Technical Field
[0001] This utility model relates to the field of wolfberry screening technology, and more specifically to a wolfberry classification and screening device. Background Technology
[0002] Goji berries belong to the Solanaceae family and the Lycium genus. The term "goji berry" is a general term encompassing commercially available goji berries, as well as various species within the Lycium genus such as Ningxia goji berries and Chinese goji berries. Goji berries are suitable for everyone and offer numerous health benefits, including boosting immunity, regulating metabolism and anti-aging, lowering blood lipids and blood sugar, improving eyesight, and beautifying the skin. They are increasingly favored by consumers. To differentiate the quality of goji berries, they are sorted and graded according to size after harvesting.
[0003] Existing screening devices generally use round or square holes for screening. Since goji berries are ellipsoidal in shape, they are prone to clogging the round or square holes, resulting in low screening efficiency and poor screening effect. Utility Model Content
[0004] The purpose of this invention is to provide a goji berry classification and screening device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides a goji berry sorting and screening device, including a support frame. Two supports are provided, each with a fixed support ring. A screening cylinder is rotatably mounted between the two support rings. The screening cylinder has multiple elongated sieve holes on its surface. A support shaft is fixedly mounted on the outer wall of the screening cylinder. A support block is fixedly mounted on the upper end of each of the two support rings. A motor is fixedly mounted on one of the support blocks. A rotating shaft is rotatably mounted between the two support blocks. The output end of the motor is fixed to the rotating shaft. A gear assembly for driving the support shaft to rotate is mounted on the rotating shaft. A scraping mechanism is provided inside the screening cylinder. The scraping mechanism includes a reciprocating screw, which is rotatably mounted inside the screening cylinder. A threaded sleeve is threaded onto the reciprocating screw. A scraper plate is fixedly mounted on the upper end of the threaded sleeve, and the scraper plate contacts the inner wall of the screening cylinder. A transmission assembly for driving the reciprocating screw to rotate is mounted on the rotating shaft.
[0006] As a further improvement to this technical solution, the surface of the screening cylinder is provided with an opening, a cover plate is provided inside the opening of the screening cylinder, and an mounting plate is fixedly provided on the side of the cover plate. The mounting plate is connected and fixed to the screening cylinder by bolts.
[0007] As a further improvement to this technical solution, the gear assembly includes a first gear and a second gear. The first gear is fixedly mounted on a rotating shaft, and the second gear is fixedly mounted on a support shaft. The first gear and the second gear are meshed together.
[0008] As a further improvement to this technical solution, a collection hopper is fixedly arranged between the two supports, the collection hopper is located below the screening cylinder, and a discharge port is provided at the bottom of the collection hopper.
[0009] As a further improvement to this technical solution, the transmission assembly includes a driving wheel, a driven wheel, and a belt. The driving wheel is fixedly mounted on a rotating shaft, and the driven wheel is fixedly mounted on a reciprocating lead screw. The driving wheel and the driven wheel are connected by a belt drive.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] 1. By setting up a screening cylinder, the motor drives the rotating shaft to rotate, the rotating shaft drives the first gear to rotate, the first gear drives the second gear to rotate, the second gear drives the support shaft to rotate, the support shaft drives the screening cylinder to rotate, and the screening cylinder causes the goji berries to tumble, so that the screening cylinder rotates to screen. The goji berries are screened through the long strip-shaped sieve holes. Because the long strip-shaped sieve holes are closer to the shape of the goji berries, the goji berries are less likely to clog the sieve holes.
[0012] 2. By setting up a scraping mechanism, the rotating shaft drives the drive wheel to rotate, which in turn drives the screw sleeve to move back and forth along the reciprocating screw. The screw sleeve drives the scraper plate to move back and forth, scraping off large goji berries stuck in the screen holes, thus preventing large goji berries from clogging the screen holes and improving screening efficiency.

The surface of the screening cylinder 3 has an opening, and a cover plate 10 is provided inside the opening of the screening cylinder 3. The side of the cover plate 10 has an opening. A mounting plate 11 is fixedly installed and connected to the screening cylinder 3 by bolts. Goji berries are added into the screening cylinder 3 by opening the cover plate 10. After screening, the cover plate 10 is rotated to the downward position and the cover plate 10 is opened to pour out the goji berries in the screening cylinder 3. A collection hopper 14 is fixedly installed between the two supports 1. The collection hopper 14 is located below the screening cylinder 3 and has a discharge port at the bottom. Goji berries are screened through multiple sieve holes 4. Small goji berries pass through the sieve holes 4 and are discharged outside the screening cylinder 3 and collected by the collection hopper 14. Large goji berries are retained inside the screening cylinder 3.
[0022] A support shaft 5 is fixedly installed on the outer wall of the screening cylinder 3. Support blocks 6 are fixedly installed on the upper ends of the two support rings 2. A motor 7 is fixedly installed on one of the support blocks 6. A rotating shaft 8 is rotatably installed between the two support blocks 6.

The screening cylinder 3 causes the goji berries to tumble, thus rotating the screening cylinder 3 to perform screening and improve the screening effect.
[0023] A scraping mechanism 9 is provided inside the screening cylinder 3. The scraping mechanism 9 includes a reciprocating screw 91, which is rotatably mounted inside the screening cylinder 3. A threaded sleeve 92 is threaded onto the reciprocating screw 91, and a scraper plate 93 is fixedly mounted on the upper end of the threaded sleeve 92.

The driving wheel 94 drives the driven wheel 95 to rotate through the belt 96. The driven wheel 95 drives the reciprocating screw 91 to rotate, which in turn drives the screw sleeve 92 to move back and forth along the reciprocating screw 91. The screw sleeve 92 drives the scraper plate 93 to move back and forth. The scraper plate 93 scrapes off the large goji berries stuck in the screen holes 4, preventing the large goji berries from clogging the screen holes 4.
[0024] The specific working principle of this utility model is as follows: Goji berries are added into the screening cylinder 3 by opening the cover plate 10. The motor 7 drives the rotating shaft 8 to rotate, which in turn drives the first gear 12 to rotate. The first gear 12 drives the second gear 13 to rotate, which in turn drives the support shaft 5 to rotate. The support shaft 5 then drives the screening cylinder 3 to rotate, causing the goji berries to tumble. This rotation of the screening cylinder 3 facilitates screening. Small goji berry particles pass through the sieve holes 4 and are discharged outside the screening cylinder 3, where they are collected by the collecting hopper 14. Larger goji berry particles are retained inside the screening cylinder 3. The elongated sieve holes 4 screen the goji berries. Because the elongated sieve holes 4 are closer to the shape of the goji berries, the goji berries are less likely to clog the sieve holes 4. The rotating shaft 8 simultaneously drives the drive wheel 94 to rotate. The drive wheel 94 drives the driven wheel 95 to rotate through the belt 96. The driven wheel 95 drives the reciprocating screw 91 to rotate, which in turn drives the screw sleeve 92 to move back and forth along the reciprocating screw 91. The screw sleeve 92 drives the scraper plate 93 to move back and forth. The scraper plate 93 scrapes off the large goji berries stuck in the sieve holes 4, preventing large goji berries from clogging the sieve holes 4 and improving screening efficiency.
