Problems solved by technology

[0002] The rice direct seeding machine can reduce the workload and seed quantity of rice sowing, but since the sowing amount is generally 2 to 6 seeds per hole, if there is a missed sowing, it will seriously affect the emergence rate, and then affect the rice yield. It is of great significance to monitor the state

Abstract

The invention discloses a monitor system for seeding state of a seeding mechanism of a paddy planter. The system comprises an infrared transmitting tube D1 and an infrared receiving tube which are arranged separately at two opposite sides of the seeding tube, a comparator connected with the infrared receiving tube and a control system connected with the comparator. The infrared receiving tube transmits a signal result received from the infrared transmitting tube to the comparator according to the situation of seeds falling, and the comparator compares the preset reference voltage to the signal voltage and outputs a pulse signal of seed state. The control system calculates the seeding quantity and the amount of seeding holes according to the pulse signal, and determines the seeding situation of a seeding port of the paddy planter. The system has the advantage of accurate monitoring result, can monitor the seeding quantity in real time and effectively reduce missing of seeding.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, and relates to a monitoring system for detecting the whereabouts of seeds at a seeding port of a rice direct seeding machine by using infrared emission and reception technology. Background technique [0002] The rice direct seeding machine can reduce the workload and seed quantity of rice sowing, but since the sowing amount is generally 2 to 6 seeds per hole, if there is a missed sowing, it will seriously affect the emergence rate, and then affect the rice yield. It is of great significance to monitor these conditions. Contents of the invention [0003] Aiming at the shortcomings of the prior art, the purpose of the present invention is to provide a monitoring system for monitoring the accurate seeding status of the rice direct seeding machine seed metering device. [0004] In order to achieve the above object, the technical solution of the present invention is: a monitoring sys...
