Description

Technical Field

[0001] The present application relates to the technical field of dust removal for milling machines, and more specifically, to a dust removal structure for milling machines. Background Art

[0002] The dust removal structure of the milling machine is a device specially designed for the milling machine to remove dust and debris generated during the processing. When the milling machine is working, the dust suction port is close to the processing area, and the dust and debris are sucked into the pipe by the suction force generated by the fan. After being filtered by the filter, the clean air is discharged, and the dust and debris are collected, thereby maintaining a clean working environment and reducing the impact on the health of the operator. At the same time, it also helps to protect the milling machine equipment and increase its service life.

[0003] However, traditional milling machines usually do not have a special dust removal structure, which causes dust to spread in the working area, which not only seriously affects the cleanliness of the working environment and causes great harm to the health of the operators, but also the dust can easily enter the interior of the milling machine, causing wear on the key components of the equipment and reducing the service life of the milling machine. At the same time, some existing simple dust removal devices are prone to dust adsorbed on the inner wall of the filter when filtering dust, affecting the ventilation effect, thereby reducing the dust removal efficiency and failing to meet the needs of efficient and clean production.

[0004] In view of this, we propose a dust removal structure for a milling machine. Utility Model Content

[0020] The present application is further described in detail below with reference to the accompanying drawings.

[0021] Reference Figure 1-Figure 3 The embodiment of the present application provides a dust removal structure for a milling machine, comprising an inclined dust removal frame 1, wherein a precision filter cylinder 8 is provided inside the dust removal frame 1. The dust removal frame 1 and the precision filter cylinder 8 can effectively filter dust in the air, prevent dust from spreading in the working area of ​​the milling machine, provide a clean working environment for the operator, and reduce the harm of dust to human health;

[0022] A fixing ring 10 is fixedly connected to one side of the inner wall of the dust removal frame 1, and a plurality of support bars 11 are fixedly connected to the inner wall of the fixing ring 10. A bearing 17 is fixedly connected between the plurality of support bars 11, and a rotating rod 12 is fixedly connected inside the bearing 17. The bearing 17 plays a lubricating role, making the rotating rod 12 rotate more smoothly;

[0023] One end of the rotating rod 12 is fixedly connected to the fan blade 13, and the end of the rotating rod 12 away from the fan blade 13 extends into the precision filter cylinder 8, the outer wall of the rotating rod 12 is fixedly connected to the fixing frame 14, and the end face of the fixing frame 14 away from the rotating rod 12 is fixedly connected to the brush strip 15, and the brush strip 15 is tightly fitted with the interior of the precision filter cylinder 8. When the air passes through the dust removal frame 1 and the flowing air passes through the fan blade 13, the fan blade 13 rotates under the blowing of the air, driving the rotating rod 12 to rotate, and then causing the fixing frame 14 to rotate. The brush strip 15 on the fixing frame 14 moves the dust on the inner wall of the precision filter cylinder 8 to prevent dust from being adsorbed on the inner wall of the precision filter cylinder 8 and affecting the ventilation effect, thereby ensuring smooth air circulation and improving the dust removal efficiency.

[0024] Reference Figure 1 The outer wall of the other end of the dust removal frame 1 is fixedly connected with a mounting plate 2, and the mounting plate 2 is installed on the protective cover of the milling machine. The inclined dust removal frame 1 and the precision filter cylinder 8 are convenient for dust deposition.

[0025] Reference Figure 1-Figure 3One end of the dust removal frame 1 is fixedly connected to a connected threaded ring 3, and the outer wall of the threaded ring 3 is connected to the threaded cover 4 through a threaded rotation. The end of the precision filter cylinder 8 away from the sealing ring 9 is fixedly connected to the threaded cover 4, and the center position of the threaded cover 4 is fixedly connected to the insert cylinder 16, and the end of the rotating rod 12 away from the fan blades 13 is inserted into the insert cylinder 16. The insert cylinder 16 serves to limit the rotating rod 12, so that the rotating rod 12 rotates more stably, and the brush strip 15 is always close to the inner wall of the precision filter cylinder 8.

[0026] Reference Figure 1 and Figure 2 The upper outer wall of one end of the dust removal frame 1 is fixedly connected to the connected air outlet frame 5, the interior of the air outlet frame 5 is fixedly connected to a fixing plate 6, the interior of the fixing plate 6 is fixedly connected to an exhaust fan 7, and one end of the precision filter cylinder 8 is fixedly connected to a sealing ring 9, and the sealing ring 9 is precisely fitted with the fixing ring 10. The sealing ring 9 plays a good sealing role, allowing air to smoothly enter the precision filter cylinder 8, thereby improving the comprehensiveness of dust removal.

[0027] Working principle: When in use, install the mounting plate 2 on the dust removal frame 1 onto the protective cover of the milling machine. When the milling machine is working, start the exhaust fan 7 inside the air outlet frame 5. The exhaust fan 7 works to draw the air in the milling machine into the dust removal frame 1. The air passes through the fixing ring 10 and enters the dust removal frame 1. The dust removal frame 1 will filter out the dust in the air. The filtered air passes through the dust removal frame 1 and enters the air outlet frame 5. Finally, the clean air is discharged through the exhaust fan 7. When the air flows, the air will pass through the fan blades 13. The fan blades 13 rotate under the blowing of the air. The rotation of the fan blades 13 will drive the rotating rod 12 in the bearing 17 to rotate. The rotation of the rotating rod 12 drives the fixing frame 14 to rotate. The fixing frame 1 4 rotates, the brush strip 15 on the fixing frame 14 will move the dust on the inner wall of the precision filter cylinder 8 to prevent the dust from being adsorbed on the inner wall of the precision filter cylinder 8 and affecting the ventilation effect. When the dust removal is completed, the exhaust fan 7 is turned off and the threaded cover 4 on the threaded cover 4 is removed by rotation. The movement of the threaded cover 4 drives the precision filter cylinder 8 to move, and the sealing ring 9 on the precision filter cylinder 8 is separated from the fixing ring 10. The rotating rod 12 is separated from the insert cylinder 16, and the precision filter cylinder 8 is taken out from the dust removal frame 1. The staff cleans the dust inside the precision filter cylinder 8, and finally inserts the cleaned precision filter cylinder 8 back into the dust removal frame 1, inserts the rotating rod 12 into the insert cylinder 16, and rotates the threaded cover 4 back to install it on the threaded ring 3.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
