Description

Technical Field

[0001] The utility model relates to the technical field of apple processing, and particularly relates to a screening device for apple processing. Background Art

[0002] Apples are deciduous arbor plants of the genus Malus in the Rosaceae family. They have relatively tall trunks, short and thick branches that are cylindrical; their leaves are oval-shaped, with smooth surfaces, serrated edges, and thick petioles; their flowers are small, in an umbrella shape, light pink, with fluff on the surface; their fruits are relatively large, oblate, and the fruit stalks are short and thick; the flowering period is in May; the fruiting period is from July to October.

[0003] During the screening process of traditional apple processing screening devices, the apples are flipped too much, and the apples are easily scratched and impacted when they fall, resulting in damage to the appearance of the apples.

[0004] After retrieval of existing Chinese patents: A screening device for apple processing (publication number: CN209829573U), which includes roller shafts. There are four roller shafts, and a conveyor belt is sleeved outside the 4 roller shafts. The conveyor belt is distributed in a rectangle, and a collecting cloth is correspondingly arranged below the top edge of the conveyor belt. Both ends of the collecting cloth are respectively connected to support rods, and the length of the collecting cloth is greater than the distance between the support rods. And the side view of the collecting cloth is trapezoidal. Circular through holes are evenly distributed on the conveyor belt, and protective sleeves are distributed around the edges of the through holes. The inner wall of the protective sleeve is arc-shaped. One end of the conveyor belt is provided with an inclined first collecting groove, and the top height of the first collecting groove is flush with the top height of the conveyor belt. This apple processing screening device adopts a horizontal conveyor belt structure design, which can reduce the rolling of apples during the screening process. And through the structures of the protective sleeve and the collecting cloth, the scratching and impact on the apples can be reduced, thereby preventing damage to the appearance of the apples.

[0005] Although the above patent adopts a horizontal conveyor belt structure design, which can reduce the rolling of apples during the screening process, and through the structures of the protective sleeve and the collecting cloth, the scratching and impact on the apples can be reduced, thereby preventing damage to the appearance of the apples, the disadvantage of this device is that it is impossible to accurately know whether the collecting cloth is full of apples. This requires workers to guard the collecting device, and at the same time, it takes effort for workers to take out the full collecting device from the machine, making the operation laborious and not very convenient.

[0006] Therefore, it is very necessary to invent a screening device for apple processing to solve the above problems. Utility Model Content

Another empty collection box is placed on the tray. When the full collection box moves out, the empty collection box moves into the screening frame to continue receiving materials, and the full collection box automatically moves out, which is convenient for workers to carry. Thus, the device achieves the effect of automatic discharging, eliminating the need for workers to observe in real time whether the collection box is full, reducing the labor burden of workers, and improving work efficiency.

The medium-aperture screening cylinder is fixed on the outer wall of the driving main shaft, and the medium-aperture screening cylinder can screen medium-sized apples. The first pulley set and the second pulley set are fixed on the outer wall of the driving main shaft, so that the driving main shaft drives the first pulley set and the second pulley set to rotate. The first driven shaft is fixed inside the first pulley set, and the small-aperture screening cylinder is fixed on the outer wall of the first driven shaft. The second driven shaft is fixed inside the second pulley set, and the large-aperture screening cylinder is fixed on the outer wall of the second driven shaft.

Thus, the device achieves the effect of classification and screening. BRIEF DESCRIPTION OF THE DRAWINGS
