DETAILED DESCRIPTION

[0019] In order to enable personnel in the technical field to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work should belong to the scope of protection of the present application.

[0020] Please refer to Figures 1 to 6 The present application provides a seed selection and treatment device for agricultural cultivation, which comprises two groups of support frames 1, a screening box 2 is rotatably connected to the support frame 1 through a connecting shaft, a screen 3 is rotatably connected in the screening box 2, a screening mechanism 4 is rotatably connected to the center of the inside of the screening box 2, the screening mechanism 4 is used for screening and discharging impurities, a feed inlet 5 is fixedly connected to the upper end of one side of the screening box 2, a fan is arranged at the end of the screening box 2 away from the feed inlet 5, an air inlet pipe 6 is fixedly connected to the end of the screening box 2 close to the feed inlet 5, and a lifting mechanism 7 is slidably connected to one of the support frames 1.

[0021] The screening mechanism 4 can drive the seeds in the screening box 2 to continuously move, the fan can separate the shells and light impurities from the seeds, and the shells and light impurities can be discharged from the screening box 2, so that the selection of the seeds is completed. The lifting mechanism 7 can drive the screening box 2 to tilt. When the shells and light impurities in the seeds are too much, the screening box 2 can be kept in a horizontal state for a long time, so that the seeds can be continuously screened, and the shells and light impurities can be removed more completely. When the screening is completed, the screening box 2 is tilted, the screened seeds can be discharged from the screening box 2, and the seeds can be collected. When the shells and light impurities are less, the angle of the screening box 2 is controlled by the lifting mechanism 7 to tilt, so that the seeds can continuously enter from the feed inlet 5. When the seeds move to the end of the screening mechanism 4, the shells and light impurities can be separated from the seeds, the screening operation can be continuously performed, and the work efficiency is improved.

[0022] See also Figures 3 to 5 The screening mechanism 4 includes a rotating tube 8 rotatably connected to the inner wall of the screening box 2, a storage slot 9 is opened on the rotating tube 8, a first baffle 10 is fixedly connected to the outer wall of the rotating tube 8, a second baffle 11 is fixedly connected to the outer wall of the rotating tube 8 close to the first baffle 10, and a fixed rod 12 is symmetrically fixedly connected to the outer wall of the rotating tube 8 away from the first baffle 10, and an end of the fixed rod 12 away from the rotating tube 8 is fixedly connected to an arc rod 13, one end of the rotating tube 8 is rotatably connected to a first discharge pipe 14, and the end of the rotating tube 8 close to the first discharge pipe 14 is fixedly connected to a rotating rod 15. A rotating handle 16 is fixedly connected to the side of the screening box 2 close to the rotating rod 15, and the rotating handle 16 is fixedly connected to the rotating rod 15. The outer surface of the rotating tube 8 is fixedly connected to a first partition plate 17, and the first partition plate 17 is fixedly connected to the end of the first baffle 10 away from the feed port 5. The inner wall of the screening box 2 close to the screen 3 is fixedly connected to a second partition plate 33, and the side of the second partition plate 33 close to the arc rod 13 is fixedly connected to a second discharge pipe 18. The side of the screening box 2 away from the rotating handle 16 is fixedly connected to a motor 19, and the output end of the motor 19 is fixedly connected to the screen 3 through a connecting rod.

[0023] When the seeds enter the screen 3, the motor 19 is started, and the motor 19 drives the screen 3 to rotate through the connecting rod, and the rotation of the screen 3 drives the seeds to move. When the seeds come into contact with the arc rod 13, the arc rod 13 separates the seeds from the screen 3 and puts them in the air. The space between the shell, light impurities and the seeds increases, so that the flowing air drives the shell, light impurities and the like to separate from the seeds, so that the shell, light impurities and the like enter the second baffle 11 and move along the inclined second baffle 11 to the storage tank 9. The flowing air will drive the shell, light impurities and the like to be discharged from the first discharge pipe 14, thereby realizing the separation of the shell, light impurities and the like from the seeds. When the box 2 is tilted, the screen 3 is tilted synchronously. At this time, the seeds will roll along the tilted screen 3. The seeds that have completed screening will be discharged from the screening box 2 through the second discharge pipe 18. When the impurities such as shells in the seeds are large and heavy, the rotating handle 16 is rotated. The rotation of the rotating handle 16 drives the rotating rod 15 to rotate. The rotation of the rotating rod 15 drives the rotating tube 8 to rotate. The rotation of the rotating tube 8 drives the first baffle 10 and the second baffle 11 to rotate, so that the second baffle 11 is closer to the bottom end of the screen 3. When the fan power is constant, the larger and heavier impurities such as shells can smoothly enter the second baffle 11, and then be discharged from the first discharge pipe 14, reducing energy consumption.

[0024] See also Figure 2 、 Figure 3 and Figure 6The lifting mechanism 7 comprises a sliding sleeve rod 20 connected to the support frame 1, a sliding groove 21 is formed in the sliding sleeve rod 20, a connecting rod 22 is slidably connected in the sliding groove 21, the connecting rod 22 is fixedly connected with the support frame 1 in the sliding sleeve rod 20, one end of the sliding sleeve rod 20 is fixedly connected with a support seat 23, a connecting groove 24 is formed in the support seat 23, a threaded rod 25 is rotatably connected in the connecting groove 24, one end of the threaded rod 25 is fixedly connected with a first bevel gear 26, one side of the support seat 23 close to the first bevel gear 26 is rotatably connected with a rotating shaft 27, the rotating shaft 27 is fixedly connected with a second bevel gear 28, the second bevel gear 28 is engaged with the first bevel gear 26, one end of the rotating shaft 27 extending out of the support seat 23 is fixedly connected with a handle 29.

[0025] Please refer to Figure 2 A sliding block 30 is threadedly connected on the threaded rod 25, and the sliding block 30 is fixedly connected with the connecting rod 22.

[0026] When the screening box 2 needs to be tilted, the handle 29 is rotated, the handle 29 drives the rotating shaft 27 to rotate, the rotating shaft 27 drives the second bevel gear 28 to rotate, the second bevel gear 28 drives the first bevel gear 26 to rotate, the first bevel gear 26 drives the threaded rod 25 to rotate, the threaded rod 25 drives the sliding block 30 to move, the sliding block 30 drives the connecting rod 22 to move, the connecting rod 22 drives the support frame 1 to move, and the support frame 1 drives one side of the screening box 2 to rotate relative to the support frame 1, so that the screening box 2 is tilted, and the seeds are discharged from the second discharge pipe 18 out of the screening box 2. The threaded rod 25 and the sliding block 30 can be locked by a locking structure (such as a bidirectional wedge-shaped block mechanical lock) to avoid reverse rotation of the threaded rod 25 when adjusted to the position. The corresponding locking structure is very perfect, and will not be described in detail here.

[0027] Please refer to Figure 5 A communication port 31 is formed in the rotating pipe 8, the communication port 31 is communicated with the storage groove 9, one side of the communication port 31 is fixedly connected with the first baffle 10, and the other side of the communication port 31 is fixedly connected with the second baffle 11. The shells, light impurities and the like entering the second baffle 11 move along the second baffle 11 to the communication port 31, and then move to the storage groove 9 through the communication port 31, so that the flowing air drives the shells, light impurities and the like to the first discharge pipe 14 and is discharged.

[0028] Please refer to Figure 3 A guide plate 32 is fixedly connected to the inner wall below the feeding port 5 of the screening box 2, and one side of the guide plate 32 close to the screen 3 is inclined. The seeds entering from the feeding port 5 fall on the guide plate 32 and move to the screen 3 through the guide plate 32 for screening.

[0029] Please refer to Figure 3 and Figure 5 The arc-shaped rod 13 is in abutment with the screen 3, and the side of the arc-shaped rod 13 away from the screen 3 is arranged in an inclined manner. The arc-shaped rod 13 arranged in an inclined manner can make the seeds more easily be carried into the air, so that the seeds and the shells, light impurities and the like are separated. The seeds in the same row of the arc-shaped rod 13 can be carried into the air in sequence, so that the seeds and the shells, light impurities and the like are further separated, and the excessive seeds and the shells, light impurities and the like in the same time are avoided, so that the seeds and the shells, light impurities and the like are difficult to separate due to mutual extrusion.

[0030] Please refer to Figure 3 and Figure 5 The first baffle 10 is in abutment with the inner wall of the screen 3, the width of the second baffle 11 is smaller than the width of the first baffle 10, and there is a certain included angle between the first baffle 10 and the second baffle 11.

[0031] There is a certain included angle between the first baffle 10 and the second baffle 11, so that the shells, light impurities and the like can enter the second baffle 11 and be blocked by the first baffle 10, so as to ensure that the shells, light impurities and the like move to the storage groove 9 through the communication port 31.

[0032] Please refer to Figure 4 The first discharge pipe 14 and the second discharge pipe 18 are arranged in an interlaced manner, and the pipe openings of the first discharge pipe 14 and the second discharge pipe 18 are opposite to each other, so that the seeds and the shells, light impurities and the like after screening can be discharged in a staggered manner, so as to avoid mixing together again on the same side.

[0033] Please refer to Figure 3 The air inlet pipe 6 is located on the side of the screening box 2 close to the first baffle 10, and the first baffle 10 is in abutment with the screen 3, so that the air flowing from the air inlet pipe 6 flows around the first baffle 10 from the lower side of the first baffle 10, so that the flowing air carries the shells, light impurities and the like in the air to the second baffle 11, so as to screen the seeds.
