In addition; Along with the continuous development of bituminous material science and construction Craft, the situation that usually exists multiple bituminous material conversion to use is for example after once spilling cloth ordinary hot pitch; Construction next time may adopt rubber asphalt or polymer modified asphalt to spill cloth; Because rubber asphalt or polymer modified asphalt viscosity are bigger, adopt and spill the uniformity requirement that the nozzle of cloth ordinary hot pitch same size does not reach job specfication, present method is the nozzle that is equipped with two cover different sizes; One cover low discharge nozzle is exclusively used in and spills cloth ordinary hot pitch; Another set of big flow nozzle is exclusively used in the cloth that spills of asphaltum with high viscosity materials such as rubber asphalt or polymer modified asphalt, when needing conversion to use different bituminous materials, and the nozzle that field replacement is corresponding.
Be generally 3.5m-7m at the pitch sprinkling car of usefulness or the cloth width that spills of synchronous surface dressing car, the quantity of every cover nozzle is about 28-70, changes very inconvenience, inefficiency.
Summary of the invention
The objective of the invention is the deficiency to above-mentioned prior art, but a kind of economical and efficient is provided, variable type pitch spray bars that the fast adaptation different pitches material that economizes on resources spills the cloth requirement.
For solving the problems of the technologies described above; The present invention provides a kind of variable type pitch spray bars; It mainly is made up of spray line, pitch dispenser valve, low discharge nozzle, big flow nozzle, and said pitch dispenser valve has two rows in said spray line equal intervals mounting arrangements; Said low discharge nozzle is installed on the row wherein, and said big flow nozzle is installed on another row; The opening of said low discharge nozzle, said big flow nozzle all with the said spray line axis identical angle that tilts.
Preferably, said pitch dispenser valve is opened or closed by pneumatic execution architecture, and the spacing of arranging is 100-200mm;
Preferably, under the equal spray pressure, the flow of said low discharge nozzle is 1/4 ~ 2/3 of a said big flow nozzle;
Preferably, said low discharge nozzle and said big flow nozzle are fan nozzle, and spraying segment angle is 60 ° ~ 85 °, with the angle of inclination of said spray line axis be 15 ° ~ 30 °.
Spill the cloth amount when spilling cloth when spilling change on the cloth width, only need to open the big flow nozzle and the low discharge nozzle of respective numbers, can reach distributing rationally of asphalt content according to certain combination according to the pavement disease situation.And when conversion bituminous material of different nature is constructed; Do not need operating personnel's field replacement nozzle; For example open the low discharge nozzle separately and can realize the cloth that spills of ordinary hot pitch; Open big flow nozzle separately and then can realize the cloth that spills of asphaltum with high viscosity such as rubber asphalt or polymer modified asphalt, significantly reduced the time before the construction, improved economy and operating efficiency.
