[0003] The cement plant uses manual labor and loading machines to load bagged cement. During the loading process, the loader moves along the direction of the vehicle and the height of the cement to ensure uniform loading of the cement. A large amount of dust will be generated during the loading process. The original dust collection duct and dust collection hood are fixed in a designated position and cannot be adjusted left and right or up and down.

[0004] However, the above-mentioned publicly disclosed solutions have the following shortcomings: the length of the dust collecting duct coming out of the dust collector is fixed, the dust collecting hood is welded to the head height of the loader and the relative height of the loader is fixed, the length and size of the dust collecting duct and the dust collecting hood limit the moving range and dust collecting effect of the loader, and the dust collecting hood is too heavy, which may cause deformation and damage to the loader after long-term use. Utility Model Content

[0009] Furthermore, a loader is fixedly connected to the lifting and moving unit; and a moving trolley is fixedly connected to the lower end of the loader.

[0010] Furthermore, the lifting and moving unit includes a lifting winch, a pulley block, and a steel wire rope; one end of the steel wire rope is fixedly connected to the lifting winch, and the other end is fixedly connected to the dust collecting hood; the lifting winch is fixedly connected to the loader; and a pulley block is sleeved on the steel wire rope.

[0011] Furthermore, a plurality of movable pipe supports are fixedly connected to the ground at intervals at the lower end of the socket movable air duct; and thrust baffles are fixedly connected to the ground corresponding to the fixed air duct and the socket movable air duct.

[0012] Furthermore, a plurality of fixed pipe brackets are fixedly connected to the ground at the lower end of the fixed air duct; a plurality of fixed clamps are fixedly connected to the fixed pipe brackets; and the fixed clamps are sleeved on the fixed air duct.

[0013] The utility model provides a mobile dust collecting device with the following beneficial effects:

[0014] 1. The utility model generates negative pressure through the operation of the stack dust collector. The negative pressure enters the lifting dust collection unit through the fixed air duct and the socket-type movable air duct and comes into contact with the atmosphere again. Then, the height of the lifting dust collection unit and the insertion overlap depth between the fixed air duct and the socket-type movable air duct can be adjusted, so that the lifting dust collection unit can be adjusted to the surface of the transport vehicle for close dust collection, thereby greatly improving the dust collection efficiency and being adaptable to transport vehicles of different sizes. This solves the problem that existing fixed dust collection devices cannot adapt to vehicles of different sizes for efficient dust collection.

[0015] 2. The utility model can pull the dust collecting hood up and down to change the dust collection height through the lifting and moving unit, and then the telescopic tube itself deforms to adapt to the change of the upper and lower heights, which can be adapted to transport vehicles of different sizes, so that the air flow channel for dust collection is connected, and the dust raised when the cement is loaded can be absorbed by the platform dust collector, thereby preventing the spread and harm. At the same time, it can be adapted to transport vehicles of different sizes, and the upper and lower heights can be adjusted according to the height of the vehicle and the height of the cement bag, so that dust collection can be carried out at a close distance, thereby greatly improving the dust collection efficiency and adaptability. At the same time, the dust collecting hood is flexibly connected to the loader and the mobile trolley, and there is a gap between the loader and the loader, which avoids deformation of the loader and affects the service life of the loader. At the same time, the separate lifting dust collecting unit and the loader are more convenient for maintenance. At the same time, the efficient dust collecting unit can reduce environmental risks and reduce the labor intensity of on-site workers and maintenance personnel. The close-range dust collection can greatly improve the utilization of the dust collection negative pressure wind, making useless consumption less and more energy-saving, and solving the problem that the existing fixed dust collection device cannot adapt to different vehicle sizes.
