Background technique

Maize 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 known as a longevity food, rich in protein, fat, vitamins, trace elements, cellulose, etc., and has great potential for developing high-nutrition and high-biological function foods.

When corn is harvested, it is inevitable to be mixed with dust, corn leaves, corn silk, corn cobs, stones and other sundries. These sundries have brought a lot of troubles to corn seed processing enterprises. In order to improve the quality of corn seeds during the processing of corn seeds, it is necessary to screen out the sundries in the corn seeds. The vibrating screens commonly used in modern times are mostly one-time screening, which is inefficient and poor in screening quality.

A feeding hopper is arranged above the left end of the vibrating cabinet.

The vibration cabinet is in the shape of an inverted cone.

The bottom surface of the vibration cabinet is inclined downward from left to right, and the right end of the bottom surface of the vibration cabinet is provided with a sundry outlet.

The inclination angles of the first screen and the second screen are the same, and the installation inclination angle of the vibrating motor is the same as that of the first screen and the second screen.

The first screen and the second screen are fixed by bolts.

The outlet of the debris tank is backward, and the outlet of the seed collection tank is forward.

The first screen is a coarse filter; the second screen is a fine filter.

Compared with the prior art, the utility model has the following beneficial effects: a first sieve and a second sieve are arranged in the vibrating cabinet, and the corn seeds can be screened by the first sieve to remove corncobs, corn leaves, straw, etc. The sundries larger than corn seeds, after that, the corn seeds fall on the second screen, and the sundries smaller than the corn seeds, such as stones and small clods, fall to the bottom of the vibrating cabinet, and the corn seeds pass through the seed collection tank and collection funnel, and are transported through the The exhaust fan on the pipe removes light impurities such as dust and corn whiskers. The utility model ensures the screening quality through classification and screening; the installation inclination angle of the vibration motor is the same as that of the first screen and the second screen, ensuring that the first The screen and the second screen have the largest amplitude to ensure vibration efficiency and improve screening efficiency.
