The invention discloses a large-particle-size earth material oversize stone removal device which comprises a bar-type vibration feeder and a screening building. The screening building is divided into three layers which are the receiving layer, the equipment layer and the discharging layer from top to bottom. A receiving hopper is arranged inside the receiving layer. An upper discharging opening is formed in the lower end of the receiving hopper. The equipment layer is provided with the bar-type vibration feeder. The feeding end of the bar-type vibration feeder is right opposite to the upper discharging opening. A lower discharging opening is formed in the equipment layer. The lower discharging opening is right opposite to a discharging opening of the bar-type feeder. The discharging layer is internally provided with a discharging bin. The discharging bin is located under the lower discharging opening. According to the large-particle-size earth material oversize stone removal device, the removal efficiency of large-particle-size earth material oversize stone is remarkably improved, and meanwhile the good removal quality is ensured; the structure is quite stable and reliable, and installation and debugging are rapid and convenient; the maximum earth material particle size can be controlled within the allowed range, and grinding is compact, so that the high compaction degree and the good seepage-proofing effect are obtained, practicability is high, and economic benefits are high.
