Description

Technical Field

[0001] This utility model relates to the technical field of seed impurity removal equipment, specifically a device for removing impurities from legume seeds. Background Technology

[0002] Soybean is an annual herbaceous plant belonging to the genus *Glycine* of the legume family. It grows to a height of 30-90 cm, with a stout, erect stem densely covered with long, stiff brown hairs. It is a crop whose seeds are rich in plant protein. Soybeans are most commonly used to make various soy products, extract soybean oil, brew soy sauce, and extract protein. To ensure the germination rate of soybeans during cultivation, a purification device is needed during soybean breeding to remove impurities, bad beans, shriveled beans, and other waste that affects soybean breeding. A utility model patent with authorization number CN220611304U discloses a soybean breeding purification device, comprising: a side support frame, a cylinder, a feed hopper, side support rods, a tilting table, a vibrating feeding mechanism, and an air separation mechanism; the cylinder is hinged within the side support frame; the feed hopper is fixedly installed on the top of the side support frame; a pair of side support rods are both fixedly installed within the side support frame; and the tilting table is hinged between the pair of side support rods. The above-mentioned technical solution allows soybean seeds to be fed smoothly into the air-separation mechanism for impurity removal. However, a small amount of soybean seeds may remain in the inner ceramic tube of the dust collector, making cleaning extremely inconvenient. Therefore, this device includes a mechanism to prevent soybean seeds from entering the impurity removal mechanism. However, the above-mentioned technical solution only treats impurities in soybean seeds and cannot remove pathogens and molds carried on the seeds, nor can it kill insect eggs. This means that soybean seeds still require secondary sterilization and insect egg killing after impurity removal before sowing, significantly affecting the impurity removal effect. Therefore, we propose a soybean seed impurity removal device to solve the above problems. Utility Model Content

[0013] This utility model has the following advantages compared with the prior art:

[0014] 1. This utility model, by setting up a cleanup box in conjunction with an air separator and a slag discharge hood, ensures that lighter impurities are removed from bean seeds, preventing them from entering the soaking tank and floating on the surface of the sterilization solution, thus affecting the ultraviolet disinfection effect. After cleanup, the bean seeds are sent into the soaking tank and immersed in a 0.2% potassium permanganate solution pre-filled inside. The immersion in the potassium permanganate solution, combined with the special sterilization light provided by the ultraviolet sterilization lamp, effectively kills bacteria, mold, and insect eggs in the bean seeds.

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] like Figures 1 to 6 The illustrated device for removing impurities from legume seeds includes a soaking tank 1, with the bottom right side of the soaking tank 1 gradually sloping downwards. A removal box 2 is fixedly connected to the top right side of the soaking tank 1. An air separator 3 is fixedly connected to one side of the removal box 2, and a slag discharge hood 4 is fixedly connected to the other side of the removal box 2. Several ultraviolet germicidal lamps 5 are fixedly connected at intervals to the inner top wall of the soaking tank 1. An electronic level gauge 6 is installed on the soaking tank 1, with its detection end penetrating into the interior of the soaking tank 1. Three rollers 7 are rotatably connected inside the soaking tank 1, and a conveyor belt 8 is connected to the outer surfaces of the three rollers 7 for common transmission. The bottom end of the conveyor belt 8 corresponds to the lowest sloping end of the soaking tank 1. A servo motor 9 is connected to the outside of the soaking tank 1, with its output end penetrating the soaking tank 1 and fixedly connected to one end of one of the rollers 7. The outer surface of the conveyor belt 8 has equally spaced permeable holes 10. The outer surface of the conveyor belt 8 is fixedly connected with equidistantly arranged actuating plates 11. Both the conveyor belt 8 and the actuating plates 11 are made of rubber. The top of the soaking tank 1 is fixedly connected to a fixed shell 12. Several hot air blowers 13 are fixedly installed inside the fixed shell 12. Several drying lamps 14 are fixedly connected to the inner top wall of the fixed shell 12. A fixed plate 15 is fixedly connected to the inner wall of the soaking tank 1. The fixed plate 15 is located inside the conveyor belt 8. Four vibration springs 16 are fixedly connected to the upper surface of the fixed plate 15. The top of the four vibration springs 16 are fixedly connected to a vibration plate 17. The vibration plate 17 is located below the hot air blowers 13. The upper surface of the vibration plate 17 is in contact with the inner wall of the conveyor belt 8. A vibration motor 18 is connected to the bottom surface of the vibration plate 17. The two sides of the conveyor belt 8 are in contact with the soaking tank 1 to prevent the soybean seeds from falling out from the sides during vibration. A discharge port 27 is opened on the left side of the soaking tank 1.

[0025] The bottom surface of the soaking tank 1 is fixedly connected to a support frame 19. Each support frame 19 has two mounting through holes 20 at its bottom end. The support frame 19 and the mounting through holes 20 can support the soaking tank 1. At the same time, with the help of bolts and other fasteners, the device can be fixed in the working position, which increases the reliability of the device.

[0026] The top of the soaking tank 1 is fixedly connected to a liquid addition pipe 21, and the bottom of the soaking tank 1 is fixedly connected to a drain valve 22. The liquid addition pipe 21 allows staff to easily add a 0.2% potassium permanganate solution into the soaking tank 1, and the drain valve 22 allows wastewater from the soaking tank 1 after use to be discharged outwards.

[0027] An auxiliary shaft 23 is provided below the conveyor belt 8. The auxiliary shaft 23 is rotatably connected to the inside of the soaking tank 1. The outer surface of the auxiliary shaft 23 is in contact with the outer surface of the conveyor belt 8. The auxiliary shaft 23 can limit the position of the conveyor belt 8 inside the soaking tank 1 and adjust the tension of the conveyor belt 8 without affecting the rotation of the conveyor belt 8.

[0028] A stabilizing base 24 is fixedly connected to the bottom surface of the servo motor 9. One side of the stabilizing base 24 is fixedly connected to the outer surface of the soaking tank 1. The stabilizing base 24 can fix the position of the servo motor 9 on the soaking tank 1 and ensure that the servo motor 9 can operate normally.

[0029] Each hot air blower 13 has a reinforcing ring 25 fixedly connected to its outer surface. The bottom surface of each reinforcing ring 25 is fixedly connected to the upper surface of the fixed shell 12. The reinforcing ring 25 can reinforce the hot air blower 13, making it less likely to loosen and improving the connection between the hot air blower 13 and the fixed shell 12.

[0030] The left side of the fixed shell 12 has equidistantly arranged exhaust ports 26, which can discharge excess gas from the fixed shell 12 and the soaking tank 1. The discharge port 27 can ensure that the soybean seeds that have been cleaned, sterilized, killed insects and dried can be discharged smoothly from the inside of the soaking tank 1.

[0031] A sealing shell 28 is fitted on the outer surface of the vibratory motor 18. The upper surface of the sealing shell 28 is fixedly connected to the bottom surface of the vibrating plate 17. The sealing shell 28 can prevent water stains from entering the vibratory motor 18 and causing a short circuit without affecting the operation of the vibratory motor 18. The wires of the vibratory motor 18 can be connected to the vibratory motor 18 through the reserved holes on the sealing shell 28. The gap between the reserved holes on the sealing shell 28 and the wires is sealed by a rubber plug.

[0032] Several ultraviolet germicidal lamps 5 are fixedly connected at intervals to the inner top wall of the soaking tank 1.

[0033] The working process of this embodiment is as follows:

[0034] In use, first connect the ultraviolet germicidal lamp 5, electronic level gauge 6, servo motor 9, hot air blower 13, drying lamp 14, and vibration motor 18 to the external power supply and control switch. When it is necessary to remove impurities from bean seeds, first add a 0.2% potassium permanganate solution to the soaking tank 1 through the addition pipe 21. When adding the solution, the operator determines the liquid level inside the soaking tank 1 by observing the value of the electronic level gauge 6. Considering that the liquid level will rise after the bean seeds enter the soaking tank 1, only add the solution to half the depth of the soaking tank 1. Then, put the bean seeds into the impurity removal box 2. At this time, turn on the air separator 3. Using the air force provided by the air separator 3 in conjunction with the slag discharge hood 4, the light impurities in the bean seeds can be removed. Light impurities are blown out from the slag discharge hood 4 to prevent them from entering the soaking tank and floating on the surface of the sterilization solution, thus affecting the UV disinfection effect. Heavier soybeans fall downwards into the soaking tank 1. Utilizing the tilt angle of the soaking tank 1, the soybeans automatically slide into the depths. By weighing the soybeans as they are added, the weight of each batch added to the soaking tank 1 is controlled to approximately 50 kg. This prevents the potassium permanganate solution inside the soaking tank 1 from overflowing and also avoids poor UV lamp irradiation due to excessive soybean addition. Soybeans should be added gradually and slowly to ensure the air separation effect and to prevent the bottom soybeans from being difficult to cover by the UV lamp if added all at once. Gradual addition ensures... It achieves the effect of layered and gradual irradiation. After about 50 kilograms of soybean seeds are slowly and gradually introduced into the soaking tank 1, the staff turns off the air separator 3 and turns on the ultraviolet sterilizer 5, allowing the soybean seeds to soak in the soaking tank 1 for about 30 minutes. The sterilizing light from the ultraviolet sterilizer 5 and the potassium permanganate solution thoroughly kill pathogens, bacteria, and insect eggs in the soybean seeds. After 30 minutes, the staff turns off the ultraviolet sterilizer 5 and turns on the servo motor 9, hot air blower 13, drying lamp 14, and vibration motor 18. Using the power provided by the servo motor 9, in conjunction with the roller 7, auxiliary shaft 23, and the actuating plate 11 on the conveyor belt 8, the soybean seeds inside the soaking tank 1 are discharged outwards. As the soybean seeds rotate with the conveyor belt 8... After being discharged, the hot air generated by the hot air blower 13, combined with the heating of the drying lamp 14, can heat and dry the soybeans. The vibration force provided by the vibration motor 18, in conjunction with the fixed plate 15, vibration spring 16 and vibration plate 17, can force the soybeans on the conveyor belt 8 to vibrate. The round shape of the soybeans forces them to turn over automatically, ensuring the drying effect. Finally, the potassium permanganate solution inside the soaking tank 1 can be used a maximum of about five times. As the number of uses increases, the time the soybeans stay in the soaking tank 1 also needs to be increased. When the concentration of the potassium permanganate solution drops excessively after multiple uses, the wastewater inside the soaking tank 1 can be discharged through the drain valve 22, and then new potassium permanganate solution can be added.
