[0034] Reference Figure 1 , Figure 4 and Figure 5The inner wall of the sowing tube 9 is fixedly connected with a fixed disk 12, and the fixed disk 12 is provided with the largest circular hole, and the fixed disk 12 is inclined, so that the seeds in the sowing tube 9 can slide along the inclined surface of the fixed disk 12 to the circular hole. The inner wall of the fixed disk 12 is rotatably connected with a rotating shaft 13, and the outer wall of the rotating shaft 13 is fixedly connected with a circular disk 14, and the circular disk 14 is provided with circular holes of different diameters, and the circular disk 14 is provided with a circular hole of a diameter corresponding to that on the fixed disk 12, so that the circular holes of the circular disk 14 and the fixed disk 12 can be overlapped to adjust the seed sowing amount, refer to Figure 5-Figure 7 The inner wall of the left end of the rotating shaft 13 is elastically connected with a wedge 16 through a positioning spring 15. The wedge 16 is an inclined surface. When squeezed, the wedge 16 will slide along the inner wall of the rotating shaft 13. The inner wall of the left end of the rotating shaft 13 is fixedly connected to one end of the positioning spring 15. When the wedge 16 moves to the left, the positioning spring 15 is compressed. When resetting, the elastic force of the positioning spring 15 is used to reset the wedge 16. The other end of the positioning spring 15 is fixedly connected to the left end of the wedge 16. The wedge 16 is plugged into the inner wall of the fixed disk 12. The inner wall of the fixed disk 12 is provided with a notch, which can allow the wedge 16 to be plugged into it so that the fixed disk 12 and the circular hole on the disk 14 are completely overlapped, and the notch corresponds to the position of the circular hole opened on the disk 14. The disk 14 contacts the bottom end of the fixed disk 12, and the disk 14 contacts the inner wall of the sowing tube 9.

[0035] Reference Figure 1-Figure 3 The limiting mechanism includes a limiting plate 7, which is slidably connected to the inner wall of the connecting block 5. The left end of the limiting plate 7 is fixedly connected to one end of a return spring 6. When the limiting plate 7 moves to the left, the return spring 6 will be compressed. When resetting, the limiting plate 7 is reset by the elastic force of the return spring 6. The other end of the return spring 6 is fixedly connected to the inner wall of the left end of the connecting block 5. The limiting plate 7 passes through and is slidably connected to the inner wall of the connecting block 5. The connecting block 5 is provided with a notch corresponding to the limiting plate 7, which can allow the limiting plate 7 to slide along the inner wall of the connecting block 5. The limiting plate 7 is plugged into the inner side wall of the moving plate 8. The moving plate 8 and the connecting block 5 are provided with a notch, which can allow the limiting plate 7 to be plugged into the notch to limit the position of the entire moving plate 8, and the fixed tube 4 slides with the inner wall of the moving plate 8.

[0036] Working principle: First, when adjusting the position of the sowing tube 9 according to the sowing rows between the land, you only need to move the limit plate 7 to the left to separate the limit plate 7 from the inner side wall notch of the movable plate 8. At this time, the reset spring 6 is in a compressed state, and then move the movable plate 8 downward to allow the inclined groove of the movable plate 8 to squeeze the fixed tube 4, so that the fixed tube 4 with the movable sleeve 3, the sowing tube 9 and the hose 10 will change. According to the adjustment of the actual spacing, the position of the movable plate 8 moving downward is controlled. When the position of the sowing tube 9 needs to be limited, you only need to loosen the limit plate 7 and use the reverse elastic force of the reset spring 6 to reset the limit plate 7, so that the limit plate 7 and the inner side wall notch of the movable plate 8 are plugged together to complete the position adjustment of the entire sowing tube 9. When adjusting again, just follow the above steps.

[0037] When the sowing amount of rice seeds needs to be controlled, it is only necessary to rotate the rotating shaft 13 to rotate the disc 14 and the wedge block 16, and use the inner wall notch of the fixed disc 12 to squeeze the inclined surface of the wedge block 16, so that the wedge block 16 moves to the left and compresses the positioning spring 15, so that the wedge block 16 is separated from the inner wall notch of the fixed disc 12. When the wedge block 16 overlaps with the notch of the fixed disc 12 again, the reverse elastic force of the positioning spring 15 is used to reset the wedge block 16, and the wedge block 16 is inserted into the notch of the inner wall of the fixed disc 12 to position the entire disc 14. At the same time, during the rotation of the disc 14, the circular holes of different diameters on the disc 14 will overlap with the circular holes of the fixed disc 12, and the circular holes of different diameters on the disc 14 will overlap with its circular holes. Due to the different diameters of the circular holes of the disc 14, different numbers of rice seeds will fall, and the position of the disc 14 can be adjusted according to actual needs.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
