Description

Technical Field

[0001] The utility model relates to the field of planting machines, in particular to a rice planting machine. Background Art

[0002] Selenium-rich rice is grown by supplementing selenium during rice planting, that is, supplementing selenium elements, so as to grow selenium-rich rice. It is a functional agricultural product, a selenium-rich food, and has high nutritional value. Large-scale rice planting mostly uses large-scale rice seeders, which can sow rice automatically at a uniform speed, greatly improving the sowing efficiency and reducing labor costs. However, in economically underdeveloped areas or small rice planting areas, farmers do not have the ability to purchase large-scale automatic rice seeders, and mostly use manual sowing, which results in uneven rice seeds and uneven seedlings, which can easily lead to uneven density. After the seedlings emerge, the seeding density needs to be re-sown to ensure uniform seedling density and appropriate depth, which is conducive to the normal emergence of rice and ensures a good harvest.

[0003] The existing planting machine barrel is provided with a plowboard. When the rice planting machine is moved, when passing through flat ground or concrete ground, the turning wheel is difficult to rotate, and it is laborious to push and easy to wear the turning wheel. The foldable roller can be lowered by rotating the bolt when necessary, replacing the rotating wheel as the front support wheel of the frame, which facilitates movement and saves time and effort.

[0004] The existing planting machine inserts the rice seedlings into the paddy field through the rolling process of the plow wheel, but the rolling height of the plow wheel is a fixed position, but the depth of the paddy field soil is different, which will cause the plow wheel to fail to completely and stably insert the rice seedlings into the paddy field soil, requiring manual re-checking and repeated insertion, affecting the stability of planting.
