[0054] The above structure in the material conveying operation, first, the bullet material is poured into the loading plate 3 through the telescopic lining 5, as the bullet material increases, the loading plate 3 slowly compresses the pressure spring, and moves vertically downward under the guidance of the supporting column 22, the telescopic lining 5 moves with the loading plate 3, the telescopic lining 5 stretches downward to hold the bullet material; then, after the bullet material is poured, the loading plate 3 stops moving downward, the lifting assembly 4 is controlled to tighten the traction rope, the discharging door 33 rotates upward, the discharging door 33 is opened, the bullet material falls into the discharging end of the hopper 1; finally, after the discharging is completed, the lifting assembly 4 is controlled to loosen the traction rope, the discharging door 33 is closed and reset under the gravity of the discharging door 33 itself, and the loading plate 3 moves upward and resets to facilitate subsequent discharging operation.

Therefore, the loading plate 3 and the telescopic inner liner 5 moving therewith can move along the direction from the feeding end to the discharge end of the hopper 1 during the bullet material conveying process to reduce the falling height of the bullet material, thereby effectively ensuring the conveying efficiency and quality of the bullet material during the conveying process.

[0056] On the basis of the above embodiments, please refer to Figure 3 and Figure 4 The loading plate 3 is uniformly distributed with a plurality of support slide rod members 31 around the circumference, the inner wall of the hopper 1 is circumferentially provided with a plurality of sliding grooves 11, the plurality of sliding grooves 11 are one-to-one corresponding to the plurality of support slide rod members 31, and one end of the support slide rod member 31 is telescopically inserted into the loading plate 3 and the other end is slidably inserted into the sliding groove 11.

[0057] Specifically, the loading plate 3 is uniformly provided with a plurality of mounting holes 34 around the circumference, the inner wall of the hopper 1 is provided with a plurality of sliding grooves 11 along the direction from the feeding end to the discharge end of the hopper 1, the plurality of sliding grooves 11, the plurality of mounting holes 34 and the plurality of support slide rod members 31 are one-to-one corresponding, and one end of each support slide rod member 31 is telescopically inserted into the corresponding mounting hole 34 and the other end is inserted into the corresponding sliding groove 11. In this way, as the bullet material increases, the loading plate 3 moves downward, the support slide rod members 31 on the side of the loading plate 3 move downward along the sliding grooves 11 and simultaneously compress the support slide rod members 31 into the mounting holes 34. Among them, the support slide rod member 31 and the sliding groove 11 are in sliding cooperation, which can guide the movement of the loading plate 3, and the support slide rod member 31 supports the loading plate 3 to improve the structural stability of the loading plate 3 and ensure the smooth movement of the loading plate 3 along the inner wall of the loading plate 3. In addition, since the diameter of the hopper 1 gradually decreases from the feeding end to the discharge end, the support slide rod member 31 can be telescopically arranged between the side edge of the loading plate 3 and the inner wall of the hopper 1 to ensure the smooth movement of the loading plate 3 along the inner wall of the loading plate 3.

[0058] It should be noted that the number of sliding grooves 11, mounting holes 34 and support slide rod members 31 is not unique and can be selected according to the size of the hopper 1 and the loading plate 3 in actual application.

[0059] On the basis of the above embodiments, please refer to Figure 4 and Figure 5The support slide rod component 31 comprises a telescopic spring rod 311, a spring limiting piece 312 and a slide rod 313 connected with the telescopic spring rod 311.

The traction rope drives the discharge door 33 to rotate around the rotary pin 331. The discharge door 33 is opened to open the discharge port 32. The lifting assembly 4 loosens the traction rope. Under the action of the gravity of the discharge door 33 itself, the discharge door 33 reversely rotates around the rotary pin 331. The discharge door 33 is closed and reset to shield the discharge port 32. Therefore, by using the above structure, the discharge door 33 is conveniently rotated to facilitate the lifting and falling of the discharge door 33, thereby facilitating the accurate control of the opening and closing of the discharge door 33.

[0063] It should be noted that the number of the discharge port 32 and the discharge door 33 on the load plate 3 is not unique, and can be selected according to the size of the actual load plate 3.

[0072] In addition to the above-mentioned bullet material hopper conveying device, the present application also provides a bullet material hopper conveying method applied to the above-mentioned embodiments, which comprises:

[0073] Step S1, the bullet material is poured onto the loading plate, and as the bullet material increases, the loading plate moves downward, and at the same time, the telescopic lining is stretched downward;

[0074] Specifically, the bullet material is poured onto the loading plate 3 through the telescopic lining 5, as the bullet material increases, the loading plate 3 slowly compresses the pressure elastic member 6, and moves vertically downward under the guidance of the support column 22, the telescopic lining 5 is stretched with the loading plate 3, and each sliding rod 313 around the loading plate 3 moves downward along the corresponding sliding groove 11, and at the same time, the telescopic spring 314 is compressed.

[0075] Step S2, after the cartridge material is poured, the lifting assembly is controlled to tighten the traction rope, the discharge door is opened, and the discharge is performed.

[0076] Specifically, after the cartridge material is poured, the crank handle on the crank 42 is rotated to drive the rope winding wheel 41 to wind the traction rope, the traction rope pulls the rope ear 332, the discharge door 33 is opened, and the discharge is performed. The cartridge material falls into the discharge end of the hopper 1.

[0077] Step S3, after the discharge is completed, the lifting assembly is controlled to loosen the traction rope, the discharge door is reset, and the loading plate moves upward to reset.

[0078] Specifically, after the discharge is completed, the crank handle on the crank 42 is rotated in the opposite direction to drive the rope winding wheel 41 to loosen the traction rope.

[0079] As described above, during the above-mentioned cartridge material conveying process, the telescopic liner 5 is stretched with the loading plate 3, which holds the cartridge material and reduces the collision damage of the cartridge material with the inner wall of the hopper 1. In addition, the falling height of the cartridge material from the loading plate 3 to the discharge end is reduced, that is, the distance between the feeding port 53 of the telescopic liner 5 and the loading plate 3 is always relatively short. In addition, the downward movement of the loading plate 3 can reduce the falling height of the cartridge material from the loading plate 3 to the discharge end. Therefore, the loading plate 3 and the telescopic liner 5 moving together can move along the direction from the feeding end to the discharge end of the hopper 1 during the cartridge material conveying process, so as to reduce the falling height of the cartridge material and effectively ensure the conveying efficiency and quality of the cartridge material during the cartridge material conveying process.
