[0029] The following will be combined with the Figures 1 to 4 This utility model is described in detail, and the technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the embodiments described are only some of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this utility model.

[0030] The utility model provides a corn breeding seeder through improvement. Figure 1 - Figure 4 As shown, the sowing vehicle assembly 1 includes an axle 101, a hopper 102 is fixedly connected to the axle 101, two fixed plates 103 are fixedly connected to the hopper 102, and a picking assembly 2 for picking up seeds is provided between the two fixed plates 103;

[0031] The pickup assembly 2 includes two circular plates 201, between which an arc-shaped plate 202 and a filter screen 204 are fixedly connected, a horizontal plate 203 is fixedly connected between the two circular plates 201, and a fan 205 is fixedly connected to the horizontal plate 203. A fixed rod 206 is fixedly connected between one of the circular plates 201 and the fixed plate 103. The two circular plates 201 are rotatably connected to the same rotating sleeve 207, and the rotating sleeve 207 is provided with a plurality of through holes 208. The rotating sleeve 207 is provided with a quantity adjustment assembly 3 for adjusting the number of adsorbed seeds. The lower end of the axle 101 is fixedly connected to a furrow opener 6 for cultivating soil, and the side wall of the hopper 102 is fixedly connected to a seed discharge bucket 7 for discharging seeds.

[0032] In this embodiment: when the seeding vehicle assembly 1 moves, the axle 101 drives the protective shell 302 to rotate through the transmission assembly 4, so that the protective shell 302 drives the rotating sleeve 207 to rotate through multiple movable shafts 301, and since the circular plate 201 is fixedly connected to the fixed plate 103 through the fixing rod 206, the circular plate 201 will not rotate. When the fan 205 is started, the airflow generated by the fan 205 can enable the through-hole 208 on the lower side of the horizontal plate 203 to adsorb corn seeds. In this process, when the corn seeds are adsorbed into the through-hole 208, the corn seeds will block the through-hole 208, so that this through-hole 208 can no longer adsorb other seeds, thereby realizing the function of a single through-hole 208 that can only adsorb one corn seed. When the through-hole 208 for adsorbing seeds rotates to the upper side of the horizontal plate 203, the corn seeds can be blown out under the air pressure of the fan 205 and discharged into the soil ditch opened by the furrow opener 6 through the seed bucket 7.

[0033] In the above embodiment, in order to adjust the number of seeds dropped each time, the following method can be used:

[0034] The quantity adjustment component 3 includes a plurality of movable shafts 301 rotatably connected to the rotating sleeve 207. The movable shafts 301 are provided with a plurality of air holes matching the through holes 208. The plurality of movable shafts 301 are rotatably connected to the same protective shell 302. A threaded rod 303 is rotatably connected to one side wall of the rotating sleeve 207. The threaded rod 303 is threadedly connected to the protective shell 302. The end of the threaded rod 303 away from the rotating sleeve 207 is fixedly connected to a turntable 304. The ends of the plurality of movable shafts 301 away from the protective shell 302 are rotatably connected to the rotating sleeve 207. With the same annular plate 305, a transmission assembly 4 for driving the rotating sleeve 207 to rotate is fixedly connected to the protective shell 302, and a spacing adjustment assembly 5 for simultaneously driving the rotation of multiple movable shafts 301 is installed inside the protective shell 302. The transmission assembly 4 includes a fixed frame 401 fixedly connected to the protective shell 302, and a square telescopic rod 402 is fixedly connected to the fixed frame 401. The square telescopic rod 402 is rotatably connected to the fixed plate 103, and a pulley group 403 is installed between the square telescopic rod 402 and the axle 101.

[0035] In a preferred embodiment, by rotating the turntable 304, the threaded rod 303 drives the protective shell 302 to move, and the protective shell 302 drives multiple movable shafts 301 to move, so that the movable shaft 301 can block the through hole 208 in the same row, thereby making the blocked through hole 208 unable to adsorb corn seeds, thereby realizing the function of adjusting the number of seeds discharged each time. In addition, when the sowing vehicle assembly 1 moves, the axle 101 and the pulley group 403 can drive the square telescopic rod 402 to rotate, and the square telescopic rod 402 drives the protective shell 302 through the fixed frame 401, and then can automatically drive the rotating sleeve 207 to rotate when the sowing vehicle assembly 1 moves, thereby realizing the function of automatic sowing of seeds at equal intervals.

[0036] refer to Figure 4 In a preferred embodiment, the spacing adjustment component 5 includes multiple first gears 501, and the number of the first gears 501 is half of the movable shaft 301. The multiple first gears 501 are respectively fixedly connected to the movable shaft 301, and the multiple first gears 501 are arranged at intervals. A main gear 502 meshing with the multiple first gears 501 is rotatably connected to the protective shell 302, and a second gear 503 meshing with the main gear 502 is rotatably connected to the side wall of the protective shell 302. A rotating block 504 is fixedly connected to the second gear 503.

[0037] In this embodiment, by rotating the rotating block 504, the rotating block 504 can drive the main gear 502 to rotate through the second gear 503, and the main gear 502 can drive multiple first gears 501 to rotate, thereby driving half of the movable shaft 301 to rotate, so that half of the through holes 208 cannot take in or out air, thereby increasing the sowing spacing and playing a role in regulating the sowing spacing.

[0038] It is worth noting that since the main gear 502 can drive multiple movable shafts 301 to rotate simultaneously, the resistance to the rotation of the main gear 502 is relatively large. Therefore, under normal circumstances, the main gear 502 can be fixed by relying on the friction between the multiple movable shafts 301 and the rotating sleeve 207.

[0039] Working principle: When in use, first, the staff drives the vehicle to pull the seeding vehicle assembly 1 to move. During this process, the square telescopic rod 402 can be driven to rotate through the axle 101 and the pulley group 403. The square telescopic rod 402 drives the protective shell 302 to rotate through the fixed frame 401, so that the protective shell 302 drives the rotating sleeve 207 to rotate through multiple moving shafts 301. Since the circular plate 201 is fixedly connected to the fixed plate 103 through the fixed rod 206, the circular plate 201 will not rotate. When the fan 205 is started, it can generate The airflow enables the through-holes 208 on the lower side of the horizontal plate 203 to absorb the corn seeds inside the hopper 102. In this process, when the corn seeds are absorbed into the through-holes 208, the corn seeds will block the through-holes 208, making it impossible for the through-holes 208 to continue to absorb other seeds, thereby achieving the function of a single through-hole 208 to absorb only one corn seed. When the through-holes 208 for absorbing seeds rotate to the upper side of the horizontal plate 203, the corn seeds can be blown out under the air pressure of the fan 205 and discharged into the soil trench opened by the furrow opener 6 through the seed discharging bucket 7.

[0040] When the number of seeds to be sown needs to be adjusted, the staff first rotates the turntable 304, so that the threaded rod 303 drives the protective shell 302 to move, and the protective shell 302 drives the multiple movable shafts 301 to move, so that the movable shafts 301 can block the through holes 208 in the same row. The more through holes 208 are blocked, the fewer seeds are sown.

[0041] When the seed spacing needs to be adjusted, the staff rotates the rotating block 504 so that the rotating block 504 can drive the main gear 502 to rotate through the second gear 503, and the main gear 502 drives multiple first gears 501 to rotate, and then can drive half of the movable shaft 301 to rotate, so that half of the through holes 208 cannot take in or out air, thereby increasing the sowing spacing. Conversely, the spacing can be reduced.

[0042] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
