However, the centrifugal fan can only blow away the impurities on the surface of the corn kernels, and it is difficult for the centrifugal fan to blow off impurities such as snow, corn whiskers or leaves submerged in the corn kernels, and this separation method can only blow off impurities on the sieve plate. The impurities near the air outlet of the centrifugal fan are blown away, but the impurities in other parts of the sieve plate are difficult to be blown away, which leads to a high impurity rate in corn
In addition, the corn coating, velvet, dust, etc. entrained by the threshed corn kernels can easily block the sieve plate, resulting in wear and tear of the sieve plate.
In response to this situation, there is currently a way to increase the wind speed of the fan to enhance the cleaning effect, but the cleaning effect is still not ideal, and even cause corn kernels to be blown away, causing unnecessary losses

Abstract
The invention provides a light impurity removing device. The light impurity removing device is arranged in corn threshing equipment which comprises a threshing device which is used for threshing corn cobs and discharging threshed objects containing corn seeds and a cleaning sieve device which is used for cleaning the corn seeds. The light impurity removing device is characterized by comprising a flow distribution part and a part for removing impurities by suction; the flow distribution part is positioned below the threshing device and above the cleaning sieve device, and is used for distributing flow of the discharged threshed objects so as to form a plurality of strands of distributed objects; and the part for removing the impurities by suction is used for correspondingly removing the light impurities in the various distributed objects in the suction manner so as to obtain objects without impurities.
Description
technical field [0001] The invention specifically relates to a light impurity removal device and corn threshing equipment comprising the light impurity removal device. Background technique [0002] Corn is one of the widely distributed crops in my country. With the development of modern agriculture, the planting area of corn is increasing. In order to thresh corn cobs, corn threshing equipment is generally used to quickly thresh corn cobs, so that corn Threshing equipment plays an increasingly important role in corn production. [0003] The corn threshing equipment can separate the corn cobs into corn kernels and cob cores, and then remove the impurities in the threshed corn kernels through the cleaning screen and fan, so as to obtain corn kernels with a high cleaning rate. [0004] In the prior art, a centrifugal fan is used to blow air on one side of the cleaning screen, thereby separating the threshed corn kernels from impurities. However, the centrifugal fan can only ...
