[002] The mining, geology and civil construction sector has undergone significant advancements in recent years, with the development of more technological products, ensuring more efficient processes, higher performance, greater safety in operations, and enabling better cost-effectiveness.

[003] The movable drill head consists of a closed metal housing, main shaft and secondary shafts, bearings, gears, levers, forming a mechanical assembly, driven by a hydraulic motor, generating low and high speeds, with a fitting compatible with various types of drill rods and drilling tools. The equipment is easier to handle due to the two-speed lever. It has a safety lock on the lever preventing accidental operator changes or equipment vibrations. It also has a compact gear system generating high and low speeds, with the high speed up to 1050 RPM and the low speed from 0 to 65 RPM, which is more efficient, allowing for increased feed rate, thus optimizing drilling and reducing production time. Because it is compact, the production cost of the movable drill head is lower than others, it is lighter and occupies less space.The movable head is universal and can be installed on various equipment models, provided the equipment has a compatible hydraulic system; all these points differentiate it from existing state-of-the-art products.

[008] The object of this application is a cylinder head with a main shaft and three secondary shafts, two of which are splined and meshed, and one meshed, for the purpose of determining the transmission ratio.

[009] The objective of this application is a cylinder head with spur gears of varying sizes, ensuring the correct variation of transmission and speed.

[010] The present application aims to provide a cylinder head with a lever and internal arms for changing the rotation speed; it also has a locking mechanism in the desired position to prevent accidental changes.

[011] The object of this application is a cylinder head operated by a hydraulic motor.

[012] More specifically, the present application proposes a metal head, equipped with a main shaft and three secondary shafts, gears to determine the desired rotation, manual rotation change by lever, assembly actuated by a hydraulic motor.

[013] Therefore, the main objective is a “DOUBLE ROTATION MOVABLE HEAD, WITH GEAR DRIVE SYSTEM, ACTUATED BY HYDRAULIC MOTOR” comprising a closed, isolated external structure, composed of a hydraulic motor, covers, bearings and seals, internally composed of a mechanical assembly formed by bearings, shafts, gears, arms and levers.
