Sweet potato seedling throwing, soil covering and pressing device and sweet potato planter

Abstract

The invention discloses a sweet potato seedling throwing, soil covering and pressing device and a sweet potato planter; the sweet potato seedling throwing, soil covering and pressing device comprisesa rack, wherein a ditching and seedling throwing assembly, a soil covering assembly and a pressing assembly are sequentially arranged on the rack from front to back; a sweet potato seedling throwing mechanism and a furrow opener are arranged above and below the ditching and throwing assembly; a seedling falling groove is formed in the middle of the furrow opener, and the throwing end of the potatoseedling throwing mechanism directly faces the seedling falling groove; and the heights of the soil covering assembly and the pressing assembly relative to the rack are adjustable. The furrow opener,the sweet potato seedling throwing mechanism, the soil covering assembly and the pressing assembly are arranged, so that ditching, potato seedling throwing into ditches in a set posture, soil covering and soil pressing can be continuously executed, step-by-step operation is not needed, and the mechanization degree is high; the heights of the soil covering assembly and the pressing assembly relative to the rack can be adjusted, so that the soil covering depth and the soil pressing degree can be adjusted according to needs, and the device is suitable for transplanting and planting different types of sweet potatoes in different soils.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a sweet potato seedling throwing device and a sweet potato planter. Background technique [0002] Sweet potato is an important economic crop, food crop, feed, industrial raw material and new energy application raw material. Sweet potato originated in South America, China is currently the largest sweet potato planting country, the current total production of sweet potato in my country is second only to rice, wheat, corn food crops. [0003] The sweet potato planting industry is a labor-intensive industry with a low degree of mechanization. Generally, each link needs to be operated by a separate machine or completely relies on manual work, resulting in low planting efficiency. With the continuous transfer of rural labor forces, the amount of labor required , high labor intensity, high labor cost, and low comprehensive income have seriously affected farmers' enthusia...

AI Technical Summary

Problems solved by technology

[0003] The sweet potato planting industry is a labor-intensive industry with a low degree of mechanization. Generally, each link needs to be operated by a separate machine or completely relies on manual work, resulting in low planting efficiency. With the continuous transfer of rural labor forces, the amount of labor required , high labor intensity, high labor cost, and low comprehensive income have seriously affected farmers' enthusiasm for planting and restricted the healthy and rapid development of the industry

[0004] At present, the research and development of sweet potato planting machinery in China is still in its infancy, and there are relatively few sweet potato planting equipment, especially the transplanting of potato seedlings to the soil and the subsequent steps of covering and suppressing. It has high requirements and is difficult to realize with general planting machinery, thus restricting the mechanization process of sweet potato planting
