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

[0021] Please see Figures 1-3 This utility model discloses a feed dispenser capable of timed feed dispensing, comprising a fixed base 1, a microcontroller 2 fixed to the front side of the fixed base 1, a servo motor 3 installed inside the fixed base 1, a feed dispensing tray 4 fixed to the top of the fixed base 1, and a strip-shaped discharge port 5 provided at the bottom edge of the feed dispensing tray 4. A feeding hopper 6 is installed on the top of the feed dispensing tray 4, and a material level sensor 7 is installed inside the feeding hopper 6. The output shaft of the servo motor 3 is connected to a spiral conveying shaft 8 via a coupling, and the spiral conveying shaft passes through the feed dispensing tray 4 and into the feeding hopper 6. A feeding blade 9 is installed at the lower end of the spiral conveying shaft 8, and the feeding blade 9 is located at the feed dispensing tray. In the feed pan 4, the microcontroller 2 performs open-loop speed control on the servo motor 3 and enables the motor to start and stop within a set time. When feeding is required, the servo motor 3 drives the spiral conveyor shaft 8 to rotate, so that the feed in the feeding hopper 6 enters the feed pan 4 under the push of the spiral blades. At the same time, the rotating feed-dispensing blades 9 are used to convert the feed into a loose state, so that the feed is thrown outward from the strip-shaped discharge port 5 at the bottom edge of the feed pan 4, which can avoid the crowding caused by concentrated feeding. This utility model has the characteristics of simple and compact structure, convenient installation and use, and saving manpower and material resources. The servo motor 3 and the material level sensor 7 are both electrically connected to the microcontroller 2.

[0022] Specifically, the fixed base 1 is a cylindrical structure, and the feed dispensing tray 4 is a conical tray structure.

[0023] In this implementation scheme, the fixed base 1 is used for support and fixation, and the feed dispensing tray 4 is used for scattering and dispensing feed.

[0024] Specifically, the bottom of the fixed base 1 is provided with mounting holes 10 around its perimeter, and a pad 11 is provided inside the fixed base 1, on which the servo motor 3 is fixed.

[0025] In this embodiment, the fixed base 1 is used to fix the machine to the designated plane through the mounting holes 10 and bolts. The pad 11 is a support structure used for the installation and fixing of the servo motor 3. The servo motor 3 is a high-performance actuator that can accurately convert electrical signals into mechanical motion. Its main function is to achieve high-precision closed-loop control of position, speed and torque.

[0026] Specifically, a torque sensor 12 is connected to the bottom end of the spiral shaft, and the torque sensor 12 is connected to the output shaft end of the servo motor 3 through a coupling. The torque sensor 12 is electrically connected to the microcontroller 2 through a wire.

[0027] In this embodiment, the main function of the torque sensor 12 is to convert the torsional torque on the mechanical parts into an electrical signal for accurate measurement, real-time monitoring and system control. If the screw conveyor shaft 8 or the feeding blade 9 is blocked by foreign objects (such as clumped feed), the torque sensor 12 will be used to trigger the motor to automatically cut off the power and alarm when it is overloaded.

[0028] Specifically, both the top of the fixed base 1 and the inner top of the feed dispensing tray 4 are provided with flanges 13, and the two are fixedly connected by bolts through the flanges 13.

[0029] In this implementation scheme, flange connections can connect different components together and provide necessary support to ensure the stability of the entire system.

[0030] Specifically, a mechanical seal 14 is installed on the feed dispensing tray 4, and the bottom end of the spiral shaft extends downward from the mechanical seal 14.

[0031] In this embodiment, the mechanical seal 14 is a device for sealing between the rotating shaft and the machine body. It is a device that prevents fluid leakage by maintaining a close fit and sliding relative to each other under the action of fluid pressure and the elastic force (or magnetic force) of the compensation mechanism and the cooperation of the auxiliary seal on at least one pair of end faces perpendicular to the rotating axis. By forming a stable sealing interface between two relatively rotating contact surfaces (dynamic ring and stationary ring), it prevents the fluid (feed) inside the equipment from leaking into the external environment.

[0032] Specifically, the cross-section of the feeding blade 9 is conical, and the bottom surface of the feeding blade 9 is close to the inner bottom surface of the feed dispensing tray 4. The strip-shaped discharge ports 5 are evenly distributed at the edge of the feed dispensing tray 4.

[0033] In this embodiment, the rotating feed blades 9 are used to convert the feed into a loose state, so that the feed is thrown outward from the strip-shaped discharge port 5 at the bottom edge of the feed feeding tray 4.

[0034] Specifically, the top of the feed dispensing tray 4 and the bottom of the feeding hopper 6 are both provided with pipe interfaces 15, and the two are connected by a flange of the pipe interface 15.

[0035] In this implementation scheme, flange connections can connect different components together and provide necessary support to ensure the stability of the entire system.

[0036] Specifically, the top of the feeding hopper 6 is fitted with a hinged cover 16, and the cover 16 is fitted with a viewing window 17.

[0037] In this embodiment, the feeding hopper 6 is used to store feed, while the flip cover 16 serves a protective function to prevent the feed from being contaminated by the external environment. The viewing window 17 is for convenient and intuitive observation of the inside of the feeding hopper 6.

[0038] In use, the microcontroller 2 (an integrated circuit typically composed of four main parts: a CPU responsible for executing instructions and performing calculations, a program memory for storing program code, a data memory for temporary data storage, an input / output interface for exchanging data with external devices such as sensors and actuators, and a clock circuit for providing timing signals to the controller and controlling the operating speed of each component) performs open-loop speed control of the servo motor 3, enabling the motor to start and stop within a set time. When feeding is required, the servo motor 3 drives the spiral conveyor shaft 8 to rotate, causing the feed in the feeding hopper 6 to enter the feed dispensing tray 4 under the push of the spiral blades. At the same time, the rotating feed-dispensing blades 9 are used to convert the feed into a loose state, allowing the feed to be thrown outward from the strip-shaped discharge port 5 at the bottom edge of the feed dispensing tray 4, avoiding the congestion caused by concentrated feeding. This utility model has the characteristics of simple and compact structure, convenient installation and use, and saving manpower and material resources.

[0039] In summary, this timed feed dispenser utilizes a microcontroller 2 to perform open-loop speed control on the servo motor 3, enabling the motor to start and stop within a set time. When feeding is required, the servo motor 3 drives the spiral conveyor shaft 8 to rotate, causing the feed in the feeding hopper 6 to enter the feed dispensing tray 4 under the push of the spiral blades. Simultaneously, the rotating feed-dispensing blades 9 are used to loosen the feed, allowing it to be scattered outward from the strip-shaped discharge port 5 at the bottom edge of the feed dispensing tray 4. This avoids the congestion caused by concentrated feeding. This invention features a simple and compact structure, convenient installation and use, and saves manpower and resources.
