An embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a side view of a combine equipped with a granular material discharging apparatus according to an embodiment of the present invention, and FIG. 2 shows a vertical side view of a horizontal discharge auger of the combine of FIG.
The combine includes a traveling device 1, an operation seat 9 provided at an upper front portion of the traveling device 1, a threshing device 2 provided above the traveling device 1, a cutting unit 3 provided in front of the threshing device 2, and a threshing device 2. Glen tank 4 provided on the side, vertical cerealing device 5 for discharging grains in the grain tank 4, horizontal discharge auger 6, and auger receiver 43 that supports the horizontal discharge auger 6 when the horizontal discharge auger 6 is not used Etc.

  The horizontal discharge auger 6 is configured to be divided and formed by a cylindrical fixed auger 7 connected to the vertical cerealing device 5 and a cylindrical moving auger 8 attached to the fixed auger 7 so as to be stretchable. A connecting portion between the base portion of the fixed auger 7 and the vertical cerealing device 5 is known, and the tip of the horizontal discharge auger 6 is configured to be movable up and down and turn around the axis of the vertical cerealing device 5. The fixed auger 7 is provided with a fixed auger spiral 10. The fixed auger spiral 10 is mounted on an intermediate bearing portion 11 provided on the fixed auger 7.

  The structure for moving the moving auger 8 is arbitrary. For example, an outer bearing member 12 is provided on the outer peripheral portion of the fixed auger 7, and the distal end of the telescopic operating shaft member 13 is pivoted on the outer bearing member 12. The telescopic operation shaft member 13 is screwed with an expansion / contraction receiving member 15 provided in an arbitrary portion of the moving auger 8, and the base side of the telescopic operation shaft member 13 is a motor provided on the outer periphery of the fixed auger 7. The expansion / contraction operation shaft member 13 is rotated by the drive member 16 and the expansion / contraction receiving member 15 is reciprocated in the length direction to expand / contract the movable auger 8 with respect to the fixed auger 7.

  The moving auger 8 is provided with an expansion / contraction helix 17, and the expansion / contraction helix 17 rotates to convey the grain. The horizontal discharge auger 6 is rotatably provided with a grain discharge section 21 at the tip of the auger having an auger grain discharge port 21a that rotates left and right within an angle within a predetermined range in the circumferential direction with respect to the axial direction. ing.

  The grain discharging unit 21 at the tip of the auger is attached to the tip of the moving auger 8 with a cylindrical member concentric with the moving auger 8 (lateral discharge auger 6). It has a discharge port 21a in a direction that intersects with it. The entire grain discharger 21 at the tip of the auger rotates with respect to the moving auger 8.

  FIG. 3 shows a front view of the grain discharge portion 21 provided at the tip of the horizontal discharge auger 6 of the granular material discharge apparatus according to one embodiment of the present invention, and FIG. 4 shows the horizontal discharge auger of FIG. 6 is a side sectional view of the tip portion of FIG. FIG. 5 shows a diagram of the operation unit 53 provided in the operation seat 9 of the combine of FIG. FIG. 6 is a control block diagram showing a connection state of the control unit of the granular material discharging apparatus of FIG. Further, FIG. 7 shows a monitor device provided in the operation seat 9 of the combine of FIG.

  Although the structure of the right-and-left rotation mechanism of the grain discharger 21 at the tip of the auger is arbitrary, for example, a fixed gear 25 having the rotation center axis 51 of the grain discharger 21 as an axis is provided. Is engaged with a rotating gear 27 of the turning motor 26.

  Since the rotation gear 27 of the turning motor 26 is meshed with the fixed gear 25, when the turning motor 26 is driven forward and reverse, the rotation gear 27 integrated with the turning motor 26 rotates. The grain outlet 21 a is integral with the grain outlet case 28, and the turning motor 26 is provided in the grain outlet case 28. In this way, the turning motor 26 itself rotates together with the auger grain outlet 21a. The grain discharge part 21 at the tip of the auger is rotated with respect to the moving auger 8, and as a result, the opening direction of the auger grain discharge port 21a is changed.

  In the granule discharging apparatus in which the grain discharging portion 21 provided at the tip of the moving auger 8 of the auger 6 for discharging the grain rotates left and right by a predetermined angle in a direction orthogonal to the axis of the auger 6, the grain The discharge unit 21 is provided with limit switches 48 and 49 (FIG. 3) for detecting the limit position of the left-right rotation, and a notification device 52 (in FIG. 5) for notifying information of the limit position detected by the limit switches 48 and 49. As shown in FIG. 5, the control unit 40 (see FIG. 5) is provided in the operation unit 53 provided in the operation seat 9, and further controls the operation of the notification device 52 based on the information on the limit position. 6).

  As shown in FIG. 3, a right upper limit switch 50 is provided in addition to the right limit limit switch 48 and the left limit limit switch 49 at the limit position of the left and right rotation of the grain discharging unit 21. These limit switches 48, 49, 50 are connected to the vicinity of the rotation center axis 51 of the grain discharging unit 21.

  The turning motor 26 of the grain discharging unit 21 transmits power to the rotating gear 27 via the drive shaft 27 a, and the rotating gear 27 is engaged with the fixed gear 25. When the turning motor 26 is driven, the rotary gear 27 is rotated and the limit switches 48, 49, 50 and the grain discharging unit 21 interlocked with the rotating gear 27 are rotated. When the rotation of the grain discharging unit 21 reaches the limit position. When the spring 60 hits the cam 30, the right or left limit limit switches 48 and 49 are turned on, the control device 40 is activated, and the operation unit 53 provided in the operation seat 9 as an example of the notification device 52. The lamp 52a is turned on.

Further, instead of the lamp 52a, a buzzer may be provided to sound a buzzer, or a speaker may be provided to output sound from the speaker, or the monitor 52b (FIG. 7) may be used for display. The display on the monitor 52b may be a character, a figure, or a symbol, and is not particularly limited as long as it is displayed so as to be understood by an operator by an image.
Further, as the notification device 52, a lamp 52a, a monitor 52b, a buzzer, a speaker (sound), or the like may be used in combination.

  Usually, when the left-right rotation of the grain discharge unit 21 exceeds the limit position, the grain may be clogged at the grain discharge port 21a. However, by adopting this configuration, when the left-right rotation of the grain discharging unit 21 reaches the limit position, the lamp 52a of the operation unit 53 provided in the operation seat 9 is turned on, a buzzer sounds, or By being displayed on the monitor 52b, the operator can immediately understand, so that the operability of grain discharge is improved and the grain can be prevented from being clogged at the grain outlet 21a. In addition, when the buzzer is provided or the sound is output from the speaker, the limit position of the left and right rotation of the grain discharging unit 21 can be known by sound and sound, so that the operator can visually observe the side discharging auger 6 portion. With this, grain can be discharged. Moreover, since it does not give anxiety to an operator when notifying by voice, the operator can perform the grain discharging operation with peace of mind.

  In addition, the grain discharging unit 21 at the tip of the auger can be rotated to a position directly above the moving auger 8 while the grain discharging operation is stopped, and the switch for stopping the grain discharging part 21 at the position immediately above. When the spring 60 of the upper limit switch 50 is in contact with the cam 30, the upper limit switch 50 is turned on. Therefore, when the grain discharging part 21 at the tip of the auger is rotated left and right by a predetermined angle or more, the grain can be prevented from leaking from the auger grain discharging port 21a during the movement of the machine body. On the other hand, if the grain discharging part 21 at the tip of the auger is rotated left and right up to a predetermined angle during the grain discharging operation, it becomes a cause of grain clogging.

  As described above, the moving auger 8 of the lateral discharge auger 6 is provided with a grain discharging portion 21 at the tip of the auger that rotates left and right in the circumferential direction with respect to the axial direction. When the grain discharging unit 21 is rotated left and right about the axis center of the moving auger 8, the grain discharging direction can be changed. This is a change of the discharge position similar to the case where the grain discharger 21 at the tip of the auger is turned around the vertical cerealing device 5, and the operation is simple and the fine adjustment is easy. Therefore, the operability and workability are further improved.

  Further, as shown in FIGS. 3 and 4, the ramp 52 a may be provided at the tip of the moving auger 8. According to this configuration, when the left-right rotation of the grain discharging unit 21 reaches the limit position, the lamp 52a provided at the leading end of the moving auger 8 is turned on, so the operator visually observed the leading end of the horizontal discharging auger 6. Work can be done as it is, and grain discharge workability is good.

  Further, as described above, not only the lamp 52a but also a buzzer, a speaker, a monitor 52b, and the like may be provided at the distal end portion of the moving auger 8, or these may be used in combination. Further, the position where the lamp 52a and the like are provided is not limited to the tip of the moving auger 8, but may be the central portion of the lateral discharge auger 6 or other positions as long as it can be recognized by an operator in the vehicle or outside the vehicle.

FIG. 8 shows a side sectional view of the distal end portion of the horizontal discharge auger 6 of the granular material discharge apparatus according to another embodiment of the present invention, and FIG. 9 shows a front view of the grain discharge portion 21 of FIG. Show.
In the example shown in FIG. 3, the limit switches 48, 49, and 50 are provided. However, in the example shown in FIG. That is, the configuration is simplified compared to the example of FIG.

  As shown in FIGS. 8 and 9, a position sensor 55 that detects the left-right rotation angle of the grain discharge unit 21 is provided in the grain discharge unit 21, and is provided in the operation seat 9 based on the data of the left-right rotation angle. The color of the lamp 52 a (FIG. 6) of the operation unit 53 is changed so that the left and right rotatable range of the grain discharging unit 21 can be understood.

  As shown in FIGS. 8 and 9, gears 24 and 25 are attached in parallel to a rotation center shaft 51 fixed on the center axis of the moving auger 8 at the tip of the moving auger 8. A grain outlet case 28 is provided at the tip of the moving auger 8 via a bearing 29 so as to be rotatable. A turning motor 26, a rotary gear 27 driven by a motor 26 around a drive shaft 27a, and a position sensor 55 are fixed to the grain outlet case 28. A central shaft 41 a of the fan-shaped gear 41 is rotatably provided at the axial center of the position sensor 55, the fan-shaped gear 41 is engaged with the gear 24, and the rotary gear 27 is engaged with the gear 25.

  Accordingly, when the rotary gear 27 is driven by the drive of the motor 26, the rotary gear 27 rotates around the stationary gear 25. Therefore, the grain drainage with the rotary motor 26 integrated with the rotary gear 27 and the position sensor 55 fixed thereto is fixed. The outlet case 28 rotates about the rotation center shaft 51. The fan-shaped gear 41 is engaged with the gear 24 by the rotation of the grain outlet case 28 and is rotated about the central axis 41a while changing the rotation angle with respect to the axial center of the position sensor 55. Since the position sensor 55 detects a change in the rotation angle of the sector gear 41 with respect to the axial center of the position sensor 55, the position sensor 55 can detect the rotation position of the grain outlet 21 a relative to the rotation center shaft 51. .

  And when the left-right rotation of the grain discharge part 21 approaches a limit position, the control apparatus 40 (FIG. 6) will act | operate and the color of the said lamp | ramp 52a will be changed. For example, what is necessary is just to change from blue to red in steps according to a left-right rotation angle. In addition to changing the color of the lamp 52a, the lamp 52a may be blinked, or the monitor 52b, buzzer, sound, etc. may be used in combination.

By adopting this structure, the color of the lamp 52a provided in the operation unit 53 of the operation seat 9 is changed according to the left-right rotation angle of the grain discharge unit 21, thereby turning the grain discharge unit 21 left and right. The change of the angle can be known, and the left-right rotation angle of the grain discharging unit 21 can be easily understood.

  The ramp 52a may be provided at the tip of the moving auger 8. That is, the color of the lamp 52 a provided on the moving auger 8 is changed so that the range in which the grain discharging unit 21 can be rotated in the left-right direction can be understood.

  By adopting this configuration, by changing the color of the lamp 52 a provided on the moving auger 8 according to the horizontal rotation angle of the grain discharge unit 21, the change in the horizontal rotation angle of the grain discharge unit 21. It becomes easy to understand the left-right rotation angle of the grain discharging unit 21. Further, since the ramp 52a is provided in the moving auger 8 portion, the operator can work while viewing the moving auger 8 portion, and the grain discharging workability is good.

  Further, from the data of the position sensor 55 that detects the left-right rotation angle of the grain discharge unit 21, the range in which the left-right rotation of the grain discharge unit 21 can be displayed is displayed on the monitor 52 b (FIG. 7) provided in the operation seat 9. Also good. For example, information such as “how much the grain discharging unit 21 can rotate left and right” and “where the grain discharging unit 21 is currently located” is displayed. By adopting this configuration, the angle of the left and right rotation of the grain discharger 21 can be understood by looking at the monitor 52b, so that the operability of grain discharge is improved.

  Further, as shown in FIG. 5, a down button 56 may be provided on the operation unit 53. When the directly below button 56 is pressed, the grain discharge port 21a of the grain discharge unit 21 is configured to face directly below (FIG. 9).

  When the automatic storage switch 57 provided in the operation seat 9 is pressed, the horizontal discharge auger 6 is stored in the auger receiver 43, and the grain discharge port 21a is rotated 180 degrees and is directed straight upward. As a result, spillage can be prevented.

  Next, when the discharge operation is performed again, conventionally, the manual rotation switch 59 (FIG. 5) is operated in the operation for directing the tube tip of the moving auger 8, that is, the grain discharge port 21a (FIG. 9). Was pointing down. However, it is difficult to direct the grain outlet 21a directly below, and the workability differs depending on the skill level of the worker. That is, even if a skilled worker can immediately point the grain outlet 21a directly below, a beginner cannot successfully point the grain outlet 21a right below. However, by adopting this configuration, since the operation button 53 is provided with the directly below button 56, the grain discharge port 21a is configured to be directly below by simply pressing the directly below button 56. Anyone can easily point the grain outlet 21a of the grain outlet 21 directly below.

  Further, as shown in FIG. 8, by providing the friction plates 58 and 58 on both surfaces of the fixed gear 25, the friction plates 58 and 58 press the fixed gear 25 with an appropriate braking force by the nut 61, and in an abnormal state. It can be set as the structure which slides rotation of the grain discharge port case 28, and idles. That is, when the helical shaft 17a rotates, the telescopic spiral 17 rotates, but the rotation center shaft 51 of the grain discharging unit 21 is not connected to the helical shaft 17a. Therefore, when the grain outlet case 28 comes into contact with an obstacle during rotation, the friction plates 58 and 58 remain on the plane of the fixed gear 25 even if the fixed gear 25, the motor 26, etc. rotate together with the rotation center shaft 51. It is possible to avoid damage to the fixed gear 25, the turning motor 26, and the like.

  Further, the lamp 52a shown in FIG. 4 or FIG. 5 may be changed to a buzzer so that a buzzer sound for notifying abnormality is sounded when the idling is performed. The lamp 52a may be left as it is without the buzzer, and may be displayed on the monitor 52b (FIG. 7) or notified by voice. Even when a motor drive output command is output from the control device 40 (FIG. 6) to the turning motor 26, the input from the position sensor 55 that detects the left-right rotation angle of the grain discharging unit 21 does not change, that is, in an abnormal state. This is a configuration that warns by sounding a buzzer.

  Conventionally, when the grain discharging unit 21 at the tip of the horizontal discharging auger 6 is rotating, if it interferes with another object, the fixed gear 25 is damaged or the turning motor 26 is burned out. was there. However, according to the present embodiment, the friction plate 58 is pushed from both sides of the fixed gear 25 with an appropriate brake force, and in an abnormal state, the rotation of the grain outlet case 28 is slid to idle, and is idled. Since the buzzer sound for notifying the abnormality is sounded together when there is a malfunction, problems such as damage to the fixed gear 25, the turning motor 26, the brake plate, etc. are eliminated.

  The present invention is not limited to agricultural machines, but may be used in other technical fields such as industrial machines as a granular material discharging device that discharges powders to the outside.
