Description

Technical Field

[0001] This utility model relates to the technical field of tea processing equipment, and in particular to a fresh tea leaf storage machine. Background Technology

[0002] China is the birthplace of tea and the cradle of tea culture. After thousands of years of development, based on processing techniques and tea varieties, a tea system has been formed, represented by the six major tea categories of China. Tea processing, also known as "tea making," is the process of transforming fresh tea leaves into various semi-finished or finished tea products through various processing steps. Among these, the storage of fresh tea leaves (i.e., the preservation and temporary storage of fresh tea leaves) is a crucial step in the tea processing process, primarily serving to: preserve freshness and delay deterioration, regulate production pace, promote quality optimization, and classify and pre-treat the leaves.

[0003] Currently, the common method of storing tea leaves is to spread them out on the ground in large areas after picking, which is both unhygienic and inconvenient for transportation and processing. Some people also store fresh tea leaves in storage boxes / warehouses, but fresh tea leaves stored in traditional storage boxes / warehouses are prone to yellowing and spoilage, which significantly affects the color, aroma and taste of the tea. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing devices and provide a fresh tea leaf storage machine for storing and temporarily storing fresh tea leaves, solving the problem of large-scale tea leaf spreading on the ground, which is both hygienic and convenient for transportation.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] The tea leaf storage machine includes a frame, a hopper, a conveying device, and a ventilation device. The hopper is located at the top of the frame and has an opening at both the top and bottom. The conveying device includes a conveying geared motor fixed to the frame, a conveying drive wheel at the output end of the conveying geared motor, a sprocket drive shaft arranged front and rear on the frame below the hopper, and a chain conveyor belt on the sprocket drive shaft. The conveying drive wheel and the sprocket drive shaft are connected by chain drive. The chain conveyor belt includes a certain number of hinged chain plates and chains on both sides of the chain plates. Several equidistantly distributed air holes are provided on the chain plates. The chain conveyor belt covers most of the lower opening of the hopper, and the uncovered part is the discharge port. Fresh tea leaves enter the hopper from the upper opening and fall onto the chain conveyor belt, accumulating upwards in the hopper. When fresh tea leaves need to be conveyed out, the conveying geared motor drives the conveying drive wheel, the sprocket drive shaft, and the chain conveyor belt to rotate in sequence, and the fresh tea leaves fall from one end of the hopper discharge port to enter the next process.

[0007] The ventilation device includes a fan fixed to one side of the frame and an air duct. The air duct passes through the chain conveyor belt and extends to the other side of the frame, and the air duct has an upward opening structure. The chain conveyor belt covers the upper opening of the air duct. The working air of the fan enters the air duct and blows cool air upward through the air holes, so that the tea leaves can stay fresh and not turn yellow for a longer period of time.

[0008] Preferably, chain support plates are provided on both sides of the frame, arranged vertically to support the chain.

[0009] Preferably, the bottom of both sides of the hopper is provided with inwardly inclined baffles to prevent fresh tea leaves from falling out of the gaps onto the chain conveyor belt.

[0010] Preferably, a ladder is provided on one side of the silo, extending from the ground to the top of the silo, to facilitate workers going up and down.

[0011] Preferably, the chain conveyor belt is provided with a certain number of equally spaced lifting strips to facilitate the transport of fresh tea leaves.

[0012] Preferably, the ventilation devices are multiple and equidistantly distributed along the frame to improve ventilation efficiency.

[0013] Preferably, the dimensions of the air duct gradually decrease along the airflow direction to ensure more uniform airflow from each vent.

[0014] Preferably, the device also includes a feeding mechanism, which comprises a feeding reduction motor fixed to the top of the hopper, a feeding drive wheel at the output end of the feeding reduction motor, and a feeding shaft located at one end of the hopper's outlet. A certain number of feeding rods are distributed on the feeding shaft, and a feeding driven wheel is provided at one end of the shaft. The feeding drive wheel and the feeding driven wheel are connected by a chain drive. When fresh tea leaves need to be conveyed outwards, the feeding reduction motor sequentially drives the feeding drive wheel, the feeding driven wheel, and the feeding shaft to rotate, thereby causing the feeding rods to disperse and evenly distribute the fresh tea leaves, preventing blockage at the outlet and facilitating subsequent processing.

[0015] Preferably, there are multiple feeding shafts, arranged vertically, with the uppermost feeding shaft being closer to the center of the hopper.

[0016] The beneficial effects of this utility model are as follows: 1. The storage machine is used for the storage and temporary storage of fresh tea leaves, which solves the problem of large-scale tea leaf spreading on the ground, making it both hygienic and convenient for transportation;

[0017] 2. To keep tea leaves fresh for a longer period without turning yellow, ensuring the color, aroma, and taste of the tea. Attached Figure Description
