BEST MODE FOR CARRYING OUT THEINVENTION

[0011] One embodiment of the present invention will be explained with reference to the drawings, in which 1 is a combine body frame, 2 is a running device, 3 is a threshing device provided on one side above the running device 2, 4 is a harvesting device, 5 is a grain tank provided to the side of the threshing device 4, and 6 is a control unit.

[0012] The control section 6 comprises a step 10 on which the operator stands, an operator's seat 11 on which the operator sits, a front control panel 12 having switches and levers provided in front of the operator's seat 11, and a side control panel 13 having switches and levers provided to the side of the operator's seat 11 (Figure 5).

[0013] The control section 6 is configured by surrounding an operator's seat 11, a front control panel 12, and a side control panel 13 with a cabin 15.

[0014] A cabin 15 for an operator to sit in is provided on the side of the threshing device 3, an operation seat 11 is provided inside the cabin 15, a side operation panel (clutch panel) 13 is arranged on the side of the operation seat 11, a lower vertical section 16 (also called the "connection section") is formed on the threshing device 3 side (inside the aircraft) of the step section 10 of the cabin 15, a sloped section 17 is formed which slopes upward from the lower vertical section 16 toward the threshing device 3 side, an upper vertical section 18 is formed at the side end of the sloped section 17 toward the threshing device 3 (Figure 4), a brake pedal 19 (also called the "pedal") is arranged inside the lower vertical section 16 (Figure 7), and the side operation panel (and its electrical equipment) 13 is arranged to the side of the upper vertical section 18 (also called the "vertical section").

[0015] Also, a space 20 is provided between the lower surface of the side operation panel 13 and the upper surface of the inclined portion 17 (FIG. 7).

[0016] Therefore, by forming the space 20 below the side control panel 13, the interior space of the cabin 15 is expanded and the freedom of arrangement of parts is improved.

[0017] The spatial volume of the cabin 15 can be increased without changing the arrangement of the members around the cabin 15, improving the habitability of the operator in the cabin 15 and increasing the freedom of the operator's operating posture, thereby improving operability.

[0018] A side control panel 13 is provided on the upper vertical portion 18, and the side control panel 13 is configured to be detachable from the upper vertical portion 18.

[0019] The side operation panel 13 is arranged so as to be vertically rotatable.

[0020] The lower end of the upper vertical portion 18 is configured to be located lower than the lower end of the side control panel that has been rotated downward.

[0021] When the side control panel 13 is rotated upward, its front end is positioned rearward of the aircraft body relative to the front end 22 of the engine cover 21.

[0022] An opening 25 is formed in the inclined portion 17, and an opening / closing lid (opening cover) 26 is disposed thereon.

[0023] An oil inlet 27 for the HST and an oil inlet 28 for the transmission case are disposed below the inclined portion 17 (FIG. 7).

[0024] By making the upper vertical portion 18 detachable, the electrical components 30 of the side operation panel 13 can be easily removed, improving maintainability. When the side operation panel 13 is rotated upward, it is positioned rearward of the front end portion 22 of the engine cover 21, so there is nothing blocking the view above the opening / closing cover 26 of the opening 25, improving the efficiency of oiling and maintenance work.

[0025] A rear opening 32 is formed at the rear of the cabin 15, and a rear electrical case 33 is detachably arranged in the rear opening 32 (Figure 17). An engine harness 34 and various harnesses 35 for the traveling vehicle body are provided in the rear electrical case 33 and are configured to pass through the rear opening 32 and be pulled into the cabin 15, and an insulator 36 is provided at the rear of the rear electrical case 33 (Figure 21).

[0026] Since the rear electrical case 33, to which the engine harness 34 and various vehicle side harnesses 35 are attached, can be attached to the rear opening 32, the various harnesses can be attached and detached inside the cabin 15, thereby reducing the time required for disassembly and assembly work.

[0027] By providing the insulator 36 at the rear of the rear electrical case 33, engine noise and exhaust heat are less likely to be transmitted, improving work comfort and eliminating the need to install a separate insulator.

[0028] An exhaust port cover 41 of an exhaust purification device (DPF) 40 is disposed above the engine cover 21 and on the side of the threshing device 3 inside the cabin 15 (FIG. 5). The exhaust of the exhaust purification device 40 is disposed outside the cabin 15 and above the threshing device 3.

[0029] A pivoting post 43 for pivotably supporting the side control panel 13 is disposed above the outlet cover 41 (FIGS. 5 and 8).

[0030] A front control panel 12 is disposed at the front of the cabin 15, and a support lock mechanism 45 that switches whether or not to restrict rotation when the side control panel 13 is rotated to a position toward the front of the aircraft is disposed on the side of the front control panel 12 (FIG. 8).

[0031] Since the discharge port cover 41 of the exhaust purification device 40 can also be used as the mounting portion for the pivot support 43, the number of parts can be reduced.

[0032] By providing the front operation panel 12 with a support lock mechanism 45, the side operation panel 13 becomes a strength member in the rotation restricted state, so that the rigidity of the operation section 6 can be improved.

[0033] The support lock mechanism 45 allows the tilt angle to be adjusted in multiple steps or steplessly when restricting the rotation of the side operation panel 13.

[0034] In this case, it may be configured to be fixed with knob bolts 48 or the like in a plurality of positioning holes 46 in the vertical direction or in vertical adjustment holes 47 (FIG. 9).

[0035] By loosening the knob bolt 48 and removing it from the positioning hole 46 or the adjustment hole 47, the side control panel 13 can be rotated about the rotation shaft 44 as a rotation fulcrum, and the side control panel 13 can be placed in a position nearly horizontal to the ground as shown in Figure 5, or in a number of positions with the front raised and inclined at different angles. Once the position of the side control panel 13 has been decided, the knob bolt 48 is tightened to lock the rotation of the side control panel 13.

[0036] The side operation panel 13 is so configured that the upper surface 49 of the side operation panel 13 is positioned higher than the upper surface of the operator seat 11 regardless of the inclination angle of the side operation panel 13.

[0037] When restricting the rotation, the inclination angle of the side operation panel 13 can be adjusted in multiple steps or steplessly, so that the side operation panel 13 can be easily viewed by an operator and set at an angle that is easy to operate, improving operability and reducing the occurrence of erroneous operation.

[0038] Even if the inclination angle is changed to a lower angle, the upper surface 49 of the side operation panel 13 is positioned above the work seat surface, so that the operator can easily reach it and the configuration has good visibility.

[0039] A brake body (washer or the like) 52 that applies resistance to the rotating shaft 44 of the rotating support 43 is disposed (FIG. 12), and a monitor 50 is attached to the front of the side control panel 13 (FIGS. 8 and 12).

[0040] When the side operation panel 13 is rotated forward (to a horizontal position), the monitor 50 is disposed in a position overlapping with the operation seat 11 when viewed from the front and rear (FIG. 12).

[0041] By disposing the brake body 52 on the pivot shaft 44 of the pivot support 43, even if the side control panel 13 rotates forward due to contact with a worker or vibration of the aircraft when it is rotated upward during maintenance work, etc., the movement (rotation) speed of the side control panel 13 can be slowed down, preventing contact (collision) with the worker.

[0042] When the monitor 50 is provided on the side operation panel 13, the monitor 50 is positioned so as to overlap with the operation seat 11 when the side operation panel 13 is rotated toward the front of the aircraft, thereby limiting the range (distance) over which the viewpoint must be moved during operation, improving visibility and preventing erroneous operation.

[0043] An inclined portion 17 is provided on the left side of the operator's seat 11, and a space 20 is provided on the side of the reaping device 4.

[0044] This allows for an increase in the space of the cabin 15.

[0045] A lower vertical portion 16 rises from the step portion 10, and an inclined portion 17 starts at the upper portion of the lower vertical portion 16.

[0046] Therefore, the step portion 10 is left on the aircraft body side and the upper side of the step portion 10 is surrounded by the cabin 15, so that the components outside the cabin 15 are not affected.

[0047] The leftmost side of the space 20 of the cabin 15 constitutes the upper vertical portion 18.

[0048] Therefore, the step portion 10 is left on the aircraft body side, and the upper part of the step portion 10 is surrounded by the cabin 15, so that the components outside the cabin 15 are not affected.

[0049] A mounting member for a brake pedal is disposed in the lower vertical portion so as to penetrate the lower vertical portion in the intersecting direction.

[0050] Therefore, it is possible to configure the cabin 15 without changing the arrangement of the brake pedal 19 as in the conventional case.

[0051] Electrical components 30 are placed on the upper vertical portion 18 .

[0052] Therefore, the inside of the left wall portion (upper vertical portion 18) of the cabin 15 can be used as a location for arranging the electrical components 30, making effective use of the available space.

[0053] An electrical component 30 connected to the brake pedal 19 is arranged along the inclined portion 17.

[0054] Therefore, the electrical components 30 can be arranged so as not to affect both the components arranged inside and the components arranged outside the cabin 15. In addition, the electrical components 30 are arranged along the inclined portion 17, which prevents impurities such as soil and leaves from accumulating inside the cabin 15.

[0055] An HST oil filter 54 is disposed in a space formed in the lower part (below) of the inclined portion 17 (FIG. 7).

[0056] As a result, there are no parts protruding into the interior space of the cabin 15, the space 20 can be expanded further, and work can be carried out by effectively utilizing the space formed between the side control panel 13 and the lower inclined portion 17.

[0057] A transmission oil filler port 55 is disposed in a space formed in the lower part (below) of the inclined portion 17 at a position separate from the above-mentioned HST oil filter 54 (FIG. 7).

[0058] As a result, there are no parts protruding into the interior space of the cabin 15, the space 20 can be expanded further, and work can be carried out by effectively utilizing the space formed between the side control panel 13 and the lower inclined portion 17.

[0059] An opening 25 is provided between the lower vertical portion 16 and the inclined portion 17. If the opening 25 is always open, exhaust gas and foreign matter will enter from outside the machine, so it is desirable to have a structure in which this opening 25 can be closed with a lid member (not shown) when it is not required for operation.

[0060] Therefore, since an opening 25 is provided between the lower vertical portion 16 and the inclined portion 17, maintenance of components such as the HST oil filter 54 and the transmission oil filler port 55 which are provided on the outside of the cabin 15 can be performed from inside the cabin 15 through the opening 25, making maintenance work easy.

[0061] A rotatable side control panel 13 is provided between the lower vertical portion 16 and the upper vertical portion 18.

[0062] By making the side operation panel 13 rotatable, maintenance of the side operation panel 13 and the parts concealed by the side operation panel 13 can be performed more easily, and the side operation panel 13 can also be assembled and attached easily.

[0063] An electrical component 30 is disposed between the side control panel 13 and the upper vertical portion 18.

[0064] Therefore, by making the side control panel 13 rotatable, the space between the left side of the side control panel 13 and the upper vertical portion 18, which was previously unavailable, can now be utilized on the back side (left side) of the side control panel 13 to arrange electrical components 30, making it possible to effectively utilize the space.

[0065] A space 20 is formed between the lower surface of the side control panel 13 and the upper surface of the inclined portion 17 by hollowing out to the left side, and a part of the space 20 is used as a space for arranging a part of the electrical components 30.

[0066] Therefore, the installation space for the electrical components 30 can be secured without affecting the interior space of the cabin 15.

[0067] An electric component cover 31 is provided on the right side of the electric component 30, and the electric component cover 31 is configured to cover the electric component 30 up to a lower position on the right side of the electric component 30.

[0068] Therefore, the electrical component cover 31 prevents interference with the electrical components 30, ensuring stable operation.

[0069] The electrical equipment cover 31 is provided within the vertical width (range) of the upper vertical portion 18 at the left end of the cabin 15.

[0070] Therefore, the size of the service hole opening for the filter, etc. is not sacrificed.

[0071] When the side operation panel 13 is rotated to an upright state, it is configured to rotate to a position rearward beyond the front upright portion 56 of the engine cover 21.

[0072] In other words, when the side control panel 13 is in the upright position, the lower surface of the side control panel 13 becomes the front surface, and the position of the front surface of this side control panel 13 is located rearward of the front upright portion 56 of the engine cover 21 in a side view.

[0073] Therefore, when the side operating panel 13 is rotated upward, the side operating panel 13 is not positioned above the opening 25 of the inclined surface inclination portion 17, improving maintainability.In addition, it is also possible to open the left side window glass (not shown) of the cabin 15 to access the harvesting device 4, etc., further improving maintainability.

[0074] The rear electrical equipment case 33 is configured as a separate part from the cabin 15.

[0075] For this reason, in the past, the electrical equipment case was configured as one unit with the operator's seat 11, which resulted in a complicated installation configuration and reduced production efficiency. However, in the present invention, the rear electrical equipment case 33 is configured as a separate part from the cabin 15, which makes installation and assembly easier.

[0076] The rear electrical equipment case 33 is configured to be attached from the rear of the cabin 15.

[0077] Therefore, the installation work can be easily performed since it is installed from the open area at the rear of the cabin 15.

[0078] A rotatable side control panel 13 is provided in front of a removable rear electrical equipment case 33.

[0079] Therefore, space can be secured by rotating the side operation panel 13, and the side operation panel 13 can also be mounted from the rear, so even more space can be secured.

[0080] Even after the side operation panel 13 is rotated, the side operation panel 13 is disposed in front of the rear electrical equipment case 33.

[0081] Therefore, the harness coming out from the rear electrical equipment case 33 is also routed to the side operation panel 13, making the harness route natural and facilitating assembly and connection work.

[0082] The lower surface of the rear opening 32 formed in the cabin 15 is configured to be at approximately the same height as the lower end of the side control panel 13 when it is rotated upwardly about the rotation shaft 44 as a rotation fulcrum.

[0083] As a result, the rear opening 32 and the rear side of the side operation panel 13 are positioned close to each other, so that even when the side operation panel 13 is rotated, the harness is not subjected to stretching or shrinking forces, and the harness can be routed smoothly.

[0084] A harness 35 which runs from a removable rear electrical equipment case 33 into the cabin 15 is provided on the left side of the fuselage.

[0085] Therefore, harness 35 passes through the left side of the fuselage, making it possible to route it without any difficulty.

[0086] The lead-in portion 60 of the harness 35 is formed by a separate plate 61, and the harness 35 is configured to have a grommet 62 fixed thereto.

[0087] The inside of the rear electrical equipment case 33 is originally sealed to a certain extent from the outside, but by separating it from the inside of the cabin 15, it is possible to block the intrusion of dust and engine noise from the outside.

[0088] The rear opening 32 of the cabin 15 is positioned offset to the left side of the rear panel 64.

[0089] This makes it easier to construct the frame at the rear right side.

[0090] The rear opening 32 of the cabin 15 opens to the front and top.

[0091] That is, the upper and lower middle portion of the rear panel 64 of the cabin 15 is constituted by a vertical plate 65 and a horizontal plate 66 , and the rear opening 32 is formed by being opened across the vertical plate 65 and the horizontal plate 66 .

[0092] This makes it easier to perform maintenance inside the rear electrical equipment case 33.

[0093] A seal 67 is provided around the entire periphery of the removable rear electrical equipment case 33.

[0094] By providing the seal 67 on the rear electrical case 33, the work of attaching or detaching the rear electrical case 33 can be performed simply by attaching or detaching the rear electrical case 33 and tightening the bolts, nuts, etc. required for that purpose, thereby improving the efficiency of maintenance and other work.

[0095] An insulator 36 is provided at the rear of the rear electrical equipment case 33 .

[0096] Therefore, engine noise and heat can be prevented from being transmitted into the rear electrical equipment case 33, and the work of attaching a separate insulator 36 after assembly is not required.

[0097] An outlet 68 for the engine harness 34 and the vehicle body side harness 35 is provided on the rear surface of the rear electrical case 33.

[0098] This makes it possible to prevent engine noise and heat from being transmitted into the rear electrical equipment case 33, and also makes the assembly work easier.

[0099] A seal 71 provided on a cover 70 of the rear electrical equipment case 33 seals between the grommet fixing plate 61 and the rear opening 32 of the cabin 15.

[0100] Therefore, by providing a seal 71 on the cover 70 on the cabin 15 side, it is possible to further improve the sound insulation and dustproofing properties.

[0101] The side operation panel 13 is constructed in an independent state, and the rear support of the side operation panel 13 is attached to the surface of the operation seat 11.

[0102] Therefore, the components of the side control panel 13 can be mounted in an assembled state, improving the airtightness of the cabin 15 and preventing noise.

[0103] The lower part (base) of the upwardly protruding pivot pillar 43 is attached to the seat mounting surface 73 of the engine cover 21 on which the operator's seat 11 is mounted, and the rear side of the side operation panel 13 is attached to the rear support part 74, which is the upper end part of the pivot pillar 43 (Figure 12).

[0104] Therefore, the distance from the pivot shaft 44 serving as the fulcrum to the seat mounting surface 73 serving as the fixed portion is shortened, and bending moment is less likely to be applied, thereby improving rigidity.

[0105] An exhaust purification device 40 for an engine (not shown) is disposed below the portion of the pivot support 43 that is protruded for supporting the side control panel 13.

[0106] Therefore, the discharge portion of the exhaust purification device 40 can be utilized advantageously.

[0107] The side operation panel 13 is constructed in an independent state, and the support of the front part of the side operation panel 13 is attached to the front operation panel 12 side.

[0108] Therefore, by attaching it to the front operation panel 12, the rigidity can be ensured. There is also little deviation in position.

[0109] A front support column (front support member) 77 of the side operation panel 13 is fixedly and detachably attached to a front support column 76 provided on the front operation panel 12 so as to protrude upward.

[0110] By protruding the front support pillar 76, the rigidity of the front operation panel 12 can be increased, and the rigidity of the support lock mechanism 45 can be improved.

[0111] That is, a plurality of positioning holes 46 or vertical adjustment holes 47 are provided in the front support 76 provided on the front control panel 12 side, and knob bolts 48 or the like are inserted into the positioning holes 46 or adjustment holes 47 to attach the front support 77 of the side control panel 13 in a fixed state while allowing it to be attached and detached freely.

[0112] A rotation shaft 44 is provided on the rotating support 43, and the side control panel 13 can be rotated around the rotation shaft 44 and lifted.

[0113] Therefore, the maintainability can be improved.

[0114] An adjustment hole 47 is provided in the front support pillar 76 of the support lock mechanism 45, so that the height of the front part of the side operation panel 13 can be adjusted (FIG. 9).

[0115] Therefore, by moving the front part of the side operation panel 13 up and down, the height of the HST lever (not shown) provided on the side operation panel 13 can be adjusted.

[0116] The side operation panel 13 is constructed in an independent state and includes a monitor 50 therein.

[0117] That is, the monitor 50 is attached to the side operation panel 13 side, and the monitor 50 moves together with the side operation panel 13 as one unit.

[0118] Therefore, the monitor 50 can also be moved upward during maintenance.

[0119] The monitor 50 is attached to the front support column 76 of the support lock mechanism 45 .

[0120] Therefore, by attaching the monitor 50 to the support lock mechanism 45, which serves as the front fixing portion of the side control panel 13, it is possible to minimize the shaking of the monitor 50.

[0121] The rear part of the side control panel 13 is extended rearward beyond the position of a pivot support 43 that supports the rear part of the side control panel 13.

[0122] Therefore, the rotating support column 43 is hidden by the rear of the side operation panel 13, improving the design. Hands will not come into contact with it, improving safety.

[0123] The bottom surface of the lower cover 80 of the side operation panel 13 is located above the rotation shaft 44 which serves as the rotation fulcrum of the rotation support column 43 of the side operation panel 13 (FIG. 13).

[0124] Therefore, by raising the rotation fulcrum above the rotation shaft 44, the cutout of the lower cover 80 can be minimized.

[0125] The bottom surface of the lower cover 80 of the side operation panel 13 in front of the rotation shaft 44 of the rotation fulcrum of the side operation panel 13 is disposed below the rotation shaft 44 of the rotation fulcrum.

[0126] The front part of the lower cover 80 is inflated below the rotation shaft 44, so that the contents can be configured without interfering with the rotation of the side control panel 13.

[0127] The rotation shaft 44 of the side control panel 13 configured in an independent state is disposed forward of the seat rear panel 63 of the engine cover 21 of the cabin 15.

[0128] Therefore, there is no need to form a groove for rotation in the seat rear panel 63, and the airtightness of the cabin 15 is improved.

[0129] A switch panel 81 is provided on the lower left side of the side operation panel 13, and the lower part of the switch panel 81 is cut.

[0130] Therefore, an increase in the width direction due to the draft angle of the panel can be prevented.

[0131] The electrical components 30 are arranged in the space created by the cutout 82 in the side control panel 13.

[0132] This allows for effective use of the space provided by the cut.

[0133] A brake body 52 that applies resistance to the rotation of the side operation panel 13 is provided on the rotation shaft 44 that serves as the rotation fulcrum of the side operation panel 13.

[0134] Therefore, the side operation panel 13 rotated to the upright state can be prevented from rotating forward inadvertently, and the side operation panel 13 can be configured to be rotated while being held without any backlash.

[0135] The monitor 50 attached to the rotating side operation panel 13 is disposed at a position overlapping with the operation seat 11 when viewed from the front.

[0136] Therefore, the monitor 50 can be viewed without moving the viewpoint much during operation.

[0137] An operating section 83 such as switches and levers of the side operation panel 13 configured in an independent state is disposed above the seat surface of the operator's seat 11.
