[0068] See also Figure 1-Figure 12 The present invention provides an embodiment: a spray dust reduction device for a highway construction mixing site, comprising: a slide rail 100, the slide rail 100 is fixedly installed on the side of the mixing station, a moving seat 200 for driving the spray dust reduction device to move is movably installed on the slide rail 100, a first cylinder 300 for adjusting the height of the spray dust reduction device is fixedly installed on the moving seat 200, a support plate 400 is fixedly installed on the output end of the first cylinder 300, a moving frame 500 is movably installed on the support plate 400, a mounting plate 600 is movably installed on the side of the moving frame 500, a spray pipe 700 for dust reduction when the mixing station is loaded is installed at the bottom of the mounting plate 600, the mounting plate 600 includes a bending structure for bending the spray pipe 700, and the moving frame 500 includes a driving component for the movement of the spray pipe 700, and a conversion component for exchanging the function of the driving component;

[0069] It should be understood that the mixing station will be loaded with sand and gravel during operation, and a large amount of dust will be generated during the loading process. At this time, the movable seat 200 can move on the slide rail 100 through the operation of the commonly used driving components on the market. When the movable seat 200 moves, it can drive the spraying pipe 700 to move to the position where the sand and gravel are loaded for dust reduction. At the same time, the first cylinder 300 can adjust the height of the spraying pipe 700 according to the height of the sand and gravel. The movable frame 500 can adjust the spraying position, spraying angle and spraying range of the mounting plate 600 and the spraying pipe 700 through the cooperation of the driving component and the conversion component.

[0070] like Figure 1-Figure 11 As shown, the driving assembly includes a motor 530 and a rotating shaft 540 for the movement of the spray pipe 700, and a second cylinder 510 and a push plate 520 for the movement and installation of the motor 530;

[0071] A second cylinder 510 is fixedly mounted on the top of the moving frame 500, an upper portion of a push plate 520 is fixedly mounted on the output end of the second cylinder 510, a motor 530 is fixedly mounted on the middle portion of the push plate 520, the motor 530 is located in the middle portion of the moving frame 500, and a rotating shaft 540 is fixedly mounted on the output end of the motor 530;

[0072] It can be imagined that when the second cylinder 510 is working, it can drive the push plate 520 to move, and when the push plate 520 moves, it can drive the motor 530 and the rotating shaft 540 to move, and when the rotating shaft 540 moves, it can dock with the conversion component. When the rotating shaft 540 moves to the specified position, the motor 530 can drive the rotating shaft 540 to rotate when working, and when the rotating shaft 540 rotates, it can drive the corresponding parts to work through the conversion component.

[0073] like Figure 1-Figure 10 and Fig.12As shown, the conversion assembly includes an outer sleeve 550, a middle sleeve 560, an inner sleeve 570 and a push groove 580 for docking with the rotating shaft 540;

[0074] An outer sleeve 550 is rotatably mounted on the surface of the moving frame 500 through an assembly hole, a middle sleeve 560 is rotatably mounted in the inner cavity of the outer sleeve 550, and an inner sleeve 570 is rotatably mounted in the inner cavity of the middle sleeve 560. Push grooves 580 are symmetrically provided on the inner walls of the axial centers of the outer sleeve 550, the middle sleeve 560 and the inner sleeve 570.

[0075] The left ends of the outer sleeve 550, the middle sleeve 560 and the inner sleeve 570 are arranged in a stepped shape.

[0076] It can be understood that the rotation of the outer sleeve 550 can drive the movable frame 500, the mounting plate 600 and the spray pipe 700 to move along the support plate 400 through the sliding structure, and the rotation of the middle sleeve 560 can drive the mounting plate 600 to rotate through the rotating structure. When the mounting plate 600 rotates, it can drive the spray pipe 700 to rotate. When the spray pipe 700 rotates, the spraying angle can be adjusted. When the inner sleeve 570 rotates, it can drive the bending structure to work through the gear set, and the bending structure can bend the spray pipe 700.

[0077] like Figure 5 , Figure 6 , Fig. 9 and Fig.10 As shown, the rotating shaft 540 also includes a docking structure for connecting the conversion assembly, and the docking structure includes a clamping block 543 for docking with the pushing groove 580, and a reset spring 542 and a first extrusion groove 541 for resetting the clamping block 543;

[0078] A first extrusion groove 541 is symmetrically provided on the outer surface of the axial center of the rotating shaft 540 near the end, and the end of a return spring 542 is fixedly installed inside the first extrusion groove 541. A block 543 cooperating with the push groove 580 is fixedly installed on the other end of the return spring 542. Inclined surfaces are symmetrically provided on both sides of the end of the block 543 near the push groove 580.

[0079] It should be noted that when the second cylinder 510 is working, it pushes the end of the rotating shaft 540 to move first into the cavity at the left end of the outer sleeve 550. When the rotating shaft 540 moves, it can drive the inclined surface of the clamping block 543 to squeeze the end of the outer sleeve 550. When the clamping block 543 is squeezed, it can slide inside the first squeezing groove 541. When the clamping block 543 slides, it can compress the reset spring 542. When the clamping block 543 is squeezed to the specified position, it will move to the inner cavity of the outer sleeve 550 through the rotating shaft 540. When the clamping block 543 moves to the same vertical plane as the pushing groove 580, the motor The operation of 530 can drive the rotating shaft 540 and the block 543 to rotate. When the block 543 rotates to the position of the pushing groove 580, the block 543 can be reset and inserted into the inside of the pushing groove 580 through the elastic force of the reset spring 542. At this time, the rotating shaft 540 will continue to drive the block 543 to rotate. When the block 543 rotates, it can drive the outer sleeve 550 to rotate through the pushing groove 580. The rotating shaft 540 and the block 543 can be connected and rotated in the same way as the middle sleeve 560 and the inner sleeve 570 through the cooperation of the second cylinder 510 and the motor 530.

[0082] When the outer sleeve 550 rotates, it can rotate through the movable frame 500. When the outer sleeve 550 rotates, it can drive the surface gear 551 to rotate. When the gear 551 rotates, it can mesh and rotate through the rack 552. When the gear 551 meshes and rotates, the movable frame 500 is driven to move on the support plate 400 through the outer sleeve 550. When the movable frame 500 moves, it can drive the mounting plate 600 and the spray pipe 700 to move.

The moving frame 500 is provided with a first rotating groove 566 that matches the first rotating ring 562.

[0085] When the middle sleeve 560 rotates, it can drive the end rotating plate 561 to rotate. When the rotating plate 561 rotates, it can drive the first rotating ring 562 to rotate. When the first rotating ring 562 rotates, it can rotate inside the first rotating groove 566.

[0088] When the first rotating ring 562 rotates, it can drive the steel ball 565 to squeeze the arc-shaped inner wall of the slot 567. When the steel ball 565 is squeezed, it can slide through the second squeezing slot 563. When the steel ball 565 slides, it can squeeze the end of the clamping spring 564. When the steel ball 565 is completely squeezed into the second squeezing slot 563, the first rotating ring 562 will continue to rotate inside the first rotating slot 566. When the steel ball 565 rotates to the position of another slot 567, the steel ball 565 can be engaged and connected with the other slot 567 through the elastic force of the clamping spring 564. When the rotating shaft 540 is disengaged from the end of the middle sleeve 560, the middle sleeve 560 can avoid self-rotation through the cooperation between the steel ball 565 and the slot 567.
