REAL-TIME MISSED SEEDING MONITORING PLANTER BASED ON RING-TYPE CAPACITANCE DETECTION SENSOR

Abstract

In order to improve the quality of corn sowing and fertilizer utilization, reduce labor costs, this paper aimed at the traditional tillage fertilizer machine to improve. The seeding and fertilizing machine with adjustable flow is designed by integrating particle fertilizer sensor and CAN bus transmission technology. It is mainly composed of seed and fertilizer discharging mechanism, ditch and soil covering mechanism, and leakage seeding and blockage monitoring system. Fertilizer drop signal can be obtained in real time by detecting the flow sensor outside the fertilizer discharge pipe. The speed of the stepper motor can be adjusted after signal processing, which can also realize the alarm of missing sowing and blocking light, and realize the precise variable sowing. The field experiment results show that the maximum relative error of seed leakage rate monitoring is 3.75%, and the alarm accuracy of fertilizer clogging is high. This machine can reduce the intensity of manual operation, and the quality of operation can be effectively monitored and controlled, can effectively reduce the production cost, has better practicability and economy.
