Facilitate, can not be influenceed by environmental light brightness, the daytime measurement of operator on the tractor's forward view can be realized, be not required to
Visual field schematic diagram is easily drawn out in the case of drawing shielding shadow, measurement accuracy and operating efficiency is further increased.
Brief description of the drawings
Fig. 1 is a kind of main structure diagram of operator on the tractor's forward view measurement apparatus of the utility model；
Fig. 2 is a kind of left view structural representation of operator on the tractor's forward view measurement apparatus of the utility model；
Fig. 3 is a kind of overlooking the structure diagram of operator on the tractor's forward view measurement apparatus of the utility model.
Embodiment
The utility model will be further described below in conjunction with the accompanying drawings.As shown in Fig. 1 ~ 3, before a kind of operator on the tractor
Visual field measuring device, including：Box style substructure 1, gimbals 2, measurement laser 3, fixed support 4, Universal level-metre 5, switch
6th, connecting rod 7, horizontal rotation handle 8, pitch angle adjustment handle 9, positioning laser 10；It is characterized in that：In the upper table of box style substructure 1
Face both sides are provided with two gimbals 2, and fixed support 4, and fixed support 4 are additionally provided with the upper surface middle part of box style substructure 1
On center line between two gimbals 2, measurement laser 3 is provided with two gimbals 2, in fixed support
Positioning laser 10 is provided with 4, horizontal rotation handle 8 is provided with two gimbals 2, for controlled level direction
Rotation, is provided with connecting rod 7 between two gimbals 2, is remained for limiting two gimbals 2 in rotary course
65mm spacing, is provided with pitch angle adjustment handle 9, the adjustment for controlling pitch angle on connecting rod 7.
Switch 6 is provided with the side of box style substructure 1, the opening and closing for controlling measurement laser 3 and positioning laser 10,
It is additionally provided with the upper surface of box style substructure 1 for integrated model level whether Universal level-metre 5 to be detected.In box style substructure 1
In the case of holding level, the beam direction of the positioning laser 10 on fixed support 4 should be perpendicular to passing through two gimbals
The vertical guide of 2 center of rotation lines.
Box style substructure 1 is set by other auxiliary, is arranged on driver seat, and can in the horizontal direction be done around servicing unit
360 ° of rotations.
