TECHNICAL FIELD
[0001] The utility model belongs to the processing technology field of cranberry, and specifically relates to a sorting device for cranberry. BACKGROUND
[0002] Cranberry is a kind of nutrient-rich berry, and the pulp contains rich proanthocyanidins, tannic acid, phenolic acid, resveratrol and other substances, and has antibacterial effect; in addition, flavonoids in cranberry have antioxidant function in in-vivo and in-vitro experiments, so it has been more and more popular among consumers. However, due to the production location restriction of cranberry and the high difficulty of shelf period and preservation, cranberry is more likely to enter the consumer's field of vision as cranberry dry and cranberry juice.
[0003] According to DB23 / T 3680-2024, cranberry is divided into four levels according to the size of the fruit, namely, extra-large fruit with a fruit diameter D greater than or equal to 2.0 cm, large fruit with a fruit diameter D greater than 1.5 cm but less than 2.0 cm, medium fruit with a fruit diameter D greater than 1.05 cm but less than 1.5 cm, and small fruit with a fruit diameter D less than 1.0 cm. The traditional method for grading cranberry fruit is to use a vibrating screen, but it can only separate cranberry of three sizes at most at one time, and it relies on manual feeding and taking, which is low in efficiency. Another sorting method is to make good fruit bounce higher than poor fruit, so the fruit falls from a funnel onto a device composed of inclined elastic plates, each plate has a door bar or a partition, and has two different heights; the fruit bouncing over the high door bar is the first grade, the fruit bouncing over the low door bar is the second grade, and the fruit not bouncing over both door bars is unqualified. However, it can still only separate cranberry of three sizes, and the fresh cranberry is easy to be damaged in the process of elastic sorting, causing unnecessary waste.
[0004] Chinese patent CN113182204A discloses a spherical fruit multi-level sorting device, which comprises a rack, a feeding box, a track inclinedly arranged below the discharge port of the feeding box for the fruit to roll along the track by gravity, an image capture device for capturing the external information of the fruit, an information processing system for receiving information, a fruit receiver arranged at the end of the track, and a screening device arranged downstream of the fruit receiver. The device can simultaneously realize size and shape quality screening, and can also simultaneously sort out fruits with good and bad shapes without manual additional sorting, thereby reducing labor intensity and improving work efficiency, and making the fruit sorting more accurate and efficient. However, it is only suitable for fruits with large fruit shape, such as apples, and has low efficiency, and is not suitable for sorting cranberry with small fruit shape and large volume.
[0005] The Chinese patent CN202079036U discloses a fruit sorting machine, which uses a tray mechanism, a transmission conveying device (a rack, etc.), a weighing mechanism and a controller to concentrate weighing, to obtain the weight of the fruit in each tray one by one, and the controller controls the classification overturning of each tray according to the weight information; when the tray mechanism with the fruit reaches the classification area, the controller controls the magnetic attraction and demagnetization of the electromagnetic suction disc by controlling the on-off of the power supply, so as to control the overturning of the tray mechanism, and the fruit is accurately sorted according to the weight. It has the advantages of simple structure, low equipment cost, convenient maintenance, reduced influence of vibration on dynamic weighing, and improved anti-interference ability of the production line.
[0006] However, the existing fruit sorting machines are only suitable for sorting medium and large fruits, rely on external identification devices or weighing devices, and cannot be well applied to the sorting of large amounts of cranberries in multiple levels. Therefore, it is necessary to design a sorting device suitable for cranberries to realize the multi-level sorting of cranberries. SUMMARY
