The device can be used for unmanned driving, and working condition one includes harvesting pasture or collecting pasture specimens in the pasture planting area based on the pre-stored map information of the controller, through the control of the controller and the driving of the walking mechanism; working condition two includes that the operator at the remote end issues instructions to the controller through the control panel, and operates the walking mechanism based on the image information fed back by the image collection mechanism (which can be a laser radar), and completes the harvesting and collection of pasture and the collection of specimens. Exemplarily, the controller pre-stores the image information (such as latitude and longitude data) of the to-be-processed pasture planting area, or sets a non-physical fence for the edge of the to-be-processed pasture planting area, the controller controls the walking mechanism to work, so that the whole device walks, the image collection mechanism collects the image information of the pasture, and the controller judges whether the pasture information is correct. If correct, the collection mechanism is first controlled to collect the whole pasture as a specimen, and then the harvesting mechanism is controlled to harvest and collect the pasture.

If correct, the collection mechanism 60 is first controlled to collect the whole pasture as a specimen, and then the harvesting mechanism 50 is controlled to harvest and collect the pasture.

[0054] According to some embodiments of the present application, please refer to Figure 3 and Figure 4 , the harvesting mechanism 50 includes a harvesting bucket 51, a harvesting cutter wheel 52, and a driving member.
