Problems solved by technology

Existing wall grinding machines (including those with handles or without handles), whose grinding discs are all driven by motors, have the following defects: 1. For grinders with handles, the motors are generally placed on the handles, For the grinding machine without handle, the motor is usually placed in the base of the grinding disc, so this kind of grinding machine is relatively heavy, not only inconvenient to operate, but also labor-intensive
2. For motor-driven grinding machines, the grinding disc is connected to the output shaft of the motor through a flexible shaft. Since the grinding disc rotates in one direction under the drive of the motor to grind the wall, it is easy to cause scratches on the wall and cause the wall to be powdered. quality issues after
3. Due to the heating of the motor, it is not suitable to work for a long time. If you work for a long time, it is easy to burn out the motor
[0003] At present, the pneumatic grinding machines on the market are generally used for grinding woodworking surfaces, and their power is provided by the motor. Due to the serious heating phenomenon of the motor during operation, the damage rate is very high.

Embodiment 1

[0019] Such as figure 1 As shown, the present invention includes a pneumatic grinding head 1 and a power unit 2 connected with the grinding head 1 . The power device is an air compressor, and the air compressor communicates with the socket of the grinding head frame 4 through a hose 3 .

[0020] still as figure 1 As shown, the grinding head 1 is provided with a handle 5 , and in this embodiment, the handle 5 is movably connected to the dust suction cover 6 provided on the grinding head 1 . The handle 5 is a hollow tube structure, and the flexible pipe 3 penetrates from one end of the handle 5 and then exits from the other end, and its two ends are respectively connected with the air compressor 2 and the grinding head support 4 sockets. In this embodiment, the dust collection hood 6 communicates with the vacuum cleaner through a suction pipe 8 (the illustration of the vacuum cleaner is not provided), and both ends of the handle 5 communicate with the dust collection pipe 8 re...

Embodiment 2

[0023] Such as figure 2 As shown, the grinding head 1 is provided with a suction cover 6 and a suction pipe 8 thereof, and the flexible pipe 3 penetrates from one end of the suction pipe 8 and passes out from the other end. Head 1 base socket connection.

[0024] All the other implementations are as in Example 1.

Abstract

The invention discloses a pneumatic wall surface sander, which comprises a pneumatic sanding head and a power device, wherein the power device is connected with the sanding head, and is an air compressor; and the air compressor is communicated with the jack of a sanding head base through a hose. 1, the pneumatic sanding head is adopted, the air compressor is used for supplying power to the pneumatic sanding head, and the air compressor and the pneumatic sanding head are arranged separately and are connected with each other through the hose, so that the handholding weight of the sanding head is reduced for an operator, and operation is convenient and easy; 2, the air compressor is used for supplying power to the pneumatic sanding head, and the hose for connecting the air compressor and the pneumatic sanding head is provided with a pressure relief valve, so that the pressure is controllable and the work is stable in the sanding process of a wall surface; and 3, due to the special operating mode of the pneumatic sanding head, the sanded wall surface is smooth and flat without any scratch, and the quality of a painted wall surface is ensured.

Description

technical field [0001] The invention relates to the construction field, in particular to a grinding device for wall surfaces before powder coating. Background technique [0002] As we all know, before the interior wall is powdered or painted, the wall putty must be polished with a grinder to make it smooth and smooth, so as to ensure the quality of the wall surface after powder coating. Existing wall grinding machines (including those with handles or without handles), whose grinding discs are all driven by motors, have the following defects: 1. For grinders with handles, the motors are generally placed on the handles, For the grinding machine without handle, the motor is generally placed in the support of the grinding disc, so this grinding machine is relatively heavy, not only inconvenient to operate, but also labor-intensive. 2. For motor-driven grinding machines, the grinding disc is connected to the output shaft of the motor through a flexible shaft. Since the grinding ...
