Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gear reducer mechanisms for surface-drilling rigs face difficulties in applying pneumatic or hydraulic hammer functions to augers, particularly in drilling through hard materials like concrete or compact stone, due to technical challenges in supplying pressure and maintaining hammering movements.
Innovation Solution
A gear reducer mechanism with a mechanical hammer system that uses a relative longitudinal movement between the auger fixing hole and the surrounding gear reducer mechanism, incorporating an end-of-stroke piece and stop with protuberances or teeth to create a hammering effect, eliminating the need for pneumatic or hydraulic systems and leveraging the auger's weight for drilling resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If pneumatic or hydraulic hammer systems are used to drill hard materials, then drilling capability through concrete or compact stone is improved, but device complexity and cost increase due to requiring pressure supply systems and maintaining hammering movements
Solution Approach 1:
The patent replaces complex pneumatic or hydraulic hammer systems with a simple mechanical hammering mechanism. The mechanical hammer consists of a hammering element that can move longitudinally relative to the auger, activated by the operator through manual force applied to the handle. This mechanical approach eliminates the need for pressure supply systems while maintaining effective hammering capability for drilling through hard materials like concrete or compact stone
Solution Approach 2:
The mechanical hammer system allows the operator to directly control the hammering action through manual operation. The operator applies force to the handle, which translates into controlled hammering movements of the auger tip against the ground. This self-service mechanism eliminates the need for external power sources or complex control systems, reducing device complexity while maintaining drilling capability

Function Achieved in This Case
This solution provides an efficient and cost-effective mechanical hammering mechanism that effectively drills through hard materials without the complexity and expense of hydraulic or pneumatic systems, maintaining rotation transmission and absorbing vibrations to prevent machine disruption.
Implementation Method 1
a gear reducer mechanism (10) to provide torque to a surface drilling auger (12)... the fixing hole (16) has a relative longitudinal movement with respect to the element that transmits the rotation from the means of generating the rotating movement
Implementation Method 2
the contact surface of the end-of-stroke piece and the stop piece of the auger fixing hole have protuberances, teeth or similar, which when rotating one against the other at said maximum displacement point, create jumps that cause the fixing hole of the auger to transmit to the auger itself a hammering movement against the ground to be drilled

AI summary
The present invention relates to a gear reducer mechanism of an auger for surface-drilling rigs, commonly used in the construction of piles, which rotates an auger, via motorised means, to achieve said drilling of the surface on which the auger strikes. This gear reducer mechanism has, advantageously, a configuration that includes at least one auger fixing hole with rotary movement and with longitudinal movement with respect to the rotary transmission part, an end-of-stroke piece of the maximum longitudinal displacement of the fixing hole and a stop of the auger fixing hole that comes into contact with the end-of-stroke piece when the maximum relative longitudinal displacement is reached, wherein this configuration allows to create jumps that cause the fixing hole of the auger to transmit to the auger itself a hammering movement against the ground to be drilled.
