[0026] like Figure 1-4 As shown, a fireworks and firecrackers drug mixing device comprises:

[0027] The mixing barrel 1 has a feeding port 12 at its first end;

[0028] The containing assembly 2 comprises a containing frame 21 stacked on the second end of the mixing barrel 1, the containing frame 21 is fixedly connected to a conveying pipe 22, the conveying pipe 22 is fixedly connected to a fan-shaped discharge plate 23, and the fan-shaped discharge plate 23 is located in the mixing barrel 1;

[0029] A protruding ball 24 is provided on the containing frame 21, a ring slider 20 is slidably connected to the mixing barrel 1, a knocking plate 201 is provided on the ring slider 20, and the knocking plate 201 slides and knocks the protruding ball 24;

[0030] The plurality of fan-shaped discharge plates 23 discharge materials in a staggered manner so that the materials are mixed in the mixing barrel 1 .

[0031] Specifically, the first end of the mixing barrel 1 (with Figure 4For reference, the first end is the lower end and the second end is the upper end) is provided with a discharge port 12, and raised balls 24 are arranged in a circular array on the outer wall of the holding frame 21. When mixing gunpowder, multiple strands of powdered gunpowder are placed on multiple holding frames 21 respectively and superimposed on the second end of the mixing barrel 1, and then the bright bead gunpowder is placed on another holding frame 21 and superimposed on the top of the remaining holding frames 21, and then the end cover 214 is set on the topmost holding frame 21 for shielding, and the hand-grip ring slider 20 slides so that the elastic knocking plate 201 vibrates the multiple raised balls 24, so as to prompt the multiple strands of powdered gunpowder and bright bead gunpowder in the holding frame 21 to be dispersed from the multiple fan-shaped discharge plates 23 along the conveying pipe 22 respectively, so that the multiple strands of powdered gunpowder naturally fall and mix with the falling bright bead gunpowder, and are discharged from the discharge port 12 to complete the mixing. The mixing process is assisted by natural falling, the friction generated in the mixing process is small, and the process is safer.

[0032] In the above technical scheme, multiple strands of powdered gunpowder and bright bead gunpowder are placed in a containing frame 21, and the containing frame 21 is superimposed on the mixing barrel 1, and then vibrated to make the powdered gunpowder and bright bead gunpowder sprinkled and fallen in the mixing barrel 1 along the fan-shaped discharge plate 23, so as to mix the powdered gunpowder and bright bead gunpowder. The mixing process is assisted by natural falling, and the friction generated in the mixing process is relatively small.

[0033] As an embodiment further provided by the present invention, a chute 11 is provided on the mixing barrel 1, a connecting pipe 231 is provided on the fan-shaped discharge plate 23, the connecting pipe 231 is fixedly connected with the conveying pipe 22, and the fan-shaped discharge plate 23 is slidably connected to the chute 11;

[0034] A sliding shield 25 is provided on the connecting pipe 231 .

[0035] Specifically, before mixing, the connecting tube 231 can be slid along the slide groove 11 as needed to adjust the position of the fan-shaped discharge plate 23 so that different fan-shaped discharge plates 23 are staggered, thereby changing the falling path of the gunpowder, and changing the path according to the weight and falling speed of the gunpowder to assist in the mixing of the powdered gunpowder.

[0036] As a further embodiment provided by the present invention, a fabric ring 13 is provided on the feed opening 12;

[0037] Elastic bands 131 are arranged on the fabric ring 13 in a linear array, and the elastic band 131 in the middle has a larger diameter than the elastic bands 131 at both ends.

[0038] Specifically, the fabric ring 13 collects the mixed gunpowder after it falls. The fabric ring 13 plays a role of buffering and gathering. Elastic bands 131 are arranged in a linear array on the fabric ring 13. The elastic bands 131 bind the fabric ring 13 together to adjust the feeding speed and prevent the bright bead gunpowder from falling too fast. The diameter of the middle elastic band 131 is larger than the elastic bands 131 at both ends to ease the gunpowder when the feeding is restricted and to limit the gunpowder at the same time when discharging.

[0039] As an embodiment further provided by the present invention, the mixing barrel 1 is provided with legs 3 for supporting the mixing barrel 1 .

[0040] As a further embodiment provided by the present invention, a material discharge block 211 is provided in the fan-shaped discharge plate 23, a slope 212 is provided on the material discharge block 211, and arc surfaces 213 are symmetrically provided on the material discharge block 211 along the slope 212;

[0042] Specifically, rubber strips are provided on both sides of the adjustment plate 210 so that the adjustment plate 210 can be damped and slidably connected to the sliding groove 2131 opened on the arc surface 213. When the containing frame 21 vibrates, the gunpowder will enter the conveying pipe 22 along the discharge block 211 and the arc surface 213. When the gunpowder needs to be adjusted, the adjustment plate 210 is held by hand and slid along the sliding groove 2131 to adjust the opening size of the fan-shaped discharge plate 23 and the conveying pipe 22.

[0043] Working principle: first, hold the adjustment plate 210 and slide it along the sliding groove 2131 to adjust the opening size of the fan-shaped discharge plate 23 and the conveying pipe 22, then place multiple strands of powdered gunpowder on multiple holding frames 21 respectively, and overlap them on the second end of the mixing barrel 1, and then place the bright bead gunpowder on another holding frame 21 and overlap it on the top of the remaining holding frames 21, then hold the ring slider 20 and slide it to make the elastic knocking plate 201 vibrate the multiple raised balls 24, so as to prompt the multiple strands of powdered gunpowder and bright bead gunpowder in the holding frame 21 to be dispersed from the multiple fan-shaped discharge plates 23 along the conveying pipe 22 respectively, and the staggered fan-shaped discharge plates 23 make the multiple strands of powdered gunpowder fall naturally and mix with the falling bright bead gunpowder.

[0044] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
