Technical Field

[0001] The utility model relates to the field of road surface cutting, in particular to a road surface cutting device. Background Art

[0002] Pavement cutting is a construction technology mainly used in the maintenance, renovation or new construction of roads, bridges and cement concrete buildings. This technology uses professional cutting machinery, such as pavement cutters, to make precise cuts on the road surface in order to groove, repair damaged sections or prepare for the laying of new materials.

[0003] At present, people usually use road cutting machines to cut the road surface. When using the existing road cutting machines, firstly, the cutting machine needs to be started so that the cutting blade contacts the road surface. Due to the different cutting depths, when cutting, people need to press the road cutting machine down to drive the cutting blade to press down to adjust the depth. However, it is relatively laborious to manually press down the road cutting machine.

[0004] In summary, there is an urgent need for a road cutting device that can automatically adjust the cutting depth to solve the above problems. Utility Model Content

A servo motor is installed on the rear bracket. The output shaft of the servo motor is rotatably connected to the bracket on the front side. The output shaft of the servo motor is connected to the connecting frame. The cutter is rotatably arranged on the connecting frame. Vacuum cleaners are installed on the lower parts of the two brackets. The dust suction port of the vacuum cleaner is U-shaped. A collection frame is slidably arranged on the vacuum cleaner. A push rod is connected between the left sides of the two brackets.

[0008] Preferably, guide rails, limit rods and fixing nuts are also included. The two brackets are connected to the guide rails. A limit rod is placed between the two guide rails, and the limit rod passes through the connecting frame. A fixing nut is threadedly arranged on the front of the limit rod.

[0009] Preferably, a transparent plate is also included, and two transparent plates are connected to the two collecting frames on the sides away from each other.

[0010] Preferably, the guide rail is arranged in an arc shape.

[0011] Preferably, U-shaped grooves are formed on both the upper and lower sides of the handle of the collection box.

[0012] Preferably, the push rod is arranged in a shape of "7".

[0013] The beneficial effects of the utility model are as follows:

[0014] 1. By using the servo motor as the driving force, the utility model can drive the connecting frame and the cutter to rotate, so as to achieve the purpose of depth adjustment by adjusting the angle of the cutter and realize automatic adjustment.

[0015] 2. The utility model can further fix the connecting frame and the cutter through the limiting rod and the fixing nut. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following further describes the utility model with reference to the drawings and embodiments.

[0022] Embodiment: A road cutting device, refer to Figures 1 - 4As shown in the figure, it includes a bracket 1, universal wheels 2, a servo motor 3, a connecting frame 4, a cutter 5, a guide rail 6, a limiting rod 7, a fixing nut 8, a vacuum cleaner 9, a collection box 10, a transparent plate 11 and a push rod 12. There are two brackets 1, which are symmetrically arranged front and back. Universal wheels 2 are rotatably arranged on both the left and right sides of the lower part of the bracket 1. The servo motor 3 is installed on the rear bracket 1, and the output shaft of the servo motor 3 is rotatably connected to the front bracket 1 through a coupling. A connecting frame 4 is welded on the output shaft of the servo motor 3, and a cutter 5 is rotatably arranged on the connecting frame 4. The servo motor 3 can drive the cutter 5 to rotate to achieve the purpose of automatically adjusting the cutting depth. Guide rails 6 are welded on both brackets 1. The guide rails 6 are arc-shaped. A limiting rod 7 is placed between the two guide rails 6, and the limiting rod 7 passes through the connecting frame 4. A fixing nut 8 is threadedly arranged at the front of the limiting rod 7. The fixing nut 8 and the limiting rod 7 can further fix the connecting frame 4. Vacuum cleaners 9 are installed on the lower part of both brackets 1. The dust suction port of the vacuum cleaner 9 is U-shaped. The vacuum cleaner 9 is used to adsorb dust and reduce the inhalation of dust by people. A collection box 10 is slidably arranged on the vacuum cleaner 9. U-shaped grooves are opened on both the upper and lower sides of the handle of the collection box 10. Two transparent plates 11 are connected to the mutually remote sides of the two collection boxes 10. A push rod 12 is welded between the left sides of the two brackets 1. The push rod 12 is in a 7-shaped configuration.

[0023] When the device needs to be used, people first hold the push rod 12 tightly and push the device to the designated position through the universal wheels 2. Then, turn the fixing nut 8 so that the fixing nut 8 moves forward to loosen the guide rail 6. The guide rail 6 no longer fixes the connecting frame 4 and the cutter 5. Then, start the cutter 5, and the cutter 5 rotates to cut the road surface. While cutting, the servo motor 3 can be started. The rotation of the output shaft of the servo motor 3 drives the connecting frame 4 to rotate leftward, and the leftward rotation of the connecting frame 4 drives the cutter 5 to rotate leftward, so as to achieve the purpose of depth adjustment by adjusting the angle of the cutter 5. After adjusting to the appropriate depth, turn off the servo motor 3, and then reverse the fixing nut 8 so that the fixing nut 8 moves backward to fix the guide rail 6 again, thereby being able to better fix the connecting frame 4 and the cutter 5. At this time, people can continue to push the device to drive the cutter 5 to move and cut the road surface. While cutting the road surface, the vacuum cleaner 9 can be started, so that the dust generated during cutting can be sucked into the collection box 10, reducing the inhalation by people. The amount of dust collected in the collection box 10 can be observed through the transparent plate 11. After cutting is completed, turn off the cutter 5 and the vacuum cleaner 9, and finally take out the collection box 10 to process the dust.

[0024] The above embodiments are only the preferred embodiments of the present invention and are not used to limit the scope of implementation of the present invention. Therefore, all equivalent changes made according to the content described in the claims of the present invention should be included within the scope of the claims of the present invention.
