Optionally, the mobile dust collection hood according to the present invention further includes a wear-resistant ring, such as a wear-resistant rubber ring 6 , fixedly installed at the other end of the rigid inner sleeve 1 .

3 to 4 show diagrams of the operation process of the wear-resistant rubber ring 6 of the mobile dust collection device according to the present invention. First, the installation structure of the wear-resistant rubber ring 6 will be described with reference to FIG. 3 or FIG. 4 . As shown in Figure 3 and Figure 4, a flange 63 surrounding the outer circumference of the inner sleeve 3 is provided at the rear end of the rigid inner sleeve 3, and the wear-resistant rubber ring 6 is installed on the flange 63, and then, the rubber ring is used to The pressing plate 62 presses the wear-resistant rubber ring 6 , and finally the wear-resistant rubber ring 6 is fixed on the flange 63 by fasteners (such as bolts 61 ).

At this time, the wear-resistant rubber ring 6 plays the role of sealing the rigid inner casing 3 and the rigid outer casing 1. At the same time, the wear-resistant rubber ring 6 also prevents the rigid inner casing 3 from The air at the end is reversely sucked to increase the load of the blower fan in the mobile dust collection hood, and can also prevent the dust in the rigid outer sleeve 1 from being brought back into the rigid inner sleeve 3 . As shown in Figures 3 and 4, when the rigid inner sleeve 3 moves toward the most proximal end of the work, that is, when moving along the retreat direction, the wear-resistant rubber ring 6 is equivalent to a scraper, which will be deposited in the rigid outer sleeve 1 The dust is swept into the dust collector 13, thereby cleaning the inner wall of the rigid outer sleeve 1, and finally reducing the running resistance of the rigid inner sleeve 3 in the rigid outer sleeve 1.

In the mobile vacuum device according to the present invention, the rigid inner sleeve 3 may further include a flexible connector 4, so that the rigid inner sleeve 3 has a certain degree of flexibility. Preferably, the flexible connecting member 4 can be located outside the position where the rigid inner sleeve 1 and the rigid outer sleeve 1 are nested with each other. The rigid inner casing 3 can be cut open by a cutting device, and the two ends of the flexible connecting member 4 are respectively installed on the two ends of the disconnection of the rigid inner casing 3 by fasteners and seals. It is also possible to form the rigid inner sleeve 3 in several parts connected to each other and then provide a flexible connection 4 between two parts. Optionally, the flexible connecting piece 4 may be a bellows.

During operation, when the dust collection hood 10 moves forward or backward, the phenomenon of "rail gnawing" will occur due to the torsion or inclination of the rigid inner and outer sleeves, which is not conducive to the movement of the rigid inner sleeve 3 in the rigid outer sleeve 1 . By installing the flexible connector 4 in the middle of the rigid inner sleeve 3, the inner walls of the rigid inner sleeve 3 and the rigid outer sleeve 1 are prevented from being misaligned following the vacuum hood 10 so that a dead angle cannot be moved, so that the rigid inner sleeve 3 can It can freely expand and contract in the rigid outer sleeve 1, and finally clean the smoke and dust in the production work area. Optionally, the flexible connecting piece 4 may be a bellows.

In addition, in order to prevent the above-mentioned "gnawing rail" phenomenon, a deviation adjuster 5 can also be set on the mobile dust collection hood, and the deviation adjuster 5 is used to adjust the rigid inner sleeve 3 so that the rigid inner sleeve 3 Capable of tilting within a predetermined range. Fig. 5 shows a schematic diagram of the connection relationship between the deviation adjuster 5 and the inner sleeve of the mobile dust collection device according to the present invention. As shown in Figure 5, the deviation adjuster 5 includes: a bracket 51, which is arranged directly below the inner casing 3, and whose bottom end is fixed on the dust collection hood 10; On the top of the bracket 51; two bearing seats 53 are installed in the inner tray by mechanical connection (for example, welding, screw connection, rivet connection, etc.), and each bearing seat 53 is installed with a rigid inner The extension direction of the casing 3 is a vertical shaft; the support wheel 54 is rotatably mounted on the shaft of the bearing seat 53; the outer tray 55 is a tray with an open bottom, and the outer surface of the top of the outer tray 55 is fixed on the outer surface of the outer tray 55. On the underside surface of the rigid inner casing 3, the inner surface of the top of the outer tray 55 is supported by the support wheels 54, wherein, the uppermost end of the inner tray 52 and the inner top surface of the outer tray 55 There is a predetermined distance (for example, 20 mm) between them, and there is a predetermined gap (for example, 30 mm) between the outer peripheral surface of the inner tray 52 and the inner peripheral surface of the outer tray 55 . In this way, when the rigid inner sleeve 3 is biased (for example, tilted), the bias is controlled within a predetermined range due to the above structure. According to the above-mentioned structure of the utility model, since the frictional force of the rolling friction of the supporting wheel 54 is far smaller than the frictional force of its lateral sliding friction, the supporting wheel 54 is conducive to the reciprocating movement of the rigid inner sleeve 3 along the direction of the track 8 . In addition, when the left end of the rigid inner sleeve 3 tilts downward and the right end tilts upward, the lower left end of the outer tray 55 will touch the left outer surface of the inner tray 52, thereby controlling the degree of inclination; similarly, when the left end of the rigid inner sleeve 3 When the upper right end is inclined downward, the lower right end of the outer tray 55 will touch the right outer surface of the inner tray 52, thereby controlling the degree of inclination. Therefore, according to the above-mentioned structure of the deviation adjuster 5, the mobile dust collection hood according to the present invention can effectively prevent the twisting, deflection or inclination of the rigid inner casing 3.

Optionally, at the position where the rigid inner sleeve 3 and the rigid outer sleeve 1 overlap each other, the rigid inner sleeve 3 can be arranged at predetermined intervals along the axial direction of the rigid inner sleeve 3 The supporting ring on the outer circumferential surface of the inner and outer sleeves is used to make the sliding between the rigid inner and outer sleeves smooth and stable.

Although the utility model shows that the dust collection hood 10 is in the shape of a barrel, the shape of the dust suction hood 10 is not limited thereto, and the dust collection hood 10 can also be formed into other shapes as long as it can effectively collect the production work. Just a little bit of smoke.

Although the specific structure of the deviation adjuster 5 is shown in the present utility model, the structure of the deviation adjuster is not limited thereto, and the deviation adjuster can also be formed according to other structures, as long as it can adjust the rigidity of the inner casing. The degree of inclination is sufficient.

The following describes the operation process of the mobile vacuum device according to the present invention with reference to FIGS. 2 to 4 .

As shown in Figures to 4, when the driving device 7 drives the dust collection hood 10 to advance on the track 8 (that is, to move toward the farthest end of the work), the rigid inner sleeve 3 moves inside the rigid outer sleeve 1 to reach the working position. After the position, the soot is collected, so that the collected soot passes through the rigid inner sleeve 3 and the rigid outer sleeve 1 to the dust collector 13 . When the smoke and dust pass through the rigid outer casing 1, the diameter of the rigid outer casing 1 is larger than the diameter of the rigid inner casing 3, so the speed of the smoke and dust slows down, so that natural settlement occurs, and the large particles in the smoke and dust will fall and deposit on the rigid outer casing. 1 on the inner wall. After the operation is completed, the dust collection hood 10 retreats under the drive of the driving device 7 (that is, moves toward the most proximal end of the work). At this time, the hard wear-resistant rubber ring arranged on the rear end of the rigid inner sleeve 6 Remove the dust deposited on the inner wall of the rigid outer casing 1 into the dust collector 13. In addition, the mobile dust collection hood of the present utility model also includes a flexible connector 4 and a deviation adjuster 5. When the rigid inner sleeve 3 twists or tilts during the movement, the rigidity is prevented by the flexible connector 4 and the deviation adjuster 5. The inner wall of the inner casing 3 and the rigid outer casing 1 follows the misalignment of the dust suction hood 10 and cannot move due to a dead angle. Therefore, the rigid inner casing 3 can be freely expanded and contracted in the rigid outer casing 1, thereby effectively cleaning the smoke and dust in the production work area.

According to the rigid mobile dust collection device of the present invention, since the inner and outer casings are made of rigid hard materials, the phenomenon of natural sedimentation and accumulation of dust can be prevented.

In addition, according to the rigid mobile dust collection device of the present invention, since the rear end of the rigid inner sleeve is equipped with a wear-resistant rubber ring to remove the smoke and dust deposited on the inner surface of the rigid outer sleeve, thereby avoiding natural deposition of dust Phenomenon, effectively clean the smoke and dust, while preventing damage to the rigid inner and outer sleeves, thereby prolonging the service life of the rigid inner and outer sleeves.

In addition, by arranging the flexible connecting piece and the deviation adjuster, it is possible to prevent the "rail gnawing" phenomenon that occurs due to the twisting, deflection or inclination of the rigid inner and outer sleeves when the hood moves forward or backward.

Although some embodiments of the present utility model have been shown and described, those skilled in the art should understand that, without departing from the principles and spirit of the utility model whose scope is defined by the claims and their equivalents, these can be modified.
