Description

  The present invention relates to a shaking apparatus that simultaneously shakes a plurality of test containers in which a test solution is placed, and produces a large number of analytical solutions at a time.

  In recent years, environmental pollution has become a major social problem, and with regard to soil pollution, which is one of them, investigations of pollution status by various metals and volatile organic compounds contained in contaminated soil are urgent nationwide. Yes.

  In such a soil contamination survey, it is desirable to analyze the pollutants at the site of the soil contamination survey and quickly grasp the contamination status. However, in order to do so, it is necessary to bring analytical equipment to the site of the soil contamination investigation and prepare an analytical test solution from the test solution on the spot.

  In particular, when the range of soil contamination surveys is wide, the number of analysis targets increases, and in order to proceed with analysis quickly, it takes time to prepare a large number of analytical solutions at one time and prepare for analysis processing. Need to be shortened.

  As described above, as an apparatus for preparing a large number of analytical test solutions at one time, there is one as shown in Patent Document 1. This manufacturing device automatically conveys a plurality of test containers accumulated on a collection stand to a shaking device on a belt conveyor, and after shaking, automatically conveys them on a belt conveyor and accumulates them on a discharge stand at a time. A large number of analytical test solutions can be prepared. However, since such a manufacturing apparatus is large in size, it is difficult to transport to a survey site, and it takes a lot of economic burden and labor to move it.

  On the other hand, when using a small shaking device, although the burden on transportation and the like is reduced, in order to produce a large number of analytical solutions at the same time by shaking a plurality of test containers, It is necessary to prepare several shaking devices at the site of soil contamination investigation.

  The shaking method in the shaking device includes a so-called reciprocating method in which the shaking table is reciprocated in the width direction or the length direction of the shaking table, and the test container on the shaking table is shaken. A so-called swiveling method, in which the table is swung in a circular shape, an elliptical shape, an 8-shaped shape, etc., and the test container on the shaking table is swung, and the shaking table is swung around the support shaft. There is a so-called seesaw system in which the end in the width direction of the table is moved up and down, and the test container on the shaking table is shaken around a support shaft.

  Among these shaking systems, the seesaw type shaking device is simpler in structure, has fewer parts, and is lighter in weight than other shaking type shaking devices. It is highly convenient and is ideal as a shaking device used for preparing analytical solutions for analysis in the field where soil contamination is actually investigated.

  However, seesaw type shaking devices generally maintain small size and light weight on the shaking table because the test containers must be evenly arranged on both sides in the width direction so as to face the support shaft. However, it has been a problem to have a structure in which a large number of analytical test solutions can be prepared at one time like other shaking-type shaking devices.
