Description

Technical Field

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

[0002] Tea can be divided into six major tea categories, namely green tea, white tea, black tea, dark tea, oolong tea and yellow tea according to whether it is fermented and the degree of fermentation. The production processes of different teas are somewhat different. However, the spreading process is an essential process in all tea-making processes. Spreading refers to the process of allowing the freshly picked tea leaves to lose water for a period of time, promoting the withering and wilting of the hard and brittle fresh tea stalks, making the leaf texture soft and highly plastic, which is convenient for shaping. In the traditional spreading process, manual flipping of the tea leaves is required. To facilitate the flipping process, rake teeth are usually provided on the spreading device. For example, the utility model with the publication number CN220823909U records a tea spreading device, including a frame, a tea frame and a dust suction component. The tea frame is slidably arranged back and forth in the frame and extends to the front side thereof. The dust suction component is arranged at the top of the frame. It also includes a sliding frame, a rotating frame and a hinged frame. The sliding frame is slidably arranged back and forth in the frame. By means of this device, the back-and-forth movement of the rake teeth can be realized to flip the tea leaves. However, when the rake teeth move, they always move back and forth only on the same straight line, and it is impossible to flip the tea leaves outside the straight path, resulting in a limited flipping range and some tea leaves not being flipped. In view of this, the utility model provides a tea spreading vehicle in the hope of overcoming this technical problem. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a tea spreading vehicle, which can change the lateral position of the scraping rod, so that the tea leaves can be flipped from different straight paths, improving the uniformity of tea leaf flipping and further improving the uniformity of spreading.

[0004] To solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A tea spreading vehicle includes a tea spreading trough. Moving wheels are arranged at the bottom of the tea spreading trough. Left and right troughs are respectively arranged on both sides of the tea spreading trough. A reciprocating lead screw is rotatably arranged in the left trough, and a guide rod is fixedly arranged in the right trough. Sliders are sleeved on both the reciprocating lead screw and the guide rod. One of the sliders is threadedly connected to the reciprocating lead screw. The reciprocating lead screw is connected to the output end of a motor. A plug board is inserted and connected in the slider. A connecting rod is connected between the two plug boards. Fixed scraping rods are arranged at both ends of the connecting rod, and a plurality of rod sleeves are sleeved on the connecting rod. An active scraping rod is connected to the bottom of the rod sleeve. Both the active scraping rod and the fixed scraping rod extend into the tea spreading trough. The plurality of rod sleeves are connected by a synchronous rod. A cylinder is arranged on the connecting rod, and the pushing end of the cylinder is connected to the synchronous rod.

[0006] Further, a push rod is provided on the front side of the tea spreading trough, a rear sealing plate is hingedly connected to the rear side of the tea spreading trough, and a handle is provided on the back of the rear sealing plate.
