Description

Technical Field

[0001] The utility model relates to the technical field of pepper processing, in particular to a dry pepper screening device. Background Art

[0002] Pepper is an important vegetable and condiment, and its fruit has the medicinal effect of expelling insects and sweating. At present, making fresh pepper into dried pepper is a common processing method, which can facilitate the storage of pepper.

[0003] In the production of dried chili peppers, it is inevitable that some impurities such as dust and gravel will be mixed in (such as dried chili peppers collected from farmers' homes, etc.), and in the temporary storage process of dried chili peppers, some hair may be mixed in the dried chili peppers (because the peppers are usually stored in feed bags, and the bag openings of feed bags are easy to remove hair, so it is easy for hair to fall into the peppers). At this time, in order to ensure the quality of dried chili peppers, impurities such as hair, gravel and dust need to be discharged through screening devices.

[0004] After searching, it was found that patent numbers CN202121724699.8 and patent number CN202320292239.5 both disclosed some dry chili screening devices, the basic principle of which is to use an air separator to select the dry chili. Although this method can discharge the dust mixed in the dry chili, some larger feed pocket hairs are easily mixed in the dry chili, which is inconvenient to discharge, and heavier impurities such as gravel cannot be discharged, resulting in low screening quality. Utility Model Content

[0005] Therefore, in order to solve the above-mentioned shortcomings, the utility model provides a dry chili screening device, which arranges a sieve plate in the screening frame, and the sieve plate divides the screening frame into two upper and lower areas. For different discharge ports, the gravel mixed in the dry chili can be discharged separately by setting a bottom vibration device (if gravel cannot pass through the sieve plate, it is necessary to screen it out manually or use a fan with a larger air volume for further screening). Then, the first cleaning component in the protective shell can be used to turn over the dry chili on the sieve plate to prevent some hair from being pressed by the dry chili and unable to be discharged. The longer hair can be wrapped by a soft brush, and finally the shorter hair can be cleaned by combining the soft Velcro on the second cleaning component, thereby effectively improving the screening quality.

[0030] As described in the background technology, the existing screening device only screens the dried peppers through a winnowing machine, which can only blow out the dust in the dried peppers, but cannot screen out the gravel and some hair mixed inside, and thus cannot guarantee the screening quality.

[0031] For the reasons stated above, please refer to the attached Figure 1 The utility model provides a dry chili screening device, comprising a screening frame 3, which is mounted on a support frame 1 through an elastic member 2 and has two discharge ports on the screening frame 3;

[0032] The sieve plate 4 is fixed in the screening frame 3 and extends to the discharge port at the outer end, dividing the interior of the screening frame 3 into two upper and lower areas, and the two discharge ports correspond to the two areas respectively;

[0033] A vibration device 5 is arranged at the bottom of the screening frame 3 to drive the screening frame 3 to vibrate;

[0034] The first cleaning component is rotatably arranged above the screening frame 3 to facilitate turning over and removing impurities from the materials in the screening frame 3;

[0035] The protective shell 6 is sleeved on the outside of the cleaning component to prevent the turned materials and debris from flying out, and an opening and closing plate 8 is movably provided on the protective shell 6 to facilitate cleaning of the cleaning component;

[0036] The second cleaning component is arranged on the screening frame 3 outside the protective shell 6 and close to the discharge port.

[0037] Specifically, the sieve plate 4 is horizontally mounted on the inner wall of the screening frame 3 by fasteners, and any end of the sieve plate 4 is arranged above any discharge port of the screening frame 3, while the sieve plate 4 blocks the other discharge port.

[0038] Through the above technical features, the installation method of the sieve plate is set to facilitate the screening of the dried chilies, and the crushed stones pass through the sieve holes of the sieve plate and are discharged from the discharge port below the sieve plate, while the dried chilies are discharged from the discharge port above the sieve plate, thereby achieving the removal of crushed stones and other heavier impurities.

[0039] Specifically, the first cleaning component is a rotating rod 11 and a cleaning roller 13 mounted on the rotating rod 11 at the inner end of the screening frame 4. The rotating rod 11 passes through the protective shell 6 arranged above the screening frame 3 and maintains a rotational connection therewith. A transmission wheel 12 is also provided on the rotating rod 11 at the outer end of the protective shell 6. Soft brushes are evenly arranged on the outer end of the cleaning roller 13, and the end of the soft brush remains in contact with the screen plate 4.

[0040] Through the above-mentioned technical features, the specific structure of the first cleaning component can facilitate contact with the dry peppers on the screen plate and flip upwards, thereby preventing some hairs from being pressed by the dry peppers and unable to be screened out. The soft brushes evenly distributed on the outer end of the rotating rod can roll up the longer hairs, thereby achieving hair removal.

[0041] Specifically, the protective shell 6 is in a semi-cylindrical shape, and its plane is fixed on the screening frame 4. A debris discharge port is opened at the top of the protective shell 6 and a negative pressure hose 7 is installed at the debris discharge port. The negative pressure hose 7 draws out the air in the protective shell 6 through an external negative pressure device. Cleaning ports are opened on both sides of the curved surface of the protective shell 6, and an opening and closing plate 8 is movably installed at the cleaning port. The opening and closing plate 8 is a curved plate that is kept in contact with the curved surface of the protective shell 6.

[0042] Through the above technical features, the negative pressure hose arranged on the protective shell can extract the dust mixed in the dry peppers, and at the same time can absorb a part of the hair to remove the dust in the dry peppers, so as to facilitate the removal of dust in the dry peppers.

[0043] Specifically, sliding slots are provided along the arc-shaped surfaces on the inner ends of the protective shell 6 on both sides of the cleaning port, and the opening and closing plate 8 is clamped in the sliding slots and slides in the sliding slots.

[0044] Through the above technical features, the sliding slot in the protective shell is provided to facilitate the installation of the opening and closing plate, and to facilitate the sliding of the opening and closing plate, thereby realizing opening and closing.

[0045] Specifically, the second cleaning component includes a mounting rod 9 and a soft Velcro 10. The mounting rod 9 is installed above the screening frame 4 through a mounting block. One end of the soft Velcro 10 is fixed on the mounting rod 9, and the other end naturally hangs down and falls into the screening frame 4.

[0046] Specifically, the side of the soft Velcro 10 facing the protective shell 6 is bristles with hooks.

[0047] Through the above-mentioned technical features, the specific structure of the second cleaning component is set to facilitate the adhesion of small unremoved hair through Velcro, thereby achieving further screening and effectively improving the screening quality.

[0048] When the screening device screens the dried chili peppers, the transmission wheel 12 is first connected to the external drive motor to drive the rotating rod 11 to rotate (in order to prevent the transmission wheel and the transmission belt of the drive motor from falling off when the screening frame vibrates, the drive motor can be installed on the protective housing to keep the drive motor vibrating with the screening frame, thereby effectively preventing it from falling off), and the rotation direction is ensured to be consistent with the conveying direction of the dried chili peppers in the screening frame 3 as much as possible (that is, when the conveying direction is to the right, the rotation direction is clockwise), so as to facilitate the dry chili peppers to be thrown upward to achieve flipping, and then the vibration device 5 (that is, the vibration motor) is started to drive the screening frame 3 to vibrate on the support frame 1.

[0049] Then start the external negative pressure device, and generate negative pressure in the protective shell 6 through the negative pressure hose 7 to absorb the dust. At this time, the dry pepper can be poured into the screening frame 3 and dropped on the sieve plate 4. Under the vibration of the screening frame 3, the dry pepper on the sieve plate 4 moves to one side, and the gravel passes through the sieve holes of the sieve plate 4 and is discharged from the discharge port below the sieve plate. After entering the protective shell 6, it is flipped upward by the cleaning roller 13 of the rotating rod 12. At the same time, the soft brush on the cleaning roller 13 cleans the dust adhered to the dry pepper, which is then absorbed out by the negative pressure hose 7. At the same time, part of the hair will be absorbed out, and then the dry pepper passes through the rotating rod 11 and moves toward the soft Velcro 10 until the remaining hair is adhered out after passing through the soft Velcro 10. Finally, it is discharged from the discharge port at the end of the sieve plate 4 after multiple impurities removal.

[0050] After the final screening is completed, turn off the vibration device 5 and the driving motor, etc., open the opening and closing plate 8 to remove the hair entangled on the cleaning roller 13, and at the same time remove the hair on the soft Velcro 10, so as to facilitate subsequent use.

[0051] The above description is a detailed description of the preferred feasible embodiment of the utility model, but the embodiment is not used to limit the scope of the patent application of the utility model. All equivalent changes or modified changes completed under the technical spirit suggested by the utility model should fall within the patent scope covered by the utility model.
