Description

Technical Field

[0001] This application relates to the field of chestnut worm eye detection technology, and in particular to a chestnut worm eye detection device. Background Technology

[0002] Chestnut is a deciduous tree belonging to the genus *Castanopsis* in the family Fagaceae. Its stems and branches are relatively thick and cylindrical, with a dark green surface covered with fine longitudinal striations and small hairs. The leaves are mostly curled, with short petioles, and are elliptical in shape with a yellowish-brown surface. Young leaves are covered with fine hairs. The flowers are small and pale yellow, with a large corolla and a yellow stigma. The flowering period is from May to June, and the fruiting period is from July to August. It was first mentioned in the ancient book *The Book of Songs*, indicating that the cultivation history of chestnut in China is at least 2,500 years. It is commonly cultivated in low-altitude hills, gentle slopes, and riverbanks.

[0003] Regarding the aforementioned technologies, the inventors believe that the detection of insect holes is a crucial quality control step in the processing of chestnuts. Traditional detection methods are not only inefficient but also easily affected by human factors, resulting in low detection accuracy. Furthermore, existing detection devices require chestnuts to be frozen before photographing and laser detection, followed by drying. Ensuring uniform drying of chestnuts after detection and avoiding localized over-drying or over-wetting is also key to improving chestnut quality.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0031] When the storage box 4 is moved below the defrosting plate 7, the hot air blower 17 will run for a period of time. At this time, airflow will be sprayed from multiple hot air nozzles 14, which will rapidly heat the solid ice in the storage box 4 and turn it into liquid water. Then, the staff can put the chestnuts without insect holes into the mesh box 9.

[0032] Reference Figure 1-4 The freezer includes a freezing plate 5 fixedly connected between two vertical plates 2.

The liquid water is cooled and freezes, freezing and fixing the chestnuts into the storage box 4. When the storage box 4 moves to below the detection plate 6, the lower end of the detection plate 6 is equipped with an industrial camera and a laser detection device to take pictures and analyze the chestnuts and perform laser scanning. Through the characteristics of the image, the size of the chestnut to be detected and the area of ​​suspected insect holes are obtained, and the chestnuts are detected and distinguished.

[0038] After the test is completed, when the storage box 4 is moved under the defrosting plate 7, the hot air blower 17 will run for a period of time. At this time, airflow will be sprayed from multiple hot air nozzles 14, which will rapidly heat the solid ice in the storage box 4 and turn it into liquid water. Then, the staff can put the chestnuts without insect holes into the mesh box 9 and start the circulating fan 12 and motor 10. When the circulating fan 12 is started, airflow will be sprayed through the hollow plate 8 and multiple fine holes 15 to dry the chestnuts evenly. At the same time, the dehumidification component 11 can ensure that the water vapor generated during the subsequent chestnut drying can be removed.

[0039] During the above process, the start of motor 10 will drive the mesh box 9 to rotate. The rotation of mesh box 9 will cause the chestnuts inside to rotate with mesh box 9, thereby achieving a more uniform drying effect.
