Asphalt sprayer with functions of heating and adjusting height of nozzle

Abstract

The invention discloses an asphalt sprayer with functions of heating and adjusting the height of a nozzle. The asphalt sprayer comprises a rack; a storage tank is arranged on the upper surface of therack and is provided with a heating device; the heating device comprises an electric heating head, a heating tube and a thermal conductive plate; the heating tube is connected with the left side of the electric heating head, and the thermal conductive plate is arranged on the top of the heating tube; a transmission device is arranged at the right side of the storage tank; a spraying device comprises a first motor, a bevel gear, a screw rod, a support pillar, a nut sliding block, a spraying rod, the nozzle and a hose pipe; an output shaft of the first motor is connected with the screw rod by means of the bevel gear in a way of transmission; the right side of the nut sliding block is connected with the spraying rod, and the lower surface of the spraying rod is provided with the nozzle. The asphalt sprayer is additionally provided with the heating device, so that the temperature of asphalt is maintained to be within a normal operating range; the asphalt sprayer realizes the height adjustment of the nozzle, improves the spraying efficiency and quality and prolongs the service life of equipment.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to an asphalt spreader with the functions of heating and adjustable nozzle height. Background technique [0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid. It is liquid with a black surface and is soluble in carbon disulfide. Asphalt is a waterproof, moisture-proof and anti-corrosion organic gelling material. Natural bitumen is stored underground, and some form deposits or accumulate on the surface of the earth's crust. Asphalt is mainly used in coatings, plastics, rubber and other industries and paving roads. Asphalt pavement refers to various types of road surfaces paved with asphalt materials mixed with mineral materials. [0003] Asphalt spreader is a kind of black road surface machinery. After the gravel layer is paved and r...
