Description

Technical Field

[0001] The utility model belongs to the technical field of aquaculture auxiliary equipment, and in particular relates to automatic feeding equipment for indoor fish farming. Background Art

[0002] Fish, shrimp and other aquatic products are popular foods among consumers, and their quality determines the price. In order to improve the quality of aquatic products and save breeding land and costs, indoor aquatic product breeding technology has emerged, that is, setting the fish pond indoors, digging the pond body, the top of the pond protruding from the ground, and connecting the pond to a water circulation system.

[0003] The advantage of indoor fish farming technology is that it can centrally control water quality and adjust the indoor environmental temperature and water temperature, which is conducive to the prevention and treatment of various fish diseases, so that more fish can be raised in a relatively small water body. Traditional indoor fish ponds use artificial dumping feeding or automatic feeders to feed fish food. The fish food falling into the water in the above method is relatively concentrated, that is, a large amount of fish food gathers at the same position during feeding, resulting in dense and concentrated scramble for food by fish. At the same time, the internal space of the indoor fish pond is relatively small, resulting in some collisions. The fish will be stabbed by sharp fins, or hit the pool wall and get injured during the crowded scramble for food. If not handled in time, infection will occur, and even affect the water quality, bring about the spread of fish diseases, etc., seriously affecting the growth of fish in the pond; and the concentrated location of fish food will also cause some large fish to grab more fish food, and some weak fish cannot squeeze into the concentrated food location, and cannot get more food, affecting the growth and development of fish. The discharge port of some existing automatic feeding devices is also easy to be blocked, and the container device for storing feed will be damp, affecting the quality of fish food. Utility Model Content

[0004] The purpose of the utility model is to propose an indoor fish farming automatic feeding device to solve the problems that the feeding positions of indoor fish farming are relatively concentrated in the prior art, which causes injuries caused by the fish scrambling for food, the feed in the automatic feeding machine is easily damp, and the outlet of the automatic feeding machine is easily blocked. The device can scatter fish feed at different positions in the fish pond, avoid the fish swarming and scrambling for food, reduce the damage caused by scrambling for food, and ensure that the fish feed is dry, and eliminate the blockage of the outlet of the automatic feeding device. The device has a simple structure and is practical and effective.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An automatic feeding device for indoor fish farming, comprising a fish pond; also comprising a feed bin, a feeding pipe, a blower, an anti-blocking device and a control system; the feed bin is arranged beside the fish pond; the feeding pipe is connected to the bottom of the fish pond, and the front end of the feeding pipe extends downwardly to the top of the fish pond in an inclined manner; the outlet of the blower is provided with an outlet pipe; the outlet pipe is connected to an air inlet pipe; the air inlet pipe is connected to the feeding pipe; a hose is provided on the outlet pipe; an elliptical cam I is provided below the hose; the elliptical cam I is connected to a motor I; the anti-blocking device is arranged at the bottom of the feed bin; a discharge port is provided at the bottom of the feed bin, and a discharge solenoid valve is provided on the discharge port; the feeding pipe is connected to the discharge port; the blower and the discharge solenoid valve are both connected to a control system.

[0007] The fish pond is an indoor fish pond, the pond body of which is located underground and the top of the pond is higher than the ground; the feed bin is used to store fish feed; the bottom of the feed bin is conical, and the discharge port is located at the tip of the conical bottom, so that the fish feed is concentrated and falls into the feeding pipe; the feeding pipe leads the fish feed to the fish pond; the blower can blow air into the feeding pipe through the air inlet pipe, so as to blow the fish feed in the feeding pipe out a certain distance; the elliptical cam I rotates under the drive of the motor I, and at this time, the edge of one side of the longer diameter gradually turns to the position of contacting the hose, and in this process, the hose is gradually compressed, so that the air volume entering the feeding pipe through the air inlet pipe becomes smaller, and the distance the fish feed is blown out becomes shorter; as the elliptical cam I rotates, the degree of squeezing of the hose becomes smaller and smaller, and the air volume passing through becomes larger and larger, so that the distance the fish feed is blown out gradually becomes longer; the elliptical cam I is at its maximum When the long diameter side contacts the hose, the hose is squeezed the most, the air volume is the smallest, and the fish feed is blown out the shortest distance. Similarly, when the shortest diameter side of the elliptical cam I contacts the hose, the hose is squeezed the least, the air volume is the largest, and the fish feed is blown out the longest distance. This reciprocating process causes the fish feed to continuously change its landing point in the fish pond, thereby eliminating the problem of fish crowding and scrambling for food caused by the concentrated landing point of the fish feed. A timer and a weight sensor are also provided in the feed bin. The timer is used to calculate the time. When the set feeding time is reached, the discharging electromagnetic valve is opened. The weight sensor is used to sense the change in the amount of feed in the bin. When the amount of feed put in is sufficient, the discharging electromagnetic valve is closed. The device also includes a control cabinet, which is established based on PLC. The control system is integrated in the control cabinet, which is used to control and set the feeding time and feeding amount, and can also control the operation of each electromagnetic valve, motor, and blower.

[0008] As a further technical improvement, the anti-blocking device includes a housing, a vibrating push rod and an elliptical cam II; the housing is fixedly installed at the bottom of the feed bin; the vibrating push rod is telescopically arranged in the housing; a mounting plate is provided in the housing; a spring is connected between the vibrating push rod and the mounting plate; a transmission plate is provided at the bottom of the vibrating push rod; the elliptical cam II is close to the transmission plate; and a motor II is connected to the center of the elliptical cam II. The motor II drives the elliptical cam II to rotate, and the longer diameter side and the shorter diameter side of the elliptical cam II contact the transmission plate in turn, and the vibrating push rod is repeatedly pushed out through the transmission plate, and the vibrating push rod contacts and knocks the feed bin, causing vibration to prevent the outlet of the feed bin from being blocked; the spring can pull the vibrating push rod back.

[0009] As a further technical improvement, the air inlet pipe is also connected to a drying pipe; the drying pipe leads to the feed bin; an electric heating wire is arranged in the drying pipe; the electric heating wire is connected to the control system. The drying pipe can introduce air into the feed bin, and at the same time, with the heat heated by the electric heating wire, the air entering the feed bin is hot air, which helps to keep the feed bin dry; the heating power of the electric heating wire is moderate, and the air temperature passing through the drying pipe will not be too high, and the quality of the fish feed will not be affected.

[0010] As a further technical improvement, it also includes a silo support frame; the silo support frame is arranged at the bottom of the feed silo. The support frame is used to support the feed silo.

[0011] As a further technical improvement, the front end of the feeding pipe is arranged at a spray head; the spray head is flat. The spray head is used to spray the feed; the spray head is flat, so that the angle of the fish feed sprayed with the air flow becomes a fan shape, which is conducive to dispersing the feed particles.

[0012] As a further technical improvement, the front end of the air inlet pipe is divided into two groups of branch pipes; both groups of branch pipes are inclined to pass into the feeding pipe. The two groups of branch pipes are first bent upward, then extended downward and passed into the air inlet pipe to prevent fish feed from entering the branch pipes,

[0013] As a further technical improvement, the air inlet pipe and the drying pipe are both provided with ventilation solenoid valves, which are used to control the on and off of the air inlet pipe and the drying pipe.

[0014] As a further technical improvement, a feeding port is provided on the top of the feed bin, and the feeding port is used to add fish feed to the feed bin.

[0015] As a further technical improvement, the lower part of the hose is a soft folded material, and the upper part is a hard tube wall. Such a design can ensure that the folded material part is compressed, while the hard tube wall plays a supporting role, so that the entire hose will not be lifted up as a whole.

[0016] The method of using the above-mentioned indoor fish farming automatic feeding equipment:

[0017] Feeding and setting: put enough fish feed into the feed bin, and set the feeding time and the amount of fish feed to be fed through the control system;

[0018] Feeding: When it is time to feed the fish, the discharge solenoid valve opens, and the blower starts at the same time, blowing air into the feeding pipe through the air inlet pipe; the fish feed in the feeding pipe is blown out a certain distance by the air flow, and finally falls into the fish pond; the motor I drives the elliptical cam I to start, and at this time the elliptical cam I continuously squeezes the hose, and when the longest diameter side of the elliptical cam I contacts the hose, the squeezing of the hose is the largest, the air volume passing through the air inlet pipe is the smallest, and the distance the fish feed is blown out is the shortest; similarly, when the shortest diameter side of the elliptical cam I contacts the hose, the squeezing of the hose is the smallest, the air volume passing through the air inlet pipe is the largest, and the distance the fish feed is blown out is the longest, and so on, so that the landing point of the fish feed entering the fish pond is constantly changing, thereby eliminating the problem of fish crowding and scrambling for food caused by the concentrated landing point of the fish feed;

[0019] Anti-blocking: During the feeding process, the anti-blocking device is started intermittently, and the motor II drives the elliptical cam II to rotate. The longer diameter side and the shorter diameter side of the elliptical cam II contact the transmission plate in turn, and the vibration push rod is repeatedly pushed out through the transmission plate. The vibration push rod contacts and knocks the feed bin, causing vibration to prevent the outlet of the feed bin from being blocked; the spring can pull the vibration push rod back to prevent the discharge port from being blocked; when enough feed is fed, the discharge solenoid valve is closed, and the feeding is ended;

[0020] Drying: The drying tube can introduce wind into the feed bin, and with the heat from the electric heating wire, the wind entering the feed bin is hot air, which helps to keep the feed bin dry.

[0021] The technical solution of the utility model has the following beneficial effects:

[0022] 1. The utility model patent sets a blower, a hose and an elliptical cam I, which can continuously squeeze the hose during the rotation of the elliptical cam I, so that the passing air volume changes, thereby changing the air volume entering the feeding pipe, so that the distance where the fish feed is blown out changes continuously, avoiding the fish feed from falling in the same position, reducing the mutual squeezing of fishes when they are intensively competing for food, and avoiding injuries.

[0023] 2. The utility model can blow hot air into the feed bin through the drying pipe, thereby ensuring that the feed in the feed bin is dry and avoiding problems such as moisture and deterioration.

[0024] 3. The anti-blocking device of the utility model drives the vibrating push rod to reciprocate and hit the outer wall of the feed bin through the elliptical cam II to generate vibration, so that the fish feed is shaken off, thereby preventing the outlet of the feed bin from being blocked by fish feed particles.
