High screening efficiency multifunctional grain screening machine capable of achieving screening of multiple products

Abstract

The invention discloses a high screening efficiency multifunctional grain screening machine capable of achieving screening of multiple products. The multifunctional grain screening machine comprises arack which is internally provided with a motor fixedly, and an output shaft of the motor is fixedly provided with a rotating disk; the upper end of the rotating disk is fixedly provided with a firstrotating shaft connected with a connecting rod rotatably, and the other end of the connecting rod is connected with a second rotating shaft rotatably; the second rotating shaft is fixed to a connecting block of which one end is fixedly provided with a grain screening mechanism, and the upper end of the rack is fixedly provided with mounting bases which are provided with first sliding rails; the upper end of each mounting base is fixedly provided with a mounting rack, and a storage hopper is fixed between the mounting racks; and the lower end of the storage hopper communicates with a discharging channel, and a fan is fixed to the lower ends of the mounting racks, and communicates with the discharging channel. Through the above machine, such lighter impurities as dust and straws in grain, aswell as larger and smaller particle impurities can be eliminated; and the screening quality and the efficiency are high.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a multifunctional grain screening machine capable of screening various products and having high screening efficiency. Background technique [0002] Agricultural machinery refers to various machinery used in crop planting and animal husbandry production, as well as in the primary processing and handling of agricultural and animal products. Agricultural machinery includes agricultural power machinery, farmland construction machinery, soil tillage machinery, planting and fertilization machinery, plant protection machinery, farmland drainage and irrigation machinery, crop harvesting machinery, agricultural product processing machinery, animal husbandry machinery and agricultural transportation machinery, etc. Nowadays, grain is generally harvested mechanically with special machinery, and corn, wheat, soybeans, etc. are put into the grain. The grain harveste...
