[0025] A first transmission shaft 5 is installed in the middle of the proportioning box 1, and a second transmission shaft 9 is installed at the bottom of the proportioning box 1. One end of the shaft of the first transmission shaft 5 is provided with a brake motor 11 installed on the proportioning box 1, and the first transmission shaft 5 and the second transmission shaft 9 are connected by a transmission belt 8. By controlling the operation of the brake motor 11, the first transmission shaft 5 is driven to rotate, and the second transmission shaft 9 is driven to operate synchronously by utilizing the transit transmission of the transmission belt 8, thereby promoting the linkage operation of the components on the two sets of shafts to perform the mixing and proportioning process of the chemical materials.

[0026] The first transmission shaft 5 is provided with a plurality of sets of horizontal stirring paddles 6 along the shaft direction thereof, and a plurality of sets of vertical stirring paddles 7 are arranged between two adjacent sets of horizontal stirring paddles 6. The first transmission shaft 5 is provided with a linkage mechanism for driving the vertical stirring paddles 7 along the shaft direction thereof.

Then, the lifting electric push rod 35 is controlled to telescopically brake to push the opening and closing door 36 to open and close, and the chemical raw materials in the feed hopper 33 are discharged into the proportioning box 1. Synchronously, in this way, various raw materials of the chemical materials are quantitatively weighed and discharged into the proportioning box 1 in sequence;

[0032] While the second transmission shaft 9 rotates, it drives the stirring screw 10 to operate, and the spiral symmetrical propulsion of the stirring screw 10 is used to promote the spiral symmetrical stirring of the chemical materials at the bottom, which plays an auxiliary stirring and pushing role, and improves the diversification of the mixing ratio. By utilizing the forward and reverse cyclic rotation of the brake motor 11, the components on the two sets of shafts are driven to operate forward and reverse, and the chemical materials are subjected to a diversified and sufficient mixing and proportioning process. After the mixing and proportioning is completed, the discharge port 4 is opened, and the chemical materials after proportioning are mechanically pushed and discharged by utilizing the spiral symmetrical stirring of the stirring screw 10.
