The front and rear sides of the conveying mechanism 2 are movably connected to the box body 1 with connection holes opened at both the front and rear ends. The front end of the conveying mechanism 2 is fixedly connected to the output shaft of a first motor 11. By setting the drying and feeding mechanism 8, a uniform feeding process of agricultural and sideline products can be realized, so that the agricultural and sideline products can be uniformly fed into the interior of the box body 1, and a preliminary drying effect can be achieved on the agricultural and sideline products during the feeding process. By the rotation of the output shaft of the first sprocket 9, under the action of the set vibration screening mechanism 7, a screening effect can be achieved on the agricultural and sideline products entering the interior of the box body 1, effectively removing smaller impurities in the agricultural and sideline products. Thus, the device can not only achieve a drying effect on the agricultural and sideline products, but also achieve a impurity removal effect on the agricultural and sideline products during the drying process. By the rotation of the output shaft of the first motor 11, under the action of the set conveying mechanism 2, the dried and impurity-removed agricultural and sideline products inside the box body 1 can be discharged from the interior of the box body 1, making the collection process of the agricultural and sideline products after drying more convenient.

By arranging the collection box 6, the impurities screened by the vibration screening mechanism 7 can be conveniently collected for subsequent centralized treatment. By arranging the material guiding frame 3, it can play a guiding role for the agricultural and sideline products after screening and impurity removal, so that the agricultural and sideline products can smoothly fall onto the conveying mechanism 2. By arranging the two drying plates 4, it can play a role of drying the agricultural and sideline products passing through the material guiding frame 3 and falling onto the conveying mechanism 2 again.
