Belt transmission device of terrace grinding machine

Abstract

The invention discloses a belt transmission device of a terrace grinding machine. A box body and a box cover are included. The box cover is arranged above the box body. First through holes and secondthrough holes are formed in the bottom of the box body. Each second through hole is internally provided with a rotation shaft and a rotation rod, wherein one ends of the rotation rod and the rotationshaft are connected with grinding sheet devices. The rotation shafts are fixedly sleeved with first transmission belt wheels, and the rotation rods are fixedly sleeved with second transmission belt wheels. The bottom of the box body is provided with a mechanism connected with a motor output shaft, the mechanism drives the first transmission belt wheels and the second transmission belt wheels to rotate through a belt, and accordingly self-rotation of the grinding sheet devices is achieved. The rotation rods are connected through a transmission belt, the mechanism connected with the motor outputshaft is connected with a fixing disc, the fixing disc is fixedly connected with the box body, the fixing disc is attached to the inner side of the transmission belt, and accordingly revolution of the grinding sheet devices can be achieved. The device has good stability, and inconvenience that a worker needs to conduct direction adjustment multiple times is avoided.

Description

technical field [0001] The invention relates to the field of floor grinding and polishing machinery, in particular to a belt drive device for a floor grinder. Background technique [0002] The floor grinder is mainly used for ground grinding. It can effectively grind terrazzo, concrete surface, epoxy mortar layer and old epoxy floor. [0003] For example, the Chinese patent publication No. CN107650020A discloses a floor grinder grinding head transmission mechanism, its structure includes a first blade, a second blade, a transmission box, a third blade, and a fourth blade. , the second blade, the third blade, and the fourth blade are located on the same horizontal plane and are arranged below the transmission box, and the transmission box is connected with the transmission of the first blade, the second blade, the third blade, and the fourth blade; the transmission box It is composed of a first driven wheel, a transmission belt, a tensioning device, a second driven wheel, a ...

AI Technical Summary

Problems solved by technology

[0004] The above technical solution is that the belt drives the four rotating shafts to rotate, thereby driving the blades fixedly connected to the rotating shafts to rotate, and the blades all rotate in the same direction. Since the blades all rotate in one direction, the device tends to be biased when it is pushed, and requires work. Personnel frequently adjust its moving direction, and the blade can only rotate by itself, and the grinding effect is average
