Abstract

The utility model provides a tension spring-controlled hollow bar fish food dispenser. A cylinder cover of a charging opening is arranged at the upper end of a fish food cylinder body. At least two stay cables on the outer edge of the cylinder cover of the charging opening are hanged on a pivot hanging scroll. A discharging opening is arranged at the lower end of the fish food cylinder body. The fish food cylinder body and the discharging opening are in cone smooth transition. An inner casing pipe is fixed in the center of the cylinder cover of the charging opening. A tension spring is arranged in the inner casing pipe. An upper half-round hook of the tension spring is hanged on the pivot hanging scroll, and a lower half-round hook is hanged with an upper shackle of a slider. The outer circle of the slider is matched with the inner circle of an inner pipe of the inner casing pipe in a matching manner. The lower part of the slider is connected with a hollow bar. A soft string is arranged outside the closed plane of the lower end of the hollow bar. A dummy fish food bait is arranged at the tail end of the soft string. The tension spring is triggered by the dummy fish food bait to control the dispensing amount of the fish good, so as to realize that the fish food is automatically dispensed to fishes which are in hungry. When the fishes are eating, the oblong hole is indented into the discharging opening again by the tension spring, so as to ensure that the fish food is not dispensed too much to result in waste and prolong the cleaning period of the water in a fish pool.

Description

A kind of extension spring control hollow bar Apparatus for throwing in fish fodder

Technical field

The utility model relates to a kind of Fish bait applicator, relates to a kind of extension spring control hollow bar Apparatus for throwing in fish fodder especially.

Background technology

It is common a kind of leisure mode in the people in modern life that pet fish is raised; Along with living standard improves; Diversity is pursued in amusement; When people will go out the pet fish that tourism can't take into account in the family to be raised in a period of time, be badly in need of a kind of ability and substitute the controllable fish food of host automatic feeding machine, and do not have a kind of desirable easy fish food automatic feeding machine in the market.

Summary of the invention

The purpose of the utility model provides a kind of extension spring control hollow bar Apparatus for throwing in fish fodder, and it is not enough to have overcome prior art, adopts artificial fish food bait to trigger extension spring control hollow bar injected volume, realizes letting fish when hunger, get fish food automatic charging.

To achieve these goals, the utility model adopts following technical scheme: a kind of extension spring control hollow bar Apparatus for throwing in fish fodder, and the upper end of fish foodstuff cylindrical shell is the charge door cover; Have at least two oblique ropes of hanging to hang on the fulcrum hanging scroll on the charge door cover outward flange, the lower end of fish foodstuff cylindrical shell is a discharging opening, and the cone smooth transition is arranged between fish foodstuff cylindrical shell and discharging opening; As improvement: charge door cover center fixation has inner sleeve; Extension spring is arranged in the inner sleeve, and the upper semi-circle of extension spring is hooked on the fulcrum hanging scroll, and the lower half circle hook of extension spring shackle on the slide block of slide block; Slyness movingly in the interior pipe of the cylindrical of slide block and inner sleeve; The hollow bar of ining succession below the slide block has a soft cord outside the hollow bar lower end closed plane, the end of soft cord has an artificial fish food bait.

As further improvement: have a slotted hole on the described hollow bar lower semisection at least, the cylindrical of hollow bar and the endoporus of discharging opening are for being slidingly matched.

The fulcrum hanging scroll is arranged on the fish jar top, tiltedly hangs rope for two of fish foodstuff cylindrical shell and hang on the fulcrum hanging scroll, little block fish food leaves in the fish foodstuff cylindrical shell through the charge door of charge door cover.Whole fish foodstuff cylindrical shell is high up in the air to be hung, and has only artificial fish food bait to be immersed in fish jar horizontal line below.When fish feeling hungry when biting artificial fish food bait and moving about, haul hollow bar through soft cord and down drag, slotted hole is exposed at outside the discharging opening; Fritter fish food in the fish foodstuff cylindrical shell will be fallen in the water from slotted hole, discharging opening, and ducking in drink presents the wet fish food state that rolls; At this moment fish can unclamp artificial fish food bait; Go to rob and eat the wet fish food that rolls that ducks in drink, the reaction force of extension spring is up dragged hollow bar through slide block again, and slotted hole is once more in the indentation discharging opening.This automatic closing motion has been guaranteed that fish food can too much not thrown in and has been caused waste, also prolonged the cleaning cycle of water quality in the fishpond.

The utility model beneficial effect is: adopt artificial fish food bait to trigger extension spring and control fish food injected volume; Realized letting fish when hunger, get fish food automatic charging; When fish in the extension spring of when food again with slotted hole once more in the indentation discharging opening; Guaranteed that fish food can too much not thrown in and caused waste, also prolonged the water cleaning cycle in the fishpond.The utility model is novel, easy to use, simple in structure and be convenient to make and promote.
