[0051] In order to solve the problem that the existing agricultural seeding machine 100 has a low degree of automation and cannot control the spacing between plants during seeding. Figure 1 , Figure 2 , Figures 7 to 11As shown, an agricultural seeder 100 includes a moving mechanism 7 and a sowing mechanism 4. The sowing mechanism 4 includes a support seat 411, a hopper 414, a first driving member 412, and a sowing wheel 413. The support seat 411 is installed on the moving mechanism 7. The specific structure of this moving mechanism 7 can refer to Chinese Patent No. CN201810372078.4, which discloses an automatic corn seeder to realize the movement of the agricultural seeder 100. The first driving member 412 is installed on the support seat 411, and the seeding wheel 413 is installed on the output end of the first driving member 412. The seeding wheel 413 has at least one seeding groove 417. The hopper 414 is installed on the support seat 411, and the hopper 414 is arranged above the seeding wheel 413. The hopper 414 has a discharge port 4141; a material cavity 415 is formed in the hopper 414, and the material cavity 415 is used to store seeds. The seeding wheel 413 has a first moving position and a second moving position. In the first moving position, the seeding groove 417 of the seeding wheel 413 is located below the discharge port 4141 and is connected to the discharge port 4141; in the second moving position, the seeding groove 417 of the seeding wheel 413 is away from the discharge port 4141, and the opening of the seeding groove 417 faces the planting surface;

[0052] Moreover, the calculation formula of the plant spacing of the sowing mechanism is P=S*t; wherein P is the plant spacing, S is the speed of the moving mechanism, and t is the time taken for the sowing wheel to rotate one circle. When there are two sowing grooves 417, the two sowing grooves 417 are respectively arranged at the top and bottom of the sowing wheel 413. At this time, t is the time taken for the sowing wheel 413 to rotate half a circle. The sowing mechanism 4 is driven to move by the moving mechanism 7, and the first driving member 412 of the sowing mechanism 4 is used to drive the sowing wheel 413 to rotate, so that the sowing wheel 413 has a first moving position and a second moving position, and the hopper 414 is used to contain seeds, and the seeds are discharged through the discharge port 4141. When the seeding wheel 413 is in the first moving position, the seeds in the hopper 414 are discharged into the seeding slot 417 through the discharge port 4141, and the seeding wheel 413 drives the seeding slot 417 to move. When the seeding wheel 413 moves to the second moving position, the seeds in the seeding slot 417 fall onto the planting surface through the opening, thereby completing the automatic seeding; in the control of the plant spacing, the relationship between the rotation speed of the first driving member 412 and the moving speed of the moving mechanism 7 can be used to control it. Through the above calculation formula, the plant spacing can be calculated, and the control of the plant spacing is relatively accurate, which improves the problem that the existing agricultural seeding machine 100 has a low degree of automation and cannot control the plant spacing of sowing. The size of this discharge port 4141 and the time when the sowing slot 417 passes through the discharge port 4141 can control how many seeds the discharge port 4141 drops into the sowing slot 417 at one time; that is, the seeding wheel 413 rotates one circle, the sowing slot 417 receives seeds once, and the sowing slot 417 completes one sowing.

[0053] In order to improve the stability of the seeding wheel 413 during seeding. Figures 7 to 11 As shown, the support seat 411 is provided with a sleeve 416, and the sleeve 416 is sleeved on the outside of the seeding wheel 413, and the inner wall of the sleeve 416 is in contact with the outer wall of the seeding wheel 413 and rotates together, and the sleeve 416 is provided with two through openings 418, and the two through openings 418 are arranged opposite to each other; the seeding wheel 413 is in the first moving position, and the seeding groove 417 is connected with the discharge port 4141 through one of the through openings 418; the seeding wheel 413 is in the second moving position, and the seeding groove 417 sows seeds onto the planting surface through the other through opening 418. By sleeve 416 being sleeved on the outside of seeding wheel 413, and two openings 418 being provided on sleeve 416, when first driving member 412 drives seeding wheel 413 to rotate, when seeding wheel 413 rotates from the first moving position to the second moving position, the inner wall of sleeve 416 fits with the outer wall of seeding wheel 413, and sleeve 416 blocks the opening of seeding slot 417, so as to prevent seeds in seeding slot 417 from falling from seeding slot 417 due to the centripetal force of seeding wheel 413, thereby improving the stability of seeding wheel 413 during seeding and preventing seed waste. When seeding wheel 413 is at the first moving position, seeds in hopper 414 fall into seeding slot 417 from discharge port 4141 and one of openings 418; when seeding wheel 413 is at the second moving position, seeds in seeding slot 417 fall onto the planting surface through another opening 418, thereby completing seed sowing.

[0054] In order to improve the sowing efficiency and control the row spacing. Figures 7 to 11 As shown, the sowing mechanism 4 includes a first sowing assembly 41, a second sowing assembly 42, a transmission shaft 43, a hopper 414, and a sowing wheel 413 to form the first sowing assembly 41 or the second sowing assembly 42, the sowing wheel 413 is sleeved on the transmission shaft 43, the transmission shaft 43 is installed on the output end of the first driving member 412, and the first sowing assembly 41 is connected to the second sowing assembly 42 through the transmission shaft 43. The first sowing assembly 41 and the second sowing assembly 42 are connected through the transmission shaft 43. The first driving member 412 drives the transmission shaft 43, which can simultaneously drive the sowing wheels 413 in the first sowing assembly 41 and the second sowing assembly 42 to rotate, so as to realize double-row sowing and improve sowing efficiency; and in terms of controlling the row spacing of sowing, it can be achieved by fixing the distance between the first sowing assembly 41 and the second sowing assembly 42; of course, in this embodiment, multiple groups of sowing assemblies can also be set to realize multi-row sowing.

[0055] In order to realize the automatic sowing of the agricultural seeder 100. Figure 1 and Figure 2As shown, the agricultural seeder 100 also includes a frame 1, a loosening mechanism 2, a furrowing mechanism 3, a first soil covering member 5, and a covering mechanism 6. The frame 1 is installed on a moving mechanism 7, and the loosening mechanism 2, the furrowing mechanism 3, the first soil covering member 5, and the covering mechanism 6 are all installed on the frame 1; the loosening mechanism 2, the furrowing mechanism 3, the sowing mechanism 4, the first soil covering member 5, and the covering mechanism 6 are arranged in sequence on the frame 1. The frame 1 is used to support the loosening mechanism 2, the furrowing mechanism 3, the sowing mechanism 4, the first soil covering member 5, and the covering mechanism 6, so that the moving mechanism 7 drives the loosening mechanism 2, the furrowing mechanism 3, the sowing mechanism 4, the first soil covering member 5, and the covering mechanism 6 to move. During the movement, the loosening mechanism 2 is used to loosen the soil in the field ridge holes, the furrowing mechanism 3 is used to furrow the field ridges after loosening the soil, the sowing mechanism 4 is used to sow in the furrows of the field ridges, the first soil covering member 5 is used to bury the seeds after sowing, and the covering mechanism 6 is used to cover the sown field ridges with film. After the field ridges are covered with the film, the soil remains loose, and the soil aggregates are full of water vapor, which is conducive to the activity of soil microorganisms, accelerates the decomposition of soil organic matter, and provides more soluble nutrients for crops. The loosening of the field ridges, furrowing, sowing, and covering can be realized through the moving mechanism 7. A series of sowing operations.

[0056] In order to further realize the loosening of the soil by the loosening mechanism 2. Figure 3 and Figure 4As shown, the loosening mechanism 2 includes a second driving member 281, a rotating seat 282, and a loosening member 29. The second driving member 281 is installed on the frame 1, the rotating seat 282 is installed on the output end of the second driving member 281, and the loosening member 29 is installed on the rotating seat 282; the loosening member 29 includes a connecting plate 293, at least a first lever 291, and a second lever 292. The middle section of the connecting plate 293 is installed on the bottom of the rotating seat 282, the first lever 291 is installed on the first end of the connecting plate 293, and the second lever 292 is installed on the second end of the connecting plate 293. The loosening mechanism 2 moves with the moving mechanism 7. During the movement, the second driving member 281 drives the rotating seat 282 to rotate, and the first lever 291 and the second lever 292 are inserted into the ridge. The rotation of the rotating seat 282 drives the first lever 291 and the second lever 292 on the connecting plate 293 to rotate. When the first lever 291 and the second lever 292 rotate, they move and loosen the soil on the ridge, thereby realizing the loosening operation. The connecting plate 293 has an adjustment groove 294, which passes from the top to the bottom of the connecting plate 293. The adjustment groove 294 is extended along the length direction of the connecting plate 293. The first lever 291 and the second lever 292 have a connecting hole. One end of the fastener passes through the adjustment groove 294 and the connecting hole at one time and is fixed to the first lever 291 and the second lever 292. The other end of the fastener is against the connecting plate 293. In this way, the position of the first lever 291 and the second lever 292 on the connecting plate 293 can be realized, thereby adjusting the distance between the first lever 291 and the second lever 292, and realizing the adjustment of the loosening range of the loosening piece 29.

[0057] The loosening mechanism 2 also has a lifting assembly 20, which includes a third support structure 21, a fourth driving member 22, a second screw rod 24, a second sliding block 25, and a guide column 23.

The fourth driving member 22 is installed on the support plate 212 and the third supporting plate 213, the second screw rod 24 is installed on the output end of the fourth driving member 22, and the second screw rod 24 is arranged between the second supporting plate 212 and the third supporting plate 213, the second screw rod 24 is arranged parallel to the guide column 23, the second sliding block 25 is sleeved on the outside of the second screw rod 24, the second sliding block 25 is also sleeved on the outside of the guide column 23, and the second sliding block 25 is threadedly matched with the second screw rod 24, the second sliding block 25 is slidably matched with the guide column 23, and the loosening member 29 is installed on the second sliding block 25. The fourth driving member 22 is used to drive the second screw rod 24 to rotate, and friction is generated between the outer wall of the second screw rod 24 and the inner wall of the second sliding block 25. Since the second sliding block 25 is sleeved on the outside of the guide column 23, the guide column 23 is used to limit the moving direction of the second sliding block 25, so that the second sliding block 25 moves along the second screw rod 24, thereby driving the loosening member 29 to move up and down, and adjusting the depth of the loosening member 29 inserted into the field ridge, so that the range of the loosening member 29 when loosening the soil can be adjusted.

[0058] This loosening mechanism 2 also has a support frame 26, fasteners, and a support block 27. The support frame 26 is installed on the second sliding block 25, and the loosening piece 29 is installed on the support block 27.

The fasteners are used to pass through the first mounting hole 261 and the second mounting hole 271 so that the support block 27 is fixed to the support frame 26 through the fasteners. Through the plurality of first mounting holes 261, the lateral position of the loosening piece 29 on the frame 1 can be adjusted to further improve the flexibility of the loosening mechanism 2.

The first sliding block 34 drives the adjustment rod 37 to move, and the adjustment rod 37 drives the mechanical arm 36 to rotate, thereby adjusting the excavation angle and excavation depth between the mechanical arm 36 and the first supporting structure 33. When the excavation angle is large, the angle between the trenching member 38 and the horizontal plane becomes larger, and the excavation resistance of the trenching member 38 becomes larger, but the corresponding excavation depth of the trenching member 38 is deeper, which is suitable for trenches that require deeper depths. When the excavation angle is small, the angle between the trenching member 38 and the horizontal plane becomes smaller, and the excavation resistance of the trenching member 38 becomes smaller, but the corresponding excavation depth of the trenching member 38 is shallower, which is suitable for trenches that require shallower depths.

The second soil retaining plate 52 and the third soil retaining plate 53 are respectively installed on both sides of the first soil retaining plate 51. A soil retaining groove 56 is formed between the inner sides of the first soil retaining plate 51, the second soil retaining plate 52, and the third soil retaining plate 53. The fourth soil retaining plate 55 is installed on the top of the first soil retaining plate 51. The fourth soil retaining plate 55 has spikes 551. The spikes 551 are used to cut and destroy large pieces of soil after contacting with large pieces of soil to increase the air permeability between the soil. The notch 54 is provided on the first retaining plate 51 or the second retaining plate 52 or the third retaining plate 53, and the notch 54 is connected to the retaining groove 56. The first soil covering member 5 moves with the frame 1. Since the first soil covering member 5 is arranged at the rear end of the sowing mechanism 4, after the sowing mechanism 4 sows, the first soil covering member 5 will push the loose soil to move during the movement, and the loose soil will fall into the groove to bury the seeds in the groove; since the first soil covering member 5 has the notch 54, the notch 54 is used to allow the soil in the retaining groove 56 to move out, reduce the soil in the retaining groove 56, and reduce the resistance of the first soil covering member 5 when moving.
