(supporting construction)

Below the supporting construction of supporting mass 40 and the vertical framework 50 of use is described.

As shown in Figure 3 and Figure 6, supporting mass 40 is formed as column, has the lower support body supporting aforesaid tubular discharge cylinder portion 41C and divides 41 and be fixed on this lower support body integratedly and divide the cylindric upper support body on 41 tops to divide 42.

In supporting mass 40, lower support body divides 41 to have the hinge portion 41D embedding and be arranged at the supporting bore 10a of the above-below direction at vehicle body frame 10 rear portion in bottom, and is supported on vehicle body frame 10 rotatably mountedly.

The central axis of this hinge portion 41D and upper support body divide the central axis at the cylindric position of 42 to be positioned on same line each other, and these central axis constitute center of rotation and the vertical axis Y of paddy case E.That is, vertical axis Y becomes the center of rotation of the supporting mass 40 self that the central axis of hinge portion 41D and upper support body divide the central axis at the cylindric position of 42 consistent with the center overlooking area of supporting mass 40.And paddy case E is connected to the upper end of this supporting mass 40 via connection metal part 25, by being integrally constituted rotation, described vertical axis Y becomes the center of rotation of paddy case E.

Like this, the upper side of paddy case E is connected to the upper end of supporting mass 40 by connection metal part 25, and the lower support body that lower side is supported on supporting mass 40 via the discharge cylinder portion 41C being fixed on box main body 20 divides 41.Thus, paddy case E is can rotate around the center of rotation of supporting mass 40 and vertical axis Y in the state of upper and lower two-side supporting in supporting mass 40.

Lower support body divide 41 by have grain outlet 20B tubular discharge cylinder portion 41C, be formed at this tubular discharge cylinder portion 41C upper half side upside foot 41A, be formed at lower half side downside foot 41B, embed the hinge portion 41D of the supporting bore 10a of vehicle body frame 10 and be integrally formed and obtain.

The upper end side of upside foot 41A is connected to the bottom that upper support body divides 42, and lower end side and the upper half side of tubular discharge cylinder portion 41C are integrally formed.Upper end side and the lower half side of tubular discharge cylinder portion 41C of downside foot 41B are integrally formed, and bottom and hinge portion 41D are integrally formed.

As shown in Figure 6, lower support body divides 41 to be positioned at the mode of the position dividing the central axis at the cylindric position of 42 and the right outside side side skew of vertical axis Y-direction body from upper support body with the introducing cylinder portion 30A of the ancon 30 of the tubular discharge cylinder portion 41C and unloader F that are located thereon the pars intermedia in lower direction, the shape bent when being formed as backsight.That is, upper support body is made to divide the bottom of 42 to be obliquely installed in the mode be located outside body the closer to 41C side, tubular discharge cylinder portion with the downside foot 41B making the lower half side of tubular discharge cylinder portion 41C be connected with the upper end of hinge portion 41D with the upper half side upside foot 41A be connected of tubular discharge cylinder portion 41C.

Like this, although the introducing cylinder portion 30A of the ancon 30 of tubular discharge cylinder portion 41C, unloader F is positioned at the position dividing the right outside side side skew of the central axis Ji Zong center Y-direction body at the cylindric position of 42 from upper support body, but when overlooking as shown in Figures 7 and 8, divide the cylindrical portion of 42 overlapping with upper support body.Therefore, in the lateral direction, the upper support part 42 of supporting mass 40 is relative to the introducing cylinder portion 30A of the ancon 30 of unloader F to the inner side displacement certainly walking body A, but displacement is less.

Its result, the swinging center X of the introducing cylinder portion 30A of the ancon 30 of unloader F and upper support body can be divided the distance L2 between the central axis at the cylindric position of 42 and vertical axis Y to be set as dividing the radius sum of 42 little than the radius of introducing cylinder portion 30A and upper support body, therefore, it is possible to make the introducing cylinder portion 30A of the ancon 30 of supporting mass 40 and unloader F arrange more close in the lateral direction.

Supporting mass 40 is also connected to the vertical framework 50 erected on vehicle body frame 10.

(unloader)

Unloader F has vertical cylinder portion 31, and this vertical cylinder portion 31 is connected with the grain carriage direction downstream of the ancon 30 being positioned at end, introduction side.

Vertical cylinder portion 31 has the expelling tube 34 of straight tube-like in the mode of the longitudinal transport path R at Inner Constitution linearity and is arranged at the discharge screw feeder 35 of this expelling tube 34 inside, and have grain discharge opening 36 in discharge side end, grain guides to the direction orthogonal with the length direction of expelling tube 34 by this grain discharge opening 36.

Unloader F is configured to freely switch between discharge side end storage posture upward and discharge side end discharge posture toward the outer side.

As shown in Figure 4, under storage posture, the central axis Z (being equivalent to an axle center) in vertical cylinder portion 31 topples over slightly toward the inner side certainly walking body A relative to plumb line.Therefore, indulging a portion 31 when backsight is the posture tilted to the left.Under discharge posture, the central axis Z in vertical cylinder portion 31 is the posture a little near top compared with horizontal line, indulges the inclination attitude risen for right side in a portion 31 when backsight.

The base end side of discharging screw feeder 35 is configured to the double helix forming two helical members on screw conveyor shaft 35A, reliably can transport grain at this base end side.It should be noted that, screw conveyor shaft 35A is supported to and rotates freely centered by central axis Z.

A part of the screw conveyor shaft 21A of bottom screw feeder 21 inserts the introducing cylinder portion 30A inside of ancon 30, and the export cylinder portion 30B discharging the part insertion ancon 30 of screw feeder 35 is inner.The bevel gear mechanism 37 with the bevel-gear sett 37G rotated around mutually orthogonal axle center is set in ancon 30 inside, thus the driving force of this screw conveyor shaft 21A is delivered to the screw conveyor shaft 35A discharging screw feeder 35.

According to this drive structure, the driving force of bottom screw feeder 21 can be passed to via the bevel gear mechanism 37 of ancon 30 and discharge screw feeder 35.Discharge screw feeder 35 thereby, it is possible to be transported to from bottom screw feeder 21 by the grain of paddy case E, and discharge from the grain discharge opening 36 of the transport terminal of unloader F.

In this unloader F, when observing paddy case E from rear, the direction of rotation of bottom screw feeder 21 is to anticlockwise (counterclockwise).Therefore, when carrying out grain from unloader F, make this unloader F in storage posture, lift the moment of torsion in direction to vertical cylinder portion 31 effect of unloader F.

In this combine, the oscillation center of paddy case E and the central axis of supporting mass 40 and vertical axis Y are arranged at the position of the rear wall 20r near paddy case E.With this vertical axis Y for benchmark, the swinging center X of the axle center of screw conveyor shaft 21A and unloader F to be arranged on than this vertical axis Y from the position walked near lateral outer side on body A left and right directions, the central axis Z of unloader F is set in than the position of vertical axis Y near rear.

Like this, swinging center X is arranged at the lateral outer side from walking body A compared with vertical axis Y, and bottom screw feeder 21 is set to the lateral outer side skew to certainly walking body A, so the entirety of unloader F configures near from the outside portion walking body A.Under making the discharge side end of unloader F swing to the discharge posture in outside, effectively can utilize the length in the vertical cylinder portion 31 of unloader F, make grain outlet 20B be positioned at the position away from the end certainly walking body A and discharge grain.

And, as shown in Figure 4, under the state that paddy case E is in work posture and unloader F is in storage posture, the position of some overlap when the vertical cylinder portion 31 of supporting mass 40 and unloader F is arranged on backsight.Thereby, it is possible to make supporting mass 40 and unloader F close on the width walking body A, thus the space for arranging supporting mass 40 and unloader F can be saved.

(driving swing mechanism)

Below, the oscillatory gearing mechanism making unloader F fluctuate is described.

Oscillatory gearing mechanism is made up of two ejector half hydraulic cylinders 60 of telescopic drive.As shown in Figures 3 to 5, hydraulic cylinder 60 is located at unloader F and erects the supporting mass 40 on vehicle body frame 10.

That is, cylinder barrel 61 upper end being positioned at hydraulic cylinder 60 end side is connected to supporting mass 40 side, and piston rod 62 bottom being positioned at another side is connected to unloader F side.Below, the end of cylinder barrel 61 side is called first end, the end of piston rod 62 side is called the second end.

The pars intermedia position of the above-below direction of the supporting mass 40 connected at the first end of cylinder barrel 61 has tubular installation portion 40A, and this tubular installation portion 40A relatively rotates and is embedded in supporting mass 40 freely outward.This tubular installation portion 40A is used for installing bracket for mounting 44 described later and receiving portion 45.

Tubular installation portion 40A is positioned at the downside of the connecting portion being fastened on vertical framework 50 on vehicle body frame 10 and supporting mass 40 with the rotating engagement 52 of band plate-like in the installation position of supporting mass 40.The upper end side of tubular installation portion 40A is connected to the lower end side of rotating engagement 52, be fixed on the rotating engagement 52 of the band plate-like of vertical framework 50 also as preventing tubular installation portion 40A from departing from from top, and the mechanism limiting tubular installation portion 40A movement downwards works.

The first end of cylinder barrel 61 swings the bracket for mounting 44 being freely connected to the peripheral part being arranged on this tubular installation portion 40A via connecting pin 63.

The end and the second end that are positioned at the piston rod 62 of another side of hydraulic cylinder 60 swing the connection bracket 39 being freely connected to and being arranged in the vertical cylinder portion 31 of unloader F around connecting pin 64.Be embedded in position adjacent with ancon 30 in the vertical cylinder portion 31 of unloader F outside this connection bracket 39, and be installed on the strengthening part 38 of soldered fixing tubular.

In the hydraulic cylinder 60 so arranged, the first end be connected with supporting mass 40 is positioned at top and is positioned at the inner side from walking body A, and the second end be connected with unloader F is positioned at below and is positioned at the lateral outer side from walking body A.

As shown in Figure 3, the vertical axis Y of the supporting mass 40 on rear side of paddy case E is erected on during side-looking parallel with the central axis Z in the vertical cylinder portion 31 of unloader F.Unloader F separates the closely-spaced of regulation with supporting mass 40 in the longitudinal direction, and hydraulic cylinder 60 is arranged to be had in this closely-spaced space, centre line C L parallel with the central axis Z in the vertical cylinder portion 31 of unloader F with the vertical axis Y of supporting mass 40 when having a side-looking.

That is, the bracket for mounting 44 of supporting mass 40 side is rearward given prominence to than the end edge of the outer peripheral face of supporting mass 40 when side-looking, and the front-end edge of vertical cylinder portion 31 outer peripheral edges of connection bracket 39 when side-looking than unloader F of unloader F side is forwards given prominence to.Being connected to bracket for mounting 44 and the hydraulic cylinder 60 of connection bracket 39, to be mounted to its centre line C L when side-looking parallel or almost parallel with described vertical axis Y and central axis Z.

The swinging center X of unloader F is orthogonal with described vertical axis Y, central axis Z and centre line C L.Therefore, the possibility that when avoiding the unloader F fluctuate along with the flexible of hydraulic cylinder 60, hydraulic cylinder 60 is interfered with unloader F and supporting mass 40.

As shown in Figure 4, when backsight, the vertical cylinder portion 31 of unloader F, under unloader F is in storage posture, is accepted by receiving portion 45 described later with the state that its central axis Z topples over from the inner side walking body A a little relative to the vertical axis Y-direction of the supporting mass 40 erected on rear side of paddy case E.

Under this storage posture, the centre line C L of hydraulic cylinder 60, compared with the inclination of the central axis Z in the vertical cylinder portion 31 of unloader F, more tilts to the inner side certainly walking body A.

That is, the bracket for mounting 44 of supporting mass 40 side that the first end of hydraulic cylinder 60 connects is given prominence to than the outer peripheral face of supporting mass 40 to the right when backsight, and connecting pin 63 is positioned at right side ora terminalis than the outer peripheral face of supporting mass 40 near the position on right side.And the outer peripheral face of connection bracket 39 when backsight also than unloader F of the unloader F side that the second end of hydraulic cylinder 60 connects is given prominence to the right, connecting pin 64 is positioned at right side ora terminalis than the outer peripheral face of unloader F near the position on right side.The swinging center X of unloader F than the vertical axis Y of supporting mass 40 closer to the lateral outer side certainly walking body A.Its result, the left side lateral margin that vertical axis Y and swinging center X position deviation amount is in the lateral direction greater than the unloader F at the position, swinging center X place of unloader F and the left side lateral margin position deviation amount in the lateral direction of the unloader F at position contacted with receiving portion 45.Therefore, the unloader F inclined degree that supports than sustained portion 45 of hydraulic cylinder 60 is larger.

The inclination of hydraulic cylinder 60 contribute to the telescopic direction of hydraulic cylinder 60 to be set as make unloader F swimmingly fluctuate time make the line of force of hydraulic cylinder 60 close to the direction orthogonal with the central axis Z in the vertical cylinder portion 31 of unloader F as far as possible.And, owing to being provided with more outstanding than the right side ora terminalis of supporting mass 40 outer peripheral face and being connected with the bracket for mounting 44 of the first end of hydraulic cylinder 60, therefore, such as, compared with more outstanding than the left side ora terminalis of supporting mass 40 outer peripheral face with this bracket for mounting 44 situation, effectively can try one's best and shorten the length of hydraulic cylinder 60.

The second end of hydraulic cylinder 60 is connected to the connection bracket 39 be arranged on the strengthening part 38 of tubular, is embedded in position adjacent with ancon 30 in the vertical cylinder portion 31 of unloader F outside the strengthening part 38 of described tubular.Like this, connected by the position near ancon 30 in vertical cylinder portion 31, reduce the radius of turn of the second end around the track r1 of the swinging center X movement of unloader F, thus effectively can reduce the stroke of hydraulic cylinder 60.
