  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

  First, the overall structure of the combine will be described with reference to FIGS. 1 and 2.

  As shown in FIGS. 1 and 2, the combine is provided with a crawler type traveling machine body 1. A cutting part 2 is provided in front of the traveling machine body 1. A driving unit 3 is provided at the front of the traveling machine body 1. An engine 4 is provided below the operation unit 3. Moreover, the grain tank 5 and the threshing apparatus 6 which store a grain are juxtaposed in the left-right direction of the body behind the operation unit 3. The grain tank 5 is provided with a grain discharge auger 7 for discharging the grains in the grain tank 5 to the outside.

  The grain discharge auger 7 includes a vertical auger 8 and a horizontal auger 9.

  The vertical auger 8 conveys the grain in the grain tank 5 upward. And the vertical auger 8 is provided with the vertical screw 10 for grain conveyance. In addition, the vertical auger 8 is configured to be swingable around the vertical axis Y1. The vertical auger 8 is driven to swing around the axis Y1 by the turning motor 11.

  The horizontal auger 9 conveys the grain from the vertical auger 8 in the horizontal direction and discharges it to the outside. And the horizontal auger 9 is equipped with the horizontal screw 12 for grain conveyance. Further, the horizontal auger 9 is connected to the vertical auger 8 so as to be swingable up and down around an axis X1 that is laterally oriented. The horizontal auger 9 is driven to swing up and down around the axis X1 by a hydraulic cylinder 13. Further, the horizontal auger 9 is connected to the vertical auger 8 so as to be able to turn around a vertical axis Y1. That is, when the vertical auger 8 is driven to swing around the axis Y1 by the turning motor 11, the horizontal auger 9 turns around the axis Y1. The horizontal auger 9 is supported by the support base 14 at a predetermined storage position. Further, the horizontal auger 9 includes a proximal end side auger 15, a distal end side auger 16, and an electric drive unit 17.

  The proximal auger 15 is disposed on the proximal end side (vertical auger 8 side) of the horizontal auger 9. The proximal auger 15 includes a proximal-side lateral screw 18 on the proximal side of the lateral screw 12. Further, a folding shaft 19 having an up and down axis Y2 is provided at the end of the proximal auger 15 on the distal auger 16 side.

  The distal auger 16 is disposed on the distal end side of the horizontal auger 9. The distal auger 16 is provided with a distal side lateral screw 20 on the distal side of the lateral screw 12. The distal auger 16 is driven to swing around the folding shaft 19 (axial core Y2) by the electric drive unit 17. That is, the distal end auger 16 swings around the folding shaft 19 (axial core Y2) and is folded with respect to the proximal end auger 15 in a discharge state connected to the proximal end auger 15 in a straight line. It can be switched to a folded state. The distal auger 16 is configured to be parallel to the proximal auger 15 in the folded state at the storage position. That is, the distal end side auger 16 is configured to swing 180 degrees around the folding shaft 19 (axial core Y2).

  The electric drive unit 17 is disposed below the horizontal auger 9. The electric drive unit 17 includes an electric motor 23 that is driven by the control unit 50.

  Next, the control unit 50 will be described with reference to FIG.

  As shown in FIG. 3, the control unit 50 includes a changeover switch 51 as “switching means”, a switching state detection sensor 43 as “switching state detection means”, a start switch 56 as “starting means”, the engine 4, And the electric motor 23 is connected.

  The changeover switch 51 transmits a changeover signal for switching the distal end side auger 16 to a discharged state or a folded state to the control unit 50. For example, the changeover switch 51 is disposed in the operation unit 3. Note that the changeover switch 51 transmits the changeover signal even if the changeover switch 51 is pressed once, even if it is not kept pressed.

  The switching state detection sensor 43 detects the discharge state and the folded state, and sends a detection signal to the control unit 50. Specifically, the switching state detection sensor 43 detects the swing angle of the distal auger 16 around the folding shaft 19 (axial core Y2). For example, the switching state detection sensor 43 is composed of a potentiometer.

  The start switch 56 can be switched between a start position for transmitting a start signal for starting the engine 4, an accessory position for transmitting an accessory signal (power-on signal), and a stop position for transmitting a stop signal for stopping the engine 4. It is configured. For example, the start switch 56 is configured to be able to switch between a start position, an accessory position, and a stop position by inserting a key (key type). Then, the start switch 56 transmits each signal to the control unit 50.

  The control unit 50 receives the switching signal from the changeover switch 51 and drives the electric motor 23 to execute the bending / extending process for switching the distal end side auger 16 to the discharged state or the folded state. Then, the control unit 50 receives the start signal from the start switch 56 and starts the engine 4. Further, the control unit 50 receives a detection signal from the switching state detection sensor 43 (the swing angle of the distal auger 16 around the folding shaft 19 (axial core Y2)), and a detection signal from the switching state detection sensor 43. Based on the above, it is determined whether or not the distal end side auger 16 is in the discharged state, the folded state, or the folding state.

  Next, a control flow of the control unit 50 according to the first embodiment of the present invention will be described with reference to FIG.

  As shown in FIG. 4, the control unit 50 determines whether a start signal or an accessory signal has been received (S1). If the control unit 50 determines that neither the start signal nor the accessory signal is received (S1: No), neither the start of the engine 4 nor the bending / extending process is executed.

  When it is determined that the start signal has been received (S1: start signal), the control unit 50 determines whether or not the distal end auger 16 is in the ejected state or the folded state (S2). And when the control part 50 judges that the front end side auger 16 is a discharge | emission state or a folding state (S2: Yes), the engine 4 is started (S3).

  Further, when the control unit 50 determines that the distal end auger 16 is neither in the ejected state nor the folded state, that is, the distal end side auger 16 is in the middle of folding (S2: No), the engine 4 is started. I won't let you.

  Moreover, when it is judged that the control part 50 received the accessory signal (S1: accessory signal), it is judged whether the front end side auger 16 is a discharge | emission state or a folding state (S4). And when the control part 50 judges that the front end side auger 16 is a discharge | emission state or a folding state (S4: Yes), it does not perform a bending / extension process.

  In addition, when the control unit 50 determines that the distal end auger 16 is neither in the ejected state nor the folded state, that is, the distal end side auger 16 is in the folding state (S4: No), the control unit 50 executes the bending and stretching process. (S5). Thereby, the front end side auger 16 is switched to either the discharged state or the folded state.

  With such a configuration, the engine 4 is not started when the distal end side auger 16 is neither in the discharged state nor in the folded state, that is, when the distal end side auger 16 is in the middle of folding. Therefore, it is possible to prevent the distal end auger 16 from traveling while being folded.

  Then, when the start switch 56 is switched to the accessory position when the distal end side auger 16 is in the middle of folding, that is, when the start switch 56 transmits an accessory signal (power-on signal), the bending process of the control unit 50 is performed. Is executed. As a result, the engine 4 can be started after the front end side auger 16 is switched from the middle folding state to the discharged state or the folded state simply by switching the start switch 56 between the accessory position and the starting position. The engine 4 can be easily started from the state of being folded.

  Next, a control flow of the control unit 50 according to the second embodiment of the present invention will be described with reference to FIG.

  As shown in FIG. 5, the control unit 50 determines whether or not a start signal has been received (S1). Then, when it is determined that the start signal has not been received (S1: No), the control unit 50 does not start the engine 4.

  Moreover, when it is judged that the control part 50 received the starting signal (S1: Yes), it is judged whether the front end side auger 16 is a discharge | emission state or a folding state (S2). And when the control part 50 judges that the front end side auger 16 is a discharge | emission state or a folding state (S2: Yes), the engine 4 is started (S3).

  Further, when the control unit 50 determines that the distal end auger 16 is neither in the ejected state nor the folded state, that is, the distal end side auger 16 is in the middle of folding (S2: No), the engine 4 is started. I won't let you.

  With such a configuration, the engine 4 is not started when the distal end side auger 16 is neither in the discharged state nor in the folded state, that is, when the distal end side auger 16 is in the middle of folding. Therefore, it is possible to prevent the distal end auger 16 from traveling while being folded.

  In the second embodiment, the engine 4 can be started by the start switch 56 when the operator switches the distal end auger 16 in the middle of the folding state to the discharging state or the folding state by the changeover switch 51. .

  Hereinafter, another embodiment according to the present invention will be described.

(1) In said 1st embodiment, when the control part 50 judges that the front end side auger 16 is in the folding middle state (S4: No), it is near from the folding middle state among a discharge state and a folding state. You may comprise so that the front end side auger 16 may be switched to the direction. In this case, the control unit 50 determines, based on the detection signal from the switching state detection sensor 43, which one of the discharging state and the folding state is closer from the folding state.

(2) In the first embodiment, the start switch 56 is configured as a key, but the start switch 56 may be configured as a button. Specifically, it may be configured to include a button for transmitting a start signal, an accessory signal, and a stop signal (three, two, or one button appropriately combined).

(3) In the first embodiment, when the lateral auger 9 is in the predetermined storage position, the lateral auger 9 is not in the predetermined storage position (the horizontal auger 9 is in an arbitrary swiveling position). It is also applicable in some cases. When the horizontal auger 9 is not in the predetermined storage position, the control unit 50 switches the distal auger 16 to the folded state while returning the horizontal auger 9 to the predetermined storage position, or the horizontal auger 9 is changed to the predetermined storage position. After returning to the storage position, the distal auger 16 may be switched to the folded state, or after switching the distal end auger 16 to the folded state, the lateral auger 9 may be returned to the predetermined storage position. . In this case, the control unit 50 serves as “accommodating state detection means” for detecting that the lateral auger 9 is supported by the support base 14 (the lateral auger 9 is located at a predetermined storage position). An accommodation state detection sensor (not shown) is connected.

  INDUSTRIAL APPLICATION This invention can be utilized for a combine provided with the grain discharge auger which discharges the grain in a grain tank outside.
