Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, and more specifically, to a dust reduction device at a construction site. Background Art

[0002] At the construction site, the dust raised by cement fills the site and keeps swirling. In addition, the coming and going of transport vehicles will also cause the dust to spread. These floating dusts will not only cause environmental pollution, but also cause certain damage to the health of the people at the construction site. At the construction site, we will see dust reduction devices to remove dust from the construction site. The current dust reduction measure adopted at the construction site is to reduce dust through water mist sprayed from fog cannons.

[0003] The existing dust reduction device at the construction site can adjust the height of the fog cannon barrel, but the spray direction of the existing fog cannon barrel is fixed. It is not convenient to make the fog cannon barrel shake and rotate within a certain range during the spraying process, resulting in a small spray range. In addition, the existing fog cannon barrel is installed on a bracket, and the bracket is a fixed bracket whose height cannot be adjusted. It is not convenient to adjust the height of the fog cannon barrel. When dust is generated during construction at a higher position, although the height of the fog cannon barrel spray can be adjusted by adjusting the angle of the fog cannon barrel, sometimes adjusting the fog cannon barrel to a higher angle still cannot reach the corresponding height. Therefore, the height of the fog cannon barrel needs to be adjusted. Since the height of the existing fog cannon barrel is not easy to adjust, it does not meet the requirements for dust reduction at a higher position. In addition, when the existing dust reduction device at the construction site needs to adjust the horizontal direction of the fog cannon barrel, the entire dust reduction device needs to be adjusted, and it is difficult to adjust the direction of the fog cannon barrel, and its practicality is poor.

The fog cannon barrel 2 is driven to rotate by the electric cylinder 23, so that the up and down angles of the fog cannon barrel 2 can be adjusted.

[0035] In summary, when the overall equipment is in use:

[0036] First, the dust suppression device for the construction site is moved to the corresponding position, and then the locking structure on the roller on the cart 1 is used to lock the roller. In order to ensure stability, objects that hinder the rotation of the roller can be blocked on both sides of the roller. Then, the threaded column 27 is rotated counterclockwise, and the threaded column 27 rotates counterclockwise and moves upward relative to the fixed block 26, so that the threaded column 27 is separated from the cart 1. Then, the third motor 19 drives the swivel seat 21 to rotate, and the swivel seat 21 drives the connection fixed box 3, the round seat 10 and the fog cannon barrel 2 to rotate, and thereby facilitates the spray end of the fog cannon barrel 2 to be directed toward the direction where dust is generated at the construction site. The fog cannon barrel 2 is driven to rotate by the electric cylinder 23, and the upper and lower angles of the fog cannon barrel 2 are adjusted to the appropriate angle. Then, the water inlet pipe on the fog cannon barrel 2 is connected to the external water supply equipment, and water is transported to the inside of the fog cannon barrel 2 through the external water supply equipment. The water is sprayed from the fog cannon barrel 2 in the form of mist to the dusty place at the construction site, and dust reduction treatment is performed by water mist;

[0037] When it is necessary to swing the fog cannon barrel 2 to spray and increase the range of dust reduction, the second motor 11 is started, and the circular plate 12 is driven to rotate by the second motor 11, and the circular plate 12 drives the fixed column 13 to rotate. Since the fixed column 13 is located on the top side of the circular plate 12, the fixed column 13 slides in the strip groove 17 during the rotation of the circular plate 12, and the fixed column 13 drives the cross plate 16 and the convex plate 15 to move, so that the convex plate 15 slides back and forth in the convex groove 14, and drives the swing column 18 to move during the back and forth sliding of the cross plate 16. At the same time, the swing column 18 slides in the strip groove 17, and the swing column 18 drives the round seat 10 to rotate during the sliding of the strip groove 17, and the round seat 10 drives the fog cannon barrel 2 to rotate, so that the fog cannon barrel 2 swings back and forth, and the sprayed water mist is sprayed within a certain range during the swinging of the fog cannon barrel 2, thereby performing dust reduction treatment within a certain range.

[0038] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one.
