Description

Technical Field

[0001] The invention relates to the technical field of feed delivery equipment, in particular to an automatic feed delivery machine. Background Art

[0002] At present, there are the following problems in feeding aquaculture feed: In terms of feed form adaptability, there are significant differences between different fish species and growth stages: Species-specific needs: Carnivorous fish (such as mandarin fish) need high-protein powdered feed (particle size <0.5mm) in the larval stage to promote feeding, while herbivorous adult fish (such as grass carp) prefer 4-6mm pellet feed to improve digestion efficiency. Spring (March-May): High-protein powder (crude protein ≥45%) is needed to promote the growth of young fish during the water temperature recovery period; Autumn and winter (September-February): Fish metabolism slows down in low temperature environments, and the frequency of powder feeding needs to be reduced and slow-sinking particles should be used instead. Moreover, as time goes by, the food intake increases, and the amount of feed required by fish will also increase.

[0003] In the current aquaculture feeding, pellet feed is usually thrown by machine, and powder feed is manually poured into the water for supplementary feeding, because powder feed is easily blown back to the ship or the shore by wind, and it is not easy to throw it by machine. Powder feed needs to be weighed by hand and put into the water, which increases the labor cost.

[0004] To this end, the present application designs an automatic feeding machine, which can feed powdered feed and granular feed automatically and simultaneously at a fixed time and in a fixed quantity through one device to solve the above problems. Summary of the invention

[0005] In order to make up for the deficiencies in the prior art, the present invention provides an automatic bait throwing machine.

[0006] An automatic bait throwing machine, comprising a mounting plate mounted on the edge of a hull, characterized in that: A bait storage bin for storing powdered bait and granular bait is provided on the mounting plate. The powdered bait and granular bait in the bait storage bin are respectively fed into the feeding device. The bait amount is detected by the feeding amount detection device in real time. When the bait content in the feeding device reaches the required standard, the feeding device pours the powdered bait into the slide and sends it into the water, and sprinkles the granular bait onto the water surface.

[0007] Furthermore, in order to better realize the present invention, the bait feeding device includes a base plate, one end of the base plate is hinged to the mounting plate, the other end of the base plate is hinged with a telescopic rod, and one end of the telescopic rod is hinged in a telescopic rod mounting groove drilled on the mounting plate.

[0008] Furthermore, in order to better realize the present invention, a servo motor is installed on the base plate, and the motor shaft of the servo motor drives one end of the swing rod through a reducer, and the other end of the swing rod is hinged with a bait box connecting rod, and the end of the bait box connecting rod is fixedly connected to the bait box.

[0009] Furthermore, in order to better realize the present invention, a vertical support column is fixed on one side of the swing rod on the base plate, and a first limit plate is fixed on the other side of the swing rod; A second limiting plate and a third limiting plate are fixed at the position where the swing rod and the bait box connecting rod are hinged; When the bait box is in a state of receiving bait, the swing rod contacts the support column, and the bait box connecting rod contacts the second limit plate to keep the bait box horizontal; When the pellet feed is put in, the swing rod contacts the first limit plate, and the bait box connecting rod contacts the third limit plate.

[0010] Furthermore, in order to better realize the present invention, when the bait box is horizontal, the slideway installed obliquely on the mounting plate is located on one side of the bait box, and the telescopic rod is extended to drive the bait box to tilt, and the powdered bait is poured into the slideway.

[0011] Furthermore, in order to better realize the present invention, the release amount detection device includes an L-shaped bracket erected on one side of the bait box, a distance sensor facing downward to the bait box is provided on the top of the bracket, and a vibration motor is installed at the bottom of the bait box. The vibration motor vibrates to make the surface of the bait in the bait box smooth. After the smoothed bait is detected by the distance sensor, the current bait capacity in the bait box is judged by the distance; a control box is provided on the mounting plate, and a control chip in the control box controls and connects all electrical components.

[0012] Furthermore, in order to better realize the present invention, the bait storage bin is elevated by legs, and partitions are provided in the sub-bins to store powdered bait and granular bait respectively. Each bin is connected to a discharge pipe with an electrically controlled switch valve, and the end of the discharge pipe is located above the bait box and does not interfere with the movement of the bait box.

[0013] The beneficial effects of the present invention are: The device of the present invention can put powdered bait and granular bait at a fixed time and in a fixed quantity, which can greatly reduce the burden of manpower and improve the production efficiency of aquaculture.

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the accompanying drawings here can be arranged and designed in various different configurations.

[0017] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention.

[0018] Example 1: Structure and workflow of automatic bait throwing machine The automatic bait throwing machine of this embodiment is installed on the edge of the aquaculture boat, and the specific structure is as follows: The mounting plate 1 is fixed to the edge of the hull by bolts, and its surface is provided with a telescopic rod mounting groove 101. The mounting plate 1 is made of anti-corrosion aluminum alloy, and its surface is sprayed with a waterproof coating to adapt to the water environment.

[0019] The bait storage compartment 5 is elevated by legs 501 and is divided into two independent compartments: Powdered bait silo: It stores high-protein powdered feed with a particle size of less than 0.5 mm, and the bottom is connected to a discharge pipe 503 with an electric control switch valve.

[0020] Granular bait silo: It stores 4-6mm slow-sinking granular feed, and the bottom is also connected to the discharge pipe 503 controlled by the electric control switch valve.

[0021] The ends of the discharge pipes 503 of the two chambers are located directly above the bait box 307 and do not interfere with the movement trajectory of the bait box 307 (see Figure 1 ).

[0022] Mechanical linkage of bait throwing device 3 The base plate 301 is connected to the telescopic rod 102: one end of the base plate 301 is hinged to the mounting plate 1, and the other end is connected to the telescopic rod 102 through a hinge. The telescopic rod 102 is an electric push rod that can be extended and retracted along the telescopic rod mounting slot 101, driving the base plate 301 to swing around the hinge point (see Figure 2 ).

[0023] The servo motor 302 drives the swing rod 305: the servo motor 302 is fixed on the base plate 301, and drives the swing rod 305 to rotate around the axis through the reducer. The other end of the swing rod 305 is hinged to the bait box connecting rod 306, and the end of the bait box connecting rod 306 is fixed to the bait box 307.

[0024] Limiting structure: The base plate 301 is provided with a support column 303 and a first limiting plate 304, and the hinge between the swinging rod 305 and the bait box connecting rod 306 is provided with a second limiting plate 3051 and a third limiting plate 3052. When the bait box 307 receives bait horizontally, the swinging rod 305 contacts the support column 303, and the bait box connecting rod 306 abuts the second limiting plate 3051; when throwing pellet feed, the swinging rod 305 contacts the first limiting plate 304, and the bait box connecting rod 306 abuts the third limiting plate 3052 (see Figure 3 , Figure 4 ).

[0025] The detection process of the delivery amount detection device (4): A vibration motor 308 is installed at the bottom of the bait box 307, which makes the surface of the bait smooth after being started.

[0026] The distance sensor 402 on the top of the L-shaped bracket 401 detects the distance from the bait surface in the bait box 307 to the sensor in real time, and calculates the bait capacity by the distance change (for example: a distance reduction of 10mm corresponds to a bait weight of 200g).

[0027] The chip in the control box controls the opening and closing of the electric switch valve according to the preset feeding amount (such as 5kg of powder and 10kg of granular material per day in spring), ensuring that the feeding is stopped after the bait in the bait box 307 reaches the standard.

[0028] Bait delivery action: Powdered bait delivery: When the bait box 307 is horizontal and filled with powdered bait, the telescopic rod 102 extends, pushing the base plate 301 to tilt, and the bait box 307 tilts to pour the bait into the slide 6. The slide 6 is tilted at an angle of 30°, and the bottom extends below the water surface to prevent the powdered bait from being blown away by the wind (see Figure 3 ).

[0029] Particle bait throwing: The servo motor 302 drives the swing rod 305 to swing quickly, and the bait box 307 throws the pellet feed to the water surface under the action of centrifugal force. The throwing radius can reach 3-5 meters (see Figure 4 ).

[0030] The control box has a built-in PLC chip, which presets feeding modes for different seasons (such as high-frequency powder feed in spring and low-frequency granular feed in autumn and winter), receives real-time data from the distance sensor 402, and automatically adjusts the action timing of the electric control switch valve, servo motor 302 and telescopic rod 102.

[0031] Example 2: Adaptive adjustment function of bait throwing machine This embodiment further optimizes the control logic based on the embodiment 1: Environmental sensor integration: A water temperature sensor and a wind speed sensor are added to the mounting plate 1. The control box automatically switches the bait type according to the water temperature (for example, powder bait is disabled when the water temperature is below 15°C), and adjusts the inclination angle of the slide 6 according to the wind speed (replace the slide rail bracket 601 with an electrically controlled lifting rod) to prevent the powder from scattering.

[0032] Fish activity monitoring: Identify fish density through underwater cameras and dynamically adjust the single feeding amount to avoid bait waste.

[0033] Example 3: Maintenance and expansion functions Chamber cleaning design: The partition of the bait storage chamber 5 is a detachable structure, which is convenient for cleaning the compartments; the inner wall of the discharge pipe 503 is provided with an anti-caking coating.

[0034] Solar power supply module: The solar panel integrated on the top of the control box can provide auxiliary power for the equipment, which is suitable for aquaculture areas far away from shore-based power supply.

[0035] Summary of operation process: 1. Initialization: set the feeding time, bait type and feeding amount through the control box; 2. Feeding: The electronically controlled switch valve is opened, the bait enters the bait box 307, and the vibration motor 308 is started to smooth the surface of the bait; 3. Detection: After the distance sensor 402 determines that the bait amount has reached the standard, the electric control switch valve is closed; 4. Casting: According to the type of bait, drive the telescopic rod 102 or the servo motor 302 to complete the powder sliding or granule throwing; 5. Reset: The feeding box 307 returns to the horizontal position and waits for the next feeding instruction.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in the field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
