BEST MODE FOR CARRYING OUT THE INVENTION

Next, embodiments of the invention will be described.

FIG. 1 is a side view showing the overall structure of a connoin according to an embodiment of the present invention, and FIG. 2 is the same. FIG. 3 is a plan view of a side column according to the present invention. 4 is a perspective view, and FIG. 5 is a perspective view from another angle.

First, the overall configuration of the combine will be described with reference to FIGS. 1 and 2. In order to make the explanation easier to understand, the traveling direction of combine 1 will be described as the front side.

As shown in Figs. 1 and 2, the combine 1 supports the fuselage frame 2 with the left and right crawler type traveling devices 3 and 3 and drives both crawler type traveling devices 3 and 3 with the engine mounted on the fuselage frame 2. Thus, the vehicle can be moved forward or backward. At the front of the fuselage frame 2, there is a reaping part 4 that cuts and transports the grain husks and transports them to the rear of the craft, and on the left side of the fuselage frame 2, the threshing that threshs the chopped grains from the reaping part 4. A part 5 and a sorting part 6 for sorting the grains threshed by the threshing part 5 are arranged up and down. Behind the threshing unit 5, there is a slaughtering processing unit 7 for discharging cereals threshed by the threshing unit 5 to the outside as waste.

[0025] Further, on the right rear portion of the machine body frame 2, a drain tank 8 is provided for storing the grains conveyed by the milling cylinder from the sorting section 6, and the drain tank 8 extends above the rear force of the grain tank 8. A discharge auger 9 is provided for discharging the grains inside the machine. On the right front of the fuselage frame 2 in front of the Darren tank 8, there is an operating device with power, such as a steering handle 11 and various operation levers including a discharge clutch lever, which will be described later, and a driving operation unit 15 with a seat 19. In addition, an engine and a transmission are disposed below the operation unit 15.

Next, the side column 20 according to the present invention will be described with reference to FIGS. 3 to 5.

As shown in FIGS. 1 and 2, the side column 20 is disposed on the left side of the seat 19. As shown in FIGS. 3 to 5, the side column 20 is largely formed of a synthetic resin in which a side panel 21 and a side column side wall portion 22 are integrally formed. Here, the side panel 21 is formed in a plane, and the side column side wall portion 22 is formed in a hollow mountain shape.

[0027] The side panel 21 is a flat panel located on the right side of the upper surface of the side column 20, that is, in the vicinity of the left side of the seat 19. As shown in FIG. 2, on the side panel 21, a main transmission lever 35 ', an auxiliary transmission lever 36, an operation switching clutch lever 37, and a mowing transmission lever 38 are arranged. In FIGS. 3 to 5, the side column side wall portion 22 described later is shown. Only the guide holes 35a · 36a '37a' 38a of each operating lever 35 · 36- 37- 38 are shown for ease of application.

The main shift lever 35 is a lever that shifts the forward speed and reverse speed of the combine 1 main body. The auxiliary transmission lever 36 is a lever that switches between the work speed and the road traveling speed. The work switching clutch lever 37 is a lever for switching the drive transmission of the mowing unit 4 or the threshing unit 5 to ONZOFF. The IJ trimming shift lever 38 is a lever that shifts the cutting speed of the cutting unit 4 and carries it.

With this configuration, the operator can easily operate the operation levers 35 · 36 • 37 · 38 with the left hand. Each of these control levers 35, 36, 37, and 38 is a lever that is frequently used during the operation of the combine 1.

The side column side wall portion 22 is a side wall formed continuously in a substantially “<” shape (or L shape) in plan view on the left side and the front side of the side column 20. Further, the side column side wall portion 22 is provided with an operation switch 23, a display panel 50, and a weed basket operation lever 31, and a grip portion 24 is formed. Hereinafter, the shape of the side column side wall portion 22 will be described from the rear.

[0029] First, the weed rod operation lever 31 provided on the side column side wall portion 22 will be described. The weed rod operation lever 31 is disposed on the upper surface of the rear portion of the side column side wall portion 22. The weeding rod operating lever 31 is a lever for remotely operating the weeding rod 17 arranged in the front-rear direction at the lower left side of the cutting unit 4 to project and store it outward.

The weed ridges 17 extend obliquely outward and rearward from the lower side portions of the weed plates arranged at the left and right front ends of the cutting part 4 so that only the left side can be extended and stored. The weed ridge 17 is a device that separates the harvested rice from the uncut rice and prevents the uncut rice from being caught in the main body 1.

In the same side column side wall portion 22, a horizontal surface portion is formed on the upper surface of the rear portion, and a weed ridge guide hole 32 is opened. The weed rod operation guide hole 32 is a guide hole that guides when the weed rod operation lever 31 is operated and is hooked at a desired position. In addition, the weed tackle operation guide hole 32 is formed with a three-step notch hole for latching in this embodiment. More specifically The weed rod operation guide hole 32 has a notch shape indicating the storage position of the weed rod 17 and the three operation positions of the work position ( _a ) and the work position (b). Note that the work position (a) and the work position (b) are operating states in which the amount of overhang of the weed ridge 17 is different.

[0030] Since the side column side wall portion 22 itself is made of synthetic resin, the weed rod operation guide hole 32 has low oka IJ characteristics. For this reason, there is a possibility of breakage when the weed rod operation lever 31 is fixed or operated.

Therefore, the weeding operation guide 33 is provided inside the side column side wall 22 (see FIGS. 4 and 5). The side weed operation guide 33 can be provided inside the side column side wall 22 because it is formed in a hollow mountain shape. This weed tub operation guide 33 is made of a highly rigid material such as metal. The weed rod operation guide ₃₃ can securely fix or operate the weed tube operation lever ₃₁ .

By adopting such a configuration, an unreasonable burden of the weed rod operation lever 31 with respect to the weed rod operation guide hole 32 is avoided when the weed operation rod 31 is operated.

[0031] Conventionally, in a control line, the operation lever of each device has been arranged on the side panel 21. In recent years, the combine main body is being compacted. At the same time, however, there is a need for improved driver seat comfort and operability.

On the other hand, there are devices that always require operation during operation, and some devices that require little operation even during operation. For example, the above-mentioned weed basket is usually a device that is only operated at the start and end of work.

In the present invention, the weed paddle operating lever 31 is disposed on the upper surface of the side column side wall 22 which is in a position that is difficult to reach compared to the side panel 21. However, even in difficult-to-reach positions, the weed control lever 31 is not frequently used during operation and does not hinder the operability of the operator.

Further, the operator 1 can visually recognize the weed tub operating lever 31 naturally when viewing the left weed tub 17.

In addition, by setting only the weed paddle operating lever 31 to a high position, it is possible to prevent erroneous operation of the weed paddle operating lever 31 and the other operating levers 35, 36, 37, and 38. That is, the operability of the direction weed 17 can be improved. On the other hand, with such a configuration, the other operation levers 35, 36, 37, and 38 can be arranged on the side panel 21 with a space. For this reason, the operator does not recognize the operation levers 35 · 36-37-38 frequently during operation. In this way, the operability of combine 1 is improved.

Next, the operation panel 40 and the grip part 24 formed on the side column side wall part 22 will be described.

A through-hole 24a that is long in the front-rear direction is formed in the upper part of the middle part of the side column side wall 22 in the front-rear direction. The upper part of the through-hole 24a is used as a grip part 24. A plurality of front and rear are formed so that they are easy to grasp and do not slip. The lower side surface of the through-hole 24a is an inclined surface that descends toward the seat 19, and has a concave shape in the lateral direction over a predetermined range in plan view.

With this shape, the operator can grip the groove 24b of the gripping portion 24 by inserting his / her hand into the through-hole 24a even when supporting the body during the combine 1 operation. /!

In this way, the operability and comfort of the operator are improved. In addition, it is not necessary to manufacture a gripping part as a separate part. In this way, it is possible to reduce the component cost and manufacturing man-hour of combine 1.

[0033] On the other hand, on the inclined surface on the concave seat 19 side, an operation panel in which a saw depth automatic switch 41, a saw depth adjusting switch 42, a winker switch 43, a work light switch 44, and the like are arranged. Is provided. The operation panel 40 is provided obliquely upward so that the operator can visually recognize the seat 19 while seated on the seat 19.

With such a configuration, the operator can operate the operation switches 41, 42, 43, 44 while supporting the body with the grip portion 24. That is, it is possible to improve the handling performance of the combine 1.

On the other hand, the substantially rear half portion (left side) of the side column side wall portion 22 and the protruding portion 26 described later are formed higher than the recessed portion 25 described later.

By adopting such a configuration, it is possible to prevent dust from the harvesting unit 4 of the combine from entering the operation unit 15.

In this way, the comfortability of the operator can be improved. Side column side wall 22 On the left side, there is only a cutting part 4, and visibility is not a problem.

Further, since the display panel 50 is disposed in the overhanging portion 26, the area of the display panel 50 can be increased by forming the side column side wall portion 22 high. That is, the display panel 50 can be arranged with a large area.

In this way, the operability of the combine 1 can be improved. The front of the overhang 26 is the back of the bow I raising case (not shown), so visibility is not a problem.

Next, a description will be given of the concave portion 25 formed in the bent portion (left front upper portion or front upper corner portion) in the plan view of the side column side wall portion 22.

On the front left side of the side column 20 in the side column side wall portion 22, the height of the side column side wall portion 22 is set to be lower than the others, and the concave portion 25 is provided in front view and side view. Since the side column side wall portion 22 is formed in a hollow mountain shape in a sectional view of the synthetic resin, the concave portion 25 is formed with a gentle curve. In other words, the upper surface between the grip portion 24 and the display panel 50 disposed at the front portion of the side column side wall portion 22 is low, and the concave portion 25 that is opened in a substantially U shape is formed.

With such a configuration, the visibility in the front left down direction is improved in a state where the operator is seated on the seat 19.

That is, when the operator is seated on the seat 19, the weeding board 16 at the right end of the cutting part 4 is positioned and visible in the lower left front direction. When working with combine 1, whether or not the force at which the IJ cutting position is accurate is confirmed by whether or not the weed plate 16 at the right end of the cutting part 4 is located between the desired strips. For this reason, the visibility of the weed board 16 affects the workability of the combine 1.

That is, the operator 1 can always check the right weeding board 16 of the cutting unit 4 and the stock of the cutting cereal during the cutting operation, and can perform the accurate cutting operation. In this way, the operability of combine 1 is improved.

Next, the overhanging portion 26 at the front right end of the side column side wall portion 22 will be described.

The front portion of the side column side wall portion 22 is formed by an inclined surface that is lowered toward the seat 19 side. The side column 20 is erected on the left side of the seat 19 and the front step of the operation unit 15, and the front right end of the side column side wall 22 is the right side plate 2 of the side column 20. An overhang 26 is formed so as to protrude to the right of 8. That is, the protruding portion 26 is a portion where the side column side wall portion 22 extends from the side column 20. The display panel 50 is disposed on the front inclined surface of the entire front side of the side column side wall portion 22 including the overhang portion 26. The overhanging portion 26 has a notch in the lower right front. That is, the space below the overhang 26 is a space. Therefore, a foot space 27 is secured on the right front side of the side panel 21 for the operator, and the left foot does not hit the side column side wall 22.

Further, the rear surface of the overhanging portion 26 is an oblique surface extending from the side panel 21 to the right front side, as shown in FIG. 2, on the extension of the rear surface of the steering column cover 29 (see FIG. 2) in plan view. As a configuration in which the overhanging portion 26 and the steering column cover 29 are continuously arranged, the design is improved.

[0038] With such a configuration, the following effects can be obtained.

First, since the display panel 50 can be arranged on the side column side wall portion 22 including the overhang portion 26, a large area can be provided. In this way, the operability of combine 1 is improved.

Next, since the side column side wall portion 22 forms an overhang portion 26 and is cut out at the lower right front, a sufficient foot space 27 can be obtained when the operator is seated on the seat 19. For this reason, the operator 1 can obtain a sufficient living space. Even if the operator's body becomes unstable when the combine 1 turns, the foot space 27 can support the left knee. Furthermore, the left knee can be supported by the foot space 27 when the operator stands on the seat 19.

In this way, the safety and comfort of the driver's seat can be improved.

Next, color coding for each work operation system will be described.

By color-coding each work operation system, the difference in operation lever can be recognized intuitively and easily by color vision, and the operation system can also be judged by color, preventing erroneous operation of the operation lever.

[0040] As the color coding for each work operation system, the gripping portion is colored in the operation means of the combine, and the color is classified for each traveling speed change system or work operation system related to the corresponding operation means. The

Further, the gripping portion 148 of the sorting adjustment lever 152 and the indication nameplate 106g are also colored in the same color, and are the same color as the color of the gripping portion 146 of the exclusion switching lever 150 and the indication nameplate 106e. The gripping portion 147 and the instruction nameplate 106f of the auger clutch lever 151 are colored yellow.

[0047] In this way, the lever grip and indicator plate related to the travel transmission system are colored orange, the lever grip and indicator label related to the work operation system are yellow, the exhaust switch lever 150 and the selection label The control system for the multiple levers arranged intuitively and easily is colored green with the gripping part of the lever related to the adjustment operation system such as the adjustment lever 152 and the indication nameplate in green. It is possible to identify and prevent erroneous operation.

[0048] However, the position of the traveling system lever is not limited as long as it is arranged at the front part or the side part of the driving operation part, and the working system lever is provided at the left side or the front part of the driving operation part. The position of the adjustment system is not limited as long as it is arranged, and the position of the adjustment system lever is not limited as long as it is arranged on the left side of the operation control unit and behind the work system lever. . The color of the grip of the control lever and the color of the indication nameplate are not limited as long as the pilot who follows this embodiment can identify the color.

Next, a color arrangement configuration for improving maintainability will be described. This ensures that parts to be removed can be easily identified during work, so that unnecessary parts are not accidentally removed. Therefore, the following configuration can be adopted.

A tension pulley is arranged between the drive pulley and the driven pulley, and the tension pulley is used to tension the belt wound between the drive pulley and the driven pulley. When the belt is relaxed, a belt presser that keeps a gap between the drive pulley and the driven pulley and the belt properly is arranged in the vicinity of the drive pulley and the driven pulley. The color scheme is different from that of parts that do not need to be removed.

The belt presser has a different color for each tension clutch.

Then, at least one of the driving pulley, the driven pulley, the tension arm, or the tension pulley is colored according to the belt presser.

Further, the belt has a color scheme corresponding to the belt presser.

[0050] With this configuration, when replacing the belt of the tension clutch, the parts to be removed can be easily identified, and belt replacement can be performed quickly and reliably without removing unnecessary parts by mistake. It becomes. Also, when installing, the operator can improve the work efficiency without mistaken installation.

In other words, since the belt presser has a different color from the surrounding parts, it is easy to check the clearance between the pulley and the belt, which prevents the belt from being misplaced.

[0051] As shown in FIGS. 7 and 8, the belt tension clutch mechanism will be described by taking the tension clutch mechanism of the threshing clutch 242 as an example. The threshing clutch 242 is also provided on the driving force transmission path to the threshing unit with engine power.

The tension clutch is composed of a power transmission belt 253 wound between a driving pulley 251 and a driven pulley 252; a tension pulley 254; and a tension arm 260 that supports the tension pulley 254 in a rotatable manner. Yes. A belt 253 is wound between the driving pulley 251 and the driven pulley 252 and a tension pulley 254 is disposed between the driving pulley 251 and the driven pulley 252 so that the tension pulley 254 can be rotated at one end of the tension arm 260. Supported, and the other end of the tension arm 260 is pivotally supported on the aircraft side. It is linked to the threshing clutch lever 211 via a link mechanism such as a link. That is, one end of the connecting arm 261 is pivotally supported in the middle portion of the tension arm 260, and the other end of the connecting arm 261 [the rod 262, the rod 263, the arm 264, the support shaft 265, and the threshing clutch. Connected with Renoichi 211!

In such a configuration, when the threshing clutch lever 211 is rotated to the “on” side, the tension arm 260 is rotated upward via the link mechanism, and the tension pulley 254 force belt 25 3 is tensioned to drive pulley. Power is transmitted from 251 to driven pulley 252. Conversely, when the threshing clutch lever 211 is rotated to the “cut” side, the tension arm 260 is rotated downward via the link mechanism, the tension of the belt 253 by the tension pulley 254 is released, and the drive pulley is released. The power is not transmitted from 251 to the driven pulley 252. In this way, turning on and off is switched.

When the threshing clutch 242 is set to “cut”, the belt 253 is loosened. Therefore, the belt presser rod 255 and the belt presser frame 256 that are supporting members are arranged in the vicinity of the driving pulley 251 and the driven pulley 252, and the belt By the presser 255 · 256, the loosened belt 253 is configured to maintain an appropriate clearance from the driving pulley 251 or the driven pulley 252 when the clutch is disengaged.

That is, the belt pressing rod 255 is arranged on the driving pulley 251 side, and is arranged on the belt holding frame 256 force S driven pulley 252 side. Specifically, the belt holding rod 255 has a U-shape when viewed from the front, and is fixed to the inner surface of the support plate 259. The support plate 259 is fixed to the machine mechanism 290 with bolts 257 and 257 via a spacer. Is done. Then, the belt 253 is fixed so as to be positioned between the U-shaped open side of the belt presser rod 255. In other words, the belt presser rod 255 is arranged in the direction of the string of the drive pulley 251 when viewed from the side, and the both ends force bent in the perpendicular direction of the belt presser rod 255. It is arranged so as to be located on both sides of the distance. This predetermined distance is a distance shorter than the height of the belt 253 so that the belt 253 cannot release the groove force of the pulley.

Thus, when the belt 253 is wound around the driving pulley 251 and the driven pulley 252 and the belt 253 is loosened as a clutch cut state, the belt force of the driving pulley 251 is also increased by the belt pressing rod 255. I try to float evenly. The belt retainer frame 256 includes a support portion 56b having a substantially U-shaped configuration with the retainer portion 256a configured in a substantially inverted C shape when viewed from the side. The inner surface of the retainer portion 56a is slightly larger than the outer peripheral shape of the driven pulley 52. The support portion 56b is fixed to the back side of the presser portion 56a and is attached to the machine structure 91 with bolts 258 and 258. In this way, the belt pressing frame 256 is arranged outside the driven pulley 252 side of the belt 253 wound around the driven pulley 252. The belt 253 at the time of loosening is placed on the driven pulley 252 side along the belt arc. Therefore, it is configured to prevent excessive deflection.

[0053] Here, the belt 253 replacement operation will be described. The belt 253 has to be worn and deteriorated due to long-term use, and must be replaced periodically. Usually, the tension clutch is placed inside the engine room of the connoin.

When replacing the belt 253, first remove the Bonoleto 257 · 258 to which the belt presser rod 255 and the belt presser frame 256 (hereinafter referred to as “Benolet presser 255 · 256”) are attached. Remove. Next, the belt 253 is loosened (replacement is usually done when the engine is stopped and the clutch is disengaged), remove the belt 253, install a new belt 25 3 and replace the benolet presser 255 · 256 with the Bonoleto 257 · 258. And attach.

Although the replacement work itself is simple, the surrounding structure of the tension clutch 250 is complicated, and the operator may mistake the belt retainer 255 · 256 and remove other parts during replacement. In addition, the gap between the outer circumference of the belt 253 and the belt presser 255 · 256 may not be appropriate after replacement. Also, the belt retainer 255 may be accidentally attached to the inside of the belt 253, and the belt 53 may be damaged.

Here, an example will be described in detail.

Usually, the combine equipment, including pulleys 251 · 252 and belt 253, is mostly painted in black so that it is not noticeable. In this embodiment, the belt presser 255 · 256, which is likely to cause an error in removal or attachment when replacing the belt 253, is arranged in a conspicuous white color unlike other colors! As the above-mentioned belt presser, the force indicating the typical belt presser rod 255 and belt presser frame 256 and other parts that need to be removed during belt replacement work shall be colored in white.

In Fig. 7, the force shows an example of a threshing clutch 242. This also applies to all tension clutches (discharge clutch 241 and mowing clutch 243).

[0055] By making the belt pressers 255 and 256 easy to distinguish from the surroundings in this way, it is possible to prevent erroneous removal or incorrect installation when replacing the belt 253, thereby improving work efficiency. In other words, the operator can easily identify the part to be removed by recognizing it by the color rather than recognizing the part to be removed by the name or the attachment position.

Also, for the bell presser 255 · 256 white and the bell 253 black contrast 、, check the clearance tolerance of the belt 253 against the bell presser 255 • 256. The work efficiency is improved.

Furthermore, the contrast between the white of BENORET presser 255 · 256 and the black of BENORETO 253 is the same as that of BENORETO 253 force S belt presser 255 · 256. Interference is easy to detect.

Furthermore, even if the belt presser 255 is mistakenly attached to the inside of the belt 253, if both are black, it is difficult to notice the wrong attachment, but if the belt presser 255 is white, it is easy to notice. In this embodiment, the belt presser 255 · 256 is white, and the color is not limited to white as long as the color can be distinguished from the surrounding parts.

Here, the bolts 257 and 258 may be colored white at the same time. The replacement work is further simplified by unifying all the parts to be removed in white.

Alternatively, only the bolts 257 and 258 may be colored white. In this case, the effect is the same. The cost of force painting can be greatly reduced.

[0057] Further, in the second example, the belt retainer 255 · 256 of the discharge clutch 241 is white, and the belt retainer (not shown) of the threshing clutch 242 is light blue. · Belt retainer of the cutting clutch 243 (not shown) ) In a light green color. In other words, the color of the belt presser is arranged in a bright color so that it can be easily identified from the surroundings, and at the same time, each tension clutch is color-coded. Here, the colors are colors that can be contrasted with the internal devices, and are not limited to the present embodiment as long as they can be identified for each tension clutch. In this way, the parts to be removed for each tension clutch are color-coded for each tension clutch, so that when changing belts at the same time, it is possible to instantly determine which tension clutch the removed part corresponds to even when removed. Can be identified, belt replacement work The work efficiency of the industry is improved.

[0058] Further, in the third example, in addition to the second example, the drive pulley (not shown) and the driven pulley (not shown) of the discharge clutch 241 are colored white, and the drive pulley and the driven pulley of the threshing clutch 242 ( (Not shown) in light blue color · The driving pulley and driven pulley (not shown) of the mowing clutch 243 are arranged in light green color.

In this way, when replacing the belts of a plurality of tension clutches, it is possible to instantly identify the part to be removed from where the part to be removed is based on the color difference, thereby preventing an operator from making a mistake. In other words, the operator can easily replace the belt presser by simply attaching the belt presser to the tension clutch equipped with the drive pulley or driven pulley of the same color.Here, the color of the belt presser of each clutch introduced in Example 2 is used. On the other hand, the same effect can be obtained even if the tension arm or the tension pulley is color-coded corresponding to each belt presser.

[0059] Further, in the fourth example, in addition to the third example, the belt 253 of the discharge clutch 241 is white, the belt (not shown) of the threshing clutch 242 is light blue, and the belt ( Color not shown) to light green.

As described above, when replacing the belts of a plurality of tension clutches, it is possible to instantly identify the position of the replacement belt by the color, thereby preventing an operator from attaching a wrong belt. In other words, the operator can easily replace the belt by simply replacing the belt with a tension clutch having a driving pulley or a driven pulley of the same color. Further, for example, even when replacement parts are stored together, each belt can be easily identified.

[0060] This example reflects the concept of a machine that is easy for everyone to use during the maintenance of agricultural machinery. Identification of parts to be removed or parts to be removed by color so that women's 'elderly' new farmers, that is, a wide range of people, can easily work in belt replacement work that has traditionally been error-prone and time-consuming. ! / ヽ improved work efficiency when changing belts.

In addition, the above-described embodiment is a force applied to the tension clutch. In addition, it can be applied to the belt transmission section, and the work efficiency can be improved when replacing the belt.

It can be used to improve the operability of work machines including combines.
