Description

Technical Field

[0001] The utility model relates to a profile grinding machine which can automatically collect powder and reduce noise. Background Art

[0002] After grinding, the operator of the existing concrete profile grinder needs to reach into the device and brush off the powder remaining on the wall. This operation poses a major safety hazard. In addition, the right-angle and square design of the existing grinder easily causes powder accumulation, which is difficult to clean and affects the next use. Secondly, after collecting the powder, it is necessary to sifte the powder, which causes dust pollution. Finally, the grinding process generates a lot of noise, causing noise pollution and endangering human health. Utility Model Content

[0003] The present invention improves the above-mentioned problem. That is, the technical problem to be solved by the present invention is to provide a profile grinder that automatically collects powder and reduces noise. The profile grinder has a simple structure and is easy to use. It can not only reduce the safety hazards of cleaning the powder generated by grinding, but also better clean and filter the powder generated by grinding, thereby improving work efficiency.

[0004] The utility model is constructed as follows: it includes a casing and a plurality of air nozzles arranged at the upper inner portion of the casing; a feed port for inserting a concrete sample is provided on one side of the casing; a grinding device for grinding the concrete sample is provided inside the casing relative to the feed port; a dust collector is provided at the discharge port at the lower portion of the casing; and a dust collector filter is provided inside the dust collector.

[0005] Furthermore, the air nozzle is connected to an air pump arranged outside the casing through a conduit.

[0006] Furthermore, the casing includes a shell and a shell cover arranged above the shell, and the shell and the shell cover both include an inner shell and an outer shell, and a sound-absorbing cotton layer is arranged between the inner shell and the outer shell.

[0007] Furthermore, the corners in the housing are all arc-shaped.

[0008] Furthermore, the grinding device includes a grinding wheel, a motor and a drive shaft. The drive shaft passes through the housing, one end of the drive shaft is connected to the grinding wheel, and the other end is connected to the motor.

[0009] Compared with the prior art, the utility model has the following beneficial effects: the device has a simple structure, reasonable design, and is easy to use. The concrete test block to be ground is placed into the casing through the feed port, and the position of the test block is adjusted to align with the grinding area; the grinding device is started to start the grinding work; when the grinding is completed, the dust and debris are blown downward through the air nozzle and enter the dust collector filter in the dust collector to ensure that all powder and debris are collected in the dust collector and the screening work is completed; the dust collector is opened to collect the powder therein; after the collection is completed, the dust collector is replaced and the next grinding work is carried out. This device uses an air pump and an air nozzle to effectively collect the powder and debris generated during the grinding process, reducing the operator's cleaning work and improving work efficiency. Secondly, the air nozzle and air pump cleaning method and the arc-shaped inner wall design solve the problem of traditional grinders being dusty and difficult to clean. The right angles and sharp angles inside the grinder are transitioned into arcs to reduce the accumulation of powder and residues. In addition, filling the casing with sound-absorbing cotton greatly reduces the noise generated during the grinding process, improving the working and living environment.
