Generally speaking, blueberry fruits can be divided into several grades, such as special grade, first grade, and second grade. The specific grading standards may vary depending on factors such as region, variety, and market demand. When grading blueberry fruits, special grading equipment is usually used, such as a blueberry grader. These devices use mechanical or machine vision technology to automatically sort and classify blueberries according to their size, color, shape and other characteristics. The graded blueberry fruits can better meet market demand and increase the added value of the product.

[0003] At present, existing grading devices usually sort blueberries according to their volume size. They use grids or gaps of different sizes to allow blueberry fruits to move along the grading screen.

In this way, through the difference in gap size, the device can screen out blueberries of different grades in turn. However, the grading gap of this grading device cannot be adjusted at will, and blueberries are easily stuck in the sorting gap or the surface of the fruit is damaged due to collision.

[0024] According to the above disclosure of the specific structure of the rotating assembly 22, the rotating assembly 22 includes two rotating plates 220, and the two rotating plates 220 are respectively movably connected between the outer walls of the convex rods between the two convex plates 211 opposite to each other between the two slide plates 210. A rotating rod 221 is fixedly connected at the center of one of the rotating plates 220, and the other rotating plate 220 is movably connected to the outer wall of the rotating rod 221. The bottom of the rotating rod 221 is fixedly connected to the motor output shaft. The rotating assembly 22 is used to adjust the distance between the two slide plates 210. The rotating rod 221 is electrically driven by the motor output shaft to rotate, and the rotating rod 221 drives one of the rotating plates 220 to rotate, thereby adjusting the angle between the two rotating plates 220.
