Description

Technical Field

[0002] After fresh tea leaves are picked, they generally need to go through production processes such as withering, rolling and drying before they can be sold on the market. Most of the existing tea production processes are carried out in different equipment in the tea production line, and a conveying device is required between different production equipment to transport tea leaves from one equipment to another for the next process. Therefore, it is necessary to design a tea conveying device suitable for different tea production equipment. However, there are still some problems when using existing rotor structure drones:

[0003] For example, a tea conveying device for tea processing with announcement number CN218902553U has the following technical scheme: it comprises a base plate, a conveyor is installed on the upper side of the base plate, a first U-shaped plate is located on the upper side of the conveyor, a second U-shaped plate is installed on one side of the first U-shaped plate, a filter plate is elastically and slidably matched in the second U-shaped plate, sliding blocks are installed on both sides of the filter plate, and a positioning block is installed on the conveyor. The utility model facilitates the classification and collection of tea leaves by driving the push block through the push block, which reduces the floor space occupied by the tea processing device on the one hand, and reduces the power consumption of the device during the classification process on the other hand, and reduces the processing cost of the producer. The setting of the second L-shaped plate reduces the tilting of the filter plate when sliding, making the process of filtering impurities in the tea leaves more convenient, but the existing tea conveying device is prone to tea accumulation during the feeding process, and the filtering effect is not ideal when passing through the filtering process, and the tea leaves are too high to be completely filtered.
