Mower Deck Washing Device with Auxiliary Side Wall Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mower units struggle to effectively clean the entire inner surface of the mower deck and rotary blades, as conventional washing devices often fail to reach and remove debris efficiently from these areas.
Innovation Solution
A mower unit design featuring a washing device with a water supplying unit positioned above the mower deck and water discharging units through auxiliary side walls, ensuring focused water distribution to all rotary blades, along with a water supplying pipe system that maintains equal flow rates and pressures to ensure thorough cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional washing device is used, then the structure is simple, but the cleaning effectiveness on the entire inner surface of the mower deck and rotary blades is insufficient
Solution Approach 1:
The washing device is segmented into multiple water discharging units (first, second, third water discharging units) positioned at different locations through the auxiliary side walls. Each unit discharges water to specific rotary blades, ensuring comprehensive coverage of the entire inner surface and all blades through distributed water delivery points.
Solution Approach 2:
Water is discharged from multiple spatial dimensions through auxiliary side walls rather than from a single location. The water supplying unit is positioned above the top wall while discharging units are positioned through side walls, creating a three-dimensional water distribution network that encompasses the entire mower deck interior.
2Reliability
If water is discharged from above the rotary path, then the entire rotary blades can be cleaned effectively, but the water flow may scatter outside the mower deck
Solution Approach 1:
Each water discharging unit is specifically positioned to discharge water locally to its associated rotary blade. The first water discharging unit discharges to the first rotary blade, the second to the second rotary blade, and the third to the third rotary blade, ensuring focused and controlled water application without scattering.
Solution Approach 2:
The auxiliary side walls act as intermediaries that guide and confine the water flow from the water supplying unit to the rotary blades. The water supplying pipe unit, disposed within the mower deck rear space, serves as an intermediary conduit that delivers water through controlled paths to prevent scattering while maintaining effective cleaning coverage.
3Ease of operation
If the water supplying unit is disposed upwardly of the top wall, then the connecting operation is convenient, but the water supply may be interfered with from the outside
Solution Approach 1:
The water supplying pipe unit is nested within the mower deck rear space, which is delimited by the outer faces of the auxiliary side walls. This nested arrangement protects the water supply system from external interference while maintaining convenient access for connecting operations through the top wall position.
Solution Approach 2:
The auxiliary side walls serve as protective intermediaries that shield the water supplying pipe unit from external interference. The pipe unit disposed within the rear space behind these protective walls is isolated from external harmful factors while the water supplying unit remains accessible from above for convenient connection operations.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design allows for efficient washing and cleaning of the mower deck and rotary blades, reducing debris accumulation and making the washing process more convenient by aligning the water flow with the rotary paths, thus enhancing operational efficiency.
Implementation Method 1
a single water supplying unit disposed upwardly of the top wall for supplying washing water
Implementation Method 2
a water supplying pipe unit interconnecting and communicating the water supplying unit to the first, second and third water discharging units
Implementation Method 3
a first water discharging unit disposed through said first auxiliary side wall for discharging water to said first rotary blade
