Maize thresher and maize threshing method

Abstract

The invention discloses a maize thresher. The maize thresher comprises a machine frame, a motor, a threshing fluted disc (1), a centering sleeve (2), a push rod (3), a helical wheel (4) and a hopper (5). The centering sleeve is arranged between the threshing fluted disc and the push rod. The push rod is arranged on a sliding table driven by the helical wheel. The motor drives the threshing fluted disc and the helical wheel to rotate respectively. A maize cob clamping mechanism is arranged at the front end of the push rod. The threshing fluted disc, the centering sleeve and the push rod are coaxially aligned. An outlet of the hopper is aligned to a zone between the threshing fluted disc and a locating sleeve. According to a maize threshing method disclosed by the invention, maize cobs are pushed into the rotating threshing fluted discs by passing through the centering sleeve by the push rod, maize seeds are separated from the maize cobs by a tangential force generated between the teeth of the threshing fluted disc and the maize seeds, the maize is threshed completely in a rotary extruding way, and the maize seeds and the threshed cobs are intact. According to the invention, the separated maize seeds are clean and free of residues, the maize cobs are intact and easy to collect, and the maize thresher is simple in structure, small in threshing power, energy-saving and environment friendly, and suitable for families and enterprises.

Description

technical field [0001] The invention relates to a corn threshing machine and a corn threshing method thereof, which is a threshing method in which corn grains are separated from the corn cob along the circumferential tangential direction of the corn cob. The corn kernels are clean and the cobs are intact, suitable for home or business use. Background technique [0002] Corn is one of the three major grain varieties in China. The annual area of ​​corn planted in my country has reached 30 million hectares, mainly distributed in the main corn producing areas of Northeast and North China and parts of Southwest and Northwest China. Every year after the autumn harvest, people have to thresh the corn. At present, there are two main methods of corn threshing: motor threshing and manual threshing. [0003] The common motorized threshing methods are: directly pour the corn cobs into the drum to break them, and then use wind to clean them; or use the nail teeth arranged in a helical...
