Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, and in particular to a fresh leaf washing device. Background Technology

[0002] In the processing industries that use fresh plant leaves as raw materials, such as tea and Chinese medicinal herbs, the surface of fresh leaves is easily covered with impurities such as dust, mud, insect eggs and pesticide residues after picking. If they are not effectively cleaned, they will directly affect the quality of the finished products (such as the taste and aroma of tea and the efficacy of Chinese medicinal herbs), and may even pose food safety risks.

[0003] However, existing methods for cleaning fresh leaves have shortcomings. They rely on manual rubbing and rinsing, which is not only time-consuming and labor-intensive, but also difficult to scale up. In addition, manual operation can easily damage the cell walls of fresh leaves, resulting in problems such as juice loss and browning, which affect subsequent processing. Furthermore, it is inconvenient to clean fresh leaves evenly and comprehensively, and it is easy to miss some areas, thus reducing the cleaning effect. Therefore, we propose a fresh leaf cleaning device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a fresh leaf washing device, which features a rotating spreading plate to flatten the fresh leaves, preventing them from piling up and affecting the overall uniformity of the washing process. At the same time, the spray nozzles that swing back and forth ensure even and comprehensive rinsing of the fresh leaves, further improving the washing effect and preventing areas from being missed and thus reducing the washing efficiency.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a fresh leaf washing device, including a washing box, a feeding hopper for feeding fresh leaves is fixedly connected to the top of the washing box, a filter screen belt is provided inside the washing box, and a flattening mechanism, a uniform rinsing mechanism and a blowing and draining mechanism are arranged sequentially from left to right on the washing box for flattening the fresh leaves. The flattening mechanism, the uniform rinsing mechanism and the blowing and draining mechanism are all located above the filter screen belt. A filter screen is slidably sleeved inside the washing box, and a discharge port is opened on one side of the washing box. A guide plate is fixedly connected inside the discharge port, and the guide plate corresponds to the filter screen belt.

[0006] A further feature of this invention is that the leveling mechanism includes a drive motor fixedly connected to the top of the cleaning tank, a drive shaft fixedly connected to the output shaft of the drive motor, and a leveling plate fixedly connected to the bottom end of the drive shaft.

[0007] By adopting the above technical solution, fresh leaves are injected from the feed hopper onto the filter belt in the washing box. The filter belt transports the fresh leaves to the right. The output shaft of the drive motor drives the rotation of the drive shaft and the spreading plate, which in turn spreads the fresh leaves on the filter belt flat, preventing the fresh leaves from piling up and affecting the uniformity and thoroughness of the rinsing.

[0008] A further feature of this invention is that the uniform rinsing mechanism includes a worm gear fixedly connected to the inner wall of the top of the cleaning tank, a circulation pump fixedly connected to the bottom of the front side of the cleaning tank, multiple water spray pipes rotatably connected to the inner walls of the front and rear sides of the cleaning tank, and a worm fixedly sleeved on the outside of the drive shaft. The worm meshes with the worm gear. A cylinder is fixedly connected to the front side of the worm gear. A movable frame is slidably sleeved on the outer side of the cylinder. A rack is fixedly connected to one side of the movable frame. A gear is fixedly sleeved on the outer side of the water spray pipe. The rack meshes with multiple gears. Multiple nozzles are fixedly connected to the bottom of the water spray pipe. A water outlet pipe is fixedly connected to the top of the circulation pump. A sealing cover is fixedly connected to the top of the water outlet pipe. The sealing cover is connected to the front end of the multiple water spray pipes. The sealing cover is fixedly connected to the front side of the cleaning tank.

[0009] By adopting the above technical solution, the water in the washing tank can be pumped into the outlet pipe, sealing cover and multiple spray pipes by the circulating pump. Finally, high-pressure water is sprayed from multiple nozzles to wash the flattened fresh leaves. During the washing process, the drive shaft drives the rotation of the worm gear, which in turn drives the rotation of the worm wheel and cylinder. The cylinder drives the moving frame and rack to move back and forth. The rack drives multiple gears, spray pipes and nozzles to swing back and forth, thus allowing the leaves to be washed evenly and comprehensively. This makes the washing more uniform, thorough and complete, avoiding areas that are not cleaned and thus reducing the washing effect.

[0010] A further feature of this invention is that a guide groove is provided on the top inner wall of the cleaning tank, and a guide block is slidably fitted in the guide groove, the guide block being fixedly connected to the top of the rack.

[0011] By adopting the above technical solution, the rack can be guided, making its movement more stable and smooth.

[0012] A further feature of this invention is that the air-drying mechanism includes a transition box fixedly connected to the top of the cleaning box, a fan fixedly connected to the top of the transition box, three air-blowing pipes fixedly connected to the bottom of the transition box, multiple air-blowing nozzles fixedly connected to the bottom of the air-blowing pipes, the air-blowing pipes fixedly connected to the front and rear inner walls of the cleaning box, and a common branch pipe fixedly connected between the transition box and the air-blowing pipes.

[0013] By adopting the above technical solution, the washed fresh leaves continue to be conveyed to the right through the filter belt. The water on the fresh leaves can be drained through the filter belt. At the same time, the fan can draw air into the transition box and the blowing pipe, and finally blow it out from multiple blowing nozzles to dry the fresh leaves. Finally, the fresh leaves are discharged from the discharge port for collection and processing.

[0014] A further feature of this invention is that one side of the filter screen extends through one side of the cleaning tank and is fixedly connected to a sealing plate, the sealing plate being movably abutting against one side of the cleaning tank, and a water inlet pipe and a drain pipe being fixedly connected sequentially from top to bottom on one side of the cleaning tank.

[0015] By adopting the above technical solution, it is convenient to disassemble and replace the filter screen, and it is also convenient to change the clean water regularly.

[0016] The beneficial effects of this utility model are:

[0017] 1. This utility model uses a filter belt to transport fresh leaves to the right. The output shaft of the drive motor drives the rotation of the drive shaft and the spreading plate, which flattens the fresh leaves on the filter belt and prevents them from piling up and affecting the uniformity and thoroughness of rinsing.

[0018] 2. This utility model uses a circulating pump to draw water from the washing tank into the outlet pipe, sealing cover, and multiple spray pipes. Finally, high-pressure water is sprayed from multiple nozzles to rinse the flattened fresh leaves. During the rinsing process, the drive shaft drives the rotation of the worm gear, which in turn drives the rotation of the worm wheel and cylinder. The cylinder drives the moving frame and rack to move back and forth, and the rack drives multiple gears, spray pipes, and nozzles to swing back and forth. This swinging motion allows for even and comprehensive rinsing of the fresh leaves, making the rinsing more uniform, thorough, and preventing areas from being missed and reducing the cleaning effect.

[0019] 3. In this utility model, the washed fresh leaves continue to be conveyed to the right via a filter belt. The filter belt can drain the water from the fresh leaves. At the same time, the fan can draw air into the transition box and the blowing pipe, and finally blow it out from multiple blowing nozzles to dry the fresh leaves. Finally, the fresh leaves are discharged from the discharge port for collection and processing. Attached Figure Description
