During the cutting process, the cooling mechanism will spray cooling water to the cutting blade 22 to avoid the heat generated by friction when the cutting blade 22 cuts concrete. The cutting efficiency and effect are affected, and the service life of the cutting blade 22 is affected by excessive temperature.

[0027] The shielding member 31 is semicircular in shape, and a groove 311 is provided on the bottom surface of the shielding member 31, and the groove 311 is semicircular in shape; the shielding member 31 is semicircular in shape to prevent the shielding member 31 from being too large and affecting the cutting depth of the cutting blade 22; the arc surface of the shielding member 31 faces upward; part of the cutting blade 22 is located in the groove 311, and part of it extends from the bottom surface of the shielding member 31; when the cutting depth is not deep, cooling water is sprayed onto the cutting blade 22 through the water outlet 323 when the cutting blade 22 rotates for cutting, and the rotation of the cutting blade 22 will bring the cooling water to the position where the cutting blade 22 contacts the concrete, which is convenient for cooling the cutting blade 22, and the rotation of the cutting blade 22 will cause the cooling water to splash, and at this time, the shielding member 31 can shield the splashing cooling water.

[0028] An arc plate 32 is arranged below the inner top surface of the groove 311, and the arc plate 32 is in contact with the side wall of the groove 311; one end surface of the arc plate 32 is connected to the inner top surface of the groove 311 by a connecting plate 321, so that an arc-shaped chamber is formed between the arc plate 32 and the inner top surface of the groove 311, and the other end of the chamber is open; the length of the arc plate 32 is smaller than the length of the inner top surface of the groove 311, and the arc strip 33 can slide in the arc-shaped chamber, and the arc strip 33 can extend from the opening of the chamber, and then extend from the bottom surface of the shielding member 31, so that the part of the cooling water splashing is increased, and the arc strip 33 extending from the bottom surface of the shielding member 31 can block the splashing of cooling water generated during the rotation and cutting process of the cutting blade 22.

[0031] The arc surface of the shielding member 31 is provided with an arc hole 312, the arc hole 312 is connected to the arc chamber, an arc strip 33 is slidably provided in the arc chamber, a handle 331 is provided on the top surface of the arc strip 33, the handle 331 passes through the arc hole 312 and extends out of the arc surface of the shielding member 31; the arc surface of the shielding member 31 is provided with equidistant blocks 313, and a card slot 314 is provided on the side of the block 313 facing the handle 331 The handle 331 is provided with a protrusion 332 on the side facing the block 313, and the protrusion 332 is connected to the inner wall of the receiving groove on the handle 331 through a first spring; the protrusion 332 is adapted to the groove 314; an accordion plate is provided between the handle 331 and the inner wall of the arc hole 312; the top surface of the arc strip 33 contacts the inner top surface of the groove 311, and the side wall of the arc strip 33 contacts the side wall of the groove 311; A protrusion 333 is provided on the bottom surface of the arc strip 33, and the protrusion 333 is in contact with the top surface of the arc plate 32; a flow channel 334 is opened inside the arc strip 33, and the two ends of the flow channel 334 are located on the two ends of the arc strip 33; a joint 335 is provided at one end of the arc strip 33 close to the connecting plate 321; the arc strip 33 can be driven to rotate by the handle 331, and the handle 331 can facilitate the rotation of the arc strip 33; after the arc strip 33 is rotated to the required position, the protrusion 332 is extended into the corresponding slot 314 to fix the arc strip 33 to prevent the arc strip 33 from moving; the accordion plate can prevent the cooling water in the chamber from flowing out of the strip hole; the joint 335 can be connected to the water pipe 36, so that the water in the water pipe 36 enters the flow channel 334; the contact between the arc strip 33 and the inner wall of the chamber can prevent the cooling water from flowing out from the gap between the arc strip 33 and the chamber after entering the chamber.

[0032] When the cutting depth is less than the preset standard depth, the water pressure of the water pump is judged to be low pressure, and the handle 331 drives the arc strip 33 to move, and the arc strip 33 moves in a direction away from the water outlet hole 323. One end of the arc strip 33 passes through the opening of the arc chamber and extends from the bottom surface of the shielding member 31, so as to shield the cooling water splashed during the cutting process of the cutting blade 22. The cooling water in the water pipe 36 will flow into the chamber. At this time, the joint 335 is not connected to the water pipe 36, and the joint 335 moves in a direction away from the water pipe 36. At this time, the water outlet hole 323 is exposed, and the water outlet hole 323 is closer to the water outlet end of the water pipe 36 than the joint 335. The cooling water entering the chamber will drip onto the cutting blade 22 through the water outlet hole 323 for cooling.The cutting depth may need to be adjusted during the cutting process. When the cutting depth is greater than the preset standard depth, the water pressure of the water pump is judged to be high pressure. At this time, the water supply pressure of the water pump increases, and the operator can manually press the protrusion 332 into the receiving groove to make the protrusion 332 leave the card slot 314. At this time, the arc strip 33 can move, and the arc strip 33 is driven to rotate by the handle 331. The arc strip 33 moves toward the connecting plate 321, so that the joint 335 can be connected to the water outlet end of the water pipe 36. After the arc strip 33 moves into place, the protrusion 332 is re-entered into the corresponding card slot 314, and the protrusion 332 is moved to the connecting plate 321. When the first spring enters the slot 314, the first spring is still in a compressed state, so that the protrusion 332 is in close contact with the slot 314 to prevent the arc strip 33 from moving. When the arc strip 33 moves toward the connecting plate 321, the scraper strip 322 can scrape off the impurities and the like remaining when the bottom surface of the arc strip 33 blocks the splashing cooling water, and as the arc strip 33 rotates, the protrusion 333 will cover the water outlet 323. At this time, the cooling water remaining between the baffle plate and the arc strip 33 will be squeezed, so that the pressure of the cooling water remaining between the baffle plate and the arc strip 33 on the outer wall of the water pipe 36 increases. Since the pressure of the cooling water in the water pipe 36 is increased due to the water The pressure of the pump increases. The increased pressure of the cooling water in the water pipe 36 on the water pipe 36 may cause the connection position of the hose and the hard part of the water pipe 36 to form a bulge due to the increase in water pressure, which may easily cause damage to the water pipe 36. The cooling water remaining between the baffle and the arc strip 33 is squeezed, so that the pressure of this part of the cooling water on the outer wall of the water pipe 36 increases inward, so as to offset the pressure of the cooling water in part of the water pipe 36 on the water pipe 36 outward, and avoid bulging and deformation of the water pipe 36. After the water pipe 36 is connected to the joint 335, the cooling water in the water pipe 36 enters the chamber after passing through the flow channel 334 and is After the shape is guided, it is sprayed from the bottom surface of the shielding member 31. When the cooling water flows through the opening of the chamber, the scraper 322 can be rinsed. When the cutting depth is deep, the part of the cutting blade 22 away from the first moving component will be tilted to facilitate cutting at a deeper depth. At this time, if the cooling water is sprayed to the cutting blade 22 through the water outlet 323, the cutting blade 22 cannot bring the cooling water to the deeper position of the cutting. Therefore, the cooling water is guided to spray directly between the cutting blade 22 and the concrete through the chamber, so that the cooling water can be sprayed into the deeper position of the cutting, directly to the position where the cutting blade 22 contacts the concrete for cutting, ensuring the effect of cooling and heat dissipation. ;
