摘要： A device for coupling to a working end of a hydrovac boom hose is disclosed. The device includes a tubular suction tube configured for removably coupling to the working end of the hydrovac boom hose such that an opening of the working end remains unobstructed. A plurality of high pressure rotating turbo nozzles are located around a circumference of the tubular suction tube such that the rotating turbo nozzles surround the working end of the hydrovac boom hose to dislodge earthly materials under the device. The high pressure rotating turbo nozzles are configured for emitting high pressure water that dislodge earthly material. An outer housing to enclose and protect the tubular suction tube, rotating turbo nozzles, and onboard locating device, and to provide an air duct for ambient air to pass down threw. A plurality of air vents in the outer housing that provide flow of ambient air to an area being excavated. The conduit coupled with the outer housing, the conduit for allowing ingress of water to the plurality of high pressure rotating turbo nozzles.

摘要： An excavator is provided, including a body; a leader supported by the body; a head sliding along the leader; a first rod assembled with the head to elevate or rotate by the head; a rod clamp installed at a front end of the leader and clamping a second rod inserted into the ground; and a position fixture sliding along the leader by means of the head and fixing the position of the first rod when assembling the first rod and the second rod. Since the excavator according to the present invention allows an additional rod to be assembled with the rod clamped by the rod clamp due to the position fixture without causing vibration, the assembling work of additional rods can be easily performed.

摘要： A ditch digger having a horizontal cutting disc with spaced and angled replaceable cutting blades housed within a circular frame and surrounded in one semicircle by a dirt blocking chain barrier and by a solid guard barrier in the other semicircle. The digger is attached to a farm tractor via a 3 point hitch and includes a power takeoff connection. The forward portion of the digger's superstructure has a pair of collapsible stands which support the digger with the rear end wheel during storage. The wheel is provided with a height adjustment device for the ditch digger and maintains the position of the ditch digger in the ditch being dug.

摘要： A slitting cutter with at least one drive unit which, by a cutting wheel gear, drives the driven shaft of the cutting wheels equipped with cutting teeth. Although optionally hitherto a clutch has been provided between the driving unit and the actual cutting wheel gear, abrupt blocking of jamming processes on the cutting teeth seriously stressed the cutting wheel gear. This is now inventively prevented in that a rotation-elastic damping member is provided gradually between the driven shaft and the particular cutting wheel.

摘要： A divided bucket type rotary excavator comprises cutter units constructed by dividing a bottomed cylindrical bucket into plural portions, whose curved sidewalls and bottom plates are provided with bits on their leading edges. The cutter units are arranged about a center shaft radially movably toward and away from the center shaft.The center shaft consists of an outer hollow cylinder having a polygonal cross-section and an inner hollow cylinder slidably fitted in the outer hollow cylinder. There is further provided a hydraulic cylinder arranged in the inner and outer hollow cylinders to move the center shaft telescopically, a set of parallel links connecting the outer hollow cylinder to each the cutter unit, and a link having a length one half of that of the parallel links for connecting a middle point of each lower link of the parallel links to a lower end of the inner hollow cylinder, thereby moving the cutter units radially toward and away from the center shaft by telescopically moving the outer and inner hollow cylinders relatively to each other by means of the hydraulic cylinder.
