Detailed Description

The invention will be further described and illustrated with reference to the accompanying drawings.

As shown in fig. 1 to 5, embodiment 1 discloses a rope exploration drilling machine rotation box, which includes a gear box 14, a bull gear shaft 12 is disposed in the gear box 14, pinions 20 are respectively disposed on the gear boxes 14 on two sides of the bull gear shaft 12, the pinions 20 are respectively engaged with a bull gear 11 on the bull gear shaft 12, the bull gear shaft 12 is a stepped shaft and is lengthened in length, bearings i, bearings ii and oil seals are respectively disposed on two sides of the bull gear shaft 12 in sequence and symmetrically, an air seal 6 and a packing 3 are further sequentially disposed on one side of the bull gear shaft 12, and the bull gear shaft 12 is a hollow shaft.
