The present invention proposes a drop-type uniform material distribution system, including: a furnace body, a material bin, a material distribution device and a driving device, wherein the material distribution device is arranged at the discharge port of the material bin along the horizontal direction, including: a material distribution device A fixed plate and a moving plate for distribution, wherein the fixed plate for distribution is fixedly connected with the inner wall of the furnace body, the moving plate for distribution is arranged above the fixed plate for distribution, and is connected with the driving device, and is driven by the The device drives the moving plate of the cloth to move the cloth. The uniform distribution of granular materials on the plane is realized, and the uniformity of the distribution is ensured by the uniform porous distribution, which ensures the stability of the production quality. Realized the reliability of the furnace seal when distributing materials.
