[0026] like Figure 1-3 As shown, the present invention proposes a drying device for tea processing, including a processing chamber 1 and a feeding port 2 opened at the upper end of the processing chamber 1. A collection box 3 is slidably connected to the inner bottom wall of the processing chamber 1, and a hot air blower 4 is fixedly installed on one side of the processing chamber 1.

[0027] Processing chamber 1 is equipped with a tea drying processing unit 5.

[0028] In this invention, the processing unit 5 inside the processing chamber 1 can dry the vibration-guided tea leaves while also filtering out impurities.

[0029] It should be noted that the front of the processing chamber 1 has an opening for the collection box 3 to be pulled out and slid, so that the operator can easily pull out the collection box 3 to empty the filtered leaf fragments and dust.

[0030] In an optional embodiment, the processing component 5 includes a guide frame 51 slidably connected to the inner wall of the processing chamber 1. A connecting cover 53 is fixedly connected between the upper end of the guide frame 51 and the inner top wall of the processing chamber 1. A plurality of guide plates 52 are fixedly connected to the inner wall of the guide frame 51, and the guide plates 52 are symmetrically distributed in an inclined, staggered manner. A baffle 55 is hinged to the inner wall of the lower end of the guide frame 51. An electric telescopic rod 54 is hinged to one side of the lower end of the guide frame 51, and the output end of the electric telescopic rod 54 is connected to… The baffle 55 is hinged, and the inner wall of the guide frame 51 is fixedly connected to a filter screen 56 located below the baffle 55. A discharge frame 58 with one end penetrating through the processing chamber 1 is fixedly connected to one side of the lower end of the guide frame 51. Two sets of support blocks 59 are fixedly connected inside the processing chamber 1. A set of guide blocks 513 are fixedly connected to both the left and right sides of the guide frame 51. A guide rod 512 with one end penetrating through the guide block 513 is fixedly connected to the support block 59. A spring 510 is fixedly connected between the guide block 513 and the support block 59.

[0031] In this embodiment, the tea leaves fed into the guide rack 51 can be vibrated and dried by the vibrating guide rack 51 and several guide plates 52 inside the guide rack 51. After drying, the tea leaves are conveyed to the filter screen 56. After being vibrated and filtered by the filter screen 56, broken leaves and dust attached to the tea leaves during the drying process can be filtered out. The dried and filtered tea leaves can be collected by being discharged through the discharge rack 58, thereby improving the processing efficiency and quality of the tea leaves.

[0032] It should be noted that the processing chamber 1 is equipped with a drive unit for driving the guide frame 51 to vibrate. The drive unit drives the guide frame 51 to vibrate back and forth along the vertical and horizontal plane.

[0033] The air outlet of the hot air blower 4 is connected to a ventilation pipe 6 that extends through and into the inside of the guide frame 51. The ventilation pipe 6 is a flexible hose, which allows the ventilation pipe 6 extending into the inside of the guide frame 51 to expand and contract with the vibration of the guide frame 51. A guide plate 57 is fixedly connected to the inner wall of the lower end of the guide frame 51, and the guide plate 57 is located below the filter screen 56.

[0034] The guide plate 52 has several ventilation holes, which allow hot air to pass through the ventilation holes while the guide plate 52 guides the tea leaves, so as to dry the tea leaves evenly during the guiding process. The connecting cover 53 is a conical rubber cover, and the upper end of the connecting cover 53 is connected to the feeding port 2, so that the connecting cover 53 can flexibly connect the feeding port 2 and the upper end of the guide frame 51, and can expand and contract with the vibration of the guide frame 51.

[0035] In addition, both the filter screen 56 and the air guide plate 57 are inclined, and the end of the filter screen 56 near the baffle 55 is the lower end, so that the tea leaves on the filter screen 56 can be guided to the baffle 55 along the inclined filter screen 56. The air guide plate 57 is inclined in the opposite direction to the filter screen 56, and the inclined air guide plate 57 can guide the air blown by the ventilation pipe 6 into the guide rack 51.

[0036] Secondly, the lower end of the guide frame 51 is conical, and the baffle 55 and the discharge frame 58 are located on one side of the conical end of the guide frame 51. The end of the discharge frame 58 near the baffle 55 is U-shaped. The inner wall of the lower end of the guide frame 51 is provided with a discharge hole for the baffle 55 to be hinged. After the baffle 55 located in the discharge frame 58 is pulled open by the electric telescopic rod 54, the dried and filtered tea leaves can be discharged from the guide frame 51 along the inclined filter screen 56.

[0037] A rectangular hole is provided on one side of the processing chamber 1 for the material discharge rack 58 to move, so that the end of the material discharge rack 58 passing through the processing chamber 1 has space to move when it vibrates with the guide rack 51.

[0038] In an optional embodiment, the driving component includes a drive motor 511 fixedly mounted on one side of the processing chamber 1. The output shaft of the drive motor 511 is fixedly connected to a rotating shaft 515 with one end passing through the connecting cover 53. A set of cams 514 is fixedly connected to the rotating shaft 515. Abutments 516 located below the cams 514 are fixedly connected to both the left and right sides of the guide frame 51.

[0039] In this embodiment, after the start-up drive motor 511 drives a set of cams 514 on the rotating shaft 515 to rotate, it can drive the guide frame 51 to vibrate by repeatedly squeezing the abutment block 516.

[0040] It should be noted that the connecting cover 53 has a circular hole for the rotating shaft 515 to pass through, and the abutment 516 is located between each group of guide blocks 513. After the guide frame 51 is stably supported and guided by the vertically distributed support blocks 59, guide rods 512 and guide blocks 513, the abutment 516 under pressure can drive the guide frame 51 to reciprocate along the vertical and horizontal plane on the guide rods 512 through the guide blocks 513.

[0041] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. Since this utility model is mainly used to protect mechanical structures, the control method and circuit connection and other technical means will not be described in detail here.

[0042] The working principle in the above embodiments is as follows:

[0043] The tea leaves to be dried are fed into the guide rack 51 through the feeding port 2. After the tea leaves fall onto the top guide plate 52, the drive motor 511 and the hot air blower 4 can be started. The hot air blower 4 continuously blows hot air into the guide rack 51 through the ventilation pipe 6. The drive motor 511 drives the cam 514 to rotate through the drive shaft 515, which repeatedly squeezes and abuts the block 516, causing the guide rack 51 to vibrate repeatedly on the guide rod 512 through the guide block 513. This allows the tea leaves to be guided and fall into the guide rack 51 by several guide plates 52, and dried evenly by the hot air. After the tea leaves have been dried and fallen onto the filter screen 56, the vibrating filter screen 56 filters out broken leaves and dust impurities. Then, the electric telescopic rod 54 is started to pull the baffle 55 to rotate, and the dried and filtered tea leaves are discharged. The filtered broken leaves, impurities and dust fall into the collection box 3 for collection.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
