Description
Technical field
The present invention relates to a kind of soil water meauring instrument.
Background technology
Soil water meauring instrument is called Soil Tension, a kind of instrument for measuring soil water potential, including a survey
Test tube, the lower end of testing tube is popped one's head in equipped with ceramics, the upper end of testing tube be equipped with vacuum dial plate, the water filling port of upper end be provided with it is close
Tensometer, is arranged in soil by capping during test, and ceramics probe is in close contact with soil, and the water in testing tube is visited by ceramics
Head is penetrated into soil, with the reduction of rate of water added, occurs partial vacuum inside testing tube, air pressure becomes on negative value, vacuum dial plate
Pointer changes with the change of vacuum, and shows, until the water in testing tube is when no longer reducing, and pointer is just not
Swing again.
The capillary tension head that Soil Tension is measured is exactly suction of the soil to water, and soil is wetter, and the suction of water is just cured
It is small, on the contrary it is then big, and when soil moisture increases to all spaces full of water, capillary tension head will be reduced to zero.
Existing viewing area be all with numeral indicated and unit is bar, needed after reading numerical values by the table of comparisons
Water regime of soil can just be concluded to instruct to irrigate.
Existing Soil Tension is primarily present two problems：First, being not yet put into ceramics probe in soil, ceramics
Probe has just been saturated with water, so places into soil and may result in some errors；Second, being put into by ceramics probe in soil
Cause moisture to penetrate into soil so that ceramics probe is often acutely rocked during being in close contact with soil and be not
The result of real capillary tension head effect.
The content of the invention
It is an object of the invention to：A kind of Soil Tension is provided, the technical problem that background section is proposed is solved.
In order to solve the above technical problems, the technical solution adopted in the present invention is：A kind of soil water meauring instrument, bag
Include hollow circular-tube, vacuum dial plate, filler neck seal lid, elastic caoutchouc dividing plate, elastic dome rubber plugging sheet, pulling force rope and pottery
Porcelain is popped one's head in；
The both ends open of described hollow circular-tube；
The upper port of described hollow circular-tube is filler, and the upper port of hollow circular-tube sets filler neck seal lid；
The top of described hollow circular-tube sets vacuum dial plate；
The lower port of described hollow circular-tube sets elastic caoutchouc dividing plate, and the lower section of elastic caoutchouc dividing plate sets ceramics to visit
Head；
An otch is provided with described elastic caoutchouc dividing plate, the otch is V-shaped, the otch relies on the bullet of itself
Power can be closed automatically, (be that suitable order generation is negative when the pressure above elastic caoutchouc dividing plate is more than the pressure of lower section
Pressure), the otch on elastic caoutchouc dividing plate can be automatically opened up；
The corresponding position of the lower section of described otch sets elastic dome rubber plugging sheet, elastic dome rubber envelope
It is fixedly connected between the certain point of jam and elastic caoutchouc dividing plate；
One end of described pulling force rope is connected to elastic dome rubber plugging sheet, and the other end is located at pottery through ceramics probe
The outside of porcelain probe.
Further, described pulling force rope is through ceramics probe but will not damage ceramic probe.
Further, described elastic dome rubber plugging sheet is placed exactly in the water inlet of ceramics probe.
Compared with prior art, the advantage of the invention is that：First, not yet it is put into soil, relies in ceramics probe
Elastic dome rubber plugging sheet blocks the otch on elastic caoutchouc dividing plate, accordingly even when suitable order is with the presence of negative pressure,
Water still may not flow into ceramics probe, after ceramics probe, which is deep into all in soil, to be ready to, be pulled up with hand
Pulling force rope, at this moment the otch on elastic caoutchouc dividing plate can open, water be slowly deep into ceramics probe in, soil it is more dry to ceramics spy
The water in more how such hollow circular tube that water in head absorbs just constantly is supplemented to ceramics probe, unlike attraction meter before exists
Ceramics probe is just permeated with a large amount of water to cause measurement error big when not yet measuring；Second, ceramics probe is being put into soil
Cause that ceramics probe is often acutely rocked but not yet water leaking-in in ceramics probe during being in close contact with soil in earth
So that measurement is more accurate.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Wherein, 1 is hollow circular-tube；2 be vacuum dial plate；3 be filler neck seal lid；4 be elastic caoutchouc dividing plate；5 be elasticity
Hemispherical rubber plugging sheet；6 be pulling force rope；7 be ceramic probe.
Embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
Specific embodiment：A kind of soil water meauring instrument, including hollow circular-tube, vacuum dial plate, filler neck seal lid, bullet
Property rubber separator, elastic dome rubber plugging sheet, pulling force rope and ceramics probe；The both ends open of described hollow circular-tube；Institute
The upper port for the hollow circular-tube stated is filler, and the upper port of hollow circular-tube sets filler neck seal lid；Described is hollow
The top of pipe sets vacuum dial plate；The lower port of described hollow circular-tube sets elastic caoutchouc dividing plate, elastic caoutchouc dividing plate
Lower section sets ceramics probe；An otch is provided with described elastic caoutchouc dividing plate, the otch is V-shaped, the otch according to
Can be closed automatically by the elastic force of itself, the pressure above elastic caoutchouc dividing plate be more than lower section pressure when, elastic caoutchouc every
Otch on plate can be automatically opened up；The corresponding position of the lower section of described otch sets elastic dome rubber plugging sheet, bullet
It is fixedly connected between the certain point of property hemispherical rubber plugging sheet and elastic caoutchouc dividing plate；One end of described pulling force rope is connected to
Elastic dome rubber plugging sheet, the other end is located at the outside of ceramics probe through ceramics probe.
Wherein, described elastic dome rubber plugging sheet is placed exactly in the water inlet of ceramics probe.
The application method of the present invention：
The first step, ceramics probe is extend into soil so that ceramics probe is fully in close contact with soil to be measured；
Second step a, hand presses downwards the filler neck seal lid stated in residence, and another hand pulls up pulling force rope, at this moment bullet
Property hemispherical rubber plugging sheet in the presence of pulling force can be separated with elastic caoutchouc dividing plate, the suitable order on elastic caoutchouc dividing plate
Producing negative pressure causes otch to automatically open up, and the water in hollow circular tube is slowly flowed into ceramic probe.
