Preferably, the rubber sleeve is sleeved on the water pipe body clamped in the clamping mechanism.
The utility model provides a pair of dust fall instrument is used in highway construction, beneficial effect lies in: cooperate with the shower nozzle through setting up reciprocating motion mechanism, water supply mechanism passes through the hose and annotates water in to the water pipe, and spout from the shower nozzle and form water smoke, thereby realize the dust fall, in this moment, reciprocating motion mechanism drives the rack and is straight reciprocating motion, rack drive gear is periodic just reversing, and then drives the periodic just reversing of pivot, thereby drive the shower nozzle horizontal hunting on the water pipe, and then make shower nozzle spun water smoke can cover wider construction area, just so can obtain better dust fall effect.
Fig. 1 is a first schematic structural diagram of a dust-settling tool for highway construction provided by the utility model;
fig. 2 is a schematic structural diagram of a dust-settling tool for highway construction according to the present invention;
fig. 3 is a schematic view of a partial structure at a in fig. 2.
In the figure: the device comprises a vertical plate 1, a transverse plate 2, a rotating shaft 3, a lower arc-shaped clamping plate 4, an upper arc-shaped clamping plate 5, a water pipe 6, a spray head 7, a hose 8, a gear 9, a driving motor 10, a rack 11, a sliding sleeve 12, a guide rod 13, a fixing plate 14, a connecting rod 15 and a cross rod 16.
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-3, a dust fall instrument is used in highway construction, including riser 1, 1 bottom fixed mounting of riser has the base, 1 upper portion fixed mounting of riser has diaphragm 2, rotatable mounting has the pivot 3 of vertical setting on diaphragm 2, 3 top fixed mounting of pivot have fixture, the water pipe 6 that the level set up is held in the fixture, fixture includes lower arc splint 4, go up arc splint 5, lower arc splint 4, go up through bolt and nut fixed connection together between the arc splint 5, lower arc splint 4, the centre gripping has water pipe 6 that the level set up between the last arc splint 5. The pipe body of the water pipe 6 clamped in the clamping mechanism is sleeved with a rubber sleeve. The effect of rubber sleeve lies in preventing that fixture from crushing water pipe 6, leads to water pipe 6 to break, causes the water waste.
Shower nozzle 7 is installed to 6 one end of water pipe, the hose 8 that is linked together with it is installed to 6 other ends of water pipe, hose 8 is connected with water supply mechanism, 3 bottom transmission in pivot are connected with drive module, drive module includes gear 9, 3 bottom fixed mounting in pivot have gear 9, gear 9 one side is provided with rack 11 with it engaged with, rack 11 both sides set up one respectively with its parallel guide arm 13, all the cover is equipped with a sliding sleeve 12 on the guide arm 13, the equal fixed connection of sliding sleeve 12 is on rack 11, the equal fixed plate 14 of fixed plate 14 at the guide arm 13 both ends, the equal fixed connection of fixed plate 14 is on riser 1, the transmission of rack 11 is connected with reciprocating motion mechanism. The two guide rods 13 mainly serve to limit the movement of the rack 11, so that the rack 11 can only move linearly along the two guide rods 13.
When the utility model is used, the device is placed in a construction area, so that the spray head 7 is aligned to the area needing dust fall, and the base is fixed on the ground; then starting a water supply mechanism, injecting water into the water pipe 6 through a hose 8 by the water supply mechanism, and spraying the water from a spray head 7 to form water mist, so as to realize dust fall; meanwhile, the reciprocating mechanism drives the rack 11 to do linear reciprocating motion, the rack 11 drives the gear 9 to periodically rotate forwards and backwards, and then the rotating shaft 3 is driven to periodically rotate forwards and backwards, so that the spray head 7 on the water pipe 6 is driven to swing left and right, and further the water mist sprayed by the spray head 7 can cover a wider construction area, and a better dust settling effect can be obtained.
