[0002] Asphalt pavement refers to various types of pavement paved with road asphalt materials mixed into mineral materials. Asphalt binder improves the ability of paving aggregate to resist damage to the road surface caused by traffic and natural factors, making the road surface smooth, dust-free, waterproof and durable. At present, there are edge trimming equipment for asphalt pavement on the market. Usually, after the workers finish paving the road, protruding or uneven borders often appear on both sides of the roadside, which requires manual edge trimming at the same position, resulting in long trimming time and low work efficiency.

DETAILED DESCRIPTION

[0020] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, a road base trimming vibrating machine comprises: a frame beam 1, the frame beam 1 is a horizontal beam structure, and the two ends of the frame beam 1 are respectively vertically connected to one side with a stabilizing beam 2, and the middle of any one of the stabilizing beams 2 is vertically connected to a control handle 3, and the middle of the frame beam 1 is located between the two stabilizing beams 2 and is connected with a horizontal inner frame plate 4, and the inner frame plate 4 is provided with an engine 5 and a longitudinal slide 6; a roller 7, the roller 7 is sleeved on the outside of the inner frame plate 4, and the axis of the roller 7 is aligned with the two stabilizing beams 2 is parallel to the length direction, the roller roller 7 is provided with a bearing matched with the inner frame plate 4, and the roller roller 7 is connected with the engine 5 through the first transmission system; a cutting wheel 8, the cutting wheel 8 is arranged at the end of the roller roller 7 away from the frame beam 1, and the cutting wheel 8 is provided with a lifting shaft 9 extending into the roller roller 7, the lifting shaft 9 is matched with the longitudinal slide 6 through a slider 10, and a lifting device is provided between the slider 10 and the longitudinal slide 6; the bottom of each of the stabilizing beams 2 is provided with a supporting roller 11 through an adjusting bracket.

[0022] The above-mentioned road base trimming vibrating machine integrates the engine 5 inside the roller 7, thereby reducing its own external volume, and changes one end into an open structure, and is equipped with a cutting wheel 8, so that the cutting and shaping work of the edge of the asphalt pavement can be realized while the pavement is being laid, thereby greatly improving the work efficiency and ensuring a good cutting effect. During the working process, the construction personnel control the engine 5 through the control handle 3 and adjust its travel direction. When the cutting wheel 8 travels to a convenient position on the pavement, the lifting device is controlled by the control handle 3 to move the slider 10 down along the main slideway, so that the cutting wheel 8 descends and cuts and shapes the edge of the pavement. As the roller 7 moves forward, the cutting wheel 8 follows and rolls closely against the edge of the roller 7, and performs neat trimming and shaping work in the direction of the roller 7, ensuring that the edge of the pavement after trimming is more neat. When there is no need to trim the road edge, the construction personnel use the control handle 3 and the lifting device to raise the slider 10, so that the cutting wheel 8 and the rolling roller 7 are in a coaxial state. At this time, the edge of the cutting wheel 8 does not contact the road surface, thereby switching to the normal rolling mode.

[0023] The inner wall of the end of the roller 7 away from the frame beam 1 is circumferentially provided with a chamfer 12, and the inner side of the cutting wheel 8 is provided with a conical surface 13 adapted to the chamfer 12; the lifting shaft 9 passes through the slider 10 through an axial hole, and a spring 14 is provided between the free end of the lifting shaft 9 and the slider 10.

[0024] In this arrangement, when the edge of the pavement is trimmed, the cutting wheel 8 with the conical surface 13 structure can form an inclined end face structure on the edge of the pavement after the trimming. On the one hand, it can avoid the damage caused by the friction between the edge of the pavement and the inner side of the cutting wheel 8 after the cutting wheel 8 is rolled over, which may cause the pavement paving seed material to be lifted up. On the other hand, the trimmed inclined end face increases the stable supporting force and avoids defects caused by collapse of the pavement edge.

[0025] The inner frame plate 4 is provided with a vibration generator, and the vibration generator is connected to the engine 5 through a second transmission system. The vibration generator improves the working efficiency of the road roller 7 and can make the road surface more compacted.

[0026] The output shaft of the engine 5 is provided with a transfer gearbox 15, and the transfer gearbox 15 is provided with a first clutch 16 and a second clutch 17; the first transmission system includes a ring gear 18 arranged in the roller 7, and a first drive gear 19 connected to the first clutch 16, and also includes an intermediate gear 20 meshed between the first drive gear 19 and the ring gear 18; the second transmission system includes a second drive gear 21 connected to the second clutch 17, and a driven gear 22 meshed with the second drive gear 21, and the vibration generator is an eccentric counterweight 23 connected to the driven gear 22; the engine 5, the transfer gearbox 15, the first clutch 16 and the second clutch 17 are respectively connected to the control handle through control cables.

[0027] In this setting, the construction personnel control each pull wire through the operating lever on the control handle 3, thereby realizing the forward and backward movement of the roller 7 and the operation and shutdown of the vibration generator. The working principle of this design is similar to that of the existing hand-held single-wheel gasoline roller. The difference is that the engine 5 is set inside the roller 7, the purpose of which is to increase the roller 7 while reducing the overall size of the equipment. In this design, the air filter, muffler and radiator tank of the engine 5 are arranged on the frame beam 1, and a vent for internal ventilation is provided between the inner frame plate 4 and the frame beam 1.

[0028] The roller roller 7 is provided with a circular groove in the circumferential direction on the surface of the chamfer 12 , and a nylon ring 24 is embedded in the circular groove. The outer surface of the nylon ring 24 protrudes from the surface of the chamfer 12 and abuts against the conical surface 13 of the cutting wheel 8 .

[0029] The nylon ring 24 in this arrangement can effectively reduce the friction and noise between the cutting wheel 8 and the roller 7 during the cutting and trimming process, and the easily replaceable nylon ring 24 can also extend the life of the roller 7 and avoid premature wear of the chamfer 12 thereof.

[0030] The lifting device includes a hydraulic pump 25 connected to the transfer gearbox 15, and a hydraulic cylinder 26 arranged between the slider 10 and the top of the longitudinal slide 6. A control valve is provided on the control handle 3, and the control valve is connected to the hydraulic cylinder 26 and the hydraulic pump 25 respectively through hydraulic pipes.

[0031] In this arrangement, construction personnel control the lifting and lowering of the hydraulic cylinder 26 by controlling the control valve on the handle 3, thereby changing the height of the slider 10 in the longitudinal slide 6 to achieve the setting of the cutting and trimming thickness of the cutting wheel 8. In addition, through the stability of the hydraulic cylinder 26, the kinetic energy of the vibration generator can be effectively transmitted to the cutting wheel 8 through the hydraulic cylinder 26, the slider 10, and the lifting shaft 9, thereby improving the cutting and trimming effect.

[0032] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
