The invention discloses a special automobile rubber grinding machine for a rubber covered roller. The special automobile rubber grinding machine comprises a lathe head and a lathe bed which are sequentially connected, wherein the lathe head is provided with a headstock, the lathe bed is provided with a tailstock, and a workpiece is fixed between the headstock and the tailstock; the lathe bed below the workpiece is provided with a large planker, a sliding block and a gear are arranged on the large planker, the lathe bed is provided with a linear guide rail and a rack, the sliding block is matched with the linear guide rail, and the gear is matched with the rack; the large planker is provided with a premedial planker and a postmedial planker which can move on the large planker, the premedial planker is provided with a knife rest, and the postmedial planker is provided with a belt sanding machine. According to the special automobile rubber grinding machine, the firmness between a bonding agent and a central spindle can be guaranteed, a traditional sand blasting technology can be replaced, and the surface is not needed to be washed by any solvent, so that the balance of the central spindle can not be damaged, the production efficiency can be improved, the cost is reduced and the labor force is saved, and the key is that the bonding between the rubber and the central spindle can be reliably guaranteed. According to the special automobile rubber grinding machine, the consumable materials can be saved and the environment pollution can be reduced.

The invention discloses a wind driven generator end cover broken bolt dismounting device. A bearing is arranged in the center of a chassis; a rotating shaft rotates around the periphery of the chassis, and fits a bearing; a connecting end fitting a dismounting component is arranged at one end of the rotating shaft; the dismounting component comprises a drilling component for drilling a blind hole in a broken bolt, a tapping component for tapping the blind hole as a thread hole, and a screw rod component fitting the thread hole; the screw rod component comprises a screw rod; and the thread rotating direction of the screw rod is opposite to the thread rotating direction of the broken bolt. The dismounting device has the following beneficial effects: the broken bolt is drilled through the drilling component; then, the drilled hole is tapped; the screw rod component is connected with the tapped thread hole; and as the thread rotating direction of the screw rod is opposite to the thread rotating direction of the broken bolt, the broken bolt can be taken out through reversely rotating the rotating shaft, the operation is convenient and fast, the damage of a traditional thread and the dismounting of an outer end cover are not needed, the repair efficiency is greatly improved, and the repair cost is reduced.

The invention provides an automatic knife sharpening device for a silage harvester, which is characterized in that it includes a reciprocating mechanism and a knife sharpening feeding mechanism; wherein the reciprocating mechanism includes a guide rail base, two guide rails horizontally installed on the guide rail base, A pair of sliders installed on the two guide rails, a slider plate that fixes the pair of sliders together, a lead screw, a lead screw support, a lead screw nut, a motor and a pawl; the sharpening mechanism includes a grinding Knife housing, knife grinding wheel, worm wheel, worm, shaft, feed sleeve, ratchet wheel; knife grinding feeding mechanism is connected with the slider plate of the reciprocating mechanism through the knife grinding housing. Before grinding the knife, adjust the grinding wheel to be in contact with the moving knife of the hob-type chopper. When grinding the knife, the grinding wheel is driven by the motor to reciprocate by the screw nut, thereby resetting the cutting edge of the moving knife on the drum. sharpen. The structural design is simple and practical, reduces manufacturing difficulty and cost, is easy to operate and control, and improves work efficiency and work quality.
