The utility model relates to sample collection device technical field, concretely for water sample automatic continuous sampler, including rustproof shell, collection subassembly, collection subassembly includes trace peristaltic pump, trace peristaltic pump fixedly connected in the inside of rustproof shell, one side of trace peristaltic pump is fixedly connected with sampling hose, one side of sampling hose is provided with anti -blocking filter head hole. The water sample automatic continuous sampler, through installing collection subassembly, can realize that the front end of sampling hose is connected with screen filter and 50 -mesh filter head, is used to pretreat water sample, prevents impurity and blocks sampling system, and trace peristaltic pump is equipped with LED display screen, and the sampling frequency and sampling cycle can be adjusted, so as to adjust sampling mode and cycle according to actual demand, ensure accurate sampling, and the collected sample will enter the sampling bottle from the other end, adopt this kind of structure to make the whole sampling system can be safely and stably maintained in rustproof shell, and then it is convenient to sample under complex environment.
