It is configured to substantially coincide with the position of 4B.

  The canopy 10 is repositioned to the retracted position, and with the fixing member 60 in contact with the front wall 4A of the grain collection hopper 4, the fixing operation tool 61 is screwed into the fixing screw portion 4B of the front wall 4A. 43 is configured to be fixed to the front wall 4 </ b> A of the grain collection hopper 4. As described above, the fixing means that includes the fixing screw portion 4B, the fixing member 60, and the fixing operation tool 61 and fixes the auxiliary column 43 to the body side at the storage position is configured. In this case, since the fixing member 60 and the fixing operation tool 61 are also used as a fixing means for fixing the auxiliary column 43 to the machine body side at the work position, the structure of the fixing means can be simplified.

  The swing range of the canopy 10 around the vertical axis P1 is regulated by the auxiliary support 43 coming into contact with the grain collection hopper 4 and is within the range of the tip rotation locus shown by the two-dot chain line in FIG. The canopy 10 is configured to swing. As a result, the auxiliary support column 43 functions as a regulating member that controls the rotation of the support column 40 to the inside of the machine body. For example, the canopy 10 rotates to the inside of the machine body and interferes with the precleaner 35 and is damaged. It can prevent (refer FIGS. 1-3). For example, in the case where the canopy 10 is configured without the auxiliary column 43, a restriction that restricts the rotation of the column 40 to the inside of the machine body separately from the auxiliary column 43 (or instead of the auxiliary column 43). A member may be provided.

  By operating the operation tool 54 to the release position and removing the fixed operation tool 61, the support column 40 can be rotated around the vertical axis P1. Then, the canopy 10 is repositioned to the work position, the operation tool 54 is operated to the fixed position, and the fixed operation tool 61 is tightened, whereby the canopy 10 can be fixed at the work position, and the canopy 10 is repositioned to the storage position. The canopy 10 can be fixed at the retracted position by operating the operation tool 54 to the fixed position and tightening the fixed operation tool 61.

  For example, when the column 40 is fixed to the column support member 47 only by the operation tool 54, due to a dimensional error between the operation tool 54, the positioning fixing holes 40b and 40c of the column 40, and the column fixing hole 47a of the column support member 47, etc. There is a risk that the column 40 will rattle. However, by tightening and fixing the auxiliary column 43 side from the front by the fixing operation tool 61, it is possible to effectively prevent the column 40 from rattling, and to reliably prevent the canopy 10 from shaking at the working position and the storage position.

  Further, at the working position and the retracted position of the canopy 10, the support column 40 is fixed to the grain collection hopper 4 side at two locations, the position of the support column 40 and the position of the auxiliary support column 43, by the operation tool 54 and the fixed operation tool 61. Therefore, the support column 40 can be firmly fixed to the grain collection hopper 4 side. Thus, for example, even when a relatively large bending force is applied to the support column 40 by the operator operating the front or rear handles 73 and 74 mounted on the roof member 70 described later, the support column 40. Can be firmly supported at two locations, ie, the position of the support column 40 and the position of the auxiliary support column 43.

  Although not shown, the fixing means may be configured so that the auxiliary column 43 is fixed to the body side only at the storage position, and the fixing unit is set so that the auxiliary column 43 is fixed to the body side only at the working position. It may be configured.

  As shown in FIGS. 6 and 7, the roof member 70 includes a roof frame 71, a roof panel 72, and an inclination angle adjustment mechanism 80.

  The roof frame 71 is formed in a U-shape that is opened rearward in a plan view by a round pipe material, and a rear portion thereof is connected by a support frame 71a made of a round pipe. A plurality of vertical through holes are formed in the roof frame 71, and a roof panel 72 described later is fastened and fixed to the plurality of through holes.

  The roof panel 72 is made of lightweight resin and is integrally formed by press molding or injection molding, and the front portion and the left and right side portions thereof are formed in a shape that is curved or bent downward. Different materials may be adopted as the material of the roof panel 72. For example, the roof panel 72 may be made of a metal material (for example, a steel plate or an aluminum plate) or a reinforced resin such as FRP.

  The roof panel 72 is formed of a resin colored in a color that does not easily transmit sunlight, and is configured so that the sunlight shining from above the operation unit 5 can be sufficiently blocked by the roof panel 72. The roof panel 72 is formed with a plurality of through holes that are directed upward and downward, and the roof panel 72 is fastened and fixed to the roof frame 71 through the plurality of through holes.

  The shape of the roof panel 72 in plan view is formed in a vertically long rectangular shape that is long in the front-rear direction so that the front end of the roof panel 72 is positioned in front of the front end of the front operation panel 29 at the working position of the canopy 10. It is arranged. Thereby, at the working position of the canopy 10, the roof panel 72 can cover the driver seat 31, the fuel tank 32, the front operation panel 29, and a part of the side operation panel 30 from above in a wide range. It is configured. Different shapes (horizontal rectangular shape, vertical or horizontal elliptical shape, square shape, circular shape, etc.) may be adopted as the shape of the roof panel 72 in plan view, and the roof panel 72 is at the work position of the canopy 10. You may set the range of the operation part 5 covered by wide or narrow.

  A front handle 73 is provided on the left front portion of the roof frame 71, and a rear handle 74 is provided at a position diagonally opposite to the front handle 73 on the right rear portion of the roof frame 71 in plan view. . The front and rear handles 73 and 74 are formed of round bars and are fixed to the roof frame 71. Thereby, for example, when the inclination angle of the roof member 70 is changed by the inclination angle adjusting mechanism 80, or when the canopy 10 is changed between the working position and the storage position, for example, the front and rear handles 73, 74 are used. By operating the roof member 70 via the roof member 70, the roof member 70 can be stably held and held, and the roof panel 72 made of resin can be prevented from being damaged.

  As shown in FIGS. 9 to 11, left and right through holes are formed at the distal ends of the left and right support frames 41 a of the connection frame 41, and the inner surfaces of the distal ends of the left and right support frames 41 a are described later. The left and right guide members 81 are fixed to each other to constitute the tilt angle adjusting mechanism 80.

  A support bracket 75 extending downward from the support frame 71a is fixed to the support frame 71a of the roof frame 71. The support bracket 75 is fitted in and fixed to the vertical plate-like left and right plate-like members 76 fixed to the left and right sides of the support frame 71 a and through holes formed in the lower portions of the left and right plate-like members 76. In addition, a long circular pipe-like connecting pipe 77 is provided on the left and right.

  The connection pipe 77 of the support bracket 75 is inserted between the left and right guide members 81 fixed to the inner surface side of the left and right support frames 41a, and the left and right support frames 41a are connected to the left and right support frames 41a by a round pipe support shaft 78. It is supported so as to be rotatable around the axis P2 in the direction. As a result, the roof member 70 is supported so as to be rotatable about the left and right axial center P <b> 2 above the support column 40.

  Next, the inclination angle adjusting mechanism 80 provided over the upper portion of the support column 40 and the rear portion of the roof member 70 will be described. The tilt angle adjusting mechanism 80 includes left and right guide members 81 fixed to the front ends of the left and right support frames 41a, an tilt angle adjusting tool 83, and an elastic spring 89.

  In the left and right guide members 81, a plurality of engaging grooves 81a are formed at predetermined angles around the axis P2 in the left-right direction, whereby the inclination angle of the roof member 70 is changed and adjusted for each predetermined angle. It is configured to be able to. In addition, the left and right guide members 81 are formed with guide grooves 81b located on the circumference centered on the left-right axis P2.

  A support shaft 82 is supported on the front upper portions of the left and right plate-like members 76 in the support bracket 75 so as to be rotatable about a left-right axis P3, and an inclination angle adjusting tool 83 is supported on the support shaft 82. It is supported rotatably. As a result, the tilt angle adjuster 83 is supported by the plate-like member 76 so as to be swingable back and forth around the left and right axis P3.

  The tilt angle adjuster 83 includes a rod 84 formed of a round bar, a left arm member 85 fixed to the left end portion of the rod 84, and a right arm member 86 fixed to the right end portion of the rod 84. Configured. The right arm member 86 extends downward from the left arm member 85, and a resin grip 83a is externally attached to the lower end of the right arm member 86.

  A flat plate-like front support plate 87 is fixed to the front side of the central portion of the right arm member 86 of the tilt angle adjuster 83, and a flat plate shape protruding forward on the right side portion of the connection pipe 77 in the support bracket 75. A rear support plate 88 is fixed, and an elastic spring 89 is mounted across the front support plate 87 and the rear support plate 88. The elastic spring 89 is constituted by a tension spring, and the inclination angle adjuster 83 is urged rearward by the elastic spring 89.

  The inclination angle adjuster 83 is swung forward about the left and right axis P3 against the urging force of the elastic spring 89 to release the engagement of the rod 84 with the engagement groove 81a, and the roof member 70 is moved. The tilt angle of the roof member 70 can be changed and adjusted stepwise by swinging up and down around the left and right axis P2. In this case, in a state where the rod 84 is engaged with the engagement groove 81a, the rod 84 does not reach the back end (rear end) of the engagement groove 81a and contacts the front and rear central portions of the engagement groove 81a without any gap. It is configured as follows.

  Accordingly, the tilt angle adjusting tool 83 is swung forward to change the tilt angle of the roof member 70 while changing the tilt angle of the roof member 70 while bringing the rod 84 into contact with the guide grooves 81b formed on the left and right guide members 81, thereby moving the rod 84 to the left and right. The weight of the roof member 70 acting around the axis P2 can be easily supported by pushing the tilt angle adjuster 83 forward, and the tilt angle of the roof member 70 can be easily changed.

  Further, at the position where the angle of the roof member 70 is adjusted, the tilt angle adjuster 83 is swung backward while being assisted by the biasing force of the elastic spring 89, and the rod 84 is engaged with the engagement groove 81a. The position where the inclination angle of the roof member 70 is changed can be maintained. In this case, the biasing force of the elastic spring 89 is set so as to act even when the rod 84 is engaged with the engagement groove 81a, so that the position where the inclination angle of the roof member 70 is changed can be reliably held. For example, it is possible to prevent the engagement of the rod 84 with the engagement groove 81a due to vibration during traveling or the like.

[Operation status of canopy]
The operation status of the canopy 10 will be described with reference to FIGS. First, the position change situation of the canopy 10 will be described with reference to FIGS. As shown in FIGS. 3 to 5, in a state where the canopy 10 is repositioned to the working position, the operation tool 54 is operated to the fixed position and the fixed operation tool 61 is fixed, the fixed operation tool 61 is removed and the operation tool 54 is moved. The position is changed to the release position, the support column 40 is operated to be rotatable, and the canopy 10 is swung rightward and rearward to move backward. In this case, the surface of the fixing member 60 fixed to the lower portion of the auxiliary column 43 contacts the front wall 4A of the grain collection hopper 4, and the position of the canopy 10 in the front-rear direction is the front-rear direction in the retracted position. The position (the position where the canopy 10 has moved above the grain collection hopper 4) is positioned (the direction in which the positioning fixing holes 40b and 40c of the support column 40 face and the direction in which the support fixing hole 47a of the support member 47 faces). Match).

  Then, the front or rear handles 73 and 74 are grasped and the canopy 10 is pulled down against the biasing force of the elastic spring 50 to change the position of the canopy 10 to the retracted position. In this case, the stopper portion 40a formed on the support column 40 comes into contact with the upper surface side of the connecting member 51, and the position of the canopy 10 in the vertical direction is positioned at the vertical position of the storage position (of the support column 40). The height of the positioning fixing hole 40b substantially matches the height of the support fixing hole 47a of the support supporting member 47, and the height of the through hole of the fixing member 60 approximately matches the height of the fixing screw portion 4B of the front wall 4A. ).

  The position in the front-rear direction and the vertical direction is positioned by the fixing member 60 and the stopper portion 40a, and the canopy 10 is positioned at the storage position. At this position, the operation tool 54 is operated to the fixed position, and the fixed operation tool 61 is operated. By tightening, the canopy 10 can be fixed at the retracted position. Thereby, the position change from the work position of the canopy 10 to the storage position can be performed easily and quickly, and the workability of the position change work of the canopy 10 can be improved.

  On the other hand, in a state where the canopy 10 is repositioned to the storage position, the operation tool 54 is operated to the fixed position and the fixed operation tool 61 is fixed, the fixed operation tool 61 is removed and the operation tool 54 is repositioned to the release position. The support column 40 is operated so as to be rotatable, and the canopy 10 is swung to the right and moved forward. In this case, when the fixed operation tool 61 is removed and the position of the operation tool 54 is changed to the release position, the urging force of the elastic spring 50 acts, and the canopy 10 is assisted by the urging force of the elastic spring 50 (auxiliary mechanism). The position of the canopy 10 in the up-and-down direction is automatically positioned to the position in the up-and-down direction at the work position (the height of the positioning fixing hole 40c of the support column 40 is the height of the support column 47 of the support column 47). The height of the through hole of the fixing member 60 is substantially the same as the height of the through hole of the frame member 59).

  In addition, even if the canopy 10 is not lifted by hand, the biasing force of the elastic spring 50 may be set relatively strong so that the elastic spring 50 (auxiliary mechanism) can be completely raised to the height of the work position. The biasing force of the elastic spring 50 may be set to be relatively weak so that the height is raised to an intermediate height between the storage position and the work position by 50 (auxiliary mechanism).

  When the canopy 10 is moved forward, the surface of the fixing member 60 fixed to the lower portion of the auxiliary support 43 contacts the frame member 59, and the position of the canopy 10 in the front-rear direction is the front-rear direction at the work position. It is positioned at the position.

  The position in the front-rear direction and the vertical direction is positioned by the fixing member 61 and the elastic spring 50, and the canopy 10 is positioned at the work position. At this position, the operation tool 54 is operated to the fixed position, and the fixed operation tool 61 is operated. By tightening, the canopy 10 can be fixed at the work position. Thereby, the position change from the storage position of the canopy 10 to the work position can be performed easily and quickly, and the workability of the position change work of the canopy 10 can be improved.

  Further, when the canopy 10 is moved from the retracted position to the working position, the canopy 10 automatically rises with the aid of the urging force of the elastic spring 50, so that it is not necessary to lift the canopy 10 upward. In addition to facilitating positioning in the vertical direction, the burden on the operator when changing the position can be reduced, and the workability of the position changing operation of the canopy 10 can be further improved.

  In a state where the canopy 10 is repositioned to the work position, the operation tool 54 is operated to the fixed position and the fixed operation tool 61 is fixed, the fixed operation tool 61 is removed and the operation tool 54 is repositioned to the release position. The canopy 10 is lowered by grasping the front or rear handles 73 and 74 and pulling down the canopy 10 against the biasing force of the elastic spring 50 without rotating the canopy. And the stopper part 40a formed in the support | pillar 40 contact | connects the upper surface side of the connection member 51, and the height of the positioning fixing hole 40b of the support | pillar 40 substantially corresponded with the height of the support | pillar fixing hole 47a of the support | pillar support member 47 Then, the position of the operation tool 54 is changed to the fixed position.

  As a result, the height of the roof member 70 can be changed and adjusted separately from the height adjustment by the inclination angle change adjustment mechanism 80 in a state where the roof member 70 is positioned above the operation unit 5, and the roof member 70 is lifted up. The canopy 10 can be repositioned between the position (work position) and the lowered position where the roof member 70 is lowered. As a result, for example, when the combine is stored in a warehouse or when the combine is loaded on a truck bed, the roof member 70 can be moved to the lowered position without changing the roof member 70 to the retracted position. Combine height can be kept low.

  Note that a plurality of positioning fixing holes (or vertically long slots) may be formed in the support column 40 in the vertical direction so that the height of the roof member 70 can be changed stepwise (or steplessly). Good. In this case, a plurality of front and rear through holes (or vertically long holes) are formed in the fixing member 60, and the operation tool 54 and the plurality of positions at which the column 40 is moved in the vertical direction with respect to the column support member 47. You may comprise so that the support | pillar 40 and the auxiliary | assistant support | pillar 43 can be fixed with several different height with the fixed operation tool 61. FIG.

  Next, the change state of the inclination angle of the roof member 70 by the inclination angle adjusting mechanism 80 will be described with reference to FIGS. As shown in FIGS. 4 and 6, the front or rear handle 73, 74 is held with one hand to support the roof member 70, and the tilt angle is adjusted with the hand opposite to the one holding the front or rear handle 73, 74. The tilt angle adjusting mechanism 80 is operated by swinging the tool 83. As a result, the roof member 70 swings up and down around the left-right axis P2, and the inclination angle of the roof member 70 can be changed by a predetermined angle.

  When the inclination angle of the roof member 70 is changed by the inclination angle adjusting mechanism 80, the overhead space of the operator when the operator sitting on the driver seat 31 stands on the deck surface of the driver frame 27 is changed. It becomes. Accordingly, the height of the roof member 70 (the overhead space of the worker) is changed by changing the inclination angle of the roof member 70 according to the height of the worker, etc. A driving part space can be formed.

  Further, the roof member 70 is moved to the lowered position, and the tilt angle adjusting mechanism 80 changes the tilt angle of the roof member 70 so that the roof member 70 is tilted forward and tilted. For example, the combine is stored in a warehouse or the like. In such a case, or when the combine is loaded on a truck bed or the like, the roof member 70 can be positioned at a position that is less likely to get in the way.

  Note that different configurations may be adopted as the angle of the roof member that is changed in stages by the inclination angle adjusting mechanism 80 and the number of steps that are changed in stages, and the inclination angle of the roof member 70 is changed by the inclination angle adjusting mechanism 80. May be configured so that it can be changed and adjusted steplessly.

[First Alternative Embodiment of the Invention]
In the above-mentioned [Best Mode for Carrying Out the Invention], an example in which the grain collection hopper 4 as an example of the grain collection unit is disposed has been shown. However, as shown in FIGS. The same applies to a combine equipped with a tank 90. FIG. 12 is an overall right side view of the ordinary combine according to this another embodiment, and FIG. 13 is a front view illustrating a support structure for the canopy 10 according to this another embodiment. The configurations other than those described below are the same as those described in [Best Mode for Carrying Out the Invention].

  As shown in FIG. 12, a Glen tank 90 for storing the grains supplied from the threshing device 3 is disposed at the rear of the machine body 2 and behind the operation unit 5. The threshing device 3 is arranged side by side with the Glen tank 90 on the left and right.

  An unloader 91 for discharging the grain out of the machine from the grain tank 90 is provided at the rear of the grain tank 90. The unloader 91 is equipped with a hydraulic cylinder and a turning motor (not shown), and is configured so that the unloader 91 can be raised by the hydraulic cylinder, and the unloader 91 can be turned by the turning motor.

  The unloader 91 when not in use as shown by the solid line in FIG. 12 is diagonally arranged in plan view from the rear part of the Glen tank 90 (the rear right side part of the machine body 2) toward the front left side part of the machine body 2. It is configured as follows.

  As shown by a two-dot chain line in FIG. 12, when the canopy 10 is repositioned to the lowered position, the unloader 91 can be swung without causing the unloader 91 and the canopy 10 to interfere with each other without raising the unloader 91 so much. . Thereby, the workability | operativity of the discharge | emission operation | work of the grain by the unloader 91 can be improved by changing the position of the canopy 10 to the lowered position at the time of the discharge of the grain.

  In addition, the canopy 10 is moved from the working position to the retracted position after the forward tilt angle of the canopy 10 is changed by operating the tilt angle adjusting mechanism 80 so that the front end portion of the canopy 10 at the working position moves upward. To do. As a result, as shown by a two-dot chain line in FIG. 12, the upper surface side of the canopy 10 at the storage position is slightly inclined rearward and upward, and the height of the rear end portion of the canopy 10 at the storage position is positioned upward. Can be made. As a result, it is possible to prevent the rear end portion of the canopy 10 at the storage position from interfering with the unloader 91 and the like disposed at the rear portion of the Glen tank 90.

  As shown in FIG. 13, the support column support member 47 is fastened and fixed to the front wall 90 </ b> A of the Glen tank 90 via a bracket 93 with a plurality of bolts.

  A bracket 94 is fixed to the upper end portion of the support column support member 47, and an operation tool 54 is attached to the bracket 94 via a stopper 55 and an elastic spring 56. The operation tool 54 is biased to the support column support member 47 side (left side) by an elastic spring 56.

  Inside the support column support member 47 on the upper side of the spring support member 48, two elastic springs 50 formed of compression springs are internally arranged via an intermediate support member 95. The elastic spring 50 is composed of a compression spring, a lower part of the lower elastic spring 50 is supported by a spring support member 48, and an upper part of the upper elastic spring 50 is fixed to the lower end of the support column 40. 42.

  Since the canopy 10 is fixed to the front wall 90A of the Glen tank 90 only by the bracket 93, for example, when the assembled canopy 10 is attached to and detached from the fuselage, the bracket 93 portion is attached to the front wall 90A of the Glen tank 90. By tightening and fixing, the canopy 10 can be easily attached to the machine body side. For example, by loosening the bolt and removing the bracket 93, the entire canopy 10 can be easily removed from the machine body side (the canopy 10 as a unit). It can be easily attached to and detached from the attachment type).

  Further, since the processing on the front wall 90A side of the Glen tank 90 for attaching the bracket 93 is less, the canopy 10 can be mounted without greatly changing the structure on the machine body side (for example, the Glen tank 90). It can be installed with a slight design change on the side or a slight modification on the aircraft side). Thereby, while being able to comprise the support part of the canopy 10 more compactly, design and manufacture of the canopy 10 become still easier, and manufacturing cost can be reduced further.

  In the above-mentioned [Best Mode for Carrying Out the Invention], the combine adopting the grain collection hopper 4 as the grain collection unit may adopt the support structure of the canopy 10 in this another embodiment. In the combine which employ | adopts the grain tank 90 as a grain collection | recovery part in this another embodiment, you may employ | adopt the support structure of the canopy 10 in the above-mentioned [Best Mode for Carrying Out the Invention].
