Description

TECHNICAL FIELD

[0001] The application belongs to the field of corn kernel quality detection, and particularly relates to a multi-stage shunting corn kernel crushing detection device and method. BACKGROUND

[0002] During the mechanical harvesting process, corn kernels are prone to be rubbed and collided by operation components, thereby causing mechanical damage of different degrees, which seriously affects the harvesting quality and benefits. Therefore, the kernel crushing rate has become an important indicator for measuring the operation performance of the corn kernel harvesting machine. During the harvesting process, the operation component working parameters can be dynamically regulated through real-time detection of the crushing, so as to realize efficient and low-loss harvesting of the corn kernels. At present, the kernel crushing rate detection mainly adopts a visual detection method based on image recognition. However, under the machine harvesting operation, the kernel flow is large and fast, and the samples are prone to be stacked and overlapped, thereby affecting the recognition accuracy and detection stability of the visual algorithm. Therefore, how to realize the quantitative, orderly and single-layer distribution of the kernel samples is of great significance for improving the visual detection accuracy and reliability of the kernel crushing.

[0003] The application patent CN118225764A is a harvesting machine grain tank kernel impurity rate and crushing rate monitoring device and method, which realizes the single-layer sparse distribution of the kernels by adopting a groove wheel conveying mechanism. However, this technology is limited by the volume of the groove wheel, is only suitable for intermittent feeding of a small amount, is difficult to meet the high-throughput detection demand under the machine harvesting condition, and is prone to cause the groove wheel to be blocked due to the concentration of the materials. The application patent CN112001283A is an online detection device and detection method for the crushing rate of corn kernels, which realizes the single-layer dispersion of the corn kernel samples by adopting a material falling chute and a single-layer plate. However, this technology can only passively adjust the feeding state of the corn kernels, cannot realize gap quantitative sampling, the crushing rate detection result fluctuates greatly, and the stability is insufficient under the complex machine harvesting environment. Therefore, it is of important application value to develop a compact, stable shunting and controllable sampling corn crushing detection device and method for improving the accuracy and stability of the corn kernel crushing detection under the machine harvesting environment.
