Description

Technical Field

[0001] This patent relates to the technical field of dust suppression devices, specifically a portable construction dust suppression device. Background Art

[0002] At present, in order to increase the portability of dust suppression devices on construction sites, water tanks and spray mechanisms are installed on trolleys for easy walking and movement. In order to facilitate the adjustment of the spray height, the existing dust suppression mechanism drives the nozzle to move up and down through a lead screw to adjust the spray height. However, the threaded seat is mostly limited by an external slider on the slide rail in the slide groove. The design of the slide rail not only takes up space on the trolley, but also has large sliding limit friction between the slider and the slide rail, and has a low service life. For this reason, we propose a construction dust suppression device that is easy to carry. Utility Model Content

[0019] The threaded seat 9 includes an outer ring 11, a vertical pipe 13 and an internal threaded ring 16. The height of the vertical pipe 13 matches the height of the screw 8. The bottom end of the vertical pipe 13 is fixedly mounted on the top of the housing of the screw motor 7. Wheel grooves 14 are provided at both the front and rear ends of the outer wall of the vertical pipe 13. Limit wheels 12 are installed at both the front and rear ends of the inner wall of the outer ring 11. The limit wheels 12 are rollingly installed in the wheel grooves 14. Strip holes 15 are provided at both the left and right ends of the side wall of the vertical pipe 13. The inner wall of the internal threaded ring 16 is screwed onto the screw 8. Connecting rods 17 are fixedly mounted on the left and right ends of the outer wall of the internal threaded ring 16. The ends of the connecting rods 17 pass through the strip holes 15 and are fixedly mounted on the inner wall of the outer ring 11.

[0020] like Figure 3 As shown, the standpipe 13 is arranged concentrically with the screw rod 8 .

[0021] The height of the strip hole 15 matches the up and down moving height range of the threaded seat 9 .

[0022] Specifically, the outer side wall of the internal thread ring 16 does not contact the inner side wall of the stand pipe 13 .

[0023] Specifically, an electric push rod 18 is hinged on the lower right side of the outer wall of the outer ring 11 through a hinge seat, and the piston rod end of the electric push rod 18 is hinged to the bottom right side of the connecting plate 10 through a hinge seat, and the left end bottom of the connecting plate 10 is hinged to the top right end of the outer ring 11.

[0024] By providing the electric push rod 18 , it is convenient to adjust the pitch spray angle of the nozzle 6 .

[0025] Specifically, a push frame 19 is fixedly installed on the top left side of the trolley 1.

[0026] The arrangement of the push frame 19 facilitates the staff to move the entire device.

[0027] Specifically, the hose 5 includes a first hose 20, a hard tube 21, and a second hose 22. The bottom end of the first hose 20 is fixedly connected to the output end of the water pump 4, the bottom end of the hard tube 21 is fixedly connected to the top of the first hose 20, the top of the hard tube 21 is connected to the left end of the second hose 22, the right end of the second hose 22 is connected to the nozzle 6, and a cross bar 23 is fixedly installed on the right end of the outer wall of the hard tube 21, and the right end of the cross bar 23 is fixedly installed on the left end of the outer wall of the outer ring 11.

[0028] Specifically, the first hose 20 is a corrugated tube.

[0029] The outer ring 11 and the hard tube 21 are connected by arranging a cross bar 23 , so that the position of the hard tube 21 can move up and down along with the threaded seat 9 .

[0030] By configuring the first hose 20 as a corrugated tube, the first hose 20 can be prevented from being tangled due to its own compressible and stretchable properties.

[0031] Working principle: When adjusting the height of the nozzle 6, the screw motor 7 controls the screw 8 to rotate. Since the vertical pipe 13 is fixed on the outer shell of the screw motor 7, the vertical pipe 13 is in a fixed state, and the internal thread ring 16 and the outer ring 11 are an integrated structure. The limiting wheel 12 on the inner side of the outer ring 11 rolls in the wheel groove 14 on the outer side wall of the vertical pipe 13, so the rotation of the screw 8 can only drive the internal thread ring 16 and the outer ring 11 to move up and down, thereby adjusting the height of the nozzle 6.

[0032] When dust is to be reduced, the whole is moved to the position to be dusted, and the water pump 4 is turned on, the water pump 4 draws water from the water tank 3 and sprays water mist through the nozzle 6 to reduce dust.

[0033] The driving power switches of the water pump 4, the screw motor 7 and the electric push rod 18 can all be arranged on the push frame 19, which is convenient for the staff to operate.
