Description

Technical Field

[0001] The utility model relates to the technical field of tea screening, in particular to a screening box with the function of collecting tea leaves in layers. Background Art

[0002] Tea processing, also known as "tea making", is the process of making various semi-finished teas or finished teas through various processing procedures for fresh tea leaves. According to the different processing procedures, it can be divided into primary processing (primary processing), refining (fine processing), reprocessing and deep processing. Different processing techniques will form different types of tea. The formation of the quality of each type of tea depends on the coordination of the processing procedures. High-quality fresh leaf raw materials can only produce various high-quality teas under excellent processing conditions. Since the collected tea leaves are of different sizes and shapes, the grades of the products are also different, so the tea leaves must go through a screening process before production.

[0003] Traditionally, tea leaves are screened directly using screens. If multi-layer screening is required, multiple screens are used in combination to screen out tea leaves of different sizes. However, tea leaves are easy to accumulate and stick together. When vibrating and screening in the screen, the efficiency is slow. If a stirring rod is added during the vibration screening process to break up and screen, the tea leaves will be damaged during the breaking process, thereby reducing the quality of the tea leaves. Therefore, traditional screening mechanisms have certain disadvantages in actual use. Utility Model Content

Therefore, during the rotation of the tea leaves in the second filter cartridge 33, the smaller tea leaves and the debris will fall into the first filter cartridge 32. The first filter cartridge 32 is also rotating, so the first filter cartridge 32 can leak the debris into the outer cylinder 31, so that the smaller tea leaves remain in the first filter cartridge 32. In this way, the tea leaves can be screened into three parts: larger, smaller and debris, which is convenient for layered collection of the tea leaves. The sealing plate 6 can be set to intercept the tea leaves in the screening cylinder 3 during the screening process. After the screening is completed, the function of collecting tea leaves of different parts can be realized by opening different sealing blocks 5, which is convenient for operation and use. Moreover, this rotation method can protect the tea leaves and prevent the tea leaves from being seriously damaged.

[0029] Furthermore, two annular grooves 61 are provided on the side wall of the sealing plate 6, and the two annular grooves 61 correspond to the first filter cartridge 32 and the second filter cartridge 33 respectively.

An auxiliary mechanism for driving the support frame 2 to reciprocate is provided inside the base 1. By providing the auxiliary mechanism, the entire support plate 21 can be reciprocated on the base 1 at a small angle, so that the tea leaves inside the screening cylinder 3 can be evenly laid inside for screening. At the same time, when discharging is required, the screening cylinder 3 can be tilted toward the discharge port 62, thereby facilitating discharging.

[0032] Furthermore, the auxiliary mechanism includes a cylinder 13 and a rack 12. A slide groove 14 is provided on the surface of the base 1. The rack 12 is slidably connected to the inside of the slide groove 14. The cylinder 13 is fixedly installed in the inside of the slide groove 14. A driving gear 11 is fixedly installed on the surface of the rotating shaft 10. The rack 12 and the driving gear 11 are meshed. When the auxiliary mechanism is in use, the cylinder 13 is started, and the cylinder 13 drives the rack 12 to slide back and forth in the slide groove 14.

[0033] In summary, during use, tea leaves are poured into the feed tube 4 so that the tea leaves fall into the second filter cylinder 33 in the screening cylinder 3, and then the screening cylinder 3 is driven to rotate by the driving mechanism, so that the first filter cylinder 32 and the second filter cylinder 33 in the screening cylinder 3 rotate synchronously. The mesh size of the second filter cylinder 33 is larger than that of the first filter cylinder 32. Therefore, during the rotation of the tea leaves in the second filter cylinder 33, the smaller tea leaves and the broken residues will fall into the inside of the first filter cylinder 32. The first filter cylinder 32 is also rotating, so the first filter cylinder 32 can leak the broken residues into the outer cylinder 31, so that the smaller tea leaves stay in the first filter cylinder 32. In this way, the tea leaves can be screened into three parts: larger, smaller and broken residues, which is convenient for tea sorting. The leaves are collected in layers, and the blocking plate 6 can be set to intercept the tea leaves in the screening cylinder 3 during the screening process. When the screening is completed, the function of collecting tea leaves of different parts can be realized by opening different blocking blocks 5, which is convenient for operation and use, and this rotation method can protect the tea leaves from being seriously damaged. Compared with the traditional method of directly using the sieve plate and stirring, it will not cause the larger tea leaves to be damaged. The feed pipe 4 is fixed by the support rod 23 and the connecting frame 22, and the feed pipe 4 and the outer cylinder 31 are rotatably connected, so the rotation of the screening cylinder 3 will not affect the feed pipe 4. Similarly, the blocking plate 6 and the connecting frame 22 is fixedly connected, and the blocking plate 6 and the screening cylinder 3 are rotatably connected, so that the blocking plate 6 can be kept stationary, so that the discharge port 62 is always in a fixed position, which is convenient for unloading. The blocking plate 6 can block three different spaces in the screening cylinder 3 to prevent the tea from leaking out during the screening process. When the driving mechanism is in use, the motor 7 is started, the motor 7 drives the active gear 8 to rotate, the active gear 8 drives the gear ring 9 to rotate, and the gear ring 9 drives the screening cylinder 3 to rotate. By setting an auxiliary mechanism, the entire support plate 21 can be reciprocated at a small angle on the base 1, so that the tea inside the screening cylinder 3 can be evenly laid inside for screening. At the same time, when discharging is required, the The screening drum 3 is tilted toward the discharge port 62, so as to facilitate the discharge. When the auxiliary mechanism is in use, the cylinder 13 is started, and the cylinder 13 drives the rack 12 to slide back and forth inside the slide groove 14, and the rack 12 drives the driving gear 11 to rotate back and forth, thereby driving the rotating shaft 10 to rotate back and forth at a small angle, thereby achieving the purpose of reciprocating rotation of the entire support frame 2, and achieving uniform laying of the tea leaves inside the screening drum 3 to achieve the purpose of sufficient screening, reducing the phenomenon of incomplete screening due to accumulation, and when the screening is completed and the material needs to be discharged, the screening drum 3 is tilted downward near the discharge port 62, and then with the rotation of the screening drum 3, the tea leaves in the screening drum 3 can fall out.
