This invention discloses a magnetically coupled, high-pressure resistant rotary switch, belonging to the technical field of material level detection equipment. Specifically, it comprises a housing cover, a housing, a connecting thread, a drive shaft, a magnet assembly, bearings, a dustproof oil seal, an output shaft, a purge hole, and a wiring inlet. The housing cover is sealed to the top of the housing, forming a sealed, pressure-resistant inner cavity. The drive shaft is vertically mounted inside the housing cavity, and multiple sets of bearings are fixedly fitted around its outer circumference, supporting the drive shaft. The connecting thread is fixedly connected to the bottom of the housing. This invention, by employing a non-contact magnetic coupling transmission structure, eliminates the through-type dynamic sealing structure of traditional rotary switches, fundamentally solving the problem of media leakage under high-pressure conditions. The overall structure is rationally designed, easy to install and maintain, and adaptable to the material level detection needs of various industrial scenarios, possessing good practicality and promotional value.

The utility model provides an automatic agricultural machinery matched weeding machine which comprises a main machine shell, auxiliary machine shells are hinged to the two sides of the main machine shell through hinge shafts, a first protective cover is fixedly installed at the top end of the main machine shell, a connecting frame is installed at the top end of the first protective cover, hydraulic cylinders are hinged to the two sides of the connecting frame, and hinge bases are fixedly installed at the top ends of the two auxiliary machine shells. The output ends of the two sets of hydraulic cylinders are hinged to the corresponding hinge bases. The bottom sides of the two sets of auxiliary machine shells are connected with first weeding knives, and the bottom side of the main machine shell is connected with second weeding knives. The hydraulic cylinder is arranged to drive the auxiliary machine shell to be unfolded or folded around the hinged shaft, the coverage range of the first weeding cutter and the second weeding cutter can be adjusted, meanwhile, when not used, the weeding machine can be folded and stored, and the use flexibility of the device is improved; through the arrangement of the universal wheels, under the cooperation of the sleeve, the supporting rod, the plum blossom handle bolt, the worm, the worm gear and the driving motor, the height of the blade on the weeding machine can be adjusted according to weeds of different heights or the fluctuation of the ground.
