Description

  The present invention relates to a granular material discharging apparatus for discharging powdery particles such as soybeans, red beans, rice, wheat, buckwheat, and flour to the outside.

  Combine harvesters and granular material transport vehicles are equipped with a discharge auger that discharges the grains temporarily stored in the Glen tank to the outside, and the grains are discharged to trucks, containers, etc. by the discharge auger or packed in bags. After that, it is taken out and used. Usually, a spiral for conveying the grain is provided in the discharge auger, and the grain is discharged to the outside by rotating the spiral.

  However, when discharging the grain to the outside, it is concentrated at one place from the grain outlet of the discharge auger, so it is necessary to change the discharge position frequently, and the work is complicated and workability is not good . In addition, since the grain outlet of the discharge auger faces downward, there is a problem that the grain remaining in the auger falls when the discharge auger is stored in the auger receptacle.

Therefore, in Patent Document 1 below, a grain discharge device is proposed in which a grain discharge port that rotates left and right in a direction perpendicular to the axis of the auger is provided at the tip of the discharge auger.
Japanese Patent Laid-Open No. 2004-008088

  In the configuration described in Patent Document 1, the grain discharge port provided at the tip of the discharge auger rotates left and right in a direction perpendicular to the axis of the auger. Without concentrating on the location, it can be discharged evenly to every corner of the tank, making it easy to discharge. Moreover, since the grain discharge port provided at the tip of the discharge auger can be inverted and stored in the auger receiver, it is possible to prevent the grains from falling when stored in the auger receiver.

  However, if the grain outlet of the discharge auger is rotated beyond a predetermined angle and the grain is discharged in a state where this is forgotten, the grain may become clogged. In other words, it may become an obstacle to work. Moreover, it is necessary to operate so as not to exceed the angle at which the grain outlet is clogged so that the grain outlet of the outlet auger does not rotate too much to the left and right, and it cannot be said that the operability is good. Furthermore, even if the grain discharge port rotates too much to the left and right and exceeds the angle at which the grain discharge port is clogged, it is not easily understood by the operator.

  The subject of this invention is preventing the clogging of the grain outlet of a discharge auger, and improving the operativity and workability | operativity of a discharge auger.

The said subject of this invention can be achieved by employ | adopting the following structures.
According to the first aspect of the present invention, the grain discharge portion (21) provided at the tip of the auger (6) for discharging the grain rotates left and right at a predetermined angle in a direction perpendicular to the axis of the auger (6). In the granular material discharging apparatus, a sensor (55) for detecting a left-right rotation angle of the auger (6) and a notification for informing information on the left-right rotation angle of the auger (6) detected by the sensor (55). Determining the possible range of the horizontal rotation from the information on the horizontal rotation angle of the means (52) and the auger (6), and notifying the information on the possible range by the notification means (52), (6) It is a granular material discharge | emission apparatus which has a control means (40) which changes the said alerting | reporting content, when the range which can be rotated right and left approaches the limit.

In the invention according to claim 2, the grain discharging part (21) provided at the tip of the auger (6) for discharging the grain rotates left and right at a predetermined angle in a direction perpendicular to the axis of the auger (6). In the granular material discharging apparatus, a sensor (55) for detecting a left-right rotation angle of the auger (6), a sound generating means (52a) for generating sound, and the auger (6) detected by the sensor (55) And a control means (40) for determining a range in which the left-right rotation is possible based on the information on the left-right rotation angle in (2), and generating a sound by the sound generation means (52a) for the information on the possible range It is a granular material discharging apparatus.
As the sound generating means (52a), any means for generating sound such as a speaker can be used in addition to the buzzer.

According to the first aspect of the present invention, since the notification content of the notification means (52) changes according to the horizontal rotation angle of the grain discharger (21), the operator is limited in the horizontal rotation angle. Since the grain discharging operation can be performed while checking whether the value is close to the value, it is excellent in the grain discharging workability.
According to invention of Claim 2, since the change of the left-right rotation angle of a grain discharge part (21) can be understood with sound, the auger (6) was visually observed while listening and confirming the left-right rotation range. Since the grain discharging work can be performed as it is, the grain discharging workability is excellent.

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 shown in 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 and contraction operating shaft member 13 is rotated by the drive member 16 and the expansion and contraction receiving member 15 is reciprocated in the length direction to expand and 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 an auger tip discharge portion 21 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 at the tip.

  The auger tip discharge portion 21 has a cylindrical member concentric with the movable auger 8 (lateral discharge auger 6) attached to the distal end of the movable auger 8 so as to be freely rotatable only in the left-right direction, and intersects the axis of the movable auger 8. It has a directional outlet 21a. The entire auger tip discharge portion 21 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. A side sectional view of the distal end portion of the auger 6 of the body discharging apparatus is shown, and FIG. FIG. 6 is a block diagram showing a connection state of the control unit of the granular material discharging apparatus of FIG. FIG. 7 shows a monitor provided in the operation seat 9 of the combine.

  While the grain discharging operation is stopped, the auger tip discharging unit 21 can be rotated to a position directly above the moving auger 8, for example, and when the auger tip discharging unit 21 is rotated left and right by a predetermined angle or more, the machine body is moved. It is possible to prevent the grain from leaking from the auger grain outlet 21a. On the other hand, if the auger tip discharger 21 is rotated left and right up to a predetermined angle during the grain discharging operation, it may cause a grain clogging.

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

  The angle by which the grain discharging unit 21 rotates left and right in a direction perpendicular to the axis of the auger 6 is detected by a position sensor 55 provided in the grain outlet case 28, and the left and right rotation detected by the sensor 55 is detected. Information on the angle is notified by the notification device 52.

The range in which the left / right rotation is possible is determined from the information detected by the position sensor 55, the information of the possible range is notified by the notification device 52, and the notification content when the range in which the left / right rotation is possible approaches a limit. The control for changing is performed by the control device 40 shown in FIG.
In FIG. 5, a buzzer 52a is illustrated as an example of the notification device 52, but other lamps 52c (FIG. 6) may be used, and the present invention is not limited thereto.

  As shown in FIGS. 3 and 4, gears 24 and 25 are attached in parallel to a rotation center shaft 51 fixed on the center axis of the auger 6 at the tip of the cylinder 6 a of the auger 6. In addition, a grain outlet case 28 is provided at the tip of the cylindrical body 6a through a bearing 29 so as to be rotatable. A rotation motor 26, a drive gear 27 driven by the 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 sector gear 41 is rotatably provided at the axial center of the position sensor 55, the sector gear 41 is engaged with the gear 24, and the drive gear 27 is engaged with the gear 25.

  Therefore, when the drive gear 27 is driven by the drive of the motor 26, the drive gear 27 rotates around the stationary gear 25. Therefore, the grain outlet case in which the motor 26 and the position sensor 55 are fixed to the drive gear 27. 28 rotates around 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 with respect to the rotation center shaft 51. .

  About the information of the rotation angle of the grain discharge port 21a detected by the position sensor 55, the control device 40 operates the notification device 52 to notify, and when the left-right rotation angle of the grain discharge unit 21 approaches the limit position. The control device 40 is further operated to change the notification content.

  For example, from the data of the sensor 55 that detects the left-right rotation angle of the grain discharging unit 21, a range in which the left-right rotation is possible is provided in the operation unit 53 of the cockpit, for example, by an intermittent sound by a buzzer 52a. When the limit position of the left-right rotation of the discharge unit 21 approaches, the control device 40 performs control so that the sound interval is narrowed. According to this configuration, the operator can listen to whether the left / right rotation angle is close to the limit value or not by changing the interval of the intermittent sound according to the left / right rotation angle of the grain discharging unit 21. Can work while observing the horizontal discharge auger 6 and is excellent in grain discharge workability. In addition, the sound intensity may be changed, the sound pitch may be changed, or a different sound may be used. Furthermore, it is good also as a structure which can be recognized visually. For example, when the buzzer 52a is changed to the lamp 52c or the monitor 52b (FIG. 7) and the limit position of the left-right rotation angle of the grain discharging unit 21 approaches, the lamp 52c blinks or the display changes. good. A buzzer 52a, a lamp 52c, a monitor 52b, etc. may be used in combination.

  Further, instead of the buzzer 52a shown in FIG. 5, the range in which the left and right can be rotated may be notified by voice from the data of the sensor 55 that detects the left and right rotation angle of the grain discharging unit 21 using a speaker. And when the limit value of the left and right rotation angle approaches by the data from the detection sensor 55 of the left and right rotation angle of the grain discharging unit 21, a warning is given by voice, and when the limit value of the left and right rotation angle is reached, It is good also as the structure which notifies this by words. By adopting this configuration, the change in the left-right rotation angle of the grain discharger 21 can be understood by voice, so it is more detailed than the sound of a buzzer, etc. However, the operator can work while observing the horizontal discharge auger 6 and is excellent in grain discharge workability.

  Further, as shown in FIGS. 3 and 4, a camera 60 is provided in the grain discharge unit 21 of the horizontal discharge auger 6, and the grains are transferred from the grain discharge unit 21 to the grain container 61 (FIG. 9B). It is set as the structure which can understand the mode of the grain in the container 61 for grains when discharging | emitting. That is, by adopting this configuration, which is a configuration in which the image of the camera 60 provided in the grain discharge unit 21 is displayed on the monitor 52b of the operation seat 9, the state in the grain container 61 from the monitor 52b in the operation seat 9 Therefore, grain discharge workability and operability are improved.

  Moreover, in the granular material discharge | emission apparatus in which the grain discharge part 21 provided in the front-end | tip of the horizontal discharge auger 6 which discharges | emits a grain rotates right and left by a predetermined angle in the direction orthogonal to the axial center of the horizontal discharge auger 6, Even if the automatic storage switch 57 (FIG. 5) is pressed during the ejection of the grains, the automatic storage control may not be entered. The automatic storage switch 57 is a switch for storing the horizontal discharge auger 6 in the auger receiver 43 (FIG. 1) regardless of the position of the horizontal discharge auger 6. When the discharge clutch switch 59 is on, the automatic storage control 57 is configured not to enter the automatic storage control even if the automatic storage switch 57 is pressed. By adopting this configuration, even if the automatic storage switch 57 is pressed during the grain discharging operation, the automatic storage control is not entered, so that the horizontal discharge auger 6 is not automatically stored while dispersing the grains.

In FIG. 8, the side view of the combine which provided the granular material discharge | emission apparatus which is another Example of this invention is shown.
As shown in FIG. 8, in the horizontal discharge auger 6 that is inverted by 180 °, the grain discharge portion 21 provided at the tip of the horizontal discharge auger 6 that discharges the grain goes directly to the axis of the horizontal discharge auger 6. By rotating left and right at a predetermined angle, the grain can be discharged at any position at the storage position S of the horizontal discharge auger 6 as well as the extended position W of the horizontal discharge auger 6.

  By adopting this configuration, even in a combine auger in which the horizontal discharge auger 6 is inverted 180 ° upward, the grain discharge portion 21 is rotated left and right at a predetermined angle in a direction perpendicular to the axis of the horizontal discharge auger 6. Thereby, since the grain can be discharged not only at the overhanging position W of the horizontal discharge auger 6 but also at the storage position S of the horizontal discharge auger 6, the grain discharge workability is improved. In addition, since the horizontal auger 6 is simply inverted 180 ° to the W position, the time required for moving to the W position is shorter than in a configuration in which the auger is raised and then turned.

FIG. 9A shows a perspective view of a combine provided with a granule discharging apparatus according to another embodiment of the present invention, and FIG. 9B shows a perspective view of a grain container 61.
As shown in FIG. 9, the grain container 61 is provided with a transmitter 62, and the combiner is provided with a receiver 63 so that the distance from the transmitter 62 can be seen. Then, the transmitter 62 and the receiver 63 display whether the lateral discharge auger 6 reaches the grain container 61 on the monitor 52b (FIG. 7) of the operation seat 9. For example, the distance between the transmitter 62 and the receiver 63 may be displayed on the monitor 52b of the operation seat 9. Further, whether or not the horizontal discharge auger 6 reaches the grain container 61 may be specifically displayed with a figure or a symbol. By adopting this configuration, the monitor 52b can tell whether or not the horizontal discharge auger 6 reaches the grain container 61, so that the operability and workability of grain discharge are improved.

  Moreover, in the structure which provided the transmitter 62 in the container 61 for grains, and provided the receiver 63 in the combine, after pushing the automatic extension switch 64 (FIG. 5), the combine is brought close to the container 61 for grains, It is good also as a structure which the horizontal discharge auger 6 starts a protrusion automatically when it becomes the distance which the horizontal discharge auger 6 reaches. For example, even if the automatic overhanging switch 64 is pressed, if the grain container 61 is far, the horizontal discharge auger 6 does not move, but approaches the grain container 61 so that the horizontal discharge auger 6 reaches the grain container 61. Then, the lateral discharge auger 6 starts to be automatically extended.

  By adopting this configuration, if the automatic overhanging switch 64 is pressed, the horizontal discharge auger 6 is automatically extended when the combine approaches the grain container 61, so that the grain discharge workability is improved. To do.

  Further, in the configuration in which the transmitter 62 is provided in the grain container 61 and the receiver 63 is provided in the combine, the combine is brought close to the grain container 61 so that the lateral discharge auger 6 can reach the grain container 61. Then, it is good also as a structure which the lamp | ramp 52c (FIG. 7) provided in the operation seat 9 lights. In the example shown in FIG. 7, the lamp 52 c is provided as an example of the notification device 52 on the monitor 52 b. However, the lamp 52 c may be provided on the operation unit 53 (FIG. 5) of the horizontal discharge auger 6. It may be provided. As the notification device 52, a buzzer 52a and a speaker may be provided in addition to the lamp 52c. When the lateral discharge auger 6 reaches a distance that reaches the grain container 61, the buzzer 52a (FIG. 5) may sound or may be informed by a speaker. The buzzer 52a and the speaker are not limited to the operation unit 53, and may be provided anywhere. By adopting this configuration, when the distance of the horizontal discharge auger 6 reaches the grain container 61, the lamp 52c of the operation seat 9 is turned on or the buzzer 52a sounds, so that the grain discharge workability is improved. To do. In addition, if a speaker is provided, it is informed by voice, so it is easy to understand in detail and easy to understand, improving the operability of grain discharge. In addition, since the notification is made by voice, the worker is not worried.
