Abstract

The invention provides a grass mower and particularly relates to an underwater grass mower which is simple in structure, convenient to take and good in mowing effect. The bottom of the mower will not be rubbed. The underwater grass mower is especially suitable for a fisherman to use when the fisherman makes a net and can also be used for removing water grass and impurities in a cultivation pond. The underwater grass mower is in a V shape and made of steel plates. Outer rims of the two sides of the grass mower are provided with saw-toothed sharp blades. Only one rope is tied to the upper end of the V shape, the grass mower is thrown into water and rapidly pulled after arriving at the front of water grass and the water grass can be easily cut from the roots. The water grass floats on the water level and drifts away with the wind. Meanwhile, the water grass can be dragged out of the water level in the manner of throwing the grass mower so as to achieve the aim of removing weeds at the water bottom. The underwater grass mower has the advantages that the grass mower is made of two saw-blade-shaped steel plates and the front ends of the steel plates are riveted with rivets. During mowing, if two sides of the grass mower meet obstacles and the grass mower can not go through, as long as a rope is pulled with force, a nylon line in a positioning hole can be sheared and the included angle between two blades is narrowed. The grass mower is pulled out so as to prevent the bottom of the grass mower from being rubbed.

Description

A kind of grass cutter under water

(1) technical field

The present invention relates to a kind of grass cutter under water, especially a kind of simple in structure lightweight, the effective and grass cutter of hanging end anything but of mowing.

(2) background technology

The throwing type of existing various shapes is grass cutter under water, complicated structure mostly, and weight ratio is heavier, carries inconvenience, and manufacturing cost is higher, and manufacturing process is complicated, and the mow shortcoming of not thorough and easy hanging end of ubiquity.

(3) summary of the invention

The present invention is in order to make up the deficiencies in the prior art, provide a kind of manufacture simple, with low cost, easy to carry, effective and the grass cutter under water of hanging end not of mowing, convenient especially fishing people uses while beating nest, also can support pasture and water and foreign material in pond for removing.

The present invention is achieved by the following technical solutions:

The present invention under water its special character of grass cutter is: the shape of this grass cutter is " v " font, of steel plate, make, the outer rim on both sides has jagged sharp knife edges, only with a rope, lie in the front end of " V " word, throw the place ahead of pasture and water, pull fast after sinking to the bottom, great majority can easily cut off pasture and water from root, pasture and water float on the surface of the water with the wind and float, and also the mode of the available grass cutter of jettisoninging is pulled out the water surface pasture and water, realize the object of the water-bed weeds of cleaning.

The invention has the beneficial effects as follows: because the shape of this grass cutter is " V " font, two limits are two blades making with two saw strip steel plates, the circular hole of forward end with rivet riveting together, only with a rope, lie in the front end of " V " word, if both sides run into barrier when mowing simultaneously, cannot by time, can be by dwindling angle between two blades until 0 degree, or lean to one side by coming, through barrier, to avoid hanging end.

This grass cutter is to be assembled by shape, identical two two saw blade shape blades of size, and materials are saved cheap, and processing and fabricating is simple, easy to carry.

(4) accompanying drawing explanation

Accompanying drawing is the present invention's grass cutter figure under water

Wherein: 1 blade, 2 locating holes, 3 rivets, 4 rope holes.

(5) embodiment

Be illustrated in figure 1 the present invention's a kind of specific embodiment of grass cutter under water.Comprise two blades (1), locating hole (2), rivet (3), rope hole (4).Two blades of saw blade shape, be the circular hole of forward end with rivet riveting together, the present invention under water grass cutter passes locating hole (2) repeatedly with No. 6 thick nylon fishing lines in use, and fasten, play the effect of fixing angle between two blades, in rope hole, fasten the rope of appropriate length, just can jettisoning cutting operation.

If grass cutter both sides run into simultaneously barrier be difficult to by, as long as pull with strength rope, two blades just can be cut off the nylon wire in locating hole as scissors, angle between two blades is diminished, and tail end distance shortens, or blade is leaned to one side, passed through smoothly, avoided hanging end.

Due to rope hole be shaped as circular arc strip, when the angle between two blades diminishes, rope hole shortens, but can not cut short rope.

If while running into the more difficult foreign material of removing, can in the tail end circular hole of two blades of grass cutter, fix respectively a rope, grass cutter is thrown to foreign material the place ahead, pull two ropes simultaneously, foreign material are cut off or are pulled out the water surface.

Because the outer rim of two blades of this grass cutter has jagged sharp knife edges, both conveniently cut off pasture and water, be convenient to again tangle the pasture and water of having cut off and pull it the water surface.Meanwhile, obsolete time, be also convenient to by fasten rope be wrapped in above.

The convenient especially fishing of this grass cutter people uses while clearing up in water weeds while beating nest, also can be for removing pasture and water and foreign material in cultivating pool.

Claims

1. a grass cutter under water, comprises blade (1), locating hole (2), rivet (3), rope hole (4), what it is characterized in that this grass cutter is shaped as V font, by shape, identical two the saw blade shape blades of size (1), is assembled.

2. grass cutter under water according to claim 1 is characterized in that: two blades (1) are that the rivet (3) by being positioned at front end links together, and the outer rim of two blades (1) has serrated edge.

3. grass cutter under water according to claim 1 is characterized in that: in locating hole (2), penetrate nylon wire in order to fix the angle between two blades (1), the shape of rope hole (4) is that circular arc is rectangular.
