Description

It is a kind of to pinpoint the hopper for launching feed for river crab

Technical field

Crabs production field is the utility model is related to, it is specifically a kind of to pinpoint the hopper for launching feed for river crab.

Background technology

River crab is subordinate to Crustachia, Eriocheir, be a kind of large-scale crustacean, and river crab often lives in caves Yu Jiang, river, lakes and marhshes Mud bank, nocturnalism, using fish, shrimp, spoil and cereal as food, in river mouth spawning and hatching, after developing into young crab, then the rivers that trace back On and, grow fresh water relaying is continuous, river crab it is Fresh ＆ Tender in Texture, be the food simply being loved by people, in natural conditions Under with drinking water grass, based on humus, addiction spoil, also eating spiral shell, freshwater mussel, worm, insect, also prey on small fish and shrimp once in a while, In artificial farming, feed is mainly manually fed, therefore the species of feed, quality and how many pairs of growing for river crab have very Big influence, smart, blue or green, thick reasonably combined principle should be adhered to during bait throwing in, and the species of feed for river crab mainly has three major types：It is first, complete Valency river crab special compound feed, second, animal fodder：Such as sea, fresh water small fish, each spoil, snail, bivalves, livestock and poultry Blood, fish meal, silkworm chrysalis etc., third, vegetalitas：Such as pasture and water class, duckweed, water peanut, eel grass, hydrilla verticillata, commercial feed class：Mountain Taro, potato, cereal, wheat bran, material chaff etc., the feed that river crab feeds typically wants a variety of feedstuffs to be fed after mixing, and feed is spread In feed table or selection on the slope close to waterline shoal, to observe river crab food, active situation, increase and decrease at any time is raised Material, river crab has stronger feeding habits of striving, therefore to set up an office more, river crab is eaten uniformly, avoids a part of complete small or Low Strive less than feed and cause to cut one another's throat, tradition feeds feed for river crab, takes the mode of shedding, and feed time spreads water bottom, feed It is scattered to be not easy to be ingested by river crab, not cause feed to be lost in, concentrate to launch typically in a small region and raised into stack Material, that is, facilitate river crab to ingest nearby, and and can reduces feed loss.

The content of the invention

To achieve the above object, the utility model devises a kind of hopper for pinpointing and launching feed for river crab.

The technical solution of the utility model is, a kind of to pinpoint the hopper for launching feed for river crab, it is characterized in that, the hopper by Long shank, hopper body, drawstring make, and the hopper body includes bucket wall and hopper bottom, and bucket wall is up big and down small loudspeaker The shape of the mouth as one speaks, hopper bottom are to be arranged at blocking up for bucket wall bottom, and the side upper limb of bucket wall is fixedly connected with long shank, long shank with Bucket wall is in 60-75 ° of angle, sets drawstring to consolidate ring in the hopper bottom of the lower section of long shank, consolidates the opposite side of ring in drawstring Folding, the bottom margin of the upper end connection bucket wall of folding, on the downside of the long shank of the top of the solid ring of drawstring are set in hopper bottom Drawstring steering ring is set, and one end of drawstring is tied up on the solid ring of drawstring, and drawstring is up along bucket wall, through edge after drawstring steering ring Long shank moves ahead, and through after the drawstring retainer ring at long shank handle, is fixed on handle end, drawstring is used to control hopper bottom Folding.

Beneficial effect：Using the utility model hopper, when feeding river crab, drawstring is fixed in drawstring retainer ring, made Hopper bottom is closed into the bottom of bucket wall, forms the hopper of bottom end closure, feed for river crab is placed in hopper, passes through long shank handle Hopper is deep at the feedstuff feeding point in water body, is unclamped drawstring, is opened hopper bottom, feed falls into feedstuff feeding point from hopper On, searched for food nearby for river crab, avoid when shedding feed feed from reducing the waste of feed from scattering and disappearing during water surface sinking, The utility model design is simple, easy to use, works well, there is promotional value.

Brief description of the drawings

Fig. 1 is the utility model structure chart.

In figure：1 handle, 2 drawstring retainer rings, 3 long shanks, 4 drawstrings, 5 drawstring steering rings, 6 bucket walls, the solid ring of 7 drawstrings, 8 Hopper bottom, 9 foldings.

Embodiment

Be described with reference to the drawings the utility model, it is a kind of to pinpoint the hopper for launching feed for river crab, it is characterized in that, the hopper by Long shank 3, hopper body, drawstring 4 make, and the hopper body includes bucket wall 6 and hopper bottom 8, and bucket wall 6 is up big and down small Broadening formation, for hopper bottom 8 to be arranged at blocking up for the bottom of bucket wall 6, the side upper limb of bucket wall 6 is fixedly connected with long shank 3, Long shank 3 and bucket wall 6 are in 60-75 ° of angle, and the solid ring 7 of drawstring is set in the hopper bottom 8 of the lower section of long shank 3, in the solid ring of drawstring Folding 9, the bottom margin of the upper end connection bucket wall 6 of folding 9, in the solid ring 7 of drawstring are set in the hopper bottom 8 of 7 opposite side The downside of long shank 3 of top drawstring steering ring 5 is set, one end of drawstring 4 is tied up on the solid ring 7 of drawstring, and drawstring 4 is along bucket wall 6 is up, through drawstring steering ring 5 after along long shank 3 move ahead, through after the drawstring retainer ring 2 at long shank handle 1, be fixed on The end of handle 1, drawstring 4 are used for the folding for controlling hopper bottom 8.

Beneficial effect：Using the utility model hopper, when feeding river crab, drawstring 4 is fixed in drawstring retainer ring 2, Hopper bottom 8 is closed into the bottom of bucket wall 6, form the hopper of bottom end closure, feed for river crab is placed in hopper, pass through long handle At the feedstuff feeding point that bar 3 is deep into hopper in water body, drawstring 4 is unclamped, opens hopper bottom 8, feed falls into feeding from hopper Material is fed on a little, is searched for food nearby for river crab, avoids the feed when shedding feed from from scattering and disappearing during water surface sinking, reducing feed Waste, the utility model design is simple, easy to use, works well, there is promotional value.
