A push-pull grading and screening device for jujubes and sour jujubes

Abstract

This utility model relates to the technical field of grading and screening devices, specifically a push-pull grading and screening device for jujubes and sour jujubes. It includes several iron pillars with connecting pillars between them. Support seats are provided on two pairs of iron pillars, and a first screening basket is movably connected to each support seat. A second screening basket is movably connected to the first screening basket, and a third screening basket is movably connected to the second screening basket. A jujube-receiving basket is located below the first screening basket. This utility model, through the coordinated use of the first, second, and third screening baskets and the jujube-receiving basket, can classify jujubes into four grades according to size, achieving refined grading. The utility model also features a handle with a rubber pad on the handle. The surface of the rubber pad has anti-slip particles, increasing friction and making it more comfortable to grip, thus improving screening efficiency. This utility model is manually push-pull, requiring no oil or electricity, saving energy and reducing costs.
