Description

Technical Field

[0002] In the livestock farming sector, the application of automated feeding equipment plays a positive role in improving feeding efficiency and reducing labor costs. Currently, farms commonly use various forms of automatic feeding devices to achieve timed and quantitative feed supply. These devices typically include basic components such as storage bins, conveying mechanisms, and control units. With the continuous expansion of farming scale, higher requirements are placed on the quantitative accuracy, structural reliability, and adaptability of feeding devices.

[0003] In existing mechanical feeding devices, guillotine or screw conveyor structures are typically used to control feed flow. Guillotine structures achieve on / off control through linear motion, but suffer from problems such as poor sealing and easy jamming. While screw conveyor structures can achieve continuous feeding, they are more sensitive to feed morphology and are prone to clogging when conveying feed that is prone to caking. These structures generally experience rapid wear and tear and require frequent maintenance during long-term use.

[0004] Therefore, it is necessary to design a feeding device that is simple in structure, easy to maintain, and easy to control. Utility Model Content

[0053] The embodiments of this utility model will be described in detail below.

[0054] This utility model discloses a mechanically powered quantitative feeding device. The device's basic structure, consisting of a hopper 2 and a switching system 3, utilizes a rotating wheel 31 to drive blades 311 to alternately block the flow cavity 211, forming a quantitative control mechanism based on rotational motion. Compared to traditional gate-type linear motion, this structure reduces the risk of jamming and, through its detachable installation method, facilitates equipment maintenance and cleaning. Details are as follows:

[0055] Figure 1 This is a schematic diagram of a mechanically powered quantitative feeding device. Figure 2 for Figure 1 Front view of a mechanically powered quantitative feeding device;

[0056] The mechanically powered quantitative feeding device of this embodiment is installed on wall 1 and includes a feed hopper 2 and a switching system 3. The function of wall 1 is to provide a stable installation foundation, which is usually a load-bearing wall of a pigsty or other breeding site. The function of feed hopper 2 is to store and temporarily hold feed, and it is detachably installed on wall 1 by screws. This detachable connection facilitates daily cleaning and maintenance.

[0057] Figure 3 This is a right view of the silo.

[0058] The upper part of the feed hopper 2 has a guide slope. The function of the guide slope is to guide the feed inside the feed hopper 2 to flow naturally to the discharge section 21 under the action of gravity, so as to avoid feed accumulation. In this embodiment, the guide slope is at a 45-degree angle to the horizontal plane. In other embodiments, the angle between the guide slope and the horizontal plane can also be 30 degrees, 40 degrees or 50 degrees. The specific angle can be adjusted according to the flowability of the feed. This structural design promotes the smooth flow of feed in the feed hopper 2, reduces the risk of residue, and ensures the continuity and uniformity of discharge.

[0059] The lower part of the hopper 2 has a discharge section 21, which is fixed to the hopper 2 by integral molding or flange connection. The discharge section 21 has a flow cavity 211 for feed to flow out, and the function of the flow cavity 211 is to form a controllable feed flow channel.

[0060] The flow cavity 211 includes a first cavity 212 for flowing feed and a second cavity 213 for accommodating the blade 311. The width of the second cavity 213 along the rotation axis of the wheel 31 is 10 mm smaller than the width of the first cavity 212 along the rotation axis of the wheel 31. In other embodiments, this width difference can also be 12 mm or 15 mm, as long as the width difference is at least 10 mm. This dimensional difference provides sufficient deformation space for the flexible baffle 313, avoiding material fatigue damage due to excessive compression. A rounded corner is formed at the connection between the sidewalls of the first cavity 212 and the second cavity 213. The function of the rounded corner is to reduce stress concentration and frictional wear. In this embodiment, the radius of the rounded corner is 5 mm. In other embodiments, the radius of the rounded corner can also be 6 mm or 8 mm, as long as the radius is not less than 5 mm. The rounded corner structure reduces the stress peak of the flexible baffle 313 when folded through a smooth transition, which helps to extend its service life.

[0061] Figure 4 This is a schematic diagram of the switching system (excluding the weight sensor). Figure 5 for Figure 4 Front view of the switch system (excluding the weight sensor); Figure 6 for Figure 4 Right view of the switching system (excluding the weight sensor); Figure 7 for Figure 4 A top view of the switching system (excluding the weight sensor).

[0062] The function of the switch system 3 is to precisely control the connection state of the flow cavity 211 in order to achieve quantitative feeding; it is set in the flow cavity 211 of the discharge section 21.

[0063] The switching system 3 includes a rotary wheel 31, a rotating shaft 32, and a motor 33.

[0064] The impeller 31 is formed by a circumferential array of multiple blades 311, which helps to achieve continuous alternating blocking action. In this embodiment, there are six blades 311 evenly distributed; in other embodiments, the number of blades 311 may be four, eight or twelve, and the specific number can be adjusted according to the feeding accuracy requirements.

[0065] The blade 311 includes a blade shank 312 fixed to a rotating shaft 32, and flexible baffles 313 installed on both sides of the blade shank 312 and extending outward. The blade shank 312 rigidly supports the flexible baffles 313 and is fixed to the rotating shaft 32 by a flat key connection; the blade shank 312 has a rectangular cross-section. The flexible baffles 313 achieve dynamic sealing and are made of nitrile rubber through a molding process, with a thickness of 3mm. This material choice gives the flexible baffles 313 good elasticity and wear resistance.

[0066] When the blade 311 is located in the first cavity 212, the flexible baffle 313 unfolds under feed pressure to seal the first cavity 212 and prevent feed leakage; when the blade 311 is located in the second cavity 213, the flexible baffle 313 folds under cavity constraints to seal the second cavity 213; this partitioned cavity design improves the sealing effect through the state switching of the flexible baffle 313.

[0067] The rotating wheel 31 is rotatably mounted on the side wall of the discharge section 21 via a rotating shaft 32. The function of the rotating shaft 32 is to transmit torque and support the rotational movement of the rotating wheel 31. One end of the rotating shaft 32 is connected to the output shaft of the motor 33 via a coupling. The function of the motor 33 is to provide stable and reliable rotational power; in this embodiment, the motor 33 is a three-phase asynchronous geared motor; in other embodiments, the motor 33 may also be a single-phase capacitor-run motor or a stepper motor.

[0068] When the rotor 31 rotates, the blades 311 alternately block the flow cavity 211, which is used to alternately open and close the flow cavity 211. This rotary blocking structure reduces the risk of jamming and improves the reliability of quantitative control.

[0069] The switching system 3 further includes a one-way bearing 34, which limits the rotation direction of the shaft 32 and the wheel 31 to prevent reverse rotation. It is mounted on the side wall of the discharge section 21 and fixed by a slot. The one-way bearing 34 is connected to the end of the shaft 32 away from the motor 33 via a spline drive. In this embodiment, the one-way bearing 34 adopts a roller structure. This one-way drive mechanism avoids feed backflow caused by accidental reverse rotation of the motor 33 or external interference, improving the stability and safety of equipment operation.

[0070] The switching system 3 also includes a controller (not shown in the figure), whose function is to coordinate the system operation and realize automated control. The controller is electrically connected to the motor 33 via a cable and is used to control the start, stop, and speed of the motor 33. The controller is a PLC controller, which realizes the control function through preset programs.

[0071] In this embodiment, the controller is configured to start the motor 33 at preset time intervals, ensuring the regularity of feeding. In this embodiment, the time interval is set to 6 hours; in other embodiments, the time interval can also be adjusted to 4 hours, 8 hours, or 12 hours, which can be programmed according to the specific needs of aquaculture.

[0072] In other embodiments, the switching system 3 also includes a weight sensor 35, which monitors the weight of feed flowing out of the hopper 2 in real time to achieve feedback control. It is installed below the discharge section 21 and fixed by a bracket. The weight sensor 35 is electrically connected to the controller via a shielded cable to reduce signal interference. The weight sensor 35 is a resistance strain gauge sensor with a range of 0-50 kg. In other embodiments, the weight sensor 35 can also be a capacitive or electromagnetic sensor, with the range selectable according to the feed intake requirements. The controller is configured to start the motor 33 when the measured value of the weight sensor 35 is less than a preset first threshold, and to shut off the motor 33 when the measured value of the weight sensor 35 is greater than a preset second threshold. In this embodiment, the first threshold is set to 5 kg, and the second threshold is set to 20 kg. This weight feedback control mode dynamically adjusts the feed intake according to the actual feed intake, improving the accuracy of feed utilization and reducing waste.

[0073] Overall, this utility model combines a wall 1, a hopper 2, a discharge section 21, a flow cavity 211, a switch system 3, a rotating wheel 31, a rotating shaft 32, a motor 33, blades 311, a blade holder 312, a flexible baffle 313, a first cavity 212, a second cavity 213, a one-way bearing 34, a controller, and a weight sensor 35. To a certain extent, it can achieve precise control and reliable operation of feed feeding. Through the synergy of the mechanical structure and the control system, the degree of manual intervention is reduced, and it has a certain positive effect on improving feeding efficiency and management level.

[0074] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
