Description

Technical Field

[0001] The invention relates to the technical field of agricultural and forestry mechanical reclamation, and in particular to a rotary shovel type oil-tea tree forest reclamation machine. Background Art

[0002] Camellia oleifera fruit is a unique pure natural high-grade oil in my country, known as "Oriental olive oil", with high nutritional value. There are 45.312 million mu of camellia oleifera forests in my country, and the current output level is very low, with only about 5.8 kg of oil per mu. Jiangxi is the main production area of ​​camellia oleifera, with a planting history of more than 2,300 years, and its area and output rank second in the country. Camellia oleifera is a deep-rooted tree species, mostly planted in strips of low mountains and hills. Various shrubs are easily formed in its forests, and how to efficiently remove deep-rooted shrubs to prevent them from competing with the roots of camellia oleifera for water and fertilizer is the key to the cultivation and management of camellia oleifera forests. At the same time, reclamation of camellia oleifera plays an important role in maturing and improving soil, increasing fertility, removing weeds and eliminating pests and diseases. The existing camellia oleifera forests have not been reclaimed for a long time, and the roots of the shrubs in the rows are dense, which is easy to compete with the camellia oleifera trees for water and fertilizer; and the soil is compacted, which is not conducive to the deep rooting of the camellia oleifera trees. Since reclamation of camellia oleifera requires a lot of heavy physical labor, it is urgent to realize efficient and simple mechanized technology. Since the reclamation of oil-tea plantations can increase the yield of oil-tea plants, the development of oil-tea tending equipment (i.e., oil-tea reclamation machines) for horticultural oil-tea plantations is of great significance to increasing the yield of oil-tea plants and realizing mechanized operations of oil-tea plants. However, the current reclamation machines have shallow tillage depths and are too large in size, so the development of lightweight and efficient reclamation machines is a difficult problem in the development of machinery for tending oil-tea plantations.
