Technical Field
[0001] The utility model relates to the field of seam cutting machines, in particular to a seam cutting machine for road construction. Background Art
[0002] A road construction seam cutter, also often called a concrete pavement seam cutter or road cutter, is a mechanical device that cuts material using a high-speed rotating blade. In concrete pavement construction, seam cutters are primarily used to cut and split the seams of rolled concrete to ensure pavement strength and extend its service life. A seam cutter primarily consists of a base, a drive source, a cutting disc, and a handle. When the drive source is activated, the cutting disc rotates, driving the entire machine, allowing the cutting disc to be used to cut the seams in the concrete pavement.
[0003] When using existing slotting machines, after the drive source is activated, the cutting blade rotates at high speed. A worker pushes the slotting machine and uses the high-speed rotation of the cutting blade to cut the concrete slots. However, in these slotting machines, the cutting blade cannot be cooled during high-speed cutting, which can easily lead to overheating, causing significant wear and tear. In severe cases, it can also easily cause the cutting blade to break, increasing the cost of slotting and providing limited effectiveness. Summary of the Invention

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0018] like Figure 1-Figure 4As shown, a seam cutting machine for road construction includes a base 1, an engine 2 is provided on the base 1, and a cutting blade 3 is provided on the base 1, a protective cover 4 is provided on the base 1, a blowing structure 5 is provided on the base 1, and the end of the blowing structure 5 is connected to the protective cover 4, a wheel 9 is provided at one end of the base 1, and a universal wheel 10 is installed at the other end of the base 1, a control box 6 is provided on the base 1, and an adjustment part 8 is provided on the control box 6, and a handle 7 is installed on the control box 6, the engine 2 and the cutting blade 3 are connected through a transmission assembly 11, and the transmission assembly 11 includes a driving wheel, a driven wheel and a belt, the driving wheel is arranged on the engine 2, the driven wheel is arranged on the rotating shaft of the cutting blade 3, and the belt is sleeved on the driven wheel and the driving wheel.
[0019] When using a seam cutter to cut the seam of a road, the seam cutter is placed on the road surface. After starting the engine 2, the engine 2 drives the driving wheel to rotate. Since a belt is provided on the driving wheel and the driven wheel, the driving wheel drives the driven wheel to rotate through the belt, thereby driving the cutting blade 3 to rotate at high speed. When the cutting blade 3 contacts the road surface, the cutting blade 3 cuts the road surface, thereby achieving the purpose of cutting. During this process, the staff pushes the seam cutter to move through the handle 7 on the control box 6. Under the action of the wheel 9 and the universal wheel 10 on the base 1, the seam cutter moves. During this process, the blowing structure 5 generates gas, and the gas acts on the cutting blade 3, which can cool the cutting blade 3 and prevent the cutting blade 3 from being too hot and causing large wear, thereby ensuring the use effect of the cutting blade 3, and avoiding the breakage of the cutting blade 3 caused by high-temperature cutting, avoiding frequent replacement of the cutting blade 3, and reducing the use cost to a certain extent.
[0020] According to the above embodiment, the blowing structure 5 includes a collection box 501, a fan 503, a hose 505, a mounting hard pipe 506 and a plastic nozzle 507. The fan 503 is set on the collection box 501, the hose 505 is connected to the mounting hard pipe 506, and the hose 505 is connected to the collection box 501. The plastic nozzle 507 is installed at the end of the mounting hard pipe 506. The blowing structure 5 also includes an air inlet 502, a top cover 504, a mounting seat 508, a mounting groove 509 and a tightening bolt 51 0, the air inlet 502 is opened on the collection box 501, the fan 503 is installed at the position of the air inlet 502 on the collection box 501, the top cover 504 is fixed to the upper end of the collection box 501 by screws, the mounting groove 509 is opened on the mounting seat 508, and the mounting seat 508 is fixed on the protective cover 4, the mounting tube 506 is located in the mounting groove 509 on the mounting seat 508, the tightening bolt 510 is threadedly connected to the mounting seat 508, and the end of the tightening bolt 510 is abutted against the mounting tube 50 6, through the provided blowing structure 5, during the slitting process, the fan 503 on the collection box 501 runs to transport air to the hose 505, and finally ejects it from the end of the plastic nozzle 507 at the end of the installation hard pipe 506. The ejected gas acts on the cutting blade 3, which can cool the cutting blade 3 and prevent the cutting blade 3 from being overheated, reducing the wear on the cutting blade 3, thereby reducing the cost of the slitting operation. The installation hard pipe 506 is set in the installation groove 509 on the mounting seat 508 and is fixed with a tightening bolt 510. The height of the installation hard pipe 506 can be quickly adjusted, and it has high flexibility and adaptability. The plastic nozzle 507 can be bent and adjusted, and the current state can be guaranteed to remain unchanged after adjustment, which is convenient for adjusting the end nozzle when needed. It has high flexibility and adaptability. The top cover 504 is easy to disassemble, which is convenient for the staff to perform maintenance and other operations on the fan 503 inside the collection box 501. It has a simple structure and is easy to operate.
[0021] When the air blowing structure 5 is used, after the fan 503 is started, the external air enters the collection box 501 through the air inlet 502 under the action of the fan 503, and then under the continuous action of the fan 503, the air enters the hose 505, and is finally ejected from the end of the plastic nozzle 507 installed at the end of the hard tube 506. The ejected air acts on the cutting blade 3, and has the effect of cooling the cutting blade 3. In this process, the angle of the end of the plastic nozzle 507 can be adjusted. When the adjustment of the plastic nozzle 507 is subject to height restrictions, the hard tube 506 can also be adjusted. The tool is used to loosen the fastening bolt 510 on the mounting seat 508, so that the mounting hard tube 506 moves in the mounting groove 509, thereby lifting and lowering the plastic nozzle 507. After the adjustment is completed, the fastening bolt 510 is rotated with the tool so that the end of the fastening bolt 510 abuts against the mounting hard tube 506. The mounting hard tube 506 is fixed and can continue to be used. When necessary, the fan 503 can also be disassembled and replaced. During operation, after removing the top cover 504 at the upper end of the collection box 501, two fans 503 are removed at a time, and then related operations can be performed. The structure is simple and easy and quick to use.
