During the actual agricultural product screening process, agricultural products of different types and weights have different elastic force requirements. By adjusting the telescopic length of the controllable telescopic rod, the elastic force of the rubber sheet can be changed. For example, for lighter agricultural products, the controllable telescopic rod can be shortened to reduce the elastic force of the rubber sheet and prevent the agricultural products from bouncing too much due to excessive elastic force; for heavier agricultural products, the controllable telescopic rod can be extended to enhance the elastic force of the rubber sheet and ensure that they can be smoothly bounced up for subsequent detection. This adjustable design improves the adaptability of the equipment to agricultural products of different weights, broadens the application range of the equipment, and enhances the versatility and practicality of the equipment in agricultural product screening work.

The plurality of circular openings with different sizes can perform preliminary screening according to the size of the agricultural products. Agricultural products of different sizes fall into the inner cavities of different sorting and transporting cylinders 11. The driving connection ensures that the plurality of sorting and transporting cylinders 11 can operate synchronously, improving the efficiency and accuracy of size-based screening, and laying a good foundation for subsequent further screening.

[0030] Working principle: First step, the adapted agricultural products are sequentially conveyed to the feeding conveyor rack 13 one by one through the conveyor belt, and the second driving motor 133 drives a plurality of feeding rollers 132 to rotate to convey the agricultural products to the sorting and transporting cylinder 11. Since a plurality of circular openings with different sizes are provided on the plurality of sorting and transporting cylinders 11, agricultural products of different sizes fall into the inner cavity of the sorting and transporting cylinder 11 through the circular openings with different sizes and enter the sorting output pipe 14 communicated therewith; Second step, a part of the defective agricultural products are output through the output pipeline 142 and enter different collection buckets 143 for classified collection; another part of the qualified agricultural products sequentially enter the screening device 2 through the transmission pipeline 141, and the agricultural products sequentially fall onto the elastic component 21; at this time, the elasticity of the rubber sheet 214 bounces the agricultural products up; It should be noted that personnel can adjust the elasticity of the rubber sheet 214 by controlling the telescopic movement of the controllable telescopic rod 212 to meet the screening requirements of different agricultural products; Third step, start the photoelectric sensor 4. The bounced agricultural products touch multiple groups or a single group of light rays emitted by the photoelectric sensor 4 during the jumping process. Since the heights of the multiple groups of light rays are different and the bounced heights of the agricultural products are different, the number of light ray groups touched is different. The controller 243 judges therefrom to drive the electric telescopic rod 242 to push or pull the sponge block 23 to incline to one side; Finally, the agricultural products that fall on the top of the sponge block 23 slide down the inclined surface of the sponge block 23 onto the blanking plate 3, and the final screening and separation of the materials are achieved to ensure that defective agricultural products with internal deterioration and hollowness are screened out from the finally selected agricultural products; Moreover, the device has a simple structure and low production cost, and has good economic benefit value.
