Description

Technical Field

[0001] This utility model belongs to the field of dust suppression machines, specifically, it relates to a multi-directional adjustable environmentally friendly dust suppression machine for building demolition. Background Technology

[0002] During the demolition of old buildings, dust suppression devices are required. Currently, the most commonly used device is the fog cannon, which uses a water pump and a fan to generate a large amount of water mist to suppress dust in the demolition area.

[0003] Chinese patent CN220758504U discloses an environmentally friendly dust suppression device for building demolition. When the user pulls the handle outward, the limiting plate and the movable groove rod move horizontally and away from the spray nozzle. At this time, the locking block separates from the movable groove rod, and the spray nozzle can be moved out directly, which is more convenient. Similarly, when installing the spray nozzle, the user first pulls the handle outward to make the movable groove rod retract into the fixed plate, aligns the locking block of the spray nozzle with the groove of the movable groove rod, and releases the handle. Under the influence of the spring rebound force, the movable groove rod pops out and fits on the outside of the locking block to limit the spray nozzle.

[0004] However, the aforementioned environmental dust suppression device for building demolition can only adjust the height of the spray nozzle through a convenient mechanism, but cannot adjust the horizontal position of the spray nozzle. After the dust suppression device stops, it can only suppress dust in one direction, which affects the dust suppression range.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

[0028] Please see Figure 2 As shown, the water spraying mechanism 4 in this embodiment includes a U-shaped frame 401 located on the upper side of the gear 3, a spray nozzle 402 located inside the U-shaped frame 401, a water pump 403 connected to the upper side of the water storage tank 2, and a corrugated pipe 404 connected between the water pump 403 and the spray nozzle 402. The bottom end of the water pump 403 is provided with a water inlet pipe extending into the lower part of the water storage tank 2. The bottom surface of the U-shaped frame 401 is higher than the upper side of the transmission bar 10. The spray nozzle 402 is vertically rotatably fitted inside the U-shaped frame 401. A second servo motor 405 is provided on one side of the U-shaped frame 401 for driving the spray nozzle 402 to rotate vertically. This facilitates the water pump 403 to draw water out of the water storage tank 2 through the water inlet pipe and spray it out through the corrugated pipe 404 and the spray nozzle 402 to reduce dust. The second servo motor 405 is turned on to drive the spray nozzle 402 to rotate, which facilitates the adjustment of the dust reduction direction and height, and facilitates multi-directional dust reduction.

[0029] Please see Figure 2-4 As shown, the transmission disk 7 in this embodiment is provided with a T-shaped groove 11 on the upper side, the slider 8 is a T-shaped block structure, the slider 8 is slidably fitted in the T-shaped groove 11, one end of the threaded rod 9 is on the inner wall of the T-shaped groove 11, and one end of the threaded rod 9 is provided with a handwheel 12, which facilitates guiding the slider 8 to slide through the T-shaped groove 11 and improves the stability of the slider 8 sliding.

[0030] Please see Figure 2-3 As shown, the upper side of the slider 8 in this embodiment is provided with a first rotating shaft 13, and a first bearing is fixedly sleeved on the first rotating shaft 13. The first end of the transmission bar 10 is fixedly sleeved on the first bearing, so as to improve the stability of the transmission bar 10 rotating on the slider 8 through the first rotating shaft 13 and the first bearing.

[0032] Please see Figure 2-4 As shown, the water storage tank 2 in this embodiment is provided with a T-shaped guide strip 15 on the upper side, and the rack 5 is provided with a T-shaped opening groove 16 on the bottom surface. The rack 5 slides on the T-shaped guide strip 15 through the T-shaped opening groove 16, which facilitates the rack 5 to slide on the T-shaped guide strip 15 through the T-shaped opening groove 16 and improves the stability of the rack 5 sliding.

[0033] Working principle: The first servo motor 6 drives the transmission disk 7 to rotate. The slider 8 on the transmission disk 7 drives the rack 5 to slide back and forth via the transmission bar 10, which in turn drives the gear 3 and the water spray mechanism 4 to rotate horizontally back and forth. The handwheel 12 drives the threaded rod 9 to rotate, causing the slider 8 to slide within the T-shaped groove 11 on the transmission disk 7. This facilitates adjusting the distance between the axis of the first rotating shaft 13 and the axis of the transmission disk 7, adjusting the length of the rack 5's reciprocating slide, and adjusting the angle of the gear 3 and the water spray mechanism 4's reciprocating horizontal rotation. The system is then pushed by the flatbed cart 1.
