However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0018] Example

[0019] Please refer to the drawings of the specification. In the embodiment of the utility model, a tea air sorting machine that is easy to maintain includes a frame 1; a box body 2 is installed on the frame 1; a driving box 3 is fixedly connected to the left side of the box body 2; a movable slot 6 is vertically opened in front of the driving box 3; a threaded rod 4 is vertically rotatably arranged inside the driving box 3; the top of the threaded rod 4 passes through the driving box 3 and extends to the outside; an air sorting mechanism is threadedly connected to the upper and lower sides of the threaded rod 4 in the driving box 1; the air sorting mechanism includes two oppositely arranged air sorting cylinders 5 and a motor 14 for driving a fan 14 to rotate, and multi-section telescopic rods 9 are fixedly installed in the two air sorting cylinders 5; a T-block 10 is installed at one end of the multi-section telescopic rod 9 away from the air sorting cylinder 5; the upper and lower ends of the motor 14 are A connecting block 12 is provided; a T-slot 13 is provided on the connecting block 12; the T-block 10 is slidably arranged in the T-slot 13; a fan 14 is installed at the output end of the motor 14, and the two air separation cylinders 5 relatively form a hollow cylindrical structure; a 1-2mm gap is provided between the right sides of the two air separation cylinders 5 and the surface of the box body 2, and the upper and lower sides of the threaded rod 4 are respectively provided with left and right threads; the two air separation cylinders 5 are threadedly connected with the left and right threads respectively, and a guide groove 8 is provided directly behind the driving box 3; a guide block 7 is fixedly provided directly behind the two air separation cylinders 5; the guide block 7 is slidably arranged in the guide groove 8, and a spring is provided in the multi-section telescopic rod 9; the multi-section telescopic rod 9 is in a tightened and fixed state after the two air separation cylinders 5 come into contact.

[0020] Usage process:

[0021] When in use, tea leaves enter through the feed port on the top of the frame 1, the air separation component is connected to the box body 2, and the air separation operation is performed in the box body 2 through the air separation mechanism, and finally the tea leaves come out through the multiple discharge ports at the bottom end of the box body 2; when the air separation machine is damaged, in order to facilitate the maintenance of the internal components, the operator can remove the various components from the air separation cylinder 5. When disassembly is required, the threaded rod 4 is manually rotated. Since there is a 1-2mm gap between the air separation cylinder 5 and the box body 2, the air separation cylinder 5 is not fixed to the box body 2, and the threaded rod 4 rotates to drive the two air separation cylinders 5 to move away from each other, so that the two multi-section telescopic rods 9 are stretched, and the motor 1 1 and the fan 14 are leaked out to facilitate the staff to inspect and repair them. When the motor and the fan 14 need to be replaced, push the connecting block 12 to separate the T-slot 13 on the connecting block 12 from the T-block, remove it and replace it. After the repair, rotate the threaded rod 4 to make the two air separation cylinders 5 move relative to each other, so that the two air separation cylinders 5 are in contact, and the internal components are protected; the multi-section telescopic rod is compressed and contracted. When the air separation cylinder 5 forms a cylinder, the multi-section telescopic rod 9 is contracted to the maximum limit and no longer has the contraction condition. Therefore, the motor 11 can be fixed, and the vibration generated when the motor 11 is working will not cause the multi-section telescopic rod 9 to shake.

[0022] In the above process, the air separation cylinder, multi-section telescopic rod, T-block, motor, connecting block, T-slot and driving mechanism cooperate with each other, and the threaded rod is manually rotated to drive the two air separation cylinders away from each other, so that the two multi-section telescopic rods are stretched, and the motor and fan are exposed for convenience of staff to inspect and repair them. This solves the problem that the traditional air separation cylinder needs to be fixed with multiple screws, which is time-consuming and labor-intensive to disassemble during maintenance. When the motor and fan need to be replaced, the connecting block is pushed to separate the T-slot on the connecting block from the T-block, and then it can be replaced after being removed. This device has the advantage of easy maintenance; the present application has a simple structure, strong practicality, and simple operation, which is worthy of promotion.

[0023] The above are only preferred implementations of the utility model. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the utility model. These should also be regarded as the protection scope of the utility model. These will not affect the effect of the implementation of the utility model and the practicality of the patent.
