Abstract

The utility model relates to an edge nozzle for asphalt distribution, which belongs to the technical field of road construction devices and comprises an injection port, a middle cavity and a nozzle, which are connected in sequence and are communicated internally, wherein a central nozzle is arranged on the central bottom surface of the nozzle, and a side spraying groove is arranged at one side of the nozzle. The edge nozzle of the utility model is operated conveniently, lateral deviation of asphalt distribution can be effectively reduced, the overall road surface performance can be improved, and the edge nozzle has wide market prospect.

Description

A kind of pitch sprays uses the limit nozzle

Technical field

The utility model relates to a kind of pitch flusher, and especially a kind of pitch sprays uses the limit nozzle, belongs to road construction device technique field.

Background technology

In road construction, when spilling priming oil and tack coat oil, all need to carry out pitch and spray with pitch sprinkling car, the cloth amount of laterally the spilling deviation of pitch sprinkling, three plies that sprayed by pitch guarantee.Three plies are meant that any point is all by the pitch overlapping covering simultaneously from three nozzle ejections on the ground.But for the pairing sprinkling of the nozzle on the limit at spray boom edge zone, adjacent have only a nozzle to form two superimposed with it, other regional pitch amount will be lacked one deck in the middle of being sprinkled upon this regional pitch amount and spray boom like this, thereby influence the construction quality on road surface, for bituminous paving stays potential safety hazard.

Therefore, can design a kind of pitch flusher,, become the technical barrier that those skilled in the art need to be resolved hurrily to overcome above-mentioned defective.

The utility model content

The utility model aims to provide a kind of pitch sprinkling limit nozzle, and it can reach the lateral deviation that reduces pitch sprinkling, the purpose that improves the road surface security performance by structural improvement.Its technical scheme that adopts is as follows:

This pitch sprays and mainly comprises with the limit nozzle: inlet, lumen and spout, and they connect and internal run-through in turn, and wherein said spout bottom center has center nozzle, and the one side has side and sprays groove.

Preferably, described center nozzle oval in shape.

Preferably, described side spray groove is a rectangular channel, and a minor face of rectangular channel and described center nozzle are joined.

Compared with prior art, the utlity model has following advantage:

1, easy realization simple to operate;

2, reduce the lateral deviation of pitch sprinkling;

3, the road surface security performance improves.

Description of drawings

Fig. 1: pitch of the present utility model sprays with limit structure of nozzle front view;

The bottom view of Fig. 2: Fig. 1;

Fig. 3: pitch of the present utility model sprays the application schematic diagram with the limit nozzle.

Among the figure: 1, spray arm; 2, spray the road surface; 3, limit nozzle; 4, inlet; 5, lumen; 6, center nozzle; 7, side spray groove; 8, spout.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing and example:

An embodiment of the present utility model as illustrated in fig. 1 and 2, this pitch sprays and mainly comprises with limit nozzle 3: inlet 4, lumen 5 and spout 8, they connect and internal run-through in turn, wherein spout 8 bottom center have center nozzle 6, the one side has side and sprays groove 7.

Center nozzle 6 substantially oblong-shaped shapes, side spray groove 7 is a rectangular channel, a minor face and the center nozzle 6 of rectangular channel are joined.

As shown in Figure 3, during practical application, equidistant (for example the phase mutual edge distance is L) arranges a plurality of nozzles on spray arm 1, and middle each nozzles spray scope is the 3L of symmetry; Unlike the prior art be, the nozzle on spray arm 1 both sides all also is a limit of the present utility model nozzle 3, and make side spray groove 7 towards spray arm 1 position intermediate, because the restriction of side spray groove 7, make under the situation of same pitch injection rate, the spraying range of limit nozzle 3 is littler than the scope of symmetrical 3L, having formed local deviator when spilling cloth sprays, though make limit nozzle 3 and an adjacent nozzles spray zone formation two superimposed on the limit of spray arm 1 to ground, but it is identical with arbitrary position of spray boom to be spread across this regional pitch amount, thereby reduced the lateral deviation of pitch sprinkling, improved the security performance of road surface integral body.Because only need to change on existing flusher two nozzles of position, limit, therefore operation is very simple, realizes easily, helps of the present utility model applying.

Evidence: this pitch sprays with the limit nozzle operation simple, can effectively reduce the lateral deviation of pitch sprinkling, improves the road surface overall performance.

With way of example the utility model is illustrated above, but the utility model is not limited to above-mentioned specific embodiment, all any change or modification of doing based on the utility model all belong to the claimed scope of the utility model.

Claims
