Spin milling type multifunctional machine for deeply ploughing and crushing ridges

Abstract

The invention discloses a spin milling type multifunctional machine for deeply ploughing and crushing ridges, which is based on a tractor. A hydraulic mechanism and a linking spin milling drill bit device or a cultivation component is arranged on a rear frame of the tractor; the linking spin milling drill bit device is provided with one or more drill bit shafts; spiral hinges are arranged on the drill bit shafts and provided with apical teeth; the linking spin milling drill bit device is provided with a device for preventing a straw from being wound; the hydraulic mechanism drives a spin milling drill bit to move up and down; and a gearbox drives the spin milling drill bit by a connecting rod and a gear. According to the spin milling type multifunctional machine, the drill bit enters into soil and then vertically cuts, spin mills and crushes the soil and ensures that the soil is automatically suspended to form the ridges; the soil crushing section of the crushed ridge is T-shaped; the lower part of the compacted soil on the ground is in a U-shaped groove, so that the whole layer of the soil is in a loosing state during cultivation; and in addition, the invention plays roles of covering and replacing the soil, increases an active layer, improves the capabilities of preserving moisture and fertility and the permeability of the soil, benefits the utilization of deep growing of the crop root system to water and fertilizer, relatively reduces pests and weeds and ensures that the crop is easy to obtain high and stable yield.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a land tillage machine which deeply plows and breaks soil into ridges by means of rotary milling. Background technique [0002] In the thousands of years of civilization history of our country, agriculture plays an important role in the whole production. With the development of social economy, in order to increase production and improve labor productivity, working people invented and created a variety of agricultural production tools, not only in large numbers, but also relatively early in time. For example, iron appeared in the Warring States period. After the Han Dynasty, large-scale iron plowshares were manufactured, and advanced production tools and farming methods were vigorously promoted. In the entire ancient society, the development level of my country's plow has always been at the forefront of the development of agricultural technology in the world. Although modern China's scien...

Problems solved by technology

[0010] The purpose of the present invention is to provide a land farming machine that uses rotary milling to deep plow and break the soil into ridges, so that it is suitable for deep plowing of crops and can overcome the degradation of land quality caused by the existing shallow plowing process, serious soil compaction, and transparent The problem of sexual decline

[0011] The applicant realized that there is a better method to overcome the existing problems of severe soil compaction and decreased permeability, so on March 17, 2010, he applied for the invention patent of "Fenlong Cultivation Method for Dryland Crops" to the State Intellectual Property Office , application number: 201010125942.4 publication (announcement) number: CN101779537A applicant (patent) person: Institute of Economic Crops, Academy of Agricultural Sciences, Guangxi Zhuang Autonomous Region Inventor (designer): Wei Benhui; Gan Xiuqin; Yu Jian; He Zhangjie; Lu Liuying, etc., the invention is disclosed A cultivation method for crops in dry land, using rotary tillage spiral machinery to deeply loosen furrows and silt, crush the loosened soil of the plow layer and the plow bottom layer, and part of the guest soil on the plow bottom layer floats up and mixes with the soil of the plow layer to form ridges naturally. The furrow is trapezoidal, with a furrow width of 25-30 cm and a furrow depth of 80-100 cm. The distribution of silt soil is in a "T" shape. The ridge width of the powder ridge can reach 70-80 cm, and the height of the ridge is 20-25 cm; or the furrow width is 50 cm. cm, and the ditch depth is 60-70 cm, the width of the ridge is about 90 cm, and the height is about 20 cm. After the silt soil of the machine ditch is formed into a ridge, it can be sown or planted
