It is rich in various nutrients, including vitamins, minerals and various bioactive substances, and has high medicinal and nutritional value. The processing of black wolfberry mainly includes several steps such as harvesting, grading and drying.

[0003] However, in the current prior art, when black wolfberries are graded and screened, the fresh black wolfberries are generally screened according to the size of the fresh fruits through a plurality of sieve plates of different sizes. When the fresh fruits roll through the sieve plates, the smaller fresh fruits will fall directly from the sieve plates, while the larger ones will slide to one side on the sieve plates for collection. However, since the surface of the black wolfberries is not round, the sliding speed of the fresh fruits is relatively slow, causing the fresh fruits at the rear to collide with the fresh fruits sliding in the front, and the fresh fruits will be squeezed into the slits of the sieve plates and stuck, thereby causing the sieve plates to be blocked, and the squeezed fresh fruits will be damaged, affecting the quality.

[0006] As a preferred solution of the utility model, multiple installation frames are connected to the inner wall of the shell by bolts, and multiple collection boxes are connected to the outer wall of the shell by bolts. The inner wall of the shell is provided with a discharge hole at the installation frame, and the collection box corresponds to the position of the discharge hole.

[0007] As a preferred solution of the utility model, the inclined plate is integrally formed with the inner wall of the drop chute, and the drop chute is a through structure, so that the fresh fruit can be discharged by rolling through the inclined plate.

[0008] As a preferred solution of the utility model, the plurality of sliding bars are rotatably connected to the inner wall of the drop groove through a connecting shaft. In the normal state, the sliding bar is in a locked state, and its rotation can be controlled by a PLC controller. The induction plate is embedded and connected to the outer wall of the sliding bar, and the induction plate is electrically connected to the connecting shaft.

[0009] As a preferred solution of the utility model, the through groove is an inclined structure and communicates with the drop groove, the drive shaft is rotatably connected to the inner wall of the through groove through a bearing, and the fan blade sleeve is arranged outside the drive shaft and coaxially connected to the drive shaft.

[0010] As a preferred solution of the utility model, the inclination angle of the through groove corresponds to the slide bar in the drop groove, and the wind force generated by the rotation of the fan blades can be blown out through the gaps between the slide bars to accelerate the rolling speed of the fresh fruit.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: in response to the problems raised in the background technology, the present application adopts an auxiliary component, which can screen the fresh black wolfberry fruits by size through the gaps between the sliding bars in the installation frame, and when the fresh fruit slides on the sliding bar, the angle of the through groove in the falling groove is toward the front end of the sliding bar, and the airflow is generated by the rotation of the fan blades and blown to the sliding bar. When the airflow passes through the gap of the sliding bar, it is blown to the fresh fruit, thereby increasing the sliding speed of the fresh fruit, preventing the fresh fruit from piling up and giving the fresh fruit an upward thrust to prevent the fresh fruit from being stuck in the gap of the sliding bar; after the fresh fruit is stuck in the gap of the sliding bar and causes a blockage, the fresh fruit will abut against the induction plate on the outer wall of the sliding bar, and the blockage is detected by the induction plate, and the rotation of the sliding bar is controlled to push the fresh fruit out, thereby preventing the fresh fruit from being blocked again.

[0012] The utility model realizes that airflow accelerates the sliding speed of fresh fruits, prevents fruits from colliding and piling up, accelerates the screening speed, can push fresh fruits upward by airflow to reduce the probability of blockage, can detect and discharge fresh fruits when they are piled up, ensures the screening effect, and reduces the breakage rate of fresh fruits.
