[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 In this embodiment of the utility model, a multi-shot throwing device for a drone includes a support 10. A mounting lug 11 for connecting to the drone body is bolted to the middle of the top of the support 10. Storage boxes 20 for storing the thrown items are installed at both ends of the bottom of the support 10. A door 21 for opening and closing is rotatably connected to the side wall of the storage box 20. A pull plate 22 for pulling is installed at one end of the door 21.

[0026] See Figure 3 The inner wall of the storage box 20 is equipped with a partition plate 50 for dividing the inner wall space of the storage box 20, and a connecting component for fixing is installed at the bottom of the partition plate 50.

[0027] The storage box 20 is rotatably connected to a connecting shaft 40 for rotating the partition plate 50. A docking component that mates with the partition plate 50 is installed on the connecting shaft 40. By cooperating with the docking component, the partition plate 50 is installed on the connecting shaft 40, which divides the space inside the storage box 20 into multiple storage chambers, thereby storing multiple items. An adjustment component is installed inside the connecting shaft 40 for adjusting the docking component. The adjustment component assists in the installation of the connecting component and the docking component, making it easy to install and disassemble. A feeding component is installed at the bottom of the storage box 20, which is opened by the partition plate 50. When the partition plate 50 rotates to the bottom and squeezes the feeding component, the feeding component is opened, allowing the items stored between the two partition plates 50 to be fed out.

[0028] See Figure 2 A drive assembly for driving the connecting shaft 40 to rotate is installed at the bottom center of the support 10. The drive assembly can drive the partition plate 50 to rotate inside the storage box 20 by rotating the connecting shaft 40, thereby enabling the sequential feeding and throwing of the materials stored between the two partition plates 50, and enabling multiple feedings.

[0029] See Figure 4 and Figure 7The connecting assembly includes a docking bar 52, a main insertion rod 54, and a secondary insertion rod 55. The docking bar 52, used for insertion and fixing, is fixedly connected to the bottom outer wall of the partition plate 50. The bottom outer wall of the docking bar 52 has multiple linearly arranged fixing grooves. An adjusting seat 53 is fixedly connected to the inner wall of the fixing groove. The main insertion rod 54 is slidably connected to the inner wall of the adjusting seat 53. A first spring 56 for resetting is fixedly connected to the wall surface opposite to the main insertion rod 54 and the adjusting seat 53. A first sliding hole is opened at both ends of the outer wall of the main insertion rod 54 along its vertical axis. The secondary insertion rod 55 is slidably connected to the inner wall of the first sliding hole. A second spring 57 is fixedly connected to the wall surface opposite to the first sliding hole of the secondary insertion rod 55. The cross-section of the tail ends of the main insertion rod 54 and the secondary insertion rod 55 is arc-shaped.

[0030] See Figure 6 and Figure 8 The docking assembly includes a mounting strip 42, a insertion groove 43, and an insertion cavity 44. The mounting strip 42 is arranged in a circular pattern and fixedly connected to the outer wall of the connecting shaft 40. A docking groove of the same length as the mounting strip 42 is opened in the mounting strip 42. The insertion groove 43 is arranged linearly and opened on the outer wall of the connecting shaft 40 and located on the inner wall of the docking groove. The insertion cavity 44 is opened at both ends of the inner wall of the vertical axis of the insertion groove 43. The docking strip 52 is adapted to the docking groove on the mounting strip 42. The main insertion rod 54 and the auxiliary insertion rod 55 are adapted to the insertion groove 43 and the insertion cavity 44, respectively. When the insertion is fixed, the partition plate 50 is inserted into the docking groove on the mounting strip 42 through the docking strip 52 for fixation. The main insertion rod 54 is inserted into the insertion groove 43 by the elastic force of the first spring 56, and the auxiliary insertion rod 55 is inserted into the insertion cavity 44 by the elastic force of the second spring 57 for fixation. Thus, the partition plate 50 is fixed on the outer wall of the connecting shaft 40.

[0031] See Figure 2 and Figure 3The drive assembly includes a servo motor 31, a drive gear 34, and a driven gear 35. The servo motor 31 is fixedly connected to the middle of the inner wall of the drive housing 30. A rotating shaft 32 is mounted on the output end of the servo motor 31, and a fixed plate 33 is fixedly connected to the middle of the inner wall of the drive housing 30. The drive gear 34 and the driven gear 35 are respectively rotatably connected to the middle and both ends of the outer wall of the fixed plate 33 on the inner wall of the drive housing 30. The driven gear 35 meshes with the outer wall of the drive gear 34. The drive gear 34 is fixedly connected to the tail end of the rotating shaft 32. A transmission shaft 36 is fixedly connected to the axis of the driven gear 35, and a first rotating shaft is fixedly connected to the tail end of the transmission shaft 36. The first rotating disk 37 and the second rotating disk 41 are fixedly connected to the tail end of the connecting shaft 40. The outer walls of the first rotating disk 37 and the second rotating disk 41 are fitted with pulleys 38 for transmission. When it is necessary to rotate the connecting shaft 40 and the partition plate 50 installed on it, the servo motor 31 is turned on. The servo motor 31 can drive the drive gear 34 to rotate through the rotating shaft 32. The drive gear 34 drives the driven gear 35 meshing with it to rotate. Then, through the transmission shaft 36, the first rotating disk 37 and the pulleys 38, the second rotating disk 41 is driven to rotate. The second rotating disk 41 can then drive the partition plate 50 to rotate on the inner wall of the storage box 20 through the connecting shaft 40.

[0032] See Figure 5 The feeding assembly includes an opening / closing door 60 and a pressure block 61. The inner wall of the storage box 20 has an arc-shaped sliding groove. The opening / closing door 60 is slidably connected to the inner wall of the sliding groove on the storage box 20. Elastic elements for resetting are installed on the opposing walls of the opening / closing door 60 and the sliding groove. The pressure block 61 is fixedly connected to both ends of the opening / closing door 60, and the top of the pressure block 61 on the side away from the opening / closing door 60 is arc-shaped. Extrusion blocks 51 for squeezing and pushing the pressure block 61 are fixedly connected to both ends of the top of the partition plate 50. The extrusion blocks 51 rotate near the partition plate 50. The moving side is arc-shaped. When the partition plate 50 rotates to the bottom, the squeezing block 51 squeezes the pressure block 61, which drives the opening and closing door 60 to slide and unfold in the sliding groove. The object to be thrown on one side of the partition plate 50 can fall through the opening and be thrown. When the squeezing block 51 drives the pressure block 61 to the tail end, since the squeezing block 51 and the pressure block 61 are arc-shaped on one side, the contact surface on them is reduced. At this time, the squeezing stress cannot support the rotation of the opening and closing door 60, and the elastic element drives the opening and closing door 60 to reset and seal.

[0033] See Figure 6 and Figure 8The adjustment assembly includes a transmission rod 80 and an adjustment screw 83. The transmission rod 80 is rotatably connected to the inner wall of the connecting shaft 40 at its axial position. An adjustment plate 84 is slidably connected to the inner wall of the connecting shaft 40 at the bottom of the insertion slot 43. The adjustment screw 83 is rotatably connected to the inner wall of the connecting shaft 40 and threadedly connected to the inner wall of the adjustment plate 84. A plurality of linearly arranged first bevel gears 81 are fixedly connected to the outer wall of the transmission rod 80. A second bevel gear 82 that meshes with the first bevel gear 81 is fixedly connected to the adjustment screw 83 near the axial position of one end of the transmission rod 80. A connecting plate 85 is fixedly connected to the end of the adjustment plate 84 near the insertion slot 43. A knob 70 is installed on one end of the transmission rod 80. When the knob 70 is rotated, the first bevel gear 81 on the transmission rod 80 drives the second bevel gear 82 meshing with it to rotate. Then, the rotation of the adjustment screw 83 drives the adjustment plate 84 threadedly connected to it to slide.

[0034] The adjustment assembly also includes a push plate 94. A second sliding hole is provided at the end of the insertion cavity 44 away from the insertion slot 43. A connecting rod 91 is slidably connected to the inner wall of the second sliding hole. The push plate 94 is fixedly connected to one end of the connecting rod 91 and slidably connected to the inner wall of the insertion cavity 44. The connecting rod 91 is located on one side of the connecting plate 85. Specifically, an inclined pressure plate 90 is fixedly connected to the end of the connecting rod 91 away from the push plate 94. An inclined extrusion plate 86 is fixedly connected to the side of the connecting plate 85 near the pressure plate 90. The extrusion plate 86 is in contact with the pressure plate 90. A sliding disk 92 is fixedly connected to the outer wall of the connecting rod 91. A third spring 93 is fixedly connected to the wall surface opposite to the second sliding hole of the sliding disk 92. When the adjustment plate 84 moves, the pressure plate 90 can be extruded through the connecting plate 85 and the extrusion plate 86, thereby driving the connecting rod 91 to slide in the second sliding hole and driving the push plate 94 to slide in the insertion cavity 44.

[0035] For more details, please refer to Figure 6 A sliding rod 72 is installed on one side of the knob 70, and a sliding block 73 is fixedly connected to the end of the sliding rod 72. A third sliding hole is opened in the transmission rod 80, and a rectangular groove is opened at the end of the third sliding hole. The sliding rod 72 and the sliding block 73 are slidably connected to the inner wall of the third sliding hole and the rectangular groove, respectively. A limit hole is opened at one end of the connecting shaft 40, and a limit rod 71 that matches the limit hole is fixedly connected to one end of the knob 70. Specifically, when the knob 70 moves, the limit rod 71 can be pulled out from the limit hole to release the limitation on the rotation of the knob 70. Then the knob 70 can drive the transmission rod 80 to rotate through the sliding rod 72 and the sliding block 73. After the adjustment is completed, the limit rod 71 on the knob 70 is pressed into the limit groove. At this time, the sliding rod 72 and the sliding block 73 slide in the third sliding hole and the rectangular groove, thereby limiting the rotation of the knob 70 and preventing the knob 70 from deflecting when the connecting shaft 40 rotates, which would affect the stability of the partition plate 50 installation.

[0036] The working principle of this utility model is as follows: When installation is required, the knob 70 drives the transmission rod 80 to rotate, which in turn drives the adjustment plate 84 to move through the rotation of the first bevel gear 81, the second bevel gear 82, and the adjusting screw 83. The adjustment plate 84 drives the push plate 94 to slide in the insertion cavity 44 through the connecting plate 85, the pressing plate 86, the bearing plate 90, and the connecting rod 91. The push plate 94 is slid to the insertion cavity 44 near the insertion slot 43 for sealing. At this time, the mating strip 52 on the partition plate 50 is inserted into the installation strip 42. When the main insertion rod 54 is inserted into the insertion slot 43, the sealing of the push plate 94 prevents the auxiliary insertion rod from being inserted into the slot. When rod 55 is inserted into the insertion cavity 44, the main insertion rod 54 is pushed back into the adjusting seat 53 by the arc surface of the inner wall of the insertion cavity 44. When the connecting strip 52 is inserted to the end, the knob 70 is rotated in the opposite direction to move the push plate 94 away from the insertion slot 43. At this time, the main insertion rod 54 can be inserted into the insertion slot 43. The first spring 56 is inserted into the inner wall of the insertion cavity 44 by the elastic force of the second spring 57 to complete the fixation. When disassembly is required, simply rotate the knob 70 to push the push plate 94 to push the auxiliary insertion rod 55 back into the main insertion rod 54. Disassembly can then be carried out by moving the partition plate 50.

[0037] When throwing is required, first open the box door 21, place the object to be thrown between the two partition plates 50, and start the servo motor 31. The servo motor 31 will drive the second rotating plate 41 to rotate through the drive gear 34, driven gear 35, transmission shaft 36, first rotating plate 37 and pulley 38. Then, it will drive the partition plate 50 to rotate through the connecting shaft 40. When the partition plate 50 rotates to the bottom, the squeezing block 51 will squeeze the pressure block 61 to drive the opening and closing door 60 to slide open. The object to be thrown can then be fed through the opening. When the squeezing block 51 on the partition plate 50 moves to the tail end of the pressure block 61, the squeezing pressure will be reduced through the contact of the arc surfaces of the two. The pressure will not be able to support the rotation of the opening and closing door 60, and the elastic element will drive the opening and closing door 60 to reset, and then the throwing can be carried out in sequence.

[0038] When in use, the partition plate 50 can be easily installed and disassembled through the set connecting components and docking components, thereby dividing the space of the storage box 20. It can store multiple throwables without the need for the drone to turn back for loading, which would affect the throwing efficiency. Furthermore, the internal space of the storage box 20 can be adjusted according to the different positions in which the partition plate 50 is installed, making it convenient to store different throwables.

[0039] By using the feeding and driving components, the material can be thrown between the partition plates 50 sequentially by squeezing the pressure block 61, thereby enabling precise control of multiple throws and improving the accuracy of the throws.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
