Technical field
The utility model belongs to detecting instrument, relates generally to the soil liquid harvester that there is water layer on the ground such as a kind of rice field, wetland, marsh.
Background technology
Analyze the hot issue that the soil liquid detecting crop growth period is irrigation and water conservancy subject.The soil liquid is easily by the impact of surrounding environment, and especially in the environment of paddy field, due to the existence of water layer, sampling is difficult, large to plant growth disturbance.Paddy-field soil solution sampling device in the past adopts principle of negative pressure to extract usually, extracts difficulty, thorough after sample collection, simultaneously easily has an impact to plant growth.Be badly in need of a kind of undisturbed collection of exploitation, thoroughly extract the device of the soil liquid fast.
Utility model content
The purpose of this utility model is exactly for above-mentioned prior art Problems existing, according to the actual needs of agricultural production, a kind of adding pressure type paddy-field soil solution of research and design in-situ sampler, is intended to solve the prior art soil liquid and gathers disturbance greatly, extract difficulty, halfway shortcoming.
For achieving the above object, design proposal of the present utility model is: adding pressure type paddy-field soil solution in-situ sampler, it comprises cylinder, cylinder upper portion side wall is provided with pore, middle part is provided with infundibular body, infundibular body is connected with fluid reservoir by reverse checkvalve, and solution efferent duct and gas piping are sealedly attached to bottom and the top of fluid reservoir respectively, and gas piping is connected with pressue device.
Described reverse checkvalve is inlet non return check valve, and top seal connects infundibular body lower seal and connects fluid reservoir.
Described pressue device is foot-operated inflating function cylinder.
Described solution efferent duct and gas piping are rubber flexible pipes.
The utility model has following beneficial effect:
In use, cylinder is all imbedded in the paddy field soil being in state of saturation in Crop growing stage, the soil liquid in paddy field flows through pore and enters in the infundibular body that sealing is arranged under it, fluid reservoir is entered by infundibular body bottom reverse checkvalve, this inlet non return check valve must be tightly connected with infundibular body and fluid reservoir, by the effect of inlet non return check valve, be tightly connected with solution efferent duct bottom fluid reservoir, fluid reservoir top and gas piping are tightly connected, gas piping outer end is exposed earth's surface and is connected with pressue device, this pressue device is a foot-operated inflating function cylinder, under the effect of pressue device, gas carries fluid reservoir through gas piping, increase gas pressure intensity in it, solution in fluid reservoir is under inside and outside differential pressure effect, earth's surface is transported to by solution efferent duct, received by other receiving vessels, complete paddy field solution collection operation.Gas piping and solution efferent duct all adopt rubber flexible pipe, and plasticity is good, and accommodative ability of environment is strong.
The utility model is according to hydrostatic pressure feature, adopt filter press technique, for the physical characteristics of paddy-field soil solution, overcome the shortcoming of prior art, there is the collection of original position undisturbed, extract paddy-field soil solution fast, thoroughly, parts disassembly and assembly are convenient, lightweight, be easy to carry, with low cost, Operation and Maintenance simple, be applicable to continuously or irregularly gather the feature used.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is one-piece construction front view (FV) of the present utility model.
In figure: 1-cylinder, 2-pore, 3-infundibular body, 4-reverse checkvalve, 5-fluid reservoir, 6-solution efferent duct, 7-gas piping, 8-pressue device.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
See Fig. 1, adding pressure type paddy-field soil solution in-situ sampler, it comprises cylinder 1, cylinder 1 upper portion side wall is provided with pore 2, middle part is provided with infundibular body 3, infundibular body 3 is connected with fluid reservoir 5 by reverse checkvalve 4, and solution efferent duct 6 and gas piping 7 are sealedly attached to bottom and the top of fluid reservoir 5 respectively, and gas piping 7 is connected with pressue device 8.
Preferably, described reverse checkvalve 4 is inlet non return check valves, and top seal connects infundibular body 3 lower seal and connects fluid reservoir 5, can ensure in plenum process in fluid reservoir 5 by the effect of reverse checkvalve 4, ensure that gas can not leak, thus solution is exported smoothly by solution efferent duct 6.
Preferably, described pressue device 8 is foot-operated inflating function cylinders, adopts this pressue device easy to use and flexible, is easy to carry.
Preferably, described solution efferent duct 6 and gas piping 7 are rubber flexible pipes, adopt hose construction to facilitate the installation of device.
The utility model device specific works principle and the course of work are:
When needing to carry out soil liquid in-situ sampling, first, cylinder 1 is all imbedded in the paddy field soil being in state of saturation in Crop growing stage, the soil liquid in paddy field flows through pore 2 and enters in the infundibular body 3 that sealing is arranged under it, fluid reservoir 5 is entered by infundibular body 3 bottom reverse checkvalve, this inlet non return check valve must be tightly connected with infundibular body 3 and fluid reservoir 5, by the effect of inlet non return check valve, be tightly connected with solution efferent duct 6 bottom fluid reservoir 5, fluid reservoir 5 top and gas piping 7 are tightly connected, gas piping outer end is exposed earth's surface and is connected with pressue device 8, under the effect of pressue device 8, gas carries fluid reservoir 5 through gas piping 7, increase gas pressure intensity in it, solution in fluid reservoir 5 is under inside and outside differential pressure effect, earth's surface is transported to by solution efferent duct 6, received by other receiving vessels, complete paddy field solution collection operation, gas piping 7 and solution efferent duct 8 all adopt rubber flexible pipe, plasticity is good, accommodative ability of environment is strong.
Principle of work of the present utility model is: by the effect of reverse checkvalve 3, and cylinder 1 point is extracted two large divisions in order to top solution collection and bottom solution, reaches the effect of " can catchment and air tight "; Through the pressure process of pressue device, the pressure in fluid reservoir 5 is apparently higher than Earth Surface Atmosphere pressure, so the solution in fluid reservoir 5 flows out rapidly, up hill and dale under inside and outside differential pressure effect, and for plant growth and the impact of surrounding soil undisturbed.
