[0028] Example 1: Refer to Figure 1 , Figure 2 and Figure 3 , a cutter head device on an electric bark scraping device, which includes a tool holder 1 and a blade 2. The tool holder 1 is evenly spaced with blades 2. The two ends of the blade 2 are correspondingly welded to the inner end face of the tool holder 1. This setting avoids the overall exposure of the blade 2 outside, reduces the occupied space, and the blade 2 and the tool holder 1 are integrally connected by welding, ending the clamping connection method between the tool holder 1 and the blade 2, greatly improving the stability and firmness of the connection between the tool holder 1 and the blade 2, avoiding loosening or detachment, and being beneficial to improving the stability, reliability and safety of use. The cutting edge of the blade 2 exposes from the circumference of the tool holder 1, and the cutting edges of the blade 2 all face the same direction. This setting is beneficial for cutting and is more practical. In this embodiment, six blades 2 are used, and the six blades 2 are evenly arranged on the circumference of the tool holder 1. This setting is reasonable and convenient to implement.
[0029] Example 2: It can be described on the basis of Example 1. As Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, the tool holder 1 includes a base 11 and a top cover 12. A number of mounting holes one 13 are evenly arranged on the base 11, and a number of mounting holes two 14 are evenly arranged on the top cover 12.

This setting is beneficial for quickly installing the blade 2, and the two ends of the blade 2 and the corresponding mounting holes one 13 and the mounting holes two 14 are integrally connected by welding, greatly improving the structural stability.
[0030] As Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, further explanation is that a round hole 111 is opened in the middle of the base 11. This setting is beneficial for better installation in the electric device for bark scraping and matching with the motor.
[0031] Example 3: It can be described on the basis of Example 2. As Figure 4 and Figure 5 shown, a gap 3 is provided between adjacent blades 2. Through the gap 3, it is more beneficial for the bark to flow out and is more beneficial for the continuous operation of the blade 2. Further explanation is that, as Figure 6As shown, the blade 2 includes a body 21. At both ends of the body 21, there are bumps 22 for installation in the first mounting hole 13 of the base 11 and the second mounting hole 14 of the top cover 12. A cutting edge 23 (knife edge) is provided on the body 21. This kind of setting is reasonable, with a simple structure, facilitating production and manufacturing, and being more conducive to the convenient and rapid installation with the tool holder 1.
