Single-grain seeding detection alarm device

Abstract

The invention discloses a single-grain seeding detection alarm device, and belongs to the field of automatic detection alarm. The seeding detection alarm device is connected at a position between upper and lower planter seeding pipes, and the interior of a sleeve where the seeding detection alarm device is provided with an upper grating sensor and a lower grating sensor which are intersected witheach other. The inclination angles of the grating sensor relative to the horizontal plane can be adjusted. An initial signal is generated when seeds pass through an infrared detection alarm network, and the signal is transmitted to a single-chip microcomputer through a wireless transmitting device. The single-chip microcomputer carries out the processing of the signal to obtain the seeding quantity and quality of a planter in a time unit, thereby achieving the real-time detection alarm of the seeding quantities when the planter carries out the seeding of the seeds in different sizes, and avoiding the seeding leakage and repeated seeding.

Description

technical field [0001] The invention belongs to the field of agricultural engineering seeding machinery, and relates to a single-grain seeding detection and alarm device. Background technique [0002] In recent years, with the development of automation technology and precision sowing technology, the sowing efficiency and labor cost have been greatly improved. The quality of the seeding state during the operation of the seeder has a direct impact on the qualified rate of sowing. During the working process of the seeder, when it is affected by the lack of seeds in the seed box, the blockage of the seed tube, and the failure of the seed meter, it will cause missed seeding and reseeding, which has a great impact on crop yield. Therefore, it is particularly important to carry out real-time detection and alarm to the seeding state of the seeder in operation. [0003] At present, there are mainly traditional sampling method, image method and photoelectric method for the detection ...

AI Technical Summary

Problems solved by technology

The traditional sampling method can detect and alarm the seeding state more intuitively and accurately by sampling the falling seed flow in a distributed manner, but there are problems of inconvenient sampling and low efficiency; the image method uses a high-speed camera to monitor the falling seed flow. Real-time acquisition, intuitive and accurate information on the whereabouts of seeds after analysis, but there are problems that optical components are susceptible to environmental pollution and high cost; photoelectric methods use capacitive sensors, inductive sensors and other devices to extract pulse signals generated when seeds fall After analysis, the real-time seeding status of the seeder is obtained. This method has a simple structure and low cost, but because the electrical characteristics of different types of seeds are different, this method is only suitable for detecting and alarming specific types of seeds, and due to the detection and alarm blind area Existence causes the detection and alarm results to be inaccurate
