Transit conveying, impurity removing and sorting system of grains

Abstract

The invention provides a transit conveying, impurity removing and sorting system of grains. The transit conveying, impurity removing and sorting system comprises a feed lifting mechanism, wherein one end of the feed lifting mechanism and ground are contacted to form a feeding end; the other end of the feed lifting mechanism obliquely upwards extends to the upper part of a preliminary screening device; a conveyor belt screening mechanism is arranged at the feeding end of the feed lifting mechanism; a discharge lifting mechanism is arranged below an outlet of the preliminary screening device; one end of the discharge lifting mechanism is arranged on the ground, and the other end of the discharge lifting mechanism obliquely upwards extends to the upper part of a fine screening device; a granary inlet conveyor belt is arranged below a grain outlet of the fine screening device and is connected with a silo; an outlet screening mechanism is arranged at an outlet of the silo; a bagging machine is arranged below the outlet screening mechanism; and a loading and feeding mechanism is arranged at one side of the bagging machine. After the scheme is adopted, the transit conveying, impurity removing and sorting system is high in degree of automation and good in use effect.

Description

technical field [0001] The invention relates to the technical field of grain production, in particular to a grain transfer, impurity removal, and sorting system. Background technique [0002] Harvested grain needs to be removed from frivolous objects such as rice leaves and rice stalks. At present, the grain is mostly pushed flat on the sun-drying field, and then the larger rice leaves and rice stalks are screened while turning with a bamboo rake, and then passed through a windmill. Sieves, sieves and other equipment for screening, and finally into the warehouse, and then manually bagged when selling grain, carried on the car, this method has many procedures and high labor intensity. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a system with high automation and good effect for grain transfer, impurity removal and sorting. [0004] In order to achieve the above object, the technical sol...
