The present embodiment is got the suitable liquid getting device suction pipe 41 of liquid bulking value by one with target and is realized high precision and get liquid, for example, getting liquid measure is 10ml, the present embodiment is equipped with the liquid getting device suction pipe corresponding with 10ml, then by negative pressure generating device 43, liquid getting device suction pipe 41 is produced to negative pressure, make to be full of and to be got liquid in liquid getting device suction pipe 41, and excessive negative pressure flows in discharge container 42 liquid of being got in liquid getting device suction pipe 41, in the time of liquid getting device 4 inside and outside pressure balanced, in liquid getting device suction pipe 41, be full of and got liquid, in discharge container 42, some is got liquid, in discharge container 42 this part to be got liquid be no, because liquid getting device suction pipe 41 volumes are just in time corresponding with 10ml, therefore, as long as the liquid of being got in liquid getting device suction pipe 41 is transferred to and can be completed a high precision in target container and get liquid.What deserves to be explained is, liquid getting device suction pipe volume is corresponding with 10ml does not represent that liquid getting device suction pipe volume is 10ml, because consider that the surface tension of small volume of water solution and liquid getting device suction pipe are from being got the variation in water pressure while extracting out liquid liquid level, liquid getting device suction pipe volume can do some adjustment.
The stirrer 3 of the present embodiment has the function of timing braking, can set in advance program, after stirring Preset Time, automatically stop, send alerting signal simultaneously, remind user to stir, the mixed liquor after stirring is left standstill to 10 minutes, liquid getting device 4 automatically declines and gets liquid under crane 5 is controlled, after getting liquid and completing, crane 5 lifts liquid getting device 4 automatically, forwards target container liquid to and discharges.After release completes, sampler sends alerting signal again, reminds user that target container is taken away.
For measuring the sampling method of sampler for Stabilized Soil lime or cement dose, wherein, comprise the following steps:
Step 1, the soil sample of getting 300g fine grained soil join in sample receiver 2;
Step 2, in sample receiver 2, pour the ammonium chloride solution into 600ml into, and make the lower end of the mixed liquor submergence stirrer 3 of ammonium chloride solution and soil sample;
Step 3, turn on agitator 3 stir the mixed liquor of ammonium chloride solution and soil sample, and the mixing time of stirrer 3 is three minutes, and stirring number of times is per minute 110 times to 120 times;
Step 4, the mixed liquor after stirring is left standstill to 10 minutes, if supernatant does not still appear in mixed liquor, continue to leave standstill, until there is supernatant, control crane 5 liquid getting device 4 is fallen, make liquid getting device 4 lower end immersed in liquid level 1cm; The degree of depth of immersed in liquid level is indicated by mark post 51.
Step 5, control liquid getting device 4 draw the mixed liquor supernatant of 10ml;
Step 6, control crane 5 rise liquid getting device 4, make liquid getting device 4 lower ends leave sample receiver 2, and liquid getting device 4 is moved on target container, and the liquid in liquid getting device 4 is discharged in target container.
The usage of the liquid getting device 4 in the present embodiment is as follows:
Step 1, pressure relief opening 44 is kept closed, and liquid getting device suction pipe 41 lower ends is inserted got below liquid liquid level;
Step 2, make the interior generation negative pressure of discharge container 42 by negative pressure generating device 43, this negative pressure makes to be got liquid and flows in liquid getting device suction pipe 41;
Step 3, quilt are got liquid and are full of after liquid getting device suction pipe 41, continue to flow in discharge container 42, along with being got the inflow of liquid, negative pressure in discharge container 42 reduces gradually, until no longer flowed in discharge container 42 by being got liquid, now got that liquid is still full of liquid getting device suction pipe 41 and liquid getting device suction pipe 41 upper ends are not had by the immersion of being got in discharge container 42;
Step 4, will move to target container for the sampler of measuring Stabilized Soil lime or cement dose, and make liquid getting device suction pipe 41 lower end aligned target containers, open pressure relief opening 44, the negative pressure in discharge container 42 is disappeared, the liquid of being got in liquid getting device suction pipe 41 flows in target container.
Step 5: liquid getting device 4 is left to target container place, open the leakage hole 45 that is arranged on discharge container 42 bottoms, the liquid of being got in discharge container 42 is discharged.
Do not state part with the first embodiment.
The present embodiment can be realized robotization completely, use motor 31 to drive stirrer 3 to stir mixed liquor, control the lifting of liquid getting device by crane 5, due to adopted can accurate quantification liquid getting device suction pipe 41, only need in the time that immersing mixed liquor supernatant, liquid getting device 4 start one time negative pressure generating device 43, the size requirements of negative pressure is not high, as long as can make liquid getting device suction pipe 41 be filled, adopts simple mechanical combination to accomplish.Therefore, the scheme that the present embodiment provides can fully realize robotization, reduces manually-operated uncertainty, increases experimental precision.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although by the utility model being described with reference to preferred embodiment of the present utility model, but those of ordinary skill in the art is to be understood that, can make various changes to it in the form and details, and not depart from the spirit and scope of the present utility model that appended claims limits.
