Mowing Machine Packing Unit with Scroll Axles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mowing machines lack the capability to automatically pack collected grass clippings into grass packs, requiring manual handling and not addressing noise suppression and dust leakage issues effectively.
Innovation Solution
A mowing machine equipped with a cutting unit, a conveying unit, and a packing unit featuring a paper-rolling module and a paper-dispensing module, where scrolling axles adjust to accommodate and pack grass clippings with paper, and a compacting unit reduces space occupied by clippings, while a dispensing unit handles the grass packs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If conventional mowing machines are used to collect grass clippings, then grass clippings can be gathered, but manual handling is required and noise suppression and dust leakage are not effectively addressed
Solution Approach 1:
The patent combines the cutting unit, conveying unit, and packing unit into an integrated system. The packing unit merges the paper-rolling module and paper-dispensing module to perform both paper delivery and compacting operations within a single structural framework, achieving automatic packing while controlling overall system complexity
Solution Approach 2:
The scrolling axles serve multiple functions: they guide paper from the paper roll, convey paper to the compacting area, and perform the actual compacting of grass clippings when in the closed position. This multi-functionality reduces the need for separate components for each operation
2Object-affected harmful factors
If grass clippings are collected in a bag by suction, then noise generation is suppressed and dust leakage is prevented, but automatic packing into grass packs is not achieved
Solution Approach 1:
The system uses its own operational processes to achieve packing. The conveying unit that collects clippings feeds them directly to the packing unit, and the scrolling axles that guide paper also perform the compacting function, eliminating the need for separate manual packing operations
Solution Approach 2:
Paper is预先 rolled and positioned on the scrolling axles before grass clippings arrive. The paper-rolling module prepares the paper in advance, so when clippings are conveyed, the packing process can begin immediately without delay

AI summary
A mowing machine includes a cutting unit, a conveying unit for conveying grass clippings away from the cutting unit, and a packing unit including a paper-rolling module and a paper-dispensing module. The paper-rolling module defines an accommodation space for collecting grass clippings from the conveying unit, and includes scrolling axles spaced apart from each other by a gap, and movable between an opened position, where the gap has a predetermined width for allowing passage of the grass clippings from the conveying unit through the gap into the accommodation space, and a closed position, where the scrolling axles rotate to pack the grass clippings with the paper dispensed from the paper-dispensing module.
