The invention provides a material distribution spreader with a finishing function, and belongs to the technical field of concrete preformed unit production. The material distribution spreader with thefinishing function comprises a material hopper, a bin door, a travelling assembly, a material distribution disc and a finishing assembly. A discharging port is formed in the lower end of the materialhopper, the bin door is arranged at the discharging port, the discharging port is closed or opened by a driving component of the bin door; and the travelling assembly is used for driving the materialhopper to move in a reciprocating mode along the concrete preformed unit production line; the material distribution disc is installed onthe lower part of the material hopper, the material distribution disc is driven to rotate through a material distribution motor and is used for uniformly distributing the materials in the material distribution disc into a mould cavity, and the material distribution motor is connected with the travelling assembly; the finishing assembly is installed on one side of the travelling assembly and is used for finishing concrete products which finishes the material distribution. According to the material distribution spreader with the finishing function, material distribution and finishing are conducted simultaneously, the surface quality of the product is improved, the production period is shortened, the production efficiency is improved, and the manual labor intensity is lowered.
