Bucket wheel machine tail car material piling and taking switching device

The utility model discloses a material piling and taking switching device for a tail car of a bucket wheel machine, and relates to the technical field of bucket wheel machines. According to the bucket wheel machine tripper car material piling and taking switching device, the telescopic rod is used for driving the square frame to move, the inclination angle of a material yard conveyor is adjusted, and therefore the bucket wheel machine tripper car material piling and taking switching device can be better matched with a belt conveyor to be used, and meanwhile under the cooperation of the linkage rod and the insertion plate piece, when the material yard conveyor needs to feed materials, the linkage rod drives the insertion plate piece to move upwards, and the material piling and taking switching device is convenient to use. When a stockyard conveyor needs to discharge materials, a linkage rod drives a plate inserting piece to move downwards, the stockyard conveyor extrudes the limiting plate, it is ensured that
