Description

Technical Field

[0001] This invention relates to the field of multi-barrel grenade launcher technology, and more specifically to an ejection mechanism for a multi-barrel long-range launcher. Background Technology

[0002] For vehicle-mounted grenade launchers, there are generally two methods for ejection mechanisms. One method involves not having a dedicated ejection mechanism on the launcher, requiring manual removal using tools. The other method involves a dedicated ejection mechanism that manually ejects the spent cartridge case or unfired grenade from the chamber a certain distance, allowing for manual removal. This method solves the problem of difficulty in removing the cartridge case manually or using tools in the first method. To meet the operational requirements of rapid ejection and reloading, a synchronized ejection mechanism is generally installed on multi-shot launchers. For example, Chinese patent application number 202410028596.X discloses an ejection mechanism that uses an integrated ejection plate to push out the spent cartridge cases from each chamber. However, this method has drawbacks such as high manufacturing requirements, easy deformation of the plate, large mass, concentrated force application, inconvenient use, and inability to automatically eject cartridge cases.

[0003] If an ejection mechanism could automatically eject the spent cartridge case after the launcher is unlocked, manual operation would be unnecessary, significantly simplifying the ejection process and improving efficiency. Currently, there is no mechanism in existing multi-barrel launcher ejection technology capable of automatically ejecting spent cartridge cases.

[0004] In the design of a certain multi-barrel long-range grenade launcher, the launch tubes of the launcher adopt a 3-2-3 layout (i.e., a 3-2-3 layered layout from top to bottom, with the launch tubes in adjacent layers staggered). This innovative 3-2-3 staggered layout is employed from top to bottom. This tight arrangement results in extremely limited usable space between the launch tubes, thus increasing the complexity and challenge of the ejection mechanism design. Therefore, it is necessary to design a new ejection mechanism to handle the ejection operation of this novel layout design of the multi-barrel long-range grenade launcher. Summary of the Invention

[0005] In view of the deficiencies or improvement needs of the prior art, this application provides an ejection mechanism for a multi-barrel long-range launcher, which aims to solve the technical problem that there is no suitable ejection mechanism for multi-barrel long-range grenade launchers with a 323 layout of launch tubes in the prior art.

[0006] This application provides a shell ejection mechanism for a multi-tube remote transmitter, which is installed on the rear connection of the multi-tube remote transmitter and is used for shell ejection of a multi-tube remote transmitter with a 323 layout. The shell ejection mechanism includes a shell ejection seat, a guide, four shell ejection ejectors and at least one shell ejection drive. The ejector seat is movably disposed between two bullet holes in the middle layer. The ejector seat is disposed opposite to the rear link. The guide is used to guide the ejector seat to move closer to or away from the rear link. The ejector seat has four mounting arms arranged along its circumference. A clearance groove is formed between two adjacent mounting arms to avoid the bullet holes in the corresponding direction. The number of ejectors is 4 and they are respectively installed on the 4 mounting arms. Each ejector has 3 bullet holes evenly distributed on its outer side. The end of each ejector away from the ejector seat is movably inserted through the rear connector and is equipped with a top bullet tooth. Each top bullet tooth is configured to simultaneously eject the cartridge case from the 3 bullet holes on its outer side. The shell ejection drive is connected to the rear connector and is used to drive the shell ejection seat to move along the guide.

[0007] As a further preferred embodiment, the shell ejection drive includes a shell ejection handle and a handle support. One end of the handle support is fixed to the rear connector, and the shell ejection handle is hinged to the other end of the handle support to form a lever structure. The shell ejection handle has a force-receiving part and a force-applying part located on both sides of the handle support, and the force-applying part is connected to the shell ejection support.

[0008] As a further preferred embodiment, the shell removal handle is a U-shaped structure with two support arms. The handle support includes two parallel support rods arranged on the rear connector. The ends of the two support rods are hinged to the middle of the two support arms, and the ends of the two support arms respectively drive the two mounting arms.

[0009] As a further preferred embodiment, the support rod has a first limiting through hole, the support arm passes through the corresponding first limiting through hole, and the support rod is provided with a pin that passes through the support rod and the support arm.

[0010] As a further preferred embodiment, a limiting groove is formed on the mounting arm, and a second limiting through hole is formed on the ejector pin that communicates with the limiting groove. The end of the support arm extends into the limiting groove and is inserted into the corresponding second limiting through hole.

[0011] As a further preferred embodiment, the shell ejection mechanism further includes a transmitter hinged to the lower end of the rear link, the transmitter being horizontal to the rotation axis of the rear link, at least one of the shell ejection drive components being disposed on the lower side of the shell ejection support, and a drive protrusion being connected to the lower end of the transmitter, the drive protrusion pushing the force-receiving part located on the lower side of the shell ejection support when the transmitter rotates open relative to the rear link.

[0012] As a further preferred embodiment, the top spring tooth includes three top spring portions, and the three top spring portions correspond one-to-one with the three spring holes on the outer side of the ejector; the rear assembly is provided with an adapter groove on the outer side of each ejector that mates with the top spring tooth, and when the top spring tooth enters the adapter groove, at least a portion of the top spring portion extends into the corresponding spring hole.

[0013] As a further preferred embodiment, the guide member includes a guide rod, one end of which is fixed to the rear connector, and the ejector seat is movably sleeved on the other end of the guide rod, with the guide rod evenly distributed on the ejector seat.

[0014] As a further preferred embodiment, the shell ejection mechanism further includes an elastic reset member disposed between the shell ejection support and the rear connector, the elastic reset member being used to force the shell ejection support to move away from the rear connector.

Its four circumferential mounting arms form a clearance groove to avoid obstructing the bullet holes during movement. The four ejection ejectors are mounted on the mounting arms, and the top tooth of each ejection ejector can simultaneously eject the bullet casings from the three bullet holes. This design structure precisely corresponds to the special bullet hole layout of the rear section, making full use of the limited space under the 323 layout, and efficiently and accurately ejecting the bullet casings in each bullet hole, thus solving the ejection problem under a specific layout.

[0017] 2. The combined design of the U-shaped structure and support rod makes the shell ejection handle more stable and balanced, and can transmit force more evenly during operation, ensuring the smooth movement of the shell ejection seat.

[0018] 3.

[0024] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0025] like Figure 1 and Figure 2As shown, this application embodiment provides a shell ejection mechanism for a multi-barrel remote launcher, which is installed on the rear connector 100 of the multi-barrel remote launcher and is used for shell ejection of the multi-barrel remote launcher using a 323 layout. In the technical solution involved in this application, the 323 layout means that eight bullet holes 101 are formed on the rear connector 100. The eight bullet holes 101 are divided into three layers from top to bottom and are distributed in the manner of three, two and three respectively. The bullet holes 101 between adjacent layers are staggered.

[0026] The shell removal mechanism of this embodiment includes a shell removal support 10, a guide 20, four shell removal supports 30, and at least one shell removal drive 40.

[0027] The ejector seat 10 is movably disposed between two bullet holes 101 located in the middle layer. The ejector seat 10 is disposed opposite to the rear link 100. The guide member 20 is used to guide the ejector seat 10 to move closer to or away from the rear link 100. The ejector seat 10 is provided with four mounting arms 11 along its circumference. A clearance groove 11a is formed between two adjacent mounting arms 11 to avoid the bullet holes 101 in the corresponding direction. Since the bullet holes 101 are generally circular, the clearance groove 11a is preferably designed as an arc-shaped groove.

[0028] In this application, there are four ejector pins 30, which are respectively installed on four mounting arms 11. Each ejector pin 30 has three bullet holes 101 evenly distributed on its outer side. The end of each ejector pin 30 away from the ejector pin seat 10 is movably inserted into the rear connector 100 and is equipped with a top ejector tooth 31. Each top ejector tooth 31 is configured to simultaneously eject the cartridge case from the three bullet holes 101 on its outer side. In order to maintain symmetry and force stability, it is preferable that the installation positions of the four ejector pins 30 form the four vertices of a rectangle.

[0029] The ejector seat 10 is located between the two bullet holes in the middle layer and is opposite to the rear section. Its four circumferential mounting arms form a clearance groove 11a to avoid the bullet holes 101, ensuring that the bullet holes 101 are not affected during movement. The four ejectors 30 are respectively mounted on the mounting arms 11. The top tooth 31 of each ejector 30 can simultaneously eject the bullet casings in the three bullet holes 101. This design structure precisely corresponds to the special bullet hole layout of the rear section, making full use of the limited space under the 323 layout, and efficiently and accurately ejecting the bullet casings in each bullet hole 101, solving the ejection problem under the specific layout.

[0030] In this embodiment, the structure adopted by the ejector teeth 31 of each ejector 30 to simultaneously eject the cartridge cases from the three cartridge cases 101 is as follows: the ejector teeth 31 include three ejector portions 311, and the three ejector portions 311 correspond one-to-one with the three cartridge cases 101 on the outside of the ejector 30; the rear link 100 is provided with an adapter groove 102 on the outside of each ejector 30 to cooperate with the ejector teeth 31. When the ejector teeth 31 enter the adapter groove 102, at least a part of the ejector portion 311 extends into the corresponding cartridge case 101.

[0031] With the precise alignment of the three ejector parts 311 of the ejector tooth 31 with the bullet hole 101 and the cooperation of the adapter groove 102, the cartridge case can be ejected from the bullet hole more stably and effectively, improving the stability and reliability of ejection and ensuring that each cartridge case can be successfully ejected.

[0032] The shell ejection drive 40 is connected to the rear coupling 100 and is used to drive the shell ejection ejector 30 to move along the guide 20.

[0033] In the embodiments of this application, combined with Figure 3 As shown, the shell ejection drive 40 includes a shell ejection handle 41 and a handle support 42. One end of the handle support 42 is fixed to the rear connector 100, and the shell ejection handle 41 is hinged to the other end of the handle support 42 to form a lever structure. The shell ejection handle 41 has a force-receiving part 411 and a force-applying part 412 located on both sides of the handle support 42. The force-applying part 412 is connected to the shell ejection seat 10. By using the lever structure, the force-receiving position and the force-applying position are separated, thereby effectively solving the problem that the shell ejection seat 30 is installed in a narrow position and it is not easy to apply force, reducing the difficulty of operation for operators and improving the convenience and efficiency of operation.

[0034] The force-applying part 412 is connected to the shell ejector 10 so that the driving force acting on the force-receiving part 411 can be transmitted to the shell ejector 10. It can be understood that the force-applying part 412 can be directly connected to the main body structure of the shell ejector 10, or it can be connected to the mounting arm 11 on the shell ejector 10.

[0035] The shell ejection handle 41 has a U-shaped structure with two support arms 413. The handle support 42 includes two parallel support rods 421 on the rear connector 100. The ends of the two support rods 421 are hinged to the middle of the two support arms 413 respectively. The ends of the two support arms 413 respectively drive the two mounting arms 11. Through the cooperative design of the U-shaped structure and the support rods 421, the shell ejection handle 41 is more stable and balanced, and can transmit force more evenly during operation, ensuring the smooth movement of the shell ejection seat 10.

[0036] More preferably, a first limiting through hole 42a is formed on the support rod 421, and the support arm passes through the corresponding first limiting through hole 42a. A pin 43 is provided on the support rod 421 to pass through the support rod 421 and the support arm. Through the cooperation of the first limiting through hole 42a and the pin 43, the movement of the support arm 413 is precisely limited and guided, ensuring that the support arm 413 can only move within the specified trajectory, preventing the support arm 413 from deviating or swaying, thereby ensuring the accuracy and reliability of the overall movement.

[0037] A limiting groove 11b is formed on the mounting arm 11, and a second limiting through hole 30a communicating with the limiting groove 11b is formed on the ejector 30. The end of the support arm 413 extends into the limiting groove 11b and is inserted into the corresponding second limiting through hole 30a. Preferably, the end of the support arm 413 has a circular plate-like structure, which allows for better movement within the second limiting through hole 30a. Through the connection and cooperation of the limiting groove 11b, the second limiting hole 30a, and the support arm 413, the connection stability and motion coordination between the support arm 413 and the ejector 30 are enhanced, so that the movement of the support arm 413 can be accurately transmitted to the ejector 30, ensuring that the ejector 30 moves in the predetermined direction and stroke, thereby improving the accuracy of the ejection operation.

[0038] To achieve automatic shell ejection, the shell ejection mechanism also includes a transmitter 200 hinged to the lower end of the rear connector 100. The rotation axis of the transmitter 200 and the rear connector 100 are horizontal. At least one shell ejection drive 40 is disposed on the lower side of the shell ejection support 10. A drive protrusion 44 is connected to the lower end of the transmitter 200. When the transmitter 200 rotates and opens relative to the rear connector 100, the drive protrusion 44 pushes the force-receiving part 411 located on the lower side of the shell ejection support 10.

[0039] Combination Figure 4 As shown, when the transmitter 200 rotates and opens relative to the rear coupling 100, the drive protrusion 44 pushes the force application part 412 located on the lower side of the ejection seat 10, realizing the linkage between the transmitter 200 and the ejection mechanism. When the transmitter 200 rotates and opens in an electrically powered state (as shown in the image), the force application part 412 is pushed by the drive protrusion 44. Figure 4 (in the direction of arrow A), which can drive the drive protrusion 44 to swing (e.g. Figure 4 (in the direction of arrow B), thereby pushing the ejection handle 41 to swing, thereby moving the ejection seat 10 (as shown by arrow B). Figure 4 (In the direction of the arrow C), the top tooth 31 pushes the cartridge case out of the bullet hole 101 a certain distance, and then the cartridge case is manually removed. This process eliminates the need for manual pushing, realizes automatic ejection, improves the automation and efficiency of ejection, and meets the service requirements of rapid ejection and loading.

[0040] However, in practice, it has been found that relying solely on the automatic ejection mechanism has limitations in operational use. The necessity of manual ejection in special circumstances needs to be considered, giving the transmitter dual functionality of both manual and automatic ejection. Therefore, in the preferred embodiment of this application, multiple ejection drive units 40 can be provided. For example, one ejection drive unit 40 can be provided on both the upper and lower sides of the ejection holder 10. The ejection drive unit 40 on the lower side of the ejection holder 10 cooperates with the transmitter 200 to achieve automatic ejection, while the ejection drive unit 40 on the upper side is used for manual ejection. Specifically, when the force-receiving part 411 of the ejection handle 41 is pushed during use, the force-applying part 412 rotates the pin 43, causing the ejection holder 10 to move backward. The ejector tooth 31 pushes the cartridge case out of the cartridge hole 101 a certain distance, and then the cartridge case can be manually removed.

[0041] In this embodiment, the guide member 20 includes a guide rod 21. One end of the guide rod 21 is fixed to the rear connector 100, and the shell ejector seat 10 is movably sleeved on the other end of the guide rod 21. The guide rod 21 is evenly distributed on the shell ejector seat 10.

[0042] The shell ejection mechanism also includes a resilient reset element, which is disposed between the shell ejection support 10 and the rear connector 100. The resilient reset element is used to force the shell ejection support 10 to move away from the rear connector 100. After the shell ejection operation is completed, the resilient reset element can automatically reset the shell ejection support 10 to its initial position, preparing for the next shell ejection operation, improving the automation level and ease of use of the shell ejection mechanism, and reducing the workload of manual reset.

[0043] The elastic reset component includes a reset spring 50, which is fitted onto the guide rod 21 and its two ends abut against the ejector seat 10 and the rear connector 100, respectively, to ensure that the direction of the force of the reset spring is accurate and to effectively realize the reset function of the ejector seat.

[0044] In summary, the embodiments of this application provide an ejection mechanism adapted to the special 323 bullet hole layout of a multi-tube launcher, which achieves precise and efficient synchronous ejection of the cartridge case, makes efficient use of limited space, improves the degree of automation of ejection, enhances the convenience of operation, ensures a smooth and reliable ejection process, and effectively solves the ejection problem under complex layouts.
