Overview
ISO 5680:1979 - Equipment for Working Soil - Tines and Shovels for Cultivators - Main Fixing Dimensions is an international standard published by ISO, the International Organization for Standardization. This standard establishes the main fixing dimensions for interchangeable shovels designed to fit specific tines used on soil cultivators. Its scope centers on standardizing the connection points at the lower portion of tines, which support shovels with working widths of up to 400 mm. By setting out these key dimensions, ISO 5680:1979 helps ensure interoperability and ease of maintenance for agricultural machinery across manufacturers and markets.
Key Topics
-
Fixing Types:
The standard outlines three main fixing types for attaching shovels to tines:
- Type 1: One hole
- Type 2: Two holes
- Type 3: Two holes, heavy type
-
Main Fixing Dimensions:
The standard specifies critical dimensions that include:
- Radius of curvature (tines and shovels)
- Contact line angle
- Distance between fixing bolt holes
- Bolt hole diameter
- Dimensions for square neck bolt holes
- Countersink angle for bolt holes
-
Classification and Limitations:
While ISO 5680:1979 addresses the principal fixing dimensions, it does not limit further design or configuration changes, nor does it specify the materials or manufacturing methods for shovels and tines.
Applications
ISO 5680:1979 serves a crucial role in agriculture, particularly in the standardization of soil cultivation equipment. Its practical applications include:
- Interchangeability: Standardized fixing dimensions enable shovels from different manufacturers to fit tines that conform to ISO 5680, offering flexibility in sourcing and replacing parts.
- Simplified Maintenance: With fixed dimensions, maintenance teams can replace worn shovels without concern for compatibility, reducing equipment downtime and inventory complexity.
- International Trade: Manufacturers and distributors can trade components globally with the assurance that standardized fixing points will fit machinery complying with ISO 5680.
- Enhanced Equipment Lifespan: Ability to use a wide variety of shovels on standardized tines extends the operational life and versatility of soil cultivators.
Use of this standard is prevalent among makers and users of agricultural machinery such as cultivators, tillers, and soil working implements. Ensuring compliance with ISO 5680:1979 helps agricultural operations achieve not only efficiency and reliability, but also safety in equipment usage.
