Hydrogeological drilling-type detection equipment includes a detection support frame, where the detection support frame is fixedly connected with a detection box body with a through hole, the through hole is communicated with an inside of the detection box body, a drilling box body is arranged inside the through hole, a lifting assembly is arranged inside the detection box body, the drilling box body is slidably connected with the through hole through the lifting assembly, a bottom end of the drilling box body is provided with a multifunctional drilling assembly provided with a blocking assembly, each of four corners of a bottom end of the detection support frame is provided with a moving wheel, the detection support frame is provided with a stable support assembly, the stable support assembly is correspondingly arranged with the moving wheel, and one side of the detection support frame is fixedly connected with an armrest.

A working machine includes a machine body, a working device including a function portion to perform a function while in contact with a work target object, a hydraulic actuator to switch between a state in which the function portion contacts the work target object and a state in which the function portion is not in contact with the work target object, a manual operator to be operated in relation to actuation of the hydraulic actuator, and a controller configured or programmed to control the actuation of the hydraulic actuator. The controller is configured or programmed to derive a degree of contact of the function portion with the work target object based on a pressure of hydraulic fluid supplied to the hydraulic actuator, and if the derived degree matches or substantially matches a preset optimal degree, change an actuation state of the hydraulic actuator in action.

A drill stand includes a base supportable upon a mounting surface, a mast defining a longitudinal axis and extending upward from the base, a carriage moveably coupled to the mast and configured to support a core drill thereon, a spindle assembly for moveably adjusting the carriage along the mast, a handle assembly for rotating the spindle assembly, and a lock assembly that is operable to secure the carriage in a selected position on the mast. The lock assembly includes a first adjustment dial positioned on a first side of the carriage, a second adjustment dial positioned on a second side of the carriage, and a locking member operably coupled to the first and second adjustment dials to selectively secure the carriage on the mast.

A system includes a utility chassis for use with rock drills for automatic and safe drilling of target surfaces. The system includes a remote control unit that is pneumatically coupled to the system and may be selectively detached from the utility chassis so that the operator may control the system via the remote control unit from afar. The utility chassis has a lightweight vertical frame member with an off-set wheel base that allows the system to maintain its balance and maintain engagement with the ground when while being operated remotely and without being manually supported.

A conductor of the extendable conductor assembly may be extended (e.g., into a thermal target, such as a preexisting or a newly created feature of a planetary body) and used to thermally couple a rover, vehicle, fixed installation, or other hardware with the thermal target. Thus, the temperature of the hardware may be managed via heat transfer to/from the thermal target. For instance, heat may be transferred from the thermal target to maintain the temperature of the hardware under cold conditions, while excess heat may be transferred to the thermal target under hot conditions. A rover forms a borehole in the lunar surface, in which a conductor is extended to facilitate heat transfer between the rover and the Moon accordingly.

A mobile coring apparatus includes a machine frame including a mount, a mast pivotally connected to the mount and a coring assembly coupled to the mast. The coring assembly is configured to drive a core bit for coring through a surface. The pivotable mast allows for the core bit to remain perpendicular with the horizon when the mobile coring apparatus is used on an angled surface.

An apparatus for drilling a hole in a golf green. The apparatus includes a support frame, a moveable cutter head, a handle, a base, a tread plate, an ejection mechanism, a drive motor configured to power the operation of the apparatus and control device. A drive shaft connects the drive motor with the cutter head via a threaded coupling. The cutter head is advanced relative to the tread plate when the drive shaft is rotated in one rotational direction and is retracted relative to the tread plate when the drive shaft is rotated in the opposite rotational direction. The drive shaft is provided with a central threaded portion and a non-threaded end portion at each end of the thread. The non-threaded end portions act as slip couplings configured to allow a rotation of the drive shaft without axial movement of the threaded coupling to stop the cutter head.
