Abstract
Description
Technical Field
[0001] This utility model belongs to the field of road construction technology, and in particular relates to a uniform spraying device for sand-containing mist seal material. Background Technology
[0002] Sand-based mist seal is a material composed of modified emulsified asphalt or coal tar pitch-based materials, clay, and polymer additives, used in conjunction with sand. It is sprayed onto asphalt pavements using a specialized high-pressure spray truck, forming a thin layer to seal micro-cracks, prevent aggregate loss, and block moisture penetration. This slows down asphalt aging, lowers pavement temperature, maintains skid resistance, and significantly improves pavement appearance.
[0003] Because the sand-containing mist seal layer contains solid sand particles, these particles tend to settle in the storage tank during spraying, leading to uneven spraying. Furthermore, the high viscosity of the modified emulsified asphalt significantly increases the difficulty of spraying, further exacerbating the uneven spraying phenomenon. Utility Model Content
[0004] The purpose of this utility model embodiment is to provide a uniform spraying device for sand-containing mist sealing material, which aims to solve the problems mentioned in the background art.
[0005] This utility model embodiment is implemented as follows: a uniform spraying device containing sand mist sealing material includes a spraying truck, a storage tank installed on the spraying truck, a stirring assembly installed inside the storage tank, a mortar pump installed on the spraying truck, and a spraying assembly installed at the rear of the spraying truck. A fixing base and a mounting base are fixedly installed inside the truck bed. The storage tank is fixedly installed on the upper end of the fixing base. The storage tank includes an outer tank, an inner tank, and a heating wire. The inner tank is located inside the outer tank. A filling port is fixedly provided above the inner tank, and a discharge port is fixedly provided on the lower side of one end of the inner tank. The heating wire is spirally arranged on the outside of the inner tank. Connecting wires are fixedly connected to both ends of the heating wire. One end of the connecting wire passes through the outer tank and extends to the outside to connect with the power supply equipment. The stirring assembly includes a stirring motor, a rotating rod, and a stirring paddle. The stirring motor is fixedly installed in the middle of one end of the outer tank. The main shaft of the stirring motor is fixedly connected to the rotating rod. The two ends of the rotating rod are movably located at both ends of the inner tank. The stirring paddle is fixedly installed on the outside of the rotating rod. The mortar pump has a pump inlet and a pump outlet fixedly arranged on both sides. The pump inlet is fixedly connected to the discharge port.

[0013] 2. The present invention provides a uniform spraying device for sand-containing mist sealing material. Through the setting of the heat insulation layer, the mist sealing material is kept warm, heat loss is reduced, heating wire energy consumption is reduced, and energy is saved.
[0014] 3. The present invention provides a uniform spraying device for sand-containing mist sealing material.
