Technical Field

The invention belongs to the technical field of aquatic weed collecting devices, and particularly relates to a handheld collector and an aquatic weed collecting method.

Background

When detecting the river course environment or when clearing up the river course, all can involve gathering pasture and water. Because the aquatic weeds grow in different depths in water and different growing environments, the aquatic weeds are inconvenient to collect directly by hands, and usually need to be collected by means of equipment or tools, and although the existing aquatic weed collecting boat is mature in technology, the aquatic weed collecting boat is inconvenient to apply to small water bodies and local small-quantity aquatic weed collection; in addition, the aquatic weeds grow in water for a long time and are relatively soft and smooth, and most aquatic weeds are mutually connected and rooted in the bottom mud and are not easy to tear out. Most of the existing aquatic weed collecting tools adopt a structure similar to a pliers and collect aquatic weeds by using a clamping force mode, and when the aquatic weeds are collected by adopting the mode, if the clamping force is small, the aquatic weeds are easy to slip and cannot be pulled out; if the clamping force is too large, the aquatic weeds are easily pinched off, so that the roots of the aquatic weeds are left in the water, and the aquatic weeds are not convenient to collect.
