Description

Technical Field

[0001] This utility model specifically relates to a cutting machine for road construction, belonging to the field of road construction technology. Background Technology

[0002] A road cutting machine is a widely used cutting device for cutting road expansion joints or repairing asphalt. With the continuous construction of roads, the demand for road cutting machines is also increasing. Currently, after road cutting machines complete the cutting operation, a large amount of gravel, dust, and road debris remains inside the cut joint. If not cleaned, this will affect the adhesion of the subsequent joint filler material, leading to problems such as cracking and peeling after filling. In existing technologies, cleaning the cut joint requires manual high-pressure water guns or brooms for secondary operations, which not only increases labor costs but also has low cleaning efficiency, causing a disconnect between the cutting and cleaning processes and significantly reducing overall construction efficiency.

[0015] Please see Figure 1-6 As shown, a road construction cutting machine includes: a frame 1, a cutting disc 2 on one side of the frame 1, a protective cover 3 installed on the upper end of the frame 1 and covering the upper end of the cutting disc 2, two movable wheels 4 fixedly connected to the front and rear sides of the frame 1, a cleaning component 5 on the front side of the frame 1, and an adjustment component 6 on the upper end of the frame 1. The cleaning assembly 5 includes an adjusting shell 501. A worm gear 502 is rotatably connected to the inner wall of the adjusting shell 501. A rotating shaft 503 is rotatably connected to the inner wall of the adjusting shell 501. A worm wheel 504 is fixedly connected to the outer wall of the rotating shaft 503. An adjusting rod 505 is fixedly connected to the outer wall of one end of the rotating shaft 503. A spray shell 506 is fixedly connected to one side of the adjusting rod 505. A high-pressure nozzle 507 is fixedly connected to the outer wall of the spray shell 506. A connecting rod 508 is rotatably connected to the front side wall of the spray shell 506 via a connecting shaft. Nuts are threadedly connected to the outer walls of both connecting rods 508. Threaded grooves for the nuts are provided on the outer walls of both connecting rods 508. An auxiliary wheel 509 is rotatably connected to one side of each connecting rod 508. The worm gear 502 is driven to rotate by a knob 5012, which in turn drives the worm wheel 504 and the adjusting rod 505 to rotate, allowing the high-pressure nozzle 507 to be aligned with the cutting seam for cleaning.

[0016] The adjustment assembly 6 includes an adjustment frame 601 fixedly connected to the upper end of the frame 1. An electric push rod 602 is installed on the inner wall of the adjustment frame 601, and a through hole adapted to the electric push rod 602 is provided at the upper end of the frame 1. A connecting plate 603 is fixedly connected to the output end of the electric push rod 602, passing through the frame 1. Rollers 604 are rotatably connected to both sides of the connecting plate 603. Two guide rods 605 are fixedly connected to the upper end of the connecting plate 603, both of which pass through the frame 1 and are slidably connected thereto. The electric push rod 602 drives the connecting plate 603 to rise and fall, causing the rollers 604 to contact the ground and lift the front end of the frame 1, thereby adjusting the cutting depth of the cutting disc 2.

[0017] A water tank 7 is fixedly connected to the upper end of the frame 1. A pump body 8 is installed on one side of the water tank 7. A water supply pipe 9 is fixedly connected to the output end of the pump body 8. A nozzle is fixedly connected to one end of the water supply pipe 9 through the protective cover 2, and the nozzle is located on one side of the cutting disc 3. Water is drawn from the water tank 7 by the pump body 8 and sprayed out from the nozzle through the water supply pipe 9 to cool the cutting disc 2.

[0018] A pressure pump 10 is fixedly connected to one side of the water tank 7. A pressure pipe 11 is fixedly connected to the output end of the pressure pump 10. The end of the pressure pipe 11 away from the pressure pump 10 is connected to the spray housing 506. The pressure pump 10 outputs high-pressure water to the spray housing 506 through the pressure pipe 11, which is then sprayed out through the high-pressure nozzle 507 to flush away the residual gravel and dust inside the cutting seam.

[0019] A drive motor 12 is fixedly connected to the upper end of the frame 1. A drive wheel 13 is fixedly connected to the output end of the drive motor 12. A driven wheel is rotatably connected to one side of the frame 1, and the driven wheel is fixedly connected to the cutting disc 2 through a connecting shaft. The drive wheel 13 is connected to the driven wheel via a belt. The drive motor 12 outputs the rotation of the drive wheel 13, which drives the driven wheel to rotate through the belt, thereby causing the cutting disc 2 to rotate.

[0020] A rotating rod 5011 is rotatably connected to the upper end of the adjusting housing 501. A knob 5012 is fixedly connected to the upper end of the rotating rod 5011. The rotating rod 5011 passes through one end of the knob 5012 and is fixedly connected to the worm gear 502. The knob 5012 drives the rotating rod 5011 and the worm gear 502 to rotate.

[0021] The worm gear 504 is located on one side of the worm 502, and the worm 502 is connected to the worm gear 504 in a transmission connection. The rotation of the worm 502 drives the worm gear 504 to rotate, which in turn drives the rotating shaft 503 to rotate.

[0022] The implementation principle of a road construction cutting machine according to an embodiment of this application is as follows: Before operation, the electric push rod 602 is started to push the connecting plate 603 to slide down along the guide rod 605, causing the roller 604 to contact the ground and lift the front end of the frame 1, so that the contact depth between the cutting disc 2 and the ground changes. During cutting, the drive motor 12 is started to drive the drive wheel 13 to rotate, and drives the driven wheel to rotate synchronously through the belt drive. The driven wheel drives the cutting disc 2 to rotate at high speed through the connecting shaft to complete the road cutting operation. At this time, the protective cover 3 covers the upper end of the cutting disc to block the flying of stone fragments generated during cutting. At the same time, the pump body 8 is started to draw water from the water tank 7 during the cutting process, and delivers it to the nozzle inside the protective cover through the water pipe 9. The nozzle sprays the cutting disc 2, thereby absorbing the heat generated by cutting and preventing the cutting disc from being worn or cracked due to high temperature. When cleaning the cut seam, turning the knob 5012 drives the rotating rod 5011 and the worm gear 502 to rotate. The worm gear meshes with the worm wheel 504, driving the rotating shaft 503 and the adjusting rod 505 to rotate. This brings the spray shell 506 at one end of the adjusting rod 505 closer to the cut seam. The pressurizing pump 10 is started, drawing water from the water tank 7 and pressurizing it. The water is then delivered to the spray shell 506 through the pressurizing pipe 11. The high-pressure water flows through the high-pressure nozzle 507 and sprays out at high speed, penetrating deep into the cut seam to clean the dust and debris inside. At the same time, the auxiliary wheel 509 at the end of the connecting rod 508 contacts the ground to prevent the spray shell 506 from shaking under impact, ensuring that the nozzle maintains the optimal distance from the cut seam and guaranteeing the stability of the spray shell 506 during the cleaning process.

[0023] The pump body 8, the booster pump 10, and the drive motor 12 in this device are electrically connected to an external power source and a controller, which is a conventional known device used for control.
