Description
Technical field
A kind of test device is the utility model is related to, particularly a kind of device for determining soil filtration rate.
Background technology
At present, the bioassay standard foundation of soil filtration rate is：People's Republic of China's forestry industry standard（LY/T1218-
1999）.Using diafiltration cylinder method and core cutter method measure in the standard, the method in soil filtration rate continuous mode, mainly using
It is core cutter method.According to laboratory during soil filtration rate is determined, it is necessary to take sample at one for core cutter method
An idle loop knife is put above the cutting ring of product, interface is first sealed with adhesive plaster, then is bonded with dewaxing, operates more complicated, data
Accuracy it is relatively low, influence operating efficiency.
Utility model content
The purpose of this utility model is just to provide a kind of dress for enabling to the high measure soil filtration rate of data accuracy
Put.
The purpose of this utility model realized by such technical scheme, a kind of device for determining soil filtration rate,
Described device includes upper shell and lower shell, and the upper shell external wall of upper portion is provided with cutting ring, the bottom of the upper shell with
The top of lower shell is connected through a screw thread mechanism connection.
Interim, the threaded connection includes the plastic ring A being arranged on upper shell lower end outer wall and is arranged on down
Plastic ring B on the outer wall of cylinder upper end, the plastic ring A are connected with plastic ring B by thread mechanism.
Further describe, the thread mechanism include be arranged on the plastic ring A lower surface anti-clockwise thread and
It is arranged on the plastic ring B upper surfaces and the clockwise thread coordinated with anti-clockwise thread.
In order to be closed, cover A and cover B are respectively arranged with the upper shell upper end and lower shell lower end.
Flowed out for the ease of liquid, multiple circular apertures are provided with the cover B.
By adopting the above-described technical solution, the utility model has, simple in construction, cost is cheap, simple operation it is excellent
Point, the operation of personnel can be facilitated using it, save the time, improve operating efficiency, simultaneously, moreover it is possible to so that data is accurate
Property is higher.
Brief description of the drawings
Brief description of the drawings of the present utility model is as follows：
Fig. 1 is the first status architecture schematic diagram of the present utility model；
Fig. 2 is second of status architecture schematic diagram of the present utility model.

These embodiments are not limited to, any improvement or replacement on the present embodiment essence spirit, still fall within the utility model
Claim scope claimed.
Embodiment 1：As shown in Figure 1, 2, a kind of device for determining soil filtration rate, described device include upper shell 1 with
Cylinder 2, the external wall of upper portion of upper shell 1 is provided with cutting ring 10, the bottom and the top of lower shell 2 of the upper shell 1 pass through
Threaded connection connects.
Wherein, above-mentioned threaded connection includes the plastic ring A3 being arranged on the lower end outer wall of upper shell 1 and is arranged on
Plastic ring B4 on the upper end outer wall of lower shell 2, the plastic ring A3 are connected with plastic ring B4 by thread mechanism.
Further describe, the thread mechanism include be arranged on the plastic ring A3 lower surface anti-clockwise thread 5 with
And it is arranged on the plastic ring B4 upper surfaces and the clockwise thread 6 coordinated with anti-clockwise thread 5.
For the ease of closing upper shell and lower shell, cylinder is respectively arranged with the upper end of upper shell 1 and the lower end of lower shell 2
Cover A7 and cover B8.
Flowed out for the ease of liquid, multiple circular apertures 9 are provided with the cover B8.
The utility model so uses：Sampling work is carried out using the upper shell 1 with knife ring 10, then, by under
Cylinder 2 is attached with upper shell 1 by the plastic ring A3 with anti-clockwise thread 5 and clockwise thread 6 and plastic ring B4.
