Abstract
Description
Technical Field
[0001] The utility model belongs to the field of agricultural machinery, and in particular relates to a novel CCD seed quantity monitoring system for an electronically controlled seeder. Background Art
[0002] A seeder is a type of agricultural machinery that accurately controls seed sowing depth, plant spacing, row spacing, and seeding rate according to agronomic requirements. With the rapid development of agricultural technology in my country, electronically controlled precision seeders are gaining acceptance among farmers due to their high speed, consistent seeding depth, precise plant spacing, high seeding efficiency, and high operational quality. However, due to the wide variety of soil conditions, high dust levels, and harsh environments in which seeders operate, traditional infrared sensors are susceptible to dust accumulation, resulting in inaccurate readings. Furthermore, infrared sensors are insensitive to light fluctuations and have high environmental requirements. Utility Model Content
[0003] The utility model provides a novel CCD seed quantity monitoring system for an electric control seeder. The CCD sensor is used on a seed transfer tube to perform counting, and has little influence from the external environment and dust, thereby achieving accurate counting.
[0004] The technical solution adopted by this utility model is:
[0005] A new CCD seed quantity monitoring system for electronically controlled seeders uses a CCD monitoring structure installed on the seeder's seed transfer tube. Using a through-beam CCD monitor to count seeding quantities, it minimizes environmental influences and enables more stable seed quantity counting.
[0006] As a preferred embodiment of the present invention, the CCD monitoring structure includes a photoelectric emitting assembly and a photoelectric receiving and processing assembly. The photoelectric emitting assembly includes a transmitting housing and a photoelectric emitting board, the photoelectric emitting board being mounted within the housing with the signal transmitting end of the photoelectric emitting board facing the photoelectric receiving and processing assembly. The photoelectric receiving and processing assembly includes a photoelectric receiving housing, a photoelectric receiving board, and a processing board, the photoelectric receiving board and processing board being mounted within the housing. The processing board is provided with an MCU processing module, a communication module, and a power supply module. The signal receiving end of the photoelectric receiving board corresponds to the signal transmitting end of the photoelectric emitting board. The output end of the photoelectric receiving board is connected to the MCU processing module, which is in turn connected to the communication module. The power supply module supplies power to the photoelectric receiving board, the MCU processing module, and the communication module. The transmitting housing and the photoelectric receiving housing are mounted on opposite sides of the seed sowing and seed transfer tube in a facing configuration.
[0007] As a preferred solution of the present invention, the power supply module is 12V direct current.
[0008] As a preferred solution of the present invention, the power supply module includes a tractor battery and a step-down and voltage-stabilizing module. The tractor battery is stepped down and stabilized into 12V DC by the step-down and voltage-stabilizing module and then supplies power to the photoelectric receiving board, MCU processing module and communication module.
[0009] As a preferred solution of the present invention, the communication module is a 485 communication module. RS485 communication has strong anti-interference and fast transmission speed and can communicate with the host computer.
[0010] The utility model uses CCD sensor as a monitoring component to detect the number of seeds passing through the sowing and seed transfer tube. The detection of seeds is achieved through the photoelectric transmitting plate and the photoelectric receiving plate installed on both sides of the sowing and seed transfer tube. The photoelectric sensor signal is less affected by the external environment and has high detection accuracy. BRIEF DESCRIPTION OF THE DRAWINGS
