Description

Technical Field

[0001] The present application belongs to the technical field of bird-repelling equipment, and specifically provides a bird-repelling cannon capable of firing bird-repelling bullets. Background Art

[0002] The problem of bird repelling at airports has always been a common problem that plagues the aviation industry in countries around the world. Since the movement is relative, the relative speed between the aircraft and the bird is extremely high. If the two collide, the aircraft will suffer a great impact force. Bird strikes may damage the aircraft's control surface, penetrate the aircraft skin or cockpit glass, and even damage the aircraft engine, seriously affecting aviation safety. Due to the influence of the flight altitude of birds, the take-off and landing process of aircraft is the most prone to bird strikes. More than 90% of bird strikes occur in the airspace near the airport and airport, and 50% occur in the airspace below 30 meters. Therefore, bird strikes have always posed a serious threat to the flight safety of aircraft.

[0003] Most of the existing mainstream bird-repellent equipment uses optical and acoustic principles to repel birds.

[0004] Bird-repelling devices that use the optical bird-repelling principle are mostly laser bird repellents. Since the laser beam emitted by the laser bird repellent is directionally propagated and the laser beam needs to illuminate the eyes of the flying bird to play a bird-repelling effect, the laser beam needs to be scanned over a large range to play a better bird-repelling effect. However, since laser beams also have a stimulating effect on the human eye, there is a possibility that the laser beam will illuminate the pilot's eyes and affect flight safety.

[0005] Due to the loud roar of aircraft engines during takeoff and landing, birds near airports gradually adapt to loud sounds over time. Driving away birds simply by making loud sounds is not effective, so launching bird-repelling bombs and using the light and sound of sufficient intensity produced by the bombs exploding in the air has become the best option for airports.

[0006] The use of traditional bird-repellent bombs can be divided into two stages: the first stage is the launch stage, and the second stage is the explosion stage. The launch of traditional bird-repellent bombs is achieved by igniting the propellant powder through a fuse, and the launch of the bird-repellent bomb is achieved by burning the gas generated by the propellant powder. With the advancement of science and technology, the launch method of launching bird-repellent bombs by igniting the propellant powder has gradually begun to be replaced. In order to achieve a better bird-repelling effect, the launch of bird-repellent bombs has gradually tended to be automated. Bird-repellent bombs are launched into the air through bird-repellent guns that can automatically adjust the direction, angle and other factors according to the location of the bird flock. The bird-repellent guns automatically monitor and automatically integrate data to determine the launch factors, as well as control the deployment of the machine. The method of jointly networking multiple bird-repelling guns at the airport can realize automatic bird-repelling at the airport. Compared with manual operation, the bird-repelling gun has higher bird-repelling efficiency and faster response. However, the bird-repelling gun needs to be reloaded with bird-repelling bullets after firing. In order to realize the automatic loading of bird-repelling bullets, an automatic loading mechanism that can cooperate with the bullet storage device to load the bird-repelling bullets is needed. Since the cartridge of the bird-repelling bullet is large, the loading of the bird-repelling bullet is difficult, and the bird-repelling bullet is prone to jamming during the loading process, thereby affecting the firing of the bird-repelling bullet and the bird-repelling effect of the bird-repelling gun. Summary of the invention

[0007] In order to solve the problem of automated loading of bird-repellent bullets, avoid jamming of the bird-repellent bullets during loading, and avoid squeezing of the bird-repellent bullets by the loading device, the present application provides a bird-repellent gun.

[0008] A bird-repelling cannon is capable of firing bird-repelling bullets. The cannon comprises a bullet storage portion with a bullet storage cavity inside, the bullet storage cavity can store the bird-repelling bullets, the bullet storage portion is also provided with a bullet outlet connected to the bullet storage cavity, the bullet storage cavity can guide the bird-repelling bullets to leave the bullet storage cavity in sequence through the bullet outlet under the action of gravity; a bullet feeding turntable is rotatably arranged below the bullet outlet, the bullet feeding turntable is provided with a bullet feeding channel running through its two rotating end faces, during the rotation process, one rotating end face of the bullet feeding turntable can block the bullet outlet until the bullet feeding channel is aligned with the bullet outlet to receive the bird-repelling bullet, and the bullet feeding channel can deliver the bird-repelling bullet to a bullet feeding position along its rotating path; a guide member is arranged below the bullet feeding turntable The guide piece is provided with a guide hole running through it, the guide hole can be aligned with the bullet feeding channel connected to the bullet feeding position, and the guide piece can block the bullet feeding channel away from the bullet feeding position in the vertical direction; a transfer piece is provided with a bullet filling hole, which is arranged below the guide piece, and the transfer piece can rotate around a fixed axis so that the bullet filling hole can switch between the bullet receiving position and the bullet loading position, and the bullet filling hole at the bullet receiving position can be aligned with the guide hole; the bullet filling piece can move linearly from the initial position to the bullet filling position, and during the movement, the bullet filling piece can pass through the bullet filling hole at the bullet loading position to push out the bird-repelling bullet in the bullet filling hole until it reaches the bullet filling position.

[0009] A rotating end surface of the bullet feeding turntable can block the bullet outlet to prevent the bird-repelling bullets in the bullet storage cavity from entering the outside through the bullet outlet. Until the bullet feeding channel of the bullet feeding turntable rotates to the bottom of the bullet outlet and aligns with the bullet outlet, the rotating end surface can no longer block the bullet outlet due to the existence of the bullet feeding channel. Therefore, the bird-repelling bullet can move regularly and spontaneously under the guidance of the bullet storage cavity and the action of gravity, and can leave the bullet storage cavity through the bullet outlet in turn and fall into the bullet feeding channel aligned with the bullet outlet. Since the guide hole and the bullet feeding channel are not opposite to and connected with each other at this time, the guide member arranged under the bullet feeding turntable can block the side of the bullet feeding channel away from the bullet outlet when the bird-repelling bullet falls into the feeding channel. The guide member provides a force to enable the bird-repelling bullet to overcome its own gravity, thereby The bird-repellent bullet stops falling and remains in the bullet feeding channel; the bullet feeding turntable can drive the bird-repellent bullet to move through the bullet feeding channel until the bullet feeding channel moves to the bullet feeding position and is aligned with the guide hole on the guide member, the guide member can no longer block the bullet feeding channel, and the bird-repellent bullet in the bullet feeding channel spontaneously falls into the bullet filling hole located at the bullet receiving position through the guide hole under the action of gravity, thereby realizing bullet retrieval, the transport member can rotate around a fixed axis, and the bullet filling hole can switch between the bullet receiving position and the bullet loading position, so that the bullet filling hole located at the bullet receiving position can carry the bird-repellent bullet to the bullet loading position, and after the bird-repellent bullet follows the bullet filling hole to move to the bullet loading position, the bullet filling member passes through the bullet filling hole and pushes out the bird-repellent bullet in the bullet filling hole until it reaches the bullet loading position, thereby completing the loading of the bird-repellent bullet. The bird-repelling cannon only needs to utilize the guiding function of the bullet storage chamber, the rotational movement of the bullet feeding turntable, the shielding effect of the guide on the bullet feeding turntable, and the gravity of the bird-repelling bullet to achieve orderly and controllable bullet removal. The bullet removal mechanism is simple and reliable, thus avoiding the use of a complex bullet removal mechanism to increase the risk of jamming. The guide can block the bullet feeding channel until the bullet feeding channel moves to the bullet feeding position, and the bird-repelling bullet can fall into the bullet filling hole on the transport part, thereby achieving the orderly falling and orderly loading of the bird-repelling bullets in the bullet feeding channel, and the controllable falling position. The structure is simple but reliable, and effectively reduces the risk of jamming. Through the simple linear movement of the bullet filling part, the bird-repelling bullet can be pushed to the bullet filling position to complete the bullet filling. By utilizing the guiding effect of the bullet storage cavity, the self-gravity of the bird-repellent bullet, the rotational movement of the bullet-feeding turntable, the shielding effect of the guide member, and controlling the timing of the bird-repellent bullet leaving the bullet-feeding channel through the guide hole, the rotation of the transfer member, and the linear movement of the bullet-filling member, accurate bullet retrieval, orderly bullet retrieval, and accurate loading can be achieved. At the same time, since the bird-repellent bullet utilizes its own gravity to pass through the bullet outlet, the bullet-feeding channel, the guide hole, and the bullet-filling hole in sequence, the loading of the bird-repellent bullet is achieved. The structure is simple and reliable, and the bird-repellent bullet will not be squeezed during the loading process, thereby improving the safety of loading.

[0010] In one embodiment of the present application, the bullet feeding turntable is provided with at least two bullet feeding channels, and the at least two bullet feeding channels are arranged at intervals along the rotation path of the bullet feeding turntable.

[0011] By providing at least two bullet feeding channels, when the bullet feeding turntable rotates continuously, the interval time between the bird-repelling bullets falling into the bullet feeding channels and the bird-repelling bullets in the bullet feeding channels falling into the guide holes can be greatly reduced, thereby improving the bullet retrieval efficiency.

[0012] In one embodiment of the present application, the bird-scaring gun is provided with a plurality of bullet storage parts, and the bullet feeding channel of the bullet feeding turntable can be respectively aligned with the bullet outlet of each bullet storage part on its rotation path.

[0013] In the present application, multiple bullet storage sections are set up, and the bullet feeding channel of the bullet feeding turntable can be respectively aligned with the bullet outlet of each bullet storage section on its rotation path. The multiple bullet storage sections need to be arranged in a ring shape to be able to be arranged in a rotating manner with the bullet feeding channel. The ring shape arrangement can significantly reduce the size of the space occupied by the bullet storage sections. At the same time, the multiple bullet storage sections can significantly increase the storage capacity and reduce the number of times the bullet storage sections are refilled.

[0014] In one embodiment of the present application, a guide groove is provided on the rotating end surface of the bullet feeding turntable opposite to the bullet outlet, the guide groove extends along its rotation direction, and has a starting end and an ending end relatively arranged, the starting end points in the direction of the ending end, the groove depth of the guide groove gradually decreases until the groove bottom of the ending end extends to the rotating end surface, and the bullet feeding channel is opened at the groove bottom of the starting end.

[0015] By providing the guide groove, it is possible to avoid a situation in which a bird-repellent bullet is simultaneously in the bullet storage chamber and the bullet feeding channel during the rotation of the bullet feeding turntable, thereby preventing the bullet from getting stuck.

[0016] In one embodiment of the present application, the bullet filling hole is a stepped hole.

[0017] In one embodiment of the present application, the bird-repelling cannon is also provided with a launching tube having a launching chamber, the launching tube is provided with a bullet feed port connected to the launching chamber, and when the transport component is located at the bullet loading position, the bullet loading hole is aligned with the bullet feed port; the transport component is also provided with a sealing portion; when the bullet loading hole leaves the bullet receiving position, the sealing portion can cover the guide hole; when the bullet loading hole leaves the bullet loading position, the sealing portion can close the bullet feed port.

[0018] When the bullet-loading hole leaves the bullet-receiving position, the sealing part can cover the guide hole, thereby preventing the ammunition in the bullet-feeding channel from falling to the outside through the guide hole and causing a jam. When the bullet-loading hole leaves the bullet-loading position, the sealing part can close the bullet-feeding port, thereby preventing the launch tube from leaking when the gas-type bird-repellent projectile is launched by pneumatic launch or when the gas-type bird-repellent projectile is launched by the combustion of gunpowder.

[0019] In one embodiment of the present application, the transfer member is provided with at least two bullet filling holes, which are spaced apart along the rotation direction of the transfer member, and a sealing portion is provided between adjacent bullet filling holes.

[0020] By providing at least two bullet-loading holes on the transfer member, which are spaced apart along the rotation direction of the transfer member, and providing a sealing portion between adjacent bullet-loading holes, the transfer member can carry a plurality of bird-repellent bullets at the same time. After the bird-repellent bullet in one bullet-loading hole enters the launch tube through the ejection action of the bullet-loading member, the transfer member rotates, and the adjacent sealing portion can close the bullet feed port to meet the launch requirements. After the launch is completed, the next bullet-loading hole along the rotation direction of the transfer member can be quickly moved to the bullet-loading position, thereby reducing the bullet-loading time and improving the loading efficiency.

[0021] In one embodiment of the present application, the filling piece can return from the filling position to the initial position and output a start signal; the bird-repelling cannon also includes a monitoring unit and a control unit, and the monitoring unit outputs a filling signal when it detects that the filling hole located at the bullet receiving position has a bird-repelling bullet; after receiving the filling signal and the start signal at the same time, the control unit can output a control signal to control the rotation of the transport piece so that the filling hole moves to the loading position.

[0059] In order to have a clearer understanding of the technical features, purposes and effects of the present application, the specific implementation methods of the present application are now described with reference to the accompanying drawings. The same reference numerals in the drawings represent components with the same structure or similar structures but the same functions.

[0060] In this document, “exemplary” means “serving as an example, instance or illustration”, and any diagram or implementation described in this document as “exemplary” should not be interpreted as a more preferred or more advantageous technical solution.

[0061] In order to simplify the drawings, only the parts related to the present application are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked.

[0062] In order to realize the automatic firing of the bird-repelling bomb 600, the bird-repelling gun needs to be provided with a bullet storage device and a bullet retrieval and loading device and other components.

[0063] The bird-repelling gun can fire 600 bird-repelling bullets. Figure 1 A structural stereogram of a schematic implementation of a partial structure of a bird-repelling cannon, see Figure 1 , which includes a bullet storage unit 101 (see Figure 3 ), the bullet feeding turntable 201, the guide part 301, the transfer part 401 and the bullet filling part 500.

[0064] See also Figure 4A bullet storage chamber 102 is provided inside the bullet storage portion 101, and the bullet storage chamber 102 can store the bird-repelling bullet 600. The shape of the bullet storage chamber 102 is cylindrical. When the bird-repelling bullet 600 is placed in the bullet storage chamber 102, the axial direction of the bird-repelling bullet 600 is the same as the axial direction of the bullet storage chamber 102. The diameter of the bullet storage chamber 102 is slightly larger than the bird-repelling bullet 600, so that the two ends of the bird-repelling bullet 600 can be prevented from flipping when the bird-repelling bullet 600 is placed in the bullet storage chamber 102. The bullet storage portion 101 is also provided with a bullet outlet connected to the bullet storage chamber 102. The bullet storage chamber 102 is vertically arranged or inclined, and the bullet storage chamber 102 can guide the bird-repelling bullets 600 to leave the bullet storage chamber 102 in sequence through the bullet outlet under the action of gravity. Of course, technicians in the technical field to which the present application belongs can understand that in order to achieve the sequential falling of the bird-repellent bombs 600 relying on their own gravity, the setting form of the bullet storage chamber 102 in the present application can also have other forms, such as forming the bullet storage chamber 102 by two arc-shaped plates, which can store the bird-repellent bombs 600 while also achieving the sequential falling of the bird-repellent bombs 600.

[0065] See also Figure 1 , Figure 2 , Figure 3 The bullet feeding turntable 201 is rotatably arranged below the bullet outlet. The bullet feeding turntable 201 is provided with a bullet feeding channel 202 that runs through its two rotating end faces. During the rotation process, one rotating end face of the bullet feeding turntable 201 can block the bullet outlet until the bullet feeding channel 202 is aligned with the bullet outlet to receive the bird-repelling bullet 600. The bullet feeding channel 202 can deliver the bird-repelling bullet 600 to a bullet feeding position along its rotation path. The shape of the bullet feeding turntable 201 is not limited to the shape of the disc shown in the figure, but can also be other shapes, such as a square disc.

[0066] See also Figure 1 , Figure 2 , Figure 3 , the guide member 301 is arranged below the bullet feeding turntable 201, and the guide member 301 is provided with a guide hole 302 running through it, and the guide hole 302 can be aligned with the bullet feeding channel 202 located at the bullet feeding position, and the guide member 301 can block the bullet feeding channel 202 away from the bullet feeding position in the vertical direction. The distance relationship between the bullet feeding turntable 201 and the guide member 301 is not limited to the fitting relationship shown in the figure, but can also be other distance relationships, such as a certain distance between the two, the guide member 301 can block the bullet feeding channel 202 to prevent the bird-repelling bullet 600 in the bullet feeding channel 202 from escaping from the bullet feeding channel 202, and the guide member 301 can receive the bird-repelling bullet 600 and avoid jamming.

[0067] See also Figure 1 , Figure 2 , Figure 3The transport member 401 is provided with a bullet filling hole 402, which is arranged below the guide member 301. The transport member 401 can rotate around a fixed axis so that the bullet filling hole 402 can switch between a bullet receiving position and a bullet loading position. The bullet filling hole 402 at the bullet receiving position can be aligned with the guide hole 302.

[0068] The bullet-filling member 500 can move linearly from the initial position to the bullet-filling position. During the movement, the bullet-filling member 500 can pass through the bullet-filling hole 402 at the loading position to push out the bird-repelling bullet 600 in the bullet-filling hole 402 until it reaches the bullet-filling position.

[0069] Those skilled in the art of the present application can understand that the bullet feeding turntable 201, the transfer member 401, and the bullet filling member 500 can be driven by a driving device such as a motor to move (see Figure 3 ).

[0070] The following is a brief description of the process of loading the bird repellent bomb 600, see Figure 4 A rotating end surface of the bullet feeding turntable 201 can cover the bullet outlet to prevent the bird repellent bullet 600 in the bullet storage cavity 102 from entering the outside through the bullet outlet, until the bullet feeding channel 202 of the bullet feeding turntable 201 rotates to the bottom of the bullet outlet and aligns with the bullet outlet, see Figure 5 , the rotating end surface cannot continue to block the bullet outlet due to the existence of the bullet feeding channel 202, so that the bird-repelling bullet 600 can spontaneously move toward the bullet inlet 703 under the guidance of the bullet storage chamber 102 and the action of gravity, and can leave the bullet storage chamber 102 through the bullet outlet in sequence and fall into the bullet feeding channel 202. Since the guide hole 302 on the guide member 301 is not opposite to the bullet outlet, the guide member 301 arranged below the bullet feeding turntable 201 can block the side of the bullet feeding channel 202 away from the bullet outlet when the bird-repelling bullet 600 falls into the delivery channel. The guide member 301 provides a force to enable the bird-repelling bullet 600 to overcome its own gravity, so that the bird-repelling bullet 600 stops falling and remains in the bullet feeding channel 202. The bullet feeding turntable 201 can drive the bird-repelling bullet 600 to move through the bullet feeding channel 202 until the bullet feeding channel 202 moves to the bullet feeding position and is aligned with the guide hole 302 on the guide member 301. Figure 6 , Figure 7, the guide member 301 can no longer block the bullet feeding channel 202, and the bird-repelling bullet 600 in the bullet feeding channel 202 spontaneously falls into the bullet-loading hole 402 located at the bullet receiving position through the guide hole 302 under the action of gravity. The bullet-loading hole 402 is a stepped hole, so that after the bird-repelling bullet 600 falls into the bullet-loading hole 402, the bullet-loading hole 402 can prevent the bird-repelling bullet 600 from continuing to fall and can carry the bird-repelling bullet 600. When the bird-repelling bullet 600 completely falls into the bullet-loading hole 402 and leaves the guide hole 302, the transport member 401 rotates, and the bullet-loading hole 402 can switch between the bullet-receiving position and the bullet-loading position, so that the bullet-loading hole 402 located at the bullet-receiving position can carry the bird-repelling bullet 600 to the bullet-loading position (see Figure 8 ), after the bird repellent bullet 600 moves to the loading position following the bullet filling hole 402, the bullet filling member 500 located at the initial position moves toward the bullet filling position to approach the bird repellent bullet 600 in the bullet filling hole 402, and passes through the bullet filling hole 402 to push out the bird repellent bullet 600 in the bullet filling hole 402 until the bird repellent bullet 600 reaches the bullet filling position (see Figure 8 , Fig. 9 , Fig.10 ).

[0071] Those skilled in the art of the present application can understand that the shape of the bullet filling hole 402 in the present application is not limited to the form of a stepped hole, and can also be other forms, such as the bullet filling hole 402 is a through hole with a constant diameter, a blocking member is provided below the bullet filling hole 402 to prevent the bird repellent bullet 600 from leaking out of the bullet filling hole 402, and the blocking member is provided with a channel for the bullet filling hole 402 to pass through, so that the bullet filling member 500 can push out the bird repellent bullet 600 in the bullet filling hole 402, or the bullet filling hole 402 is not formed. The hole 402 is a through hole with a constant diameter. A retaining spring is provided in the bullet-filling hole 402. After the bird-repellent bullet 600 enters the bullet-filling hole 402, the retaining spring can abut against the cartridge wall of the bird-repellent bullet 600 to prevent the bird-repellent bullet 600 from falling. A gap is left between the inner wall of the bullet-filling hole 402 and the retaining spring for the filling piece 500 to pass through, so that the filling piece 500 can pass through the bullet-filling hole 402 and push out the bird-repellent bullet 600. There are other ways to set the bullet-filling hole 402, which will not be repeated here.

[0072] The bird-repelling cannon using the above-mentioned structure can realize sequential loading by utilizing the gravity of the bird-repelling bullet 600 itself. The structure is simple and does not require a complicated transmission system. It only needs to utilize the rotational movement of the bullet feeding turntable 201, the shielding effect of the guide member 301 on the bullet feeding turntable 201, the guiding effect of the bullet storage chamber 102 and the gravity of the bird-repelling bullet 600 itself to realize orderly and controllable bullet removal. The bullet removal mechanism is simple and reliable, thereby avoiding the risk of increasing the jam by using a complicated bullet removal mechanism. The structure is simple but reliable, and the risk of jam is effectively reduced. The bird-repelling bullet 600 at the bullet receiving position can be delivered to the bullet loading position by the rotation of the transport member 401. The bird-repelling bullet 600 at the bullet loading position can be pushed to the bullet loading position by the simple linear movement of the bullet loading member 500 and the guiding effect of the bullet loading hole 402 to complete the bullet loading. The structure is simple but efficient, and the risk of jamming caused by complicated bullet loading actions can be avoided. By utilizing the guiding effect of the bullet storage chamber 102, the self-gravity of the bird-repelling bullet 600, the rotational movement of the bullet-feeding turntable 201, the shielding effect of the guide member 301, the rotation of the transport member 401, and the linear movement of the bullet-filling member 500, it is possible to achieve accurate bullet retrieval, orderly bullet retrieval, and accurate loading. At the same time, since the bird-repelling bullet 600 can sequentially pass through the bullet outlet, the bullet-feeding channel 202, the guide hole 302, and the bullet-filling hole 402 by utilizing its own gravity, the loading of the bird-repelling bullet 600 is realized. The structure is simple and reliable, and the bird-repelling bullet 600 will not be squeezed during the loading process, so that the bird-repelling bullet 600 is prevented from being squeezed, thereby improving the safety of loading. In the whole process, only the bullet-feeding turntable 201 and the transport member 401 that perform the rotational action, and the bullet-filling member 500 that performs the linear motion, need to move, the movement action is simple, and the three components can realize bullet retrieval, bullet transportation, and bullet loading by completing one movement action respectively, without the need for flipping and other movement actions, the process is orderly and simple, thereby reducing the risk of jamming.

[0073] See also Figure 1 , Fig.12 , Fig.13 , Fig.14 In one embodiment of the present application, a guide groove 203 is provided on the rotating end surface of the bullet feeding turntable 201 opposite to the bullet outlet, and the guide groove 203 extends along its rotation direction and has a starting end 204 and an ending end 205 that are relatively arranged, and the starting end 204 points in the direction of the ending end 205. The groove depth of the guide groove 203 gradually decreases until the groove bottom of the ending end 205 extends to the rotating end surface, and the bullet feeding channel 202 is opened at the groove bottom of the starting end 204.

[0074] See also Figure 1 , the bullet feeding turntable 201 rotates counterclockwise, so that the bullet outlet and the bullet feeding channel 202 move relative to each other, and the bullet outlet moves rightward relative to the bullet feeding channel 202 (see Fig.12), the bird-repelling bullet 600 at the bullet outlet slides on the rotating end surface of the bullet feeding turntable 201 until the bullet feeding channel 202 is aligned with the bullet outlet, and the bird-repelling bullet 600 at the bullet outlet falls into the bullet feeding channel 202, and the bird-repelling bullet 600 above it will fall with it. If the entry depth (the maximum value of the sum of the depth of the bullet feeding channel 202 and the distance between the bullet feeding turntable 201 and the guide member 301) is much smaller than the height of the bird-repelling bullet 600, one end of the bird-repelling bullet 600 will remain in the bullet storage cavity 102, while the other end has entered the bullet feeding channel 202, and the bullet outlet and the bullet feeding channel 202 move relative to each other, resulting in a jam; if the entry depth is greater than the height of the bird-repelling bullet 600, after the bird-repelling bullet 600 at the bottom enters the bullet feeding channel 202, the part of the bird-repelling bullet 600 above it located in the bullet storage cavity 102 will extend into the bullet feeding channel 202, causing a jam. By providing the guide groove 203, the matching requirements of the height and the entry depth of the bird-repelling bullet 600 can be reduced, and the production accuracy requirements of the bird-repelling bullet 600 can be reduced, so that the entry depth can be not less than the height of the bird-repelling bullet 600. When the bird-repelling bullet 600 completely enters the bullet-feeding channel 202 and its lower end abuts against the guide member 301, its upper end is slightly higher than the groove bottom of the starting end 204, so that when the bird-repelling bullet 600 enters the bullet-feeding channel 202 and one end contacts the guide member 301, the bullet storage chamber 102 located above the bullet 600 is slightly higher than the starting end 204. When one end of the bird-repelling bullet 600 enters the bullet-feeding channel 202, one end of the upper bird-repelling bullet 600 can contact the bottom of the guide groove 203 as the bullet-feeding turntable 201 rotates. Since the guide groove 203 extends along its rotation direction and the starting end 204 points to the direction of the end end 205, the depth of the guide groove 203 gradually decreases, and the bottom of the end end 205 extends to the rotating end face, so that the upper bird-repelling bullet 600 re-enters the bullet storage chamber 102 due to the change of the bottom of the groove, avoiding the occurrence of jamming. Fig.12 , Fig.13 , Fig.14 , the upper bird-repelling bullet 600 moves rightward relative to the bullet-feeding channel 202, and the upper end of the lower bird-repelling bullet 600 is higher than the groove bottom of the starting end 204. When the upper bird-repelling bullet 600 has not left the bullet-feeding channel 202, the lower bird-repelling bullet 600 will lift the upper bird-repelling bullet 600, so that the lower end of the upper bird-repelling bullet 600 will contact the groove bottom as the bullet-feeding turntable 201 rotates, and because the starting end 204 points to the direction of the ending end 205, the groove depth of the guide groove 203 gradually decreases, and the groove bottom of the ending end 205 extends to the rotating end surface, so that the lower end of the upper bird-repelling bullet 600 finally returns to the rotating end surface (see Fig.14 ), thereby preventing the side wall of the bird-repelling bullet 600 from contacting the inner wall of the bullet feeding channel 202 and causing a jam.

[0075] Those skilled in the art of the present application will understand that the shape of the bottom of the guide groove 203 in the present application is not only Figure 1 The flat bottom groove shown in the figure may also be in other forms, such as a U-shaped groove. The groove depth is the distance between the lower end of the bird-repelling bullet 600 and the rotating end surface above the bullet feeding turntable 201 when the bird-repelling bullet 600 contacts the guide groove 203 during transportation, so that the bird-repelling bullet 600 can return to the rotating end surface through the groove depth change of the guide groove 203.

[0076] Those skilled in the art of the present application can understand that the extending direction of the guide groove 203 in the present application is related to the rotation direction, and the extending direction of the guide groove 203 is not limited to Figure 1 The extending direction shown in the figure may also be other extending directions, which will not be described in detail here.

[0077] See also Figure 1 , Figure 3 , Figure 4 In one embodiment of the present application, the bird-repelling gun is provided with a plurality of bullet storage parts 101, each bullet storage part 101 is provided with a bullet storage cavity 102 and a bullet outlet communicated with the bullet storage cavity 102, and the bullet feeding channel 202 of the bullet feeding turntable 201 can be respectively aligned with the bullet outlet of each bullet storage part 101 on its rotation path. The bullet feeding turntable 201 is provided with at least two bullet feeding channels 202, and the at least two bullet feeding channels 202 are arranged at intervals along the rotation path of the bullet feeding turntable 201.

[0078] By setting a plurality of bullet storage parts 101, the bullet feeding channel 202 of the bullet feeding turntable 201 can be respectively aligned with the bullet outlet of each bullet storage part 101 on its rotation path. The plurality of bullet storage parts 101 need to be arranged in an annular manner to be arranged in accordance with the rotational motion of the bullet feeding channel 202. The annular arrangement of the plurality of bullet storage parts 101 can significantly reduce the size of the space occupied by the bullet storage parts 101. At the same time, the plurality of bullet storage parts 101 can significantly increase the amount of bullet storage and reduce the number of loading times. By setting at least two bullet feeding channels 202, the time interval between the bird-repelling bullet 600 falling from the bullet outlet into the bullet feeding channel 202 and the bird-repelling bullet 600 falling from the bullet feeding channel 202 into the guide hole 302 can be greatly reduced when the bullet feeding turntable 201 rotates continuously, thereby improving the bullet retrieval efficiency.

[0079] Of course, technicians in the technical field to which the present application belongs can understand that the arrangement of the bullet storage part 101 and the bullet storage cavity 102 in the present application is not limited to the arrangement described above, and the arrangement of the bullet storage part 101 and the bullet storage cavity 102 may also have other arrangement forms, such as the bullet storage part 101 may have only one, and one bullet storage part 101 may have multiple bullet storage cavities 102, and each bullet storage cavity 102 is respectively provided with a bullet outlet, which will not be repeated here.

[0080] In one embodiment of the present application, the bird-repelling gun is further provided with a launch tube 701 having a launch chamber 702, and the launch tube 701 is provided with a bullet feed port 703 connected to the launch chamber 702. When the transport member 401 is located at the bullet loading position, the bullet loading hole 402 is aligned with the bullet feed port 703 (see Figure 3 , Figure 8 ), the bullet-filling member 500 can push the bird-repelling bullet 600 out of the bullet-filling hole 402, and the bird-repelling bullet 600 enters the launch chamber 702 in the launch tube 701 through the bullet-feeding port 703 until it reaches the loading position (see Fig. 9 , Fig.10 ); When the launch of the bird-repelling bomb 600 requires the use of compressed gas to push the bird-repelling bomb 600 into the air or the ignition of the launching gunpowder of the bird-repelling bomb 600 to generate a large amount of gas to push the bird-repelling bomb 600 into the air, one end of the launch tube 701 needs to be sealed, and the transport member 401 is also provided with a sealing portion 404, see Fig.11 After the filling piece 500 pushes the bird-repelling bullet 600 into the firing chamber 702, a retaining spring capable of abutting against the bird-repelling bullet 600 is provided in the firing chamber 702, so that the retaining spring can retain the bird-repelling bullet 600 moved to the loading position in the firing chamber 702. At this time, the filling piece 500 returns to the initial position. After the filling piece 500 leaves the loading hole 402, the transporting piece 401 rotates, and after the loading hole 402 leaves the loading position, the sealing part 404 can close the bullet inlet 703, so as to seal one end of the firing chamber 702, thereby ensuring the airtightness of one end of the firing chamber 702, so as to achieve a better firing effect (see Fig.11 ); When the bullet filling hole 402 leaves the bullet receiving position, the sealing portion 404 can cover the guide hole 302, thereby preventing the bird-repelling bullet 600 from falling through the guide hole 302 to the bottom of the guide member 301, thereby preventing the falling bird-repelling bullet 600 from causing a jam and affecting the normal operation of the bird-repelling gun.

[0081] Further, in one embodiment of the present application, the transport member 401 is provided with at least two bullet-filling holes 402, which are arranged at intervals along the rotation direction of the transport member 401, and a sealing portion 404 is provided between adjacent bullet-filling holes 402 (see Fig.15 ).

[0082] By providing at least two bullet-loading holes 402 on the transfer member 401, which are spaced apart along the rotation direction of the transfer member 401, and providing a sealing portion 404 between adjacent bullet-loading holes 402, the transfer member 401 can carry a plurality of bird-repelling bullets 600 at the same time. After the bird-repelling bullet 600 in one bullet-loading hole 402 enters the launch tube 701 through the ejection action of the bullet-loading member 500, the transfer member 401 rotates, and the adjacent sealing portion 404 can close the bullet feed port 703 to meet the launch requirements. After the launch is completed, the next bullet-loading hole 402 along the rotation direction of the transfer member 401 can be quickly moved to the bullet-loading position, and the bird-repelling bullet 600 in the bullet-loading hole 402 can enter the launch chamber 702 after the ejection action of the bullet-loading member 500, thereby reducing the bullet-loading time and improving the loading efficiency.

[0083] See also Figure 3 In one embodiment of the present application, the bird-repelling gun is provided with a filling piece position sensor 501, which can sense the position of the filling piece 500. The filling piece position sensor 501 can be a photoelectric sensor, a magnetic position sensor or other sensors to determine whether the filling piece 500 is in the initial position or the filling position. When the filling piece 500 returns from the filling position to the initial position, the filling piece position sensor 501 will output a start signal to the controller 800. When the filling piece 500 is in the filling position, it will pass through the filling hole 402. Through the start signal, it can be avoided that when the filling piece 500 is in the filling position, the transport part 401 rotates, causing the filling hole 402 to collide with the filling piece 500, and at the same time, it can be avoided that the filling hole 402 rotates from the receiving position to the loading position. When the loading hole 402 at the bullet receiving position is detected, a loading signal is output to the controller 800. After receiving the loading signal and the start signal, the controller 800 can output a control signal to the driving device connected to the transport component 401 to control the rotation of the transport component 401 so that the loading hole 402 moves to the loading position.
