Fruit grading machine

Abstract

The invention discloses a fruit grading machine. The fruit grading machine comprises a grading machine body, the front end of the grading machine body is fixedly provided with a feeding groove, and abase is fixedly arranged at the position, under the feeding groove, of the front end of the grading machine body; and a screening roller is rotationally arranged on the inner side of the grading machine body, and a dehumidification plate is fixedly arranged at the upper end of the grading machine body. According to the fruit grading machine, an inner cover is added to the inner side of the screening roller, the diameters of leakage holes of an outer cover is changed through arranging leakage holes with different diameters in the inner cover, and thus the application range of the grading machine is expanded; falling force generated by falling of fruits can be relieved through a net bag and a buffering net bag on a pulling plate, and thus the falling force generated by falling can not causedamage to the outer surface of the fruits; and the fruits needing to be graded can be cleaned conveniently through a cleaning groove, the cleaned fruits can be wiped conveniently through cooperation with the dehumidification plate, and thus water drops on the surfaces of the fruits can be conveniently removed, and the cleanness of the surfaces of the fruits can be kept.

Description

technical field [0001] The invention relates to the technical field of fruits, in particular to a fruit grader. Background technique [0002] General fruit grading machinery can be divided into size grading machine, weight grading machine and fruit color grading machine according to the working principle. The size and shape of the fruit selected by the size grading machine are basically the same, which is conducive to packaging, storage and processing. The most widely used in walnut grading, this method is used, [0003] However, when a fruit classifier currently on the market classifies materials, it will have an impact on the fruit, and in the process of material falling, its own posture is random, which is likely to cause low classification accuracy, and it is suitable for fruits of different sizes. When grading, the hole size of the same grading machine is limited, so it is not suitable for fruits of different shapes and sizes, such as satsuma and apple. The difference ...

Problems solved by technology

[0003] However, when a fruit classifier currently on the market classifies materials, it will have an impact on the fruit, and in the process of material falling, its own posture is random, which is likely to cause low classification accuracy, and it is suitable for fruits of different sizes. When grading, the hole size of the same grading machine is limited, so it is not suitable for fruits of different shapes and sizes, such as satsuma and apple. The difference between the two sizes is too large, and the same grading machine cannot grade them. Moreover, when grading fruits, the dust and debris on the fruits will easily fall into the screening rollers during the fruit grading process. Long-term use will easily cause blockage of the screening leaks, which not only affects the use of the screening rollers, but also affects the cleanliness of the fruits.
