Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of agricultural production devices, and specifically relates to a seed screening device. Background Art
[0002] Peanut is a crop with high nutritional value and one of the main oil varieties of high-quality edible oil. It is also known as "peanut" or "longevity fruit". Peanut is an annual herb. It originated in tropical and subtropical regions of South America and is one of the important economic crops in my country. When planting peanuts, in order to ensure the quality of planting, it is necessary to screen out peanut seeds with better quality. Usually, peanut seeds with good quality have the characteristics of full grains and uniform skin color, while peanut seeds with poor quality have the characteristics of small grain quality. At the same time, some peanut seeds will have surface wrinkles, and the seed coat will become yellow-brown or dark red. Such peanut seeds generally cannot germinate. The existing seed screening equipment mainly screens through a sieve. Although it can improve the overall quality of seeds to a certain extent, it still cannot avoid mixing in peanut seeds of poor quality. Utility Model Content
[0003] In view of the above-mentioned technical problems, the utility model provides a seed screening device to solve the problem of insufficient screening quality of existing screening devices for peanut seeds. The seed screening device can effectively screen out bad seeds and improve the seed screening quality.
[0004] The utility model provides a seed screening device, comprising a blanking hopper, a transparent blanking plate, a CCD recognition array, a fan array, a controller and a collecting trough, wherein the transparent blanking plate is vertically arranged, the top of the transparent blanking plate is connected to the bottom of the blanking hopper, a plurality of blanking channels are arranged side by side in the transparent blanking plate, the CCD recognition array is arranged on one side of the transparent blanking plate, a plurality of CCD cameras are arranged along the horizontal direction of the CCD recognition array, a plurality of CCD cameras are arranged one-to-one with a plurality of blanking channels, the fan array is located on the lower side of the transparent blanking plate, a plurality of blowers are arranged along the horizontal direction of the blower array, a plurality of blowers are arranged one-to-one with the lower outlets of the plurality of blanking channels, a plurality of blowers are respectively provided with an independent wind control device, a superior seed collection trough and a inferior seed collection trough are arranged side by side in the collecting trough, the superior seed collection trough is located directly below the transparent blanking plate, the inferior seed collection trough is located on the side of the superior seed collection trough away from the fan array, and the controller is electrically connected to a plurality of CCD cameras and a plurality of wind control devices respectively.
[0005] Furthermore, a strip light source is arranged below the CCD recognition array.
[0006] Furthermore, a vibration mechanism is provided on the side wall of the drop hopper.
[0007] When the seed screening device is performing seed screening operations, peanut seeds can be added through the drop hopper, and the lower outlet width of the drop hopper is slightly larger than the outer diameter of the peanut seeds, so that the peanut seeds fall along the multiple drop channels. During the falling of the peanut seeds, the blowing array is maintained at a low wind speed state. At this time, poor peanuts with small particle quality will be blown into the poor seed collection trough by wind force, while peanut seeds with fuller particle quality will fall into the superior seed collection trough. At the same time, during the falling of the peanut seeds in the drop channel, the CCD recognition array identifies the color of the peanuts in each drop channel. When the color of the peanut seeds is too dark, the controller controls the blower under the corresponding drop channel to increase the wind speed, and blows the darker seeds into the poor seed collection trough, thereby effectively improving the seed screening quality. BRIEF DESCRIPTION OF THE DRAWINGS
[0008] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.
