Further, as shown in the rear view in FIG. 6, the vertical frame 25 of the frame connector 24 is pivotally connected to the lower part of the vertical member 2 of one of the mounting frames 3 with pins 26,
Hooks 27a and 27b are provided on the horizontal frame 27 fixed to the vertical frame 25, and when the front loader 29 is removed, the horizontal frames 27, 27 are removed from above the vertical members 2, 2 as shown in the figure. After holding the front loader 29 apart as described above, the frame connector 24
is rotated clockwise in the figure to engage the hooks 27a, 27b of the horizontal frame 27 with the locking pins 30, 30 on the upper part of the vertical members 2, 2, respectively, and then lock the hook 28a of the lock lever 28. When engaged with the locking pin 30, the upper parts of the left and right vertical members 2, 2 are connected by the frame connector 24, forming a framework shape.

Also, to remove the front loader 29, you can roughly follow the installation procedure described above in reverse.
Fix the stands 13, 13 in an upright position to the mounting frames 3, 3, and then turn the control valve operating lever 3.
2 to move the lift pistons 20a, 20a backward, the lift arms 10, 10 will be lowered, but since the bucket 9 is already in contact with the ground, the rear of the front loader 29 will be moved backwards by the tractor 1.
4, and as a result,
The mounting frames 3, 3 and the mounting feet 6, 6 move upward, and the bottoms of the guide rails 7, 7 (near where the rail parts 7a, 7b join) contact the guide pins 18a, 18a, and the pins 21, 21 Since the pin holes 6c, 6c of the mounting feet 6, 6 and the pin holes 18b, 18b of the guide pins 18a, 18a are free, the pins 21, 21 can be easily connected to the mounting feet 6, 6 and the guide pin 1.
It can be extracted from 8a and 18a. Then, the horizontal frame 27 of the frame connector 24 is lifted to open the upper part of the vertical members 2, 2, and then the piston 20
As shown in FIG. 2, when the left and right mounting frames 3, 3 are tilted forward, the locking pins 5, 5 are removed from the locking holes 17b, 17b, and the guide pins 18a, 20a are projected. 18a is the rail part 7b,
It will move upward along line 7b and come off. Therefore, if the hydraulic hoses to the lift cylinders 20, 20 and the dump cylinders 8, 8 are disconnected from the joints near the control valve 31 and the tractor 14 is moved backward, they will be disconnected from the front loader 29.

Then, a detector S 1 such as a micro switch is attached to at least one of the mounting legs 6, 6 of the left and right mounting frames 3, 3 near the pin hole 6c, and the actuator S 1 c is inserted into the rail portions 7a, 7b. The guide pin 18a of the mounting frame 3 in the installed state can be seen between
actuator S 1 c is pushed by the
The detector S 1 is positioned so that the contact S 1 b is opened and the normally closed contact S 1 b is closed when the guide pin 18a is removed from the attached state. or,
As shown in FIG. 6, a detector S2 such as a micro switch is attached to the vertical member 2 near the rotating base of the vertical frame 25, and when the horizontal frame 27 is in the open state as shown in the same figure, the vertical Since the frame 25 is separated from its actuator S 2c , the normally open contact S 2a is open, but the horizontal frame 27 is bridged between the vertical members 2, 2 and the hooks 27a, 27b are connected to the locking pins 30, 3.
0, the detector S2 is positioned so that the actuator S2c is pushed by the rotating base of the vertical member 2 to close its normally open contact S2a , as shown in FIG. Thus, the power source E is connected to an alarm device A such as a buzzer or an indicator light via a normally closed contact S 1b and a normally open contact S 2a .
Therefore, when the mounting frames 3, 3 are in the attached state, the normally closed contact S1b of the detector S1 is open, so the alarm device A will not operate, but when the horizontal frame 27 of the frame connector 24 is closed. When you start removing the mounting frames 3 and 3, the normally closed contact of the detector S1
Since S 1b will be closed, alarm device A will be activated. Further, reference numeral 33 is a muffler.

[Effects of the Invention] Since the present invention is configured as detailed in the above embodiment, when the front loader is started to be removed while the horizontal frame of the frame connector is closed, the detector is activated and the alarm is activated. However, this will alert you that the transverse frame remains closed. Therefore, this alarm device eliminates the risk of forgetting to open the frame connector, and eliminates the possibility of damaging the muffler by removing the front loader with the frame connector closed.
