[0018] In the following, the utility model will be described in detail with reference to the drawings and in combination with embodiments. It should be noted that, without conflict, the embodiments in the utility model and the features in the embodiments can be combined with each other.

[0019] As Figures 1 to 3 shown in the embodiment of the tea leaf picking and collecting device of the utility model, the tea leaf picking and collecting device includes a collecting box 1 and a picking machine 2. The picking machine 2 is telescopically installed on the collecting box 1. A telescopic hose 3 is connected between the picking machine 2 and the collecting box 1. An air extractor 4 is installed on the top of the collecting box 1. An isolation net 5 is installed in the upper part of the collecting box 1. One end of the telescopic hose 3 extends downward from the isolation net 5. One end of the picking machine 2 is provided with a discharge port 6 connected to the telescopic hose 3.

[0020] Specifically, adjust the height of the picking machine 2 according to the picking height, start the air extractor 4 and the picking machine 2. The air extractor 4 creates a negative pressure in the collection box 1, and through the telescopic hose 3, the leaf buds picked by the picking machine 2 are sucked under the isolation net 5 and will not be sucked into the air extractor 4 due to the influence of the isolation net 5.

[0021] In an embodiment of the present application, preferably, an outer wall of the collection box 1 is fixedly connected with a telescopic cylinder 7. A lifting rod 8 is slidably connected in the telescopic cylinder 7. A connection port 9 is provided at a top end of the lifting rod 8. The connection port 9 is rotatably connected to the discharge port 6, and one end of the connection port 9 is fixedly connected with the telescopic hose 3, which is used to adjust the height of the picking machine 2 and make the telescopic hose 3 rise and fall with the lifting rod 8.

[0022] In an embodiment of the present application, preferably, a fastening bolt 10 is provided on the telescopic cylinder 7, and a plurality of card slots 11 adapted to the fastening bolt 10 are linearly arranged on the lifting rod 8, which is used to fix the height of the adjusted lifting rod 8.

[0023] In an embodiment of the present application, preferably, a protective shell 12 is provided on a top of the picking machine 2. One end of the protective shell 12 is fixedly connected with the lifting rod 8, and the other end is rotatably connected with the picking machine 2, which can avoid mechanical injury and serves as a rotating support for the picking machine 2.

[0024] In an embodiment of the present application, preferably, the picking machine 2 includes a core cylinder 21. A plurality of tooth plates 22 are connected to the core cylinder 21. The tooth plates 22 are arranged in a circumferential array on the core cylinder 21 of the picking machine 2. A material swallowing port 23 is provided at a connection position between the tooth plate 22 and the core cylinder 21 of the core cylinder 21. The core cylinder 21 is divided into a plurality of chambers connected to the material swallowing port 23, which is used to prevent the picked bud leaves from flowing out through other material swallowing ports 23.

[0025] In an embodiment of the present application, preferably, a motor 13 is fixedly connected to the protective shell 12. A driving shaft of the motor 13 is fixedly connected with the core cylinder 21, which is used to drive the core cylinder 21 to rotate and make the tooth plates 22 continuously pick the bud leaves.

[0026] In an embodiment of the present application, preferably, the tooth plate 22 intersects the core cylinder 21 tangentially. A Y-shaped cutting edge 24 is provided on the tooth plate 22. The Y-shaped cutting edge 24 belongs to passive shearing and can only cut off the bud leaves, which can reduce the shearing of the tea tree branches by the tooth plate 22 and thus reduce the jamming of the picking machine 2.

[0027] In summary, for the tea leaf picking and collecting device in the above embodiments of the present utility model, specifically, adjust the height of the picking machine 2 by means of the lifting rod 8 in the telescopic cylinder 7 according to the picking height, and snap the fastening bolt 10 into the card slot 11. Start the motor 13 and the air extractor 4. The motor 13 drives the toothed plate 22 of the picking machine 2 to rotate. The Y-shaped cutting edge 24 on the toothed plate 22 snaps into the bud leaves, and the bud leaves are cut off under the action of rotation. The bud leaves enter the material swallowing port 23. Under the action of the air extractor 4, the negative pressure in the collecting box 1 sucks the bud leaves in the core cylinder 21 into the telescopic hose 3 and then into the collecting box 1, and they are isolated in the collecting box 1 by the isolation net 5. This device uses the air extractor 4 to generate negative pressure in the collecting box 1 to suck the bud leaves picked in the picking machine 2 into the collecting box 1. The isolation net 5 isolates the bud leaves in the collecting box 1 to prevent them from entering the air extractor 4, and the bud leaves will not be squeezed and broken in the collecting box 1, thus affecting the tea production quality.
