[0013] (1) Using the transport box, handle, top cover, push rod one, push plate one, spring one, bottom cover, push rod two, push plate two, and spring two, push plate one first drives the two push rods one to slide inside the transport box, thereby pushing the top cover to slide and one end to slide out of the transport box. At this time, the placement box containing the air separator body is slid into the transport box and the lower surface of the placement box contacts the upper surface of the bottom cover. Then, push plate one is released, and spring one drives push plate one to reset, causing push rod one to drive the top cover to slide and reset. The top cover covers the placement box. Place the upper surface of the container, then rotate the handle to move the container, moving the container containing the container and the air separator to the blast hole. Position the lower surface of the container directly above the blast hole, then push the push plate two to slide the two push rods two, causing the bottom cover to slide inside the container and one end to be placed outside the container.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0026] Example 1:

[0027] Depend on Figures 1-3 As shown, this utility model provides a convenient air separator, including a transport box 1. A handle 101 is movably connected to the outer wall of the transport box 1, and the handle 101 is limited to rotating on the outer wall of the transport box 1. A top cover assembly 2 and a bottom cover assembly 3 are installed inside the transport box 1. The top cover assembly 2 is installed at the upper part of the interior of the transport box 1, and the bottom cover assembly 3 is installed at the lower part of the interior of the transport box 1. The top cover assembly 2 includes a top cover plate 201, and the bottom cover assembly 3 includes a bottom cover plate 301. A placement box 4 is placed between the top cover plate 201 and the bottom cover plate 301. Four air separator bodies 5 are placed inside the placement box 4. The top cover plate 201 is slidably connected to the interior of the transport box 1, and the top cover plate 201 is limited to sliding inside the interior of the transport box 1. Push rods 202 are fixedly connected to both sides of the outer wall of the top cover plate 201. The push rod 202 slides inside the transport box 1. The outer wall of the push rod 202 is fixedly connected to the push plate 203. The outer wall of the push rod 202 is fitted with the spring 204. The bottom cover plate 301 is slidably connected inside the transport box 1. The bottom cover plate 301 is limited to slide inside the transport box 1. The two sides of the outer wall of the bottom cover plate 301 are fixedly connected to the push rod 202. The push rod 202 slides inside the transport box 1. The outer wall of the push rod 202 is fixedly connected to the push plate 203. The outer wall of the push rod 202 is fitted with the spring 204. The lower surface of the top cover plate 201 is in contact with the upper surface of the placement box 4. The upper surface of the bottom cover plate 301 is in contact with the lower surface of the placement box 4. The two ends of the spring 204 are fixed to the push plate 203 and the inside of the transport box 1, respectively. The two ends of the spring 204 are fixed to the push plate 203 and the inside of the transport box 1, respectively.

[0028] Working principle: When the placement box 4 needs to be transported and delivered to the blast hole, push plate 203 is first pushed, causing push plate 203 to push two push rods 202 to move to the left and slide inside the transport box 1. Spring 204 is compressed by the movement of push plate 203. At this time, top cover plate 201 slides to the left and one end is placed outside the transport box 1. After top cover plate 201 is fully opened, the placement box 4 containing the air separator body 5 can be slidably placed inside the transport box 1. The lower surface of the placement box 4 contacts the upper surface of the bottom cover plate 301. Then, the push plate 203 is released, and the compressed spring 204 drives the push plate 203 to reset, causing the push rod 202 to drive the top cover plate 201 to reset. After the top cover plate 201 resets, it covers the upper surface of the placement box 4. Then, the handle 101 is rotated to make it vertical. The handle 101 drives the transport box 1 to move, which in turn drives the placement box 4 to move, transporting the placement box 4 to the location of the blast hole. The lower surface of box 1 is positioned directly above the blast hole. Pushing push plate 303 causes push rod 302 to slide to the left, sliding bottom cover 301. This causes one end of bottom cover 301 to be positioned outside transport box 1. Spring 304 is compressed by the movement of push plate 303. After bottom cover 301 is fully pushed open, box 4 slides vertically downwards out of transport box 1 and into the blast hole. Then, push plate 303 is released, causing spring 304 to move push plate 303 and push rod 302... 302 is reset so that the bottom cover 301 is reset and placed inside the lower part of the transport box 1. Through the above solution, not only can the placement box 4 be prevented from falling during transport, but the placement box 4 can also be quickly transported to the inside of the blast hole. Even if the push plate 1 203 or the push plate 2 303 is accidentally touched, it will only move a short distance and will not cause the top cover 201 or the bottom cover 301 to open completely, thereby preventing the placement box 4 from falling during transport and causing damage to the air separator body 5.

[0029] Example 2:

[0030] Depend on Figures 3-8As shown, this utility model provides a convenient air gap. The transport box 1 has a sliding groove 102 inside. A spring 405 is installed inside the placement box 4. Both ends of the spring 405 are fixedly connected to a sliding rod 402. The sliding rod 402 is slidably connected inside the placement box 4, and its sliding position is limited within the placement box 4. A connecting block 403 is fixedly connected to the outer wall of the sliding rod 402, and its sliding position is limited within the placement box 4. A roller 404 is movably connected inside the connecting block 403. The outer wall of the roller 404 is in contact with the inner wall of the sliding groove 102. The connecting block 403 and the roller 404 are limited to sliding within the sliding groove 102. The spring 405 supports the sliding rod 402, causing the outer wall of the roller 404 to contact the inner wall of the sliding groove 102. 2. The inner wall is fitted. The interior of the placement box 4 is fixedly connected with three partitions 401. The three partitions 401 are used to separate four air separator bodies 5. The three partitions 401 divide the space inside the placement box 4 into four areas. Two larger air separator bodies 5 and two smaller air separator bodies 5 can be placed. The number of air separator bodies 5 can be selected according to actual usage needs. The interior of the air separator body 5 is slidably connected with a locking pin 501. The locking pin 501 is limited to slide inside the air separator body 5. The locking pin 501 is slidably connected inside the placement box 4. The locking pin 501 is limited to be locked inside the placement box 4. The interior of the air separator body 5 is provided with a spring 4 502. The two ends of the spring 4 502 are fixed to the locking pin 501 and the interior of the air separator body 5 respectively.

[0031] Working principle: When the air separator body 5 is placed inside the placement box 4, the air separator body 5 is pushed into the placement box 4. At this time, the locking pin 501 is squeezed by the inner wall of the placement box 4 and slides into the air separator body 5. When the locking pin 501 slides to the corresponding position inside the placement box 4, the spring 4 502 supports the locking pin 501, causing the locking pin 501 to be locked inside the placement box 4, thereby limiting and fixing the air separator body 5 inside the placement box 4. When the placement box 4 is placed inside the transport box 1... When the roller 404 is pressed by the inner wall of the slide groove 102, it slides into the placement box 4 and pushes the slide rod 402 to compress the spring 405. Thus, the roller 404 is supported by the inner wall of the slide groove 102. Using the same principle, when the placement box 4 enters the blast hole, the roller 404 is pressed by the inner wall of the blast hole. After being pressed, the roller 404 pushes the connecting block 403 and the slide rod 402 to slide and compresses the spring 405. This causes the roller 404 to be supported by the inner wall of the blast hole when the placement box 4 slides inside the blast hole.
