Description

Novel multifunctional netting

Technical Field

The utility model relates to an aquatic products capture equipment field, specific novel multi-functional net of taking off suitable for gather fish shrimp, shellfish are biological that says so.

Background

Most of the aquatic shellfish live on the benthic land, or crawl and crawl on the water bottom, or dig holes in the substrate to hide, so most of the common fishing gear can not effectively catch the shellfish organism. A common net for taking off in rural areas comprises a bamboo pole handle, a bamboo chip net rack and a net body. When the hand-held pulling handle is used, the hand-held handle is held to throw the net to the water surface, and after the net is sunk to the water bottom, the hand-held pulling handle is pulled to the bank side by tightly clinging the net to the water bottom. Therefore, some benthic fishes, shrimps, crabs, screw lions and the like can be caught. For shellfish organisms hidden in a water bed, especially freshwater mussels, the common raking net cannot be contacted, so that the shellfish organisms cannot be caught.

For the freshwater mussels inhabiting in rivers and lakes, the freshwater mussels are caught by a foot-touch method in a common manual launching mode, time and labor are consumed, particularly in cold seasons, the water quality temperature is extremely low, and the freshwater mussels are difficult to bear by human bodies; the manual launching and fishing also has certain danger.

The patent document CN109588383A in the prior art discloses a domestic shellfish digging tool, which can collect mudflat shellfish creatures by arranging a U-shaped sheet-like sand digging blade in a U-shaped main fixing frame at the head of the device and assisting with a waist traction belt, but the device also has some disadvantages: the collection device is not provided, shellfish organisms at a deeper river bottom cannot be collected, the device cannot be folded, and the occupied space is larger.

SUMMERY OF THE UTILITY MODEL

To the problem that exists among the above-mentioned prior art, the utility model discloses a novel multi-functional net of taking off, the device realizes gathering the shellfish biology, the simple operation through taking off the collection device that the rake of net front portion set up the area cutting knife and semicircle form spiller, and this device adopts can dismantle, folding structure, portable.

The utility model discloses a specific technical scheme as follows: a novel multifunctional netting, comprising: the handle is detachably connected with the top of the net rack and the top of the support; the support connects the handle with the bottom of the netting, the net bag is sleeved on the periphery of the net rack, the net rack is divided into a top net rack and a bottom net rack, and the front end of the bottom net rack is of a semicircular vacant structure; an arc-shaped shovel blade is arranged at the circular edge of the semicircular vacant structure, the cutting edge of the shovel blade is arranged below, a long strip-shaped rake is arranged on the outer edge of the diameter of the semicircular vacant structure, rake teeth of the rake face downwards, a cutting knife is arranged at the front end of the rake, the cutting edge of the cutting knife is arranged above, and two ends of the rake are respectively bent upwards vertically and are used for connecting a support and a net rack; the support is of an arched elastic rod-shaped structure, and two ends of the support are respectively rotatably connected with the bent part of the rake; two ends of the net rack are respectively fixedly connected with the bent part of the rake; and two ends of the bottom net rack are respectively and rotatably connected with the bent part of the rake.

Furthermore, the two ends of the bracket are connected with the bent part of the rake by hinges.

Furthermore, the two ends of the bottom net rack are connected with the bent part of the rake by hinges.

Through setting up detachable handle portion and folding rack and support, collapsible packing up when making take off net storage and transportation reduces occupation space, portable.

The cutting knife can cut off aquatic weeds which hinder the netting from moving forward in the riverbed, and the advancing resistance is reduced.

Further, the net rack, the bracket, the scraper knife and the cutting knife can be made of aluminum alloy materials or other materials with high strength and high toughness and corrosion resistance.

Furthermore, the scraper knife and the bottom net rack can be integrally formed and manufactured.

Furthermore, the handle adopts a telescopic cylindrical long rod.

Adopt the beneficial effects of the utility model are that:

1. the front part of the device is provided with a rake with a cutting knife so as to achieve the purposes of raking out the shellfish and cutting off the aquatic weeds from the riverbed, and the shellfish is collected and gathered by a semicircular shovel knife, so that the operation is convenient.

2. The handle of the device can be dismantled, and the net body is collapsible, conveniently carries and stores.

3. The device adopts common material, simple structure, and the cost of manufacture is low.

4. The device uses cylindrical stock operation, easy operation, and need not operating personnel and go into water, alright carry out underwater operation.
