Detailed description of the invention

Hereinafter, with reference to the accompanying drawings of embodiments of the present invention.As it is shown in figure 1, the sheller unit 1 of present embodiment has main body 10 and the paddy stalk conveying mechanism 11 of the sidepiece being arranged on main body 10.

As it is shown on figure 3, paddy stalk conveying mechanism 11 has paddy stalk carrier chain 12 and push part 13.Paddy stalk carrier chain 12 is configured to ring-type as illustrated in fig. 1, is circulated driving by the rotation of sprocket wheel.Push part 13 is configured to be pushed relative to the upper surface of paddy stalk carrier chain 12 as illustrated in fig. 3.

Paddy stalk 14 is to sandwich its root to be kept (with reference to Fig. 3) between upper surface and the push part 13 of paddy stalk carrier chain 12.In this condition, driving paddy stalk carrier chain 12 by circulating, paddy stalk 14 is carried by paddy stalk conveying mechanism 11 from lateral device rear, device front.Additionally, in the following description, the direction of paddy stalk 14 will be carried referred to as paddy stalk conveying direction by paddy stalk conveying mechanism 11.

In the inside of main body 10, mainly it is configured with threshing chamber 15, sorting unit 36 and straw process portion 21.

Threshing chamber 15 is the space of the threshing for carrying out paddy stalk 14.As shown in Figures 1 and 2, in the face side (left side of Fig. 1 and Fig. 2) of main body 10, it is formed for by the fringe 14a of the paddy stalk 14 paddy stalk throw-in part 25 imported to the inside of threshing chamber 15.The fringe 14a of the paddy stalk 14 being transferred by paddy stalk conveying mechanism 11 is directed to the inside of threshing chamber 15 via paddy stalk throw-in part 25.In threshing chamber 15, it is configured with thrashing cylinder 16 and disconnected fringe processes device 29.

The structure of the tubular that thrashing cylinder 16 is its axis 17 to be configured abreast with the fore-and-aft direction (left and right directions of Fig. 2) of sheller unit 1, is being provided with threshing tooth 22 described later about.This thrashing cylinder 16 is driven in rotation around axis 17.As shown in Figure 4, paddy stalk carrier chain 12 is configured to during vertical view almost parallel with the axis 17 of thrashing cylinder 16.Thus, paddy stalk conveying mechanism 11 carries paddy stalk 14 along the axis 17 of thrashing cylinder 16.Now, the threshing tooth 22 of the thrashing cylinder 16 by rotating, the part of fringe 14a is departed from from the paddy stalk 14 being transferred.The part of the fringe 14a being now taken off is called " disconnected fringe ".

Remaining part after being partially disengaged of fringe 14a will be called " straw " by rotating of thrashing cylinder 16 by paddy stalk 14.Straw, in the conveyance direction downstream side end of paddy stalk conveying mechanism 11, is passed to straw conveying mechanism 18(Fig. 1 and Fig. 4).

As shown in Figure 4, this straw conveying mechanism 18 is the structure of spread configuration straw carrier chain 19 and locking conveyer belt 20 side by side.Straw carrier chain 19 adopts the chain of ring-type to constitute, and is driven by circulation, thus, is configured to be carried the root of straw by its lower surface.Locking conveyer belt 20 is the endless belt being configured with tooth (omitting diagram) at certain intervals, drives this locking conveyer belt 20 by circulating, carries while the fringe part by the locking paddy stalk of tooth.

As it is shown in figure 1, in the straw process portion 21 configured under of straw conveying mechanism 18.This straw process portion 21 have straw is cut off finely straw cutting knife, by cut-off straw to the disperser etc. discharged outside machine.The straw being transferred by straw conveying mechanism 18 is put into straw process portion 21 successively, after cutting off finely, is evenly placed in farmland.

Hereinafter, it is described in detail about the structure being used for paddy stalk 14 is carried out threshing.

Thrashing cylinder 16 is to utilize metallic plate to be made the hollow form cylinder of substantially octagon column and constitute, and its axis 17 substantially horizontally configures along device fore-and-aft direction (left and right directions of Fig. 2).In the periphery of thrashing cylinder 16, outwardly it is provided with multiple threshing tooth 22.

As shown in Fig. 2 etc., threshing tooth 22 is provided with multiple along the direction parallel with the axis 17 of thrashing cylinder 16 side by side.As it is shown in figure 5, each threshing tooth 22 is formed as flat (flat) shape, in order to be configured to the plane parallel with this threshing tooth 22 direction alongside one another.It addition, as it is shown in figure 5, the leading section of threshing tooth 22 is configured to the substantially V shape narrowed towards nose width.Therefore, adjacent threshing tooth 22 is formed with the V-groove 23 broadened towards nose width each other.It addition, in the inboard of V-groove 23, through hole 24 and the described V-groove 23 of circular (or polygon) are conjointly formed.

It addition, main body 10 has the top board 27 at the top constituting threshing chamber 15.The lower surface of top board 27 is relative with the outer peripheral face of thrashing cylinder 16.As it is shown on figure 3, when observing in axis 17 direction of thrashing cylinder 16, top board 27 is formed as arc-shaped along the rotational trajectory of the front end of threshing tooth 22.It addition, top board 27 configures close to the rotation rail slash of the front end of threshing tooth 22.

The thrashing cylinder 16 of present embodiment rotates with being configured to upper threshing type.That is, as it is shown on figure 3, be configured to paddy stalk 14 upward by threshing, the fringe 14a of this paddy stalk 14 top by 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-groove 23 and through hole 24) each other.In this condition, thrashing cylinder 16 rotates, and thus paddy stalk 14 is towards fringe 14a by threshing, the part of fringe 14a is departed from from this paddy stalk 14 and becomes disconnected fringe.

It addition, top board 27 is at the end 27a in the direction of rotation downstream of thrashing cylinder 16, it is connected with the second top board 52.This second top board 52 constitutes the top of threshing chamber 15.It addition, when the second top board 52 is from orthogonal with axis 17 direction of thrashing cylinder 16 cross-section, there is the downstream along with the direction of rotation tending to thrashing cylinder 16 and be gradually distance from threshing tooth 22 rotational trajectory away from portion.Thus, between the rotational trajectory of the second top board 52 and the front end of threshing tooth 22, it is formed with space 53.In other words, with the end 27a of top board 27 for starting point, in the direction of rotation of thrashing cylinder 16 compared with this end 27a the position of downstream, be formed above space 53 at thrashing cylinder 16.

Like this, in the position of downstream compared with the end 27a of top board 27, being formed above space 53 at 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 it is as a result, it is possible to reduce for rotating the load driving thrashing cylinder 16.

Hereinafter, it is described in detail about by the process rotating the fringe (disconnected fringe) from paddy stalk 14 disengaging of thrashing cylinder 16.Additionally, in threshing chamber 15, by the rotation of thrashing cylinder 16, except producing disconnected fringe, also produce the dust of stalk bits etc., grain etc..Hereinafter, these mixture are called treated object.

It is released by the direction of rotation downstream being rotated towards thrashing cylinder 16 of this thrashing cylinder 16 by the treated object produced that rotates of thrashing cylinder 16.As it has been described above, in the present embodiment, it is formed above space 53 at thrashing cylinder 16.Therefore, the treated object released from thrashing cylinder 16 flies out towards described space 53, falls while drawing the track of regulation in this space 53.As it is shown on figure 3, at the drop-off positions of treated object, be configured with disconnected fringe and process device 29.As shown in Figures 3 and 4, disconnected fringe process device 29 has process cartridge 30 and screen cloth 31.

Process cartridge 30 is shaped generally as four rib tubulars, and is configured to be driven in rotation around its axis 32.The axis 32 of process cartridge 30 configures substantially in parallel with the axis 17 of thrashing cylinder 16.Additionally, in the present embodiment, as shown by arrows in Figure 3, thrashing cylinder 16 is rotated driving with process cartridge 30 to identical direction.This process cartridge 30 has multiple process teeth 33 outwardly.As shown in Figure 4, multiple process teeth 33 configure side by side along the direction parallel with the axis 32 of process cartridge 30.

Screen cloth 31 is arranged in the way of the latter half of covering treatment cylinder 30.As it is shown on figure 3, when observing from axis 32 direction of process cartridge 30, screen cloth 31 is formed along the track of the front end processing tooth 33 rotated.

In the structure shown here, thrashing cylinder 16 treated object produced is imported into disconnected fringe and processes device 29.This treated object is subject to kneading action between the process tooth 33 and the screen cloth 31 that rotate, promotes simple grain (grain is taken off).Fallen downwards by screen cloth 31 by the grain of threshing.It addition, the terminal at screen cloth 31 is formed with cutting 49.This cutting 49 is formed multiple along the axis direction of process cartridge 30 side by side.And, rotated by process cartridge 30, make process tooth 33 be constituted each other by cutting 49.Thus, the stalk bits etc. being put to disconnected fringe process device 29 are cut off finely.The stalk bits cut off finely are fallen downwards by screen cloth 31.It is referred to as in the following description from the lower junk (mixture of grain, stalk bits, disconnected fringe etc.) of screen cloth 31 whereabouts and is sorted thing.The thing that is sorted fallen from screen cloth 31 is put to sorting unit 36.

Additionally, for attracting being processed the dust in small, broken bits etc. that device 29 etc. produces by disconnected fringe and to attraction fan (discharger) the 51(Fig. 6 discharged outside machine) downstream that processes device 29 on paddy stalk conveying direction with disconnected fringe is disposed adjacently.

Hereinafter, about sorting unit 36, illustrate with reference to Fig. 6.

Sorting unit 36 is configured in thrashing cylinder 16 and the lower section of disconnected fringe process device 29.As shown in Figure 6, sorting unit 36 has swing sorting portion 37 and wind sorting portion 38.

Swing sorting portion 37 to be configured in disconnected fringe and process device 29(and thrashing cylinder 16) immediately below.This swing sorting portion 37 has entry table 57, glume-shell screen 39 and separation member 73.It addition, swing sorting portion 37 there is the swing driving mechanism omitting diagram making entry table 57, glume-shell screen 39 and separation member 73 swing along device fore-and-aft direction (left and right directions of Fig. 6).

Entry table 57 is configured in the position compared with glume-shell screen 39 by upstream side on paddy stalk conveying direction, and is configured in the position more slightly higher than glume-shell screen 39.Entry table 57 is plate-shaped member, with respect to the horizontal plane slightly configures obliquely in the mode of downstream (right side of Fig. 6, the device rear) step-down of paddy stalk conveying direction.

Fringe of autotomying processes the thing that is sorted of device 29 and falls on entry table 57 or glume-shell screen 39.By this entry table 57 of wobble drive, fall that entry table 57 being sorted thing, carried to the downstream (device rear) of paddy stalk conveying direction by the inclination of this entry table 57, and fall glume-shell screen 39 from the end of downstream side of this entry table 57.

Glume-shell screen 39 is to configure multiple by multiple grain husk shell fins 40 of the substantially left and right directions crossbearer along device side by side along device fore-and-aft direction.Multiple grain husk shell fins 40 are spaced from each other suitable compartment of terrain configuration.

By making glume-shell screen 39 swing, the weight of the grain etc. being sorted in thing on this glume-shell screen 39 and little be sorted thing by falling following between grain husk shell fin 40.On the other hand, the light and big thing that is sorted of stalk bits etc. is intercepted by grain husk shell fin 40 and stays.Like this, it is possible to carry out being sorted the ragging of thing by glume-shell screen.It addition, each grain husk shell fin 40 is configured in the way of diagonally forward side by its upper surface.Thus, by making glume-shell screen 39 swing along device fore-and-aft direction, the stalk bits etc. intercepted by grain husk shell fin 40 are increasingly towards device rear (right side of Fig. 6) conveying.

Additionally, about separation member 73, explained below.

Hereinafter, illustrate about wind sorting portion 38.This wind sorting portion 38 has selecting crude drugs with winnower fan 41 and grain sieve 42.Wind sorting portion 38 is configured in the lower section swinging sorting portion 37.

Grain sieve 42 is made up of cancellous stamping parts or reel wire, and is configured in the lower section of glume-shell screen 39.It addition, in the lower section of grain sieve 42, be configured with the conveyer device 43 constituted as helix transporting device.By the ragging of described glume-shell screen 39, the weight and the little thing (grain etc.) that is sorted that fall from this glume-shell screen 39 are fallen grain sieve 42.

Selecting crude drugs with winnower fan 41 is configured to be created towards the sorting wind in downstream on paddy stalk conveying direction, makes this sorting wind blow to grain sieve 42 from downside.

In above structure, the sorting wind that selecting crude drugs with winnower fan 41 produces is sorted thing on grain sieve 42 to falling.And, regardless of whether have heavy object that this sorting wind all generally perpendicularly falls and grain to be referred to as single treatment thing.Single treatment thing is imported into a conveyer device 43, and the object that proportion in addition is little is blown towards paddy stalk conveyance direction downstream side to fly.

The single treatment thing (grain) being imported into a conveyer device 43 is transferred by this conveyer device 43, and is stored in the grain collecting box such as omitting diagram.By with upper type, it is possible to sort from being sorted thing and take out grain.

Below the end of downstream side of glume-shell screen 39 and grain sieve 42, it is configured with the second-pumping device 44 constituted as helix transporting device.

Stay the disconnected fringe on glume-shell screen 39, stalk bits etc. to be carried by the downstream towards paddy stalk conveying direction by the reciprocally swinging of this glume-shell screen 39, and fall second-pumping device 44.It addition, the sorting wind by selecting crude drugs with winnower fan 41 in the treated object fallen on grain sieve 42 is also fallen on second-pumping device 44 by blowing disconnected fringe, the stalk bits etc. that fly.Wind sorting portion 38 has Air Blast fan 45, and it makes to be sorted thing towards conveyance direction downstream side wind upwards to falling on second-pumping device 44.

Band disconnected fringe kernelly being sorted in thing falling second-pumping device 44 etc. is heavier, therefore regardless of whether there is the wind of Air Blast fan 45 all fall and be imported into second-pumping device 44.On the other hand, blown by the wind of Air Blast fan 45 without the stalk bits etc. of grain and flown, and by attracting fan 51 to be discharged to outside device.

Have with disconnected fringe kernelly etc. and implement reprocessing and take out the leeway of grain, therefore there is recovery value.The object becoming the object of reprocessing like this is called after-treatment thing.The after-treatment thing being sorted and being imported into second-pumping device 44 by wind sorting portion 38 is transferred by this second-pumping device 44, and is fed into the end of secondary reduction conveyer device (secondary reduction mechanism) 46.

Secondary reduction conveyer device 46 is the helix transporting device along roughly vertical direction configuration, is transported to by described after-treatment thing and processes with disconnected fringe compared with device 29 by the top.The after-treatment thing being transferred by secondary reduction conveyer device 46 is released and is put into disconnected fringe from the discharge port 47 of this secondary reduction conveyer device 46 and processes device 29.By above structure, it is possible to process the device 29 after-treatment thing to being sorted device 36 sorting by disconnected fringe and reprocess.

Hereinafter, the distinctive structure about present embodiment illustrates.

As it has been described above, in conventional sheller unit, there is disconnected fringe and process the situation that the treated object in device flies out to thrashing cylinder side because of the energy of the rotation of process cartridge.Especially, the sheller unit 1 of present embodiment is the structure making process cartridge rotate to the direction identical with the thrashing cylinder 16 of upper threshing type, therefore there is the situation that treated object easily flies out to thrashing cylinder 16 from the terminal of screen cloth 31.

Therefore, the sheller unit 1 of present embodiment is the structure being provided with dividing plate 34 between thrashing cylinder 16 and process cartridge 30.

This dividing plate 34 is made up of the metallic plate of atresia, and treated object can not pass through this dividing plate.As it is shown on figure 3, when observing from the direction orthogonal with the axis 32 of process cartridge 30, dividing plate 34 is configured to block the straight line axis 17 of thrashing cylinder 16 and the axis 32 of process cartridge 30 linked.It addition, as shown in Figure 4, dividing plate 34 is arranged on the whole length-over in axis 17 direction of at least thrashing cylinder 16.And, as it is shown on figure 3, the bottom of dividing plate 34 close to screen cloth 31 terminal (end in the downstream in the direction of rotation of process cartridge 30) configure.

Above, in the way of between partial closure's thrashing cylinder 16 and process cartridge 30, configure dividing plate 34, therefore, it is possible to prevent the treated object broken in fringe process device 29 from flying out to thrashing cylinder 16 side because of the energy of the rotation of process cartridge 30.Thereby, it is possible to improve disconnected fringe to process the treatment effeciency of device 29.

It addition, in the present embodiment, as it is shown on figure 3, the upper end of dividing plate 34 is set at the position higher than the upper end of the rotational trajectory of the front end processing tooth 33.Like this, the upper end of dividing plate 34 being arranged on the position higher than processing tooth 33, therefore the treated object in disconnected fringe process device 29 is difficult to fly out to thrashing cylinder 16 side above leap dividing plate 34.

It addition, the face towards process cartridge 30 side of dividing plate 34 at least some of obliquely downward.Like this, by least some of of dividing plate 34 is configured obliquely relative to plumb line, it is possible to the treated object that disconnected fringe processes in device 29 that advantageously prevents by " agnail " and fly out to thrashing cylinder 16 side.

The lower end of dividing plate 34 close to screen cloth 31 terminal configure.It addition, as it has been described above, be formed with cutting 49(in the terminal of screen cloth 31 therefore, it is possible to configure cutting 49 near the bottom of dividing plate 34).By this cutting 49, treated object is carried out cut-out process, therefore in the part of this cutting 49, produce stalk bits in small, broken bits.The stalk bits produced like this easily disperse because processing the energy of the rotation of tooth 33.Dividing plate 34 is arranged in the direction of rotation downstream of process cartridge 30 by the sheller unit 1 of present embodiment from cutting 49, even if therefore producing stalk bits in small, broken bits by cutting 49 and dispersing, it is also possible to prevent them from dispersing to thrashing cylinder 16 side.

Then, the first treated object guided plate (the first guide portion) 35 having about the sheller unit of present embodiment illustrates.

As it has been described above, the treated object produced by thrashing cylinder 16 is released towards the space 53 formed above thrashing cylinder 16 by the energy of the rotation of thrashing cylinder 16.Now, the whole treated object produced by thrashing cylinder 16 is put into disconnected fringe and processes device 29, but when the treated object being released to space 53 does not disperse along track flight by the phase of giving, this treated object is not put into disconnected fringe and processes device 29, there is the situation that the efficiency of sheller unit 1 entirety reduces.

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 local, space between thrashing cylinder 16 and process cartridge 30 is blocked.Its result, the entrance leading to disconnected fringe process device 29 becomes narrow, and treated object is difficult to enter disconnected fringe and processes device 29.

Therefore, the sheller unit 1 of present embodiment is provided with the first treated object guided plate 35 that the treated object produced by thrashing cylinder 16 is directed to the process cartridge 30 that disconnected fringe processes device 29.

Hereinafter, it is described in detail.Additionally, in the following description, during referred to as " upstream side ", " downstream ", the upstream side in the direction of rotation of thrashing cylinder 16 and downstream are referred to.

This first treated object guided plate 35 is metal plate-shaped member, is shaped generally as oblong-shaped as illustrated in fig. 7.As shown in Figure 4, the first treated object guided plate 35 is configured to its length direction and configures along axis 17 direction of thrashing cylinder 16 and can in the face of the total length in axis 17 direction of thrashing cylinder 16.

As it is shown on figure 3, the first treated object guided plate 35 is configured in downstream compared with the end of downstream side 27a of top board 27.Therefore, it can be said that this first treated object guided plate 35 is configured in downstream compared with the starting point away from portion (end of the upstream side of the second top board 52) formed above thrashing cylinder 16.It addition, this first treated object guided plate 35 is configured in the position of the treated object collision released from thrashing cylinder 16 to space 53.Therefore, thrashing cylinder 16 treated object produced is once because the energy of the rotation of this thrashing cylinder 16 is released in space 53, collide with the first treated object guided plate 35 afterwards.

First treated object guided plate 35 is configured in compared with process cartridge 30 by upstream side and above this process cartridge 30.And, in the first treated object guided plate 35, configuring thrashing cylinder 16 side facing to obliquely downward.Therefore, the lower surface (face obliquely downward) of treated object and the first treated object guided plate 35 released from thrashing cylinder 16 collides, and to the bottom of this first treated object guided plate 35 towards direction (obliquely downward) directed.

First treated object guided plate 35 by towards the face of thrashing cylinder 16 side (lower surface) by position by the top compared with the upper end of dividing plate 34 in the way of be configured.Owing to the first treated object guided plate 35 configures like this, so can reliably by the top of dividing plate 34 by the treated object that the lower surface of this first treated object guided plate 35 is directed.Thereby, it is possible to processed being directed to disconnected fringe from thrashing cylinder 16 to the treated object that space 53 releases in device 29 by the first treated object guided plate 35.

It addition, close between the upper end of the first treated object guided plate 35 and the end face of threshing chamber 15 and seamlessly constitute.More particularly, it is closed plate 55 between upper end and the end face of threshing chamber 15 of the first treated object guided plate 35 to close.Thus, owing to treated object will not streak the top of the first treated object guided plate 35, it is possible to reliably guide treated object by the first treated object guided plate 35.

Additionally, (omitting diagram) is fixed by screw in the upper end of the first treated object guided plate 35 is fixed on the lower end of described closing plate 55.Like this, the shell split ground of the first treated object guided plate 35 of present embodiment and threshing chamber 15 is constituted, and is threadably secured and is fixed.Therefore, this first treated object guided plate 35 can dismount by releasing the fastening of described screw.That is, because of the treated object frequent impact of grain etc., the first treated object guided plate 35 is the parts of easily abrasion.Therefore, make as described above and can dismount, it is possible to change worn out first treated object guided plate 35.Additionally, in the present embodiment, the lower end of the first treated object guided plate 35 is not fixed especially, is freely.

It addition, in the first treated object guided plate 35, its lower surface is provided with multiple adjustment plate 56 on (face towards thrashing cylinder 16 side).This adjustment plate 56 is made up of the metal plate-shaped member bent with approximate right angle as illustrated in fig. 7, from being protrusively provided towards the direction being substantially orthogonal towards thrashing cylinder 16 side of the first treated object guided plate 35.

As shown in the section plan of Fig. 4, multiple adjustment plate 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, each adjustment plate 56 configures obliquely relative to the direction parallel with the axis 32 of process cartridge 30.

In above structure, the treated object flown out from thrashing cylinder 16, when colliding with the first treated object guided plate 35, is imported to being processed device 29 to disconnected fringe while directed relative to the direction that the axis direction of process cartridge 30 tilts by adjustment plate 56.Like this, guide treated object by the adjustment plate 56 configured obliquely, thereby, it is possible to make this treated object disperse on the axis direction of process cartridge 30.Thus, it is prevented that treated object is intensively supplied to the ad-hoc location of process cartridge 30, it is possible to adjust the axial distribution of the treated object of process cartridge 30 supply equably.Therefore, it is possible to effectively utilize disconnected fringe on the axis direction of process cartridge 30 to process device 29.

As it has been described above, the sheller unit 1 of present embodiment has thrashing cylinder 16, process cartridge the 30, first treated object guided plate 35 and dividing plate 34.Thrashing cylinder 16 to be set to centered by approximate horizontal axis 17 rotating upper threshing type, and has multiple threshing tooth 22 on the outer periphery.Process cartridge 30 by almost parallel by the axis 17 of thrashing cylinder 16 and be set in the axis 32 of the position lower than axis 17 centered by rotate, and there is multiple process tooth 33 on the outer periphery.The treated object produced by thrashing cylinder 16 is guided towards process cartridge 30 by the first treated object guided plate 35 by following table.Dividing plate 34 is configured between thrashing cylinder 16 and process cartridge 30.The upper end of dividing plate 34 is set at the position higher than the upper end of the rotational trajectory of the front end processing tooth 33.First treated object guided plate 35 by described lower surface by compared with the upper end of dividing plate 34 by the top in the way of be configured.

Like this, arranging dividing plate 34 between thrashing cylinder 16 and process cartridge 30, making the upper end of this dividing plate 34 is the position higher than processing tooth 33, therefore, it is possible to stop treated object to fly out from process cartridge 30 to thrashing cylinder 16.Further, since adopt the structure being guided treated object by the first treated object guided plate 35, it is possible to this treated object is put into process cartridge 30 swimmingly.By above structure, it is possible to reliably located the treated object that reason thrashing cylinder 16 produces by process cartridge 30, therefore, it is possible to improve the efficiency that sheller unit is overall.

Then, the second treated object guided plate (the second guide portion) 63 having about the sheller unit 1 of present embodiment illustrates.

As already described, the sheller unit 1 of present embodiment is to be guided by the lower surface of the first treated object guided plate 35 to direct it to disconnected fringe process the structure of device 29 from the treated object of thrashing cylinder 16 releasing.But, it practice, the treated object produced by thrashing cylinder 16 be not all guided by the first treated object guided plate 35 and draw enter disconnected fringe process device 29 desirable track fly.Such as, shown in the accompanying drawing labelling 61 of Fig. 3, when the collision of parts beyond treated object and the first treated object guided plate 35, this treated object is to the resilience of unforeseen direction.When treated object flies with being not drawn into desirable track, it is possible to this treated object fails to enter disconnected fringe and processes device 29, and by falling between process cartridge 30 and thrashing cylinder 16.

Therefore, the sheller unit 1 of present embodiment is provided with and is caught by the treated object upper surface produced by thrashing cylinder 16 and process, to disconnected fringe, the second treated object guided plate 63 that device 29 guides.

This second treated object guided plate 63 is configured between thrashing cylinder 16 and process cartridge 30.More correctly, as it is shown on figure 3, when observing from axis 32 direction of process cartridge 30, plumb line at the center by the axis 17 of thrashing cylinder 16 and by configuring the second treated object guided plate 63 between the plumb line at the center of the axis 32 of process cartridge 30.Second treated object guided plate 63 is configured in compared with process cartridge 30 by upstream side in the direction of rotation of thrashing cylinder 16.It addition, the second treated object 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, owing to the second treated object guided plate 63 is arranged between thrashing cylinder 16 and process cartridge 30, it is possible to utilize the upper surface of the second treated object guided plate 63 to catch the treated object wanted by falling between thrashing cylinder 16 and process cartridge 30.

In the present embodiment, the second treated object guided plate 63 is a metallic plate, and its upper surface is formed substantially smoothly and constitutes guide surface 63a.As it is shown on figure 3, when observing from axis 32 direction of process cartridge 30, the guide surface 63a of the second treated object guided plate 63 configures with being inclined relative to horizontal.More particularly, configure in the way of the end of process cartridge 30 side of guide surface 63a is lower than the end of thrashing cylinder 16 side.Like this, guide surface 63a configures obliquely in the way of the step-down of process cartridge 30 side, and the treated object therefore caught by guide surface 63a is guided naturally towards process cartridge 30.

It addition, as it is shown on figure 3, configure in the way of the end of process cartridge 30 side of guide surface 63a is connected with the upper end of dividing plate 34.Owing to guide surface 63a configures by this way, so the top of dividing plate 34 can be passed through by treated object directed for this guide surface 63a.It is as a result, it is possible to process the treated object caught by this guide surface 63a in device 29 to disconnected fringe and import.

As it has been described above, the sheller unit 1 of present embodiment makes the second treated object guided plate 63 caught by the treated object upper surface produced by thrashing cylinder 16 and guide to process cartridge 30 be arranged between thrashing cylinder 16 and process cartridge 30.

By arranging the second treated object guided plate 63 like this, it is possible to prevent untreated treated object by falling between thrashing cylinder 16 and process cartridge 30, and this treated object can be caught and guide to process cartridge 30.

Then, the spiral guide member 65 having about the disconnected fringe process device 29 of present embodiment illustrates.Treated object in disconnected fringe process device 29 is carried by this spiral guide member 65 along axis 32 direction of process cartridge 30.

As it is shown on 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.It addition, the disconnected fringe of present embodiment processes device 29 has multiple described spiral guide member 65.Multiple spiral guide members 65 configure in parallel to each other, and configure side by side in the spaced up suitable compartment of terrain, side parallel with the axis 32 of process cartridge 30.

As it is shown on figure 3, when observing from axis 32 direction of process cartridge 30, the contour shape of the end face of process cartridge 30 side of spiral guide member 65 is shaped generally as arc-shaped along the rotational trajectory of the front end processing tooth 33.Additionally, spiral guide member 65 is configured in compared with the rotational trajectory of the front end processing tooth 33 in the outer part.Thus, spiral guide member 65 is not interfered with the process tooth 33 rotated.

And, as shown in Fig. 4 and Fig. 9, the spiral guide member 65 of tabular configures obliquely relative to the direction (device fore-and-aft direction) parallel with the axis 32 of process cartridge 30.

Spiral guide member 65 arrangement as above, it can be said that the end face relative with process cartridge 30 of each spiral guide member 65 is approximately along the configuration spirally centered by the axis 32 of this process cartridge 30.Additionally, in the present embodiment, spiral guide member 65 configures in the mode along the spiral of the left hand direction centered by the axis 32 of process cartridge 30.

Spiral guide member 65 role arrangement as above is illustrated.

The treated object that disconnected fringe processes in device 29 along with the process cartridge 30 rotated and processes tooth 33, processes in device 29 at disconnected fringe and rotates around axis 32.Like this around the treated object of axis 32 rotation by time between process cartridge 30 and dividing plate 34, directed by spiral guide member 65, and move along this spiral guide member 65.Spiral guide member 65 is along the configuration spirally centered by the axis 32 of process cartridge 30, and the treated object therefore guided by this spiral guide member 65 moves along this spiral.

As it has been described above, spiral guide member 65 configures along left-handed spiral.It addition, the disconnected fringe in present embodiment processes in device 29, constitute rotatably (counterclockwise) to the left as it is shown on figure 3, process cartridge 30 is observed from device face side (front side).Therefore, the treated object guided by spiral guide member 65 processes in device 29 at disconnected fringe and is carried towards device rear (downstream on paddy stalk conveying direction).

Like this, it is possible to the treated object in disconnected fringe process device 29 is carried along the axis 32 of process cartridge 30, therefore, it is possible to make the treated object that disconnected fringe processes in device 29 disperse on axis 32 direction of process cartridge 30.Such as, the amount being put into the treated object that disconnected fringe processes device 29 from thrashing cylinder 16 is more many closer to (upstream side on paddy stalk conveying direction) on front side of device, is put into the amount of the treated object in (downstream on paddy stalk conveying direction) on rear side of device less.Therefore, the treated object processed in device 29 by disconnected fringe as described above by spiral guide member 65 is carried towards device rear, thereby, it is possible to make this treated object disperse on the axis direction of process cartridge 30.Thereby, it is possible to the whole total length at process cartridge 30 effectively utilizes disconnected fringe to process device 29 equably, therefore, it is possible to improve this disconnected fringe to process the treatment effeciency of device 29.

Disconnected fringe processes the treated object in device 29 during being carried towards device rear, the effect processing tooth 33 that can be rotated in multiple times, and the therefore grain coverlet granulation contained by this treated object, and stalk bits is chopped into.Grain or become stalk in small, broken bits bits and drop to sorting unit 36 by screen cloth 31.On the other hand, finally the big dust of not being chopped into arrives disconnected fringe and processes the rearward end (end in the downstream on paddy stalk conveying direction) of device 29.

As shown in Fig. 4, Fig. 8 and Fig. 9, the rearward end at process cartridge 30 is provided with the blade 68 of dishing out rotated integratedly with this process cartridge 30.This blade 68 of dishing out is the parts of the tabular that the axis 32 with process cartridge 30 configures abreast, is provided with multiple in the way of highlighting from the surrounding of process cartridge 30.It addition, be not provided with screen cloth 31 in this part dishing out blade 68.It is to say, dish out, the lower section of blade 68 is open.

As shown in Figure 6, at the separation member 73 being arranged below swing sorting portion 37 of blade 68 of dishing out.As shown in Figure 4, separation member 73 is by substantial amounts of thread-like member (tinsel) 69 structure that spaced up suitable compartment of terrain is arranged side by side abreast in device right and left.As shown in Figure 6, separation member 73 is configured in the top of glume-shell screen 39.

In above structure, process, at disconnected fringe, the treated object (big dust etc.) being transported to rearward end in device 29 and be spilled over by the lower section that is rotated towards of blade 68 of dishing out, and fall on separation member 73.Now, big dust etc. is stuck in thread-like member 69 and stays on separation member 73.When grain is mixed into the treated object fallen on separation member 73, this grain is by falling on glume-shell screen 39 between thread-like member 69.Eventually fall in the treated object on separation member 73 (big dust etc.) to be attracted fan 51 and attract, and be discharged to outside machine.

Additionally, the treated object from the rearward end whereabouts that disconnected fringe processes device 29 becomes, by the energy of the rotation of blade 68 of dishing out, the state expanded along device left and right directions.Therefore, the treated object of the big bulk that sticks together will not be fallen on separation member 73.Thereby, it is possible to prevent grain to be mixed in the dust of the bulk that sticks together be discharged to the outer such loss of machine indissociably.

As it has been described above, in the sheller unit 1 of present embodiment, disconnected fringe processes device 29 and has the spiral guide member 65 being arranged as opposed to the side face of process cartridge 30 and configuring approximately along the spiral centered by the axle of described process cartridge 30.

By arranging spiral guide member 65 like this, it is possible to disconnected fringe to be processed the axial conveying along process cartridge 30 of the treated object in device 29.Process in device 29 thereby, it is possible to prevent big dust to be trapped in disconnected fringe, and the treatment effeciency of this disconnected fringe process device 29 can be improved.

Then, in the sheller unit of present embodiment, illustrate about the structure processing after-treatment thing by disconnected fringe process device 29.The sheller unit 1 of present embodiment is provided with the secondary boot path 48 putting into the fringe process device 29 that breaks along the direction parallel with the axis 32 of process cartridge 30 while being guided by the after-treatment thing released from the discharge port 47 of secondary reduction conveyer device 46.

Hereinafter, it is described in detail.As shown in Fig. 3, Fig. 4 and Figure 10, secondary boot path 48 constitutes (additionally, in the diagram, for representing the inside of secondary boot path 48, eliminate top 72) as the space surrounded by bottom surface 70, sidewall 71 and top 72.As shown in Fig. 4 and Figure 10, at the discharge port 47 of one end connecting secondary reduction conveyer device 46 of the length direction of secondary boot path 48.By this structure, the after-treatment thing being transferred by secondary reduction conveyer device 46 is released in secondary boot path 48.

As shown in Figure 10, the length direction of secondary boot path 48 configures with being inclined relative to horizontal.Described discharge port 47 is connected the end of a high side of the secondary boot path 48 configured obliquely.Therefore, the after-treatment thing released 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, during top view, the length direction of secondary boot path 48 configures approximately along axis 32 ground of process cartridge 30.Therefore, it is directed approximately along the axis 32 of process cartridge 30 that the after-treatment thing released from discharge port 47 passes through secondary boot path 48.

As it is shown on figure 3, on the cross section orthogonal with the axis 32 of process cartridge 30, the end of the side of the bottom surface 70 of secondary boot path 48 is closed by sidewall 71, the open-ended of opposite side.Additionally, in the following description, the end of the side of the opening of bottom surface 70 is called open end, the end of the side closed by sidewall 71 is called blind end.As it is shown on figure 3, on the cross section orthogonal with the axis 32 of process cartridge 30, bottom surface 70 configures in the way of open end is lower than blind end with being inclined relative to horizontal.In above structure, after-treatment thing directed in secondary boot path 48 can drop to lower section from the open end of bottom surface 70.

As it is shown on figure 3, secondary boot path 48 is configured in processes, than disconnected fringe, the position that device 29 is high.And, on the cross section (Fig. 3) orthogonal with 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 process device 29.It addition, described bottom surface 70 configures in the way of process cartridge 30 by its open end.In above structure, the after-treatment thing fallen from the open end of bottom surface 70 is processed in device 29 to disconnected fringe to be put into.

As shown in Figure 4, during top view, secondary boot path 48 by along with away from discharge port 47, bottom surface 70 narrowed width in the way of constituted.It addition, as it has been described above, bottom surface 70 configures obliquely in the way of open end is lower than blind end.Therefore, directed in secondary boot path 48 after-treatment thing falls from the open end of bottom surface 70 sooner or later.By above structure, the after-treatment thing released from discharge port 47 direction of axis 32 along process cartridge 30 secondary boot path 48 in is directed, falls from the open sides end of bottom surface 70 simultaneously and is processed input in device 29 to disconnected fringe.

Being various from the speed of the after-treatment thing of discharge port 47 releasing or direction, therefore some after-treatment thing falls the position close to discharge port 47, and some after-treatment thing falls the position away from discharge port 47.Therefore, after-treatment thing is moderately disperseed on axis 32 direction of process cartridge 30 by the position put into disconnected fringe process device 29.

Like this, secondary boot path 48 is set by the axis 32 approximately along process cartridge 30, it is possible to make the after-treatment thing released from the discharge port 47 of secondary reduction conveyer device 46, on axis 32 direction of process cartridge 30, scattered basis process device 29 to disconnected fringe and supply.Thereby, it is possible to prevent after-treatment thing to be intensively supplied to disconnected fringe process the specific position of device 29, it is possible to effectively utilize this disconnected fringe to process device 29 in whole total length.

Additionally, in the present embodiment, as shown in Figure 4, the discharge port 47 of secondary reduction conveyer device 46 by the conveying direction of paddy stalk 14 downstream side release in the way of after-treatment thing towards upstream side and to be constituted.It addition, the bottom surface 70 of secondary boot path 48 is on the conveying direction of paddy stalk 14, its width becomes narrow gradually along with lateral upstream side downstream.And, this bottom surface 70 is formed without the upstream-side-end (that is, bottom surface 70 disconnects) of process cartridge 30 in midway on the conveying direction of paddy stalk 14.By above structure, after-treatment thing is supplied to disconnected fringe and processes the upstream side of device 29 by secondary boot path 48 hardly.

It addition, in the sheller unit 1 of present embodiment, as it is shown on figure 3, when observing from axis 32 direction of process cartridge 30, the discharge port 47 of secondary reduction conveyer device 46 is positioned at the opposition side of thrashing cylinder 16 across the first treated object guided plate 35.That is, between discharge port 47 and thrashing cylinder 16, described first treated object guided plate 35 it is configured with.Thus, even if the after-treatment thing from discharge port 47 releasing disperses towards thrashing cylinder 16 side, owing to this after-treatment thing and the first treated object guided plate 35 collide, therefore, it is possible to prevent this after-treatment thing from flying out to thrashing cylinder 16 side.

Additionally, in the present embodiment, on the upper surface (face towards discharge port 47 side) of the first treated object guided plate 35, multiple after-treatment thing adjustment plate 74 is installed.This after-treatment thing adjustment plate 74 is protrusively provided from the upper surface of the first treated object guided plate 35 along the direction being substantially orthogonal.It addition, multiple after-treatment thing adjustment plate 74 configure side by side along the direction parallel with the axis 32 of process cartridge 30.And, each after-treatment thing adjustment plate 74 configures obliquely relative to the direction parallel with the axis 32 of process cartridge 30.

This after-treatment thing adjustment plate 74 is obtained in that the effect same with aforesaid adjustment plate 56.That is, guided to the direction tilted relative to the axis direction of process cartridge 30 by after-treatment thing adjustment plate 74 with the after-treatment thing of the first treated object guided plate 35 collision, processed device 29 to disconnected fringe simultaneously and import.Like this, guide after-treatment thing by after-treatment thing adjustment plate 74, thus enable that the position that this after-treatment thing puts into disconnected fringe process device 29 disperses on the direction parallel with the axis 32 of process cartridge 30.Thereby, it is possible to more effectively utilize disconnected fringe to process device 29 on axis 32 direction of process cartridge 30.

As it has been described above, the sheller unit 1 of present embodiment has sorting unit 36, secondary reduction conveyer device 46 and secondary boot path 48.The treated object processed by disconnected fringe process device 29 is at least sorted into the single treatment thing that need not reprocess and needs the after-treatment thing of reprocessing by sorting unit 36.Secondary reduction conveyer device 46 is transported to disconnected fringe processes the top of device 29 by being sorted the after-treatment thing that device 36 sorts.The after-treatment thing released from the discharge port of secondary reduction conveyer device 46 is put into disconnected fringe process device 29 by secondary boot path 48 while the direction guiding of the axis 32 of process cartridge 30.

By arranging secondary boot path 48 like this, it is possible to make the after-treatment thing released from secondary reduction conveyer device 46 disperse and process device 29 to disconnected fringe to put into along the direction parallel with the axis 32 of process cartridge 30.Thus, owing to disconnected fringe can be utilized vertically equably to process device 29, it is possible to improve this disconnected fringe to process the treatment effeciency of device 29.

It is explained above the preferred embodiment of the present invention, but said structure can such as change on the following stated ground.

The sheller unit 1 of the present invention can be applicable to the various sheller units such as the built-in sheller unit of the built-in sheller unit of fixing sheller unit, harvester, united reaper.

Lower surface for the first treated object guided plate 35 is illustrated by position by the top compared with the upper end of dividing plate 34, but the first treated object guided plate 35 not necessarily must be arranged in the surface of dividing plate 34.That is, even if the first treated object guided plate 35 is configured in the position of surface of deviation dividing plate 34, as long as the elongated surfaces of its lower surface is arranged in compared with the upper end of dividing plate 34 position by the top.By configuring the first treated object guided plate 35 like this, it is possible to guided by the first treated object guided plate 35 in the way of the treated object produced by thrashing cylinder 16 passes through the top of dividing plate 34.

Adjustment plate 56 can set as suitably desired relative to the angle of the axis 32 of process cartridge 30.It addition, the angle of each adjustment plate 56 can also be different.It addition, adjustment plate 56 can also configure orthogonally relative to axis 32 direction of process cartridge 30.This adjustment plate 56 can certainly be omitted.

Top board 27 and the second top board 52 can also as being integrally formed.In a word, as long as being formed at top from what the rotational trajectory of the front end of threshing tooth 22 was gradually distance from away from portion, its structure is not particularly limited.

Dividing plate 34 can also be omitted.

Close plate 55 alternatively, it is also possible to omit, the upper end of the first treated object guided plate 35 is directly fixed relative to the end face of threshing chamber 15.In this case, it may also be said to can make to close between upper end and the end face of the first treated object guided plate 35.

In the above-described embodiment, spiral guide member 65 have employed the parts of tabular, but is not limited to this.As long as spiral guide member 65 can spirally guide disconnected fringe to process the treated object in device 29, its shape etc. is not particularly limited.Additionally, in the above-described embodiment, owing to spiral guide member 65 adopts flat parts, so strictly, this spiral guide member 65 is not strictly along configuring spirally.But, spiral guide member 65 need not strictly along configuring spirally.As long as spiral guide member 65 configures approximately along the tangent line of the spiral centered by the axis 32 of process cartridge 30, thereby, it is possible to the effect that the treated object obtaining fully processing in device 29 by disconnected fringe is carried along the axis direction of process cartridge 30.

In the above-described embodiment, being arranged side by side along the axis direction of process cartridge 30 by multiple spiral guide members 65, but be not limited to this, spiral guide member 65 can also only have one.

Illustrating such as above-mentioned embodiment, the treated object that disconnected fringe is preferably processed in device 29 by spiral guide member 65 is carried to device rear.It is however not limited to this, it is also possible to the treated object processed by disconnected fringe in device 29 is carried to device front, and makes its leading section processing device 29 from this disconnected fringe fall.

Separation member 73 is not limited to the structure of above-mentioned embodiment, as long as big dust the parts making grain pass through can be caught, it is also possible to be such as reel wire etc..

The structure of secondary boot path 48 is an example, is not limited to said structure.As long as the structure of the after-treatment thing released from secondary reduction conveyer device 46 can be guided along the direction parallel with the axis 32 of process cartridge 30, the shape etc. of secondary boot path 48 is not particularly limited.

Secondary reduction mechanism is conveying worm formula, but is not limited to this, it is possible to utilize suitable conveying mechanism.

The angle of after-treatment thing adjustment plate 74 can suitably set as required.It addition, the angle of multiple after-treatment thing adjustment plate 74 can also be different.It addition, after-treatment thing adjustment plate 74 can also configure orthogonally relative to the direction parallel with the axis 32 of process cartridge 30.Certainly it also is able to omit this after-treatment thing adjustment plate 74.
