Description
Technical field
The present invention relates to agriculture sampling appliance fields, more particularly, to a kind of Soil K+adsorption sampler of agricultural.
Background technique
Soil is the mixing component part of mineral and organic matter, the exploitation of soil is also further being deepened, to ring
The consciousness of guarantor is also constantly being paid attention to by every field, has become essential one for the investigation of soil contamination grade
Part.It needs to use soil sample collector when being sampled soil.
There are many types for soil sampler.Farmland or wasteland topsoil sample are acquired, small-sized spades can be used.
Study the general physical property of soil, such as soil weight, porosity and water retention characteristic etc., using cutting ring.Cutting ring is
The cylinder of both ends open, lower mouth have sword, and the height and diameter of cylinder are 5cm or so.
The most common soil sample tool is earth boring auger.Earth boring auger is divided to manual operations and two class of mechanically actuated.Manually operated soil
Brill style is a lot of, there is the short handle earth boring auger of acquisition thin solum, the screw earth boring auger of observation 1m or so soil layer interior profile feature, Hou Zhejin
Soil is laborsaving, is particularly suitable for observation WATER LEVEL CHANGES, but it is small to acquire sample amount.Acquire for chemical analysis or be not required to the object of undisturbed soil
When managing the soil sample of analysis, with open type earth boring auger.Acquisition does not destroy the undisturbed soil sample of soil texture or shape, uses telescopic earth
It bores.
Machinery is adopted soil and is driven by motor, so that drill body is entered the soil of certain depth, then puts on earth pillar, lays flat observation,
Cutting sampling as needed.Soil diameter can be controlled with the drill body of different-diameter, such as 5cm, 10cm or thicker.Power auger efficiency
Height can save manpower, but flexible, light not as good as hand drill.

End has been bolted push plate 1, and the 3 outer wall upper end of cylinder is symmetrically welded with fixed plate 5, welds below the fixed plate 5
There is securing plate 4, described 4 one end of securing plate is welded as a whole with 3 outer wall of cylinder, is welded on 5 upper surface of fixed plate
Fixing sleeve 13 is equipped with stud 9 by screw thread on the fixing sleeve 13, is rotatably connected to pivoted housing 6 on the stud 9, and described turn
It covers 6 sides and is welded with crossbeam 8,8 end of crossbeam forms pedal shaft 15, and 15 outside of pedal shaft is equipped with by bearing
Pedal 7,15 outer end of pedal shaft are equipped with locking cap head 17 by screw thread, and 9 tail portion of stud is installed by screw thread
There is end cap head 10.
Further, 14 tail portion of guide post is fixed with rotation seat 12 by pin shaft, passes through pin on the rotation seat 12
Axis is fixed with handle 11, and the handle 11 can carry out 90 degree of rotation, by hold the handle 11 can outward or to
Interior mobile push plate 1, the handle 11 that can choose are exerted oneself when being easy to use.
Further, there are two the fixed plate 5 is total to, the fixed plate 5 is not less than eight millimeters of steel plate system using thickness
At service life can be improved by high-intensitive material.
Further, the pedal 7 is made of ABS quantity, and 7 upper and lower surface of pedal forms anti-skid chequer
16, increase frictional force, avoid using when occur to skid it is injured.
Further, the push plate 1 is the disc-shaped structure that diameter is 5cm-20cm, and the push plate 1 is slidably connected at institute
It states inside cylinder 3, the diameter of the push plate 1 is identical as the internal diameter of the cylinder 3, can will be inside cylinder 3 by the push plate 1
Soil sample is sent out.
Further, 3 end of cylinder is provided with arc-shaped tungsten alloy pointed cone 18,18 lower end of tungsten alloy pointed cone
The intilted conical surface 21 that buries is formed on outer surface, 18 lower end width of tungsten alloy pointed cone is one millimeter, tungsten alloy material
Material improves service life, and the conical surface conveniently buries.
Further, interior positioning step 22, the interior positioning step 22 are formed on the inside of 18 upper end of tungsten alloy pointed cone
On be welded with interior buckle 19, two interior buckles 19 are welded on the every tungsten alloy pointed cone 18, the interior buckle 19 is adopted
It is made of spring steel.
Further, the inner card cage 20 being coupled with interior buckle 19 is formed on 3 inner wall of cylinder, it can be from inside
Complete the fixed installation of the tungsten alloy pointed cone 18.
Further, integrally formed with outer positioning convex platform 23, the outer convex on the inside of 18 upper end of tungsten alloy pointed cone
