[0026] like Figure 1-5 As shown, the present invention proposes a stratified tea collection screening structure, including a base plate 1 and a screening box 3. The screening box 3 is located above the base plate 1. A flipping mechanism 5 is provided on the top of the base plate 1. A movable plate 2 is connected to the top of the base plate 1 through the flipping mechanism 5. A vibration mechanism 6 is provided on the top of the movable plate 2. The movable plate 2 is connected to the screening box 3 through the vibration mechanism 6. Three sets of screening mechanisms 4 are provided inside the screening box 3. Four sets of discharge mechanisms 7 are provided on the left side of the screening box 3.
[0027] In this invention, the tea leaves can be layered and screened using the screening box 3 and three sets of screening mechanisms 4. During the screening process, the vibration mechanism 6 can cause the screening box 3 and the three sets of screening mechanisms 4 to vibrate, thereby improving the screening efficiency of the screening box 3 and the three sets of screening mechanisms 4. After the screening is completed, the screening box 3 and the three sets of screening mechanisms 4 can be flipped and tilted using the flipping mechanism 5 and the movable plate 2. With the cooperation of the four sets of discharge mechanisms 7, the tea leaves that have been layered and screened by the screening box 3 and the three sets of screening mechanisms 4 can be collected one by one.
[0028] In an optional embodiment, the three sets of screening mechanisms 4 are all located inside the screening box 3 in a uniform manner, and the four sets of discharge mechanisms 7 are all located on the right side of the screening box 3 in a uniform manner. The three sets of discharge mechanisms 7 at the top correspond to the three sets of screening mechanisms 4 respectively, and the bottom discharge mechanism 7 corresponds to the inner bottom wall of the screening box 3.
[0029] It should be noted that the tea leaves can be sorted in layers by the three sets of screening mechanisms 4 and the screening box 3. The three sets of discharge mechanisms 7 at the top can collect the tea leaves remaining on the three sets of screening mechanisms 4 respectively. At the same time, the tea leaves on the bottom wall of the screening box 3 can be collected by the bottom discharge mechanism 7. The three sets of screening mechanisms 4 and the four sets of discharge mechanisms 7 can achieve the purpose of sorting and collecting the tea leaves in layers.
[0030] In an optional embodiment, the screening mechanism 4 includes a screening plate 41, a handle 42, a fixing component 43, and a support component 44. The screening plate 41 is slidably connected to the right side of the screening box 3 and extends into it. The screening plate 41 is adapted to the screening box 3. The handle 42 is located on the right side of the screening plate 41. The fixing component 43 is located on the top of the screening plate 41 and on the right side of the screening box 3. The support component 44 is located on the outer end face of the screening plate 41.
[0031] It should be noted that the tea leaves can be screened through the screening plate 41, and the mesh size of the three screening plates 41 decreases from top to bottom to ensure that the three screening plates 41 can perform layered screening. The screening plates 41 can be quickly installed and disassembled through the handle 42, the fixing component 43 and the support component 44, so as to facilitate the cleaning and replacement of the screening plates 41 and ensure the screening effect of the screening plates 41.
[0032] In an optional embodiment, the fixing component 43 includes a fixing block 431, a connecting block 432, a threaded groove 433, a threaded rod 434, and a knob 435. The fixing block 431 is located on the top of the screening plate 41, the connecting block 432 is located on the right side of the screening box 3, the top of the fixing block 431 contacts the bottom of the connecting block 432, the threaded groove 433 is formed on the top of the fixing block 431, the threaded rod 434 is movably connected to the top of the connecting block 432 and extends into the interior of the threaded groove 433, the threaded rod 434 engages with the threaded groove 433, and the knob 435 is located on the top of the threaded rod 434.
[0033] It should be noted that when the screening plate 41 needs to be disassembled, the knob 435 is turned, which will drive the threaded rod 434 to rotate. The threaded rod 434 will move upward under the thread thrust of the threaded groove 433. When the threaded rod 434 is disengaged from the threaded groove 433, the screening plate 41 can be pulled to the right by the handle 42 to achieve the purpose of disassembling the screening plate 41.
[0034] In addition, when installing the screening plate 41, the support component 44 makes the screening plate 41 slide to the inside of the screening box 3, and the left side of the screening plate 41 contacts the left side wall of the inner cavity of the screening box 3. At this time, the knob 435 is rotated in the opposite direction, and the threaded rod 434 will move upward under the thread thrust of the threaded groove 433. When the threaded rod 434 engages with the threaded groove 433, the fixing block 431 and the connecting block 432 can be fixed, thereby achieving the purpose of fixing the screening plate 41 and ensuring the stability of the screening plate 41 after installation.
[0035] In an optional embodiment, the support assembly 44 includes two support grooves 441 and two support blocks 442. The two support grooves 441 are respectively opened on the front and rear side walls of the inner cavity of the screening box 3. The right side of the two support grooves 441 is connected to the outside. The two support blocks 442 are respectively disposed on the front and back of the screening plate 41. The two support blocks 442 are slidably connected to the inside of the two support grooves 441.
[0036] It should be noted that the screening plate 41 can be supported by the two support grooves 441 and the two support blocks 442 to ensure the stability of the screening plate 41 inside the screening box 3, thereby preventing the screening box 3 from shaking or flipping.
[0037] In an optional embodiment, the flipping mechanism 5 includes a vertical plate 51, two cylinders 52, and two support rods 53. The vertical plate 51 is located at the top of the base plate 1. The movable plate 2 is rotatably connected to the right side of the vertical plate 51 via a pin. Both cylinders 52 are hinged to the right side of the vertical plate 51, and the piston rods of both cylinders 52 are hinged to the bottom of the movable plate 2 via pins. Both support rods 53 are located at the bottom of the movable plate 2, and the bottom of both support rods 53 abuts against the top of the base plate 1.
[0038] It should be noted that after the screening is completed, by activating the two cylinders 52, the piston rods of the two cylinders 52 will drive the movable plate 2 to rotate under the action of the pin shaft. Under the action of the vibration mechanism 6, the movable plate 2 will drive the screening box 3, screening mechanism 4 and discharge mechanism 7 to rotate, so that the screening box 3, screening mechanism 4 and discharge mechanism 7 are tilted, so that the tea leaves remaining on the screening plate 41 will move to the left under the action of gravity.
[0039] In addition, the two support rods 53 can ensure the stability of the movable plate 2 when it is in the horizontal direction, that is, the screening box 3 and the screening mechanism 4 during operation.
[0040] In an optional embodiment, the discharge mechanism 7 includes a discharge pipe 71 and a cover plate 72. The discharge pipe 71 is connected to the left side of the screening box 3, and the cover plate 72 is hinged to the left side of the discharge pipe 71.
[0041] It should be noted that when the screening box 3, screening mechanism 4 and discharge mechanism 7 are tilted, the tea leaves on the top of the screening plate 41 will move to the left under the action of gravity and move into the discharge pipe 71. At this time, the left side of the discharge pipe 71 can be blocked by the cover plate 72 to prevent the tea leaves from falling. When it is necessary to collect the tea leaves, the cover plate 72 can be opened in sequence to collect the tea leaves after stratification.
[0042] In addition, the bottom of the cover plate 72 is connected to the bottom of the discharge pipe 71 by a buckle. When collecting tea leaves, the staff needs to manually open the buckle to open the cover plate 72, so as to prevent the cover plate 72 from separating from the discharge pipe 71 due to its own weight when the discharge pipe 71 is tilted, which would cause the left side of the discharge pipe 71 to open.
[0043] In an optional embodiment, the vibration mechanism 6 includes a vibration motor 61 and a plurality of springs 62. The vibration motor 61 is located on the outer end face of the screening box 3, and the plurality of springs 62 are located on the top of the movable plate 2. The tops of the plurality of springs 62 are connected to the bottom of the screening box 3.
[0044] It should be noted that the screening box 3 can be supported by multiple springs 62. When screening tea leaves, the vibration motor 61 is started, which drives the screening box 3 and the screening plate 41 to vibrate, thereby improving the screening efficiency of the screening plate 41. At the same time, the stability of the screening box 3 can be ensured by multiple springs 62 during vibration.
[0045] In an optional embodiment, the outer end face of the screening box 3 is provided with a controller, and the two cylinders 52 and the vibration motor 61 are electrically connected to the controller, which can control the two cylinders 52 and the vibration motor 61.
[0046] 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.
