A linkage pipe shaft 9 is slidably sleeved on the top, and the two ends of the linkage pipe shaft 9 are fixedly connected with the third gear 7 and the fourth gear 8 respectively. Limiting grooves are arranged on the side surfaces of the first linkage rotating shaft 14 and the second linkage rotating shaft 16. The limiting blocks are integrally connected on the inner walls of the linkage pipe shaft 9 and the seeding wheel 20, and the limiting blocks are engaged in the limiting grooves. The limiting slide rail 18 can be used to provide support for multiple storage hoppers 19, and the distance between two adjacent storage hoppers 19 can be flexibly adjusted according to usage requirements. Then the third gear 7 and the fourth gear 8 are used to adjust the speed of the first linkage rotating shaft 14. Under the transmission of the synchronous pulley 15, the speed of the second linkage rotating shaft 16 can be effectively adjusted, so that the device can adapt to multi-station sowing operations with different planting spacings, and the operation is flexible and the adaptability is strong.

[0025] Reference Figure 1 , Figure 2A fixed plate seat 12 is fixedly connected to the upper surface of the frame 1, a mounting hole is provided on the outer surface of the fixed plate seat 12, and an adjusting rod 11 is passed through the inside of the mounting hole, one end of the adjusting rod 11 is fixedly connected to a linkage frame 10, one end of the linkage frame 10 is rotatably sleeved on the outside of the linkage tube shaft 9, and two limiting adsorption blocks 13 are fixed to the outside of the adjusting rod 11, and the two limiting adsorption blocks 13 are located on both sides of the fixed plate seat 12. A permanent magnet steel is snap-fitted on the adjacent side surfaces of the two limiting adsorption blocks 13, and a rotating shaft 4 is rotatably installed on the inner side of the frame 1, and a first gear 5 and a second gear 6 are fixed to the outside of the rotating shaft 4, and a third gear 7 cooperates with the second gear 6, and the fourth gear 8 cooperates with the first gear 5. The diameter of the second gear 6 is smaller than the diameter of the first gear 5, and the diameter of the fourth gear 8 is smaller than the diameter of the third gear 7. The rotation of the seeding wheel 20 can be adjusted as needed. During adjustment, the adjusting rod 11 is pulled out, and under the linkage of the linkage frame 10, the linkage pipe shaft 9 slides outside the first linkage rotating shaft 14, so that the third gear 7 is meshed and connected with the second gear 6 or the fourth gear 8 is meshed and connected with the first gear 5. After the adjustment is completed, the corresponding limit adsorption block 13 can be adsorbed on the outer surface of the fixed plate seat 12 to ensure the stability of the transmission.

[0026] Reference Figure 1 , Figure 2 A roller 3 is fixedly installed at both ends of the rotating shaft 4, a universal wheel 22 is rotatably installed on the lower surface of the frame 1, and a handle 2 is fixedly connected to the upper surface of the frame 1, wherein the handle 2, the roller 3 and the universal wheel 22 can be used to enable the device to be flexibly moved on the ground.

[0027] Reference Figure 1 A through groove is provided on the outer surface of the limiting slide rail 18, and a screw is fixedly connected to the side surface of the storage hopper 19. The screw passes through the through groove, and a knob is sleeved on the external thread of the screw. The storage hopper 19 can be limited and fixed by tightening the knob, so that the position adjustment operation of the storage hopper 19 is flexible and convenient.

[0028] Working principle: When in use, first adjust the distance between two adjacent storage hoppers 19 according to the sowing distance. After the adjustment is completed, tighten the knob so that the storage hopper 19 can be effectively fixed on the outside of the limiting slide rail 18, and then pull out one end of the adjusting rod 11. The linkage of the linkage frame 10 can effectively drive the linkage pipe shaft 9 to slide on the outside of the first linkage rotating shaft 14, so that the third gear 7 can be meshed and connected with the second gear 6 or the fourth gear 8 can be meshed and connected with the first gear 5. After the adjustment is completed, the corresponding limiting adsorption block 13 can be adsorbed on the outer surface of the fixed plate seat 12 to ensure the stability of the transmission. Then, the corn seeds to be sown are placed inside the storage hopper 19. At this time, The hand 2 pushes the device to move in the field. During the movement, the roller 3 rolls, which can effectively drive the rotating shaft 4 to rotate. At this time, the first gear 5 or the second gear 6 transfers kinetic energy to the third gear 7 or the fourth gear 8, and then the first linkage rotating shaft 14 starts to rotate. Then, under the linkage of the synchronous pulley 15, the second linkage rotating shaft 16 starts to rotate, and the second linkage rotating shaft 16 drives the seeding wheel 20 to rotate. At this time, the seeding groove 21 on the seeding wheel 20 passes through the discharge port of the storage hopper 19 in sequence. The seeding groove 21 can hold a certain amount of corn seeds. As the seeding wheel 20 continues to rotate, when the seeding groove 21 containing the corn seeds is transferred to the bottom, the corn seeds are sown to the planting point of the land.
