 Next, an embodiment of a work vehicle inclinometer according to the present invention will be described with reference to the drawings. Reference numeral 1 denotes a traveling machine body (work vehicle) equipped with a crawler traveling device 2, an engine 3 is mounted on a rear portion of the machine body 1, and a driving operation section 5 framed by a safety frame 4 on a front portion of the machine body 1. Are arranged. A mower 10 is detachably attached to the front of the machine body 1 via a lower link 6, a lift link 8 including a top link 7 and a hydraulic cylinder 9, and the power is supplied from the traveling machine body 1 side to the PTO shaft 11 and freely. It is configured to be transmitted to the mower 10 via the joint shaft 12. It should be noted that the traveling machine body 1 is not exclusively for the mower 10 and various work machines such as a snow blower and a transport machine can be connected depending on the work mode. The operation panel 5 is provided with an operation panel 13 at the front and a driver's seat 14 at the rear. A clutch pedal 14a is provided on one lower side of the operation panel 13, a brake pedal 15 is provided on the other side, and various levers 16, 17, and 18 are arranged around the driver's seat 14 respectively. An operator's M entry / exit passage L is located on the step 19 between the operation panels 13. Reference numerals 20 and 21 denote steering clutch levers (steering levers) for changing the traveling direction of the traveling machine body 1. The steering clutch levers 20 and 21 are located near the center between the operation panel 13 and the driver's seat 14 in a state of protruding above the step 19. A pair of left and right sides are arranged side by side. The steering lever 20 is a kind of horizontal type in which the grips 20a and 21a are bent horizontally, but the grips 20a and 21a are formed into an inverted C shape in plan view with respect to the traveling direction of the aircraft. Is configured.

Reference numeral 22 denotes a work vehicle inclinometer according to the present invention. The inclinometer 22 includes a display panel 23 and a pointer 24. The pointer 24 is rotatably attached to the display board 23 through the pivot pin 25 along the board surface, and is always oriented in the vertical direction by its own weight. Further, on the surface of the display board 23, a scale 26 showing the inclination angle of the machine body is displayed along with the turning locus of the pointer 24 up to 50 degrees in a left-right symmetric manner with 0 degrees as the center. The rotation area of the pointer 24 is divided into a safety area a, a caution area b, and a danger area c corresponding to the scale 26 of the inclination angle. The safety area a is blue and the caution area b is yellow. The dangerous area c is displayed in red. In this embodiment, the board surface on the sharp tip side of the pointer 24 is colored in a belt shape, and the range of 0 degree to about 20 degrees is set as the safety zone a, and that portion is blue and about 20 degrees to about 30 degrees. The caution range b is set within the range of degrees and the part is colored yellow, and the range c of about 20 to 50 degrees is set as the danger range c and the part is colored red. Since the safe area a, the caution area b, and the dangerous area c are different depending on the width of the machine body, the position of the center of gravity of the machine body, and the like, a plurality of types of display panels 23 may be prepared corresponding to each model. 27 is a fixture. The mounting position of the inclinometer 22 can be appropriately selected if it is located in front of the driver's seat 24. However, in this embodiment, it is mounted above the operation panel 13 at the lower inside of the windshield, so that the operator M in the sitting posture can see the vehicle forward. I made it the best to see as it is.

The inclinometer 22 according to the present invention is attached to an easily visible part in front of the driver's seat 14 so that the pointer 24 can be swung in the left and right directions, and when the aircraft is run, the inclinometer 22 responds to the tilt in the machine width direction. The pointer 24 rotates and the pointer 24 always points in the vertical direction with respect to the horizontal plane h due to gravity, but when the work vehicle 1 is horizontal with respect to the left and right in the traveling direction, that is, there is no inclination, as shown in FIG. The tip of 24 points to 0 degrees, which means that there is no danger of falling and it is safe. However, when the work vehicle 1 travels and works along the contour line of a sloping ground, for example, as shown in FIG. 2, the left side is the mountain side, the right side is the valley side, and the pointer 24 points at 25 degrees. Should be careful about falling down. In addition, if the tilt angle becomes even greater than 30 degrees, there is a risk of the aircraft tipping over, so the aircraft will stop running and work. By the way, according to the present invention, the rotation area of the pointer 24 is colored blue and the caution area b is colored yellow according to the scale 26 of the tilt angle according to the number indicating the tilt angle on the surface of the display board 23. , The danger area c is displayed in red, so that the general public is familiar with all traffic signals: blue (safety), yellow (caution), red (danger), that is, running work OK, be careful. It is now possible to intuitively and immediately decide whether to stop driving or to stop work due to danger, and to deal with each case quickly so that you can perform safe work without falling.
