Description
Technical field
The present invention relates to fishing gear field, more particularly to a kind of automatic fish-feeding device.
Background technology
Current automatic fish-feeding device can be launched feed by self-timing within a certain period of time, be realized by the control of timer
Control to fish-feeding device feeding time interval, ensure that the uniform of each feeding amount, while also without artificially feeding is removed, subtract
The workload of fish is fed less.
Chinese patent application No. is 201510904567.6 discloses a kind of automatic fish-feeding device, including fish food supply,
Apparatus for throwing in fish fodder, conveyor drive and timer control the rotation of conveyer belt by timer, and fish food is put into fish fish jar
In, reduce the workload for feeding fish, allow people's leisurely ornamental fish of breeding fish, but only realized under the timing of timer to throwing
Food time interval is controlled, and reduces the workload for feeding fish, but food can be drifted in entire fish jar after not accounting for feeding
It is interior, lead to not concentrating for food, reduce the efficiency for feeding fish, not only result in the waste of feed, and can be because of some feeds
It is not consumed for a long time in corners and influences the water quality in fish jar.
Invention content
The object of the present invention is to provide a kind of loading mechanisms by being equipped with feeding dish and feeding ring arrives Feed Energy dispensing
Fixed place, which is realized, in fish jar efficiently feeds fish, does not cause the waste of fish food and can keep the not contaminated automatic fish-feeding of fish jar water quality
Device is to solve the deficiency in existing issue.The present invention is achieved through the following technical solutions goal of the invention：
A kind of automatic fish-feeding device, including loading hopper, cylindrical drum switch and loading mechanism, the cylindrical drum switch passes through cylinder
Side is connect with the exit normal of the loading hopper bottom, and cylindrical drum switch is equipped with through-hole, and cylindrical drum switchs the band in motor
It can connect through-hole and the egress selection of the loading hopper under dynamic, the loading mechanism can be contained to be opened by loading hopper through cylindrical drum
Close the fish food being shipped in water.The fish food launched as a result, by loading hopper can be fixed in loading mechanism concentrates feeding convenient for fish.
Further, the cylindrical drum switch includes cylinder shell, the cylinder inner casing being rotatably connected with the cylinder shell
And the motor being connect with the cylinder inner casing center, cylinder shell and the loading hopper integrally connected, the through-hole are arranged on
On cylinder inner casing, motor connect with controller and is rotated under the control of the controller.Motor is in the drive of controller as a result,
Lower rotation makes the through-hole on cylinder inner casing connect with loading hopper bottom to be timed feeding.
Further, the loading mechanism includes feeding ring, and the height of feeding ring is 2cm-5cm, and side is equipped with opening
It is connect by transfer canal with the bottom that the cylindrical drum switchs, light weight can be swum in the fish food collection of the water surface by feeding ring
In middle ring.
Further, the loading mechanism band further includes telescopic rod and is connected to immediately below the feeding ring by telescopic rod
Feeding dish, feeding dish profile height 3cm-5cm, feeding dish try to get to the heart of a matter area be feeding anchor ring product 1.5-3 times, as a result, hello
The side of food dish has certain altitude that can be drifted to avoid fish food, but excessive height is unfavorable for fish feeding, and in feeding ring and feeds
The requirement of different water surface elevations can be met between food dish by telescopic rod connection, since the area of feeding dish is much larger than feeding
Ring, though fish material in sinking watching because fish the slight perturbations of water are caused the fish material at feeding ring edge it is non-perpendicular whereabouts but still
It can fall into feeding dish, avoiding falling into the water drifting to corner fails to be taken by timely food and influence water quality.
Further, the telescopic rod is circumferentially uniformly distributed for 2-4 groups along the feeding ring, and the telescopic rod includes mutual
Engaging thick bar and thin bar, thin bar can back and forth stretch in thick bar.Thus, it is possible to being arranged as required to the group number of telescopic rod makes feeding
Drifting when ring and feeding dish avoid fish food heavy from top to bottom in same level always.
Further, it inside plastic material and ring body is hollow structure that the feeding ring, which is, thus, it is possible to make feeding ring matter
Amount is relatively light to be swum on the water surface to concentrate the light fish of floating food always.
Further, it is that the through-hole is straight to be additionally provided with opening between the bottom of the cylindrical drum switch and the transfer canal
The surge hopper of 2-4 times of diameter, the cylindrical drum of blocking when plunking down that will not be eaten as a result, when cylindrical drum, which switchs, to be opened because fish switch
The outlet of middle through-hole lower part.
Further, the junction of the transfer canal and the feeding ring is arc shape, and cambered design can eat fish
It is more smooth when being sent in loading mechanism by cylindrical drum switch.
Further, the edge of the loading hopper is uniformly connected with 4 groups of fixed links, and fixed link includes hard straight section and horizontal segment,
Each vertical section with the edge-perpendicular of loading hopper, each horizontal segment be connected at loading hopper center and with the loading hopper where
Plane it is parallel, the junction of horizontal segment is equipped with hook, and when hook is hung over above fish jar as a result, loading hopper can be in fixed link
Under the action of keep horizontal and stablize.
Further, the controller is equipped with display screen and button, and feed time and charging can be set by button
Speed can show set parameter on display screen.
Automatic fish-feeding device provided by the invention has the following advantages：
1st, traditional automatic fish-feeding device is combined with feeding dish and feeding ring, you can to launch feed automatically, reduce
Fish workload is manually fed to avoid reducing fish survival rate, but also can fish cuisine canon transfer canal be entered Sheng when forgetting feeding
The region that loading mechanism is drawn a circle to approve is fixed on after material mechanism, the fixed place that looks for food is provided for fish, realizes and efficiently feed fish, avoid institute
The fish food of throwing is not fixed to concentrate to drift everywhere and is not taken by timely food and influence fish jar water quality；
2nd, the floating fish of light weight can be eaten concentration by feeding ring in loading mechanism, and feeding dish can be by the sinking fish of quality weight
Food is concentrated, and is applicable to the feeding of fish at different depth between feeding dish and feeding ring by telescopic rod connection, is fitted
Wide with range, the fish food that can be applied to different quality is concentrated.
