8. a kind of method of sampling of the acid rain automatic sampler of environment measuring described in claim 1~7, it is characterised in that:
Including,
Step 1: by the migration of positive four-wheel walking mechanism, sampling box (3) being pushed into Acid Rain Zone, and cover board (10) is in
Air-tight state.
Step 2: carrying out level-one debugging, it is conllinear with the longitudinal axis of sampling box (3) to make the longitudinal axis of two sampling cylinders (12), and make
Motor control module controls stepper motor (5) periodic rotary, state in stepper motor (5) a cycle: level-one is static-turns
Dynamic-second level is static, and the level-one static time is T1, and stepper motor (5) drives the rotation radian of first gear (20) to be when rotation
π, second level static time are T2.
Step 3: carrying out second level debugging, hydraulic module (2) is made to control to adjust mechanism periodically opening and closing cover board (10), cover board (10) one
State in a period: opening-closing-is static, and the opening state time is T3, resting condition time T4.
Step 4: carrying out three-level debugging, so that stepper motor (5) level-one quiescent time T1 is equal to cover board (10) opening time T3, and walk
It is equal to the total time in period of cover board (10) into the total time in period of motor (5).
