Further, the slat 29 formed in a substantially コ shape is provided so as to be bridged in the front-rear direction at a predetermined interval between the left slat chain 28A and the right slat chain 28B. This enables the grain stalks conveyed from the grain feeding screw 3C to the feeding chamber 3D to be efficiently conveyed to the threshing device. In this specification, the left plate link chain 28A and the right plate link chain 28B are collectively referred to as a plate link chain 28.
As shown in fig. 8 and 9, a dust suction fan 40 is provided at the right front portion of the upper wall of the housing 10. Accordingly, when the feeding chamber 3D is raised to the standby position, the dust suction fan 40 can move upward relative to the side plate 5B of the manipulator 5 in a side view, so that dust scattered in the manipulator 5 can be sucked by the dust suction fan 40 and discharged to the outside of the manipulator 5, and air in the manipulator 5 can be sucked and convected to discharge hot air in the manipulator 5 to the outside.
The dust suction fan 40 is supported by a fixing member 50, and the fixing member 50 is detachably fixed to a plate 30 provided to cover a front portion of the upper wall of the housing 10.
In a front view, the plate 30 is formed into a substantially コ -shaped configuration with an opening on the lower side, and a left leg extending in the vertical direction of the plate 30 is detachably fixed to the left wall of the frame 10, and a right leg extending in the vertical direction of the plate 30 is detachably fixed to the right wall of the frame 10.
The mount 50 includes a rectangular fixing portion 51 detachably attached to the upper surface of the plate 30, a column portion 52 formed at the right portion of the upper surface of the fixing portion 51 and extending in the vertical direction, and a cylindrical tube portion 53 formed at the upper portion of the column portion 52 and extending in the horizontal direction.
The pillar portion 52 is formed in a transverse cross-sectional shape in a substantially コ shape with a left side opening. This makes the pillar portion 52 lightweight and highly rigid, and prevents deformation of the pillar portion 52.
In the front view, the lower portion of the pillar portion 52 is formed to be inclined downward to the left, i.e., to extend in the left direction as it goes to the lower side. In addition, the fixing portion 51 and the lower portion of the column portion 52 are connected by a substantially triangular rib 54 in a side view. This increases the rigidity of the lower portion of the pillar portion 52, and can further prevent the lower portion of the pillar portion 52 from deforming.
A support shaft 55 extending in the left-right direction for rotatably supporting a tension arm 46 described later is provided at a right vertical intermediate portion of the column portion 52.
A circular plate 57 that detachably fixes a fan cover 56 covering the outer periphery of the dust suction fan 40 is provided on the left portion of the cylindrical portion 53, and a support portion 58 that supports a belt cover 48 described later is provided on the right portion of the cylindrical portion 53.
The fan cover 56 is formed of a cylindrical box portion 56A, a circular attachment portion 56B provided at the right end of the box portion 56A, and 3 arm portions 56C connecting the attachment portion 56B and the box portion 56A.
The diameter of the plate 57 of the fixing member 50 and the diameter of the mounting portion 56B of the fan cover 56 are formed smaller than the diameter of the base of the circular shape on which the blades of the dust suction fan 40 stand radially. This prevents the plate 57 and the like from being an obstacle, and prevents the dust collection efficiency of the dust collection fan 40 from being lowered.
In the left side view, the pillar portion 52 of the mount 50 and 1 arm portion 56C of the fan cover 56 are provided at opposing positions. This prevents the column 52 from being an obstacle, and thus prevents the dust collection efficiency of the dust collection fan 40 from being further reduced.
The base of the dust suction fan 40 is detachably fixed to a left portion of a rotary shaft (a "second rotary shaft" in the present embodiment) 41 extending in the left-right direction. The rotary shaft 41 is rotatably fitted into the cylindrical portion 53 via a bearing 42.
A pulley (a "first pulley" in the embodiment) 43 is supported on the right portion of the rotary shaft 13 provided in the feeding chamber 3D, a pulley (a "second pulley" in the embodiment) 44 is supported on the right portion of the rotary shaft 41, and a belt 45 is wound around the pulley 43 and the pulley 44. This allows the output rotation of the engine to be transmitted to the dust collection fan 50 via the rotary shaft 13, the belt 45, and the like, thereby rotating the dust collection fan 40.
The tension of the belt 45 is adjusted to a predetermined tension by the tension arm 46. The tension arm 46 is formed of an arm 46A whose base is rotatably supported by a support shaft 55 and a pulley 46B rotatably supported by the tip end of the arm 46A.
The pulley 46B of the tension arm 46 is pressed against the belt 45 by a biasing mechanism 47 such as a coil spring attached to the support shaft 55. The upper end of the urging mechanism 47 is engaged with the cylindrical portion 53, and the lower end of the urging mechanism 47 is engaged with the arm 46A. This maintains the tension of the belt 45 at an appropriate level, and prevents the belt 45 from slipping off the pulley 44 or the like.
A belt cover 48 for covering the pulleys 43 and 44 and the belt 45 from the right side is provided on the right side of the belt 45, i.e., on the side of the operating section 5. This prevents the operator from releasing the belt 45 and the like, thereby improving safety. The upper portion of the belt cover 48 is supported by a support portion 58 provided on the tube portion 53.
As shown in fig. 10, the base of the arm 46A of the tension arm 46 is rotatably fitted around the cylindrical portion 53, and the movement in the left-right direction can be restricted by providing fixing rings 59 such as C-rings on both sides of the base of the arm 46A. This eliminates the need to separately form a member for supporting the arm 46A of the tension arm 46, and thus reduces the number of components.
