Description

Technical Field

[0001] The utility model belongs to the technical field of dust suppression devices, in particular to a dust suppression device for a construction site. Background Art

[0002] Dust suppression devices are often used at construction sites. There are many types of dust suppression devices, one of which is the fog cannon. The fog cannon uses a high-pressure water pump to atomize water into fine particles, and then uses a fan to spray the water mist out. The fog cannon can effectively reduce dust and particulate matter in the air by spraying water mist, which plays an important role in improving the environment and air quality. In hot weather, the water mist sprayed by the fog cannon can also quickly lower the temperature and play a role in cooling down the heat.

[0003] The structure of dust suppression devices such as fog cannons usually takes up a large space and is inconvenient to carry and store. Utility Model Content

[0004] The purpose of the utility model is to provide a dust reduction device for a construction site, which can be stored after the dust reduction is completed, and is convenient for transportation and storage.

[0005] The construction site dust suppression device includes a first connecting seat with a groove structure communicating left and right, a guide cylinder with an opening facing right being transversely arranged in the first connecting seat, and connecting columns being connected to the front and rear sides of the guide cylinder, the two connecting columns being symmetrical front and back and arranged longitudinally, the front end of the connecting column located on the front side of the guide cylinder being rotatably connected to the front side groove wall of the first connecting seat, and the rear end of the connecting column located on the rear side of the guide cylinder being rotatably connected to the rear side groove wall of the first connecting seat;

[0006] The bottom of the guide cylinder on the left side of the connecting column is detachably connected to a hydraulic rod that can be extended and retracted up and down. The upper end of the hydraulic rod is the telescopic end and is hinged to the guide cylinder, and the lower end is hinged in the first connecting seat;

[0007] When the hydraulic rod is shortened downward, the left end of the guide cylinder swings downward and the right end swings upward;

[0008] After the telescopic end of the hydraulic rod is disconnected from the guide cylinder, the right end of the guide cylinder swings downward;

[0009] The bottom of the first connecting seat is connected to a base that is rotated left and right.

[0010] After the guide cylinder finishes spraying, the connection between the telescopic end of the hydraulic rod and the guide cylinder is released, and the right end of the guide cylinder swings downward with the connecting column as the axis for vertical storage, which is convenient for transportation and storage; when the hydraulic rod is shortened downward, the left end of the guide cylinder swings downward and the right end swings upward, which is convenient for adjusting the spray height of the guide cylinder. The bottom of the first connecting seat is connected to a base that can be rotated left and right, which is convenient for adjusting the spray angle of the guide cylinder by rotating the first connecting seat left and right; the hydraulic rod is hinged in the first connecting seat, and when the right end of the guide cylinder swings downward, the upper end of the hydraulic rod swings to facilitate cooperation with the guide cylinder for storage together.

[0011] Furthermore, transverse waist-shaped holes are provided on the front and rear groove walls of the first connecting seat corresponding to the connecting columns, and the connecting columns are independently installed in the waist-shaped holes.

[0012] The front end of the connecting column located at the front end of the guide cylinder is connected to the waist-shaped hole on the front side groove wall of the first connecting seat in a rotational fit, and the rear end of the connecting column located at the rear end of the guide cylinder is connected to the waist-shaped hole on the rear side groove wall of the first connecting seat in a rotational fit. This not only facilitates the rotation of the connecting column in the waist-shaped hole to adjust the spray height of the guide cylinder, but also allows the connecting column to move left and right along the waist-shaped hole to adjust the downward swing position of the right end of the guide cylinder after the guide cylinder is disconnected from the hydraulic rod.

[0013] Furthermore, a lifting lug is fixed to the bottom of the guide cylinder, and the upper end of the hydraulic rod is hinged to the lifting lug through an eccentric cam clamping rod.

[0014] Specifically, two lifting ears are fixed at a front-to-back interval at the bottom of the guide cylinder, and then the upper end of the hydraulic rod is installed between the front and rear lifting ears through the eccentric cam clamping rod to achieve hinge connection, so that when the hydraulic rod is extended or retracted, it drives the guide cylinder to swing up and down to adjust the spray height.

[0015] Furthermore, a second connecting seat is fixed to the inner bottom of the first connecting seat, and the lower end of the hydraulic rod is hinged to the second connecting seat.

[0016] The second connecting seat is conveniently hinged to the bottom of the hydraulic rod through a pivot after a hole is punched thereon, so that the hydraulic rod can be easily swung left and right.

[0017] Furthermore, a first groove for accommodating the guide tube is formed at the right end of the first connecting seat.

[0018] The first groove facilitates the right end of the guide cylinder to be vertically received into the first connecting seat together with the connecting column and the waist-shaped hole after the right end of the guide cylinder swings downward.

[0019] Furthermore, a second groove for accommodating the guide cylinder is provided at the right end of the base.

[0020] The second groove located below the first groove facilitates the vertical storage of guide cylinders of different lengths.

[0021] Furthermore, a rotating base is fixed to the bottom of the first connecting seat, the upper end of the rotating base is fixed to the first connecting seat, and the lower end is connected to the base in a left-right rotating manner.

[0022] The installation method between the rotating base and the base can be to fix a bearing on the base, and the lower end of the rotating base is connected to the bearing to realize the left and right rotation of the rotating base relative to the base, or other rotating connection methods in the prior art.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] After the guide cylinder finishes spraying, the connection between the telescopic end of the hydraulic rod and the guide cylinder is released, and the right end of the guide cylinder swings downward with the connecting column as the axis for vertical storage, which is convenient for transportation and storage; when the hydraulic rod is shortened downward, the left end of the guide cylinder swings downward and the right end swings upward, which is convenient for adjusting the spray height of the guide cylinder. The bottom of the first connecting seat is connected to a base that can be rotated left and right, which is convenient for adjusting the spray angle of the guide cylinder by rotating the first connecting seat left and right; the hydraulic rod is hinged in the first connecting seat, and when the right end of the guide cylinder swings downward, the upper end of the hydraulic rod swings to facilitate cooperation with the guide cylinder for storage together.
