Abstract

The utility model provides a nozzle assembly, which mainly solves the problems of being hard to ensure the position because of being located by virtue of a sleeve, difficult to seal and easy to leak asphalt, and not easy to replace a nozzle, of the existing nozzle assembly. The nozzle assembly comprises a cylinder, a nozzle and a spray tube, wherein one end of the cylinder is inserted in a cavity in the spray tube and connected with a sleeve arranged in the spray tube, a push rod is arranged in the sleeve, one end of the push rod is connected with the piston of the cylinder, the other end of the push rod is connected with one end of a sealing cone head, and the other end of the sealing cone head is connected with a nozzle arranged at the outer side of the spray tube; and at least one open hole is formed in the sleeve. During replacement for the nozzle of the nozzle assembly, asphalt in the spray tube cannot be leaked; the nozzle assembly is sealed with the sleeve by virtue of the sealing cone head, so that the sealing is firm, and the nozzle can be freely replaced; and moreover, a nozzle angle location device is provided, so that the constant deflecting angle of the nozzle is ensured, and the spray uniformity is improved.

Description

Nozzle assembly
Technical field
The utility model relates to a kind of nozzle assembly, and this device is used for pitch sprinkling car or other pitch sprinkling equipment sprays pitch, belongs to the road building equipment technical field.
Background technology
Because the Jiao Tong Shi development of already advancing by leaps and bounds, mileage in highway open to traffic also increases year by year in recent years, construction quality is required more and more higher, and then to the performance requirement of construction machinery become better and better, functional requirement is more and more perfect.
The general nozzle that adopts carries out the pitch spraying operation in the construction of the highway machinery now, but existing nozzle assembly is owing to adopt the sleeve pipe Type of Welding, the nozzle location relies on the sleeve pipe location fully, it is bigger that sleeve pipe welds difficult error, be difficult to guarantee nozzle location, the pitch that can cause being sprayed to the road surface like this is inhomogeneous, influences pavement quality; Simultaneously, existing nozzle assembly then adopts sealing conehead and sealed nozzle, and sealing is difficulty, and spray line can be revealed pitch when changing nozzle.
Summary of the invention
The utility model provides a kind of nozzle assembly, and mainly solve existing nozzle assembly and relied on the sleeve pipe location to be difficult to guarantee the position, and the easy problem of revealing pitch, being difficult for changing nozzle of sealing difficulty.
Concrete technical solution of the present utility model is as follows:
This nozzle assembly comprises cylinder, nozzle and spray line, spray line comprises pipe and spray line outer tube in the spray line, pipe is arranged in the spray line outer tube in the spray line, and form cavity with the spray line outer tube, cylinder one end inserts sleeve pipe interior with being arranged on spray line in the interior cavity of spray line and is connected, and is provided with push rod in the sleeve pipe, and push rod one end is connected with the piston of cylinder, the push rod other end is connected with sealing conehead one end, and the sealing conehead other end is connected with the nozzle that is arranged on the spray line outside; Described sleeve pipe is provided with at least one perforate.
Above-mentioned cylinder is connected with casing threads.
Above-mentioned sleeve pipe one end is connected with spray line by last installation nut, and the sleeve pipe other end is connected with nozzle by down nut being installed.
Above-mentioned going up between the installation nut and the spray line outside is provided with O type circle, is provided with O type circle between the following installation nut and the spray line outside.
Advantage of the present utility model is:
The interior pitch of spray line can not leak when this nozzle assembly was changed nozzle, adopted sealing conehead and bobbin seal, and it is firm to seal, and nozzle can freely be changed, and has the nozzle angle positioner, guaranteed that the nozzle deflection angle is constant, improved and spilt the cloth uniformity.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail, as shown in Figure 1:
Referring to Fig. 1, this nozzle assembly comprises cylinder, nozzle and spray line, spray line comprises pipe and spray line outer tube in the spray line, pipe is arranged in the spray line outer tube in the spray line, and form cavity with the spray line outer tube, cylinder one end inserts sleeve pipe interior with being arranged on spray line in the interior cavity of spray line and is connected, and sleeve pipe is provided with at least one perforate.
Specifically, the spray line inner and outer pipes is divided into two cavitys with spray line, and pitch enters torus from the spray line inlet, flow to the spray line two ends through torus, enter spray chamber from the spray line two ends, perforate enters sleeve pipe on sleeve pipe, goes out through nozzles spray at last.
Be provided with push rod in the sleeve pipe, push rod one end is connected with the sealing conehead, and the other end is connected with cylinder piston.Piston motion promotes the sealing conehead by push rod, realizes the sealing of sealing conehead and bobbin seal face.
Cylinder is connected with casing threads, and sleeve pipe and spray line rely on to go up installs the nut installation.Nozzle and sleeve pipe are fixed by nut is installed down.Last installation nut is provided with O shape circle, is used to seal the plane.The lower plane sealing relies on the O type circle sealing of sleeve pipe lower end.
The utility model has mainly solved existing nozzle assembly and has relied on the sleeve pipe location to be difficult to guarantee the position, be difficult for changing nozzle, and the sealing difficulty is easily revealed the problem of pitch.
