Description

Technical Field

[0001] The utility model relates to the technical field of rice seedling throwing machines, in particular to a wind-blown high-speed rice seedling throwing machine. Background Art

[0002] In recent years, rice farmers have expanded their cultivated areas. Although manual tossing is the primary method for planting rice seedlings, which is more time-efficient and faster than transplanting, the shortage of rural labor and rising labor costs have led to a series of challenges. Rice seedling throwers are a promising option. Mechanized rice seedling raising and planting can easily achieve high and stable yields, saving time and labor compared to manual tossing. Mechanical tossing is a new, recently developed, mechanized rice planting technology. Typically used for mid-season or late-season rice, this method allows for warm weather and soil that allows the roots to easily settle and grow. Tossing seedlings into the air, where they free-fall into the soil, creating an irregular, disordered arrangement. The centrifugal force generated by the high-speed rotation of the tossing disc evenly distributes the seedlings, laden with soil, into the field, completing the planting process. However, because tossing is currently performed manually, the process is highly random, making it difficult to effectively control the uniformity and density of the tossing, which directly impacts the yield-increasing benefits of tossing. Consequently, the main drawback of tossing machines is uneven planting. Utility Model Content
