Description

Technical Field

[0001] The utility model belongs to the technical field of air selection, and in particular relates to an air selection device for cultivating rice seeds. Background Art

[0002] Seeds generally consist of three parts: seed coat, embryo and endosperm. The mature seeds of some plants only have two parts: seed coat and embryo. The formation of seeds allows the young sporophyte ovule to be protected by the mother and get sufficient nutrients like the fetus of a mammal.

[0003] Generally, crop seeds need to be screened after harvest to improve the overall seed quality. For seed air separation devices in the prior art, some impurities will fall with the seeds during the air separation process due to their own large gravity, which ultimately leads to poor air separation effect. In addition, there is the possibility of blockage when the seeds are fed into the machine. Therefore, the present application proposes a air separation device for cultivating rice seeds.

For seed wind selection devices in the prior art, some impurities will fall with the seeds during the wind selection process due to their own large gravity, which ultimately leads to poor wind selection effect. In addition, there is the problem of blockage when the seeds are fed in.

[0008] Furthermore, the air separation mechanism includes an air separation box, a side wall of which is provided with an air blowing mechanism, a second screening mechanism is provided in the middle of the inner cavity of the air separation box, and an impurity collecting mechanism corresponding to the second screening mechanism is provided on the other side wall of the air separation box.

[0009] Furthermore, the second screening mechanism includes two screening components fixed in sequence from top to bottom in the inner cavity of the air separation box, and the screening components include a sieve fixed to the middle part of the inner cavity of the air separation box through a connecting rod, and the aperture of the upper sieve is larger than the aperture of the lower sieve.

[0010] Furthermore, the blowing mechanism includes an air supply fan fixed to the outer wall of the air separation box, the air supply fan is connected to an air supply main pipe, the other end of the air supply main pipe extends through the side wall of the air separation box to the inner cavity of the air separation box and is connected to two air outlet boxes, and the air outlets of the two air outlet boxes correspond to a screen respectively.

DETAILED DESCRIPTION

[0022] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0023] See also Figure 1-Figure 2 .

[0024] Generally, crop seeds need to be screened after harvest to improve the overall seed quality. For the seed air selection device in the prior art, some impurities will fall with the seeds during the air selection process due to their own large gravity, which ultimately leads to poor air selection effect. In addition, when the seeds are fed, there may be a situation of material blockage. Therefore, the present application proposes a wind selection device for cultivating rice seeds, including a feeding mechanism, the bottom of the feeding mechanism is connected to a first screening mechanism, the bottom of the first screening mechanism is connected to the air selection mechanism through a through slot 1, and the bottom of the inner cavity of the air selection mechanism is provided with a seed collecting mechanism;

[0025] The feeding mechanism includes a feeding hopper 2, the bottom of which is connected to the first screening mechanism, a feeding bin 4 is fixed to the inner cavity of the feeding hopper 2 through a fixing rod 3, a plurality of feeding branch pipes 5 are evenly connected to the bottom of the feeding bin 4, and the plurality of feeding branch pipes 5 extend into the inner cavity of the first screening mechanism. Specifically, seeds are passed into the feeding bin 4, and the seeds are passed into the feeding box 10 of the first screening mechanism from the plurality of feeding branch pipes 5 evenly connected to the bottom of the feeding bin 4. Here, by setting a plurality of feeding branch pipes 5, the seeds are diverted and flowed out to prevent the seeds from being blocked during the feeding process;

[0026] The first screening mechanism includes a motor 6 fixed to the inner cavity of the first screening mechanism, the output end of the motor 6 is fixedly connected to the first rotating rod 7, the other end of the first rotating rod 7 is rotatably connected to the second rotating rod 8, the other end of the second rotating rod 8 is rotatably connected to the fixed block 9, the other end of the fixed block 9 is fixedly connected to the discharge box 10, the discharge box 10 is slidably arranged in the through slot 1, and a filter screen 11 is arranged at the bottom of the discharge box 10. Specifically, by starting the motor 6, the motor 6 drives the first rotating rod 7 to rotate, and the rotation of the first rotating rod 7 drives the second rotating rod 8 to rotate, and at the same time drives the discharge box 10 to move back and forth in the through slot 1. Since the filter screen 11 is arranged at the bottom of the discharge box 10, the discharge box 10 filters out some impurities with larger self-gravity in the seeds during the process of moving back and forth in the through slot 1, so as to perform the first screening of the seeds.

[0027] Furthermore, the air separation mechanism includes an air separation box 12, a side wall of which is provided with an air blowing mechanism, a middle part of the inner cavity of the air separation box 12 is provided with a second screening mechanism, and the other side wall of the air separation box 12 is provided with an impurity collecting mechanism corresponding to the second screening mechanism. Specifically, by starting the coordinated use of the air blowing mechanism and the second screening mechanism, the seeds passed into the inner cavity of the air separation box 12 can be screened, and the screened impurities can be collected into the impurity collecting mechanism.

[0028] Furthermore, the second screening mechanism includes two screening components fixed in sequence from top to bottom in the inner cavity of the air separation box 12, the screening component includes a screen 14 fixed to the middle part of the inner cavity of the air separation box 12 through a connecting rod 13, and the aperture of the upper screen 14 is larger than the aperture of the lower screen 14; the air blowing mechanism includes an air blower 15 fixed to the outer wall of the air separation box 12, the air blower 15 is connected to an air supply main pipe 16, and the other end of the air supply main pipe 16 passes through the side wall of the air separation box 12 and extends to the inner cavity of the air separation box 12 There are two air outlet boxes 17 connected to each other, and the air outlets of the two air outlet boxes 17 correspond to a screen 14 respectively. Specifically, the blower 15 is started, and the wind is sent into the air supply main pipe 16, and finally the wind is blown out through the two air outlet boxes 17, so that when the seeds in the air separation box 12 pass through the two screens 14 in turn, the excess impurities mixed in the seeds are blown to the impurity collection mechanism. It should be noted here that the aperture of the upper screen 14 is larger than the aperture of the lower screen 14, which can further improve the screening effect.

[0029] Furthermore, two impurity collecting mechanisms are provided, and the two impurity collecting mechanisms correspond to the two screening components respectively. The impurity collecting mechanism includes an impurity removal port 18 opened on the side wall of the air separation box 12, and the impurity removal port 18 is connected to an impurity collection bag 19. Specifically, the impurities blown out by the air blowing mechanism will be sent to the impurity collection bag 19 through the impurity removal port 18 for collection, and each screening component is provided with a corresponding impurity collection mechanism.

[0030] Furthermore, the seed collecting mechanism includes a slide 20 opened at the bottom of the air separation box 12, and a seed collecting box 21 is slidably arranged in the slide 20. A handle 22 is arranged on the seed collecting box 21. Specifically, the seeds passing through the first screening mechanism and the second screening mechanism will fall into the seed collecting box 21. When the seed collecting box 21 needs to be taken out, the door of the air separation box 12 is opened, and the seed collecting box 21 can be pulled out of the slide 20 by the handle 22.

[0031] It can be seen from the above technical scheme that when in use, the seeds are passed into the feed bin 4, and the seeds are passed into the feed box 10 of the first screening mechanism from the multiple feed branch pipes 5 evenly connected at the bottom of the feed bin 4. Here, multiple feed branch pipes 5 are set to make the seeds flow out in a diverted manner to prevent the seeds from being blocked during the feeding process. At this time, the motor 6 is started, and the motor 6 drives the first rotating rod 7 to rotate. The rotation of the first rotating rod 7 drives the second rotating rod 8 to rotate, and at the same time drives the feed box 10 to move back and forth in the through groove 1. Since a filter screen 11 is set at the bottom of the feed box 10, the feed box 10 is in the through groove 1. In the process of moving back and forth, some impurities with larger gravity in the seeds are filtered out, and the seeds are screened for the first time. The screened seeds are passed into the air selection mechanism through the through slot 1, and the air blower 15 is started. The wind is sent into the air supply main pipe 16, and finally the wind is blown out through the two air outlet boxes 17. When the seeds in the air selection box 12 pass through the two screens 14 in turn, the excess impurities mixed in the seeds are sent to the impurity collection bag 19 through the impurity removal port 18 for collection. It should be noted here that the aperture of the upper screen 14 is larger than the aperture of the lower screen 14, which can further improve the screening effect;

[0032] The seeds are screened again by the air selection mechanism, and the screened seeds fall into the seed collecting mechanism arranged at the bottom of the inner cavity of the air selection mechanism. Specifically, the seeds that have passed the first screening mechanism and the second screening mechanism will fall into the seed collecting box 21. When the seed collecting box 21 needs to be taken out, the door of the air selection box 12 is opened, and the seed collecting box 21 is pulled out from the slide 20 through the handle 22. This solves the need to screen crop seeds after harvest, thereby improving the overall seed quality. For the seed air selection device in the prior art, some impurities will fall with the seeds during the air selection process due to their own large gravity, which ultimately leads to poor air selection effect. In addition, there may be a problem of blockage when the seeds are fed.
