The invention discloses a raw coal push-pull type coal hopper sampling device and a coal storage system. The raw coal push-pull type coal hopper sampling device comprises a sampling channel arranged in the middle of a coal storage device; upper and lower end faces of the sampling channel are provided with upper and lower sealing plates, and the middle of the upper sealing plate is provided with a notch through which the coal sample can be fallen down; a lead rail is arranged between the upper and lower sealing plates, and a sampling pull box is moveably arranged on the lead rail and moved between the upper and lower sealing plates along the lead rail, thus the fallen coal sample is conveyed out of the sampling channel. The raw coal push-pull type coal hopper guarantees that the raw coal cannot be sprayed out of the sampling bag without control in an operation state, thus the working environment of sampling is greatly improved. 本发明公开了种原煤推拉式落煤斗取样装置及储煤系统包括设置于储煤装置中间的取样通道，所述取样通道的上、下端面分别设置有上、下密封板，且上密封板中间具有缺口，能够使煤样下
