Grain seed sorting and processing equipment and method

Abstract

The invention discloses a grain seed sorting and processing device and method. The grain seed sorting and processing device comprises a hollow box body, a feeding hole is formed in the top end of thehollow box body, a first screen and a second screen are arranged in the box from top to bottom, the two sides are provided with a first air inlet and a first impurity removing opening respectively andare externally connected with an air blower and an impurity collecting box respectively; the second screen is obliquely arranged and corresponds to a first discharge port; a vibration mechanism comprises a supporting column, a first spring, a second spring and a vibration motor, the supporting column is sleeved with the first spring and is connected with the vibration motor, the first end of thesupporting column is connected with the screen, and the second end of the supporting column is connected with the box body through the second spring; a processing device comprises a conveying belt anda stirring box, the conveying belt is connected with the first discharging opening and the stirring box, a stand column is arranged at the bottom end of the stirring box, a first rotating shaft and astirring plate are transversely arranged in the middle of the stand column, the top end of the second rotating shaft is sequentially provided with a supporting plate and a second rotating shaft, anda spraying pipe is arranged on the side face of the second rotating shaft. According to the grain seed sorting and processing device, a full grain is screened by combining winnowing and vibration, rotating and dispersing the grains and spraying the liquid medicine, and then turning stirring to enable the liquid medicine to be more uniform.

Description

technical field [0001] The invention relates to the technical field of seed processing equipment, in particular to a sorting and processing equipment and method for grain seeds. Background technique [0002] High-quality grain seeds are an important basis for the generation of grains. Grain seeds will be dried after they are mature and harvested. Dry seeds contain many impurities such as straw, miscellaneous leaves, gravel and a lot of dust, etc., or there are some immature, Mildewed grains, etc. need to be cleaned and sorted to separate impurities in grain seeds and some shriveled, mildewed and damaged grains, so as to avoid affecting the germination rate; in addition, in order to improve the germination rate of grain seeds and prevent some For pests and diseases, the seeds are generally coated with liquid medicine before sowing. The amount of coating should not be too much or too little, so as not to affect the emergence rate. At present, there are patents that disclose e...

Problems solved by technology

At present, there are patents that disclose equipment for processing seeds. The patent application number 201710652209.X discloses a sorting and processing equipment and method for grain seeds. The patent includes a seed screening unit and a drug injection unit. The screening unit first uses The method of vibrating screening is to screen the seeds to screen out the high-quality seeds. Although the screening unit is set with the discharge end of the good-grade seeds and the discharge end of the low-grade seeds, and the weight sensor installed on the support part of the vibrating bucket senses different weights, so as to Distinguish between good and inferior seeds. Among the selected good seeds, there are many damaged, mildewed or shriveled seeds. Once there are moldy seeds, it will be very unfavorable for storage, and this process is carried out in an open environment. The dust cannot be removed well; the injection unit is provided with a spiral dispensing tube, and the dispensing liquid injection tube enters the dispensing inner cavity of the spiral dispensing tube of each layer through the injection hole. Due to the existence of the spiral structure, even if the injection hole is from However, when the liquid medicine flows down with the spiral structure, and the strands of seeds pass through the dispensing cavity of the spiral dispensing tubes of each layer, even if they are subjected to vibration and tumbling continuously, it cannot ensure that the medicine is evenly coated, and the medicine The liquid and seeds finally gather at the bottom, so that the seeds in the lower layer will be in contact with the liquid medicine in large quantities, so that the seeds in the upper layer and the lower layer are not uniformly coated.
