Description

Technical Field

[0001] The utility model relates to the technical field of grain cleaning during silo filling, and specifically relates to a grain cleaning device for port grain silo filling. Background Art

[0002] After harvesting, grains need to be dried in time to evaporate the free water in the grain particles, so as to reduce the metabolism of the seeds and inhibit the chemical reactions of life activities in the cells, so that the grains can be stored without germinating. Currently, the drying sites in rural areas are either cement floors or sun-dried and compacted mud floors. Inevitably, various impurities such as dust, broken cobs, leaves, chaff, shriveled grains, bad seeds, and stones are mixed into the grain particles during the harvesting process, and these impurities need to be removed for grain storage.

[0003] After drying on the sun-dried and compacted mud floor and during collection, the small soil blocks separated from the mud floor will be mixed into the grains, which are not easy to clean. The small soil blocks will contaminate and dirty the grains, affecting the appearance of the grains, and then affecting the grain storage in the warehouse, which is not conducive to grain preservation. For this reason, we propose a grain cleaning device for port grain silo filling. Content of the Utility Model

[0014] Compared with the prior art, the utility model provides a port grain bin entry impurity removal device, which has the following beneficial effects:

[0015] 1. The port grain bin entry impurity removal device uses two impurity removal devices to remove impurities from the grain entering the bin, namely the fan filtering device and the filter screen filtering device. The cooperation of the two effectively removes various impurities in the grain. The fan filtering device can first remove and isolate impurities with lighter quality, such as dust, leaves, chaff, etc., and the subsequent filter screen filtering device can remove larger particle impurities. The combined action of the two makes the grain impurity removal clean and the storage safe.

The grain is put into the large opening end of the triangular funnel 3 by external equipment. The grain falls into the interior of the fan impurity removing box 1 at the rectangular pointed end of the triangular funnel 3. At this time, the fan group 7 provided inside the fan impurity removing box 1 starts to blow, blowing the lighter impurities during the falling process to the end away from the fan group 7. And at the end of the interior of the fan impurity removing box 1 away from the fan group 7, there is a dust collector 8 and a small impurity collecting box 12. The small particle impurities are blown by the fan group 7 into the interior of the small impurity collecting box 12, while some easily flying impurities such as dust and lint are sucked by the dust collector 8 into the designated position for centralized treatment. At the end of the interior of the fan impurity removing box 1 away from the triangular funnel 3, there is a slideway 13.
