an electric push rod (81) mounted inside the sorting chute (8);
and the sealing plug (82) is connected to the output end of the electric push rod (81), and the sealing plug (82) and the size of the perforation (71) are matched with each other.
4. A rice production line pest egg removal device according to claim 1, wherein the recovery processing tank (10) further includes:
a stirring shaft (101) rotatably installed inside the recovery processing box (10);
a stirring motor (102) connected to the upper end of the stirring shaft (101);
a microwave generator (103) mounted on the inner side surface of the recovery processing box (10);
a recovery hopper (104) connected to the lower end of the recovery processing tank (10);
a valve (105) mounted inside the recovery hopper (104).
5. The pest egg removing method for the rice production line is characterized by comprising the following steps of:
s1, pouring rice into a feeding hopper (1), and enabling the rice to enter a magnetic separation mechanism (2) through the feeding hopper (1) to be screened, wherein a magnetic roller (23) adsorbs iron-containing impurities in the rice, so that influence of the iron-containing impurities on egg-containing rice pest egg sorting effects is reduced;
s2, enabling the rice to enter the collecting hopper (4), and vibrating the feeding screen plate (5) to vibrate at high frequency, so that the rice coming out of the collecting hopper (4) is uniformly distributed through vibration and enters the identification mechanism (6);
s3, the rice slides into the second-stage chute (62) from the first-stage chute (61), the rice can only slide down one grain by one grain due to the width limitation of the second-stage chute (62), the rice is irradiated by the electromagnetic wave generator (63) and the reflected wave absorber (64), the main components of the normal rice are starch, the main components of the worm eggs are proteins, the starch and the proteins have obvious differences on the electromagnetic wave absorptivity of specific wavelengths due to the differences of the biochemical characteristics, the reflected waves are obviously different, and the recognition of the egg-containing rice is realized by analyzing the reflected wave intensity;
s4, when normal rice passes through, the controller (9) controls the electric push rod (81) in the sorting chute (8) to maintain the original state, and the normal rice directly slides down from the sorting plate (7) to be packaged; when the worm-egg-containing rice passes through, the controller (9) controls the electric push rod (81) in the sorting chute (8) to shrink, so that the perforation (71) is opened, and the worm-egg-containing rice falls into the recovery processing box (10) from the sorting chute (8);
s5, the recycling treatment box (10) carries out centralized insecticidal treatment on the rice containing the ova, and the treated rice can normally enter a circulation link after being inspected to be qualified.
