Technical Field

The invention relates to a rotary wheel type cannon, in particular to a rotary wheel type cannon capable of preventing a cannonball from exploding in the cannon.

Background

Artillery is an important weapon for killing enemies, destroying equipment and traffic in a long distance, and is increasingly paid more attention. The improvement is continuously carried out for hundreds of years, and although the power is more and more powerful, the working principle of converting the chemical energy of the propellant powder into the kinetic energy of the cannonball is not changed all the time.

The current cannons have a number of drawbacks, all of which are closely related to the conversion of the chemical energy of the propellant charge into the kinetic energy of the cannonball.

First, although the high-temperature and high-pressure gas generated by rapid combustion of the propellant powder can accelerate the cannonball, the temperature of the gun barrel is increased rapidly, the inner diameter of the bore is increased, and the precision of cannonball launching is reduced.

Secondly, great recoil is generated when the cannonball is launched, so that the cannonball retreats, the shooting precision is seriously influenced, and continuous adjustment is needed.

Thirdly, when the cannonball is launched, the fire and the smoke diffuse, the fire and the light go on the sky, the sound such as thunder is generated, and the launching place is exposed quickly. The warrior can destroy the fire-fighting bomb immediately, the survival rate of the cannon is low, and the warrior faces great danger.

Fourthly, the long gun barrel can obtain larger shooting speed of the cannonball, but the long gun barrel seriously reduces the maneuverability of the cannonball, has large target and is easy to be detected by enemies.

This is a new and pioneering bullet feeding mode. This is the second significant creation of the present invention.

After the structure is adopted, because the static loading mode is adopted, the rotating speed of the rotating wheel is gradually increased, the impact force on the shell is small, explosion of explosive powder cannot be caused, and great potential safety hazards are eliminated. This is the third significant creation of the present invention.

After the structure is adopted, the cannonball can automatically move outwards to the bullet holder under the action of centrifugal force as long as the cannonball is pushed to pass through the axis of the rotating wheel. The free length of the spring does not have to be very large by centrifugal force. This is the fourth major creation of the present invention.

With this arrangement, the projectile in the magazine is prevented from entering the chute by the projectile in the chute, so that one projectile is fired per revolution of the wheel. So that the fired projectiles all have the same initial velocity. This is the fifth of the significant creation of the present invention.

After the structure is adopted, the shell in the magazine is prevented from rapidly entering the sliding groove by the shell in the sliding groove, so that the shell is slightly impacted by the wall of the sliding groove when entering the sliding groove, and explosion of explosive powder can not be caused. This is the sixth major creation of the present invention.

As shown in fig. 1 and 5, the outer casing 5 is fixedly connected by a toroidal shell 6 and two side casings 11, and the rotor 1 is located in an inner cavity enclosed by the toroidal shell 6 and the two side casings 11.

As shown in fig. 5, the two side casings 11 are respectively provided with a bearing hole 11a at the center thereof and an upper screw hole 11b at the upper portion thereof.

As shown in fig. 5, the outer circumferential surfaces of the outer rings of the two bearings 12 are fixedly connected to the inner circumferential surfaces of the bearing holes 11a of the two side cases 11, respectively, and the inner circumferential surfaces of the inner rings thereof are fixedly connected to the outer circumferential surfaces of the left-turn shaft 4a and the right-turn shaft 4b of the rotating shaft, respectively. The left end surface of the left rotation shaft 4a is flush with the left side surface of the left housing 11 of the two side housings 11. The right end of the right rotating shaft 4b projects outward from the right lateral face of the right housing 11 in the two side housings 11.

As shown in fig. 5, the two upper screws 13 are respectively engaged with the upper screw holes 11b of the two side cases 11, and the inner ends thereof are respectively fixedly connected with the damping blocks 13 a. When the two upper screws 13 are screwed in from the two side casings 11 respectively and the damping blocks 13a on the two upper screws 13 are pressed on the runner 1 respectively, the rotating runner 1 can be braked rapidly.

As shown in fig. 1 and 5, the circular casing 6 has an axis coincident with the axis of the wheel 1, an upper portion extending out of the barrel 8, an axially central portion of an inner circumferential surface thereof formed with a circular smooth sliding groove 7 for allowing the shell 17 to slide around the axis thereof, a lower portion of the outer circumferential surface thereof formed with a plurality of axial roller grooves 6a, a middle wall thereof formed with a loading door 9 in a radial direction, and an upper wall thereof formed with an axial insertion hole in which an insertion plate 14 is movably installed so as to be movable in the axial direction.

As shown in fig. 5, the chute 7 has a U-shaped radial cross section at the lowest position and an inverted U-shaped radial cross section at the highest position.

As shown in fig. 1 and 5, a roller 10 is embedded in each roller groove 6a, the axis of the roller 10 is parallel to the axis of the toroidal shell 6, most of the circumferential surface of the roller 10 is located in the roller groove 6a, and a small part of the circumferential surface is exposed from the outer circumferential surface of the toroidal shell 6 at the corresponding position.

As shown in fig. 2, 3 and 4, the inner end of the bore 8a of the barrel 8 smoothly communicates with the chute 7 at the corresponding position. The cannonball 17 which is positioned on the bullet holder 3 of the runner 1 starts to do centrifugal motion when rotating to the inner end of the bore 8a in the sliding chute 7 along the clockwise direction, automatically enters the bore 8a along the tangential direction, and then is ejected from the outer end of the bore 8 a; the shell 17, which, during its entry into the bore 8a, prevents another shell 17 adjacent thereto from following it and also entering the bore 8a, which other shell 17 can only rotate in the slide groove 7 in a clockwise direction, has to make one revolution before entering the bore 8a and then being ejected.

As shown in fig. 1, the insert plate 14 movably mounted in the insert hole blocks the inner end of the bore 8a when it is axially inserted into the inner end of the bore 8a, preventing the projectile 17 circularly moving in the clockwise direction in the slide groove 7 from tangentially entering the bore 8a, the projectile 17 being allowed to continue circular movement in the slide groove 7. As shown in fig. 2, 3 and 4, the projectile 17 can only enter the bore 8a tangentially when the insert plate 14 is axially displaced from the inner end of the bore 8 a.

As shown in fig. 1, the loading door 9 has a door opening communicated with the inner cavity of the housing 5 when opened, and when the bullet inlet end of the magazine 2 on the wheel 1 is rotated to the door opening, the magazine cover 16 and the spring 15 are removed, so that the magazine 2 can be loaded with bullets 17 through the door opening and the bullet inlet end.

As shown in fig. 1 and 5, the cannon seat 18 is integrally formed by a base 19 and two side seat plates 20.

As shown in fig. 1 and 5, the upper surface of the base 19 is an arc-shaped concave surface 19 a. The concave surface 19a, whose inner diameter is larger than the outer diameter of the housing 5, has an axial length larger than but close to the axial length of the housing 5, is opposed to the outer circumferential surface of the lower portion of the housing 5, and is in movable contact with the exposed circumferential surface of the rollers 10 mounted on the lower portion of the housing 5, the housing 5 is freely rotatable about the axis, and the housing 5 is prevented from moving in the axial direction by the side seat plates 20. The two side seat plates 20 are respectively provided with horizontal lower screw holes 20a, two lower screws 21 are respectively engaged and installed in the lower screw holes 20a of the two side seat plates 20, when the two lower screws 21 are screwed and pressed on the shell 5, the shell 5 can be prevented from rotating around the shaft, and thus the elevation angle of the gun barrel 8 on the shell 5 is kept unchanged.

As shown in fig. 5, the driving device comprises a power wheel 22 and a hub motor fixedly mounted on the power wheel 22, and the power wheel 22 is coaxially and fixedly connected to the extending end of the right rotating shaft 4b of the rotating shaft. When the hub motor is electrified to work, the power wheel 22 drives the right rotating shaft 4b, the rotating wheel 1 and the left rotating shaft 4a of the rotating shaft to synchronously rotate along the clockwise direction, and the electric energy is converted into the kinetic energy of the cannonball 17 in the magazine 2.

The kinetic energy obtained by the rotor type cannon shell 17 is not converted from the chemical energy of the propellant powder, and the rotor type cannon has a plurality of defects caused by the combustion of the propellant powder, so that the rotor type cannon not only eliminates the defects, but also produces a plurality of effective effects: the temperature of the gun barrel 8 rises slowly, so that the cannonball 17 can be continuously launched, and the power is increased; recoil is not generated when the cannonball 17 is launched, and frequent adjustment is not needed; the cannonball 17 has no smoke, fire light and sound when being launched, the concealment is good, and the survival rate is high; the length of the gun barrel can be greatly reduced, and the maneuverability is obviously improved.

The use method of the rotary wheel type cannon is as follows:

first, brake rotor 1:

as shown in fig. 5, both the upper screws 13 are rotated toward the runner 1, and the damping blocks 13a on both the upper screws 13 are respectively pressed against the runner 1, and after the runner 1 stops rotating, both the upper screws 13 are retracted, so that both the damping blocks 13a on both the upper screws 13 are disengaged from the runner 1.

Secondly, blocking the bore 8a of the gun barrel 8:

as shown in fig. 1, the insert plate 14 located in the insert hole is axially displaced so as to block the bore 8a of the barrel 8.

Third, filling the cannonball 17:

as shown in fig. 1, the loading door 9 is opened, the wheel 1 is rotated to rotate the loading end of the magazine 2 to the door opening of the loading door 9, the magazine cover 16 and the spring 15 in the magazine 2 are removed together, a plurality of shells 17 are loaded into the magazine 2, the magazine cover 16 is then covered again together with the spring 15, and then the loading door 9 is closed.

Fourthly, starting the hub motor:

as shown in fig. 5, the in-wheel motor is connected to a power source, the in-wheel motor drives the power wheel 22, and the power wheel 22 drives the right rotating shaft 4b of the rotating shaft and rotates together with the rotating wheel 1 and the left rotating shaft 4a of the rotating shaft in a clockwise direction.

Fifthly, shooting the cannonball 17:

after the wheel 1 reaches the rated speed, the insert plate 14 is axially moved to withdraw from the bore 8a, and the plurality of projectiles 17 loaded in the magazine 2 are fired one after another, as shown in fig. 2.

Sixthly, stopping the hub motor:

and disconnecting the hub motor from the power supply.

The subsequent operation procedures are the above-described procedures and repetitions.

The movement mode of the wheel type cannon has two preferable schemes.

A first preferred variant of the movement of the wheeled cannon is such that: the rotary wheel type cannon is fixedly arranged on a bottom plate of an automobile or an armored vehicle.

According to the first preferred scheme, the rotary wheel type cannon is flexible in maneuvering, rapid in transferring, convenient to transport, sufficient in reserve ammunition and comfortable for soldiers. The disadvantage is that the target is large and difficult to conceal. This scheme is preferably employed.

A second preferred variant of the movement of the wheeled cannon is such that: two or four wheels are arranged on the rotary wheel type cannon.

In the second preferred embodiment, the target is small and easy to conceal. The defects are poor maneuverability, slow transfer, inconvenient transportation, additional tools for transporting the cannonball and hard and arduous soldiers. The scheme is adopted by reference.

In order to reduce friction and the amount of heat generated by friction, a plurality of lubricating oil pipes are provided in the toroidal shell 6, through which lubricating oil automatically flows to the slide groove 7.
