Description

Technical Field

[0001] The present invention relates to the technical field of slitting devices, in particular to a slitting device for municipal concrete road construction. Background Art

[0002] Concrete is often used in the construction of municipal roads. During the process of concrete solidification and hardening, cement hydration releases a large amount of heat, causing the concrete temperature to rise; after most of the cement hydration reactions are completed, the concrete temperature begins to drop. During the cooling process, the concrete has already solidified and hardened. The shrinkage caused by the cooling will cause the concrete to crack, and the direction of the cracks is relatively random, seriously affecting the quality and service life of the road surface. Therefore, it is necessary to set shrinkage joints on the concrete slabs. The existing technology generally uses a slitting device for cutting. A road slitting machine is a device used to cut road gaps. Its working principle is to complete the slitting operation through an electric-driven fine steel saw blade. It has the characteristics of simple structure, small size, easy to move, and easy to start. It plays a major role in road construction.

[0003] Existing slitting machines can overheat their blades during extended operation, shortening their service life. To cool the blades and prevent dust from being generated during cutting, water tanks and spray pipes are typically installed inside the slitting machines to spray water on the blades and the road surface. However, spraying water while cutting wastes a significant amount of water. Furthermore, when slitting on hard surfaces or encountering obstacles such as hard rocks, the forced cutting can easily damage the blades, impacting subsequent cutting operations. Therefore, a slitting device for municipal concrete road construction that conserves water and protects the blades is urgently needed. Summary of the Invention

[0023] During use, by providing a dust removal and cooling mechanism, dust absorbed by the dust hood under the action of the vacuum cleaner 16 enters the bag 17 through the air inlet pipe 24. Due to the obstruction of the filter 18, large pieces of debris sucked in by the vacuum cleaner 16 remain in the bag 17. Small particles of dust and other debris are filtered by the filter 18 in the bag 17 and then passed into the water below the cover 19 to be absorbed. The sewage in the water tank 2 can also be sprayed onto the cutting blade 5 through the outlet pipe 23 to cool the cutting blade 5, preventing the cutting blade 5 from overheating and affecting its service life, thereby improving the durability of the equipment and making full use of water resources to avoid water waste. When the debris and other debris accumulated in the bag 17 reaches a certain level, the filter 18 at the bottom of the bag 17 can be removed and removed to facilitate cleaning of the debris in the bag 17.

[0024] In this embodiment, the cutting mechanism includes a box body 3, a buffer device is provided in the box body, and the buffer device is connected to the blade. The buffer device includes an arch support frame, a first connecting rod, a second connecting rod, a cylinder, a second slider, a stopper, and a second spring. Specifically, the box body 3 is fixedly installed in the middle of the bottom of the mobile frame 1, a fixed block 9 is fixedly installed on the top of the box body 3, a stopper 11 is slidably installed in the box body 3 at a position directly below the fixed block 9, and a second spring 10 is fixedly connected between the top of the stopper 11 and the fixed block 9. The box body 3 has two outlets at the bottom, each of which is provided with a cylinder 13 above the outlet. Both cylinders 13 are fixedly installed in the box body 3, and a second slider 14 is slidably installed in each cylinder 13. The upper surface of each second slider 14 is hinged to a first connecting rod 12, and the top of each first connecting rod 12 is fixedly connected to the stopper 11. The bottom of each second slider 14 is fixedly connected to a second connecting rod 15, and the bottom of each second connecting rod 15 is fixedly connected to the arch support frame. The cutting blade 5 is located below the arch support frame.

[0025] The cutting mechanism includes a cutting blade 5, a blade cover 6, and a protective cover 4. A cutting blade 5 is rotatably mounted in each blade cover 6. A temperature sensor is provided on the surface of each cutting blade 5. A protective cover 4 is slidably mounted on the lower end of each blade cover 6. Two first sliders 7 are provided on the top of each protective cover 4. Two slide grooves are provided in each blade cover 6 to match the first sliders 7. A first spring 8 is installed in each slide groove. The two ends of each first spring 8 are respectively connected to the first slider 7 and the blade cover 6. The dust cover and the nozzle are both installed in the blade cover 6 and face the cutting blade 5.

[0026] A rotating drum is mounted in the center of each cutting blade 5. A motor drives the drum, causing the cutting blade 5 to rotate and cut the road surface. A fixed shaft is threaded through the drum, which is rotatably mounted on the shaft's surface. The drum rotates on the shaft while the shaft remains stationary. Arched support frames are located above the left and right ends of the shaft, extending beyond the blades. Blade covers 6, a two-piece structure, are removably mounted on either side of the arched support frames.

[0027] When in use, a rotating cylinder is installed in the middle of the cutting blade 5, and the rotating cylinder is driven to rotate by the motor, so that the cutting blade 5 rotates to cut the road surface. When the cutting blade 5 encounters a harder road surface or an obstacle such as a stone, the arched support frame fixedly connected to the cutting blade 5 moves upward, and the arched support frame drives the second slider 14 to move upward in the cylinder 13 through the second connecting rod 15. The second slider 14 drives the stopper 11 to move upward in the box body 3 through the first connecting rod 12, compressing the second spring 10, so that the cutting blade 5 can flexibly retract when encountering a hard obstacle to prevent the blade from being damaged. When the cutting blade 5 passes over the obstacle, the second spring 10 restores its deformation, thereby driving the cutting blade 5 to move downward for reset;

[0028] The cutting blade 5 is located inside the blade cover 6. The protective cover 4 is provided so that the blade cover 6 can slide up and down. Under the action of the first spring 8, the protective cover 4 is always kept in the extended state and completely covers the cutting blade 5, preventing dust particles and debris generated during the cutting process from being ejected onto people, thereby ensuring the personal safety of workers.

[0029] A microcontroller and a battery are provided in the box 3. The microcontroller is electrically connected to the motor, temperature sensor and solenoid valve through wires, and the battery provides power to the electrical components in the device.

[0030] From the above description, it can be seen that the above-mentioned embodiment of the present invention achieves the following technical effects: by arranging a buffer device in the box body, the buffer device is connected to the blade, and when encountering a harder road surface or obstacles such as stones, it can be extended and retracted upward to drive the cutting blade 5 to move upward, thereby preventing the cutting blade 5 from breaking; by arranging a protective cover 4 and a blade cover 6 at the cutting blade 5, it can effectively prevent dust particles and debris generated by cutting from being ejected onto people, thereby ensuring the personal safety of the staff; by arranging a temperature sensor on the cutting blade 5, when it is detected that the temperature is too high, the microcontroller controls the solenoid valve of the nozzle of the water outlet pipe 23 to automatically open to spray water to cool the cutting blade 5, and the dust generated by the cutting blade 5 during operation is filtered by the filter 18 of the bag 17 through the vacuum cleaner 16 and the dust cover, and then passed into the water inside the water tank 2 to absorb the dust. The sewage in the water tank 2 can also be sprayed onto the cutting blade 5 through the water outlet pipe 23 to cool the cutting blade 5, thereby preventing the cutting blade 5 from overheating and affecting its service life, thereby improving the durability of the equipment, and at the same time making full use of water resources and avoiding waste of water resources.
