the utility model provides a special puller for a drum bearing of a threshing and redrying air-separating machine, which comprises a bearing beam 1, a worm gear mechanism 2, a top-pull lead screw anti-rotation sleeve 3, a top-pull lead screw 4 and a pull claw 5; bearing beam 1 one side install worm gear mechanism 2 through fixing bolt 6, worm gear mechanism 2 worm both ends are established worm gear mechanism drive hexagonal head 7, 1 opposite side fixed mounting of bearing beam has a top to pull lead screw anti-rotating sleeve 3, its center is relative with worm gear mechanism 2 worm wheel centers, top to pull lead screw 4 pierces through bearing beam 1, the worm wheel center of worm gear mechanism 2 is passed to one end, the other end nestification is in top to pull lead screw anti-rotating sleeve 3, waist type groove is opened to top to pull lead screw anti-rotating sleeve 3 side, fixed mounting has stop screw 8 on the groove, with top to pull lead screw 4 screw-thread fit, draw 5 symmetrical both sides that are located worm gear mechanism 2 of claw, through nut fixed mounting on bearing beam 1.

Preferably, a retainer 9 is installed between the pulling claws 5, both ends of the retainer 9 are fixed on the pulling claws 5 through butterfly nuts 10, and the middle part is in a semi-circular arc shape.

The utility model has the advantages that:

the utility model discloses utilized worm gear mechanism turbine and worm for crossing 90 degrees, the drive position can be in the characteristics of side, the utilization is rotated six square heads of worm gear mechanism drive and is driven worm gear mechanism, then utilize the turbine to drive the screw rod motion of pulling up with it complex, it prevents rotating sleeve and lock screw to pull up the screw rod and guarantees that the screw rod of pulling up makes linear motion to pull up the screw rod, the dismantlement process that makes whole area seat bearing becomes convenient, swift, very big reduction operating personnel's intensity of labour, and is simple and convenient, and time and labor are saved.
