[0028] The blow pipe assembly 203 in this embodiment includes a blow pipe 204, a blow pipe fixing seat 205 and a blowing nozzle 206. The blow pipe 204 is connected to the connecting rod 201 through a universal coupling 202; the blow pipe 204 is provided with a blow pipe fixing seat 205 which is connected to the thick blowing pipe in the vertical pipe 102 of the blowing and suction cleaner; and a plurality of blowing nozzles 206 are provided on the blow pipe.

[0029] A composite drafting and blowing nozzle steering mechanism comprises a composite mechanical steering mechanism 300 and a drafting and blowing nozzle fixing mechanism 200.

[0030] Among them, the composite mechanical steering mechanism 300 includes: a fixed bracket 103, fixed on the vertical pipe 102 of the blowing and suction cleaner, and a rotatable rotating shaft 104 matching the number of roller couplings 105 is provided on the fixed bracket 103; two roller couplings 105 arranged on the left and right, correspondingly installed on the rotating shafts 104 matching them; a fixed guide rail 101 corresponding to the number and position of the roller couplings 105; and a meshing gear set 301, including a pair of meshing gears 302, and the set of gears 302 is correspondingly installed on the rotating shafts 104 matching them, so that the two roller couplings 105 form a rotating body that can rotate simultaneously.

[0031] In the present embodiment, when any one of the two roller couplings 105 disposed on the left and right sides collides with the fixed guide rail 101 at its corresponding position, the rotating shaft 104 in the roller coupling 105 will be driven to rotate, and through the meshing action of the gear 302 in the gear set 301, the rotating shaft 104 in the other roller coupling 105 will also rotate at the same time, thereby driving the drafting nozzle fixing mechanism 200 connected to the rotating shaft 104 to reverse direction;

The upper end of the connecting rod 201 is connected to the rotating shaft 104, the lower end of the connecting rod 201 is connected to the blow pipe combination 203, and the connecting rods 201 are connected to each other through the universal coupling 202.

[0034] The working principle of the drafting nozzle turning in this embodiment is:

When the roller assembly 105 moves away from the fixed guide rail 101, under the action of the tension spring 108 and the positioning plate 110, the nozzle 206 rotates to the position on the textile machinery that needs to be cleaned.

[0036] When both the front and rear ends of the vehicle need to change direction, a roller combiner 105 is set. During the process of any one of the two roller combiners 105 set on the left and right colliding and contacting with the fixed guide rail 101 at its corresponding position, the rotating shaft 104 in the roller combiner 105 will be driven to rotate. Through the meshing action of the gear set 301, the rotating shaft 104 in the other roller combiner 105 will also rotate at the same time. The working principle of the stretching nozzle fixing mechanism is the same as above.
