Description

Technical Field

[0001] This utility model relates to the field of tea pulverizing devices, and more particularly to a pulverizing device for detecting tea components. Background Technology

[0002] Detection of tea components can confirm pesticide residues in tea, ensuring food safety. Moreover, tea testing can not only determine information such as tea variety, origin, and harvesting time, but also evaluate aspects such as aroma, taste, and appearance, thereby improving tea quality. At the same time, scientific testing methods can help enterprises optimize production processes, reduce quality problems, and improve market competitiveness.

[0003] During the testing process, the tea leaves are pulverized. The increased surface area of ​​the pulverized tea particles allows for more thorough contact with the extraction solvent, accelerating the dissolution rate and extraction rate of substances such as tea polyphenols and caffeine, thus facilitating the testing process. Therefore, the tea leaves are pulverized using a tea pulverizing device. Most testing items require the pulverized tea leaves to pass through a 40-mesh sieve to ensure sample uniformity and testing accuracy.

[0004] However, most existing tea component testing pulverizing devices are integrated structures, which makes internal cleaning inconvenient. In addition, the pulverized particles are of uneven size, requiring secondary screening, resulting in poor functionality. Utility Model Content

A rotary motor 9 is provided at the rear end of the bottom plate 1. A transmission box 10 is provided at the front end of the front cover plate 3. A feed pipe 11 is provided on the surface of the front cover plate 3 above the transmission box 10. The screening cylinder 5 and the crushing blade 7 are separate structures. During use, the front cover plate 3 can be removed to separate the screening cylinder 5 and the crushing blade 7 for separate cleaning, which is convenient for cleaning and reuse. At the same time, the screening cylinder 5 synchronously screens the crushed material, making the crushed particles more uniform in size and improving practicality.

[0025] Please see Figure 1 , Figure 2 and Figure 3In this embodiment, the surface of the front cover plate 3 is provided with a fitting pad 31. The diameter of the fitting pad 31 is larger than the outer diameter of the screening cylinder 5. The rear end of the screening cylinder 5 extends to the outside of the bottom plate 1, and the rear end of the inner side of the screening cylinder 5 is provided with a toothed groove 51. The screening cylinder 5 and the bottom plate 1 are rotatably connected. A discharge chamber is provided between the screening cylinder 5 and the outer shell 2. The front cover plate 3 and the outer shell 2 are detachable. When in use, the front cover plate 3 is covered on the outer shell 2, and the front end of the screening cylinder 5 and the fitting pad 31 are tightly fitted, so that the inner side of the screening cylinder 5 forms a sealed space, which is convenient for crushing and processing. After use, the front cover plate 3 can be removed to clean the inside, which improves convenience.

[0026] Please see Figure 4 and Figure 5 In this embodiment, the rotary motor 9 and the base plate 1 are fixedly connected by a mounting bracket. The output end of the rotary motor 9 is fixedly connected to a meshing gear 91, which meshes with the tooth groove 51. The front end of the rotary shaft 6 extends into the transmission box 10 and is fixedly installed with a transmission gear 61. The inner side of the transmission box 10 is meshed with the side of the transmission gear 61 and is fitted with a drive gear 62.

The rotary shaft 6 and the front cover plate 3 are rotatably connected. The rotary motor 9 drives the meshing gear 91 to rotate, thereby synchronously driving the sieve cylinder 5 to rotate through the tooth groove 51. This causes the crushed material to be stirred in the sieve cylinder 5, ensuring the crushing effect. At the same time, the drive motor 63 drives the drive gear 62 to rotate, which in turn drives the rotary shaft 6 to rotate. Multiple crushing blades 7 rotate inside the sieve cylinder 5 to crush the tea leaves.

Multiple crushing blades 7 rotate inside the screening cylinder 5 to crush the tea leaves. The crushed tea leaves are screened by the screening cylinder 5, and the rotating motor 9 drives the meshing gear 91 to rotate, thereby synchronously driving the screening cylinder 5 to rotate through the tooth groove 51, so that the crushed material is agitated in the screening cylinder 5, ensuring crushing efficiency. Finally, the screened tea leaves are discharged through the discharge port 8. After crushing, the front cover plate 3 can be removed to separate the screening cylinder 5 and the crushing blades 7 for easy internal cleaning and reuse.

[0029] Through the above steps, the screening cylinder 5 and the crushing blade 7 are separate structures. During use, the front cover plate 3 can be removed to separate the screening cylinder 5 and the crushing blade 7 for separate cleaning, which is convenient for cleaning and easy for reuse. At the same time, the screening cylinder 5 simultaneously screens the crushed material, making the crushed particles more uniform in size and improving practicality. This solves the problem that the internal cleaning of existing tea component detection crushing devices is inconvenient and the crushed particles are uneven in size.
