[0026] The discharging assembly 5 also includes a restraining unit 52, which includes a threaded sleeve 521, which is fixedly connected to the upper surface of the connecting slider 513, the inner wall of the threaded sleeve 521 is threadedly connected with an extrusion bolt 522, and the lower surface of the extrusion bolt 522 is provided with a pressure plate 523. The inner wall of the inner discharging hopper 511 is located at the limiting slide groove 512 and is fixedly connected with a damping strip 524, the pressure plate 523 abuts against the upper surface of the damping strip 524, and a storage cavity 525 is opened on the lower surface of the connecting slider 513, and the threaded sleeve 521 is communicated with the inner wall of the storage cavity 525.

[0027] Specifically, there are three inner discharge hoppers 511, which are arranged vertically with respect to the fuselage 2. The number of outer hoppers 514 matches that of the inner discharge hoppers 511. By installing the outer hoppers 514 on the outside of the inner discharge hoppers 511, the fallen seeds can be smoothly received after extension, thereby improving the smoothness of the seeds when they fall and reducing the drop of the connecting part which is inside and easily causes the seeds to get stuck.
