(upper wall, wind direction guide member)
As shown in Figure 6, the air outlet 65 of winnower winnowing machine housing 17 above upper wall 67 and below lower wall 68 between opening, these upper walls 67 and lower wall 68 up and down in the middle of be provided with wind direction guide member 66.Like this, air outlet 65 is divided into upside wind path 74 between wind direction guide member 66 and upper wall 67 and the downside wind path 75 between wind direction guide member 66 and lower wall 68.Upper wall 67 and lower wall 68 form tabular in illustrated example, but are not limited thereto.
As shown in Fig. 6, Figure 13, there is 70 vertical section, summit below wind direction guide member 66 is formed in and there is the shape of upside-down triangle shape.Thus, at the upper surface 69 of the wind direction guide member 66 of illustrated example, by the upper wall 67 with winnower winnowing machine housing 17, roughly the same inclination tabular surface forms, and the lower surface of wind direction guide member 66 is formed by the flexure plane with lower forequarter inclined plane 71 and inclined plane, downside rear portion 72.If wind direction guide member 66 has such shape, the wind of sending from upside wind path 74 flows to diffusely and shakes screening frame 20 downwards hardly along the upper surface of wind direction guide member 66, flows to the scope in the more downstream of shaking screening frame 20 when the wind of sending from downside wind path 75 spreads upward along the inclined plane, downside rear portion 72 of wind direction guide member 66.
Wind direction guide member 66 is configured to, and take with the turning cylinder 66x of the level of air supply direction quadrature is center of rotation, and upper surface 69 and lower surface 71,72 towards the air supply direction downstream, become oblique upper to angular range in freely rotate.In addition, the turning cylinder 66x of wind direction guide member 66 is positioned in the middle of the air supply direction of wind direction guide member, take the upstream side of turning cylinder 66x and downstream to rotate as upper and lower mode.Its both ends axle of the turning cylinder 66x of wind direction guide member 66 is bearing on screening 18 two side, chamber 18S.And be configured to, in the rotation by wind direction guide member 66, make the inclination angle relative with the horizontal plane of wind direction guide member 66 (being designated hereinafter simply as inclination angle or inclination attitude) while being increased to maximum, the end of winnower winnowing machine 16 sides of wind direction guide member 66 and the lower wall 68 of air outlet 65 near to or in contact with.
In addition, upper wall 67 also is configured to, and take with the horizontal rotating shaft 67x of air supply direction quadrature is center of rotation, and at lower surface, towards air supply direction, become oblique upper to angular range in, to the direction identical with wind direction guide member 66, rotate., between the rear upper surface of the rear portion lower surface of use gangbar 88 connection upper walls 67 and wind direction guide member 66, upper wall 67 and wind direction guide member 66 are maintained to roughly certain relative posture, under this state, formation can change the link gear S of angle up and down.In addition, the turning cylinder 67x of upper wall 67 is positioned at winnower winnowing machine 16 side ends of upper wall 67 in illustrated example, but also can be positioned in the middle of air supply direction or the air supply direction end of downstream side, in a word, as long as take the downstream of upper wall 67, rotates as upper and lower mode.Its two ends of turning cylinder 67x of upper wall 67 also axle are bearing on screening 18 two side, chamber 18S.
In this structure, for the upside wind path 74 of the wind of supplying with from winnower winnowing machine 16 and the allocation proportion of downside wind path 75, by the ratio of the peristome of upside wind path 74 and downside wind path 75, determined.Therefore, the direction reduced at the opening degree of downside wind path 75, if upper wall 67 and wind direction guide member 66 rotate in identical direction interlock, the air quantity of downside wind path 75 reduces, on the contrary, if the air quantity of upside wind path 74 increases, and the wind direction of downside wind path 75 changes according to the angle of the lower surface of wind direction guide member 66, and the wind direction of upside wind path 74 changes according to the angle of the lower surface of wind direction guide member 66.On the other hand, the direction increased at the opening degree of downside wind path 75, if upper wall 67 and wind direction guide member 66 in identical direction interlock and rotate, the air quantity of downside wind path 75 increases, on the contrary, the air quantity of upside wind path 74 reduces.The wind direction of downside wind path 75 changes according to the angle of the lower surface of wind direction guide member 66, and the wind direction of upside wind path 74 changes according to the angle of the lower surface of wind direction guide member 66.Namely, can adjust wind direction and the air quantity of upside wind path 74 and downside wind path 75 simultaneously.
The member rotated so long as make two wind direction guide members 66,67 interlocks for the driving mechanism that wind direction guide member 66 and upper wall 67 rotated just can suitably be selected and be designed, both can be with the manual power source that also can use motor etc.In the example shown in Figure 13, the end of the turning cylinder 66x of wind direction guide member 66 is outstanding from the sidewall 18S of screening chamber 18, and the main leading section that shakes lever 81 is installed on this ledge, and this master shakes lever 81 and wind direction guide member 66 rotates integratedly.In addition, sidewall 18S outside in screening chamber 18 is equipped with pillar 82, on the driving shaft 83x that is equipped on motor 83 on this pillar 82, pinion 83g is installed, with fan-shaped gear 84 axles of this pinion 83g engagement, be bearing on pillar 82, the circumferential ends of one side's side of this fan-shaped gear 84 (the first eccentric position) and the main base end part that shakes lever 81 link by gangbar 85, and each linking portion links freely by pin 85p rotation.And, be configured to, be equipped with the rotary volume detecting devices 86 such as potentiometer on pillar 82, on the detection axle 86x of this rotary volume detecting device 86, the leading section that pair is shaken pillar 87 is installed, shake the amount of spin of lever 87 to detect pair, and be configured to, outstandingly be provided with pin 87p the circumferential ends (the second eccentric position) of the opposition side of fan-shaped gear 84 is upper, this pin 87p slides in the groove 87d of the length direction that shakes lever 87 along pair.In addition, than the turning cylinder 66x of wind direction guide member 66, by the position in air supply direction downstream with than the turning cylinder 67x of upper wall 67, by the position in air supply direction downstream, in screening 18Nei both sides, chamber, by gangbar 88, link respectively, each linking portion utilization pin 88p rotation links freely.
Therefore, utilize the positive and negative driving of motor 83, wind direction guide member 66 shakes the positive and negative rotation of lever 81 by fan-shaped gear 84, gangbar 85, master, and its amount of spin shakes lever 87 by rotary volume detecting device 86 detections by fan-shaped gear 84 and pair.In addition, follow the rotation of wind direction guide member 66, the upper wall 67 linked with it by gangbar 88 also links and rotates.Therefore, wind direction guide member 66 and upper wall 67 are rotated simultaneously and to equidirectional, can be adjusted to respectively the angle of regulation, it is easy that adjusting operation becomes.
Although the inclination angle (also referred to as inclination angle or inclination attitude) with respect to the horizontal plane of wind direction guide member 66 and upper wall 67 can suitably change respectively in above-mentioned scope, it (is chaffer 24 than sieve that more than half flow directions of preferably tilt angle ranges of wind direction guide member 66 and upper wall 67 being set for to the screening wind of upside wind path 74 are shaken in screening frame 20 in illustrated example.Screening net 28 also can) downstream (rear side) end is by upstream side, and from more than half flow directions of the screening wind of downside wind path 75 than sieve (chaffer 24) downstreams (rear side) end downstream.In this scope, by making the tilt angle varied of wind direction guide member 66 and upper wall 67, no matter thereby the state that the flow of handled thing is low discharge (when flow hangs down) or the state of high flow capacity (when flow is high), more suitable screening can both be carried out, the reduction of grain loss and the optimization of screening can be realized.
Particularly, as shown in figure 13, the screening wind of upside wind path 74, downside wind path 75 preferably is configured to, the inclination angle of wind direction guide member 66 is larger, the screening wind of two wind paths 74,75 all increases upstream side (front side) air quantity that the flow direction is shaken screening frame 20, and the air quantity that flows to downstream (rear side) reduces.And, more preferably be configured to, as shown in figure 14, while making the inclination angle of wind direction guide member 66 maximum, the air quantity of upside wind path 74 is more than the air quantity of downside wind path 75.And, when the inclination angle that preferably makes wind direction guide member 66 is maximum, during side-looking, the air supply direction extended line 66L of the upper surface of wind direction guide member 66 is positioned at the plate end 19C place closer to the top than a shelf 19A, increases the screening wind that flows to the upstream side (the place ahead) that shakes screening frame 20 from the plate end 19C of a shelf 19A.In addition, thus, the screening wind of carrying from winnower winnowing machine 16 blows to upside from the position of comparing by rear side at the position screening frame 20 of shaking of the below with towards reclaiming chamber 11F.
Like this, thereby shake by reduction when flow for example is low or during the low speed operation outside the screening wind reduction machine in downstream of screening frame 20, disperse, flow to the screening wind of the upstream side that shakes screening frame 20 by increase, the grain that thereby rice straw is cut off in restriction or be with branch to obstruct etc. leaks down, and can guarantee to screen in good condition.In addition, from reclaim grain that chamber 11F falls by from shaking the screening wind that screening frame 20 blows afloat situation about rearward flying up reduce, dispersing to outside in the rear end that this grain is difficult to from shaking screening frame 20, can improve the organic efficiency of grain.
Particularly, preferably at the inclination angle that makes wind direction guide member 66, increase to when above to a certain degree, for example, while being maximum, when overlooking, the suction port 45 of dust exhausting fan 43 is in the air supply direction extended line 66L of the upper surface of wind direction guide member 66 upper shed (in other words, extended line 66L and suction port 45 intersect).Thus, can enough dust exhausting fan 43 efficiency attract well the dust blown afloat forwardly, even screening wind is difficult to the structure (situation that particularly has three times such dust-exhausting port baffle plates 57 of illustrated example) to the body rear, also harmless screening capacity, can be discharged to dust outside machine effectively.
In addition, as shown in figure 15, the screening wind of upside wind path 74, downside wind path 75 preferably is configured to, the inclination angle of wind direction guide member 66 is less, the screening wind of two wind paths 74,75 all is altered to wind direction the downstream of shaking screening frame 20, reduce the air quantity of upside wind path 74, and increase the air quantity of downside wind path 75.And, more preferably make inclination angle for hour, the air quantity of downside wind path 75 is more than the air quantity of upside wind path 74.And preferably make inclination angle for hour, the air supply direction extended line 66L of the upper surface of wind direction guide member 66 be positioned at a shelf 19 plate end 19C and near, increase the screening wind of the plate end 19C that flows to a shelf 19A.Thus, can promote when the high speed operation or the high time screening wind of flow from the screening chamber thoroughly to machine, suppress also commercial weight, improve the adaptability to the high speed operation.
The variable quantity at the inclination angle of wind direction guide member 66 and upper wall 67 is identical is advisable, but also can make its difference.For example, as Figure 14, shown in Figure 15, when the inclination angle of wind direction guide member 66 turns to minimum state from maximum state, amount of spin with respect to the front end (winnower winnowing machine 16 sides) of upper wall 67, if it is large to be configured to the rotation quantitative change of front end of wind direction guide member 66, the amount of spin of the front end of upper wall 67 (winnower winnowing machine 16 sides) diminishes relatively, thereby the air quantity of harmless upside wind path 74, not only can change wind direction, but also the amount of spin that can make the front end of wind direction guide member 66 relatively becomes large, can change significantly the distribution ratio of screening wind to upside wind path 74 and downside wind path 75, and because the wind direction of two wind paths can change thereby comparatively desirable.
The upper limit at the inclination angle of wind direction guide member 66 and upper wall 67 (upper limit angle) and lower limit (lower limit angle) are fixed as suitable, but due to the suitable tilt angle ranges of wind direction guide member 66 according to crops condition and operation species and difference, therefore preferably serially or stage ground change.In addition, at variable upper limit angle and the occasion at lower limit angle, preferably the movable hand in its upper limit angle and lower limit angle is adjusted into angle arbitrarily, in addition according to crop species etc., can automatically change to the angle of predesignating, more preferably changeable both.The occasion of manually adjusting, when using combine, at predefined upper limit angle and for example, with crops condition (degree of the lodging of the number of the amount of moisture of operation, crop, the increase and decrease of handled thing amount) the not consistent occasion in lower limit angle, can at random revise.On the other hand, in the occasion automatically changed, can switch upper limit angle and lower limit angle according to crop species such as rice, wheats by being configured in advance, thereby switch simply upper limit angle and lower limit angle according to crop species, can carry out suitable screening.For example, the grain ratio rice of wheat in the handled thing amount is little, even flow is identical, in order to improve the outer efficiency of the machine of being discharged to, the upper limit at the inclination angle of wind direction guide member 66 is reduced, to improve treatment effeciency.
Figure 16 means the example of operation board of the change at upper limit angle for carrying out wind direction guide member 66 and upper wall 67 and lower limit angle, near the opening degree of regulating sieve, be provided with side by side switching rotary switch 91, with opening adjustment rotary switch 92, consistent with " rice " or " wheat " by making to switch rotary switch 91, thereby automatically change upper limit angle and the lower limit angle of wind direction guide member 66 and upper wall 67 according to each crop species, switch rotary switch if make consistent with " manually ", the upper limit angle of wind direction guide member 66 and upper wall 67 and lower limit angle are altered to the angle arbitrarily of determining according to the position of rotation of opening adjustment rotary switch 92.
Although the upper limit angle of wind direction guide member 66 and upper wall 67 and the setting at lower limit angle mechanically are advisable, but as mentioned above, in the situation that utilize the drive source of motor etc. to carry out the rotation of wind direction guide member 66 and upper wall 67, it is desirable to utilize drive to control by it and carry out.
(detecting sensor after layer)
The inclination angle of wind direction guide member 66 and upper wall 67 is fixed as suitable with the treating capacity of shaking on screening frame 20 irrelevantly.But the suitable wind direction in wind filter and air quantity are according to the handled thing amount and difference.Preference as, when flow is low or during the low speed operation, thereby the screening wind reduction machine that shakes the downstream of screening frame 20 by reduction disperses outward, thereby flowing to the screening wind restriction cut-out rice straw of the upstream side that shakes screening frame 20 or the grain of band branch stalk etc. by increase leaks down, and preferably at high speed operation or flow when high, promote screening wind from the screening chamber thoroughly to machine, suppress also commercial weight, improve the adaptability to the high speed operation.Therefore, the inclination angle of wind direction guide member 66 and upper wall 67 and handled thing amount independently in fixing situation, likely reduce screenability due to the increase and decrease of handled thing amount.
So, preferably as shown in Fig. 7, Figure 10, Figure 14, the bed thickness detecting sensor 95 of the thickness that detects the layer that shakes the handled thing on screening frame 20 is set, and control device (not shown) is set, the testing result of this control device based on this bed thickness detecting sensor 95, at the thickness of the layer of handled thing while having increased, the inclination angle of wind direction guide member 66 and upper wall 67 relative level faces is increased, at the thickness of the layer of handled thing, while having reduced, the inclination angle of wind direction guide member 66 and upper wall 67 relative level faces is reduced.Like this, even the thickness increase and decrease of the layer of handled thing also can suitably be adjusted the inclination angle of wind direction guide member 66 and upper wall 67 automatically according to the testing result of the bed thickness that shakes the handled thing on screening frame 20, obtain best grain loss and screening state.
Bed thickness detecting sensor 95 can form by using known contact or non-contact sensor.In illustrated example, be configured to as follows, end side (the after-treatment thing is stomodaeum side or front also) part in the gripper shoe 42 of after-treatment chamber 40, with the bottom of the intermediate bulkheads 11K of dust discharge process chamber introduction part 11E, by sensor strut 95S, linked, the rotary volume detecting device 96 of potentiometer etc. is installed on this sensor 95S, and to hang lower state, buoyancy aid 97 is installed on the detection axle 96x of this rotation amount detecting sensor 96, this buoyancy aid 97 contacts with the handled thing shaking movement in the handover frame section 22 of screening frame 20, in the time of along the rotation of the moving direction of handled thing, lift, its rotation amount is detected by rotary volume detecting device 96 as the bed thickness transferring handled thing mobile in frame section 22.
Like this, if adopt the structure of bottom that links the intermediate bulkheads 11K of end side (the after-treatment thing is stomodaeum side or the front also) part of gripper shoe 42 of after-treatment chamber 40 and dust discharge process chamber introduction part 11E by sensor strut 95S, avoid becoming from the after-treatment thing position of the obstacle of the discharge of the after-treatment thing of stomodaeum 43a and handover thereof also, not only can buoyancy aid 97 be set with vacant state, and the gripper shoe 42 of after-treatment chamber 40, intermediate bulkheads 11K and sensor strut 95S can connect to triangle, therefore there is advantage aspect the strengthening of frame 1.
In addition, example like that as shown, in the situation that buoyancy aid 97 is the type of rotation, preferably be configured to, the pivot of buoyancy aid 97 (namely, in diagram, detect axle 96x) with respect to the flowing or all mobile approximate right angle that becomes of handled thing of secondary reduction thing, while overlooking, with respect to what shake screening frame 20, shake direction.Like this, because the rotation direction of the flow direction of handled thing and the buoyancy aid 97 contacted with it is consistent or approach, so buoyancy aid 97 successfully move, with respect to the variation of handled thing amount, accurately and sensitively reacts.
This occasion, for the action that makes buoyancy aid 97 more smooth, be preferably following mode, center of rotation direction one side's side of buoyancy aid 97, particularly as shown example like that in the transfer direction downstream of movable stand section 22, setting arranges panel 98, and this panel 98 is in the roughly direction of quadrature (with the rotation direction almost parallel of sensor strut 97) extension of the center of rotation with respect to buoyancy aid 97.Like this, the effect of shaking formed by movable stand section 22, even the moving direction of handled thing skew, because moving direction is limited by panel 98 near this buoyancy aid 97, therefore the flow direction of handled thing is roughly consistent with the direction of rotation of the buoyancy aid 97 contacted with it, and buoyancy aid 97 can further successfully move.
In addition, as long as the shape of buoyancy aid 97 is suitably design, but preferably example is such as shown, the part at least contacted with handled thing (being the contactless state that there is no handled thing in illustrated example, the face of the moving direction upstream side of handled thing) is the arc curve of stretching out at the pars intermedia of glide direction.
On the other hand, generally on movable stand 22, the handled thing amount is inhomogeneous, particularly the after-treatment thing also stomodaeum 43a below near the handled thing amount maximum.Therefore, bed thickness detecting sensor 95 preferably is configured to and detects near the after-treatment thing thickness of the layer of the handled thing that shakes screening frame 20 stomodaeum 43a also.Therefore, in illustrated example, buoyancy aid 97 is configured in to the after-treatment thing also near stomodaeum 43a.
