Description

Technical Field

[0001] The utility model belongs to the technical field of material conveying, and in particular relates to a screw conveyor. Background Art

[0002] With the continuous development of science and technology, and people's increasing attention to health and natural products, the demand for plant extracts is also increasing, and plant leaf extraction technology is also constantly improving. More and more consumers tend to choose medicines and health products of natural origin, which provides a broad market space for the application of plant leaf extracts. The main purpose of extracting drugs from plant leaves is to obtain biologically active compounds, which usually have the potential to treat diseases, improve health or prevent diseases. After scientific research and verification, these plant-derived compounds can be developed into drugs or drug precursors for clinical treatment. The active ingredients in plant extracts can also be used to develop health products to help improve people's health. In addition, the active ingredients in plant extracts are also commonly used in the cosmetics industry, such as skin care products, shampoos, etc. These ingredients can improve skin quality, moisturizing, anti-wrinkle, etc.

[0003] During the plant leaf extraction process, the plant leaves need to be processed in advance, including screening, washing, drying, and crushing. During the processing, in order to reduce the influence of the external environment on the plant leaves, a screw conveyor is usually used for transportation. However, when the traditional screw conveyor is used to transport the plant leaves, since the plant leaves themselves are light and large in size, congestion easily occurs at the feed port of the screw conveyor, which reduces the smoothness of the plant leaf transportation. For this reason, the present application proposes a screw conveyor to solve the above problem. Utility Model Content
