Two groups of symmetrically arranged rectangular grooves are opened on the surface of the frame 302, and a limiting rod 304 is arranged in the rectangular groove. The limiting rod 304 is fixedly connected to the frame 302, and a sliding block 306 is slidably connected to the surface of the limiting rod 304. The sliding block 306 is fixedly connected to the sealing plate 303, and a locking bolt 307 is threadedly connected to the surface of the sealing plate 303.

[0031] In the present embodiment: when the electric tea picking machine for screening tea leaves is used, the tea leaves are first picked through the U-shaped bucket body 1, and the picked tea leaves are put into the U-shaped bucket body 1 through the feeding mechanism 2. When the tea leaves picked by the U-shaped bucket body 1 are full, the blocking plate 303 is pulled to drive the sliding block 306 to move, and the sliding block 306 slides on the limit rod 304 to release the blocking of the screening net 301, and then the locking bolt 307 is rotated to fix the blocking plate 303 in position, and the screening net 301 is driven to move by shaking the frame 302, so that the tea leaves picked inside the U-shaped bucket body 1 can be preliminarily screened, so that the picked tea leaves do not need to be mixed and put, which reduces the workload of the staff for tea screening in the later stage, thereby reducing the labor intensity of the staff, meeting the actual use needs, and improving the use effect of the device.

[0032] Going further;

[0033] In an optional embodiment, a support plate 313 is fixed to one side of the surface of the U-shaped bucket body 1, and the surface of the support plate 313 is rotatably connected to a rotating disk 309 via a rotating shaft, and a movable column 310 is fixed to the surface of the rotating disk 309. An arc-shaped gear rack 311 is arranged on the outside of the movable column 310, and the arc-shaped gear rack 311 is rotatably connected to the support plate 313 via a rotating rod, and the meshing surface of the arc-shaped gear rack 311 is meshingly connected to a rack rod 312, and two sets of limit sleeves are slidably connected to the surface of the rack rod 312, and the limit sleeves are fixedly connected to the support plate 313, and a servo motor 308 is fixed to the surface of the U-shaped bucket body 1, and the output end of the servo motor 308 drives the rotating disk 309 to rotate via a rotating shaft, and the two ends of the rack rod 312 are fixedly connected to the frame 302 via an L-shaped rod, and the surface of the frame 302 is slidably connected to the U-shaped bucket body 1 via a slide rail.

[0034] In this embodiment: the servo motor 308 is started, thereby driving the rotating disk 309 to rotate, and the rotating disk 309 drives the movable column 310 to rotate, so that the movable column 310 slides in the arc-shaped gear frame 311, and at the same time drives the arc-shaped gear frame 311 to swing back and forth on the support plate 313. Since the arc-shaped gear frame 311 is also meshed and connected with the rack rod 312, as the arc-shaped gear frame 311 moves, the rack rod 312 moves, and the frame 302 moves. The movement of the frame 302 drives the screening net 301 to move back and forth synchronously, which can automatically drive the screening net 301 to move back and forth, thereby reducing the labor intensity of the staff.

[0035] Going further;

[0036] In an optional embodiment, a spring 305 is wound around the surface of the limiting rod 304 , and two ends of the spring 305 are fixedly connected to the sliding block 306 and the frame 302 respectively.

[0037] In this embodiment: the sliding block 306 slides on the limiting rod 304 and compresses the spring 1 305 at the same time. When the blocking plate 303 is released from position locking, the spring 1 305 rebounds, thereby enabling the blocking plate 303 to automatically reset.

[0038] Going further;

[0039] In an optional embodiment, an inclined plate 314 is fixed to the inner side wall of the U-shaped bucket body 1 .

[0041] Going further;

[0042] In an optional embodiment, a screw rod 315 is fixed to one side of the U-shaped bucket body 1 , and a threaded sleeve 316 is threadedly connected to the surface of the screw rod 315 .

[0043] In this embodiment, by rotating the threaded sleeve 316, the threaded sleeve 316 moves on the surface of the screw rod 315, so that the length of the device can be extended, and some areas that cannot be collected can be sampled, thereby improving the flexibility and practicality of the device.

[0044] Further,

[0045] In an optional embodiment, a shielding assembly 4 is installed on the U-shaped bucket body 1, and the shielding assembly 4 includes a shielding plate 401 arranged on the top of the U-shaped bucket body 1, and fixed blocks symmetrically arranged on the upper surface of the U-shaped bucket body 1 and a guide rod 403 fixed on the surface of the fixed block, and a spring 402 is wound around the surface of the guide rod 403, and the two ends of the spring 402 are fixedly connected to the fixed block and the shielding plate 401 respectively;

[0046] A slot 404 matched with the guide rod 403 is formed on the surface of the shielding plate 401 , and the shielding plate 401 and the guide rod 403 are slidably connected via the slot 404 .

[0047] In this embodiment: when the device is continuously picking tea leaves, the shielding plate 401 is regularly pushed, so that the shielding plate 401 slides on the surface of the guide rod 403 through the slot 404, and at the same time, the spring 402 is compressed, so that the shielding plate 401 opens a certain opening to observe whether the collected tea leaves inside the U-shaped bucket body 1 are full. At the same time, through the setting of the shielding plate 401, the picked tea leaves can be shielded to avoid splashing during the feeding process of the feeding mechanism 2, and to avoid the tea leaves from falling due to shaking during the picking process, thereby improving the practicality of the device.

[0048] The working principle and use process of the utility model are as follows: when the electric tea picking machine for screening tea leaves is used, the tea leaves are first picked through the U-shaped bucket body 1, and the picked tea leaves are put into the U-shaped bucket body 1 through the feeding mechanism 2. When the device continuously picks tea leaves, it regularly pushes the shielding plate 401, so that the shielding plate 401 slides on the surface of the guide rod 403 through the slot 404 provided, and at the same time compresses the spring 402, so that the shielding plate 401 opens a certain opening to observe whether the tea leaves collected in the U-shaped bucket body 1 are full. At the same time, through the setting of the shielding plate 401, it can The tea leaves collected can be shielded to avoid splashing during the feeding process of the feeding mechanism 2, and to avoid the tea leaves from falling due to shaking during the collection process, thereby improving the practicability of the device. When the tea leaves collected by the U-shaped bucket body 1 are full, the blocking plate 303 is pulled to drive the sliding block 306 to move, and the sliding block 306 slides on the limiting rod 304, and the spring 1 305 is compressed at the same time, thereby releasing the blocking of the screening net 301, and then the locking bolt 307 is turned to fix the blocking plate 303 in position, and then the servo motor 308 is started to drive the rotary The movable plate 309 rotates, and the movable column 310 is driven to rotate by the rotating plate 309, so that the movable column 310 slides in the arc gear frame 311, and at the same time drives the arc gear frame 311 to swing back and forth on the support plate 313. Since the arc gear frame 311 is also meshed and connected with the rack rod 312, the rack rod 312 is driven to move with the movement of the arc gear frame 311, and the frame 302 is driven to move by the movement of the rack rod 312. The screening net 301 is driven to reciprocate synchronously through the movement of the frame 302, so that the collected liquid inside the U-shaped bucket body 1 can be screened. The tea leaves are preliminarily screened, so there is no need to mix the collected tea leaves, which reduces the workload of the staff for tea screening in the later stage, thereby reducing the labor intensity of the staff, meeting the actual use needs, and improving the use effect of the device. Since the inclined plate 314 is designed with an inclined surface, the tea leaves are better arranged on the screening net 301 along the inclined surface of the inclined plate 314 for screening. By rotating the threaded sleeve 316, the threaded sleeve 316 moves on the surface of the screw 315, so that the length of the device can be extended, and some areas that cannot be collected can be taken, thereby improving the flexibility and practicality of the device.
