For example, the object "provided with" may be a part of the body, or may be arranged separately from the body and connected to the body, and the connection may be a detachable connection or an inseparable connection. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0026] The present invention is further described in detail below in conjunction with the embodiments.
[0027] Specific embodiments of the dust suppression device for highway construction provided by the utility model:
[0028] See also Figure 1-5 The dust suppression device for highway construction includes a base 14, which can be installed on a cart or a motor vehicle; a horizontally rotating turntable 1 is rotatably installed on the upper side of the base 14, and a rotating support for supporting the rotation of the turntable 1 is provided between the turntable 1 and the base 14.
[0029] The spray gun 2 is installed on the turntable 1. Specifically, a bracket 9 is provided on the upper side of the turntable 1. The bracket 9 is U-shaped. The spray gun 2 is rotatably installed on the upper end of the bracket 9. The upper end of the bracket 9 is provided with a bearing for supporting the rotation of the spray gun 2. The rotation of the spray gun 2 can realize the pitch angle adjustment.
[0030] The spray cannon 2 is a prior art. The spray cannon 2 includes a cylinder. A fan is provided at the rear end of the cylinder. The fan introduces outside air into the cylinder. A grid is provided at the entrance to prevent outside debris from being introduced into the fan. A plurality of annularly distributed spray heads are provided at the front end of the cylinder. The spray heads can be connected to the liquid supply device through a hose. The airflow generated by the fan transports the spray under the restriction of the cylinder, and brings the mist droplets to the dust-raising area.
[0031] In order to position the pitch angle of the spray cannon 2, a telescopic rod is hinged between the spray cannon 2 and the upper side of the turntable 1. In this embodiment, the telescopic rod is a turnbuckle bolt 10, and the pitch angle of the spray cannon 2 can be adjusted by adjusting the length of the turnbuckle bolt 10.
[0032] The turntable 1 is in the shape of a disk, and a gear ring 3 is provided on the outer edge of the turntable 1, and a rack 4 that moves back and forth in a straight line is meshed through the gear ring 3. A guide rod 11 is fixedly provided on the upper side of the base 14, and the cross-section of the guide rod 11 is in the shape of a square. The guide rod 11 passes through the rack 4; the rack 4 slides linearly along the guide rod 11. The square cross-section guide rod 11 can prevent the rack 4 that moves linearly from rotating, and ensure that the rack 4 moves linearly and reciprocates along the guide rod 11.
[0033] A rectangular frame 5 is connected to the lower side of the rack 4. In this embodiment, the length direction of the rectangular frame 5 is perpendicular to the extension direction of the rack 4. A driving turntable 6 and a reduction motor 12 for driving the driving turntable 6 to rotate are arranged on the base 14.
[0034] The diameter of the active turntable 6 is the same as the length of the rectangular frame 5 and the positions are corresponding. A driving column 8 is installed on the upper side of the active turntable 6, and the upper part of the driving column 8 extends into the rectangular frame 5. The active turntable 6 is provided with a plurality of mounting holes 7 evenly distributed in the radial direction for mounting the driving column 8. In this embodiment, the mounting holes 7 are arranged in a plurality of groups, each group is distributed radially, and each group is evenly distributed around the circumference.
[0035] In this embodiment, the mounting holes 7 are all internal threaded holes, and one end of the driving column 8 is provided with a threaded section 81 threadedly connected to the mounting hole 7; the other end of the driving column 8 is provided with a hexagonal section 82. When installing the driving column 8, the threaded section 81 is aligned with the mounting hole 7 to be fixed, and the hexagonal section 82 is rotated with a wrench to screw the threaded section 81 into the mounting hole 7 and tighten it.
[0036] A rotatable sleeve 13 is sleeved on the outside of the driving column 8. The outside of the driving column 8 has an annular groove for the sleeve 13 to rotate. The outer diameter of the sleeve 13 is slightly smaller than the inner width of the rectangular frame 5. When the driving column 8 drives the rectangular frame 5 to move, the sleeve 13 can reduce friction and wear.
[0037] The reduction motor 12 drives the active turntable 6 to rotate, so that the driving column 8 rotates, and the driving column 8 makes the rectangular frame 5 and the rack 4 move back and forth, and the rack 4 drives the turntable 1 and the spray gun 2 to swing back and forth within a certain angle to achieve spray dust reduction. When it is necessary to adjust the swing range of the spray gun 2, the position of the driving column 8 is changed, that is, the driving column 8 is connected to the mounting holes 7 with different rotation radii, and the rotation radius of the driving column 8 is changed, so that the reciprocating stroke of the rectangular frame 5 and the rack 4 is changed, thereby changing the swing angle range of the turntable 1 and the spray gun 2.
[0038] Finally, it should be noted that the above is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments without creative work, or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
