"Shovel" - what is it, definition of the term
A digging implement with a broad, usually metal blade mounted on a short handle is designed to lift, transport, and deposit bulk substances such as soil, sand, or gravel; the curved blade directs material toward the operator, while the handle supplies leverage for efficient force. In pest‑control settings, this tool facilitates excavation of burrows and removal of debris where rodents such as rats and mice inhabit.
Detailed information
A digging implement designed for moving loose material consists of a broad, typically metal blade attached to a long handle. Blade width ranges from 15 cm for compact models to 35 cm for heavy‑duty versions; thickness varies between 2 mm and 6 mm depending on intended load. Handles are manufactured from wood, fiberglass, or reinforced polymer, offering grip lengths of 80–120 cm to accommodate user stature and leverage requirements.
Key components include the blade, which may feature a straight or slightly curved edge; the collar, which reinforces the joint between blade and handle; and the grip, often covered with rubber or textured polymer to reduce slippage. Some versions incorporate a toe edge for precise penetration of compacted soil.
Material selection influences durability and weight. Carbon steel provides high tensile strength and edge retention but requires protective coating to resist corrosion. Alloy steel offers a balance of strength and rust resistance. Plastic or composite blades reduce weight for light tasks but are unsuitable for heavy excavation. Handles of hardwood deliver natural shock absorption, while fiberglass reduces fatigue through vibration damping.
Primary applications encompass garden bed preparation, trench digging for irrigation, demolition of drywall, and loading of loose aggregates in construction sites. In pest control, the tool serves to expose subterranean tunnels created by rodents such as rats and mice, facilitating placement of bait stations or mechanical traps. By clearing leaf litter and debris, it eliminates shelter that these animals use for nesting, thereby reducing population density in residential and agricultural settings.
Safety protocols demand the following actions:
- Inspect the blade for cracks before each use.
- Wear gloves and steel‑toe footwear to protect hands and feet.
- Position the body with knees slightly bent, keeping the back straight while lifting.
- Avoid overreaching; keep the load close to the body.
- Store the implement in a dry area to prevent rust formation.
Routine maintenance extends service life. After each session, remove soil particles from the blade, wipe with a damp cloth, and apply a thin layer of oil to steel surfaces. For wooden handles, sand rough spots and reapply a protective sealant annually. Sharpen the cutting edge using a bench grinder or file when it no longer penetrates soil efficiently. Periodic inspection of the joint ensures the collar remains secure, preventing accidental separation during operation.
