[0023] The present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0024] See attached Figures 1 to 4 , which is a schematic diagram of the main structure of a wall corner root cleaning device. The wall corner root cleaning device provided in this embodiment includes a cutter head 1, which includes a cutter holder 2 and a plurality of cutter head blocks 3 fixed to the outer surface of the cutter holder 2. A connecting rod 4 protrudes outward from the bottom center of the cutter holder 2. The cutter head 1 is connected to the end of the boom of an industrial robot 5 through the connecting rod 4, and is driven to rotate by the motor at the end of the boom. The cutter holder 2 is made of carbon structural steel, and the cutter head blocks 3 are made of tool steel.

[0025] The tool holder 2 is in the shape of a cone; the multiple cutter blocks 3 are divided into multiple cutter block groups, and the cutter blocks 3 of each cutter block group are evenly distributed on the outer surface of the tool holder 2 at equal intervals and are located at the same contour line. That is, from top to bottom, the cutter blocks 3 on the tool holder 2 are arranged in layers, and the multiple cutter blocks 3 in each layer correspond to one cutter block group. The cutter block 3 located at the top of the tool holder 2 is semi-conical and partially protrudes from the tool holder 2. The remaining cutter blocks 3 are trapezoidal blocks that are narrow at the top and wide at the bottom, so that the cutter block 3 has a certain width to ensure the strength of the cutter block 3. The number of cutter blocks 3 in the corresponding cutter block groups increases from top to bottom. The cutter blocks 3 of the upper and lower adjacent cutter block groups are staggered along the up and down directions of the tool holder 2 to reduce vibration during operation.

[0026] The outer surface of the cutter head block 3 coincides with the envelope surface of the cutter head 1. The included angle between the outer envelope line of the cutter head 1 and the bottom surface is less than 90°. In this embodiment, the included angle between the outer envelope line of the cutter head 1 and the bottom surface is 60°.

[0027] When in use, the cutter head 1 is mounted on the drive motor at the end of the arm of the industrial robot 5. The industrial robot 5 can be a self-propelled single-arm six-axis robot. The walking speed and direction of the robot are controlled by the operator; the robot's detection of surrounding obstacles is achieved by the robot's own sensors. For example, a sensor disk is installed at the top of the first section of the robot's arm. The sensor disk is semicircular and rotates axially with the first section; the sensor disk is equipped with multiple downward sensors for detecting the ground height. Its function is to use the sensor detection results to calculate the average ground height when the ground is uneven, so as to guide the positioning of the cutter head 1. Afterwards, the robot adjusts the arm so that the envelope line of the cutter head 1 is parallel to the wall surface for wall root cleaning; and the envelope line of the cutter head 1 is parallel to the ground for ground root cleaning. Since the cone angle of the cutter head 1 is less than 90°, it can realize the root cleaning of the dead corner between the double-sided wall and the ground, and it can also realize the root cleaning of the special-shaped wall whose angle is greater than the cone angle of the cutter head 1.

[0028] The above are the preferred embodiments of the utility model and the technical principles used therein. For those skilled in the art, without departing from the spirit and scope of the utility model, any obvious changes such as equivalent transformation, simple replacement, etc. based on the technical solution of the utility model shall fall within the protection scope of the utility model.
