Technical field
The present invention relates to a kind of soil mechanical composition sample absorbing device.
Background technology
The degree of accuracy that sample is inhaled in semi-automatic soil mechanical composition can have a huge impact analytical work, and in the mensuration process of soil mechanical composition, inhaling sample is one of very important link.Inhale the improper meeting of sample and make analytical work be subject to direct impact, error appears in analysis result, analyzes data and departs from, and can not reflect detection truth-value.Soil mechanical composition is inhaled in the sample process, and the stationarity of the stability of absorption sample position, the time of inhaling sample, suction tube, suction sample speed is very important.At present, the laboratory is pipette method commonly, in required time in the suction pipe suction solution, inhale sample with rubber pipette bulb with hand-held suction pipe, shortcoming is that the depth error of pipette suction liquid level is larger, it is inhomogeneous to inhale sample speed, then the general solution that sucks first few scaleover line adjust liquid level in the pipette, makes its concave meniscus and scale mark level, easy disturbance solution, test error is large, the imbibition tube head pollutes easily, inefficiency.
Summary of the invention
The present invention is large for the depth error of pipette suction liquid level in the mensuration process that solves soil mechanical composition, suction sample speed is inhomogeneous, test error large, the imbibition tube head pollutes and ineffective problem easily, and a kind of semi-automatic soil mechanical composition sample absorbing device is provided.
The present invention solves the problems of the technologies described above the technical scheme of taking to be: described device comprises support, it is characterized in that described device also comprises steering wheel, horizontal rail, negative tube, vertical track, move horizontally minitrim wheel, move horizontally the coarse adjustment wheel, vertical sliding is used force and is transferred wheel, vertical mobile minitrim wheel, pipette, the negative pressure bucket, box body and a plurality of pipe clamp, each installation direction wheel of the supporting leg bottom of support, the upper surface of support is provided with horizontal rail, move horizontally minitrim wheel, move horizontally the coarse adjustment wheel, vertical sliding is used force and is transferred wheel to be rotationally connected with box body respectively with vertical mobile minitrim wheel, box body and vertical track are slidingly connected, moving horizontally the coarse adjustment wheel is arranged on the horizontal rail and the two connection of rolling, vertical sliding is used force and is transferred wheel to be connected with the vertical track rolling, each pipe clamp is packed on the vertical track, a plurality of pipe clamps are clamped pipette, move horizontally minitrim wheel and move horizontally coarse adjustment wheel engaged transmission, vertical mobile minitrim wheel and vertical sliding are used force and are transferred the wheel engaged transmission, and pipette is communicated with the negative pressure bucket by negative tube.
The present invention has following beneficial effect: owing to adopted accurate adjustment to inhale the sample location means, increase the accuracy of inhaling the sample position, adopt negative pressure suction quadrat method, make the absorption sample representativeness strong, suction tube adjusted by use machinery and negative pressure suction quadrat method is little to the dark liquid disturbance of settling vat.Inhale again sample behind each sample cleaning-drying, reduce the sample room cross pollution; Put simultaneously 1-50 sample at every turn, and draw at any time sample, improved work efficiency.The present invention compares raising degree of accuracy 22% with adopting conventional powder quadrat method, and work efficiency improves more than 20%, since sampling location, whole accurately location, the representativeness enhancing of sample.
