Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, and in particular to a tea leaf fixing conveying device. Background Technology

[0002] Fixing (or killing the green) is a crucial step in tea processing. Its core purpose is to use high temperatures to destroy and deactivate the oxidase activity in fresh leaves, inhibiting the enzymatic oxidation of substances such as tea polyphenols. Simultaneously, it removes the grassy odor and develops the tea aroma, laying the foundation for subsequent quality processes. The quality of the fixation directly determines the color, aroma, and taste stability of the tea. Currently, continuous fixation equipment is widely used in the industry, requiring a conveyor system at the front end to evenly feed the fresh leaves into the fixation chamber.

[0003] Existing conveying devices mostly use fixed-opening hoppers paired with conveyor belts for feeding. However, this has revealed many technical defects in practical applications. For example, the hoppers lack a material control mechanism at the bottom opening, causing tea leaves to continuously and accumulatingly fall onto the conveyor belt. This results in too much tea entering the withering equipment at once, hindering internal heat transfer during withering and leading to incomplete withering, which seriously affects the quality of the finished tea. Secondly, the surface of the conveyor belt is prone to having some broken tea leaves adhering to it due to fresh leaf juice. Over time, this will form a layer of dirt, contaminating subsequent tea production. It may even deteriorate due to long-term accumulation, producing odors and polluting the entire processing environment. Utility Model Content

[0032] Those skilled in the art should connect all electrical components in this case to their compatible external power supply via wires, and should select a suitable controller according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0033] Working Principle: During operation, the conveyor belt 1 is started to transport the tea leaves to be processed. The tea leaves to be processed are then poured into the hopper 9. The motor 11 is then started, driving the drive shaft 12 to rotate the disc block 13. This causes the fixed column 14 on the disc block 13 to rotate around the drive shaft 12. Subsequently, under the hinge action of the fixed column 14, the long plate 15, and the connecting column 16, the baffle frame 17 moves back and forth along the slide rod 19 inside the slide groove 18. This causes the baffle frame 17 to intermittently overlap with the lower discharge port of the hopper 9. That is, when the baffle frame 17 is away from the discharge port, the tea leaves inside the hopper 9 will fall onto the conveyor belt 1 through the discharge port for transport. When the baffle frame 17 overlaps with the discharge port, it will block the discharge port and prevent the tea leaves from falling again. This process is repeated to allow the tea leaves inside the hopper 9 to be processed intermittently. The tea leaves are intermittently conveyed onto the conveyor belt 1 to ensure that they fall into the subsequent fixing equipment intermittently and evenly, thereby effectively ensuring the fixing effect of the tea leaves. During the rotation of the drive shaft 12, the meshing action of the second conical tooth 23 and the first conical tooth 21 will synchronously drive the soft dispersing blade 22 on the transmission shaft 20 to rotate, thereby agitating the tea leaves at the bottom of the hopper 9 to ensure that the tea leaves fall stably from the discharge port, thereby ensuring the stability of the tea leaf conveying. During the conveying process of the conveyor belt 1, the scraper 7 slides through the guide rod 4 inside the limiting groove 3 via the connecting plate 6, and under the action of the spring 5, it always maintains contact with the conveyor belt 1. Therefore, when the tea leaves adhering to the conveyor belt 1 pass by the scraper 7, they will be scraped off by the scraper 7, thereby ensuring the cleanliness of the surface of the conveyor belt 1.
