridge 30, therefore can improve the efficiency of sheller unit entirety.
Then the second object being treated guided plate (the second guide portion) 63, having about the sheller unit 1 of present embodiment describes.
As already described, the sheller unit 1 of present embodiment is to be guided the object being treated of emitting from thrashing cylinder 16 and guided to the structure of disconnected fringe treating apparatus 29 by the lower surface of the first object being treated guided plate 35.But, in fact, the object being treated being produced by thrashing cylinder 16 be not all by the first object being treated guided plate 35, guided and draw enter disconnected fringe treating apparatus 29 desirable track fly.For example, shown in the Reference numeral 61 of Fig. 3, in the case of the parts collision beyond object being treated and the first object being treated guided plate 35, this object being treated is to unforeseen direction resilience.In the case of object being treated does not draw desirable track and flies, likely this object being treated fails to enter disconnected fringe treating apparatus 29, and by falling between process cartridge 30 and thrashing cylinder 16.
Therefore, the sheller unit 1 of present embodiment is provided with the second object being treated guided plate 63 of the object being treated being produced by thrashing cylinder 16 upper surface being caught and being guided to disconnected fringe treating apparatus 29.
This second object being treated guided plate 63 is configured between thrashing cylinder 16 and process cartridge 30.More correctly, as shown in Figure 3, while observing from axis 32 directions of process cartridge 30, between the plumb line at the axis 17 center by thrashing cylinder 16 and the plumb line at the axis 32 center by process cartridge 30, configure the second object being treated guided plate 63.The second object being treated guided plate 63 is configured in compared with process cartridge 30 by upstream side in the direction of rotation of thrashing cylinder 16.In addition, the second object being treated guided plate 63 is configured in lower than the upper end of the periphery of thrashing cylinder 16 and higher than the upper end of the periphery of process cartridge 30 position.Above, due to the second object being treated guided plate 63 is configured between thrashing cylinder 16 and process cartridge 30, so can utilize the upper surface of the second object being treated guided plate 63 to catch to want the object being treated falling by between thrashing cylinder 16 and process cartridge 30.
In the present embodiment, the second object being treated guided plate 63 is metallic plates, and its upper surface roughly forms smoothly and formed guide surface 63a.As shown in Figure 3, while observing from axis 32 directions of process cartridge 30, the guide surface 63a of the second object being treated guided plate 63 is inclined relative to horizontal and configures.More particularly, with the end of process cartridge 30 sides of guide surface 63a, than the low mode in end of thrashing cylinder 16 sides, configure.Like this, guide surface 63a configures obliquely in the mode of process cartridge 30 side step-downs, and the object being treated of therefore being caught by guide surface 63a is guided naturally towards process cartridge 30.
In addition, as shown in Figure 3, with the end of process cartridge 30 sides of guide surface 63a, configure with the mode that the upper end of dividing plate 34 is connected.Due to guide surface, 63a configures by this way, so can pass through the top of dividing plate 34 by the directed object being treated of this guide surface 63a.Its result, can be by the object being treated of being caught by this guide surface 63a to the interior importing of disconnected fringe treating apparatus 29.
As mentioned above, the sheller unit 1 of present embodiment is arranged between thrashing cylinder 16 and process cartridge 30 the second object being treated guided plate 63 of the object being treated being produced by thrashing cylinder 16 upper surface being caught and being guided to process cartridge 30.
By the second object being treated guided plate 63 is set like this, can prevents that untreated object being treated is by falling between thrashing cylinder 16 and process cartridge 30, and can catch this object being treated and guide to process cartridge 30.
Then the spiral guide member 65, having about the disconnected fringe treating apparatus 29 of present embodiment describes.This spiral guide member 65 is carried the object being treated in disconnected fringe treating apparatus 29 along axis 32 directions of process cartridge 30.
As shown in Figure 3, spiral guide member 65 is configured between process cartridge 30 and dividing plate 34.As shown in Figure 8, spiral guide member 65 is flat parts.In addition, the disconnected fringe treating apparatus 29 of present embodiment has multiple described spiral guide members 65.Multiple spiral guide members 65 configure in parallel to each other, and in the direction parallel with the axis 32 of process cartridge 30, separate suitable compartment of terrain and configure side by side.
As shown in Figure 3, while observing from axis 32 directions of process cartridge 30, the contour shape of the end face of process cartridge 30 sides of spiral guide member 65 is formed as roughly circular-arc along the rotational trajectory of the front end of processing tooth 33.In addition, spiral guide member 65 is configured in compared with processing the rotational trajectory of front end of tooth 33 in the outer part.Thus, spiral guide member 65 is not interfered with the processing tooth 33 of rotation.
And as shown in Fig. 4 and Fig. 9, tabular spiral guide member 65 configures obliquely with respect to the direction parallel with the axis 32 of process cartridge 30 (device fore-and-aft direction).
Configure as described above spiral guide member 65, the end face relative with process cartridge 30 that it can be said that each spiral guide member 65 is roughly along the configuration spirally centered by the axis 32 by this process cartridge 30.In addition, in the present embodiment, the mode of the spiral of the left hand direction of spiral guide member 65 centered by the axis 32 along by process cartridge 30 configures.
Spiral guide member 65 roles to configuration as described above describe.
Object being treated in disconnected fringe treating apparatus 29, along with process cartridge 30 and the processing tooth 33 of rotation, rotates around axis 32 in disconnected fringe treating apparatus 29.The object being treated rotating around axis 32 is like this when passing through between process cartridge 30 and dividing plate 34, directed by spiral guide member 65, and moves along this spiral guide member 65.Spiral guide member 65 is along the configuration spirally centered by the axis 32 by process cartridge 30, and the object being treated therefore being guided by this spiral guide member 65 moves along this spiral.
As mentioned above, spiral guide member 65 configures along left-handed spiral.In addition, in the disconnected fringe treating apparatus 29 of present embodiment, as shown in Figure 3, process cartridge 30 from device face side (front side) observe left (counterclockwise) form rotatably.Therefore the object being treated, being guided by spiral guide member 65 disconnected fringe treating apparatus 29 interior by towards device rear (downstream on paddy stalk throughput direction) carry.
Like this, the object being treated in disconnected fringe treating apparatus 29 can be carried along the axis 32 of process cartridge 30, therefore can be made the object being treated in disconnected fringe treating apparatus 29 disperse in axis 32 directions of process cartridge 30.For example, the amount of object being treated of being put into disconnected fringe treating apparatus 29 from thrashing cylinder 16 is more the closer to device front side (upstream side on paddy stalk throughput direction), and the amount of object being treated that is put into device rear side (downstream on paddy stalk throughput direction) is less.Therefore, by spiral guide member 65, the object being treated in disconnected fringe treating apparatus 29 is carried towards device rear as described above, thus, can be made this object being treated disperse on the axis direction of process cartridge 30.Thus, can effectively utilize equably disconnected fringe treating apparatus 29 in the whole total length of process cartridge 30, therefore can improve the treatment effeciency of this disconnected fringe treating apparatus 29.
Object being treated in disconnected fringe treating apparatus 29 during being carried towards device rear, the effect of the processing tooth 33 that can be rotated in multiple times, the therefore contained grain coverlet granulation of this object being treated, and stalk bits are shredded.Grain or the stalk bits that become in small, broken bits drop to sorting unit 36 by screen cloth 31.On the other hand, the final rearward end (end in the downstream on paddy stalk throughput direction) that is not arrived disconnected fringe treating apparatus 29 by the large dust of choppingization.
As shown in Fig. 4, Fig. 8 and Fig. 9, in the rearward end of process cartridge 30, be provided with the blade 68 of dishing out rotating integratedly with this process cartridge 30.This blade 68 of dishing out is the tabular parts that configure abreast with the axis 32 of process cartridge 30, in the outstanding mode of the surrounding from process cartridge 30, is provided with multiple.In addition, in a part for this blade 68 of dishing out, screen cloth 31 is not set.That is to say, the below of the blade 68 of dishing out is open.
As shown in Figure 6, below the blade 68 of dishing out, be provided with the separation member 73 that swings sorting portion 37.As shown in Figure 4, separation member 73 is that a large amount of thread-like member (wire) 69 is separated to suitable compartment of terrain structure arranged side by side abreast on left and right directions at device.As shown in Figure 6, separation member 73 is configured in the top of glume-shell screen 39.
In above structure, the object being treated (large dust etc.) that is transported to rearward end in disconnected fringe treating apparatus 29 is dished out downward by the rotation of the blade 68 of dishing out, and falls on separation member 73.Now, large dust etc. is stuck in thread-like member 69 and stays on separation member 73.At grain, sneak into the object being treated of falling on separation member 73, this grain is by falling on glume-shell screen 39 between thread-like member 69.Finally fall object being treated (large dust etc.) on separation member 73 and be attracted fan 51 and attract, and be discharged to outside machine.
In addition the object being treated falling from the rearward end of disconnected fringe treating apparatus 29, becomes by the energy of the rotation of the blade 68 of dishing out the state expanding along device left and right directions.Therefore, the large block object being treated that sticks together can not fallen on separation member 73.Thus, can prevent that grain from sneaking into is discharged to the outer such loss of machine indissociably in the block dust that sticks together.
As mentioned above, in the sheller unit 1 of present embodiment, disconnected fringe treating apparatus 29 has the spiral guide member 65 that relatively configures with the side face of process cartridge 30 and roughly configure along the spiral centered by the axle by described process cartridge 30.
By spiral guide member 65 is set like this, can the axial conveying along process cartridge 30 by the object being treated in disconnected fringe treating apparatus 29.Thus, can prevent that large dust is trapped in disconnected fringe treating apparatus 29, and can improve the treatment effeciency of this disconnected fringe treating apparatus 29.
Then,, in the sheller unit of present embodiment, about the structure of processing after-treatment thing by disconnected fringe treating apparatus 29, describe.The sheller unit 1 of present embodiment is provided with the secondary boot path 48 that drops into disconnected fringe treating apparatus 29 when the after-treatment thing edge direction parallel with the axis 32 of process cartridge 30 that the discharge port from secondary reduction conveying plant 46 47 is emitted guides.
Below, be elaborated.As shown in Fig. 3, Fig. 4 and Figure 10, secondary boot path 48 is as consist of (in addition,, in Fig. 4, for representing the inside of secondary boot path 48, having omitted top 72) bottom surface 70, sidewall 71 and 72 spaces that surround, top.As shown in Fig. 4 and Figure 10, at the discharge port 47 of one end of the length direction of secondary boot path 48 connecting secondary reduction conveying plant 46.By this structure, by secondary reduction conveying plant 46, be transferred the after-treatment thing coming and be released in secondary boot path 48.
As shown in figure 10, the length direction of secondary boot path 48 is inclined relative to horizontal and configures.Described discharge port 47 is connected a high side's of the secondary boot path 48 of configuration end obliquely.The after-treatment thing of therefore, emitting from discharge port 47 is guided to a low side along the length direction of secondary boot path 48 naturally by the effect of gravity.As shown in Figure 4, overlook while observing, the length direction of secondary boot path 48 roughly configures along axis 32 ground of process cartridge 30.The after-treatment thing of therefore, emitting from discharge port 47 is roughly directed along the axis 32 of process cartridge 30 by secondary boot path 48.
As shown in Figure 3, with the orthogonal cross section of the axis 32 of process cartridge 30 on, the end of a side of the bottom surface 70 of secondary boot path 48 is sealed by sidewall 71, the open-ended of opposite side.In addition, in the following description, the end of a side of the opening of bottom surface 70 is called to open end, the end of a side of being sealed by sidewall 71 is called to blind end.As shown in Figure 3, with the orthogonal cross section of the axis 32 of process cartridge 30 on, 70Yi open end, the bottom surface mode lower than blind end is inclined relative to horizontal and configures.In above structure, below the interior directed after-treatment thing of secondary boot path 48 can drop to from the open end of bottom surface 70.
As shown in Figure 3, secondary boot path 48 is configured in than the high position of disconnected fringe treating apparatus 29.And upper with the orthogonal cross section (Fig. 3) of the axis 32 of process cartridge 30, the open end of the bottom surface 70 of secondary boot path 48 is positioned at the top at the top (end of the upstream side in the direction of rotation of process cartridge 30) of the screen cloth 31 of disconnected fringe treating apparatus 29.In addition, 70Yi Qi open end, described bottom surface configures towards the mode of process cartridge 30.In above structure, the after-treatment thing falling from the open end of bottom surface 70 is by the interior input of disconnected fringe treating apparatus 29.
As shown in Figure 4, overlook while observing, secondary boot path 48 forms in the mode of the narrowed width along with away from discharge port 47, bottom surface 70.In addition, as mentioned above, 70Yi open end, the bottom surface mode lower than blind end configures obliquely.Therefore, at the interior directed after-treatment thing of secondary boot path 48, sooner or later from the open end of bottom surface 70, fall.By above structure, the after-treatment thing of emitting from discharge port 47 is directed in the direction of the interior axis 32 along process cartridge 30 of secondary boot path 48, from the open sides end of bottom surface 70, falls and by the interior input of disconnected fringe treating apparatus 29 simultaneously.
Speed or the direction of the after-treatment thing of emitting from discharge port 47 are various, and therefore some after-treatment thing is fallen the position that approaches discharge port 47, and some after-treatment thing is fallen the position away from discharge port 47.Therefore, after-treatment thing is moderately disperseed in axis 32 directions of process cartridge 30 by the position of dropping into disconnected fringe treating apparatus 29.
Like this, by the axis 32 along process cartridge 30 roughly, secondary boot path 48 is set, on the basis that can make the after-treatment thing of emitting from the discharge port 47 of secondary reduction conveying plant 46 disperse in axis 32 directions of process cartridge 30, to disconnected fringe treating apparatus 29, supplies with.Thus, can prevent that after-treatment thing is intensively supplied to the specific position of disconnected fringe treating apparatus 29, can effectively utilize this disconnected fringe treating apparatus 29 in whole total length.
In addition, in the present embodiment, as shown in Figure 4, the discharge port 47 of secondary reduction conveying plant 46 forms in the mode of emitting after-treatment thing from downstream towards upstream side on the throughput direction at paddy stalk 14.In addition, the bottom surface 70 of secondary boot path 48 on the throughput direction of paddy stalk 14, its width along with from downstream upstream side narrow gradually.And this bottom surface 70 is not formed into the upstream-side-end (that is, bottom surface 70 disconnects halfway) of process cartridge 30 on the throughput direction of paddy stalk 14.By above structure, secondary boot path 48 is supplied to after-treatment thing the upstream side of disconnected fringe treating apparatus 29 hardly.
