Description

Technical Field

[0001] The utility model belongs to the technical field of mine tunnel dust removal, in particular to a spray dust removal mechanism for an open-pit mine tunnel. Background Art

[0002] Dust pollution has always been a pressing issue in open-pit mining operations. Large amounts of dust not only pose a serious threat to miners' health but also have a negative impact on the surrounding environment. Traditional dust removal methods often have limited effectiveness and fail to meet increasingly stringent environmental protection requirements. With the continuous advancement of technology, spray dust removal technology has gradually become a key means of dust removal in open-pit mines. However, due to the dusty environment, the nozzles can become clogged over time. Furthermore, the nozzles are fixed at a height and can only be repaired by professionals using lifting tools. This is dangerous and costly, and does not meet people's expectations.

[0003] The Chinese patent with publication number CN219324026U discloses an open-pit mine spray dust removal mechanism, which drives the arc-shaped slide plate and the clamping column to move outward by pulling the connecting rod, so that the clamping column is disengaged from the clamping hole, thereby releasing the limit of the convex strip, and the plug-in column can be pulled out of the fixing seat, which is convenient for cleaning and maintenance of the plug-in column and the spray head. The disassembly is simple and convenient, and the cost of using lifting tools is saved. Through the setting of the spring, under the tension of the spring, the two arc-shaped slide plates tightly clamp the plug-in column, and the clamping column is firmly stuck in the clamping hole, thereby improving the fixing effect between the plug-in column and the fixing seat, and making the plug-in column installation more secure. However, in an environment such as an open-pit mine where there may be large vibrations, after long-term use, the spring may become fatigued and relaxed, resulting in an insufficiently firm connection between the plug-in column and the clamping hole, and the plug-in column may shake, affecting the stability and spraying effect of the sprinkler head.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an open-pit mine spray dust removal mechanism, which solves the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0007] A spray dust removal mechanism for an open-pit mine comprises: a base, a fixed block connected to the top of the base, a screw connected to the fixed block for rotation, a lifting rod connected to the screw, a connecting rod connected to the top of the lifting rod, a connecting rod connected to the top of the connecting rod, a nozzle connected to the side wall of the connecting block, a worm wheel connected to the middle and lower end of the screw, a worm connected to the side wall of the worm wheel, a rotating shaft connected to the front end of the worm, a fixing ring located on the surface of the lifting rod, and a fixing rod connected to the bottom end of the fixing ring.

[0008] Optionally, the nozzle surface is provided with a plurality of water spray holes and water mist holes, and the plurality of water spray holes and water mist holes are distributed in a ring shape on the nozzle surface.

[0009] Optionally, the top end of the connecting rod is spherical, the bottom end of the connecting block is provided with a spherical groove corresponding thereto, and the top end of the connecting rod is embedded in the spherical groove.

[0010] Optionally, a groove is provided on the inner wall of the fixing ring, the inner wall of the groove is arc-shaped, and the rolling ball is embedded in the arc-shaped groove.

[0011] Optionally, there are multiple rolling balls, and the rolling balls are against the outer wall of the lifting rod.

[0012] Optionally, the top end of the fixing rod is fixedly connected to the bottom end of the fixing ring, and the bottom end of the fixing rod is fixedly connected to the top end of the base.

[0013] Optionally, a threaded hole is provided at the bottom end of the lifting rod, and the screw rod is inserted into the threaded hole and threadedly connected to the lifting rod.

[0014] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described below at the same time:

[0015] By setting up a lifting rod and realizing the up and down movement of the lifting rod through the rotation of the screw rod, the nozzle can be adjusted to the optimal spraying position whether facing the dust at the top of the mine tunnel or the accumulated dust at a lower position, which greatly improves the pertinence and effectiveness of dust removal;

[0016] By setting up the connecting rod and the connecting block, and the spherical connection design of the connecting block and the connecting rod, the nozzle can rotate freely at multiple angles within a certain range.

[0017] By setting a fixing ring and a fixing rod, a stable support is provided for the lifting rod. The top of the fixing rod is fixedly connected to the bottom of the fixing ring, and the bottom end is fixedly connected to the top of the base, so that the lifting rod is firmly fixed to the base to prevent it from shaking or tilting during the up and down movement, thereby ensuring the stability of the spraying direction and effect of the sprinkler head.

DETAILED DESCRIPTION

[0028] The present invention will now be described in further detail with reference to the accompanying drawings.

[0029] See also Figure 1-5As shown, in this embodiment, a spray dust removal mechanism for an open-pit mine tunnel is provided, including: a base 1, a fixed block 2 is connected to the top of the base 1, a screw rod 11 is rotatably connected inside the fixed block 2, a lifting rod 3 is connected through the screw rod 11, the top of the lifting rod 3 is connected to a connecting rod 4, the top of the connecting rod 4 is connected to a connecting block 5, the side wall of the connecting block 5 is connected to a nozzle 6, the middle and lower end of the screw rod 11 is connected to a worm gear 13, the side wall of the worm gear 13 is connected to a worm 12, the front end of the worm 12 is connected to a rotating shaft 9, a fixing ring 7, which is located on the surface of the lifting rod 3, and the bottom end of the fixing ring 7 is connected to a fixing rod 8.

[0030] The base 1 provides a stable support foundation for the entire spray dust removal mechanism, ensuring that the mechanism can be firmly placed in the open-pit mine. The fixed block 2 plays the role of fixing the screw rod 11, while providing support for the rotation of the screw rod 11 and limiting its movement space. The rotation of the worm 12 drives the worm wheel 13 to rotate, and then the screw rod 11 rotates. The rotation of the screw rod 11 can drive the lifting rod 3 to move up and down along the screw rod 11, thereby adjusting the height of the nozzle 6 to adapt to different mine environments and spraying requirements. The connecting rod 4 connects the lifting rod 3 and the connecting block 5. At the same time, the angle of the nozzle 6 can be adjusted by adjusting the angle of the connecting block 5 to improve the dust removal effect. The fixing ring 7 is located on the surface of the lifting rod 3 and is fixedly connected to the base 1 through the fixing rod 8, which stabilizes the lifting rod 3 and prevents the lifting rod 3 from shaking or tilting during the up and down movement, thereby ensuring the stability of the spraying direction and effect of the nozzle 6.

[0031] In this embodiment, a plurality of water spray holes and water mist holes are provided on the surface of the nozzle 6, and the plurality of water spray holes and water mist holes are distributed in a ring shape on the surface of the nozzle 6. The water spray holes are mainly used to spray out water flows with larger particles. These water flows with larger particles have a certain impact force, which can quickly moisten the air and dust in the mine tunnel, causing the dust particles to condense and become larger, making it easier to settle. The water mist holes can spray out fine water mist particles. These water mist particles have a high surface area and can better absorb fine dust particles in the air. Since the water mist particles are very small, they can be suspended in the air for a long time, fully contact with the dust, and improve the dust removal effect. In addition, the water mist can also reduce the temperature in the mine tunnel and improve the working environment.

[0032] The top of the connecting rod 4 is spherical, and a spherical groove corresponding to it is opened at the bottom end of the connecting block 5, and the top of the connecting rod 4 is embedded in the spherical groove. This connection method allows the connecting block 5 to rotate freely at multiple angles relative to the connecting rod 4 within a certain range. In this way, the angle of the nozzle 6 can be flexibly adjusted according to actual needs, so that it can better aim at the dust source for spraying, thereby improving the dust removal effect. In open-pit mines, the terrain may be uneven. This connection method can also enable the nozzle 6 to adapt to different terrain changes to a certain extent, maintain a good spraying angle, and ensure the stability of the dust removal work.

[0033] A groove is provided on the inner wall of the fixing ring 7, and the inner wall of the groove is arc-shaped. The ball 10 is embedded in the arc-shaped groove. There are multiple balls 10, and the ball 10 is against the outer wall of the lifting rod 3. The ball 10 rolls between the arc-shaped groove and the outer wall of the lifting rod 3, providing guidance for the up and down movement of the lifting rod 3, ensuring that the lifting rod 3 can move vertically up and down under the drive of the screw rod 11, preventing deviation or shaking, ensuring the accuracy of the height adjustment of the nozzle 6, and at the same time reducing the friction resistance between the fixing ring 7 and the lifting rod 3, making the movement of the lifting rod 3 smoother, reducing the power required to drive the screw rod 11, and reducing the wear of components, thereby extending the service life of the equipment.

[0034] The top of the fixing rod 8 is fixedly connected to the bottom of the fixing ring 7, and the bottom of the fixing rod 8 is fixedly connected to the top of the base 1. A threaded hole is provided at the bottom of the lifting rod 3, and the screw rod 11 is inserted into the threaded hole and is threadedly connected to the lifting rod 3. When the screw rod 11 rotates clockwise or counterclockwise, the lifting rod 3 will move up or down along the screw rod 11 due to the action of the thread. At the same time, when the screw rod 11 stops rotating, the lifting rod 3 will not move easily under the action of gravity or external force due to the friction and self-locking characteristics of the thread, and can maintain the adjusted height position to ensure that the spraying height of the sprinkler head 6 is stable.

[0035] Working principle:

[0036] When the height of the nozzle 6 needs to be adjusted, the staff rotates the rotating shaft 9 to drive the worm 12 to rotate. The rotation of the worm 12 drives the worm gear 13 to rotate, and then the screw rod 11 rotates. Due to the threaded connection between the screw rod 11 and the lifting rod 3, the lifting rod 3 will move up and down with the rotation of the screw rod 11, and the movement of the lifting rod 3 is transmitted to the connecting block 5 through the connecting rod 4, thereby adjusting the height of the nozzle 6. After adjusting to the appropriate height, the self-locking performance of the worm gear 13 and the worm 12 can keep the screw rod 11 stable, and the nozzle 6 can also perform spraying and dust removal at this height. At the same time, the top of the connecting rod 4 is spherical and embedded in the spherical groove at the bottom of the connecting block 5, so that the connecting block 5 can be freely rotated at multiple angles relative to the connecting rod 4 within a certain range. In this way, the angle of the nozzle 6 can be flexibly adjusted according to actual conditions, so that the dust source can be better sprayed, the dust removal effect is improved, and a good spraying angle can be maintained in uneven mine terrain to ensure the stability of the dust removal work.

[0037] When the lifting rod 3 moves up and down, the ball 10 rolls between the arc groove and the outer wall of the lifting rod 3, providing guidance for the lifting rod 3, ensuring that it can move vertically up and down under the drive of the screw rod 11, preventing deviation or shaking, and ensuring the accuracy of the height adjustment of the nozzle 6. At the same time, the rolling of the ball 10 reduces the friction resistance between the fixing ring 7 and the lifting rod 3, making the lifting rod 3 move more smoothly, reducing the power required to drive the screw rod 11, reducing component wear, and extending the service life of the equipment.

[0038] The present invention is not limited to the above-described embodiments. Any structural changes made under the guidance of the present invention should be understood by anyone. Any technical solution that is the same or similar to the present invention falls within the scope of protection of the present invention. The technology, shape, and structure not described in detail in the present invention are all known technologies.
