Embodiment Construction

[0022] Such as figure 1 As shown in -5, a buried retractable nozzle includes an inner cylinder 1, an outer sleeve 2, an annular spring 4 and a bottom fixed warehouse 3, and the bottom fixed warehouse 3 is fixedly connected to the lower end of the outer sleeve 2 , The bottom of the outer casing 2 is welded with a circular connection plate, and the circular connection plate is connected with the bottom fixed warehouse 3 through hexagonal bolts 15 . The four corners of the bottom plate of the bottom fixed storehouse 3 are respectively provided with screw holes, which are used to bolt the bottom of the installation pit.

[0023] The inner cylinder 1 can be plugged into the outer sleeve 2 in a sealed and sliding manner up and down. The top of the outer sleeve 2 is provided with a sealing rubber ring. The outer wall of the inner cylinder 1 is in sliding and sealing contact with the sealant. The inner cylinder 1 The top of the top is fixed with an upper cap 5, and the diameter of th...

Abstract

The invention discloses an embedded extension nozzle in the technical field of pavement spraying. The embedded extension nozzle comprises an inner-layer cylinder, an outer-layer sleeve, an annular spring and a bottom fixed bin; multiple upper-layer spraying holes and multiple lower-layer spraying holes communicating with an inner cavity of the inner-layer cylinder are formed in the outer wall of the inner-layer cylinder; after the power failure of an electromagnet, the inner-layer cylinder slides down to the upper-layer spraying holes and the lower-layer spraying holes for closing in the outer-layer sleeve; and after the electromagnet is electrified, the inner-layer cylinder upwards slides to the upper-layer spraying holes and the lower-layer spraying holes for extension out of the outer-layer sleeve. The nozzle shrinks underground in an idle state; the spraying holes automatically extend out of the ground during working; liquid is sprayed near the ground to achieve lower influence ontraffic; and the embedded extension nozzle is wide in spraying coverage and suitable for such length distances as four lanes, six lanes and eight lanes.

Description

technical field [0001] The invention relates to the technical field of road surface spraying, in particular to an underground retractable nozzle. Background technique [0002] At present, the buried retractable nozzle is represented by the American Rain Bird retractable rotary nozzle, but this type of nozzle has a small spray distance, a large spray elevation angle, and a long spraying time for the same coverage area, which cannot meet the needs of rapid, safe and uniform automatic spraying on the road. . [0003] Based on this, the present invention designs a buried retractable nozzle to solve the above problems. Contents of the invention [0004] The object of the present invention is to provide a buried retractable nozzle with a large spray coverage area. [0005] In order to achieve the above object, the present invention provides the following technical solutions: a buried retractable nozzle, including an inner cylinder, an outer sleeve, an annular spring and a bott...
