Description

Technical Field

[0001] The utility model relates to a dust waste collection device, in particular to a dust waste collection device for a surface grinder. Background Technique

[0002] A surface grinder is a type of grinding machine that mainly uses a grinding wheel to rotate and grind workpieces to achieve the required flatness. It can be divided into two types according to the shape of the worktable: rectangular worktable and circular worktable.

[0003] When the surface grinder grinds the workpiece, powder waste will be generated on the top of the surface grinder. For the generated powder waste, generally, workers use tools such as brushes and scrapers to clean and collect the powder waste, or use an electric hair dryer to blow away the powder waste. When cleaning the powder waste in these ways, the powder waste will fly into the air and is easily inhaled by the human body. Long-term inhalation of powder waste may cause diseases such as pneumoconiosis, and the flying of powder waste will reduce the quality of the workshop working environment.

[0004] Therefore, a dust waste collection device for a surface grinder that can avoid the flying of powder waste during the collection process is needed. Content of the Utility Model

Specific embodiments

[0023] The present utility model will be further described below in conjunction with the attached drawings and specific embodiments.

[0024] Embodiment 1: A dust waste collection device for a surface grinder, as Figures 1-6 shown, includes a workbench 1, a first pulley 2, an outer shell 3, a main housing 4, a fixing rod 5, a medium-pressure blower 6, a rear fan cover 7, a resistance filter screen 8, a collection cylinder 9, a transparent round cover 10, a pulling block 11, a material blocking cover 12, and a material suction pipe 13. On the upper top of the right side of the workbench 1, the first pulleys 2 are symmetrically slidably arranged front and rear. An outer shell 3 is rotatably arranged between the two first pulleys 2. A main housing 4 is fixedly arranged in the upper middle part of the outer shell 3. A plurality of fixing rods 5 are welded on the inner wall of the main housing 4. A medium-pressure blower 6 is fixedly connected between the plurality of fixing rods 5. A rear fan cover 7 is welded on the upper inner wall of the main housing 4. The rear fan cover 7 is located above the medium-pressure blower 6. A resistance filter screen 8 is fixedly connected to the lower inner wall of the main housing 4. The resistance filter screen 8 is located below the medium-pressure blower 6. A collection cylinder 9 is slidably connected to the middle lower part of the outer shell 3. The upper top of the collection cylinder 9 is communicated with the bottom of the main housing 4. The right side wall of the collection cylinder 9 is connected and communicated with a material suction pipe 13, and the material suction pipe 13 passes through the right side wall of the outer shell 3. A transparent round cover 10 is fixedly connected to the rear side of the collection cylinder 9. A pulling block 11 is fixedly connected to the upper part of the front side of the collection cylinder 9. A material blocking cover 12 is slidably connected to the lower part of the front side of the collection cylinder 9.

[0025] As Figure 2 shown, it further includes a baffle plate 14. The top of the baffle plate 14 is communicated with the bottom of the material suction pipe 13.

[0026] First, the staff places the device on the upper right of the surface grinder through the handle 20, and then starts the medium-pressure blower 6 to make it work. When the medium-pressure blower 6 is running, the blades on the medium-pressure blower 6 rotate at high speed, forming an air negative pressure in the sealed main housing 4, that is, a negative pressure state. This negative pressure state forms a pressure difference with the external atmospheric pressure, thus generating a strong suction force. At this time, the strong suction force first passes through the collection cylinder 9, and then through the suction pipe 13 communicated with the collection cylinder 9 to generate a strong suction force on the bottom of the pipe. The strong suction force absorbs the powder waste on the top of the surface grinder. The powder waste is sucked into the collection cylinder 9 from bottom to top through the suction pipe 13. At the same time, the baffle 14 blocks the powder waste, so that the powder waste will not fly to the right when being absorbed. Under the action of the filter screen 8, the dust waste collected in the collection cylinder 9 will not fly into the main housing 4 too much; at the same time, in order to maintain a certain air pressure and make the air outlet system of the medium-pressure blower 6 operate normally, it is necessary to discharge the air inhaled into the main housing 4. The inhaled air is discharged through the air outlet pipe 15 at the top of the main housing 4. The discharged air is sent to the air outlet plate 17 inside the material baffle frame 16 through the air outlet pipe 15. Because a number of round holes are provided on the air outlet plate 17, the air blowing force is sent from top to bottom. Under the block of the left side wall of the material baffle frame 16, the sent air blowing force blows the powder waste on the top of the surface grinder to the right. The powder waste blown to the right is sucked into the collection cylinder 9 through the suction pipe 13, forming an absorption cycle.

[0027] As Figure 5 and Figure 6 shown, it also includes an air outlet pipe 15, a material baffle frame 16 and an air outlet plate 17. An air outlet pipe 15 is provided at the top of the main housing 4. A material baffle frame 16 is welded to the lower part of the air outlet pipe 15. An air outlet plate 17 is welded inside the material baffle frame 16. A number of round holes are provided on the air outlet plate 17. The left and right frame walls of the material baffle frame 16 are asymmetric, that is, the left and right side walls of the material baffle frame 16 are in the shape of lower on the left and higher on the right, and the air outlet plate 17 is arranged in an inclined state.

[0028] As Figure 2 and Figure 7 shown, it also includes a fixed column 18 and a second pulley 19. A fixed column 18 is fixedly connected to the lower right bottom of the outer shell 3. A second pulley 19 is rotatably connected to the lower part of the fixed column 18.

[0029] As Figure 1 and Figure 2 shown, it also includes a handle 20. The handle 20 is fixedly connected to the outer walls on the front and back sides of the outer shell 3.

[0030] If it is necessary to collect the dust waste on the upper top surface in the middle and on the left side of the surface grinder, the staff applies a leftward thrust to the device. Under the action of the first pulley 2 and the second pulley 19, the staff can easily push the device from left to right to absorb the powder waste. By repeating the left-right advancement in this way, all the powder waste on the upper top surface of the surface grinder can be collected. After the device has worked for a period of time, the staff can observe the loading situation of the powder waste through the transparent round cover 10 at the rear of the collection cylinder 9. When the dust waste is about to fill the collection cylinder 9, the staff only needs to pull the pull block 11 forward to pull out the collection cylinder 9 and the baffle 12 from back to front. Then, pull the baffle 12 downward so that it no longer blocks the discharge port of the collection cylinder 9. Then, pour out the dust waste in the collection cylinder 9. Finally, put the collection cylinder 9 back to its original position. When the device is not needed, the device can be removed by lifting the handle 20 on the device, or the device can be pushed to the edge of the surface grinder when it does not affect the operation of the surface grinder.

[0031] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
