SUMMERY OF THE UTILITY MODEL

To prior art not enough, the utility model provides an kinds of soybean anti-lodging dynamometer has solved the dynamometer of current rice or maize, is used in probably leading to instrument sensitivity to lack and do not have fixed strong point on the soybean, can't weigh the problem that fixed angle just stopped the meter power.

In order to achieve the purpose, the utility model adopts the technical scheme that soybean lodging-resistant dynamometers comprise a dynamometric device and a detecting head, wherein the detecting head is connected with the dynamometric device through a detecting rod, the dynamometric device is hinged with a scale rod through a connecting plate, an angle indicating disc is arranged at the hinge position of the measuring head, an angle indicating line corresponding to the angle indicating disc is arranged on the connecting plate, a foot rest and a level gauge are arranged on the scale rod, and the scale rod is of a multi-section type telescopic structure.

And , the front end of the probe is arc fork shaped, and the back part of the probe is provided with parallel rod shaped.

And , the connecting plate is hinged to the back of the force measuring device.

And , the angle indicating disc is made of transparent material and is provided with an angle indicating scribed line.

And step , the foot rest is movably connected with the scale rod.

And , the force measuring device is a spring force measuring device.

The utility model provides an kinds of soybean anti-lodging dynamometer possesses following beneficial effect:

the utility model discloses, through foot rest and scale pole swing joint, the rethread levelling instrument is made level, the fixed foot rest, the scale pole is telescopic pipe joint connection, after the levelling instrument is made level, can be according to soybean plant type and the position of highly definite survey, thereby improve sensitivity, be equipped with the angle indicating dial that transparent material has the angle indication groove through hinge department, be equipped with the angle indicating line that corresponds angle indicating dial on the same connecting plate, be convenient for measure at the experimental operation in-process 45 degrees angles, be the arc fork shape through the detecting head front end, the rear portion is equipped with parallel bar shape, increase the area of contact of detecting head and testee for the testee can the atress more even at the dynamometry in-process, the utility model discloses the simple operation, the practicality is strong, is convenient for push away use, has solved the dynamometer of current rice or maize, is used in probably leading to the instrument sensitivity lack and has not fixed strong supporting point on the soybean, can's unable problem of stopping power of measuring to.

Drawings

Fig. 1 is a schematic structural view of the soybean lodging-resistant dynamometer of the present invention.

In the figure, 1-a force measuring device, 2-a probe, 3-a hinge, 4-a scale rod, 5-a foot rest and 6-a level gauge.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, examples of which are shown in the drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements, unless otherwise indicated.

As shown in figure 1, the utility model provides an kinds of soybean anti-lodging dynamometers, including measuring device 1 and detecting head 2, measuring device 1 is the spring dynamometer, gives forces that push down for the testee through detecting head 2 to give measuring device 1 with the power of receiving, the front end of detecting head 2 is the arc fork shape, and the rear portion is equipped with parallel rod shape, and detecting head 2 is connected with measuring device 1 through the detecting rod, measuring device 1 is articulated with scale pole 4 through the connecting plate, and its hinge 3 department is equipped with the angle indicator dish, the angle indicator dish is transparent material, and the higher authority is equipped with the angle indication groove, be equipped with the angle indicating line that corresponds the angle indicator dish on the connecting plate, the connecting plate articulates the back at measuring device 1, be provided with foot rest 5 and spirit level 6 on scale pole 4, multistage formula 5 and scale pole 4 swing joint, scale pole 4 is flexible structure.
