Description

Technical Field

[0001] The utility model relates to the technical field of artificial breeding of mandarin fish, in particular to a mandarin fish domestication and feeding device. Background Art

[0002] With the rapid development of the Huangshan stinky mandarin fish industry, demand for it has also increased, and local aquaculture has also taken off. The species used for Huangshan stinky mandarin fish is the large Culter chuatsi. Wild Culter chuatsi primarily feeds on live fish and shrimp, refusing to consume dead bait or formulated feed. They typically lurk at the bottom of the water, waiting for prey to approach before attacking, rather than actively seeking out prey. Therefore, acclimation is necessary during the fry stage to acclimate them to surface feed, thereby reducing the cost of rearing the mandarin fish. During this acclimation process, the feeding depth must be continuously adjusted from deep to shallow, and the initial live fish feeding must be transitioned to a mixed feeding of live and dead fish, then to a mixed feeding of dead fish and feed, and finally to pure feed. The existing method involves manual feeding, where bait is manually dropped through a vertical tube at a set depth. This not only causes variations in the drop depth, but also the bait (excluding the live fish) has poor fluidity, which does not meet the mandarin fish's feeding requirements. In addition, when feeding fish manually, the ratio of dead fish, live fish and feed is not easy to control and the operation is cumbersome. Therefore, it is necessary to design a device that is convenient for feeding fish to reduce the workload of personnel and facilitate accurate feeding. Summary of the Invention

[0003] The utility model aims to provide a feeding device for taming mandarin fish, which solves the problem that it is inconvenient to control the feeding ratio and depth during manual feeding.

[0004] The technical solution adopted by the utility model to solve the technical problem is: a feeding device for taming and feeding mandarin fish, comprising a feeding pipe, a bait temporary storage tank arranged at the upper end of the feeding pipe, and a feeding hopper arranged at the upper end of the bait temporary storage tank.

[0005] The feeding pipe includes a vertical pipe whose upper end is connected to the bait temporary storage tank and a horizontal discharge pipe connected to the bottom of the vertical pipe. One end of the horizontal discharge pipe is connected to a high-pressure water source or an air source; the vertical pipe is a multi-section telescopic rod structure.

[0006] In order to facilitate the acquisition of live bait fish and dead bait fish in different ratios, cathode rings and anode rings are respectively provided at both ends of the vertical tube. The cathode rings and anode rings are connected by wires and are provided with a pulse generator for outputting pulse signals and a pulse power amplifier for controlling the output voltage.

[0007] Specifically, the pulse waveform output by the pulse generator is a square wave, and the pulse duty cycle is 15 to 50%; the output frequency is 0.05 to 10 Hz. The output voltage of the pulse power amplifier is set according to the distance between the cathode ring and the anode ring, and the adjustment range is 4 to 10 v / cm. The specific value is selected within the adjustment range according to the required ratio of live fish to dead fish.

[0008] In order to guide the mandarin fish to eat, a player for playing the sound of water flow and the sound of intensive activities of fish schools is also installed on the outer wall of the bait temporary storage tank.

[0009] In order to facilitate adding water to soak the feed, the bait temporary storage tank is provided with a water inlet pipe for adding water and a timer.

[0010] The beneficial effects of the present invention are as follows: the present invention can put the bait for one-time feeding into the bait temporary storage tank, and then feed it to the specified depth through the feeding pipe, so as to realize precise feeding. The vertical pipe in the feeding pipe adopts a multi-section telescopic rod structure, which is convenient for adjusting the feeding depth. The horizontal discharge pipe is used for feeding, which can ensure the feeding depth of the bait. At the same time, a certain pressure is provided by a high-pressure water source or an air source, which can facilitate the removal of the bait in the vertical pipe and increase the speed of the bait entering the acclimation pool, so as to meet the habit of the mandarin fish to catch moving objects. The pulse generator and the pulse power amplifier can stun the bait fish in a certain proportion, thereby realizing the purpose of mixed feeding of live fish and dead fish. At the same time, the bait temporary storage tank can also be used to soak the feed, which is convenient for feeding.

[0011] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a structural diagram of the present utility model. DETAILED DESCRIPTION

[0013] Examples, such as Figure 1As shown, a feeding device for taming mandarin fish is placed in an acclimation pond and is used to feed mandarin fish. The specific structure of the feeding device includes a feeding pipe 1, a bait storage tank 2 arranged at the upper end of the feeding pipe 1, a feed hopper 3 provided at the upper end of the bait storage tank 2, and a discharge valve 8 provided at the bottom of the bait storage tank 2. The feeding pipe 1 includes a vertical pipe 11 whose upper end is connected to the bait storage tank 2 and a horizontal discharge pipe 12 connected to the bottom of the vertical pipe 11. The height of the vertical pipe 11 is adjustable, which is convenient for adjusting the feeding depth during the acclimation process. It is preferably a multi-section telescopic rod structure. For details, please refer to the structure of a telescopic fishing rod. One end of the horizontal discharge pipe 12 is connected to a high-pressure water source or air source 13. The negative pressure generated by the impact of the high-pressure water source or air source 13 can bring the bait fish or feed out of the vertical pipe 11 and flow out from the discharge port of the horizontal discharge pipe 12. The horizontal discharge pipe 12 can be used to well determine the water depth of each discharge, which is convenient for adjusting the feeding depth during domestication. At the same time, driven by the water flow, even dead fish and feed have a certain fluidity, imitating the swimming of live fish, which can satisfy the habit of mandarin fish to feed on swimming schools of fish. The bait temporary storage tank 2 is provided with a water inlet pipe 9 and a timer 10. After the feed enters the bait temporary storage tank 2 through the feed hopper 3, water is injected into the bait temporary storage tank 2 through the water inlet pipe 9 to soak the feed until it reaches the hardness required for mandarin fish to eat. The timer 10 is used to control the soaking time. After the soaking is good, the discharge valve 8 is opened to feed.

[0014] In order to stun or kill the bait fish in proportion, or to set the ratio of live fish and dead fish for feeding, so that the feeding of the mandarin fish changes from live fish feeding to bait feeding, a cathode ring piece 4 and an anode ring piece 5 are respectively provided at both ends of the vertical tube 11. The cathode ring piece 4 and the anode ring piece 5 are connected by a wire and are provided with a pulse generator 6 for outputting a pulse signal and a pulse power amplifier 7 for controlling the output voltage. The pulse signal is used to electrocute the bait fish, so that the bait fish is stunned or killed suddenly. Since fish have a positive reaction, that is, the habit of swimming towards the anode ring piece 5, the anode ring piece 5 is set at one end of the vertical tube 11 close to the horizontal discharge pipe 12, and the cathode ring piece 4 is set at one end of the vertical tube 11 close to the bait temporary storage tank 2.

[0015] The pulse waveform output by the pulse generator 6 is preferably a square wave with a pulse duty cycle of 15 to 50%; the output frequency is 0.05 to 10 Hz. The output voltage of the pulse power amplifier 7 is set according to the distance between the cathode ring piece 4 and the anode ring piece 5, and the adjustment range is 4 to 10 v / cm. The specific value is selected within the adjustment range according to the required ratio of live fish to dead fish, and the pulse voltage is adjusted and controlled during electric shock to obtain the required ratio of live fish to dead fish.

[0016] In order to enhance the stress response of the mandarin fish when eating and form a collective food-grabbing effect, a player 14 for playing the sound of water flow and the sound of intensive fish activities is also installed on the outer wall of the bait temporary storage tank 2, which can stimulate the mandarin fish to come out for food.

[0017] The above description of the present invention is provided as an example, in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described method. Any non-substantial improvements made using the method concepts and technical solutions of the present invention, or any application of the above-described concepts and technical solutions of the present invention to other situations without modification, are all within the scope of protection of the present invention.
