Description

Technical Field

[0001] The utility model relates to the technical field of tea spreading, in particular to a tea spreading device. Background Art

[0002] The cultivation and production of tea in my country has a history of thousands of years. Tea is widely welcomed by Chinese and foreign people for its unique aroma. The tea production process is generally divided into the following steps: picking, spreading, killing, rolling, drying, etc. Among them, spreading is one of the most important links. The method of spreading tea is generally to spread the tea leaves evenly on a gauze net or bamboo drying mat, and place them in a cool and ventilated place to dry naturally, so that the fresh tea leaves lose a certain amount of moisture, the leaves wilt, and the green smell disappears, so as to facilitate the subsequent killing process. When spreading fresh tea leaves, it is generally required that the tea leaves should be evenly laid on the gauze net or bamboo drying mat, and the laying thickness should generally not exceed three centimeters.

[0003] However, the current device uses a stirring and tumbling method to spread the tea leaves, which may cause damage or breakage of the tea leaves and the tea leaves are not spread evenly. In addition, the spreading efficiency is low in the natural state.

[0004] An automatic tea-leaf-spreading device disclosed in announcement number CN214126827U, although, the utility model discloses an automatic tea-leaf-spreading device, comprising a "ㄇ"-shaped frame, a circular placing plate is fixed between the longitudinal beams of the frame, a mounting box is arranged in the middle of the bottom surface of the placing plate, a motor is arranged on the bottom surface of the placing plate and in the mounting box, the output shaft of the motor passes through the bottom surface of the mounting box and is coaxially fixed with a rotating shaft, the upper end of the rotating shaft is fixed with a supporting rod perpendicular to it, the supporting rod is connected with a spreading plate perpendicular to the surface of the placing plate, transverse connecting rods perpendicular to it are arranged at both ends of the supporting rod, a rotating rod is rotatably supported between the two connecting rods, a turning claw is fixed on the rotating rod, and a number of turning claws are arranged along the axial direction of the rotating rod, when the turning teeth of the turning claw rotate to the bottom of the rotating rod, the bottom end of the turning claw is lower than the bottom end of the spreading plate, the tea leaves are spread flat on the placing plate, the motor is started, the motor drives the turning claw to rotate, the turning claw contacts with the tea leaves and turns them over, thereby accelerating the speed of spreading them.

[0005] The above patent has achieved the goal of setting a "ㄇ"-shaped frame, fixing a circular placing plate between the longitudinal beams of the frame, setting an installation box in the middle of the bottom surface of the placing plate, and setting a motor on the bottom surface of the placing plate and in the installation box, so that the output shaft of the motor passes through the coaxial fixed shaft on the bottom surface of the installation box, and the upper end of the shaft is connected to a spreading plate vertically set to the surface of the placing plate, and transverse connecting rods perpendicular to the support rod are set at both ends of the support rod, and a rotating rod is supported and supported between the two connecting rods. A flip claw is fixed on the rotating rod to spread the tea leaves flat on the placing plate, and the motor is started. The motor drives the rotating shaft and then drives the support rod to rotate counterclockwise, and the rotating rod rotates with the flip claw. The flip claw contacts the tea leaves and flips them, and the spreading plate flattens the flipped tea leaves for the next flip, so that the tea leaves can be quickly spread; however, the device lacks a screening component and an air-drying mechanism, which can easily cause damage to the tea leaves, and the efficiency of spreading the tea leaves is low.
