Description

Technical Field

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

[0002] There are various types of construction at the construction site, and many of them will generate dust. Among them, for the transportation of construction waste, a bulldozer is needed to shovel up the construction waste, then lift it high, and finally dump it into the bucket of a dump truck. During the dumping process, a large amount of dust will be generated. Dust reduction fog cannons are currently used on construction sites. When the dust reduction fog cannon is in use, the water mist sprayed out is roughly in a frustum-shaped structure, and the water mist generated has a large area. Although it has a good dust reduction effect, the water mist area of ​​the dust reduction fog cannon is too large for the dust generated in the bucket of the dump truck. The bulldozer is very close to the dump truck when dumping construction waste, which will cause a large area of ​​water mist to be sprayed onto the rear of the bulldozer's bulldozer, which can easily cause the bulldozer body to become wet and contaminated with dust. In severe cases, it will also affect the clarity of the field of vision in the cab of the bulldozer, directly affecting the safety of the use of the bulldozer. Utility Model Content

[0003] The utility model aims to solve the defect in the prior art that the use safety of the bulldozer will be reduced when the dust suppression fog cannon is used, and proposes a dust suppression device for construction site construction.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Example 1

[0020] Reference Figure 1-4 A dust suppression device for construction site, comprising an electric telescopic rod 2, a mobile cart 1 and a fixed plate 3 are fixed on the electric telescopic rod 2, a rotating mechanism is fixed on the fixed plate 3, a cylinder 7 is fixed on the rotating mechanism, a shunt pipe 5 is inserted and fixed on the cylinder 7, a plurality of nozzles 6 are equidistantly fixed on the shunt pipe 5 at one end of the cylinder 7, a water supply mechanism is fixed on the shunt pipe 5 at the other end, the plurality of nozzles 6 are arranged in a straight line on the shunt pipe 5, the rotating mechanism can adjust the directions of the plurality of nozzles 6 on the shunt pipe 5, so that the spraying range of the plurality of nozzles 6 is wider, and the spraying directions of the plurality of nozzles 6 can be accurately controlled.

[0021] The rotating mechanism includes a gear ring 10, which is fixed on the cylinder 7. A gear 11 is meshed on the gear ring 10, and a motor 12 is fixed on the gear 11. The motor 12 is fixed on the fixed plate 3. The motor 12 drives the gear ring 10 to rotate through the gear 11, so that the gear ring 10 drives the cylinder 7 to rotate. Two limit assemblies are symmetrically fixed on the cylinder 7 and the fixed plate 3. The limit assemblies include a bearing 8, which is fixed on the cylinder 7, and the outer circumferential side wall of the bearing 8 is fixed on the fixed plate 3. The bearing 8 not only fixes the distance between the cylinder 7 and the fixed plate 3, but also does not affect the rotation of the cylinder 7.

[0022] When in use, the mobile cart 1 is used to push the dust suppression device for construction site to one side of the muck truck, and the bulldozer is respectively on both sides of the muck truck, and the electric telescopic rod 2 is used to adjust the height of the shunt pipe 5 to one side above the bucket of the muck truck, and then the motor 12 is started, and the motor 12 drives the gear ring 10 to rotate through the gear 11, and the gear ring 10 drives the cylinder 7 to rotate, and the cylinder 7 adjusts the spraying direction of the multiple nozzles 6 through the shunt pipe 5, so that the water mist sprayed by the multiple nozzles 6 arranged in a straight row is sprayed obliquely downward into the bucket of the muck truck, and as the construction waste in the bucket of the muck truck increases, the electric The telescopic rod 2 gradually raises the height of the diversion pipe 5, so that the multiple nozzles 6 are always at the optimal distance from the construction waste in the bucket of the dump truck, and the sprayed water mist falls on the construction waste dumped by the bulldozer of the bulldozer, thereby achieving the purpose of dust reduction. In addition, the multiple nozzles 6 are distributed in a straight line on the diversion pipe 5, which reduces the area of ​​the water mist sprayed by the multiple nozzles 6, and can accurately fall on the construction waste dropped on the bucket of the dump truck. The body of the bulldozer is on one side of the bucket of the dump truck, which will not make the body of the bulldozer wet, and will not affect the field of view of the bulldozer cab, making the bulldozer safer when in use.

[0023] Example 2

[0024] Based on Example 1, Figure 1 , 3 and 4, as another preferred embodiment of the utility model, which is different from embodiment 1 in that the water supply mechanism includes a hose 9, one end of the hose 9 is fixed on the diversion pipe 5, and the other end is fixed with a water pipe 15. The arrangement of the hose 9 will not only not affect the adjustment of the height of the diversion pipe 5, but also ensure that the hose 9 will not affect the rotation of the diversion pipe 5. A water storage component is fixed on the water pipe 15, and the water storage component includes a water tank 13. The water tank 13 is fixed on the mobile cart 1, and a water pump 14 is fixed in the water tank 13. The water pipe 15 passes through the top wall of the water tank 13 and is fixed on the water pump 14. The water pump 14 discharges the water in the water tank 13 to multiple nozzles 6 through the water pipe 15, the hose 9 and the diversion pipe 5.

[0025] When it is not needed, that is, when the electric telescopic rod 2 is retracted, the hose 9 will be piled up in a mess on the water tank 13 due to its long length. As the mobile cart 1 moves and bumps, the hose 9 may even fall off, which is not conducive to the safety of the hose 9 and the smooth movement of the mobile cart 1. A storage assembly is fixed on the water tank 13, and the storage assembly includes a linear motor 16. The linear motor 16 is fixed on the outer top wall of the water tank 13, and a fixing frame 4 is fixed on the slider of the linear motor 16. Before the electric telescopic rod 2 is extended, the linear motor 16 is started to drive the fixing frame 4 to move to the side closest to the electric telescopic rod 2. At this time, the fixing frame 4 will not affect the use of the hose 9 when the electric telescopic rod 2 is subsequently extended. When the electric telescopic rod 2 is retracted, the hose 9 is hung on the fixing frame 4, and then the fixing frame 4 is moved to the side away from the electric telescopic rod 2 by the linear motor 16 until the hose 9 is slightly stretched. Under the premise of ensuring the safety of the hose 9, the hose 9 can also be neatly stored.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
