The cutterhead opens at the edge of the cutterhead and includes several blades with blades on one side. The blades are provided with a number of parallel scoring lines. The front ends of the blades can Break off along the scoring line, the blade is inserted into the groove from the edge of the cutterhead in the radial direction of the cutterhead, the two sides of the blade slide and fit with the groove walls on both sides of the groove, the front end of the blade has a tip located outside the groove, and the rear end of the blade is set There are threaded holes, and bolts are screwed in the threaded holes. The bolts tighten the bottom of the knife groove to fix the blade on the knife groove. It also includes several fixing rods, which are fixed on the top surface of the cutter head and fit on the adjacent The two score lines correspond to the top surface of the blade.

The blade is fixed in the knife groove and fixed by bolts, and the blade is made more stable by using the fixing rod. The cutter head is installed on the motor shaft through the mounting hole, and the cutter head is driven to rotate through the motor shaft. After damage, use the fixed rod as a support, break part of the blade upward along the score line, then loosen the bolt, stretch the blade outward and fix it, and then a new blade can be used, thus improving the service life of the tool.

Preferably, the edge of the cutter head is detachably connected with a positioning block, and the front edge of the blade abuts against the positioning block.

Utilizing the positioning block can ensure that each blade protrudes to the same length.

Preferably, the groove walls on both sides of the sipe are deepened near the rear end of the blade, and the two sides of the blade are slidingly fitted with the groove walls on both sides of the sipe.

So the blade is more stable.

Preferably, the cutter head is provided with several lightening holes distributed along the radial and circumferential directions of the cutter head.

Compared with the prior art, the utility model has the following advantages:

The blade is fixed in the knife groove and fixed by bolts, and the blade is made more stable by using the fixing rod. The cutter head is installed on the motor shaft through the mounting hole, and the cutter head is driven to rotate through the motor shaft. After damage, use the fixed rod as a support, break part of the blade upward along the score line, then loosen the bolt, stretch the blade outward and fix it, and then a new blade can be used, thus improving the service life of the tool.
