[0032] When the pipeline is assisted to remove dust by using the mechanism, the mechanism is placed in the telescopic corrugated pipeline, the advancing roller 30 is abutted against the inner wall of the telescopic corrugated pipeline to support the air knife 10 and drive the air knife 10 to advance along the telescopic corrugated pipeline, the air outlet end of the air chamber 11 and the tapered groove 12 are connected to the negative pressure dust removal machine connected to the telescopic corrugated pipeline, the external gas source is connected to the air inlet end of the air chamber 11, the external gas source can be selected from existing equipment such as an air compressor, the position of the air adjusting piece 20 is adjusted, the opening of the air outlet end of the air chamber 11 is changed to adapt to actual requirements, then the external gas source is started, the gas flows along the inner wall of the air chamber 11 and the tapered groove 12, is obliquely blown to the groove of the telescopic corrugated pipeline, disturbs the dust in the groove, and the dust is dispersed from the groove, then the negative pressure dust removal machine is started, and the flying dust can be easily sucked away.

[0033] By using the pipeline auxiliary dust removal mechanism provided in the application, the dust accumulated in the groove of the telescopic corrugated pipeline can be disturbed and dispersed, the dust is easily sucked away by the negative pressure dust removal machine, the damage of the pipeline caused by artificial knocking and vibration of the outer wall of the pipeline is avoided, and the dust removal efficiency and effect are improved.

[0034] In the embodiment, the air adjusting piece 20 comprises a rotating handle 21, a tapered block 22 and a threaded rod 23 connected in sequence, the rotating handle 21 is located outside the air knife 10 and is used for rotating to adjust the position of the air adjusting piece 20, the tapered block 22 is matched with the shape of the tapered groove 12, a communication groove 13 and an adjusting groove 14 are sequentially arranged on the air knife 10 near the narrow end of the tapered groove 12, the inner wall of the adjusting groove 14 is provided with threads, the threaded rod 23 is screwed into the adjusting groove 14 after penetrating through the communication groove 13, the communication groove 13 is communicated with the air outlet end of the air chamber 11, and the inner diameter of the communication groove 13 is greater than the inner diameter of the threaded rod 23, the gas introduced by the external gas source can pass through the air outlet end of the air chamber 11, the communication groove 13 and the tapered groove 12 to blow to the outside of the air knife 10, the threaded rod 23 is rotated to adjust the volume of the tapered block 22 inserted into the tapered groove 12, then the distance between the side wall of the tapered block 22 and the side wall of the tapered groove 12 is adjusted, the air blowing amount and the air blowing rate are changed, and different dust removal requirements are adapted.

[0035] Since the expansion state of the telescopic corrugated pipe is different under different working conditions, the angle and depth of the groove part are also different. In the conventional working condition, the vertical inclination angle of the groove side wall is 45°-60°, so the taper angle of the tapered groove 12 in the embodiment can be set to 60°-90°, that is, the inclination angle of the inner wall thereof relative to the axis is 30°-45°, and the air knife 10 is a horizontally placed column, which can exactly adapt to the above-mentioned angle of the groove dust removal requirement. In addition, by adjusting the gas supply speed of the external gas source and the position of the air adjusting piece 20, the flow direction of the gas output by the air chamber 11 can be changed, so that part of the gas is output obliquely outward along the inner wall of the tapered groove 12, and the other part of the gas impacts the side wall of the air adjusting piece 20 and is redirected to be output outward in a direction perpendicular to the axis of the air knife 10 under the blockage of the side wall of the air adjusting piece 20, which directly impacts the deepest part of the groove to avoid the generation of a dust removal dead angle and to achieve high-efficiency dust removal.

[0036] Since the expansion state of the telescopic corrugated pipe is different under different working conditions, the inner diameter is also different, and the telescopic corrugated pipe is easy to be deformed under pressure. If the axial size of the air knife 10 and the travel roller 30 is set to a fixed size, it is difficult to adapt to the requirements of various working conditions, which greatly hinders the travel of the mechanism. Therefore, the roller seat 50 is arranged on the outer side of the air knife 10, the roller seat 50 is connected with the air knife 10 through the telescopic piece 60, the travel roller 30 is rotationally arranged on the roller seat 50, and the telescopic piece 60 can be telescopically extended along the radial direction of the air knife 10. By the telescopic extension of the telescopic piece 60, the distance between the travel roller 30 and the air knife 10 is controlled, and the radial size of the combination of the two is adjusted to adapt to the requirements of different working conditions.

[0037] Referring to the accompanying drawings Fig. 2 The telescopic piece 60 includes a slide rod 61 and an elastic piece 62, which are located on the same side of the roller seat 50. The slide rod 61 extends along the radial direction of the air knife 10 and is slidably connected with the roller seat 50 at the end thereof away from the air knife 10. The slide rod 61 mainly plays a guiding role. When the elastic piece 62 is forced to be telescopically extended, the roller seat 50 can move along the radial direction of the air knife 10, thereby changing the distance between the travel roller 30 and the outer wall of the air knife 10. To avoid the slide rod 61 from sliding off the roller seat 50 and to facilitate installation, a bolt extending along the radial direction of the air knife 10 can be installed on the roller seat 50. The rod part of the bolt serves as the slide rod 61, the cap part abuts against the end face of the roller seat 50 close to the travel roller 30, one end of the rod part of the bolt away from the cap part is threadedly fastened with the air knife 10, and the other end close to the cap part is slidably arranged in the roller seat 50.

[0038] The above-mentioned elastic piece 62 can be a compression spring. The number of the elastic piece 62 and the slide rod 61 can be the same or different. At least part of the elastic piece 62 is sleeved on the slide rod 61 to improve the accuracy of the moving direction of the roller seat 50.

[0039] Generally, the telescopic corrugated pipe is 5-10m long, but the telescopic corrugated pipe is easy to deform, if the advancing roller 30 is electrically driven, the advancing roller 30 will be unevenly stressed due to the random deformation of the telescopic corrugated pipe, causing unstable and unsmooth advancing, therefore, the detachable advancing rod 70 can be arranged on the air knife 10, the advancing rod 70 is located at the end of the air knife 10 away from the air adjusting member 20, the advancing rod 70 is manually pushed to move the air knife 10 inside the telescopic corrugated pipe, so as to gradually disturb the dust in the grooves everywhere, improving the dust removal efficiency and effect.

[0040] Compared with the prior art, the pipeline auxiliary dust removal mechanism and the use method thereof can realize dead angle-free dust removal in the telescopic corrugated pipe, can flexibly adjust the air volume, air speed and external contour size, is suitable for different dust removal working conditions, greatly improves the dust removal efficiency and cleanliness, and reduces the labor intensity of manual dust removal.

[0041] The above is the preferred embodiment of the utility model, it should be pointed out that, for ordinary skilled person in the art, without departing from the principle of the utility model, a number of improvements and refinements can be made, these improvements and refinements should also be considered as the protection scope of the utility model.
