Description
Technical field
The present invention relates to mist stake technical field, the Self-spraying mist stake of specially a kind of construction site.
Background technique
Will appear many vehicle drivings at the construction field (site), however the dust of construction site generally all compare it is more, due to
A large amount of soil is certainly existed at the construction field (site), with the wind and as the traveling of vehicle can raise a large amount of ash after clay and drying
Dirt, these dusts can not be eliminated thoroughly, and current most important mode is exactly depositing dust processing, and common method mainly passes through watering
Vehicle sprinkles water to ground, but the more wasteful water of this mode, and ground is dry than very fast, and watering frequency is also just relatively
The mode of height, depositing dust processing further includes spray truck and spraying stake, and wherein spray truck is not in daily use, a wide range of mainly for high-altitude
Carry out depositing dust, and spray truck in the process of moving itself also can fugitive dust, and limitation is bigger in use for spraying stake, right
Many in the dust that vehicle is rolled, the dust in low latitude generates greatly adverse effect for the health of staff, and
Current spraying stake majority is timing atomizing de-dusting, carries out depositing dust, in response to this, applicant in the fugitive dust more period
Sprout the idea that research Self-spraying is sprayed stake, it can it is directed to low latitude fugitive dust, it is general in the mist stake of the timely self-spray water mist in source

The surface of spraying stake, water flow are flowed to by spraying stake on the surface of dust removal bag and connection stake, and the vehicle travelled at this time is rushed to both sides
The dust hit directly rushes on connection stake and dust removal bag, and the lower surface of spraying stake suppresses dust, so that dust is confined to
Between spraying stake, connection stake, dust removal bag and bottom stake, dust touches the spraying stake for being chronically at moisture state, connection stake, dust removal
It on bag and bottom stake surface, no longer flies up, the dust rolled can be reduced by having reached, and reduced the workload of mist stake, improved dedusting
Efficiency.
(3) present invention plays water spring by setting, and water can strike in jet port when spraying by each jet port
On the bullet water spring in portion, playing water spring can shake under the influence of the impact force, the shake that the bullet water spring frequently shaken can be unordered by water column,
The random shape of the water column of shake, which strikes each corresponding five ribs impact block and sprays, to be dissipated on mist block, and the water column of shake can subtract
Few five rib impact blocks and injection dissipate the water that mist block is locally hit, so that water dispersion impinges upon five rib impact blocks and sprays scattered mist block
Each position, nebulization efficiency is higher.
(4) the bottom stake in the present invention, spraying stake and connection stake can also be played the role of limiting vehicle pass-through, for vehicle
Size designs the size of mist stake, and can reduce car speed in conjunction with deceleration strip, reduction of speed while improving construction site safety
The dust rolled of vehicle is reduced, so that the general spraying most of spray regimes of stake of effective solution are wider, without specific aim,
Mainly a wide range of injection carries out depositing dust, and spraying time is not easy control, and water resource expends larger problem.
