An intelligent fruit size screening device according to claim 1, wherein a fruit collecting box (117) communicated with the discharge hole is arranged at the discharge hole, the bottom surface of the fruit collecting box is obliquely arranged, and a fruit outlet (118) is arranged at the lowest position of the bottom surface of the fruit collecting box.

6. The intelligent fruit size screening device according to claim 1, wherein baffles (119) are arranged on the left side and the right side of the feeding hole, and a plurality of rubber balls (120) are uniformly distributed on the inner side of each baffle.

7. A control method of an intelligent fruit size screening apparatus for an intelligent fruit size screening apparatus according to claim 1, comprising the steps of:

the fruit conveying mechanism conveys fruits from a feeding hole of the cylinder, a spiral screening device in the cylinder rotates to convey the fruits to a discharging hole of the cylinder, the fruits sequentially pass through each screening area, when the fruits pass through arc fruit dropping holes of the screening areas, the fruits smaller than the current arc fruit dropping holes fall into a fruit guide sleeve below the arc fruit dropping holes, the fruits are guided to fall into a corresponding collecting mechanism through the fruit guide sleeve, and finally the fruits which do not fall into the fruit guide sleeve roll out from the discharging hole of the cylinder and fall into the corresponding collecting mechanism;

in the fruit conveying process, a stirring mechanism in the fruit guide cylinder sleeve works to stir fruits in a corresponding screening area, and a controller calculates the time when the swinging head stretches into the cylinder to stir the fruits according to the rotating speed of the spiral blade and the pitch of the spiral blade of the spiral screening device, so that the spiral blade and the swinging head are prevented from interfering with each other.
