Real-time adjustable and controllable type double-layer bionic notch circular-disc furrow opener

Abstract

The invention provides a real-time adjustable and controllable type double-layer bionic notch circular-disc furrow opener and belongs to the technical field of agricultural machinery. According to thereal-time adjustable and controllable type double-layer bionic notch circular-disc furrow opener, a notch circular-disc assembly I and a notch circular-disc assembly II are symmetrically arranged relative to an a-a central longitudinal axis; a furrow opening handle is fixedly connected to a top center of a base in a connection part; the right end of a connection shaft in the notch circular-disc assembly I is fixedly connected with a shaft sleeve I of a connection part through a screw I; the left end of the connection shaft in the notch circular-disc assembly II is fixedly connected with a shaft sleeve II of the connection part through a screw II; a circular-disc disc body soil-entering furrow opening section is provided with a corrugated bionic curve surface; a circular-disc notch soil cutting blade is obtained by symmetrically cutting a disc body curve surface through a bionic curve; a circular disc stubble-breaking and soil-entering tool has two forms including a circular arc edge and a bionic tooth-shaped edge; a cutting edge of the circular arc edge has a bionic included angle; the bionic tooth-shaped edge is a tooth-shaped micro-structure with a bionic coupling design. The real-time adjustable and controllable type double-layer bionic notch circular-disc furrow opener has the advantages of strong wear resistance, excellent soil-entering performance, good soil crushing andstubble breaking performance, high working efficiency and long service life, is applicable to different working environments can be used for initiatively replacing the edge.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a real-time adjustable double-layer bionic gap disc fertilization ditch opener. Background technique [0002] Conservation tillage is a new type of tillage technology, which mainly includes four basic contents of stubble mulching, no-tillage fertilization and seeding, pest and weed control, and subsoiling. Conservation tillage can reduce plowing and harrowing and return crop residues such as straw and root stubble to the field, which is conducive to protecting soil structure, increasing soil organic matter content, and reducing soil loss. It is an important way to achieve sustainable agricultural development. [0003] With the development and promotion of conservation tillage techniques and models, the intertillage operations in the crop planting process are gradually being simplified. In the process of no-tillage operation, there are a lot of straw re...
