A receiving box (50) is fixedly installed at the bottom of the base (10), one end of the conduit (40) is connected to the collecting bucket (35), and the other end of the conduit (40) is connected to the receiving box (50).

8. The outdoor high-altitude sampling device for Cercis chinensis according to claim 7, characterized in that: The receiving box (50) comprises a box body (51) and an air pump (54); a filter screen (42) and a mounting frame (53) are fixedly installed inside the box body (51); the air pump (54) is fixedly installed on the mounting frame (53); and the air pump (54) is used to generate negative pressure inside the box body (51).

9. The high-altitude sampling device for Cercis chinensis in the field according to claim 1, characterized in that: The manipulator device (20) comprises a first manipulator arm (21), a second manipulator arm (22) and a third manipulator arm (23); the lower end of the first manipulator arm (21) is rotatably mounted on the base (10); the upper end of the first manipulator arm (21) is rotatably connected to one end of the second manipulator arm (22); the other end of the second manipulator arm (22) is rotatably connected to one end of the third manipulator arm (23); the other end of the third manipulator arm (23) is an operating end; and the operating end of the third manipulator arm (23) is connected to the sampling and collecting mechanism (30).

10. A method for sampling Cercis chinensis from high altitude in the field, characterized in that: The following steps are involved: S101, moving the outdoor high-altitude sampling device for redbud wood to a target collection point, and when the sampling device reaches the target collection point, the manipulator device (20) controls the sampling and collection mechanism (30) to move so that the sampling and collection mechanism (30) is close to the branches and leaves of the redbud wood to be sampled; S102, using the manipulator device (20) to control the movement of the sampling and collecting mechanism (30), so that the branches and leaves of the redbud wood are inserted into the grooves on the frame (31), starting the driving motor (26), so that the driving screw (37) drives the saw blade (32) to move toward the branches and leaves of the redbud wood, and using the saw blade (32) to cut the branches and leaves of the redbud wood; S103, after the branches and leaves of the redbud wood are cut, they fall into the collecting bucket (35), and the air pump (54) is started. The air pump (54) generates negative pressure inside the box body (51), so that the branches and leaves of the redbud wood in the collecting bucket (35) enter the receiving box (50) through the conduit (40).
