Description

Technical Field

[0001] The utility model relates to the technical field of corn seed production, and more specifically to a precision seeding device for corn seed production. Background Art

[0002] Precision seeding machines are needed in the process of corn seed production. However, the precision seeding machines currently used in corn seed production are relatively large and bulky, inconvenient to carry, and cannot be used for sowing in small areas of land. In addition, although it is precision seeding, there will still be different numbers of seeds in the holes during actual use, and accurate seeding cannot always be guaranteed.

[0003] The existing patent is a precision sowing device for corn seed production. The patent authorization number is CN218451146U. The sowing quantity can be controlled according to demand, and the accuracy of the sowing quantity can be fully guaranteed. The operation is simple and convenient. The seed sowing work can be realized by pulling the baffle plate and releasing the baffle plate.

[0004] However, in the patent authorization number CN218451146U, during the sowing process, it is necessary to manually pull the baffle plate frequently to make the corn seeds fall from the feeding hole. Therefore, the sowing process is not only inefficient, but also increases the labor intensity of the manual labor. Therefore, we propose a precision sowing device for corn seed production to solve the above-mentioned problems. Utility Model Content

[0021] 3. Beneficial effects

[0022] Compared with the prior art, the advantages of the present invention are:

[0023] (1) In this scheme, the transmission shaft drives the rotating disk to rotate through the reduction motor. The corn seeds located on the inner side of the storage bin are discharged through the discharge port and fall into the inner side of the seed groove opened on the edge of the rotating disk. When the seeds in the seed groove move to the feed plate, the feed plate is used to push out the excess seeds on the inner side of the seed groove, so that only one corn seed is retained on the inner side of the seed groove. As the rotating disk continues to rotate, the corn seeds in the seed groove fall through the drop port through the gap opened at the bottom of the retaining ring, thereby realizing the precise sowing of corn seeds, improving the efficiency of the sowing process, and reducing the labor intensity of manual labor.

[0024] (2) In this solution, the assembly hole provided at the rotating disk is connected to the transmission shaft so that the keyway and the cam are matched, and the rotating disk is abutted against the baffle. A hexagonal bolt is installed at the bottom of the transmission shaft so that the nut of the hexagonal bolt abuts against the rotating disk, thereby facilitating the disassembly and assembly of the rotating disk, and the rotating disk with different seed slot sizes can be replaced corresponding to corn seeds of different particle sizes.

[0037] A rotating disk 8 is installed on the inner side of the retaining ring 2, and a seed groove 9 is opened on the edge of the rotating disk 8, and a plurality of seed grooves 9 are arranged at radial positions of the rotating disk 8;

[0038] A reduction motor 11 is installed on the outside of the chassis 1, and a transmission shaft 12 extending to the inside of the chassis 1 is installed at the power output end of the reduction motor 11 through a coupling, and the transmission shaft 12 is transmission-connected to the rotating disk 8, and a baffle 13 that fits with the retaining ring 2 is installed on the outer wall of the transmission shaft 12;

[0039] A notch is provided at the bottom of the retaining ring 2, and a blanking opening 7 is provided at the bottom of the chassis 1 corresponding to the notch;

[0040] The open portion of the chassis 1 is connected with a cover 15 by screws;

[0041] It should be noted that, when the precision seeding device for corn seed production is in use, an appropriate amount of corn seeds is added to the storage bin 4, and then the reduction motor 11 is operated to drive the rotating disk 8 to rotate using the transmission shaft 12, and the corn seeds located inside the storage bin 4 are discharged through the discharge port 5 and fall into the inner side of the seed groove 9 opened at the edge of the rotating disk 8. When the seeds in the seed groove 9 move to the feed plate 3, the feed plate 3 is used to pull out the excess seeds inside the seed groove 9, so that only one corn seed is retained inside the seed groove 9. As the rotating disk 8 continues to rotate, the corn seeds in the seed groove 9 fall through the drop port 7 using the gap opened at the bottom of the retaining ring 2, thereby realizing the precision seeding of corn seeds, improving the efficiency of the sowing process, and reducing the labor intensity of manual labor.

[0042] like Figure 3 As shown, the inner cavity bottom wall of the storage bin 4 is set at an angle, and the angle between the inner cavity bottom wall of the storage bin 4 and the horizontal plane of the bottom of the chassis 1 is 10°;

[0043] It should be noted that the bottom wall of the inner cavity of the storage bin 4 is arranged at an angle, which is conducive to the discharge of the corn seeds located inside the storage bin 4 from the discharge port 5 .

[0045] It should be noted that the provision of the hopper 6 facilitates the addition of corn seeds into the inner side of the storage bin 4 .

[0046] like Figure 4 , Figure 5 , Figure 6As shown, a mounting hole 10 is provided in the middle of the rotating disk 8, and a keyway is symmetrically provided on the inner wall of the mounting hole 10, a transmission shaft 12 is clearance-matched with the mounting hole 10, and a convex key matching with the keyway is symmetrically integrally formed on the outer wall of the end of the transmission shaft 12, a hexagonal bolt 14 is screwed on the end of the transmission shaft 12, and the nut of the hexagonal bolt 14 is in contact with the rotating disk 8;

[0047] It should be noted that, by connecting the assembly hole 10 provided at the rotating disk 8 with the transmission shaft 12, the keyway and the cam are matched, and the rotating disk 8 is abutted against the baffle 13, and by installing the hexagonal bolt 14 at the bottom of the transmission shaft 12, the nut of the hexagonal bolt 14 is abutted against the rotating disk 8, thereby facilitating the disassembly and assembly of the rotating disk 8, and then the rotating disk 8 with different seed slot 9 sizes can be replaced corresponding to corn seeds of different particle sizes.

[0048] like Figure 3 , Figure 5 As shown, a bearing is installed at the junction of the chassis 1 and the transmission shaft 12;

[0049] It should be noted that the friction between the transmission shaft 12 and the chassis 1 is reduced, and the rotation accuracy of the transmission shaft 12 is guaranteed.

[0050] When in use: add an appropriate amount of corn seeds into the storage bin 4, then start the reduction motor 11 to drive the rotating disk 8 to rotate using the transmission shaft 12, and the corn seeds located inside the storage bin 4 are discharged through the discharge port 5 and fall into the inner side of the seed slot 9 opened on the edge of the rotating disk 8. When the seeds in the seed slot 9 move to the material shifting plate 3, the material shifting plate 3 is used to shift out the excess seeds inside the seed slot 9, so that only one corn seed is retained inside the seed slot 9. As the rotating disk 8 continues to rotate, the corn seeds in the seed slot 9 fall through the drop port 7 using the gap opened at the bottom of the retaining ring 2, thereby realizing precise sowing of corn seeds.

[0051] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto.
