It should be pointed out that the landlord's first point is not wrong. In the 1970s, the United States and Europe were not equipped with mortar refilling prevention devices. It was invented by the Soviet Union during World War II. It is a mechanical device, which uses the projectile to pass through the cam of the muzzle collision device to realize whether the muzzle can be reloaded into the bayonet lock of the projectile. This kind of mechanical device has not been popularized because it has to knock against the side of the shell, which will affect the accuracy and range of the shell.

Why does the mortar chamber explode?
Soviet mortars prevent reloading of muzzle fittings.
In China, similar products have been equipped for some time. Later, we changed it into an electronic prompting device, which judged whether to fire or not according to the vibration induction of firing and the electromagnetic characteristics induction of shells, and used red and green light-emitting diodes and buzzes to prompt whether to fire or not, but it could not prevent repeated loading. In our army, it is only a small amount of equipment. Because it is not practical.

Electronic prompt device (arrow); In addition, it should be noted that in an ordinary mortar position, if a gun is repeatedly loaded and causes a "double bomb explosion" accident, it is difficult for these people in the whole position to escape under a dense killing radius of more than ten meters.
About this kind of accident, our army had an influential one in the late 1990s. 12 1 division was training in the course of live-fire shooting, and one gunner was nervous, and the loading speed was too fast, which led to many loading accidents, and almost all members of the artillery group and other artillery groups in the position were killed (10 people were killed on the spot, and 10 people were injured). Since then, the training course has been banned from promotion.
The United States and Europe do not have a large number of such anti-reloading devices, or even have hardly used them. Generally speaking, it is the most common to install a muzzle shock wave attenuation horn at the muzzle of medium and large caliber mortars in the United States to improve the working environment of shooters.

Why does the mortar chamber explode?
The most common muzzle shock wave attenuation flare device of the US military is a flare diffuser.

Many times, when American mortars are fired, the muzzle is not equipped with any accessories at all. The United States also does not attach importance to preventing repeated reloading accidents. Maybe it will this time.
Fuze of American mortar shells;
At present, the general fuze of mortar shells equipped by the US military is M734 series with air turbine power insurance. The fuze is finally released near the ballistic high point far away from the launching position, and there will be no explosion accident caused by repeated filling. However, the cost of this fuse reached more than 230 dollars (the purchase price in 2005). Therefore, in the live ammunition training of some small caliber mortars, the early fuze with pure inertia release insurance can be used, which can trigger detonation at the moment of projectile launch. Pentagon officials also announced that the training of soldiers with 60mm mortars will be completely stopped, indicating that the mortars are 60mm mortars made in the United States. This kind of gun is not equipped with a device to prevent reloading. Generally, it uses cheap traditional mortar fuses, which may lead to this accident.
Why does the mortar chamber explode?
M52 fuse of US mortar shells during World War II (see "Saving Private Ryan", which is this kind of fuse, and it can lose inertia at the moment of firing).
Why does the mortar chamber explode?
A mortar fuse widely equipped in the United States and Europe after the war is in a state of dislocation insurance. (There is no ballistic insurance, and all insurances are released by inertia at the moment of firing. )
Why does the mortar chamber explode?
Section view of mortar shell model equipped with the above fuse. Note: the fuse has been disarmed (the needle has been aimed at the detonator).
Why does the mortar chamber explode?
The M734 mortar fuze currently equipped by the U.S. military should pay attention to the fact that the white wheel in the middle is an air turbine, which has full insurance capability and will not be fully insured until the ballistic high point. This kind of fuse has a wide range of uses and can be used in various sizes, but it is more expensive.
Why does the mortar chamber explode?
M734 has a variety of initiation modes, such as 3-13-foot air explosion, near-ground air explosion below 3 feet, triggered instantaneous explosion and delayed explosion, with strong flexibility.
