[0004] However, for the existing planar vibrating screens, during manual operation, the tea is usually directly placed in a pile on the screen mesh for screening, and when using a conveyor, the tea can only be conveyed to the screen mesh from the same position, and then the screen mesh is used to screen and remove impurities from the tea. Most of the existing screen meshes of planar vibrating screens are inclined. If the tea accumulates in a pile, it will affect the screening and impurity removal effect and the screening and impurity removal efficiency. Summary of the Invention

Detailed implementation manners

[0033] In order to make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0034] The following describes in detail the specific implementation of the present invention with reference to specific embodiments.

[0035] As Figure 1 、 Figure 2 、 Figure 4 、 Figure 7 and Figure 8 shown, an intelligent tea refining and impurity removing device provided by an embodiment of the present invention includes a frame 1, and further includes:

[0036] A leaf feeding module 2, the leaf feeding module 2 includes a leaf spreading cover 21, the leaf spreading cover 21 is installed on the frame 1 through a mounting bracket 11, a leaf inlet 22 is provided at the top of the leaf spreading cover 21, a leaf spreading plate 23 and a guide rod 24 are provided inside the leaf spreading cover 21, the leaf spreading plate 23 is located directly below the leaf inlet 22, and the leaf spreading plate 23 is slidably installed on the guide rod 24 in the vertical direction. A first spring 25 connected to the leaf spreading plate 23 is also sleeved on the guide rod 24;

[0037] An impurity removing module 3, the impurity removing module 3 includes a impurity holding seat 31 installed on the frame 1, a impurity discharging port 311 is opened at the bottom of the impurity holding seat 31, a screening frame 32 is slidably installed on the impurity holding seat 31, a plurality of screening holes 321 are opened on the bottom surface of the screening frame 32, side pressing plates 33 are provided on both sides of the screening frame 32 along its sliding direction, the side pressing plates 33 are in contact with the side walls of the screening frame 32, and the side of the side pressing plate 33 away from the screening frame 32 is connected to the mounting bracket 11 through a plurality of second springs 34;

[0038] A control module 4, the control module 4 is arranged in the leaf spreading cover 21, and the control module 4 is respectively connected to the leaf spreading plate 23 and the screening frame 32. The control module 4 drives the leaf spreading plate 23 to reciprocate in the vertical direction through a cam mechanism, and synchronously drives the screening frame 32 to reciprocate and swing in the horizontal direction.

[0039] In the embodiment of the present invention, during use, only need to start the control module 4, and the control module 4 can drive the leaf scattering plate 23 to move reciprocally in the vertical direction. Just put the tea leaves into the leaf scattering cover 21 from the leaf inlet 22, the tea leaves will first fall on the leaf scattering plate 23, and then scatter onto the screening frame 32 through the leaf scattering plate 23. By adjusting the height of the leaf scattering plate 23, the range where the tea leaves scatter onto the screening frame 32 can be adjusted, so that the tea leaves are evenly scattered onto the screening frame 32. At the same time, the control module 4 will synchronously drive the screening frame 32 to swing reciprocally in the horizontal direction, so as to screen and remove impurities from the tea leaves falling on the screening frame 32.

[0040] As Figure 7 and Figure 8 shown, as a preferred embodiment of the present invention, the control module 4 includes a drive shaft 41 installed in the leaf scattering cover 21 and a drive motor 42 installed on the frame 1. The output end of the drive motor 42 is in transmission connection with the drive shaft 41. A cam 43 is sleeved on the drive shaft 41, and the side surface of the cam 43 always abuts against the bottom surface of the leaf scattering plate 23. A side baffle 44 is provided on each of the left and right sides of the cam 43, and the two side baffles 44 are respectively connected to both sides of the screening frame 32 along its sliding direction through a connecting rod 45.

[0041] In the embodiment of the present invention, the output end of the drive motor 42 is connected to the drive shaft 41 through a belt and pulley mechanism. In addition, the upper surface of the leaf scattering plate 23 is inclined in the direction from the middle to the periphery. During use, only need to start the drive motor 42, and the drive motor 42 can drive the drive shaft 41 to rotate through the belt and pulley mechanism. The drive shaft 41 can drive the cam 43 to rotate synchronously. Through the rotation of the cam 43 and the elastic force of the first spring 25, the leaf scattering plate 23 can always abut against the side wall of the drive motor 42, so that the leaf scattering plate 23 moves up and down reciprocally along the guide rod 24. Since the tea leaves will first fall on the leaf scattering plate 23 after entering the interior of the leaf scattering cover 21 from the leaf inlet 22, and then scatter onto the screening frame 32 through the leaf scattering plate 23. By adjusting the height of the leaf scattering plate 23, the range where the tea leaves scatter onto the screening frame 32 can be adjusted, so that the tea leaves are evenly scattered onto the screening frame 32.

[0042] At the same time, during the rotation of the cam 43, the protruding end of the cam 43 will alternately contact the two side baffles 44 and push them to move in the horizontal direction. The side baffle 44 can drive the screening frame 32 to slide synchronously on the impurity holding seat 31 through the connecting rod 45. At the same time, with the elastic restoring force provided by the second springs 34 on both sides of the screening frame 32, the screening frame 32 can be driven by the cam 43 to swing reciprocally, so that the impurities in the tea leaves fall into the impurity holding seat 31 through the screening holes 321 at the bottom of the screening frame 32, realizing the screening of the tea leaves.

[0043] It should be noted that in this device, when the leaf - spreading plate 23 is at the upper limit position, the range where the tea leaves are scattered is the largest at this time, and the screening frame 32 will be located at the middle position, so that the tea leaves are dispersed to the area near the outer edge of the screening frame 32. When the leaf - spreading plate 23 is at the lower limit position, the range where the tea leaves are scattered is the smallest at this time, and the screening frame 32 is still located at the middle position, thus dispersing the tea leaves to the area near the center of the screening frame 32. During the up - and - down movement of the leaf - spreading plate 23, the tea leaves can be gradually dispersed to each area of the screening frame 32. While screening the tea leaves, the tea leaves can be evenly dispersed, which is convenient for screening and removing impurities.

[0044] As Figure 4 and Figure 9 shown, as a preferred embodiment of the present invention, an avoidance hole 12 is provided on the frame 1, and one side of the impurity - containing seat 31 is hinged in the avoidance hole 12. A flipping module 5 for adjusting the inclination of the impurity - containing seat 31 is further provided at the bottom of the frame 1.

[0045] In the embodiment of the present invention, during use, during the process of screening and removing impurities, the impurity - containing seat 31 is in a horizontal state. When the screening is completed, in order to quickly discharge the screened tea leaves and the sorted impurities from the impurity - containing seat 31 and the screening frame 32, the flipping module 5 can be controlled to work. By controlling the flipping module 5 to adjust the inclination of the impurity - containing seat 31, the impurity - containing seat 31 can drive the screening frame 32 to tilt synchronously, so that the tea leaves and impurities slide to one side, which is convenient for collection.

[0046] Meanwhile, when both the impurity - containing seat 31 and the screening frame 32 are in an inclined state, as long as the side baffle 44 can still contact the cam 43, the screening work can proceed normally. Therefore, after appropriately increasing the area of the side baffle 44, the screening frame 32 can perform the screening and impurity - removing operation in an inclined state, and the flexibility of the device in use is high.

[0047] As Figure 9 and Figure 10 shown, as a preferred embodiment of the present invention, the flipping module 5 includes a mounting plate 52 installed below the frame 1, and a sliding seat 53 slidably installed at the bottom of the impurity - containing seat 31. A third spring 55 is further provided between the sliding seat 53 and the bottom of the impurity - containing seat 31. A hydraulic telescopic rod 51 is hinged on the mounting plate 52, and the telescopic end of the hydraulic telescopic rod 51 is hinged on the sliding seat 53. A plugging plate 54 is also slidably installed at the bottom of the impurity - containing seat 31, and the plugging plate 54 is connected to the sliding seat 53. A limiting plug 56 is provided at one end of the plugging plate 54 away from the sliding seat 53, and a limiting component 6 for limiting the limiting plug 56 is provided at the bottom of the frame 1.

[0048] In an embodiment of the present invention, when the impurity removal module 3 performs screening and impurity removal, the blocking plate 54 will block the impurity discharge port 311 at the bottom of the impurity storage seat 31. When it is necessary to discharge the screened tea leaves and impurities from the impurity removal module 3, only need to control the hydraulic telescopic rod 51 to contract. In the initial state, due to the limitation of the limiting component 6, the hydraulic telescopic rod 51 will drive the blocking plate 54 to slide along the bottom of the impurity storage seat 31 through the sliding seat 53, so as to release the blocking of the impurity discharge port 311. When the limiting plug 56 disengages from the limiting component 6, as the hydraulic telescopic rod 51 continues to contract, the impurity storage seat 31 can be driven to turn downward through the sliding seat 53, and the tea leaves and impurities will slide to the lower side under the action of gravity, so that the impurities will fall from the impurity discharge port 311, and the tea leaves after impurity removal will accumulate in the screening frame 32, which is convenient for taking out the tea leaves.

[0049] As Figure 9 and Figure 10 shown, as a preferred embodiment of the present invention, the limiting component 6 includes two mounting blocks 61 mounted on the bottom of the frame 1, and the two mounting blocks 61 are symmetrically distributed on both sides of the limiting plug 56. A limiting block 62 is slidably mounted at one end of each of the two mounting blocks 61 facing each other, and the limiting block 62 is connected to the inside of the mounting block 61 through a fourth spring 63. An inclined surface 621 is provided at the bottom of one end of each of the two limiting blocks 62 facing each other.

[0050] In an embodiment of the present invention, when the impurity storage seat 31 is in a horizontal state, the limiting plug 56 will be located between the two limiting blocks 62. Due to the limitation of the two limiting blocks 62, the hydraulic telescopic rod 51 cannot drive the impurity storage seat 31 to turn downward. At this time, the contraction of the hydraulic telescopic rod 51 can only drive the blocking plate 54 to slide along the bottom of the impurity storage seat 31 until the limiting plug 56 disengages from between the two limiting blocks 62. At this time, the sliding seat 53 can no longer slide on the bottom of the impurity storage seat 31. When the hydraulic telescopic rod 51 continues to contract, it can drive the impurity storage seat 31 to turn downward, so that the impurities are discharged through the impurity discharge port 311 located at the lower end of the impurity storage seat 31. During the process of the hydraulic telescopic rod 51 extending and the impurity storage seat 31 returning to the horizontal position, the limiting plug 56 will contact the inclined surface 621 on the limiting block 62 and push the limiting block 62 to contract into the mounting block 61 until the impurity storage seat 31 returns to the horizontal and the limiting plug 56 fits against the bottom of the impurity storage seat 31. Then, the limiting block 62 will protrude from the mounting block 61 again under the elastic force of the fourth spring 63 and limit the limiting plug 56 again.

[0051] As Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, as a preferred embodiment of the present invention, a material shifting component 7 is further provided on the miscellaneous material holding base 31. The material shifting component 7 disperses the tea leaves in the screening frame 32 by means of reciprocating swinging, which facilitates the screening of the tea leaves.

[0052] As Figure 2 , Figure 3 , Figure 5 and Figure 6 shown, the material shifting component 7 includes a plurality of rotating shafts 71 arranged side by side in the screening frame 32. The rotating shafts 71 are rotatably installed in the screening frame 32. A driving component for driving each rotating shaft 71 to reciprocate synchronously is further provided on the hinged side of the miscellaneous material holding base 31. A plurality of material shifting rods 72 are equidistantly distributed on the rotating shafts 71.

[0053] In the embodiment of the present invention, the driving component can drive each rotating shaft 71 to reciprocate synchronously, so that the tea leaves are dispersed by the material shifting rods 72 on the rotating shafts 71, which facilitates the efficient screening and impurity removal of the tea leaves.

[0054] As Figure 2 , Figure 3 , Figure 5 and Figure 6 shown, the driving component includes a transmission shaft 73 hinged to one end of the material shifting rod 72 close to the hinged side of the miscellaneous material holding base 31. A transmission gear 74 is installed on the transmission shaft 73. A rack 75 meshing with the transmission gear 74 is further provided on the frame 1.

[0055] In the embodiment of the present invention, during the reciprocating sliding of the screening frame 32, each rotating shaft 71 will move synchronously with the screening frame 32. During this process, the rotating shaft 71 can drive the transmission shaft 73 to reciprocate synchronously. Through the cooperation of the transmission gear 74 and the rack 75, the transmission shaft 73 can be driven to rotate. The transmission shaft 73 can drive the rotating shaft 71 to rotate synchronously, so as to drive the material shifting rods 72 to reciprocate in the screening frame 32 and disperse the tea leaves in the screening frame 32.

[0056] It should be supplemented and explained that each transmission shaft 73 is installed in a bearing, and the bearing is slidably installed on the frame 1 along the sliding direction of the miscellaneous material holding base 31, so as to ensure that the transmission gear 74 and the rack 75 will not be disengaged during the flipping of the miscellaneous material holding base 31.

[0057] Working principle: When in use, just start the driving motor 42. The driving motor 42 can drive the driving shaft 41 to rotate through the pulley belt mechanism. The driving shaft 41 can drive the cam 43 to rotate synchronously. Through the rotation of the cam 43 and the elastic force of the first spring 25, the leaf spreading plate 23 can always abut against the side wall of the driving motor 42, so that the leaf spreading plate 23 reciprocates up and down along the guide rod 24. Just put the tea leaves into the leaf spreading cover 21 from the leaf inlet 22. Since the tea leaves will first fall onto the leaf spreading plate 23 after entering the interior of the leaf spreading cover 21 from the leaf inlet 22, and then fall onto the screening frame 32 through the leaf spreading plate 23. By adjusting the height of the leaf spreading plate 23, the range where the tea leaves fall onto the screening frame 32 can be adjusted, so that the tea leaves are evenly scattered onto the screening frame 32. At the same time, during the rotation of the cam 43, the protruding end of the cam 43 will alternately contact the two side baffles 44 and push them to move horizontally. The side baffle 44 can drive the screening frame 32 to slide synchronously on the impurity holding seat 31 through the connecting rod 45. At the same time, with the elastic restoring force provided by the second springs 34 on both sides of the screening frame 32, the screening frame 32 can be driven to swing reciprocally by the cam 43, so that the impurities in the tea leaves fall into the impurity holding seat 31 through the screening holes 321 at the bottom of the screening frame 32, realizing the screening of the tea leaves. At the same time, during the reciprocating sliding of the screening frame 32, each rotating shaft 71 will move synchronously with the screening frame 32. During this process, the rotating shaft 71 can drive the transmission shaft 73 to swing reciprocally synchronously. Through the cooperation of the transmission gear 74 and the rack 75, the transmission shaft 73 can be driven to rotate. The transmission shaft 73 can drive the rotating shaft 71 to rotate synchronously, so as to drive the material pushing rod 72 to swing reciprocally in the screening frame 32, scattering the tea leaves in the screening frame 32, which is convenient for efficiently screening and removing impurities from the tea leaves.

[0058] When the screening is completed, just control the hydraulic telescopic rod 51 to contract. In the initial state, due to the limiting effect of the two limiting blocks 62, the hydraulic telescopic rod 51 will drive the plugging plate 54 to slide along the bottom of the impurity holding seat 31 through the sliding seat 53, so as to release the plugging of the impurity discharge port 311. Until the limit insertion plate 56 disengages from between the two limiting blocks 62. At this time, the sliding seat 53 can no longer slide on the bottom of the impurity holding seat 31. The continuous contraction of the hydraulic telescopic rod 51 can drive the impurity holding seat 31 to turn downward, and the tea leaves and impurities will slide to the lower side under the action of gravity, so that the impurities fall from the impurity discharge port 311, and the tea leaves after impurity removal are accumulated in the screening frame 32, which is convenient for taking out the tea leaves.

[0059] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
