Hydro excavation vacuum apparatus that process spoil material onboard the apparatus by separating water from the cut earthen material are disclosed.

A soil boring device and a kit including the same are disclosed herein. The soil boring device includes an elongate tubular body portion; at least one fin member configured to loosen soil when the soil boring device is rotated by a user; at least one handle portion extending outwardly from the elongate tubular body portion; and a water connection subassembly coupled to the elongate tubular body portion. The soil boring device is configured to discharge water from the water outlet of the elongate tubular body portion so as to moisten soil adjacent to the soil boring device, thereby facilitating the forming of the hole in the ground by allowing the soil to be more easily loosened by the at least one fin member. The soil boring device may be provided in conjunction with a soil boring kit that may further include a vacuum collar and a vacuum wand.

Microdredging systems comprising a pumping platform and loading platform are described. In certain embodiments, system operates autonomously and is adapted to allow the loading platform undock from the pumping platform for disposal of the removed sediment.

A piece of submarine mining equipment comprises an equipment body, a plurality of adaptive submarine mining collectors and respective mineral delivery pipes. The equipment body and the adaptive submarine mining collectors are connected through the mineral delivery pipes. The lengths, stretching out of the equipment body, of the mineral delivery pipes can be adjusted under control. The adaptive submarine mining collectors are provided with tracked traveling mechanisms and can autonomously travel under control. An underwater detector is used for detecting the submarine topography and mineral distribution in the vicinity of an operation area, and the traveling path of the submarine mining collectors and a mineral storage vehicle is reasonably planned according to detected information. The multiple adaptive submarine mining collectors simultaneously and independently work and are made light and small, thus reducing damage of mining operations to the submarine ecological environment. The equipment body can travel along flat submarine paths and avoid rough paths. Horizontal vortexes induced by the mining collectors can enhance the mining effect and improve the collecting power under unit power consumption so that fewer water pumps with smaller sizes can be configured, and the mining collectors have a smaller principle dimension, thereby greatly reducing energy consumption and being more environmentally friendly.

The present invention is directed to a drilling fluid reclaimer. The reclaimer has at least one adjustable screen assembly for providing a leveling filter for reclaimed drill fluid. Used drill fluid is placed at the screen assembly at the front the of the screen assembly. The at least one screen is vibrated to separate large particulate matter from liquid drilling fluid. A second screen is provided for additional filtering. Large particulate matter is expelled by a chute at the back of the screen assembly. Drilling fluid passing through the screen is reclaimed for use with a drilling system.
