Sealed Container Grinding and Rinsing for Spill-Safe Pesticide Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural spraying systems face challenges in safely handling and treating plant protection product containers, which can be hazardous, leading to risks of spillage, musculoskeletal disorders, and reduced worksite throughput.
Innovation Solution
A container grinding system with a sealed box, safety devices to inhibit grinder operation until the box is closed, grinding shafts with knives, a filtering basket, and rinse nozzles to secure the grinding process, reducing the risk of spillage and optimizing container handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If containers are handled manually for transfer and treatment, then the operator has direct control over the process, but the risk of accidental spillage and contact with plant protection products increases
Solution Approach 1:
The patent introduces an automated transfer system with sealed containers as an intermediary between the plant protection product storage and the spray system. This mediator automatically transfers the product without operator intervention, eliminating direct handling while maintaining process control. The sealed container system acts as the intermediary that resolves the contradiction between safety and operational control.
2Productivity
If containers are opened beforehand for transfer through an incorporation hopper, then the transfer process is simple, but the risk of spillage and exposure to plant protection products increases
Solution Approach 1:
The patent employs sealed flexible containers with integrated discharge mechanisms to transfer plant protection products. These sealed shells maintain containment during transfer while allowing controlled dispensing, thus maintaining transfer efficiency without the spillage risks associated with open hoppers. The flexible sealed container resolves the contradiction between transfer speed and spillage prevention.
3Reliability
If empty containers are collected and treated separately, then proper treatment can be ensured, but the overall worksite throughput is reduced
Solution Approach 1:
The patent merges the container treatment function directly into the automated transfer system. The grinder is integrated into the transfer mechanism, allowing containers to be automatically ground and processed within the same automated sequence that handles product transfer. This combination eliminates separate handling steps while maintaining safe treatment, thus resolving the contradiction between treatment safety and throughput.
4Ease of manufacture
If containers are ground in an open system, then the grinding process is simple, but the risk of splashing and pollution from plant protection products increases
Solution Approach 1:
The patent creates a sealed enclosed environment for the grinding process, effectively isolating the plant protection products from the external atmosphere during treatment. This enclosed space prevents splashing and pollution while containing the grinding operation, thus resolving the contradiction between grinding simplicity and pollution prevention without requiring complex additional equipment.

AI summary
A container grinding system having a box equipped with a closing device coupled to a first safety device, the box having a container introduction opening arranged in a top part of the box and capable of being closed by the closing device, the grinding system having a grinder having at least one grinding shaft for shredding chipped containers, a filtering basket recovering the ground material from the grinding of containers, and a set of rinse nozzles, the grinding system being configured so that following the introduction of a container into the box for grinding the same, the first safety device inhibits the operation of the grinder as long as the closing device does not ensure closing of the box.
