Description

Technical Field

[0001] The utility model belongs to the technical field of seed screening, and particularly relates to a screening device for early rice seed breeding and selection. Background Art

[0002] The screening device for early rice seed breeding and selection refers to the equipment used in the process of early rice seed breeding and selection, which is used to screen and select seeds with good growth characteristics and excellent qualities. The screening device is required for early rice seed breeding and selection.

[0003] For example, a Chinese patent with the publication number CN210614363U discloses a seed screening device for breeding and selection, which includes a box body. The box body includes a first screening cavity and a second screening cavity. A first screening net is inclined in the first screening cavity. The lower part of the first screening net is set as a first accommodating cavity. An exhaust fan and a second outlet are sequentially arranged on the left side wall of the first screening cavity. The lower part of the second screening net is the second screening cavity. The second screening cavity includes a third screening net, a fourth screening net and support plates arranged on both side walls. The third screening net and the fourth screening net are hinged by a rotating shaft. Both ends of the third screening net and the fourth screening net are hinged with a second connecting rod through a rotating part. The second connecting rod is hinged with a first connecting rod through a driven shaft. The end of the first connecting rod is connected with a rotating motor through a driving shaft. The rotating motor is arranged on the support plate.

[0004] The above can screen early rice seeds with relatively high screening efficiency. However, there are some defects in the existing early rice screening devices that need to be improved. When a large number of early rice seeds pour in from the raw material inlet and quickly accumulate on the screening net, this kind of accumulation on the screening net in a short time not only brings a heavy burden to the screening work of the screening net, but also hinders the smooth flow and uniform distribution of the seeds to a certain extent, thereby reducing the overall screening effect and significantly slowing down the screening efficiency.

One end of the first box body 1 is fixedly connected to a second box body 2. One end of the second box body 2 far from the first box body 1 is fixedly connected to a feed pipe 3. Both sides inside the second box body 2 are rotatably connected to guide plates 5 through shaft rods 4, and the two guide plates 5 are alternately inclined. One end of the shaft rod 4 extending out of the second box body 2 is fixedly connected to a first gear 6. One end of the second box body 2 is slidably connected to a push plate 7. Both sides of one end of the push plate 7 are provided with first tooth grooves 8. The first gear 6 is meshed with the first tooth grooves 8. A power assembly 9 is provided on the side of the push plate 7 far from the first gear 6. One side of the first box body 1 is hinged with a first box door 13. One end of the first box door 13 is fixedly connected to a fan 14. The other end of the first box door 13 is fixedly connected to an air outlet frame 15. One end of the first box body 1 far from the air outlet frame 15 is fixedly connected to a blocking frame 16. The air blown out by the fan 14 from the air outlet frame 15 can blow the dust in the early rice seeds to pass through the blocking frame 16, while the early rice seeds are blocked and cannot pass through. A sieve mesh 19 is provided inside the first box body 1. It should be noted that multiple sieve meshes 19 can be installed in the first box body 1. The pore diameters of the sieve meshes 19 decrease sequentially from top to bottom. Both sides of the lower end of the sieve mesh 19 are fixedly connected with vibration motors 20. Both sides of the lower end of the sieve mesh 19 are fixedly connected with springs 23. Through the above settings, a large number of seeds are prevented from quickly accumulating on the sieve mesh 19, thereby reducing the screening burden on the sieve mesh 19. At the same time, the seeds are smoothly and evenly distributed on the sieve mesh 19, which not only ensures the uniformity of screening but also significantly improves the screening effect of the seeds.

[0023] Reference Figure 2 , One end of the guide plate 5 close to the feed pipe 3 is fixedly connected to a stop block 12, and the side of the stop block 12 close to the shaft rod 4; By fixing the stop block 12 on the guide plate 5, a certain limiting effect is achieved to prevent the early rice seeds from running upward.

[0024] Reference Figure 3, the power assembly 9 includes a servo motor 91. The servo motor 91 is arranged on the second box body 2. The output end of the servo motor 91 is fixedly connected with a second gear 92. A second tooth groove 93 is formed at one end of the push plate 7 away from the first tooth groove 8. The second gear 92 is meshed and connected with the second tooth groove 93. A slider 94 is fixedly connected between the two first tooth grooves 8 on the push plate 7. On both sides of one end of the second box body 2 close to the push plate 7, first fixing blocks 96 are fixedly connected. A first sliding rod 95 is fixedly connected between the two first fixing blocks 96. The slider 94 is slidably connected to the first sliding rod 95. On one side of the second box body 2 close to the push plate 7, a frame 10 is fixedly connected. A shaft seat 11 is fixedly connected to the inner side of the frame 10. The servo motor 91 is rotationally connected to the frame 10 through the shaft seat 11; by setting the power assembly 9, the servo motor 91 drives the second gear 92 to rotate. The second gear 92 meshes with the second tooth groove 93 on the push plate 7 to move the push plate 7. The slider 94 connected to the push plate 7 slides on the first guide rod of the first fixing block 96, so that the first tooth groove 8 on the push plate 7 can be moved, thereby driving the first gear 6 to rotate, and then the material guiding plate 5 can be moved, preventing the early rice seeds from piling up and not falling. By setting the frame 10 and fixing the shaft seat 11 on the frame 10 and connecting the shaft rod 4 of the servo motor 91 to the shaft seat 11, the servo motor 91 can drive the second gear 92 to rotate smoothly.

[0025] Reference Figure 1 , at one end of the first box body 1 away from the first box door 13, a collection box 17 is fixedly connected. A second box door 18 is hinged to one side of the collection box 17; by fixing the collection box 17 on the first box body 1, the dust enters the collection box 17 for collection after passing through the blocking frame 16.

[0026] Reference Figure 2 , on both inner walls of the first box body 1, second fixing blocks 21 are fixedly connected. One end of the second fixing block 21 is fixedly connected to one end of a spring 23. On both lower sides of the sieve mesh 19, second sliding rods 22 are fixedly connected. One side of the second sliding rod 22 is slidably connected to the second fixing block 21; by setting the second fixing block 21, the spring 23 is fixed on the second fixing block 21. The second sliding rods 22 under the sieve mesh 19 slide inside the spring 23 and pass through the second fixing block 21 to guide the sieve mesh 19 to vibrate.

[0027] Principle of use and advantages: Early rice seeds enter the second box body 2 from the feed pipe 3. Guided by the material guiding plates 5 on both inner walls of the second box body 2, the time for the early rice seeds to fall onto the sieve mesh 19 is delayed, avoiding a large number of early rice seeds pouring in and quickly accumulating on the sieve mesh 19, causing a burden, and enabling the seeds to be smoothly and evenly distributed on the sieve mesh 19 for screening. The vibrating motor 20 vibrates the sieve mesh 19 through the spring 23 to screen the early rice seeds. The wind generated by the blower 14 blows out from the air outlet frame 15, which can blow the dust in the early rice seeds through the blocking frame 16 and be collected by the collection box 17, while the early rice seeds are blocked and cannot pass through. During the process of the early rice seeds falling on the material guiding plate 5, the servo motor 91 drives the second gear 92 to rotate. The second gear 92 meshes with the second tooth groove 93 on the pushing plate 7 to move the pushing plate 7. The slider 94 connected to the pushing plate 7 slides on the first guiding rod of the first fixing block 96, so that the first tooth groove 8 on the pushing plate 7 can move, thereby driving the first gear 6 to rotate, and then the material guiding plate 5 can be moved, avoiding the situation that early rice seeds accumulate on the material guiding plate 5 and providing guarantee for the falling of early rice seeds.
