As shown in fig. 2 to 9, when the inside of the main air duct 52 is ventilated, a part of air flow is ejected from the outlet of the main air duct 52 to fire the bullet in the loading chamber 54, and the other part of air flow enters the branch air duct 555 and pushes the slider 552 to move backward, at this time, the driving spring 556 is compressed, and the swing lever 553 hinged to the slider 552 rotates relative to the slider 552 while following the backward movement of the slider 552, and in this process, the push post 554 on the swing lever 553 withdraws from one ratchet groove 551 and moves into the other ratchet groove 551, and since the push post 554 on the swing lever 553 is engaged with the ratchet groove 551 on the rotating wheel 53 and the positioning device 56 applies a force to the rotating wheel 53, the rotating wheel 53 does not rotate during the withdrawal and movement of the push post 554 from one ratchet groove 551 into the other ratchet groove 551. When the bullet is fired, the air pressure in the branch air channel 555 is released, the compressed driving spring 556 rebounds to push the sliding block 552 to slide forwards, in the process, the swinging rod 553 pushes the groove wall of the ratchet groove 551 through the pushing column 554 on the swinging rod 553, the pushing force of the pushing column 554 to the rotating wheel 53 is larger than the acting force exerted by the positioning device 56 to the rotating wheel 53, so that the positioning device 56 is released to position the rotating wheel 53, the other bullet loading cavity 54 on the rotating wheel 53 rotates to a position aligned with the outlet of the main air channel 52, at the moment, the swinging rod 553 rotates downwards relative to the sliding block 552 under the action of gravity, the pushing column 554 on the swinging rod 553 falls into the other ratchet groove 551 downwards, and when the loading cavity 54 rotates to a position aligned with the outlet of the main air channel 52, the positioning device 56 on the base positions the rotating wheel 53 again, so that automatic bullet feeding is completed. The above-mentioned process is repeated in this way, so that continuous ammunition feed can be realized. In the whole bullet feeding process, when the driving device 55 works to drive the rotating wheel 53 to rotate, the positioning device 56 releases the positioning, and when the driving device 55 does not work, the positioning device 56 positions the rotating wheel 53, so that the driving device 55 is in linkage fit with the positioning device 56 to rotate the rotating wheel 53 to a required position and can stop positioning after reaching the required position. The whole structure is simple and compact, automatic bullet supply is realized by utilizing air flow, the design is very ingenious, the bullet blocking phenomenon can not occur, and the shooting precision is improved.
A torsion spring (not shown) is disposed between the oscillating rod 553 and the slider 552, so that a force against the ratchet teeth 551 can be applied to the pushing post 554, and the oscillating rod 553 can not rotate by mistake, so that the action is smoother.
As shown in fig. 9, the main air duct 52 is provided with a solenoid control valve 57 dividing it into a front main air duct 521 and a rear main air duct 522, and the outlet of the rear main air duct 522 is aligned with the corresponding loading chamber 54. The electromagnetic control valve 57 which divides the main air passage 52 into the front main air passage 521 and the rear main air passage 522 is arranged on the main air passage 52, so that the control structure of the hammer impact valve is changed, when the semi-automatic air gun shoots, the electromagnetic control valve 57 can be controlled by an electronic switch, and then the air flow on-off is controlled by the electromagnetic control valve 57, the electromagnetic control valve 57 is stable to open and close, the vibration is small, and the shooting precision can be improved.

After the bullet is fired, the electromagnetic coil 577 is powered off, the control spring 574 pushes the electromagnetic moving iron 573 to move upwards, and the valve core 572 is pushed to move through the valve core connecting rod 575, so that the valve is closed again. Therefore, the movement of the valve core 572 is controlled by the energization or deenergization of the electromagnetic coil 573, and the stroke of the valve core 572 can be short, generally about 5mm, so that the on-off of the air flow can be controlled more smoothly, the vibration is small when the semiautomatic air gun shoots, and the shooting precision can be improved. Further, the valve element stroke adjustment knob 578 can adjust the compression amount of the control spring 574 to adjust the stroke of the valve element 572, and can control the air output in a wide range, so that even when different weight bullets are used, the bullet initial speed can be appropriately adjusted.

When the driving device 55 drives the rotating wheel 53 to rotate, the clamping columns 562 are extruded by the arc-shaped grooves 561, the positioning device 56 releases the positioning of the rotating wheel 53, and when the driving device 55 does not drive the rotating wheel 53 to rotate any more, the rotating wheel 53 is at a proper position as required, and at the moment, the clamping columns 562 are clamped with the arc-shaped grooves 561 on the rotating wheel 53, so that the rotating wheel 53 is positioned. In the whole bullet feeding process, when the driving device 55 works, the positioning device 56 releases the positioning of the rotating wheel 53, and when the driving device 55 does not work any more, the positioning device 56 relocates the rotating wheel 53, so that the linkage of the driving device 55 and the positioning device 56 is realized, and the stable automatic bullet feeding is completed.
As shown in fig. 2 and 7, the sliding block 552 is provided with a guide hole 557, the base 51 is provided with a guide column 558 inserted into the guide hole 557 and guiding when the sliding block 552 slides, and the outlet of the branch air channel 555 is positioned at the end of the guide column 558. Through the cooperation of the guide hole 557 and the guide column 558, and the air current in the branch air flue 555 directly lets in the guide hole 557 from the guide column 558 tip, can make slider 552 slide very steadily.
As shown in fig. 11, the rotating wheel 53 is partially exposed to the base 51, the base 51 is provided with an upper bullet groove 58 opposite to the exposed bullet loading cavity 54, the base 51 is provided with a pushing rod 59 capable of sliding relative to the upper bullet groove 58 to push the bullets in the upper bullet loading cavity 54 into the bullet loading cavity 54, and the inner wall of the bullet loading cavity 54 is provided with a convex positioning rib capable of extruding and positioning the bullets therein. When loading the bullet into the loading chamber 54, the bullet is put into the loading groove 58 from the side of the base 51, and then the pushing rod 59 is pushed forward, so that the bullet is pushed into the loading chamber 54, and the positioning ribs protruding from the inner wall of the loading chamber 54 can apply a certain extrusion force to the bullet, and the extrusion force is preferably large enough so that the bullet does not fall out from the loading chamber 54. After one bullet is loaded, the rotating wheel 53 is rotated to load another bullet in the same way, so that the bullet loading cavities 54 on the rotating wheel 53 can be filled with the bullets repeatedly. By adopting the bullet loading mode, the traditional semi-automatic rifle is prevented from being required to disassemble the rotating wheel 53 to finish bullet loading and reinstallation and disassembly processes of the rotating wheel 53 are avoided, so that bullet loading is more convenient and rapid.
