Real-time monitoring system for stone in rice seedlings with automatic cleaning device and control method

Abstract

The invention provides a real-time monitoring system for stone in rice seedlings with an automatic cleaning device and a control method. A reflective photoelectric sensor is utilized for monitoring the rotation speed of planting arms to achieve real-time monitoring and alarming on the stone in the rice seedlings; in order to prevent the situation that when a rice transplanter works, muddy water in a rice field is splashed on the sensor and the normal work of the sensor is influenced, a dustproof cover and an automatic dust removal device are installed for the sensor. The reflective photoelectric sensor installed on a power transmission box is utilized for collecting the rotation speed of the planting arms, an MCU analyzes the speed change sensed by the sensor, in cooperation with the automatic dust removal device, real-time monitoring and alarming on the stone in the rice seedlings are achieved, and the MCU sends fault information to a remote monitoring terminal. The real-time monitoring system for the stone in the rice seedlings with the automatic cleaning device and the control method have the advantages that the intelligence degree is high, transformation is simple, the cost is low, the system can be installed and used simply by small modification of the existing rice transplanter, and the application range is wide.

Description

technical field [0001] The invention relates to a real-time monitoring system and control method for rice seedling stones with an automatic cleaning device, belonging to the field of intelligent agricultural machinery. Background technique [0002] Now the rice shoots used by the rice transplanter in my country are seedlings with soil, and the seedling raising method is seedling raising tray seedling raising. Since there are no normative requirements for the seedling raising process at present, hard objects such as stones in the soil are brought to the seedling raising tray. When transplanting rice seedlings, when the planting mechanism encounters stones, the clutch of the splitting mechanism is disengaged and the problem of rice transplanting cannot occur frequently. If it cannot be found in time, it will cause missed insertion of rice seedlings and damage to the planting mechanism. At present, the on-board personnel of the rice transplanter mainly judge whether there are ...

Problems solved by technology

However, the installation of a rotation angle sensor on the drive shaft of the split-insertion mechanism requires modification of the drive shaft of the existing split-insert mechanism. The effective detection distance of the sensor is limited (<1cm), and the proximity sensor needs to be kept within the effective detection distance with the insertion mechanism. During actual operation, mud will splash between the sensor and the insertion mechanism, resulting in reduced monitoring performance or damage to the sensor. Therefore, it must be developed New technology and device for real-time monitoring of stones in seedlings and alarm for shutdown

[0003] In the prior art, the applicant has not yet discovered the technology and device for real-time monitoring of stones in rice seedlings by using an automatic dust removal device to eliminate the interference of the reflective photoelectric sensor to the monitoring of the speed of the transplanting mechanism of the rice transplanter
