Abstract
Description
Technical Field
[0001] This utility model relates to the field of cotton seed screening technology, and more specifically, to a seed screening device for cotton cultivation. Background Technology
[0002] Cotton is the seed fiber of plants in the genus Gossypium of the Malvaceae family. It originated in subtropical regions and is a shrub-like plant. It is one of the world's most important crops, with high yields and low production costs, making cotton products relatively inexpensive. Cotton fibers can be made into fabrics of various specifications, from light and transparent voile to thick canvas and velvet, suitable for making various types of clothing, furniture fabrics, and industrial fabrics. In order to ensure the quality of cotton cultivation, cotton seeds need to be screened and impurities removed before cultivation.
[0003] A seed screening device for cotton cultivation disclosed in Chinese utility model patent application CN217250649U, although it prevents cotton seeds from falling freely through a rectangular frame by pouring them into a storage hopper and using a roller to block the rectangular frame, and using a geared motor to drive the roller to rotate at low speed so that the cotton seeds can enter the quantitative trough sequentially, has obvious defects. The cotton seeds fall in different postures, and when blown by the fan, the force angle and area on them are different, making it difficult to completely remove some impurities and shriveled inferior seeds, which seriously affects the screening effect. In the process of use, if the screening effect is to be improved, the screening operation often needs to be repeated many times. In addition, the quantitative feeding mechanism is located at the top of the device. When feeding, the workers need to lift the cotton seeds to be screened before putting them in, which is extremely inconvenient. In summary, this utility model has the problems of poor screening effect and inconvenient feeding. Utility Model Content

[0026] Please see Figures 1-6 A seed screening device for cotton cultivation includes a housing 1, a feeding funnel 2 fixedly connected to the left side of the housing 1, a feeding port 3 opened on the lower side of the outer surface of the housing 1 inside the feeding funnel 2, a feeding mechanism, a screening mechanism, and an adjustment mechanism on the inner side wall of the housing 1, a control switch 23 fixedly connected to the front of the housing 1, and an air inlet 24 opened on the front of the housing 1 outside the centrifugal fan 8.
[0027] The feeding mechanism includes a rotating roller 4, a conveyor belt 5 rotatably connected to the outer surface of the rotating roller 4, a feeding inclined plate 6 fixedly connected to the outer surface of the conveyor belt 5, and several feeding inclined plates 6 evenly distributed on the outer surface of the conveyor belt 5. A drive motor 11 is fixedly connected to the inner bottom wall of the equipment shell 1. A first pulley 12 is fixedly connected to one end of the output shaft of the drive motor 11. A second pulley 13 is fixedly connected to one end of the rotating roller 4. The outer surface of the second pulley 13 is connected to the outer surface of the first pulley 12 via a belt 14. A protective shell 15 is fixedly connected to the outer surface of the equipment shell 1 outside the first pulley 12, the second pulley 13 and the belt 14.
[0028] The screening mechanism includes a first guide plate 7, which is fixedly connected to the upper side of the inner wall of the equipment housing 1. A centrifugal fan 8 is fixedly connected to the inner wall of the equipment housing 1 below the first guide plate 7. A partition 9 is fixedly connected to the inner wall of the equipment housing 1 to the right of the air outlet of the centrifugal fan 8. An impurity storage box 20 is slidably connected to the inner wall of the equipment housing 1 to the right of the partition 9 via a slide rail. A filter screen 21 is fixedly connected to the inner bottom wall of the impurity storage box 20. A seed storage box 22 is movably connected to the inner wall of the equipment housing 1 to the left of the partition 9.
[0029] The adjustment mechanism includes an inverted Y-shaped plate 10, which is arranged in an inverted Y shape. A hinge block 16 is fixedly connected to the upper end of the inverted Y-shaped plate 10. An adjustment ramp 17 is rotatably connected to the inner side wall of the hinge block 16 via a rotating shaft 18. One side of the upper end of the adjustment ramp 17 abuts against the outer surface of the partition 9. A crank handle 19 is fixedly connected to the front end of the rotating shaft 18 through the front of the equipment housing 1.
[0030] Specifically, the cotton seeds to be screened can be easily fed into the equipment from a lower position through the feeding hopper 2 and the feeding port 3. The drive motor 11 is started, and its output shaft drives the first pulley 12 to rotate. The first pulley 12 drives the second pulley 13 to rotate via the belt 14, which in turn causes the rotating roller 4 to rotate. The rotating roller 4 drives the conveyor belt 5 to rotate. The feeding inclined plates 6, evenly distributed on the outer surface of the conveyor belt 5, move with the rotation of the conveyor belt 5. The cotton seeds fall from the feeding port 3 onto the feeding inclined plates 6. As the feeding inclined plates 6 rise, they are conveyed to a higher position, facilitating feeding. After being conveyed to a higher position by the feeding inclined plates 6, the cotton seeds fall onto the first guide plate 7 and slide down along the first guide plate 7 under the action of gravity. At this time, the centrifugal fan 8 is started, and the centrifugal fan 8 produces... The wind blows impurities and shriveled, inferior seeds from the cotton seeds to the right. These impurities and shriveled, inferior seeds pass through the filter screen 21 and fall into the impurity storage box 20 for collection. Meanwhile, the better quality cotton seeds fall to the left into the seed storage box 22 under the combined action of wind and gravity, completing the initial screening. When it is necessary to screen the cotton seeds again, turn the crank handle 19. The crank handle 19 drives the rotating shaft 18 to rotate. The rotating shaft 18 drives the adjusting inclined plate 17 to rotate around the hinge block 16, changing the tilt direction of the adjusting inclined plate 17. This allows the cotton seeds after the initial screening to fall onto the adjusting inclined plate 17 and then roll onto the inverted Y-shaped plate 10. Subsequently, the cotton seeds will fall onto the feeding inclined plate 6 again and be conveyed upwards again with the operation of the conveyor belt 5, realizing multiple screenings and effectively improving the screening effect.
[0031] In summary, when using the overall equipment:
[0032] When using this device, the cotton seeds to be screened are poured directly into the feed hopper 2. The control switch 23 is turned on, and the drive motor 11 and centrifugal fan 8 begin to work. The drive motor 11 drives the rotating rollers 4 to rotate, which in turn causes the conveyor belt 5 to travel over the outer surfaces of the two rotating rollers 4. After the cotton seeds enter the equipment casing 1 from the feed inlet 3, they fall onto the multiple feeding inclined plates 6 on the left side. After being conveyed upwards, they fall onto the first guide plate 7 and slide down due to the overturning of the feeding inclined plates 6. At this time, the centrifugal fan... Air is drawn from the air inlet 24 and sprayed out, blowing the cotton seeds to the right. Shriveled seeds and light impurities are blown further and fall into the impurity storage box 20. Seeds that are not blown past the partition 9 slide to the left through the adjusting inclined plate 17 to the inverted Y plate 10, and then enter the transmission area of the feeding inclined plate 6 again. After being driven upward, the seeds are circulated and screened. After multiple screenings, the rocker handle 19 is turned to tilt the adjusting inclined plate 17 to the left, removing the obstruction above the seed storage box 22. Qualified seeds fall into it, completing multiple screenings.
