[0002] Pneumatic projectile transport uses gas as a power source and a projectile as a carrier to transport items placed inside the projectile through pipes to a designated location. It has a wide range of applications.

[0003] Pneumatic artillery shells are transported using pipelines. If it is a one-to-one transmission, it can be completed by laying a single pipeline. If it is a one-to-many transmission, or a many-to-one transmission, a steering device is required to complete the transfer of the "artillery shells" between pipelines.

[0004] Nowadays, the steering devices used in pneumatic artillery shell transmission on the market are increasingly pursuing simple structures and reducing equipment processing costs; they pursue modular equipment design and require easy processing, installation, and maintenance; since steering devices are generally installed and fixed in mid-air, light weight is also one of the requirements for the development of steering devices.

[0022] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clearly understood, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the embodiments of the present invention and the accompanying drawings. It is obvious that the described embodiments are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0023] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0024] In one embodiment of the present invention, see Figure 1 、 Figure 2 The steering device for pneumatic artillery shell transmission includes an outer frame 2, a rotating body 3, and a pipe 4; the outer frame 2 is provided with an upper plate 201, a lower plate 202, and four No. 1 columns 218, and the outer frame 2 is supported by the combination of these three parts; the upper plate 201 is provided with a motor 211 and a No. 4 pipe port 217; the lower plate 202 is provided with a No. 1 pipe port 214, a No. 2 pipe port 215, and a No. 3 pipe port 216; the pipe 4 is installed in the rotating body 3, and the pipe 4 The upper end is aligned with the No. 4 pipe opening 217, and the lower end is aligned with the No. 1 pipe opening 214. This position is set as the zero point of the rotating body 3. After each operation is completed, the rotating body 3 returns to the zero point, and the motor 211 drives the rotating body 3 to move, so that the lower end of the pipe 4 is aligned with the No. 2 pipe opening 215 or the No. 3 pipe opening 216, so that a passage is formed between the No. 4 pipe opening 217 and the No. 1 pipe opening 214, the No. 2 pipe opening 215 or the No. 3 pipe opening 216, thereby realizing the steering transmission of the "cannonball".

[0025] Furthermore, the upper plate 201 is provided with photoelectric No. 1 203, photoelectric No. 204, photoelectric No. 3 205, limiting column No. 206, and limiting column No. 3 207, wherein the three photoelectrics are arranged in an equilateral triangle position, and the two limiting columns are arranged next to the photoelectrics with their corresponding numbers and away from the position of photoelectric No. 1 203; the upper plate 201 is also provided with a motor 211, a pulley 210 and a belt 208. The motor 211 uses a worm gear motor, and its structural principle is used to realize the self-locking function. The turbine of the motor 211 is connected to the pulley 210; the pulley 210 is connected to the pulley turntable 302 through the belt 208, so that when the motor 211 moves, it can drive the rotating body 3 to run; the lower plate 201 is provided with a rotating shaft 213, and the center of the lower end of the rotating body 3 passes through the rotating shaft 213. When the rotating body 3 rotates, it rotates with the rotating shaft 213 as the center.

[0026] When the motor 211 drives the rotating body 3 to move clockwise into position, the No. 2 photoelectric limiter 204 realizes photoelectric limit, and the No. 2 limit column 206 realizes mechanical limit. When the motor 211 drives the rotating body 3 to move counterclockwise into position, the No. 3 photoelectric limiter 205 realizes photoelectric limit, and the No. 3 limit column 207 realizes mechanical limit. The photoelectric limit and the mechanical limit work simultaneously to ensure that the rotating body 3 is accurately in position.

[0027] Further, if Figure 2-4 The rotating body 3 is provided with a rotating disk 301, a pulley turntable 302, and three No. 2 columns 303. The rotating body 3 is composed of these three parts. When the rotating body 3 is at the zero position, the No. 1 photoelectric 203 works, the No. 1 pipe mouth 214 is connected with the No. 4 pipe mouth 217, and a passage is formed. When the rotating body 3 moves clockwise to the position, the No. 2 photoelectric 204 works, the No. 2 limiting column 206 plays a limiting role, the No. 2 pipe mouth 215 is connected with the No. 4 pipe mouth 217, and a passage is formed. When the rotating body 3 moves counterclockwise to the position, the No. 3 photoelectric 205 works, the No. 3 limiting column 207 plays a limiting role, the No. 3 pipe mouth 216 is connected with the No. 4 pipe mouth 217, and a passage is formed.

[0028] Further, if Figure 2 , Figure 5 The pipe 4 is provided with two elbows 401 and a straight pipe 402, all of which are made of PVC hard pipes. The entire pipe 4 is "S"-shaped. The angle between the straight pipe 402 and the rotating disk 301 is 75 degrees. This angle is selected after measurement and multiple tests to greatly reduce the friction between the "cannonball" and the pipe wall when turning.

[0029] Furthermore, the overall process of a steering device for pneumatic shell transmission is that the steering device realizes three paths through the rotation of the rotating body 3, namely, the three paths formed by the No. 1 pipe port 214, the No. 2 pipe port 215, the No. 3 pipe port 216 and the No. 4 pipe port 217. In actual use, there may be three operating scenarios. The first is a three-to-one merger, that is, the "shell" enters the steering device from the No. 1 pipe port 214, the No. 2 pipe port 215 or the No. 3 pipe port 216, and enters the steering device from the No. 4 pipe port 217. The first is output from pipe port 217, and the "cannonball" completes the lane changing function; the second is one-to-three separation, that is, the "cannonball" enters the steering device from pipe port No. 4 217, and is output from pipe port No. 1 214, pipe port No. 215 or pipe port No. 3 216, and the "cannonball" completes the lane changing function; the third is combined temporary storage, realizing the function of the "cannonball" entering the steering device from any one of the three pipe ports No. 1 214, pipe port No. 215 or pipe port No. 3 216, and outputting from any one of the three pipe ports. The specific implementation requires coordination of pipelines and airflow. For example, using pipe opening 1 214 as an example and pipe opening 2 215 as an example, the operation and working principle of the steering mechanism of the "cannonball" in this mode are explained in detail. Rotating body 3 is at zero position, with pipe openings 1 214 and 4 217 open. The "cannonball" enters from pipe opening 1 214 and exits from pipe opening 4 217 into the temporary storage pipeline. The steering mechanism rotates clockwise, opening pipe openings 215 and 4 217. The "cannonball" then enters from pipe opening 4 217 and exits from pipe opening 215, thus achieving the steering mode of the "cannonball" entering from pipe opening 1 214 and exiting from pipe opening 2 215. Therefore, the coordination of the steering mechanism, external pipelines, and airflow enables arbitrary steering between any two of the four pipe openings.

[0030] The utility model discloses a steering device for transporting pneumatic projectiles. By means of the mutual cooperation among an outer frame 2, a rotating body 3 and a pipe 4, the rotation and the cooperation with the external pipe and the airflow are realized, thereby realizing the direction conversion of the 'projectile' in a variety of pipe conditions in the pneumatic pipe. The device has a wide range of applications, strong adaptability, simple structure, and is easy to install and maintain.

[0031] It is understood that the present invention is described by way of certain embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. Furthermore, under the guidance of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are intended to be protected by the present invention.
