Abstract

The utility model relates to an automatic gun charger for howitzers. The left end of a gun carrier is provided with a propeller, and a gun barrel is arranged on the right end. An n-shaped grooved rail, a middle seat and a V-shaped groove are also orderly arranged on the gun carrier from left to right. A push rod device which forms a slid fit with a rectangular guide rail is arranged in the n-shaped grooved rail. The push rod device is provided with the rectangular guide rail of which the both ends are respectively connected with a left rod, a right rod and a compression spring which is sheathed on the periphery of the right rod. An elastic pivoting element is pivoted on the gun carrier at the lower right end of the V-shaped groove for supporting cartridge cases, and the gun carrier is connected to the upper end of the elastic pivoting element by an extension spring. Thus, the loading time can be shortened, and simultaneously, the loading labor intensity is decreased.

Description

The howitzer automatic gun charger

Technical field

The utility model relates to a kind of howitzer automatic gun charger, refers in particular to the howitzer automatic gun charger that shoots automatically.

Background technology

At present, because the howitzer and the shell case of howitzer separate, the personnel selection work point is not packed into (being that shell loads) in the gun barrel earlier, and is obvious because it is time-consuming longer manually to adorn howitzer and shell caseization respectively, can not adapt to the demand of continuous emission howitzer.

Summary of the invention

The purpose of this utility model provides a kind of howitzer automatic gun charger, when the push rod device promotes shell case, shell case is nested with earlier automatically in the howitzer periphery forms an integral body, enters gun barrel more automatically.

The utility model provides a kind of howitzer automatic gun charger, left end head at gun carriage is provided with a propeller, and a gun barrel is set on its right-hand member head, on gun carriage, also be sequentially provided with ㄇ type grooved rail from left to right, middle base and V-type groove, in ㄇ type grooved rail, be provided with the push rod device of joining with a rectangular guideway cunning, this push rod utensil has two ends to connect the rectangular guideway of left bar and right bar respectively, and be nested with compression spring in right bar periphery, on the gun carriage of the V-type groove bottom righthand side of supporting shell case, be pivoted with an elasticity articulated part, and be connected elasticity articulated part upper end with an extension spring.

The utility model provides a kind of howitzer automatic gun charger, and this elasticity articulated part left side is a perpendicular, and the right side is many inclined-planes of evagination.

The utility model provides a kind of howitzer automatic gun charger, in the V-type groove center wall below howitzer several elastic bearings is set.

The utility model can shorten the time of shooting, and also reduces the labour intensity of ramming simultaneously.

Description of drawings

Fig. 1 is the utility model most preferred embodiment cross-sectional schematic.

Fig. 2 is the A-A generalized section of Fig. 1.

The specific embodiment

Present embodiment comprises that mainly gun carriage 1, push rod device 2, gun barrel 3, propeller 4 and elasticity articulated part 5 constitute, as shown in Figure 1, 2, and wherein:

Gun carriage 1 is provided with ㄇ type grooved rail 11, V-type groove 12, middle base 13, elastic bearing 14 and overhanging arm 15, wherein:

ㄇ type grooved rail 11 is fixedly connected on the gun carriage 1 with its lower end, V-type groove 12 is arranged on the gun carriage 1 of placing shell case 6 and howitzer 7, make shell case 6 and howitzer 7 be in simultaneously with gun barrel 1 concentric position on (shell case 6 and howitzer 7 are to roll into automatically on the V-type groove 12 in the shell box, belong to prior art); There are several elastic bearings 14 (as the spring ball structure) of vertically arranging to be arranged in V-type groove 12 center walls of howitzer 7 belows again, when pushing howitzer 7 to for shell case 6, because the thrust of shell case 6, this howitzer 7 can upwards float, and makes shell case 6 can be socketed on the howitzer 7 swimmingly; And middle base 13 is the vertical arms that are in ㄇ type grooved rail 11 right sides, also is provided with longitudinal hole 131 on it, and these middle base 13 right sides are for the left side against shell case 6; Connect an overhanging arm 15 at V-type groove 12 bottom righthand sides of supporting shell case 6 again,

Push rod device 2 is concentric left bar 22, the right bars 23 that connected respectively by a rectangular guideway 21 and two ends thereof, and be nested with at the compression spring 24 of right bar 23 peripheries and form, wherein this rectangular guideway 21 is slidingly matched with ㄇ type grooved rail 11, left side bar 22 is slided in the centre bore 411 of the slurcam 41 that fits over propeller 4, and right bar 23 sliding fitting in the through hole 131 of middle base 13, these compression spring 24 left ends are resisted against on rectangular guideway 21 sides, and its right-hand member is resisted against on the sidewall of middle base 13.

Gun barrel 3 is fixed on gun carriage 1 right-hand member head (being front end), belongs to prior art.

Propeller 4 is the structures that promote with steam-cylinder piston, belongs to prior art, and it is arranged on gun carriage 1 left end head, and wherein the piston rod front end is provided with slurcam 41, and a centre bore 411 also is set on it.

Elasticity articulated part 5 is that the left side is the flat board on many inclined-planes of evagination for the perpendicular right side, the position is articulated on (V-type groove 12 bottom righthand sides) gun carriage 1 overhanging arm 14 right-hand members with a little axle 51 therebetween, and be connected on the overhanging arm 14 with an extension spring 52 (be provided in a side of shell case 6 sides and do not contact) in the top with shell case 6, these elasticity articulated part 5 left sides are for the right flank against shell case 6, and these elasticity articulated part 5 right sides are for the left surface against howitzer 7.

The course of action of present embodiment and operation principle thereof:

After earlier shell case 6 and howitzer 7 being loaded onto V-type groove 12, the slurcam 41 that starts propeller 4 promotes rectangular guideway 21 to the right, this rectangular guideway 21 (in the ㄇ of gun carriage 1 type grooved rail 11) slides to the right and compresses spring 24, right bar 23 passes longitudinal hole 131 and promotes shell case 6 simultaneously, so, the swing of elasticity articulated part 5 clockwise directions also promotes howitzer 7, be in until this elasticity articulated part 5 and be lower than shell case 6 lower edge positions (about 90 °), at this moment, this shell case 6 is nested with on howitzer 7 to be integral, and continues to advance gun barrel 3 (promptly loading); Then, when propeller 4 did not produce thrust, compression spring 24 freely extended from left, in the through hole 131 of right bar 23 termination indentation middle base 13, can recover again shell case 6 and howitzer 7 are loaded onto V-type groove 12, so can repeat said process.
