Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an automatic control display method for mobile agricultural machinery such as a combine harvester.

<Prior art> Conventionally, for example, in a combine harvester, an automatic direction sensor is provided protruding from the side of a divider provided in front of the pre-processing section, and the left and right side clutches are controlled by detecting the state of contact of the sensor with rice plants, etc. An automatic direction control is adopted, and the conditions for operating this automatic direction control are that the automatic direction control switch that selects between manual and automatic is turned on, the reaping clutch is engaged, and the vehicle is running. The vehicle is moving forward, the side clutch is being operated manually, and one of the left and right sensors has been activated at least once.

In order to operate the automatic direction control, all of these operating conditions must be satisfied, and if even one of them is not satisfied, the automatic direction control is not actually performed.

<Problems to be Solved by the Invention> However, in the conventional control system as described above, even if the operator turns on the automatic changeover switch to use automatic direction control, one of the automatic operating conditions described above is not met. However, if this is not established, or if these detectors are disconnected or have poor contact, or if the control device itself is malfunctioning, actual directional control will not be performed and the grain culm will move against the operator's will. There were drawbacks such as leaving behind mowing, and the machine continuing to move forward and colliding with obstacles, causing damage to the machine.

In addition, in the case of automatic direction control, whether to start mowing from the edge of the field (standard) or from the center (intermediate splitting).
Based on the difference in reaping methods, it is required to change the automatic direction control contents to perform appropriate direction control, but the switching of the changeover switch to select between standard and intermediate division is dependent on the operator. When this is switched, conventional control systems do not have a special means to identify and display this.
When control actually started, there was a drawback that directional control was not performed properly due to incorrect selection.

<Means for Solving the Problems> The automatic control display method of the present invention for solving the above problems includes a direction automatic control device that operates the left and right side clutches based on the detection results of the direction sensors 13 and 14. The automatic changeover switch 10, each detector that sets the operating conditions for automatic control, and the standard
Each signal of the changeover switch 9 that changes the control content to intermediate control is input, and as the automatic changeover switch 10 and each detector that sets the operating condition detect "on", the standard selected by the changeover switch 9,
Alternatively, while automatically controlling each direction of the intermediate division,
The display panel 1 has an indicator lamp 19 for automatic direction control.
When all of the operating conditions described above are met, the display lamp 19 is configured by the control device to display whether the control content of standard or intermediate control is being executed in different modes, such as a continuous lighting state and a flashing state. In other cases, the display lamp 19 is turned off.

<Operation> When performing automatic reaping work, the automatic direction changeover switch 10 is turned on. In this case, even if the operator turns on the automatic changeover switch 10, the automatic direction control display lamp 19 remains off, and when the actual mowing operation begins, each detector that sets the operating conditions is not set. Only when this is satisfied, the indicator lamp 19 lights up to indicate that the automatic direction control is actually in operation.

Further, in this case, the lighting of the indicator lamp 19 is displayed in different modes, such as a continuous lighting state and a blinking state, based on the standard or intermediate control selected by the changeover switch 9.

Therefore, the operator confirms with the display lamp 19 that the automatic direction control is operating correctly, and concentrates on monitoring the reaping and threshing work status, or leaves the operator's seat and performs other tasks such as replacing the paddy bag. be able to. In addition, the operator can confirm that the current reaping method is standard and that the lamp is continuously lit depending on whether the indicator lamp 19 is lit continuously or blinks.
Alternatively, it is possible to immediately determine that the lamp is blinking in the middle, and to perform error-free and appropriate control. Incidentally, if there is an error in the control, the changeover switch 9 is operated to change the control contents appropriately.

Furthermore, when the automatic changeover switch 10 is turned on to start reaping work, if the indicator lamp 19 continues to go out, it means that the automatic direction control is not being performed, and in that case, the operator must stop the reaping work. For example, if the indicator lamp 19 continues to go out, the operator should interrupt the operation and reconfirm whether the reaping clutch is engaged. Since it can be predicted that the reaping operation will occur, it is possible to abandon the reaping work using automatic control and safely continue the work manually, or to repair the malfunctioning part and resume work efficiently under automatic control. can.

<Example> To explain in detail the embodiment of the present invention illustrated below, FIGS. 1 and 2 show operation display panels for combine harvesters. Panel 1 shows the state of the battery and cooling water of the machine and the work target in the upper row. It is equipped with a condition display section 2 that displays the type of material etc. with a lamp, an automatic control display section 3, a side clutch manual operation lever 4, a main switch 5, etc. In the lower row, there is a cutting height position setting switch 6, and a manual shallow handling switch. Deep handling switch 7, automatic handling depth switch 8, standard/intermediate cutting switch 9 for setting whether to start mowing from the edge of the field (standard) or from the center (intermediate cutting) (note: this Depending on the settings, it is determined whether the left and right sensors that automatically control the running direction are activated on the left or right side), automatic direction changeover switch 10, alarm stop switch 11, left and right direction indicators 12, etc. are installed side by side. .

At the left and right ends of the upper part of the automatic control display section 3 are lamps L and R that are turned on when the left and right direction indicators 12 are operated.
is provided, and between them there are installed an automatic handling depth indicator lamp 15, a paddy discharge indicator lamp 16, an air cleaner operation indicator lamp 17, etc., and in the center of the lower part there is an overall indicator lamp 18 for the combine harvester. On the left side thereof, an indicator lamp 19 for automatic direction control and an indicator lamp 20 for automatic cutting height control are provided. Further, a notter operation indicator lamp 21 is provided on the right side of the overall indicator lamp 18.

FIG. 3 shows a plan view of automatic directional sensors 13 and 14 protruding inside the left and right dividers 22 and 23, and FIG. A conveyor 25 to be conveyed is shown,
The conveyor 25 is swung up and down about a fulcrum 26 to adjust the gripping position of the grain culm 24 when it is lifted up, thereby adjusting the depth at which the grain culm is fed to the threshing section. 27a is a main sensor that detects that the grain culm 24 is being lifted and conveyed, and 27b and 27c are ear tip sensors that detect the position of the ear tip.

Figures 5 and 6 are flowcharts of the automatic direction control of the combine harvester and the automatic control of the handling depth of grain culms. In the case of automatic direction control, first turn on the main switch 5 and the automatic direction changeover switch 10 to perform the reaping operation. to go into. In that case, either the left or right sensor 13 14 is activated, actual automatic direction control becomes possible, and in that case, the control is selected depending on the state of the intermediate division or standard changeover switch 9, and the control is either standard control or intermediate division. Control is executed. In addition, when these operating conditions are satisfied, the automatic direction control indicator lamp 19 indicates that the direction control is actually in operation, and the indicator lamp 19 remains lit continuously when standard control is performed. Also, when intermediate control is executed, it is displayed in a blinking state.

If any of the above conditions is unsatisfied, the pilot lamp 19 for directional control will not be lit or will be turned off.

Also, when performing automatic handling depth control, the automatic handling depth switch 8 must be turned on, the reaping clutch and petal clutch are turned on, and the main transmission is in forward movement.
When the conditions such as the main sensor 27a being activated are met, the pilot lamp 15 for automatic handling depth is lit, and if one or more of the conditions are missing, the pilot lamp 15 is not lit or is turned off. Ru.

<Effects of the Invention> Since the present invention is configured as described above, when reaping work is performed using automatic direction control, even if the operator turns on the automatic changeover switch 10,
The indicator lamp 19 for the automatic direction control remains off, and the indicator lamp 19 is turned on only when the reaping operation actually starts and all the detectors for setting operating conditions satisfy their operating conditions. Therefore,
The operator can confirm through the display lamp 19 that the automatic direction control is operating correctly, and concentrate on monitoring the reaping and threshing work status, or leave the operator's seat and perform other tasks such as replacing the paddy bag. can.

In addition, the indicator lamp 19 lights up in different modes, such as continuous lighting and flashing, based on the standard or intermediate control selected by the changeover switch 9, so the operator can determine whether the current reaping method is the standard and the lamp is lighting continuously. It is possible to immediately detect that the lamp is blinking or that the lamp is blinking in the middle, and to perform error-free and appropriate control. Moreover, during reaping work, the indicator lamp 19 lights up in a blinking state during the infrequent intermediate control, so if the indicator lamp 19 blinks when the control is switched to standard control afterwards, the operator may have made a mistake. can be easily discovered, and work defects during that time can be minimized.

Furthermore, if the indicator lamp 19 continues to go out, it can be seen that the automatic direction control is not being performed against the operator's will, and in this case the operator should interrupt the reaping operation and, for example, set the reaping clutch in place. If the indicator lamp 19 continues to go out, it can be determined that the cause is a disconnection in the detector, a poor connection, or a failure in the control device itself, so the automatic control It is possible to choose whether to abandon the reaping work and continue the work manually, or to repair the malfunctioning part and resume work efficiently under automatic direction control.
