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.

The sampling cup 2-8 is a detachable structure.

Compared with the prior art, the sampling device has the advantages of simple structure and higher efficiency, can replace workers to sample, and can ensure that samples extracted each time are not mixed with each other.

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 sampling cup 2-8 is a detachable structure.

After the flexible rake device 1 has stirred the milk in the milk storage tank of the truck, the sampling structure 2 starts to move. The rubber plug 2-4 is initially positioned at the lower end of the piston cylinder 2-5, after the flexible rake-beating device 1 finishes working, the push rod motor 2-2 contracts the push rod to drive the rubber plug connector 2-3 and the rubber plug 2-4 to move upwards to reduce the pressure in the piston cylinder 2-5, the piston cylinder 2-5 is in a communicated state with the sampling cup 2-8 through the hose 2-6, and therefore milk is sucked into the sampling cup 2-8. The bottom port of the sampling cup 2-8 is provided with a one-way liquid guide film 2-10 which can prevent milk from flowing out. After sampling is finished, the sampling cup 2-8 leaves the milk storage tank along with the flexible harrowing device 1, a worker takes down the sampling cup 2-8 and reinstalls the clean sampling cup 2-8, and therefore samples extracted at each time can not be mixed with each other.
