Problems solved by technology

Most of the existing vibrating cleaning sieves for grain screening only have the function of one-level grading and screening, and the material grading degree is low. Sometimes multiple devices are used for sieving in series to achieve multi-grain size grading, which greatly wastes space resources and increases costs.
It is not possible to efficiently complete the grading and screeni...

Abstract

The invention discloses a rice crop primary processing device which comprises a screening machine box installed on a rack. The screening machine box is fixed to the upper end of the rack, a feeding opening is formed in the middle portion of the left side of the top end of the screening machine box, and a packing auger feeding mechanism is in butt joint with the feeding opening; a blast pipe is arranged on the right side of the feeding opening and is in butt joint with an external air blower; the screening machine box is internally provided with a thick screening net and a thin screening net from top to bottom in a spaced manner; a first sundry outlet, a grain outlet and a second sundry outlet are formed in the right side of the screening machine box; and a damping base is installed in the middle portion of the bottom end of the rack, a vibrating motor is fixed to the damping base, an eccentric connecting rod assembly is used for connecting the vibrating end of the vibrating motor with the bottom end of a base plate of the screening machine box, an air sucking pipe is arranged on the left side of the screening machine box, the inner end of the air sucking pipe is communicated with the interior of the screening machine box through multiple sucking openings, and the outer end of the air sucking pipe is in butt joint with a cloth bag dusting machine.

Description

technical field [0001] The invention relates to the field of agricultural machinery equipment, in particular to a primary processing device for rice crops. Background technique [0002] At present, after the grain is harvested, impurities such as stones and sand are often mixed into the grain, which affects the overall quality of the grain. Therefore, the grain screening machine is usually used to clean the grain and separate large impurities such as stones and sand grains in the raw materials. However, during the use of the existing drum-type grain screening machine, because the angle of the screen drum is mostly fixed, it cannot be adjusted according to different materials and different cleaning requirements, resulting in unsatisfactory screening effect. The shriveled grains, drum skins, wheat ear silk mixed in the grain grains and the dust wrapped in the finished product flow cannot be effectively separated. [0003] In addition, due to the many impurities in the grain ...
