Abstract

The utility model discloses a spray pipe for a foldable multi-overlapping asphalt spraying device. The spray pipe comprises a spray pipe main body and a row of multiple spray heads on the spray pipe main body, wherein the distance from each spray head to the ground is H; furthermore, all the spray heads rotate for the same angle phi in the same direction; except the spray heads at two ends, the spraying fan-shaped angle of each of the other spray heads is 2 alpha, the uniform spacing distance is b, and the relationship among various parameters is that 2Htanalphacosphi=3b; and the distance between each of the spray heads at two ends and the spray head adjacent to each of the spray heads at two ends is b/2, the spraying fan-shaped angle of each of the spray heads at two ends is 2 alpha', and the relationship among various parameters is that 2Htanalpha'cosphi=2b. The spray pipe for the foldable multi-overlapping asphalt spraying device disclosed by the utility model has the benefits that the distance between the spray heads at two ends is adjusted to be half of the original distance; the spraying fan-shaped angle is decreased, therefore, a sprayed asphalt fan-shaped surface and an asphalt fan-shaped surface sprayed by the adjacent spray head form tri-overlapping and double-overlapping effects; the asphalt spraying quality is greatly increased; and multi-overlapping effects can be realized at two ends.

Description

A kind of jet pipe for the multiple folded pitch sprinkling device of foldable

Technical field

The utility model relates to a kind of jet pipe, particularly a kind of novel jet pipe for the multiple folded pitch sprinkling device of foldable.

Background technology

The pitch that is used for each the shower nozzle ejection on the pitch jet pipe of pitch sprinkling device is fan shape, and segment angle is 2 α, and shower nozzle overhead highly is H, as shown in Figure 1.The actual spray width L=2Htan α of each shower nozzle.

The pitch of the adjacent two shower nozzles ejection of this pattern can form interference aloft, causes the laterally inhomogeneous of pitch.Because the pitch of ejection is fan-shaped, so the φ that only shower nozzle need be rotated to an angle then can solve the pitch interference problem, shower nozzle anglec of rotation schematic diagram as shown in Figure 2.After the shower nozzle rotation, single shower nozzle spray width B=2Htan α cos φ in the horizontal, the relation between each parameter is as shown in Figure 3.

The spray area of traditional last nozzle of pitch spray line two ends not exclusively and adjacent nozzle form and multiplely foldedly spill cloth, it is that substance is folded and spilt cloth that 1/3 area is generally arranged, effect is shown in Fig. 4,5,6.Like this in road spreading, least significant end will cause pitch sprinkling inhomogeneous, problem such as the pitch sprinkling amount is not enough causes the road surface defective.

The utility model content

Goal of the invention of the present utility model is: at the problem of above-mentioned existence, provide a kind of jet pipe for the multiple folded pitch sprinkling device of foldable, overcome pitch that last nozzle of two ends causes spray inhomogeneous, spill the not enough problem of cloth amount.

The technical solution adopted in the utility model is such: a kind of jet pipe for the multiple folded pitch sprinkling device of foldable, comprise the jet pipe main body with and on one row some shower nozzles, all shower nozzles are H apart from the height on ground, and all rotate same angle φ to equidirectional, other shower nozzles of removing the two ends shower nozzle spray fan-shaped angle be 2 α and evenly spacing distance be b, pass between each parameter is 2Htan α cos φ=3b, distance between the shower nozzle at the two ends shower nozzle adjacent thereto is b/2, it sprays fan-shaped angle is 2 α ', and the pass between each parameter is 2Htan α ' cos φ=2b.

Rule of thumb, remove other shower nozzles outside the shower nozzle at two ends and spray segment angle 2 α and get 60 °, all nozzle rotating angle φ get 30 °.When choosing these two parameters, the effect that shower nozzle sprays is fine.

In sum, owing to adopted technique scheme, the beneficial effects of the utility model are: the sprinkler spacing at two ends is adjusted into original half, the sprinkling segment angle diminishes, Pen Chu pitch sector can form triple superimposition two overlapping effects with the pitch sectorial area of adjacent shower nozzle ejection like this, and the sprinkling quality that improves pitch greatly can realize multiple folded effect at two ends.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is done detailed explanation.

Most preferred embodiment: as shown in Figure 7, a kind of jet pipe for the multiple folded pitch sprinkling device of foldable, comprise jet pipe main body 1 with and on one row some shower nozzles 2, all shower nozzles 2 are H apart from the height on ground, and all rotate same angle φ to equidirectional, the fan-shaped angle of other shower nozzles 2 sprinklings of removing two ends shower nozzle 2 is that 2 α and even spacing distance are b, pass between each parameter is 2Htan α cos φ=3b, distance between shower nozzle 2 shower nozzles 2 adjacent thereto at two ends is b/2, it sprays fan-shaped angle is 2 α ', and the pass between each parameter is 2Htan α ' cos φ=2b.

Rule of thumb, remove other shower nozzles 2 outside the shower nozzle 2 at two ends and spray segment angles 2 α and get 60 °, all shower nozzle 2 anglec of rotation φ get 30 °.

In the present embodiment, described shower nozzle 2 has 36, realize on the road surface 4 meters spray width.

According to the spray effect shown in Fig. 7,8, the shower nozzle 2 on the limit does not increase the spray width on road surface as can be seen, and namely actual spray width is determined by the length of 34 shower nozzles.B is single shower nozzle spray width in the horizontal, B=2Htan α cos φ.As Fig. 4, realize three overlapping effect, then B=3b.So, realize the spray width on 4 meters on road surface, 33b+B=36b=4000mm, can calculate like this b=111.11mm, round and be 112mm.

According to three overlapping realization condition 2Htan α cos φ=3b, can calculate H=336mm, when namely shower nozzle overhead highly is 336mm, can realize the three overlapping cloth that spill.

After having determined H, φ, b, just can calculate α '=21 °, the shower nozzle 2 at two ends sprays segment angles 2 α '=42 °.

The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
