[0002] Polyurethane gravel material is a material with polyurethane as the only cementing material. Thermosetting liquid polyurethane is used as the binder in polymer concrete, and curing agents, aggregates and fillers are incorporated to make polymers.
[0003] During the paving process, it is necessary to spray polymers such as polyurethane on the road surface, and then evenly sprinkle gravel on the polymer. The fixation and adhesion of the gravel are achieved through the viscosity of the polymer to form a polyurethane road surface.
[0004] However, in the actual paving process, since the polymer needs to be melted at high temperature first and then sprayed, after the gravel is laid on the upper end of the polymer, the polymer is solidified by natural cooling, so that the gravel is fixedly adhered to the road surface. The temperature of the polymer is relatively high, and the natural cooling process is relatively long. And when the temperature of the polymer is too high, it is difficult to solidify immediately after spraying, resulting in a flowable state, so that the gravel flows in the polymer, and then wraps the gravel, resulting in the movement of the gravel after paving and unable to form a uniform polyurethane road surface.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0023] Please refer to Figures 1 to 4 , the present invention provides a technical solution:
[0024] Embodiment 1: A device for realizing uniform sprinkling and paving of polyurethane pavement mixture, including a sprinkling device. The sprinkling device is arranged on the mixing hopper 3. The upper end of the mixing hopper 3 is communicated with the silo 1. A mixing auger 7 for stirring the mixture is arranged in the inner cavity of the mixing hopper 3. The lower end of the mixing hopper 3 is provided with a discharge port 15. A spreading auger 9 facing the discharge port 15 is arranged at the front end of the mixing hopper 3.
[0025] By setting the mixing auger 7, the raw materials loaded in the silo 1 are fully mixed, and then discharged from the discharge port 15 and fall on the spreading auger 9. By using the rotation of the spreading auger 9, the crushed stone raw materials are evenly sprinkled on the melted polyurethane polymer.
[0026] The sprinkling device includes a water tank 4 and atomizing nozzles 6. The water tank 4 is fixed on the mixing hopper 3. The front end of the water tank 4 is connected with a plurality of groups of atomizing nozzles 6 distributed linearly through a water pipe 5. A guide inclined plate 20 is arranged at the lower end of the atomizing nozzle 6. The lower end of the guide inclined plate 20 extends to directly above the spreading auger 9. A water storage tank 11 with the same length as the discharge port 15 is arranged at the lower end of the guide inclined plate 20.
[0027] By setting up an atomizing nozzle 6 and a water tank 4, the water flow particles are reduced, so that the water droplets in the atomized state fall on the polyurethane polymer to achieve the purpose of cooling. By setting up a guide ramp 20 for receiving some of the water droplets in the atomized state, they are gathered into drops and gathered in the water storage tank 11. As the water flow gathers, the gathered water flow overflows to one side of the uniform spreading auger 9 and is evenly sprinkled on the discharged gravel, so that the gravel carries the water flow and falls on the polyurethane polymer. When the gravel contacts the polyurethane polymer, rapid heat transfer is achieved to achieve the purpose of sufficient cooling.
[0028] Embodiment 2: Based on embodiment 1, a silo 1 is installed on a muck truck, and a silo door 2 facing the upper end port of a mixing hopper 3 is provided on one side of the silo 1, and a plurality of groups of spaced-apart diversion baffles 13 are provided on the upper end of the mixing hopper 3.
[0029] By providing the silo 1 and the silo door 3, continuous feeding to the mixing hopper 3 is achieved to achieve the purpose of continuous paving. By providing the diversion baffle 13, preliminary diversion of the falling raw materials is achieved so that they fall evenly into the inner cavity of the mixing hopper 3, thereby improving the mixing degree of the raw materials by the subsequent mixing auger 7.
[0030] The mixing auger 7 and the spreading auger 9 are both driven by motors, and the mixing hopper 3 is provided with a plurality of vibration motors 12 located just below the discharge port 15 .
[0031] By providing the vibration motor 12, it is ensured that the discharge port 15 continuously vibrates and discharges materials, thereby avoiding the accumulation and blockage of crushed stones.
[0032] An adjusting frame 17 is rotatably mounted at the front end of the mixing hopper 3 , and the spreading auger 9 is mounted on the adjusting frame 17 . The upper end of the adjusting frame 17 is connected to the front end outer wall of the mixing hopper 3 through a first adjusting rod 8 .
[0033] The first adjusting rod 8 is provided to adjust the angle of the adjusting frame 17 so that the evenly spreading auger 9 faces the discharge port 15, so that the crushed stone material discharged after mixing falls on the evenly spreading auger 9, and is further broken up and evenly spread.
[0034] A rotatably mounted baffle plate 10 is disposed on the end of the discharge port 15 , and the outer side of the baffle plate 10 is connected to the outer wall of the mixing hopper 3 via a second adjusting rod 18 .
[0035] The baffle plate 10 is adjusted by the second adjusting rod 18 , thereby controlling the angle of the baffle plate 10 , thereby achieving control of the discharge amount of the discharge port 15 .
[0036] Embodiment 3: Based on Embodiment 2, an upper protective frame 19 fixed to the outer wall of the mixing hopper 3 is provided at the upper end of the guide inclined plate 20 , and the upper protective frame 19 includes a plurality of groups of atomizing nozzles 6 .
[0037] By setting the upper protective frame 19, not only the fixed installation of the diversion inclined plate 20 is realized, but also the atomizing nozzle 6 is wrapped to prevent the atomized water droplets from diffusing upward.
[0038] A diversion vertical plate 14 extending towards the uniform spreading auger 9 is vertically arranged at the lower end of the diversion inclined plate 20, and a plurality of obliquely long slots 21 are linearly distributed on the diversion inclined plate 20.
[0039] By setting the diversion vertical plate 14, the water flow that gathers and overflows can accurately fall on the uniform spreading auger 9, and the obliquely long slots 21 are used to gather and divert the water droplets so that they accurately fall into the water storage tank 11.
[0040] A horizontal plate is arranged between the diversion inclined plate 20 and the diversion vertical plate 14, the water storage tank 11 is arranged on the horizontal plate, and a notch groove 16 is arranged on one side of the water storage tank 11 close to the diversion vertical plate 14.
[0041] By setting the notch groove 16, it is ensured that the water flow in the water storage tank 11 overflows towards the side of the uniform spreading auger 9.
[0042] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
