Next, the operation and the like of the farm work system S will be described.

As shown in FIG. 6, the control unit 71 of the agricultural work machine 1 is based on the operation of the drive unit display (open button 81, close button 82) 91 in the operation screen displayed on the touch panel monitor 9 of the tractor 2. Then, the cylinder operation signal (operation command signal of the drive unit) from the tractor control unit 8 is received (step 1).

Then, the control unit 71 determines whether or not the PTO 7 is stopped based on the information from the tractor control unit 8, that is, the PTO information regarding the state of the PTO 7 (for example, the rotation speed signal of the PTO, the PTO stop completion signal, etc.). (Step 2).

When the control unit 71 determines that the PTO 7 is not stopped, the control unit 71 transmits a PTO stop signal, which is a power take-out unit stop signal for stopping the PTO 7, to the tractor control unit 8 (step 3). When receiving the PTO stop signal from the control unit 71 of the agricultural work machine 1, the tractor control unit 8 of the tractor 2 automatically stops the rotating PTO 7.

When the control unit 71 determines that the PTO 7 is stopped, the control unit 71 operates the working unit rotating cylinder 15 based on the cylinder operation signal (step 4). As a result, the extension work part 12 rotates with respect to the central work part 11 in a desired state with the PTO 7, the power transmission part 34, and the rotation work part 16 stopped rotating.

Specifically, for example, when the close button 82 is operated, the left and right extension working parts 12 rotate in the closing direction with respect to the central working part 11 to be in the folding non-working state. When starting the scratching work, the operator performs an operation operation of the PTO 7 (such as an ON operation of the PTO operation switch). A button that functions as a PTO operation switch may be displayed on the touch panel monitor 9.

Then, according to such an agricultural work system S, only when the PTO 7, the power transmission unit 34, and the rotary work unit 16 are completely stopped, the drive unit (two cylinders 15, 15) is generated based on the drive unit operation signal. Since at least one of the above) operates, it is possible to avoid the problem that the parts such as the clutches 33 and 53 are damaged even if the PTO 7 is forgotten to be stopped, thus improving the durability. be able to.

In the first embodiment, the tractor control unit 8 is electrically connected to a touch panel monitor (an operation unit that also serves as a display unit) 9 by wire or wirelessly, and the control unit 71 is a touch panel type. The configuration for receiving the drive unit operation signal (cylinder operation signal) based on the operation of the drive unit display (buttons 81, 82) of the monitor 9 and determining whether or not the PTO is stopped has been described, but the configuration is not limited to this. Instead, for example, the configuration shown in FIG. 7 may be used.

In the control unit 71 shown in FIG. 7, a touch panel remote controller (an operation unit also serving as a display unit) 92 for displaying the same operation screen as the touch panel monitor 9 (for example, the screen shown in FIG. 5) is wired or connected. It is electrically connected wirelessly, and its control unit 71 receives a drive unit operation signal (cylinder operation signal) based on the operation of the drive unit display (buttons 81, 82) of the touch panel remote control 92 and receives the PTO. It is configured to judge the presence or absence of suspension. Like the touch panel monitor 9, the touch panel remote controller 92 is arranged near the driver's seat of the tractor 2 and is touch-operated by an operator who is in the driver's seat. Note that, for example, both the touch panel type monitor 9 and the remote controller 92 may be used.

Further, for example, although not shown, the agricultural work machine 1 may be configured to include a remote controller (operation unit) having no display unit instead of the touch panel remote controller 92, and the tractor 2 may be used instead of the touch panel monitor 9. Alternatively, a configuration including a monitor (display unit) having no operation unit may be used. Furthermore, a mobile terminal device (smartphone, tablet, etc.) such as a mobile phone may be used as the display unit or the operation unit.

Furthermore, in the first embodiment, the control unit 71 determines whether or not the PTO is stopped only when the open button 81 or the close button 82 of the plurality of buttons 81 to 90 is operated, and other than that, Although the configuration has been described in which whether or not the PTO is stopped is not determined if the button is operated, the present invention is not limited to this configuration. For example, when any of the plurality of buttons 81 to 90 is operated, Alternatively, the control unit 71 may determine whether or not the PTO is stopped.

Next, the farm work system of the second embodiment of the present invention will be described with reference to FIG.

The farm work machine 1 of the farm work system S shown in FIG. 8 is a ridge coater (offset work machine) that is used by being connected to the tractor 2 and that is capable of performing a reverse work (return work is possible). In other words, this agricultural work machine 1 is connected to the three-point link 10 at the rear of the tractor 2 and moves from the PTO 7 of the tractor 2 while moving (moving forward when moving forward, moving backward when moving backward) by traveling of the tractor 2. Agricultural work (row coating work) is performed based on the power (rotation power) of.

This agricultural work machine 1 includes a machine frame 101 detachably connected to the three-point link 10 of the tractor 2, a movable machine frame 103 connected to the machine frame 101 via a connecting means 102, and the movable machine frame 103. And a rotating working unit (ridge coating unit) 104 that is in a forward working state, a retracted non-working state, and a backward working state.

The rotating working unit 104 is rotated by receiving power from a power transmission unit 106 that transmits power from the PTO 7 of the tractor 2. For example, the rotating working unit 104 is a bank 108 that raises soil while rotating in a predetermined direction, and rotates in a predetermined direction. On the other hand, it has a ridge forming body 109 which forms a ridge by compacting the embankment by the embankment body 108. The embankment body 108 has a plurality of tillage claws 108a for plowing and raising soil. The ridge forming member 109 has a frustoconical ridge side surface forming portion 109a and a cylindrical ridge upper surface forming portion 109b.

The power transmission unit 106 has, for example, a joint 27, an input shaft 26, an intermediate joint 100, a gear, an intermediate input shaft, a fillet transmission shaft, a ridge forming transmission shaft, and the like. The power transmission unit 106 and the rotating work unit 104 constitute an interlocking unit 110 that rotates in conjunction with the PTO 7 of the tractor 2.

Further, the agricultural work machine 1 includes the first cylinder 111, which is a drive unit for selectively switching the rotating working unit 104 between the forward working state and the retracted non-working state, and the rotating working unit 104 in the retracted non-working state and the backward working state. And a second cylinder 112 which is a drive unit for selectively switching to. Each of the two cylinders 111 and 112 is, for example, an electric hydraulic cylinder.

Further, the agricultural work machine 1 includes a control unit (agricultural work machine control unit) 113 that controls the cylinders 111 and 112 that are actuators. Similar to the first embodiment described above, the tractor control unit 8 is electrically connected to the control unit 113 by wire (or wireless), and these control units 8 and 113 can communicate with each other. There is. That is, for example, the wiring 72 from the tractor control unit 8 and the wiring 73 from the control unit 113 are connected via a connector 74 of the AG-PORT standard. Therefore, an operator who is in the driver's seat of the tractor 2 can operate the farm work machine (ridge coating machine) 1 remotely by operating the operation screen displayed on the touch panel monitor 9 of the tractor 2. ..

The screen for the ridge coating machine displayed on the touch panel monitor 9 has at least a forward button, a retract button, and a backward button, and these three buttons operate the cylinders (drive units) 111 and 112. A display for a drive unit that is operated at that time is configured.

Also in the farm work system S according to the second embodiment, as in the first embodiment described above, as shown in FIG. 6, the control unit 113 of the farm work machine 1 controls the touch panel monitor 9 of the tractor 2. The cylinder operation signal is received from the tractor control unit 8 based on the operation of the drive unit display in the operation screen displayed on the screen (step 1).

Then, the control unit 113 determines whether or not the PTO 7 is stopped based on the information from the tractor control unit 8, that is, the PTO information regarding the state of the PTO 7 (step 2).

When the control unit 113 determines that the PTO 7 is not stopped, the control unit 113 transmits a PTO stop signal for stopping the PTO 7 to the tractor control unit 8 (step 3). When receiving the PTO stop signal from the control unit 113 of the agricultural work machine 1, the tractor control unit 8 of the tractor 2 automatically stops the rotating PTO 7.

Further, when the control unit 113 determines that the PTO 7 is stopped, the control unit 113 operates the cylinders 111 and 112 based on the cylinder operation signal (step 4). As a result, with the PTO 7, the power transmission unit 106, and the rotary working unit 104 stopped rotating, the rotary working unit 104 moves with respect to the machine casing 101 to a desired state.

Also in the second embodiment, similarly to the first embodiment, the drive is performed based on the drive unit operation signal only when the PTO 7, the power transmission unit 106, and the rotary working unit 104 are completely stopped. Since the part (at least one of the two cylinders 111 and 112) operates, even if the operator forgets to stop the PTO 7, it is possible to avoid the problem that parts such as the intermediate joint 100 are damaged. Therefore, the durability can be improved.

Note that, also in the second embodiment, as in the configuration shown in FIG. 7, a touch panel type remote controller that is an operation unit that also serves as a display unit may be used. Further, in addition to a configuration including both a touch panel type monitor and a remote controller, a configuration in which the agricultural working machine 1 includes a remote controller (operation unit) without a display unit, and a configuration in which the tractor 2 does not include an operation unit (display unit) are provided. A configuration provided may be used.

On the other hand, in the first and second embodiments, is the control unit (agricultural work machine side control unit) 71, 113 of the agricultural work machine 1 based on the information from the tractor control unit 8 whether the PTO is stopped? Although the configuration for determining whether the PTO has been described has been described, for example, a configuration for determining whether or not the PTO is stopped may be used based on information from a detection unit such as a sensor of an optical system.

This detection unit is for detecting the state of the interlocking means 17, 110 interlocked with the rotation of the PTO (power take-out unit), and is, for example, a rotation detection sensor for detecting the rotation of the input shaft, the gear and the like. For example, in the agricultural work machine (scraper) 1 shown in FIG. 1, the detection unit is provided in the shaft support portion 25 of the central machine body 21, and, for example, in the agricultural work machine (ridge coating machine) 1 shown in FIG. Is provided in the shaft support portion 99 of the machine frame 101.

Further, in the first and second embodiments, the tractor control unit (traveling vehicle side control unit) 8 of the tractor 2 stops the PTO when receiving the PTO stop signal from the control units 71 and 113 (automatically. The configuration has been described.
