Description

Technical Field

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

[0002] A road cutting machine is a tool used in road maintenance and construction. Its main function is to cut grooves in the road surface, and it is commonly used on cement and asphalt roads.

[0003] The patent publication number "CN221118198U" discloses a "road cutting machine," which includes a base. A fixed frame is fixedly connected to the surface of the base. A sliding frame is movably connected to the top of the fixed frame. A movable seat is movably connected to the top of the sliding frame. A notch is opened at the bottom of the movable seat, and a cutting blade is movably connected within the notch. A cutting motor is fixedly connected to one side of the movable seat, and one end of the output shaft of the cutting motor is fixed to the cutting blade. An electric telescopic rod is fixedly connected to the top of the fixed frame, and one end of the electric telescopic rod passes through the fixed frame and is fixed to the sliding frame. This machine not only allows the movable seat to move to one side along the top of the fixed frame by rotating a screw, changing the lateral position of the cutting blade and reducing manual operation, saving time and effort, and making adjustments more convenient, but also allows the dust generated during cutting to be absorbed by a vacuum cleaner and collected into a collection cylinder through a suction pipe, reducing dust pollution during the cutting process.

[0004] To address the aforementioned issues, the cutting wheel is used to cut the road surface. This wheel generates significant vibrations during the cutting process. When these vibrations are transmitted to the entire frame, they cause the frame to move, resulting in the cutting wheel shifting its position due to the frame's vibrations and creating uneven cuts.

[0005] Therefore, this utility model provides a road surface cutting machine to solve the above problems. Utility Model Content

[0031] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] Reference Figures 1 to 5 This application provides a road cutting machine, including a frame 1. A moving component 3 is provided on the top of the frame 1, and a cutting component 2 is provided at the bottom of the moving component 3. A dust removal component 4 is provided on the top of the frame 1. The cutting component 2 includes a moving block 21 and a protective shell 23. A cutting wheel 24 is rotatably connected inside the protective shell 23. Two connecting frames 26 are fixedly installed on the outside of the protective shell 23. The moving block 21 is located above the protective shell 23. Two shock absorbers 27 are hinged between the top of the connecting frame 26 and the bottom of the moving block 21. A mating groove 22 is provided inside the frame 1. The protective shell 23 and the cutting wheel 24 are both located inside the mating groove 22. A handle 6 is fixedly installed on the top of the frame 1, and wheels 5 are fixedly installed at the four corners of the bottom of the frame 1.

[0033] A cutting motor 25 is fixedly mounted on the side of the protective shell 23. The output end of the cutting motor 25 moves through the inside of the protective shell 23 and is fixedly connected to the center of the cutting wheel 24.

[0034] The moving component 3 includes a frame 31, which is fixedly mounted on the top of the frame 1 and located above the mating groove 22. Two screws 32 are rotatably connected between the frame 31 and the frame 1. A lifting plate 33 is screwed between the outer sides of the two screws 32. The lifting plate 33 is slidably connected between the two side walls of the frame 31. A moving block 21 is fixedly mounted on the bottom of the lifting plate 33. Two rotating rods 35 are rotatably connected to the top of the frame 31. The bottom of the rotating rods 35 moves through the interior of the frame 31 and is fixedly connected to the screws 32. A belt drive system 34 is provided between the tops of the two rotating rods 35. The belt drive system 34 consists of two pulleys and a belt wound around the outside of the pulleys. The two pulleys are fixedly mounted on the tops of the corresponding rotating rods 35. A bracket 36 is fixedly mounted on the top of the frame 31. A lifting motor 37 is fixedly mounted on the top of the bracket 36. The output end of the lifting motor 37 moves through the interior of the bracket 36 and is fixedly connected to the left side belt drive system 34.

[0035] In this embodiment, during cutting, the lifting motor 37 is activated to drive the pulley to rotate. The rotation of the pulley, via a belt, synchronously drives two screws 32 to rotate. The synchronous rotation of the screws 32 drives the lifting plate 33 to move up and down. The up and down movement of the lifting plate 33 drives the moving block 21 to move up and down. The up and down movement of the moving block 21 changes the up and down position slot of the cutting wheel 24, thereby adjusting the cutting depth. During cutting, the cutting motor 25 drives the cutting wheel 24 to rotate, cutting the road surface. During cutting, the handle 6 and the wheels 5 move the frame 1 to cut the road surface. The shock absorber 27 absorbs and buffers the vibration generated during cutting, thus achieving a stable movement of the frame 1 during cutting and ensuring the cutting effect.

[0036] Reference Figures 1 to 5 In one aspect of this embodiment, the dust removal assembly 4 includes a three-way valve 45, with arc-shaped tubes 46 fixedly installed on both the left and right sides of the three-way valve 45. The arc-shaped tubes 46 are located above the outer side of the protective shell 23, and a nozzle 47 is fixedly installed at the bottom of the arc-shaped tubes 46. The nozzle 47 is inserted into the inside of the protective shell 23, and the outlet of the nozzle 47 is located outside the cutting wheel 24 inside the protective shell 23.

[0037] A water tank 41 and a water pump 42 are fixedly installed on the top of the frame 1. A first connecting pipe 43 is fixedly installed between the water inlet of the water pump 42 and the water tank 41, and a second connecting pipe 44 is fixedly installed between the water outlet of the water pump 42 and the three-way valve 45.

[0038] In this embodiment, during cutting, the water pump 42 is started and the water inside the water tank 41 is introduced into the three-way valve 45 through the first connecting pipe 43 and the second connecting pipe 44. Then, the water is introduced into the nozzle 47 through the arc-shaped pipe 46. The water is sprayed out to the outside of the cutting wheel 24 through the nozzle 47. By spraying the cutting wheel 24, the heat generated during cutting can be quickly dissipated, and the dust generated during cutting can be reduced.

[0039] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0040] Working principle: During cutting, the lifting motor 37 is activated, driving the pulley to rotate. The rotation of the pulley, via a belt, synchronously drives two screws 32 to rotate. The synchronous rotation of the screws 32 drives the lifting plate 33 to move up and down. The up and down movement of the lifting plate 33 drives the moving block 21 to move up and down. The up and down movement of the moving block 21 changes the up and down position groove of the cutting wheel 24, thereby adjusting the cutting depth. During cutting, the cutting motor 25 drives the cutting wheel 24 to rotate, cutting the road surface. During cutting, the handle 6 and the wheels 5 move the frame 1. The vehicle moves to cut the road surface, and the shock absorber 27 absorbs and buffers the vibration generated during cutting, thereby achieving a stable movement of the frame 1 during cutting and ensuring the cutting effect. During cutting, the water pump 42 is started and the water in the water tank 41 is introduced into the three-way valve 45 through the first connecting pipe 43 and the second connecting pipe 44, and then into the nozzle 47 through the arc pipe 46. The water is sprayed out to the outside of the cutting wheel 24 through the nozzle 47. Spraying the cutting wheel 24 can quickly dissipate the heat generated during cutting and reduce the dust generated during cutting.
