[0025] See also Figure 1-5The utility model provides a technical solution: a paving machine, comprising: an equipment body 1, the outer surface of the equipment body 1 near the bottom is fixedly connected to two fixing columns 2, the inner surfaces of the two fixing columns 2 are movably embedded with tooth plates 3, and also comprising: two gears 5, the inner surfaces of the two gears 5 are fixedly installed with a rotating shaft 6, the bottom outer surfaces of the two tooth plates 3 are fixedly connected with a paving block 4, the outer surface of the rotating shaft 6 is fixedly installed with a turntable 7, the side of the turntable 7 away from the rotating shaft 6 is fixedly connected with a handle 8, the outer surface of the rotating shaft 6 is movably sleeved with two shaft sleeves 9, the outer surfaces of the two shaft sleeves 9 are fixedly connected with a fixing rod 10, and the fixing rod 10 is fixedly connected to the bottom outer surface of the equipment body 1. In this way, when it is necessary to make the flatness, slope and thickness of the paved road meet the process requirements, the paving block 4 can be raised and lowered by rotating the handle 8, thereby adjusting the thickness of the paved road, so that the flatness, slope and thickness of the road meet the process requirements, thereby improving the service life, bearing capacity and drainage performance of the road.

[0026] like Figure 1-5 As shown, two positioning plates 11 are fixedly connected to the side of the equipment body 1 away from the two fixed columns 2, connecting rods 12 are movably embedded in the inner surfaces of the two positioning plates 11, baffles 13 are fixedly connected to the outer surfaces of the two connecting rods 12, transmission plates 14 are fixedly connected to the sides of the two connecting rods 12 away from the two baffles 13, connecting rods 2 15 are fixedly connected to the outer surfaces of the two transmission plates 14, springs 16 are movably sleeved on the outer surfaces of the two connecting rods 12, and working blocks 17 are fixedly connected to the outer surfaces of the two connecting rods 2 15, so that the road paver can move in a predetermined direction and always keep parallel to the ground, and the paving of curved roads is reduced, thereby improving the road paving efficiency.

[0027] like Figure 1-5 As shown, two gears 5 are meshed and connected to the outer surfaces of the two tooth plates 3. The gears 5 can drive the tooth plates 3 to extend from the inside of the fixed column 2, so that the paving blocks 4 are close to the ground, and then the thickness of the paved road is adjusted so that the road can meet the process requirements.

[0028] like Figure 1-5 As shown, a handle 20 is fixedly connected to one side of the equipment body 1 near the top, and the handle 20 can provide power for the movement of the paver, so that the paver moves in a predetermined direction.

[0029] like Figure 1-5 As shown, the outer surfaces of the two working blocks 17 are fixedly connected with the second rotating shaft 18, and the outer surfaces of the two second rotating shafts 18 are movably sleeved with guide wheels 19. The second rotating shaft 18 can provide a good working environment for the guide wheels 19 and improve the service life of the guide wheels 19.

[0030] like Figure 1-5As shown, the two positioning plates 11 are fixedly connected to the sides away from the two connecting rods 12 with a fixing plate 21, and the two transmission plates 14 are fixedly connected to the sides close to the top with a sliding rod 23. The sliding rod 23 can prevent the transmission plates 14 from derailing when moving, thereby increasing the service life of the transmission plates 14.

[0031] like Figure 1-5 As shown, two fixed plates 21 are provided with a slide groove 22 on one side close to the two slide bars 23. The two slide bars 23 are movably embedded in the inner surfaces of the two slide grooves 22. The slide grooves 22 can limit the moving trajectory of the slide bars 23, thereby preventing the slide bars 23 from derailing and affecting the use of the equipment.

[0032] like Figure 1-5 As shown, two springs 16 are fixedly connected to the outer surfaces of the two transmission plates 14, and one end of the two springs 16 away from the two transmission plates 14 is fixedly connected to the outer surfaces of the two positioning plates 11. The spring 16 can make the transmission plate 14 drive the connecting rod 2 15 to move in the opposite direction, and then make the working block 17 drive the guide wheel 19 to move in the opposite direction through the rotating shaft 2 18, so that the guide wheel 19 can always fit with the side of the road template, and then when the road is curved, the guide wheel 19 can also fit with the road template.

[0033] Working principle: This equipment is a paver. When the paver is paving a curved path, first move the paver to the working position, then pour the paving material into the template of the area to be paved, manually pull the transmission plate 14, so that the guide wheel 19 on the transmission plate 14 is close to the side of the template for paving the road. When the transmission plate 14 moves, the transmission plate 14 drives the working block 17 to move through the connecting rod 15, and the working block 17 moves the guide wheel 19 through the rotating shaft 18, so that the guide wheel 19 fits the template, and the spring 16 will deform with the transmission plate 14. One side of the spring 16 is connected to the positioning plate 11 so that the spring 16 obtains elastic potential energy. When the paver moves, the spring 16 releases the elastic potential energy so that the guide wheel 19 is always in contact with the template for paving the road, and the connecting rod 12 moves with the transmission plate 14. The baffle 13 can prevent the connecting rod 12 from being disconnected from the positioning plate 11 when moving, causing the connecting rod 12 to fall off and affect the use of the equipment. The cooperation between the slide groove 22 on the fixed plate 21 and the slide rod 23 can prevent the transmission plate 14 from tilting when moving, affecting the use of the equipment. In this way, the road paver can be moved in a predetermined direction and always kept parallel to the ground, which reduces the difficulty of paving curved roads and improves the road paving efficiency. When the thickness of the paved road needs to be adjusted, the handle 8 is manually rotated, and the handle 8 drives the turntable 7 to rotate, and the turntable 7 drives the shaft 6 to rotate, and the shaft 6 drives the two gears 5 to rotate, and the two gears 5 drive the two tooth plates 3 to move out of the inside of the two fixed columns 2, so that the two tooth plates 3 drive the paving blocks 4 to move up and down, and the tooth plates 3 are provided with a scale, so that the paving can be controlled. To adjust the thickness of the road, employees manually pull handle 20 to move the equipment body 1 in a predetermined direction to pave the road. The cooperation of the fixed rod 10 and the sleeve 9 can provide a good working environment for the rotating shaft 6. In this way, when the flatness, slope and thickness of the paved road need to meet the process requirements, the handle 8 can be rotated to raise and lower the paving block 4, thereby adjusting the thickness of the paved road so that the flatness, slope and thickness of the road meet the process requirements to improve the service life, bearing capacity and drainage performance of the road.
