Description

Technical Field

[0001] This utility model belongs to the technical field of feeding devices, and in particular relates to a feeding device for fish farming. Background Technology

[0002] Fish farming feed includes animal-based feed and plant-based feed. Animal-based feed mainly consists of fishmeal, blood meal, silkworm meal, silkworm pupa meal, earthworms, and insect larvae, which are rich in protein and fat. They can promote the rapid growth of carnivorous fish, enhance immunity, and are suitable for the fry stage, high-protein requirement stages, or the farming of valuable fish.

[0003] Plant-based feed mainly consists of soybean meal, corn flour, and wheat flour, providing fish fry with carbohydrates and plant protein as an energy source. It is suitable for herbivorous fish or adult fish during their maintenance period. Sometimes, trace elements such as calcium, phosphorus, and vitamin C are also added to prevent skeletal deformities and gill rot, and to improve the overwintering survival rate of fish fry.

[0004] Currently, automatic feeding devices are commonly used in fish farming to improve feeding efficiency and reduce labor costs. However, feed often contains easily sticky components such as oils and proteins, and it is prone to clumping in humid environments. Existing feeding devices often experience feed sticking to the walls, clumping, or even blockages, which not only wastes feed and reduces feed utilization but also affects the stable operation of the device. In addition, the discharge outlets of most existing feeding devices are fixed structures, which cannot be dynamically adjusted according to the actual distribution and feeding behavior of the fish. Fish fry are often distributed in different locations in the water body at different growth stages and under different water quality and temperature conditions. Fixed feeding ranges can easily lead to inaccurate feed distribution and uneven coverage, causing feed to settle and accumulate or resulting in low feeding rates. This not only reduces the feeding effect but also pollutes the water quality. Utility Model Content

[0005] The purpose of this invention is to solve the problems of feed clumping and blocking the device and poor feeding effect in the fixed feeding range of existing feeding devices, and to propose a feeding device for fish farming.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a feeding device for fish farming, comprising a feed hopper, a cloth cover connected to the bottom of the feed hopper, an anti-blocking mechanism, the anti-blocking mechanism including a scraper disposed inside the feed hopper, the scraper being configured to fit against the inner wall of the feed hopper, the scraper scraping off feed adhering to the inner wall of the feed hopper by sliding along the inner wall of the feed hopper, and an adjustment mechanism, the adjustment mechanism including an adjustment plate disposed inside the cloth cover, four of the adjustment plates being configured to rotate synchronously, the adjustment plates adjusting the tilt angle by rotating to adjust the feed distribution range.

[0007] Preferably, a rotating block is provided at the bottom of the material discharge shell, and multiple rotating blades are arranged around the outer wall of the rotating block along the axis, with one side of the rotating blades slidably connected to the inner wall of the material discharge shell.

[0008] Preferably, a lead screw is connected to the top of the rotating block, and a movable frame is provided outside the lead screw. A telescopic tube is sleeved on one end of the movable frame, and one end of the telescopic tube is in contact with the outer wall of one side of the scraper.

[0009] Preferably, a first motor is installed on the top of the material discharge shell, and the output end of the first motor is connected to one end of the lead screw.

[0010] Preferably, a connecting column is connected to one side of the outer wall of the adjusting plate, and a mounting shell is connected to the inner wall of the fabric cover. The outer wall of the mounting shell is provided with multiple through holes along the axis. One end of the connecting column passes through the through hole and is connected to a driven gear.

[0011] Preferably, a drive gear is rotatably connected to the inner wall of the bottom of the mounting housing, a second motor is installed at the bottom of the mounting housing, the output end of the second motor is connected to one side of the drive gear, and a protective cover is provided on the outside of the second motor.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0013] 1. In this utility model, by setting an anti-blocking mechanism, the scraper can closely fit and scrape over the inner wall of the feed hopper, preventing feed from being wasted due to moisture sticking to the inner wall of the feed hopper, thus improving feed utilization. At the same time, when the scraper rotates, the rod of the moving frame also rotates synchronously, stirring the feed accumulated in the feed hopper, preventing feed from sticking together and blocking the device, and ensuring the stable operation of the device.

[0014] 2. In this utility model, by setting an adjustment mechanism, the tilt angle of the adjustment plate can be dynamically adjusted according to the position and distribution of the fish fry during feeding, so that the feed can be placed in a position that the fish fry can eat more easily, thereby improving the coverage of feed placement, increasing the feeding rate of fish fry, and improving the utilization rate of feed.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 This utility model provides a technical solution: a feeding device for fish farming, including a feed hull 1, a cloth cover 5 connected to the bottom of the feed hull 1, an anti-blocking mechanism 4, the anti-blocking mechanism 4 including a scraper 404 disposed inside the feed hull 1, the scraper 404 being configured to fit against the inner wall of the feed hull 1, the scraper 404 scraping off the feed adhering to the inner wall of the feed hull 1 by sliding along the inner wall of the feed hull 1, and an adjustment mechanism 6, the adjustment mechanism 6 including an adjustment plate 602 disposed inside the cloth cover 5, four adjustment plates 602 being configured to rotate synchronously, the adjustment plates 602 adjusting the tilt angle by rotating to adjust the feed distribution range.

[0022] A rotating block 2 is provided at the bottom of the material discharge shell 1. Multiple rotating blades 3 are arranged around the outer wall of the rotating block 2 along the axis. One side of the rotating blades 3 is slidably connected to the inner wall of the material discharge shell 1.

[0023] The top of the rotating block 2 is connected to a lead screw 401. A movable frame 402 is provided outside the lead screw 401. A telescopic tube 403 is sleeved on one end of the movable frame 402. One end of the telescopic tube 403 is attached to the outer wall of one side of the scraper 404.

[0024] The top of the material feeding shell 1 is equipped with a first motor 405, and the output end of the first motor 405 is connected to one end of the lead screw 401.

[0025] Specifically, feed is placed into the feed hopper 1 through the top opening. The inner wall of the feed hopper 1 is set as an inclined surface, and the feed falls down along the inclined surface to the top of the rotating block 2. The cross-sectional shape of the blade 3 is arc-shaped. The first motor 405 drives the lead screw 401 to rotate through the output end. The lead screw 401 drives the rotating block 2 to rotate, and the blade 3 follows the rotation of the rotating block 2. When the feed falls along the arc surface of the blade 3, it is thrown outward by the centrifugal force generated by the blade 3. The external thread on the outer wall of the lead screw 401 meshes with the internal thread on the inner wall of the moving frame 402, causing the moving frame 402 to move along the direction of the lead screw 401. When the lead screw 401 rotates clockwise, the moving frame 402 moves downward along the direction of the lead screw 401. 2. The scraper 404 is moved downwards, and the surface of the scraper 404 is in contact with the inclined surface of the feed casing 1. During the downward movement of the scraper 404, the scraper 404 pushes the telescopic tube 403 inwards. A spring is installed inside the telescopic tube 403. The two ends of the spring are respectively connected to the inner wall of the telescopic tube 403 and the corresponding position of the outer wall of the moving frame 402. The spring is compressed, and the spring pushes the scraper 404 outwards through the elastic force, so that the scraper 404 keeps in close contact with the inclined surface. The width of the scraper 404 is equal to the width of the inclined surface. When the moving frame 402 moves to the bottom of the screw 401, the screw 401 continues to rotate, driving the moving frame 402 to rotate. The scraper 404 follows the rotation of the moving frame 402 and scrapes off the feed attached to the inclined surface.

[0026] It should be noted that the selection of the first motor 405 and the control unit in the above description are selected as needed. This part is well-known technology in the field and will not be described in detail here.

[0027] A connecting post 603 is connected to one side of the outer wall of the adjusting plate 602, and a mounting shell 601 is connected to the inner wall of the fabric cover 5. Multiple through holes are opened around the outer wall of the mounting shell 601 along the axis. One end of the connecting post 603 is inserted into the through hole, and a driven gear 604 is connected to one end of the connecting post 603.

[0028] A drive gear 605 is rotatably connected to the inner wall of the bottom of the mounting housing 601. A second motor 606 is installed at the bottom of the mounting housing 601. The output end of the second motor 606 is connected to one side of the drive gear 605. A protective cover 607 is fitted over the second motor 606.

[0029] Specifically, both the drive gear 605 and the driven gear 604 are housed within the mounting housing 601 to prevent water corrosion. The second motor 606 is housed within the protective cover 607 to prevent contact with water. The second motor 606 drives the drive gear 605 to rotate via its output end. The drive gear 605 meshes with the driven gear 604, causing the driven gear 605 to rotate. The driven gear 604, through the connecting column 603, drives the adjusting plate 602 to rotate. After being thrown out by the blade 3, the feed falls onto the top of the adjusting plate 602. The cloth cover 5 intercepts the feed to prevent it from being thrown out of the range of the adjusting mechanism 6. The adjusting plate 602 rotates to make an angle between the plate and the horizontal plane. The feed rolls outward along the outer wall of the top of the adjusting plate 602. When the adjusting plate 602 changes its angle with the horizontal plane by rotation, the position where the feed rolls out also changes accordingly.

[0030] It should be noted that the selection of the second motor 606 and the control unit in the above description are selected as needed. This part is well-known technology in the field and will not be described in detail here.

[0031] It should be noted that both the driving gear 605 and the driven gear 604 in the above description are bevel gears. The cone surface of the bevel gear coincides with the vertex of the friction wheel, and power transmission is achieved through pure rolling. This can realize power transmission between two intersecting shafts and is suitable for vertical shaft transmission scenarios. This part is a well-known technology in the field and will not be described in detail here.

[0032] Working principle: When in use, the staff puts the feed into the feed hopper 1, and then starts the first motor 405 to make the rotating block 2 drive the blade 3 to rotate and throw the feed out. The scraper 404 moves downward and scrapes the inner wall of the feed hopper 1 to prevent feed from adhering to the inner wall. Then the staff starts the second motor 606. The staff controls the second motor 606 according to the position and distribution of the fish fry, so that the adjusting plate 602 changes dynamically during the feeding process. The staff adjusts the tilt angle of the adjusting plate 602 so that the feed can be distributed to a suitable position. After feeding is completed, the staff turns off the second motor 606 and starts the first motor 405 in reverse to retract the scraper 404.
