Abstract
The utility model provides a trees branch contained angle measuring device, includes protractor, wireless lighting camera, characterized by: it connects into four bar mechanism's rhombogen to be folded paper through the connection and measured to fold paper by four measurement boards, measures the outer fixed surface connection tooth -shaped location of boards for following two of the rhombogen and pitches, and now two measurement joining of platess departments fold paper for the measurement, above -mentioned measure articulated support connecting device on the board horizontal pole, the perpendicular telescopic link of horizontal pole fixed connection, fixed liquid crystal image receiver ware on the hypomere pole of perpendicular telescopic link, the base of while fixed connection protractor on this measures board, shang mian two initial points of measuring joining of plates department and protractor coincide, shang mian fix on another measurement board and set up angle pointer, simultaneously at angle pointer's side fixed connection wireless lighting camera. The utility model discloses measurement of efficiency height, convenient operation, simple structure, result accuracy.
Description
Technical field
The utility model belongs to a kind of forestry survey instrument, particularly a kind of tree limb angle measurement apparatus.
Background technology
Trees not of the same race, the angle between its branch and trunk is different, and the size at the branch angle determines the shape of tree crown
Shape, size, direction, height, especially play an important role during density of crop control, fine-variety breeding, community collocation,
Therefore the angle between research branch and trunk has great importance；And the angle measurement process between branch and trunk
In, it is very big by common protractor measure error because position is high, sample size is big, although commercially available digital display/numeral protractor
Accuracy rate is higher, but measurement efficiency is very low.Therefore a kind of new tree limb angle measurement apparatus are provided, is that forestry scientific research is adjusted
Look into using urgently.
Utility model content
The purpose of this utility model is to solve the above problems, there is provided a kind of tree limb angle measurement apparatus, practicality
By force, simple structure, easy to operate, it is adaptable to the efficient angle between measurement branch and trunk.
The technical scheme that the utility model is provided is as follows：Including protractor, wireless lighting camera, it is characterized in that：By four
Individual measurement plate connects into the rhombogen of four-bar linkage structure, two measurement plates below rhombogen by connecting folding and measurement folding
Outer surface is fixedly connected tooth shape locating fork, and the junction of following two measurement plate is measurement folding；Cut with scissors in a measurement plate above
The cross bar of support connection device is connect, cross bar is fixedly connected vertical telescopic bar, on the lowermost bar of vertical telescopic bar liquid crystal is fixed
Picture receiver；It is fixedly connected the base of protractor, the junction of both the above measurement plate and angulation in the measurement plate simultaneously
The origin of device overlaps；Above angle indicator is fixedly installed in another measurement plate, while the side in angle indicator is fixedly connected
Wireless lighting camera.
Good effect of the present utility model：Measurement efficiency is high, easy to operate, simple structure, result are accurate.
Description of the drawings
Fig. 1 is structure chart of the present utility model（Cross measure obtuse angle）.
Fig. 2 is the utility model longitudinally measurement acute angle schematic diagram.
Fig. 3 is angular surveying enlarged drawing of the present utility model.
Fig. 4 is tooth shape locating fork enlarged drawing.
Fig. 5 is vertical telescopic bar connection four-bar linkage structure rhombogen schematic diagram of the present utility model.
Specific embodiment
See Fig. 1-5, concrete structure is as follows：By four measurement plates 2-1,2-2,2-3,2-4 by connection folding 3 and measurement folding
Page 1 connects into the rhombogen of four-bar linkage structure, and two measurement plate 2-1,2-2 outer surfaces are fixedly connected profile of tooth and determine below rhombogen
Position fork 8, the junction of following two measurement plate 2-1,2-2 is measurement folding 1；Above hinged support connects in measurement plate 2-3
The cross bar 4-1 of connection device, cross bar 4-1 are fixedly connected vertical telescopic bar 4-2, fixed on the lowermost bar of vertical telescopic bar 4-2
Liquid crystal image receiver 9（Prior art）, while the base of protractor 5 is fixedly connected in measurement plate 2-3, both the above measurement
The junction of plate 2-3,2-4 overlaps with the origin of protractor 5.Above angle indicator 6 is fixedly installed in another measurement plate 2-4,
Simultaneously the side in angle indicator 6 is fixedly connected wireless lighting camera 7（Prior art）.
Operation principle：The rhombogen measurement plate for making four-bar linkage structure is naturally drooped, and according to the different height of crotch, is adjusted and is hung down
The length of straight expansion link, opens wireless lighting camera, and measurement apparatus are gently moved to the angle between branch and trunk,
Measurement folding 1 is slowly declined, treat that tooth shape locating fork 8 blocks the measurement plate of mobile jib and branch, i.e., parallel with trunk, another
Measurement plate is parallel with branch, according to rhombus（Parallelogram）Diagonal equal geometrical principle, device is made certainly using Action of Gravity Field
So reset.Due to digital display angle and measurement angle it is equal；Measurement angle side end is heavier, revert under gravity when unmeasured 0 ° or
Minute angle, and when measuring, be directly clamped among at the angulation between branch and trunk and exact numerical is obtained.By liquid crystal image
The screen viewing of receiver 9 is read.
