Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please see Figure 1-6This utility model provides a fire extinguishing agent production and feeding machine with a sealed structure, including a feeding box 1. A motor 2 is installed on the top wall of the feeding box 1. The output shaft of the motor 2 extends into the feeding box 1 and is fixedly connected to a transmission rod 21. An auger 22 is fixedly connected to the bottom end of the transmission rod 21. The output shaft of the motor 2 can drive the transmission rod 21 to rotate. When the transmission rod 21 rotates, it drives the auger 22 to rotate. The rotation of the auger 22 cooperates with the discharge cylinder 3 to discharge the agent. The bottom of the feeding box 1 is provided with a discharge cylinder 3. A boss 31 is fixedly connected to the lower side wall. A sealing groove 32 is provided on the lower side wall of the boss 31. A sealing ring is provided in the sealing groove 32. After the adapter cylinder 5 is installed, the lower inner wall of the adapter cylinder 5 will squeeze the sealing ring on the boss 31, so that the sealing ring fills the sealing groove 32 to ensure the sealing between the adapter cylinder 3 and the feed cylinder 3. A connecting flange 4 is provided below the feed cylinder 3. An adapter cylinder 5 is fixedly connected to the upper side wall of the connecting flange 4. The adapter cylinder 5 and the feed cylinder 3 are detachably connected. A snap-fit ​​mechanism 6 is provided on the feed cylinder 3.

[0025] Specifically, such as Figures 3 to 5 As shown, a fire extinguishing agent production and feeding machine with a sealed structure includes a locking mechanism 6 comprising a slot 61, a receiving groove 62, a locking block 63, a pull rod 64, a pull block 65, and a spring 66. Four slots 61 are arranged around the lower side wall of the feeding cylinder 3. A receiving groove 62 is formed on the side wall of the slots 61 away from the boss 31. A locking block 63 is slidably disposed within the receiving groove 62. A pull rod 64 is rotatably connected to the side wall of the locking block 63 away from the boss 31. The other end of the pull rod 64 extends to the outside of the feeding cylinder 3 and is fixedly connected to the pull block 65. A spring 66 is disposed between the locking block 63 and the side wall of the receiving groove 62 away from the slot 61. When replacing the connecting flange 4, pulling the pull block 65 causes the pull rod 64 to pull the locking block 63 into the receiving groove 62. At this time, the spring 66 is compressed by the locking block 63. Then, the pull block 65 is rotated. Rotating the pull rod 64 causes the limit rod 641 to limit the locking block 63, preventing it from resetting. Then, pull the remaining pull blocks 65 one by one until all the locking blocks 63 retract into the receiving groove 62. Then, the adapter tube 5 and connecting flange 4 can be removed. When installing the connecting flange 4, insert the buckle 51 on the adapter tube 5 into the slot 61. Then, rotate the pull blocks 65 one by one until the limit rod 64 on the pull rod 64 aligns with the through port 71, allowing the limit rod 641 to pass through the through port 71. After releasing the limit on the locking block 63, the locking block 63 enters the slot 61 under the push of the spring 66, fixing the buckle 51 in the slot 61, thereby fixing the adapter tube 5. This allows for quick replacement of the connecting flange 4 according to the feed port size of different production equipment, making it suitable for various production equipment and more practical.

[0026] Specifically, such as Figure 6 As shown, a fire extinguishing agent production and feeding machine with a sealed structure has four buckles 51 on the upper side wall of the adapter cylinder 5 that are compatible with the locking block 63.

[0027] Specifically, such as Figure 5 As shown, a fire extinguishing agent production and feeding machine with a sealed structure has two symmetrically distributed limiting rods 641 fixedly connected to the rod wall outside the feeding cylinder 3.

[0028] Specifically, such as Figure 5 As shown, a fire extinguishing agent production and feeding machine with a sealed structure has four limiting plates 7 circumferentially arranged on the outer wall of the feeding cylinder 3. The pull rod 64 is slidably engaged with the limiting plate 7. The limiting plate 7 has a passage 71 that allows the limiting rod 641 to pass through. After the limiting rod 641 passes through the passage 71, rotating the pull rod 64 can change the position of the limiting rod 641, preventing it from passing through the passage 71. This can limit the position of the locking block 63, making it convenient to pull the other pulling blocks 65.

[0029] Specifically, such as Figure 2 As shown, a fire extinguishing agent production and feeding machine with a sealed structure has two symmetrically distributed scrapers 23 fixedly connected to the lower end of the transmission rod 21. When the transmission rod 21 rotates, it can drive the two scrapers 23 to rotate. When the scrapers 23 rotate, they can scrape the inner wall of the feeding box 1 to avoid the raw materials from adhering to the inner wall of the feeding box 1 and causing waste.

[0030] It should be noted that this utility model is a fire extinguishing agent production and feeding machine with a sealed structure. When the connecting flange 4 does not match the flange size of the feed inlet of the production equipment, pulling the pull block 65 causes the pull rod 64 to pull the locking block 63 into the receiving groove 62. At this time, the spring 66 is compressed by the locking block 63. Then, rotating the pull block 65 drives the pull rod 64 to rotate, and the rotation of the pull rod 64 drives the limit rod 641 to rotate, so that the limit rod 641 cannot pass through the through port 71 on the limit plate 7, thereby limiting the locking block 63 and preventing it from resetting. Then, pulling the remaining pull blocks 65 one by one causes all the locking blocks 63 to retract into the receiving groove 62. After the buckle 51 is no longer blocked by the locking blocks 63, the adapter cylinder 5 and the connecting flange 4 can be removed, and then the corresponding size can be taken out. When installing the connecting flange 4, insert the buckle 51 on the adapter cylinder 5 into the slot 61, and then rotate the pull block 65 one by one so that the limiting rod 641 on the pull rod 64 is aligned with the through port 71, allowing the limiting rod 641 to pass through the through port 71. After releasing the limiting of the buckle 63, the buckle 63 enters the slot 61 under the push of the spring 66, fixing the buckle 51 in the slot 61, thereby fixing the adapter cylinder 5. The connecting flange 4 can be quickly replaced according to the feed port size of different production equipment, adapting to various production equipment and making it more practical. After fixing the adapter cylinder 5, the lower inner wall of the adapter cylinder 5 will squeeze the sealing ring on the boss 31, so that the sealing ring fills the sealing groove 32 to ensure the sealing between it and the feed cylinder 3.
