Embodiment Construction

[0028] The present invention will be further described below in conjunction with accompanying drawing:

[0029] Such as Figure 1-Figure 2 The shown online detection device for internal cracks of rice seeds includes a feeding module, a transmission module, a detection module, a sorting module and a control module 15 .

[0030] The feeding module includes a vibration feeder 2 and an inclined chute 3 connected to the outlet of the vibration feeder 2 . The chute 3 is V-shaped. The length of the chute 3 is 20mm, the width is 10mm, and the depth is 5mm. A feed hopper 1 is installed on the vibrating feeder 2 . The feed hopper 1 is a hollow structure with a cylindrical upper end and a frustoconical lower end, so that the seeds entering the feed hopper can fall freely.

[0031] The transmission module includes a conveyor belt 4 and a transmission mechanism for driving the conveyor belt to rotate. The transmission mechanism adopts the existing structure. Such as figure 2 As sho...

Abstract

The invention relates to an online detection device and a detection method for internal cracks in rice seeds. The detection device includes a feed module, a transmission module, a detection module, a sorting module and a control module. The feeding module includes vibratory feeders and chutes. The transport module includes a conveyor belt. A number of uniformly distributed counterbores are provided on the conveyor belt; a through hole is provided at the bottom of the counterbore. The detection module includes a halogen light source, an optical shutter and a fiber optic probe, a position sensor, and a hyperspectral imager set above the conveyor belt. Fiber optic probes and position sensors are installed between the upper and lower layers of the conveyor belt. The sorting module includes several storage bins and several first high-pressure gas nozzles. The control module includes a controller and a microprocessor. The microprocessor is connected with the hyperspectral imager. The controller is interactively connected with the position sensor and the optical shutter respectively. The invention can solve the deficiencies in the prior art, and realize fast and non-destructive on-line detection of internal cracks in large batches of rice seeds.

Description

technical field [0001] The invention relates to the technical field of seed quality detection, in particular to an on-line detection device for internal cracks in rice seeds and a detection method thereof. Background technique [0002] my country is the world's largest rice producer, and its total output ranks first in the world. According to statistics from the Food and Agriculture Organization of the United Nations, from 1961 to 2013, the average annual rice planting area in my country was 31.857 million ha 2 , accounting for 34.97% of the average planting area of ​​grain crops in my country and 22.12% of the world's rice production area. The average total rice output in my country is 156 million tons, accounting for 48.39% of my country's total grain output and 33.7% of the world's total rice output. Due to the large population and rapid economic development in my country, the limited arable land area is decreasing year by year. Objectively, it is required to greatly in...
