Grain Seed Screening Device

Abstract

The invention discloses a grain seed screening device. The device comprises a stirring box, and the two sides of the bottom of the stirring box correspondingly communicates with one end of a first material pipe and one end of a second material pipe; the top of the second material pipe communicates with a hopper, and the hopper is connected with a first motor through a supporting rod; and a first motor is located at one end, far away from the stirring box, of the second material pipe. The device is simple in structure, seeds to be screened are poured into the hopper, under the gravity action, the seeds fall into the second material pipe, the first motor drives spiral blades and a stirring rod to rotate through the second rotating shaft, and the spiral blades continuously bring the seeds into the stirring box; and the stirring rod is used for continuously stirring the seeds in the stirring box, due to the fact that the stirring box has certain depth of water, under the action of buoyancy, the dried seeds or the rice husks can float up and float on the water surface, finally, the floating objects are scraped out by a scraping brush, the floating objects rotate continuously along withspiral blades, the grain seeds are extruded from the discharging pipe under the action of the pressure, so that the screening is completed, and the device is simple and efficient.

Description

technical field [0001] The invention relates to the technical field of screening, in particular to a grain seed screening device. Background technique [0002] Cereals cover a wide range, including rice, wheat, millet, soybeans, etc. and other miscellaneous grains. Cereals include rice, wheat, millet, soybeans, etc., mainly plant seeds and fruits, and cereals mainly refer to the seeds of gramineous plants. Five grains mainly include rice, wheat, soybeans, etc. and other miscellaneous grains, such as millet, black rice, buckwheat, oats, barley, sorghum, etc. Through processing, grains provide humans with 50% to 80% of heat energy, 40% to 70% of protein, and more than 60% of vitamin B1 for humans. Cereals can vary greatly in nutrient content due to different types, varieties, origins, growth conditions and processing methods; before planting seeds, in order to ensure the germination rate of seeds, they need to be screened. The efficiency of existing screening equipment is l...
