Riding Mower Deck Air Intake and Shielding Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional riding grass-mowers experience grass clogging during collection, leading to inefficiencies in mowing and mulching processes.
Innovation Solution
Incorporation of a mowed-grass guiding passage with an air intake hole and a shielding member that can be attached and detached, featuring a shielding plate and mowed-grass branching member to guide grass efficiently and prevent clogging, allowing for smooth discharge and easy conversion between mowing types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional riding grass-mower performs grass collecting work, then grass discharge is performed, but mowed-grass clogging occurs
Solution Approach 1:
The patent extracts the air intake function from the overall mower system by providing a dedicated air intake hole at the top of the mowed-grass guiding passage. This separate air intake path allows air to be drawn into the guiding passage, creating airflow that prevents grass clogging without interfering with the primary mowing and discharge functions.
Solution Approach 2:
The air intake hole acts as an intermediary element that introduces air into the mowed-grass guiding passage. This air flow serves as a mediator that facilitates smooth grass discharge by preventing clogging, thereby resolving the contradiction between maintaining discharge efficiency and preventing clogging.
2Adaptability or versatility
If the mower is converted to mulching type, then grass is guided to mowing blades, but device complexity increases
Solution Approach 1:
The patent implements a dynamic shielding member that can be attached and detached based on the desired mowing type. When converted to mulching mode, the shielding member is attached to block the discharge passage and guide grass to the mowing blades. When in collection mode, the shielding member is detached to restore normal discharge. This dynamic configuration allows the mower to adapt between different mowing types without permanent structural modifications.
Solution Approach 2:
The shielding member is designed as a separate, detachable component rather than an integrated permanent structure. This segmentation allows the shielding function to be added or removed independently, simplifying the overall device structure while maintaining versatility. The shielding member includes a shielding plate and branching member that can be easily attached to and removed from the mower body.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures smooth grass discharge during collection, suppresses clogging, and facilitates efficient mulching by guiding grass to the mowing blades, improving work efficiency and reducing the complexity of switching between mowing types.
Implementation Method 1
an air intake hole (1210) is provided at such a portion of the mower deck top-plate member (1200) as is placed at a top of the mowed-grass guiding passage (1400)... since the air intake hole (1210) is provided, air intake can be performed, and generation of the mowed-grass clogging at the time of grass collecting work is able to be suppressed
Implementation Method 2
a shielding member (4000) which is configured to shield the mowed-grass guiding passage (1400)... and is configured to guide the mowed grass to respective sides of the pair of the mowing blades (1110, 1120)
