Grain impurity removing machine

Abstract

The invention discloses a grain impurity removing machine. The grain impurity removing machine comprises a shell, moving rolling wheels fixedly connected with the shell and a fan installed on the leftside of the shell. A feeding port is formed in the top of the shell, a hinge is arranged on the right side of the feeding port and located on the shell and connected with a baffle, an arc-shaped flowguiding plate is arranged on the right end surface of the shell, a separating tank is arranged at the bottom of the shell, and a discharging port is formed in the lower bottom surface of the separating tank. Due to the fact that the grain impurity removing machine is provided with the shell and the feeding port, grain enters the interior of the shell through the feeding port, under the action ofthe fan, the entered grain is rapidly blown to the flow guiding plate, the flow guiding plate drives the grain to move towards the upper part of the shell, in the moving process, grain husks or strawamong the grain are blown out of the shell, the baffle can effectively prevent the grain husks or the straw from entering the interior of the shell again, and the separating tank can separate the grain after being subjected to impurity removing to the position of the discharging port; and the grain impurity removing machine is simple in structure, the use is convenient, grain impurity removing iscomplete, and the grain impurity removing machine is worth popularizing.

Description

Technical field [0001] The invention relates to the technical field of grain purification, in particular to a grain cleaner. Background technique [0002] During the crop harvesting season, farmers need to screen the dried grains to remove the dust, rice husks, straws, etc. that are mixed in the grains, and then store the grains without impurities in the granary. Go in. In the traditional cleaning process, the farmers raise the exhaust fan, and then the farmers bend over to put the dried grain into the bucket, straighten up and raise the bucket so that the bucket is higher than the exhaust fan, and then put the bucket up. The grains in the bucket fall down. When these grains are blown by the exhaust fan, the impurities mixed in the grains can be blown away, thereby separating the grains from the impurities. However, this traditional impurity removal device makes the labor intensity of farmers very heavy; moreover, farmers can only screen grains one by one, instead of continuous...

Problems solved by technology

However, this traditional impurity removal device makes the labor intensity of the farmers very high; moreover, the farmers can only screen the grains bucket by bucket, and cannot continuously screen, so the screening efficiency is also very low. Some impurity removal devices have a short time for grain removal, causing some impurities to enter the nylon bag without being removed in time, resulting in the need for secondary screening of some grains. For example, the Chinese invention patent with the application number CN201510753506.4. The feed port is connected to the feed port, and the grain will enter the discharge port without stopping during the impurity removal process, so it is difficult to ensure that the grain is completely removed
