Vertical rotary cultivator capable of chopping green manure and returning green manure to field and application

Abstract

The invention discloses a vertical rotary cultivator capable of chopping green manure and returning the green manure to the field and application. The vertical rotary cultivator comprises a mounting plate, a hanging ring is fixedly connected to one end of the mounting plate, a roller set is fixedly connected to the end, away from the hanging ring, of the mounting plate, a chopping cylinder penetrating through the mounting plate is fixedly connected to the mounting plate, a plurality of blade bars are rotatably inserted in the chopping cylinder, rotary blades are fixedly connected to the side faces of the ends, below the mounting plate, of the blade bars, a first chopping system is fixedly connected to the inner bottom of the chopping cylinder, a second chopping system fixedly sleeves the blade bars, the first chopping system corresponds to the second chopping system, and a feeding pipe is fixedly connected to the outer top of the chopping cylinder and communicated with the chopping cylinder. A method for returning green manure to the field and performing rotary tillage at the same time is introduced, and chopping of green manure such as Chinese milk vetch and oilseed rape is realized. The blade angle and blade corner of the chopping systems can be adjusted, the structure is compact, and the returning-to-field effect is good.

Description

technical field [0001] 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. Background technique [0002] 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 lar...

[0002] 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
