Abstract
Description
Technical Field
[0001] This utility model belongs to the field of projectile loading technology, specifically relating to a precise projectile loading and weighing system. Background Technology
[0002] In the military projectile assembly process, the addition of propellant in the anti-riot chamber is a crucial and bottleneck step. Currently, some projectile propellant addition operations still rely on manual experience for dosage control. During manual operation, due to individual differences among operators, such as subtle differences in visual judgment and operating techniques, it is difficult to maintain a high degree of consistency in the amount of propellant added each time. This deviation in the amount of propellant added due to human factors can cause fluctuations in projectile performance. On the other hand, excessive propellant addition may cause safety issues during the use of the projectile. The propellants added to the projectile are often flammable, explosive, toxic, and harmful. During manual addition, operators inevitably come into direct contact with these dangerous agents. Slight carelessness, such as agent leakage, friction or collision caused by improper operation, can lead to serious safety accidents. Utility Model Content

Detailed Implementation
[0020] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.
[0021] Example 1, as Figure 1 , Figure 2 and Figure 3 As shown, a precision propellant weighing system for projectiles includes a projectile weighing device 2 installed on the inner bottom of a frame 1, a propellant weighing and dispensing device 3 installed on the top of the frame 1, an assembly frame 4 installed at the output end of the propellant weighing and dispensing device 3, the assembly frame 4 being fixedly installed on the top of the frame 1, an assembly plate 5 installed on the assembly frame 4, a funnel 6 installed on the assembly plate 5, the funnel 6 being located below the output end of the propellant weighing and dispensing device 3, a protective cover 7 installed on the outer top of the frame 1, and the propellant weighing and dispensing device 3 being located inside the protective cover 7.
[0022] In this embodiment, during use, when the conveyor line drives the tray, and the tray drives the projectile to move into the frame 1, the projectile weighing device 2 is activated, pushing the projectile out of the tray. The bottom of the projectile falls directly onto the projectile weighing device 2. The projectile weighing device 2 pushes the projectile to move and aligns the projectile's nozzle with the funnel 6. Then, the agent weighing and adding device 3 performs the weighing and adding process. The weighed agent reaches the inside of the projectile through the funnel 6. After the projectile is loaded with the agent, it is weighed again by the projectile weighing device 2, thereby improving the accuracy of the adding process.
[0023] Example 2, as Figure 5As shown, this embodiment adds the following structure based on embodiment 1: the projectile weighing device 2 includes a mounting base 8 installed at the bottom of the frame 1. The mounting base 8 is U-shaped. A drive cylinder 9 is installed inside the mounting base 8. The power output end of the drive cylinder 9 is connected to a transverse frame 10. A slider 11 is installed at the bottom of the transverse frame 10. The slider 11 is slidably connected to a slide rail 12. The slide rail 12 is installed on both sides of the top of the mounting base 8. A lifting cylinder 13 is installed at the top of the transverse frame 10. The power output end of the lifting cylinder 13 is connected to a lifting plate 14. An explosion-proof electronic scale 15 is installed at the top of the lifting plate 14. A support block 16 is installed at the top of the explosion-proof electronic scale 15. Guide rods 17 are installed on the four sides of the bottom of the lifting plate 14. T-shaped guide sleeves 18 are slidably connected to the guide rods 17. The T-shaped guide sleeves 18 are fixedly installed on the top of the transverse frame 10.
[0024] In this embodiment, during use, the lifting cylinder 13 is activated, causing it to push the lifting plate 14. The lifting plate 14 then pushes the explosion-proof electronic scale 15, which in turn moves the support block 16 upwards. During the movement of the lifting plate 14, the guide rod 17 slides along the T-shaped guide sleeve 18, thereby improving the stability of the lifting plate 14 during movement. When the top of the support block 16 contacts the projectile, the projectile is pushed out of the projectile's placement tray, and the bottom of the projectile lands directly on the support block 16 on the explosion-proof electronic scale 15. After lifting... The drive cylinder 9 is activated, which pushes the transverse frame 10. The transverse frame 10 drives the lifting cylinder 13, which in turn drives the lifting plate 14. The lifting plate 14 drives the explosion-proof electronic scale 15, which in turn drives the support block 16. The support block 16 drives the projectile to move laterally, so that the projectile's nozzle aligns with the funnel 6, thus facilitating subsequent loading. When the drive cylinder 9 pushes the transverse frame 10 to move laterally, the transverse frame 10 will cause the bottom slider 11 to slide along the slide rail 12, ensuring the stability of the transverse frame 10 during lateral movement.
[0025] Example 3, as Figure 2 and Figure 3 As shown, this embodiment adds the following structure based on embodiment 1: the drug weighing and dosing device 3 includes a coarse dosing mechanism 19 and a fine dosing mechanism 20. The coarse dosing mechanism 19 is located on the right side of the frame 1, and the fine dosing mechanism 20 is located on the left side of the frame 1. A weighing and feeding assembly 21 is installed on the frame 1 at the output end of the coarse dosing mechanism 19 and the fine dosing mechanism 20.
[0026] In this embodiment, during use, coarse dosing is performed by the coarse dosing mechanism 19. The coarse dosing agent falls onto the weighing and feeding assembly 21, which weighs it and pours it into the funnel 6. After the coarse dosing mechanism 19 completes the dosing, the fine dosing mechanism 20 delivers a trace amount of agent to the weighing and feeding assembly 21, which weighs it until the amount of agent added reaches the required weight. Then, the fine dosing mechanism 20 stops delivering the agent, and the weighing and feeding assembly 21 pours the agent into the funnel 6, completing the dosing process.
[0027] Example 4, as Figure 4 As shown, this embodiment adds the following structure based on embodiment 3: the coarse dosing mechanism 19 includes a support frame 22 installed on the top of the frame 1, a feeding bin 23 installed on the top of the support frame 22, a feeding block 24 slidably installed in the feeding bin 23, a drug storage channel 25 provided in the feeding block 24, a cylinder 26 installed on the outer side of the feeding bin 23, the power output end of the cylinder 26 being connected to the feeding block 24, a coarse dosing hopper 27 installed on the top side of the feeding bin 23, and a coarse dosing nozzle 28 installed on the bottom side of the feeding bin 23.
[0028] In this embodiment, during the crude dosing operation, the agent is fed from the crude dosing hopper 27 into the storage channel 25 inside the loading block 24. After the storage channel 25 is full, the cylinder 26 is activated, causing the cylinder 26 to push the loading block 24 to slide within the discharge bin 23. This causes the loading block 24 to move from the bottom of the crude dosing hopper 27 to the top of the crude dosing nozzle 28. When the loading block 24 moves to the crude dosing nozzle 28, the agent in the storage channel 25 falls into the crude dosing nozzle 28 and is output from the crude dosing nozzle 28 to the weighing and dispensing assembly 21. The weighing and dispensing assembly 21 weighs and detects the amount of crude dosing, enabling the crude dosing to be completed in multiple batches for dosing and weighing. After weighing, the weighing and dispensing assembly 21 pours the agent into the funnel 6.
[0029] Example 5, as Figure 4 As shown, this embodiment adds the following structure based on embodiment 3: the fine dosing mechanism 20 includes a fixed frame 29 installed on one side of the top of the frame 1, a fine dosing hopper 30 installed on the top of the fixed frame 29, a conveying bin 31 provided at the bottom output end of the fine dosing hopper 30, and a linear vibration device 32 installed at the bottom of the conveying bin 31. The linear vibration device 32 is installed on the frame 1.
[0030] In this embodiment, during fine dosing, the agent is fed from the fine dosing hopper 30 to the conveying hopper 31. At the same time, the linear vibration device 32 is activated, so that the conveying hopper 31 conveys the trace amount of agent to the weighing and discharging assembly 21 through the linear vibration device 32. The agent is conveyed until the amount of agent added in each batch reaches the weight requirement, and then the fine dosing weighing mechanism 4 stops conveying the agent.
[0031] Example 6, as Figure 4 As shown, this embodiment adds the following structure based on embodiment 3: the weighing and feeding assembly 21 includes a weighing base 33 installed on the top of the frame 1, a feeding box 34 hinged to the top of the weighing base 33, a feeding port 35 on one side of the feeding box 34, the feeding box 34 is located at the output end of the coarse dosing nozzle 28 and the conveying hopper 31 and is located below it, the feeding port 35 is located above the funnel 6, a precision weighing explosion-proof sensor 36 is installed on the top of the weighing base 33, the top of the precision weighing explosion-proof sensor 36 is in contact with the bottom of the feeding box 34, a pouring cylinder 37 is installed on the outer side of the top of the weighing base 33, the power output end of the pouring cylinder 37 is connected to a hinge seat 38, and the hinge seat 38 is slidably installed on the bottom of the feeding box 34.
[0032] In this embodiment, during use, the chemicals output from the coarse dosing nozzle 28 and the conveying hopper 31 both fall into the feeding box 34. After the chemicals fall into the feeding box 34, the precision weighing explosion-proof sensor 36 simultaneously performs precise weighing. Once the coarse and fine dosing amounts meet the weight requirements, the discharging cylinder 37 is activated. The discharging cylinder 37 pushes the hinge seat 38, which in turn tilts the feeding box 34, causing the chemicals in the feeding box 34 to flow out through the discharge port 35 and into the inlet funnel 6 for dosing. After tilting is complete, the feeding box 34 returns to its original position, ready for subsequent coarse or fine dosing operations.
[0033] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
