First, the combined gun barrel 3 is placed in the sliding base 2, so that the gunpowder in the material box 4 is loaded into the corresponding combined gun barrel 3 through the telescopic tube 8 and the discharge tube 7, and then the driving assembly 6 is used to drive the sliding base 2 and the combined gun barrel 3 to move intermittently. At the same time, the driving assembly 6 drives the sliding plate 5 to rise, and the sliding plate 5 drives the plug 9 to rise, so that the plug 9 blocks the discharge port at the bottom of the material box 4, thereby preventing the gunpowder from spilling out when the combined gun barrel 3 moves, and ensuring that the amount of gunpowder loaded in each gun barrel is the same.

[0019] The driving assembly 6 includes two driving shafts 63 that are distributed in a mirror image, and the driving shafts 63 are rotatably mounted on both sides of the operating box 1 , and the bottom ends of the two driving shafts 63 are fixedly mounted with first half gears 61 .

[0020] By adopting the above technical solution, the driving shaft 63 drives the first half gear 61 to rotate.

[0021] First tooth plates 62 are fixedly mounted on both sides of the sliding base 2 , and the first half gears 61 are meshed with the corresponding first tooth plates 62 .

[0022] By adopting the above technical solution, the first half gear 61 drives the sliding base 2 and the combined barrel 3 to move by meshing with the first tooth plate 62 .

[0023] Second half gears 65 are rotatably mounted on both sides of the operation box 1 , and second toothed plates 66 are fixedly mounted on both ends of the sliding plate 5 , and the second half gears 65 are meshed with the corresponding second toothed plates 66 .

[0024] By adopting the above technical solution, the second half gear 65 drives the sliding plate 5 to rise by meshing with the second tooth plate 66 .

[0025] Bevel gears 64 are fixedly mounted on the two driving shafts 63 and on one side of the two second half gears 65 , and two adjacent bevel gears 64 are meshed.

[0026] By adopting the above technical solution, the driving shaft 63 drives the second half gear 65 to rotate through the bevel gear 64 .

[0027] A worm gear 68 is fixedly mounted on the top of each of the two driving shafts 63 , and a double-headed worm 69 is rotatably mounted on the top of the operating box 1 , and the double-headed worm 69 is meshed with the worm gear 68 .

[0028] By adopting the above technical solution, the double-headed worm 69 drives the worm wheel 68 to rotate, and the worm wheel 68 drives the driving shaft 63 to rotate.

[0029] A motor 67 is fixedly mounted on one side of the top end of the operating box 1 , and an output end of the motor 67 is fixedly connected to one end of a double-headed worm 69 .

[0030] By adopting the above technical solution, the motor 67 is used to drive the double-headed worm 69 to rotate.

[0031] Two symmetrically distributed slide bars 10 are slidably inserted at the top of the operating box 1 , and the bottom ends of the slide bars 10 are fixedly connected to the upper surface of the sliding plate 5 . Springs 11 are sleeved on the two slide bars 10 .

[0032] By adopting the above technical solution, when the sliding plate 5 rises, the spring 11 is squeezed, and when the second half gear 65 is disengaged from the second tooth plate 66, the rebound force of the spring 11 causes the sliding plate 5 to fall.

[0033] Working principle: When the utility model is in use, the motor 67 is used to drive the double-headed worm 69 to rotate, the double-headed worm 69 drives the worm wheel 68 to rotate, the worm wheel 68 drives the driving shaft 63 to rotate, the driving shaft 63 drives the first half gear 61 to rotate, the first half gear 61 is engaged with the first tooth plate 62, and drives the sliding base 2 and the combined barrel 3 to move intermittently, and at the same time the driving shaft 63 drives the second half gear 65 to rotate through the bevel gear 64, the second half gear 65 is engaged with the second tooth plate 66 to drive the sliding plate 5 to rise, and squeeze the spring 11, the sliding plate 5 drives the feeding tube 7 to rise from the corresponding barrel (the depth of the feeding tube 7 inserted into the barrel 3 is very small, which does not affect the synchronous movement of the sliding base 2 and the combined barrel 3), and at the same time the sliding plate 5 drives the plug 9 to rise, so that The plug 9 blocks the discharge port at the bottom end of the material box 4, thereby preventing gunpowder from spilling out while the combined gun barrel 3 moves, and can also ensure that the amount of gunpowder loaded in each gun barrel is the same. When the combined gun barrel 3 that is not filled with gunpowder moves to just below the discharge pipe 7, the first half gear 61 disengages from the first tooth plate 62, so that the sliding base 2 and the combined gun barrel 3 stop moving. At this time, the second half gear 65 disengages from the second tooth plate 66, and the rebound force of the spring 11 causes the sliding plate 5 to descend, and the sliding plate 5 drives the discharge pipe 7 to descend and insert into the corresponding gun barrel. At the same time, the sliding plate 5 drives the plug 9 to descend, so that the gunpowder in the material box 4 is loaded into the corresponding combined gun barrel 3 through the telescopic tube 8 and the discharge pipe 7, and this cycle is repeated, thereby completing the automatic quantitative gunpowder loading of the combined gun barrel 3.

[0034] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
