Abstract
Description
Technical Field
[0001] This application relates to the field of shell handling technology, specifically to a guiding device for ejecting shell casings from armored vehicles. Background Technology
[0002] When heavy weapons, such as the artillery of infantry fighting vehicles, are fired, the spent shell casings are ejected from the turret ejection port. However, due to poor ejection force, direction, and angle, the casings may not be ejected outside the vehicle and tend to accumulate above the troop compartment. Personnel need to climb onto the roof to collect them. Furthermore, when the turret rotates, the casings that fall onto the hull can easily get stuck between the turret and the hull, affecting the turret's rotation and firing. In severe cases, this can damage the motor and adversely affect combat operations. Utility Model Content
[0003] This application provides a guiding device for shell ejection from tanks, which can solve the problem in the prior art that when a tank's gun fires, the shell casings ejected from the turret ejection window cannot be ejected from the tank and will fall onto the tank.
[0004] This application provides a guiding device for ejecting spent shells from tank shells, comprising: A guide plate is installed at the bottom of the turret ejection port and is inclined at an angle to the top surface of the vehicle. The guide plate is provided with a guide part for changing the ejection trajectory of the shell casing and guiding the ejected shell casing to the outside of the vehicle. In the horizontal direction, the turret ejection port and the guide part are spaced apart by a design distance. An elastic shock absorber, one end of which is connected to the side of the guide plate away from the turret ejection port, and the other end of which is connected to the turret, is used to absorb shock when the shell casing comes into contact with the guide portion of the guide plate.
[0005] In some embodiments, the elastic damping element is a spring rod, of which two are provided, and both spring rods are located at the top of the guide plate and are set at an acute angle to the turret sidewall.
[0006] In some embodiments, the guide plate includes an installation section fixed to the turret ejection port and a guide section for changing the trajectory of the ejected shell casing. The installation section is rectangular, the guide section is trapezoidal, the guide portion is located on the guide section, and the long side of the guide section is connected to the installation section.
[0007] In some embodiments, a fixing frame is further included, which is connected to the guide plate and the elastic damping member for fixing the guide plate and the elastic damping member to the turret; it includes a connecting rod connected to one end of the guide plate and the spring rod, and a U-shaped connecting frame connected to the other end of the guide plate and the spring rod.
[0008] In some embodiments, the long side of the guide section is longer than the mounting section and extends toward both sides of the mounting section. A protrusion for abutting against the side wall of the turret is provided at the end of the guide section, and the connecting frame is fixed to the protrusion.
[0009] In some embodiments, the connecting frame is rotatably connected to the spring rod.
[0010] In some embodiments, a buffer pad is provided on the side of the protrusion near the turret sidewall.
[0011] In some embodiments, the cushioning pad is made of rubber.
[0012] In some embodiments, the connecting rod and the spring pull rod are fixedly connected by bolts, and the connecting frame and the protrusion are fixedly connected by bolts.
[0013] In some embodiments, the spring of the spring rod is a disc spring or a helical spring.
[0014] The beneficial effects of the technical solutions provided in this application include: This application provides a guiding device for ejecting spent shells from tank shells, comprising: The guide plate is located at the bottom of the turret ejection port and is inclined at an angle to the top surface of the vehicle. The guide plate is equipped with a guide part to change the ejection trajectory of the shell casing and guide the ejected shell casing to the outside of the vehicle. In the horizontal direction, the turret ejection port and the guide part are spaced apart by a design distance. An elastic shock absorber, one end of which is connected to the side of the guide plate away from the turret ejection port, and the other end of which is connected to the turret, is used to absorb shock when the shell casing comes into contact with the guide portion of the guide plate.
[0015] In practice, the guide plate is located at the bottom of the turret ejection port and is angled to the top of the vehicle. The guide plate also has a guide section, with a certain distance between the ejection port and the guide section in the horizontal direction. This design alters the original trajectory of the ejected shells. When the shell is ejected from the turret ejection port, it first contacts the guide section of the guide plate. Because of the horizontal distance between the ejection port and the guide section, the guide section does not guide the shell in the opposite direction, but rather guides it in an arc along the direction of ejection to the outside of the vehicle. This solves the problem in existing technologies where shells fail to be ejected due to poor ejection force, direction, or angle, easily accumulating above the troop compartment. It also avoids the inconvenience of operators climbing onto the roof to collect shells, improving the efficiency and convenience of vehicle operations. Furthermore, because the shells are successfully guided out of the vehicle and do not fall onto the hull, it prevents shells from getting stuck between the turret and the hull when the turret rotates. This ensures that the turret can rotate and fire normally, and will not affect combat operations due to the obstruction of shell casings, thus improving the stability and reliability of tank gun firing.
[0016] The elastic damper is connected at one end to the guide plate on the side away from the turret ejection port, and at the other end to the turret. When the shell casing contacts the guide section of the guide plate, the elastic damper acts as a shock absorber. This not only reduces the impact force generated when the shell casing collides with the guide plate, extending its service life, but also prevents the shell casing from deforming or being damaged due to violent impact, ensuring the integrity of the shell casing. Simultaneously, the elastic damper, combined with the thrust generated by the elastic potential energy released when the spring returns to its restoring position, provides the shell casing with an additional upward initial velocity. This gives the shell casing an initial thrust in addition to its parabolic motion under gravity during flight, allowing it to be ejected higher and farther, thus ensuring the shell casing is ejected outside the vehicle.

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.
[0021] This application provides a guiding device for tank shell ejection, which can solve the problem in the prior art that when a tank's gun fires, the shell casing ejected from the turret ejection window cannot be ejected from the tank and will fall onto the tank.
[0022] See Figure 1 , Figure 3 and Figure 5 As shown, this application embodiment provides a guiding device for tank shell ejection, comprising: The guide plate 1 is located at the bottom of the turret ejection window 41 and is inclined at an angle to the top surface of the vehicle. The guide plate 1 is provided with a guide part 121 for changing the ejection trajectory of the shell casing and guiding the ejected shell casing to the outside of the vehicle. In the horizontal direction, the turret ejection window 41 and the guide part 121 are spaced apart by a design distance. The elastic shock absorber 2 has one end connected to the side of the guide plate 1 away from the turret ejection port 41, and the other end connected to the turret 4, and is used to absorb shock when the shell casing comes into contact with the guide portion 121 of the guide plate 1.
[0023] In practice, the guide plate 1 is located at the bottom of the turret ejection port 41 and is angled towards the top of the vehicle. The guide plate 1 also has a guide section 121, with a certain distance between the turret ejection port 41 and the guide section 121 in the horizontal direction. This design alters the original trajectory of the ejected shell casings. When the shell casing is ejected from the turret ejection port 41, it first contacts the guide section 121 of the guide plate 1. Since the turret ejection port 41 and the guide section 121 are spaced a certain distance apart in the horizontal direction, the guide section 121 does not guide the shell casing in the opposite direction. Instead, it guides the shell casing in an arc along the direction in which it was ejected to the outside of the vehicle. This solves the problem in existing technologies where shell casings fail to be ejected due to poor ejection force, direction, and angle, easily accumulating above the troop compartment. It also avoids the inconvenience of operators having to climb onto the roof to collect shell casings, improving the efficiency and convenience of vehicle combat. Meanwhile, because the shell casings can be successfully guided and ejected outside the vehicle without falling onto the hull, the situation of shell casings getting stuck between the turret 4 and the hull when the turret 4 rotates is avoided. This ensures that the turret 4 can rotate and fire normally without affecting combat operations due to shell casing obstruction, thus improving the stability and reliability of the vehicle's gun firing. In actual use, the guide plate 1 can be set at an angle of 18° to 27° with the top surface of the vehicle.
[0024] like Figures 3 to 5 As shown, one end of the elastic damper 2 is connected to the side of the guide plate 1 away from the turret ejection port 41, and the other end is connected to the turret 4. When the shell casing contacts the guide portion 121 of the guide plate 1, the elastic damper 2 can play a damping role. This not only reduces the impact force generated when the shell casing collides with the guide plate 1, thus extending the service life of the guide plate 1, but also prevents the shell casing from deforming or being damaged due to violent collisions, ensuring the integrity of the shell casing. At the same time, the elastic damper 2, combined with the thrust generated by the elastic potential energy released when the spring returns to its original position, can provide the shell casing with an additional upward initial velocity. This allows the shell casing to have an initial momentum in addition to the parabolic motion caused by gravity when flying in the air, thus enabling it to be thrown higher and farther, thereby ensuring that the shell casing can be ejected outside the vehicle.
[0025] In some alternative embodiments, such as Figures 1 to 3 As shown, the elastic damping component 2 is a spring rod, and there are two of them. Both spring rods are located at the top of the guide plate 1 and are set at an acute angle to the side wall of the turret 4.
[0026] Two spring rods are installed as elastic damping components 2, which can evenly disperse the impact force generated when the shell casing contacts the guide plate 1. At the moment the shell casing is ejected and impacts the guide section 121 of the guide plate 1, the two spring rods work simultaneously to buffer and absorb the impact force from different directions and angles, effectively reducing the local stress borne by the guide plate 1, improving the shock absorption effect and stability of the entire guiding device, reducing the possibility of deformation or damage to the guide plate 1 due to excessive impact force, and extending the service life of the guide plate 1. The two spring rods are both located on the top of the guide plate 1. This layout facilitates its installation on the turret 4 and allows the guide plate 1 to form a lever-like balanced mechanical structure when impacted by the shell casing.
[0027] The spring-loaded rod provides tension at the top, balancing the downward and outward impact forces generated by the shell casing on the guide plate 1. This helps maintain the stability of the guide plate 1, preventing excessive shaking or displacement under impact, and ensuring that the guide section 121 can continuously and accurately guide the shell casing to the outside of the vehicle. The spring-loaded rod is set at an acute angle to the side wall of the turret 4. Different vehicles have different requirements for shock absorption and guidance due to differences in turret 4 structure, ejection force, and direction. The acute angle allows the spring-loaded rod to better match the overall structure of the vehicle while providing shock absorption tension, adapting to the geometry and spatial layout of different vehicle turrets 4, ensuring that the guidance device can be installed smoothly and function properly.
[0028] The adjustable length of the spring-loaded rod facilitates the versatility and customization of the guiding device. In practical applications, the ejection force and frequency of shell casings may vary between different vehicle models or even within the same vehicle under different combat environments. By adjusting the length of the spring-loaded rod, the preload and elasticity of the spring can be altered, thereby adjusting the damping effect and the guiding force of the guide plate 1 on the shell casing. This allows the guiding device to adapt more flexibly to various operating conditions and meet the actual needs of different vehicles.
[0029] In some alternative embodiments, the spring in the spring rod is a disc spring or a helical spring. Disc springs have a unique disc shape, which allows them to generate large elastic deformation within a short axial stroke when subjected to loads generated by the impact of the shell casing, thereby absorbing a large amount of impact energy. During the ejection of tank shells, the impact force of the shell casing on the guide plate 1 is large and the duration is short. This characteristic of disc springs allows them to respond quickly and effectively buffer the impact force, reducing damage to the guide plate 1, connecting frame 32, and the entire guiding device, ensuring the stability and reliability of the device. Helical springs have relatively linear elastic characteristics, meaning that the amount of spring deformation is proportional to the load. This characteristic allows for more accurate prediction and control of the spring deformation under different loads during design and use. By rationally selecting parameters such as the wire diameter, number of turns, and diameter of the helical spring, the spring stiffness can be precisely adjusted to match the impact force of the shell casing, achieving precise control of the buffering effect of the guide plate 1 and ensuring that the shell casing can be stably and accurately guided and ejected.
[0030] In some alternative embodiments, such as Figures 1 to 3 As shown, the guide plate 1 includes a mounting section 11 fixed to the turret ejection port 41 and a guide section 12 for changing the trajectory of the ejected shell casings. The mounting section 11 is rectangular, and the guide section 12 is trapezoidal. The guide part 121 is located on the guide section 12, and the long side of the guide section 12 is connected to the mounting section 11. The rectangular shape of the mounting section 11 of the guide plate 1 facilitates fixed connection with the bottom of the turret ejection port 41, ensuring reliable operation of the guiding device under complex working conditions.
[0031] The guide section 12 is trapezoidal in shape, with its long side connected to the mounting section 11. The trapezoidal shape allows for a gradual change in width across the guide section 12 in the horizontal direction, transitioning from the long side connected to the mounting section 11 to the short side. When a shell casing is ejected from the turret ejection port 41 and impacts the guide section 12, the trapezoidal slope provides a gradually changing guiding force, resulting in a smoother and more stable ejection trajectory. The trapezoidal design reduces material usage and avoids increasing the weight of the device while still fulfilling the guiding function. The lightweight guide plate 1 reduces the overall weight of the vehicle and decreases energy consumption.
[0032] In some alternative embodiments, such as Figures 1 to 3As shown, it also includes a fixing frame 3, which is connected to the guide plate 1 and the elastic damping component 2, and is used to fix the guide plate 1 and the elastic damping component 2 to the turret 4. It includes a connecting rod 31 connected to one end of the guide plate 1 and the spring rod, and a U-shaped connecting frame 32 connected to the other end of the guide plate 1 and the spring rod. The fixing frame 3 tightly connects the guide plate 1 and the elastic damping component 2 (such as the spring rod) together through the connecting rod 31 and the U-shaped connecting frame 32. The connecting rod 31 can accurately position one end of the guide plate 1 and the spring rod, ensuring that their relative positions are fixed; while the U-shaped connecting frame 32 connects and fixes the other end of the guide plate 1 and the spring rod from the other direction, forming a stable, triangular-like mechanical structure. This enhances the connection strength between the guide plate 1 and the elastic damping component 2, preventing parts from loosening or separating when the entire guiding device is impacted by a shell casing, thus ensuring the structural integrity of the device under complex working conditions.
[0033] In some alternative embodiments, such as Figures 1 to 3 As shown, the long side of the guide section 12 is longer than that of the mounting section 11 and extends towards both sides of the mounting section 11. A protrusion 13 for abutting against the side wall of the turret 4 is provided at the end of the guide section 12, and the connecting bracket 32 is fixed to the protrusion 13. The protrusion 13 at the end of the guide section 12 increases the structural strength and rigidity of the end of the guide section 12. When a shell casing impacts the guide section 12, it generates a significant impact force, especially at the end of the guide section 12. The presence of the protrusion 13 effectively disperses and absorbs this impact force, preventing deformation or damage to the end of the guide section 12 due to excessive force, thereby ensuring the structural integrity of the guide section 12 and the normal functioning of its guiding function.
[0034] In some alternative embodiments, such as Figure 1 As shown, a buffer pad 131 is provided on the side of the protrusion 13 near the side wall of the turret 4. The buffer pad 131 is made of rubber. When the shell casing is ejected and impacts the guide plate 1, causing the protrusion 13 to abut against the side wall of the turret 4, a large impact force is generated. The buffer pad 131 is located on the side of the protrusion 13 near the side wall of the turret 4, which can effectively absorb and disperse this impact force and prevent the protrusion 13 from making direct rigid contact with the side wall of the turret 4.
[0035] In some optional embodiments, the connecting frame 32 is rotatably connected to the spring rod. This rotatable connection allows the spring rod to more flexibly adjust its angle and direction of force when subjected to the impact of the shell casing, reducing the risk of damage and extending its service life. In some optional embodiments, the connecting rod 31 is fixedly connected to the spring rod by bolts, and the connecting frame 32 is fixedly connected to the protrusion 13 by bolts.
