[0002] Polishing machine is also called grinding machine, which is often used for mechanical grinding, polishing and waxing. Its working principle is: the motor drives the sponge or wool polishing disc installed on the polishing machine to rotate at high speed. Due to the joint action of the polishing disc and the polishing agent and the friction with the surface to be polished, the paint surface pollution, oxide layer and shallow marks can be removed. Most of them are stepless speed change, which can be adjusted at any time according to the needs during construction. When the polishing machine is working, a lot of dust is generated, and these dusts often need to be collected by corresponding collection devices to avoid environmental pollution;

[0003] However, the dust collection device of the current polishing machine often requires regular manual cleaning of the dust bag or dust box after dust collection, and cannot automatically clean the dust, which is time-consuming and labor-intensive. In addition, the accumulation of dust often blocks the exhaust holes, weakening the wind force and thus affecting the dust collection quality.

[0004] Therefore, how to provide a dust collecting device for a polishing machine is a problem that those skilled in the art need to solve urgently. Utility Model Content

[0008] The dust collection cylinder is transversely embedded and installed inside the dust collection box. A cavity is provided inside the dust collection box. The air outlet of the fan is connected to the cavity. A notch is provided on the top of the dust collection cylinder. A plurality of exhaust microholes are provided on the bottom of the dust collection cylinder. An auger blade is rotatably installed inside the dust collection cylinder. A motor is fixedly installed at the front end of the dust collection cylinder. The output shaft of the motor is drivingly connected to the auger blade.

[0009] Optionally, a dust outlet is integrally formed at the bottom of the dust removal cylinder close to the motor.

[0024] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0025] refer to Figure 1-3 , a dust collecting device for a polishing machine, comprising a dust collecting box 1, a dust collecting hood 4 and a dust collecting cylinder 8;

[0026] An electric push rod 2 is fixedly installed on one side of the top of the dust box 1, a support arm 3 is fixedly installed on the top of the electric push rod 2, a dust cover 4 is fixedly installed on the bottom of the other side of the support arm 3, a fan 5 is fixedly installed on the outer wall of the dust box 1 close to the dust cover 4, a bellows 6 is installed on the air inlet on the top of the fan 5, and the other end of the bellows 6 is connected to each other at the top of the dust cover 4;

[0027] The dust collecting cylinder 8 is transversely embedded and installed inside the dust collecting box 1. A cavity 15 is provided inside the dust collecting box 1. The air outlet of the fan 5 is connected to the cavity 15. A notch 13 is provided on the top of the dust collecting cylinder 8. A plurality of exhaust micro holes 16 are provided on the bottom of the dust collecting cylinder 8.

[0028] Among them, universal wheels 12 are fixedly installed at the four corners of the bottom of the dust box 1 to facilitate the movement of the equipment, thereby greatly improving the flexibility of the equipment when used;

[0029] Secondly, an exhaust port 11 is provided at the lower part of the outer wall of the other side of the dust box 1, and the exhaust port 11 and the cavity 15 are interconnected, so that the exhaust port 11 can ensure that the air can be smoothly discharged from the cavity 15 when the fan 5 is working;

[0030] In this embodiment, after the equipment moves to one side of the polishing machine, the electric push rod 2 is started to drive the dust hood 4 to rise and fall, so the dust hood 4 can be suitable for polishing machines of different heights. Then the fan 5 can be started to suck air, and the dust generated by the polishing machine during operation can be sucked into the cavity 15 through the bellows 6, and finally the dust can fall into the dust collection tube 8, and finally the air can be discharged through the exhaust micropores 16 and the exhaust port 11, and the dust is retained in the dust collection tube 8 to achieve the purpose of dust collection, thereby effectively improving the environmental protection of the polishing machine during operation.

[0031] refer to Figure 1-3 A screw blade 14 is rotatably mounted inside the dust removal cylinder 8, a motor 10 is fixedly mounted at the front end of the dust removal cylinder 8, and the output shaft of the motor 10 is drivingly connected to the screw blade 14;

[0032] Among them, a dust outlet 9 is integrally formed at the bottom of the dust removal cylinder 8 near the motor 10;

[0033] In addition, a control panel 7 for controlling the fan 5, the motor 10 and the electric push rod 2 is fixedly installed on one side of the top of the dust box 1;

[0034] In this embodiment, when the fan 5 starts working, the motor 10 can be synchronously turned on to drive the auger blades 14 to be selected. At this time, the dust collected in the dust collection tube 8 can be transported to the side of the dust discharge port 9 under the rotation of the auger blades 14, and finally discharged through the dust discharge port 9. When in use, it only needs to be located at the bottom of the dust discharge port 9 to prevent the collection bag from completing the dust collection. Therefore, the dust can be cleaned in time and automatically, and excessive dust accumulation can be prevented to cause the exhaust micropores 16 to be blocked, thereby affecting the wind force and weakening the dust suction effect.

[0035] It is understandable that the fan 5, the electric push rod 2 and the motor 10 in the utility model can be driven by an external power line, and the fan 5, the electric push rod 2 and the motor 10 can be controlled by the control panel 7, and the control principle can be realized by the existing control technology. The model of the fan 5, the electric push rod 2 and the motor 10 is not limited to a single type and can be a type that is suitable for the utility model on the market.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
