Description

Technical Field

[0001] This utility model relates to the technical field of cypress seed shell processing, specifically to a cypress seed shell screening and impurity removal device. Background Technology

[0002] The outer shell of cypress seeds is called cypress bark (also known as cypress bark coat). It is used as a spice in folk medicine. There is a saying that if you put cypress bark in a pillow, your white hair will turn black in six months. In addition, the aromatic gas of cypress bark has the effects of clearing heat and detoxifying, drying dampness and killing insects. Its main components are pinene and limonene. These natural substances can not only kill bacteria and viruses and purify the air, but also relax the mind and stabilize emotions.

[0003] In the processing of cypress seed shells, screening and impurity removal are required. A cypress seed shell screening and impurity removal device, such as one with patent publication number CN206366503U, uses a drive motor to rotate a rotating roller, which in turn drives a hard brush mounted on the roller. The opposing rotation of the rollers transports the accumulated cypress seed shells and seeds to the feeder. Simultaneously, the brushes separate the seeds from the shells by striking them. The brushes also remove dust and loose soil from the cypress seed shells, resulting in good feeding and separation effects. The design of the stirring rod further enhances the separation of seeds and shells. By combining the feeder and screening machine, the screening effect is effectively enhanced. The slag collection chamber collects the screened material.

[0004] However, the sieve of this device is inconvenient for collecting cypress seed husks, making it impractical. Utility Model Content

The outer ring side of the top of the outer cylinder 10 is connected to the bottom end of the externally threaded opening 11. The inner side of the outer cylinder 10 is detachably connected to the outer side of the collecting screen cylinder 12. The outer threaded opening 11 is detachably screwed to the inner threaded cover 9. The inner threaded cover 9 is connected to the output end of the collection guide 7 via the conveying pipe 8. The output end of the outer cylinder 10 is connected to the inner side of the exhaust pipe 14. An air pump 13 is installed on the exhaust pipe 14. The cypress seed shells are screened and impurities are removed in the sieve 1. The screened body is left on the upper surface of the filter screen 2. After screening, the slider 6 slides laterally inside the guide frame 5 by the driving mechanism. At the same time, the air pump 13 runs and exhausts air outward through the exhaust pipe 14. The air is connected to the outer cylinder 10 and the conveying pipe 8 to create a negative pressure at the bottom of the collection guide 7, which can suck in the cypress seed shells. The shells are then transported to the outer cylinder 10 via the conveying pipe 8 and collected by the collection screen 12. After completion, the inner threaded cover 9 can be rotated and screwed off outside the outer threaded opening 11, and then the collection screen 12 can be taken out and emptied.

[0025] The drive mechanism includes a reciprocating motor 15, a transverse screw 16, and a threaded sleeve 17. The outer side of the right support plate 4 is connected to the inner side of the reciprocating motor 15, and the output end of the reciprocating motor 15 is connected to the right side of the transverse screw 16. The transverse screw 16 is rotatably connected inside the guide frame 5. The inner side of the slider 6 is connected to the outer side of the threaded sleeve 17, and the inner wall of the threaded sleeve 17 is screwed to the outer wall of the transverse screw 16. When the reciprocating motor 15 runs, the transverse screw 16 can rotate. The transverse screw 16 can be connected to the threaded sleeve 17 and the slider 6 can be moved transversely.

[0026] It also includes an oil injection nozzle 18, with the upper left side of the outer side of the threaded sleeve 17 connected to the inner side of the oil injection nozzle 18; oil can be injected into the inner wall of the threaded sleeve 17 through the oil injection nozzle 18 for convenient lubrication and maintenance.

[0030] In summary, when using a cypress seed shell screening and impurity removal device, the cypress seed shells are screened and impurities removed inside the screening unit 1. The screened shells remain on the upper surface of the filter screen 2. After screening, the reciprocating motor 15 rotates the transverse screw 16. The transverse screw 16 is screwed into the threaded sleeve 17, causing the slider 6 to slide laterally inside the guide frame 5. At the same time, the air pump 13 runs, exhausting air outward through the exhaust pipe 14. This air is connected to the outer cylinder 10 and the conveying pipe 8, creating a negative pressure at the bottom of the collecting guide 7, which draws in the cypress seed shells, which are then transported through the conveying pipe 8. The contents are collected in the outer cylinder 10 by the collecting screen cylinder 12. After collection, the inner threaded cover 9 can be rotated by squeezing the handle 21 to remove it from the outer threaded opening 11. The collecting screen cylinder 12 can then be removed and emptied. In addition, oil can be injected into the inner wall of the threaded sleeve 17 through the oiling nozzle 18 for convenient lubrication and maintenance. An oiling cap 19 can be installed on the outside of the oiling nozzle 18 to seal and protect the inside of the oiling nozzle 18. The observation window 20 allows for observation from the outside to the inside, making it easy to judge the collection status in the collecting screen cylinder 12 and handle it in a timely manner, thus improving convenience.
