Through this structural mode, the walking wheel body 3 adopts a structure in which a rubber ring 9 is sleeved on the outside of the wheel hub 8 and a plurality of rubber plates 10 are used for soft support, so that the walking wheel body 3 as a whole has a certain elastic deformation performance. During the process of sowing by the device, with the auxiliary support of a pair of auxiliary wheels 5 and the first elastic support member 6, it can be better suitable for traveling under load on uneven hilly terrain, and effectively alleviates the phenomenon that the existing sowing device equipped with a traditional fixed structure walking wheel is bumpy and undulating when sowing on hilly terrain, which is not conducive to sowing.

[0027] In this embodiment, the mounting frame 1 is set as a triangular structure, a total of one walking wheel body 3 is provided, and a pair of auxiliary wheels 5 are arranged side by side. One walking wheel body 3 and a pair of auxiliary wheels 5 are arranged in a triangular distribution and assembled on the mounting frame 1. One walking wheel body 3 and a pair of auxiliary wheels 5 are distributed in a triangular structure, which can move as smoothly as possible when sowing in hilly terrain. A push handle 4 is provided at one end of the mounting frame 1 facing the auxiliary wheel 5, and the sowing device can be pushed to sow by holding the push handle 4.
