Intelligent corn stubble avoiding device of corn-stubble-avoiding no-tillage wheat planter

Abstract

The invention belongs to the field of agricultural machinery and particularly relates to an intelligent corn stubble avoiding device of a corn-stubble-avoiding no-tillage wheat planter. The device comprises a frame (10), a corn stubble row identification device, a transverse moving device, a rotating device and a control center and is characterized in that the frame (10) is a hollow three-dimensional frame and comprises a front upper beam, a front lower beam and a rear lower beam, and a three-point suspension mechanism (1) is arranged above the middle of the frame (10). The device has the advantages that stubble row information is acquired through the corn stubble row machine vision identification system, arrow-shaped shovels are controlled to avoid corn stubbles by transverse moving and rotating, the transverse moving device guarantees that a furrower can avoid the corn stubble rows, the device advances during transverse moving, the rotating device guarantees that the directions of the tips of the arrow-shaped shovels and the actual moving directions of the arrow-shaped shovels are kept consistent, the transverse moving resistance of the arrow-shaped shovels in soil is reduced, the operation quality of wheat no-tillage operation is guaranteed, and operation efficiency is increased at the same time.

Description

Technical field [0001] The invention belongs to the field of agricultural machinery, and particularly relates to an intelligent row counter device for a wheat counter-row no-tillage planter. Background technique [0002] No-tillage planting is a core technology of conservation tillage. It can be planted without turning over the topsoil and covering with crop straws, which can effectively reduce soil wind and water erosion, improve soil physical and chemical properties, and increase soil fertility, which is beneficial to North China for a year Save water and fertilizer in Liangshu District. After the corn stubble is harvested, the straw coverage is large and the toughness is strong, which makes it difficult for the planter to pass, which affects the seeding quality. How to sow with the crop straw covered is the key to no-till seeding. At present, some foreign countries that have carried out no-tillage planting earlier, such as the United States, Australia, etc., have relatively m...

Problems solved by technology

After corn stubble is harvested, the stalks cover a large amount and have strong toughness, which makes it difficult for the seeder to pass through and affects the quality of sowing. How to sow under the condition of crop stalks is the key to no-tillage sowing

At present, some foreign countries that carried out no-tillage sowing earlier, such as the United States and Australia, have relatively mature no-tillage sowing equipment, but these equipment are mostly large-scale traction, using multi-beam structures for anti-blocking, and relying on their own gravity Cutting stubble and digging ditches is not in line with the reality that the two-cropping area in North China has small plots, a large amount of straw coverage and insufficient purchasing power of farmers

In recent years, domestic researchers have put forward the idea of ​​row sowing, that is, avoiding corn stubble, and developed a series of wheat row no-tillage seeders based on the actual operation conditions of the farmland and the purchase characteristics of farmers. When sowing opposite rows of wheat in double-cropping areas in North China, the operator’s driving experience is mainly used, which directly reduces the operation efficiency and quality of row sowing
