Description

Technical Field

[0001] This utility model relates to the field of concrete paving technology, specifically to a concrete paving auger device. Background Technology

[0002] Concrete paving equipment is a mechanical device used to spread concrete evenly and smoothly on the ground. It spreads the mixed concrete evenly on the roadbed or other ground to form the required thickness and width. Automated paving equipment can greatly improve the efficiency of concrete paving, reduce manual operation, and shorten the construction cycle. Through mechanized operation, it ensures that the concrete surface is flat and reduces construction errors. It is widely used in the construction of large concrete structures such as roads, bridges, airport runways, and parking lots.

[0003] Chinese Patent Publication No. CN222313724U, entitled "Concrete Paver," includes a tracked walking unit, a main body connected to the tracked walking unit, a screw conveyor connected to the main body, a track frame connected to the main body, a paving mechanism mounted on the track frame, a mixing device connected to the main body, and a belt conveyor mounted on the main body. The concrete paver provided by this invention can replace manual concrete paving work on tunnel floors, greatly improving the quality and efficiency of concrete paving, and can adapt to concrete paving work under undulating tunnel floor conditions.

[0004] The shortcomings of the above solution are as follows: Although the above solution can be used for concrete paving, it relies on the tracked walking unit and fixed paving mechanism, which makes it less adaptable to the local unevenness of the roadway floor, which can easily lead to uneven paving thickness. In addition, the paving mechanism (such as scraper) is usually fixed in height or manually adjustable, which cannot respond to changes in the height of the concrete surface in real time, resulting in a large error in flatness. Utility Model Content

[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0007] A concrete paving auger device, including a chassis;

[0008] A mounting box is fixedly connected to the bottom of the frame, and two motors are connected inside the mounting box. The drive ends of the two motors are rotatably connected to wheels.

[0009] The mounting box is connected to a connecting bracket via a hinge. An adjustment mechanism is connected between the connecting bracket and the vehicle frame. The adjustment mechanism includes an electric cylinder 1 connected to the vehicle frame. A telescopic rod is connected to the drive end of the electric cylinder 1.

[0014] As a further embodiment of this utility model: the vibrating plate is an electrically operated high-frequency vibrating plate.

[0015] As a further embodiment of this utility model: two sets of fixing frames are fixedly connected to the other side of the vehicle frame. The two sets of fixing frames are respectively arranged on both sides of the same side of the vehicle frame. An electric cylinder is fixedly connected to the end of the fixing frame away from the vehicle frame. A lifting frame is connected to the driving end of the electric cylinder.

[0019] The beneficial effects of this utility model are:

[0020] 1. After the auger device of this utility model delivers concrete, the electric cylinder one adjusts the angle of the connecting bracket via the telescopic rod, that is, adjusts the height of the vibrating plate and scraper off the ground to adapt to different paving thicknesses. The roller is adjusted by the lifting frame via the electric cylinder two, so that the roller is close to the concrete surface. The wheel rotates, driving the roller to rotate, compacting and leveling the concrete, eliminating local height differences, and preventing material accumulation by the subsequent scraper. The vibrating plate is driven by the motor to vibrate up and down, further compacting the concrete and expelling air bubbles. By adjusting the angle of the connecting bracket via the electric cylinder and telescopic rod, the height of the vibrating plate and scraper off the ground can be adjusted, thereby adapting to the paving of concrete of different thicknesses, eliminating local height differences, and ensuring the flatness of the concrete surface.

[0021] 2. This utility model uses a horizontal adjustment rod to adjust the tilt of the vibrating plate to ensure it is parallel to the concrete surface. The scraper is fixed behind the vibrating plate, and its angle is adjusted by the connecting frame to scrape away excess concrete, achieving final flatness. The scraper and the vibrating plate are linked to ensure that the surface is immediately flattened after vibration, avoiding rebound. The horizontal adjustment rod precisely adjusts the tilt of the vibrating plate to ensure that it is parallel to the concrete surface, thereby achieving a higher degree of flatness. The scraper is fixed behind the vibrating plate, and by adjusting its angle, it can effectively scrape away excess concrete, ensuring a clean and flat surface. Attached Figure Description

[0030] A vibrating rod bracket 2 is fixedly connected to one side of the frame 1, and two sets of fixing brackets 11 are fixedly connected to the other side of the frame 1. The two sets of fixing brackets 11 are respectively arranged on both sides of the same surface of the frame 1.
