Description

Technical Field

[0001] The utility model relates to the field of tea processing equipment, in particular to a tea cleaning machine. Background Art

[0002] Tea washing is an important preparatory step before tea processing. Its main purpose is to remove dust, pesticides and other attachments attached to the surface of the tea leaves during the growth and storage process, ensuring that the tea meets food safety and hygiene standards.

[0003] The existing tea washing process relies on manual stirring or equipment stirring to separate the attachments from the tea leaves. Strong stirring can easily damage the tea leaves and cause the nutrients in the tea leaves to precipitate, which will affect the quality of the tea leaves (a tea washing machine with application number 202322314732.5 and a tea washing box with application number 202320977869.6 also put forward the same point of view in the background technology). The purpose of the present utility model is to propose a tea washing device that is not easy to damage the tea leaves to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of the utility model is to provide a tea cleaning machine to solve the problems mentioned in the background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: including a water tank, a conveyor belt, a vibration plate, an ultrasonic vibration device and a nozzle, a feeding port is formed at the left end of the water tank, the conveyor belt is rotatably installed on the top of the water tank, the conveyor belt is in contact with the water surface of the water tank and blades are arranged on the side of the conveyor belt, the vibration plate is located in the water tank and the two ends of the vibration plate are connected to the water tank through springs, the ultrasonic vibration device is installed on the side of the water tank and the transducer of the ultrasonic vibration device is connected to the bottom surface of the vibration plate, the nozzles are distributed in a matrix shape at the bottom of the water tank and are located below the vibration plate, and the nozzles are connected to the air pump located outside the water tank.

[0006] To optimize the above technical solution, further measures are taken: the ends of each blade are extended and connected to make the ends of the blade closed, so as to prevent the tea leaves from leaving the ends of the blade and separating from the conveyor belt during the tea cleaning process.

[0007] As a further improvement to the above technical solution: a fan is embedded in the feeding port, and the airflow generated by the fan helps to press the tea leaves under the water surface of the sink, so that the blades can drive the tea leaves to move under the water surface of the sink for cleaning.

[0008] As a further improvement of the technical solution: regularly distributed through holes are formed on the vibration plate for bubbles to pass through. The purpose of setting it is to divide the bubbles sprayed from the nozzle through the through holes, so that the bubbles are broken into small pieces so that the bubbles can contact the tea leaves more evenly and dispersedly, which helps to improve the cleaning effect of the tea leaves.

[0009] As an improvement to the above technical solution: the bottom end of the feeding port is located below the conveyor belt, ensuring that the tea leaves fed from the feeding port can be driven by the leaves to move under the water surface for cleaning.

[0010] From the above description of the structure of the utility model, it can be seen that compared with the prior art, the utility model has the following advantages:

[0011] The utility model provides a tea cleaning machine, which conveys tea leaves under water by means of a conveyor belt with blades. During the process, water flow mixed with bubbles will drive attachments to separate from the tea leaves under ultrasonic vibration. The tea leaves can be cleaned without strong stirring, and the washing process is gentle and will not damage the tea leaves. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Example

[0018] See also Figure 1-2 The utility model provides a tea cleaning machine, including a water tank 1, a conveyor belt 2, a vibration plate 3, an ultrasonic vibration device 4 and a nozzle 5. A feeding port 101 is formed at the left end of the water tank 1, a fan 102 is embedded in the feeding port 101, and the bottom end of the feeding port 101 is located below the conveyor belt 2.

[0019] The conveyor belt 2 is rotatably mounted on the top of the water tank 1 , the conveyor belt 2 contacts the water surface of the water tank 1 and blades 201 are arranged on the side of the conveyor belt 2 , and the ends of the blades 201 are extended and connected so that the ends of the blades 201 are closed.

[0020] The vibration plate 3 is located in the water tank 1 and both ends of the vibration plate 3 are connected to the water tank 1 through springs 301 . Regularly distributed through holes for air bubbles to pass through are formed on the vibration plate 3 .

[0021] The ultrasonic vibration device 4 is installed on the side of the water tank 1 and the transducer of the ultrasonic vibration device 4 is connected to the bottom surface of the vibration plate 3. The ultrasonic vibration device 4 is used to drive the vibration plate 3 to generate ultrasonic vibrations. The ultrasonic vibration device 4 belongs to the prior art content and is known to technical personnel in this field. Therefore, the specific structure and working principle of the ultrasonic vibration device 4 will not be further explained.

[0022] The nozzles 5 are distributed in a matrix at the bottom of the water tank 1 below the vibration plate 3. The nozzles 5 are connected to an air pump 501 outside the water tank 1. The air pump 501 pumps gas into the nozzles 5 so that the nozzles 5 generate bubbles to act on the tea leaves.

[0023] Working principle: tea leaves are fed from the feeding port 101 and enter the water surface under the action of the fan 102, and then the moving blades 201 on the tea conveyor belt 2 bring the tea leaves under the water surface. During the process, the air pump 501 and the ultrasonic vibration device 4 continue to operate, and the gas pumped by the air pump 501 leaves from the nozzle 5 to form a large number of bubbles in the water tank 1. The ultrasonic vibration device 4 drives the vibration plate 3 to generate ultrasonic vibrations that continuously act on the water in the water tank 1. The bubbles will be shattered into small bubbles when they come into contact with the vibration plate 3. The ultrasonic oscillation of water mixed with bubbles can effectively separate the attachments on the surface of the tea leaves from the tea leaves, thereby achieving a cleaning effect. During the process, the tea leaves will be driven by the blades 201 of the conveyor belt 2, and finally move to the other end of the water tank 1 for collection by the operator.

[0024] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
