Specific implementation mode
With reference to Fig. 1 to Fig. 3, the utility model is described in further detail.
Refering to fig. 1, Fig. 2, a kind of automatic pressure-like device of heavy metal-polluted soil instrument, including pedestal 10 are provided on pedestal 10
Pressure sensor 20, sample slot 30, driving unit 40, pressing plate 50 and man-machine interaction unit 60, sample slot 30 is for holding soil
Earth sample, pressure sensor 20 are used to measure the weight of soil sample and export to man-machine interaction unit 60 and show, driving unit
40 for by pressing plate 50 be pressed into sample slot 30 in, operating personnel by man-machine interaction unit 60 control driving unit 40 startup and
Stop.By the way that pressure sensor 20 is arranged, it is ensured that the soil sample weight being added in sample slot 30 every time is consistent, and driving is single
Member 40 drives 50 automatic compacting soil sample of pressing plate, can be to avoid the error that manual operation is brought, and can ensure to press every time
Stroke it is consistent, the soil sample pressure of such discharge by pressing is balanced, tight ness rating is consistent.
Preferably, fluted 11 profile and sample for placing sample slot 30 and groove 11 is opened up on the pedestal 10
The outer profile of slot 30 matches, said herein to match, and refers to that the profile of groove 11 is slightly larger than the outer profile of sample slot 30, this
Sample sample slot 30 can be placed in groove 11 but will not be subjected to displacement.It is arranged after groove 11, it can be to avoid sample slot 30
It moves, ensures that soil sample compacting process is more acurrate.Sample slot 30 is positioned over one end in groove 11 and passes through plastic packaging film 31
Plastic packaging film 31 is arranged in sealing, is the X-ray test side for contacting Soil K+adsorption instrument for convenience；The other end of sample slot 30 is opened
Mouthful, it can thus facilitate pressing plate 50 to be pressed into from the other end of sample slot 30.Slot of 20 fixed placement of pressure sensor in groove 11
On bottom, pressure sensor 20 selects the sensor of that plane stress, range that can be selected according to the weight of soil sample, ruler
It is very little to be selected according to the size of groove 11.
Preferably, the driving unit 40 includes holder 41, motor 42, push rod 43 and clip 44；Holder 41 is whole to be in
" 7 " shape, lower end are fixedly mounted on pedestal 10, and push rod 43 is arranged at the suspension end of holder 41, and holder 41 is mainly used for propping up
Support push rod 43；Motor 42 is moved up and down by gear, axis and chain drive push rod 43, and the power of motor 42 is converted into driving
The up and down action of push rod 43, this has very more embodiments in the prior art, such as in the present embodiment, and motor 42 is directly logical
The rotation of chain-driving first gear is crossed, which drives second gear to rotate by axis, in second gear and push rod 43
Rack constitutes rack-and-pinion cooperation, to realize the up and down motion of push rod 43.Clip 44 is screwed mounted on push rod 43
Lower end, clip 44 is for being clamped pressing plate 50.Be arranged clip 44 after, can after 50 compacting soil sample of pressing plate with push rod 43
Phase separation can allow the two to detach when separation with the clamping of manual control clip 44；Chucking power can also be selected weaker
Clip 44 both allows separation by being arranged in sample slot 30 for the protrusion 32 of non-return and the weight of sample slot 30.Here
Why pressing plate 50 is stayed in sample slot 30, is needed sample slot 30 in turn, pressing plate 50 stays in it because when detecting
In can spill to avoid soil sample come.
Further, the sample slot 30 is circular tube shaped；Pressing plate 50 includes press section 51 and grip part 52, and press section 51 is whole
Body is in a circular table shape, and the lower end diameter of round platform is less than upper end diameter and upper end diameter matches with the internal diameter of sample slot 30, it is upper greatly under
Small press section 51 can be easily pressed into sample slot 30.Grip part 52 is clamped in rod-shaped for clip 44.
It stays in sample slot 30 in order to facilitate pressing plate 50, here preferably, is arranged on the inside tube wall of the sample slot 30
Have raised 32, the press section 51 of pressing plate and protrusion 32 constitute unidirectional insertion, the cooperation of reversed non-return.Protrusion 32 can be along sample slot 30
3 or 4 are uniformly arranged on interior circumferencial direction.
Preferably, the inside tube wall of the sample slot 30 is upper is provided with block 33 in 32 lower section of protrusion, and block 33 is used for
Limit the stroke that pressing plate 50 presses down on.It is arranged after block 33, without selecting driving unit 40 with high accuracy, driving unit 40
Output power crush board 50 is only needed to move downward, pressing plate 50 can be blocked after moving to 33 position of block, thus
It can guarantee that each tight ness rating is consistent；If being not provided with block 33, need to accurately control the stroke that push rod 43 moves downward, this
Requirement of the scheme to motor 42 is more slightly higher.
Preferably, the man-machine interaction unit 60 includes display screen, starts button and pressure-like button, operating personnel's pressing
Pressure sensor 20 starts to acquire the weight of soil sample and be shown on a display screen when starting button, operating personnel's pressing
40 driving push rod 43 of driving unit moves downward and with 50 compacting soil of dynamic pressure plate when pressure-like button.Man-machine interaction unit 60 is set
Afterwards, it may be convenient to which the present apparatus is controlled.After starting beginning button, pressure sensor 20 is started to work, at this moment manually
Soil sample is inserted to sample slot 30, and adds or reduces according to the weight of display screen display, until institute in sample slot 30
The soil sample weight held restarts pressure-like button after being equal to setting value, ensures that soil sample weight before each pressure-like in this way
Amount is consistent.
