The posture changing mechanism 60 has a basic structure similar to that of the posture changing mechanism 60, but differs from the posture changing mechanism 60 in that it has a simple structure in which the engaging body is slidably engaged with the engaged body. In the present embodiment, the tension spring 64 is sandwiched between the upper left and right extension pieces 101 and the right swing support arm 51.
That is, the locking portion 62 extends rearward from the substantially central portion of the rear portion of the carry section support main body 107 to form the rear extension connecting plate 66, and the rear end of the rear extension connecting plate 66 is laterally And the front side of the distal end portion of the lateral elongated connecting plate 63 extending in an orthogonal state.
And an engaged portion 130 is provided in the middle portion of the upper left and right elongated pieces 101. The locked portion 130 is provided with a plate-shaped support piece 68 extending in the vertical direction from the middle portion of the upper left and right extension pieces 101 so as to be laterally laterally sideways, The upper and lower adjustment piece 131 is vertically slidably in contact with the upper and lower adjustment piece 131 so as to be adjustable in the vertical direction. The left and right end surfaces of the to-be-punched body 132 in the form of a bent plate are extended to the vertical adjustment piece 131. The locking object 132 includes a guide piece 134 having a low inclined plane 133 after topping and a to-be-engaged piece 136 having an engagement hole 135 opened in the front-back direction, And a receiving piece 137 extending rearward from the lower end.
The engaging operation body 70 includes an operating body main piece 73 of a straight rod shape extending in the front and rear direction, an engaging projection piece 140 as an engaging body formed at the front end of the main body 73 of the operating body, And a movable side handle piece 75 formed by extending the rear side end portion 73 from the rear end portion to the right side in a substantially right angle folded shape.
The engaging protrusion piece 140 is formed with a sliding contact surface 141 having a substantially hemispherical convex shape at the front end thereof so that the sliding contact surface 141 moves up and down along the inclined surface 133 of the locking object 132, The main piece 73 is moved back and forth in the forward and backward directions. The engaging protrusion piece 140 is inserted into the engaging hole 135 of the engaging piece 136 so as to be inserted and retracted. Here, the state in which the engaging protrusion piece 140 is inserted into the engaging hole 135 is in the engaging state (engaging position c), and the state in which the engaging protrusion piece 140 is extracted from the engaging hole 135 is in the disengaged state (Disengagement posture (d)). The main body 73 of the operating body is retreated rearward by sliding the sliding contact surface 141 downward along the inclined surface 133 of the locking body 132 and the sliding contact surface 141 is moved to the engaging hole 135 The operating body main piece 73 advances and moves forward by the urging force of a pressing spring 79 which will be described later so that the engaging projection piece 140 is engaged with the engaging hole 135. [
A tubular guide piece 72 having an axis extending in the forward and backward direction is fixed to the left side portion of the side extension connecting plate 63 in a transversely penetrating manner so that the front end portion of the operation body main piece 73 is inserted into the guide piece 72 in the forward and backward directions And is slidably penetrated. A pressing spring 79 is wound on the outer peripheral surface of the front portion of the main body 73 of the operating body so that the front end of the urging spring 79 is engaged with a flange-shaped spring locking piece 78 extending on the front portion of the outer peripheral surface of the main body 73 .
The posture changing operating member 45 is attached to the side elongating connecting plate 63 so as to be adjacent to the engaging operating member 70. That is, the posture changing operation body 45 has a tubular operation main piece 83 formed by extending in the front-rear direction, and a fixed side (left-hand side) And is formed as a handle piece 84. [ The connecting piece 150 is formed on the right half of the outer peripheral surface of the front end of the operation main body 83 by extending the connecting piece 150 to the right so that the connecting piece 150 is connected to the connecting bolt 151 . Here, the posture changing operation body 45 is disposed such that the longitudinal axis X of the operation main body 83 crosses the above-described pivot axis P (see Fig. 3).
In the operation main body 83, the main body 73 of the operating body is disposed concentrically and slidably movable forward and backward. A spring receiving portion 152 is formed in the middle portion of the operation main piece 83. The front portion of the operation main piece 83 located on the front side of the spring receiving portion 152 opens the left half and the rear portion of the operation main piece 83 located on the rear side of the spring receiving portion 152 is located on the right half side . A pressing spring 79 is disposed on the front portion of the operation main body 83 to bring the rear end of the pressing spring 79 into contact with the spring receiving portion 152. The movable side pull piece 75 of the engaging operation body 70 is projected to the right from the rear portion of the operation main piece 83 where the right half is opened. The fixed-side handle member 84 is arranged in the vicinity of the rear side of the movable-side handle member 75 of the engaging operation body 70 in a front-rear parallel relationship. 153 is a reinforcing rib.
In this way, the posture changing operation body 45 grasps the fixed-side handle member 84 and moves the waste-stone conveying device 18 to the waste-harvesting posture (a) and the stowage clogging-off posture (b) . At this time, when changing the position of the waste skid conveyor 18 from the waste conveying posture (a) to the debris clogging posture (b), the fixed side handlebar 84 and the movable side handlebar 75 are simultaneously held, The engaging projection piece 140 is withdrawn from the engaging hole 135 against the biasing force of the urging spring 79 by retracting the engaging projection piece 75 toward the fixed side handle piece 84 side, It is possible to release the engagement. When the posture changing operation body 45 is rotated upward in the disengaged state, the waste conveying device 18, which is tension-elastic biased to the tension spring 64, can be raised and rotated comfortably, (B) can be smoothly achieved.
As described above, the waste-stone conveying device 18 changes the attitude to the waste-transporting posture (a) and the waste-clogging-releasing posture (b) by operating the posture changing operation body 45 from the back side of the body through the posture changing mechanism 60 . Such a posture changing operation procedure will be described below.

The engaging protruding piece 140 is held in the disengagement posture d from the engaging position c to the disengagement position d by grasping the fixed side pull piece 84 and the movable side pull piece 75 of the posture changing operation body 45 simultaneously, Is changed. That is, the engaging projection piece 140 is extracted from the engaging hole 135 and disengaged. Then, since the waste-stone conveying device 18 is tension-elastic-biased upward by the tension spring 64, only by raising the fixed-side handle piece 84 and the movable-side handle piece 75, The apparatus 18 is pivoted about the pivot axis P to change its attitude from the waste transfer position a to the unblocking position b. Thus, the clogged straw can easily be taken out of the waste-stone transfer device 18.

The holding side grip piece 84 of the posture changing operation body 45 is lowered against the tensile elastic biasing force of the tension spring 64 so that the receiving piece 137 of the locking body 132 is laterally extended The engaging projection 140 can be engaged with the engaging hole 135 by bringing the lower end of the connecting plate 63 into contact. At this time, the sliding contact surface 141 formed at the front end of the engaging projection piece 140 is moved downwardly along the inclined surface 133 of the locking body 132 so that the main body 73 of the operating body 73 is pressed against the pressing spring 79 The operating body main piece 73 advances forward by the urging force of the urging spring 79 when the sliding surface 141 is fitted to the engaging hole 135 The engaging projection 140 is inserted into the engaging hole 135 and engaged. That is, the engaging projection piece 140 becomes the engaging posture c. As a result, the waste skid conveyance device 18 is changed from the stubble clogging posture b to the waste conveying posture a, and is held at the waste conveying posture a.
