[0022] The control box 700 is arranged on the upper end of the mounting plate 100, and has a battery and a controller for the sampling device. It can be understood that the battery in the control box 700 can provide power for the plurality of electric drive units of the sampling device, and the controller can be used to control the operation of each sampling tube 200, so that the sampling operation is more convenient and efficient.
[0023] In the embodiment, the bottoms of the sampling tubes 200 of different lengths are respectively arranged in the sampling layers in the container, so that the slurry in different layers can be sampled when needed.
[0024] The air extraction pipeline 400 includes an air extraction pipe 410 connected to the air chamber 300 at one end and connected to a negative pressure air source through an external pipeline at the other end, and an electromagnetic valve 420 arranged on the air extraction pipe 410. It can be understood that the air extraction pipe 410 is connected to an air extraction pump, a negative pressure air tank, etc. through an external pipeline, and the electromagnetic valve 420 and the air extraction pipe 410 can be closed when not needed. The air exhaust pipeline 500 includes an air exhaust pipe 510 connected to the air chamber 300 at the upper end and matched with the air pipe plug 620 at the lower end, and an electromagnetic valve 520 arranged on the air exhaust pipe 510.
