[0029] As shown in Figure 1 , Figure 2 The present embodiment provides a portable rice seedling supplementing device, which comprises a rack 1, a seedling taking and transplanting mechanism and a seedling transporting mechanism installed on the rack, a seedling supporting mechanism arranged in the seedling taking and transplanting mechanism, and a seedling feeding mechanism installed on the seedling transporting mechanism. The seedling taking and transplanting claws of the seedling taking and transplanting mechanism can move up and down and rotate simultaneously, and are used to take the rice seedlings transported to the seedling taking port by the seedling transporting mechanism and transplant the rice seedlings to the rice field. The righting member of the seedling supporting mechanism is arranged in the seedling taking and transplanting claws, can move up and down, and can be adjusted in depth, and is used to right the rice seedlings transplanted to the rice field by the seedling taking and transplanting claws. The seedling transporting mechanism is linked with the seedling taking and transplanting mechanism, and transports the rice seedlings on the seedling tray to the seedling taking port in sequence by rotating the seedling tray. After the seedling taking and transplanting mechanism moves upward, the linkage block on the seedling taking and transplanting mechanism cooperates with the linkage wing on the seedling transporting mechanism to simultaneously complete the seedling transporting in the seedling taking preparation stage. The seedling feeding mechanism is used to press down the seedling tray after the rice seedlings on the bottom layer are taken, so as to realize the seedling feeding.
[0030] In the present embodiment, the rack 1 is a rectangular frame structure with one side open, the seedling transporting mechanism is fixedly installed on the open side of the rack 1, and the seedling taking and transplanting mechanism is fixedly installed on the other side of the rack 1. The rack is provided with a supporting leg 27 at a position opposite to the axis of the seedling transporting mechanism.
[0031] Continuing as shown in Figures 1 to 3 The taking seedling and transplanting mechanism in the embodiment includes a limiting tube 2 fixedly installed on the frame, a moving tube 3 arranged in the limiting tube 2, a fixed tube 4 rotationally connected with the upper end of the moving tube 3, a taking seedling and transplanting claw 5 fixedly connected with the lower end of the moving tube, a right handle 6 arranged at the upper end of the fixed tube, and a linkage block 7 arranged on the fixed tube and used for cooperating with the linkage wing on the seedling transporting mechanism.

The depth of the upper end of the straight groove a at the joint with the arc-shaped groove b is greater than the depth of the arc-shaped groove b. The depth of the lower end of the straight groove a at the joint with the arc-shaped groove b is less than the depth of the arc-shaped groove b. When the fixed tube 4 is driven to move upward by the right handle 6, the limiting pin in the limiting tube 2 is arranged in the straight groove a of the moving tube, and the moving tube 3 moves upward synchronously with the fixed tube 4. When the upward movement reaches a proper stroke (the linkage block drives the linkage wing on the seedling transporting mechanism to reach a proper position of the stroke), the limiting pin in the limiting tube 2 is arranged at the lowermost end of the arc-shaped groove of the moving tube 3. When the fixed tube 4 is driven to move downward by the right handle 6, the moving tube 3 rotates along the arc-shaped groove relative to the fixed tube 5, so that the taking seedling and transplanting claw 5 is rotated to the taking seedling port c of the seedling transporting mechanism, thereby achieving the taking seedling and transplanting rice seedlings to the rice field.

A reset elastic member 12 is arranged between the right handle 8 and the fixed tube 4. When the right handle 8 is pulled upward, the right connecting rod 9 drives the right supporting rod 10 and the right supporting piece 11 to move downward and extend out of the taking seedling and transplanting claw 5, which is used for supporting the rice seedlings transplanted to the rice field through the taking seedling and transplanting claw 5, so as to avoid the taking seedling and transplanting claw 5 from taking out the rice seedlings when the seedlings are moved and supplemented. When the handle is released, the right handle 8 is reset under the action of the reset elastic member 12, the right connecting rod 9 drives the right supporting rod 10 and the right supporting piece 11 to move upward and hide in the taking seedling and transplanting claw 5.
