[0021] The weighing assembly 3 includes a pair of support rods 6 fixed to the top of the mixing chamber 2. A weighing module 7 is fixed to the top of the support rods 6. A weighing chamber 8 is disposed between the two weighing modules 7. Connecting plates 9 are fixed to both ends of the weighing chamber 8, and the bottom of the connecting plates 9 is fixed to the top of the weighing modules 7. A valve 10 is disposed at the bottom of the weighing chamber 8. Solid or liquid ingredients are conveyed into the weighing chamber 8 through the liquid conveying assembly 4 and the solid conveying assembly 5. At this time, the valve 10 is in the closed state, so that the ingredients are concentrated inside the weighing chamber 8. The weight of the ingredients inside the weighing chamber 8 is pressurized by the connecting plates 9 on the weighing modules 7. At this time, the weight of the ingredients in the weighing chamber 8 can be determined very accurately through the weighing modules 7, and the data is transmitted to an external data system. When the required weight is reached, the conveying of the liquid conveying assembly 4 and the solid conveying assembly 5 is turned off, and the valve 10 is opened at the same time, thereby completing the quantitative addition of the emulsion explosive ingredients.

[0022] The liquid conveying assembly 4 includes a liquid storage tank 11, with a water pump 12 threadedly connected to the top of the liquid storage tank 11. The conveying end of the water pump 12 is interference-fitted with a pipe 13.

By starting the first motor 17, the first motor 17 drives the auger blade 16 to rotate, and the rotation of the auger blade 16 drives the solid material to move from bottom to top inside the conveying pipe 15, and is conveyed to the weighing bin 8 through the top outlet.

The rotating end of the second motor 19 passes through the outer surface of the rotating shaft 20 fixed to the mixing chamber 2 and has several stirring rods 21 arranged at equal intervals. By starting the second motor 19, the second motor 19 drives the rotating shaft 20 to rotate, and the rotation of the rotating shaft 20 drives the stirring rods 21 to stir the inside of the mixing chamber 2.

[0025] The outer surface of the pipe 13 is fitted with a fixing plate 22 that is welded to the mixing chamber 2. The fixing plate 22 can limit and fix the pipe 13.

[0026] The bottom center of the mixing chamber 2 is fixed with a discharge port 23, which facilitates the flow of the mixed ingredients out through the discharge port 23.

[0027] The four corners of the bottom of the base 1 are fixed with support legs 24 to support the entire device.

[0028] When using this device, the liquid ingredients are poured into the mixing chamber 2, the water pump 12 is started, and the liquid ingredients are transported to the weighing chamber 8 through the pipe 13. The weight output by the weighing module 7 is observed. When the liquid ingredients reach the set weight, the valve 10 is opened, and the liquid ingredients are transported into the mixing chamber 2 through the inlet at the top of the mixing chamber 2. The solid ingredients are poured into the solid storage chamber 14, the first motor 17 is started, and the first motor 17 drives the auger blades 16 to rotate. The solid ingredients are transported into the weighing chamber 8 through the conveying pipe 15 and the auger blades 16. The weight output by the weighing module 7 is observed. When the solid ingredients reach the set weight, the valve 10 is opened, and the solid ingredients are transported into the mixing chamber 2 through the inlet at the top of the mixing chamber 2. The second motor 19 is started, and the rotating shaft 20 and the stirring rod 21 stir the solid and liquid ingredients in the mixing chamber 2. After the mixture is evenly stirred, the discharge port 23 is opened, and the mixed ingredients in the mixing chamber 2 flow out through the discharge port 23.
