  As shown in FIGS. 3 and 4, an instrument panel 31 for displaying the state of the combine is provided at the upper end of the instrument tower 30. The state of the combine includes, for example, the rotational speed and temperature of the engine E, the rotational speed of a transmission (not shown), the status display of the cutting unit 3 and the threshing device 5 and the like. A second accommodating portion 33 for accommodating the electrical component 32 is provided below the instrument panel 31 in the instrument tower 30. The electrical component 32 is, for example, a microcomputer, a relay circuit, a fuse, or the like. With the configuration in which the electrical components 32 are collectively accommodated in the second accommodating portion 33, for example, the electrical components 32 including the instrument panel 31 can be modularized and reduced in wiring.

  As shown in FIGS. 4 and 6, the right side wall portion 30 a of the instrument tower 30 is formed so as to be positioned on the right side of the body as it is positioned on the front side of the body in plan view. An opening 30b that can be opened is provided in the right wall 30a, and the right wall 30a is configured so that an operator can perform maintenance of the electrical component 32 from the opening 30b. The opening 30b is closed by being screwed with a flat lid member 30c.

  As shown in FIGS. 3 and 4, the left-right width of the intermediate tower 40 extends from the left end of the control tower 20 and the right end of the instrument tower 30. The upper end of the tower 20 and the upper end of the instrument tower 30 are connected without a gap. The intermediate tower 40 is formed thinner than the front-rear width of the control tower 20 and the front-rear width of the instrument tower 30. In other words, the upper rear end of the intermediate tower 40 is recessed into the front side of the airframe over the upper rear end of the control tower 20 and the upper rear end of the instrument tower 30. Thus, the intermediate tower 40 is configured so that the driver's leg knees are less likely to contact the intermediate tower 40. A third accommodating portion 42 is formed in the upper portion of the intermediate tower 40, and the third accommodating portion 42 is used for electrical wiring of an operation tool 41 (for example, a key switch 41a or a combination switch 41b such as illumination). An operation tool 41 is provided above the third housing portion 42 so as to penetrate the upper end of the intermediate tower 40. That is, the operation tool 41 is provided in a state where the base portion 41 c of the operation tool 41 enters the third housing portion 42. The size of each operation tool 41 is smaller than the size of the instrument panel 31.

  Thus, since the instrument panel 31 and the steering operation tool 21 occupy a relatively large space among the devices arranged in the front part of the operation unit 10, the configuration in which these are distributed to the left and right, The front-rear width of the tower 40 can be reduced, and as a result, the floor portion 12 can be widened.

  As shown in FIGS. 4 to 8, a front recessed portion 40 a is formed below the third accommodating portion 42 in the intermediate tower 40. The front recessed portion 40a is recessed into the front side of the machine body so as to be positioned on the front side of the machine body as it is located on the lower side in a side view. Thereby, the lower wall part 40b formed under the front recessed part 40a is located in front of the upper wall part 40c formed above the front recessed part 40a, and the lower part of the intermediate tower 40 is the intermediate tower 40. It is formed thinner than the front-rear width of the upper part of. As a result, a space S1 is formed below the front recess 40a. Thus, the space in the intermediate tower 40 is saved, and the floor 12 enters the space S1 below the intermediate tower 40 in a plan view. In addition, although the front recessed part 40a, the lower wall part 40b, and the upper wall part 40c are formed of sheet metal, they may be formed by resin molding.

  As shown in FIGS. 4 and 8, a laterally recessed portion 20 a is formed below the first accommodating portion 23 in the control tower 20. The laterally recessed portion 20a is recessed toward the right side of the body so as to be positioned on the laterally outer side of the body as it is located on the lower side in the rear view. For this reason, the lower left side wall part 20b formed below the lower end of the horizontal recessed part 20a is located more laterally outside the body than the upper left side wall part 20c formed above the upper end of the horizontal recessed part 20a. That is, the lower part of the control tower 20 is formed thinner than the left and right width of the upper part of the control tower 20. As a result, a space S2 is formed below the lateral recess 20a. As described above, the space for the control tower 20 is saved, and the floor portion 12 enters the space below the control tower 20 in plan view, that is, the space S2. In addition, although the horizontal recessed part 20a, the lower left wall part 20b, and the upper left wall part 20c are formed of sheet metal, they may be formed by resin molding.

  Thus, since the floor portion 12 enters the spaces S1 and S2 and the footrest 14 enters the spaces S1 and S2, the foot space of the driver can be widened as compared with the configuration in which the spaces S1 and S2 are not formed.

[Side panel]
As shown in FIG. 3, the side panel 50 is provided on the left side of the driver seat 11 so as to be connected to the instrument tower 30. In order to increase the area of the floor 12 as much as possible, the lateral width of the side panel 50 is set to be narrower than the lateral width of the instrument tower 30.

Within the lateral width of the side panel 50, the main transmission lever 51 is arranged at the right side and the auxiliary transmission lever 52 is arranged at the left side. That is, the main transmission lever 51 and the sub transmission lever 52 are arranged so that the distance between the main transmission lever 51 and the driver seat 11 is closer than the distance between the auxiliary transmission lever 52 and the driver seat 11. Since the main transmission lever 51 is more frequently used by the driver than the auxiliary transmission lever 52, the main transmission lever 51 is operated at a location closer to the center of the driving unit 10 by the configuration of the main transmission lever 51. Easily reachable and easy to handle.

  As shown in FIG. 9, a main transmission link mechanism 55 and an auxiliary transmission link mechanism 56 are provided inside the side panel 50. When the driver operates the main speed change lever 51, the main speed change link mechanism 55 provided in the side panel 50 causes the main speed change mechanism (not shown), which is an HST (hydrostatic continuously variable transmission), for example. The operation of the transmission lever 51 is transmitted. The main transmission lever 51 is configured to be swingable about the shaft core P1. When the driver operates the auxiliary transmission lever 52, the operation of the auxiliary transmission lever 52 is transmitted to the auxiliary transmission mechanism (not shown), which is a gear mission, for example, by the auxiliary transmission link mechanism 56 provided in the side panel 50. The A side panel frame 53 extending in the vertical direction is provided inside the side panel 50, the main transmission lever 51 is located on the right side (left side in FIG. 9) of the side panel frame 53, and the auxiliary transmission lever 52 is disposed on the side panel frame 53. Is located on the left side (right side in FIG. 9).

  The auxiliary transmission link mechanism 56 includes an auxiliary transmission lever 52 that is operated by the driver, an auxiliary interlocking rod 59 that transmits the operation of the auxiliary transmission lever 52 to the auxiliary transmission mechanism, and a relay member between the auxiliary transmission lever 52 and the auxiliary interlocking rod 59. And a second swinging arm 58. The auxiliary interlocking rod 59 is located on the right side of the machine body with respect to the main transmission lever 51. The auxiliary transmission lever 52 is configured to be swingable about the axis P2 of the counter shaft 57 as a fulcrum. The counter shaft 57 is supported at two points by a side panel frame 53 and a stay 54 fixedly welded to the side panel frame 53 while being externally fitted to the cylindrical bearing. The auxiliary transmission lever 52 is connected to the left side end of the counter shaft 57 and the second swing arm 58 is connected to the right end of the counter shaft 57. The sub transmission lever 52 and the second swing arm 58 are fixed to the counter shaft 57 so as to be swingable integrally. The auxiliary interlocking rod 59 is connected to the swing end of the second swing arm 58 through a joint.

  As described above, even when the auxiliary interlocking rod 59 is positioned on the right side of the machine body relative to the main transmission lever 51, the auxiliary transmission lever 52 is arranged at a position closer to the left side of the side panel 50 by using the counter shaft 57. be able to. As a result, the main transmission lever 51 and the auxiliary transmission lever 52 can be arranged in a compact manner, and the lateral width of the side panel 50 can be saved. As a result, the width in the left-right direction of the floor 12 is set wide, and the comfortability of the driving unit 10 is improved.

[Support structure for sunshade]
As shown in FIGS. 16 and 17, the awning member 16 provided in the operation unit 10 includes a cover frame 60 provided in a substantially rectangular shape in plan view, and the cover frame 60 at the rear of the operation unit 10. A pair of left and right support legs 61 for supporting the front wall of the grain recovery unit 6 provided.
The cover frame portion 60 is connected to the upper end portion of the support leg portion 61 via a connecting shaft 62 and an attachment angle changing mechanism 70 so that the attachment angle with respect to the support leg portion 61 can be changed.

The connecting shaft 62 includes a support hole (not shown) formed in the center portion in the front-rear direction of the connecting bracket 63 provided on both the left and right sides of the cover frame portion 60, and a boss portion 61 a provided at the upper end portion of the support leg portion 61. It penetrates. A position near the boss portion 61a at the upper portion of the support leg portion 61 is connected to each other by a horizontal member 61b.
The cover frame portion 60 is connected to the upper end portion of the support leg portion 61 by connecting the connection shaft 62 with respect to the upper end portion of the support leg 61 by appropriately using a retaining means such as a flange portion 62a or a retaining pin (not shown). It is connected so as to be able to swing around the axis P3 of 62.

The attachment angle changing mechanism 70 has a fixed state in which the swing of the cover frame 60 that is swingable about the axis P3 of the connecting shaft 62 with respect to the upper end of the support leg 61 is restricted to a specific position. Then, the position is switched to a movable state allowing the position change by swinging. As a result, the mounting posture of the cover frame portion 60 with respect to the support leg portion 61 can be changed.
The attachment angle changing mechanism 70 includes a continuously variable changer 71 that can adjust the swing of the cover frame 60 steplessly within a predetermined range and a multistage changer 72 that can be adjusted in multiple steps, each of which is a cover frame. The connecting bracket 63 provided on the portion 60 and the mounting bracket 64 provided on the upper end of the support leg 61 are provided.

As shown in FIG. 17, the continuously variable portion 71 is provided on both the left and right sides of the cover frame portion 60.
A connecting arc 63 provided in the cover frame 60 is provided with a partially arc-shaped elongated hole 63 a centering on the axis P <b> 3 of the connecting shaft 62. A jack bolt 65 with a handle that can be fastened and fixed to the mounting bracket 64 in a state of being inserted into the long hole 63 a is screwed into a welding nut 65 a provided on the mounting bracket 64.
Therefore, by loosening the fastening state of the jack bolt 65 and the welding nut 65a, the connection bracket 63 is moved relative to the jack bolt 65 within the length range of the long hole 63a, and the connection bracket 63 is attached to the support leg 61. The posture can be changed to an arbitrary angle.
Then, by screwing the jack bolt 65 into the welding nut 65 a provided in the mounting bracket 64 and tightening, the connection bracket 63 can be clamped and fixed to the mounting bracket 64 at an arbitrary position.

As shown in FIG. 17, the multistage changing portion 72 is provided on either one side (the right side in this embodiment) of the cover frame portion 60 in the left-right direction.
In the connection bracket 63, a lock pin 66 is provided at a portion opposite to the side where the elongated hole 63a is formed across the shaft core P3 of the connection shaft 62, and the lock pin 66 can be selectively engaged. A large number of positioning holes 64 a are formed in the mounting bracket 64 at a position facing the lock pin 66.
A plurality of positioning holes 64 a are formed in a state of being aligned on an arc centered on the axis P <b> 3 of the connecting shaft 62.
The lock pin 66 is urged by an urging spring 67 that urges the lock pin 66 toward the positioning hole 64 a, holds the handle 66 a of the lock pin 66, and pulls out against the urging spring 67. Thereby, it is comprised so that extraction from the positioning hole 64a is possible.

Thus, by providing both the stepless change portion 71 and the multistage change portion 72 as the attachment angle change mechanism 70, it becomes easy to change the attachment angle of the cover frame portion 60 with respect to the support leg portion 61.
In other words, in the structure having only the general multi-stage changing portion 72, the angle of the covering frame portion 60 is changed and the handle portion 66a of the lock pin 66 is gripped while the weight of the covering frame portion 60 is supported. Therefore, it is necessary to perform the insertion / removal operation.
Compared with this, since the present embodiment includes the continuously variable portion 71, the jack bolt 65 is loosely tightened to the welding nut 65a, and the cover frame portion 60 is in a state where a frictional resistance that is difficult to move with its own weight is generated. Thus, by changing the angle of the cover frame 60 little by little with a hand, it becomes easy to align the lock pin 66 with the predetermined positioning hole 64a. By tightening the jack bolt 65 after the holes of the lock pin 66 are aligned, it is possible to more reliably maintain the posture of the cover frame portion 60.

The engine E is housed in an engine bonnet 8 that also serves as a mounting table for the driver seat 11 in the driver 10 provided at the front of the machine body frame 1.

The pre-filter, the oil pump, and the filter 7A of the oil supply piping system are disposed between the threshing device 5 and the hopper-type grain recovery unit 6 arranged side by side.
Of the plurality of support legs 6a erected on the body frame 1 so as to support the hopper-type grain recovery unit 6, the filter 7A is the center side of the body most in the left-right direction and in the front-rear direction. It is attached to the support leg 6a located in the foremost position. The support legs 6a are positioned outside without entering the engine bonnet 8. As a result, the filter 7A is attached to the center side of the machine body where the possibility of contact with other objects is low and outside the engine bonnet 8 where the thermal influence of the engine E is small.

The mounting height of the filter 7C with respect to the support leg 6a is the same as a fuel supply port (not shown) in the engine E, or a height position with little difference in height. Therefore, for example, compared with the case where the position of the filter 7A is considerably lower than the height of the fuel supply port of the engine E, it is easy to reduce the possibility of engine stall.
That is, if the position of the filter 7A is considerably lower than the fuel supply port height of the engine E, the filter is suddenly increased when the load on the engine E suddenly increases and a large amount of fuel is consumed. There is a possibility that the fuel supply amount from 7A to the fuel supply port of the engine E will be insufficient and an engine stall may occur, but the mounting height of the filter 7A is the same as that of the fuel supply port in the engine E, or the height difference is small By keeping the height position, it is easy to avoid such problems.
As shown in FIG. 20, the filter 7A is detachably attached to the support leg 6a via a bracket 6b and a connecting bolt 6c attached to the support leg 6a.
