a sliding groove which is vertical to the sliding direction of the grinding plate is arranged on the driving plate; one end of the pendulum shaft can slide in the sliding groove, the other end of the pendulum shaft is fixedly connected with the position, close to the periphery, of the bottom of the disc after vertically extending, so that the driving plate can horizontally slide through the pushing of the pendulum shaft under the rotation of the disc, and the grinding plate can horizontally slide relative to the support plate to grind the surface of concrete.

The beneficial effect of adopting the further scheme is that: the grinding plate horizontally slides relative to the support plate under the driving of the speed reducing motor so as to grind the surface of the concrete.

Further, the device also comprises a connecting frame and a handle; one end of the connecting frame is fixedly connected to one side of the support plate, the other end of the connecting frame is connected with a handle which is used for manually dragging the grinding plate to grind different positions on the surface of the concrete, and a button which is used for controlling the speed reducing motor to operate or be closed is arranged on the handle.

Further, the grinding plate grinding machine also comprises a roller assembly used for transferring the grinding plate, and the roller assembly is arranged at the bottom of the connecting frame.

The beneficial effect of adopting the further scheme is that: the control and transfer of the grinder are facilitated.

Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.

As shown in fig. 1 and 2, a concrete grinder includes a grinding plate 1, a holder plate 2, and a reduction motor 3. The grinding plate 1 is of a plate structure with the periphery upwards rolled and the bottom smooth, and linear bearing guide rails 4 are horizontally fixed on two sides of the top of the grinding plate 1 respectively. The support plate 2 is positioned above the grinding plate, and the linear bearing guide rail 4 is connected with the support plate 2 through a linear bearing 13 so as to realize that the grinding plate 1 can horizontally slide relative to the support plate 2. The speed reducing motor 3 is arranged on the support plate 2 and is connected with the swing assembly and drives the grinding plate 1 to horizontally slide relative to the support plate 2 so as to grind the concrete surface.

As shown in fig. 3, the swing assembly includes a driving plate 5, a disc 6, and a swing shaft 7. And two ends of the driving plate 5 are bent downwards and then fixed on the grinding plate 1 at positions corresponding to the speed reducing motor 3. The disc 6 is positioned between the support plate 2 and the driving plate 5, and the disc 6 is connected with the output end of the speed reducing motor 3. The driving plate 5 is provided with a sliding groove 8 perpendicular to the sliding direction of the grinding plate 1. One end of the pendulum shaft 7 can slide in the chute 8, and the other end of the pendulum shaft extends vertically and then is fixedly connected with the position, close to the periphery, at the bottom of the disc 6, so that the driving plate 5 is pushed to slide horizontally through the pendulum shaft 7 under the rotation of the disc 6, and the grinding plate 1 can slide horizontally relative to the support plate 2 to grind the surface of concrete.

The grinder also comprises a connecting frame 9, a handle 10 and a roller assembly 12 for transferring the grinding plate 1. One end of the connecting frame 9 is fixedly connected to one side of the support plate 2, the other end of the connecting frame is connected with a handle 10 which is used for manually dragging the grinding plate 1 to grind different positions of the concrete surface, and a button 11 which is used for controlling the speed reducing motor 3 to run or be closed is arranged on the handle 10. The roller assembly 12 is mounted at the bottom of the connecting frame 9.

During work, the handle 10 is held by hand and the button 11 is triggered to start the speed reducing motor 3, the speed reducing motor 3 drives the disc 6 to rotate, the disc 6 drives the swing shaft 7 to slide in the chute 8 on the driving plate 5 after rotating, the swing shaft 7 slides in the chute 8, meanwhile, under the guidance of the linear bearing guide rail 4 and the linear bearing 23, the swing shaft 7 pushes the driving plate 5 to horizontally slide, namely, swing left and right, the driving plate 5 synchronously drives the grinding plate 1 to swing left and right, and the grinding plate 1 can realize the grinding of the concrete surface by swinging left and right.
