[0027] The bullet pressing assembly 7 comprises an entering bullet box 701, the entering bullet box 701 is fixedly installed on the top of the outer shell 1, an entering bullet ejector 702 is slidingly installed in the inner part of the entering bullet box 701, an ejecting bottom plate 703 is fixedly installed in the inner part of the outer shell 1, three ejecting side plates 704 are fixedly installed on the top of the ejecting bottom plate 703, an ejecting block 705 is slidingly installed between any two adjacent ejecting side plates 704, a push plate 706 is fixedly installed on the bottom of the entering bullet ejector 702, a cylindrical support cylinder 707 is fixedly installed on the inner bottom wall of the outer shell 1, a sliding opening 716 is formed on the top of the cylindrical support cylinder 707, a space cylinder 708 is rotationally installed in the inner part of the cylindrical support cylinder 707, a transmission bevel gear 709 is fixedly installed on the left end of the space cylinder 708 and the output end of the motor 10, a driving groove 715 is formed on the outer surface of the space cylinder 708, a groove wheel 710 is fixedly installed on the left end of the rotating wheel 4, a KR10 screw type needle bearing 711 is fixedly installed on the right side of the space cylinder 708 and at the eccentric position, two moving openings 712 are formed on the top of the ejecting bottom plate 703, a push block 713 is fixedly installed on the bottom of the ejecting block 705, and a KR16 screw needle bearing 714 is slidingly installed in the inner part of the sliding opening 716.

[0028] In the embodiment, the crank 2 is used to drive the main shaft 8 to rotate clockwise. The main shaft 8 is a driving shaft, and the main shaft 8 drives the transmission bevel gear 709 to rotate counterclockwise through the bevel gears 9. When the main shaft 8 rotates, the space cylinder 708 rotates by the same angle. The space cylinder 708 rotates, and the bottom end of the KR16 screw needle bearing 714 is driven by the driving groove 715 to move along the sliding opening 716, so that the rotary motion of the space cylinder 708 is converted into the linear reciprocating motion of the KR16 screw needle bearing 714. When the space cylinder 708 rotates 360°, the KR16 screw needle bearing 714 performs a linear reciprocating motion once.

[0029] In this embodiment, when the KR16 screw needle bearing 714 does linear ejection movement, the two ejection blocks 705 will make the bullets do ejection movement forward; when the KR16 screw needle bearing 714 does return movement, the two ejection blocks 705 also do return movement. When the two ejection blocks 705 reach the return limit, the two bullets will fall into the two guide grooves composed of the ejection bottom plate 703 and the three ejection side plates 704.

[0030] In this embodiment, when the two ejection blocks 705 reach the ejection limit, the two bullets will be ejected into the belt in the belt wheel 5. The two ejection blocks 705, the bullet feeding ejector 702, and the push plate 706 are assembled as a whole. When the two ejection blocks 705 do linear reciprocating movement, the bullet feeding ejector 702 and the push plate 706 also do linear reciprocating movement.

[0031] In this embodiment, the bullet feeding ejector 702 is equipped with a circular arc tip at the end and a wave plate at the tail. When the bullet enters the bullet feeding box 701, the bullet feeding ejector 702 does return movement, and the bullet feeding ejector 702 will pull the bullet to adjust the position of the bullet entering the bullet feeding box 701 to be horizontal. When the bullet feeding ejector 702 does ejection movement, the bullet feeding ejector 702 will eject the two bullets into different two guide grooves. The space cylinder 708, the KR10 screw type needle bearing 711, and the groove wheel 710 are assembled as a whole. When the space cylinder 708 rotates, the KR10 screw type needle bearing 711 rotates eccentrically at the right end of the space cylinder 708 and enters the groove of the groove wheel 710, and the KR10 screw type needle bearing 711 drives the groove wheel 710 to rotate, which can make intermittent circular movement. When the space cylinder 708 rotates 360 degrees, the groove wheel 710 rotates 60 degrees.

[0032] In this embodiment, when the groove wheel 710 does circular movement, the rotating wheel 4 will be driven to rotate, and the belt wheel 5 will also rotate by the same angle, thereby driving the belt to feed bullets. The belt wheel 5 has a total of 12 bullet feeding grooves, and two bullets are assembled at a time. When the groove wheel 710 rotates 60 degrees, the belt wheel 5 also rotates 60 degrees.

[0033] In summary, the double-row plug-in loading machine, by setting the crank 2 and motor 10, by rotating the crank 2 to drive the main shaft 8, the main shaft 8 rotates through the bevel gear 9 and the meshing transmission bevel gear 709 to rotate and perform single pressing operation, and at the same time, the output shaft of the motor 10 can drive the main shaft 8 to rotate through the transmission bevel gear 709, which can be switched by manual and motor 10 driving, by setting the bullet pressing assembly 7, only one person is needed to operate, effectively solving the problems of time-consuming and labor-consuming, poor working continuity and the like in manual bullet pressing; greatly improve the bullet pressing efficiency; play a key role in improving the technical and tactical performance of the tank; suitable for 12.7mm caliber ammunition chain type weapon equipment, making it easy to press bullets, double-shot feeding and pressing, manual and electric switching, solving the bullet loading structure for guns, which must be placed in the predetermined direction by manually pressing the bullet head and bullet tail in advance during use, time-consuming and labor-intensive, greatly reducing the bullet loading efficiency of the gun.
