In the course of various agricultural operations, machine tools must strictly adhere to the safety requirements outlined in the machine tool specifications. Operators should receive proper training in operating techniques, and it is recommended to seek technical guidance from local agricultural machinery departments for field operations. Below is a brief overview of key considerations when using several typical agricultural tools.
First, no-tillage sowing equipment plays a critical role in conservation tillage for crops like wheat and corn. During operation, operators must ensure good passability, avoid issues such as shaft wrapping, soil clogging, or blockages. The seed and fertilizer application parts should function smoothly without any sticking. For corn no-tillage seeders, specific performance indicators must be met:
- Seed spacing qualification rate ≥ 60%
- Replanting index ≤ 30%
- Missing broadcast index ≤ 15%
- Seed damage rate ≤ 1.5%
- Seeding depth compliance rate ≥ 75%
For wheat no-tillage planters, the row consistency coefficient of variation should be ≤ 3.9%, the total displacement stability coefficient of variation ≤ 1.3%, seed damage rate ≤ 0.5%, and seeding depth compliance rate ≥ 75%. Once these standards are met after proper debugging, the equipment can be put into production.
Second, deep loosening machines aim to break up compacted soil layers, improve water infiltration, and enhance soil structure. During use, it's essential to check whether the soil is properly loosened, if the plowed layer remains undisturbed, and if the working depth meets technical requirements. After commissioning and ensuring normal operation, the machine can be used in production.
Third, spraying equipment requires careful handling. Before starting, a representative section should be tested to evaluate herbicide effectiveness, insect control, and potential crop phytotoxicity. The liquid pump should be started before spraying, and the liquid switch turned on afterward. When stopping, the liquid supply should be shut off first. Wind direction and speed must be considered—spraying should not occur on windy days. The vehicle should move perpendicular or at an angle to the wind, maintaining a steady speed without sudden stops. Operators should continuously monitor spray quality, and after the job, they should assess weed control, pest management, and any crop damage. Protective gear, such as masks or respirators, must be worn, and eating or smoking is strictly prohibited during operation. Areas treated with highly toxic agents should be clearly marked to prevent accidental entry. Finally, all equipment should be cleaned and oiled promptly after use to maintain functionality.
These guidelines ensure safe and efficient operation while maximizing the benefits of modern agricultural machinery.
