PURPOSE:To insert a suction pipe for sampling shallowly and to prevent the suction pipe from damaging by mounting a sample pipe on slanting rollers and transporting it to a sampling position while slanting said sample pipe by using arms which appear and disappear between rollers. CONSTITUTION:When the sample pipe 1 is mounted on the rollers 3 which are arranged slantingly, the sample pipe 1 is transported from left rollers to right rollers in order through the elevating motion of arms 4 and 4 while stirring is carried out by the rotation of the rollers 3. When the pipe reaches the sampling position, the sample pipe 1 is pressed and fixed by a sample pipe pressing device 7. In this state, a sampling device 5 inserts the suction pipe 8 into the sample pipe 1 to sample its internal sample. Consequently, suction is carried out while the sample pipe 1 is slanted, so the insertion length of the suction pipe 8 becomes short. Therefore, the suction pipe is prevented from damaging owing to an increase in the insertion length. |
