Through the information collection camera 5, the position and size of the yam can be judged, so that the manipulator 3 can accurately dig out the yam. The support seat 322 is rotatably connected to a long arm 323 through a ball bearing near the top end. The side wall of the support seat 322 near the bottom end is bolted with a cylinder one 325, and the other end of the cylinder one 325 is welded to the lower end surface of the long arm 323.

[0024] The working principle provided by the present utility model is as follows: During the operation of the yam digging device, first, according to the preset movement trajectory, the controller controls the first servo motor 24 to drive the crawler by the wheels 23, so that the yam digging device moves to the designated position. When the yam digging device passes through uneven ground, due to inertia, the movement conditions of the vehicle body 1 and the crawler are different. At this time, under the buffering of the shock absorber 212 and the shock spring 213, the shaking degree of the vehicle body 1 can be reduced, thereby weakening the influence of the shaking of the vehicle body 1 on the information collection of the information collection camera 5, and also avoiding the collision of the fruits stored in the yam storage box 4. After the yam digging device moves to the designated position, the image processor distinguishes the maturity degree, size and precise position of the yam. If the yam meets the picking standard, at this time, the second servo motor 31 is started by the controller. The second servo motor 31 drives the manipulator 3 to rotate to a suitable angle, and then the first cylinder 325 extends, so that the long arm 323 rotates downward with the support seat 322 as the central axis. At the same time, the second cylinder 326 is started, so that the short arm 324 rotates downward around the connection point of the long arm 323 and the short arm 324, and the clamping jaw 33 is moved above the yam. Then, the third servo motor 3311 is started. After the third servo motor 3311 rotates the clamping jaw 33 to a suitable angle, the fourth servo motor 3315 is started. The fourth servo motor 3315 drives the worm 3324 to rotate, and the worm 3324 drives a plurality of worm wheels 3325 to rotate. The plurality of worm wheels 3325 respectively drive the first rocker 3327 to rotate, and the first rocker 3327 drives the second rocker 3328 to rotate around the third rocker 3329, so that the grasping clip 3321 digs the yam. After being dug out, under the cooperation of the first cylinder 325, the second cylinder 326 and the second servo motor 31, and according to the maturity degree analyzed by the image processor, the yam is placed in the appropriate area of the yam storage box 4.
