Description
Modern wood harvesting relies on harvesters, a type of heavy forestry equipment employed in cut-to-length logging for felling, delimbing, and bucking trees. Harvesters are are similar in configuration to medium-sized hydraulic excavators, but instead of having a bucket at the end of the stick, they have a mobile harvesting head that the operator can rotate around both its vertical and horizontal axes.
Harvesting heads rely on several hydraulic motors and cylinders to activate their different processing functions. The pressurized hydraulic fluid is brought to the harvesting head through flexible hydaulic hoses. Those hoses, fastened along the boom and stick of the machine, are let to hang loose over the distance between the end of the stick and the harvesting head and are screwed on the valve bodies, located under the protective covers of the havesting head.
This configuration creates several issues, among which:
= Requiring the time-consuming process of removing of the protective covers to perform routine replacement of the hoses.
= Removing the protective covers allows contamination by debris of the delicate electro-mechanic systems located under the covers = The continuous abrasion of the hoses against the edges of the protective covers during operation.
Our invention eliminates the need to remove the protective covers by allowing the consumable hoses to be connected to a non-consumable, permanently fixed extention protuding outside the covers, bridging the hoses to the the valve bodies.
The design as proposed is not self-evident since the scores of designs tested that were different from the one we are proposing lead to problems such as:
= The junctions between the extention sections tend to separate under the significant stress conditions. The solid design of the part is required to withstand the vibration and pressure experienced.
= Other designs risk damaging the valve body if something impacts the hose-extension assembly. This invention eliminates this risk by fitting tightly inside the cover holes, preventing the extension from tilting and stressing the valve body.
= Installation and servicing the part is significantly more difficult without the features incorporated in this design. The hexagonal faces machined at the far end of the extension allows for servicing without removing the covers.
