The secondary swing drives the incomplete gear 24 to swing back and forth through the reciprocating swing of the swing shaft 21 and the incomplete gear
The gear 24 is reciprocated and the meshing relationship between the incomplete gear 24 and the second rack plate 26 is driven
The second light shielding sleeve 13 reciprocates and is jointed with the light shielding sleeve 13 shown in the figures 1, 4 and 5
It is shown that each time the shutter I10 and the shutter II 11 are closed, the shade sleeve II 13 and the shade sleeve I12 are also closed
Form a closed state, so that the liquid egg flowing between the first baffle plate 10 and the second baffle plate 11 can be in a closed state
In the state, the ultraviolet light emitted by the light source 1 conveniently penetrates through the liquid egg and is collected by the optical fiber probe 2, thereby avoiding the situation that
The influence of external light;
at the same time, the second shading sleeve 13 moves back and forth and is combined with the figure 1, so that the second shading sleeve 13 at each time
When the egg is moved to the state shown in fig. 1, the operator can observe the flowing condition of the liquid egg in the pipeline 3 at any time.
