[0050] Secondly, the livestock is driven to walk through the walking triangular plate 8 to the top of the treading plate 3, so that the treading plate 3 is subjected to a downward force when the livestock treads on the top of the treading plate 3, and the extrusion rod 6 is driven to press the pressure sensor 7, so that the force of the treading on the top of the treading plate 3 is transmitted to the user in real time, and the user can know the weight of the livestock in time.

[0051] Thirdly, the livestock is attracted to lick the absorbing cotton layer 25 by using the licking brick 26, so that the saliva of the livestock is absorbed by the columnar inflatable air bag 24, and then the absorbing cotton layer 25 is moved into the flow guide pipe 15 by using the traction assembly, the exhaust pump 28 is further driven to work to deliver gas into the columnar inflatable air bag 24 to inflate and extrude the saliva absorbed in the absorbing cotton layer 25, and then the saliva enters the flow guide pipe 15 to be received by the sampling assembly, and the whole process does not need manual operation of the staff, and the efficiency is high.
