Description

Technical Field

[0001] The invention belongs to the technical field of floor grinders, and in particular relates to a floor grinder with adjustable grinding pressure based on ground hardness. Background Art

[0002] A floor grinder is a special machine used for grinding floors of various materials and hardness, such as concrete floors, emery floors, and colored stone floors. It can make the floor smooth and flat through grinding and polishing.

[0003] There are many types of floor grinders currently on the market, but these grinders all have a common defect in use. For example, the existing grinders cannot flexibly adjust the appropriate grinding pressure to adapt to the ground according to the different hardness of the ground to be treated during use. Different ground surfaces can only be treated by replacing grinding discs with different sharpness. However, there are many types of grinding discs on the market, which makes it difficult for construction workers to choose. In addition, the performance and usage methods of different grinding discs are different. When construction workers use different grinding discs to work, over-grinding or under-grinding is likely to occur. Construction workers need to grind multiple times before they can gradually explore the ideal grinding operation method, which is rather troublesome.

[0004] In order to solve the defects of existing grinders, some improved grinders control and adjust the floor grinding treatment method by adjusting the rotation speed, traveling speed or adding counterweights, but these treatment methods are still difficult to meet the grinding construction needs of different floors.

[0005] During long-term practical operations, the applicants found that floor grinding is affected by multiple factors, such as cutting speed, travel speed, and grinding pressure depth. Although the existing grinders on the market can control the cutting speed and travel speed, they cannot meet the needs of flexible adjustment of the grinding pressure. Therefore, this application proposes a grinder that can flexibly adjust the grinding pressure to cope with floors of different hardness and different materials. Summary of the invention

[0006] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a floor grinder with adjustable grinding pressure based on the ground hardness, so as to solve the problem that the current floor grinders on the market cannot flexibly adjust the grinding pressure.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A floor grinding machine with adjustable grinding pressure based on ground hardness, comprising:

[0009] A mounting frame, with a roller rotatably connected to the mounting frame;

[0010] A mill, hinged to the mounting frame through a rotating shaft;

[0011] A mounting plate, fixedly connected to the mounting frame, and an electric telescopic rod is fixedly connected to the mounting plate. A counterweight is fixedly connected to the end of the electric telescopic rod, and the counterweight is slidably connected to the mounting frame;

[0012] A controller, fixedly connected to the counterweight.

[0013] Preferably, a plurality of pulleys are rotatably connected to the mounting frame, and a slide rail abutted against the pulleys is connected to the counterweight.

[0014] Preferably, the counterweight is arranged in a concave shape, and the notch of the counterweight faces the mill.

[0015] Preferably, a handrail is connected to the counterweight.

[0016] Preferably, universal wheels are connected to the counterweight.

[0017] Preferably, the controller is electrically connected to the electric telescopic rod.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] By arranging a mill, a movable counterweight, an electric telescopic rod and a controller on the mounting frame, the user can not only control the cutting speed of the mill through the controller, but also control the traveling speed of the mill through the controller. At the same time, the user can control the electric telescopic rod to extend and retract through the controller. The extended and retracted electric telescopic rod drives the counterweight to move on the mounting frame. As the position of the counterweight on the mounting frame changes, the overall center of gravity of the equipment will change, thereby causing the pressure received by the mill to change. The user can flexibly adjust the grinding pressure of the mill by controlling the extension and retraction of the electric telescopic rod to meet the grinding treatment requirements of different materials and different hardness floors.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0026] Embodiment:

[0027] Refer to Figures 1-4 , a floor grinding machine capable of adjusting the grinding pressure based on the ground hardness, comprising:

[0028] Mounting frame 1, on which a roller 4 is rotatably connected;

[0029] Grinding machine 3, hinged to the mounting frame 1 through a rotating shaft 2;

[0030] Mounting plate 5, fixedly connected to the mounting frame 1, and an electric telescopic rod 6 is fixedly connected to the mounting plate 5. The end of the electric telescopic rod 6 is fixedly connected to a counterweight 7, and the counterweight 7 is slidably connected to the mounting frame 1;

[0031] Controller 10, fixedly connected to the counterweight 7, and the controller 10 is electrically connected to the electric telescopic rod 6.

[0032] As can be seen from the above, by arranging the grinding machine 3, the movable counterweight 7, the electric telescopic rod 6 and the controller 10 on the mounting frame 1, the user can not only control the cutting speed of the grinding machine 3 through the controller 10, but also control the traveling speed of the grinding machine 3 through the controller 10. At the same time, the user can control the electric telescopic rod 6 to extend and retract through the controller 10. The extended and retracted electric telescopic rod 6 drives the counterweight 7 to move on the mounting frame 1. As the position of the counterweight 7 on the mounting frame 1 changes, the overall center of gravity of the device will change, thereby causing the pressure received by the grinding machine 3 to change. The user can flexibly adjust the grinding pressure of the grinding machine 3 by controlling the extension and retraction of the electric telescopic rod 6 to meet the grinding treatment requirements of floors of different materials and different hardnesses.

[0033] Refer to Figures 3-4A plurality of pulleys 9 are rotatably connected to the mounting frame 1, and a slide rail 8 that abuts against the pulleys 9 is connected to the counterweight 7. When the electric telescopic rod 6 drives the counterweight 7 to move, the counterweight 7 can slide on the pulleys 9 through the slide rail 8, converting static friction into rolling friction, which helps the counterweight 7 to move. At the same time, it is beneficial for the electric telescopic rod 6 to accurately control the moving distance of the counterweight 7, realizing the refined control of the overall center of gravity of the equipment, and thus realizing the refined control of the grinding pressure of the mill 3.

[0034] The counterweight 7 is arranged in a concave shape, and the notch of the counterweight 7 faces the mill 3, which is convenient for the movable counterweight 7 to move above the mill 3, so that the adjustment range of the grinding teeth of the mill 3 is larger.

[0035] A handrail 11 is connected to the counterweight 7, and the user can push the equipment to move through the handrail 11.

[0036] A universal wheel 12 is connected to the counterweight 7. When the electric telescopic rod 6 extends and pushes the counterweight 7 to the outermost end of the mounting frame 1, the center of gravity of the counterweight 1 crosses the rotation axis of the roller 4. At this time, the gravity of the counterweight 7 will drive the entire mounting frame 1 to rotate until the universal wheel 12 contacts the ground. At this time, the entire equipment is supported on the ground by the roller 4 and the universal wheel 12, and the mill 3 is located on the side of the mounting frame 1, so that the bottom grinding disc of the mill 3 is exposed, which is convenient for the user to replace the grinding disc of the mill 3 according to needs.

[0037] To enhance the durability of the equipment, the mounting frame 1, the rotating shaft 2, the handrail 11 and the slide rail 8 are all made of stainless steel. In addition to stainless steel, the user can also replace other materials according to the usage conditions, not limited to stainless steel materials.

[0038] In one embodiment, the user can also install a storage battery on the equipment to supply power to the electric telescopic rod 6, the mill 3 and the controller 10 through the storage battery, avoiding the limitation of the usage area of the equipment due to the connection wires. By carrying a movable storage battery as an independent power supply, it is convenient for the user to push the equipment to transfer the construction site.

[0039] When specifically manufacturing the equipment, an outer cover can be installed to cover the counterweight, the electric telescopic rod and other equipment, which can not only improve the aesthetic degree of the equipment, but also improve the use safety of the overall equipment, and can also play a certain protective role for each internal component. The user can also add other functional components according to needs, and all those within the scope of the use principle of this application are within the protection scope of this application.
