Problems solved by technology

[0003] Corn needs to be screened before sowing, and the full corn is screened out as seeds. However, most of the existing corn seed screening devices use manual shaking sieves to screen them, which is not only time-consuming and laborious, but also the screening effect is not very good. The screening speed is slow and the work efficiency is low

Abstract

The invention provides a corn seed screening machine. The multiple stages of screens are arranged on a base and stacked in the vertical direction, the sizes of screen holes of the multiple stages of the screens are gradually decreased from top to bottom, a discharging opening is formed in one side of each stage of the screen, so that screening of corn seeds of various sizes is achieved, waste trays are arranged at the bottoms of the multiple stages of the screens, impurities and the unusable corn seeds can be screened, so that the influence on corn planting is avoided, meanwhile, a vibration assembly connected with the multiple stages of the screens is arranged on the base to drive the multiple stages of the screens to vibrate, so that the corn seeds are automatically screened, the screening efficiency is improved, and the labor cost is saved. A scraper is arranged on each screen, the scrapers move back and forth relative to the screens in one direction so that the corn seeds in the screens can be evenly laid on the screens, and the situation that the screening efficiency and effect are reduced due to accumulation is avoided.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a corn seed screening machine. Background technique [0002] Corn is an annual monoecious cross-pollinated plant with tall plants and strong stems. It is an important food crop and feed crop. It is also the crop with the highest total output in the world. Its planting area and total output are second only to rice and wheat. Corn has always been Both are known as longevity foods, rich in protein, fat, vitamins, trace elements, cellulose, etc., and have great potential for developing foods with high nutrition and high biological functions. [0003] Corn needs to be screened before sowing, and the full corn is screened out as seeds. However, most of the existing corn seed screening devices use manual shaking sieves to screen them, which is not only time-consuming and laborious, but also the screening effect is not very good. The screening speed is slow and the work e...
