  However, in the general-purpose combine disclosed in Patent Document 1, when the relative height of the reel with respect to the traveling machine body is equal to or higher than the predetermined height, the automatic storage control of the auger is prohibited regardless of the auger rest switching position. The automatic storage control to the second storage position where there is no risk of this is also prohibited, and the workability may be reduced.

  Further, in the general-purpose combine of Patent Document 1, when the reel is raised to a predetermined height or more during automatic storage control, the automatic storage control of the auger is stopped, so that the operator does not recognize that the auger is not stored. There was a risk of running the aircraft.

The present invention has been created in order to solve these problems in view of the above circumstances, and the invention of claim 1 is configured such that a cutting portion is connected to a front of a traveling machine body so as to be movable up and down, The mowing unit supports the reel so that it can be moved up and down, and the traveling machine body supports the auger so that it can turn left and right and can swing up and down. A control unit that executes automatic storage control for storing in a storage position that is lowered to a position that wraps on a reel that is positioned at a predetermined height or higher is provided, and automatic storage control is performed by detecting execution operation of automatic storage control by the execution operation means. The control unit is configured to be executed, and a first storage position where the auger wraps with the reel in plan view and a first storage position positioned on the left and right outside of the first storage position so as not to wrap the auger with the reel in plan view At least two storage positions of the storage position is set to the control unit, the receiving position of Ogaresuto which supports receiving the auger, and a first receiving position receiving the housing has been auger in the first storage position, switchably configured to at least two locations between the second receiving position receiving the auger housed in the second storage position, or receiving position of Ogaresuto is a state of being switched to the first receiving position, Switching state detecting means for detecting at least two states of whether the state is switched to the second receiving position is provided, and the control unit detects the switching of the augerest to the first receiving position by the switching state detecting means. If the automatic storage control is executed so that the auger is stored in the first storage position, the switching state detecting means detects the switching of the auger rest to the second receiving position. The automatic storage control is executed so that the auger is stored in the second storage position, and the control unit switches the auger rest to the first receiving position. When the detection means detects and the relative height of the reel with respect to the traveling machine body is equal to or higher than a predetermined height, execution of automatic storage control is prohibited even if an automatic storage control execution operation by the execution operation means is detected. When the switching of the augerest to the first receiving position is detected by the switching state detecting means and the relative height of the reel with respect to the traveling machine body is less than a predetermined height, the reel is not allowed to rise. The automatic storage control is executed, the switching of the augerest to the second receiving position is detected by the switching state detecting means, and the relative height of the reel with respect to the traveling machine body is equal to or higher than a predetermined height. The general-purpose combine is characterized in that automatic storage control is executed based on detection of an execution operation of automatic storage control by the execution operation means.
The invention of claim 2, wherein the control unit also detects the execution operation of the automated storage control by executing operation means, when not performing automatic storage control, to claim 1, characterized in that outputs a warning It is the general purpose combine described.

According to the invention of claim 1, when the relative height of the reel with respect to the traveling machine body is equal to or higher than the predetermined height, the auger does not possibly collide with the reel while prohibiting the automatic storage control of the auger. Since automatic storage control to the second storage position is allowed, it is possible to avoid a decrease in workability. In addition, when the automatic storage control is executed so that the auger is stored in the first storage position, the lifting operation of the reel during the automatic storage control is prohibited. Therefore, the automatic operation of the auger is performed based on the lifting of the reel during the automatic storage control. It is possible to avoid stopping the storage control, and as a result, it is possible to prevent the inconvenience of causing the aircraft to travel without the auger being stored.
Further, according to the invention of claim 2 , even if the execution operation of the automatic storage control by the execution operation means is detected, if the automatic storage control is not executed, an alarm is output. It is possible to prompt the user to re-operate the automatic storage control.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 and 2 are a right side view and an overall plan view of a general-purpose combine to which the present invention is applied. This general-purpose combiner is coupled to a traveling machine body 2 supported by a pair of left and right crawler type traveling devices 1 and 1 which are traveling parts, and is connected to the front of the traveling machine body 2 so as to be able to be raised and lowered, thereby performing harvesting work of cereal grains in a field. The cutting part 3 is provided.

  The traveling machine body 2 is provided with a control unit 4 on which an operator enters and performs a steering operation at a right side position in the vicinity of the rear side of the cutting unit 3, and is cut by the cutting unit 3 on the diagonally left rear side of the control unit 4. A threshing unit 6 for performing threshing work of cereals and the like is installed, and a grain tank 7 for storing a grain which is a processed product threshed by the threshing unit 6 is arranged behind the control unit 4 and on the right side of the threshing unit 6. It is comprised by providing the discharge part 8 which discharges the sawdust etc. after threshing behind the threshing part 6.

  In addition, an auger 9 that discharges grains stored in the Glen tank 7 to the outside of the machine is supported by the traveling machine body 2 so as to be turnable in the left-right direction and swingable up and down. Incidentally, the auger 9 is stored in the predetermined storage positions A and B in a state where the grain is swung down to the lowest position so as to fall down when the grain is not discharged from the grain tank 7 when not in use. .

  The threshing portion 6 is formed with a handling chamber (not shown) whose upper and outer sides are covered with a cylinder cover 11 so as to be freely opened and closed. The handling chamber has a cylindrical handling cylinder (not shown) extending in the front-rear direction. ) Is supported so as to be rotatable about its axis. The threshing process of the cereal is performed by introducing the cereal from the cutting unit 3 into the handling chamber in a state where the handling cylinder is being rotationally driven. Incidentally, the cylinder cover 11 is mounted and supported on the traveling machine body 2 side so as to rotate up and down with the left and right inner ends as fulcrums.

  The mowing unit 3 includes a feeder 12 disposed in the rear half and a mowing frame 13 disposed in the front half, and a divider 14 that is a front-rear direction weed body protruding forward is disposed on the mowing frame. 13 are provided integrally on the left and right side walls, respectively, and a narrow guide 16 that is a weeding body projecting outward is provided on the outer side wall of the cutting frame 13 on the uncut (specifically, left) side wall. A cylindrical frame-shaped take-up reel (reel) 17 extending in the direction is arranged so as to be positioned between the left and right dividers 14 in a plan view, and between the left and right cutting frames 13 below and behind the take-up reel 17. The reciprocating cutting blade 18 in the left-right direction is erected so as to be positioned, and the columnar scratching body 19 extending in the left-right direction is positioned obliquely above and behind the cutting blade 18 so that the cutting frame 13 Left and right side walls , The rotating drivable supported by the shaft about its own.

  Incidentally, the narrow guide 16 is supported so that the posture can be switched between a storage posture accommodated along the outer wall surface of the cutting frame 13 and a deployed posture deployed from the cutting frame 13 to the uncut side. The narrow guide 16 in this unfolded posture extends such that the front portion and the middle portion are inclined leftward and rightward outward from the front end side of the cutting frame 13, and the rear portion extends right behind.

  And the cutting part 3 attaches and supports the rear end part of the main body to the traveling machine body 2 side so that the whole swings up and down. In addition to this, a lift cylinder 21 is provided between the lower surface side of the feeder 12 and the front lower end side of the traveling machine body 2. It is driven up and down.

  The take-up reel 17 is an electric cylinder and is arranged around its own axis between a pair of left and right support arms 23 supported by the feeder 12 via a support member 22 that moves the take-up reel 17 back and forth. It is supported so that it can rotate freely. Between the support arm 23 and the cutting frame 13, reel cylinders 24 for moving the scraping reel 17 up and down with respect to the main body of the cutting unit 3 by extension and contraction are installed on the left and right, respectively, and the support arm 23 on the other side is installed. Is constituted by a transmission case 20 that transmits power to the take-up reel 17 side. That is, the take-up reel 17 is moved up and down with respect to the main body of the cutting unit 3 and is rotated about its own axis by the power from the transmission case 20.

  According to the cutting unit 3 having such a configuration, the main body of the cutting unit 3 and the scraping reel 17 are lowered, the scraping reel 17 is driven to rotate, and the cutting blade 18 is driven to cut (specifically, left and right reciprocating driving). When the traveling machine body 2 travels forward in this state, the left and right dividers 14 guide the rice straw in the field located in front of the cutting unit 3 between the left and right side walls of the cutting frame 13.

  In this manner, the cereals guided between the left and right side walls of the cutting frame 13 by the left and right dividers 14 are cut forward by the take-up reel 17 and the cutting blade 18, while the whole is moved forward. It is scraped and introduced into the feeder 12 by the rear scraper 19. The cereal grains introduced into the feeder 12 are conveyed rearward by a conveying device (not shown) such as a conveyor installed in the feeder 12 and passed to the threshing unit 6 described above.

  In addition, the narrow guide 16 located in the outermost end side of the cutting part 3 (specifically, the leftmost end side of the cutting part 3) is a side that keeps the uncut-side grain straw away from the traveling machine body 2 and the cutting part 3. It is configured to guide to the (right and left outer sides), and prevents the uncut side cereal from falling down or being cut unintentionally.

  FIG. 3 is an overall left side view of the general-purpose combiner showing a state where the main body of the cutting unit and the take-up reel are lowered to the lowest position, and FIG. FIG. 5 is an overall left side view of the general-purpose combine that shows a state in which the take-up reel is raised to the highest position. FIG. 5 shows that the main body of the cutting unit is raised to the highest rise position and the take-up reel is lowered to the lowest drop position. FIG. 6 is an overall left side view of the general combine showing the state, and FIG. 6 is an overall left side view of the general combine showing the state in which the main body of the cutting unit and the take-up reel are raised to the highest position.

  As shown in FIG. 3, when the main body of the cutting unit 3 and the take-up reel 17 are both lowered to the lowest position with respect to the traveling machine body 2, the main body of the cutting unit 3 is brought into a state close to the field scene. At the same time, the take-up reel 17 comes close to the main body side.

  Also, as shown in FIGS. 4 and 5, when either one of the main body of the reaping part 3 or the scraping reel 17 is raised to the highest position and the other is lowered to the lowest position, the storage is performed. With respect to the auger 9 stored in the positions A and B, the scraping reel 17 is on the upper side to a height that is not wrapped in a side view (up to a height that does not reach the auger stored in the storage positions A and B). Displace.

  Furthermore, when both the main body of the cutting unit 3 and the take-up reel 17 are raised to the highest position, the take-up reel 17 is moved to a height at which the take-up reel 17 wraps in a side view with respect to the auger 9 stored in the storage position (storage). To a height that reaches the auger 9 housed in the position). Incidentally, members other than the take-up reel 17 of the cutting unit 3 are arranged and configured so as not to wrap in a side view when the main body and the auger 9 are moved up and down.

Next, the auger will be described with reference to FIGS. 1 and 3 to 13.
The auger 9 includes a vertical cylinder 26 in the vertical direction disposed at a position to the right of the rear end of the traveling machine body 2, and a linear discharge cylinder 27 having a base end supported by the upper end of the vertical cylinder 26. Yes. The vertical cylinder 26 is rotationally driven around its own axis by a hydraulically operated auger motor 28, and the discharge cylinder 27 as a whole swings up and down by the expansion and contraction of the auger cylinder 29 installed between the discharge cylinder 27 and the vertical cylinder 26. Moved.

  That is, the auger 9 is swung left and right by the auger motor 28, and the auger 9 is vertically swung by the expansion and contraction of the auger cylinder 29. And the front-end | tip part (front-end | tip part of the auger 9) of the discharge cylinder 27 is located right above a grain supply position, and the auger spiral (not shown) installed in the vertical cylinder 26 and the discharge cylinder 27 is rotationally driven. By doing so, the grain in the Glen tank 7 is discharged out of the machine from the discharge port 31 at the tip of the auger 9.

  FIG. 7 is a plan view showing the left-right turning range of the auger, and FIG. 8 is a side view of the general-purpose combine in a state where the auger is swung upward to the highest position. The auger 9 is stowed by the storage positions A and B where the discharge cylinder 27 extends from the base end to the front end in the diagonally left direction in the plan view, and the discharge cylinder 27 extends from the base end to the front end in the right direction in the plan view. Steering side position C passing right above the portion 4, a right position D in which the discharge cylinder 27 extends rightward in a plan view from the base end toward the front end, and a plan view in which the discharge cylinder 27 extends from the base end toward the front end. As a turning position, there is a right rear position E extending right behind and a right left position F in which the discharge cylinder 27 extends rightward in plan view from the base end toward the tip end.

  Furthermore, there are two types of storage positions A and B: a travel storage position (first storage position) B and a work storage position (second storage position) A. The work storage position A is the travel storage position B. On the other hand, the auger 9 is disposed at a position slightly turned left.

  That is, the position where the auger 9 is turned to the maximum counterclockwise is the work storage position A. When the auger 9 is turned clockwise from the work storage position A, the travel storage position B → the control unit. It is displaced from the side position C → the right position D → the rear position E, and finally, it is displaced to the right position F, which is the position of maximum rotation clockwise. Here, between the right position D and the right position F is a discharge position for discharging the grain in the grain tank from the auger.

On the other hand, when the auger 9 is swung upward to the uppermost position, the discharge tube 27 is inclined upward by about 45 degrees from the base end toward the tip, and the auger 9 is swung downward to the lowermost position. In this case, the discharge tube 27 is close to 0 degrees from the proximal end toward the distal end (see FIGS. 3 to 6).

  When the auger 9 turned to one of the two storage positions A and B is swung downward to the lowest position so as to fall down along the upper surface side of the traveling machine body 2, the middle part of the discharge cylinder 27 Is received by the auger rest (auger receiving) 32 installed in the traveling machine body 2, and the auger 9 is housed in a state of being stably supported.

  For this reason, the auger rest 32 has a travel receiving position for receiving the midway part of the auger 9 stored in the travel storage position B and a work receiving position for receiving the midway part of the auger stored in the work storage position A. It is supported on the traveling machine body 2 side so as to be switchable to two places.

  The auger 9 stored in the travel storage position B wraps around the take-up reel 17 and is stored in the machine width of the travel machine body 2 and the cutting unit 3 while being stored in the work storage position A in plan view. In plan view, the auger 9 thus formed is in a non-wrapped state with the take-up reel 17 and protrudes outward from the vehicle body width of the traveling machine body 2 and the cutting unit 3 (see FIG. 1).

  In addition to this, the distal end portion of the auger 9 that protrudes to the left from the traveling machine body 2 by being stored in the work storage position A is located behind the front end of the narrow guide 16 in the unfolded position described above in plan view. In the plan view, the narrow guide 16 is positioned closer to the take-up reel 17 (on the left and right sides) than the outermost end of the narrow guide 16 in the deployed posture. The narrow guide 16 in this unfolded posture is disposed at a position where it can be seen by an operator in the control unit 4. For this reason, the situation where the tip of the auger 9 stored in the work storage position A collides with the obstacle is efficient if the field is run while visually checking so that the obstacle does not collide with the narrow guide 16. Can be prevented.

  9 and 10 are a left front perspective view and a right rear perspective view showing the auger rest switched to the travel receiving position, and FIGS. 11 and 12 are a left front perspective view showing the auger rest switched to the work receiving position. FIG. 13 is an exploded perspective view showing an augerest mounting structure. The augerrest 32 is formed in a wedge shape with the upper side in the front view open so that the peripheral surface of the discharge cylinder 27 of the auger 9 descending can be smoothly received. By 33, it is supported by the location near the control part 4 in the boundary part of the threshing part 6 and the Glen tank 7. FIG.

  More specifically, the augerest 32 having a V-shape when viewed from the front protrudes in a bifurcated manner to the left and right, and of these left and right protruding portions, the protruding portion near the threshing portion 6 Compared with the projecting portion near the tank 7, the hook portion 36 that protrudes further upward is attached to the back side of the auger rest 32 by welding or the like so that the lower portion in the side view is opened. Is formed.

  The support device 33 connects a vertical support column 37, a left and right support stay 38 projecting from the upper end of the support column 37 toward the threshing portion in plan view, and a midway portion of the support column 37 and a midway portion of the support stay 38. Thus, a reinforcing plate 39 to be reinforced and a support member 41 provided integrally on the lower end side of the support column 37 are provided. The support member 41 is the threshing frame 42 side that constitutes the frame of the threshing unit 6 (specifically, the lock member 60 side that is welded to the threshing frame 42 and releasably locks the grain tank 7 to the traveling machine body 2 side). In addition to being bolted to the support member 41, the support member 41 includes a rod-shaped threshing-side connecting frame 43 bent toward the threshing frame 42 and a rod-shaped bent toward the control frame 44 constituting the frame of the control unit 4. The steering side connection frame 46 is fixedly attached by welding or the like. The threshing side connection frame 43 is bolted to the threshing frame 42 side via a mounting bracket 47 provided integrally with the threshing frame 42 side end portion, and the control side connection frame 46 is connected to the control frame 44 side end. The mounting bracket 48 provided integrally with the control unit is bolted to the control frame 44, and the mounting bracket 48 of the control side connection frame 46 is welded and fixed to the middle part of the threshing side connection frame 43. As described above, the support device 33 is firmly fixed to the threshing unit 6, the Glen tank 7, and the control unit 4.

  The augerest 32 and the reinforcing plate 39 of the support device 33 are connected by a connecting arm 51. The upper and lower ends of the connecting arm 51 are attached and supported by the support device 33 and the auger rest 32 so as to be rotatable left and right.

  Then, the augerest 32 is lifted and moved to the Glen tank 7 side (right side) while maintaining the V-shaped posture when viewed from the front, so that the connecting arm 51 is moved toward the Glen tank 7 side with respect to the support device 33. As a result, the Glen tank 7 side half of the support stay 38 is fitted into the hook portion 36 of the augerrest 32 from below and engaged, and the augerrest 32 is in the travel receiving position described above. The positioning is fixed.

  On the other hand, by holding the augerest 32 and moving it to the threshing unit 6 side (left side) while maintaining the posture in a V shape when viewed from the front, the connecting arm 51 is moved to the threshing unit 6 side with respect to the support device 33. Thus, the half of the threshing portion 6 side of the support stay 38 is fitted into the hook portion 36 of the augerrest 32 from below, and both are engaged, and the augerest 32 is in the above-described work receiving position. Then, the positioning is fixed.

  Further, at each receiving position, the lock pin 52 in the front-rear direction is removably inserted into the locking plate 34 of the auger rest 32 and the support stay 38 of the support device 33, and the snap pin 53 removes the lock pin 52 from both members. The augerest 32 is locked to the support device 33 by preventing the removal. By the way, by removing the snap pin 53 and removing the lock pin 52 from the support device 33 and the auger rest 32, the fixation (lock) of the auger rest 32 to the support device 33 is released. Incidentally, a lock hole 54 through which the lock pin 52 is inserted is formed at a position opposite to the locking plate 34 and the support stay 38.

  Further, an augerest switch 56 (switching state detecting means) whose working surface faces the threshing portion side is provided at the threshing portion 6 side edge of the lower end portion of the augerest 32, while the threshing portion 6 side end portion of the support stay 38. The operating plate 57 projecting forward so as to face the working surface of the auger rest switch 56 is integrally attached and fixed.

For this reason, when the augerest 32 is switched to the work receiving position, the augerest switch 56 comes into contact with the operation plate 57 and the augerest switch 56 is turned on, while the augerrest 32 is switched to the travel receiving position. In such a case, the contact between the operating plate 57 and the auger rest switch 56 is released, and the auger rest switch 56 is turned off. That is, by detecting ON / OFF of the augerrest switch 56, it is possible to detect whether the augerest 32 is switched to the work receiving position or the travel receiving position .

  According to the auger rest 32 and the support device 33 configured as described above, by fixing the auger rest 32 to the travel receiving position, the auger that has been turned left and right at the travel storage position can be placed and stored. By fixing to the work receiving position, the auger that has been turned to the work storage position can be placed and stored.

  Even when the lock pin 52 is removed when the auger rest 32 is switched from the travel receiving position to the work receiving position or from the work receiving position to the travel receiving position, the auger rest 32 is connected to the connecting arm. Since it is always connected to the support device 33 side by 51, when the receiving position of the augerest 32 is switched, the hook part 36 of the augerest 32 can be prevented from unexpectedly coming off from the support stay 38.

  Further, the augerest 32 is configured to be able to swing left and right in an arc shape with the support device 33 side of the connecting arm 51 as a fulcrum and can be fixed by a lock pin 54 at a predetermined storage position, so that a predetermined traveling storage posture is ensured. Alternatively, it can be switched to the work storage posture. Furthermore, since the attitude of the O-rest 32 is switched by a simple link mechanism, it can be configured at low cost.

  Further, since the augerest 32 is attached to the left side of the rear end of the control unit 4 and the right side of the front end of the threshing unit 6, the augerest 32 is configured to support the base end side from the middle part of the discharge tube 27. When switching 32 to the work receiving position and the traveling receiving position, there is no need to increase the left-right slide width. Further, since the auger 9 at each storage position is stored by switching the receiving position of the single auger rest 32, the auger 9 operated at each storage position can be reliably placed and stored at a predetermined position.

  In addition, the augerest 32 is supported by the support device 33 at a position near the control unit 4 between the boundary portion between the threshing unit 6 and the Glen tank 7, and the support device 33 is inverted by the support 37 and the support stay 38. Since it is formed in a letter shape, it is arranged so that the lower side of the work receiving position of the support stay 38 (the lower left side of the support stay), that is, the upper surface side of the right end of the threshing part is opened. 32 and the support device 33 do not hinder the opening / closing operation of the cylinder cover 11 that can be opened and closed on the upper surface side of the threshing unit 6.

Next, based on FIGS. 14 to 17, the configuration of the control unit that controls the raising and lowering of the main body of the cutting unit and the take-up reel, the up-and-down swinging and the left-right turning of the auger rest will be described.
14 is a plan view of the control unit, FIG. 15 is a rear view of the multi-steering lever, FIG. 16 is a front view of the remote control, and FIG. 17 is a block diagram of the control unit.

  14, the control unit 4 includes a seat 58 on which an operator is seated, a multi-steering lever 59 disposed in front of the seat 58, and a main body disposed on the side of the seat 58 (on the left side in the illustrated example). A main transmission lever 61 which is a transmission operation tool, a sub transmission lever 62 provided on the left and right outer sides of the main transmission lever 61 (on the left side in the illustrated example), and a cutting unit 3 disposed behind the main transmission lever 61. And an auger remote control 64 installed on the rear side of the left and right sides (right side in the illustrated example) of the seat 58, and between the multi-steering lever 59 and the seat 58. A floor step 66 is formed on the floor.

  The adjustment panel 63 is provided with a threshing / cutting clutch switch 67 for operating power on / off of the cutting unit 3 and the threshing unit 6.

  The steering lever 59 is supported so as to be capable of swinging back and forth and swinging left and right. The cutting part 3 is lifted and lowered by the swinging operation, and the vehicle body is turned left and right by the swinging operation. The control unit described later performs the lifting control of the cutting unit 3 and the steering control of the vehicle body.

  The grip formed on the upper part of the multi-steer lever 59 is provided with a pair of upper and lower push-operated switches (four in total). A pair of upper and lower momentary operation push-type switches arranged on the right side has a reel up switch 68 as an upper switch and a reel down switch 69 as a lower switch, and raises and lowers the take-up reel 17 ( (See FIG. 15). It should be noted that a pair of upper and lower momentary operation push-type switches arranged on the left side are such that the upper switch is the reel forward movement switch 65 and the lower switch is the reel rearward movement switch 70, Do.

  In the central portion of the auger remote control 64, auger manual switches 71, 72, 73, and 74, which are push-operated switches that perform a momentary operation, are installed at the left and right and top and bottom locations, respectively. The left and right switches are an auger left turn switch 71 and an auger right turn switch 72 that perform a left and right turn operation of the auger, respectively, and the upper and lower switches are an auger up switch 73 and an auger down switch that perform an up and down drive operation of the auger, respectively. 74.

  The auger remote control 64 is provided with an auger automatic switch 76 for executing auger turning automatic for automatically turning the auger to a predetermined position by a control unit described later at the center of the auger manual switches 71, 72, 73, 74. In addition, a turning position changeover switch 77 for designating a turning destination of the auger 9 by the auger turning automatic is arranged above the auger remote control 64 (see FIG. 16).

  17, on the input side of the control unit 75, the auger automatic switch 76 arranged on the auger remote control 64, the auger manual switches 71, 72, 73, 74, and the left / right turning position of the auger 9 are shown. An auger turning potentiometer 78 for detecting, an auger upper limit switch 79 for detecting that the auger 9 is moved to the highest position by the auger cylinder 29, the auger rest switch 56, and the operation of the multi steering lever 59 in the front-rear direction. A multi-lifting potentiometer 81 for detecting a position, a reel raising switch 68 for detecting a raising operation of the take-up reel 17, a reel lowering switch 69 for detecting a lowering operation of the take-up reel 17, and the threshing / reaping clutch switch 67 and a threshing / cutting clutch potentio 8 that detects the position of the threshing / cutting clutch. And a lift potentiometer 82 for detecting the elevation height of the main body of the cutting unit 3 as a height detection means for detecting the relative height with respect to the traveling machine body 2 on the input side of the control unit 75. And a reel height potentiometer 83 for detecting the elevation height of the take-up reel 17 with respect to the cutting frame 13 is connected.

  On the other hand, on the output side of the control unit 75, the auger motor 28, an auger valve 86 for expanding and contracting the auger cylinder 29 by supplying and discharging hydraulic oil, and the lift cylinder 21 by supplying and discharging hydraulic oil are provided. A lift valve 88 that extends and contracts, a reel valve 89 that expands and contracts the reel cylinder 24 by supplying and discharging hydraulic oil, an alarm horn 87, and a threshing / cutting clutch motor 91 that performs an on / off operation of the threshing / cutting clutch. Is connected.

  The control unit 75 is operated by an auger automatic storage control in which the auger automatic switch 76 is pushed to the position where the auger rest 32 is turned and swung up and down to the storage positions A and B, or the turning position changeover switch 77 is operated. The auger automatic control is executed to execute the auger automatic turning control to turn left and right to the selected grain right position D, right rear position E or right left position F.

  In the auger automatic control, the auger 9 is first driven up to the highest ascent position of the auger 9 where the auger upper limit switch 79 is pushed, and is driven to turn right and left to a predetermined position in this state. When the auger is driven down to a predetermined height, the auger 9 is automatically operated to a predetermined position. At this time, the control unit 75 is configured to determine the storage positions A and B of the auger 9 when the auger automatic storage control is executed by the auger setting control.

  That is, the control unit 75 controls the automatic auger storage so that the auger 9 is stored in the first storage position B when the switching of the auger rest 32 to the first receiving position is detected by the auger rest switch 56. On the other hand, when the switching of the auger rest 32 to the second receiving position is detected by the auger rest switch 56, the auger automatic storage control is performed so that the auger 9 is stored in the second storage position A. Is configured to run.

  In executing such an auger automatic control, the control unit 75 of the present invention detects the switching of the auger rest 32 to the first receiving position by the auger rest switch 56 and the relative position of the take-up reel 17 with respect to the traveling machine body 2. When the actual height is equal to or higher than the predetermined height, even if the auger automatic switch 76 is operated, the execution of the auger automatic storage control is prohibited, and the auger rest switch 56 switches the auger rest 32 to the second receiving position. When the relative height of the take-up reel 17 with respect to the traveling machine body 2 is equal to or higher than the predetermined height, the auger automatic storage control is executed according to the operation of the auger automatic switch 76. When the relative height of the take-up reel 17 with respect to the auger 9 is equal to or higher than a predetermined height, the automatic storage control of the auger 9 is prohibited. There automatic storage control of the second storage position A no is a possibility of collision with take-reel 17 would be acceptable, as a result, it is possible to avoid a decrease in workability.

  In addition, when the auger automatic storage control is performed so that the auger 9 is stored in the first storage position B, the control unit 75 prohibits the raising operation of the take-up reel 17 during the auger automatic storage control. In this way, it is possible to avoid the automatic storage control of the auger 9 from being stopped based on the raising of the take-up reel 17 during the automatic auger storage control. As a result, the auger 9 is allowed to run without being stored. Such inconvenience can be prevented.

  Further, the control unit 75 outputs an alarm when automatic auger storage control is not executed even when the auger automatic switch 76 is operated. In this way, the operator can be prompted to lower the take-up reel 17 or to re-operate the auger automatic storage control.

  The control unit 75 executes auger manual turning control for turning the auger 9 left and right and swinging up and down by the auger manual switches 71, 72, 73 and 74. Specifically, while the pushing operation of the auger raising switch 73 is detected, the auger 9 is driven to rise, the auger upper limit switch 79 detects the highest raising position of the auger 9, and the auger left turning switch 71 or While the pushing operation of the auger right turn switch 72 is detected, the auger 9 is driven to turn left and right. However, when the auger rest switch 56 detects the switching of the auger rest 32 to the first receiving position. The manual lowering operation of the auger 9 is prohibited and an alarm is output during the manual lowering operation. If it does in this way, it can prevent that the auger 9 contacts the pick-up reel 17 at the time of manual operation.

  Hereinafter, automatic auger storage control and auger manual control according to an embodiment of the present invention will be described with reference to FIGS. 18 and 19.

As shown in FIG. 18, in the auger automatic storage control, first, the presence / absence of an automatic storage operation is determined (S11). If this determination result is present, it is determined whether the auger rest switch 56 is ON / OFF (S12). . When this determination result is ON , since the auger 9 is automatically stored in the second storage position A where there is no possibility of contact with the reel 17, the auger automatic storage control is executed (S13).

On the other hand, if it is determined that the auger rest switch 56 is OFF , the auger 9 is automatically stored in the first storage position B where the auger 9 may come into contact with the reel 17. The relative height is determined (S14), and if the determination result is equal to or higher than the predetermined height, an alarm is output without executing the auger automatic storage control (S15). On the other hand, when the relative height of the take-up reel 17 with respect to the traveling machine body 2 is less than the predetermined height, the auger automatic storage control is executed (S13). The raising operation of the cutting unit 3 is prohibited (S16).

  As shown in FIG. 19, in the auger manual control, first, manual operation of the auger 9 is determined (S21, S22). If it is determined that the manual lowering operation of the auger 9 has been performed, the auger rest switch 56 is turned on. / OFF is determined (S23). If this determination result is OFF, the auger 9 is unlikely to come into contact with the reel 17, so the auger 9 is lowered (S24).

  On the other hand, if it is determined that the auger rest switch 56 is ON, the auger 9 may come into contact with the reel 17, so that an alarm is output without lowering the auger 9 (S25). If it is determined that an auger manual operation other than the lowering operation has been performed, the auger 9 is moved in the operation direction (S26).

  In this embodiment, when the auger upper limit switch 79 breaks down, there is a possibility that the auger 9 may start turning without being raised during the auger automatic storing operation or the auger automatic turning operation. ing.

The first countermeasure is a software countermeasure. When the auger upper limit switch 79 is ON (upper limit detection state) during an auger automatic storing operation or an auger automatic turning operation, one or more of the following is selected. Run.
1) Output an alarm.
2) Increase output for a predetermined time even if the upper limit is reached.
3) The turning operation is started only when it is automatically operated again.

  The second countermeasure is a hardware countermeasure, and the auger upper limit switch 79 is constituted by a two-system switch. The two-system switch has two contacts. For example, one contact is OFF and the other contact is ON except when an upper limit is detected, and one contact is ON and the other contact is OFF when an upper limit is detected. It becomes. According to the auger upper limit switch 79 composed of such a two-system switch, when a trouble such as a switch failure, a disconnection of a harness or a short circuit occurs, the two contacts do not switch in an inverted state, so the trouble can be easily generated. It is possible to judge, output an alarm, and prohibit execution of automatic control.

  According to the present embodiment configured as described, when the switching of the auger rest 32 to the first receiving position is detected by the auger rest switch 56, the control unit 75 detects that the auger 9 is in the first storage position. When the auger automatic storage control is executed so as to be stored in B, while the auger rest switch 56 detects the switching of the auger rest 32 to the second receiving position, the auger 9 is in the second storage position A. In addition, the auger automatic storage control is executed so that the auger rest 32 is switched to the first receiving position by the auger rest switch 56, and When the relative height of the take-in reel 17 is equal to or higher than the predetermined height, even if the auger automatic switch 76 is operated, the auger automatic storage control is executed. If the switching of the auger rest 32 to the second receiving position is detected by the auger rest switch 56 and the relative height of the take-up reel 17 with respect to the traveling machine body 2 is equal to or higher than a predetermined height, the auger Since the auger automatic storage control is executed in accordance with the operation of the automatic switch 76, the automatic storage control of the auger 9 is prohibited when the relative height of the take-up reel 17 with respect to the traveling machine body 2 is a predetermined height or more. However, automatic storage control to the second storage position A where the auger 9 is unlikely to collide with the take-in reel 17 is allowed, and as a result, deterioration in workability can be avoided.

  Further, when the auger 9 is controlled so that the auger 9 is stored in the first storage position B, the control unit 75 prohibits the raising operation of the take-up reel 17 during the auger automatic storage control. The automatic storage control of the auger 9 can be prevented from being stopped based on the raising of the take-up reel 17 during the storage control, and as a result, the inconvenience of running the machine body without the auger 9 being stored is prevented. Can do.

  Further, since the control unit 75 outputs an alarm when the auger automatic storage control is not executed even when the auger automatic switch 76 is operated, the control unit 75 outputs an alarm. The operation can be prompted.

  Of course, the present invention is not limited to the configuration of the above embodiment, and various additions and modifications can be made within the scope of the claims. For example, in the embodiment, during the automatic storage control to the first storage position, the raising operation of the take-up reel and the cutting unit is prohibited, but the raising operation to a height at which there is no possibility of contact with the auger is performed. It may be allowed.
