[0035] Example

[0036] like Figure 1 and Figure 2 As shown, the utility model proposes a tea uniform distribution multi-stage vibration feeding device, comprising a frame as a bottom support, a holding device 1 installed on the top of the frame for temporarily storing tea, a first vibrator 11 installed at the bottom of the holding device 1, so that the tea contained in the holding device 1 is discharged at a uniform speed. And a lifting and conveying device 3 for conveying tea, a plurality of lifting plates 31 are fixed on the outer surface of the lifting and conveying device 3, and the two ends of the lifting plates 31 are inclined toward the moving direction of the lifting and conveying device 3, so that the lifting and conveying device 3 drives the plurality of lifting plates 31 to move when in operation, and at the same time drives the tea to move upward, and lifts the tea upward in batches.

[0037] Specifically, the feeding device further includes a tea shifting device 2 connected between the holding device 1 and the lifting and conveying device 3. The bottom of the tea shifting device 2 is tilted and equipped with a second vibrator 21, which is convenient for the uniform discharge of tea leaves, so that the number of tea leaves conveyed by each group of lifting plates 31 during movement is roughly the same. The holding device 1 and the tea shifting device 2 are respectively provided with a discharge trough 22 on one side close to the lifting and conveying device 3, and the length of the lifting plate 31 is greater than the width of the discharge trough 22, which is convenient for the discharge of tea leaves.

[0038] For further information, see Figure 4, at the position of the discharge chute 22 on one side of the storage device 1 in the above feeding device, a discharge component 8 for controlling the discharge speed of tea leaves is further provided. The discharge component 8 includes a cross bar 81, a sliding groove 82, an adjusting rod 83, a knob 84, and a positioning plate 85. The cross bar 81 is in contact with the position of the discharge chute 22 of the storage device 1, and the tea leaves are discharged after passing above the cross bar 81, which is convenient for controlling the discharge amount of the tea leaves. Sliding grooves 82 are formed on both sides of the tea leaf shifting device 2, and adjusting rods 83 are threadedly connected to both ends of the cross bar 81, which is convenient for sliding and adjusting the position of the cross bar 81 to adjust the output amount of the tea leaves. One end of the adjusting rod 83 away from the cross bar 81 is fixedly connected with a knob 84, and the knob 84 rotates synchronously with the adjusting rod 83. A positioning plate 85 arranged outside the tea leaf shifting device 2 is also fixedly connected to the adjusting rod 83. When the knob 84 is rotated, the adjusting rod 83 rotates synchronously. At the same time, the adjusting rod 83 is threadedly connected to the cross bar 81 and moves, thereby driving the positioning plate 85 to approach and press the tea leaf shifting device 2, so that the position of the cross bar 81 is fixed.

[0039] An air hood 9 is also installed on the top of the tea leaf shifting device 2. A connecting pipe 91 for connecting an air duct is installed on the top of the air hood 9. The air duct is connected to an exhaust fan to drive air circulation and eliminate the peculiar smell generated after the tea leaves accumulate on the storage device 1.

[0040] Furthermore, as Figure 3 and Figure 4 shown, the above feeding device further includes a guiding mechanism 4. The guiding mechanism 4 is installed on the top of the lifting and conveying device 3 on the side facing away from the storage device 1. The guiding mechanism 4 includes a first guiding hopper 41 fixedly connected to the top of the lifting and conveying device 3. A second guiding hopper 42 is arranged at the lower outlet position of the first guiding hopper 41, which is used to guide the tea leaves conveyed to the upper part so that they are concentrated and fall on the flexible vibrating disk 5. Fixed plates 43 are fixedly connected to both sides of the bottom of the second guiding hopper 42. An installation plate 51 is fixedly connected to the bottoms of the two fixed plates 43 together. The installation plate 51 is fixed on the frame. The flexible vibrating disk 5 is installed on the top of the installation plate 51. A baffle 52 is fixedly connected to the top of the flexible vibrating disk 5, which is used to prevent the tea leaves from scattering and falling. The baffle 52 is arranged in a "U" shape, and the side of the baffle 52 away from the lifting and conveying device 3 is open, which is convenient for the tea leaves to be output to the position of the guiding box 6. The discharge port of the second guiding hopper 42 is arranged above the baffle 52, so that the tea leaves accurately fall on the flexible vibrating disk 5.

[0041] Finally, the flexible vibration plate 5 is located at the bottom of the guide mechanism 4. The flexible vibration plate 5 receives the tea leaves in the guide mechanism 4 and generates vibrations at its bottom. After the tea leaves are evenly distributed, they are transported to the electric conveyor belt 7 through the guide box 6. When the flexible vibration plate 5 is in working condition, periodic vibrations will be generated on its surface. Such vibrations can move and rearrange the tea leaves on the surface. By adjusting the frequency, amplitude and direction of the vibration, the tea leaves can be evenly distributed on the surface of the vibration plate, and the tea leaves can also be moved and discharged. This is a prior art and will not be elaborated on here. Therefore, the tea leaves are not stacked together after being dispersed by vibration. The guide box 6 is tilted between the flexible vibration plate 5 and the electric conveyor belt 7, so that the evenly distributed tea leaves slide onto the electric conveyor belt 7, which is convenient for subsequent color sorting operations.

[0042] In this embodiment, after the tea leaves are piled on the holding device 1, the first vibrator 11 is started, so that the tea leaves are uniformly discharged through the discharge trough 22 of the holding device 1 near the lifting and conveying device 3, and the tea leaves fall into the tea shifting device 2. At the same time, after the second vibrator 21 is started, the tea leaves are driven along the inclined ground of the tea shifting device 2 to approach the lifting and conveying device 3, and are discharged through the discharge trough 22 and caught by the lifting plate 31 installed on the lifting and conveying device 3, and the tea leaves are lifted upward when the lifting and conveying device 3 is running. When the tea leaves move to the top, the lifting plate 31 flips over and pours the tea leaves into the first guide bucket 41, and the tea leaves are guided by the second guide bucket 42 to reach the top of the flexible vibration plate 5. After the flexible vibration plate 5 is started, the tea leaves on its upper surface are evenly distributed, and after adjusting the amplitude frequency, amplitude and direction of the vibration, the tea leaves are discharged to the side of the guide box 6, and the tea leaves are guided by the guide box 6 to the electric conveyor belt 7, and the electric conveyor belt 7 moves to the color sorting position.

[0043] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
