A dosing device body is fixedly installed at one end of the lifting hydraulic cylinder, and a power supply box is fixedly installed on one side of the dosing device body. In use, adjusting the lifting hydraulic cylinder drives the dosing device body to adjust its height. Through the coordinated arrangement of the power supply box, drying lamp, first motor, first transmission rod, and spiral stirring rod, the drying lamp is electrically connected to the power supply box, and the first motor is connected to the power supply to drive the first transmission rod and spiral stirring rod, thus ensuring sufficient contact between the catalyst and the heat source of the drying lamp, preventing the catalyst from becoming damp and clumping. Through the coordinated arrangement of a second motor, second transmission rod, and spiral discharge rod, the second motor is connected to the power supply to drive the second transmission rod and spiral discharge rod, causing the spiral discharge rod to rotate and discharge material, thus achieving self-feeding.
