[0025] The present invention can be explained in detail by the following examples, the purpose of which is to disclose the present invention and to protect all technical improvements within the scope of the present invention.

[0026] Example 1, combined with the attached Figures 1 to 8 , the automatic discharging device for a pyrotechnic powder automatic mixer is installed on the mixing body 33 and is used to receive materials; it includes a horizontal shaft 7, one end of the horizontal shaft 7 is connected to a sliding sleeve assembly 8, the side of the sliding sleeve assembly 8 is connected to a barrel holder 10, the other end of the horizontal shaft 7 is connected to a vertical shaft 4, the top of the vertical shaft 4 is installed with a power mechanism, the power mechanism includes a mounting box body 1 arranged at the top of the vertical shaft 4, an electric push rod 2 is installed inside the mounting box body 1, and the top of the electric push rod 2 is connected to the vertical shaft 4 by pushing a crank 3; the mounting box body 1 is arranged at the top of the mixing body 33 On the frame, a barrel blocker 34 is installed on the frame of the mixing body 33 on the side away from the installation box body 1, which contacts the barrel holder 10 through the barrel blocker 34, thereby blocking the barrel holder 10, and connecting the top of the electric push rod 2 with one end of the pushing crank 3 through a rotatable shaft, and the other end of the pushing crank 3 is connected to the vertical shaft 4 through a fixed pin, so that when the electric push rod 2 is extended, the pushing crank 3 can be rotated, and the vertical shaft 4 is driven to rotate under the action of the pushing crank 3, and the rotation angle of the pushing crank 3 determines the rotation angle of the horizontal axis 7.

[0027] The sliding sleeve assembly 8 includes a mounting shaft 19, and a screw 20 is provided at the bottom end of the mounting shaft 19. The bottom end of the screw 20 passes through and extends to the bottom of the horizontal axis 7 and is connected to a fixing nut 9. The setting of the mounting shaft 19 enables the sliding sleeve assembly 8 to move synchronously under the action of the horizontal axis 7 in the early stage, and enables the sliding sleeve assembly 8 to rotate in the later stage; the outside of the mounting shaft 19 is connected to a sleeve 32 through a linear bearing 25, and an elastic retaining ring 26 is also installed between the sleeve 32 and the mounting shaft 19. The outside of the sleeve 32 is provided with a cylindrical upper sliding sleeve 24, and the outside of the mounting shaft 19 below the sleeve 32 is provided with a cylindrical lower sliding sleeve 23. The lower end face of the upper sliding sleeve and the upper end face of the lower sliding sleeve are meshing toothed surfaces. The upper and lower sliding sleeves are meshingly arranged, and the lower sleeve 23 and the upper sliding sleeve 24 can rotate relative to each other, thereby supporting the barrel holder 10.

[0028] A material receiving barrel 11 is placed inside the barrel holder 10, and the barrel holder 10 is supported by the sliding sleeve assembly 8, so that the material receiving barrel 11 installed inside the barrel holder 10 can be tightly fastened at the position of the discharge port of the gunpowder automatic mixer.

[0029] The outside of the vertical shaft 4 is connected to an outer tube 15 through a bearing 14, and the outer tube 15 is fixedly installed by a mounting assembly 5. The mounting assembly 5 includes a U-shaped part 16 installed on the outside of the outer tube 15. The top of the U-shaped part 16 is fixed with a fixing plate 17 through a locking nut 18. The whole is installed on the frame of the automatic pyrotechnic powder mixer through the mounting assembly 5, and the barrel tray 10 is set below the automatic pyrotechnic powder mixer.

[0030] A box cover 6 is installed on the top of the installation box body 1 to prevent debris from entering the interior of the installation box body 1. A cover 13 is buckled on the top of the sliding sleeve assembly 8 to facilitate closing the sliding sleeve assembly 8 when not in use.

[0031] The barrel holder 10 is configured as a funnel-like structure, and a connecting frame 31 is installed on the side of the barrel holder 10. The barrel holder 10 includes a bottom ring 27 and a top ring 29. The bottom ring 27 and the top ring 29 are connected by a connecting rod 28. An L-shaped support plate 30 is distributed at the bottom end of the bottom ring 27 to facilitate the installation of the barrel pad 12. The barrel pad 12 is fixed to the inside of the bottom ring 27 through the L-shaped support plate 30. Different specifications of receiving barrels 11 use barrel pads 12 of different specifications, which improves the installation stability of the receiving barrel 11.

[0032] A connecting plate 21 is provided on the side of the sliding sleeve assembly 8, and the connecting plate 21 is provided on the side of the sleeve 32, so that when the upper sliding sleeve 24 is raised, the connecting plate 21 can be driven to rise. Screw holes 22 are provided on the connecting plate 21 and the connecting frame 31, which facilitates the installation and disassembly of the sliding sleeve assembly 8 and the barrel tray 10.

[0033] When in use, the outer tube 15 is fixed to the frame of the mixing body 33 through the installation component 5, so that the barrel holder 10 is located on the lower side of the mixing body 33, and then the barrel stopper 34 is installed on the other side of the lower side of the mixing body 33. The barrel stopper 34 is configured as a push rod to mainly block the barrel holder 10. When the barrel holder 10 contacts the barrel stopper 34, the material receiving barrel 11 is just below the discharge end of the mixing body 33, and thus installed.

[0034] By extending the electric push rod 2, the electric push rod 2 drives the push crank 3 to rotate with the vertical axis 4 as the center, and at the same time drives the vertical axis 4 to rotate. The rotation of the vertical axis 4 drives the horizontal axis 7 to rotate, thereby driving the barrel holder 10 to move. The material receiving barrel 11 installed inside the barrel holder 10 is blocked by the barrel blocker 34 so that it reaches the bottom of the discharge end of the mixing body 33. At this time, the electric push rod 2 continues to extend, and the setting of the barrel blocker 34 prevents the barrel holder 10 and the material receiving barrel 11 from rotating. Due to the structural setting of the lower sleeve 23 and the upper sleeve 24 inside the sleeve assembly 8, the upper sleeve 24 will not move, and the lower sleeve 23 moves along with the horizontal axis. 7 continues to move, thereby causing the upper sliding sleeve 24 to rotate along the mounting shaft 19, thereby causing the vertical shaft 4 to continue to rotate. At this time, when the barrel holder 10 and the receiving barrel 11 cannot rotate, the lower sleeve 23 and the upper sliding sleeve 24 can move relative to each other, thereby causing the upper sliding sleeve 24 to be lifted by the lower sleeve 23, and a gap is generated between the lower sleeve 23 and the upper sliding sleeve 24, that is, the position of the upper sliding sleeve 24 is raised, thereby driving the position of the barrel holder 10 to rise, so that the top of the receiving barrel 11 is tightly buckled with the bottom of the mixing body 33. After receiving the material, the electric push rod 2 is reset, and the receiving barrel 11 can be taken out from the bottom of the mixing body 33, thereby completing the unloading operation.

[0035] Example 2, as Figure 9As shown, the structure of this embodiment differs from that of embodiment 1 in that the power mechanism is different. Specifically, the power mechanism in this embodiment includes a transfer box 35 arranged at the top end of the vertical shaft 4. The interior of the transfer box 35 is slidably connected to a transmission rod 36. The top end of the transmission rod 36 inside the transfer box 35 is connected to the vertical shaft 4 through a push-on second 37, and the top end of the transmission rod 36 outside the transfer box 35 is connected to an electric push rod second 38. The transfer box 35 is set on the frame of the mixing body 33. A barrel blocker 34 is installed on the frame of the mixing body 33 away from the installation box body 1. The barrel blocker 34 contacts the barrel holder 10, thereby blocking the barrel holder 10. The electric push rod 2 38 and the transmission rod 36, as well as the transmission rod 36 and the pushing crank 1 3 are connected through a rotatable shaft. The other end of the pushing crank 1 3 is connected to the vertical shaft 4 through a fixed pin. Therefore, when the electric push rod 2 38 is extended, the pushing crank 2 37 can be rotated, and the vertical shaft 4 is driven to rotate under the action of the pushing crank 1 3. The rotation angle of the pushing crank 2 37 determines the rotation angle of the horizontal axis 7.

[0036] In a specific application of this embodiment, the outer tube 15 is fixed to the frame of the mixer body 33 by the mounting assembly 5, so that the barrel holder 10 is located on one side below the mixer body 33, and then a barrel stopper 34 is installed on the other side below the mixer body 33. The barrel stopper 34 is configured as a push rod to mainly block the barrel holder 10. When the barrel holder 10 contacts the barrel stopper 34, the material receiving barrel 11 is just below the discharge end of the mixer body 33, thereby performing the installation.

[0037] By extending the electric push rod 2 38, the electric push rod 2 38 drives the push crank 1 37 to rotate with the vertical axis 4 as the center, and at the same time drives the vertical axis 4 to rotate. The rotation of the vertical axis 4 drives the horizontal axis 7 to rotate, thereby driving the barrel holder 10 to move. The material receiving barrel 11 installed inside the barrel holder 10 is blocked by the barrel blocker 34 so that it reaches the bottom of the discharge end of the mixing body 33. At this time, the electric push rod 2 38 continues to extend, and the setting of the barrel blocker 34 prevents the barrel holder 10 and the material receiving barrel 11 from rotating. Due to the structural setting of the lower sleeve 23 and the upper sleeve 24 inside the sliding sleeve assembly 8, the upper sleeve 24 will not move, and the lower sleeve 23 moves with The movement of the horizontal axis 7 continues to move, thereby causing the upper sliding sleeve 24 to rotate along the mounting axis 19, thereby causing the vertical axis 4 to continue to rotate. At this time, when the barrel holder 10 and the receiving barrel 11 cannot rotate, the lower sleeve 23 and the upper sliding sleeve 24 can move relative to each other, thereby causing the upper sliding sleeve 24 to be lifted by the lower sleeve 23, and a gap is generated between the lower sleeve 23 and the upper sliding sleeve 24, that is, the position of the upper sliding sleeve 24 is raised, thereby driving the position of the barrel holder 10 to rise, so that the top of the receiving barrel 11 is tightly buckled with the bottom of the mixing body 33. After receiving the material, the electric push rod 2 38 is reset, and the receiving barrel 11 can be taken out from the bottom of the mixing body 33, thereby completing the unloading operation.

[0038] The power mechanism used in Example 1 is a modification based on the existing equipment (old equipment). Due to the limitations of installation space and location, it is preferred to set the power mechanism vertically upward. However, in actual construction, a strict seal will also be made to completely separate the power mechanism from the mixing body (pyrotechnic powder automatic mixer) to ensure safety during production.

[0039] The power mechanism used in Example 2 is suitable for newly built equipment. When newly built, a well-sealed power room will be built next to the mixing body. The power mechanism is installed in the power room, so that the power mechanism and the mixing body are completely separated, ensuring high safety in the production of pyrotechnic powder.

[0040] The parts of the present invention that are not described in detail are prior art. Although the present invention is specifically demonstrated and introduced in conjunction with the preferred embodiments, there are many methods and approaches to implement the technical solution. The above is only a preferred embodiment of the present invention. However, those skilled in the art should understand that various changes can be made to the present invention in form and details without departing from the spirit and scope of the present invention as defined by the appended claims, and all of these are within the scope of protection of the present invention.
