[0002] In the on-site mixing process of emulsion explosives, the ratio of sensitizer and latex matrix must be accurate in order to produce qualified emulsion explosives.

[0003] However, in existing emulsion explosive loading equipment, the emulsion matrix and sensitizer are transported using independent pumping systems. The sensitizer pump and matrix pump operate independently and are controlled by the control program of the control system. However, in actual operation, it is very difficult to achieve the proportional movement of the matrix pump and the sensitizer pump. In addition, due to the fluctuation of system pressure, uneven mixing of emulsifier and latex matrix often occurs. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a linkage pump proportioning adjustment device for mixed explosives. Through the arrangement of connecting rods and sliders, the position of the slider on the connecting rod can be adjusted according to actual needs, thereby enabling the active pump and the driven pump to pump the emulsion matrix and sensitizer separately according to the proportion, thus improving the accuracy of the pumping ratio.

[0010] And a control mechanism, which is used to control the position of the slider on the connecting rod along the length of the connecting rod.
