Description

Technical Field

[0001] This utility model relates to the field of dust control, specifically to an automated dust control spraying device. Background Technology

[0002] Dust suppression spraying devices are equipment used to control the spread of dust. They are widely used in construction sites, mines, storage yards and other places where dust is easily generated. They use a high-pressure water pump to deliver water to the nozzles, forming a fine water mist that adsorbs dust particles in the air and causes them to settle, thereby achieving the dust suppression effect.

[0003] Chinese patent CN219400615U discloses a wide-angle spray bar, including a connecting square tube and a spray pipe. A water inlet pipe is connected to the lower right end of the connecting square tube, and a fixing seat is installed on the left side of the connecting square tube. The spray pipe passes through the middle of the fixing seat and is connected to the fixing seat via a bearing. Multiple spray heads are arrayed on the left side of the spray pipe. A corrugated pipe is connected to the upper end of the connecting square tube, and the left end of the corrugated pipe is conductively connected to the spray pipe. A transmission box is installed on the upper right side of the connecting square tube. This wide-angle spray bar, by setting an impeller structure, uses high-pressure water flow as power and a transmission structure to drive the spray pipe to reciprocate, increasing its spray angle. It eliminates the need for a power source, saving operating costs. Compared to traditional spray pipes that add spray heads, this structure has less impact on water flow and spray pressure, and allows for adjustment of the spray range, making it more convenient to use. However, this device still has the following problems:

[0004] 1. This device can only be installed at a fixed height. Spraying at different heights is required at the construction site according to the construction situation.

[0005] 2. The deployment needs to be adjusted according to the construction site. The device is not easy to move, which is a waste of time.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0034] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0040] In this invention, after the operator moves the device to the construction site where spraying is required, the bottom housing 1 is quickly fixed using the fixing mechanism 5, and then the adjustment drive assembly 41 is activated. The adjustment drive assembly 41 drives the middle housing 2 to rise through the middle transmission assembly 42, and at the same time, the middle transmission assembly 42 drives the upper housing 3 to rise through the upper transmission assembly 43, thereby achieving a multi-fold lifting of the spray assembly 6 on the upper housing 3. After the spray assembly 6 is aligned with the construction site, spraying begins to achieve the effect of dust reduction. After the construction is completed and dust reduction is no longer required, the adjustment drive assembly 41 drives the middle housing 2 and the upper housing 3 to reset again, and at the same time, the spray assembly 6 automatically rewinds.

[0046] The fixed frame drive assembly 51 includes a sliding frame 511 and a U-shaped block 512; the sliding frame 511 is slidably connected to the outer side wall of the bottom housing 1, and a plurality of U-shaped blocks 512 are arranged in a circumferential array on the outer side of the bottom housing 1; the upper end of the U-shaped block 512 is fixedly connected to the sliding frame 511, and the U-shaped block 512 is connected to the convenient fixing assembly 52.

[0047] The convenient fixing assembly 52 includes an upper connecting rod 521 and a lower connecting rod 522; on the outer sides of the plurality of upper connecting rods 521 and lower connecting rods 522, the upper end of the upper connecting rod 521 is hinged to the U-shaped block 512; the lower end of the upper connecting rod 521 is hinged to the upper end of the lower connecting rod 522; the lower end of the lower connecting rod 522 is hinged to the lower outer wall of the bottom housing 1; the length of the upper connecting rod 521 is greater than the length of the lower connecting rod 522.

The sliding frame 511 slides downward and drives the lower connecting rod 522 to rotate around the hinge point between the lower connecting rod 522 and the bottom housing 1 through the upper connecting rod 521. After the outer side of the lower connecting rod 522 abuts against the ground, screw 531 is unscrewed to connect with the screw hole 532 on the lower side of the outer side of the bottom housing 1 to fix the position of the sliding frame 511. At this time, multiple sets of lower connecting rods 522 cooperate to fix the device, thus completing the convenient fixation of the device.

After the construction is completed and dust suppression is no longer required, the motor 411 is started again to lower the height of the middle housing 2 and the upper housing 3. At this time, the automatic hose reel assembly 63 automatically reels the water hose 62.
