Description

Technical Field

[0001] This utility model relates to the field of slit cutting machine technology, specifically a slit cutting machine with an adjustment component. Background Technology

[0002] Although a concrete cutting machine is a small and simple tool, it plays a vital role in cement pavement construction. Cutting joints is an essential step in the construction process, directly affecting the pavement's strength and lifespan. Its working principle involves using a power-driven diamond saw blade to perform the cutting operation.

[0003] Currently, small concrete cutting machines used for cutting joints in riverbanks, ditches, and slopes of sand and gravel concrete surfaces all employ a screw and nut structure to adjust the cutting depth. The saw blade is raised and lowered by manually rotating the screw. This method has two drawbacks: firstly, manually rotating the screw is slow, time-consuming, and labor-intensive; secondly, the screw and nut require lubrication, which not only attracts dust but also dries out over time, causing the screw and nut to jam, thus preventing the concrete cutting machine from operating normally and becoming a major problem in projects such as roads, squares, rivers, ditches, and production workshops. A new type of concrete cutting machine is characterized by: firstly, the use of an electric lifting mechanism, replacing the original screw and nut structure. During operation, simply jogging the lifting switch completes the raising and lowering of the cutting blade, solving the problems of manual lifting, time-consuming, labor-intensive operation, and jamming inherent in traditional concrete cutting machines.

[0004] Therefore, we propose a slitting machine with an adjustment component. Summary of the Invention

[0005] The purpose of this invention is to provide a slitting machine with an adjustment component to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cutting machine with an adjustment component, comprising a mounting frame, an adjustment component installed above the mounting frame, the adjustment component being used to adjust the overall cutting depth of the device, the adjustment component solving the problem that the original concrete surface cutting machine used manual rotation of the screw for lifting and lowering was time-consuming, labor-intensive, and prone to jamming, and a cutting component installed above the adjustment component, the adjustment component being used to provide power for the cutting of the device.

[0007] Preferably, the adjustment assembly includes a support frame, with two first mounting blocks fixedly connected to the front wall of the mounting frame, a rotating shaft rotatably connected between the two first mounting blocks, the outer surface of the rotating shaft rotatably connected to the rear of the support frame, two second mounting blocks fixedly connected to the upper surface of the support frame, a second rotating rod rotatably connected between the adjacent sides of the two second mounting blocks, a fixed frame fixedly connected to the front of the upper surface of the mounting frame, a first rotating rod rotatably connected between the inner walls of the fixed frame, a fixed block rotatably connected to the outer surface of the first rotating rod, and an electric push rod fixedly mounted on the side of the fixed block near the second mounting blocks, the output shaft of the electric push rod rotatably connected to the outer surface of the second rotating rod.

[0008] Preferably, a spring steel plate is fixedly installed between the bottom surface of the support frame and the rear wall of the mounting frame.

[0009] Preferably, the operation of the electric actuator can be adjusted by a power switch adapted to it.

[0010] Preferably, the length of the mounting bracket can be arbitrarily spliced, and an appropriate number of the adjustment components can be installed on top of the mounting bracket.

[0011] Preferably, the cutting assembly includes a motor mounted on the upper surface of a support frame. A third mounting block is fixedly connected to the left side of the support frame. A round rod is rotatably connected to the side of the third mounting block. A cutting blade is fixedly connected to the end of the round rod away from the third mounting block. A transmission wheel is fixedly connected to both the output shaft of the motor and the outer surface of the round rod. A transmission belt drives between the two transmission wheels.

[0012] Preferably, the number of drive belts is at least two.

[0013] Preferably, the front end of the support frame is at a certain distance from the front wall of the mounting frame.

[0014] This utility model has at least the following beneficial effects:

[0015] 1. When it is necessary to adjust the overall cutting depth of the device, simply jog the power switch connected to the electric push rod. When the output end of the electric push rod extends, the output shaft of the transmission belt will push the second rotating rod. Then, through the connection between the second mounting block and the second rotating rod, the support frame can be pushed downward. At this time, through the cooperation of the first mounting block and the rotating shaft and the rotational connection with the support frame, and through the cooperation between the first rotating rod, which is rotatably connected to the support frame, and the fixed block, the support frame can be flipped downward a portion. Similarly, when the output end of the transmission belt retracts, the support frame can be flipped upward a portion.

[0016] By setting up an adjustment component, the overall cutting depth of the device can be easily adjusted, which solves the problem that it is time-consuming and laborious to manually turn the screw when adjusting the cutting depth, and the screw is prone to rusting and jamming.

[0017] 2. When cutting is required, simply turn on the power switch connected to the motor. This will cause the motor's output shaft to rotate, which in turn drives the transmission wheel, which is fixedly connected to the motor's output shaft, to rotate synchronously. Then, through the cooperation of the third mounting block and the round rod with the cutting blade, the two transmission wheels can be connected by a transmission belt to make the cutting blade rotate and cut. Setting at least two transmission belts can make the rotation of the cutting blade more stable.

[0018] By setting up a cutting assembly, the power for the rotating cutting blade can be provided. By setting both the motor and the third mounting block on the support frame, the height of the cutting blade can be adjusted when the support frame is flipped by the adjustment assembly.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 This utility model provides a technical solution:

[0026] Example 1: A cutting machine with an adjustment component includes a mounting frame 3, an adjustment component 1, which is mounted above the mounting frame 3 and is used to adjust the overall cutting depth of the device. The adjustment component 1 solves the problem that the original concrete surface cutting machine used manual rotation of the screw for lifting and lowering, which was time-consuming, labor-intensive, and prone to jamming. A cutting component 2 is mounted above the adjustment component 1 and is used to provide power for the cutting of the device.

[0027] Adjustment component 1 includes a support frame 4. Two first mounting blocks 5 are fixedly connected to the front wall of the mounting frame 3. A rotating shaft 6 is rotatably connected between the two first mounting blocks 5. The outer surface of the rotating shaft 6 is rotatably connected to the rear of the support frame 4. Two second mounting blocks 11 are fixedly connected to the upper surface of the support frame 4. A second rotating rod 12 is rotatably connected between the sides of the two second mounting blocks 11 that are close to each other. A fixing frame 7 is fixedly connected to the front of the upper surface of the mounting frame 3. A first rotating rod 8 is rotatably connected between the inner walls of the fixing frame 7. A fixing block 10 is rotatably connected to the outer surface of the first rotating rod 8. An electric push rod 9 is fixedly installed on the side of the fixing block 10 that is close to the second mounting block 11. The output shaft of the electric push rod 9 is rotatably connected to the outer surface of the second rotating rod 12.

[0028] A spring steel plate 13 is fixedly installed between the bottom surface of the support frame 4 and the rear wall of the mounting frame 3. This plate can provide some support for the support frame 4 as a whole and will not cause any obstruction to the slight rotation of the support frame 4.

[0029] The operation of the electric linear actuator 9 can be adjusted via a compatible power switch.

[0030] The length of the mounting bracket 3 can be freely spliced, and the adjustment components 1 can be installed in appropriate quantities on top of the mounting bracket 3.

[0031] When it is necessary to adjust the overall cutting depth of the device, simply turn on the power switch that is electrically connected to the electric push rod 9. When the output end of the electric push rod 9 extends, the output shaft of the transmission belt 19 will push the second rotating rod 12. Then, through the connection between the second mounting block 11 and the second rotating rod 12, the support frame 4 can be pushed downward. At this time, through the cooperation of the first mounting block 5 and the rotating shaft 6 and the rotational connection with the support frame 4, and through the cooperation between the first rotating rod 8, which is rotatably connected to the support frame 4, and the fixed block 10, the support frame 4 can be flipped downward by a part. Similarly, when the output end of the transmission belt 19 retracts, the support frame 4 can be flipped upward by a part.

[0032] By setting adjustment component 1, the overall cutting depth of the device can be easily adjusted, which solves the problem that it is time-consuming and laborious to manually turn the screw when adjusting the cutting depth, and the screw is prone to rusting and jamming.

[0033] In embodiment 2, the cutting assembly 2 includes a motor 14, which is mounted on the upper surface of the support frame 4. A third mounting block 15 is fixedly connected to the left side of the support frame 4. A round rod 16 is rotatably connected to the side of the third mounting block 15. A cutting blade 17 is fixedly connected to the end of the round rod 16 away from the third mounting block 15. A transmission wheel 18 is fixedly connected to both the output shaft of the motor 14 and the outer surface of the round rod 16. A transmission belt 19 is connected between the two transmission wheels 18.

[0034] The number of drive belts 19 is at least two, which can make the motor 14 more effective in driving the cutting blade 17.

[0035] The front end of the support frame 4 is a certain distance from the front wall of the mounting frame 3 to avoid the mounting frame 3 obstructing the support frame 4 when it is being flipped.

[0036] When slitting is required, simply turn on the power switch connected to the motor 14. This will cause the output shaft of the motor 14 to rotate, which will drive the transmission wheel 18, which is fixedly connected to the output shaft of the motor 14, to rotate synchronously. Then, through the cooperation of the third mounting block 15 and the round rod 16 with the cutting blade 17, the two transmission wheels 18 can be connected by the transmission belt 19 to make the cutting blade 17 rotate and cut. By setting the number of transmission belts 19 to at least two, the rotation of the cutting blade 17 can be made more stable.

[0037] By setting the cutting component 2, the power for the rotation and cutting of the cutting blade 17 can be provided. By setting the motor 14 and the third mounting block 15 to be mounted on the support frame 4, the height of the cutting blade 17 can be adjusted when the support frame 4 is flipped by the adjusting component 1.

[0038] When seam cutting is required, more than one seam cutting machine can be started at the same time. Multiple seam cutting machines can be used simultaneously in different environments, depending on the judgment of the technicians.
