In addition, existing fingerling classifying screen be all fixed size grades can not sized size.

Utility model content

The purpose of this utility model, which is that, provides a kind of classifying screen, the classifying screen weather resistance, it is light and handy, corrosion-resistant, can float In the water surface, easy-maintaining, and it is adjustable.

Technical scheme is：A kind of classifying screen, including screen cloth, rib and screen frame, screen cloth are connected on screen frame, rib and screen cloth It is connected, unadjustable region and adjustable region is provided with the screen cloth, adjustable region is arranged on screen bottom, non-adjustable Section region is centered around around adjustable region.

Preferably, the unadjustable region is made up of some non-adjustable zone fiber rods, every non-adjustable region Fiber rod or one end are connected with screen frame, and the other end is connected with rib, or both ends are respectively connected with rib.

Preferably, the adjustable region is made up of some adjustable area fiber rods, every adjustable area fiber rod It is made up of fiber rod body and removable connector, removable connector is more than 2, and fiber rod body is by being detachably connected Part is connected on rib.

Preferably, the removable connector is made up of fiber rod fixture, locking member and connector, locking member difference It is connected with fiber rod fixture and connector；The rib is located at offers chute and connector enters on the position of adjustable region Portal, connector manhole appendix connects with chute.

Preferably, the fiber rod fixture is stainless-steel pipe, it is enclosed on fiber rod body；Locking member is stainless steel Nut；Connector is stainless steel ball head screw.

Preferably, the classifying screen is additionally provided with two grip holes.

Preferably, covered with washer on described two grip holes.

Preferably, the washer is silica gel washer.

Preferably, the screen frame is ring-shaped round pipe.

Preferably, the rib is stainless pipe.

Compared with prior art, the beneficial effects of the utility model are：

(fiber service life is 15 times of bamboo life-span, and elasticity and toughness are better than bamboo number for the utility model weather resistance Times), light and handy (fiber rod weight is identical with bamboo weight), corrosion-resistant (no matter how use environment badly all can normal use (institute All be corrosion resistant material with stainless steel, fiber rod, silica gel), can bubble through the water column (use ring-shaped round pipe above screen cloth, suitable people The assurance of hand, and can are bubbled through the water column), easy-maintaining (being damaged under artificial or other irresistible power, can be with changing fiber rod), It is and adjustable.
