The protuberance that the side plate 17B that discharges chute 17 rear sides certainly among each connecting rod 17C up and down that the free end side of guiding parts 42 utilization discharge chutes 17 has rearward gives prominence to, fixed configurations is in discharging chute 17.Be formed with the gathering sill 42A that extends along the grain channeling direction of discharging chute 17 at guiding parts 42.
According to said structure, by the ladder bolt 45 of holder 44 is operated towards fastening releasing direction, nut part 47 is turned along the direction away from ladder bolt 45, thereby can unclamp the clamping that the guiding parts 42 of the abutting part 47B that utilizes packing ring 46 and nut part 47 and supporting arm 43 carry out.Thus, can allow holder 44 to slide with respect to guiding parts 42, be that fulcrum swings up and down thereby can make discharge chute 17 with bolster 40.And, swing up and down by this, can make the free end of discharging chute 17 near facing upward the maximum angle of the regulation of sending conveying plant 16 and making the free end of discharging chute 17 infinitely change the inclination angle of discharging chute 17 between away from the minimum angles of facing upward the regulation of sending conveying plant 16.
After changing this inclination angle, the ladder bolt 45 of holder 44 is operated along fastening direction, thereby nut part 47 is turned along the direction near ladder bolt 45, can strengthen utilizing the guiding parts 42 of abutting part 47B of packing ring 46 and nut part 47 and the clamping that supporting arm 43 carries out.Thus, can stop holder 44 to slide with respect to guiding parts 42, thereby can fix maintenance with the inclination angle after changing with discharging chute 17.
Consequently, can fall arbitrarily between the drain position of posture from facing upward the "Left"-deviationist of sending conveying plant 16 to leave becoming along facing upward the stowed position of sending the posture that conveying plant 16 hangs down and becoming the free end side of discharging chute 17, infinitely change the swinging position position of discharging chute 17.That is, inclination angle change mechanism 41 is that the drain position change mechanism of the drain position of fulcrum works as can infinitely changing what discharge chute 17 with bolster 40.
If change to discharge the drain position of chute 17, then can change the grain that flows down by discharging chute 17 guiding at body right lateral discharge position and discharge height, thereby carry out the discharge of the grain that adapts with job status easily.In addition, if change the drain position of discharging chute 17, then change the inclination angle of discharging chute 17, thereby can regulate the speed that flows down of the grain that flows down by discharging chute 17 guiding.Consequently, can change the inclination angle of discharging chute 17 according to the flowability that changes because of the amount of moisture of grain etc., by this change, the speed that flows down of grain can be adjusted to suitable speed, thereby avoid easily causing discharging chute 17 generation grain obstructions etc. because flowability reduces.
In addition, have each the connecting rod 17C that discharges chute 17 in the free end side of discharging chute 17, therefore, not only above-mentioned each connecting rod 17C can be also used as the support unit of guiding parts 42, and the handle can be also used as swinging operation discharge chute 17 time.
As Fig. 2, Fig. 3, Fig. 5, Fig. 9 and shown in Figure 10, discharge chute 17 and constitute the position that is positioned under the situation of stowed position than the close body inboard of right flank of grain collecting box 11 being in.Thus, carrying out switching to the stowed position by discharging chute 17 under the situations such as operation is travelled or movement is travelled, can prevent to damage such unfavorable condition because discharge chute 17 in travelling contacts with other objects.
As Fig. 3～Fig. 7, Fig. 9 and shown in Figure 10, discharge chute 17 constitutes can utilize with its maintaining body 48 to the arrival action interlock of stowed position and fixedly remains on the stowed position.Maintaining body 48 constitutes that the clamping rpole 49 that the toe lateral of utilizing conveying plant shell 21 has and the base plate 17A that discharges chute 17 have can strain holder 50, by making holder 50 move clamping in linkage and be embedded in clamping rpole 49 with discharging chute 17 to the arrival of stowed position, can fixedly remain on the stowed position with discharging chute 17.
The holder 44 of inoperation inclination angle change mechanism 41 thus, switches under the situation of stowed position will discharging chute 17, even also can automatically fixedly remain on the stowed position with discharging chute 17.Thus, can prevent following unfavorable condition reliably: unexpectedly switch to drain position from the stowed position and contact with other objects because the vibration of the body in travelling etc. causes discharging chute 17.
As Fig. 1, Fig. 3～Fig. 9 and shown in Figure 11, to discharge the cover body 51 that chute 17 tops fly out from outlet 16A certainly to discharging chute 17 mobile grain be used to preventing, via a pair of hinge 52 that is configured in the upper right end of members of frame 21B, can swing up and down link with the members of frame 21B of conveying plant shell 21.
Discharging chute 17 constitutes wideer than the transverse width of cover body 51.And, job position at grain collecting box 11, be positioned at the forward state that more leans on the body front side than the pivot X that faces upward square auger conveying plant 16 with the center on the transverse width direction of discharging chute 17, be configured in and face upward the right side of sending conveying plant 16 discharging chute 17, make the side plate 17B of its rear side be in the state with the outside adjacency of cover body 51.And, the internal configurations of members of frame 21B have with from outlet 16A to discharging grain that chute 17 the flows guided plate 53 near body channeling conduct ventrally.
Namely, form wideer than the transverse width of outlet 16A by the transverse width that makes cover body 51, not only can utilize cover body 51 to prevent from flying out from discharging chute 17 tops to discharging chute 17 mobile grain from outlet 16A, and can prevent from spilling from two cross sides of cover body 51 to discharging chute 17 mobile grain from outlet 16A.In addition, because the transverse width of cover body 51 is narrower than the transverse width of discharging chute 17, therefore, can utilizes discharge chute 17 to catch reliably by cover body 51 and stop the grain that flies out.
In addition, send conveying plant 16 to discharge chute 17 with forward state configuration with respect to facing upward, discharge chute 17 under the job position state and send conveying plant 16 rearward overhangs from facing upward thereby can reduce to be positioned at grain collecting box 11.Thus, for stalk conveying plant 8 and stalk treating apparatus 9 that the rearward end with sheller unit 6 links configuration, be difficult to cause following worry: by send conveying plant 16 facing upward of grain collecting box 11 rears the above-mentioned discharge chute 17 that is positioned at stalk conveying plant 8 and stalk treating apparatus 9 right side sides is installed, make grain collecting box 11 when job position is swung to maintenance position, touching stalk conveying plant 8 and stalk treating apparatus 9 with the one swing of grain collecting box 11.
And, because the internal configurations at members of frame 21B has guided plate 53, so, although discharge chute 17 with forward state configuration facing upward the right side of sending conveying plant 16, still can face upward grain that the outlet 16A that send conveying plant 16 flows out certainly to the width center side channeling conduct of discharging chute 17.Thus, can make grain from outlet 16A is not to be partial to the state of the width rear end side of discharging chute 17 but to flow down discharging chute 17 with the state of the few homogenising of the skew on the width.Consequently, can avoid because causing grain rearward to overflow such unfavorable condition from the rearward end of discharging chute 17 under the state flow of grain with deflection width rear end side.
As Fig. 3～Fig. 9 and shown in Figure 11, the rear end at the base portion of discharging chute 17 disposes the armite 17D that stretches out to grain channeling direction upstream side from this rearward end.The side plate 51B of rear side in cover body 51 disposes the armite 51C that stretches out laterally from the end of the grain channeling direction upstream side of this side plate 51B.And, discharging chute 17 and cover body 51 links in linkage via armite 17D, the 51C of the connect mechanism 55 that is made of connecting rod with them, make and discharge chute 17 the closer to the stowed position, more reduce at the opening 54 of discharging formation between chute 17 and the cover body 51, the free end side of discharging chute 17 from face upward send conveying plant 16 more away from, opening 54 more increases.
In said structure, consider and discharge chute 17 the closer to the stowed position, the inclination angle of discharging chute 17 more increases, and the flow velocity of the grain that is discharged from chute 17 guiding and flows down is all the more fast, grain discharge rate in unit interval more increases this situation, constitute and discharge chute 17 the closer to the stowed position, make the opening 54 that is formed between discharge chute 17 and the cover body 51 more little, interior grain amount by opening 54 of unit interval is reduced.Thus, can suppress to cause the grain discharge rate in the unit interval to increase this situation along with discharging chute 17 near the stowed position.
On the contrary, consider the free end side of discharging chute 17 from face upward send conveying plant 16 more away from, the inclination angle of discharging chute 17 more reduces, and the flow velocity of the grain that is discharged from chute 17 guiding and flows down is more slack-off, grain discharge rate in unit interval more reduces this situation, constitute the free end side of discharging chute 17 from face upward send conveying plant 16 more away from, more increase the opening 54 that forms between chute 17 and the cover body 51 discharging, to increase in the unit interval grain amount by opening 54.Thus, can suppress along with the free end side of discharging chute 17 from face upward send conveying plant 16 away from and cause the grain discharge rate in the unit interval to reduce this situation.
Namely, no matter the inclination angle of discharge chute 17 how, can make the grain discharge rate constant in the unit interval, thus, can suppress following unfavorable condition: increase to discharge the inclination angle of chute 17 and the discharge position that is discharged from the grain of chute 17 guiding more more reduces away from, the grain discharge rate in the unit interval from body and causes grain to discharge efficient more reducing.
As Fig. 5～Fig. 9 and shown in Figure 11, dispose the block 17E that is constituted by the pin outstanding towards the rear at the armite 17D that discharges chute 17.By making connect mechanism 55 and this block 17E butt, restriction is discharged chute 17 and is sent conveying plant 16 to swinging away from direction from facing upward.
As Fig. 3～Fig. 5 and Fig. 9～shown in Figure 11, dispose butt parts 56 at support 25, these butt parts 56 are by abutting to the base plate 17A of the discharge chute 17 that moves with grain collecting box 11 one of swinging to maintenance position, remove to discharge chute 17 and be held mechanism 48 in the fixedly maintenance of stowed position, make the free end side of discharging chute 17 from face upward send conveying plant 16 away from.Butt parts 56 are made of the roller that outer embedding with the relative rotation is configured on the bolster 57 that support 25 hangs down, make job position at grain collecting box 11, these butt parts 56 with the state of the back side adjacency of the base plate 17A that discharges chute 17 by the discharge chute 17 that is in the stowed position.
According to said structure, if fixedly remain under the state of stowed position grain collecting box 11 swung towards maintenance position utilizing maintaining body 48 will discharge chute 17, the base plate 17A that then discharges chute 17 cross butt parts 56 and with its butt, the free end side of discharging chute 17 is boosted, thus, utilize the fixedly maintenance of the chimeric discharge chute 17 that carries out of clamping of the clamping rpole 49 of maintaining body 48 and holder 50 to be disengaged automatically, discharge chute 17 swing of rising.
Thus, can prevent following unfavorable condition: touch in its moving direction downstream towards the discharge chute 17 of maintenance position and grain collecting box 11 one swing and connect mechanism 55 and swing to the stalk treating apparatus 9 of the close maintenance position of grain collecting box 11 etc.Consequently, even if stalk treating apparatus 9 is being swung under the situation of maintenance position, also can make grain collecting box 11 to the right outside swing significantly of body, thereby can between sheller unit 6 and grain collecting box 11, guarantee roomy space.
As Fig. 1, Fig. 3～Fig. 5, Fig. 9 and shown in Figure 11, discharging the free end of chute 17, the state that takes the shape of the letter U with the shape of seeing from the grain channeling direction has by what transparent resin plate constituted and has a flexible auxiliary shoot 58.And, at the free end of auxiliary shoot 58, dispose circular hole 58A that the rear and front end that is passed in this free end forms change free end transverse width be with 59.
According to said structure, for example the discharge object at grain is under the situations such as boxcar, be with 59 by unclamping, the frontal width of the grain outlet side of auxiliary shoot 58 can be formed roomy state, thus can be so that grain be diffused into the state in roomy zones such as boxcar that it is discharged.
In addition, discharge object at grain is under the situations such as grain bag, be with 59 by tightening, the frontal width of the grain outlet side of auxiliary shoot 58 can be formed narrow cylindric, thereby can be so that grain focuses on the state in narrow and small zones such as grain bag that it is discharged.
Namely, though be to use with 59 and had the simple structure of flexible auxiliary shoot 58, but the frontal width of the grain outlet side of auxiliary shoot 58 easily can be altered to the size that discharge object with grain etc. adapts, thereby can carry out the discharge of the grain that the discharge object etc. with grain adapts well.
As Fig. 1～Fig. 6, Fig. 9 and shown in Figure 11, the side plate 17B that discharges chute 17 rear sides makes the top of its base portion side to tilt to the body rear side the closer to the offside mode in the body rear side of the upper side of base portion side.Thus, can prevent that the side plate 51B of cover body 51 rear sides that the top sliding-contact because of the base portion side of the side plate 17B that discharges chute 17 rear sides is adjacent from causing being difficult to discharge the inclination angle alter operation of chute 17.
As Fig. 3, Fig. 5 and shown in Figure 10, first pillar 13 and second pillar 24 link parts 60 with their top binding by utilizing, thereby improve their intensity.
