Sieving and impurity removing equipment for wheat seeds and using method thereof

Abstract

The invention relates to the technical field of wheat seed treatment, in particular to sieving and impurity removing equipment for wheat seeds and a using method thereof. The equipment comprises a bottom frame, a feeding assembly and a screening assembly, the feeding assembly and the screening assembly are both located above the bottom frame, and the screening assembly is located on one side of the feeding assembly. The screening assembly comprises a screening box, a cover plate and a plurality of second connecting bases, the cover plate is located above the screening box, the plurality of second connecting bases are located on the two sides of the screening box correspondingly, a first connecting base is arranged at the bottom of the screening box, two vibration motors are installed on the first connecting base, and a first discharging opening and a second discharging opening are formed in the end, away from the feeding assembly, of the screening box. After the wheat seeds on a screen are separated from impurities, the wheat seeds flow out from the first discharging opening, the impurities fall off from the screen and flow out from the second discharging opening, sieving and impurity removing of the wheat seeds are completed, thus the wheat seeds and the impurities are separated thoroughly, and separation thoroughness of the wheat seeds and the impurities is ensured.

Description

technical field [0001] The invention relates to the technical field of wheat seed treatment, in particular to a screening and impurity removal device for wheat seeds and a use method thereof. Background technique [0002] Wheat is the general name of Triticum, which is a grass plant. Wheat is one of the three major grains, almost all of which are used for food, and only about one-sixth is used as feed. It is a cereal crop widely planted around the world. Wheat Caryopsis is one of the staple foods of human beings. After being ground into flour, it can be used to make bread, steamed buns, biscuits, noodles and other foods. After fermentation, it can be made into beer, alcohol, liquor (such as vodka), or biomass fuel. Wheat is widely used It determines the importance of wheat seeds, and the removal of impurities in wheat seeds is an unavoidable topic, so the equipment for screening and removing impurities of wheat seeds is very necessary.

Problems solved by technology

[0003] The Chinese patent with application number 201911009309.6 discloses a wheat seed sorting machine. A wheat seed sorting machine includes a frame with a seed inlet above the frame and a seed outlet below the frame. And be provided with the first screen cloth and the second screen cloth below, the first screen cloth and the second screen cloth are all obliquely arranged, and the low end of the first screen cloth faces the high end of the second screen cloth, and the lower side of the first screen cloth is A vibrating motor is installed, the vibrating motor is connected with a cam, and the two sides of the first screen are connected with springs. When the cam rotates, it drives the screen vibrating machine. Through two-stage cleaning, the impurities on the wheat surface can be fully removed and cleaned, which is convenient and fast And high efficiency, no manual work is required in the whole process, only the impurities after cleaning can be removed, and high-quality wheat can be produced directly from the wheat export, which greatly saves manpower and material resources, and the efficiency is high. This patent exists after the wheat seeds are separated from the impurities. Defects that require removal of impurities after cleaning

[0004] Yet there is very big defective in the sieving and impurity removal equipment of present wheat seed, and the sieving and impurity removal equipment of present wheat seed, can't replace sieve, and the adaptability of equipment is low; For miscellaneous equipment, the cover plate and the screen box cannot be separated flexibly. When the equipment fails, it cannot be disassembled for maintenance, which makes the maintenance time too long and affects the use of the equipment; Before removing impurities, wheat seeds cannot be preliminarily separated from impurities, resulting in incomplete screening
