Detailed Description
The invention will be further described with reference to the accompanying drawings in which:
as shown in fig. 1-11, the sampling structure suitable for the flexible rake-beating device comprises a flexible rake-beating device 1 and a sampling structure 2; the sampling structure 2 is arranged inside the flexible rake-beating device 1; the sampling structure 2 comprises a motor fixing frame 2-1, a push rod motor 2-2, a rubber plug connector 2-3, a rubber plug 2-4, a piston cylinder 2-5, a hose 2-6, a bottom cover 2-7, a sampling cup 2-8, a bolt 2-9 and a one-way liquid guide film 2-10.
The motor fixing frame 2-1 is arranged in the flexible rake beating device 1; the push rod motor 2-2 is connected to the motor fixing frame 2-1 through a bolt 2-9, and the rubber plug connector 2-3 is connected with a push rod of the push rod motor 2-2; the rubber plug 2-4 is sleeved at the bottom end of the rubber plug connector 2-3, and the rubber plug 2-4 can move in the piston cylinder 2-5 along with the rubber plug connector 2-3; the piston cylinders 2-5 are arranged on the flexible rake beating device 1; the upper end port of the hose 2-6 is installed on the lower end port of the piston cylinder 2-5 through threads; the lower port of the hose 2-6 is mounted on the upper port of the bottom cover 2-7 through threads; the sampling cup 2-8 is mounted to the bottom cover 2-7 through threads; sealing the lower port of the sampling cup 2-8 by using a single-guide liquid film 2-10; the bottom cover 2-7 is connected to the lower end of the flexible shell of the flexible rake-beating device 1.
