The invention relates to a fruit screening and conveying
production line and a technological process thereof. The fruit screening and conveying
production line comprises a rack, the rack is provided with a cleaning
assembly and a spiral conveying disc, the
diameter of the spiral conveying disc is gradually increased from top to bottom in the height direction, the spiral conveying disc comprises an outer ring plate, a bottom plate and an inner ring plate, and the spiral conveying disc is provided with a feeding port and a discharging port. A plurality of through openings are formed in the bottom plate, the diameters of the through openings are gradually increased from the end close to the feeding port to the end away from the feeding port, a discharging
pipe is fixedly connected to the lower portion of the bottom plate, a first collecting box is connected to the discharging
pipe, a second collecting box is arranged below the discharging port, strip-shaped grooves are formed in the positions, close to the through openings, of the bottom plate, and a shifting
assembly is fixedly connected to the inner ring plate. The shifting
assembly comprises a positioning plate, a first motor and a
cam, and the
cam is matched with the strip-shaped grooves. By arranging the spiral conveying disc and the multiple through openings, fruits are screened in a classified mode according to the sizes of the fruits, and the
