Knapsack type emulsified-explosive loader adopting site mixing and loading

The invention discloses a knapsack type emulsified-explosive loader adopting site mixing and loading. The knapsack type emulsified-explosive loader is characterized in that a conveying pipe (3) is arranged between an emulsion matrix tank (1) and a static mixer (2); a high-pressure gas cylinder (4) is arranged at the side of the emulsion matrix tank (1) and is fixed with the emulsion matrix tank (1); one gas outlet of the high-pressure gas cylinder (4) is connected with a first gas pipe (5) which is connected with the top end of the emulsion matrix tank (1); another gas outlet of the high-pressure gas cylinder (4) is connected with a second gas pipe (6) which is connected with the top end of a foaming-agent container (10); a discharging hole of the foaming-agent container (10) is communicated with the conveying pipe (3) by a pipeline; and the emulsion matrix tank (1) is externally provided with a positioning bag (8) with an opened upper end in a pocketing manner. The knapsack type emulsified-explosive loader disclosed by the invention has the advantages that emulsion matrix and a foaming agent are conveyed by high-pressure gas provided by the high-pressure gas cylinder, and the knapsack type operation mode can be adopted, so that the production cost is effectively reduced.
