[0029] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:

[0030] Example 1

[0031] As shown in Figures 1, 2, and 3, a spiral-type quantitative feeder for laying hens to prevent feed spillage includes a feed hopper 1. The feed hopper 1 facilitates the storage and stable retention of feed within it. A battery storage box 13 is located at the bottom of the feed hopper 1, and a control box 14 is located on the side of the battery storage box 13. The control box 14 integrates a PLC controller, allowing for convenient control of the entire device's operation. The battery storage box 13, in conjunction with the control box 14, facilitates the operation and use of the entire feeder. A discharge pipe 17 is located at the bottom of the battery storage box 13, passing through it and communicating with the feed hopper 1, facilitating the discharge of feed from inside the feed hopper 1. The discharge pipe 17 is connected to a spiral feeder 2 for discharging feed from the feed hopper 1. A rotary motor 19 is located at the bottom of the battery storage box 13, and a support base 3 is located at the bottom of the feed hopper 1. The output end of the rotary motor 19 is connected to the top of the support base 3. This structure facilitates the operation of the feed hopper 1 by the rotary motor 19. Furthermore, the rotary motor 19 is integrated with a rotary encoder, which facilitates monitoring the rotation angle of the rotary motor 19. A feeding disc 4 is fitted onto the support base 3, and the feeding disc 4 is positioned at the discharge port of the screw feeder 2. The feeding disc 4 is designed to receive the feed discharged from the screw feeder 2.

[0032] As shown in Figures 2 and 3, the feed cylinder 1 has an opening at the top for easy feeding. Handles 11 are symmetrically located on both sides of the feed cylinder 1, facilitating gripping and rotation of the feeder. An observation window 12 is located on the side of the feed cylinder 1, running longitudinally from top to bottom, allowing for easy observation of the remaining feed level. The battery box 13 and control box 14 are integrated. The bottom of the battery box 13 has a connecting slot 18 for easy connection to the screw feeder 2.

The connecting plate 192 has multiple connecting holes 193 along its edge. The connecting plate 192 is connected to the support base 3 via bolts passing through the connecting holes 193. This structure facilitates fixing the drive shaft 191 of the rotary motor 19, while the rotary motor 19 itself is not fixed. When the rotary motor 19 is running, the stator windings generate a magnetic field, and the drive shaft 191 (rotor) rotates under the action of electromagnetic force. According to Newton's third law, the rotor experiences a driving torque from the stator (assuming clockwise rotation), while the stator experiences a reaction torque from the rotor (counterclockwise rotation). If the drive shaft 191 cannot rotate (rotor fixed), the reaction torque cannot be canceled out and will directly act on the rotary motor 19. If the motor body is not fixed, the reaction torque will drive the stator to rotate in the opposite direction (opposite to the rotor's expected direction). For example, when a handheld electric drill is unloaded, if the drill bit gets stuck (rotor fixed), the drill body will violently reverse direction; this is the result of the stator being subjected to the reaction torque.

The connecting line 222 and the connecting plug 223 facilitate the structural electrical connection between the feeding motor 22 and the battery box 13 and the control box 14.

[0034] As shown in Figure 5, the bottom edge of the support base 3 is provided with multiple legs 31, and the bottom of the legs 31 is provided with a fixing ring 32. The fixing ring 32 is provided with multiple fixing holes 33.

[0043] Working Principle: During use, sufficient feed is injected into the feed cylinder 1, and the battery box 13 is ensured to have adequate power. The entire feeder is then moved to the laying hen area, and the device is turned on via the control panel 16. After power-on, the PLC controller initializes and reads the current angle value of the rotary encoder. The operator sets parameters such as the intermittent rotation time interval of the feed cylinder 1, the rotation speed, and the feeding time and speed of the feeding motor 22 via the control panel 16. These parameters are then sent to the PLC controller for storage. When the PLC controller receives the start command, it first sends a signal to the rotary motor 19, which starts, and the feed cylinder 1 begins to rotate. Simultaneously, the PLC controller sends a signal to the driver of the feeding motor 22, which starts, and the screw feeder 2 begins feeding. The material enters the screw feeder 2 through the outlet of the feed cylinder 1. The rotary encoder detects the rotation angle of the feed cylinder 1 in real time and feeds the signal back to the PLC controller. When the rotation angle of the feed cylinder 1 reaches 360 degrees, the PLC controller immediately sends a stop command to the drivers of the rotary motor 19 and the feeding motor 22. The rotary motor 19 and the feeding motor 22 stop working, the feed cylinder 1 stops rotating, and the feeding process ends. After the feed cylinder 1 stops, the system enters an intermittent waiting phase. The waiting time is determined by the time interval of the intermittent rotation set by the operator. During the intermittent period, the PLC controller maintains its current state, waiting for the intermittent time to end. After the intermittent time ends, the system automatically enters the next work cycle, repeating the above process of rotation, feeding, stopping, and intermittent feeding to achieve intermittent rotation and feeding of the feed cylinder 1. Furthermore, the material discharged from the screw feeder 2 falls directly into the feed tray, allowing the laying hens to directly consume the feed around the tray.

[0044] In summary, compared with the prior art, this application provides a spiral feeder 2 at the bottom of the feed cylinder 1, and a rotary motor 19 is installed at the bottom of the feed cylinder 1. The rotary motor 19 drives the feed cylinder 1 to rotate, so that the feed cylinder 1 rotates while discharging feed. This allows the feed inside the feed cylinder 1 to be distributed around the feed cylinder 1, making it convenient for the laying hens to eat. At the same time, a feeding tray 4 is provided at the bottom of the feed cylinder 1, which can receive the discharged feed, making it convenient for the laying hens to eat. Furthermore, by controlling the operating time of the spiral feeder 2, feed can be discharged in a quantitative manner, making it convenient to feed the laying hens in a quantitative manner.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
