[0015] Preferably, the corrugated air cylinder includes a corrugated telescopic body and a limiting plate, which are sequentially stacked from top to bottom below the loading tray, and the limiting plate is in abutment with the inner wall of the hopper for limiting the downward extension of the corrugated telescopic body.

[0016] Preferably, the corrugated telescopic body and the limiting plate have consistent cross-sectional shapes, and the A material position edge on the same side of the corrugated telescopic body and the limiting plate forms one of the discharging gaps with the inner wall of the hopper, and the B material position edge on the same side of the corrugated telescopic body and the limiting plate forms another of the discharging gaps with the inner wall of the hopper.

[0017] Preferably, the inner wall of the hopper is provided with two discharging chutes, the top end and the bottom end of the discharging chute are both open, the A material position edge and the B material position edge of the limiting plate are in abutment with the top end of the two discharging chutes and are in communication with the openings thereof, and the bottom end openings of the two discharging chutes are connected to the discharge port of the hopper.

[0027] Compared with the prior art, the pneumatic shell unloading and conveying device provided by the present application has the following advantages. When the device is used, the shell is poured into the accommodating space of the loading tray through the elastic enclosure. In the process of pouring the shell, the elastic enclosure reduces the collision between the shell and the inner wall of the hopper, thereby preventing the inner wall of the hopper from damaging the shell. After the shell is poured into the accommodating space of the loading tray, the shell is loaded in both the A loading area and the B loading area. First, the A loading area is lifted for unloading. Specifically, the pneumatic control system is controlled to inflate the A air cavity of the bellows air cylinder, and the loading tray is tilted and rotated towards the B loading area, that is, the A loading area is lifted, and the B loading area is lowered. The shell in the B loading area is discharged through the lower discharge channel formed between the feeding gap and the discharging gap to the discharge port at the bottom of the hopper. In addition, it should be noted that the elastic enclosure rotates with the loading tray, which can prevent the shell from being stuck during the discharging process. Then, the B loading area is lifted for unloading. Specifically, the pneumatic control system is controlled to inflate the B air cavity of the bellows air cylinder and deflate the A air cavity. The loading tray is tilted and rotated towards the A loading area, that is, the A loading area is lowered, and the B loading area is lifted. The shell in the A loading area is discharged through another lower discharge channel formed between another feeding gap and another discharging gap to the discharge port at the bottom of the hopper. Similarly, the elastic enclosure still rotates with the loading tray, which can prevent the shell from being stuck during the discharging process. Finally, the A loading area and the B loading area of the loading tray are repeatedly lifted one by one to complete the unloading of the shell in the loading tray.

[0028] In summary, in the process of pouring the shell into the loading tray through the elastic enclosure, the elastic enclosure reduces the collision between the shell and the inner wall of the hopper. After the shell is poured into the A loading area and the B loading area of the loading tray, the A loading area and the B loading area of the loading tray are lifted one by one by the pneumatic extension and retraction of the bellows air cylinder, so that the shells in the A loading area and the B loading area are discharged in batches through the corresponding lower discharge channels to the discharge port of the hopper. This reduces the collision between the shell and the inner wall of the hopper, and avoids the problem of mutual collision and extrusion of a large number of shells caused by simultaneous discharging of the shells. Therefore, the collision damage during the unloading and conveying of the shells is effectively reduced. BRIEF DESCRIPTION OF DRAWINGS

[0055] In addition, please refer to Figure 1 , the corrugated cylinder 4 is arranged in the inner cavity of the hopper 1 and located directly below the load tray 2, the corrugated cylinder 4 is filled with gas to drive its expansion and contraction, the inside of the corrugated cylinder 4 is composed of A gas cavity 411 and B gas cavity 412 which are isolated from each other and arranged symmetrically left and right, the A gas cavity 411 is located directly below the A loading area 21, the B gas cavity 412 is located directly below the B loading area 22, and the two are respectively connected with the pneumatic control system outside the hopper 1 through gas pipes, the pneumatic control system is used for inflating and deflating the A gas cavity 411 and the B gas cavity 412, so that the A gas cavity 411 is stretched upward to lift the A loading area 21, and the B loading area 22 is lowered, and the shell on it is dropped, or the B gas cavity 412 is stretched upward to lift the B loading area 22, and the A loading area 21 is lowered, and the shell on it is dropped, in order to ensure that the shells on the A loading area 21 and the B loading area 22 are orderly dropped, only an A discharge gap is left between the peripheral side of the A gas cavity 411 and the inner wall of the hopper 1, the A discharge gap is located directly below the A feeding gap 23 and forms an A dropping channel therebetween, only a B discharge gap is left between the peripheral side of the B gas cavity 412 and the inner wall of the hopper 1, the B discharge gap is located directly below the B feeding gap 24 and forms a B dropping channel therebetween, and the A dropping channel and the B dropping channel are both communicated with the discharge port 12 of the hopper 1.

[0056] The above structure, when in use, the shell is poured into the containing space of the loading tray 2 through the elastic cover 3, and in the process of pouring the shell, the elastic cover 3 reduces the collision between the shell and the inner wall of the hopper 1, thereby preventing the damage of the shell by the inner wall of the hopper 1. After the shell is poured into the containing space of the loading tray 2, the A loading area 21 and the B loading area 22 both carry the shell. First, the A loading area 21 is lifted to discharge, specifically, the pneumatic control system is controlled to fill air into the A air cavity 411 of the bellows cylinder 4, the loading tray 2 is tilted and rotated towards the B loading area 22, that is, the A loading area 21 is lifted and the B loading area 22 is lowered, and the shell in the B loading area 22 is discharged through the B lower discharge channel to the discharge port 12 at the bottom of the hopper 1. In addition, it should be noted that the elastic cover 3 rotates with the loading tray 2, which can prevent the shell from being stuck during the discharging process. Then, the B loading area 22 is lifted to discharge, specifically, the pneumatic control system is controlled to fill air into the B air cavity 412 of the bellows cylinder 4 and to exhaust air from the A air cavity 411, and the loading tray 2 is tilted and rotated towards the A loading area 21, that is, the A loading area 21 is lowered and the B loading area 22 is lifted, and the shell in the A loading area 21 is discharged through the A lower discharge channel to the discharge port 12 at the bottom of the hopper 1. Similarly, the elastic cover 3 still rotates with the loading tray 2, which can prevent the shell from being stuck during the discharging process. Finally, the A loading area 21 and the B loading area 22 of the loading tray 2 are repeatedly lifted one by one to complete the discharging of the shell in the loading tray 2.

[0057] In summary, in the process of pouring the shell into the loading tray 2 through the elastic cover 3, the elastic cover 3 reduces the collision between the shell and the inner wall of the hopper 1. After the shell is poured into the A loading area 21 and the B loading area 22 of the loading tray 2, the A loading area 21 and the B loading area 22 of the loading tray 2 are lifted one by one by the bellows cylinder 4, so that the shell in the A loading area 21 and the B loading area 22 is discharged in batches through the corresponding lower discharge channel to the discharge port 12 of the hopper 1, which reduces the collision between the shell and the inner wall of the hopper 1 and avoids the problem of mutual collision and extrusion of a large number of shells caused by simultaneous discharging of the shells, thereby effectively reducing the collision damage in the discharging and conveying process of the shell.

[0064] Specifically, please refer to Figure 5 and Figure 6 , a first upper gap is left between the A material level side S-a of the A air cavity 411 and the inner wall of the hopper 1, a second upper gap is left between the B material level side S-b of the B air cavity 412 and the inner wall of the hopper 1, a first lower gap is left between the A material level side S-a of the limiting plate 42 and the inner wall of the hopper 1, and a second lower gap is left between the B material level side S-b of the limiting plate 42 and the inner wall of the hopper 1. Since the cross-sectional shape of the corrugated telescopic body 41 and the limiting plate 42 is consistent, the first upper gap and the first lower gap correspond to each other and are vertically distributed, and the second upper gap and the second lower gap correspond to each other and are vertically distributed, so that the shell on the carrier tray 2 falls vertically, avoiding the occurrence of the jamming phenomenon, to ensure smooth discharge.

[0071] In addition, the application also provides a pneumatic shell blanking and conveying method, which is applied to the above-mentioned pneumatic shell blanking and conveying device and comprises the following steps.

[0072] Step S1: The cartridge case is poured into the receiving space of the loading tray. The pneumatic control system is controlled to inflate the A air chamber of the corrugated air cylinder. The loading tray rotates, and at the same time, the elastic cover and the loading tray move together. The A loading area is raised and the B loading area is lowered. The cartridge case located in the B loading area is lowered through the lower leakage channel to the discharge port at the bottom of the hopper.

[0073] Specifically, the cartridge cases are poured into the A loading area 21 and B loading area 22 of the loading tray 2 through the elastic enclosure 3. The pneumatic solenoid control valve on the A air supply pipe is opened, and the gas pump is controlled to fill the A air chamber 411 with air through the A air supply pipe. The loading tray 2 tilts and rotates towards the B loading area 22, that is, the A loading area 21 is raised and the B loading area 22 is lowered. The cartridge cases located in the B loading area 22 are successively discharged into the discharge port 12 of the hopper 1 through the B discharge channel and the B discharge slide 14.

[0074] Step S2: Control the pneumatic control system to fill the B air chamber of the corrugated air cylinder with air, and at the same time draw air from the A air chamber. The loading pallet rotates in the opposite direction. At the same time, the elastic cover and the loading pallet move together. The A loading area descends and the B loading area rises. The shell located in the A loading area leaks down to the discharge port at the bottom of the hopper through another downward leakage channel.

[0075] Specifically, the pneumatic solenoid control valves on the B air supply pipe and the A air extraction pipe are opened to control the gas pump to fill the B air chamber 412 with air through the B air supply pipe and to extract air from the A air chamber 411 through the A air extraction pipe. The material tray 2 tilts and rotates towards the A material loading area 21, that is, the A material loading area 21 descends and the B material loading area 22 rises. The cartridge case located in the A material loading area 21 is sequentially discharged through the A lower leakage channel and the A discharge slide 14 to the discharge port 12 of the hopper 1.

[0076] Step S3: Repeat S1 and S2 to complete the unloading of the cartridge cases on the loading tray 2.
