Engineering construction stirring machine capable of conveniently opening and closing feeding opening

The engineering construction stirring machine comprises a stirring device body, a first discharging plate and a second torsion spring, the left end of the top of the stirring device body is provided with a first feeding port, and the right end of the top of the stirring device body is provided with a second feeding port; one end of the second torsion spring is connected with the supporting rod, and the other end of the second torsion spring is connected with the second feeding port. According to the engineering construction stirring machine capable of conveniently opening and closing the feeding opening, a worm is arranged, materials are fed through the interior of the first feeding opening, then a first discharging plate rotates through the worm, meanwhile, a first torsion spring deforms, the worm drives a worm wheel to rotate, and therefore a second discharging plate is opened; the materials in the second feeding hole fall into the stirring box, so that the purpose of conveniently opening and closing the fe
