[0020] See also Figure 1-3As shown, the on-site mixing device for emulsion explosives of the utility model embodiment comprises a base 1, an electronic scale 2 installed at the center position of the upper end of the base 1, and a packaging tube 3 located at the upper end of the electronic scale 2. The four corners of the upper end of the base 1 are vertically fixed with fixed rods 4, and the four fixed rods 4 are threadedly sleeved with limiting blocks 5. The upper ends of the four limiting blocks 5 are movably connected with movable blocks 6. A clamping mechanism 7 is provided between the corresponding two movable blocks 6. The two clamping mechanisms 7 are respectively located on both sides of the packaging tube 3. The outer sides of the upper ends of the four fixed rods 4 are threadedly sleeved with lifting blocks 9, and a limiting mechanism 8 is provided on one side of one lifting block 9. The side of the limiting mechanism 8 away from the lifting block 9 corresponds to the upper end of the packaging tube 3. The packaging tube 3 is stably clamped by the two clamping blocks, and the packaging tube 3 is not supported, so that the packaging tube 3 acts completely on the electronic scale 2 to ensure the weighing accuracy. At the same time, the limiting rod 81 can also press down the upper end of the packaging tube 3 through the force of the torsion spring 85, thereby further ensuring the stability of the packaging tube 3 and having stronger adaptability.

[0021] The two clamping mechanisms 7 each include a screw rod 71, two guide rods 72, a clamping block 73 and a connecting plate 74. The two ends of the connecting plate 74 are respectively fixedly connected to the two movable blocks 6. The screw rod 71 is threadedly connected to the connecting plate 74. The two guide rods 72 are movably sleeved with the connecting plate 74. The two guide rods 72 are fixedly connected to the clamping block 73 at one end close to the packaging tube 3. The outer center position of the clamping block 73 is rotatably connected to one end of the screw rod 71.

[0022] The limiting mechanism 8 includes a limiting rod 81, a mounting tube 82, two mounting blocks 83, a rotating shaft 84 and two torsion springs 85. The two mounting blocks 83 are respectively fixed on both sides of the corresponding lifting blocks 9. A rotating shaft 84 is rotatably connected between the two mounting blocks 83. One end of the mounting tube 82 is fixedly sleeved with the rotating shaft 84. Torsion springs 85 are fixedly connected between both sides of the mounting tube 82 and the corresponding mounting blocks 83. The two torsion springs 85 are both sleeved on the periphery of the rotating shaft 84. A limiting rod 81 is provided at one end of the mounting tube 82 away from the rotating shaft 84. One end of the limiting rod 81 away from the mounting tube 82 is tightly fitted with the upper edge of the packaging tube 3; the two clamping blocks 73 are both arranged in an arc shape, and the two clamping blocks 73 are symmetrical; one end of the limiting rod 81 is inserted into the inside of the mounting tube 82, and the limiting rod 81 is threadedly connected to the mounting tube 82.

[0023] When the embodiment of the utility model is used, the explosive packing tube is placed vertically on the electronic scale 2, the movable block 6 is slid upward to leave a distance between the movable block 6 and the support block, and the screw rod 71 is rotated. When the screw rod 71 rotates, it will drive the clamping block 73 to move horizontally. The two clamping blocks 73 are stably clamped on the outside of the packaging tube 3. Since the movable block 6 is movably sleeved with the fixed rod 4 and the movable block 6 does not contact the support block, the packaging tube 3 will not be supported, so that the packaging tube 3 completely acts on the electronic scale 2 to ensure the weighing accuracy. The height of the lifting block 9 is adjusted according to the actual height of the packaging tube 3. After the adjustment is completed, the limit rod 81 is rotated to adjust the length of the limit rod 81 so that one end of the limit rod 81 is just in contact with the upper edge of the packaging tube 3. At this time, the limit rod 81 drives the rotating shaft 84 to rotate through the installation tube 82, thereby twisting the torsion spring 85. The limit rod 81 presses down the upper end of the packaging tube 3 through the force of the torsion spring 85, thereby further ensuring the stability of the packaging tube 3. It can adapt to packaging tubes 3 of various specifications and has stronger adaptability. Then, the electronic scale 2 is set to zero, and finally the emulsion explosive raw material is filled into the packaging tube 3, and the amount of explosives is controlled by the value of the electronic scale 2.

[0024] The above shows and describes the basic principles of the present invention. The above are only preferred embodiments of the present invention and are not intended to limit the present invention. The above embodiments and descriptions in the specification are only intended to illustrate the principles of the present invention. Without departing from the scope of the present invention, any modifications, equivalent substitutions and improvements made within the spirit and scope of the present invention should be included in the protection scope of the present invention.
