Description
技术领域technical field
本发明涉及农用机械设备领域,具体为一种农用谷物三级筛选装置。The invention relates to the field of agricultural machinery and equipment, in particular to a three-stage screening device for agricultural grains.
背景技术Background technique
目前粮食收获后,在粮食中往往会掺入石子、沙粒等杂质,影响粮食的整体质量。因此通常利用粮食筛选机对粮食进行清理,分离原料中的石子、沙粒等大的杂质。然而现有的滚筒式粮食筛选机在使用过程中,由于筛筒角度多为固定,不可根据不同的物料、不同的清理要求进行调整,造成筛选效果不理想。混入粮食粒中的瘪谷、鼓皮、麦穗须和裹进成品流中的尘土等轻质无法有效分离。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.
此外,现有滚筒式粮食筛选机由于粮食中杂质多,在筛选过程中会出现大量的粉尘,影响操作人员的身体健康。且在农民出售过程粮食中,粮食颗粒的筛选成为一个重要的加工步骤。现有的粮食筛选振动清理筛大都只具有一级的分级筛选功能,物料分级度低,有时采用多台设备串联筛分,以达到多粒度分级,极大的浪费了空间资源,提高了成本。不能够多级高效完成粮食的分级筛选;现有的振动清理筛大都不能够高效除去筛选过程中产生的粉尘,对环境和操作人员造成较大危害。若采用人工分离,不仅使农民的工作量加大,且操作速度慢、工作效率低、费时费力且质量不稳定。In addition, due to the many impurities in the grain in the existing drum type grain screening machine, a large amount of dust will appear during the screening process, which will affect the health of the operators. And in the process of farmers selling grain, the screening of grain particles has become an important processing step. Most of the existing grain screening vibrating cleaning sieves only have the first-level classification and screening function, and the material classification degree is low. Sometimes multiple devices are used for series screening to achieve multi-grain size classification, which greatly wastes space resources and increases costs. Grain grading and screening cannot be efficiently completed in multiple stages; most of the existing vibrating cleaning sieves cannot efficiently remove the dust generated during the screening process, causing great harm to the environment and operators. If manual separation is adopted, not only the workload of farmers will be increased, but also the operation speed will be slow, the work efficiency will be low, time-consuming and laborious, and the quality will be unstable.
