Description

Technical Field

[0001] This utility model relates to the field of eel farming technology, specifically to a feed dispensing device for eel farming. Background Technology

[0002] By utilizing the shallow water environment and biological resources of paddy fields, a certain number of eels are released into the fields. The eels eat weeds, pests, and plankton throughout the day. By constantly swimming and foraging, excreting manure, and muddying the water, they achieve the functions of pest and disease control, fertilization and growth promotion, weeding and cultivation, and indicator. Rice plants can absorb the unused residues from the eels, and the paddy fields provide the eels with a suitable water layer, habitat, and abundant biological resources. This realizes the recycling of materials and multi-level flow of energy in the paddy field ecosystem, improves the stability of the paddy field ecosystem, and achieves the comprehensive goals of "multiple uses of water, multiple harvests from one field, win-win for rice and fish, and stable grain production and increased efficiency." It also reduces the use of chemical fertilizers and pesticides in paddy fields (reducing fertilizer and pesticide use), improves the natural environment for green development of paddy fields, and enhances the utilization efficiency of paddy field resources.

[0003] However, in actual aquaculture, rice paddy aquaculture areas are often characterized by large areas and complex terrain (such as field ridges and uneven water depths). Traditional manual feeding methods have significant limitations: on the one hand, aquaculture workers need to carry feed back and forth in the fields, which is not only labor-intensive and inefficient, but also makes it difficult to ensure the uniformity of feed distribution, which can easily lead to uneven feeding of eels and affect their growth consistency; on the other hand, manual feeding is limited by labor costs and working time, making it difficult to achieve timed and quantitative feeding. As cold-blooded animals, the amount of food consumed and the growth status of eels are closely related to the scientific feeding rhythm. Improper feeding methods will reduce feed utilization and even pollute the aquaculture water. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a feed dispensing device for eel farming, which solves the problems of high labor intensity, low efficiency, and uneven dispensing when manually dispensing feed in rice paddy farming.

[0005] To achieve the above objectives, this utility model provides a feed dispensing device for eel farming, including a monorail installed at the edge of the paddy field and a transport trolley mounted on the monorail. The transport trolley is equipped with a mounting frame, which provides a stable foundation for the various components. A feed hopper is fixedly mounted on the mounting frame for storing the feed required for eel farming. A discharge port is located at the bottom of the feed hopper for convenient feed dispensing. A quantitative dispensing mechanism is installed on the mounting frame below the feed hopper to precisely control the amount of feed dispensed each time. A retractable guide tray is also provided on the mounting frame, whose length can be adjusted according to actual needs to accurately guide the feed to a designated area in the paddy field.

[0006] The feed hopper's inner wall has a gradually decreasing diameter at the bottom, which facilitates feed flow towards the discharge port and prevents feed residue inside. A sliding pressure block is installed inside the feed hopper, its bottom shape conforming to the bottom of the inner wall. As the pressure block slides downwards, it applies pressure to the feed inside, promoting smooth discharge from the discharge port and preventing feed clumping and blockage.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Preferably, the transport trolley includes a bottom support, which is U-shaped, and the monorail is T-shaped. A drive wheel is installed inside the bottom support, abutting against the top of the monorail. The drive wheel provides power, moving the transport trolley along the monorail. Stabilizing wheels are rotatably installed on both sides of the inner wall of the bottom support, abutting against the bottom horizontal section of the monorail. The stabilizing wheels enhance the stability of the transport trolley during movement, preventing the trolley from tilting or falling off.

[0009] Preferably, a battery box is fixedly installed on the top of the bottom support. The battery box is used to install a storage battery, which provides power support for electrical components such as the drive wheels and quantitative dispensing mechanism of the transport trolley, ensuring the normal operation of the device.

[0010] Preferably, the quantitative dispensing mechanism includes a turntable rotatably mounted at the bottom of the feed hopper, with the top of the turntable fitting snugly against the bottom of the feed hopper to prevent feed leakage from gaps. The turntable has several through holes, with the discharge port located along the movement path of these holes. As the turntable rotates, the through holes align sequentially with the discharge port, allowing feed to enter. A rotary motor is mounted on a mounting frame, with a drive gear fixedly connected to its output end. A gear ring meshes with the drive gear on the turntable. When the rotary motor operates, the meshing of the drive gear and the gear ring drives the turntable to rotate, achieving quantitative feed delivery.

[0011] Preferably, a measuring cup is installed inside the through hole for measuring feed. A reset plate is fixedly connected to one side of the mounting frame, below the turntable. A reset support plate is hinged to the inner wall of the through hole. When the reset support plate contacts the reset plate, it is located inside the through hole, with its bottom end against the top of the reset plate and its top end against the bottom of the measuring cup, providing support for the measuring cup. When the turntable rotates and the reset support plate disengages from the reset plate, the reset support plate flips downward under the weight of the feed, causing the feed in the measuring cup to fall onto the retractable guide plate.

[0012] Preferably, the metering cup includes a metering cylinder and a side skirt fixedly mounted on the top of the metering cylinder. A support ring for supporting the side skirt is fixedly connected to the inner wall of the through hole. The support ring fixes the metering cup in place. The top of the side skirt, the top of the metering cylinder, and the top of the turntable are flush, ensuring the stability of the turntable during rotation. The metering cup is available in various sizes, with different inner diameters of the metering cylinder and the same outer diameter of the side skirt, allowing for easy replacement of different sizes of metering cups and adjustment of the feeding amount according to the growth stage and feeding needs of the eels.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] By using a transport trolley to move along a single track, combined with a quantitative dispensing mechanism and a retractable feed tray, automated feed dispensing is achieved. Compared with manual dispensing, this greatly improves dispensing efficiency and reduces the labor intensity of farmers.

[0015] The metering cups in the quantitative feeding mechanism can be selected in different sizes according to needs to ensure that the amount of feed is accurate and consistent each time. At the same time, the stable movement of the transport cart ensures that the feed is evenly distributed in the paddy field, avoiding uneven feeding of eels and promoting their growth.

[0016] The retractable feed tray can be adjusted in length according to the actual conditions of the paddy field, and the single-track design can adapt to the complex terrain of the paddy field, ensuring that feed can be delivered normally in different environments. Attached Figure Description

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 As shown, this embodiment provides a feed dispensing device for eel farming, including a monorail 1 set at the edge of the paddy field and a transport trolley 2 set on the monorail 1. The transport trolley 2 is equipped with a mounting frame 3, which provides a stable mounting base for all components. A feed hopper 4 is fixedly mounted on the mounting frame 3 for storing the feed required for eel farming. A discharge port 401 is provided at the bottom of the feed hopper 4 for convenient feed output. A quantitative dispensing mechanism 5 is located on the mounting frame 3 and below the feed hopper 4, which can accurately control the amount of feed dispensed each time. A retractable guide tray 6 is provided on the mounting frame 3, the length of which can be adjusted according to actual needs to accurately guide the feed to a designated area in the paddy field.

[0025] The bottom diameter of the inner wall of the feed hopper 4 gradually decreases from top to bottom. This structural design facilitates the convergence of feed towards the discharge port 401, preventing feed residue inside the hopper. A sliding pressure block 402 is installed inside the feed hopper 4. The bottom of the pressure block 402 is shaped to match the bottom of the inner wall of the feed hopper 4. When the pressure block 402 slides downwards, it applies pressure to the feed inside the feed hopper 4, promoting smooth discharge from the discharge port 401 and preventing feed clumps from clogging the discharge port 401.

[0026] In summary, the improvements of this embodiment are: automated feeding reduces labor costs, and precise quantitative feeding improves feed utilization and avoids feed waste, thereby reducing breeding costs.

[0027] Based on the above, other structures also need to be disclosed in detail, such as:

[0028] First, the transport trolley 2 includes a bottom support 201, which is U-shaped, and the monorail 1 is T-shaped. A drive wheel 202 is installed inside the bottom support 201, abutting against the top of the monorail 1. The drive wheel 202 provides power, driving the transport trolley 2 to move along the monorail 1. Stabilizing wheels 203 are rotatably installed on both sides of the inner wall of the bottom support 201, abutting against the bottom horizontal part of the monorail 1. The stabilizing wheels 203 enhance the stability of the transport trolley 2 during movement, preventing the trolley from tilting or falling off.

[0029] Furthermore, a battery box 204 is fixedly installed on the top of the bottom support 201. The battery box 204 is used to install a storage battery, which provides power support for electrical components such as the drive wheel 202 of the transport trolley 2 and the quantitative dispensing mechanism 5, ensuring the normal operation of the device.

[0030] Secondly, the quantitative dispensing mechanism 5 includes a turntable 501 rotatably mounted at the bottom of the feed hopper 4. The top of the turntable 501 fits against the bottom of the feed hopper 4 to prevent feed from leaking out through gaps. The turntable 501 has several through holes 502, and the discharge port 401 is located on the moving path of the through holes 502. When the turntable 501 rotates, the through holes 502 align sequentially with the discharge port 401, allowing feed to enter the through holes 502. A rotary motor 503 is mounted on the mounting frame 3. A drive gear 504 is fixedly connected to the output end of the rotary motor 503. A gear ring 505 meshes with the drive gear 504 on the turntable 501. When the rotary motor 503 operates, the meshing transmission between the drive gear 504 and the gear ring 505 drives the turntable 501 to rotate, achieving quantitative feed dispensing.

[0031] Furthermore, a metering cup 506 is installed inside the through hole 502 for metering feed. A reset plate 507 is fixedly connected to one side of the mounting bracket 3, below the turntable 501. A reset support plate 508 is hinged to the inner wall of the through hole 502. When the reset support plate 508 contacts the reset plate 507, the reset support plate 508 is located inside the through hole 502, with its bottom end touching the top end of the reset plate 507 and its top end touching the bottom end of the metering cup 506, thus supporting the metering cup 506. When the turntable 501 rotates and the reset support plate 508 disengages from the reset plate 507, under the weight of the feed, the reset support plate 508 flips downward, causing the feed in the metering cup 506 to fall onto the retractable guide plate 6.

[0032] Finally, the metering cup 506 includes a metering cylinder 5061 and a side skirt 5062 fixedly disposed on the top of the metering cylinder 5061. A support ring 509 for supporting the side skirt 5062 is fixedly connected to the inner wall of the through hole 502. The support ring 509 fixes the metering cup 506. The top of the side skirt 5062, the top of the metering cylinder 5061, and the top of the turntable 501 are flush, ensuring the stability of the turntable 501 during rotation. The metering cup 506 is available in various sizes, with different inner diameters of the metering cylinder 5061 and the same outer diameter of the side skirt 5062, allowing for easy replacement of different sizes of metering cups 506 to adjust the feeding amount according to the growth stage and feeding needs of the eels.

[0033] In summary, the working principle of this solution is as follows:

[0034] Preparation stage: Load the eel feed into the feed bucket 4. Based on the eel's growth stage and feeding needs, select a suitable measuring cup 506 and install it into the through hole 502 of the turntable 501, ensuring the side skirt 5062 of the measuring cup 506 fits tightly against the support ring 509. Check the battery charge in the battery box 204 to ensure sufficient power.

[0035] Starting device: The starting device power supply and the storage battery supply power to each electrical component. The rotary motor 503 starts to work and drives the turntable 501 to rotate through the meshing of the drive gear 504 and the gear ring 505. At the same time, the drive wheel 202 of the transport trolley 2 rotates, driving the entire device to move slowly along the monorail 1.

[0036] Feed conveying: As the turntable 501 rotates, when the through hole 502 on the turntable 501 is aligned with the discharge port 401 of the feed bucket 4, the feed enters the metering cup 506 in the through hole 502 from the discharge port 401 under its own weight and the pressure of the lower pressing block 402 until the metering cup 506 is full.

[0037] Quantitative feeding: The metering cup 506 filled with feed continues to rotate with the turntable 501. When the rotation reaches the point where the reset plate 508 is disengaged from the reset plate 507, the reset plate 508 flips downward under the action of the feed's gravity, and the feed in the metering cup 506 falls onto the retractable guide plate 6 below.

[0038] Feed guidance: The retractable feed guide tray 6 guides the dropped feed to a designated area in the paddy field, completing one feed delivery.

[0039] Cyclic operation: As the transport trolley 2 moves continuously along the monorail 1, the turntable 501 rotates continuously, repeating the above-mentioned process of feed delivery, quantitative feeding and guidance, so as to achieve continuous and uniform feed delivery to the paddy field.

[0040] End phase: After the feed is dispensed or reaches the designated location, turn off the power to the device, and the transport trolley 2 and the quantitative dispensing mechanism 5 will stop working, thus completing this feed dispensing operation.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
