Integrated Herbicide Sprayer for Skid Loader Tree Cutter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tree cutting apparatuses, such as chain saws and circular saws, are prone to frequent failure and require manual herbicide application on tree stumps, disrupting operation and increasing safety hazards, as they need to be stopped and operators must exit heavy equipment to apply herbicides.
Innovation Solution
A dual-action tree cutting apparatus with an integral herbicide spraying system that allows operators to apply herbicide without stopping the machine or leaving the vehicle, utilizing a sprayer integrated with the skid loader or similar heavy equipment, enabling continuous operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual herbicide application is used after tree cutting, then herbicide can be applied to tree stumps, but operation must be stopped and operator must leave the vehicle
Solution Approach 1:
The patent combines the tree cutting apparatus with an integral herbicide spraying system, merging two separate operations (cutting and herbicide application) into a single integrated device. The sprayer is mounted on the same platform as the cutting mechanism, allowing both functions to be performed simultaneously without requiring the operator to leave the vehicle or stop operation.
Solution Approach 2:
The device is designed with multi-functionality, serving both as a tree cutting apparatus and a herbicide spraying system. The integrated design allows the same platform to perform multiple tasks - cutting trees and applying herbicide - eliminating the need for separate equipment and operations.
2Power
If heavy equipment is used for tree cutting, then cutting capability is improved, but safety hazards from flying chips and debris increase
Solution Approach 1:
The patent introduces a protective shield or screen as an intermediary element between the cutting blade and the operator/environment. This shield intercepts and contains flying chips and debris, preventing them from reaching the operator or surrounding areas, thus reducing safety hazards while maintaining the power of the cutting mechanism.
3Ease of operation
If chain saws are used for tree cutting, then portability is improved, but reliability decreases due to frequent failure from moving parts
Solution Approach 1:
The patent extracts the herbicide spraying function from the traditional chain saw design and integrates it into a separate, dedicated spraying system mounted on the same platform. This separation allows the cutting mechanism to maintain its portability while the spraying system provides reliable herbicide application, avoiding the reliability issues of multi-functional chain saws.
4Strength
If circular saws are used for tree cutting, then strength and robustness are improved, but device size and bulk increase
Solution Approach 1:
The patent segments the device into distinct functional modules: a compact cutting mechanism and a separate spraying system. This segmentation allows each component to be optimized independently - the cutting mechanism remains compact while the spraying system adds the necessary herbicide application capability, avoiding the bulk of a fully integrated circular saw design.

AI summary
Taught herein is an improvement over existing mechanisms for cutting down trees. According to one embodiment the instant invention is a tree cutter that is mountable on a skid loader or similar piece of heavy equipment. The tree cutter includes an integral liquid sprayer system that can be activated by the operator of the vehicle to which it is attached. In some embodiments the liquid that is dispensed is a herbicide that can be applied to the tree that has just been felled in order to make certain that it will not produce shoots that can potentially grow to replace the tree that had just been cut. It is therefore a general object of the present invention to provide an improved dual action tree cutting apparatus that also provides for application of a herbicide by the operator without stopping the rotation of the cutting blade or exiting the vehicle.
