Description
技术领域technical field
本发明涉及农用机械领域，尤其涉及一种将多种绿肥切碎还田的垂直旋耕机具及应用。The invention relates to the field of agricultural machinery, in particular to a vertical rotary tiller for chopping and returning various green manures to the field and its application.
背景技术Background technique
随着我国科学技术的进步，现代农业慢慢渗透进我国的农业发展，农业生产的机械化程度越来越高，其中旋耕机具及应用作为一种很常见的农机设备，其在我国的普遍性很强，当然为了满足不同的种植需求，各式各样的旋耕机具及应用也慢慢浮现出来，要能切碎多种绿肥，紫云英和油菜属于一种重要的绿肥作物，紫云英固氮能力强，若能被切碎腐解可大量激发土壤氮素，茎系发达，错综杂乱，切割容易缠绕机械，且切割不到位不利于腐肥，油菜属于直系根，茎直立分支较少,株高30到90cm，根系发达，整个根系直接施到土地时不利于土壤吸收，并而当前的旋耕机具及应用在功能上大多不能实现多功能的叠加，当使用者需要将绿肥还田时，就需要将绿肥进行实现的粉碎，然后再进行人工还田，这样会导致绿肥与土壤的混合性不强，同时效率低下，劳动强度高。With the advancement of science and technology in our country, modern agriculture has slowly penetrated into the agricultural development of our country, and the degree of mechanization of agricultural production has become higher and higher. Among them, rotary tillage tools and their applications are very common agricultural machinery and equipment, and their universality in our country Very strong. Of course, in order to meet different planting needs, a variety of rotary tillage machines and applications have gradually emerged. To be able to chop a variety of green manure, milk vetch and rapeseed are an important green manure crop, milk vetch Nitrogen fixation ability is strong. If it can be chopped and decomposed, it can stimulate a large amount of soil nitrogen. The stem system is well developed and messy. It is easy to entangle the machine when cutting, and not in place is not conducive to composting. Rapeseed belongs to the straight root, and the stem has few erect branches. The plant height is 30 to 90 cm, and the root system is well developed. When the whole root system is directly applied to the land, it is not conducive to soil absorption, and most of the current rotary tillage machines and applications cannot achieve multi-functional superposition. When the user needs to return the green manure to the field , it is necessary to crush the green manure, and then return it to the field manually, which will lead to poor mixing of green manure and soil, low efficiency and high labor intensity.
