UWB-based agricultural unmanned vehicle with anti-collision mechanism

The utility model belongs to the technical field of unmanned vehicles, in particular to a UWB-based agricultural unmanned vehicle with an anti-collision mechanism, and provides the following scheme that the agricultural unmanned vehicle comprises an unmanned vehicle body, two sets of fixing frames are installed at the front end of the unmanned vehicle body from top to bottom, and first springs are connected to the two sides of the front end of each fixing frame in a sleeving mode; and first sliding blocks are fixedly mounted on the opposite sides of the two groups of first springs. Through the arrangement of the first spring, the first sliding block and the second sliding block, when the front portion of the baffle is collided by an obstacle, the first sliding block is pushed to slide towards the two sides on the fixing frame, the first spring is used for releasing force to the first sliding block, and therefore shock absorption is conducted; when the unmanned vehicle collides, the second sliding block is pus
