AI Technical Summary

Technical Problem

Traditional trenchers have poor adaptability to different soil environments, insufficient stability in trench formation, and limited precision in variable fertilization, making it difficult to meet the needs of modern precision agriculture.

Method used

It adopts a soil-breaking mechanism with retractable breaking claws, a reinforcement mechanism driven by planetary gear system, and a fertilization mechanism with rotating column to adjust the amount of fertilizer, so as to achieve flexible switching of soil-breaking mode, compaction of ditch sidewalls, and precise control of fertilizer amount.

Benefits of technology

It reduces the resistance of the trench opener in hard soil layers, ensures stable trench formation, improves the uniformity and precision of fertilization, and meets the requirements of modern precision agriculture.

Abstract

The invention discloses a furrow opener with a variable fertilization function, and belongs to the technical field of intelligent agricultural machinery, the furrow opener comprises a main frame, a driver is arranged above a main frame body, two crawler belts are arranged between the main frame body, two support frames are arranged at the top of the main frame body, and a ground breaking mechanism comprises a breaking claw arranged on one side of each crawler belt; the reinforcing mechanism comprises a plurality of contact plates arranged below the main frame, the fertilizer applying mechanism comprises a rotating column arranged above the supporting frame, a material containing groove is formed in the outer wall of the rotating column, and the fertilizer applying mechanism is arranged in the material containing groove. Hard soil pre-crushing and resistance reduction are achieved through a telescopic breakthrough claw of the soil breaking mechanism, a self-adaptive floating reinforcing mechanism driven by a planetary gear train is combined to ensure ditch wall forming and collapse prevention, and a releasing mechanism is used for adjusting the physical volume of a material containing groove to achieve precise variable rate fertilization at a constant speed. The adaptability of the furrow opener to complex soil texture, the operation stability and the uniformity of fertilization distribution are improved.
