The Yuanhang Junong 2BQ-8 intelligent precision seeder is based on the high speed sowing operation conditions of various large grain crops such as corn and soybeans (single), which have large coefficient of variation in grain spacing, poor uniformity of fertilizer application, poor consistency of seed and fertilizer application depth, large pressure fluctuations and blockage of soil contact components. Jilin Agricultural Machinery Research Institute, in collaboration with Jilin Yuanhang Agricultural Machinery Co., Ltd., adopts the principle of positive pressure pneumatic conveying and integrates central centralized sowing and fertilization technology No-tillage seeding technology, mechatronics and hydraulic integration technology, intelligent technology, research on fertilizer pneumatic conveying technology, active profiling and pressure control technology of seeding units, development of key components such as seed metering device, centralized fertilization device, electric proportional hydraulic valve group, and no-tillage seeding unit and the creation of an 8-row pneumatic high-speed intelligent precision seeder, which can complete seed bed treatment, trenching, fertilization, precision seeding and soil covering in one go. For operations such as suppression, the sowing quality is higher than the national standard and the operating speed is above 10km/h.

Product performance characteristics:
   1. By collecting real-time driving speed through radar, converting it into analog signals, controlling the speed of the fertilization motor and the seeding motor to achieve the goal of precise fertilization and seeding;
   2. By using a miss-seeding sensor and a standard controller, the control accuracy is improved through programming control and the counting error of the miss-seeding sensor is ≤ 3%;
   3. Intelligent control system, which can achieve:
      » Monitoring and participating in action control of the rotation angle of the seeder seeding unit;
      »Alarm monitoring of seed yield, fertilizer yield, sowing channel, etc;
      »Set sowing spacing and fertilizer application amount according to needs;
      »Real time monitoring of fertilizer application speed, fan speed and sowing quantity in each channel;
      »Protection level IP65, working temperature -20-70 ° C.
