Definitions
- the present utility model patent belongs to the field of forestry tree felling and delimbing equipment and its subject-matter is a practical and innovative robust tree cutting equipment utilizing two-degree hydraulic shear technology. freedom, that is, with angular inlet and swivel positioning on the flat axis itself, where it can be coupled with lifting equipment, crane and the like with hydraulic preparation and to which original constructive arrangement was given, with a view to improving the its use and performance in relation to other models usually found in the market.
- This equipment is very similar to the front portion of the scissors, but of more robustness and structure, whose articulation of movements both guillotine and positioning are actuated by three manually operated hydraulic pistons operated by levers or control. remote, in order to perform severe pruning services on urban and even rural trees, whose operation can be creeping (ground level) or aerial (treetop).
- the electro-hydraulic roughing machine has great biting and cutting power and allows you to cut branches up to eight centimeters in diameter, as well as serrated side to the cutting element that promotes the correct retention of the branches at the same time as it is. sectioned off.
- Trees have a very marked ability to expand their crowns, even those whose crowns are of less exuberant characteristics in both rural and urban areas, such growth causing invasions of overhead electricity networks, interfering with structures of high buildings, as with their roots, and grow randomly without any intrinsic relationship to aesthetics.
- Branch growth has a very intense natural shearing force and can naturally break electrical cables, poles and even more robust structures such as slabs and bridge structures, so when this interference is necessary, branch pruning or even those of lower altitude and which may compromise the physical safety of such facilities and constructions. Poor points of the prior art
- the hydraulic chopper has varying degrees of mobility as it is fully articulated and can be positioned at any entry angle to gain access to a more difficult to reach branch.
- the present patent has been designed to achieve the lowest possible aerial branch pruning equipment, conveniently configured and arranged to allow you to perform branch pruning more effectively and perform its functions with unrivaled efficiency and versatility. , without the drawbacks already mentioned.

- the "Arrangement Introduced in ELECTRIC HYDRAULIC TREE CHOPPER" object of the present invention, designs an electro-hydraulic chipper developed as a solution for thinning and pruning trees and shrubs. , or even for cutting, by remote control or lever drive and can be coupled to cranes, or other hydraulically prepared equipment and / or devices, whose operation can be low (ground level) or overhead (treetop) ).
- the structure of the equipment is built in steels with structural and mechanical qualification and is basically composed of three parts, defined as coupling, turning axis and the scissors itself.
- the coupling is the rear part of the equipment, responsible for the connection to the crane, or other equipment or devices and has dimensions and typologies. varying in design, depending on the location of the coupling, to which each crane boom model will apply a dimensional coupling.
- the pivot axis is the intermediate part of the cutting equipment, responsible for the rotating and articulating systems of the equipment and at this point, the greatest momentum and shear forces of the machine are concentrated on the main shaft.
- the equipment's transverse slewing system consists of a double hydraulic piston, with extensive cross-linked rod, technology that provides turns greater than one hundred and eighty degrees, with the machine's total transverse slewing being at least two hundred and ten degrees and the Total longitudinal joint is at least one hundred and twenty degrees.
- the scissors are the front part of the cutting equipment responsible for thinning and / or pruning and this cutting region is composed of a pair of special steel knives, one fixed knife, and the other movable one, the knife. serrated furniture in order to seize the material in the cutting region.
- tooth systems one on the movable side and one on the fixed side, in order to hold the cut material and on the fixed knife side, the tooth system articulates through spring springs. compression, in order to "break" the rigidity of the system, allowing the knurl to shape and hold the cut material.
- the maximum opening dimension of the knife is five hundred millimeters and the transverse rotation of the scissors reaches a total of two hundred and ten degrees, one hundred and ten degrees to each side of the equipment.
- the scissor hydraulic system works with three double action pistons, responsible respectively for the longitudinal joint, transverse turn and cut.
- the flow rate is also variable, and is usually seventy liters per minute and requires a voltage supply of twelve or twenty four volts, so that the system can be operated by remote control.
- the scissor equipment is equipped with electro-hydraulic control to drive the three double action pistons and should therefore be hydraulically and electrically powered, with pair of hoses and with the twelve or twenty four volt cable.
- Scissor hydraulic connections to third party equipment are quick coupler type, whose control supply hoses and electric cable vary in length depending on the distance between preparation and the last boom of the equipment.
- the equipment has electrical load insulating protections, made of plastic material, at specific points of the equipment.
- the machine is sized for seven hundred and fifty kilogram (750 Kgf) knife acting force cutting and the cutting speed is directly related to the hydraulic pump flow with estimates of a normal production of two and a half thousand. kilograms per hour (2500 kg / h) of chopped material.
- the crane coupling machine has a total length of 1800 mm (1800 mm), a total width of 900 mm (900 mm), a total height of 1,330 mm (1030 mm), and a weight of 200 meters. thirty kilograms (230 Kg), the useful length of the machine after coupling of one thousand three hundred millimeters (1300 mm).
- the electro hydraulic tree pruning chopper (1) comprises a robust high shear hydraulic shear (2) consisting of three hinged frames, namely hitch frame (3), hinge frame (4) ) axial and angular and clamping structure (5), each of which is actuated by a hydraulic piston (6).
- the rear coupling structure (3) is basically comprised of a short "U" profile segment with retaining holes at the rear end, a rod holder (7) for hydraulic piston coupling (6) and a tunnel shaft (8) transverse at the front end for coupling the pivot frame (4).
- the hinge frame (4) is a metal profile chassis frame with quadratic morphology in which at the base of one face there is a sturdy "U” bearing (9) with transverse shaft that engages the coupling (3).
- the mordant structure (5) resembles the delineation of a classic "revolver” and bears at the posterior portion an orthogonal discoid formation (14) with a central shaft sleeve (15), which engages with the pivot axis (11). ) of the bearing disc (10) of articulation structure (4) and extends into an elongated parabolic projection (16), into whose end hole, a third hydraulic piston (6) is coupled.
- the mordant structure (5) bears in the middle portion an axial articular bearing (17) with an orthogonal axial joint, in which the tilting guillotine (18) is coupled to the mordant structure (5), which has an aspect elongate curvilinear and where the other end of the third hydraulic piston (6) is fixed.
