Abstract

The invention relates to a spiral belt piece type multi-gas field drum screen grain cleaning machine which comprises a hollow cylinder roller, wherein the two ends of which are respectively provided with a hollow shaft; the cylinder roller and the hollow shafts have the same axle center; one end of the cylinder roller is a feed end, and the other end thereof is an airflow inlet end; internal spiral belt pieces are continuously arranged along the inner circumference and the axial direction of the cylinder roller; a roller body between the ends of the internal spiral belt pieces and the port of the airflow inlet end of the cylinder roller is provided with a first-stage cylinder screen, and the outer circumference of the first-stage cylinder screen is then sheathed with a second-stage cylinder screen which is coaxial with the first-stage cylinder and has a certain radial space with the first-stage cylinder; and the feed end of the cylinder roller is provided with a feed groove which does not operate along with the roller and is provided with a discharge hole positioned inside the roller. The machine has the characteristics of good cleaning effect, high working efficiency and energy conservation, and is simple in structure and light in weight.

Description

technical field [0001] The technology of the invention relates to a device for screening and separating the harvested, threshed and separated grain mixture to obtain clean grains, that is, a grain cleaning device. Background technique [0002] Mature rice generally needs to be harvested, threshed (diameter, seed separation) and screened before being stored in the warehouse for future use. After being taken off by the threshing device and separated, the extrudate is mixed with inclusions such as broken stems, chaff and dust, which are called grain mixtures. The function of the grain cleaning device is to separate the useful grains in the grain mixture, and discharge other debris out of the machine to obtain clean rice grains. This device that separates grain kernels from the grain mixture is called a grain cleaner. [0003] Most of the grain cleaning devices commonly used in the market now use the so-called wind and sieve compound cleaning machine, which combines plane scre...
