[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0030] refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 The utility model discloses a new type of fully automatic bullet loading device, which is characterized by comprising a bullet conveying mechanism, a loading mechanism and a magazine 9; wherein,

[0031] The bullet transmission mechanism comprises:

[0032] The bullet storage box has a V-shaped bullet discharge channel, and four support rods 5 are provided below to connect the bottom plate 8;

[0033] The conveyor belt 3 is connected to the opening side of the bullet storage box 1;

[0034] The bullet guide plate 4 is connected to the end of the conveyor belt 3;

[0035] The loading mechanism is arranged below the bullet guide plate 4 and is used to push the bullets 13 into the magazine 9 in an orderly manner. Figure 7 As shown, the interior of the bullet storage box 1 is equipped with two inclined plates, one above the other and tilted in opposite directions. A central opening is formed, slightly larger than the diameter of the bullet 13. When a worker places a bullet 13 into the bullet storage box 1, regardless of its position, it will remain horizontal once it passes through the bullet storage box 1 and lands on the conveyor belt 3. The conveyor belt 3 then transports the bullet 13 to the bullet guide plate 4.

[0036] A further preferred embodiment of the present invention is as follows: the loading mechanism includes a crank connecting rod 12, a bullet pushing block 1203 and a bullet guide box 10; the upper end of the bullet guide box 10 is provided with a bullet ejection hole docking with the bullet guide plate 4; the bullet guide box 10 is provided with the bullet pushing block 1203 at the bottom, and the crank connecting rod 12 is provided on the rear side of the bullet pushing block 1203.

[0037] A further preferred embodiment of the present invention is as follows: the bullet guide box 10 is a hollow regular tetrahedron without a top or bottom surface. The opening is provided with a slope with a cambered cross section. An L-shaped support plate 1002 is provided beside the opening. The top surface of the support plate 1002 is slightly higher than the opening to prevent the bullets from sliding outward. A passage for the bullets to slide down is provided below the second slope 1001. The bullets 13 are oriented and slide into the bullet guide box 12 from the bullet guide plate 4. Since the second cambered slope 1002 with a smaller angle of inclination is provided, the angle of inclination of the second slope 1001 is 46°. The bullets will buffer a portion of gravity on the second slope 1002. Then, when they slide to the bottom, the bullets will be stacked into a neat vertical row. When the push rod 1202 advances, the bullet 13 at the bottom will be pushed into the magazine 9 by the bullet push block 1203. When the push rod 1202 retreats, the bullets remaining in a vertical row will be displaced downward by the distance of one bullet.

[0038] A further preferred embodiment of the present invention is as follows: the crank-connecting rod device 12 includes a motor 1201, a crank telescopic part and two fixed plates 1207, the two fixed plates 1207 are fixedly connected in a vertical shape, the motor 1201 is fixed to the back of the fixed plate 1207, and the crank telescopic part is provided on the front of the fixed plate.

[0039] A further preferred embodiment of the present invention is as follows: Figure 3As shown, the crank telescopic portion includes a rotating block 1204, a transmission shaft 1205, a crank adapter 1209, a push rod 1202 and a fixed block 1208. The rotating block is fixedly connected to the transmission shaft. A fastening bolt 1206 is provided at the end of the transmission shaft. The transmission shaft is vertically connected to the crank adapter through the fastening bolt. The crank adapter is connected to the push rod. Specifically, the crank adapter is vertically connected to the push rod 1202 through a cylindrical sleeve. The push rod 1202 passes through the fixed block 1208. The motor 1201 drives a shaft connected to the rotating block 1204 to make the rotating block 1204 perform a rotational motion. The transmission shaft 1205 is fixed in the slot of the rotating block 1204. As the rotating block 1204 rotates, it forms a crank rocker mechanism with the push rod 1202, pushing the push rod 1202 to reciprocate back and forth, thereby achieving the effect of advancing and retracting the push block 1203.

[0040] A further preferred embodiment of the present invention is as follows: since the thickness of the baffles at both ends of the bullet guide plate 4 gradually increases, a slope 402 in the middle for the passage of the bullet 13 forms a structure that is wide in front and narrow in the back, and is a curved structure. The width of the opening below the bullet guide plate 4 is only slightly larger than the diameter of the bullet. Specifically, the upper opening of the bullet guide plate 4 is 152 mm, the lower opening is 20 mm, and the inclination of the slope 402 is 55°. Since the head of the bullet is lighter than the tail, under the action of gravity, the bullet will form a posture in which the bullet head is upward along the ramp direction during the sliding process to enter the subsequent steps.

[0041] A further preferred embodiment of the present invention is as follows: the present invention is further provided with a servo controller 11 and a loading controller 7. The servo controller 11 is arranged below the bullet storage box 1 and is used to control the opening and closing of the conveyor belt; the loading controller 7 is arranged next to the bullet conveying mechanism. The loading controller 7 is prior art and uses a YueYu brand stepper motor PLC touch control kit, model YF-53. It controls the speed of the conveyor belt 3 and the crank connecting rod 12 by controlling the speed of the motor 1201 to adjust the speed of loading of the bullets 13 and record the number of bullets advanced. The servo controller 11 is used to open and close the conveyor belt 3. In this application, there is no need to program the loading controller 7. Since the above two devices are prior art, no further explanation of their working principles will be given in this application.

[0042] A further preferred solution of the present invention is that the power supply device used in the device is a lithium battery 6 , and all the above components are fixed on the base plate 8 .

[0043] Example: Application of the present invention in the military industry. First, load bullets 13 into the bullet storage box 1, place the magazine 9 at the bottom of the bullet guide box 10, and then turn on the servo controller 11. The bullets 13 slowly move toward the bullet guide plate 4 along with the movement of the transmission mechanism 2 and the conveyor belt 3, eventually falling into the bullet guide box 10. The bullet loading speed is adjusted by the loading controller 7. Simultaneously, the crank connecting rod 12 begins to operate, pushing the bullet push block 1203 back and forth through the push rod 1202 to load the bullets. The number of bullets pushed is recorded on the screen of the loading controller 7. When the bullets 13 are fully loaded, turn off the servo controller 11 to stop loading. The non-electrical components of the fully automatic bullet loading device are all lightweight, and the total weight of the entire device is only 6.5 kg. It is equipped with a dedicated storage box, which is convenient and fast to carry and helps save physical energy.

[0044] After repeated tests, the designed device was used to fully load 25 rounds of bullets into the Type 95 automatic rifle, which was reduced from about 60 seconds to less than 10 seconds. The efficiency was increased by more than 80%, which greatly exceeded the effect of manual loading of bullets.

[0045] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
