Ground leveling machine with adjustable gravity center

Abstract

The invention discloses a ground leveling machine with an adjustable gravity center. The machine comprises a rack, a motor driving device is fixed to the front section of the rack, a grinding disc is connected with the motor driving device, and roller shafts are arranged on the two sides of the rack and are provided with rollers; and the machine further comprises a moving device and a counter weight device which are arranged on the plane of the middle section of the rack, wherein the counter weight device is fixedly installed on the moving device and can move in the front-back direction through the moving device. The leveling machine has the advantages that a sliding device is adopted, the front-back weight of the whole leveling machine can be adjusted by one hand, adjustment is stable, the counter weight device can bear large gravity, stepless adjustment of the counter weight of the leveling machine is achieved, a grinding gravity center of the grinding disc is adjusted accordingly, labor force is reduced, the grinding disc is convenient to adjust and maintain, action is reliable, and transportation and movement are convenient; and the roller shafts are connected with a distribution box support, and the distribution box support is connected with a handle support through a damping device, so that vibration is absorbed, damage of the vibration to the distribution box is reduced, and the maintenance cost is reduced.

Description

Problems solved by technology

[0003] At present, the commonly used ground leveling machine on the market includes a frame. The front part of the frame is fixed with a motor drive device. The drive device is connected to the grinding disc. It is necessary to change the downforce of the grinding disc for speed, grinding position and angle, and when changing the grinding head or abrasive, it is necessary to lift the handle and lower the pedal. The worker stands on the pedal and uses the gravity inertia of the whole body to Press to realize the lifting of the grinding disc, and then replace the abrasive, which has certain requirements on the physical strength of the operator. If the grinding equipment is large, multiple people are needed to replace the grinding head. In the prior art, the leveling machine The pressing method is labor-intensive, time-consuming, labor-intensive, inefficient, inconvenient, and unsafe

[0004] When the commonly used ground grinding machine cannot adjust the center of gravity position and pressure of the ground ground ground by the grinding disc, although Chinese patent CN204976221U discloses a grinding machine with a counterweight device, the weight of the ground ground ground ground by the grinding disc can be adjusted by the counter weight device. The position and pressure of the center of gravity can also help workers save effort when lifting the grinding disc, but the counterweight device still requires high-intensity manpower to rotate the configuration device, and the counterweight device can only be fixed at the front or rear end of the grinder. a fixed position, and the weight of the counterweight cannot be adjusted, and stepless adjustment cannot be realized

[0005] In addition, due to the large vibration of the machine when it is working, the requirements for the shock resistance of the electrical part are relatively high. Ordinary leveling machines usually directly install the electrical part on the frame. Some parts are directly connected, so the vibration of the motor and the grinding disc is directly transmitted to the frame, which eventually leads to a large vibration of the electrical part, resulting in hazards such as electrical wiring falling off and component damage

[0006] For example, Chinese patent application CN108044498A discloses a direct-connected grinder, which directly puts the power supply and the motor together, which will inevitably cause the power supply to vibrate very large, and the circuit is prone to poor contact, and even falls off to cause the risk of electric shock
