Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] like Figure 1-4 As shown, the present invention proposes an anti-clogging tea color sorter, which includes a frame 1 and a collection box 5 placed on the bottom wall of the frame 1. A material rack 6 is fixedly connected to the upper end of the frame 1, and a sorting box 2 of not less than one is installed on the material rack 6.

[0029] The upper end of the frame 1 is provided with a feeder 3 located above the material rack 6;

[0030] A guide component 4 for tea color sorting and discharge is provided on one side of the material rack 6.

[0031] In this invention, the feeder 3 located on the frame 1 can control and adjust the rate at which the tea leaves are fed into the feed rack 6. At the same time, it can perform preliminary screening by vibration when the tea leaves are fed in, so as to improve the screening effect and screening efficiency.

[0032] In an optional embodiment, the feed component 3 includes a support frame 31 fixedly connected to the upper end of the frame 1. A guide frame 33 is slidably connected to the inner side of the support frame 31. A support block 34 extending into the interior of the support frame 31 is fixedly connected to the outer side of the guide frame 33. A spring 313 is fixedly connected between the support block 34 and the support frame 31. A filter screen 311 is fixedly connected to the inner wall of the guide frame 33. A slag guide plate 312 is fixedly connected to the inner wall of the support frame 31. An mounting block 35 is fixedly connected to the upper surface of the guide frame 33. An electric push rod 36 is fixedly mounted on the mounting block 35. A baffle 37 is fixedly connected to the output end of the electric push rod 36. A drive motor 39 is fixedly connected to one side of the support frame 31. A cam 310 is fixedly connected to the output shaft of the drive motor 39. A connecting block 38 penetrating the support frame 31 and located above the cam 310 is fixedly connected to one side of the guide frame 33. A set of slag discharge pipes 32 are connected to one side of the support frame 31.

[0033] In this embodiment, when the tea leaves are fed into the feed rack 6 through the feed inlet between the filter screen 311 and the feed frame 33 and screened by the sorting box 2, the rate of tea leaf feeding is adjusted by starting the electric push rod 36 to adjust the gap between the lower end of the baffle 37 and the filter screen 311. At the same time, when the drive motor 39 starts and drives the feed frame 33 to vibrate through the cam 310, it can shake the tea leaves during the feeding process, thereby reducing the possibility of clogging during the feeding and screening process and improving screening efficiency and screening effect.

[0034] It should be noted that the inner wall of the support frame 31 is provided with a rectangular groove for the support block 34 to slide. The spring 313 is fixedly connected between the lower end of the support block 34 and the rectangular groove. The support block 34 and the spring 313 are supported by the rectangular groove on the inner wall of the support frame 31, so that the guide frame 33 can be elastically supported in the support frame 31.

[0035] The lower end of the baffle 37 is arc-shaped, and a discharge port for discharging is provided between the filter screen 311 and the inner bottom wall of the guide frame 33. The arc-shaped end of the baffle 37 is located at the discharge port. Therefore, the quantity and rate of tea leaf introduction can be adjusted by the gap between the baffle 37 and the filter screen 311.

[0036] In addition, both the filter screen 311 and the slag guide plate 312 are inclined in opposite directions. Tea leaves falling onto the filter screen 311 can be guided towards the discharge port, while broken leaves and impurities falling onto the slag guide plate 312 can be guided along the direction of the slag discharge pipe 32. The discharge ends of the two slag discharge pipes 32 are located on the front and rear sides of the material rack 6, respectively, so that the impurities and broken leaves guided into the slag discharge pipes 32 can be discharged and collected together with the residue after being screened step by step on the material rack 6.

[0037] In an optional embodiment, the guide component 4 includes a guide cylinder 41 fixedly connected to the back of the material rack 6. The inner wall of the guide cylinder 41 is fixedly connected to at least one partition 42. The outer side of the guide cylinder 41 is connected to at least one discharge pipe 44, and the discharge pipes 44 are arranged in a ring-shaped staggered distribution on the guide cylinder 41. The lower end of the guide cylinder 41 is connected to a discharge pipe 43, and a valve 45 is installed on the discharge pipe 44.

[0038] In this embodiment, the guide cylinder 41 located on one side of the material rack 6 can guide the tea leaves after they have been screened by the sorting box 2, and then discharge them through the lower discharge pipe 43 and the side discharge pipe 44. The entire guide component 4 is located on the material rack 6 and inside the frame 1, which can reduce the space occupied by the entire color sorter and improve its practicality.

[0039] It should be noted that the upper end of the discharge pipe 44 is located above the partition plate 42, the guide cylinder 41 is connected to the discharge end of the sorting box 2, the connection is located above the partition plate 42, the valve 45 is located below the partition plate 42, the partition plate 42 is distributed in an inclined manner in the guide cylinder 41, so that the tea material screened by the sorting box 2 is introduced into the guide cylinder 41, and after being blocked and guided by the partition plate 42, it can be discharged through the corresponding discharge pipe 44;

[0040] The number of discharge pipes 44 and partitions 42 are set according to the number of sorting boxes 2.

[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] After the tea leaves are fed into the guide frame 33 by the lifting device, they are guided into the material rack 6 through the discharge port between the filter screen 311 and the guide frame 33. When the tea leaves are screened by the sorting box 2, the activated electric push rod 36 adjusts the gap between the lower arc-shaped part of the baffle 37 and the filter screen 311 by moving the drive baffle 37 closer to or towards the side of the raw material filter screen 311, thereby adjusting the amount and rate of tea leaf introduction. Meanwhile, the activated drive motor 39 repeatedly pushes the connecting block 38 through the cam 310. When the guide frame 33 vibrates, it can shake the tea leaves during the feeding process to reduce the possibility of clogging during the feeding and screening process, thereby improving screening efficiency and screening effect. At the same time, the filter screen 311, which vibrates with the guide frame 33, can perform preliminary screening of the tea leaves. The impurities and broken leaves after preliminary screening can be guided into the slag guide pipe 32 by the slag guide plate 312 and discharged, so that the operator can collect the impurities and broken leaves discharged from the slag guide pipe 32 together when collecting the residue discharged from the material rack 6.

[0044] The guide cylinder 41 located on one side of the material rack 6 can guide the tea leaves after they have been screened by the sorting box 2. The tea leaves are then discharged through the lower discharge pipe 43 and the side discharge pipe 44 and collected through the collection box 5 or a conventional collection bag. The entire guide component 4 is located on the material rack 6 and inside the frame 1, which can reduce the space occupied by the entire color sorter.

[0045] 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.
