That is, the first termination case cover 36b is provided with a reference sign (3-F-A1) and a sign <1>, and the first connection case cover 37c has a sign (3-F-B1) and a sign <2>. Reference numeral 3-F-B2 and a symbol <3> are attached to the second connection case cover 37d.

Next, a configuration in which the identification of the maintenance cover itself included in the maintenance target site is increased by taking the water-receiving unit 80 shown in FIG. 15 as an example.

This water system part 80 is a site | part which connects the end part of the 1st conveyor 31 to the start end part of the grain cereal conveyor 33, and the 1st end case 36 and the connection case 37 are provided.

As described above, the water-based portion 80 is disposed on the left side of the threshing apparatus 5 (the side where the grain grain tank 7 is located), and the combine 100 with the grain grain tank 7 open. It is exposed to the outside of a gas, and becomes a state in which maintenance is possible.

One end of the screw 31a of the first conveyor 31 is disposed at the first end case 36.

To the end portion (in the grain grain conveyance direction) of the connection case 37, a start end portion (in the grain grain conveyance direction) of the grain case 33a is connected. The grain cereal case 33a is exposed to the outside of the base of the combine 100, and covers the screw 33b of the grain cereal conveyor 33. As shown in FIG.

The water terminal portion 80 is provided with a first end case cover 36b, a first connection case cover 37c, and a second connection case cover 37d. The first end case cover 36b is a cover attached to the first proximal case 36, and when the first end case cover 36b is detached from the first end case 36, the maintenance formed on the first end case 36 is maintained. The hole 36a is supposed to be exposed.

In addition, when both the 1st connection case cover 37c and the 2nd connection case cover 37d are a cover attached to the connection case 37, when the 1st connection case cover 37c is removed from the connection case 37, The maintenance hole 37b formed in the connection case 37 when the maintenance hole 37a formed in the connection case 37 is exposed and the second connection case cover 37d is removed from the connection case 37. This exposes.

By opening these maintenance covers 36b, 37c, and 37d, maintenance (exclusion of residual grain kernels, etc.) inside each case 36 · 37 is possible.

Moreover, about the method of attaching these maintenance covers to a case, you may be the structure which tightens the whole with a bolt, and may be fastened with a bolt in the state which made the case open and close through a shaft, and is not limited.

In the related art, the outer color of each cover 36b, 37c, 37d is the same color as the outer color of each case 36 · 37, which is a peripheral part of these covers. Specifically, each cover 36b, 37c, 37d and each case 36, 37 are formed of the same material (for example, aluminum) so that the ground color (silver white in the case of aluminum) is the same, or painted in the same color. It is supposed to be.

In this case, it is difficult to distinguish between the respective covers 36b, 37c, 37d and these peripheral parts, and at which position the respective covers 36b, 37c, 37d for maintenance are arranged in the water-based portion 80. It is difficult for the operator to grasp.

Therefore, in the combine 100, the outer surface color of each cover 36b, 37c, 37d for maintenance becomes a color different from the outer color of each case 36 * 37 which is a peripheral part of these covers. In this embodiment, each cover 36b * 37c * 37d and each case 36 * 37 are all formed from aluminum, and the color of the base itself is the same as silver white, but each cover 36b * 37c * 37d of It is supposed to paint green on the outside. And the outer color of each cover 36b * 37c * 37d and the outer color (silver white) of each case 36 * 37 are made different.

In this way, by maintaining the outer color of each cover 36b, 37c, 37d for maintenance different from the outer color of these peripheral parts (each case 36 · 37), the cover for maintenance by the operator (that is, Each cover 36b, 37c, 37d) can be easily identified. Therefore, any of the parts (covers, etc.) provided in the water-based unit 80 prior to the maintenance work of the water-based unit 80, which part is a maintenance cover (that is, each cover 36b, 37c, etc.). The operator can recognize at a glance.

Next, the operation of the maintenance system display mechanism will be described.

When the start command of the maintenance system display mechanism is input by the operation of the input device 92, the controller 90 responds to the main category corresponding to the main target maintenance part shown in FIG. 12 on the display display 91. FIG. Display the maintenance site position indication.

The operator selects a function part including a desired maintenance target part such as the threshing device 5 while looking at the maintenance part position display of large classification, and inputs the input operation to specify the selected function part. For. When a command for selecting a function portion is input by the input device 92, the controller 90 maintains a maintenance portion corresponding to the small-class maintenance target portion as shown in FIG. 13 on the display display 91. Display the position mark. Although FIG. 13 shows that the functional part is the case of the selection part 103, it is of course possible for an operator to select another functional part and to display it on the display display 91. FIG.

In addition, the operator selects a desired maintenance target site such as the water-receiving unit 80 and the like while looking at the maintenance category position display of the small classification as shown in FIG. 13, and inputs to specify the selected maintenance target site. The operation is performed on the input device 92. When a command for selecting a maintenance target site is input by the input device 92, the controller 90 displays a cover position corresponding to the maintenance target site as shown in FIG. 14 on the display display 91. Is displayed. Although FIG. 14 shows that the maintenance target site is the water-based unit 80, it is of course possible for the operator to select another maintenance target site and display it on the display display 91.

As described above, the operator displays the desired maintenance target site on the display display 91 by using the maintenance system display mechanism, and the positional information of the maintenance cover provided in the maintenance target site and Open sequence information can be obtained.

In addition, the operation of the maintenance system display mechanism is not only commanded by the operation by the input device 92. It is ordered automatically even in the case of an abnormality in which a situation requiring maintenance is urgently required.

As shown in FIG. 11, the abnormality detection sensor 93 is equipped in each maintenance target site | part. The abnormality detection sensor is, for example, a blockage detection sensor installed in a conveyor for grain grain conveyance, and outputs an abnormal signal when rice or grain grains are blocked in the conveyor and the conveyor cannot operate normally. The sensor for outputting the abnormality detection as a signal when an abnormality occurs in each device constituting the maintenance target site and emergency maintenance is not limited to the conveyor for grain grain conveyance, is an abnormality detection sensor 93. to be. The abnormality detection sensor 93 is arrange | positioned at the appropriate number in each maintenance target site | part as needed.

The maintenance system display mechanism is also provided with an alarm device 94 as a means for reporting abnormality detection by the abnormality detection sensor 93. As the configuration of the alarm device 94, an audio output may be used to alert the worker's hearing, and an alarm may be alerted to the worker by an optical signal such as lighting or blinking, such as an LED lamp, to warn the operator of the abnormality. good.

In addition, based on the abnormality detection by the abnormality detection sensor 93, the controller 90 controls the image output of the display display 91, and makes display of an abnormal state. Specifically, the main body schematic diagram shown in FIG. 12 is displayed on the display display 91, and the functional part containing the maintenance target site | part where abnormality was detected in this main body schematic diagram becomes different from other normal functional parts. . The display different from other normal functional parts means, for example, a blinking display, a display in a special color different from the display color of the functional part, a display by a special shape display, or the like.

When the display of the abnormal state is being performed, the operator merely performs a simple operation (such as one-time contact with the key) on the input device 92 without selecting and inputting a function portion or a maintenance target portion as usual. The maintenance site position display and the cover position display of the abnormal part are performed. For this reason, it can be recognized by looking at the display of the display display 91 that an abnormality such as clogging of a grain of grain has occurred at an operator or a maintenance target site, and it is possible to perform maintenance to solve this abnormality. .

Next, the display means of the maintenance site according to the second embodiment will be described.

In the display means of the maintenance site which concerns on 2nd Example, it is set as the structure provided with the order guide plate in the vicinity of the opening-closing operation member.

The opening / closing operation member and the order guide plate which concern on one Embodiment of this invention are demonstrated.

As a conventional problem, the order of removing the inside of the threshing apparatus 5, removing or removing the mantle, or performing maintenance or the like (for example, a procedure in which the feed chain 6 is opened) is It is described and explained only in the handling instructions. For example, even if the description plate (order guide plate) was attached to the body, it could not be known unless the order was read in detail. Therefore, when the worker who performs the maintenance or the like is an unfamiliar person such as a new farmer, when opening each part of the combine (for example, the feed chain 6). It was inconvenient that it took time by trial and error because it was difficult to know the order. In addition, there were not many people whom we did not know unless we called person of store.

This embodiment is a structure which opens and closes an opening / closing operation member in each of the inspection part located on one outer side of a work part, and the cover which covers the inspection part, and makes it possible to open | release, WHEREIN: The said opening / closing operation member itself is different from other members. In addition, the number or symbol which shows a release procedure is attached to the said opening operation member itself, or its vicinity.

That is, only the part which needs to open operation is colored so that a different color and a different color may be colored, and it is comprised so that the opening and closing operation member which needs to contact minimum minimum may be colored. By coloring in the most necessary places, it eliminates the opportunity to contact unnecessary points, and eliminates unnecessary disassembly and inadvertent accidents.

In addition, the "opening / closing operation member" as used here means an operation member, such as opening / closing a cover, releasing a lock, releasing a tension, or releasing a fixing.

Here, the opening / closing operation member (lock handle 149, open handle 159, etc.) is configured to color or attach a figure indicating a release order, an arrow indicating a release direction, or the like (see FIGS. 16 to 18). ). In the case where the space is not present or narrow, the coloring is simply printed on the opening / closing operation member (the net stopper 87 or the handle 88) without directly printing the number or the like. By attaching or drawing the order guide plate 98 on which the printed document is printed, directly to each member of the body, the operator knows the operation method or order (see FIG. 19).

Next, the opening and closing operation member will be described.

As shown in FIG. 16, the combine 200 is covered by the handling chamber cover 147 so that the upper and upper side surfaces (upper left surface) of the threshing apparatus 5 can be opened and closed. The lock handle 148 and the open handle 149 which are opening / closing operation members are provided on the side surface of the handling chamber cover 147 to protrude laterally. The handles of the lock handle 148 and the open handle 149 of the handling chamber cover 147 are colored different from the color of other parts (covers) and the like, and the arrows indicating the opening and closing directions and the operation sequence numbers are printed. It is.

The outer side of the drive unit of the threshing apparatus 5 and the sorting unit 103 is covered by the threshing side cover 145 so as to be openable or detachable, and the outer side of the drive unit of the discharge straw processing unit 104 is the cutter side cover 146. It is covered so that opening and shutting is possible or is removable. A handle portion 160 · 160 is provided at the upper and lower centers of the threshing side cover 145 to hold the cover at appropriate intervals. The cover is disposed at the center of the upper and lower sides of the upper side of the cutter side cover 146. A handle portion 161 is provided for holding it off. The said handle part 160 * 160 * 161 is also an opening / closing operation member. The handle portions 160, 160, and 161 are colored in different colors from those in other portions, and the sequence numbers are printed. Each number or printing guide plate (or printing portion of the order number) is colored in the same color as the handle (for example, blue in this order).

In order to check the threshing apparatus 5 and the like, first of all, the cutting arrangement arranged on the steering wheel 13 is arranged in the side column 15 of the height adjustment switch “lower” side or the driving unit 10. With the height adjustment lever on the lower side, the mowing device 3 is placed in the lowest state, the side divider (not shown) is rotated to the working position, and the engine is stopped.

And it removes in order number. That is, the threshing side cover 145 (number "1") which is a cover of the base side of the threshing apparatus 5 shown in FIG. 16, and the cutter side cover which is the cover of the base side of the discharge | emission straw processing part 104 ( 146) (the number "2" is printed) is removed. The threshing side cover 145 and the cutter side cover 146 may be integrally formed. Then, the lock handle 148 (number 3 is printed) that is arranged on the surface of the handling chamber cover 147 is pushed up to release the lock, and the lock handle 148 is attached to the side of the lock handle 148. The handling chamber cover 147 is pushed upward with the open handle 149 (printing number "4").

In addition, the opening / closing operation member and the order guide plate concerning the opening order of the feed chain 6 (opening order of the threshing part) are all colored in the same color (blue in this embodiment).

As mentioned above, the threshing side cover 145, the cutter side cover 146, and the handling chamber cover 147 are opened or removed, respectively, so that the inside of the gas side can be seen.

As shown in FIG. 17, in the exposed gas side surface, the feed chain 6 arrange | positions the driven sprocket 97 * 97 in the front part and the rear part of the chain stand 95, and tensions the lower part of the intermediate part from all. The drive sprocket 52 is arrange | positioned below the tension roller 96 in the state which arrange | positioned the roller 96 and set the chain stand 95 as a set. The tension roller 96 is connected to the tension lock lever 85 via a spring 106. Moreover, the frame lock lever 86 is arrange | positioned at the rear chain stand 95b arrange | positioned at the rear part of the chain stand 95, The rear chain stand (frame) is rotated on a frame (gas frame) by rotating the said frame lock lever 86. 95b) can be fixed.

The tension lock lever 85 and the frame lock lever 86 are colored in a different color (blue in this embodiment) from the other parts, and the numbers of the open order (open order of the threshing part) are printed or attached. .

Thus, the tension lock lever 85 (number "5") connected with the tension roller 96 arranged in the chain stand 95a in the state which opened each said cover 145 * 146 * 147 as mentioned above in this way. As shown in Fig. 17, the lens is rotated downward in a clockwise direction, the tension by the tension roller 96 is released to remove the feed chain 6 from the drive sprocket 52, and then the frame lock. The lever 86 (printing the number &quot; 6 &quot;) is also rotated clockwise to push it straight forward to unlock the rear chain rest 95b from the base. From there, the chain chain 95 (printing number "7") suspended from the feed chain 6 is rotated laterally around the rear chain stage 95b and pulled straight forward to open the feed chain 6 (See FIG. 18).

When closing the feed chain 6, the feed chain 6 can be closed by performing in a reverse order to the above.

By configuring as described above, since the opening order of the feed chain 6 and the removal order of the handling network 79 can be immediately recognized and operated, the handling time is small. Moreover, by using a number, an arrow, etc. for the guide of the said procedure, the agricultural work machine to which this invention is applied can also be used by foreigners other than Japanese, and can respond also to the globalization currently used abroad. That is, even if it is impossible to use literacy, it can be used.

Next, the removal procedure of a handling network is demonstrated.

Desorption of the handling network 79 mainly causes clogging, abrasion, damage, or deformation of the handling network 79, and causes debris to fall off, causing not only poor sorting but also failure. In such a case, it needs to be replaced and then removed.

As shown in Fig. 19, at one side (left) end of the handling network 79, a locking portion 89 and a handle 88 are provided, and the locking portion 89 is a network stopper provided at the base (gas frame) side. (87) is fixed. The mesh stopper 87 has a hook-like tip, and a force is applied to the locking side by a biasing member such as a spring, and the locking portion 89 is pushed by pushing the handling net 79 in the set position. It is set as the structure which hangs on the net stopper 87, and is fixed. The net stopper 87 is colored in a different color from the other part (for example, yellow), and is attached to the vicinity of the net stopper 87 with an arrow indicating the release direction and a sequence guide plate for printing the sequence number. . In addition, the handle 88 is also colored in a different color from other parts (for example, yellow), and is attached with a sequence guide plate 98 in which the arrow indicating the sequence number and the release direction is printed in the vicinity thereof. The order guide plate 98 may be a name plate. However, the opening / closing operation member and the order guide plate 98 concerning the removal of the handling network 79 are set to a spot color (for example, yellow color) from the color of the opening sequence of the feed chain 6 up to that time. However, the number is set consecutively from the opening order of the feed chain 6. Moreover, it is also possible to set it as the structure which is not made into a sequence.

In such a configuration, when removing the handling network 79, the feed chain 6 is left open in the above-described order. And the handle 88 (numbered) protruding the handling network 79 in the direction of the arrow in the direction of the arrow while pushing down the network stopper 87 (corresponding to the number "8") of the handling network 79 (number To (9)).

The handling network 79 can be removed in the above procedure.

When detaching or attaching a new handling network 79, it can attach by performing a reverse order.

In addition, although the opening / closing operation member and the order guide plate are colored blue for the thing related to the opening order of the said feed chain 6, and yellow for the removal order of the handling network 79, the color of the opening / closing operation member and the order guide plate is The color is not limited as long as it can be identified by an operator without following the embodiment.

By coloring as mentioned above, even if the pattern of various orders is intertwined, it becomes possible to identify. For example, opening / closing operation members, such as an operation lever with a plurality of processes of the opening sequence of the feed chain 6, and order guide plate are made into the same color. Colors are sorted in a different color from the opening / closing operation member and the order guide plate for opening the discharge straw cutter 35. In addition, the opening of the grain grain tank 7, the opening of the engine room, the opening of the harvesting section, and the like are also separately color-coded, such as a lock lever, a fixing screw, a name plate indicating the sequence, and also printing the sequence number separately.

By such a configuration, it is possible to easily distinguish the difference of the order patterns by color vision, and also to make it possible to judge the operation system by color, and to prevent the misoperation of various orders.

Next, the display means of the maintenance site according to the third embodiment will be described.

In the display means of the maintenance site according to the third embodiment, the color of the opening / closing operation member is set to the color of the main body and the peripheral device.

As shown in FIG. 20, the left side cover 180 is covered by the outer side of the combine 300, and is removed at the time of inspection and cleaning of the feed chain 6 and the discharge | drinking straw cutter 35. As shown in FIG. Usually, the left side cover 180 is coated with an exterior, and in this embodiment, it is assumed that it is painted in red.

A recess 182 is provided on the outer side of the left side cover 180, and a handle 181 is provided in the recess 182 to hold the left side cover 180 in an attached state. In addition, although the recessed part 182 and the handle part 181 are respectively provided in the upper and lower centers of the front part and the rear part of the left side cover 180 in this embodiment, the left side cover 180 is easily removed and it is easy to remove it. It is good if it is a site | part which can be caught, and it is not limited to the arrangement | positioning shown in a present Example.

Here, the handle part 181 is colored yellow, and it is outstanding from the outside of the red left side cover 180 seen from the outside at the same time. That is, the operator can recognize the position of the handle portion 181 in a moment by the contrast of the color of the red of the left side cover 180 and the yellow of the handle portion 181.

In this way, for example, when checking and cleaning the feed chain 6 or the discharge straw cutter 35, the operator can recognize the position of the handle portion 181 in an instant, and unlock the handle portion 181. And the left side cover 180 can be removed. In addition, the operator may check the position of the recess 182 by checking the position of the handle 181 by fumbling by hand during the night work, for example. The recess 182 may be the same color as the left cover 180 or may be the handle 181.

That is, the operation efficiency at the time of cover attachment and detachment is improved by distinguishing the handle part 181 from the circumference by the contrast of a color and a concave shape.

In addition, although the left side cover 180 was introduce | transduced in this embodiment, if this cover is peeled off at the time of maintenance of the combine 300 (for example, the right side cover which is not shown in figure), this embodiment can be applied. .

Combine 300 is generally a place where it is easy to be clogged during bad work (feed chain 6, threshing device 5, discharge straw cutter 35), a place where sufficient cleaning is required at the end of work (threshing device 5) , The grain grain (7), the inside (grain grain tank (7), the discharge straw cutter (35)) which are hard to check, etc. are made into a structure which can be opened or detached, and by operation of the open lever which is a handle member as a structural fastener, As a means of movement, the structure which can open a work part can make maintenance easy.

As shown in FIG. 21, the operator can confirm the drive part of the feed chain 6 and the rocking | fluctuation sorting board 27 by removing the said left side cover 180. As shown in FIG. By operating the feed chain open lever 191, the feed chain 6 releases the tension of the tension spring 195 and at the same time releases the lock. That is, when the feed chain open lever 191 is rotated downward, the lock between the feed chain frame and the gas frame is released, and at the same time, the tension spring 195 biasing the tension roller 196 is relaxed, so that the feed chain 6 It can remove from the drive sprocket 197 which protruded from the side. The feed chain has a configuration in which the front side rotates, i.e., opens outward, with the rear portion (left rear portion) as a point. In this way, the worker can easily inspect and clean the feed chain and detach the receiving network of the threshing apparatus 5.

As shown in FIG. 22, the said grain grain tank 7 removes a drive belt, pulls out a fixing pin, and rotates, ie, opens outward to the rear part of a body by operating the grain grain tank open lever 101. As shown in FIG. I am made to become the composition. By operation of the grain kernel open lever 101, the grain kernel open lever lever 101a is pulled forward, and the grain kernel 7 is pulled forward to open. In this way, the operator can easily check and clean the belt, the grain-grain conveyor 33, the release port of the reduction conveyor 105, the hydraulic tank, etc. inside the grain grain tank 7.

As shown in Figs. 21 and 23, for the discharge straw cutter 35, the operator first removes the left side cover 180 described above, and operates the cutter tension lever 192 to operate the cutter drive belt 201. From the cutter pulley 202. Next, the discharge straw cutter 35 is opened while pushing the cutter lock lever 193. In this way, an operator can easily check and clean the threshing apparatus 5 rear part and the discharge | drinking straw cutter 35. FIG.

Here, the feed chain open lever 191, the cutter tension lever 192, and the cutter lock lever 193 are colored in light blue, and by opening the left side cover 180, eyes from among the internal devices on the left side are held in unison. It is intended to stand out.

In addition, the grain grain tank open lever 194 is similarly colored in light blue, and is made to stand out in the internal apparatus of the right side at the same time by opening the right side cover which is not shown in figure.

In other words, the operator normally adjusts the position of each of the open levers 191, 192, 193, 194 by contrasting the color of the index internal device close to black with the light blue of each of the open levers 191, 192, 193, and 194. It can be recognized in an instant.

In this way, for example, when checking and cleaning the feed chain 6 and the discharge straw cutter 35, the open lever which the operator should operate can be recognized immediately. In addition, it is possible to prevent an operator from inadvertently operating a lever other than the open lever at the time of maintenance, thereby ensuring safety at the time of maintenance.

That is, the work efficiency at the time of maintenance is improved by distinguishing each open lever 191, 192, 193, 194 from the circumference by the contrast of color.

In another embodiment, the handle portions 211, 212, 102a, 101a of the feed chain open lever 191, the cutter tension lever 192, the cutter lock lever 193, and the grain grain tank open lever 194. It is assumed that only color is light blue.

Even if it does in this way, it has the same effect as the above-mentioned embodiment, and it can easily recognize which part should be operated when operating an open lever. For example, if the open lever handle part of the combine before application of this embodiment is made of resin or rubber and can be removed, the present embodiment can be simply applied by replacing only the handle part colored in light blue.

At the end of the maintenance work, the opened devices are stored in their normal positions, and then the respective opening levers 191, 192, 193, 194 are returned to their original positions, the apparatus is fixed in the normal state, and the left side cover ( 180). Here, the open levers 191, 192, and 193 have a structure in which the left side cover 180 is not attached unless they return to their original positions. That is, when the open levers 191, 192, 193 do not return to their original positions, a part of the open levers 191, 192, 193 touches the protrusions provided on the inner surface or the inner surface of the left side cover 180, and the left side. It is a structure which cannot engage with the to-be-engaged part provided in the handle part 181 of the cover 180 to the caught part provided in the gas side, cannot be attached to this main body side, and falls out.

In this way, even if the operator forgets to fix the device opened by the open levers 191, 192, 193 to the normal position at the end of the maintenance work, the device is fixed by not attaching the left side cover 180. It can be recognized that it is not.

In other words, since the cover cannot be mounted in a situation where the maintained equipment is not fixed to the normal position, mistakes in maintenance work are prevented and work safety is improved.

This embodiment is intended to be a device that is easy for everyone to use. In the maintenance work which improvement was desired conventionally, the open lever by color is identified so that a woman, an elderly person, a new farmer, that is, anyone can easily work, and work efficiency at the time of maintenance work Improved.

In this embodiment, the open levers 191, 192, 193, and 194 are colored in light blue. However, the colors may be different from those of the internal device, and the present invention is not limited to the color scheme of the present embodiment. In addition, in this embodiment, although the feed chain open lever 191, the cutter tension lever 192, the cutter lock lever 193, and the grain grain tank open lever 194 are mentioned as an open lever as an example, it is not an operation lever but a main tea. It is preferable to apply this embodiment as long as it is an open lever used at the time of nonce.

The present invention can be applied not only to combines, but also to industrial farms having an overall agricultural work vehicle or a maintenance unit for opening and closing.
