Abstract
The utility model discloses a kind of soil hardness measuring instrument, the utility model comprises support, rocking bar, hardness display disc, spring and stationary links, described support is fixedly installed in the horizontal plane, described support is provided with the first sounding rod and the second sounding rod, described stationary links is provided with between described first sounding rod and described second sounding rod, described stationary links is connected with one end of described spring, the other end of described spring is connected with the pointer of described hardness display disc, and described rocking bar is arranged on described support.The utility model drives the first sounding rod and the second sounding rod to carry out upstream or downstream action by the rocking bar be arranged on support, realizes the test to the soil hardness of surface level by sounding rod elastically-deformable displacement in the horizontal plane.
Description
Technical field
The utility model relates to a kind of data measurement unit, refers more particularly to a kind of soil hardness measuring instrument.
Background technology
Time in the testing process of soil hardness, usually read the impression depth of displacement of soil, then table look-up and draw corresponding ball hardness number, this kind of method efficiency is low, and by the impact of the factors such as survey crew and soil surface smooth finish, measuring result error is larger.
Utility model content
It is simple that the purpose of this utility model is just to provide a kind of structure to solve the problem, the soil hardness measuring instrument that measuring accuracy is high.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises support, rocking bar, hardness display disc, spring and stationary links, described support is fixedly installed in the horizontal plane, described support is provided with the first sounding rod and the second sounding rod, described stationary links is provided with between described first sounding rod and described second sounding rod, described stationary links is connected with one end of described spring, the other end of described spring is connected with the pointer of described hardness display disc, and described rocking bar is arranged on described support.
Particularly, measurement base is provided with bottom described first sounding rod and described second sounding rod.
Particularly, described first sounding rod and described second sounding rod and described support are threaded connection.
The beneficial effects of the utility model are:
The utility model drives the first sounding rod and the second sounding rod to carry out upstream or downstream action by the rocking bar be arranged on support, realizes the test to the soil hardness of surface level by sounding rod elastically-deformable displacement in the horizontal plane.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-first sounding rod, 2-rocking bar, 3-second sounding rod, 4-vertical survey wall, 5-stationary links, 6-spring, 7-hardness display disc, 8-support.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, the utility model comprises support 8, rocking bar 2, hardness display disc 7, spring 6 and stationary links 5, described support 8 is fixedly installed in the horizontal plane, support 8 can be fixed on vertical survey wall 4 and and plane-parallel, described support 8 is provided with the first sounding rod 1 and the second sounding rod 3, described stationary links 5 is provided with between described first sounding rod 1 and described second sounding rod 3, described stationary links 5 is connected with one end of described spring 6, the other end of described spring 6 is connected with the pointer of described hardness display disc 7, described rocking bar 2 is arranged on described support 8.
Measurement base is provided with bottom described first sounding rod 1 and described second sounding rod 3, can suitably increase tested area, reduce the infringement to sounding rod, increase the service life, described first sounding rod 1 and described second sounding rod 3 are threaded connection with described support 8, support 8 carries out upstream or downstream action by rocking bar 2, realize the test to the soil hardness of surface level, adopt three-point circle function method to calculate displacement and with the spring constant of the spring selected in advance on hardness display disc, compared by standard hardness value and draw the ball hardness number of tested surface level, the test to the soil hardness of surface level is realized by sounding rod elastically-deformable displacement in the horizontal plane.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included in protection domain of the present utility model.
