Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, and in particular to a sieving device for fine tea processing. Background Technology

[0002] Tea processing is the process of turning tea leaves (fresh leaves) into finished tea products through a series of techniques. The key steps in tea processing include picking, withering, fixing, rolling, drying, fermentation, and screening. Different types of tea (such as green tea, black tea, white tea, oolong tea, etc.) may have different processing focuses. For example, green tea focuses on maintaining the green color of the original leaves, while black tea requires a higher degree of fermentation.

[0003] After processing, tea leaves undergo screening to remove impurities and are graded according to quality, appearance, etc., before final packaging. Current tea screening devices typically rely on a single screen or simple sieve cylinder, making multi-stage screening difficult. This results in low screening accuracy, ineffective removal of impurities and fine particles, and cumbersome collection and emptying systems that often require multiple manual handling and emptying operations. Cleaning the device is also troublesome, and tea fragments and impurities easily remain, affecting subsequent use. Therefore, this invention proposes a tea screening device for refined tea processing to solve the problems mentioned in the background section. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sieving device for the fine processing of tea.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A sieving device for tea refining includes a device base, a vertical seat fixedly installed on one side of the device base, a sliding seat that slides left and right on the front side of the vertical seat, a rotating block rotatably connected to the upper side of the sliding block, a bearing seat rotatably connected to the outer side of the rotating block, a sieve cylinder rotatably connected to the bearing seat, a plurality of sieve cylinders being evenly arranged vertically on the device base, a collection cover fixedly installed on the device base below the sieve cylinders, a bracket fixedly installed on the lower side of the collection cover, a collection box being provided inside the bracket, and a corresponding locking block being provided at the other end of the sieve cylinders, the locking block being rotatably connected to the device base.

[0006] Preferably, a number of motors are fixedly installed on the outside of the device base, and the output shafts of the motors are fixedly connected to a number of locking blocks. The slots for the corresponding collection boxes are opened in the center of the inner side of the locking blocks.

[0007] Preferably, the length of the sieve cylinder is less than the length of the collection cover, the filter diameter of the filter holes of the sieve cylinders is different, and the other end of the sieve cylinder is provided with a number of slots corresponding to the card blocks.

[0008] Preferably, a limiting groove is provided on the lower side of the collection box, an open through groove corresponding to the shape of the collection box is provided at one end of the sieve cylinder, and a through groove corresponding to the collection box and the limiting groove is provided inside the bracket.

[0009] Preferably, a limiting block is provided above each of the slide blocks, and the limiting block is rotatably connected to the vertical seat.

[0010] Preferably, the rear side of the slide block is provided with several limiting grooves corresponding to the limiting blocks.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model can achieve multi-stage screening by using the difference in the diameter of the filter holes of multiple sieve cylinders, which can finely screen tea leaves, remove impurities and small particles, and improve the quality of tea leaves. The tea leaves inside the sieve cylinder are screened by rotation, and larger tea leaves are retained in the sieve cylinder, while smaller debris is screened out. 2. The collection cover and collection box in this utility model design enable tea leaves to be quickly transferred to different sieve cylinders for further sieving. The detachment system between the sieve cylinder and the collection box simplifies the operation, facilitates the quick pouring out of the sieved tea leaves, and improves the tea sieving efficiency. The device is easy to operate and clean, and the sieve cylinder design has good adjustability and adaptability, making it suitable for different tea leaves and sieving needs.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-5 A tea sieving device includes a device base 1, a vertical seat 6 fixedly installed on one side of the device base 1, a sliding seat 7 that slides left and right on the front side of the vertical seat 6, a rotating block 16 rotatably connected to the upper side of the sliding seat 7, a bearing seat 8 rotatably connected to the outer side of the rotating block 16, and a sieve cylinder 2 rotatably connected to the bearing seat 8. Several sieve cylinders 2 have different filter apertures for screening. Tea leaves are loaded into the sieve cylinders 2, and the rotating sieve cylinders 2 achieve rotational screening of the tea leaves inside. Tea leaves with larger particle sizes remain inside the sieve cylinders 2, while particulate impurities and smaller tea leaves are screened out inside the sieve cylinders 2. This device can achieve multi-stage screening of tea leaves, resulting in more layers of tea leaves and achieving fine screening of tea leaves. Several sieve cylinders 2 are evenly arranged vertically on the device base 1. A collection cover 3 fixed to the device base 1 is set below the sieve cylinders 2. A bracket 13 is fixedly installed on the lower side of the collection cover 3. A collection box 4 is set inside the bracket 13. The length of the sieve cylinder 2 is less than the length of the collection cover 3. A limiting groove 14 is opened on the lower side of the collection box 4. An opening groove corresponding to the shape of the collection box 4 is opened at one end of the sieve cylinder 2. A groove corresponding to the shape of the collection box 4 and the limiting groove 14 is opened inside the bracket 13. The collection box 4 cooperates with the upper collection cover 3 to collect the tea leaves screened by the upper rotating sieve cylinder 2. The full collection box 4 is pulled out and put into another sieve cylinder 2. The collection box 4 is inserted into the sieve cylinder 2 through the opening groove of the corresponding shape at one end of the sieve cylinder 2, so that the tea leaves after screening can be put back into another sieve cylinder 2, realizing multi-stage screening of tea leaves for rapid transfer. The other end of the sieve cylinder 2 is provided with a corresponding locking block 9, which is rotatably connected to the device base 1. Several motors 5 are fixedly installed on the outside of the device base 1. The output shafts of the motors 5 are fixedly connected to the locking blocks 9. The center of the inner side of the locking block 9 is provided with a slot 10 corresponding to the collection box 4. The collection box 4 inserted into the sieve cylinder 2 has one end inserted into the slot 10 corresponding to the center of the inner side of the locking block 9, so that the collection box 4 is stably inserted into the sieve cylinder 2. The other end of the sieve cylinder 2 is provided with several slots 15 corresponding to the locking block 9. Several sliding blocks 7 are provided with a limiting block 11, which is rotatably connected to the vertical base 6. Several limiting slots 12 corresponding to the limiting block 11 are provided on the rear side of the sliding block 7. When the motor 5 on one side of the device base 1 is started, the output shaft of the motor 5 drives the connected locking block 9 to rotate. The locking block 9 cooperates with the sieve cylinder 2 matching the slot 15, and the rotation of the sieve cylinder 2 between the device base 1 and the vertical base 6 is realized, thereby realizing the rotation of the sieve cylinder 2 to screen tea leaves. After the tea leaves are sieved by the rotating sieve cylinder 2, the tea leaves inside the sieve cylinder 2 need to be poured out. First, rotate the limiting block 11 above the slide block 7 of the sieve cylinder 2, and then slide the slide block 7 structure of the sieve cylinder 2 outward a certain distance, so that the locking block 9 disengages from the locking groove 15 at the other end of the sieve cylinder 2. Then, rotate the bearing seat 8 upward a certain angle, so that the sieve cylinder 2 disengages from the corresponding collection cover 3 below. Rotate the rotating block 16 on the slide block 7 a certain angle, so that the sieve cylinder 2 rotates out of the device seat 1. The sieve cylinder 2 is no longer in the upper range of the lower collection cover 3. Then, rotate the bearing seat 8 on the rotating seat 16 downward, so that the outlet on the side of the locking groove 15 at the other end of the sieve cylinder 2 faces downward, thereby realizing the collection of tea leaves inside the sieve cylinder 2.

[0016] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
