Definitions
- the invention relates to a set of clamps or clams with hydraulic drive for digging holes.
- This type of tools with digging clams can act on any terrain and is basically composed of a shell or tubular chassis that stores the drilling load within it, and within which a set of concave contour spoons or clams is driven by a jack. hydraulic through a transmission bars articulated to a beam that moves through the chassis and to pins or mobile bushings of each clam. Excavation movements are transmitted by means of articulation pins or pins between the transmission bars and the respective clams or spoons.
- the invention seeks to present the tool as a complete set as described below.
- Figure 1 presents an isometric view of the tool.
- Figure 2 is a schematic view or section of the tool for digging in its two positions with the clamps or clams open and closed.
- Figure 3 is a top view in section from the transmission bars and where the clams are observed.
- the tool consists of a storage chassis tube (1) into which the perforated load is collected.
- a hydraulic device (3) as a cylinder or hydraulic jack (13) whose function is the opening and close the spoons or clams (2).
- the clams (2) are responsible for drilling the ground, whether it be dirt, gravel, sand, etc; so that in their deep advance on the ground they collect inside the earthy content and store it inside the tube (1).
- Figure 2 shows the beam (7) when moving by action of the hydraulic jack (3), which makes the transmission bars (4) through pins and mobile bushings (11) in the clams, exert a movement of rotation of the clams (2) around the supports in the pins and fixed bushings (5).
- sealing levers (9) Inside the tube or housing (1) and through its internal length are two sealing levers (9), which move sealing gates (8) that prevent the stored load from sliding through the space that forms between the jaws ( 2) and the storage tube (1).
