Abstract

The utility model relates to an automatic mortar shell loading mechanism. A vertical projectile box which supports on a projectile frame is arranged on the side between a propulsion seat and a projectile barrel; an opening in the face of the lower side of the propulsion seat is arranged on the vertical projectile box; a movable floor which can glide along the radial direction is arranged on the bottom surface of the projectile box; guide tracks matched with the cross rail grooves on the projectile frame, are arranged on both sides of the movable floor; a cam plate is arranged on the guide tracks facing the propulsion seat; a side spring is connected with the projectile frame back; side rollers are arranged on one side of the propulsion seat which matches with the cam plate of the movable floor; a centring tank is arranged on the lengthways centre of the projectile frame between the propulsion seat and the projectile barrel. The utility model has the advantages of saving time for loading mortars, and simple structure.

Description

Automatic mortar shell loading mechanism

The utility model relates to a kind of automatic ramming device, and it is applicable to shooting automatically of mortar.

At present, the shell of mortar is under the effect of air rammer cylinder, automatically promoting shell by advance seat loads, launches, advance seat reposition then, but shell remains and manually installs between advance seat and the gun barrel, the time that shoots long (generally adorn 1 shell and need 1 minute), obviously, the mortar that fires shells continuously for needs is incompatible.

The purpose of this utility model is that a kind of mortar automatic gun charger will be provided, can directly utilize advance seat to promote shell automatically and load, launch, and the course of action of advance seat reposition then, simultaneously, shell enters between advance seat and the gun barrel automatically.

The purpose of this utility model is achieved in that the side between advance seat and gun barrel is provided with the vertical shell box that is supported on the gun carriage, its downside in the face of advance seat has opening, be provided with the movable floor that can radially slide in shell box bottom surface, its two bottom sides have with gun carriage on the guide rail that matches of transverse guide rail groove, lobe plate is arranged, carry advance seat one side and be connected gun carriage facing to advance seat with the side spring, advance seat one side that matches with the lobe plate of movable floor is provided with sidewinders son, and the gun carriage longitudinal center between advance seat and gun barrel is provided with centering chamfer.When the advance seat fall back process, roller on the advance seat contacts with lobe plate, until the advance seat reposition, while movable floor compressed side spring, outwards move along transverse guide rail groove, shell can roll out on the centering chamfer of gun carriage from big gun spring case open lower side, and advance seat promotes shell and enters gun barrel, and movable floor is closed shell box bottom again.

Because adopt such scheme: shell need not manually shoot, and automatic equipment that need not be special just can reach automatic ramming again, the time that shoots shortens (general per minute can be adorned 10 shells) greatly, and structure is simple again, cost is extremely low.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the schematic top plan view of embodiment of the present utility model.

Fig. 2 is the A-A cutaway view of Fig. 1 of embodiment of the present utility model.

Fig. 3 is the front elevational schematic of embodiment of the present utility model.

Among the figure: 1. gun carriage, the 1a. transverse guide rail groove, 1b. indulges guide-track groove, the 1c. centering chamfer, 2. advance seat, 2a. sidewinders son, 3. gun barrel, 4. propulsion cylinder 5. returns cylinder, 6. shell box, 7. movable floor, 7a. guide rail, 7b. lobe plate, 7c. side spring.

In the embodiment shown in Fig. 1～3:

Shell box 6 is metal shells of end face opening, end face has the lid that can open, for placing shell, the downside of facing advance seat 2 also has an opening, when the movable floor 7 of shell box 6 bottom surfaces outwards moves to certain distance, shell (main body is a cylinder) from then on opening rolls out, and shell box 6 is to connect and be supported on the gun carriage 1 with support.

Movable floor 7 is metallic plates of supporting shell, its two bottom sides has guide rail 7a, can slippage on the guide-track groove 1a that gun carriage 1 matches, have the lobe plate 7b of band oblique line facing to advance seat 2 one sides, carry advance seat 2 one sides and have the side that side spring 7c is connected gun carriage 1.

Gun carriage 1 is supported advance seat 2, gun barrel 3, propulsion cylinder 4, is returned cylinder 5, shell box 6 and movable floor 7, and the guide rail 7a of movable floor 7 bottoms can slippage on the transverse guide rail groove 1a of gun carriage 1, advance seat 2 can slippage on the vertical guide-track groove 1b of gun carriage 1, the shell that rolls out in the shell box 6 is positioned on the centering chamfer c of gun carriage 1 automatically, push gun barrel for advance seat 2, centering chamfer 1c is that 120 ° V-type groove is intersected on the two sides.

Claims

A kind of mortar automatic gun charger comprises gun carriage, advance seat, gun barrel, it is characterized in that: the side between advance seat and gun barrel is provided with the vertical shell box that is supported on the gun carriage, its downside in the face of advance seat has opening, be provided with the movable floor that can radially slide in shell box bottom surface, its two bottom sides have with gun carriage on the guide rail that matches of transverse guide rail groove, facing to advance seat lobe plate is arranged, carry advance seat one side and be connected gun carriage with the side spring, advance seat one side that matches with the lobe plate of movable floor is provided with sidewinders son, and the gun carriage longitudinal center between advance seat and gun barrel is provided with centering chamfer.
