(flexible linkage mechanism)
Between the operating stick 13 in steering unit U1 and output operating body 71, behaviour is followed to show output operating body 71 Make state that the wobbling action of bar 13 integrally moves and output operating body 71 does not follow operating stick 13 integrally and allows to operate Bar 13 individually carries out the mode of the state of wobbling action, is provided with flexible linkage mechanism I.
The flexible linkage mechanism I is constituted as follows.
That is, flexibly linkage mechanism I has: helical spring 74, before being wound in the oscillating deck part 71B of output operating body 71 The boss portion 71A of square side;Card rationed marketing 73, from oscillating deck part 71B, side protrusion is formed forwards;And locking hook portion 70b, from The wobbling action of operating stick 13 and around the lower end of the operation bracket 70 of the swinging center x1 wobbling action of axle portion 61 towards defeated 71 lateral bend of operating body is formed out.
As shown in (a) of Figure 13, in the state that operating stick 13 is located at neutral position N, around the operation of the first rotation section 60A The central hub x3 of the swinging center x1 of bar 13, the central hub x2 of locking hook portion 70b and card rationed marketing 73, which match, to be set as passing through It the swinging center x1 of operating stick 13 and is arranged on the plumb line L1 of shaft.
That is the line segment L2 of the central hub x2 of the swinging center x1 and locking hook portion 70b of connection operating stick 13, connection The line segment L3 of the central hub x3 of the card rationed marketing 73 of swinging center x1 and output operating body 71 is in and passes through the pendulum of operating stick 13 Moving axis heart x1 and the consistent state of plumb line L1 along shaft.
At this point, the both ends for being wound in the helical spring 74 of boss portion 71A are set as sandwiching operation bracket 70 rearward The card rationed marketing 73 outstanding of side forwards of the locking hook portion 70b that is formed by bending and output operating body 71, in being allocated in the lead The state of the two sides of straight line L1.
Although in addition, do not recorded in Figure 13, as shown in Fig. 6 and Fig. 8, the axle portion 61 to the first rotation section 60A into The bearing boss portion 51 of the bar supporting frame 50 of the chimeric bearing of row is wound with the neutral return spring 75 of steering, the steering neutrality return bullet It is held in the palm to sandwich the fixation card rationed marketing 52 being provided projectingly from bar supporting frame 50 towards front from two sides and from operation at the both ends of spring 75 The state of seat 70 towards the operation pin 70c that rear extends are arranged.
As shown in (b) of Figure 13, when operating stick 13 is by (or right) swinging operation predetermined angular to the left, locking hook portion 70b around the first rotation section 60A swinging center x1 according to clockwise oscillation in figure, be accompanied by this, card rationed marketing 73 is also via spiral Spring 74 is to same direction swinging operation.Linkage cable 82 is stretched with the swing of the card rationed marketing 73, steering control valve V1 quilt Turn round side handover operation to the left (referring to Fig. 4).In this state, the plumb line relative to the swinging center x1 by operating stick 13 L1 links the line segment L2, connection swinging center x1 and card rationed marketing 73 of the central hub x2 of swinging center x1 and locking hook portion 70b The line segment L3 of central hub x3 is by swinging operation equal angular.
Although turning to the one end of neutral return spring 75 engaging in fixed card rationed marketing 52 at this point, do not record in Figure 13, Another side is engaging in locking hook portion 70b, thus the pendulum that the interval of fixed card rationed marketing 52 and operation pin 70c pass through operation pin 70c It is dynamic and around the swinging center x1 elastic dilatation.Become to turn to as a result, neutral return spring 75 to neutral side to operating stick 13 into Row returns to the state of force.But helical spring 74 keeps retaining wedge to determine the state of hook portion 70b and card rationed marketing 73 around swinging center X1 is swung, and therefore, the helical spring 74 of the state is not acted on as the swing development of resistance of operating stick 13.
(scheme when making steering control valve V1 reach left rotary position L and the linkage cable 82 for being linked to fixed pin 72 stretches In stroke-end position) when, steering cluth (not shown) switches to a left side via the oil circuit switched by steering control valve V1 Turn state, travel machine body A carry out left revolution.When travel machine body A being made to carry out right-hand rotation, by the swinging operation to the right of operating stick 13 Predetermined angular.Locking hook portion 70b is according to counter-clockwise swing as a result, the steering pushed by the linkage cable 82 being made of push-pull wire Control valve V1 is switch operated to right-hand rotation position R, travel machine body A and carries out right-hand rotation.
(c) of Figure 13 shows following state: the steering control valve that the linkage cable 82 by being linked to fixed pin 72 stretches V1 reaches left rotary position L (stroke-end position in figure), and operating stick 13 (is to the left further right in Figure 13 Side) swinging operation, thus locking hook portion 70b around the first rotation section 60A swinging center x1 according to clockwise oscillation in figure, Xiang Yuan The side central hub x3 from card rationed marketing 73 is mobile.At this point, passing through axis branch component 60 and bar supporting frame 50 for operating stick 13 The first limiting unit 55 abut, bigger swing can be limited.
In this state, the plumb line L1 relative to the swinging center x1 by operating stick 13, with connection swinging center x1 It is compared with the line segment L3 of the central hub x3 of card rationed marketing 73, links the central hub x2's of swinging center x1 and locking hook portion 70b Line segment L2 is obtained bigger by swinging operation.
This is operating stick 13 from state shown in Figure 13 (b) by further (being right in Figure 13) swinging operation to the left State.In this state, locking hook portion 70b around the first rotation section 60A swinging center x1 according to clockwise oscillation in figure simultaneously More than stroke-end position, but pass through the fixed pin 72 of linkage cable 82 and the steering control valve V1 connection for having reached end of travel Still maintain state shown in (b) of original Figure 13.
Thus, for example even if due to operating stick 13 swinging operation amount by bar guide groove set etc., steering control valve V1's The position of end of travel and the swinging operation extreme position of operating stick 13 are inconsistent, and operating stick 13 is more than the row of steering control valve V1 Journey terminal position and redundantly operate to the state of transfiniting, the operating force of the operating stick 13 does not pass to steering control valve V1 yet, from And it can be easy to use.
In the case where this transfinites state, the elastic applied force of helical spring 74 is resisted at the interval of locking hook portion 70b and card rationed marketing 73 And it is expanded around swinging center x1.Therefore, in addition to neutral side to operating stick 13 carry out return force steering neutrality return spring Except 75 applied force, the elastic applied force of helical spring 74 is also played as the operation resistance of the swinging operation to operating stick 13 Effect.It is also advantageous on this point of readily recognizing that the nuisance operation for having carried out operating stick 13 as a result,.

Between the operating stick 213 in steering unit U1 and output operating body 271, it is provided with flexible linkage mechanism I, so that Show the state and output operating body 271 that output operating body 271 follows the wobbling action of operating stick 213 integrally to move The state for not following operating stick 213 integrally and operating stick 213 being allowed individually to carry out wobbling action.
The flexible linkage mechanism I is constituted as follows.
That is, flexibly linkage mechanism I is by helical spring 274, operation with opening 271C and in operation opening 271C Internal diameter and operating shaft 272 outer diameter between there are diameter differences to constitute, the helical spring 274 is wound in output operating body 271 Oscillating deck part 271B front side boss portion 271A, the operation is formed in oscillating deck part 271B with the 271C that is open.
As shown in (a) of Figure 25, in the state that operating stick 213 is located at neutral position, around the operating stick of the second shaft portion 262 The axle center x3 of 213 swinging center x1, the axle center x2 of operating shaft 272 and card rationed marketing 273, which match, to be set as along operating stick 213 Shaft direction straight line L1 on arrange.
That is the line segment of connection swinging center x1 and the axle center x2 of the operating shaft 272 on the shaft of operating stick 213 The line segment L3 of the axle center x3 of L2, connection swinging center x1 and card rationed marketing 273 are in the swinging center x1's by operating stick 213 The consistent state of plumb line L1.
At this point, the both ends for being wound in the helical spring 274 of boss portion 271A are set as sandwiching before output operating body 271 Square side operating shaft 272 outstanding and card rationed marketing 273, operating shaft 272 are located at the operation of output operating body 271 with being open in 271C Center portion.
Although in addition, not recorded in Figure 25, as shown in Figure 21 and Figure 23, in the extension shaft portion of the second shaft portion 262 262B is wound with the neutral return spring 275 of steering, and the both ends of the steering neutrality return spring 275 from two sides to sandwich from holding Framework 263 is arranged towards the state of the rear neutral banking pin 263A being provided projectingly and operating shaft 272.
As shown in (b) of Figure 25, when operating stick 213 is by (or right) swinging operation predetermined angular to the left, operating shaft 272 around the second shaft portion 262 swinging center x1 according to clockwise oscillation in figure, be accompanied by this, card rationed marketing 273 is also via spiral bullet Spring 274 is to same direction swinging operation.Operation cable 282 is stretched with the swing of the card rationed marketing 273, steering control valve V1 quilt Turn round side handover operation (referring to Fig.1 9) to the left.In this state, relative to the vertical of the swinging center x1 by operating stick 213 Line L1 links the line segment L2 of the axle center x2 of swinging center x1 and operating shaft 272, links the axis of swinging center x1 and card rationed marketing 273 The line segment L3 of heart x3 is by swinging operation equal angular.
Although turning to the one end of neutral return spring 275 engaging in neutral banking pin at this point, not recording in Figure 25 263A, another side is engaging in operating shaft 272, so that the interval of neutrality banking pin 263A and operating shaft 272 passes through operating shaft 272 Swing and around the swinging center x1 elastic dilatation.Become to turn to neutral return spring 275 to neutral side as a result, to operating stick 213 return the state of force.But helical spring 274 keeps the state of clamping operating shaft 272 and card rationed marketing 273 around pendulum Moving axis heart x1 is swung, and therefore, the helical spring 274 of the state is not acted on as the swing development of resistance of operating stick 213.
When making steering control valve V1 reach left rotary position L and the operation cable 282 that is linked to card rationed marketing 273 stretches When (stroke-end position in figure), steering cluth (not shown) is switched to via the oil circuit switched by steering control valve V1 Left turn state walks body A certainly and carries out left revolution.Make to swing operating stick 213 to the right from when walking body A progress right-hand rotation Operating provision angle.Card rationed marketing 273 is turned according to counter-clockwise swing by what the operation cable 282 being made of push-pull wire pushed as a result, It is switch operated to control valve V1 to right-hand rotation position R, walks body A certainly and carry out right-hand rotation.
(c) of Figure 25 shows following state: the course changing control that the operation cable 282 by being linked to card rationed marketing 273 stretches Valve V1 reaches left rotary position L, and operating stick 213 is by (being right in Figure 25) swinging operation to the left, and operating shaft 272 is around the The swinging center x1 of two axle portions 262 keeps the limitation of framework 263 with opening 263B's according to clockwise oscillation in figure, with being formed in The ora terminalis that is open abuts, so as to limit bigger swing.In this state, relative to the swinging center x1 for passing through operating stick 213 Plumb line L1 link swinging center x1 and behaviour compared with the line segment L3 of connection swinging center x1 and the axle center x3 of card rationed marketing 273 Make the axle center x2 of axis 272 line segment L2 obtained by swinging operation it is bigger.
This state shown in Figure 25 (b) that is operating stick 213 is by the further state of swinging operation to the left.In the shape Under state, operating shaft 272 around the second shaft portion 262 swinging center x1 according to clockwise oscillation in figure and with limitation opening 263B The ora terminalis that is open abuts, but still by operation cable 282 and the card rationed marketing 273 for the steering control valve V1 connection for having reached end of travel Maintain state shown in (b) of original Figure 25.
Thus, for example even if due to operating stick 213 swinging operation amount by bar guide groove set etc., steering control valve V1's The position of end of travel and the swinging operation extreme position of operating stick 213 are inconsistent, and operating stick 213 is more than steering control valve V1's Stroke-end position and redundantly operate to the state of transfiniting, the operating force of the operating stick 213 does not pass to steering control valve V1 yet, So as to convenient to use.
In the case where this transfinites state, the elastic applied force of helical spring 274 is resisted at the interval of operating shaft 272 and card rationed marketing 273 And it is expanded around swinging center x1.Therefore, in addition to neutral side to operating stick 213 carry out return force steering neutrality return spring Except 275 applied force, the elastic applied force of helical spring 274 is also used as the operation resistance of the swinging operation to operating stick 213 It plays a role.It is also advantageous on this point of readily recognizing that the nuisance operation for having carried out operating stick 213 as a result,.
(d) of Figure 25 shows following state: even if state shown in (a) of the operating stick 213 from Figure 25 is grasped to the left Make a certain degree, also due to soil is attached to steering control valve V1 etc. and can not be by the elastic applied force of helical spring 274 Keep card rationed marketing 273 mobile.At this point, the plumb line L1 relative to the swinging center x1 by operating stick 213, links swinging center x1 Line segment L2 with the axle center x2 of operating shaft 272 links the axis of swinging center x1 and card rationed marketing 273 by swinging operation predetermined angular The line segment L3 of heart x3 is kept and the consistent position plumb line L1.
In this state, the side Xiang Zhongli return to operating stick 213 application of the neutral return spring 275 of steering of force Power and the elastic applied force of helical spring 274 play a role as the operation resistance of the swinging operation to operating stick 213.Wherein, The elastic applied force of helical spring 274 acts on card rationed marketing 273, acts on steering control valve V1 to the left via operation cable 282 Turn round the direction of side handover operation.But when the elasticity that the operation resistance of steering control valve V1 is greater than the helical spring 274 applies When power, even if making the wobble to the left of operating stick 213, to make operating shaft 272 in the operation opening of output operating body 271 It is swung in the range of 271C, also shows that state of the card rationed marketing 273 not with moving with it.
In the structure of the present invention, use opening 271C inserted with operating shaft in the operation for being formed in output operating body 271 272, it therefore, in this case, also can be so that the operating shaft 272 be connected to the operation state of the inner peripheral of opening 271C Forcibly by operating stick 213 around swinging center x1 swinging operation.As a result, by the manual operation power to operating stick 213 via operation Axis 272 and output operating body 271 are directly passed to card rationed marketing 273, as shown in (c) of Figure 25, can grasp to card rationed marketing 273 Make, until steering control valve V1 reaches the position of end of travel.
In addition, use opening 271C inserted with operating shaft 272 being thusly-formed the operation in output operating body 271, it can be from behaviour Make axis 272 and the operating force of operating stick 213 directly is applied to output operating body 271, therefore following usage can also be carried out.For example, When output operating body 271 being made to be difficult to mobile because of adhesion-tight of the soil to steering control valve V1 etc., by the way that operating shaft 272 is rushed It is resisted against to hitting property the operation inner peripheral etc. of opening 271C, makes to export operating body 271 to steering control valve V1 imparting impact Operating force, to can also be easy to operate steering control valve V1.
To pass through the side for the limit for abutting the swinging operation range come setting operation bar 213 with the rear end side of operating shaft 272 Formula, which is formed in, keeps the limitation of framework 263 to be formed as follows with opening 263B.
That is limitation position in the inner peripheral of opening 263B, opposed relative to the moving direction of operating shaft 272 The left and right sides inner peripheral be formed as with around also as the oscillation center of the operating shaft 272 i.e. swinging center x1 of operating stick 213 Circular arc it is orthogonal or substantially orthogonal, operating shaft 272 is abutted with the inner peripheral at left and right sides of this.
Also, the limitation is following position with the position of inner peripheral of the left and right sides of opening 263B: operating shaft 272 via Operation opening 271C keeps the card rationed marketing 273 for being formed in output operating body 271 mobile, can operate steering control valve V1 to row Journey end.
In addition, limitation is abutted with opening 263B by the moving direction relative to operating shaft 272 come setting operation bar 213 The limit of swinging operation range, but operating shaft 272 is not made to be connected to the inner peripheral of only slightly inclined up or down, but make with The inner peripheral for the left and right that the opposed state of moving direction relative to operating shaft 272 abuts abuts.Therefore, it is easy accurately to set Determine the limit of the swinging operation range of operating stick 213, in this regard favorably.
(operation inputting part)
As shown in figure 26, the upper surface part of the grip part 213a of operating stick 213 is provided with operation inputting part 290.The behaviour Make input unit 290 for height adjustment signal to be sent into control device 283, the reel lifting device to reel lifting device 205A The rake that the rake that 205A is used to have the top of feeder 208 holds together reel 205 holds together height and carries out height change.

For example, being grasped even by the lifting that the operation of the left and right directions of operating stick 213 carries out harvesting pretreatment unit C Make, even the harvester for operating the structure of steering operation for walk certainly body A in the front-back direction by operating stick 213.
Other structures use structure same as the above embodiment.
(other embodiment 4)
In the above-described embodiment, illustrated to pass through spiral shell being attached to steering control valve V1 etc. due to soil In the case where the mobile card rationed marketing 273 of elastic applied force for revolving spring 274, so as to operating shaft 272 and be formed in output operating body 271 Operation with opening 271C inner peripheral abut state, forcibly by operating stick 213 around swinging center x1 swinging operation, thus Card rationed marketing 273 can be operated, until steering control valve V1 reaches the harvester of the structure of the position of end of travel, but unlimited In this.
For example, the structure as shown in (a)~(d) of Figure 28 can be used.
In this configuration, as shown in (c) of (b) of Figure 28 and Figure 28, the operation for being formed in oscillating deck part 271B is used The diameter that the internal diameter of opening 271C and the diameter difference of the outer diameter of operating shaft 272 are formed to be slightly larger than structure shown in above-mentioned Figure 25 is poor.
Therefore, as shown in (b) of Figure 28, made in operating stick 213 by (or right) swinging operation predetermined angular to the left After steering control valve V1 reaches left rotary position L (stroke-end position in figure), operating stick 213 is by further to Xiang Tongfang To when operation, as shown in (c) of Figure 28, even if operating shaft 272 around the second shaft portion 262 swinging center x1 according to clockwise in figure It swings and is abutted with limitation with the opening ora terminalis of opening 263B, also do not abutted with operation with the inner edge of opening 271C.
Therefore, have the advantages that the position without making steering control valve V1 reach end of travel is abutted with operating shaft 272 In the operation position consistency of opening 271C, it is not necessary to it is required that high-precision processing.
Also, as shown in (d) of Figure 28, helical spring can not be passed through being attached to steering control valve V1 etc. due to soil It, can be so that operating shaft 272 be connected to operation the interior of 271C that be open in the case where the mobile card rationed marketing 273 of 274 elastic applied force The state of periphery, forcibly by operating stick 213 around swinging center x1 swinging operation.
However, the diameter difference of the operation internal diameter of opening 271C and the outer diameter of operating shaft 272 is big in the structure, therefore, even if Operating stick 213 is according to clockwise oscillation in figure and is operated to the position abutted with limitation with the opening ora terminalis of opening 263B, Become state shown in dummy line in (c) of Figure 28.That is operation is located at shown in appended drawing reference 271C ' with opening 271C Position, card rationed marketing 273 are located at position shown in appended drawing reference 273 ', steering control valve V1 can not imperative operation to row is fully achieved The position of journey end.
In this way, in the case where being adhered to due to soil etc. keeps resistance big, steering control valve V1 can not imperative operation to complete Reach the position of end of travel, but can move it near end of travel.In addition, in general, in the attachment due to soil In the case where generating resistance, there is following tendency: when making it force mobile a certain degree, being generated due to the attachment of soil Resistance disappears from midway, so as to unimpededly operate to end of travel.
It should be noted that as described above, can also change limitation with opening 263B left and right open end it is intermarginal away from From, rather than increase the diameter for being formed in the operation internal diameter of opening 271C and the outer diameter of operating shaft 272 of oscillating deck part 271B The structure of difference.
That is the distance intermarginal with the open end of the left and right of opening 263B is limited it is also conceivable that reducing, so that even if Operating shaft 272 in figure of the swinging center x1 according to Figure 28 of the second shaft portion 262 clockwise oscillation and with limitation opening 263B Opening ora terminalis abut, operating shaft 272 also not with operation be open 271C inner edge abut.Also it can obtain and be formed in as a result, The operation of oscillating deck part 271B is formed to be slightly larger than above-mentioned figure with the diameter difference of the internal diameter of opening 271C and the outer diameter of operating shaft 272 The structure of the diameter difference of structure shown in 25 similarly acts on.
