[0037] The bottom of the sowing square tube 808 is hingedly mounted with a conical plate 812 on all four sides, the outer wall of the conical plate 812 is mounted with a spring 810, and an angle frame plate 809 is mounted on the end of the spring 810 away from the conical plate 812; the angle frame plate 809 is fixedly mounted on the outer wall of the sowing square tube 808; the outer wall of the angle frame plate 809 is fixedly mounted with a sliding frame 813, and a locking bolt 811 is provided on the inner side of the sliding frame 813 for spiral transmission;

[0038] The bottom of the seed box 2 is fixedly equipped with a fixing frame 3, and a sliding rod 10 is fixedly equipped between the fixing frames 3; the square rod 11 is rotatably installed between the fixing frames 3, and the motor 12 is installed on the outer wall of the fixing frames 3;

[0039] Synchronous cylinders 1 4 are installed at the bottom of both sides of the fixed frame 3, and a movable frame 5 is installed at the bottom end of the bottom of the synchronous cylinder 1 4, and the movable frame 5 is separated from the fixed frame 3; Synchronous cylinders 2 6 are installed at both ends of the inner side of the movable frame 5, and an adjustment frame 7 is installed at the bottom of the synchronous cylinder 2 6, and a limiting groove is opened inside the adjustment frame 7, and the adjustment frame 7 limits the height of the downward pressing square cylinder 807 through the limiting groove;

[0040] A controller 101 is installed on the front side wall of the sowing mobile frame 2, and moving wheels 102 are installed at the four corners of the bottom of the sowing mobile frame 2; the arc frame 801 is slidably restricted outside the slide rod 10, and the sliding frame 813 is slidably restricted on the inner wall of the movable frame 5, and the sliding frame 813 is locked on the movable frame 5 through the locking bolt 811.

[0041] Working principle:

[0042] The interior of the seeding box 2 is designed to store seeds to be sown; the seeds fall into the arc frame 801 through the telescopic seeding tube 9, and the seeding tray 802 in the arc frame 801 is responsible for storing these seeds; when the motor 12 is started, it drives the square rod 11 to rotate, thereby causing the seeding tray 802 to perform a 180° vertical and horizontal flip; this action causes the seeds in the seed cavity to fall vertically into the telescopic supply tube 806, and are transmitted through the tube to the inner side of the sowing square cylinder 808;

[0043] Subsequently, the synchronous cylinder 1 4 is activated to lower the movable frame 5, thereby inserting the conical plate 812 of the sowing square cylinder 808 into the ground; then, the synchronous cylinder 2 6 is activated to lower the adjustment frame 7, thereby pushing the pressing square cylinder 807 to lower inside the sowing square cylinder 808; this action causes the sowing square cylinder 808 to press against the conical plate 812 and extend outward, thereby spreading the soil in the ground;

[0044] Then, the synchronous cylinder 1 4 rises, causing the conical plate 812 to rise out of the ground; the synchronous cylinder 2 6 is started again, causing the sowing square cylinder 808 to rise, thereby canceling the resisting force of the conical plate 812; this causes the spring 810 to rebound, thereby restoring the conical plate 812;

[0045] When the spacing between the plurality of sowing mechanisms 8 needs to be adjusted, the connection between the sliding frame 813 and the movable frame 5 can be loosened by manually rotating the locking bolt 811; in this way, the sowing mechanisms 8 can move along the sliding rod 10, the square rod 11, the movable frame 5 and the adjusting frame 7, so as to adjust the spacing between them;

[0046] The coordinated work of the seeding box 2, the telescopic seeding tube 9, the arc frame 801 and the seeding tray 802 realizes the orderly storage and release of seeds; and the linkage of the motor 12, the square rod 11 and the seeding tray 802 ensures that the seeds can accurately fall into the preset position;

[0047] In addition, through the control of synchronous cylinder 1 4 and synchronous cylinder 2 6, the coordinated action of the sowing square cylinder 808, the conical plate 812 and the downward pressing square cylinder 807 realizes efficient land preparation and creates a good environment for the growth of seeds; and the compression and rebound of the spring 810 ensure that the conical plate 812 can be quickly reset after completing the work, so as to prepare for the next sowing;

[0048] It is worth mentioning that the spacing of the sowing mechanism 8 on the sliding frame 813 can be flexibly adjusted by manually adjusting the locking bolt 811 to adapt to different planting needs and terrain conditions; this high degree of flexibility enables the sowing machine to adapt to a variety of complex environments, thereby improving its practicality and versatility;

[0049] Finally, by rotating the telescopic seed tube 9 and manually adjusting the bidirectional screw 804, quantitative adjustment of the sowing seeds can be easily achieved; this design not only ensures the accuracy of sowing, but also greatly improves the sowing efficiency, bringing great convenience to agricultural production.
