The invention discloses a shuttle car charging device. The shuttle car charging device comprises a charging main body, an adjusting lifting main body and a balance main body. A charging conveying beltis arranged on the charging main body. A charging curved plate is arranged on the left side of the charging conveying belt. A plurality of sets of charging supporting plates are distributed on the charging conveying belt. A transverse shaft penetration port is formed in the bottom of the charging main body. A charging adjusting transverse shaft penetrates through the transverse shaft penetrationport, and the rear end of the charging adjusting transverse shaft is fixed in a transverse adjusting groove of the adjusting lifting main body. According to the shuttle car charging device, the more efficient and practical shuttle car charging device is improved, the height of the device is adjusted flexibly and conveniently, shuttle cars of different size specifications can be effectively chargedin an adjusting mode, in addition, materials stacked at a position can be balanced in the charging process, a transfer space of the shutter cars is efficiently used, and the shutter car charging efficiency is effectively improved.
