Processing equipment for screening rice grains

Abstract

The invention relates to processing equipment for screening rice grains. The processing equipment comprises a main body, a sieve plate, a vibrator, a feeding pipe, a discharging pipe and two supporting blocks, and further comprises a winnowing mechanism and an adjusting mechanism, wherein the adjusting mechanism comprises two connecting assemblies and two adjusting assemblies, and each adjusting assembly comprises an adjusting plate and a hinge rod; each connecting assembly comprises a support, a connecting rod and a plurality of elastic ropes; the winnowing mechanism comprises a winnowing assembly body, a fixing box, an exhaust pipe and a compression assembly; and the winnowing assembly body comprises a sucking pump, an air inlet pipe, an air outlet pipe, a connecting box and a pluralityof nozzles, and each supporting unit comprises a supporting plate and a first spring. According to the processing equipment for screening rice grains, through the adjusting mechanism, the function ofadjusting the feeding quantity of the grains in real time is achieved, the situation that the grains are excessively fed and accumulated above the sieve plate is avoided, so that influence on the screening work is avoided, the winnowing function is achieved through the winnowing mechanism, fine chippings mixed in the grains can be removed, and the screening quality is improved.

Description

technical field [0001] The invention relates to the field of rice harvesting and processing equipment, in particular to a processing equipment for rice grain screening. Background technique [0002] Grain screening machine refers to the equipment that can screen and process the grain, which can remove most of the detritus and impurities in the grain. [0003] When the existing grain screening machine works, the grains are only screened through the vibrating sieve plate, and the screening method is relatively simple, so that some fine straw debris will pass through the sieve plate together with the grains, thereby reducing the screening capacity. quality, which reduces the reliability of the existing grain screening machine, not only that, when the existing grain screening machine is working, if too many grains are added, the grains will be piled up on the top of the sieve plate, Thereby the screening work is affected, the efficiency of screening is reduced, thereby reducing...
