Parasitic bran-wheat separating device

Abstract

The invention aims to provide a parasitic bran-wheat separating device which is parasitic on a bran outlet of a combined harvester and fixed to a machine body of the combined harvester by using a fixing frame to carry out secondary separation so as to achieve the effect of net harvesting of wheat grains and increase income. A cuboid separating device is additionally arranged on the bran outlet ofthe combined harvester and is divided into an upper layer and a lower layer, an air screen is arranged in the middle, a bran inlet and a bran outlet are reserved in two ends of the upper layer, a wheat channel is located in the lower layer, a wheat outlet is reserved in the lower end of the lower layer and is combined with a wheat box, the cuboid separating device sleeves the bran outlet of the combined harvester, an upward inclined elevation angle is about 45 degrees, and the cuboid separating device and the wheat box are fixed to the machine body of the combined harvester through the fixingframe. Obviously, the combined harvester has a large wind force at the bran outlet, wheat bran can be blown out when the combined harvester ascends, and wheat grains can be separated in the lower-layer wheat channel and flow into the wheat box from the outlet. The parasitic bran-wheat separating device has the advantages of being simple in structure, easy to manufacture, convenient to use and capable of saving energy and increasing income.

Description

Technical field: [0001] The invention belongs to a device on a combine harvester. Background technique: [0002] It is well known that the wheat bran produced by various combine harvesters in the society is blown to one side of the wheat field through the bran outlet under the action of strong wind, but due to poor internal separation, Most of the wheat bran has a higher wheat content, which seriously affects the output and causes unnecessary losses. For this reason, the special invention is as follows. Invention content: [0003] The present invention is to provide a parasitic type that is parasitic on the chaff outlet of the combine harvester, and fixed on the body of the combine harvester with a fixing frame to perform secondary separation to achieve the effect of net harvesting of wheat grains, so as to increase income. Bran wheat separation device. [0004] The technical solution to solve its technical problems is: add a cuboid separation device on the bran outlet o...

Problems solved by technology

[0002] As we all know, the wheat bran produced by various combine harvesters in the society is blown to one side of the wheat field through the bran outlet under the action of strong wind, but due to poor internal separation, Most of the wheat bran contains a high amount of wheat, which seriously affects the yield and causes unnecessary losses. For this reason, the invention is as follows
