Description

Technical Field

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

[0002] The tea wind sorter is a kind of equipment used in tea processing. Its main function is to use wind power to grade and screen tea leaves, and to separate light impurities, tea dust, yellow leaves, etc. from high-quality tea leaves. Because tea particles of different qualities have different settling speeds under the action of wind, the wind sorter can separate tea leaves from debris and impurities based on this principle.

[0003] Although the existing air classifier can separate tea leaves from debris, it is not ideal for separating light impurities such as dust that easily adhere to the surface of tea leaves. The dust does not fall in the order of tea leaves being air-selected but is randomly mixed with tea leaves and tea debris (refer to the background technology of tea air classifier application No. 201720165119.3), resulting in a decrease in the quality of tea leaves. The purpose of the utility model is to improve the structure of the existing tea air classifier to solve the above technical problems. Utility Model Content

[0004] The purpose of the utility model is to provide a tea air sorting 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 box body, a connecting pipe, a screen frame, a motor and a fan, a feed pipe and a discharge pipe are respectively arranged at both ends of the box body, the axis line connecting the feed pipe and the discharge pipe is inclined, the connecting pipe is located in the box body and respectively forms a rotating pair with the feed pipe and the discharge pipe, the screen frame is located in the box body, the screen frame is flat and the two ends of the screen frame are respectively connected with the connecting pipe, the screen frame is used to place tea leaves, the motor is installed inside the box body and is transmission-connected with the connecting pipe, the fan is fixedly installed on one side of the box body, and an opening corresponding to the fan is formed on the other side of the box body.

[0006] In order to optimize the above technical solution, further measures are taken: the mesh frame is inclined, and the inclined design helps the tea leaves to gradually slide down along the mesh frame under the action of gravity.

[0007] As a further improvement of the above technical solution: a buffer column is arranged in the mesh frame, the buffer column is welded and fixed to the mesh frame, and the axis of the buffer column is perpendicular to the plane where the mesh frame is located. The purpose of setting the buffer column is to hinder the movement of tea leaves in the mesh frame through the buffer column, prolong the residence time of tea leaves in the mesh frame, and ensure that the airflow blown out by the fan can fully act on the tea leaves to ensure that dust, debris and tea leaves are fully separated.

[0008] As a further improvement of the technical solution: a driving gear is arranged on the motor shaft, and a transmission gear is sleeved on the side of a connecting pipe. The driving gear is meshed with the transmission gear to realize the transmission connection between the motor and the connecting pipe. The transmission is realized through the driving gear and the transmission gear, and the power output is stable.

[0009] As an improvement to the above technical solution: the direction of the airflow blown out by the fan is perpendicular to the axis line connecting the feed pipe and the discharge pipe, so as to ensure that the airflow can accurately act on the mesh frame and the tea leaves in the mesh frame.

[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 air sorting machine, which can effectively remove debris carried in the tea leaves and dust and sand adhering to the surface of the tea leaves by turning the tea leaves over and using airflow to drive the tea leaves in a mesh frame during the process. The separation efficiency is high and the tea leaves will not be damaged. BRIEF DESCRIPTION OF THE DRAWINGS

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.

[0018] Example

[0019] See also Figure 1-3The utility model provides a tea air sorting machine, comprising a box body 1, a connecting pipe 2, a mesh frame 3, a motor 4 and a fan 5. A feeding pipe 101 and a discharging pipe 102 are respectively arranged at both ends of the box body 1, and the axis line connecting the feeding pipe 101 and the discharging pipe 102 is inclined.

[0020] The connecting pipe 2 is located in the box body 1 and forms a rotating pair with the feeding pipe 101 and the discharging pipe 102 respectively.

[0021] The mesh frame 3 is inclined and is located in the box body 1. The mesh frame 3 is flat and both ends of the mesh frame 3 are respectively connected to the connecting pipe 2. The mesh frame 3 is used to place tea leaves. A buffer column 301 is arranged in the mesh frame 3. The buffer column 301 is welded and fixed to the mesh frame 3 and the axis of the buffer column 301 is perpendicular to the plane where the mesh frame 3 is located. The buffer column 301 is arranged to extend the residence time of the tea leaves in the mesh frame 3. It should be noted that the gap of the mesh frame 3 should be smaller than the specification of the tea leaves to prevent the tea leaves from falling from the gap of the mesh frame 3.

[0022] The motor 4 is installed inside the box 1 and is transmission-connected to the connecting pipe 2. A driving gear 401 is provided on the rotating shaft of the motor 4. A transmission gear 201 is sleeved on the side of the connecting pipe 2. The driving gear 401 is meshed with the transmission gear 201 to realize the transmission connection between the motor 4 and the connecting pipe 2.

[0023] The fan 5 is fixedly installed on one side of the box body 1 , and an opening corresponding to the fan 5 is formed on the other side of the box body 1 . The direction of the airflow blown out by the fan 5 is perpendicular to the axis line connecting the feed pipe 101 and the discharge pipe 102 .

[0024] The control method of the present invention is to realize automatic control through an external controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will not explain the control method and circuit connection in detail.

[0025] Working principle: Tea leaves are input from the feeding pipe 101. Since the feeding pipe 101, the mesh frame 3 and the discharging pipe 102 are arranged obliquely, the tea leaves will slowly move along the feeding pipe 101, the mesh frame 3 and the discharging pipe 102 under the influence of gravity. During the process, the motor 4 is started. Due to the meshing of the driving gear 401 and the transmission gear 201, the motor 4 will drive the connecting pipe 2 to move, so that the mesh frame 3 connected to the connecting pipe 2 will rotate synchronously. During the rotation, the tea leaves can be turned over in the mesh frame 3, and the tea leaves, dust and gravel can fall through the gap of the mesh frame 3 and be separated from the mesh frame 3. During the execution of the above actions, the fan 5 can be started, and the airflow blown out by the fan 5 can act on the tea leaves through the gap of the mesh frame 3. The airflow and the turning action can effectively separate the debris and dust attached to the surface of the tea leaves from the tea leaves.

[0026] 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.
