Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1 to 5, a seed magnetic separation and classification device includes a mixing mechanism, a filtering mechanism and a separating mechanism 13. The mixing mechanism comprises a stirring cylinder 11, and the stirring cylinder 11 is communicated with a seed feeding hopper 6 and a magnetic powder feeding hopper 8. The filtering mechanism comprises a seed guide groove 12 which is obliquely arranged, the upper end of the seed guide groove 12 is positioned below the outlet of the stirring barrel 11, a plurality of separation holes 19 are formed in the seed guide groove 12, and the aperture of each separation hole 19 is larger than the particle size of the magnetic powder and smaller than the particle size of the seeds. The separating mechanism 13 comprises a plurality of separating units which are sequentially arranged up and down, the uppermost separating unit is positioned below the seed guide groove 12, the separating unit comprises a sleeve 34 which is vertically arranged, the lower end of the sleeve 34 is closed, the upper end of the sleeve 34 is fixedly sleeved with a fixed disc 29, a fan-shaped notch 30 is formed in the fixed disc 29, a second motor 35 is fixedly arranged in the sleeve 34, a motor shaft 22 of the second motor 35 extends out of the sleeve 34 upwards, a rotating disc 24 and a permanent magnet ring 23 are fixedly sleeved on the motor shaft 22, the rotating disc 24 is attached to the fixed disc 29, a plurality of fan-shaped through grooves 25 which are uniformly distributed along the circumferential direction are formed in the rotating disc 24, the central angle corresponding to the through grooves 25 is smaller than the central angle corresponding to the notch 30, the lower end of the sleeve 34 is fixedly connected with a horizontally extending supporting plate 33, all the supporting plates 33 are jointly connected with an external supporting mechanism, a spiral seed collecting groove 21 is fixedly arranged on the supporting plate 33, the spiral seed collecting groove 21 is coaxially arranged with the sleeve 34, and the spiral seed collecting groove 21 is lower than the fixed disc 29. The rotational speeds of all the second motors 35 are gradually increased from top to bottom.
When the seed feeding hopper is used, seeds to be graded are firstly put into the stirring barrel 11 through the seed feeding hopper 6, the magnetic powder is put into the stirring barrel 11 through the magnetic powder feeding hopper 8, then the magnetic powder and the seeds are fully mixed by the stirring barrel 11, the magnetic powder is adsorbed on the surfaces of the seeds under the action of fluff on the surfaces of the seeds, and if cracks exist on the surfaces of the seeds, the magnetic powder enters the cracks, so that more magnetic powder is adsorbed on the seeds. After the mixing is completed, the seeds adsorbed with the magnetic powder and the redundant magnetic powder are jointly sent into the seed guide groove 12 through the outlet of the stirring barrel 11, and the redundant magnetic powder can fall from the separation hole 19 because the aperture of the separation hole 19 is larger than the particle size of the magnetic powder, so that only the seeds adsorbed with the magnetic powder can smoothly fall into the separation mechanism 13 through the seed guide groove 12, and the fallen magnetic powder can be collected for reuse. After the seeds adsorbed with the magnetic powder fall into the separating mechanism 13, the seeds firstly fall onto the rotating disk 24 of the uppermost first separating unit and rotate with the rotating disk 24, because the seeds with less adsorbed magnetic powder are lighter in weight and are less attracted by the permanent magnet ring 23, the seeds are thrown into the spiral seed collecting groove 21 of the first separating unit under the centrifugal action, then move downwards along the spiral seed collecting groove 21 until falling from the spiral seed collecting groove 21, and the seeds have the least surface cracks and the best quality because the adsorbed magnetic powder is least. On the other hand, seeds with more adsorbed magnetic powder cannot be thrown out under the action of the permanent magnet ring 23 until the rotating disc 24 rotates to the state that the through groove 25 is communicated with the notch 30 and falls down into the second separation unit for classification again. In the second separation unit, since the magnetic powder adsorbed by the seeds is relatively large, the rotation speed of the second motor 35 of the second separation unit is increased in order to smoothly perform classification, and the amount of the magnetic powder adsorbed by the seeds dropped from the spiral seed collecting groove 21 of the second separation unit is high, so that the quality is poor. The number of stages is (n+1) if the number of stages is n, and in this embodiment, three separation units are provided, and the number of corresponding stages is four. The classified seeds can be separated from the magnetic powder by other modes, such as rapid vibration of the seeds adsorbed with the magnetic powder, the magnetic powder is peeled off by means of the impact force of vibration and mutual collision and friction between the seeds, or the seeds adsorbed with the magnetic powder are immersed into a detergent, and then the magnetic powder is separated from the seeds by stirring or ultrasonic vibration to be mixed into the detergent, or the seeds are separated from the magnetic powder by multiple cleaning by a grain cleaner.
The invention utilizes the adsorption effect of the fluff and the cracks on the surface of the seeds to grade the seeds, effectively takes the surface cracks as the grading basis, can screen out high-quality seeds more accurately compared with the existing mode which only uses weight and volume as the grading basis, does not need complex data acquisition and calculation analysis processes, and is more practical and lower in cost.

The seeds are moved to the outlet direction of the mixing drum 11 by the spiral blade 10 after entering the mixing drum 11 through the seed feeding hopper 6, and are contacted with the magnetic powder entering the mixing drum 11 through the magnetic powder feeding hopper 8 in the process, and then the seeds and the magnetic powder are moved to the outlet together and are fully and uniformly mixed in the moving process. The mode of conveying and mixing by adopting the bolt blades 10 can effectively avoid damaging seeds, and the classification accuracy is ensured.
Further, the churn 11 level sets up, and seed feeder hopper 6 and magnetic powder feeder hopper 8 all set up perpendicularly, all are provided with a plurality of deflector 7 in seed feeder hopper 6 and the magnetic powder feeder hopper 8, and deflector 7 downward sloping sets up, and all deflector 7 divide into two sets of, and two sets of deflector 7 set up relatively and the guide way of crisscross formation zigzag each other. Seeds and magnetic powder continuously impact on the guide plate 7 in the falling process, so that the speed can be effectively reduced, and the zigzag guide channel prolongs the moving distance of the seeds and the magnetic powder, so that the seeds and the magnetic powder are prevented from being blocked.
In order to further avoid blockage, the elastic vibrating plate 36 is horizontally arranged at the communication part between the seed feeding hopper 6 and the stirring cylinder 11 and the communication part between the magnetic powder feeding hopper 8 and the stirring cylinder 11, when seeds or magnetic powder fall onto the elastic vibrating plate 36, the elastic vibrating plate 36 is impacted, and the elastic vibrating plate 36 vibrates to enable a part of the seeds or the magnetic powder to jump upwards, so that blockage is avoided.

The gathering tank 20 can gather the seeds adsorbed with the magnetic powder, so that the coverage area is smaller when the seeds fall onto the rotating disc 24, and the reduction of classification accuracy caused by the fact that the seeds fall into the spiral seed collecting tank 21 directly after insufficient rotation is avoided.
