[0002] A polyurethane floor refers to a floor made of polyurethane floor coating. The polyurethane floor coating is a type of floor coating with a polymer compound containing recurring urethane characteristic units in the molecular main chain structure as the film-forming substance, and is suitable for floor coatings with anti-slip, anti-corrosion, and wear-resistant requirements in various industrial and mining enterprise workshops, parking lots, sports fields, etc. The new generation of polyurethane floors mainly replaces the epoxy floors, and has advantages such as better wear resistance, flexibility, and convenient construction.

The mixing tank is fixedly installed on the top surface of the base, and a mixing motor is fixedly installed at the center position of the top surface of the mixing tank, and a mixing paddle is arranged inside the mixing tank. Beneficial effects: The utility model adopts a scraping plate and a mortar pump. When in use, the staff can put the raw materials of the waterborne polyurethane mortar floor coating and water into the mixing tank, start the mixing motor to drive the mixing paddle to rotate for mixing. After mixing, the device can be pushed, the mortar pump and the driving motor are turned on. The mortar pump pumps the mixed waterborne polyurethane mortar floor coating, injects it into the discharge pipe, and sprays it out along the spraying head onto the ground. The driving motor drives the scraping plate to rotate, and scrapes the sprayed waterborne polyurethane mortar floor coating flat, thus saving the trouble of manual coating, improving the construction efficiency of the waterborne polyurethane mortar floor coating, and improving the convenience of use.

[0004] Although the above patent can mix the materials in the mixing tank, the mixing paddle is used for single-direction mixing, and the obtained mixing effect may be poor. At the same time, the direction of the spraying head cannot be changed. When the materials sprayed by the spraying head are uneven and there is less material in some places, it is necessary to move the device again to spray the less material area again, thereby reducing the spraying and coating efficiency.

[0026] The effect achieved by the entire embodiment 2 is that when it is necessary to stir the waterborne polyurethane mortar floor coating in the stirring cylinder 610, the first motor 608 is turned on. The first motor 608 drives the second rotating rod 605 to rotate. The second rotating rod 605 then drives the second stirring rod 606 to rotate and stir in the stirring cylinder 610. At the same time, the second rotating rod 605 drives the second gear 607 to rotate during the rotation process. The second gear 607 then drives the first gear 604 and the first rotating rod 602 to rotate in the reverse direction. The first rotating rod 602 drives the first stirring rod 603 to rotate in the reverse direction in the stirring cylinder 610.

The second motor 707 drives the rotating tube sleeve 704 to rotate by a certain angle, so that the angle of the spray head 706 rotates to a suitable angle. Then the material pump 701 is turned on, so that the ground with less coating can be sprayed.

[0027] Working principle: First, add the coating into the mixing drum 610 through the feeding port 609. When it is necessary to mix the waterborne polyurethane mortar floor coating in the mixing drum 610, turn on the first motor 608. The first motor 608 drives the second rotating rod 605 to rotate. The second rotating rod 605 then drives the second stirring rod 606 to rotate and stir in the mixing drum 610. At the same time, the second rotating rod 605 drives the second gear 607 to rotate during the rotation process. The second gear 607 then drives the first gear 604 and the first rotating rod 602 to rotate in the reverse direction. The first rotating rod 602 drives the first stirring rod 603 to rotate in the reverse direction in the mixing drum 610. The first stirring rod 603 and the second stirring rod 606 are arranged to rotate and stir in the mixing drum 610 in the reverse direction, thereby improving the mixing effect of the coating in the mixing drum 610 and making the coating mix evenly. When the coating is mixed evenly, the material pump 701 can be turned on. The material pump 701 pumps the coating in the mixing drum 610 into the discharge pipe 705. The discharge pipe 705 then sprays the coating onto the ground through the spray head 706. Then, turn on the electric push rod 4. The electric push rod 4 drives the coating scraper 5 to descend to an appropriate height. After that, pull the device through the moving wheels 2 and the pull rod 8 to move, so that the coating is evenly sprayed on the ground. At the same time, during the moving process, the coating scraper 5 will scrape the coating on the ground flat. When it is found that the coating on the ground is uneven and there is less material on some parts of the ground, the second motor 707 can be turned on. The second motor 707 drives the rotating pipe sleeve 704 to rotate by a certain angle, so that the angle of the spray head 706 is rotated to an appropriate angle. Then, turn on the material pump 701 again, so that the ground with less coating can be sprayed without moving the device again, thereby improving the spraying and coating efficiency.
