[0002] Millet is a kind of plant belonging to the family of Poaceae, an annual herb, and its fruit is commonly known as millet after peeling, and it is also called Ji, Su and Lang in ancient times. Seeding is one of the basic links in agricultural production, and the quality of seeding directly affects the emergence and growth of crops.

[0061] Embodiment 1:

[0062] As Figures 1-3As shown, the embodiment provides a millet seeder, which comprises a frame 1, the tail end of the frame 1 is provided with a handrail 11, the frame 1 is sequentially connected from front to back with a rotating shaft 2, a seed storage bin 12 and a press wheel 13, the rotating shaft 2 is connected with two wheels 21;

[0063] The rotating shaft 2 is respectively provided with a plurality of first connecting positions at both ends, and the wheel 21 is connected with any first connecting position;

[0064] The outlet of the seed storage bin 12 is communicated with a particle size regulating assembly 3, and the particle size regulating assembly 3 is communicated with a quantity regulating assembly 4;

[0065] The frame 1 is slidably connected with a lifting cylinder 5, the lifting cylinder 5 is arranged corresponding to the outlet of the quantity regulating assembly 4, and the lifting cylinder 5 is drivingly connected with the quantity regulating assembly 4;

[0066] The lifting cylinder 5 is penetratingly provided with a connecting cylinder 6, the connecting cylinder 6 is provided with a plurality of second connecting positions, the lifting cylinder 5 is connected with any second connecting position, and the bottom of the connecting cylinder 6 is provided with a seeding duckbill 61;

[0068] The rotating shaft 2 is provided with a driving wheel set 8, and the driving wheel set 8 is drivingly connected with the particle size regulating assembly 3 and the speed change system 71 respectively.

[0069] It can be understood that during the sowing process, the staff pushes the two wheels 21 to rotate through the handrails 11, the wheels 21 drive the rotating shaft 2 to rotate, the rotation of the rotating shaft 2 applies driving force through the driving wheel set 8, the driving wheel set 8 is connected with the particle size control assembly 3, so that the millet seeds in the seed storage bin 12 gradually enter the particle size control assembly 3 for particle size sorting, and the millet seeds with a particle size within the sowing range enter the quantity control assembly 4 for sowing; the driving wheel set 8 is connected with the speed change system 71, drives the driving disc 72 to rotate, the driving disc 72 drives the lifting cylinder 5 to reciprocate up and down through the connecting rod assembly 73, when the lifting cylinder 5 rises, the driving quantity control assembly 4 discharges a set number of millet seeds, the set number of millet seeds enter the bottom of the connecting cylinder 6 from the lifting cylinder 5, when the lifting cylinder 5 descends, the pushing connecting cylinder 6 is embedded into the soil, after the single-row sowing is completed, the wheel 21 located on one side carries out the next row sowing along the wheel mark of the wheel 21 located on the other side, so that the sowing row distance of the millet is equal to the distance between the two wheels 21, with the continuous rotation of the pushing wheel 21, the process of embedding the connecting cylinder 6 for sowing and discharging the set number of millet seeds from the quantity control assembly 4 is repeatedly carried out, and the precision sowing of the millet with a set particle size range, a set number, a set depth, a set plant distance and a set row distance is realized; and the particle size range can be controlled through the particle size control assembly 3; the sowing number can be controlled through the quantity control assembly 4; the sowing depth can be adjusted by adjusting the connection between the lifting cylinder 5 and the second connecting position; the sowing plant distance can be adjusted by adjusting the rotation circle number ratio of the rotating shaft 2 and the driving shaft 7 through the speed change system 71, and the rotation circle number ratio of the wheel 21 and the lifting cylinder 5; and the sowing row distance can be adjusted by adjusting the connection between the wheel 21 and the first connecting position.

[0070] It should be noted that the speed change system 71 includes a derailleur type speed change system, which is in transmission connection with the second sprocket 86 of the driving wheel set 8 through a second chain.

[0071] As shown in Figures 4-5 the driving wheel set 8 includes a butt joint cylinder 81, an adjusting cylinder 82 and a positioning cylinder 83, a plurality of gears 22 are arranged on the rotating shaft 2, a plurality of tooth rings 84 are arranged in the butt joint cylinder 81, and the tooth rings 84 are in meshing connection with the gears 22.

[0072] A first sprocket 85 and a second sprocket 86 are arranged on the outer wall of one end of the butt joint cylinder 81, the first sprocket 85 is in transmission connection with the particle size control assembly 3, and the second sprocket 86 is in transmission connection with the speed change system 71.

[0073] The other end of the butt joint cylinder 81 is rotationally connected in the adjusting cylinder 82 through a bearing 87, the adjusting cylinder 82 is slidingly arranged in the positioning cylinder 83, and the positioning cylinder 83 is fixedly connected with the rack 1.

[0074] A reset spring 88 is arranged between the adjusting cylinder 82 and the positioning cylinder 83, and the adjusting cylinder 82 is connected with a regulating mechanism 89 for regulating the engagement and disengagement of the tooth ring 84 and the gear 22.

[0075] It can be understood that the rotation of the two wheels 21 drives the driving wheel set 8 to drive the granularity regulating assembly 3 and the lifting cylinder 5 to operate, and the lifting cylinder 5 drives the connecting cylinder 6 to embed into the sowing and quantity regulating assembly 4 to discharge millet seeds, so that the millet sower is always in a sowing state and cannot be switched between the sowing state and the moving state. Therefore, the driving wheel set 8 is arranged to include the docking cylinder 81, the adjusting cylinder 82 and the positioning cylinder 83. When sowing, the reset spring 88 limits the position of the adjusting cylinder 82 in the positioning cylinder 83, so that the tooth ring 84 and the gear 22 are kept in the engaged state. When the two wheels 21 rotate to drive the rotating shaft 2 to rotate, the first sprocket 85 and the second sprocket 86 rotate with the rotating shaft 2 through the engagement of the tooth ring 84 and the gear 22, the first sprocket 85 drives the granularity regulating assembly 3 to operate, and the second sprocket 86 drives the lifting cylinder 5 to operate, so that the millet sower is in the sowing state. When sowing is completed or when turning in the planting ground, the adjusting cylinder 82 is driven to slide in the positioning cylinder 83 through the regulating mechanism 89, the adjusting cylinder 82 presses and contracts the reset spring 88, and after the adjusting cylinder 82 slides in place in the positioning cylinder 83, the tooth ring 84 and the gear 22 are disengaged. After the tooth ring 84 and the gear 22 are disengaged, the first sprocket 85 and the second sprocket 86 no longer rotate with the rotating shaft 2, and the granularity regulating assembly 3 and the lifting cylinder 5 stop operating, so that the millet sower is in the moving state. After the regulating mechanism 89 is adjusted back, the millet sower enters the sowing state again.

[0077] It can be understood that when the brake handle 892 is gripped, the brake handle 892 drives the adjusting cylinder 82 to slide in the positioning cylinder 83 through the brake cable 891, the adjusting cylinder 82 presses and contracts the reset spring 88, and after the adjusting cylinder 82 slides in place in the positioning cylinder 83, the tooth ring 84 and the gear 22 are disengaged. After the tooth ring 84 and the gear 22 are disengaged, the first sprocket 85 and the second sprocket 86 no longer rotate with the rotating shaft 2, and the granularity regulating assembly 3 and the lifting cylinder 5 stop operating, so that the millet sower is in the moving state. When the brake handle 892 is released, the adjusting cylinder 82 slides in the positioning cylinder 83 to reset under the action of the reset spring 88, and the tooth ring 84 and the gear 22 return to the engaged state.

[0078] As shown in Figure 5As shown, the two ends of the rotating shaft 2 are arranged with a plurality of threaded holes 23, and the middle position of the wheel 21 is arranged with a limiting cylinder 24, which is in clearance fit with the rotating shaft 2. The limiting cylinder 24 is connected with the threaded holes 23 through bolts. A plurality of ground gripping cones 25 are arranged on the wheel 21, which are used to enhance the ground gripping force and mark the sowing path.

[0079] It can be understood that the ground gripping force of the wheel 21 is enhanced by the ground gripping cone 25, and at the same time, the wheel 21 leaves clear wheel marks after rotating on the sowing land, so that after the single-row sowing is completed, the wheel 21 located on one side can follow the wheel marks of the wheel 21 located on the other side for the next row sowing. The plurality of threaded holes 23 arranged at the two ends of the rotating shaft 2 enable the limiting cylinder 24 to be connected at a plurality of positions on the rotating shaft 2, so as to facilitate the adjustment of the distance between the wheel 21 and the connecting cylinder 6, cooperate with the next row sowing along the wheel marks, and realize the adjustment of the sowing row distance.

[0080] As shown in the figure, Figures 6-7 The particle size regulating assembly 3 includes a box body 31, a sieve plate 32 and a discharging shaft 33. The top end of the box body 31 is provided with a feeding passage 34, which is in communication with the outlet of the seed storage bin 12.

[0084] It should be noted that the first sprocket 85 is in transmission connection with the third sprocket 36 through the first chain.

[0085] It can be understood that when the rotating shaft 2 drives the driving wheel set 8 to rotate, the first sprocket 85 of the driving wheel set 8 drives the third sprocket 36 to rotate through the first chain, and the number of teeth of the third sprocket 36 is less than the number of teeth of the first chain, so that one rotation of the first chain can drive the third sprocket 36 to complete multiple rotations; when the third sprocket 36 rotates, the plurality of baffles 35 on the feeding shaft 33 rotate in the feeding channel 34, and through the rotation of the plurality of baffles 35, the millet seeds in the seed storage bin 12 gradually enter the box body 31, avoiding the accumulation of millet seeds in the box body 31; after the millet seeds enter the box body 31, they enter the collection groove, the collection groove guides the millet seeds to arrange into a plurality of guide grooves 321, and the millet seeds roll on the sieve plate 32 from top to bottom along the guide grooves 321; since the guide grooves 321 are provided with ladder-shaped holes 322 with a narrow top and a wide bottom, the ladder-shaped holes 322 are used for size screening of the millet seeds rolling in the guide grooves 321; millet seeds with a small size enter the small-size groove 37 through the ladder-shaped holes 322 at the front end of the guide groove 321, millet seeds with a suitable size range enter the seeding groove 38 at the middle of the guide groove 321, and millet seeds with a large size enter the large-size groove 39 at the tail end of the guide groove 321; the millet seeds in the seeding groove 38 are seeded after entering the number control assembly 4, and the millet seeds in the small-size groove 37 and the large-size groove 39 are taken out and recycled.
