Description

Technical Field

[0001] This utility model relates to the field of dust suppression equipment technology, specifically to a dust suppression rocker arm nozzle for dust suppression in stockyards. Background Technology

[0002] The rocker arm sprinkler is a commonly used sprinkler system for outdoor irrigation and an important water emitter in irrigation equipment. The rocker arm sprinkler uses water flow to drive the rocker arm to swing, which in turn rotates the sprinkler head, achieving wide-area spraying. The water mist sprayed by the rocker arm sprinkler adsorbs particulate matter in the air, thus playing a role in dust suppression. Therefore, rocker arm sprinklers are also widely used in dust control fields (such as construction sites, mines, roads, etc.).

[0003] Currently, when rocker arm sprinklers are used in mines and storage yards, a limiting ring is typically used to confine the sprinkler to a fan-shaped area for spraying. Referring to the reversing rocker arm sprinkler disclosed in CN102806157A, the limiting ring currently used mainly consists of two retaining rings, each extending outwards with a baffle plate. These two baffle plates confine the sprinkler to a fan-shaped area, causing the reversing mechanism of the rocker arm sprinkler to continuously impact the limiting ring baffle plate. However, dust suppression in mines and storage yards involves fixed locations and angles with prolonged spraying; this continuous impact on the limiting ring can lead to deformation and other problems.

[0004] In addition, the elevation angle of current rocker-arm nozzles is fixed, and the range control is mainly achieved by adjusting the system pressure through booster pumps or pressure reducing valves. However, in mines and stockpiles, due to limited conditions, it is impossible to equip them with corresponding pressure regulating systems, resulting in the inability to adjust the range or the inconvenience of adjustment.

[0005] Therefore, there is a need for a rocker-arm nozzle suitable for dust suppression in places such as mines and storage yards. Summary of the Invention

[0006] To address the aforementioned issues, this utility model provides a dust suppression rocker arm nozzle for dust suppression in stockpiles. It can spray dust suppression in a fixed fan-shaped area in mines and stockpiles, and the pitch angle can be adjusted according to the actual usage scenario, thereby adjusting the spraying height and distance.

[0007] Specifically, this utility model is implemented as follows:

[0008] A dust suppression rocker arm nozzle for dust suppression in a stockpile includes: a nozzle body, a reversing device, a limiting device, and a rotating mechanism. The limiting device is a U-shaped limiting member bent from a baffle, which is detachably installed in the rotating mechanism, and the reversing arm of the reversing device is located inside the U-shaped limiting member.

[0009] Below the rotating mechanism is a pitch angle adjustment mechanism, which is used to adjust the pitch angle of the nozzle body.

[0010] Furthermore, a screw is provided on the U-shaped limiting member, and the screw and the U-shaped limiting member form a clamping structure for clamping the rotating mechanism together, and nuts for fastening are provided on both sides of the screw.

[0011] Furthermore, the pitch angle adjustment mechanism includes:

[0012] The ball joint connects to the rotating mechanism at the top and to the water pipe at the bottom;

[0013] A fixing component, located on the spherical joint and connected to the rotating mechanism, is used to fix the pitch angle of the nozzle body.

[0014] Furthermore, the water pipe is provided with a first flange at the top, and the ball joint includes:

[0015] The base is connected to the first flange via a second flange.

[0016] The ball head is located at the lower part of the rotating mechanism and is connected to the rotating mechanism. The ball head is installed inside the base.

[0017] Furthermore, the base is provided with a limiting groove in the horizontal direction, and the ball head is provided with a limiting part that matches the limiting groove. The limiting part is located in the limiting groove and is used to restrict the ball head from rotating in the horizontal direction.

[0018] Furthermore, the fixing component includes:

[0019] A fixed ring is located outside the rotating mechanism;

[0020] At least two limiting screws are provided, with the lower part of each limiting screw hinged to the first flange and the upper part connected to the fixing ring;

[0021] Two adjusting nuts are provided, which are located on the upper and lower sides of the fixing ring respectively and are connected to the limiting screw.

[0022] Furthermore, the second flange has an elliptical ring structure, and a sealing ring is provided between it and the first flange.

[0023] Furthermore, a hinge seat is provided on the first flange, and the bottom of the limiting screw is hinged to the hinge seat.

[0024] The working principle of this utility model:

[0025] A baffle plate 12 is provided above the nozzle 11 of the nozzle body 1. When the pressurized water from the nozzle 11 is sprayed out, it impacts the guide plate 13 through the baffle plate 12, causing the rocker arm 14 to generate a tangential motion force and rotate around the rotating shaft 15 at a certain angle. Then, under the action of the torsion spring, it returns and impacts the striking block 16 on the nozzle 11, causing the nozzle 11 to rotate at a certain angle. When the commutator 2 at the end of the nozzle 11 rotates with the nozzle 11, it is restricted by the U-shaped limiting member 4. When the commutator 4 rotates and impacts the baffle of the U-shaped limiting member 4, the nozzle 11 rotates, thereby realizing the reciprocating motion of the nozzle body 1 within the limiting area of ​​the U-shaped limiting member 4.

[0026] When the pitch angle needs to be adjusted, loosen the adjusting nut 582 on the limiting screw 58 to release the restriction of the limiting screw 58 on the ball joint, allowing the ball head 52 to rotate up and down within the base 51, thereby driving the nozzle body 1 to adjust the pitch angle. After adjustment, tighten the adjusting nut 582 to fix it. The larger the pitch angle of the nozzle body 1, the higher its spray height and the shorter the relatively shorter the horizontal spray distance.

[0027] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0028] (1) The dust suppression rocker arm nozzle for dust suppression in the stockyard provided by this utility model uses a detachable U-shaped limiting component to limit the spraying area of ​​the nozzle, thereby meeting the spraying requirements of a relatively fixed spraying area. At the same time, the baffle structure design of the U-shaped limiting component can effectively improve the strength of the limiting component and increase its service life.

[0029] (2) The lower part of the dust suppression rocker arm nozzle used for dust suppression in the storage yard is equipped with a pitch angle adjustment mechanism. Through this mechanism, the spraying height and spraying horizontal distance of the nozzle can be adjusted to meet the needs of different dust heights and different spraying ranges, thereby achieving effective dust suppression in the area.

Detailed Implementation

[0040] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Example

[0041] like Figure 1-4 As shown, this embodiment provides a rocker arm nozzle for dust suppression in stockpiles. The pitch angle of the rocker arm nozzle can be adjusted according to the height of the stockpile to meet the requirements for dust suppression in stockpiles. Specifically, the rocker arm nozzle includes: a nozzle body 1, a reversing device 2, a limiting device, a rotating mechanism 3, and a pitch angle adjustment mechanism 5. The nozzle body 1 includes a nozzle pipe 11, a baffle plate 12, a guide plate 13, a rocker arm 14, and a striking block 16. The nozzle is located at the front end of the nozzle pipe 11. The rocker arm 14 is mounted on the upper part of the nozzle pipe 11 via a rotating shaft 15, on which a torsion spring is installed. The baffle plate 12 and the guide plate 13 are located at the front end of the rocker arm 14. The rotating mechanism 3 is located at the end of the nozzle pipe away from the nozzle. The lower part of the rotating mechanism 3 is connected to a water pipe 6 via the pitch angle adjustment mechanism 5. The reversing device 2 is located at the end of the nozzle pipe 11 and rotates with the nozzle pipe 11. When the pressurized water from the nozzle of the spray pipe 11 is sprayed out from the rocker arm 14, it impacts the guide plate 13 through the baffle plate 12, causing the rocker arm 14 to generate tangential motion force and rotate around the rotating shaft 15 at a certain angle. Then, under the action of the torsion spring, it returns and hits the striking block 16 on the spray pipe 11, causing the spray pipe 11 to rotate at a certain angle.

[0042] A limiting device is provided below the commutator 2 to limit the rotation range of the nozzle 11. In this embodiment, the limiting device is a U-shaped limiting member 4 bent from a baffle, on which a screw 41 is provided. The screw 41 and the U-shaped limiting member 4 form a clamping cavity for the first connecting pipe 32 of the clamping rotation mechanism 3. Nuts for fastening are provided on both sides of the screw 41. The two ends of the U-shaped limiting member 4 extend beyond the screw 41 by a certain length so that the commutator arm of the commutator 2 is located within the U-shaped limiting member 4, thereby blocking the commutator arm of the commutator 2. When the commutator arm of the commutator 2 rotates and hits the baffle, the nozzle 11 rotates, realizing the reciprocating motion of the nozzle body 1 within the limiting area of ​​the U-shaped limiting member 4. In this application, a U-shaped limiting member 4 formed by bending a baffle with high strength is used to block the commutator arm, which not only meets the needs of fixed-range dust suppression spraying in places such as mines and stockpiles, but also avoids the deformation problems that occur when existing limiting rings are used for a long time.

[0043] The rotating mechanism 3 includes a rotating part 31, a first connecting pipe 32, and a second connecting pipe 33. The rotating part 31 is located at the end of the nozzle 11 and is rotatably connected to the first connecting pipe 32. The upper part of the second connecting pipe 33 is threadedly connected to the first connecting pipe 32, and the lower part is connected to the pitch angle adjustment mechanism 5. Figure 5-7 As shown, the pitch angle adjustment mechanism 5 includes a ball joint and a fixing component. The ball joint includes a base 51 and a ball head 52. The bottom of the base 51 is a second flange 56, which is connected to the first flange 55 at the top of the water pipe 6. A sealing ring 57 is provided between the two for sealing. The first flange 55 is a conventional disc flange, and the second flange 56 adopts an elliptical ring structure design so that after the two are connected, the installation position of the limiting screw 58 of the fixing component can be left in the first flange 55. The base 51 is provided with two limiting grooves 53 in the horizontal direction. The ball head 52 is provided with a limiting part 54 that matches the limiting groove 53. The limiting part 54 is located in the limiting groove 53 to restrict the horizontal rotation of the ball head 52, so that the ball head 52 can only rotate up and down. It should be noted that the ball head 52 is a hollow structure and is connected to the second connecting pipe 33 for water supply.

[0044] The fixing assembly includes a fixing ring 34, a limiting screw 58, and an adjusting nut 582. The fixing ring 34 is fixed to the second connecting pipe 33. There are two limiting screws 58. The lower part of each limiting screw 58 is hinged to the hinge seat 581 on the first flange 55, and the upper part is connected to the fixing ring 34 through two adjusting nuts 582. When it is necessary to adjust the pitch angle of the nozzle 11, the adjusting nuts 582 on the limiting screw 58 are loosened to release the limitation of the limiting screw 58 on the ball joint, so that the ball head 52 can rotate up and down in the base 51, thereby driving the nozzle body 1 to adjust the pitch angle. After the adjustment is completed, the adjusting nuts 582 are tightened to fix it. The larger the pitch angle of the nozzle body, the higher its spray height and the shorter the horizontal spray distance, which meets the dust suppression requirements of different dust heights.
