A plurality of reaction cups 50 are clamped in the screening groove 20 in sequence along the length direction of the screening groove 20, the lifting power mechanism 21 drives the screening groove 20 and the reaction cups 50 therein to be lifted together, and when the screening groove 20 is positioned at a discharging station, the transportation module conveys the reaction cups 50 in the screening groove 20 along the length direction of the screening groove 20.

It will be appreciated that the inner bottom surface of the collecting chamber 10 is inclined and the sieve opening is located at the lowermost end of the inner bottom surface of the collecting chamber 10, so that the reaction cup 50 in the collecting chamber 10 can actively fill the sieving tank 20 under the action of gravity. Further, the inner bottom surface of the collecting bin 10 includes two inclined surfaces, a screen opening is formed between the bottom end edges of the two inclined surfaces, that is, the bottom surface of the collecting bin 10 is V-shaped, and the reaction cups 50 located at both sides of the screen opening can enter the screen opening. When the screening groove 20 is located the pan feeding station, the reaction cups 50 of sieve mouth both sides all move to the sieve mouth, because the horizontal motion direction when the reaction cup 50 of both sides moves to the sieve mouth is opposite, consequently can strengthen the degree of disorder of reaction cup 50 motion in the collecting bin 10, be favorable to more reaction cups 50 to the sieve mouth motion in order to fill screening groove 20.
