[0001] The present invention relates to the technical field of brick making, and particularly relates to a mother - son vehicle transportation device for a brick - making production line. Background Art

[0002] In the brick - making production process, after the bricks go through processes such as forming and stacking, the stacked brick racks need to be accurately transferred from the conveyor line to the drying area for subsequent processing. Currently, mother - son vehicle equipment is generally used in brick - making production lines to complete the transfer task of brick racks between the conveyor line and the drying area. The deficiencies of existing mother - son vehicle equipment are as follows: The walking drive of the mother vehicle on the track, as well as the extending and retracting actions of the son vehicle on the mother vehicle, often rely on relatively independent drive mechanisms. There is a lack of an effective coordinated control mechanism between these drive mechanisms. The walking drive mechanism and the transposition drive mechanism may operate simultaneously, increasing the risk of mechanical interference of the equipment; moreover, the design of this dual - drive mechanism results in a relatively large size and high cost of the mother - son vehicle.
