Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of shell recycling, in particular to a machine gun shell recycling device. BACKGROUND

[0002] In the prior art, machine guns are collected by manual picking after daily live ammunition shooting, and due to the small caliber and high firing speed of machine guns, especially 30mm machine guns, the ground is full of shells after shooting, and the recovery rate on land is low under normal circumstances, and the number of recovered shells is difficult to meet the requirements, and the efficiency is low. SUMMARY

[0003] In order to solve the defects and problems of 30mm machine gun shell recycling in the prior art, a machine gun shell recycling device is provided.

[0004] The technical scheme adopted by the present application to solve its technical problems is: the machine gun shell recycling device comprises a box body, the box body is composed of a left side plate, a right side plate, a bottom plate and an arc plate, an upper cover plate is arranged at the upper end of the left side plate and the right side plate, a movable plate is connected to the lower end of the left side plate and the right side plate, the arc plate is fixedly connected to the left side plate and the right side plate at both ends, an inlet shell hole is arranged on the side edge of the bottom plate, and the inlet shell hole is matched with the shell throwing window of the turret slope.

[0005] A fixed groove is arranged at the middle position of the bottom plate, and the box body is fixed on the turret slope through the fixed groove and the fixed plate.

[0006] The lower end of the left side plate and the right side plate is further provided with a U-shaped plate, and the lower end of the movable plate is inserted into the U-shaped plate.

[0007] The box body is further provided with a front baffle, and the front baffle is fixed at both ends of the left side plate and the right side plate.

[0008] The left side plate and the right side plate are both provided with heat dissipation holes.

[0009] Compared with existing technologies, the present invention provides a shell casing recovery device for machine guns. A fixing plate secures the casing collector to the turret's inclined surface, ensuring effective casing recovery. The ejection port remains inside the casing collection box as the gun moves up and down, allowing the gun to operate normally at any angle. The device is tested in four main aspects: 1) it ensures continuous casing collection without jamming; 2) it does not affect the original mobility of the equipment; 3) it does not affect the original balance of the equipment (weighing 15.35 kg, within acceptable limits); and 4) it does not affect the original firing performance of the equipment. The casing collection box is made entirely of stainless steel, offering strong corrosion resistance. Its simple structure facilitates disassembly and installation. Casings can be quickly removed by opening the bottom movable plate. With its large capacity design, it can collect casings from three firing groups simultaneously without affecting the gun's rotation or elevation, achieving a 100% recovery rate.

[0010] The following description, in conjunction with the accompanying drawings and specific embodiments, further illustrates a machine gun shell casing recovery device according to the present invention.

[0011] Fig. 1 This is a three-dimensional structural diagram of a machine gun shell casing recovery device according to the present invention;

[0012] Fig. 2 This is an exploded structural diagram of a machine gun shell casing recovery device according to the present invention;

[0013] Fig. 3 This is a bottom view of the structure of a machine gun shell casing recovery device according to the present invention. Detailed Implementation

[0014] like Figs. 1-3 As shown, a shell casing recovery device for machine guns according to the present invention includes a box body 1. The box body 1 consists of a left side plate 2, a right side plate 3, a bottom plate 4, and an arc plate 5. An upper cover plate 6 is provided on the upper end of the left side plate 2 and the right side plate 3, and a front baffle 7 is provided on the lower end of the upper cover plate 6. The two ends of the front baffle 7 are fixed to the left side plate 2 and the right side plate 3. A movable plate 8 is connected to the lower end of the left side plate 2 and the right side plate 3. The movable plate 8 is of a movable structure. The two ends of the arc plate 5 are fixedly connected to the left side plate 2 and the right side plate 3.

[0015] like Figs. 1-3 As shown, a shell casing inlet 9 is provided on the side of the base plate 4. The shell casing inlet 9 is matched with the ejection port on the turret slope. That is, the shell casing inlet 9 is fitted onto the ejection port on the turret slope. The shell casing ejected from the ejection port on the turret slope enters the box 1 through the shell casing inlet 9.

[0016] like Figs. 1-3As shown, a fixing groove 10 is provided in the middle of the base plate 4. The fixing groove 10 is long and narrow. The fixing groove 10 fixes the box body 1 to the turret slope through the fixing plate 11. That is, the fixing screw on the fixing plate 11 passes through the fixing groove 10 and is screwed into the turret slope, thereby fixing the box body 1 to the turret slope.

[0017] like Figs. 1-3 As shown, a U-shaped plate 12 is also provided at the lower end of the left side plate 2 and the right side plate 3. The U-shaped plate 12 cooperates with the movable plate 8. The lower end of the movable plate 8 is inserted into the U-shaped plate 12. When the movable plate 8 needs to be opened, the lower end of the movable plate 8 can be pulled out from the U-shaped plate 12, and then the cartridge cases collected in the box 1 fall out from the movable plate 8. Both the left side plate 2 and the right side plate 3 are provided with heat dissipation holes 13 to dissipate the residual heat of the cartridge cases in the box 1.

[0018] In summary, compared with existing technologies, the shell casing recovery device of this invention fixes the casing collector to the turret's inclined surface using a fixing plate, ensuring effective casing recovery. Furthermore, the ejection port remains inside the casing collection box as the gun pitches and sags, allowing the gun to be used normally at any angle. Four key aspects were tested: first, it ensures continuous casing collection without jamming; second, it does not affect the original mobility of the equipment; third, it does not affect the original balance of the equipment (weight is 15.35 kg, within acceptable limits); and fourth, it does not affect the original firing performance of the equipment. The casing collection box is made entirely of stainless steel, offering strong corrosion resistance. Its simple structure facilitates disassembly and installation. Casings can be quickly removed by opening the bottom movable plate. With its large capacity design, it can collect casings from three firing groups simultaneously without affecting the gun's rotation and pitch, achieving a 100% recovery rate.

[0019] The invention has been described illustratively and not restrictively according to embodiments thereof, but it should be understood that those skilled in the art can make changes and / or modifications without departing from the relevant scope of protection defined by the claims.
