Description

Technical Field

[0001] This utility model relates to the field of water spraying and dust suppression technology, specifically, to an atomized spray dust removal device for earthwork excavation equipment. Background Technology

[0002] Currently, earthwork operations, especially in dry weather, easily generate large amounts of dust, causing significant environmental pollution and negatively impacting urban green spaces. This also poses a risk of injury to workers. Atomizing spray dust suppression devices are specialized water spraying systems used to assist in dust control for earthwork excavation equipment. Currently, mobile mist cannons are commonly used in earthwork projects to suppress dust, covering the raised dust with the water mist sprayed by the cannons and preventing pollution of the urban environment.

[0003] Because atomizing nozzles can only be used within a single range, their spraying area is relatively limited, resulting in an insignificant dust removal effect.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes an atomizing spray dust removal device for earthwork excavation equipment to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A dust suppression device for a soil excavation machine includes a connecting seat installed on the boom of the soil excavation machine. A cover is provided on the front side of the connecting seat. A connecting pipe is provided on the outer surface of the cover. An atomizing nozzle is provided at one end of the connecting pipe. The connecting pipe is connected to the cover through a movable part. An adjustment mechanism for adjusting the angle of the atomizing nozzle is provided at the top of the connecting pipe.

[0008] Preferably, the adjusting mechanism includes a U-shaped block located at the top of the connecting pipe, a threaded sleeve inside the U-shaped block, the threaded sleeve being connected to the U-shaped block via a movable shaft, and a matching lead screw passing through the threaded sleeve.

[0009] Preferably, one end of the lead screw extends into the housing and is connected to the output end of the servo motor. The servo motor is connected to the housing via a pin. A through hole is provided on the front side of the housing for the lead screw to move.

[0010] Preferably, the connecting seat is provided with a turntable connected to the cover, and the turntable is connected to the connecting seat via a rotating shaft.

[0011] Preferably, a worm gear is fitted onto the rotating shaft, and a worm is provided on one side of the worm gear to mesh with it, with one end of the worm connected to a motor.

[0012] Preferably, the connecting pipe is provided with a connecting hose, one end of which is connected to the water tank on the earthwork excavation equipment.

[0013] Preferably, the connecting seat is connected to the arm of the earthmoving excavation equipment by bolts.

[0014] The beneficial effects of this utility model are as follows: Through the coordinated design of the adjustment mechanism, the connecting pipe, and the atomizing nozzle, the threaded sleeve moves left and right with the forward and reverse rotation of the screw, causing the connecting pipe to rotate around the movable part as the axis during the movement of the threaded sleeve, thereby adjusting the angle of the atomizing nozzle. The rotation of the shaft can drive the components on the cover to rotate synchronously, thereby further adjusting the angle of the atomizing nozzle. This allows the operator to adjust the spray angle of the atomizing nozzle at any time in the cab of the earthmoving excavation equipment, enabling it to perform spraying and dust removal work in different directions for different excavation methods.

[0026] like Figure 1-3 As shown, the adjustment mechanism includes a U-shaped block 6 located at the top of the connecting pipe 3. A threaded sleeve 7 is provided inside the U-shaped block 6. The threaded sleeve 7 is connected to the U-shaped block 6 through a movable shaft 18. A matching lead screw 8 is provided through the threaded sleeve 7. One end of the lead screw 8 extends into the cover 2 and is connected to the output end of the servo motor 9. The servo motor 9 is connected to the cover 2 through a pin 10. A through hole 11 is provided on the front side of the cover 2 for the lead screw 8 to move.

[0027] Example 3;

[0028] like Figure 1-3 As shown, the connecting seat 1 is provided with a turntable 12 connected to the cover 2. The turntable 12 is connected to the connecting seat 1 via a rotating shaft 13.

[0029] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0030] In practical applications, operators in the cab of the earthmoving excavation equipment can adjust the spray angle of the atomizing nozzle at any time by controlling the operation of servo motors 9 and 16. Servo motor 9 drives lead screw 8 to rotate, and threaded sleeve 7 moves with the rotation of lead screw 8. By controlling the forward and reverse rotation of lead screw 8, the left and right movement of threaded sleeve 7 is adjusted. During the movement, threaded sleeve 7 drives connecting pipe 3 to rotate around movable part 5 as the axis through U-shaped block 6, thereby adjusting the tilt angle of atomizing nozzle 4. When it is necessary to adjust the circumferential angle of atomizing nozzle 4, motor 16 can be started to drive worm gear 15 to rotate. Worm gear 15 meshes with worm wheel 14 to drive rotating shaft 13 to rotate. Rotating shaft 13 can drive cover 2 and its components to rotate synchronously, thereby further adjusting the angle of atomizing nozzle 4.

[0031] In summary, by means of the above-mentioned technical solution of this utility model, through the cooperative design of the adjusting mechanism with the connecting pipe 3 and the atomizing nozzle 4, the threaded sleeve 7 moves left and right with the forward and reverse rotation of the screw 8, so that the threaded sleeve 7 drives the connecting pipe 3 to rotate around the movable part 5 as the axis during the movement, thereby adjusting the angle of the atomizing nozzle 4. The rotation of the rotating shaft 13 can drive the components on the cover 2 to rotate synchronously, thereby further adjusting the angle of the atomizing nozzle 4. This allows the operator to adjust the spraying angle of the atomizing nozzle at any time in the cab of the earthmoving excavation equipment, so that it can carry out spraying and dust removal work in different directions for different excavation methods.
