A floating adjustable pond electric lawn mower

Abstract

The invention discloses a floating adjustable pond electric mower. The electric mower comprises a floating body, a driving part, a lifting mechanism and a rotary mowing part, wherein the driving part, the lifting mechanism and the rotary mowing part are arranged in the floating body; and the rotary mowing part is driven by a direct current motor, and the extension length of a blade is controlled by the lifting mechanism, thus achieving a purpose of controlling a mowing height. The electric mower can be not only dragged by a boat but also operated and moved by an operator standing on a river bank through a rod or a rope, so that the operator can cut stubbles of waterweeds without moving into the water; the electric mower is adjustable in waterweed cutting height, good in stability, and capable of managing and controlling the waterweeds in a crab pond, and meanwhile, the electric mower is low in mowing labor intensity, reduces interference to the living habit of river crab which hides in the daytime and comes out at night, and can effectively overcome shortcomings of the prior art.

Description

technical field [0001] The invention relates to an auxiliary appliance for aquaculture, in particular to an appliance for cutting aquatic plants in crab ponds. Background technique [0002] There is a fishing proverb: If you want to raise a pond of crabs well, you must first plant a pond of grass. Especially in the high temperature season, the management and protection of aquatic plants is the key to the success or failure of river crab breeding. Planting appropriate amount of aquatic plants in the crab pond can not only purify the water quality, but also adjust the water temperature, creating a good ecological environment for the growth of river crabs. At the same time, aquatic plants are also the natural bait of river crabs, and they are also the aids in the removal of shells during the growth process of river crabs. However, when the aquatic plants "grow wildly and produce water", the aquatic plants begin to absorb carbon dioxide in the air, and reduce or stop absorbing ...

AI Technical Summary

Problems solved by technology

The current method of manually mowing aquatic plants is: people have to wear waterproof clothes to work in the pool, and push the mowing knives by hand. The height of the hand-held knives cannot be uniform, so the height of the mowing cannot be controlled.

On the other hand, the manual mowing operation is usually during the day, and the living habit of river crabs is nocturnal, that is, they rest during the day and look for food at night. Manually entering the water and mowing not only disrupts the life of the crabs, but also disturbs the water in the pool, which is not conducive to the crabs. Normal growth, and manual cutting of aquatic plants is labor-intensive, labor-intensive and time-consuming, and the height of aquatic plants varies after cutting, which is extremely unfavorable to the management of river crab breeding
