- In mining, particularly underground, it is common to apply a thin layer of concrete to sidewall and overhead surfaces in order to further enhance the structural integrity of the newly excavated tunnel or drift.
- The application of this concrete layer is usually made by means of a pressurized system, which consists of concrete being deposited into a hopper and mixer, compressed through a controlled pump, and ejected at a nozzle attached to a length of tubing. During the process, the pump carrier is follows closely by a concrete carrier, which, at the same time, dispenses a supply of concrete into the hopper
- Oftentimes, the pump carrier and the concrete carrier fall out of alignment and spillage occurs. Furthermore, the height of the discharge portion of a concrete carrier varies from model to model. By providing adjustability of the hopper in relation to the concrete carrier, spillage can be minimal or even non-existent.
- It is desirable to the underground mining industry to have the means to vertically and longitudinally adjust the placement of the hopper so as to more accurately accept the concrete from the concrete carrier into the hopper.
- The applicant is aware of attempts in prior art to provide means of portably mixing and dispensing concrete. However, none of the prior art depicts the use of vertical and longitudinal adjustability of a hopper in relation to a concrete carrier.
- Furthermore, the design of the present invention provides such benefits while encompassing a superior element of strength and reliability.
- It is thus the object of the present invention to provide the underground mining industry with a rail system adapted to be mounted to a mining pump carrier whereby said rail system may be vertically and longitudinally adjustable in relation to a nearby concrete carrier so as to provide accurate placement of a hopper attached to said pump carrier in relation to said concrete carrier.
- In one aspect of the invention, there is provided a plurality of pivotal attaching members between pump carrier frame and rail system.
- In another aspect of the invention, the actuator may be hydraulic or pneumatic or any suitable actuating means.
- In another aspect of the invention, a variety of accessories may utilize the functional properties of the present invention.
- Accordingly, the system of the present invention provides vertical and longitudinal adjustability of an attached accessory such as the hopper of the preferred embodiment.
- The utility of this system includes but is not limited to mining applications.
