Description

Technical Field

[0001] The present invention relates to the technical field of mechanical bullet pressing, and in particular to an integrated portable fully automatic bullet pressing system. Background Art

[0002] At present, the loading of large-caliber machine gun ammunition belts mainly relies on manual work. Before training or shooting, personnel press large-caliber bullets onto the belt one by one in sequence. This loading process is time-consuming and labor-intensive. It takes about 5 seconds to press a bullet into the belt. If the operation is continued for a while, the personnel's fingers will be sore and weak, and the efficiency will be further reduced. Moreover, when personnel operate by hand, it is easy to forget the number of bullets that have been pressed into the belt. The existing 12.7mm machine gun bullet mechanical manual press requires personnel to first align the bullet with the belt, and then use a lever device to squeeze the bullet into the belt. The loading speed is slow and cannot meet the demand for rapid replenishment of ammunition during shooting.

[0003] The Chinese patents with publication numbers CN209197571U and CN209197571U both use a push rod to push the arranged bullets into the magazine, but these two solutions are only for loading small-caliber bullets into the magazine and cannot be used for loading large-caliber bullets into the ammunition belt. Summary of the invention

[0004] The present invention aims at the deficiencies in the prior art and provides an integrated portable fully automatic bullet pressing system, which is used for quickly pressing 12.7mm machine gun bullets into an ammunition belt to increase the loading speed and enhance the continuous shooting capability.

[0005] In order to achieve the above-mentioned object, the present invention provides an integrated portable fully automatic bullet pressing system, including an ammunition feeding device and an ammunition pressing device, wherein the ammunition feeding device includes an ammunition storage compartment, and the ammunition storage compartment is connected to an ammunition feeding slot; The bullet pressing device includes an ammunition chain driving mechanism and an ammunition pressing mechanism. The ammunition chain driving mechanism includes a rotating shaft. The end of the rotating shaft is connected to a sprocket wheel for carrying and dragging the ammunition chain. The bullet pressing mechanism comprises a cylindrical cam, the cylindrical cam is movably connected to a reciprocating slider, and the reciprocating slider is connected to a bullet pushing rod for pushing the bullets in the bullet feeding slot to the bullet belt; A linkage mechanism is arranged between the cylindrical cam and the rotating shaft.

[0006] Further, the linkage mechanism includes an inner gear ring, the inner gear ring is meshed with a gear, and the gear is connected to the cylindrical camshaft; The inner gear ring is provided with an expansion opening, and a friction surface 1 is provided inside the expansion opening; The rotating shaft is provided with an axial convex ridge, and a sliding seat which can only slide along the axial direction of the rotating shaft is slidably connected to the convex ridge, and the sliding seat is connected to a friction block, and the friction block is provided with a friction surface 2 in the shape of a truncated cone side surface; A stopper is provided at the end of the rotating shaft close to the inner gear ring, and a spring 1 is provided between the stopper and the friction block; A second spring is arranged between the reciprocating slider and the friction block.

[0007] Furthermore, the rotating shaft is provided with a positioning mechanism, the positioning mechanism comprises a positioning wheel coaxial with the rotating shaft, the wheel surface of the positioning wheel is evenly distributed with grooves, and the number of the grooves is the number of teeth of the sprocket divided by four; The positioning mechanism also includes a top block seat, the top block seat is slidably connected with the top block, the end of the top block is provided with a spherical cap, the top of the spherical cap is embedded in the groove, and the other end of the top block is provided with a spring three.

[0008] Furthermore, the number of teeth of the sprocket is greater than or equal to twelve and is a multiple of four.

[0009] Furthermore, four bullet feeding slots are provided, and the four bullet feeding slots correspond to four tooth gaps of the sprockets connected in sequence.

[0014] The beneficial effects of this solution can be known from the description of the above solution. Compared with the prior art, it has the following beneficial effects: (1) This solution is used for 12.7mm machine gun bullets to quickly press bullets into the ammunition belt to increase the loading speed and enhance the continuous shooting capability; (2) It helps to reduce the burden on personnel and avoids the long-term manual loading of large-caliber bullets, which is not only inefficient but also causes hand fatigue and even injury.

DETAILED DESCRIPTION

[0016] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method. Example 1

[0017] like Figure 1As shown, this embodiment is an integrated portable fully automatic ammunition pressing system, including an ammunition feeding device 1 and an ammunition pressing device 2, the ammunition pressing device 2 including an ammunition chain driving mechanism 21, an ammunition pressing mechanism 22 and a box 25, the ammunition chain driving mechanism 21 including a rotating shaft 211, the rotating shaft 211 extends out of the box 25, and its end is connected and passes through two parallel sprockets 212, the sprocket 212 has twelve teeth, and is used to carry and drag the ammunition chain. The ammunition feeding device 1 includes an ammunition storage compartment 11, and the ammunition storage compartment 11 is connected to four ammunition feeding slots 12.

[0018] like Figure 2 As shown, the four bullet feeding slots 12 correspond to the four tooth gaps of the sprocket 212 connected in sequence.

[0019] like Figure 3 As shown, the bullet pressing mechanism 22 includes a cylindrical cam 221, and the cylindrical cam 221 is movably connected to a reciprocating slider 222, and the reciprocating slider 222 is connected to four bullet pushing rods 223, and each of the bullet pushing rods 223 corresponds to a bullet feeding slot 12, and is used to push the bullets in the bullet feeding slot 12 to the bullet belt. The reciprocating slider 222 includes an active slider 2221 and a driven slider 2222 that are fixedly connected, and the active slider 2221 is movably connected to the cylindrical cam 221, and the driven slider 2222 is slidably connected to the rotating shaft 211.

[0020] A linkage mechanism 23 is arranged between the cylindrical cam 221 and the rotating shaft 211, and the linkage mechanism 23 includes an inner gear ring 231, and the inner gear ring 231 is meshed with a gear 232, and the gear 232 is connected to the cylindrical cam 221 axis; the inner gear ring 231 is provided with an expansion opening 233, and a friction surface 1 is arranged on the inner side of the expansion opening 233; the rotating shaft 211 is provided with an axial convex ridge, and a slide seat 234 that can only slide along the axial direction of the rotating shaft 211 is slidably connected by the convex ridge, and the slide seat 234 is connected with a friction block 235, and the friction block 235 is provided with a friction surface 2 in the shape of a truncated cone side surface; a stopper 236 is arranged at the end of the rotating shaft 211 close to the inner gear ring 231, and a spring 1 237 is arranged between the stopper 236 and the friction block 235; a spring 238 is arranged between the reciprocating slider 222 and the friction block 235.

[0021] like Figure 4 As shown, the rotating shaft 211 is provided with a positioning mechanism 24, which includes a positioning wheel 241 coaxial with the rotating shaft 211, and the wheel surface of the positioning wheel 241 is evenly distributed with grooves, and the number of the grooves is three; the positioning mechanism 24 also includes a top block seat 242, the top block seat 242 is arranged on the box body 25, the top block seat 242 is slidably connected with a top block 243, a ball crown is arranged at the end of the top block 243, the top of the ball crown is engaged with the groove, and a spring three 244 is arranged at the other end of the top block 243.

[0022] During operation, the bullets in the magazine 11 fall into the four ammunition feeding slots 12 under the action of gravity.

[0023] Then, the inner gear ring 231 is driven by the motor, the inner gear ring 231 drives the gear 232 and drives the cylindrical cam 221 to rotate, and the cylindrical cam 221 drives the reciprocating slider 222 to reciprocate.

[0024] When the reciprocating slider 222 presses the spring 238 , the spring 238 presses the friction block 235 and the spring 1 237 , so that the friction surface 2 of the friction block 235 presses the friction surface 1 of the inner gear ring 231 , and the inner gear ring 231 provides friction force to the friction block 235 .

[0025] When the friction force is large enough, the positioning wheel 241 of the positioning mechanism 24 will squeeze out the end of the top block 243, and then the friction block 235 will drive the rotating shaft 211 to rotate. By controlling the squeezing time and force of the reciprocating slider 222 on the friction block 235, the positioning wheel 241 can only squeeze out the top block 243 once in one reciprocation of the reciprocating slider 222, so that the end of the top block 243 will fall into the next groove and cannot come out, and further the positioning wheel 241 can only rotate one-third of a circle, that is, just rotate four sprocket 212 tooth gaps.

[0026] Then when the reciprocating slide block 222 breaks away from the spring two 238, the spring one 237 can make the friction block 235 break away from the friction surface one. Simultaneously, the reciprocating slide block 222 continues to move, driving the ejector rod 223 to push the bullet in the feed slot part 12 to enter the bullet belt.

[0027] Repeat this cycle. Example 2

[0028] like Figure 5 As shown, this embodiment is different from the embodiment 1 in that a support seat 26 and a support frame 27 are provided. The support seat 26 is connected to the bottom of the box body 25, and the support frame 27 is seated on the support seat 26. After the end of the rotating shaft 211 passes through the sprocket 212, it is rotated to connect the support frame 27. The weight of the machine gun ammunition chain is relatively large. When the rotating shaft drags the ammunition chain to move, if there is no support frame, the stress at the root of the extended section of the rotating shaft will be relatively large due to the existence of torque, which will affect the service life of the rotating shaft to a certain extent; and because the reaction force given to the rotating shaft by the ammunition chain is sometimes large and sometimes small when it is dragged, it may cause the rotating shaft to shake. The provision of a support frame can effectively solve the above problems.

[0029] Technical features not described in the present invention can be achieved through or by adopting existing technologies and will not be described in detail herein. Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
