Combined precision seeder

Abstract

The invention relates to a combined precision seeder, and belongs to the field of agricultural machinery and intelligent equipment. The combined precision seeder comprises a suspension machine frame, an anti-curving chopping knife, a rotary tillage knife, a subsoiler, a fertilizing mechanism and a compacting machine are sequentially arranged below the suspension machine frame from front to back, and a seed discharging mechanism, a compacting wheel and a leveler are sequentially arranged behind the compacting machine; and a tool magazine mounting rack is arranged on the suspension machine frame, an anti-curving chopping knife magazine provided with the anti-curving chopping knife and a rotary tillage knife magazine provided with the rotary tillage knife are respectively arranged at the lower end of the tool magazine mounting rack through respective shafts, and a three-edge cutter is arranged on the shaft of the anti-curving chopping knife magazine or the rotary tillage knife magazine or outside the shaft of the anti-curving chopping knife magazine or the rotary tillage knife magazine. By means of the agricultural machine and agricultural technology integrated innovative design, the working procedures of stubble cleaning and soil cutting, rotary tillage and soil preparation, deep scarification and bottom breaking, precise fertilization, land leveling and compacting, disc ditching, precise seed distribution, soil covering and pressing, leveling and soil moisture conservation and the like can be sequentially completed through one-time operation, and therefore the effects of precise tillage, precise fertilization and precise seeding are achieved.

Description

technical field [0001] The invention relates to an intelligent joint precision seeder, which belongs to the field of agricultural machinery and intelligent equipment, and is suitable for high-quality, precise and intelligent sowing of seeds of corn, soybeans, peanuts and other crops in hard stubble fields. Background technique [0002] The simplification and intelligence of crop production management is the trend of future agricultural development. Sowing is an important part of crop production. The quality of sowing significantly affects the uniformity of plant spatial distribution, crop population and individual development quality, and is an important basis for crops to achieve high-yield and high-quality production goals. In order to reduce the number of times the machine enters the field, reduce investment and improve efficiency, the demand for multi-functional combined seeders in crop production continues to increase. At present, the technologies protected by inventio...

AI Technical Summary

Problems solved by technology

However, with the increase of the functions of the sowing machinery, its structure becomes more and more complex, and it is often difficult to guarantee the stability and quality of sowing in the field.

The main problems are as follows: first, the quality of soil preparation is poor and the quality of sowing is not high; second, the machinery lacks wide adaptability, and grass entanglement and congestion often occur in plots with poor quality of straw returning to the field and sticky soil, which affects the quality of sowing and work efficiency; third, the method of fertilization is relatively simple and cannot meet the requirements of new technologies for precise fertilization; fourth, the degree of intelligence is low
