the seed guide pipe 3 is conical, so that the falling path of the seeds is restricted, the cave forming property of the seeds falling between fields is ensured, the yield can be greatly improved, and the income is increased;
the spring 13 is arranged at the lower end of the push pin shaft 12, and the initial speed of the seeds falling into the seed guide pipe 3 can be increased by utilizing the characteristics of the spring 13, so that the falling time of the seeds is reduced, and the cave forming property of the seeds falling into the fields is enhanced.
The above-described embodiments of the apparatus are merely illustrative, and the units described as separate parts may or may not be physically separate, and parts displayed as units may or may not be physical units, may be located in one place, or may be distributed on a plurality of network units. Some or all of the modules may be selected according to actual needs to achieve the purpose of the solution of the present embodiment. One of ordinary skill in the art can understand and implement it without inventive effort.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
