Description

Technical Field

[0001] The utility model relates to the technical field of shield machine excavation auxiliary mechanisms, in particular to a dust collection bin equipped at a shield machine. Background Art

[0002] As we all know, in the process of underground tunnel construction, shield machines are used to excavate underground soil or rock layers, and the excavated mud and sand are sent to the conveyor belt, and then discharged by the conveyor belt. In the process of excavation, although the shield machine will spray water to cool the cutter head and reduce dust, there will still be dust at the discharge port where the stone is discharged to the conveyor belt.

[0003] At present, for the place where the discharge port of the shield machine connects with the conveyor belt, an exhaust fan is generally set up, and then an exhaust pipe is connected to the outside. The exhaust pipe is finally led to the outside, and the dust here is sucked out again by the exhaust fan to the outside, so as to improve the environmental quality of the excavation site. However, relying on the exhaust fan to suck, it is still easy to have the problem of dust leakage. After a long period of excavation, there will still be dust floating in the working space. Some construction workers will install a warehouse here to block the dust from floating out. However, the establishment of the warehouse will cover the mechanism here. When the shield machine is working, it is often necessary to inspect or adjust various mechanisms. The establishment of the warehouse will be an obstacle when the inspection and adjustment are required, and even the warehouse needs to be dismantled. When the inspection is completed, it will be installed again. Therefore, this design will make it very cumbersome for personnel to operate. Utility Model Content

[0020] like Figures 1 to 4 As shown, the present embodiment provides a dust collection bin equipped at a shield machine, comprising a top plate 1, a column 2 and a soft adhesive tape 3. The top plate 1 is made of a magnetic alloy material, the column 2 is connected to the four corners of the top plate 1 and is integrally formed, the bottom of the column 2 is fixedly installed at the discharge port of the shield machine, the soft adhesive tape 3 is a long strip of cuttable soft adhesive to facilitate cutting when necessary, one end of the soft adhesive tape 3 is bent to form a lap joint 31, the lap joint 31 is embedded with a first magnet 32, and the ends of both side surfaces of the soft adhesive tape 3 are embedded with second magnets 33, the soft adhesive tape 3 is adsorbed on the edge of the top plate 1 one by one by relying on the lap joint 31, and the soft adhesive tape 3 is hung side by side on the side of the top plate 1, the soft adhesive tape 3 and the soft adhesive tape 3 are adsorbed to each other through the second magnet 33, and the upper end of the top plate 1 is provided with a avoidance hole 11 for the exhaust pipe to extend out. The bottom of the column 2 is provided with a mounting portion 21, and the mounting portion 21 is a gasket provided with a screw hole, or a buckle that can be fastened to a shield machine component, or a welding sheet used for welding.

[0021] The present embodiment relies on the top plate 1 and the column 2 to form the frame body of the dust collection bin, and sets up soft adhesive tape 3 around the frame body, and relies on the soft adhesive tape 3 to wrap up the whole periphery of the frame body, thus forming a dust collection bin, so that the flying dust at the discharge port of the shield machine can be blocked. At the same time, the soft adhesive tape 3 is set up in parallel one by one, and is installed by magnetic suction, so that when it is necessary to check the internal situation of the dust collection bin, it is not necessary to remove the soft adhesive tape 3, and the soft adhesive tape 3 can be directly pushed aside.

[0022] During specific use, it is only necessary to fix the column 2 to the corresponding position, and then the soft tape 3 is adsorbed one by one on the edge of the top plate 1 by means of the first magnet 32, and then the second magnets 33 on the side and end of the soft tape 3 are attracted to each other, so that the soft tapes 3 are connected again. Without external force, the soft tapes 3 can be connected to each other as a whole. In addition, the material of the column 2 is the same as that of the top plate, so the soft tape 3 at the edge can be adsorbed on the column 2 by means of the second magnet 33. In this way, a dust collection bin can be formed by the overall installation, and it can be installed by the attraction of the magnets, and it can be quickly disassembled when necessary.

[0023] Furthermore, since the avoidance hole 11 is for the exhaust pipe to pass through, in order to make the exhaust pipe tighter after being passed through, the top plate 1 of this embodiment is provided with a soft rubber sleeve 12 at the avoidance hole 11. And in order to use exhaust pipes of different sizes, at least one cutting groove 13 is provided on the soft rubber sleeve 12 of this embodiment, and the cutting groove 13 is in a "V" shape. Therefore, the corresponding cutting grooves can be cut according to the exhaust pipes of different sizes, so as to achieve the appropriate size to install the exhaust pipe, and the establishment of the remaining cutting grooves 13, because they are in a "V" shape, the elasticity is improved, which will improve the close fit of the exhaust pipe.
