Description

Technical Field

[0001] The utility model belongs to the technical field of grinding equipment auxiliary tools, and in particular relates to a small grinding equipment driving assembly. Background Art

[0002] Floor grinders are mainly used for grinding the ground. They can effectively grind terrazzo, concrete surface, epoxy mortar layer and old epoxy floor, etc. Floor polishers are used to grind and polish marble, ceramic tile and other surface bottom surfaces. They are light, flexible and efficient. There are many types of grinding equipment. Floor grinders are generally composed of a main unit, a grinding unit and an ash receiving unit. The grinding unit is arranged at the front bottom of the main unit, and the ash receiving unit is installed at the rear bottom of the main unit. Large grinding equipment can be equipped with a drive structure, which makes it easier for the staff to push the grinding equipment to move. However, due to the compact structure of small grinding equipment, it is not convenient to install a drive structure. Therefore, small grinding equipment is generally moved by manual pushing of the staff. Moreover, when using small grinding equipment, due to the continuous wear of the grinding disc, when using small grinding equipment, it is necessary to lift the grinding equipment gently by the staff holding the push handle according to the wear of the grinding disc, so that the grinding disc can be lowered so that the grinding disc can continue to grind the floor. However, this process consumes a lot of physical strength of the staff, which will reduce the grinding efficiency of the floor. Utility Model Content
