Problems solved by technology
At present, there are various kinds of floor sanders used for this work on the market, but most of them have the following deficiencies: 1. The machine vibrates greatly, which affects the comfort of operation on the one hand, and causes dust to easily enter on the other hand The motor affects the cleanliness inside the motor, and ultimately affects the output efficiency of the motor; 2. The structure is complex and the operation is inconvenient; 3. The volume is large, which is not conducive to storage and carrying; 4. The dust collection effect is poor, and the working environment needs to be improved

The invention relates to a floor dull-polishing machine which comprises a handle, a working head, a dull-polishing component and a dust absorbing mechanism. A motor and a motor rotor shaft are arranged in the working head. A dull-polishing component fixing disc is arranged at the bottom of the working head. The dull-polishing component is arranged on the dull-polishing component fixing disc. The lower end of the motor rotor shaft extends out of the dull-polishing component fixing disc. The extending-out end of the motor rotor shaft is provided with an eccentric structure. The dull-polishing component is in matching connection with the eccentric structure through a bearing. A dustproof sealing ring and a balance block are arranged on the motor rotor shaft in a sleeved mode. The dustproof sealing ring is placed in a hole, for the motor rotor shaft to extend out, in the dull-polishing component fixing disc. The balance block is arranged close to the bearing. According to the dull-polishing machine, vibration of the machine can be lowered, operation comfort is improved, the problem that dust enters the motor during working is effectively avoided, cleanliness in the motor is guaranteed, the output efficiency of the motor is improved, in addition, structure is simple, size is small, handle length and angle can be adjusted, operation is convenient, and carrying and storing are benefited.
Description
Technical field: [0001] The invention relates to a sander used for leveling, grinding and polishing floors, and belongs to the field of electric tools for building decoration. Background technique: [0002] In the construction process of floor laying, the entire plane of the floor needs to be leveled, and its function is to improve the flatness of the entire plane of the floor and at the same time improve the smoothness of the floor surface. At present, there are various kinds of floor sanders used for this work on the market, but most of them have the following deficiencies: 1. The machine vibrates greatly, which affects the comfort of operation on the one hand, and causes dust to easily enter on the other hand The motor affects the internal cleanliness of the motor, and ultimately affects the output efficiency of the motor; 2. The structure is complex and inconvenient to operate; 3. The volume is large, which is not conducive to storage and carrying; 4. The dust collection...
