DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts fall within the scope of protection of the present utility model.

[0028] Embodiment 1

[0029] A preferred embodiment of the fresh tea leaf grader provided by the present utility model is as Figures 1 to 5Shown: A fresh tea leaf grader, comprising a base 1 and a partition plate 11. A side plate 2 is fixedly connected to the top of the base 1. A sliding rod 3 is slidably connected inside the side plate 2. The tail of the sliding rod 3 is fixedly connected to an assembly plate 4. A first sieve plate 5 is fixedly connected to one side of the assembly plate 4. A second sieve plate 6 fixedly connected to the assembly plate 4 is arranged below the first sieve plate 5. A third sieve plate 7 fixedly connected to the assembly plate 4 is arranged below the second sieve plate 6. One end of the sliding rod 3 is fixedly connected to a transmission plate 8. A motor 9 fixedly connected to the base 1 is arranged on one side of the transmission plate 8. The output end of the motor 9 is fixedly connected to a push plate 10. A baffle 13 is slidably connected to the top of the base 1. A first spring 12 fixedly connected to the base 1 is fixedly connected to one side of the baffle 13. A protective plate 14 slidably connected to the base 1 is attached to the surface of the baffle 13. A second spring 19 fixedly connected to the side plate 2 and the assembly plate 4 is arranged on the side of the sliding rod 3.

[0030] In this embodiment, through holes reduced by 0.5 times are respectively arranged on the surfaces of the first sieve plate 5, the second sieve plate 6 and the third sieve plate 7. Since the through holes on the first sieve plate 5, the second sieve plate 6 and the third sieve plate 7 are of reduced design, the tea leaves can be sieved step by step.

[0031] In this embodiment, the tail of the push plate 10 is of an arc design. The transmission plate 8 is located on the rotation track of the push plate 10. When the motor 9 is turned on to start the rotation of the push plate 10, the transmission plate 8 will be pushed when the push plate 10 rotates, so that the transmission plate 8 pushes the assembly plate 4 through the sliding rod 3.

[0032] In this embodiment, the sliding rod 3 is perpendicularly arranged with the assembly plate 4. The assembly plate 4 forms a left - right shaking structure with the first spring 12 through the push plate 10. When the push plate 10 disengages from the contact with the transmission plate 8, the transmission plate 8 will rebound under the action of the second spring 19. In the cyclic rotation of the push plate 10, the purpose of controlling the sieving of the first sieve plate 5, the second sieve plate 6 and the third sieve plate 7 is achieved.

[0033] In this embodiment, the partition plate 11 is equally divided into three groups. The tops of the three groups of partition plates 11 are respectively flush with the first sieve plate 5, the second sieve plate 6 and the third sieve plate 7. The partition plate 11 divided into three groups can respectively receive different types of tea leaves for classification.

[0034] In this embodiment, the top of the assembly plate 4 is located on the movement track of the protective plate 14. The assembly plate 4 shields the top of the first sieve plate 5. By controlling the two groups of protective plates 14 to slide to the fitting state with each other, the top of the first sieve plate 5 is shielded in this way, achieving the effect of preventing dust.

[0035] Embodiment 2

[0036] On the basis of Embodiment 1, a preferred embodiment of the fresh tea leaf grader provided by the present utility model is as Figures 1 to 5As shown in the figure: A chute 15 is provided inside the side plate 2, and an engagement groove 16 communicating with the chute 15 is provided on the inner side wall of the side plate 2. A handle 17 is slidably connected inside the chute 15, and a cleaning brush 18 that fits against the first sieve plate 5, the second sieve plate 6, and the third sieve plate 7 is fixedly connected to the surface of the handle 17.

[0037] In this embodiment, the inclination of the engagement groove 16 is the same as that of the first sieve plate 5, the second sieve plate 6, and the third sieve plate 7, so that when the cleaning brush 18 moves, it can clean the first sieve plate 5, the second sieve plate 6, and the third sieve plate 7 along the engagement groove 16.

[0038] In this embodiment, the handle 17 fits tightly against the inner wall of the chute 15. By controlling the handle 17 to slide inside the chute 15, when the handle 17 slides, it will drive the cleaning brush 18 fixedly connected to itself to slide inside the engagement groove 16.

[0039] In this embodiment, the cleaning brush 18 and the handle 17 form an "L" - shaped structure. The handle 17 drives the cleaning brush 18 to form a sliding structure inside the engagement groove 16. Through the sliding of the cleaning brush 18, the tea leaf impurities remaining on the surfaces of the first sieve plate 5, the second sieve plate 6, and the third sieve plate 7 can be cleaned, and there is no need to clean them with a brush anymore.

[0040] The working principle and usage process of the present utility model: First, when it is necessary to grade tea leaves, the fresh tea leaves can be sprinkled on the first sieve plate 5, and then the motor 9 is turned on to start the rotation of the push plate 10. When the push plate 10 rotates, it will push the transmission plate 8, so that the transmission plate 8 pushes the assembly plate 4 through the slide rod 3, thereby controlling the movement of the first sieve plate 5, the second sieve plate 6, and the third sieve plate 7. When the push plate 10 disengages from the transmission plate 8, the transmission plate 8 will rebound under the action of the second spring 19. In the cyclic rotation of the push plate 10, the purpose of controlling the sieving of the first sieve plate 5, the second sieve plate 6, and the third sieve plate 7 is achieved. Since the through - holes on the first sieve plate 5, the second sieve plate 6, and the third sieve plate 7 are designed to be shrinking, the tea leaves can be sieved step by step and finally sieved into the inside of the partition plate 11. When the device is not in use, in order to achieve the purpose of dust - proofing the first sieve plate 5, the second sieve plate 6, and the third sieve plate 7, the baffle 13 can be pushed so that it no longer blocks the protective plate 14, and then the two protective plates 14 can be controlled to slide towards each other until they are in a fitting state, so as to cover the top of the first sieve plate 5. When the baffle 13 is in the initial position, it can limit the protective plate 14 to prevent the protective plate 14 from shifting during the operation of the device.

[0041] After the tea leaves are sorted, impurities of the tea leaves may remain on the surfaces of the first sieve plate 5, the second sieve plate 6, and the third sieve plate 7. At this time, the control handle 17 slides along the inside of the chute 15. When the handle 17 slides, it drives the cleaning brush 18 fixedly connected to itself to slide along the inside of the connecting groove 16. By the sliding of the cleaning brush 18, the tea leaf impurities remaining on the surfaces of the first sieve plate 5, the second sieve plate 6, and the third sieve plate 7 can be cleaned, and there is no need to clean them with a brush anymore.

[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
