Description

  The present invention relates to a general-purpose combine that supports an auger on a traveling machine body so that it can turn left and right and can swing up and down.

  A cutting part is connected to the front side of the traveling machine body so that it can be raised and lowered, and a reel is supported to the cutting part so that it can be raised and lowered. A general-purpose combine described in Patent Document 1 provided with a storage position for storage is known.

JP 2007-71 A

  The general-purpose combine described in the above document installs a short auger with respect to the entire length of the vehicle body and stores it in the storage position in order to prevent the auger and reel from coming into contact even when the reel is raised and positioned at a predetermined height or higher. The leading end of the auger is positioned behind the reel at a height higher than the predetermined level. For this reason, when the total length of the vehicle body is short, the length of the auger may be insufficient and the grain discharging operation may not be performed efficiently.

  The present invention supports the auger on the traveling machine body so that the auger can turn left and right and can swing up and down, and the ascending reel is stored in the storage position. An object of the present invention is to provide a general-purpose combine that can sufficiently secure the length of the auger in order to efficiently prevent contact with the auger.

  In order to solve the above-described problems, first, the invention is such that the cutting unit 3 is connected to the front side of the traveling machine body 2 so as to be movable up and down, and the reel 17 is supported on the cutting unit 3 so as to be movable up and down. The auger 9 is lowered and stored to a position where the auger 9 wraps in a side view with the reel 17 positioned at a predetermined height or more as the mowing unit 3 and the reel 17 rise. A first storage position B where the auger 9 is wrapped with the planar view reel 17 and a second storage position which is located on the left and right outside of the first storage position B so that the auger is not wrapped with the planar view reel. It is characterized in that at least two storage positions with A are provided.

  Secondly, the tip of the auger 9 stored in the second storage position A with respect to the narrow guide 16 that is positioned on the outermost end side during reaping operation and separates the uncut-side grain straws to the left and right outside. However, the second storage position A is arranged so as to be located behind the front end of the narrow guide 16 and inside the left and right sides of the outermost end of the narrow guide 16.

  Third, an auger rest 32 for receiving and supporting the auger 9 is provided, and the auger rest 32 is provided at a first receiving position for receiving the auger 9 stored in the first storage position B and a second storage position A. It is characterized in that it is supported on the traveling machine body 2 side so as to be switchable to at least two places with the second receiving position for receiving the stored auger 9.

  According to the above configuration of the present invention, since the auger and the reel do not wrap in a plan view by switching the auger to the second storage position, the auger can be extended to the reel side in front of the traveling machine body. In addition to avoiding contact with the auger due to the drive of raising the reel, the auger can be arranged so as to wrap with the reel in plan view by switching the auger to the first storage position. At times, the vehicle width direction of the traveling machine body can be made compact.

  In addition, the tip of the auger stored in the second storage position is positioned on the outermost end side during cutting operation, and the tip of the auger stored in the second storage position is If the second storage position is arranged so as to be located behind the front end and on the left and right sides of the outermost end of the narrow guide, the auger at the second storage position can be used even when there is an obstacle in the field for cutting. Since the narrow guide comes in contact with the obstacle before the tip of the hopper, damage due to the auger coming into contact with the obstacle can be prevented, and the operator visually confirms that the narrow guide on the field side does not come into contact with the obstacle. If it confirms, since contact with an auger and an obstruction can also be prevented, workability | operativity improves.

  An auger rest for receiving and supporting the auger is provided, and the auger rest is received by a first receiving position for receiving the auger stored in the first storage position and a auger stored in the second storage position. If it is supported on the traveling machine side so that it can be switched to at least two positions with two receiving positions, the auger can be reliably placed and supported on the auger receiver at a predetermined position even when the storage positions are close. In addition, it is not necessary to provide an auger rest for each of a plurality of storage positions of the auger, and the cost can be reduced.

Hereinafter, embodiments of the present invention will be described based on illustrated examples.
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 as a traveling unit, and is movably connected to the front of the traveling machine body 2 to perform 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 supported by a pair of left and right support arms 23 supported by the feeder 12 via a support member 22 so as to be swingable in the vertical direction so as to be rotatable about its own axis. A reel cylinder 24 is installed between the support arm 23 on one side (left side in the illustrated example) and the cutting frame 13 to raise and lower the scraping reel 17 with respect to the main body of the cutting unit 3 by expansion and contraction. The support arm 23 on the other side 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 way, the cereals guided between the left and right side walls of the reaping frame 13 by the left and right dividers 14 are cut by the stocking reel 17 and the cutting blade 18 while the entire cereal side is reaped. It is scraped from the front side of the part 3 and further introduced into the feeder 12 by the scraper 19 behind the cutting part 3. 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 scraping reel 17 are both lowered to the lowest position, the main body of the cutting unit 3 comes close to the field scene. The scraping reel 17 is in a state of being 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.

  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 includes a travel receiving position (first receiving position) b for receiving the midway part of the auger 9 stored in the travel storage position B and a 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, a work receiving position (second receiving position) a.

  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. The auger 9 thus formed has a plan view of the auger 9 and the take-up reel 17 so as to prevent interference between the auger 9 and the take-up reel 17 by causing the tip of the auger 9 to protrude in the width direction of the machine body. Is in a non-wrapping state (see FIG. 2).

  In addition to this, the tip 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 a narrow guide in the unfolded posture described above in plan view as shown in FIG. 16 is located rearward from the front end of 16, and is located closer to the take-up reel 17 (right and left inside) than the outermost end of the narrow guide 16 in the unfolded posture in plan view. 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 protruding portion near the tank 7, it protrudes further upward, and by attaching a locking plate 34 integrally to the back side of the auger rest 32 by welding or the like, a U-shaped lower portion opened in a side view is opened. A hook portion 36 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 fixed to the middle part of the threshing side connection frame 43 by welding or the like. 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 the lower side so that both are engaged, and the augerrest 32 is moved to the travel receiving position b described above. Then, 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. In a, 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.

  Therefore, when the augerrest 32 is switched to the work receiving position a, 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 moved to the travel receiving position b. When the switch is made, the contact between the operating plate 57 and the augerest switch 56 is released, and the augerest 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 travel receiving position b or the work receiving position a.

  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 b, the auger rotated left and right at the travel storage position can be placed and stored, and the auger rest 32 can be stored. Is fixed at the work receiving position a, 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 augerest 32 is switched from the travel receiving position b to the work receiving position a or from the work receiving position a to the travel receiving position b, the augerest 32 is also removed. Since the connection arm 51 is always connected to the support device 33 side, the hook portion 36 of the augerrest 32 can be prevented from unexpectedly coming off from the support stay 38 when the receiving position of the augerest 32 is switched.

  Further, the augerrest 32 is configured to be able to swing left and right in a circular arc shape with the support device 33 side of the connecting arm 51 as a fulcrum and can be fixed by a lock pin 52 at a predetermined storage position. 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. The amount of turning when switching 32 to the work receiving position a and the traveling receiving position b is small, and 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 operated auger 9 is close to the storage positions A and B. Thus, it can be securely placed and stored at the storage positions A and B at predetermined positions.

  The augerest 32 is supported by the support device 33 at a position near the control unit 4 between the boundary between the threshing unit 6 and the grain tank 7, and the support device 33 is reversed by the support 37 and the support stay 38. Since it is formed in an L shape, it is arranged so that the lower side of the work receiving position a 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. The augerest 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.

  Note that the augerest 32 eliminates the switching mechanism described above, particularly when the storage positions A and B are sufficiently separated from each other and there is no risk of lowering to the unintended storage positions A and B. A wedge-shaped work receiving portion (not shown) for receiving the auger 9 operated at the work storage position A and a wedge-shaped travel receiving portion (not shown) for receiving the auger 9 operated at the traveling storage position B. May be formed in a W-shape integrally provided.

Next, based on FIGS. 14 to 17, the configuration of a control unit that controls the lifting and lowering of the main body of the cutting unit and the take-up reel, the up-and-down swinging of the auger, and the left-right rotation will be described.

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 ( FIG. 15). It should be noted that a pair of upper and lower momentary push-type switches arranged on the left side have a reel forward movement switch 65 on the upper side and a reel rearward movement switch 70 on the lower side. I 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 detects the pushing operation of the auger automatic switch 76, thereby turning the auger 9 at the discharge position to the storage position A and B by turning left and right and swinging up and down to the auger rest position. Control or auger automatic turning control for turning the auger 9 in the storage position to the left or right to the grain discharging position selected from the right position D, right back position E or right position F selected by the turning position changeover switch 77 It is configured to perform automatic auger control.

  In the auger automatic control, the auger 9 is first driven up to the highest ascending position of the auger where the auger upper limit switch 79 is pushed, and is rotated left and right to a predetermined position in this state. The auger 9 is automatically operated to a predetermined position by causing the descent drive to move to a predetermined height.

  At this time, the control unit 75 determines the storage positions A and B of the auger 9 when the automatic auger storage control is executed by the auger setting control. Specifically, when the auger rest switch 56 is ON, the storage position of the auger 9 when the automatic auger storage control is executed is switched to the work storage position A, and when the auger rest switch 56 is OFF, the auger automatic storage is performed. When the control is executed, the storage position of the auger 9 is switched to the travel storage position B.

  When the auger rest switch 56 is OFF and the lift reel 82 and the reel height potentiometer 83 detect that the take-up reel 17 is higher than a predetermined position when the automatic auger storage control is executed. The auger automatic storage control is cancelled.

  The control unit 75 can perform auger manual turning control in which the operator turns the auger 9 left and right and 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 turning switch 72 is detected, the auger 9 is driven to turn left and right.

  At this time, the left turn limit position of the auger 9 can be turned left to the work storage position A when the auger rest switch 56 is ON, and the traveling storage position B is set when the auger switch 56 is OFF. The left turn limit position is reached, and the left turn drive ahead of the travel storage position B is restricted.

  In addition, when it is detected that the auger 9 is between the traveling storage position B and the control unit side position C, the control unit 75 detects that the auger upper limit switch 79 is turned on and reaches the highest position of the auger 9. In this case, left and right turning is allowed only when the auger 9 is driven, and the auger 9 is controlled to move downward.

  Further, when it is detected that the auger 9 is in the range of the work storage position A, the travel storage position B, and the true right position D to the true left position F, the lowering operation of the auger 9 is permitted. At this time, even if it is detected that the auger 9 is in the traveling storage position B, it is detected by the lift potentiometer 82 and the reel height potentiometer 83 that the take-up reel 17 is higher than the predetermined position. In this case, the lowering drive of the auger 9 is configured to be restricted.

  Further, when it is detected by the above configuration that the control unit 75 is in the travel storage position B, which is the position where the take-up reel 17 and the auger 9 wrap in a plan view and can be driven downward. (The steering part side position C is assumed that the take-up reel 17 and the auger 9 do not wrap in a plan view), the ON of the auger upper limit switch 79 is not detected, and it is detected that the auger 9 is not the highest position. At this time, the raising drive of the take-up reel 17 is restricted.

  In addition, even when the scraping reel is operated to the highest position, the auger may be turned left and right if the auger is swung upward to a predetermined height that does not contact the auger.
