Technical Field
[0001] This utility model belongs to the field of cartridge case recycling technology and relates to a portable cartridge case recycling device. Background Technology
[0002] In routine military training, small arms firing drills are required. The spent cartridge cases need to be collected and reused, so it is necessary to collect them.
[0003] For example, patent (CN220339227U) discloses an automatic cartridge case recovery vehicle, which describes "including a handle, a push rod fixedly connected to the handle, a cartridge case collector housing fixedly connected to the end of the push rod away from the handle, a collection hole for cartridge cases to enter at the bottom of the cartridge case collector housing, and casters fixedly connected to the bottom of the cartridge case collector housing, a battery fixedly connected to the push rod, and an electromagnet for collecting cartridge cases on the ground, with a collection compartment for collecting cartridge cases on the electromagnet on one side of the collection hole. This utility model is equipped with an electromagnet, which has magnetism when energized and can collect cartridge cases on the ground, but loses its magnetism when the electromagnet is de-energized, and the cartridge cases adsorbed on the electromagnet will automatically fall off for easy cleaning."
[0004] The existing technology has the following technical defects:
[0005] When the above-mentioned device is used to recover cartridge cases, it needs to be stopped after the electromagnet is full of cartridge cases. Then the electromagnet needs to be de-energized before the cartridge cases can be collected again. This method is relatively slow because it needs to be stopped intermittently. It also makes it impossible to observe in time whether the electromagnet is full of cartridge cases, which can easily lead to missed cartridge cases. Utility Model Content
[0006] The technical problem to be solved by this utility model is that when the above-mentioned device is recycling cartridge cases, after the electromagnet is full of cartridge cases, the device needs to be stopped, and then the electromagnet needs to be de-energized before collecting the cartridge cases again. This method requires stopping at irregular intervals, which makes the work efficiency relatively slow and makes it impossible to observe in time whether the electromagnet is full of cartridge cases. Therefore, it is easy to cause the cartridge cases to be missed. To overcome the shortcomings of the prior art, a portable cartridge case recycling device is provided.

[0009] The shell-collecting assembly includes a collecting roller, which is located on the inner side of the fixed frame away from the movable housing. The collecting roller is rotatably connected to the fixed frame. A first conveyor belt is located on the inner side of the fixed frame near the collecting roller.

The output end of the first drive motor is fixedly connected to the drive shaft near the collecting roller. A transmission assembly is located on the inner side of the protective shell.
[0010] The transmission assembly includes a second transmission belt group, which is located between the end of the collecting roller outside the fixed frame and the transmission shaft. The collecting roller is connected to the transmission shaft via the second transmission belt group. The two transmission shafts are provided with a first transmission belt group at the end near the first drive motor, and the two transmission shafts are connected to each other via the first transmission belt group.
[0011] A scraper plate is slidably connected to the inner side of the end of the collecting plate near the electromagnet. The top of the scraper plate extends to the outer side of the collecting plate. Multiple telescopic springs are evenly fixed to the lower end of the scraper plate. The end of the telescopic spring away from the scraper plate is fixedly connected to the collecting plate.
[0012] A baffle plate is provided on the inner side of the end of the collecting plate away from the scraping plate. Limiting sliders are fixed at both ends of the baffle plate. A sliding groove is provided at the position of the collecting plate corresponding to the limiting slider. The limiting slider is slidably connected to the collecting plate through the sliding groove. Multiple baffle rods are uniformly fixed on the inner side of the movable box away from the collecting plate.
[0013] The lifting assembly includes a movable connecting seat, which is fixed at one end of the fixed frame near the movable housing.

A lifting motor is fixed at the top end of the movable housing at a position corresponding to the lifting screw. The output end of the lifting motor is fixedly connected to the lifting screw.
[0014] Working process or working principle:
[0015] During operation, when the fixed frame needs to be moved closer to the ground, the lifting motor is first started, causing the lifting screw to rotate. As the lifting screw rotates, it moves the fixed frame, which is fixed to the movable connecting seat, through a threaded connection. This brings the collecting roller into contact with the ground for easy shell pickup. Once the collecting roller is in contact with the ground, the first drive motor is started, causing the drive shaft to rotate. The rotation of the drive shaft, via the first and second drive belt groups, simultaneously rotates and transports the collecting roller and the first conveyor belt. The rotating collecting roller pushes the shells on the ground to the top of the first conveyor belt. Evenly spaced baffles on the outer side of the first conveyor belt effectively prevent the shells from falling. Then, the first conveyor belt transports the shells or other impurities to the top of the second conveyor belt, completing the shell pickup process. As the shells and impurities are transported to the top of the second conveyor belt, they are further transported away. During the conveyor belt operation, cartridge cases are attracted by electromagnets, while other impurities fall to the outside as the second conveyor belt moves along. A reciprocating motor, activated by a third transmission belt, drives a reciprocating screw. As the screw rotates, it drives a cartridge collection plate to reciprocate via a threaded connecting block. When the collection plate moves from the end of the electromagnet closer to the collecting roller to the end further away, the scraper, under the elasticity of a telescopic spring, comes into contact with the lower end of the electromagnet. The scraper removes the cartridge cases attracted to the lower end of the electromagnet. When the scraper detaches from the electromagnet, the cartridge cases fall to the inside of the collection plate. When the baffle plate contacts the baffle rod, the baffle rod slides along a groove, causing the baffle plate to move upwards. This allows the cartridge cases inside the collection plate to fall from near the baffle plate into the cartridge collection box, thus completing the cartridge case collection process.
[0016] Compared with the prior art, the beneficial effects of this utility model are: through the cooperative structural design of the shell pickup component and the collection component, when recovering shell casings in the firing range, as the device moves, the shell pickup component first transports the shell casings to the inside of the moving box, and then the collection component collects the shell casings, which effectively improves the working efficiency of the device. At the same time, the device can work continuously to collect the shell casings adsorbed on the electromagnet, which enhances the practicality of the device.
[0017] The design of the scraper plate, telescopic spring, baffle plate and collection box allows the shell casings attracted to the lower end of the electromagnet to be removed as the collection plate moves back and forth, and then collected inside the collection box, thus completing the collection work. This eliminates the need for manual stopping to clean the shell casings at regular intervals, improving the working efficiency of the device. Attached Figure Description

[0026] Example 1
[0027] like Figures 1 to 7As shown, the device includes a movable housing 1. A push handle 3 is fixed to the top of one end of the movable housing 1, and a fixed frame 4 is provided at the other end of the movable housing 1. To facilitate the movement of the device, movable wheels 2 are rotatably connected to the corners on both sides of the movable housing 1. To facilitate the supply of power to the device, a storage battery 8 is provided on the inner side of the top of the movable housing 1. A shell-collecting assembly is provided on the inner side of the fixed frame 4. A lifting assembly is provided on the end of the fixed frame 4 near the movable housing 1. The fixed frame 4 is connected to the movable housing 1 through the lifting assembly. A collection assembly is provided on the inner side of the movable housing 1 for sorting and collecting shell casings. The collection assembly includes a second conveyor belt 17, which is located on the inner side of the end of the movable housing 1 near the fixed frame 4. A second drive is fixed on the inner side of the movable housing 1 at a position corresponding to the second conveyor belt 17. The output end of the second drive motor 18 is fixedly connected to the rotating shaft inside the second conveyor belt 17. An electromagnet 16 is fixed inside the movable housing 1 and above the second conveyor belt 17. The electromagnet 16 is electrically connected to the battery 8. The lifting assembly includes a movable connecting seat 9, which is fixed at one end of the fixed frame 4 near the movable housing 1. The movable connecting seat 9 is slidably connected to the movable housing 1. A lifting screw 10 is rotatably connected inside the movable housing 1 and at a position corresponding to the movable connecting seat 9. The movable connecting seat 9 is threadedly connected to the lifting screw 10. The top end of the lifting screw 10 extends to the outer side of the top end of the movable housing 1. A lifting motor 6 is fixed at the top end of the movable housing 1 and at a position corresponding to the lifting screw 10. The output end of the lifting motor 6 is fixedly connected to the lifting screw 10.
[0028] When it is necessary to move the fixed frame 4 closer to the ground, the lifting motor 6 is first started, which drives the lifting screw 10 to rotate. When the lifting screw 10 rotates, it drives the fixed frame 4, which is fixed to the moving connecting seat 9, to move through the moving connecting seat 9, so that the collecting roller 5 contacts the ground to facilitate shell collection. Through the cooperative structural design of the shell collection component and the collecting component, when recovering shells in the firing range, as the device moves, the shell collection component first transports the shells to the inside of the moving box 1, and then the collecting component collects the shells, which effectively improves the working efficiency of the device. At the same time, the device can work continuously to collect the shells adsorbed on the electromagnet 16, which enhances the practicality of the device.
[0029] The collecting assembly also includes a casing plate 19, the inner side of which is sloped to facilitate the ejection of spent cartridge cases. The casing plate 19 is located inside the movable housing 1 and between the electromagnet 16 and the second conveyor belt 17. The casing plate 19 is slidably connected to the movable housing 1. To facilitate the movement of the casing plate 19, connecting blocks 20 are fixed on both sides of the casing plate 19. A reciprocating screw is rotatably connected to the inner side of the movable housing 1 at a position corresponding to the connecting blocks 20. 21. The connecting block 20 is threadedly connected to the reciprocating screw 21. A reciprocating motor 22 is installed at the middle position of the end of the two reciprocating screws 21 away from the second conveyor belt 17. In order to facilitate the simultaneous rotation of the two reciprocating screws 21 when the reciprocating motor 22 is started, the reciprocating motor 22 is fixedly connected to the moving box 1. Both reciprocating screws 21 are connected to the output end of the reciprocating motor 22 through the third transmission belt group 23. In order to facilitate the centralized collection of cartridge cases, the inner side of the moving box 1 and located on the cartridge case collecting plate 1 A cartridge case 26 is slidably connected to the end of the cartridge case 19 furthest from the electromagnet 16. To facilitate scraping away spent cartridge cases located below the electromagnet 16 when the cartridge case collecting plate 19 moves from the electromagnet 16 toward the cartridge case collecting box 26, a scraper plate 27 is slidably connected to the inner side of the end of the cartridge case collecting plate 19 closest to the electromagnet 16. The top of the scraper plate 27 extends to the outer side of the cartridge case collecting plate 19. Multiple telescopic springs 28 are evenly fixed to the lower end of the scraper plate 27. The ends of the telescopic springs 28 furthest from the scraper plate 27 are connected to the cartridge case collecting plate. 19 Fixed connection; A baffle plate 24 is provided on the inner side of the end of the collecting plate 19 away from the scraper plate 27. In order to facilitate the opening of the baffle plate 24 when it moves to a specific position, so that the cartridge case can be moved out from the inside of the collecting plate 19, both ends of the baffle plate 24 are fixed with limit sliders 29. A sliding groove is provided at the position of the collecting plate 19 corresponding to the limit slider 29. The limit slider 29 is slidably connected to the collecting plate 19 through the sliding groove. Multiple baffle rods 25 are evenly fixed on the inner side of the movable box 1 away from the collecting plate 19.
[0030] When the cartridge cases and impurities are conveyed to the top of the second conveyor belt 17, the cartridge cases are attracted by the electromagnet 16 as the second conveyor belt 17 conveys them, while other impurities fall to the outside as the second conveyor belt 17 conveys them. By starting the reciprocating motor 22, the reciprocating motor 22 drives the reciprocating screw 21 to rotate through the third transmission belt group 23. When the reciprocating screw 21 rotates, it drives the collecting plate 19 to reciprocate through the connecting block 20 threaded to it. When the collecting plate 19 moves from the end of the electromagnet 16 near the collecting roller 5 to the end away from the collecting roller 5, the scraper plate 27 is at this time extending and retracting the cartridge case. Under the elastic action of the spring 28, the top of the scraper 27 is in contact with the lower end of the electromagnet 16. When the scraper 27 moves, it scrapes off the cartridge cases adsorbed on the lower end of the electromagnet 16. When the scraper 27 moves to the point of disengaging from the electromagnet 16, the cartridge cases will fall to the inside of the cartridge case collecting plate 19. When the baffle plate 24 moves to contact the baffle rod 25, the baffle rod 25 will slide along the groove as the cartridge case collecting plate 19 moves. At this time, the baffle plate 24 will move upward, so that the cartridge cases inside the cartridge case collecting plate 19 can fall from the position near the baffle plate 24 into the inside of the cartridge case collecting box 26, thereby completing the collection of cartridge cases.
[0031] Example 2
[0032] like Figures 1-4 As shown, to facilitate the pickup of spent cartridge cases located on the ground, the cartridge case pickup assembly includes a collection roller 5. The collection roller 5 is located on the inner side of the fixed frame 4 away from the movable housing 1. The collection roller 5 is rotatably connected to the fixed frame 4. A first conveyor belt 7 is provided on the inner side of the fixed frame 4 near the collection roller 5. Multiple baffles are evenly fixed on the outer side of the top of the first conveyor belt 7. A protective shell 11 is fixed on one side of the outer side of the fixed frame 4. A first drive motor 12 is fixed on the outer side of the protective shell 11. Both ends of the inner side of the first conveyor belt 7 are rotatably connected to a drive shaft 15. One end of the drive shaft 15 extends to the inner side of the protective shell 11. The output end of the first drive motor 12 is fixedly connected to the drive shaft 15 near the collection roller 5. A transmission assembly is provided on the inner side of the protective shell 11.
[0033] The transmission assembly includes a second transmission belt group 14, which is located between the end of the collecting roller 5 located outside the fixed frame 4 and the transmission shaft 15. The collecting roller 5 is connected to the transmission shaft 15 through the second transmission belt group 14. A first transmission belt group 13 is provided at the end of the two transmission shafts 15 near the first drive motor 12, and the two transmission shafts 15 are connected to each other through the first transmission belt group 13.
[0034] When the collecting roller 5 contacts the ground, the first drive motor 12 is started, which drives the transmission shaft 15 to rotate. When the transmission shaft 15 rotates, the first transmission belt group 13 and the second transmission belt group 14 drive the collecting roller 5 and the first conveyor belt 7 to rotate and transport simultaneously. When the collecting roller 5 rotates, it pushes the shells on the ground to the top of the first conveyor belt 7. The baffles evenly arranged on the outside of the first conveyor belt 7 can effectively prevent the shells from falling. Then, the shells or other impurities are transported to the top of the second conveyor belt 17 by the first conveyor belt 7, thus completing the shell picking work.
