Suction type impurity and stone removing machine for grains

Abstract

The present invention discloses a suction type impurity and stone removing machine for grains. The suction type impurity and stone removing machine comprises a rack, an upper eccentric mechanism, a flat screen, a fan, a stone remover, a lower eccentric mechanism and a big belt wheel; the upper left portion of the rack is connected with the upper eccentric mechanism; the upper eccentric mechanism is connected with the flat screen; a discharging plate of the flat screen is aligned with a feeding port stretching into the stone remover; the stone remover is erected at the right side of the rack through the lower eccentric mechanism; an upper portion of the stone remover is connected with the suction fan; the suction fan is fixedly connected between vertical rods at the right side of the rack; a rear end of a main shaft of the lower eccentric mechanism is connected with the big belt wheel; the big belt wheel is connected with a motor through a belt; the motor is installed at a lower portion of the rack; a front end of the main shaft of the lower eccentric mechanism is connected with a lower belt wheel connecting an upper belt wheel of the upper eccentric mechanism through a power belt; and a shield covers the upper belt wheel, the power belt and the lower belt wheel and is fixedly connected at the front side of the rack. The suction type impurity and stone removing machine has the beneficial effects that impurities are separated clearly, stone removal efficiency is relatively high, the whole machine is sealed, dust spread is prevented, rubber bearings are adopted for reciprocating swing, and the noise is reduced to be lowest.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery and food processing mechanism, in particular to a grain suction type impurity and stone removal machine. Background technique [0002] The grain of farmers’ friends is harvested by the combine harvester and directly threshed into grain grains. In some areas, the traditional method is still used for harvesting, and then threshed into grain grains through the sun, no matter which method is used. Grain harvesting contains a lot of impurities in the grain. If it is harvested by a harvester, the grain contains a large amount of straw, shrunken shells, grass seeds, etc., which will affect the quality of the grain particles. If the grain is manually harvested and threshed As for the harvested grain, although weeds are artificially removed during the harvesting process, there are no grass seeds, but there are still some straws, a large amount of small stones and dust mixed in the grain part...

If the grain is manually harvested and threshed As for the harvested grain, although weeds are artificially removed during the harvesting process, there are no grass seeds, but there are still some straws, a large amount of small stones and dust mixed in the grain particles, which also affect the grain quality. quality problems
