[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0021] Example
[0022] Please refer to Figures 1-4 The selenium-enriched rice seed cleaning device of this utility model mainly includes a cleaning box 1.
[0023] The washing tank 1, as the main body of the entire device, provides a closed working space for seed washing and impurity separation. A rotatable shaft 2 is arranged axially inside the washing tank 1; this shaft 2 is a key component for achieving seed washing and stirring functions. A vibrating filter frame 4 is located inside the washing tank 1, at the top of the shaft 2, for preliminary screening to remove large particles of impurities from the seeds. Two sets of sealing plates 13 are located inside the washing tank 1, at the middle of the shaft 2; these two sets of sealing plates 13 can move towards or away from each other to separate seeds and small particles of impurities during the washing process. Multiple stirring sleeves 12 are located inside the washing tank 1, at the bottom of the shaft 2, for thorough stirring and washing of the seeds. A discharge pipe 14 is located at the bottom of the washing tank 1 for discharging the washed seeds and impurities.
[0024] Multiple placement frames 3 are inserted into the top of the washing tank 1. The top and bottom of each placement frame 3 are open to allow seeds to enter and pass through smoothly. The number of filter frames 4 corresponds to the number of placement frames 3, and each filter frame 4 is detachably installed in one placement frame 3 via a snap-fit mechanism. This detachable installation method facilitates regular disassembly and cleaning of the filter frames 4, ensuring their screening effect.
[0025] The inner wall of the top of the cleaning tank 1 is provided with a mounting groove 101, and the side of the placement frame 3 is slidably connected to the mounting groove 101 via a slider 19. The slider 19 and the placement frame 3 are fixedly connected by welding to ensure the stability of the connection. A vibration motor 16 is provided at the bottom of the slider 19, and the vibration motor 16 is fixedly installed at the bottom of the slider 19 by bolts.
[0026] When the vibration motor 16 is working, it can drive the placement frame 3 and the filter screen frame 4 to vibrate together. Simultaneously, a telescopic sleeve 17 connects the bottom of the slider 19 and the mounting groove 101, and a spring 18 is fitted onto the surface of the telescopic sleeve 17. One end of the telescopic sleeve 17 is fixedly connected to the bottom of the slider 19 by welding, and the other end is fixedly connected to the bottom of the mounting groove 101 by welding. Both ends of the spring 18 are tightly fitted to the bottom of the slider 19 and the bottom of the mounting groove 101, respectively. This structure can buffer and stabilize the vibration process, ensuring the vibration effect while avoiding excessive damage to the equipment.
[0027] To drive the rotating shaft 2 to rotate, the device also includes a rotating assembly. The rotating assembly includes a top mounting bracket 5 and a drive motor 6. The top mounting bracket 5 is fixedly mounted on the top of the cleaning tank 1 by bolts, serving to support and fix the drive motor 6.
[0028] The drive motor 6 is bolted to the top mounting bracket 5. The top side of the rotating shaft 2 is rotatably connected to the top mounting bracket 5 via bearings, ensuring smooth rotation of the rotating shaft 2. A first gear 61 is connected to the output shaft of the drive motor 6, and the first gear 61 is fixedly connected to the output shaft of the drive motor 6 via a key. A second gear 7 is connected to the top of the rotating shaft 2, and the second gear 7 is fixedly connected to the top of the rotating shaft 2 via a key. The first gear 61 and the second gear 7 mesh, and the stable rotation of the rotating shaft 2 is achieved through the operation of the drive motor 6.
[0029] The cleaning tank 1 has connection ports 100 on both sides. One side of the sealing plate 13 is inserted into the connection port 100. The sealing plate 13 and the connection port 100 are fitted with a clearance fit to ensure that the sealing plate 13 can move smoothly and to prevent the cleaning fluid from leaking. The side of the sealing plate 13 away from the cleaning tank 1 has a handle 11. The handle 11 is fixedly connected to the sealing plate 13 by welding, which facilitates the operator to manually control the movement of the sealing plate 13.
[0030] A scraper block 131 is connected to the inner wall of the cleaning tank 1 near the sealing plate 13. The scraper block 131 is fixedly installed on the inner wall of the cleaning tank 1 by bolts. The bottom end of the scraper block 131 is in contact with the top side of the sealing plate 13. When the sealing plate 13 is pulled out, the scraper block 131 can scrape off the impurities on the top of the sealing plate 13.
[0031] A sealing ring is provided on the inner side of the connection port 100. The sealing ring is made of rubber and is installed on the inner side of the connection port 100 by interference fit to ensure the sealing of the device and prevent the cleaning fluid from leaking.
[0032] The device also includes a liquid-passing assembly, which includes a water tank 8, a water pump, and a liquid-passing pipe 15. The bottom end of the liquid-passing pipe 15 extends into the interior of the rotating shaft 2. The liquid-passing pipe 15 and the rotating shaft 2 are connected by a sealed bearing, which ensures that the liquid-passing pipe 15 can rotate with the rotating shaft 2 and prevents the cleaning fluid from leaking.
[0033] One end of the agitator sleeve 12 extends into the interior of the rotating shaft 2 and is connected to the liquid passage pipe 15. The agitator sleeve 12 and the liquid passage pipe 15 are fixedly connected by welding to ensure the sealing of the connection. Multiple spray heads 121 are connected to the agitator sleeve 12. The spray heads 121 are fixedly connected to the agitator sleeve 12 by threaded connection. A filter screen sleeve 122 is connected to the end of the spray head 121 away from the agitator sleeve 12. The filter screen sleeve 122 is fixedly connected to the spray head 121 by a snap-fit structure, which can prevent impurities from entering the liquid passage pipe 15.
[0034] The water tank 8 is bolted to the top mounting bracket 5. The input end of the water pump is connected to the inside of the water tank 8, and the input end of the water pump is connected to the bottom of the water tank 8 through a pipe. The pipe and the water tank 8 are sealed with a sealing ring. The output end of the water pump is connected to the top of the liquid inlet pipe 15 through a rotary joint 9. The rotary joint 9 ensures that the cleaning fluid can still be smoothly delivered from the water pump to the liquid inlet pipe 15 even when the shaft 2 is rotating.
[0035] A valve is installed on the discharge pipe 14. The valve is a ball valve and is fixedly connected to the discharge pipe 14 through a flange connection. This facilitates the control of the timing of seed and impurity discharge and ensures the smooth progress of cleaning and separation.
[0036] Specifically, during the cleaning process, the seeds to be cleaned are placed into the filter frame 4, and the vibration motor 16 is started. The vibration motor 16 drives the slider 19 to slide up and down in the mounting groove 101, thereby causing the placement frame 3 and the filter frame 4 to vibrate together. During the vibration process, large particles of impurities are retained in the filter frame 4, while the seeds pass through the filter frame 4 and enter the bottom of the cleaning tank 1.
[0037] Then, the water pump is started, allowing the cleaning solution in the water tank 8 to be pumped to the rotary joint 9, and then through the liquid pipe 15 into the stirring sleeve 12 and the spray head 121. Simultaneously, the drive motor 6 is started, and the output shaft of the drive motor 6 drives the first gear 61 to rotate. The first gear 61 drives the meshing second gear 7 to rotate, thereby driving the rotating shaft 2 to rotate. The rotating shaft 2 drives the stirring sleeve 12 to rotate, cleaning the seeds. The cleaning solution is sprayed from the spray head 121 and, under the stirring action of the stirring sleeve 12, comes into full contact with the seeds, washing away impurities from the seed surface.
[0038] After a period of cleaning, stop the drive motor 6 and water pump, and let the liquid in the cleaning tank 1 stand still. At this time, small particulate impurities will float to the top of the water surface. Then, move the two sealing plates 13 in opposite directions by using the handle 11 to separate the seeds from the small particulate impurities.
[0039] Finally, open the valve on the discharge pipe 14 to remove the washed seeds. After removing the seeds, detach the two sealing plates 13 from the inside of the washing tank 1. The impurities are then guided into the washing tank 1 through the sealing plates 13. Open the valve on the discharge pipe 14 again to remove the impurities, thus achieving the effect of impurity separation.
[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
