Reaction tank convenient for material injection

The utility model discloses a reaction tank convenient to inject, which belongs to the field of reaction tanks and comprises a reaction tank body and a stirring shaft, supporting legs are respectively arranged on four sides of the bottom of the reaction tank body, a feed port is arranged on the top surface of the reaction tank body, and the reaction tank body is matched with an injection mechanism arranged on the reaction tank body for use. A second driving motor can drive a stirring shaft to rotate, raw materials fed into a feeding hopper are scattered through a stirring rod in the rotating process, the situation that the raw materials are blocked when being fed into a reaction tank body is avoided, and after the scattered raw materials falling into a material injection tank are conveyed into the reaction tank body through a first driving motor after driving a conveying shaft to rotate, the raw materials fall into the reaction tank body. According to the feeding device for the reaction tank, raw materials in
