A kind of multi-functional high-efficiency grinding machine

Abstract

The invention discloses a multifunctional efficient ground-grinding machine. The multifunctional efficient ground-grinding machine comprises a machine frame, a water tank arranged on the machine frame and wheels arranged at the bottom of the machine frame. An operating handle for pushing the machine frame to move is arranged on the rear side of the machine frame. A grinding disc assembly and a driving device for driving the grinding disc assembly to move are arranged on the front side of the machine frame. An overload protecting mechanism is arranged between a transmission mechanism and the grinding disc assembly, and the minimum shearing stress of the overload protecting mechanism is smaller than that in the transmission mechanism. When the ground-grinding machine operates, if the impact load borne by the grinding disc assembly is larger than the minimum shearing stress of the overload protecting mechanism, the transmission connection between the overload protecting mechanism and the grinding disc assembly breaks automatically by the overload protecting mechanism, and the transmission mechanism is effectively prevented from being damaged. When the ground-grinding machine needs to continue to be used, it is only needed to replace accessories on the overload protecting mechanism. The multifunctional efficient ground-grinding machine has the characteristics that replacement is convenient, time and labor are saved, and the maintenance cost is low.

Description

[0001] 【Technical field】 [0002] The invention relates to a ground grinder, in particular to a multifunctional high-efficiency ground grinder. [0003] 【Background technique】 [0004] When the ground grinder is working, due to the different working sites, the resistance received by the grinding plate is also different, so that the transmission mechanism of the ground grinder is often subjected to different reaction impact forces, and the transmission mechanism of the ground grinder is generally carried out by a gear mechanism. Transmission, when the impact force on the grinding plate exceeds the minimum shear stress in the gear mechanism, the gear mechanism will produce a toothing phenomenon, which will cause the tooth root of the gear to break and be damaged; in order to ensure normal operation, it is necessary to repair the damaged gear Replacement, and the replacement of the gears has a higher cost, is also inconvenient to disassemble, and is more time-consuming, resulting ...

[0004] When the ground grinder is working, due to the different working sites, the resistance received by the grinding plate is also different, so that the transmission mechanism of the ground grinder is often subjected to different reaction impact forces, and the transmission mechanism of the ground grinder is generally carried out by a gear mechanism. Transmission, when the impact force on the grinding plate exceeds the minimum shear stress in the gear mechanism, the gear mechanism will produce a toothing phenomenon, which will cause the tooth root of the gear to break and be damaged; in order to ensure normal operation, it is necessary to repair the damaged gear Replacement, and the replacement of the gear is relatively expensive, and it is not easy to disassemble and assemble, which is more time-consuming, resulting in higher maintenance costs of the ground grinding machine in the prior art
