Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention comprises an auger for swinging and elevating the grain with respect to the machine body, a discharge state detecting means for detecting whether or not the grain is discharged from the auger, and an auger for the auger described above. A control means for controlling the operation of the moving actuator, and a manually operated command means for giving a return command to the control means so that the auger automatically returns to the storage position for the machine body, the control means are provided. The present invention relates to a combine configured to prohibit the operation of the moving actuator even when the return command is given when the discharge state detecting means detects the discharge state.

[0002]

[Prior art]

 If the auger automatically returns to the storage position while the grains stored in the tank are being discharged to the carrier, etc., the grains will be scattered on the ground surface. To prevent this, the auger does not automatically recover even if a worker gives a recovery command by mistake while discharging grains. By the way, heretofore, there has not been provided any means for making the operator clearly recognize that the operation is incorrect when the operator gives a return command by mistake.

[0003]

[Problems to be solved by the device]

 In the above-mentioned conventional technique, there is a possibility that the worker does not notice that the operator has performed an erroneous operation. As a result, there is a risk that the auger may start traveling without being stored in the storage position. An object of the present invention is to eliminate the above-mentioned conventional drawbacks and make the manufacturer clearly recognize that a return command is erroneously given.

[0004]

[Means for Solving the Problems]

 In order to achieve this object, the characteristic configuration of the combine according to the present invention is to provide an alarm means for issuing an alarm when the return command is given while the discharge state detecting means detects the discharge state. That is what is being done.

[0005]

[Action]

 When the operator operates the command means to automatically return the auger to the storage position, the auger automatically returns to the storage position when the discharge state detecting means does not detect the discharge state. On the other hand, when the discharge state detection means detects the discharge state, the movement of the auger is prohibited and the alarm means issues an alarm.

[0006]

[Effect of device]

 When a return command is erroneously given, an alarm is issued, so that the operator can clearly recognize that the return command is erroneously given.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 8 and FIG. 9, in the combine, a mowing section 2 is provided in the front part of a body V having a pair of left and right crawler traveling devices 1, and a control section 3, a mowing section are provided on the rear side of the mowing section 2. A threshing device 4 for threshing the culms cut by the part 2 to sort and collect the grains and a grain tank 5 for storing the grains sorted and collected by the threshing device 4 are mounted. . An auger 6 for discharging the grains stored in the grain tank 5 to the outside of the machine is provided on the rear side of the grain tank 5 so as to be rotatable and movable up and down.

Explaining the turning operation structure of the auger 6, as shown in FIG. 6, the connection case 11 A connected to the base end of the horizontal screw conveyor 11 has a vertical screw conveyor at the upper end of the vertical screw conveyor 10. It is fitted rotatably around a vertical axis Y that coincides with the screw axial center of 10. A gear 14 for turning drive is fixed to the outer surface of the connection case 11A. Then, an electric motor 16 for rotation, which rotationally drives the gear 15 that meshes with the gear 14 for rotation, is fixedly provided on the vertical screw conveyor 10, so that the electric motor 16 is driven in forward and reverse directions. Accordingly, the auger 6 is turned around the vertical axis Y, and the turning is stopped when the electric motor 16 is stopped. In the figure, Ry is a turning position detection sensor utilizing a multi-rotation type potentiometer for detecting the turning position of the auger 6, and is connected to the turning drive gear 14 by the gear 15 driven by the electric motor 16. It is designed to be rotated at the same time. However, as shown in FIG. 7, when the electric motor 16 reaches the left and right limits of the preset turning range based on the detection information of the pair of limit switches L 1 and L 2, it automatically It is supposed to be stopped.

Explaining the lifting / lowering operation structure of the auger 6, as shown in FIG. 6, the base end portion of the horizontal screw conveyor 11 has a horizontal axis core intersecting the vertical axis Y 1 at the upper end of the connection case 11A. It is also pivotally attached around X. An elevating hydraulic cylinder 17 is provided between the base end of the horizontal screw conveyor 11 and the connection case 11A, and as the hydraulic cylinder 17 is extended, the auger 6 is moved up and down. The auger 6 is operated to be lowered as the hydraulic cylinder 17 is contracted. In the figure, L3 is an upper limit switch that is turned on when the auger 6 is at the upper limit position, and 29 is a contact plate that contacts the limit switches L1 and L2.

The control unit 3 is provided with an operation unit 30 including a plurality of manually-operated switches for instructing the drive of the turning electric motor 16 and the lifting hydraulic cylinder 17. The operation section 30 will be described. As shown in FIG. 1, four push-button type manual switches for individually instructing each of left turn, right turn, ascent, and descent while pushing is being performed. S1 to S4 are provided. Further, the position of the auger 6 can be automatically moved to the storage position or the discharge position. In the figure, S5 is an automatic switch for this purpose. By operating this switch S5, the switch is automatically moved to the discharge position when the auger 6 is in the storage position, and to the storage position when the auger 6 is in a position other than the storage position. It can be moved automatically. That is, a manually operated command in which the turning electric motor 16 and the lifting hydraulic cylinder 17 give a moving actuator of the auger 6 and an automatic switch S5 gives a returning command so that the auger 6 automatically returns to the storage position for the machine body V. Corresponds to the means. Further, a discharge switch S8 for turning ON / OFF the discharge of the grain from the auger 6 is provided. When the discharge switch S8 is in the ON state, it is determined that the auger 6 is in the discharge state for discharging the grains. That is, the discharge switch S8 corresponds to the discharge state detecting means. In the figure, 25 is a buzzer as an alarm means, 26 is a lamp for indicating whether or not the auger 6 is at the storage position, S7 is a discharge position setting volume for setting a voltage value Vs described later at the discharge position, and S6 is an auger 6 Is a stop switch for making an emergency stop, 27 is a drive circuit for the electric motor 16, and 28 is a control valve for the cylinder 17.

Next, a control configuration for turning and raising and lowering the auger 6 will be described. As shown in FIG. 1, a control device H using a microcomputer is provided, and each switch of the operation unit 30, the limit switches L1, L2, L3, and the position detection sensor Ry are connected to the control device H. ing. Then, the control device H is configured to operate the electric motor 16 and the hydraulic cylinder 17 based on the preset information and various input information. That is, the control means 100 is configured using the control device H.

When the moving operation of the auger 6 is added, as shown in FIG. 7, the auger 6 is configured to be able to turn and move up and down within a movable range. The turning position of the auger 6 with respect to the machine body V is detected as the voltage value Vx of the turning position detection sensor Ry. The voltage value Vx increases as the auger 6 turns to the right. However, as shown in FIG. 9, the regulation area K is set within the movable range. The restricted area K is an area within the predetermined turning range A near the control section 3 and less than the upper limit height. Further, boundary regions A1 and A2 are set at both ends of the predetermined turning range A. The voltage value Vx of the detection sensor Ry when the auger 6 is located at the boundary between the boundary areas A1 and A2 is preset and stored. When the voltage values are arranged in ascending order, they become VL1, VL2, VR2 and VR1. The voltage value Vx at the storage position is Vh, and the voltage value Vx at the discharge position is Vs. In the regulated area K, basically, turning and raising of the auger 6 are prohibited. However, in the boundary areas A1 and A2, turning in the direction away from the restriction area K is allowed. In other words, A1 is allowed to turn to the right and A2 is allowed to turn to the left.

By the way, when an operator performs an erroneous movement operation, the drive of the electric motor 16 for turning and the hydraulic cylinder 17 for raising and lowering is prohibited, and an alarm is generated by the buzzer 25. First, when the automatic switch S5 is operated to automatically return the auger 6 to the retracted position while the discharge switch S8 is in the ON state, the drive of the electric motor 16 for turning and the hydraulic cylinder 17 for raising and lowering is prohibited, and An alarm is generated by the buzzer 25. In the operation of the manual switches S1 to S4, the turning electric motor 16 and the lifting / lowering are similarly operated when the switch is operated from the boundary of the restriction region K to the inside of the restriction region K and when the switch is operated from the boundary of the movable range to the outside of the movable range. When the drive of the hydraulic cylinder 17 for use is prohibited, an alarm is issued by the buzzer 25.

Next, the operation of the control device H will be described based on the flowcharts shown in FIGS. 2 to 5. First, the input of the operation unit 30 is checked to determine the operation mode. If the manual switches S1 to S4 are turned on, the manual mode is started, and if the automatic switch S5 is turned on, the automatic turning mode or the automatic storage mode is started. When the automatic switch S5 is turned on, if the voltage value Vx of the detection sensor Ry is substantially equal to Vh, the automatic turning mode is activated. When the voltage value Vx is not equal to Vh and the discharge switch S8 is in the OFF state, the automatic storage mode is activated. However, if the discharge switch S8 is ON, the buzzer 25 issues an alarm without activating the automatic storage mode. The operation in the manual mode will be described. When the left turn switch S1 is ON, the left turn is output until the limit switch L1 is turned ON. However, when the limit switch L1 is ON, the drive of the turning electric motor 16 is prohibited, and an alarm is issued by the buzzer 25. When the voltage value Vx is between VL2 and VR1, the counterclockwise output is output only when the upper limit switch L3 is ON. When the upper limit switch L3 is not ON, the drive of the turning electric motor 16 is prohibited and the warning by the buzzer 25 is generated. When the right turn switch S2 is ON, the right turn is output until the limit switch L2 is turned ON. However, when the limit switch L2 is ON, the drive of the turning electric motor 16 is prohibited and the buzzer 25 issues an alarm. When the voltage value Vx is between VL1 and VR2, the right turn output is made only when the upper limit switch L3 is ON. When the upper limit switch L3 is not ON, the drive of the turning electric motor 16 is prohibited and the warning by the buzzer 25 is generated. When the rising switch S3 is ON, the rising output is output until the upper limit switch L3 is turned ON. When the down switch S4 is ON, the down output is made. However, when the voltage value Vx is between VL1 and VR1, the lifting hydraulic cylinder 17 is prohibited from being driven and the buzzer 25 issues an alarm. In the automatic turning mode, the ascending output is output until the upper limit switch L3 is turned on, and then the turning output is performed until the discharge position is reached. In the automatic storage mode, the output is raised until the upper limit switch L3 is turned on once, and then the output is turned until the storage position is reached. When it reaches the storage position, it is output downward for a predetermined time. During this predetermined time, it is checked whether or not the voltage value Vx is substantially equal to Vh, and if they are not equal, the swing output is made to be equal.
