Description
Technical Field
The present invention relates to the field of sorting.
Background
The peanut kernel is also called peanut kernel or peanut kernel, is the seed of peanut, and is in the form of ovoid or blunt circle, and is formed from seed coat, cotyledon and embryo. The color of the seed coat is light brown or light red, and the seed coat is thin and easy to break. The seed skin is provided with two cotyledons which are raw materials for producing edible vegetable oil, and the peanut kernels comprise 40-50% of fatty oil, 20-30% of nitrogen-containing substances, 8-21% of starch, 2-5% of cellulose, 5-8% of water, 2-4% of ash, vitamins and the like. After the seed coat is broken, the cotyledon is easy to come out from the seed coat, and the cotyledon is in a semi-spherical shape (i.e. one surface is a straight surface, and the other surface is a spherical surface). The peanut can be used as seed and processed into non-staple food.
Before peanut grains are used as seeds or processed into crisp peanuts and sugar-coated peanuts, a pile of peanut grains is usually screened once, mixed cotyledons which are separated from seed coats are screened from the pile of peanut grains, and only the peanut grains with complete seed coats and full grains are reserved. The existing method adopts manual bare-handed screening, but the screening efficiency is very low.
Disclosure of Invention
The invention aims to provide a peanut kernel screening device which is used for efficiently screening peanut cotyledons from a peanut kernel stack.
The peanut kernel screening device comprises a conveyor belt, a mixing mechanism, a turn-over mechanism and a separating mechanism, wherein the conveyor belt comprises a horizontal conveying section and an inclined section, the horizontal conveying section is connected with the inclined section, and the mixing mechanism and the turn-over mechanism are both arranged above the horizontal conveying section; the mixing mechanism comprises a mixing tank, a liquid inlet, a mixing blade and a discharge port, the liquid inlet faces the mixing tank, the mixing blade is rotatably connected in the mixing tank, the mixing blade is connected with a first driving device for driving the mixing blade to rotate, and the discharge port faces the horizontal conveying section; the turnover mechanism comprises a scraping plate and a turnover roller, the scraping plate is arranged between the mixing mechanism and the turnover roller, a first gap through which only one peanut granule passes is formed between the scraping plate and the horizontal conveying section, the axis of the turnover roller is horizontal, the turnover roller is cylindrical, the cylindrical surface of the turnover roller is made of elastic materials, a second gap is formed between one side of the turnover roller, close to the horizontal conveying section, and the height of the second gap is 1/3-1/2 of the height of the first gap, and a second driving device for driving the turnover roller to rotate is connected to the turnover roller; a material receiving container is arranged obliquely below the joint of the horizontal conveying section and the inclined section; the separating mechanism comprises a first baffle which is abutted against the inclined section.
The technical principle and the beneficial effects of the scheme are as follows: the peanut kernel stack is poured into the material mixing groove, liquid such as water and vegetable oil is introduced into the material mixing groove through the liquid inlet, the first driving device is started to drive the stirring blade to rotate, the liquid is uniformly covered on the surfaces of the peanut kernels, and the peanut kernels mixed with the liquid are placed on the horizontal conveying section of the conveying belt from the discharge port.
The conveyer belt is conveyed by the mixing mechanism to the turn-over mechanism at a constant speed, and the inclined section is positioned at the tail end of the conveying direction. When the piled peanut kernels on the conveying belt pass through the scraper, the scraper scrapes the peanut kernels on the conveying belt into a peanut kernel layer with the thickness of only one peanut kernel. The straight surface of the cotyledon is attached to the conveyer belt because the surface of the cotyledon is covered with liquid, the straight surface of the cotyledon is in surface contact with the conveyer belt, and the straight surface of the cotyledon is upward and the whole peanut kernel is in point contact or line contact with the conveyer belt. When the peanut kernels move to the turnover roller, the second driving device is started, and the second driving device drives the turnover roller to rotate along the direction opposite to the moving direction of the conveyor belt. When the peanut grains pass through the second gap, the turnover roller applies a turnover force to each peanut grain and the cotyledon, the complete peanut grains roll automatically, the cotyledon with the upward straight surface is turned over to the position with the downward straight surface and then buckled on the conveying belt, and the cotyledon buckled on the conveying belt cannot be turned over by the turnover roller, so that all the cotyledons can be stuck on the horizontal conveying section of the conveying belt by liquid in a manner that the straight surface of the cotyledon is downward.
When the peanut kernels move to the inclined section along with the conveyor belt, the cotyledon continues to move along the conveyor belt under the action of viscous force, and the complete peanut kernels are thrown into the material receiving container under the action of inertia. When the cotyledon moves to the first baffle, the first baffle scrapes the cotyledon off the conveyor belt.
The scheme can accurately screen out the cotyledons in the peanut kernel stack in batches, greatly improves the screening efficiency, and is suitable for large-scale industrial production.
Further, the inclination angle of the inclined section is 45-90 degrees. The inclined section has enough inclination angle to enable the horizontal conveying section to throw out the complete peanut kernels into the material receiving container, so that the complete peanut kernels can be effectively separated from the cotyledon, and meanwhile, the larger the inclination angle is, the larger the space for arranging the material receiving container is.
Further, still include the tensioning roller, the tensioning roller is located the below of horizontal transfer section, the conveyer belt is connected on the tensioning roller, is connected with the telescoping cylinder that promotes the displacement of tensioning roller on the tensioning roller. An inclined section is formed between the tensioning roller and the horizontal conveying section, and when the telescopic cylinder drives the tensioning roller to displace, the inclination angle of the inclined section can be adjusted.
And the turning roll is positioned between the second baffle and the scraper. The cotyledon with the straight surface facing upwards may be stuck on the cylindrical surface of the turnover roller when passing through the second gap, the cotyledon stuck on the turnover roller is scraped off from the turnover roller by the second baffle plate, and the second baffle plate is arranged on one side far away from the scraper plate, so that the cotyledon on the second baffle plate is prevented from falling back to the horizontal conveying section.
Furthermore, strip-shaped stripes are arranged on the turn-over roller and distributed along the length direction of the turn-over roller. The contact area between the peanut kernels and the cotyledons and the turnover roller is reduced by the stripes, so that the viscous force between the turnover roller and the peanut kernels and the cotyledons is reduced, the probability that the peanut kernels and the cotyledons are adhered to the turnover roller is reduced, and the turnover effect of the cotyledons is better.
Furthermore, a cushion pad is paved on the inner wall of the material receiving container. The direct impact of the peanut kernels and the material receiving container is avoided to cause the seed coats to break, and the completeness of the peanut kernels is ensured.
