[0002] Most of the world's rice production is distributed in the monsoon areas of East Asia, Southeast Asia, and South Asia, and the tropical rainforest areas of Southeast Asia. Rice cultivation has a long history. China is the world's largest rice producer, and rice is the main food loved by local people.

[0003] In the initial stage of rice planting, it is generally necessary to use a sowing device to sow rice. Traditional sowing devices are inconvenient to use. The distance between the running wheels on both sides of the sowing box is generally fixed and cannot be adjusted. Since the width of the ridges used to plant rice in different rice fields is sometimes different, the traditional sowing device is used to sow in different rice fields. It is easy for the running wheels to press on the ridges when walking, thereby affecting the rice sowing effect. Its applicability is relatively poor and its use is relatively inconvenient. Therefore, it is necessary to propose an improvement measure to solve the above technical problems.

[0004] It should be noted that the above contents belong to the technical cognition scope of the inventor. Since the technical contents in this field are vast and too complicated, the above contents of this application do not necessarily constitute prior art. Utility Model Content
