Description

Technical Field

[0001] The present invention relates to the technical field of seed vigor detection, and particularly to a multi-station automatic seed vigor modeling and high-efficiency sorting system with a disc structure. Background Art

[0002] In the process of agricultural production and seed industry development, seed vigor, as a key indicator to measure seed quality, is directly related to the germination rate, growth trend, and ultimately the yield and quality of crops. Therefore, accurately and efficiently detecting seed vigor is of crucial significance for the stability and development of agricultural production.

[0003] In the field of seed detection, most traditional seed vigor detection equipment adopts the method of detecting and sorting seeds one by one. This detection method has obvious limitations. In terms of efficiency, the process of detecting seeds one by one is extremely cumbersome. Each seed needs to be separately loaded, detected, and sorted. The detection speed is slow, resulting in low overall detection efficiency. When facing the demand for large-scale seed detection, the traditional method requires a large amount of time and labor costs and is difficult to meet the requirements of the rapid development of the modern seed industry.

[0004] Based on the above technical problems, those skilled in the art urgently need to develop a multi-station automatic seed vigor modeling and high-efficiency sorting system with a disc structure that can improve the efficiency of seed detection and reduce labor and time costs. Summary of the Invention

[0005] The purpose of the present invention is to provide a multi-station automatic seed vigor modeling and high-efficiency sorting system with a disc structure that can improve the efficiency of seed detection and reduce labor and time costs.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] The multi-station automatic seed vigor modeling and high-efficiency sorting system with a disc structure of the present invention, the sorting system includes:

[0008] A rotating base plate, on which there are three stations, namely a loading station, a detection station, and a sorting station; among them,

[0009] A loading mechanism is provided at the loading station, and through the loading mechanism, seeds are arranged in an array of single grains on the array aperture plate;

[0010] A multi-channel spectral detection unit is provided at the detection station for spectral detection of the seeds on the surface of the array aperture plate rotated to the detection station;

[0011] Three electromagnetic vibration devices can all rotate with the rotating base plate to each working station. There are three array aperture disks, which are respectively installed on the three electromagnetic vibration devices;

[0012] This sorting system further includes:

[0013] A transfer mechanism and a classification collection box arranged at the sorting station. The seeds in the array aperture disk are transferred to the classification collection box through the transfer mechanism.

[0014] Furthermore, the included angle between each working station on the rotating base plate is 120°, and the rotating base plate is driven by a servo motor.

[0015] Furthermore, the feeding mechanism includes a vacuum suction device installed at the feeding station, which can convey seeds from the storage position to the feeding station through negative pressure and stack the seeds on the surface of the array aperture disk;

[0016] A flexible brush assembly installed at the feeding station, which is used to push and sweep the redundant seeds on the surface of the array aperture disk.

[0017] Furthermore, the transfer mechanism includes a multi-channel nozzle array installed at the sorting station for sucking seeds; and

[0018] A multi-axis displacement stage installed at the sorting station for moving the multi-channel nozzle array, which can transfer seeds from the array aperture disk to the seed classification collection box.

[0019] Furthermore, the surface of the array aperture disk has array-type grooves with the same size as the seeds. When the electromagnetic vibration device is turned on, the seeds on the surface of the array aperture disk fall into the grooves through vibration to achieve array-type single-grain distribution. By controlling the frequency and amplitude of the electromagnetic vibration device, the speed of the seeds falling into the grooves can be increased.

[0020] Preferably, the multi-channel spectral detection unit has the same number of channels as the grooves on the surface of the array aperture disk, and can simultaneously perform spectral detection on a batch of seeds.

[0021] Preferably, the multi-channel nozzle array has the same number of channels as the grooves on the surface of the array aperture disk, and each channel can be individually opened or closed for sucking and releasing seeds.

[0022] Preferably, the seed classification collection box has two areas for containing high-viability seeds and low-viability seeds respectively.

[0023] In the above technical solution, the multi-station automatic seed vigor modeling and high-efficiency sorting system with a disk structure provided by the present invention has the following beneficial effects:

[0024] The multi-station automatic seed vigor modeling and high-efficiency sorting system with a disc structure of the present invention, firstly, solves the problem of low efficiency of traditional seed vigor detection equipment. Through the multi-station design on the rotating base plate, synchronous feeding, detection and suction of a large number of seeds are realized, greatly improving the seed detection rate and better meeting the needs of the continuous expansion of seed production scale in the process of agricultural modernization. Secondly, the combined use of the vacuum suction device, the electromagnetic vibration device and the array aperture disc enables the seeds to be distributed in a single-grain array, laying a foundation for subsequent accurate detection and sorting.

[0025] Furthermore, the multi-channel spectral detection unit has the same number of channels as the surface grooves of the array aperture disc, and can simultaneously perform spectral detection of a batch of seeds, further improving the detection efficiency. In addition, each channel of the multi-channel nozzle array can be individually opened or closed. Combined with the movement of the multi-axis displacement stage, it can accurately transfer seeds with different vigor, ensuring the accuracy of seed classification. Finally, the reasonable design of the seed classification collection box ensures that all seeds can accurately fall into the corresponding areas, realizing the effective separation of high-vigor seeds and low-vigor seeds, providing more reliable technical support for agricultural production and seed industry development, and reducing labor and time costs.
