Abstract

PURPOSE:To prevent trouble, e.g. an obstruction of a preparatory work due to unexpected rolling motions or loss of a rolling motion function during a ground work. CONSTITUTION:A working unit is connected to a running machine body so as to be driven and freely rolled round a longitudinal shaft by a motor 10b and the working unit is equipped with a level sensor 16 for detecting the tilt angle from the horizontal posture. The working unit is designed so as to be kept in the horizontal posture by driving the motor 10b based on a detected result by the level sensor 16. This rolling-control mechanism is also equipped with a car body stop state detection switch (SW1) for detecting the stop state of the running machine body and with a clutch actuation detection switch (SW3) for detecting the connected state of an operation clutch. If each of the detection switches (SW1) and (SW3) is in a detection state, the motor 10b is automatically controlled so as to be stopped at a horizontal and neutral position.

2. Description of the Related Art Conventionally, in a rolling control mechanism of a paddy working machine, for example, a riding type rice transplanter, conventionally, a seedling planting mechanism of a seedling planting apparatus as an example of a ground working apparatus is used to adjust a seedling taking amount and fertilizer for side strips. When adjusting the fertilizer application rate of the device before planting work, the traveling machine is stopped and the seedling planting device is slightly floated above the ground, and the seedling planting device is operated, but there is no hunting. Since the actuator is connected via the elastic body for buffering to perform smooth rolling operation, when performing the preparatory work as described above, when the seedling planting device is touched by the hand, the seedling planting device will move to the left and right. It vibrates. As a result, the seedling planting device may deviate from the horizontal posture with respect to the ground, the rolling control may be activated, and the seedling planting device may generate unexpectedly large vibrations, which may prevent the preparation work from smoothly. When performing such a work, the operation stopping operation tool for exclusive use for stopping the rolling control operation is cut and operated.

However, in the above-mentioned conventional structure, when performing the above-mentioned preparation work, there is a possibility that the operator forgets to turn off the operation stop operation tool and performs the work. In such a case, the planting equipment vibrates and it becomes difficult to perform the work. Even when the operation stopping tool is turned off, the seedling planting work may be started by forgetting to enter the operation stopping tool after the preparation work is completed, and the rolling control does not operate. There was a problem such as ground work being performed and the ground work depth not being constant, and there was room for improvement. The present invention aims to eliminate the above-mentioned problems.

The seedling planting device 4 is constructed so that it is always maintained in an absolute horizontal posture during planting work. In other words, the wheels of the traveling body run on a hard cultivator below the soft mud layer, and the seedling planting device 4 plants seedlings in the mud layer, so that the posture against mud is always kept constant. Although necessary, the surface of the mud is considered to be almost horizontal, and the seedling planting device 4 is maintained and controlled in a horizontal posture. More specifically, as shown in FIG. 1, the rolling operation electric motor 10b is configured to be controlled and driven by a control device 14 equipped with a microcomputer, and the control device 14 is controlled from an absolute horizontal posture of the seedling planting device 4. The detection result of the weight type horizontal sensor 16 for detecting the inclination angle of the electric field is input, and the electric motor 10b is drive-controlled based on the detection result so as to maintain the ground posture of the seedling planting device 4 in a predetermined control target state. The rolling control means A is provided in the form of a control program. Further, a neutral position detection switch SW1 [an example of a vehicle body stop detection means] for detecting that the speed change lever 25 is operated to a neutral position is provided near the speed change lever 25, and a clutch is engaged near the main clutch pedal 24. The main clutch detection switch SW2 for detecting the state of being in a state and the planted clutch detection switch SW3 for detecting that the planted clutch 21 is engaged and operated (an example of a clutch operation detection means) are provided, and each detection is performed. The outputs of the switches SW1, SW2, SW3 are given to the control device 14, and when the detection switches SW1, SW2, SW3 are in the detection state, the control device 14 controls the rolling lock operating means B for stopping the rolling operation by the electric motor 10b. It is provided in the control program format. That is, the control device 14 executes control as follows.

As shown in FIG. 2, the detection value of the horizontal sensor 16 is read [step 1], and each detection switch SW is read.
1, SW2, SW3 are judged, and if all the detection switches are in the detected state, that is, the shift lever 25 is in the neutral position, the main clutch 22 is engaged, and
And, when the planting clutch 21 is engaged and operated,
If the seedling planting device 4 deviates from the horizontal posture based on the detection value of the horizontal sensor 16, the electric motor 10d is operated to return to the horizontal neutral position, and then the operation of the electric motor 10b is stopped [steps 2 to 7]. ]. If any of the detection switches SW1, SW2, SW3 is in the non-detection state, the electric motor 10b is operated and controlled so that the detection value of the horizontal sensor 16 falls within the horizontal target level, and the seedling planting device 4 is operated. Rolling control for maintaining a substantially horizontal posture is executed [step 8]. Therefore, when performing the preparatory work such as the adjustment of the fertilizer application amount of the fertilizer application device 8 and the adjustment of the seedling removal amount by the planting mechanism 6 prior to the seedling planting work, the planting mechanism 6 is driven with the traveling machine stopped. While doing the work, in that case, the above steps 5 to 7
The operation of the electric motor 10b is stopped in the neutral state by the control of 1.
It does not hinder the work due to the unexpected operation of the. The step 8 constitutes the rolling control means A, and the steps 5 to 7 constitute the rolling lock operation means B.
