Abstract

Described herein is an earth auger and pole machine for automated installation of poles in earth banks of access roads to open-pit mines. The earth auger and pole machine is fitted with a mechanic boom comprised of a first link and a second link. The first link has an end attached to a base fixed to a conveyor vehicle, and the other end coupled to the second link. The second link comprises a magazine for loading the poles, an auger system to drill the ground, and an installer to place the poles into the hole. This document also describes a method for installing poles in sequence by using the earth auger and pole machine.

First claim

The invention claimed is:

1. An earth auger and pole machine having a mechanical arm coupled to a transportation vehicle comprising:
an auger system arranged on the longitudinal side of the mechanical arm;
a magazine connected to the longitudinal side of the mechanical arm and arranged in parallel to the auger system; and
an installer arranged on an end of the magazine.

2. The earth auger and pole machine of claim 1 , configured to install poles on the upper side of earth banks of open pit mines.

3. The earth auger and pole machine of claim 1 , further comprising a moving joint to connect the magazine connection with a link of the mechanical arm.

4. The earth auger and pole machine of claim 1 , wherein the installer comprises a piston set to force the pole disposed in one of the slots against the ground.

5. The earth auger and pole machine of claim 1 , wherein the transportation vehicle is a road truck.

6. The earth auger and pole machine of claim 1 , wherein the magazine comprises slots set to store one or more poles.

7. The earth auger and pole machine of claim 6 , wherein the magazine is able to perform a rotational movement of the slots.

8. The earth auger and pole machine of claim 1 , wherein the auger system comprises a support and an auger set to drill holes in the ground.

9. The earth auger and pole machine of claim 8 , wherein the support is set to perform a linear movement along a rail arranged in the longitudinal side of a link of the mechanical arm.

10. The earth auger and pole machine of claim 1 , further comprising a drive that is both hydraulic and pneumatic.

11. The earth auger and pole machine of claim 10 , wherein the power which feeds the earth auger and pole machine is obtained from a compressor and a power socket of the vehicle.

12. The earth auger and pole machine of claim 1 , further comprising a command control.

13. The earth auger and pole machine of claim 12 , wherein the control command is set to control the mechanical arm, the auger system, the installer and the magazine.

14. A method for pole installation using the earth auger and pole machine of claim 1 , comprising:
i. loading the poles in the magazine, the magazine comprising slots;
ii. moving the earth auger and pole machine to the installation location by the transportation vehicle;
iii. unfolding the mechanical arm;
iv. placing a second link of the mechanical arm on the desired installation location;
v. activating the auger system for perforating a hole in the ground;
vi. placing the pole over the hole;
vii. activating the installer for insertion of the pole in the hole;
viii. performing an opening movement of the magazine;
ix. activating the magazine for performing the rotational movement of the slots;
x. moving the earth auger and pole machine to the next installation location by the transportation vehicle;
xi. repeating steps iii, iv, v, vi, vii, viii, ix and x until the poles contained in the magazine run out;
xii. returning to step i.

15. The method for pole installation of claim 14 , wherein steps iii, iv, v, vi, vii, viii and ix are performed by a command control.

16. The earth auger and pole machine of claim 1 , wherein the mechanical arm is provided with moving joints set to support and move it.

17. The earth auger and pole machine of claim 16 , wherein the mechanical arm comprises at least eight degrees of freedom.

18. The earth auger and pole machine of claim 16 , wherein the mechanical arm comprises a first link and a second link.

19. The earth auger and pole machine of claim 18 , wherein the auger system, the magazine and the installer are arranged on the second link of the mechanical arm.

20. The earth auger and pole machine of claim 18 , further comprising a base coupling between the first link of the mechanical arm and the transportation vehicle.

21. The earth auger and pole machine of claim 20 , wherein the transportation vehicle is a road truck, and the base is coupled to a body of the road truck.

22. An earth auger and pole machine having a mechanical arm coupled to a transportation vehicle comprising:
an auger system arranged on the longitudinal side of the mechanical arm;
a magazine connected to the longitudinal side of the mechanical arm and arranged in parallel to the auger system; and
an installer arranged on the magazine,
wherein the transportation vehicle comprises a bed and the earth auger and pole machine is capable of installing poles above a height of the bed.
