SUMMARY

[0005] In view of the deficiencies of the prior art, the present application provides a phosphorite mining underground air dust removal equipment to solve the problems raised in the background art.

[0006] To achieve the above purpose, the present application is implemented by the following technical scheme: a phosphorite mining underground air dust removal equipment, comprising a bottom plate, a convenient device for multi-directional movement, the convenient device further comprising;

[0007] a track fixedly installed on the top of the bottom plate, a load plate slidingly installed on the top of the track, and a fog cannon rotatably installed on the top of the load plate;

[0008] The elastic telescopic column has a fixed end fixedly installed on the bottom of a base plate. A fixing plate is fixedly installed on the front of the fixed end of the elastic telescopic column. One end of a long rod is fixedly installed on the bottom of the fixing plate, and a sealing plate is fixedly installed on the other end of the long rod. A square box is fixedly installed on the front of the free end of the elastic telescopic column. The square box has a round hole on its front. The square box is used to control the descent speed of the base plate at the top of the elastic telescopic column. When it is necessary to spray dust suppression in multiple directions, the carrier plate is moved on the track. When the carrier plate moves, it will contact the square block. When the carrier plate contacts the square block, the movement of the carrier plate will drive the square block to move.

[0009] According to the above technical solution, the convenient device further includes a rotating plate, a block, a locking rod, an elastic telescopic locking plate, and an L-rod. The rotating plate is rotatably mounted on the left side of the base plate, the locking rod is slidably mounted on the front of the track, the block is rotatably mounted on the front of the locking rod, the L-rod is slidably mounted on the front of the base plate, and the elastic telescopic locking plate is fixedly mounted on the fixed end of the elastic telescopic column. When the free end of the elastic telescopic locking plate moves, it will release the restriction on the elastic telescopic column. When the restriction on the elastic telescopic column is released, the free end of the elastic telescopic column will move.

[0010] According to the above technical solution, the block is in contact with the carrier plate, a spring is provided between the rotating plate and the base plate, and the L rod is in contact with the rotating plate;

[0011] The bottom of the base plate is equipped with a support device to prevent the ground from sinking due to the spraying of the sprayer on muddy ground, and a buffer device to prevent the rotating plate from flipping directly downwards and damaging the bottom support in case of a malfunction. When the long bar moves, it will drive the sealing plate to move inside the square box. When the sealing plate moves inside the square box, the number of holes between the sealing plate and the square box will continuously decrease.

[0012] According to the above technical solution, the support device includes a slider, an irregular rod, a round rod, a square column, and an L-block. The slider is slidably installed on the inner wall of the square box. One end of the irregular rod is fixedly installed on the top of the slider, and the round rod is fixedly installed on the other end of the irregular rod. The square column is rotatably installed inside the bottom of the elastic telescopic column. The L-block is fixedly installed on the side of the square column away from the slider. When the irregular rod moves, it will drive the round rod to move. When the round rod moves, it will contact the L-block on the square column. When the round rod contacts the L-block, it will cause the L-block to rotate.

[0013] According to the above technical solution, the support device further includes a connecting plate, an elastic telescopic column, a circular ring, an inner ring, a strip block, a circular frame, a rotating strip plate, and a rotating plate. One end of the connecting plate is fixedly installed on the right side of the irregular rod, and the circular ring is fixedly installed on the other end of the connecting plate. The fixed end of the elastic telescopic column is fixedly installed on the bottom of the base plate. The strip block is fixedly installed on the circumferential surface of the free end of the elastic telescopic column. The circular frame is fixedly installed at the bottom of the free end of the elastic telescopic column. The rotating plate is rotatably installed inside the circular frame. The rotating strip plate is rotatably installed on the bottom of the inner wall of the circular frame. The inner ring is slidably installed on the circumferential surface of the circular frame. When the two continue to press, the strip block will press the inner ring inside the circular ring downwards. When the inner ring and the circular ring move to contact the strip block, the limiting position on the rotating strip plate on the circular frame will be released.

[0014] According to the above technical solution, the inner ring is in contact with the rotating plate, the inner ring is in contact with the rotating bar plate, and the bar block is in contact with the inner ring. When the limiting position of the rotating bar plate is released, the rotating bar plate rotates downward, and when the inner ring moves to the bottom, it will contact one end of the rotating plate, thereby causing the other end of the rotating plate to flip to the top of the inner ring.

[0015] According to the above technical solution, the buffer device includes a cuboid, a connecting rod, a top plate, a baffle, an elastic telescopic block, a rectangular block, and an elastic telescopic buffer plate. The cuboid is fixedly installed inside the connecting plate. One end of the connecting rod is fixedly installed on the top of the cuboid. The top plate is fixedly installed on the top of the other end of the connecting rod. The baffle is slidably installed on the top of the top plate. The fixed end of the elastic telescopic block is fixedly installed on the bottom of the bottom plate. The rectangular block is fixedly installed on the free end of the elastic telescopic block. The elastic telescopic buffer plate is fixedly installed on the side of the rectangular block away from the elastic telescopic block. When the connecting rod moves, it will drive the top plate to move. When the top plate moves, it will drive the baffle to move. When the baffle moves, it will release the restriction on the elastic telescopic block.

[0016] According to the above technical solution, the baffle is in contact with the elastic telescopic block, and the rotating plate is in contact with the elastic telescopic buffer plate. When the rotating plate is in contact with the elastic telescopic buffer plate, it will be buffered by the elasticity provided by the elastic telescopic buffer plate, and when the rotating plate moves to the bottom, it will also compress the elastic telescopic block.

[0017] This invention provides an underground air dust removal device for phosphate mining. It has the following beneficial effects:

[0018] (1) In this invention, when the sealing plate moves inside the box, the number of holes between the two is reduced. The throttling effect of the holes is used to slow down the descent speed of the elastic telescopic column, so as to avoid the elastic telescopic column falling too fast and causing the sprayer height to deviate from the preset requirements. This ensures that the sprayer is always at the optimal dust removal height. As the range of motion of the sprayer expands with the carrier plate, it can achieve multi-directional and wider area spraying and dust removal. This solves the problem of incomplete dust removal in a single fixed range when the underground space is complex, and improves the comprehensiveness and flexibility of dust removal.

[0019] (2) This invention increases the support points and structural strength of the bottom of the elastic telescopic column by rotating and unfolding the square column, avoiding the tilting and shaking of the elastic telescopic column caused by uneven ground, the weight of the equipment itself or vibration during spraying operations. The inner ring triggers the rotating plate to flip and limit the position, so that the rotating bar plate at the bottom of the round frame forms a "diffusion support surface". The unfolding of the rotating bar plate greatly increases the contact area between the bottom plate and the ground, reduces the pressure of the equipment on the ground, effectively prevents the equipment from sinking into the mud pit due to insufficient ground bearing capacity, ensures that the equipment can still move and operate normally in complex underground environments, and improves the adaptability of the equipment to working conditions.

[0020] (3) When the cuboid moves upward, it drives the baffle to be fixed to the bottom of the base plate and limits the elastic telescopic block to ensure that the rotating plate is stably in contact with the elastic telescopic buffer plate when it flips. When buffering is needed, the limit can be released to activate the buffer function. When the rotating plate flips downward, it first contacts the elastic telescopic buffer plate. Its elasticity can buffer the impact. The bottom compressed elastic telescopic block further unloads the force, avoiding the rotating plate from directly hitting the elastic telescopic column, reducing the collision and wear of parts, extending the service life of the equipment, and reducing the downhole maintenance cost.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-7 One embodiment of the present invention is: an underground air dust removal device for phosphate mining, including a base plate 1, a convenient device for multi-directional movement, and the convenient device further includes;

[0031] Track 402 is fixedly installed on the top of base plate 1. Carrier plate 2 is slidably installed on the top of track 402. Sprayer 3 is rotatably installed on the top of carrier plate 2.

[0032] The elastic telescopic column 405 has its fixed end fixedly installed at the bottom of the base plate 1. A fixing plate 406 is fixedly installed on the front of the fixed end of the elastic telescopic column 405. One end of a long rod 407 is fixedly installed at the bottom of the fixing plate 406, and a sealing plate 408 is fixedly installed at the other end of the long rod 407. A square box 409 is fixedly installed on the front of the free end of the elastic telescopic column 405. A round hole is opened on the front of the square box 409. The square box 409 is used to control the descent speed of the base plate 1 at the top of the elastic telescopic column 405, ensuring that the sprayer 3 is always at the optimal dust removal height. As the range of motion of the carrier plate 2 expands, the sprayer 3 can achieve multi-directional and wider-area dust suppression, solving the problem of incomplete dust removal in a single fixed range when the underground space is complex, and improving the comprehensiveness and flexibility of dust removal.

[0033] The convenient device also includes a rotating plate 401, a block 403, a locking rod 404, an elastic telescopic locking plate 410, and an L-rod 411. The rotating plate 401 is rotatably mounted on the left side of the base plate 1. The locking rod 404 is slidably mounted on the front of the track 402. The block 403 is rotatably mounted on the front of the locking rod 404. The L-rod 411 is slidably mounted on the front of the base plate 1. The elastic telescopic locking plate 410 is fixedly mounted on the fixed end of the elastic telescopic column 405. When the free end of the elastic telescopic locking plate 410 moves, it will release the limit on the elastic telescopic column 405. When the limit on the elastic telescopic column 405 is released, the free end of the elastic telescopic column 405 will move.

[0034] The block 403 is in contact with the carrier plate 2. A spring is provided between the rotating plate 401 and the base plate 1. The L rod 411 is in contact with the rotating plate 401. When the long rod 407 moves, it will drive the sealing plate 408 to move inside the box 409. When the sealing plate 408 moves inside the box 409, the number of holes between the sealing plate 408 and the box 409 will continuously decrease.

[0035] In this embodiment, when the L-bar 411 is pulled, the limiting position on the rotating plate 401 is released when the L-bar 411 moves. When the limiting position on the rotating plate 401 is released, the end of the rotating plate 401 away from the base plate 1 will flip upward, so that the rotating plate 401 and the base plate 1 become a horizontal plane. When it is necessary to spray dust suppression in multiple directions, the carrier plate 2 is moved on the track 402. When the carrier plate 2 moves, it will contact the block 403. When the carrier plate 2 contacts the block 403, the moving of the carrier plate 2 will drive the block 403 to move. When the block 403 moves, it will drive the locking rod 404 to move.

[0036] When the lever 404 moves, it will limit the movement between the rotating plate 401 and the base plate 1, thereby increasing the range of motion of the carrier plate 2. The sprayer 3 is turned on to spray and reduce dust in a specific area. The free end of the elastic telescopic plate 410 on the elastic telescopic column 405 is moved. When the free end of the elastic telescopic plate 410 moves, it will release the limit on the elastic telescopic column 405. When the limit on the elastic telescopic column 405 is released, the free end of the elastic telescopic column 405 will move. When the free end of the elastic telescopic column 405 moves, it will drive the fixed plate 406 to move.

[0037] When the fixed plate 406 moves, it will drive the long bar 407 to move. When the long bar 407 moves, it will drive the sealing plate 408 to move inside the square box 409. When the sealing plate 408 moves inside the square box 409, the number of holes between the sealing plate 408 and the square box 409 will continuously decrease, thereby slowing down the descent speed of the sealing plate 408. This prevents the elastic telescopic column 405 from descending too quickly and failing to effectively maintain the required height of the sprayer 3.

[0038] Please see Figures 1-7 Based on the above embodiments, in another embodiment of the present invention, the bottom of the base plate 1 is provided with a support device to prevent the ground from sinking due to the spraying of the sprayer 3 in muddy ground, and a buffer device to prevent the rotating plate 401 from directly flipping downwards and damaging the bottom support when it malfunctions. The support device includes a slider 501, an irregular rod 502, a round rod 503, a square column 504 and an L-block 505. The slider 501 is slidably installed on the inner wall of the square box 409. One end of the irregular rod 502 is fixedly installed on the top of the slider 501. The round rod 503 is fixedly installed on the other end of the irregular rod 502. The square column 504 is rotatably installed inside the bottom of the elastic telescopic column 405. The L-block 505 is fixedly installed on the side of the square column 504 away from the slider 501. The unfolding of the rotating plate 512 greatly increases the contact area between the base plate 1 and the ground, reduces the pressure of the equipment on the ground, effectively prevents the equipment from sinking into the mud pit due to insufficient ground bearing capacity, ensures that the equipment can still move and operate normally in complex underground environments, and improves the adaptability of the equipment to working conditions.

[0039] The support device also includes a connecting plate 506, an elastic telescopic column 507, a ring 508, an inner ring 509, a strip 510, a circular frame 511, a rotating plate 512, and a rotating plate 513. One end of the connecting plate 506 is fixedly installed on the right side of the irregular rod 502, the ring 508 is fixedly installed on the other end of the connecting plate 506, the fixed end of the elastic telescopic column 507 is fixedly installed on the bottom of the base plate 1, the strip 510 is fixedly installed on the circumferential surface of the free end of the elastic telescopic column 507, and the circular frame 511... 1. Fixedly installed at the bottom of the free end of the elastic telescopic column 507, the rotating plate 513 is rotatably installed inside the circular frame 511, the rotating strip plate 512 is rotatably installed at the bottom of the inner wall of the circular frame 511, and the inner ring 509 is slidably installed on the circumferential surface of the circular frame 511. When the two continue to press, the strip 510 will press the inner ring 509 inside the circular ring 508 downward. When the inner ring 509 and the circular ring 508 move to contact the strip 510, the limiting of the rotating strip plate 512 on the circular frame 511 will be released.

[0040] The inner ring 509 contacts the rotating plate 513, the inner ring 509 contacts the rotating bar plate 512, and the bar block 510 contacts the inner ring 509. When the limit of the rotating bar plate 512 is released, the rotating bar plate 512 rotates downward, and when the inner ring 509 moves to the bottom, it will contact one end of the rotating plate 513, thereby causing the other end of the rotating plate 513 to flip to the top of the inner ring 509.

[0041] The buffer device includes a cuboid 601, a connecting rod 602, a top plate 603, a baffle 604, an elastic telescopic block 605, a rectangular block 606, and an elastic telescopic buffer plate 607. The cuboid 601 is fixedly installed inside the connecting plate 506. One end of the connecting rod 602 is fixedly installed on the top of the cuboid 601. The top plate 603 is fixedly installed on the top of the other end of the connecting rod 602. The baffle 604 is slidably installed on the top of the top plate 603. The fixed end of the elastic telescopic block 605 is fixedly installed on the bottom of the base plate 1. The rectangular block 606 is fixedly installed on the free end of the elastic telescopic block 605. The elastic telescopic buffer plate 607 is fixedly installed on the side of the rectangular block 606 away from the elastic telescopic block 605. The elasticity can buffer the impact, and the bottom compression of the elastic telescopic block 605 further dissipates the force, preventing the rotating plate 401 from directly hitting the elastic telescopic column 405, reducing component collision wear, extending equipment service life, and reducing downhole maintenance costs.

[0042] The baffle 604 contacts the elastic telescopic block 605, and the rotating plate 401 contacts the elastic telescopic buffer plate 607. When the rotating plate 401 contacts the elastic telescopic buffer plate 607, it will be buffered by the elasticity provided by the elastic telescopic buffer plate 607. When the rotating plate 401 moves to the bottom, it will also compress the elastic telescopic block 605.

[0043] In this embodiment, when the sealing plate 408 moves upward, it will drive the slider 501 to move. When the slider 501 moves, it will drive the irregular rod 502 to move. When the irregular rod 502 moves, it will drive the round rod 503 to move. When the round rod 503 moves, it will contact the L block 505 on the square column 504. When the round rod 503 contacts the L block 505, it will cause the L block 505 to rotate. When the L block 505 rotates, it will drive the square column 504 to rotate, thereby making the support of the elastic telescopic column 405 more robust.

[0044] When the irregular rod 502 moves, it will drive the connecting plate 506 to move. When the connecting plate 506 moves, it will drive the ring 508 to move. When the ring 508 moves, it will drive the inner ring 509 to move. When the inner ring 509 moves, it will contact the strip 510 at the free end of the elastic telescopic column 507. When the two continue to press, the strip 510 will press the inner ring 509 inside the ring 508 downward. When the inner ring 509 and the ring 508 move to contact the strip 510, the limit on the rotating strip plate 512 on the circular frame 511 will be released.

[0045] When the limit of the rotating plate 512 is released, the rotating plate 512 rotates downward, and when the inner ring 509 moves to the bottom, it will contact one end of the rotating plate 513, thereby causing the other end of the rotating plate 513 to flip to the top of the inner ring 509, limiting the inner ring 509, thereby increasing the contact area between the bottom plate 1 and the ground and preventing it from sinking into the mud pit.

[0046] When the connecting plate 506 moves, it will drive the cuboid 601 to move. When the cuboid 601 moves, it will drive the connecting rod 602 to move. When the connecting rod 602 moves, it will drive the top plate 603 to move. When the top plate 603 moves, it will drive the baffle 604 to move. When the baffle 604 moves, it will release the limit on the elastic telescopic block 605. When the limit on the elastic telescopic block 605 is released, the rotating plate 401 will flip downward and contact the elastic telescopic buffer plate 607 on the cuboid 606.

[0047] When the rotating plate 401 comes into contact with the elastic telescopic buffer plate 607, it will be buffered by the elasticity provided by the elastic telescopic buffer plate 607. When the rotating plate 401 moves to the bottom, it will also compress the elastic telescopic block 605, so that the rotating plate 401 moves completely to the bottom. However, when the cuboid 601 moves upward, it will drive the baffle 604 to move upward.

[0048] This fixes the baffle 604 to the bottom of the base plate 1, thereby limiting the elastic telescopic block 605. When the rotating plate 401 flips downward, it will temporarily come into complete contact with the elastic telescopic buffer plate 607, instead of directly contacting the elastic telescopic column 405 and causing collision damage.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
