The grid air duct 3 is also connected with a movable dust collection vehicle 5 in a sliding mode, the side face of the movable dust collection vehicle 5 is connected with the portal frame 2, and the portal frame 2 can drive the movable dust collection vehicle 5 to move on the top of the grid air duct 3.

The belt 4 penetrates through the movable dust collection vehicle 5, fork-shaped parts 6 for guiding are fixedly welded at two ends of the movable dust collection vehicle 5, the number of the fork-shaped parts 6 is four, two of the fork-shaped parts are symmetrically welded at the front end of the movable dust collection vehicle 5, the other two fork-shaped parts are symmetrically welded at the rear end of the movable dust collection vehicle 5, and guide rollers 7 are rotatably connected to the inner sides of the fork-shaped parts 6.

An upper fixed shaft 8 and a lower fixed shaft 9 are connected inside the movable vacuum sweeper 5, wherein the number of the upper fixed shaft 8 and the number of the lower fixed shaft 9 are two, one of the upper fixed shaft 8 and the lower fixed shaft 9 is arranged at the front end of the movable vacuum sweeper 5, and the other one of the upper fixed shaft 8 and the lower fixed shaft 9 is arranged at the rear end of the movable vacuum sweeper 5.

Two ends of the upper fixing shaft 8 and the lower fixing shaft 9 penetrate through the inner wall of the movable vacuum sweeper 5, two ends of the upper fixing shaft 8 and the lower fixing shaft 9 are respectively provided with a fixing disc 10, the fixing disc 10 is composed of two parts, one part of the fixing disc is arranged on the outer side wall of the movable vacuum sweeper 5, the other part of the fixing disc is arranged on the inner side wall of the movable vacuum sweeper 5, and the two parts of the fixing disc 10 are fixedly connected through screws, namely the fixing disc 10 on the inner side and the outer side of the movable vacuum sweeper 5 is fixed through the screws.

The upper fixing shaft 8 and the lower fixing shaft 9 are rotatably connected with guide resetting components which are used for supporting and correcting the belt 4.

When the dust collection vehicle is used, the belt 4 firstly passes through the fork-shaped parts 6 at the rear end of the movable dust collection vehicle 5, the side edges of the belt 4 penetrate through the two fork-shaped parts 6, the guide roller 7 is driven to rotate when the side edges of the belt 4 are in contact with the guide roller 7, rolling friction exists between the belt 4 and the guide roller 7, then the belt 4 penetrates through the upper fixing shaft 8 and the lower fixing shaft 9, and finally the belt passes through the fork-shaped parts 6 at the front end of the movable dust collection vehicle 5.

Referring to fig. 5 and 7, as a preferred embodiment of the present invention, the guiding and returning assembly includes a roller 12, a rotating disc 13, a spring 15 and a chuck 16, wherein the roller 12 is rotatably connected to the outer sides of the upper fixed shaft 8 and the lower fixed shaft 9, a plane bearing is disposed between the roller 12 and the upper fixed shaft 8, and between the roller 12 and the lower fixed shaft 9, the rotating disc 13 is fixed on the roller 12 by welding, a limiting groove 14 is formed on the inner side of the rotating disc 13, the chuck 16 is clamped in the limiting groove 14, the chuck 16 can move in the rotating disc 13 along the limiting groove 14, and the spring 15 is disposed between the chuck 16 and the rotating disc 13.

Limiting rings 11 are welded and fixed on the upper fixing shaft 8 and the lower fixing shaft 9, and the limiting rings 11 are positioned on the outer side of the rotating disc 13.

The working process and principle are as follows: during the use, because the area cutting article are great, it removes to need portal frame 2 to drive cutting equipment, article on cutting platform 1 are cut, portal frame 2 drives simultaneously and removes dirty-suction vehicle 5 and removes on grid wind channel 3, remove dirty-suction vehicle 5 and pass through Y-piece 6 and last fixed axle 8 and lower fixed axle 9 and jack up belt 4, the convenient sweeps dust that will cut on the platform 1 is collected, then carry away the expense bits through grid wind channel 3, and the belt 4 that is not jack-up by removing dirty-suction vehicle 5 is adsorbed on grid wind channel 3 by the negative pressure in the grid wind channel 3.

When the belt 4 passes through the fork-shaped parts 6 at the front end of the movable dust collection vehicle 5, firstly, the fork-shaped parts 6 at two sides limit the belt 4, so that the belt 4 is prevented from moving left and right, meanwhile, when the side edge of the belt 4 contacts the guide roller 7, the guide roller 7 can be driven to rotate, sliding friction is changed into rolling friction, friction force borne by the side edge of the belt 4 is greatly reduced, friction loss is reduced, when the belt 4 passes through the space between the upper fixing shaft 8 and the lower fixing shaft 9, similarly, the belt 4 contacts the roller 12, the roller 12 can rotate around the lower fixing shaft 9, sliding friction is changed into rolling friction, and friction loss of the belt 4 is reduced.

And the belt 4 is blocked by the chucks 16 on both sides, when the belt 4 shifts, when moving to one side, the chucks 16 are pushed to move outwards, the compression springs 15 are compressed, the side edges of the belt 4 push the chucks 16 to compress the springs 15, on one hand, the phenomenon that the belt 4 is seriously worn due to overlarge pressure between the belt 4 and the chucks 16 when the belt 4 shifts can be avoided, and on the other hand, the belt 4 can be pushed to return to the initial position through the restoring force action of the springs 15.

Belt 4 is when the Y-piece 6 through removing the 5 rear ends of dirty-suction vehicle, and is same, Y-piece 6 is injectd belt 4, has avoided belt 4 to remove about for belt 4 still can resume initial position leaving behind removing dirty-suction vehicle 5, avoids belt 4 dislocation, leads to grid wind channel 3 top breach to appear, can't keep the negative pressure state.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
