Abstract

PURPOSE:To monitor a working cost as needed by recording working state data, and transferring it on a data storage cord. CONSTITUTION:When rice-planting work is started, a signal from each detector is inputted to a central processing unit 39, and when a rice-planting device B is inclined, an output signal is sent to a control operating device, and inclination is corrected by operating an electric cylinder 27. Also, while the rice- planting work is performed, the number of seedlings is stored, or the workload is stored in travel distance, or the quantity used of fuel is stored from time to time. Furthermore, the depth of a paddy field is detected, and also, the condition of a field is stored. In such a way, it is possible to record all data by connecting an agricultural machinery to the central processing unit 41 of a workload monitor system 40 with a communication line 42 at the time of completing the planting work and setting the card 44 on the central processing unit.

That is, a seedling platform 18 that reciprocates horizontally in the left-right direction is provided at the top of the planting transmission case 17, and a planting tool 19 is provided at the rear end side of the seedling platform 18 for separating and transplanting seedlings one by one from the seedling platform 18. established.

A float 20 for leveling the transplant soil surface is attached to the lower part.

The lifting bag RC has the bases of the upper link 21 and the lower link 22 pivotally connected to the support column 16, the rear portions being pivotally connected by a vertical link 23, and a hydraulic bag between the rear mission case 3 and the upper link 21. A control valve 25 of this hydraulic device 24 is provided between the flow 20 and the planting transmission case 17, and the valve 25 is switched by the vertical movement of the front part of the float 20 to raise and lower the link. It is configured to do so.

Then, the left and right center front parts of the planting transmission case 17 of the rice transplanting device B are attached to the lower end side of the vertical link 23 so as to be movable, and the vertical link 23 and the metal fitting 26 protruding from the front part of the case 17 are connected to each other. An electric cylinder 27 formed by a stepping motor is interposed between them, and the electric cylinder 27 is controlled by an inclination detector 29 of the rice transplanting device B using a pendulum 28 attached to this metal fitting 26 and capable of rotating left and right.

To explain the control block circuit diagram of FIG. 5, numeral 38 is a work machine control system section, and the central processing unit 39 (CPU) receives signals from the respective detectors 29, 30, 32, 34, and 35. It is configured to be able to store these signals as they are, or to process and store these signals, or to send out appropriate command signals. That is, when the signal from the detector 29 continues for a certain period of time as a tilt signal greater than the reference value, the stepping motor is rotated forward and backward, the electric cylinder 27 is moved in and out, and the rice transplanting apparatus B is controlled to rotate toward the horizontal state. The signals from the detector 30 are added together to store how many seedlings have been used. Further, from the signal from the detector 32, the traveling distance is calculated from the rotation speed of the drive shaft and stored. Furthermore, the amount of fuel consumed is stored in accordance with the signal from the detector 34, and the depth of the paddy field being worked in is stored in accordance with the signal from the detector 35. Note that since slipping occurs in the travel distance, data on the depth of the detector 35 is used as a factor to reduce errors.

To explain the operation of the upper part in detail, the one-ride type rice transplanter is driven into a paddy field and the start switch of the control mechanism is turned on before starting one operation. Immediately, this model (riding-type 5-row rice transplanter) is registered, and the hourly usage fee for this rice transplanter is simultaneously registered as reference data. When rice transplanting work starts, signals from each detector are input to the central processing unit 39, and if the rice transplanter B is tilted, an output signal is sent to the control actuator and the electric cylinder 2
7 operates to correct the tilt. In addition, the number of seedlings used during rice planting work is stored, the amount of work is stored in the distance traveled, and the amount of fuel used is stored moment by moment. Furthermore, the depth of the paddy field is detected and even field conditions are stored.

Therefore, at the end of the planting work, it is connected to the central processing unit 41 of the work amount monitoring system 40 through the communication line 42,
