[0022] When specific implementation, agricultural seeding machine is important equipment in modern agricultural production, its use can greatly improve seeding efficiency and crop yield, traditional agricultural seeding machine is difficult to adjust seeding spacing, leading to seeding spacing is difficult to adjust according to actual conditions, can push seeding pipe 5 to the direction close to the inside of plastic card seat 12, when seeding pipe 5 moves to the inside of plastic card seat 12, plastic card seat 12 end can extrude deformation, when seeding pipe 5 completely moves to the inside surface of plastic card seat 12, seeding pipe 5 can be clamped in the inside of plastic card seat 12, and rubber protrusion 13 will be extruded and deformed by seeding pipe 5, at this time, seeding pipe 5 can be installed in the inside of plastic card seat 12, the distance between the bottom of seeding pipe 5 and ground can be adjusted by pulling seeding pipe 5 to slide in the inside of plastic card seat 12, when seeding pipe 5 is pulled, corrugated hose 14 can be compressed or stretched, when two groups of seeding pipe 5 are fixed, screw rod 8 can be positively rotated, when screw rod 8 is positively rotated, two groups of sliding block 9 can be driven to threadedly slide away from each other, when sliding block 9 threadedly slides, connecting rod 11 can be driven to move, when connecting rod 11 moves, plastic card seat 12 and seeding pipe 5 can be driven to move.

[0023] Refer to Figures 1-3 When two groups of seeding pipe 5 move away from each other to specified position, the spacing between two groups of seeding pipe 5 can be adjusted at this time, so that seeding spacing can be adjusted accordingly, at this time, seeding spacing increases, on the contrary, screw rod 8 can be reversed, so that two groups of seeding pipe 5 can be driven to move close to each other, so that seeding spacing decreases, through the above mode, the seeding spacing between two groups of seeding pipe 5 can be adjusted simply and conveniently according to actual conditions, so as to improve the practicability of agricultural seeding machine.

[0024] Refer toFigure 1 , Figure 2 and Figure 4 It is known that a box body 16 is installed inside the storage box 2, and a forward and reverse motor 17 is installed inside the box body 16. The output end of the forward and reverse motor 17 is connected to the box body 16 via a bearing and a rotating shaft 18. A gear 19 is welded to the outside of the rotating shaft 18. A first rack 20 and a second rack 21 are respectively meshed on the outside of the gear 19. A sealing block 22 is connected to the outside of the box body 16 near the first rack 20 and the second rack 21. A stop block 23 is connected to the bottom of the first rack 20 and the second rack 21. The first rack 20 and the second rack 21 form a sliding structure with the box body 16. The size of the stop block 23 matches the size of the discharge pipe 4.

[0025] In practice, the seed discharge speed of agricultural seeders is usually fixed during use, making it difficult to control the seed discharge speed according to the actual situation. This can lead to excessive seed discharge and waste. To address this, the forward and reverse motor 17 can be activated. When the forward and reverse motor 17 reverses, it drives the rotating shaft 18 to reverse as well. When the rotating shaft 18 reverses, it drives the gear 19 to reverse as well. When the gear 19 reverses, it meshes with and moves the first rack 20 and the second rack 21 towards the corresponding discharge pipe 4. As the first rack 20 and the second rack 21 move, they slide against the sealing block 22. Simultaneously, during their movement, the first rack 20 and the second rack 21 drive the corresponding stop block 23 towards the end of the corresponding discharge pipe 4. When the end of the stop block 23 reaches a designated position above the end of the discharge pipe 4, the stop block 23 can block the end of the discharge pipe 4, thereby reducing the seed discharge speed.

[0026] See Figure 1 , Figure 2 and Figure 4 It can be seen that by controlling the position of the stop block 23, the discharge speed of crop seeds can be controlled, so that the crop seeds are less likely to be discharged in excess, thereby reducing the waste caused by excessive discharge of crop seeds.

[0027] In summary, when using the adjustable agricultural seeding machine, the seeding tube 5 can be pushed towards the inside of the plastic holder 12, when the seeding tube 5 moves to the inside of the plastic holder 12, the end of the plastic holder 12 can be extruded and deformed, the lead screw 8 can be reversed to drive the two groups of seeding tubes 5 to move close to each other, so that the seeding interval is reduced, through the above method, the seeding interval between the two groups of seeding tubes 5 can be adjusted simply and conveniently according to the actual situation, thereby improving the practicability of the agricultural seeding machine, when the end of the stop block 23 moves to the specified position above the end of the discharge pipe 4, the stop block 23 can shield the end of the discharge pipe 4, thereby reducing the discharge speed of the crop seeds, by controlling the position of the stop block 23, the discharge speed of the crop seeds can be controlled, so that the crop seeds are not easy to discharge too much, thereby reducing the waste of crop seeds caused by excessive discharge, the contents not described in detail in the description belong to the prior art known to those skilled in the art.

[0028] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
